Description

[Detailed Description of the Invention] The present invention relates to a height adjustment device for a desk, and more particularly to a height adjustment device that uses a temporary support to easily perform adjustment operations when adjusting the height of a desk.

Conventionally, in order to adjust the height of a desk by using a number of holes drilled at predetermined intervals in the vertical direction on either side plate or leg body, the side plate had to be completely separated and the side plate had to be lifted up to the desired height. It is extremely time consuming to maintain the setting, align the holes for screwing, and keep lifting the side plate to the same position until the screws are inserted.

The present invention was devised to eliminate the above-mentioned trouble, and its gist is that holes 9 are bored at predetermined intervals in the vertical direction in either the side plate 3 or the legs 4, and the lower end of the side plate 3 Fitting the protruding shaft 12 of the temporary holder into the hole 9, which has one end edge that can come into contact with the edge or the upper end edge of the leg body 4, and has a protruding shaft 12 on the side that can be removably fitted into the hole 9. Support the lower edge of the side plate 3 or the upper edge of the leg 4 with one edge of the temporary support, and temporarily set the side plate 3 at a predetermined support height before connecting and fixing the side plate 3 and the leg 4. I would like to support you.

The details will be explained based on the embodiment shown in the attached drawings below.The legs 4 are inscribed or circumscribed on the side plates 3, 3 which are integrally connected to the top plate 2 of the desk 1, or can be moved up and down from below. Holes 5 are formed at regular intervals in the vertical direction on the front and rear edges of either the fitting legs 4 or the side plates 3.
At the same time, screw holes 6, 6 are formed in the other side of the leg body 4 or the side plate 3, and screw holes 6, 6 that can match with the holes 5, etc., are formed, and screws 7, 7 are inserted through the holes 5, having a desired height.
Alternatively, the desk top plate 2 can be adjusted and held at a predetermined height by screwing bolts into the screw holes 6, 6, and the desk top plate 2 can be adjusted and held by removing the screws 7, 7 or the bolts. A temporary support 8 for temporarily supporting the side plate 3 when adjusting the height is attached by removably fitting the projecting shaft 12 into the hole 9 formed in the leg body 4 or the side plate 3. The side plate 3 is supported, and therefore at least the same number of holes 9 are formed at the same intervals as the holes 5, and the table top plate 2 is temporarily supported at a predetermined support height position by the screws 7 or bolts. The shape and configuration are not limited in any way, and it has one edge that can come into contact with the lower edge of the side plate 3 or the upper edge of the leg 4, and has a hole 9 on the side.
It does not need to be a single unit as long as it has a protruding shaft 12 that can be removably fitted to the holder, and it can be placed in a position where it can fit into the holes 9, 9 formed in two rows at the front and back, as shown in Fig. 3. The two protruding shafts 12, 12 may be arranged, or the first
As shown in Figures 2 and 2, if the central part is made thinner to form a handle part 10, the temporary holder 8 can be easily attached and removed, and the handle part 10 can also be used as a handle when moving the desk. Can be used. Further, in this embodiment, a recess is formed at the lower end of the side plate or the upper end of the leg, and at least in FIG.
The side plate 3 and the desk top plate 2 can be temporarily supported at a predetermined height by making contact with the lower edge of the upper recess 14, or the upper edge of the upper recess 14 in FIG. It is. Furthermore, in order to prevent the temporary holder 8 itself from falling off in this temporarily supported state, upward or downward protrusions 15 are formed on the support parts 11 located at both ends, and the lower recess 13 of the side plate 3 or the upper recess of the leg body 4 is provided. It can be fitted into a recessed hole 16 formed on the edge surface of the position 14, thereby eliminating rattling and realizing reliable position regulation.

According to the height adjustment device of the present invention as described above, while the top plate 2, that is, the side plate 3 is supported at a predetermined height by the screws 7 or bolts, the temporary holder 8 is inserted into the hole 9 with its protruding shaft 12... It is attached to the desired height position of the side plate 3 or leg body 4 by selectively fitting it to the side plate 3 or the leg body 4, and then removing the screws 7 or bolts and moving the side plate 3 up and down together with the desk top plate 2 to temporarily mount it. The height of the desk top 2 can be adjusted by supporting it on the fixture 8 and connecting the side plate 3 and the legs 4 again with the screws 7 or bolts. There is no need for the troublesome operation of completely removing it from 4 and adjusting the height, and it can be done extremely easily by simply attaching the temporary holder 8 to the outer surface of the side plate 3 or the leg 4. This eliminates the drawback of requiring time and effort to align the screws and screw holes each time the top plate is adjusted up or down.
