Abstract

The utility model discloses a foldable writing chair, comprising a seat plate (2), foldable supporting feet (1), a table surface plate (4), a vertical plate (3), an upper supporting plate (5) and a lower supporting plate (6). The lower edge of the vertical plate is hinged with the front edge of the seat plate, and the upper edge of the vertical plate is hinged with the back part of the lower surface of the table surface plate. The upper end of the upper supporting plate (5) is hinged with the front part of the lower surface of the table surface plate, the lower end of the upper supporting plate is hinged with the upper end of the lower supporting plate, and the lower end of the lower supporting plate is hinged with the lower part of the vertical plate. When the vertical plate is unfolded, the vertical plate is vertical with the seat plate. When the table surface plate is unfolded, the table surface plate and the vertical plate are supported by the upper supporting plate and the lower supporting plate. The table surface plate is extended onwards, the table surface plate is vertical with the vertical plate and parallel with the seat plate. The table surface plate is higher than the seat plate and is extended onwards, the user can ride on the seat plate, and both hands can lie against the table surface plate to write. When the foldable writing chair is folded, the table surface plate and the seat plate are abutted together, and the supporting feet are folded under the seat plate. The utility model has the advantages of small volume and easy carrying and storage.

Description

Collapsible writing chair

Technical field

The utility model relates to a kind of structure of portable chair, a kind of collapsible writing chair.

Background technology

Folding chair is to be easy to carry after folding.Existing faldstool comprises seat and four folding feets, and feet is under the seat, becomes oblique criss-cross construction, and seat is play supporting role, and wherein the upper end of a pair of feet reaches the seat top, becomes the chair back.Use this class faldstool, when writing, need use other apparatus of desk and so on simultaneously.

Summary of the invention

The utility model is intended to propose a kind ofly both can sit, the folding seat that can write thereon again simultaneously, a kind of collapsible writing chair.

This collapsible writing chair comprises seat, collapsible feet and deck plate.Feet be installed in seat below.It also comprises riser, upper supporting plate and lower carrier plate.The lower limb of riser and the leading edge of seat are hinged, and the rear portion of the top edge of riser and deck plate lower surface is hinged.The front portion of the upper end of upper supporting plate and deck plate lower surface is hinged, and the lower end of upper supporting plate and the upper end of lower carrier plate are hinged, and the lower end of lower carrier plate and the bottom of riser are hinged.When riser was opened, riser and seat were perpendicular.When deck plate is opened, supported by upper supporting plate and lower carrier plate between deck plate and the riser, deck plate stretches out forward, and deck plate and riser are perpendicular, and deck plate parallels with seat.

After this collapsible writing chair is opened, rely on the support of riser, upper supporting plate and lower carrier plate, make deck plate exceed seat and also stretch out forward, the user can ride on the seat, and both hands lean against on the deck plate and write.When this collapsible writing chair closed up, deck plate and seat fit together, and feet draws under the seat, and volume is very little, and is easy to carry and store.

The specific embodiment

As shown in Figure 1, this collapsible writing chair comprises seat 2, collapsible feet 1 and deck plate 4.Feet be installed in seat below, the structure of feet is identical with folding seat commonly used, is oblique criss-cross construction, wherein the last fulcrum of a pair of feet can be along the lower surface slip of seat, feet is strutted or closes up.It also comprises riser 3, upper supporting plate 5 and lower carrier plate 6.The leading edge 11 of the lower limb of riser 3 and seat 2 is hinged, the rear portion of the top edge of riser and deck plate 4 lower surfaces is hinged, the front portion of the upper end of upper supporting plate 5 and deck plate lower surface is hinged, the upper end of the lower end of upper supporting plate and lower carrier plate 6 is hinged, and the lower end of lower carrier plate 6 and the bottom of riser are hinged.When riser 3 was opened, riser was upwards holded up, and riser and seat 2 are perpendicular.When deck plate 4 was opened, deck plate stretched out forward, and is perpendicular with riser, parallels with seat, supported by upper supporting plate, lower carrier plate between deck plate and the riser.The user can ride in forward on the seat 2, and both hands lean against on the deck plate 4 and write.

As shown in Figure 3, when this collapsible writing chair closed up, deck plate 4 collapsed to riser 3, collapse to seat 2 together with riser, deck plate 4 fits together with seat 2 again, and feet 1 draws under the seat, in the groove under the embedding of feet shown in the figure seat, volume is very little.Carry and use all very convenient.

As Fig. 4, illustrated in figures 1 and 2, can there be a depressed portions 8 at the middle part of the lower surface of the deck plate 4 of this collapsible writing chair, and when deck plate and riser 3 were superimposed, riser embedded in the above-mentioned depressed portions 8 of deck plate.Described riser 3 has a groove 7 with lower carrier plate 6 places of being hinged, in the above-mentioned groove 7 on upper supporting plate 5 and the lower carrier plate 6 folding back embedding risers.When such structure can make deck plate collapse, be close together (as shown in phantom in Figure 1), at this moment, open feet 1, can be used as faldstool and use with seat.Close up and riser when being opened up to plumbness at deck plate 4 and riser 3, deck plate and riser also can be used as backrest and use.

As shown in Figure 2, when the upper supporting plate 5 of this collapsible writing chair and lower carrier plate 6 were opened, the angle (being the β angle) of its top should be less than 180 degree.Like this, can make total be in stable state, deck plate collapses automatically at the upper surface Shi Buhui that is under pressure.

As shown in Figure 1, can also there be a magnetic head 9 at the rear portion of seat upper surface, as shown in Figure 2, there is a soft iron 10 at the rear portion of deck plate lower surface, when deck plate and seat fit together, above-mentioned magnetic head is pulled together mutually with soft iron, and deck plate and seat are pulled together, and can not scatter automatically.A hasp 12 can also be arranged at the bottom of riser 3, matches with a little hook 13 on the deck plate lower surface, and when deck plate collapsed, above-mentioned hasp of riser and deck plate and little fastener lumped together.
