Description

Foldable table

The utility model relates to a kind of desk, refers to a kind of foldable table especially.

Because foldable table has convenience harvesting and storing when depositing, and liked by masses, and it is the most common in the at present common foldable table structure with regard to relevant design as shown in Figure 8, the foot rest A of its structure mainly utilizes transverse link A11 to be connected to form two groups of supporting frame kenels by four steady arm A1 in mode facing each other, and make two groups of supporting frames be coupling with the alternating expression intersection, and articulate another Qian type bar B in one group supporting frame upper end horizontal to stopping bar C with one, two ends by this Qian type bar B taxi two rod ends and one supporting frame are articulated in a bottom surface, use to support and support desktop D, support only Qian type bar B by supporting stopping bar C simultaneously, to limit the angle that supports of foot rest A; And when folding, make two supporting frames of foot rest A fold relatively and make desktop D closing to place in foot rest A side, very save the space;

The above-mentioned structure of commonly using of detailed sight is not difficult to realize that it has remained a little weak point in fact, and main cause is summarized as follows:

1. the foot rest of this structure is to utilize steady arm to articulate with interleaved mode to form, by the top ends supporting desktop of each steady arm; Yet this foot rest only supports angle by supporting the stopping bar qualification because the intersection pivot joint forms, if when carrying big loading, easily make to stopping bar generation deflection, so this kind structure can't be carried big loading in the use at all.

2. this kind structure is enough to supporting desktop though have 4 strong points owing to be to form in the interlaced pivot joint of steady arm, yet, if when having weight to be placed on the side of foldable table, make easily foldable table overturn and topple over that its steadiness is not good.

The purpose of this utility model provides and a kind ofly supports firm and can bear the greater weight foldable table.

For achieving the above object, solution of the present utility model is: a kind of foldable table, mainly comprise members such as support foot rest and table, support foot rest is a condensation or the support body that supports relatively, table is one to be flat on the support foot rest that supports, and the plate body that when support foot rest folds, can lift off, wherein: support foot rest is by the four upright sheathed bearings in stay pipe bottom, establish in this bearing and stand pole and axially be extended through in the stay pipe, stay pipe that support foot rest two sides are adjacent one another are and bearing are provided with interconnective cross bar thereon in mode facing each other, and between two side stay pipes, be provided with some groups and be the shrinking connecting-rod group that intersection articulates, this shrinking connecting-rod group is formed by staggered pivot joint of connecting rod that two ends are provided with sleeve pipe, and sleeve pipe is socketed on respectively on the cross bar of stay pipe and bearing; Table bottom surface two sides are oppositely arranged stopping plate, then are installed with guide rod between two stopping plates, and top ends pivot knot one spacer that is extended through between table face and guide rod of this support foot rest one side cooperates the relative guide rod of a bond pad to support and fixes on the spacer of support foot rest.

Behind the employing such scheme, because foldable table is on average to be supported to arrive in the table bottom surface by four stay pipes, can support bigger weight, general foldable table is more firm sturdy in the support, does not overturn the situation generation of toppling over and do not have to shamble to cause.

Below in conjunction with accompanying drawing specific embodiment of the utility model is described in further detail.

As shown in Figure 1, the utility model mainly comprises two major parts such as support foot rest 1 and table 4, wherein:

Support foot rest 1 is linked in respectively on four bearings 12 by four upright stay pipes 11, establish in this bearing 12 and stand pole 121 and axially be extended through in the stay pipe 11, and on adjacent two stay pipes, 11 upper ends of two sides and bearing 12, be horizontally set with a cross bar 111 respectively and interconnected, and be provided with two groups 111 of cross bars and be the shrinking connecting-rod group 2 that intersection articulates, with stay pipe 11 synchronization actions that connect two sides, wherein, this shrinking connecting-rod group 2 is formed by connecting rod 22 staggered pivot joints that two ends are provided with sleeve pipe 2, be socketed on 111 of the last sheer poles of support foot rest 1 with its sleeve pipe 21, form the pivoting point of an activity; Again, two stay pipes, 11 tops of the side spacer 3 that laterally is pivoted in the support foot rest 1, this spacer 3 and two stay pipes, 11 articulated sections are shaped to pivot ear 31 shapes;

Relative two sides in table 4 bottom surfaces set firmly two stopping plates 41 that are the L type, and establish two detents 411 in the opposite face upper punch of two stopping plates 41, for two straight guide rod 42 build-ins location, and the bond pad 43 that cooperates one side to be provided with two conduits 431 (or arc groove) stretches through, and locking to tie at one stopping plate 41 sets firmly handle 44; Suitable place, table 4 bottom surfaces is provided with two positioning seats 45, and in the present embodiment, this positioning seat 45 is shaped to a tubulose, and on reality was used, this positioning seat 45 also may be molded to the groove shape or is shaped to projection, and stay pipe 11 gives spacing only to support.

When group is established, make the conduit 431 on two guide rods, the 42 relative bond pad 43 stretch through, and support lock by bond pad 43 and be fixed on the spacer 3 of support foot rest 1, and make table 4 can be connected on the support foot rest 1, during use, as Fig. 2, shown in 3, after making support foot rest 1 support vertically-arranged, hold again and get the vertical table 4 that pulls of handle 44 up, and after making table 4 extremely fix a point by guide rod 42 relative support foot rest 1 vertical slips, make its formation horizontal together with spacer 3 relative stay pipe 11 bending tables 4 again, be linked in the location, two stay pipes, 11 ends of support foot rest 1 with the positioning seat 45 of its bottom surface, supported table 4 bottom surfaces by four stay pipes, 11 ends, formed a complete foldable table as shown in Figure 4.

When amounting to, as shown in Figure 3, hold and get handle 44 interlock tables 4 and turn over up and lift to the state of standing (as shown in Figure 5), multiple conduit 431 slippages that make the guide rod 42 that is locked on the table 4 carry over bond pad 43 descend, because the stopping plate 41 of table bottom surface will abut against in spacer 3 and bond pad 43 edges, make table 4 can't be again slippage downwards and be the location shape, Fig. 6 for another example, shown in 7, make support foot rest 1 abut against by 2 relative table 4 condensations of two shrinking connecting-rod groups, at this moment, these four stay pipes 11 will with shrinking connecting-rod group 2 fold and the pole 121 that carries on the bearing 12 rise, make support foot rest 1 can place closing fully on 4 of the tables that stands.

Foldable table of the present utility model can support bigger weight owing to be on average to be supported to arrive in table 4 bottom surfaces by four stay pipes 11, and general foldable table is more firm sturdy in the support, does not overturn the situation generation of toppling over and do not have to shamble to cause.
