Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of U.S. provisional Application No. 62/123,502 filed Nov. 20, 2014, and is a continuation-in-part of PCT Application No. PCT/US2015/061912 filed on Nov. 20, 2015, the disclosures of which are incorporated in their entirety by reference herein.

TECHNICAL FIELD

This disclosure relates to a portable desk system which may transition between at least a collapsed position and expanded position.

BACKGROUND

Conventional office chairs and other chairs that are used with desks in a school or home setting may offer very little control for either posture or position relative to a surface of the desk. Further, conventional school desks offer no adjustability to correct the relationship of the chair to the desk surface as best suited for the size of the person. Mobile lifestyles have expanded types of workspaces in comparison to past conventional settings. People seek comfort for the hours they spend working each day as well as portability. Typical desks may not provide users with feasible transport or storage options.

SUMMARY

A collapsible desk system includes first and second elongate members having a common central pivot and being pivotal relative to one another in a scissor-like manner. Each of the first and second elongate members has a first end for resting on an underlying surface and second end. A seat is attached to the second end of the first elongate member. A support member is cooperable with the first and second elongate members to selectively retain the elongate members in one or more crossed orientations. A column has upper and lower ends, the lower end pivotally attached to the second end of the second elongate member. A desk top is pivotally attached to the upper end of the column. The members, seat, column, and desk top are arranged with one another to transition between at least a collapsed and an expanded position.

The system may include a knee support mounted to one of the elongate members. The system may include a swivel mechanism to rotate the desk top about a swivel axis normal to the desk top. The desk top may define a rectangular shape and the swivel mechanism may be configured to enable the desk top to rotate ninety degrees. The swivel mechanism and the pivotal attachment of the desk top may cooperate to orient the desk top in an easel configuration in which the desk top is in a substantially upright position relative to the underlying surface. The desk top may pivot about a generally horizontal transverse axis relative to the column. The support member may be a strut pivotally connected to one of the elongate members and engageable with the other of the elongate members at a plurality of spaced apart locations in order to vary the desk height when the system is in the expanded position. The support member may be pivotally attached to one of the elongate members. The seat may be pivotally attached to one of the elongate members.

The system may define a height of less than one foot relative to the underlying surface when in the collapsed position. The desk top may define a side face having a groove extending about at least a portion of a perimeter of the desk top with the groove sized to receive a first fastener tab of an accessory. The groove may extend around substantially all of the perimeter of the desk top. The first fastener tab may define a mount cooperable with the accessory such that the accessory may rotate between at least a first and second position. The column may be telescopic to adjust a height of the desk relative to the underlying surface.

A lock mechanism may selectively engage the column in one or more positions. A lock mechanism at the pivotal attachment of the desk top to the column may selectively engage the desk top in one or more positions. A lock mechanism at the pivotal attachment of the column and the second elongate member may selectively engage the column in one or more positions. A front support member and a rear support member may rest on the underlying surface and each of the members may extend along an axis parallel with a transverse axis of the system. At least one of the elongate members may include a pair of transversely spaced apart elongate members on opposed transverse sides of the other elongate member. A knee support may be mounted to one of the elongate members.

A workspace system includes a desk top defining a top surface, a side surface, and a groove in the side surface extending about at least a portion of a perimeter of the desk top. The groove is sized to receive one or more fasteners of one or more corresponding components such that the one or more components do not extend over the desk top surface in at least a first position. The system may include a support structure supporting the desk top thereon with a lower portion for resting on an underlying surface and an upper portion. The system may include a seat assembly mounted to the upper portion of the support structure and having a seat and knee support. The support structure is arranged with the desk top to position a user proximate the top surface. The seat or knee support may be sized for removable covers to be attached thereto. The components may be selected from a group of a light device, a mobile phone dock, a tablet dock, a cup holder, a utensil receptacle, a speaker, a snack tray, a makeup mirror, a cord organizer, a book holder, a file receptacle, one or more clips, or an art supply holder. The one or more corresponding components may be pivotally mounted to the one or more fasteners such that the one or more corresponding accessories may pivot to extend over the top surface in a second position.

A reconfigurable desk system includes a support structure, a column, a desk top, a swivel mechanism, and a seat assembly. The support structure has first and second elongate members for at least partially resting on an underlying surface. The column has a first end mounted to one of the elongate members and a second end. The desk top is pivotally mounted to the column at a pivot assembly. The swivel mechanism is cooperable with the desk top to rotate the desk top about an axis normal thereto. The seat assembly is mounted to the support structure to position a user proximate the desk top. The pivot assembly and swivel mechanism are arranged with one another such that the desk may transition between a landscape configuration in which the desk is oriented in a substantially horizontal position relative to the underlying surface and an easel configuration in which the desk is oriented in a substantially upright position relative to the underlying surface. A knee support may be mounted to one of the elongate members and arranged with the seat assembly such that a posture of a user positioned thereon is defined by a substantially upright seated position optimal for spinal health of the user. The desk top may define a side face extending about a perimeter thereof and have a groove sized to receive a fastener tab of an accessory. An accessory may be attached at the groove and pivotal between at least first and second positions. The column may be pivotally mounted to one of the elongate members to adjust a location of the desk top relative to the seat assembly.

A collapsible desk system includes first and second elongate members, a seat, a diagonal support member, a column, a pivot assembly, and a desk top. The first and second elongate members have a common central pivot, and are pivotal relative to one another in a scissor-like manner. Each elongate member has a support member for resting on an underlying surface and an end. The seat is attached to the end of the first elongate member. The diagonal support member is cooperable with the first and second elongate members to selectively retain the elongate members in one or more crossed orientations. The column has upper and lower ends. The lower end is pivotally attached to the end of the second elongate member. The pivot assembly is mounted to the upper end of the column, includes a main component having a first extension with an arcuate cutout, and includes a lock mechanism comprising a pin for extension in to and retraction out of the arcuate cutout. The desk top is attached to the pivot assembly for rotational transition between a landscape position and an easel configuration. The elongate members, the seat, the column, and the desk top are arranged with one another to transition between at least a collapsed configuration and an expanded configuration. Engagement of the lock mechanism retains the pin within the arcuate cutout and disengagement of the pin retracts the pin from within the arcuate cutout so that the desk top may pivot between the collapsed configuration and the expanded configuration. The arcuate cutout may be defined by circular-shaped cutouts open to one another and extending in an arc relative to a center of a circular portion of the first extension. The lock mechanism may further include a knob coupled to a transfer assembly. The transfer assembly may be mechanically linked to a first slider and a second slider such that rotation of the knob moves the pin extending from one of the first slider and the second slider in to or out of the arcuate cutout. The main component may further include one or more arc-shaped openings for a fastener to extend therethrough to rotatably secure the main component to the desk top. The arc-shaped openings may be located upon the main component to facilitate rotation of the desk top independent of the main component. The desk system may further include an engagement mechanism having a T-knob. A base portion of the main component may define a first notch and a second notch. The desk top and the main component may be arranged with one another so the desk top is oriented in the landscape position when the T-knob is inserted into the first notch and so the desk top is oriented in the easel position when the T-knob is inserted into the second notch. The desk system may further include a pair of wheel assemblies. Each of the pair of wheel assemblies may be mounted for rotation to one of the support members of the first and second elongate members. Each of the pair of wheel assemblies may include a base component for securing to one of the support members, an intermediate component including a base portion having flaps, and a wheel mounted to the intermediate component for rotation upon an underlying surface. Each of the flaps may include a lip for gripping an edge of the base component to secure the intermediate component to the base component.

A pivot assembly for a reconfigurable desk includes a main component and a lock mechanism. The main component includes a base portion for securing to an underside of a desk top for rotation of the desk top and a pair of extensions each extending from the base portion and each including a circular portion defining an arcuate channel having circular cutouts open to one another. The lock mechanism includes a moveable pin for insertion in to and retraction out of the arcuate channel to retain the pivot assembly in at least first and second positions. The main component and the lock mechanism are arranged with a column assembly of the reconfigurable desk such that retention of the pivot assembly in the first position orients the desk top in a horizontal orientation relative to an underlying surface and retention of the pivot assembly in the second position orients the desk top in a substantially upright orientation relative to the underlying surface. The base portion of the main component may define first and second notches for receiving a T-knob of an engagement mechanism mounted to the desk top to retain the desk top in one of a landscape position and an easel position. The lock mechanism may further include a first slider, a second slider, and a spring disposed therebetween. The moveable pin may extend from one of the first slider and the second slider and the spring may be biased to push the moveable pin in to the arcuate channel. The lock mechanism may further include a knob mechanically linked to a transfer assembly. The transfer assembly may be mechanically linked to the first slider and the second slider such that rotation of the knob directs lateral translation of the first slider and the second slider to insert or retract the moveable pin from the arcuate channel. The desk top may define a top surface, a side surface, and a groove in the side surface extending about at least a portion of a perimeter of the desk top sized to receive one or more fasteners of one or more corresponding components such that the one or more components do not extend over the top surface in at least an upright position. A base portion of the main component may define one or more arc-shaped openings. Each of the one or more arc-shaped openings may be sized for a fastener to extend therethrough to rotatably secure the desk top to the main component such that the desk top may rotate independent of the main component.

A reconfigurable desk system includes a support structure, a column, a pivot assembly, a seat assembly, and first and second wheel assemblies. The support structure has first and second elongate members for at least partially resting upon an underlying surface. The column has a first end mounted to one of the first and second elongate members and a second end. The pivot assembly is mounted to the column, cooperable with a desk top to rotate the desk top about an axis normal thereto, and arranged with the desk top to transition the desk top between a substantially horizontal position relative to the underlying surface and a substantially upright position relative to the underlying surface. The seat assembly is mounted to the support structure to position a user proximate the desk top. Each of the first and second wheel assemblies is mounted to a separate end of one of the first and second elongate members for rotation upon the underlying surface. Each of the first and second wheel assemblies may further include a base component, a first intermediate component, a second intermediate component, a third intermediate component, a wheel, and a cap. The base component may be sized for mounting to the separate end of one of the first and second elongate members. The first intermediate component may define a through-hole sized for receiving a portion of the base component. The second intermediate component may include a base portion for insertion within the through-hole of the first intermediate component and include a first ledge. The third intermediate component may include a second ledge aligned with the first ledge to define a channel therebetween. The wheel may be secured to the third intermediate component and sized for disposal within the channel. The cap may have one or more mounts secured to the second intermediate component such that the third intermediate component and the wheel may rotate freely as a single component about the mounts. Each of the first and second wheel assemblies may further include one or more rollers each mounted for rotation about one of the one or more mounts and extending from the cap for contact with an inner surface of the third intermediate component such that the third intermediate component freely rotates upon the rollers. The base portion of the second intermediate component may include flaps each having a lip for gripping an edge of the base component to secure the second intermediate component to the base component. The desk top may define a top surface, a side surface, and a groove in the side surface extending about at least a portion of a perimeter of the desk top sized to receive one or more fasteners of one or more corresponding components such that the one or more components do not extend over the top surface in at least an upright position. Each of the first and second wheel assemblies may be arranged with the first and second elongate members so that the first and second wheel assemblies rotate upon the underlying surface when a user grasps and pulls the desk system by one of the first and second elongate members.

DETAILED DESCRIPTION

Embodiments of the present disclosure are described herein. It is to be understood, however, that the disclosed embodiments are merely examples and other embodiments can take various and alternative forms. The figures are not necessarily to scale; some features could be exaggerated or minimized to show details of particular components. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a representative basis for teaching one skilled in the art to variously employ embodiments of the present disclosure. As those of ordinary skill in the art will understand, various features illustrated and described with reference to any one of the figures can be combined with features illustrated in one or more other figures to produce embodiments that are not explicitly illustrated or described. The combinations of features illustrated provide representative embodiments for typical applications. Various combinations and modifications of the features consistent with the teachings of this disclosure, however, could be desired for particular applications or implementations.

Reference is first made to FIGS. 1 and 2 of the drawings which illustrate perspective views of the front and back of an example of a desk system, referred to generally as a desk system 10 herein. Components of the desk system 10 are arranged with one another such that the desk system 10 may transition between multiple configurations and positions. For example, the desk system 10 may transition between at least a collapsed or folded position and an expanded or open position. The desk system 10 may include an integrated seating and work surface that can easily fold for simple and convenient storage and easy transport. When assembled, the system includes an adjustable work desk with an integrated clip system that allows for a variety of desk and work accessories to be attached to the edge of the work surface leaving the entire work surface clear. These accessories may provide, for example, storage, lighting, entertainment, and other useful devices.

In one example of the desk system 10, there is no tool assembly required and as previously indicated it can readily be folded flat for easy storage and portability and quickly opened and adjusted to a desired position or configuration. The desk system may include a top with a channel cut and a plastic trap which permits insertion and attachment of the various accessories. The desk system 10 may provide a custom workplace without sacrificing desk space. Adjustability of the desk system 10 may accommodate a variety of different sized users and may positively influence a user's posture while seated.

While several modifications will be illustrated and described the common elements will be given the same numerals. It is noted that various elements will change in detail but their functions will not.

Continuing to refer to FIGS. 1 and 2, the desk system 10 includes a desk top 12 supported by columns consisting of inner and outer columns 14, 16. The inner column 14 is connected to a desk top 12 by a pivot assembly 18 so the desk top 12 can be pivoted relative to the inner column 14. The inner column 14 may have an upper end and the outer column 16 may have a lower end. The inner column 14 and the outer column 16 may have a telescoping relationship. Various shapes may be suitable for the desk top 12. For example, the desk top 12 may define a rectangular or square shape. A configuration of the desk top in FIG. 1 may be referred to as a landscape configuration herein. A work surface lock out mechanism 62 (see FIG. 9b) may be provided to lock the desk top 12 in position when the assembly is moved to one or more positions including an open position. For example, the lock out mechanism 62 may be selectively engaged to orient the desk top 12 in the one or more positions. It is contemplated that other suitable lock mechanisms may be available to secure the desk top 12 and inner column 14 in a position.

The inner and outer columns 14, 16 may define openings (not shown) for a pin 20 to extend therethrough and retain the columns 14, 16 in the desired position. For example, the desk top 12 may translate to adjust a distance between an underlying surface and the desk top 12 and/or to adjust a distance between the underlying surface and a seat assembly 26.

A pivot assembly 24 assists in enabling pivotal movement of the outer column 16 and a knee support assembly 22. The knee support assembly 22 may include one or more knee pads to assist in supporting a user positioned adjacent the desk top 12. It is contemplated that the knee support assembly 22 may be a single component or may include more than one component, such as multiple knee pads.

We turn now to the seat assembly 26 which is connected to a seat 28. The seat 28 is connected to a front support base 30 through a dual column assembly 32. The dual column assembly 32 may include a first elongate member 33. The first elongate member 33 may have a first end for resting on the underlying surface and a second end. The dual column assembly 32 may include two first elongate members 33 spaced apart from one another. The seat 28 may be mounted to the dual column assembly 32 for pivotal movement. For example, the seat 28 may be mounted to the second end of the first elongate member such that when the desk system 10 is oriented in a collapsed position (further described below) the seat 28 may pivot to assist in providing a more compact configuration of the desk system.

The knee support assembly 22 may be connected to a rear support base 34 through a column assembly 36. The seat assembly 26 may include a second elongate member 37. The second elongate member 37 may include a first end for resting on the underlying surface and a second end. The seat assembly 26 may include two second elongate members 37. The first elongate member 33 and the second elongate member 37 may share a common pivot and be pivotable relative to one another in a scissor-like manner. For example, the first elongate member 33 and the second elongate member 37 may share a pivot 39.

To permit pivotal movement of the seat assembly 26 and the knee support assembly 22 there is provided a pivot assembly 38. For example, the pivot assembly 38 may include a link 42. To facilitate positioning of the seat assembly 26 relative to the knee support assembly 22 a support plate 40 may be secured between braces 36a and 36b of the column assembly 36. The link 42 may be provided between a plate 40 and the seat assembly 26. One end of the link 42 may be pivotally connected to the seat assembly 26 at a pivot 44. The link 42 may operate as a support member and be cooperable with the first elongate member 33 and the second elongate member 37 to selectively retain the elongate members in one or more crossed orientations. The other end of link 42 may have a transversely extended rod 46 connected thereto which may be adjustably positioned between slots in plate 40 to receive rod 46 in various positions. For example, the link 42 may be a strut pivotally connected to one of the elongate members and engageable with the other of the elongate members at one or more spaced apart locations in order to vary a height of components of the desk system 10. The link 42 may also be pivotally attached to one of the elongate members.

FIGS. 3 and 4 provide a front view and a back view of the desk system 10. The components thereof are appropriately numbered.

The first and second elongate members 33, 37, the seat 28, the inner and outer columns 14, 16, and the desk top 12 may be arranged with one another to transition between at least a collapsed position and an expanded position. For example, FIG. 5a is a schematic view of the desk system 10 in the expanded position and FIG. 5b is a schematic view of the desk system 10 in the collapsed position. The desk system may define a height of less than one foot relative to the underlying surface when in the collapsed position.

FIG. 6 shows the desk system 10 in the collapsed position for storage or transport. For example, the desk system 10 may fit under a user's bed or within a user's closet when in the collapsed position. As another example, the desk system 10 may be more conveniently transportable when in the collapsed position in comparison with the expanded position.

FIG. 7 shows another example of an embodiment of the desk system 10 oriented in the expanded position. In this example, the knee support assembly 22 is shown as a single component mounted to the second elongate member 37.

Shown attached to the desk top 12 are various accessories including a fan 54, speakers 56, and a lighting system 58. Examples of other accessories which may be removably attached to the desk top 12 include, but are not limited to, a mobile phone dock, a tablet dock, a cup holder, a utensil receptacle, a speaker, a snack tray, a makeup mirror, a cord organizer, a book holder, a file receptacle, one or more clips, or an art supply holder. The seat 28 and the knee pads of the knee support assembly 22 are of a different design than FIGS. 1 through 4 but the components thereof are otherwise similar.

FIG. 8 illustrates another embodiment showing slightly different designs of various accessories.

FIG. 9a illustrates another embodiment that includes similar components as the other embodiments but takes slightly different shapes and sizes that indicate the wide variations that are possible involving applicant's novel concepts.

FIG. 9b is a detailed view of the open work surface lock-out mechanism 62 for locking the work surface in a position during use.

FIG. 9c shows the main arm dual lock-out system 60 for locking the main column in position during use.

FIGS. 9d and 9h illustrate the novel slot system for attaching various accessories. For example, the desk top 12 may define a side face 67 extending about a perimeter thereof. The side face 67 may have a groove 69 extending about at least a portion of the perimeter of the desk top 12. In another example, the groove 69 may extend around substantially all of the perimeter of the desk top 12. The groove 69 may be sized to receive a fastener tab of one of the accessories. The fastener tab may be mounted to the respective accessory for pivotal movement. For example, the pivotal relationship between the fastener tab and respective accessory may be such that the accessory may pivot between at least a first position in which the accessory does not extend over a portion of the desk top 12 and a second position in which the accessory extends over a portion or contacts the desk top 12. For example, in the collapsed position the accessory may extend over and contact the desk top 12 for storage or transport purposes.

FIG. 9e shows an exploded view of various examples of components of the desk system 10.

FIG. 9f is a side perspective view of the embodiment shown in FIG. 9a.

FIG. 9g includes partial perspective views of the desk system 10 including a view having a user positioned thereon. In this example, a posture of the user positioned on the desk system 10 may be defined by a substantially upright seated position optimal for spinal health of the user.

FIG. 9h is a partial perspective view showing a side portion of the desk top 12.

FIG. 9i is a perspective view of the embodiment shown in FIG. 9a shown partially collapsed.

FIG. 9j is a partial perspective view of the embodiment shown in FIG. 9a.

FIGS. 10 and 11 show an example of a swivel mechanism which may assist in rotating the desk top 12 relative to the supporting structure and about an axis normal to the desk top 12. Turning now to FIG. 10 there is illustrated an enlarged perspective view of the pivot assembly 18. It is to be noted that the pivot assembly 24 is similar to the pivot assembly 18.

In FIG. 10 there is shown the inner column 14 connected to a shaft 70 which is rotatably mounted. Connected to one end of the shaft 70 is a toothed wheel 72 which engages a mating toothed member 74. A handle 76 is connected to a shaft 78 that is threaded into a knob 80 in a fixed position. The handle 76 may be turned counter clockwise and the toothed wheel 72 may be loosened and disengaged from the toothed member 74 such that the column 14 is free to rotate and move the desk top 12 to a desired angled position. The handle 76 may be turned clockwise to lock the toothed wheel 72 and the toothed member 74 together and lock the desk top 12 in a fixed position.

The pivot assembly 24 for permitting movement of the column 16 is similarly designed to adjust or retain the column assembly in a fixed position.

The desk top 12 may be rotated relative to an axis normal to the desk top 12. For example, the desk top 12 may rotate between 90 and 180 degrees. Bottom surface projections 82 of the desk top 12 may fit into corresponding openings that are formed in a plate to which is secured toothed member 74. In a normal fixed position, a first plate 86 and a second plate 81 may be retained in their relationship by the knob 90 to which is connected a shaft (not shown) which when loosened permits disengagement of the projections 82 from the openings 84 which permits rotation of the desk top 12. When the plates 81, 86 are in their relocated position the knob 90 may be tightened to retain the plates in the new position.

FIG. 12 is a perspective view of the desk system 10 shown in a collapsed position.

FIGS. 13 through 15 show another example of the desk system 10. FIG. 13 shows the desk system 10 in the expanded position with the desk top in the landscape configuration and various accessories mounted thereto. FIG. 14 shows the desk system 10 in an easel configuration in which the desk top 12 is oriented in a substantially upright position relative to the underlying surface. Artists are one example of a type of user which may utilize the easel configuration. In this configuration, accessories, such as a light, speakers, and a utensil receptacle may be mounted to the desk top 12 via the groove 69 and respective fastener. FIG. 15 shows the desk system 10 in the collapsed position for transport or storage.

FIGS. 16 and 17 show an example of an accessory fastener, referred to generally as an accessory fastener 100 herein. The accessory fastener 100 may include a mount 104, a first fastener tab 108, and a second fastener tab 110. The accessory fastener 100 may be mounted to a desk top, such as the desk top 12. For example, the first fastener tab 108 may be sized for disposal within a groove, such as the groove 68 of the desk top 12. The second fastener tab 110 may be arranged with the first fastener tab 108 to assist in orienting the accessory fastener 100 relative to the desk top 12. An accessory, such as an accessory 112 may be mounted to the accessory fastener 100 at, for example, the mount 104. The mount 104 may be, for example, a nub or pin sized for reception within the accessory 112 such that the accessory 112 may rotate about an axis in line with the mount 104. For example, FIG. 17 shows an example in which the accessory 112 may rotate between a position in which the accessory 112 does not extend over a portion of the desk top 12 to a position in which the accessory 112 extends over the desk top 12. FIG. 18 shows an example in which multiple accessories are folded onto the desk top 12 where the desk system 10 is in the collapsed position.

The desk systems described above provide users with a workspace option in which a stored desk system may be easily opened as a fully assembled product and adjust to fit their body. Transition between the various positions and configurations does not require additional parts or tools. Accessories may attach to the desk simply and allow the user to customize their workspace according to work needs and style and without obstructing work space of the desk top. The accessories may also fold against the desk top storage. Additionally, the seat and knee supports may positively influence the user's posture while working at the desk and may be adjusted to accommodate various user body types and sizes.

FIGS. 19 and 20 illustrate another example of a desk system referred to generally as a desk system 200. The desk system 200 may be reconfigured between expanded and collapsed configurations as described above. In FIG. 19, the desk system is shown in the expanded configuration and in FIG. 20 the desk system 200 is shown in the collapsed configuration. The desk system 200 includes a desk top 206 mounted for pivotal movement to a column assembly 208. For example, the desk top 206 may be mounted to the column assembly 208 by a pivot assembly (the pivot assembly shown in FIGS. 23 through 26). The pivot assembly may assist in enabling the desk top 206 to transition between multiple positions such as a landscape position and an easel position as further described below. The desk top 206 defines a top surface, a side surface, and a groove in the side surface extending about at least a portion of a perimeter of the desk top sized to receive one or more fasteners of one or more corresponding components such that the one or more components do not extend over the top surface of the desk top 206 in at least a first position.

The column assembly 208 may be mounted to a first elongate member 214 or a second elongate member 216. The first elongate member 214 and the second elongate member 216 may be arranged with one another for a scissor-type movement to assist in transitioning the desk system 200 between the expanded configuration and the collapsed configuration. A knee support assembly and a seat assembly may be mounted to one or both of the elongate members to support a user. For example, the knee support assembly may include a first knee support 220 and a second knee support 222. The seat assembly may include a seat 226 mounted to the second elongate member 216. The seat 226 may be adjustable to accommodate various sizes of users to position the user in a comfortable position relative to the desk top 206. A diagonal support member 228 may extend between the first elongate member 214 and the second elongate member 216 to retain the elongate members in position relative to one another.

A first support member 240 extends from the first elongate member 214 and a second support member 242 extends from the second elongate member 216. The first support member 240 and the second support member 242 are for resting upon an underlying surface.

One or more wheel assemblies may be mounted to ends of one or both of the support members for rotation. For example, a first wheel assembly 250 and a second wheel assembly 252 may be mounted at opposing ends of the second support member 242. The wheel assemblies may be mounted to the second support member 242 to assist a user in moving the desk system 200. For example, when the desk system 200 is in the collapsed configuration, a user may grasp the first support member 240 to pull or push the desk system 200 while the wheel assemblies rotate upon an underlying surface. When the desk system 200 is in the expanded configuration, a user may grasp the seat 226 or other portion of the desk system 200 to orient the desk system 200 at an angle relative to an underlying surface and such that the only the wheel assemblies are contacting the underlying surface for desk system 200 movement. While the wheel assemblies are shown mounted to the second support member 242 in FIGS. 19 and 20, it is contemplated that the wheel assemblies may be mounted to the first support member 240 so that a user may grasp the second support member 242 to pull the desk system 200 along an underlying surface.

FIGS. 21 through 22b show further detail of the wheel assemblies. While FIGS. 21, 22a, and 22b refer to the first wheel assembly 250, it is to be understood that the second wheel assembly 252 may include similar components. The first wheel assembly 250 includes components arranged with one another to facilitate rotation of a wheel. For example, the first wheel assembly 250 includes a base component 260, a first intermediate component 262, a second intermediate component 264, a wheel 266, a third intermediate component 268, and a cap 270.

The base component 260 is sized for securing to one of the ends of the first support member 240 or the second support member 242. The first intermediate component 262 includes a through-hole sized for receiving a portion of the base component 260 for securing the first intermediate component 262 thereto. The second intermediate component 264 includes a base portion 272 for insertion within the through-hole of the first intermediate component 262 to secure the first intermediate component 262 and the second intermediate component 264 to one another. While shown as separate components in FIGS. 21 and 22a, it is contemplated that the first intermediate component 262 and the second intermediate component 264 may be formed as a single component.

The second intermediate component 264 may include flaps to assist in securement to the base component 260. For example, the second intermediate component 264 may include flaps 275 having a lip for gripping an edge of the base component 260 when the second intermediate component 264 is mounted to the base component 260. The second intermediate component 264 includes a first ledge 276 and the third intermediate component 268 includes a second ledge 278. When the second intermediate component 264 and the third intermediate component 268 are mounted to one another the first ledge 276 and the second ledge 278 are aligned to define a channel sized to receive a portion of the wheel 266.

FIG. 22b shows an example of a mechanical relationship between the wheel 266 and the third intermediate component 268. The wheel 266 may include a plurality of extensions 280 radially spaced about an inner surface of the wheel 266. A base portion 282 of the third intermediate component 268 includes a plurality of grooves 284 radially spaced about the base portion 282. The plurality of extensions 280 and the plurality of grooves 284 are sized for engagement to secure the wheel 266 and the third intermediate component 268 to one another.

The cap 270 may be fixed to the second intermediate component 264 such that the wheel 266 and the third intermediate component 268 may rotate. For example, the cap 270 may include cylinder-shaped mounts 286 for insertion within cylinder-shaped cavities of receivers 288 extending from the second intermediate component 264. In one example, the mounts 286 and the receivers 288 may be sized relative to one another to facilitate a snap-fit. In another example, the mounts 286 and the receivers 288 may have a non-cylindrical shape. The mounts 286 and the receivers 288 may be secured to one another via other methods, such as via an adhesive.

One or more rollers 290 may be mounted for rotation to the cap 270. For example, each of the one or more rollers 290 may be mounted about one of the mounts 286. The one or more rollers 290 extend into the channel when the cap 270 is mounted to the second intermediate component 264 to contact an inner surface of the third intermediate component 268 so that the third intermediate component 268 and the wheel 266 may rotate upon the one or more rollers 290.

FIGS. 23 and 24 show the desk top 206 of the desk system 200 in first and second positions. In FIG. 23, the desk top 206 is oriented in a landscape position. In FIG. 24, the desk top 206 is oriented in an easel position. A pivot assembly 294 assists in facilitating transition of the desk top 206 between the multiple positions such as the landscape position and the easel position. For example, the pivot assembly 294 may operate to adjust an angle of the desk top 206 relative to an underlying surface to provide multiple work surface options for a user.

The pivot assembly 294 is mounted to an inner column 308 of the column assembly 208. The inner column 308 may have a telescoping relationship with an outer column 310 of the column assembly 208 to raise and lower the desk top 206. A swivel mechanism may rotate the desk top 206 about an axis normal to the desk top 206.

FIGS. 25 and 26 show exploded views of portions of the desk system 200. The pivot assembly 294 may include a main component 320 and an adjustable lock mechanism 322 arranged with one another to facilitate adjustment of an angle of the desk top 206 relative to a user and relative to an underlying surface. An engagement mechanism 324 operates with the main component 320 to retain the desk top 206 in the landscape position or the easel position as further described below. A plate 326 is arranged with a lower surface of the desk top 206 to conceal a portion of the engagement mechanism 324 while providing access to an actuator to engage and disengage the engagement mechanism 324 with the desk top 206.

FIG. 27 is a detailed perspective view of the main component 320. The main component 320 includes a first extension 330 and a second extension 332. Each of the first extension 330 and the second extension 332 extend from a base portion 336. Each of the first extension 330 and the second extension 332 define an arcuate cutout 338. The arcuate cutout 338 may include a plurality of circular-shaped cutouts open to one another. The circular-shaped cutouts are sized to receive a pin of the lock mechanism 322. In one example, the arcuate cutout 338 may extend in an arc between zero and ninety-degrees relative to a center point of a circular portion of the first extension 330 and a center point of a circular portion of the second extension 332. The circular-shaped cutouts assist in providing various angled configurations for the desk top 206 relative to a user positioned on the seat 226 as further described herein. The number of angled configurations available is based on the number circular-shaped cutouts and the extension of the arcuate cutout 338.

The base portion 336 may define one or more openings 340 each extending in an arc of various degrees relative to a center point of the base portion 336. The one or more openings 340 provide space for fasteners to rotatably secure the main component 320 to the desk top 206. The main component 320 and the desk top 206 are arranged with one another so that the desk top 206 may rotate upon the main component 320 as guided by a relationship between the fasteners and the one or more openings 340. The base portion 336 may define one or more notches 342 spaced from one another to assist in facilitating engagement of the desk top 206 when rotated between positions. The base portion 336 may include cutouts to minimize a weight of material while also providing structural rigidity by having one or more tabs 344 radially spaced from one another.

FIGS. 28 and 29 show further detail of the main component 320 and the lock mechanism 322. The lock mechanism 322 may include a knob 350, a transfer assembly 352, a first slider 354, and a second slider 356. The knob 350 is mechanically linked to the transfer assembly 352 to direct rotation thereof. A first pin 358 is mounted to the first slider 354 and a second pin 360 is mounted to the second slider 356.

The transfer assembly 352 is mechanically linked to the first slider 354 and the second slider 356 to direct lateral translation of the sliders between multiple positions when the knob 350 rotates the transfer assembly 352. For example, the sliders may laterally translate to insert and retract the pins within the respective adjacent arcuate cutout 338 to facilitate transition between an engaged and a disengaged position of the pins. Each of the pins may include a spherical-shaped end to facilitate easier insertion and retraction of the pins within the arcuate cutout 338 in comparison to a cylinder-shaped end.

A spring 366 may be disposed between the first slider 354 and the second slider 356 to bias retention of the sliders toward the engaged position. Rotation of the knob 350 directs the sliders to translate in a direction opposite the bias of the spring 366.

FIGS. 30 and 31 are bottom plan views of a portion of the desk system 200 showing the desk top 206 in the landscape position and the easel position. In the landscape position as shown in FIG. 30 and the easel position shown in FIG. 31, the engagement mechanism 324 may engage with the main component 320. For example, the engagement mechanism 324 includes a T-knob 380 for engaging with the main component 320 via one of the notches 342. The T-knob 380 may include a handle for a user to pull the T-knob 380 out of the respective notch 342. Springs may be included within the engagement mechanism 324 to bias movement of the T-knob 380 toward engagement with the main component 320. Once the T-knob 380 is pulled out of the notch 342, the desk top 206 may be rotated for engagement with the other of the notches 342 to orient the desk top in either the landscape or the easel position.
