Description

Sheath for adjustable desk and chair legs

This new model relates to the technical field of furniture, and particularly relates to a sheath of adjustable desk and chair legs.

A table is a kind of furniture, mainly composed of a plane and a bracket, used for holding objects, and usually appears with a chair. The table may have drawers, such as a desk, writing desk, mahjong table, dressing table, etc.

In order to make the table stand on the ground, the four corners of the table are usually equipped with brackets, and the brackets are generally called table legs. One end of the table legs is connected to the plane of the table, and the other end of the table legs stands on the ground. However, when users move the table, they often move by dragging, so that the table legs standing on the ground will rub against the ground excessively during the movement. The uneven wear of a table leg will eventually cause the table to shake when standing on the ground.

In view of this, it is indeed necessary to provide a technical means to solve the problem that the table legs are prone to excessive friction during use and cause uneven wear of the table legs.

The purpose of the present invention is to solve the problem that the table legs are prone to excessive friction during use and cause uneven wear of the table legs.

In order to solve the aforementioned problems, the present invention is an adjustable desk and chair leg sheath, suitable for a desk leg or chair leg, and the adjustable desk and chair leg sheath includes: a set of shells with self-contained One end of the recessed set of holes, by allowing the table leg or chair leg to extend into the set hole, so as to set the cover on the table leg or chair leg, and the cover has a hole surrounding the set of holes An inner ring surface, and the inner ring surface is composed of at least two planes, an angle is sandwiched between the two planes, and a stud is provided on the sleeve; a bearing seat is arranged in the sleeve hole, and the bearing seat It has an outer ring surface, the outer ring surface is shaped according to the shape of the inner ring surface, so that the outer ring surface abuts against the inner ring surface; a base has a screw hole screwed on the stud.

In a preferred embodiment, the sleeve is rectangular, and the sleeve hole is also a rectangular hole, and the sleeve hole is recessed from one end of the sleeve so that one end of the sleeve is open.

In a preferred embodiment, the screw hole is recessed from the top surface of the chassis.

In a preferred embodiment, the base is trapezoidal.

Since the table leg or chair leg is protected in the casing, and the table leg or chair leg does not directly touch the ground, the problem of the table leg being worn can be prevented. Even better, after a long period of use, the base may be worn out, causing the height of each table foot to be different. At this time, the user can rotate the base to match the screw holes of the base with the screw holes of the socket. When the user rotates the base, the holder can move along the vertical direction. When the holder is farther away from the base, the holder can support the height of the table leg or chair leg. The height of each table leg is different to adjust the base correspondingly, so that the height of each table leg and the corresponding combined sheath can be the same height, and the problem of shaking or unevenness caused by the different height of the table leg can be prevented.

Please refer to Figures 1 to 3, this new model is an adjustable desk and chair leg sheath, suitable for a table leg or chair leg 10, the table leg or chair leg 10 is not limited to use, including desks, desks , Dining table, cabinet... etc., can be equipped with the table leg or chair leg 10, and the sheath of the adjustable desk and chair leg mainly has a shell 20, a bearing 30, and a base 40, among which: the The cover 20 has a set of holes 21 recessed from one end thereof. By extending the table leg or chair leg 10 into the set of holes 21, the cover 20 is placed on the table leg or chair leg 10. The sleeve 20 has an inner ring surface 22 surrounding the sleeve hole 21, the inner ring surface 22 is composed of at least two planes, and there is an angle between the two planes, and the sleeve 20 is provided with a stud 23 In this embodiment, the sleeve 20 is rectangular, and the sleeve hole 21 is also a rectangular hole. The sleeve hole 21 is recessed from one end of the sleeve 20 so that one end of the sleeve 20 is open.

The socket 30 is disposed in the sleeve hole 21, and the socket 30 has an outer ring surface 31, the outer ring surface 31 is shaped according to the shape of the inner ring surface 22, so that the outer ring surface 31 abuts against the inner ring surface 31 Annular surface 22; in this embodiment, the socket 30 can be made of plastic, rubber... and other materials, the socket 30 is rectangular and has a top surface 33 and a bottom surface 34, the top surface 33 for abutting For the table leg or chair leg 10, the bottom surface 34 is provided to lean against the bottom surface of the sleeve hole 21.

The base 40 has a chassis 41 and a screw hole 42, and the screw hole 42 is screw-locked to the screw hole 23; in this embodiment, the screw hole 42 is recessed from the top surface of the chassis 41, so that when the When the screw hole 42 and the stud 32 are screwed to the screw hole 32, the chassis 41 can receive and abut against the socket 30 and the casing 20.

3 and 4, in another embodiment, the shape of the base 40 is a trapezoid, and the smaller side of the base 40 is the top surface, and the larger side is the bottom surface, and the top surface is provided for abutting against the Sleeve 20. Since the base 40 is trapezoidal, the area of the base 40 contacting the ground is larger, and the base 40 can stand on the ground more stably.

The above is the structure configuration and connection relationship of the new model in a preferred embodiment. The use of the present model and the effects it can produce are as follows: Please refer to Figure 1 and Figure 2. In use, the user The table leg or chair leg 10 can be directly extended into the sleeve hole 21 of the casing 20, so that the table leg or chair leg 10 is accommodated in the sleeve hole 21, and the bottom surface 34 of the table leg or chair leg 10 rests When resting on the seat 30, since the table leg or chair leg 10 is protected in the casing 20, and the table leg or chair leg 10 will not directly touch the ground, the problem of abrasion of the table leg 10 can be prevented .

More preferably, after a long time of use, the base 40 may be worn out, causing the height of each table leg 10 to be different. At this time, the user can rotate the base 40 through the screw hole 42 of the base 40 and the seat. The studs 32 of 30 cooperate, so that when the user rotates the base 40, the bearing 30 can move along the vertical direction Y. When the bearing 30 is farther away from the base 40, the bearing 30 can be raised The height of the table leg or chair leg 10 allows the user to adjust the base 40 according to the height of each table leg 10, so that the height of each table leg 10 and the corresponding combined sheath can be the same height, preventing Different heights of the table legs 10 cause shaking or unevenness.
