Description

Technical Field

[0001] This invention relates to the field of joining structures for modular screens, and more particularly to a screen joining element. Background Technology

[0002] Modular partitions are a common type of furniture used in general office environments. The assembly of partitions includes the joining of partitions with each other, or the joining of partitions with turning elements or edge finishing elements.

[0003] A screen joining element is an item fixed to the edge of a screen to provide a joining structure. It usually has several protruding metal hooks or latches and corresponding structures to form a screen joining element between two screens. In addition to its relatively complex structure, it also has many protruding objects or gaps. Therefore, when continuously joining screens, the size and thickness of the screen joining element will affect the aesthetics of the screen, and decorations must be added to cover it.

[0004] Meanwhile, protruding components such as metal hooks or lock plates are often deformed due to accidental collisions during handling, assembly, or disassembly, or they can easily scratch surrounding items or people. In view of this, the present invention has developed and improved the shortcomings of screen joining components. Summary of the Invention

[0005] To facilitate the explanation of the technical features of the present invention, the directional descriptions "left-right direction", "front-back direction" and "up-down direction" described below are used to distinguish the three-dimensional directions relative to the screen joining element, and are not used to limit the absolute direction of the screen joining element in the environment.

[0006] The main objective of this invention is to provide a screen joining element that is easy to install, aesthetically pleasing, durable, and space-saving. To achieve the aforementioned objective, the screen joining element of this invention includes: a first L-shaped joining rail, one side of which is a first joining piece, and the other side is a first fastening piece; and a second L-shaped joining rail, wherein the cross-section of the second L-shaped joining rail has the same shape and size as the cross-section of the first L-shaped joining rail, one side of which is a second joining piece, and the other side is a second fastening piece; the first fastening piece fastens to the edge of the second joining piece, and the second fastening piece fastens to the edge of the first joining piece, so that the first L-shaped joining rail and the second L-shaped joining rail are interlocked, and that the first L-shaped joining rail and the second L-shaped joining rail can slide vertically but cannot separate horizontally.

[0007] In one embodiment, at least one first engaging block is provided on the inner side of the first engaging piece, and at least one second engaging block is provided on the inner side of the second engaging piece. The at least one first engaging block and the at least one second engaging block are in a corresponding shape that engages in the vertical direction. When the at least one first engaging block engages with the at least one second engaging block, the first L-shaped engaging rail and the second L-shaped engaging rail are in a front-back engaging state.

[0008] In one embodiment, at least one first engaging block is fixed to a first engaging piece by a plurality of first bolts, the plurality of first bolts passing from the inside of the first engaging piece to the outside of the first engaging piece; at least one second engaging block is fixed to a second engaging piece by a plurality of second bolts, the plurality of second bolts passing from the inside of the second engaging piece to the outside of the second engaging piece.

[0009] In one embodiment, a first stop is provided on the inner side of the first engagement piece above at least one first engagement block, and a first distance is maintained between the first stop and the first engagement block. A second stop is provided on the inner side of the second engagement piece above at least one second engagement block, and a second distance is maintained between the second stop and the second engagement block.

[0010] In one embodiment, the first stop is fixed to the first connecting piece by a plurality of third bolts, the plurality of third bolts passing from the inside of the first connecting piece to the outside of the first connecting piece; the second stop is fixed to the second connecting piece by a plurality of fourth bolts, the plurality of fourth bolts passing from the inside of the second connecting piece to the outside of the second connecting piece.

[0011] In one embodiment, the first locking block has a first Z-shaped tenon, and the second locking block has a second Z-shaped tenon. The first Z-shaped tenon and the second Z-shaped tenon are interlocked in an up-down direction.

[0012] In one embodiment, the edge of the first connecting piece is provided with a first fastening groove, the edge of the first fastening piece is provided with a first fastening hook, the edge of the second connecting piece is provided with a second fastening groove, and the edge of the second fastening piece is provided with a second fastening hook; the first fastening hook engages with the second fastening groove, and the second fastening hook engages with the first fastening groove.

[0013] In one embodiment, the outer side of the first bonding piece is provided with a first T-groove, and the outer side of the second bonding piece is provided with a second T-groove.

[0014] In one embodiment, the first L-shaped connecting rail and the second L-shaped connecting rail are made of aluminum.

[0015] In one embodiment, the first connecting piece is provided with a plurality of first bolt holes, and the second connecting piece is provided with a plurality of second bolt holes.

[0016] In one embodiment, the first and second locking blocks are made of plastic or glass fiber.

[0017] In one embodiment, the first and second blocks are made of plastic or fiberglass.

[0018] Compared to existing technologies, the first and second L-shaped connecting rails, even before being joined together, create a semi-concealed area through the recesses of their L-shaped structures. This allows various joining or fixing components to be placed within this semi-concealed area. This prevents components from protruding and easily scratching the surrounding environment or people, or being damaged by impact, making the screen's connecting components safer and more durable. Secondly, when the first and second L-shaped connecting rails are joined together, they completely conceal various joining or fixing components, offering advantages such as easy installation, aesthetics, and space-saving design. Furthermore, unlike sharp or protruding hooks or locking plates, the first latch, second latch, first stop, or second stop are concealed within the area created by the L-shaped structure of the first or second L-shaped connecting rail. This not only reduces the risk of collision or damage but also provides a stable connection between the first and second L-shaped connecting rails without using excessive materials or occupying too much space, and also facilitates installation and disassembly. In addition, when the first locking block, second locking block, first stop block, or second stop block is made of plastic or fiberglass, it can be easily replaced in case of damage or malfunction. Furthermore, the first bolt, second bolt, third bolt, and fourth bolt, besides fixing the first locking block, second locking block, first stop block, and second stop block respectively to the first L-shaped connecting rail or the second L-shaped connecting rail, can also be used to lock the first L-shaped connecting rail or the second L-shaped connecting rail to the corresponding screen edge, making the assembly of the first L-shaped connecting rail or the second L-shaped connecting rail to the screen easier. The provision of the first bolt hole and the second bolt hole makes it easier to adjust the assembly position of the first locking block, second locking block, first stop block, and second stop block. The following examples illustrate preferred embodiments of the invention, and are described in conjunction with the accompanying drawings. Attached Figure Description

[0064] For ease of explanation, the following diagrams and descriptions use the left-right direction (x), the front-back direction (y), and the up-down direction (z) to represent the differences in the three-dimensional directions relative to the screen joining element 1.

[0065] Please see Figure 1 and Figure 2 As shown, the screen joining element 1 can be used for joining screens 2 together, or for joining screen 2 with a turning element (not shown) or an edge finishing element (not shown). The screen joining element 1 includes a first L-shaped joining rail 10 and a second L-shaped joining rail 20, the cross-section of the second L-shaped joining rail 20 having the same shape and size as the cross-section of the first L-shaped joining rail 10.

[0066] Please see Figure 2 , Figure 3 and Figure 4As shown, the first L-shaped connecting rail 10 has a first connecting piece 11 on one side and a first fastening piece 12 on the other side, with the first fastening piece 12 vertically connected to the first connecting piece 11. The recess of the first L-shaped connecting rail 10 can be used to create a semi-shaded section 10a. The inner side of the first connecting piece 11 faces the section 10a and is provided with a plurality of first engaging blocks 13 (in this embodiment, two first engaging blocks 13 are used for illustration). A first stop 14 is provided on the inner side of the first connecting piece 11 above the first engaging block 13, and a first distance h1 is maintained between the first stop 14 and the first engaging block 13.

[0067] The first engaging block 13 is fixed to the first connecting piece 11 by a plurality of first bolts 15, which pass from the inside to the outside of the first connecting piece 11. The first stop block 14 is fixed to the first connecting piece 11 by a plurality of third bolts 16, which pass from the inside to the outside of the first connecting piece 11. In practice, a plurality of first bolt holes 112 can be pre-set on the first connecting piece 11 to facilitate the selection of the optimal insertion positions of the first bolts 15 and the third bolts 16, thereby quickly positioning the first engaging block 13 and the first stop block 14.

[0068] The first locking block 13 has a first Z-shaped tenon 131, which protrudes from the first locking block 13. The protrusion distance of the first Z-shaped tenon 131 is greater than that of the bolt head of the first bolt 15, so as to conceal the bolt head of the first bolt 15.

[0069] Please see Figure 2 , Figure 5 and Figure 6 As shown, the second L-shaped connecting rail 20 has a second connecting piece 21 on one side and a second fastening piece 22 on the other side, with the second fastening piece 22 vertically connected to the second connecting piece 21. The recess of the second L-shaped connecting rail 20 can be used to create a semi-shaded section 20a. The inner side of the second connecting piece 21 faces the section 20a and is provided with multiple second engaging blocks 23 (the number of which is related to the...). Figure 4 (As shown in the diagram, the first engaging block 13 corresponds to this). The inner side of the second engaging piece 21 is provided with a second stop 24 above the second engaging block 23, and a second distance h2 is maintained between the second stop 24 and the second engaging block 23.

[0070] The second engaging block 23 is fixed to the second engaging piece 21 by a plurality of second bolts 25, the plurality of second bolts 25 passing from the inside to the outside of the second engaging piece 21. The second stop block 24 is fixed to the second engaging piece 21 by a plurality of fourth bolts 26, the plurality of fourth bolts 26 passing from the inside to the outside of the second engaging piece 21.

[0071] The second engaging block 23 has a second Z-shaped tenon 231, which protrudes from the second engaging block 23. The protrusion distance of the second Z-shaped tenon 231 is greater than that of the bolt head of the second bolt 25, so as to conceal the bolt head of the second bolt 25. In implementation, a plurality of second bolt holes 212 can be pre-set on the second connecting piece 21 to facilitate the selection of the optimal insertion position of the second bolt 25 and the fourth bolt 26, thereby quickly positioning the second engaging block 23 and the second stop block 24.

[0072] Please see Figure 7 , Figure 8 and Figure 9 As shown, and also refer to Figure 4 and Figure 6 As shown, the edge of the first connecting piece 11 is provided with a first fastening groove 111, the edge of the first fastening piece 12 is provided with a first fastening hook 121, the edge of the second connecting piece 21 is provided with a second fastening groove 211, and the edge of the second fastening piece 22 is provided with a second fastening hook 221. When the first L-shaped connecting rail 10 and the second L-shaped connecting rail 20 are fastened, the first fastening hook 121 is first fastened into the second fastening groove 211, and the second fastening hook 221 is fastened into the first fastening groove 111, so that the first fastening piece 12 is fastened to the edge of the second connecting piece 21, and the second fastening piece 22 is fastened to the edge of the first connecting piece 11. The first L-shaped connecting rail 10 and the second L-shaped connecting rail can then initially fasten to each other. At this time, the first L-shaped connecting rail 10 and the second L-shaped connecting rail 20 can slide in the vertical direction z but cannot separate in the horizontal direction x.

[0073] The first locking block 13 and the second locking block 23 can be configured to interlock or separate in the vertical direction (z) by means of the first Z-shaped locking tenon 131 and the second Z-shaped locking tenon 231. When the first L-shaped connecting rail 10 and the second L-shaped connecting rail 20 slide in the vertical direction (z), they can be used to engage or disengage the first Z-shaped locking tenon 131 and the second Z-shaped locking tenon 231.

[0074] When the first Z-shaped latch 131 and the second Z-shaped latch 231 are inserted into each other from the top and bottom (z direction), the first L-shaped connecting rail 10, through the first Z-shaped latch 131 and the first fastener 12, clamps the second Z-shaped latch 231 and the second connecting piece 21 of the second L-shaped connecting rail 20. At the same time, the second L-shaped connecting rail 20 also clamps the first Z-shaped latch 131 and the first connecting piece 11 of the first L-shaped connecting rail 10 through the second Z-shaped latch 231 and the second fastener 22. This prevents the first L-shaped connecting rail 10 and the second L-shaped connecting rail 20 from separating in the front and back (y direction), thus completing the connection between the first L-shaped connecting rail 10 and the second L-shaped connecting rail 20.

[0075] The first stop 14 and the second stop 24 have a mutual blocking function, which can be used to limit excessive sliding in the vertical direction z between the first L-shaped connecting rail 10 and the second L-shaped connecting rail 20, so as to suppress one side of the screen 2 (such as Figure 2 The lifting distance when the first L-shaped connecting rail 10 and the second L-shaped connecting rail 20 are accidentally lifted (as shown). The setting of the first gap h1 and the second gap h2 allows for an appropriate sliding stroke between the first L-shaped connecting rail 10 and the second L-shaped connecting rail 20, and also prevents the first L-shaped connecting rail 10 and the second L-shaped connecting rail 20 from accidentally becoming loose. In this embodiment, when the first L-shaped connecting rail 10 and the second L-shaped connecting rail 20 are engaged, the first gap h1 allows the second engaging block 23, which is located at the upper position as shown in the figure, to be inserted. After the second engaging block 23 enters the first gap h1, it slides down to the position where it engages the first engaging block 13. The second gap h2 can be used to accommodate the insertion of the first stop 14, so that the first stop 14 is located below the second stop 24. When the second engaging block 23 slides down to engage the first engaging block 13, the second stop 24 just contacts the first stop 14, thus stopping the second engaging block 23 and the entire second L-shaped engaging rail 20 from continuing to slide down. Through the cooperation of the first stop 14 and the second stop 24, the load and impact force on the first fastener 12 can be blocked and distributed. When one side of the screen 2 is accidentally lifted, the second fastener 22 will be restricted in its sliding stroke by the first stop 14 to prevent the first L-shaped engaging rail 10 and the second L-shaped engaging rail 20 from loosening. The second stop 24 and the first stop 14 can be locked together by the positioning bolt 3 (e.g., Figure 8 As shown), this creates a locked state between the first L-shaped connecting rail 10 and the second L-shaped connecting rail 20, preventing them from sliding.

[0076] To facilitate the connection of screen joining element 1 with screen accessories other than screen 2, such as turning elements (not shown in the figure) or edge finishing elements (not shown in the figure), the outer side of the first joining piece 11 is provided with a first T-slot 17, and the outer side of the second joining piece 21 is provided with a second T-slot 27. When the screen accessory is provided with a T-shaped connector corresponding to the first T-slot 17 and the second joining piece 21 (not shown in the figure), it can be assembled with the screen accessory through the first T-slot 17 or the second T-slot 27; or the screen 2 can also be provided with a T-shaped connector (not shown in the figure) to enhance the fixing effect between the screen 2 and the first T-slot 17 or the second T-slot 27.

[0077] As described above and shown in the figures, the first L-shaped connecting rail 10 and the second L-shaped connecting rail 20 can be quickly interlocked and installed by simple pushing (sliding), without creating gaps at the edges. They have many advantages, such as small space occupation, aesthetics, durability, easy assembly, and good connection.

[0078] The above description is merely illustrative of preferred embodiments of the present invention and is not intended to limit the scope of the present invention. Any simple substitutions and equivalent changes made in accordance with the claims and description of the present invention shall fall within the scope of the claims of the present invention.
