Rotatable Shelf

Abstract

The invention relates to a rotatable shelf bottom that has a tablet function (1) and is composed of a shell which is rotatably mounted on the bottom side (5b) of a bottom part (5). The shell comprises a bottom part (5) and a frame (1a) which are positively glued together by means of an adhesive duct that is filled with an adhesive. A frame (1a) is substantially L-shaped, forms part of the bottom side (5) of the bottom part (5) at the outer edge, and is removably placed on the top side of horizontal furniture components (30) located inside or outside a furniture carcass.

Description

This invention relates to a rotating shelf for use with furniture. When removed from the furniture, the shelf can also serve as a tray. The rotating shelf has a shelf surface with a frame that follows the outside contour. The shape of this outer edge features a reduced overall height, and the shelf is mounted rotatably on the upper surface of horizontal furniture components that are located inside or outside of a furniture carcass.

A rotating shelf of the prior art is distinguished by the fact that the shelf surface has a frame that follows the outer contour. Together with the base plate, this frame constitutes the rotating shelf's actual total height. Such a frame supports the storage and sorting of household objects and prevents those objects from sliding off over the outer edge. In order to make it easier to put objects into and sort objects inside furniture carcasses that are not easily accessible (as is the case, for example, with corner cabinets), rotating shelves are able to rotate on a centric or eccentric axis.

With a conventional rotating-shelf design for a rotating (or “lazy-Susan”) shelf unit, a rotating shelf is installed with a vertical rotating-axis shaft that goes through the inside space of the furniture carcass. Such a shelf is always installed with a second rotating shelf or with several rotating shelves. A central rotating-axis shaft, or a rotating-axis shaft that has been moved to the edge on one side, is used as a holder for the rotating shelves that are to be installed. Such shafts enable the shelves to rotate around a centric or eccentric axis point.

Having a rotating-axis shaft mounted in the middle of a rotating shelf reduces the possibilities for placing items on the upper surface that a rotating shelf has available for storing objects. The rotating-axis shaft that is installed in the middle of the rotating shelf limits the size of objects to be stored to half of the shelf's diameter.

Having a rotating-axis shaft installed on the side edge of a rotating shelf requires the rotating shelf unit to be aligned in accordance with the interior geometry of the furniture carcass in order not to restrict the positioning of objects. Furthermore, the inside space of furniture carcasses are always equipped with a complete rotating-shelf unit, which does not permit the use of other furniture components, such as fixed or adjustable shelves. Consequently, employing rotating shelves is limited to furniture carcasses that have been designed for that purpose. In addition, the construction of a rotating shelf unit with the total height of the individual rotating shelves and the rotatable mounting takes up a correspondingly large amount of a furniture carcass's overall height. As a result, there is space for one less shelving level compared to the number of shelving levels available with adjustable shelves. A further disadvantage is that, with a rotating shelf that has a reduced diameter, the outer edge constitutes the total height of a revolving shelf. Consequently, there is a disparity in the proportions of the various parts in the embodiment of a rotating shelf.

The aim of the present invention is to create a rotating shelf that has an outer edge with a lower total height so that, with a revolving shelf with a reduced diameter, a more balanced relationship is achieved between the individual proportions in the overall visual effect. In addition, it is possible to mount an individual rotating shelf, such as a fixed or adjustable shelf, on the upper surface of horizontal furniture components. Furthermore, it is possible to do without the installation of a rotating-axis shaft that goes through the total height of a furniture carcass's interior space. This avoids the loss of vertical height while still allowing rotation around a centric or eccentric axis point.

This objective is accomplished according to the present invention by using a frame that essentially constitutes an L-shape and forms a portion of the upper surface of the base plate toward the middle of a rotating shelf. In this way, it is possible to move the base plate back a bit from the outside edge toward the middle. In addition, in a preferred embodiment, on the undersurface of the base plate of a rotating shelf, there is a cylindrical receptacle, which forms a centric or eccentric rotational axis, and round-shaped elements that are able to rotate and roll as cylindrical roller bearings, ball bearings or similar rolling elements in a circular track. This enables individually rotatable shelves to rotate on a horizontal furniture component.

In a preferred embodiment, a frame, which essentially constitutes an L-shape and forms a portion of the upper base plate surface, is made from a transparent or translucent plastic. A frame according to the present invention can be made through injection molding and also in part through a deep-drawing process. Additionally, it is possible in both processes to combine transparent sections with translucent sections. In this way, details required for the design, such as raised structures (bumps) that are formed as circumferential joints or nubs, can be realized translucently. This is done in order to prevent obvious minor damage caused by mechanical loads when objects that are to be stored generate impact.

It is also possible, however, for portions of the frame that is used to frame in the shelf upper surface to be translucent, and the portion that forms the section of the upper shelf surface to be transparent. As an alternative, these different types can be combined. In this way, it is possible to create the visual impression that the outer edge, which is translucent, is installed in a self-supporting manner. The combination of transparent and translucent surface sections can be realized on both sides, or on just one side. When on one side, it can be on the inside or outer area of a frame.

With a rotating shelf according to the present invention, a circumferential form recess is prepared in the frame to accommodate a base plate, which is formed with another circumferential indentation and with a bearing surface for a base plate. The circumferential indentation is for receiving a bonding agent. In addition, there is an additional recess in the leading edge of a base plate, which is located circumferentially between two contact surfaces. Another recess that is used in a frame's form recess creates a bonding-agent channel into which a bonding agent is fed in through an opening. This is done in order to bond a base plate to a frame. Moreover, a rotating shelf can be made completely of plastic. In such cases, instead of inserting a base plate, a translucent section is formed. Rotation is made possible by means of a plurality of round-shaped elements, cylindrical rollers and bearings or similar rolling elements, which are retained together in a housing and in a round or ring-shaped apparatus with a corresponding recess, or as individual axially rotatable rolling elements around a centric or eccentric rotational axis, which are—in a preferred embodiment—mounted on the undersurface of a rotating shelf. Depending on the requirements, a centric or eccentric rotational-axis point is realized in the form of a removable cylindrical pin or a cylinder that is partially shouldered on one end, which is permanently inserted into a horizontal furniture component and serves as a receptacle for a rotating shelf.

For both versions, a recess is required on the upper side of a horizontal furniture component. If one wants to do without a recess in a horizontal furniture component, a cylindrical receptacle can be bonded to the upper surface of a furniture component.

A rotating shelf according to the present invention with a reduced outer edge and a rotatable mounting makes it possible to use a rotatable shelf in additional ways. In this case, it is enough to have a horizontal furniture component that is installed inside or outside the furniture carcass. Suitable furniture components could be fixed or adjustable shelves that are installed in a furniture carcass. Outside a furniture system, it is possible, for instance, to use open shelves and individual (“stand-alone”) shelves for the use of a rotating shelf. Since adjustable shelves are usually employed in furniture carcasses, with some types of cabinets, it is not possible to use prior-art hardware fittings in some specific cases to make it possible to simplify the sorting and placement of objects to be stored. With a rotating shelf according to the present invention, simple mounting and retrofitting in a selected section of the furniture carcass is possible. For example, this could be done in a hung wall cabinet for kitchen use. Such cabinets generally have little cabinet depth, and they are divided into shelving modules in which different objects can be put inside in an unsorted fashion one behind the other or one next to the other. When a person is searching for a specific object inside, the objects in the shelving module are moved back and forth or taken out of the shelving module.

With a rotating shelf according to the present invention, it is possible to keep diverse objects of different kinds together and to roll them through the full cabinet depth. This keeps objects of different kinds accessible in a simple way.

Further features of the invention are the object of additional subclaims.

In FIG. 14, a cross-sectional contour of frame 1a is shown essentially in the form of an unequal angular shape.

In FIGS. 15 to 18, bearing surfaces 1e in a leading edge are enclosed in connection with a closed bonding-agent channel.

FIG. 24 shows a rotation-symmetric sectional view of rotating shelf 1, which can serve as a tray, according to the present invention, in the form of a plastic shell.

FIG. 1 shows a rotating shelf 1 according to the present invention. Rotating shelf 1 can also serve as a tray, and it comprises a shell with rotatable mounting on the undersurface of a base plate 5. The shell comprises base plate 5 and a frame 1a, which are bonded together in interlocking fashion by means of a bonding-agent channel filled with a bonding agent. In accordance with a rotatable mounting, frame 1a is equipped with an additional function, with a radially circumferential edge bracket or an edge bracket 7 formed in a plurality of sections, or a circular track as in FIG. 19. The edge bracket holds a disk-shaped device 8 in the correct direction and shape when receiving a rotating shelf from a horizontal furniture component on a base-plate undersurface 5b. Disk-shaped device 8 has, at a centrical midpoint, a circular recess 8a for a round mount 12. Circumferentially around recess 8a, opposite a bearing surface 8c, a shoulder 8b is inserted into a cylindrical shape so that, in mounting position, round mount 12 essentially forms one surface plane with bearing surface 8c. On the outer edge is, in the form of a U-shape, a recess 8d, which forms a circular track 15a, in which a plurality of rolling elements 9 in a holder 10 are arranged radially and mounted. On the side walls of the circular track, the holder enables guidance by means of gliding friction. On frame 1a there is, on base-plate undersurface 5b, essentially an angle shape that forms a collar which is, at a distance, arranged in parallel with base-plate undersurface 5b, and engages in the middle of the free space of a joint form 7a, overlapping to the inside.

A disk 11, which rests against base-plate undersurface 5b, realizes a circular track 15a. Through recess 8a, with round mount 12, disk-shaped device 8 and disk 11 on base-plate undersurface 5b are mounted by means of a screw connection. Disk-shaped device 8 is comprised, in the entire embodiment, essentially of a formed flat stock.

Round mount 12 in FIG. 2 is fitted to base-plate undersurface 5b, with a circular folded recess 12a, in which disk-shaped device 8, with recess 8a, fits closely and is held in place, and it is mounted on base-plate undersurface 5b through recess 12c by means of a screw connection. A centrical recess 12b runs the full depth with a bore diameter that is suited to receive a cylindrical pin 13, as in FIG. 3, with a loose fit. Another cylindrical recess 12e has a diameter larger than that of recess 12b and reaches approximately half the height of round mount 12. Consequently, two different receptacles, one on top of the other, are created for cylindrical shapes in the direction of a furniture component 30. FIGS. 3 and 4 show a bushing 14 at a corresponding position, where cylindrical pin 13 is inserted, which allows for the receiving of rotating shelf 1 in recess 12b. A single flat washer 18a, as shown in FIG. 5, can be screw-mounted or bond-mounted onto furniture component 30, as shown in FIG. 7, by means of a bonding agent 18c, or by means of a recess 12c as shown in FIG. 6.

Cylindrical pin 13 and/or a shouldered cylindrical pin 18 or flat washers 18a enclosed in round mount 12 form a centric or eccentric axial point 30c. Instead of axial point 30c, the corresponding receptacles, 13, 18, and 18a, can also serve as at least two of a plurality of installation points 30d at a distance from one another. Installation points 30d are adjacent to an inside member 30e or outside member 30f of a formed sleeve bearing 15 or disk-shaped device 8 and make it possible to place a rotating shelf 1 in accordance with a specific position. In addition, a third installation point 30d, or several installation points 30d, can further simplify positioning.

FIG. 8 shows a partial sectional view of the outer edge of rotating shelf 1, according to the present invention, in which base plate 5 is made of a wooden board material. Frame 1a is fitted circumferentially on the outer edge following the circumferential contour of base plate 5. The cross section of frame 1a is formed by an unequal angle, which essentially has an L-shape and is, in a preferred embodiment, made of transparent plastic.

The smaller side piece of the L-shaped unequal angle is a surface section 1b of frame 1a. Surface section 1b circumferentially forms a portion of the surface plane around the outer edge analogous to a base-plate upper surface 5a. The perpendicular positioning of an L-shape of a wall element 1c of frame 1a with respect to base-plate upper surface 5a and surface section 1b creates a space for a shell shape that is open to one side. Surface section 1b of frame 1a is, at the point of connection to the leading edge of base plate 5, equipped with a circumferential elevation 2 (bump) that projects above the entire surface plane of base-plate upper surface 5a and surface section 1b on the surface by an amount that matches a size requirement, and acts as a border.

Protruding from elevation 2 is an additional circumferential formation 1d of frame 1a, which frames in a leading edge 5c of base plate 5 in a cross-sectional contour that tapers toward the middle of the plate for base-plate undersurface 5b. Formation 1d is fitted with an additional form recess 4 that protrudes toward base-plate undersurface 5b and realizes a portion of, or all of, a bonding-agent channel and engages in an interlocking fashion into base-plate undersurface 5b and serves as a bearing surface 1e for base plate 5. The diameter of the perimeter of bearing surface 1e is always smaller than base plate 5. At bearing surface 1e, a collar 7 is formed radially circumferentially, or in sections, toward an axis of rotation. In a preferred embodiment, collar 7 has the form of folded joint, and it is at a distance from, but in parallel with, base-plate undersurface 5a. Together with inserted base plate 5, collar 7 creates a gap in the form of a groove.

On circumferential leading edge 5c of base plate 5, at a distance between two separated contact surfaces, a contact surface 4a and a contact surface 4b, there is recess 5d. Recess 5d forms a bonding-agent channel or a portion thereof. Contact surface 4a protrudes from base-plate upper surface 5a and leading edge 5c and is formed with a bearing surface that is as small as possible. Contact surface 4b is at base-plate undersurface 5b and abuts bearing surface 1e. Contact surface 4a and 4b, which abut the inside of a cross-sectional contour that tapers on the inside of form recess 1d of frame 1a, create a circumferential closed cavity that is a bonding-agent channel. The bonding-agent channel has at least two axially symmetrical openings across from each other: an inlet opening 1f for the bonding agent and air outlet opening 1f. Openings 1f are built in with the largest possible distance to base-plate undersurface 5b in overlapping recess 4. Via inlet opening 1f, a free-flowing bonding agent 3 is added under slight pressure. The air escapes via at least a second opening, air outlet opening 1f.

In this way, a circumferential bond is created between base plate 5 and frame 1a. This makes it possible to create a permanent bond between the frame 1a and base plate 5. With frame 1a which, in a preferred embodiment, features transparent plastic, the bonding agent can optionally be chosen in different colors or in small granulate particles and/or particles and thus offer a corresponding color design.

FIGS. 9 and 10 show a partial sectional view of frame 1a, which is similar to the one in FIG. 8, with the exception of the perpendicular positioning of the L-shape for section is of frame 1a. The shell edge of section 1c, which is open on one side, is slanted outward from the center beyond the outer edge of section 1b. As an alternative, in an arrangement similar to FIG. 9, it has, as shown in FIG. 10, a convex curve across the length of section 1c.

FIG. 11 shows an embodiment of base plate 5, comprising two individual boards in a layered mounting position, beginning from base board 5e, which supplies base-plate undersurface 5b and leaves a free space to base-plate upper surface 5a. In this free space, it is possible to insert an additional plate 5c that features a correspondingly high surface quality, such as, for example, a glass plate. On its undersurface, the glass plate has a coating in the form of paint or of a film made of metals or plastics. In a preferred embodiment, the base plate is made out of a wooden board material and fitted with circumferential leading-edge recesses 5b shown in FIG. 8. Also in FIG. 11 is the form recess 1d with the partial recess of the recess form 4, which instead of being at a slant as in FIGS. 8 to 10, is rounded to the outside.

Bearing surface 1e ends on base-plate undersurface 5b. This creates free installation space for an additional rotatable mounting, which is mounted radially from an axial point and runs circumferentially on the outer edge of base-plate undersurface 5b. This also realizes a feature for a shell or a tray that is not equipped with a rotatable mounting.

FIGS. 12 and 13 shows two cross-sectional contours in different dimensions for frame 1a, which are employed individually or together in a shell, either as a whole or in a plurality of sections. In FIG. 12, a length B of surface section 1b is very short or equal to zero, and in FIG. 13, length B is disproportionately long in comparison to a length A of wall element 1c. In accordance with different form requirements with respect to functional or aesthetic considerations, two different forms or geometric shapes in convex or non-convex surface shapes can be implemented in a shell. In the periphery around frame 1a following the outer contour of base plate 5, length B of surface section 1d, which measured from the lower outer edge of frame 1a to the leading edge of base plate 5, lengthens to accommodate a shape until a turning point that is dictated by the shape is reached. Then length B shortens again and/or runs in sections of frame 1a essentially in parallel with base plate 5. The cross sections shown in FIGS. 12 and 13 can also be fashioned using further dimensions in between these values for the unequal angle of an L-shape in frame 1a all the way around or in sections.

FIG. 14 shows a cross-sectional contour of frame 1a with an additional feature. Frame 1a has wall element 1c, and adjacent to that, form recess 1d, which follows an outer wall of the perimeter contour of base plate 5 in a straight construction. Adjacent to the framing of leading edge 5c of base plate 5 through form recess 1d, bearing surface 1e for a base plate 5 overlaps directly on base-plate undersurface 5b and ends in interlocking form. The bonding-agent channel is only formed through recess 5d between contact surfaces 4a and 4b at leading edge 5c of base plate 5.

FIG. 15 shows how bearing surface 1e at form recess 1d engages with leading edge 5c from base plate 5 in a recess provided for this purpose. There, bearing surface 1e is essentially mounted in interlocking fashion with the surface of base-plate undersurface 5b. Inlet opening 1f is integrated on the undersurface of base plate 5 at a slant. In FIG. 16, bearing surface 1e is formed at surface section 1b and is essentially mounted in interlocking fashion with base-plate upper surface 5a, and it engages into leading edge 5c of base plate 5 as in FIG. 15.

FIGS. 17 and 18 show embodiments in which bonding-agent channel 4c is open to one side, in one case toward the upper surface and in one case toward the undersurface of base plate 5.

In FIG. 17, bearing surface 1e is formed toward base-plate upper surface 5a at surface section 1b as shown in FIG. 16, with base plate 5 in an adjacent position. Leading edge 5c is set back a bit circumferentially in the area of form recess 1d, and toward base-plate undersurface 5b, and it offers a groove-shaped space for a bonding-agent channel 4c that is open on one side and is filled with bonding agent.

FIG. 18 shows bearing surface 1e just as it is in FIG. 15, and shows base plate 5 with bonding-agent channel 4c that is open to one side and filled with bonding agent as in FIG. 17. However, the opening is directed toward base-plate upper surface 5a in this embodiment.

FIG. 19 shows how, at bearing surface 1e, with a lengthening of the surface, circular track 15a is formed radially around axial point 30c. Circular track 15a has two guiding walls that are at a distance from one another and positioned at a right angles to circular track 15a. These guiding walls are, in sections or at points, fitted with a formed retaining clamp 1i. Ring-type circular track 15 with a U-shape is fitted with a retaining collar 15c, which is directed toward circular track 15a at both ends of the U-shape. With regard to their mounting position and their position to each other, retaining clamp 1i and retaining collar 15d interlock with the limited free spaces which are open to one side in their cross-section in this way. Inside circular track 15a, with guiding walls and retaining clamp 15d, are rolling elements in accordance with FIG. 19. In addition, U-shaped ring-type circular track 15, in the area of circular track 15a, is provided with a corresponding double-sided guiding recess 15b that penetrates the full depth. The operating clearance of the guiding recess 15b and of the slide way of mount 10 is dimensioned so that the clearance between retaining clamp 15c and retaining clamp 15d does not allow any contact during operation.

In FIG. 20, ring-shaped circular track 15a is mounted centrically at the outer edge around axial point 30 on base-plate undersurface 5b near the end of the bearing surface 1e. Positioned opposite circular track 11a is U-shaped, ring-type circular track 15 with a circular track 15a on the inside and a circumferentially formed collar 15d above the U-shape on one side. In the mounting position, collar 15d leaves a clearance toward base plate undersurface 5b. Lying inside the U-shape are rolling elements 9 in a mount 10, which are radially arranged around axial point 30c. Mount 10 is essentially located opposite the U-shape on the inside of that shape, circumferentially or in sections, in the area of rolling elements 9. Rolling elements 9 are guided through sliding friction using an axial value. An edge bracket 16 is, at points or in sections, mounted using a radial value in parallel with ring-type circular track 15 in a sliding contact 16a on base-plate undersurface 5b. In a preferred embodiment, this mounting is accomplished with a screw connection. On its freely protruding end, edge bracket 16 is fitted with an overlapping formation opposite the basic surface which, via the outer edge of collar 15d, engages with clearance in the direction of ring-type circular track 15. Edge bracket 16 keeps ring-type circular track 15 in the desired direction and shape when receiving furniture component 30.

In FIG. 21, base plate 5 is an assembly 5f which, in a preferred embodiment, would be made out of an injection-molded plastic piece. In such an embodiment, base plate 5 is designed so that leading edge 5c is formed to correspond to the inside of a cross-sectional contour of form recess 1d. In addition, a receptacle recess 5e is built into base-plate undersurface 5b. On bearing surface 1e of frame 1a, a lamella shape 1g is formed in sections or circumferentially toward base-plate upper surface 5a. Together with form recess 1d, lamella shape 1g sets the limits, toward base-plate upper surface 5a, for a space that is open to one side. Into this space, base plate 5 engages with leading edge 5e. With receiving recess 5e and lamella shape 1g, frame 1a interlocks with base plate 5 and is retained positively.

At frame 1a in FIG. 22 and FIG. 23, lamella shape 1g is attached at surface section 1b toward base-plate undersurface 5b. Lamella shape 1g engages into a receptacle recess 5e, which is on base-plate upper surface 5a at a distance from the leading edge and, set back somewhat, it engages toward the middle of the base plate.

In this embodiment, base plate 5 has a recess on base-plate upper surface 5a. This recess begins at receptacle recess 5e and continues toward leading edge 5c and has a thickness that matches the cross section of surface section 1b. In FIG. 22, leading edge 5c has, in this case, the shape and form of an interlocking formation in accordance with the requirements of a visible edge. At frame 1a in FIG. 23, form recess 1d interlocks in a straight line in front of leading edge 5c of assembly 5f.

FIG. 24 shows rotating shelf 1 according to the present invention with frame 1a and base plate 5 formed as a single piece in a plastic shell. In a preferred embodiment, frame 1a with surface section 1b and wall element 1c is made of a transparent plastic. Base plate 5 is translucent. In a preferred embodiment, translucent base plate 5 is realized through a surface structure on base-plate upper surface 5a and/or base-plate undersurface 5b. A further possibility would be to use a plastic injection molding process to put a thin plastic coating in the area of base plate 5.

Base plate 5 can also, through use of a thin film, be formed from a board material or an assembly.

A surface recess is formed in the plastic shell in the area of base plate 5 to match the cross-sectional thickness of a film, a board material, or an assembly. A corresponding film, board material, or assembly is inserted into this surface recess and, analogous with surface section 1b, creates a level basic surface in a plastic shell.

Furthermore, to enable rotatable mounting, circular track 15a is formed in accordance with FIG. 20 on undersurface 5b of the plastic shell's base plate 5.
