Abstract

A table assembly includes a top and four table leg assemblies are connected to an underside of the top. Each table leg assembly includes a U-shaped frame and a bush with a tapered inside and a tapered outside extends through a hole in the bottom of each bush. A securing sleeve is engaged with the tapered inside of each bush and a leg is securely inserted in the securing sleeve corresponding thereto. The legs assembly is easily assembled and dis-assembled. The bushes each have a cushion lip inclinedly extending from a top thereof and being in contact with the top so as to provide a cushion function for the load on the top.

Description

FIELD OF THE INVENTION

The present invention relates to a table leg or bench leg assembly that can be easily assembled and includes cushion feature.

BACKGROUND OF THE INVENTION

A conventional table or work bench generally includes a top with four legs and each leg is connected to an underside of the top. Some legs are pivotably connected to the top so as to be pivoted when not in use. The pivotable legs have to be cooperated with securing device which prevents the legs from pivoting suddenly. The securing device requires extra parts and extra time to be fixed to the underside of the top and the legs. Besides, the securing device is connected between the pivotable legs and the top so that the top is not directly connected to the top, this special arrangement might cause the securing device to be damaged because of the load.
The present invention intends to provide a table leg assembly which includes a bush with a cushion lip contacting the underside of the top and the leg is securely inserted into the tapered inside of the bush with a securing sleeve located therebetween. The leg assembly is easily to be assembled and dis-assembled, and the leg is securely positioned.

SUMMARY OF THE INVENTION

The present invention relates to a table assembly that comprises a top and four table leg assemblies connected to an underside of the top. Each table leg assembly includes a U-shaped frame, a bush, a securing sleeve and a leg. The frame has a hole defined through a bottom thereof and the bush having a tapered inside and a tapered outside extends through the hole in the corresponding frame. Each frame has a cushion lip extending inclinedly from a periphery of a top of the bush and the cushion lip is in contact with the underside of the top. A flange extends from a periphery of a bottom of the bush and is fixed to an underside of the frame. The securing sleeve is force-fitted with the tapered inside of the bush and the leg is securely engaged with an inside of the securing sleeve.
The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIGS. 1 to 4, the table assembly of the present invention comprises a top 10 and four table leg assemblies are connected to an underside of the top 10. Each table leg assembly includes a U-shaped frame 20, a bush 30, a securing sleeve 40 and a leg 50.
The frame 20 has an open top and a hollow interior and a hole 211 is defined through a bottom 21 thereof. The top 10 includes a skirt portion extending from each of tow ends thereof and each skirt portion includes a horizontal portion 11. The frames 20 each have a first side rested on the horizontal portions 11 and a contact portion 22 extends from a top edge of a second side thereof and the contact portion 22 is in contact with the underside of the top 10.
The bush 30 is made by metal and has a tapered inside and a tapered outside. The bush 30 extends through the hole 211 in the corresponding frame 20 and a cushion lip 32 extends inclinedly from a periphery of a top of the bush 30. The cushion lip 32 is in contact with the underside of the top 10. A flange 33 extends from a periphery of a bottom of the bush 30 and is fixed to an underside of the frame 20 by welding or glue. Each bush 30 includes a plurality of reinforcement ribs 31 extending radially from the tapered outside thereof.
The securing sleeve 40 is made by plastic material and force-fitted with the tapered inside of the bush 30 and the leg 50 is securely engaged with an inside of the securing sleeve 40. Each of the securing sleeves 40 includes a plurality of engaging portions 42 extending from an inside thereof and each of the legs 50 includes a plurality of grooves 51 defined in an outside thereof, the engaging portions 42 are engaged with the grooves 51. The inside of each of the securing sleeves 40 has even diameter so that the leg 50 has an even diameter. The inside of the securing sleeve 40 can also be tapered and the legs 50 have a tapered outside. As shown in FIG. 5, a positioning bolt 60 may extend through the frame 20 and contacts the outside of the bush 30 to further position the bush 30.
The table assembly is easily assembled and dis-assembled. The engagement between the tapered securing sleeves 40 and the tapered bushes 30 securely position the legs 50 so that the assembly is secured and reliable. The cushion lip 32 of each bush 30 provides a proper cushion feature when a heavy load is put on the top so as to properly protect the legs 50.
While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
