Abstract

The utility model discloses a vertical extendible table which is designed to make the height adjustment of the lifting table simple and flexible, and the adjustable range of the height increase. The table panel of the vertical extendible table is supported by an extendible shelf at the both sides of the table. The distance between the supporting point is altered by the movement and a pulley wheel fixedly installed at one end of the extendible shelf. Therefore, the extendible shelf deforms to reach the purpose of lifting and folding of the table. The lifting process of the table only need to push an operating lever. At the same time, locator cards at the both sides of the pulley wheel can carry out abdication, shift, and target to complete the lifting process. The adjustable range of the height is large, which can fit for the requirement of people in each age hierarchy, from infancy to old age.

Description

Vertical extendible table

The utility model relates to a kind of desk with lifting, folder function, belongs to the furniture class.

People need to have in the family desk with its body-accommodating in each age period, particularly in the stage of development from child to youth.Chinese residents living space is less to be long-standing problem, and this just need have the family expenses table of lifting, folder function.Existing same table can be divided into two classes substantially, and a class is to rely on the screw location, and a class is to rely on screw rod, slide bar location.Last class displacement needs tool operation, and more loaded down with trivial details, back one class technological requirement and production cost are higher, all is not suitable for family and uses.

No. 88216773.1 literary compositions of Chinese patent application have proposed a kind of folding same table that is suitable for family expenses with arm support supporting desktop plate, this embeds in the recessed lattice different in the recessed frid of desktop by the bayonet lock that is installed in support one end, determine the distance between fulcrum, thereby determine the differing heights of desk.But this desk needs in the table both sides bayonet lock to be extracted in recessed lattice respectively in lifting process, moves in another recessed lattice again, and is more loaded down with trivial details.And, being the unlikely inconvenience that causes in the use, the distance of arm support between ground supports point can not be too much surpass the length of corresponding desktop, thereby this height change is less.

The purpose of this utility model is will provide a kind of to have lifting, folder function and be fit to the desk that family uses, and it can make the lifting of desk once finish by the operation of people's several successive, and height change can adapt to each ages people's needs.

The purpose of this utility model is achieved in that the telescope support support of the desktop of desk by its both sides, fixedly connected with sheer pole by cross tube between two side stands, arrangement for adjusting height comprises positioning seat, fixed mount, locator card, pulley, control stick, axle center bar and connecting rod, the fulcrum of desktop one end under the desk folded situation with an end support table body of telescope support lower floor hack lever.One end of telescope support upper strata hack lever is connected with the fixed mount bearing pin, and the other end is connected with the pulley spindle core bar, by motion and fixed block, changes and fixes distance between two strong points, makes the telescope support distortion, realizes the lifting of desk and folding.

The utility model is because the arrangement for adjusting height that has adopted pulley, locator card, positioning seat, control stick and axle center bar etc. to form, when locator card shifts out from positioning seat or inserts, under the cooperation of pulley, axle center bar and control stick, realize displacement by rotating, mechanical movement when having reduced deformation of timbering, and two side stand displacements, distortion once finish synchronously, thereby descending operation is easy to be laborsaving.Simultaneously, because the telescope support supporting desktop plate that adopts two layers of intersection hack lever to form, be less than or equal at lower floor's hack lever under the situation of corresponding desktop length, telescope support can fully be out of shape in the allowed band that desktop supports, and the distance between ground supports point can not surpass the length of corresponding desktop too much, when the desktop respective length was not less than 0.6 meter, this height can rise to 0.8 meter by 0.2 meter.

The concrete structure of the vertical extension table of utility model is provided by the following drawings and embodiment.

The vertical extension table construction profile of Fig. 1.

Fig. 4 locator card (4) is given up the throne in positioning seat (2), weighs up schematic diagram.

Each parts connection layout of the vertical extension table of Fig. 5.

The vertical extension table contour structures of Fig. 6 schematic diagram.

Referring to Fig. 1, Fig. 2, Fig. 5, example structure of the present utility model comprises: desktop (1) is supported by the telescope support (6) of its both sides under working condition, support (6) is made up of two layers of intersection hack lever, and two side stands (6) are fixedlyed connected with sheer pole (12) by cross tube (11).One end on support (6) upper strata is connected with fixed mount (3) bearing pin, forms fixed pivot, and the other end is connected with axle center bar (9), forms moving fulcrum.Arrangement for adjusting height comprises positioning seat (2), fixed mount (3), locator card (4), pulley (5), control stick (8), axle center bar (9) and connecting rod (10).Control stick (8) two ends curve 90 ° by same direction, fixedly connected with axle center bar (9), and locator card (4) is installed in the both sides of axle center bar (9), and are connected with control stick by connecting rod (10).Pulley (5) is installed in the both sides of axle center bar (9), and positioning seat (2) is close to and is installed under the desktop with fixed mount (3).When locator card (4) breaks away from positioning seat (2), pulley (5) can rotate in fixed mount (3) institute restricted portion, thereby the fulcrum of support (6) connecting axle core bar (9) one ends is moved, change the distance between support (6) two strong points, make support (6) distortion, reach the desk lifting, folding purpose; When locator card (4) put in place in positioning seat (2), pulley (5) rotated and is obstructed, and promptly contacted with desktop (1) as fixing point, and support (6) two strong points distance determines that immediately support (6) promptly formalizes, and table height is promptly determined.The frame part of fixed mount (3), be installed between the locator card (4) and pulley (5) of axle center bar (9) both sides, when desk needed stored collapsed, support (6) shrank, 90 ° of table body upsets, an end of lower floor's hack lever is with fulcrum (7) support table body of desktop one end.

Referring to Fig. 3, Fig. 4, desk both sides locator card (4) under stationary state puts in place in the corresponding lattice in positioning seat (2), as the height of need change desk, control stick (8) pusher can be changeed down, and both sides locator card (4) is given up the throne simultaneously; Push away (drawing) moving axis core bar (9), the both sides pulley is turned to desired location, according to contrary direction shown in Figure 4 the locator card (4) of both sides is put in place simultaneously in another lattice of positioning seat (2) again, promptly finish lifting process.

The desktop of the vertical extension table of utility model can adopt plank, wood-based plate manufacturing; Telescope support can adopt the tubing manufacturing; Pulley can adopt the rigid plastics manufacturing; Axle center bar, control stick can adopt garden steel pole manufacturing; Locator card, connecting rod, positioning seat, fixed mount can adopt steel plate or iron plate to make.
