This application is a non-provisional of U.S. Provisional Application No. 61/639,667, filed Apr. 27, 2012, entitled “PANEL SLIDING HARDWARE SYSTEM”, which is hereby incorporated by reference.
This disclosure relates generally to enclosures, and more particularly, to systems for opening and closing panels of enclosures.
BACKGROUNDDisplay enclosures typically have one or more plates through which items in the enclosures can be viewed. In some cases, the plates may be adjusted or moved to access the interior of the enclosures. In such cases, the plates may be connected to a link system that allows for adjustment of the plate to one side of the enclosure or otherwise generally away from a side of the enclosure to be covered by the plate.
SUMMARYThis disclosure relates generally to enclosures, and more particularly, to systems for opening and closing panels of enclosures. In one illustrative instance, a panel sliding hardware system for use with a display case may include a mounting bracket, a first slide profile, a second slide profile and a slider, where the first slide profile is capable of rotating with respect to the mounting bracket and the second slide profile is capable of rotating with respect to the mounting bracket and linearly adjusting with respect to the mounting bracket. In some instances, the mounting bracket may connect to the display case and a first end portion of the first slide profile may connect to the mounting bracket. The slider may connect to the mounting bracket and the second end portion of the first slide profile to facilitate rotation of the first slide profile and the second slide profile with respect to the mounting bracket. To facilitate linearly adjusting the second slide profile with respect to the mounting bracket, the second slide profile may engage the first slide profile.
In another illustrative instance, a display case mounting system may include a mounting bracket, a first slide profile, a second slide profile and a slider, where connecting features of the first slide profile may engage connecting features of the second slide profile. In some instances, the mounting bracket may connect to the display case and the first slide profile may be adjustably connected to the mounting bracket. Illustratively, the slider may have a first end engaging the mounting bracket and a second end connected to the second end portion of the second slide profile.
In some instances, a method may be used to position a panel used with a display case between a closed position and an opened position. The method may include adjusting the panel about a rotating axis formed at a connection point between a hinge and a sliding panel mount connected to the panel. In some instances, the method may further include sliding the panel in a linear direction away from the rotating axis. Illustratively, the sliding panel mount may include a first slide profile and a second slide profile, where adjusting the panel about the rotating axis may include adjusting the first slide profile and the second slide profile about the rotation axis and the sliding the panel in a linear direction may include sliding the second slide profile in a linear direction with respect to the first slide profile.
The preceding summary is provided to facilitate an understanding of some of the features of the present disclosure and is not intended to be a full description. A full appreciation of the disclosure can be gained by taking the entire specification, claims, drawings, and abstract as a whole.

In many instances, the term “about” may be indicative as including numbers that are rounded to the nearest significant figure.
The recitation of numerical ranges by endpoints includes all numbers within that range (e.g., 1 to 5 includes 1, 1.5, 2, 2.75, 3, 3.80, 4, and 5).
Although some suitable dimensions, ranges and/or values pertaining to various components, features and/or specifications are disclosed, one of skill in the art, incited by the present disclosure, would understand desired dimensions, ranges and/or values may deviate from those expressly disclosed.
As used in this specification and the appended claims, the singular forms “a”, “an”, and “the” include plural referents unless the content clearly dictates otherwise. As used in this specification and the appended claims, the term “or” is generally employed in its sense including “and/or” unless the content clearly dictates otherwise.
The following detailed description should be read with reference to the drawings in which similar elements in different drawings are numbered the same. The detailed description and the drawings, which are not necessarily to scale, depict illustrative embodiments and are not intended to limit the scope of the claimed disclosure. The illustrative embodiments depicted are intended only as exemplary. Selected features of any illustrative embodiment may be incorporated into an additional embodiment unless clearly stated to the contrary.
Typical links 210 of known display case panel hardware systems 200 may move a panel 220 about one or more pivot points to create an access space for accessing an interior of a display case. As shown in
In some instances, typical display case panel hardware systems can generate a moment arm that is generally perpendicular to the display case when a panel in the display case panel hardware systems is moved from an opened to a closed position or from a closed position to an open position. Such moment arms can generate unacceptable bending moments on a mounting surface of the display case, where a moment is defined by force acting on a point multiplied by a perpendicular distance from the point to a feature. At the maximum value or other values of the moment, pressure applied to the panel in the display case panel hardware systems and/or pressure from the panel may cause one or more links of the display case panel hardware systems to bend and/or otherwise deform. Such bending and/or deformation can result in the display case panel hardware system failing to close or open properly and the greater the perpendicular distance the less force that is needed to cause bending and/or deformation.
The panel sliding hardware system 10, as described herein and shown in the
The present system includes an adjustable panel sliding hardware system 10 for a sheet, panel, cover or door of perhaps an enclosure or display case for refrigeration, merchandise, and the like. The terms sheet, panel, cover and door may be substituted for each other in the present specification. Other equivalent terms may be used.
The present disclosure includes the panel sliding hardware system 10 for a display case 12, as shown in
The panel sliding hardware system 10 described herein may create a limited bending moment on the display case 12 by facilitating the pivoting of one end of a panel 19 with respect to the hinge 18 (e.g., a fixed hinge) connected to or unitarily formed with the mounting bracket 46 that may support the slide mechanism or slider 15, slide profiles 24, the panel 19, and any other associated hardware. In some instances, the rotation about the hinge 18 may be facilitated with the slider link 16 (e.g., a pivoting slide-link) and/or the spring(s) 28 (e.g., a pneumatic spring, gas spring, or other spring) connected to the mounting bracket 46.
The mounting bracket 46, as shown in
In some instances, the openings 45 or other features of the mounting bracket 46 may receive one or more connectors or other features to facilitate locating and/or mounting features of the panel sliding hardware system 10 and/or to facilitate mounting the mounting bracket 46 to the display case 12. In one example, the mounting bracket 46 may include openings 45 that may received connectors for mounting the mounting bracket 46 to the display case 12, where the openings 45 may be positioned to the sides of where the slider plate 14 may be adjustably positioned when the panel 19 is in a second position 32b or third position 32a so as to provide support for any bending moment created by the panel 19 or forces acting on the panel 19. Similarly, other openings 45 in the mounting bracket 46 may be positioned to facilitate supporting loads on the panel sliding hardware system 10 regardless of the orientation thereof.
In some instances, the rotation about the hinge 18 may facilitate providing a clearance to allow the panel 19 to be adjusted and/or slid with respect to the display case 12 around adjacent display cases and/or panel sliding hardware systems 10 connected to adjacent display cases. In some examples, bearings 26 (e.g., plain bearings or other bearings) and/or symmetrical mount features of slide profiles 24 and/or the panel clamp 20 may support the panel 19 and allow the attached panel 19 to slide to side positions with respect to the display case 12. As discussed, such movement of the panel 19 with the panel sliding hardware system 10 may reduce a perpendicular distance of the panel 19 with respect to the display case 12 and thus, reduce the bending moment on the display case 12 when providing access to the interior 13 of the display case 12, as compared to typical display case sliding hardware systems.
Illustratively, the slider link 16 may provide support for vertical loads (e.g., a vertical direction may be substantially perpendicular to a sliding direction of the slider link 16), where the vertical loads on the panel sliding hardware system 10 may be slidingly adjusted or moved by the panel sliding hardware system 10 allowing only a single degree of freedom (e.g., in a sliding direction or more than a single degree freedom to account for manufacturing tolerances, etc.) for the slider plate 14, or two or more degrees of freedom for the slider plate 14, to which the slider link 16 may be pivotally attached. Vertical loads may include, but are not limited to, the mass of panel 19 or other loads adjustably connected to the slider link 16.
In operation and as depicted by the arrows shown in
In some instances, the hinge 18 may have a substantially planar end profile 44. The planar end profile 44 may facilitate using panel sliding hardware systems 10 on adjacent display cases 12, where the adjacent display cases 12 may be in close proximity to one another, may be unitarily formed (e.g., unitarily formed display cases 12 may be distinguished by having separate panels 19), and/or may abut one another. To facilitate connecting the panel sliding hardware system 10 to the display cases or a feature (e.g., mounting bracket 46 or other feature) connected to the display cases 12, the hinge 18 may include one or more connector insets 42. In one example, the connector insets 42 may allow a user to insert a screw driver or other tool between adjacent panel sliding hardware systems 10 to connect the hinge 18 to the display case 12 or a feature connected to the display case 12.
As shown in
The lock connector 38 may adjustably engage the lock edge 40. For example, the lock connector 38 may engage the lock edge 40 such that applying a force to a first end 38a of the lock connector 38 in a first direction may cause the lock connector 38 to pivot about its connection or extension from the first slide profile 24a and disengage the lock edge 40 by actuating a second end 38b of the lock connector 38 in a second direction. In some cases, the first direction and the second direction may be in opposite or substantially opposite directions.
The lock connector 38 may be made from any material through any manufacturing process. For example, the lock connector 38 may be made from two or more materials and a co-extrusion process or other process to form the lock connectors from the two or more materials. In one example, a first material may be a rigid material and a second material may be a resilient material. Illustratively, the first material may be utilized at or about the first end 38a of the lock connector 38 and the second material may be utilized at or about the second end 38b of the lock connector 38 to form a rigid flex end or first end 38a and a resilient locking end or second 38b.
In some instances, the panel sliding hardware system 10 may include a cover plate 54, as shown in
Once the lock connect 38 has been released from engagement with the lock edge 40, the slide profiles 24 may be adjusted away from the display case 12 such that the slider plate 14 slides along the mounting bracket 46 to a stop or to a distance of the spring 28, the slider link 16 pivots about the slider plate 14, and the slide profiles 24 pivot about the slider link 16 to adjust the slide profiles 24 and the panel 19 away from the display case 12. The first slide profile 24a may be adjusted a maximum of a perpendicular distance from the display case, where the perpendicular distance depends on the length of the slider link 16. In some cases, the length of the slider link 16 and thus, the perpendicular distance, may be determined so as to provide a clearance and allow the panel 19 be slid in front of an adjacent display case 12 utilizing the panel sliding hardware system 10 or any other hardware system. As discussed above, it is desirable to have small perpendicular distances of the panel 19 with respect to the display case 12 and as a result, it is desired to have a perpendicular distance only large enough to provide clearance for allowing the panel 19 to be slid in front of adjacent display cases 12.
The first end 15a of the slider 15 or the slider plate 14, as shown in
As shown in
As shown in
Illustratively, the connectors 34 and/or 36 may be tightened until the panel clamp 20 abuts the second slide profile 24b to apply a pinching or pressure fit on the panel 19 between the panel wedge 22 and the panel clamp 20 or the connectors 34, 36 may be tightened to create a pinching or pressure fit on the panel 19 between the second slide profile 24b, the panel wedge 22 and/or the panel clamp 20. In one example, the female connector 34 may be tightened to apply a pressure fit to the panel 19 between the panel clamp 20 (and/or the panel wedge 22) and the second slide profile 24b and the female connector 34 may be loosened to release the pressure fit and allow the positioning of the panel 19 to be adjusted.
Panel 19 may be positioned in one or more positions within the panel clamp 20 and the second slide profile 24b. In some instances the panel 19 may be positioned within the panel sliding hardware system in a single configuration, in two or more configurations, in three or more configurations, in four or more configurations, in five or more configurations, or other amount of configurations. For example, arranging the panel wedge 22 in different positions within the panel clamp 20, the panel 19 may be arranged in at least four different positions. In some instances, panels 19 having varying profiles may be used in different panel arrangements, as desired.
In some instances, the panel wedge 22 may be adjusted to two or more positions to position the panel 19 in various orientations, as shown in
The panel wedge 22 may take on any shape, as desired. In one example, the panel wedge 22 may be a right angle triangle, as shown in
Illustratively, the first slide profile 24a and the second slide profile 24b may be configured to engage one another and the first slide profile 24a may have a first end portion and a second end portion with the first end portion connected to the mounting bracket 46 (e.g., directly or through any other feature such as the hinge 18), as shown in the Figures. In some instances, the slide profiles 24 may include slide rails 25, as shown in
Each of the slide profiles 24 may be symmetric, identical and/or substantially identical (e.g., substantially identical may be mean identical except for manufacturing tolerances). In one example, each of the slide profiles 24 may have identical or substantially identical cross-sections. Each slide profile 24 may include a first slide rail 25a (e.g., a first connecting feature or a male slide rail) and a second slide rail 25b (e.g., a second connecting feature or a female slide rail), where the first slide rail 25a of the first slide profile 24a may be received by or otherwise engaged with the second slide rail 25b of the second slide profile 24b and the first slide rail 25a of the second slide profile 24b may be received by or otherwise engaged with the second slide rail 25b of the first slide profile 24a.
The slide profiles 24 may be formed in any manner. In one example, the one or more of the slide profiles 24 may be extruded. In some instances, the first slide profile 24a and the second slide profile 24b may be formed from the same extrusion mold or two or more substantially identical molds. Extruding the first slide profile 24a, the second slide profile 24b, and/or other slide profiles 24 from the same extrusion mold may ensure each part has similar manufacturing tolerance to better allow the slide profiles 24 to mate with one another. Alternatively, or in addition, one or more of the slide profiles 24 may be formed from other forming processes using a mold or other feature to form the slide profiles 24, as desired. Illustratively, features of the slide profiles 24 may reduce manufacturing allowances for inherent manufacturing tolerances due to the slide profiles 24 being extruded from the same or substantially identical molds.
To facilitate movement between the first slide profile 24a and the second slide profile 24b, a multiple bearing geometry may be utilized to support and/or slide the panel 19 from an initial or closed position (e.g., the first position 32a, see
In some instances, the space between the slide rails 25 may be concentric about one or more of the first slide rail 25a and the second slide rail 25b. The space between the slide rails 25 may provide a calculated load caring capability as the slide profiles 24 move into a cantilevered or open position. Accordingly, the thickness of the bearings 26 may be adjusted, as desired, for particular loads on the panel sliding hardware system 10.
The bearings 26 may be connected to the slide profiles 24 in any manner. As shown in
Illustratively, the bearings 26 may be made from any material, as desired. In some examples, including examples where the panel sliding hardware system 10 may be used in the food industry or other industries, the bearings 26 may be made from a non-hygroscopic material, a non-nylon material, polymeric material, a hydrophobic material, and/or any other material, as desired.
As shown in
In operation, a spring 65 or other mechanism may bias the stop member 62 in a stop position, as shown in
In operation, the panel sliding hardware system 10 may be used in a method 100 of positioning the panel 19 used with the display case 12 between a closed position and an opened position, as shown in the flow chart of
Illustratively, the position of the panel 19 may be adjusted from the opened position to the closed position by reversing method 100. For example, the panel 19 may be moved radially toward the rotating axis by moving the second slide profile 24b in a linear direction with respect to the first slide profile 24a toward the rotating axis. Once the panel 19 has been moved toward rotating axis, the first slide profile 24a and the second slide profile 24b may be adjusted (e.g., rotated) about the rotating axis toward the closed position.
Although method 100 has been described in a particular order and detail, it is contemplated that the method 100 may include further intermediary steps and the steps of the method 100 may be in other orders, as desired.
In the present specification, some of the matter may be of a hypothetical or prophetic nature although stated in another manner or tense.
Although the present system has been described with respect to at least one illustrative example, many variations and modifications will become apparent to those skilled in the art upon reading the specification. It is therefore the intention that the appended claims be interpreted as broadly as possible in view of the prior art to include all such variations and modifications. Accordingly, departure in form and detail may be made without departing from the scope and spirit of the present disclosure as described in the appended claims.
