ADJUSTABLE FENCE

Abstract

An adjustable fence comprises two opposite posts, a slat assembly, and two buffering elements. The slat assembly has multiple detachable slats detachably mounted between the posts. The buffering elements are respectively mounted in the mounting slots of the posts, and each of the buffering elements is disposed between the post body of each of the posts and the slat assembly. Increasing or decreasing the detachable slats of the slat assembly adjusts the height of the adjustable fence for different applications. The pushing force resulting from the thermal expansion or/and contraction of the slat assembly or/and the post body is absorbed by the buffering element, so that the bottom bracket of the slat assembly and the post body do not push each other to be deformed.

[0037] With reference to FIGS. 1 to 3, and 11, the limits 30 are respectively mounted on the posts 10. The limits 30 are detachably mounted in the mounting slots 12 of the posts 10 respectively and press against the slat assembly 20 to prevent the slat assembly 20 from being disassembled from the posts 10 inadvertently. Each of the limits 30 has a mounting plate 31, a threaded hole 32, a pressing plate 33, a first fastener 34, and a second fastener 35. The mounting plate 31 of each of the limits 30 is mounted slidably in the mounting slits 1111 of each of the posts 10. The threaded hole 32 is formed through the mounting plate 31. The pressing plate 33 is formed on and protrudes from the mounting plate 31. The pressing plate 33 is pressed against the top bracket 23 of the slat assembly 20. The first fastener 34 of each of the limits 30 is mounted through the threaded hole 32. The first fasteners 34 of the limits 30 press tightly against the inner surfaces 111 of the posts 10 respectively. The second fastener 35 is mounted through the pressing plate 33 and the top bracket 23 of the slat assembly 20 to force the pressing plate 33 to press against the slat assembly 20 tightly. In an embodiment, the first fastener is a bolt and the second fastener is a screw.

[0038] With reference to FIG. 4, the buffering elements 40 are resilient. The buffering elements 40 are disposed in the mounting slots 12 of the posts 10 respectively. Each of the buffering elements 40 is disposed between the inner surface 111 of the post body 11 of each of the posts 10 and the terminals 223 of the bottom bracket 22 of the slat assembly 20. The buffering elements 40 are embedded in the terminals 223 of the bottom bracket 22 respectively. When the bottom bracket 22 and/or the post body 11 expand with heat and/or contract with cold, the pushing force between the bottom bracket 22 and the post body 11 is absorbed by the buffering elements 40. As such, the bottom bracket 22 and the post body 11 do not push each other to be deformed. In an embodiment, the buffering elements 40 are made from foaming material.

[0039] With reference to FIGS. 1, 11, and 12, multiple adjustable fences 1 of the present invention can be combined together to form a fence assembly or an enclosure. The slat assemblies 20 of two neighboring adjustable fences 1 are mounted on one post 10. The detachable slats 21, the bottom bracket 22, and the top bracket 23 of one of the two neighboring adjustable fences 1 are mounted in the mounting slot 12. The detachable slats 21, the bottom bracket 22, and the top bracket 23 of another adjustable fence 1 are mounted in one of the expanding slots 13. As such, combining multiple adjustable fences 1 of the present invention together for a fence assembly or an enclosure as desired is achieved.

[0040] Based on the above, the adjustable fence 1 has the following advantages.

[0041] The height of the adjustable fence 1 can be quickly changed by increasing or decreasing the detachable slats 21 of the slat assembly 20 for different applications. Therefore, adjusting the height of the adjustable fence 1 is easy and efficient.

[0042] The bottom bracket 22 guides the lowest detachable slat 21 to easily fit the bottom bracket 22 and prevents the detachable slats 21 from bending at an intermediate section due to a heavy total weight of the slat assembly 20. Therefore, the bottom bracket 22 plays an important role that guides and supports the slat assembly 20 to prevent any inadvertent deformation.

[0043] The top bracket 23 holds the detachable slats 21 to prevent the detachable slats 21 from being detached inadvertently.

[0044] The limits 30 with the first fastener 34 and the second fastener 35 securely hold and press against the slat assembly 20 to prevent the detachable slats 21 from being detached inadvertently and enhance an overall structural strength of the adjustable fence 1.

[0045] The pushing force resulting from the thermal expansion or/and contraction of the bottom bracket 23 or/and the post body 11 is absorbed by the buffering element 40, so that the bottom bracket 23 and the post body 11 do not push each other to be deformed.
