Description

The present invention relates to a chair with a back luggage receiver that can be seated while carrying a scuba diving equipment or a farm sprayer.

There existed patent document 1 as a conventional chair. That is, a pair of parallel support shafts are attached rearward to the seat supported by the support legs, and a slide tube is slidably fitted back and forth on the support shaft, and a back plate is attached to the slide tube. There has been a structure in which a back plate is connected, and a back plate and a back plate, that is, a backrest can be moved and adjusted through the slide tube.

According to Patent Document 1, it can be adjusted back and forth according to the growth or physique of the person sitting on the backrest. However, since the slide tube fitted to the support shaft is slid in the front-rear direction, if it is moved largely backward, the fitting amount with the support shaft is reduced and the support strength of the backrest is reduced. Become. For this reason, when the load carried on the back is heavy, the slide bag is damaged or the back is inadvertently moved backward, resulting in poor safety.

SUMMARY OF THE INVENTION An object of the present invention is to provide a novel back load receiving chair that can be safely supported even if the load is heavy.

The present invention is configured as follows to achieve the above object. In other words, the invention according to claim 1 is provided with a seat at the upper and lower intermediate portions of the pair of side frames that are separated from each other on the left and right sides, and the seat extends backward from the saddle to receive the back luggage. A load receiving seat, and a backrest is provided at the upper portion of the side frame, the backrest is bent rearward so as to substantially correspond to an outline of the load receiving seat, and a space is provided above the load receiving seat by the curved portion. It is a thing.
According to a second aspect of the present invention, the seat is formed by assembling elongated materials in a lattice shape or in a cross beam shape.
According to a third aspect of the present invention, a hook is provided outside the backrest.

In the invention according to claim 1 of the present invention, when sitting on a chair in a state where the load is carried on the back, the lower surface of the load on the back is in contact with the load receiving seat, and the backrest surrounds the rear half circumference of the upper portion of the load. The luggage is stably supported by the chair. In addition, the seated person is supported in a stable posture by the saddle portion.
In addition, since the seat is formed by assembling elongated materials in a lattice shape or a cross-beam shape, the frictional force increases, and even if the luggage such as scuba diving equipment and the clothes of the seated person are wet, it flows down from these. Water droplets pass smoothly through the seat, and the luggage and the occupant will not slide on the seat. Further, since the hook is provided outside the backrest, a small article can be hung on the hook.

Embodiments of the present invention will be described below with reference to the drawings. 1 is a perspective view showing an embodiment of the present invention, and FIG. 2 is a side view showing a use state.

In FIG. 1, reference numeral 1 denotes a luggage receiving chair (hereinafter referred to as “chair”) formed of a metal material such as aluminum. The chair 1 includes a pair of left and right side frames 2, 2, a rear leg 5, a seat 10, and a backrest. 15 is formed as a main part.

The side frames 2 and 2 are spaced apart from each other on the left and right sides, and their lower ends are connected by a cross bar 3 and upper parts are connected by a backrest 15. The rear legs 5 are framed in a rectangular shape by the vertical bars 6 and 6 and the horizontal bars 7 and 7, and the upper ends of the vertical bars 6 and 6 are connected to the upper and lower intermediate portions of the side frames 2 and 2 by the first connecting pins. When P1 and P1 are connected to each other so as to be able to rotate back and forth, and when they are expanded, that is, when they are rotated backward, the side frames 2 and 2 are tilted and supported upright so that the upper side is inclined backward.

The seat 10 has a frame of elongated flat steel plates, a rectangular saddle 11 at the front and a semicircular load receiving seat 12 at the rear, and the side frame 2 on the front side. 2 is connected to the upper and lower intermediate portions of the rear leg 5 via the second connecting pins P2 and P2 so as to be rotatable about the horizontal axis, and when the horizontal portion is made horizontal, It abuts and is held horizontally.

The backrest 15 is formed in a circular arc shape toward the rear, and its left and right ends are connected to the upper ends of the side frames 2 and 2 via third connection pins P3 and P3 so as to be rotatable about a horizontal axis. The backrest 15 is formed of an elongated flat steel plate material, and has an outer back plate 16 that is bent in a U shape in a plan view toward the rear, and an inner curve that is curved in an arc shape in a plan view toward the rear inside the outer back plate 16. A back plate (curved portion) 17 is integrally connected, the inner back plate 17 faces above the load receiving seat 12, and the inner back plate 17 creates a space (a) above the load receiving seat 12. Generated.

On the left and right outer surfaces of the outer back plate 16, hooks 18 and 18 for hanging small items bent in an upward L shape are attached. The hooks 18 and 18 are adapted to be fitted (locked) to the side frames 2 and 2 when the backrest 15 is turned to the front side and folded.

Next, the usage mode of the above embodiment will be described. As shown in FIG. 2, for example, when sitting on the chair 1 while wearing a scuba diving equipment (baggage) 20 such as an air tank or a mask, the air tank 21 of the scuba diving equipment 20 on the back is the scorpio 11. It abuts on the load receiving seat 12 located behind. Further, the upper part of the air tank 21 is fitted into the backrest 15, and the rear half periphery of the upper part of the air tank 21 is surrounded by the backrest 15.

In addition, the seated person (wearer) 22 may sit on the saddle 11 in a stable posture and without being affected by the load of the scuba diving equipment 20 without being influenced by the scuba diving equipment 20. it can. In addition, since the scuba diving equipment 20 is stably supported by the chair 12, the seated person 22 can take a rest by removing the scuba diving equipment 20, and sit on the chair 1 when wearing it. Since it can be mounted, the scuba diving equipment 20 can be mounted with little effort. The present invention can also be applied to a person who carries a farm sprayer or a pest control pump.

It is a perspective view which shows the Example of this invention. It is a side view which shows a use condition.
