Description

A kind of Foldable handrail table

Technical field

The utility model relates to handrail table field, is specially a kind of Foldable handrail table.

Background technology

Nowadays seat has become one of furniture of other indispensability of each household in the world, the seat of selling in the market consists of the chair back, chair plate, handrail, sitting function is only provided, for the inconvenient crowd of action has a meal on the seat, reads a book, writes, all needing in front has a shelf, common shelf is all generally all-in-one-piece or external, additionally take up room and use inconvenience, therefore a simple and practical, easy to operate folding shelf is extremely important for seat.

Utility model content

The purpose of this utility model is to provide a kind of Foldable handrail table, to solve the awkward problem of prior art shelf.

In order to achieve the above object, the technical scheme that the utility model adopts is:

A kind of Foldable handrail table, be installed between armed seat two handrails of tool, it is characterized in that: include two outside shelfs, two inner side shelfs, two outside shelfs separately outer side edges respectively by rotating shaft one by one corresponding rotation be installed on seat two handrails inner sides, two inner side shelfs separately outer side edges are corresponding hinged with two outside shelf inner side edges one by one by H type hinge respectively, each outside shelf and form secondary development mechanism by the hinged inner side shelf of H type hinge, on two inner side shelfs, close inner side edge position is separately respectively arranged with buckle, inner side shelf round pin, on the shelf of each inner side, snapped-in position is corresponding with shelf round pin position, inner side on another inner side shelf, and buckle corresponding to position on two inner side shelfs, inner side shelf round pin can be fastened.

Described a kind of Foldable handrail table, is characterized in that: on each handrail, be also respectively arranged with the handrail round pin for buckle snapping on the shelf of inner side.

Described a kind of Foldable handrail table, is characterized in that: two outside shelfs, two inner side shelf width sums equal the distance between armrest.

Described a kind of Foldable handrail table, is characterized in that: described buckle end of thread is provided with open-type hole, and the A/F in open-type hole is less than the diameter of inner side shelf round pin and handrail round pin.

Advantage of the present utility model is: (1) takes up room little, and shelf volume when folded state is very little, does not take User Activity space; (2) easy to use, shelf and chair mounted are integrated, and during use, directly shelf are launched; (3) shelf adopts secondary development mechanism, and after launching, effectively usable floor area is large, and has buckle to fix, and surfacing is firm.

The specific embodiment

As shown in Figure 1-Figure 3.A kind of Foldable handrail table, be installed between armed seat two handrails 5 of tool, include two outside shelfs 11, two inner side shelfs 12, two outside shelfs 11 separately outer side edges respectively by rotating shaft 3 one by one corresponding rotation be installed on seat two handrail 5 inner sides, two inner side shelfs 12 separately outer side edges are corresponding hinged with two outside shelf 11 inner side edges one by one by H type hinge 13 respectively, each outside shelf 11 and form secondary development mechanism by the hinged inner side shelf 12 of H type hinge 13, on two inner side shelfs 12, close inner side edge position is separately respectively arranged with buckle 4, inner side shelf round pin 2, on the shelf of each inner side, buckle 4 positions are corresponding with shelf round pin position 2, inner side on another inner side shelf, and buckle corresponding to position on two inner side shelfs, inner side shelf round pin can be fastened.

On each handrail 5, be also respectively arranged with the handrail round pin 6 for buckle 4 snappings on the shelf 12 of inner side.

Two outside shelfs 11, two inner side shelf 12 width sums equal the distance between armrest 5.

Buckle 4 end of threads are provided with open-type hole, and the A/F in open-type hole is less than the diameter of inner side shelf round pin 2 and handrail round pin 6.

When Foldable handrail table folds, buckle 4 and inner side shelf round pin 2 are thrown off, inner side shelf 12 folds around H type hinge 13 with outside shelf 11, vertical direction is positioned over handrail 5 belows, a pair of buckle 4 openends are buckled in respectively on handrail round pin 6, make the same side secondary development mechanism 1 can not separate voluntarily and rotate; When Foldable handrail table launches, a pair of secondary development mechanism 1 first 3 launches to seat center position around the shaft, then pair of inside shelf 12 launches to seat center around H type hinge 13 respectively again, and then two buckle 4 openends are buckled in respectively on inner side shelf round pin 2.
