Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a folding chair, and more particularly to a folding chair that can be stacked high despite having armrests.

[Conventional technology]

Folding chairs are generally used as chairs for an unspecified number of people because they do not require a large area for storage and are convenient to carry.

The most widely used folding chair is one that is constructed by combining pipes, etc., as is well known, and its structure is roughly explained as shown in Fig. 8, with front legs 22 and rear legs 23 placed at point A. in,
Connect the rear legs 23 and the seat plate 21 at point B, then connect the seat plate 21 and the front legs 22.
are rotatably attached at points C and D via an auxiliary arm 24, and the seat plate 21
When the tip of the rear leg 23 is tilted toward the backrest 25, that is, in the X direction, the rear leg 23 rotates in the Y direction and can be easily folded. When folded, they are almost flat and can be stacked up to a certain height.

[Problem that the invention attempts to solve]

This type of general-purpose folding chair has the disadvantage that it easily collapses if stacked high when putting it away, and when in use, it has no armrests, making it difficult for the person sitting on the chair to maintain an upright posture, resulting in a lack of comfort. It was hot. On the other hand, when it comes to folding chairs with armrests, there are not many commercially available products.
Furthermore, it can be said that there are no chairs that have been put to practical use that are suitable for stacking them high. This has problems such as the armrests getting in the way of efficiently tidying up and tidying up in a narrow storage space, and the advantage of folding being lost, or the method of folding becoming more complicated, which has not yet been resolved. This is thought to be due to the fact that the

This invention was devised to solve the above problems, and its purpose is to not only fold it easily despite having armrests, but also to be able to stack it efficiently and to stack it high. To provide a folding chair with armrests that does not collapse even when folded.

[Means for Solving the Problems] The folding chair of the present invention has a front leg and a rear leg on both sides of the seat plate, and an armrest that connects the backrest to the front leg. At the same time, the rear legs are bent at an angle equal to the angle formed by the front legs and the armrest, and the rear legs are rotatably attached to the rear of the armrest. , and the bending corner is attached so that when the rear leg is rotated toward the front leg, the bent corner comes into contact with the joint between the front leg and the armrest.

The folding chair of the present invention consists of a seat board, front legs, back legs, a backrest, and armrests. The front legs and the hind legs are provided on each side of the seat plate. The backrest, armrests, and front legs are integrally formed as one part or by joining each member, and are connected from the backrest to the front legs via the armrests.

Further, the seat plate is attached to the front legs so as to be slidable primarily in the front-rear direction, and is attached to the rear legs so as to be rotatable.

In addition, the rear legs have a shape bent at an angle equal to the angle formed by the front legs and the armrest, and are rotatable at the rear of the armrest, and when the rear legs are rotated toward the front legs, the bent angle portion is attached so as to be in contact with the joint between the front leg and the armrest.

In order to slidably attach the seat plate to the front legs, for example, a slide groove or a rail may be provided on the side surface of the seat plate, and a pin or the like that is slidably engaged with the slide groove or rail may be fixed to the front legs.

To rotatably attach the seat plate to the rear legs, or the rear legs to the rear of the armrest, for example, you can attach them pivotably by providing a recess on one side and a protrusion on the other, or you can attach them pivotably using bolts, caulking, rivets, etc. , or it may be hinged.

[Effect]

With the above configuration, neither the seat plate nor the rear legs are fixed to the front legs or armrests, and when the seat plate is slid forward or the rear legs are rotated forward, the bending of the rear legs The chair can be folded in such a way that the corners touch the joints between the front legs and the armrests. Since the front legs face downward relative to the nearly horizontal armrests, and the backrest faces upward relative to the armrests, the shape of the chair when viewed from the side when folded is generally wavy. By using the waveform, it is possible to stack multiple chairs without causing any displacement in the front-back direction. Furthermore, since the seat boards can be stacked while being sandwiched between the left and right legs of other chairs, there will be no misalignment in the left and right directions. Since the chairs stacked in this way cannot move relative to each other, they will not collapse even if they are stacked high.

〔Example〕

Embodiments of the folding chair of the present invention will be described below with reference to the drawings.

Embodiment 1 FIGS. 1, 2, and 3 show a folding chair according to one embodiment, and are respectively a perspective view, a side view, and a rear view. This chair is a chair with a backrest 7 and armrests 4. The fixed part 6 of the back plate 5, the armrest 4, and the front leg 2 are integrated, and the rear leg 3 is attached to the armrest 4.
It is rotatably attached to a connecting portion 8 formed at the rear of the body using a bolt 9. A protrusion 14 is formed on the armrest 4, and a protrusion 13 is formed on the rear leg 3. As can be seen from Figures 1 and 2,
The hind legs 3 are bent, and the bending angle is the armrest 4.
It is equal to the angle formed by the front and back 2.

Long oval holes 11 are bored on both sides of the seat plate 1,
A support shaft 12 passing through the hole 11 is fixed to the left and right front legs 2, 2 so as to span horizontally between the left and right front legs 2, 2 (FIG. 3). That is, the seat plate 1 is slidably attached to the front leg 2. In addition, long oval hole 1
1 has a locking groove 11a formed in its front part, and when the chair is in use, the locking groove 11a and the support shaft 1
2, the seat plate 1 is temporarily fixed.

Further, the seat plate 1 is attached to the rear leg 3 by bolts 10 so as to be rotatable relative to the rear leg 3.

Therefore, this chair is changed from the state shown in Fig. 2 to seat plate 1.
After lifting the tip end of the support shaft 12 upward and removing the support shaft 12 from the locking groove 11a, for example, as shown in FIG.
can be sequentially moved as shown by a dashed line, a dashed double dot line, and a solid line, and finally folded into the state shown in FIG.

The folded chairs can be stacked as shown in FIG. The protrusions 13 and protrusions 14 serve to stack the chairs directly on top of each other. Since the chairs are stacked with their corners aligned using the bent shape of the chairs, there will be no misalignment in the front-rear direction. In addition, since the seat board 1 is stacked up between the left and right legs of other chairs, no misalignment occurs in the left and right directions.
Therefore, this chair will not collapse even if it is stacked high.

Embodiment 2 The chair of this embodiment is obtained by removing the convex portion 13 and the protruding portion 14 from the chair of Embodiment 1 shown in FIGS. 1 to 6. Even such chairs can be stacked high by using a stand 16 placed on the floor 15, for example, as shown in FIG.

The folding chair of the present invention is not limited to the above-mentioned embodiments, and any modifications and changes may be made without departing from the purpose, structure, and effects of the present invention. For example, although the front legs, rear legs, armrests, etc. are illustrated as if they were made of square pillars, they may be made of cylindrical pipes or the like, and there is no limit to the uniformity of the thickness. In addition, from the viewpoint of comfort and design, each leg, armrest, seat plate, backrest, etc. may of course be made into a curved shape as long as it does not interfere with stacking, and the backrest may be made to be tiltable. You are also free to do so.

[Effect of idea]

The folding chair of the present invention has a seat plate slidably attached to the front legs and rotatable to the rear legs, the rear legs bent at an angle equal to the angle formed by the front legs and the armrest, and The rear legs can be rotated to the rear of the armrest, and when the rear legs are rotated toward the front legs, the bending corner is attached to the joint between the front legs and the armrest, making operation very easy. It became possible to fold the chair, and as mentioned above, the shape of the folded chair became suitable for stacking. Therefore, even though the chairs have armrests, it is now possible to stack the folding chairs high without causing any displacement in either the front/back or left/right directions, and therefore without the risk of them collapsing.

In other words, the present invention provides a chair that combines the convenience of a folding chair and the comfort of an armchair, which was said to be difficult to achieve in the past, and can greatly contribute to improving the functionality of chairs. The day came.
