DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0046] Referring now to the figures, wherein like reference numerals represent like parts throughout the several views, exemplary embodiments of the present disclosure will be described in detail. Throughout this description, various components may be identified having specific values, these values are provided as exemplary embodiments and should not be limiting of various concepts of the present invention as many comparable sizes and/or values may be implemented.

[0047] FIG. 1 depicts the inventive desktop apparatus 20 positioned in a corner of a modular business cubicle (MBC) by way of example only; the apparatus 20 can be used with any type of cubicle having tiles or segments, as will be apparent from the detailed discussion below. FIG. 26 depicts the inventive desktop apparatus 20 positioned on a wall of the cubicle but not adjacent a corner of the cubicle MBC. Thus, FIGS. 2-25 discuss the desktop apparatus 20 being installed within the corner of the cubicle MBC. The desktop apparatus 20 being installed completely along a wall of the cubicle MBC, with the understanding that the left side supporting bracket 124 in FIG. 26 is a mirror structure of the right side support bracket 26 but the releasable locking mechanism works the same.

[0048] As mentioned above, FIG. 1 depicts the inventive desktop apparatus 20 positioned in the corner but with a desktop element 22 not yet locked in place. As can be seen most clearly in FIG. 3, the desktop apparatus 20 comprises the desktop element 22 having a left side 22F and a right side 22G. Both of these sides are positioned on support brackets 24 and 26 that are releasably coupled to cubicle walls CW1 and CW2, respectively. The left-side support bracket (LSSB) 24 is releasably coupled to cubicle wall CW1 and the right-side support bracket (RSSB) 26 is releasably coupled to cubicle wall CW2, the details of which are discussed later.

[0049] As shown most clearly in FIGS. 22-25, the desktop element 22 comprises a top side 22A and a bottom side 22B, a left side 22F and a right side 22G. As shown most clearly in FIGS. 23-24, receptacle brackets 100A and 100B are installed on opposite sides of the bottom side 22B. Liner grooves 22C and 22D are formed into the bottom surface 22B, along the respective sides 22F/22G of the desktop element 22. An adhesive 102A and 102B is applied inside the respective grooves 22C/22D. The receptacle brackets 100A/100B are then fixedly pressed and secured inside the grooves so that the receptable brackets 100A/100B form a smooth contour with the bottom surface 22B. Each receptacle bracket 100A/100B comprises a plurality (e.g., five) serially-aligned chambers, CH1, CH2, CH3, CH4 and CH5. Chambers CH1-CH4 are configured to receive respective L-shaped projections P1, P2, P3 and P4 of the brackets 24/26, as shown most clearly in FIG. 20. Chamber CH5 in each receptacle bracket 100A/100B contains a respective release device 104A and 104B, as discussed next.

[0050] Each release device 104A/104B comprises a small leaf spring in a V-shape having a corresponding release button 106A/106B on one end of the leaf spring. FIG. 21 depicts release device 104B positioned in chamber CH 5 of receptacle bracket 100B (it being understood that the same goes for the release device 104A in chamber CH5 of the other receptacle bracket 100A). One portion of the -shaped leaf spring 104B1 is secured to an upper wall of the fifth chamber CH5, while the other portion of the V-shaped leaf spring 104B1 having the release button 106B thereon is free to move up and down (similarly, the same goes for the release device 104A, shown in FIG. 25). FIG. 25 is cross-sectional view of the left receptacle bracket 100A, showing the five chambers CH1-CH5, along with the release device 104A secured inside chamber CH5.

[0051] The following discussion relates to the left-side support bracket (LSSB) 24 and the right-side support bracket (RSSB) 26.

[0052] As shown most clearly in FIGS. 3-4, the LSSB 24 comprises a horizontal flange 24A and a vertical flange 24B. The horizontal flange 24A comprises an extension 24A1 with an aperture 24A2. Vertical flange 24B comprises a plurality of apertures to receive fasteners (e.g., screws) therethrough for securing the LSSB 24 to the cubicle wall CW1. The top side of the horizontal flange 24A comprises a plurality (e.g., four) L-shaped projections P1-P4 (see FIG. 8) which are configured to fit into the corresponding chambers CH1-CH4 in receptacle bracket 100A.

[0053] With the left-side 22F of desktop element 22 is positioned over the LSSB 24 and the projections P1-P4 inserted into the respective chambers CH1-CH4, when the desktop element 22 is slid back (away from the wall CW2, towards the installer), the release button 106A slides over the extension 24A1. As the sliding motion continues, the release button 106A finally seats itself into the aperture 24A2, thereby releasably locking that side of the desktop element 22 into the LSSB 24.

[0054] The details of the RSSB 26 are shown in FIGS. 5-6. The bracket 26 also comprises a horizontal flange 26A and a vertical flange 26B. In addition, since the RSSB 26 is positioned at the open right side 22G of the desktop element 22, the RSSB 24 forms a cantilever bracket in that the RSSB 24 is attached only at one end to the cubicle wall CW2. The releasable securement of the RSSB 26 to the cubicle wall CW2 is implemented via a perpendicular forward portion comprising an upper vertical flange 26C and a lower vertical flange 26D. Upper vertical flange 26C downwardly depends from the horizontal flange 26A whereas lower vertical flange 26D is a perpendicular extension of the vertical flange 26B. As with the LSSB 24, the horizontal flange 26A comprises an extension 26A1 with an aperture 26A2. When the right-side 22G of desktop element 22 is positioned over the RSSB 26 and the projections P1-P4 inserted into the respective chambers CH1-CH4, when the desktop element 22 is slid back (away from the wall CW2, towards the installer), the release button 106B slides over the extension 26A1. As the sliding motion continues, the release button 106B finally seats itself into the aperture 24A2, thereby releasably locking that side of the desktop element 22 into the RSSB 26.

[0055] The following discussion is related to releasably mounting the LSSB 24 and the RSSB 26 to respective cubicle walls CW1 and CW2 that form a corner (again, by way of example only) in the modular business cubicle MBC.

[0056] As shown most clearly in FIG. 7, a C-shaped mounting bracket 28 is used to secure the LSSB 24. In particular, the C-shaped mounting bracket 28 has a lip 28A (FIG. 8) that is inserted in between two vertically-connected tiles T1/T2. With that lip 28A trapped between the two tiles T1/T2, the C-shaped mounting bracket 28 provides a standoff surface 28B for receiving fasteners F (e.g., screws) therethrough. As shown in FIG. 8, the standoff surface 28B comprises a plurality of apertures A. When the LSSB 24 is to be secured to the cubicle wall CW1, oval-shaped apertures OA in the vertical flange 24B are aligned with the bracket apertures A and the fasteners F secured therein. The oval-shaped apertures OA allow for horizontal adjustment of the LSSB 24.

[0057] As shown most clearly in FIG. 9, a shorter C-shaped mounting bracket 29 is used to secure the RSSB 26. In particular, the C-shaped mounting bracket 29 also has a lip 29A (FIG. 10) that is inserted in between two vertically-connected tiles T3/T4. With that lip 29A trapped between the two tiles T3/T4, the C-shaped mounting bracket 29 also provides a standoff surface 29B for receiving fasteners F (e.g., screws) therethrough. As shown in FIG. 10, the standoff surface 29B comprises a plurality of apertures A. When the RSSB 26 is to be secured to the cubicle wall CW2, oval-shaped apertures OA in the upper vertical flange 26C are aligned with the bracket apertures A and the fasteners F secured therein. The oval-shaped apertures OA allow for horizontal adjustment of the RSSB 26. Furthermore, the lower vertical flange 26D acts to transfer the loading applied to the desktop element 22 on the right side thereof to the cubicle wall CW2.

[0058] To releasably secure the desktop element 22 to the LSSB 24 and the RSSB 26 once those two brackets are secured to the cubicle walls CW1 and CW2, the user/operator will position the bottom side 22B of the desktop element 22 over the two brackets 24/26 with the forward end 22E of the desktop element 22 up against the cubicle wall CW2, as shown in FIGS. 15-21. With the forward end 22E of the desktop element 22 against the cubicle wall CW2, the user/operator will seat all of the L-shaped prongs P1-P4 of both brackets 24/26 into corresponding chambers CH1-CH4 of the receptacle brackets 100A/100B in the bottom side 22B of the desktop element 22. At that point, the release buttons 106A/106B are compressed upward since the extensions 24A1 and 26A1 are compressing the release devices 104A/104B in the receptacle brackets 100A/100B. The user/operator then pulls back on the desktop element 22, thereby moving the forward edge 22E away from the cubicle wall CW2 and this backward movement causes the release buttons 106A/106B to seat themselves in the respective apertures 24A2/26A2 of the cantilever brackets 24/26, thereby releasably securing the desktop element 22 on the two support brackets 24/26. In doing so, a gap G is created between the forward edge 22E of the desktop element 22 and the cubicle wall CW2, as shown in FIGS. 2-3 and 11-14. An elongated tray (not shown) can be inserted into the gap G to prevent writing implements or other items from falling over the forward edge 22E and onto the floor.

[0059] Conversely, to disengage the desktop element 22 from the two support brackets 24/25, the user would depress the release buttons 106A/106B upward and then slide the desktop element 22 forward (so that forward edge 22E contacts wall CW2) and then lift the desktop element 22 upward to disengage the desktop element 22 from the support brackets 24/26.

[0060] FIG. 26 depicts the desktop apparatus 20 releasably mounted on a cubicle wall (formed by two serial cubicle walls CW2 and CW3). Since there is no corner in this mounting, the left-side support bracket requires a cantilever structure, similar to RSSB 26. As such, the left-side support bracket 124 is a mirror structure of RSSB 26 but for use on the left side 22F of the desktop element 22. In particular LSSB 124 comprises a horizontal flange 124A and a vertical flange 124B. In addition, since the left side 22F of the desktop element 22 is now also open, releasable securement of the cantilever LSSB 124 is implemented vial a perpendicular forward portion comprising an upper vertical flange 124C and a lower vertical flange 124D. Although not clearly shown, a C-shaped mounting bracket, having an upper lip and standoff surface, similar to the C-shaped mounting bracket 29 used with the RSSB 26, is used along with fasteners to releasably couple the LSSB 124 to the cubicle wall.

[0061] It should be further noted that if the desktop element 22 were to be releasably positioned in the modular cubicle MBC such that the right side 22G of the desktop element 22 were located in a cubicle corner, then a mirror bracket of LSSB 24 would be used to engage with receptacle bracket 100B to releasably secure the right side 22G within that cubicle corner and the LSSB 124 would be used to engage with receptacle bracket 100A to releasably secure the left side 22F of the desktop element 22 at that corner of the cubicle MBC.

Releasably-Locked Furniture

[0062] It is also desirable to use the releasable locking mechanism (RLM) of the releasable desktop in furniture in general (and also referred to as furniture piece) to make their assembly, and dis-assembly, easier and more efficient. Thus, by way example the releasable locking mechanism can be used with conference tables, desks, desking systems (i.e., where multiple desks attach together with dividers to create a shared workspace), workbenches, coffee tables, end tables, caf tables (e.g., lunch tables), training tables, reception desks, etc.

[0063] To that end, FIGS. 27-29, depict a cabinet-style furniture 200, by way of example only, to disclose the application of the releasable locking mechanism (RLM) 202. This is by way of example only and is not meant to limit the use of the RLM 202 to that specific type of furniture. The important feature is the ability to releasably secure furniture parts together using the RLM 202.

[0064] As can be seen in FIG. 27, the furniture 200 comprises a pair of sidewalls 204 and 206 and having a top panel 208 and a base panel 210. The top and bottom edges of both panels 204/206 comprise the plurality of projections P1-P5 which are serially-aligned. As with the original invention 20, the present invention RLM 202 is not limited to five projections P1-P5; rather the number of projections is by way of example only. Consequently, there is a corresponding receptacle bracket 212 (which is very similar to the receptacle brackets (100A/100B) in the prior invention 20) on the corresponding edges of the inward-facing sides 208A and 210A of the top panel 208 and the bottom panel 210, respectively. Thus, as can be seen most clearly in FIG. 28, chambers CH1-CH5, also serially-aligned, are present in the receptacle bracket 212. And as mentioned previously with regard to receptacle brackets 100A/100B, the receptacle bracket 212 is fixedly pressed and secured inside a groove (not shown) so that the receptacle bracket 212 forms a smooth contour with the bottom surfaces 208A/210A.

[0065] As with the invention 20, the present invention of the RLM 202 also has a release device 214 (FIG. 29) that is located within an additional chamber, namely, a sixth chamber, CH6. The release device 214 comprises a small V-shaped leaf spring 214A with a release button 214B on one end of the V-shaped leaf spring 214A; and this entire release device 214 is positioned within chamber CH6 (FIG. 28). There is also a protuberance 215 (FIG. 29) located inside chamber CH6; the other end of the V-shaped leaf spring 214A (i.e., the side of the spring 214A without the release button 214B is secured (e.g., via an adhesive, fastener, etc.) to the top of this protuberance 215. However, since there are no support brackets as there were in the invention 20, a small cavity 216 (FIGS. 29 and 30) is formed in the edge where the corresponding projections P1-P5 are located, namely after projection P5 (see FIG. 27). As with the release devices 104A/104B, the leg of the V-shaped leaf spring 214A with the release button 214B thereon is biased away from the chamber CH6 and thus can freely move (e.g., in/out, up/down, etc.)

[0066] It should be noted that the orientation of the projections P1-P5 on the top of sidewalls 204/206 and the bottom sidewalls 204/206 are reversed. This is done to connect the sidewalls 204/206 to either the top panel 208 first and then the base panel 210 second, or vice versa. Thus, by way of example only, if the sidewalls 204/206 are to be releasably secured to the base panel 210 first, the projections P1-P5 on the bottom edges of sidewalls 204/206 are first inserted into their corresponding chambers CH1-CH5 of the corresponding receptacle bracket 212 in the base panel 210. FIG. 28 depicts the bottom edge of the sidewall 206 and one edge of the base panel 210. In particular, the projections P1-P5 are inserted into the corresponding channels CH1-CH5 and then the sidewall 206 is slid in the direction 220 or the base panel 210 is slid in the direction 218. Either way, during this sliding step, the release button 214B remains compressed inward within chamber CH6, against the bias of the V-shaped leaf spring 214A. As the sidewall 204 or 206 continues to slide in the direction 220, or the base panel 210 slide in the direction 218, (see FIGS. 27-28) the projections P1-P5 slide fully into their corresponding chambers CH1-CH5, and the release button 214B will seat itself into the cavity 216 due to the bias of the V-shaped leaf spring 214A, thereby halting any further relative movement of these furniture components and releasably locking the sidewalls 204 and 206 to the base panel 210.

[0067] As similar process is carried out for attaching the top edges of the sidewalls 204/206 to the top panel 208. The only difference is that because the orientation of the projections P1-P5 and the corresponding channels CH1-CH5 in the receptacle brackets 212 in the top panel surface 208A are reversed, either the sidewalls 204/206 are slid in the direction 218 or the top panel 208 is slid in the direction 220.

[0068] It should be understood that once the projections P1-P5 are inserted into their corresponding chambers CH1-CH5, to releasably lock the sidewalls 204/206 to the top panel 208 or base panel 210, the sidewalls 204/206 are always slid in the direction towards the release button 214B while the top panel 208 or base panel 210 are slid in the opposite direction; conversely, to release the sidewalls 204/206 from the top panel 208 or base panel, once the release button 214 is depressed, the sidewalls 204/206 are always slid away in a direction away from the release button 214B while the top panel 208 or base panel 210 are slid in the opposite direction. And as mentioned previously, the mating surfaces can be simultaneously slid in opposite directions.

[0069] In particular, to release the top panel 208 and/or the base panel 210 from the corresponding sidewalls 204/206, the opposite process is followed. Firstly, the user will feel for the release button 214B which is seated in the cavity 216; the cavity 216 exposes a portion of the release button 214B to allow the user to depress the release button 214B against the bias of the V-shaped leaf spring 214A and then the sidewall(s) 204 and 206 are slid in a direction away from the release button 214B (FIGS. 27-28) and then the sidewalls 204/206 can be lifted out of the receptacle brackets 212.

[0070] FIGS. 30-32 show another RLM 22 configuration with two sets of projections PR1 and PR2 being positioned on the top edge of the long side of the furniture side panel FSP. Corresponding receptacle brackets 212A and 212B are located on the corresponding long edge of a furniture top panel FTP. Cavities 216 are also provided in the top edge of the long side of the furniture side panel FSP for seating the respective release buttons 214B from the receptacle brackets 212A and 212B. The same procedure discussed above for releasably assembling and disassembling the top panel FTP from the side panel FSP is used here also.

[0071] In particular, in FIG. 30, the projections PR1 and PR2 on the edge of the FSP are aligned with the corresponding channels in receptable brackets 212A and 212B, respectively, on the edge of the FTP. Next, the projections PR1 and PR2 are inserted into the respective receptacle brackets 212A and 212B and the FSP is partially slid in the direction 222 (or, the FTP is partially slid in the opposite direction 224); as shown, this partial sliding process depresses the release button 214B. And, as shown in FIG. 32, when the FSP is completely slid in the direction 222 (or the FTP is completely slid in the direction 224), the release buttons 214B seat into their respective cavities 216, thereby releasably locking the FSP and the FTP together. Conversely, to detach the FTP from the FSP, the reverse process is followed.

[0072] While the invention has been described in detail and with reference to specific examples thereof, it will be apparent to one skilled in the art that various changes and modifications can be made therein without departing from the spirit and scope thereof.
