Abstract

The utility model discloses an improved structure for a movable table top. The part between a chair and a table board is composed of an overturning seat and a tray which can rotate at the fixed position and preset the range of an included angle. A tandem arrangement hole, a movable notch communicated with the tandem arrangement hole and an inwards concave guide channel are arranged on the overturning seat. The center of the seat surface is also provided with a shaft lever, and a positioning shaft hole matched with the shaft lever is arranged on the tray. The overturning seat is assembled on the frame of the chair in a positioning way, and the tray is assembled on the overturning seat in a positioning way so as to cause the table board fixed to the tray to rotatablely retract and spread and to cause the table board to inwards and outwards move at a presetting distance, which is convenient for a user to come in and go out and provides a proper use distance for the user writing on the table board.

Description

The improvement structure of active desktop

The utility model includes the chair of handrail desktop, refers to a kind of structure that desktop can be closed at the chair side especially.

Known systems comprises No. 77449 interior concealed extension leaf of seat support handrail of Taiwan patent announcement, announces No. 124924 adjustable Zhe and closes table, bulletin and can adjust collapsible tables and chairs, the bulletin of desktop height and angle for No. 115362 and have desktop fold-down seat improvement etc. No. 239951;

In No. 77449 design of wherein announcing, in the armrests one turning 180 table is set, in table by handrail in 180 degree after upright turning over take out, turn down into level for use to side 90 degree again, therefore this design only has the effect that the level use is turned down in taking-up, it is certain that the spacing at table and seat then keeps, so personnel's turnover is subjected to the obstruction of table, and the user that constant spacing is more fat or modest for the bodily form, the distance of desktop can't be adjusted at inconvenience in the actual use of writing or reading.

Announcing No. 124924 is to design the structure that then can adjust the table angle in the assembling of chair one side, the table of this angle adjustable and the spacing at seat are also for fixing, so personnel's turnover is hindered by table also, and the distance of desktop and user's health also can't be cut out and adjust according to user's custom, body, so also inconvenience on using.

Announce No. 115362 and be designed to creation collapsible and adjustment tables adjustable height, tables also launched when this was designed to the chair expansion, tables itself are folding and unfolding or expansion separately, simultaneously tables and the spacing at seat be also for fixing, so personnel's turnover, the suitable use spacing that reaches human body and desktop still do not provide appropriate and suitable improvement.

Announce No. 239951 design then for improving the creation of the stressed inclination of desktop, equally also do not have the desktop of making to horizontally rotate displacement, and make things convenient for personnel to pass in and out and effect that the spacing used can suitably be adjusted.

Therefore, in view of the easy overslaugh personnel turnover of existing design table, and table can't be cut out and the pitch problems of change table and human body according to the different bodies of actual user, the purpose of this utility model: but be to provide a kind of extension leaf of horizontal displacement, and the table level is put when using can displacement make things convenient for personnel to pass in and out; Make desktop can cut out, be accustomed to and arbitrarily move according to each different user's hobby, body simultaneously, to reach optimal service range with the spacing of human body.

For solving above-mentioned task, the solution that the utility model adopts is: stretch in the chair either side and establish a pillar, the overturning seat of turning 90 degree of tandem arrangement one on this pillar is provided with a pilot pin that limits the overturning seat flip angle in pillar, and this pilot pin is based in the movable breach of overturning seat; The overturning seat hypomere has a tandem arrangement hole and is assigned on the pillar with string, offers a movable breach in the side in overturning seat tandem arrangement hole, and the angle of these breach two ora terminalis is to set the angle that overturning seat is thrown, and this breach communicates with the tandem arrangement hole; Be provided with the guide channel of an indent in the epimere seat surface of overturning seat, the seat surface center is provided with the axostylus axostyle of a pedestal table sheet tray tandem arrangement positioning and assembling in addition; The table assembly is in the top of pallet, and the through hole that pallet is provided with more than at least one runs through assembly for the screw of the table that is spirally connected, but be provided with the positioning shaft hole of a sleeve in the overturning seat axostylus axostyle in pallet, the beam barrel one side lower edge of this positioning shaft hole is provided with a limited block that can be embedded at displacement in the overturning seat guide channel so that pallet can be in the displacement clip angular region that the overturning seat guide channel limits horizontal displacement adjust the spacing at table and seat.

After adopting this structure, can reach following effect: 1, structure is simplified, firmly; 2, cost is low, economic benefit is high; 3, personnel pass in and out the seat and can pass table, reach to exempt from table and can be beneficial to turnover; 4, can cut out fat or thin, custom, hobby and random mobile table is regulated the spacing of table and human body according to user's body, readings, Writing distance are reached according to the use that matches of user's oneself requirement and conditionally complete.

Now reach embodiment in conjunction with the accompanying drawings and further describe the utility model.

Fig. 1 is the utility model table combination decomposing schematic representation.

Fig. 2 is that the utility model is implemented illustration.

Fig. 3 is the utility model action schematic diagram.

Fig. 4 is the another action schematic diagram of the utility model.

The architecture advances of the utility model active desktop as shown in Figure 1, 2, stretch in chair 1 any side and to establish a pillar 11, be nested with assembly by this pillar 11 for overturning seat 2, the intrinsic pilot pin 12 of a lateral column body appropriate location spiral shell in pillar 11, utilize the movable breach 21 of the outstanding and overturning seat 2 of this pilot pin 12, reach overturning seat 2 and on pillar 11, can do vertical spending and throw to 90 of level.

But overturning seat 2 body hypomeres are provided with 20 insertings location, tandem arrangement hole and are combined on the pillar 11, offer a breach 21 in its tandem arrangement hole 20 1 sides, and 21 liang of ora terminalis of this breach are 90 degree angles each other, and this breach 21 communicates with tandem arrangement hole 20; Be provided with indent guide channel 23 in overturning seat 2 epimere seat surfaces 22 and set according to a position swing offset, establish an axostylus axostyle 24 in addition with the pallet positioning shaft hole 30 of tandem arrangement in combination table 4 in the central authorities of seat surface 22 for pallet 3 root edge limited blocks 32.

Pallet 3 bodies can be any geometric flat shape, be provided with the axostylus axostyle 24 tandem arrangement positioning and assemblings of a location axis hole 30 in the one end for overturning seat 2, and have through hole 31 more than one at least and run through spiral shell for screws and join table 4, beam barrel 301 root edges one place that other is provided with positioning shaft hole 30 is provided with the limited block 32 that can be embedded in overturning seat 2 guide channels 23 according to the round displacement in position, but make pallet 3 position rotating displacement in the setting angular range that limits, and make the table of being fixed on the pallet 34 can do the displacement of set angle and distance.
