Abstract

For improvement on the firm structure and function of a folding desk of prior art, with the proper mechanism for making it foldable built by means of either the two center-pivoted parallel linking rods connecting the front pair and the rear pair of legs or the two symmetrical pairs of pivoted X-type crossing legs, this innovative design provides with two grooved and hooked parallel linking rods under the desk top on the right side and the left side in the folding direction corresponding in position to the supporting legs, which are installed in such a way that each pin horizontally mounted on the topper end of each rear leg remains inside each groove allowing the linking rod to travel within the range of said groove and the hook formed outside the other end of said groove of each linking rod may be engaged with or released from the pin horizontally mounted on the topper end of each front leg allowing the lock or lift of this the desk top.

Description

Folding table

This creation relates to how to improve the structure of the prior art folding table to enhance its stability and use function.

There are two folding tables in the prior art. One of them, as shown in Figure 1 (A) (New Type M416388) FD-A, the front and rear pairs of feet (010 and 0120) are combined by a central hub The connecting rods (040 and 051) allow them to be opened or closed, and on the other hand, the table top (030) can be opened from the front end and then fixed to the bottom surface of the table by means of a groove (021) accommodated in the rear pair of feet. The hub (031) landed along this trench. Such a table is unstable in an open state unless other necessary components are applied. Alternatively, as shown in Fig. 1(B), the FD-Bs of the two pairs of symmetrical feet (110 and 120) on the inner and outer sides are X-shapedly coupled to each other by a hinge. However, one of the pair (110) and the table top (130) are partially connected to each other by a hub (110b), and are further pivotally coupled to the remaining body (110a), so that when the other end is pivotally coupled to the other one The table top of the foot can be tilted toward the direction of the divided pair of feet when the two pairs of legs are folded inward. Otherwise the tabletop of this table cannot be opened separately.

The key mechanism for the improvement of the prior art described above, that is, the novel content, is applicable to a folding table similar to FD-A (hereinafter referred to as FD-A) and a folding table similar to FD-B (hereinafter referred to as Is similar to FD-B).

A connecting rod having a sulcus and a hook corresponding to the left and right sides of the table top and parallel to the left and right sides of the folding direction is fixed, and the structure and the device are arranged such that the short column protruding laterally above the rear legs can be left. The hooks in the glide of the table slide, and the hooks placed outside the other end of the gutter can contain or break away from the short columns protruding laterally above the front legs; thus eliminating the need for additional facilities like FD-A to temporarily fix the tabletop In the case of two pairs of feet, and without having to be similar to FD-B, it is necessary to divide the upper paragraph of one pair of feet and then connect them by a hub. These short columns can also be threaded and bolted, or other facilities, so they can be used to lock or loosen the two links. The above-mentioned rear short column also has the function of hooking the table. For a similar FD-B, such a device has the added benefit that it is not necessary to fold the front and rear legs simultaneously.

Figures 1(A) and (B) show the construction of two folding tables of the prior art, FD-A and FD-B, respectively. Figures 2(A) and (B) respectively show two folding tables, similar to FD-A and FD-B-like configurations, referred to by the novel content.

According to the above novel content, Fig. 2(A) shows an example of materialization, and Fig. 2(B) shows another example.

As shown in Figure 2 (A), the two devices fixed on the bottom of the table top (230) The connecting rods (260) having the gully (261) and the hook (262) parallel to each other correspond to the two legs on the same side of the front and rear pairs of legs (210 and 220). Each of the short columns (221) fixed in the lateral direction of the rear pair of feet is placed in each of the corresponding sulcus, so that the link is allowed to slide back and forth and up and down in the range of the sulcus. The position and size of the hook (262) disposed outside the sulcus (261) at the other end of the connecting rod (260) can stably contain a short column that is fixed in the lateral direction of the upper pair of the foot and is released, so that the horizontal The foldable links (240 and 250) that span the front and rear legs are stably opened or closed.

As shown in Fig. 2(B), two fixed parallel devices (341 and 351) and hooks (350 and 351) are attached to the table top (330), corresponding to each other. Two legs on the same side of the front and rear pairs of feet (310 and 320). When the hooks (342) and (352) each contain a short column (321) corresponding to the front, the table remains open. When the hooks (342) and (352) are each separated from the front short column (321), during the folding/opening of the table, the table top (330) can be along the bottom of the link in the range of the sulcus (341 and 351). The short column (311) corresponding to the rear side is slid up and down or up.
