Description

The present invention relates to an assembling type seat chair in which a seat surface forming frame and a backrest surface forming frame are connected by a joint member, and a covering member is hung on the seat surface forming frame and the backrest surface forming frame to form a seat surface and a backrest surface. ..

Assembled chairs are often used for outdoor leisure so that people can rest comfortably.

However, a prefabricated chair is basically supported by four legs, and a person's weight is applied to the tips of the four legs. In some cases, the chair may not be installed stably because the legs are wobbling or the tips of the legs are sunk into the ground. In addition, the space inside the tent is small, and in particular, the height is limited, so it is not possible to bring in a chair, so it was not always comfortable to spend a long time in the tent while sitting. ..

For this reason, a prefabricated seat chair that can be widely used for outdoor leisure is required, but the tilt angle of the backrest surface of the seat chair can be adjusted according to the body shape and sitting posture of the seated person. On the other hand, adopting a complicated mechanism for adjusting the angle makes it impossible to store it compactly, making it difficult to carry, and it also takes time to assemble, so you can fully enjoy your leisure time. I can't do this.

Therefore, it is desired to develop an assembling chair that can be easily assembled while being compactly housed and easy to carry while being able to adjust the inclination angle of the backrest surface.

The assembled seat chair of the present invention will be described below with reference to the drawings. However, the present invention is not limited to those exemplified as the embodiment for carrying out. Further, the connection or attachment of the constituent members in the present invention includes not only direct connection but also indirect connection via other members, etc., and is relative to the attachment parts of the two target members. Unless otherwise specified, all of them are included as long as they maintain a substantially constant positional relationship.

The prefabricated seat chair (1) is used to form a base end portion (2a) of a seat surface forming frame (2) extending substantially horizontally to form a seat surface (1a) and a backrest surface (1b). The base end portion (3a) of the backrest surface forming frame (3) extending diagonally upward is connected by a joint member (4), and the seat surface forming frame and the backrest surface forming frame are fixed at a predetermined angle to form a frame. (Fig. 2), the seat surface and the backrest surface are formed by hanging the covering member (9) between the tip portion (2b) of the seat surface forming frame and the tip portion (3b) of the backrest surface forming frame (FIG. 1). ..

The number of seat surface forming frames (2) is usually two because they are arranged on the left and right sides of the seat surface, but it is not always necessary to be two, and it is appropriate depending on the shape of the seat surface forming frame and the size of the seat surface. , You can select the place to place and the required number. Further, since the backrest surface forming frames (3) are usually arranged on the left and right sides of the backrest surface, there are two, but depending on the shape of the backrest surface forming frame and the size of the backrest surface, a place to arrange them and a necessary one are necessary. The number can be selected (Fig. 2).

The seat surface forming frame (2) and the backrest surface forming frame (3) usually use a metal round pipe in order to secure strength while reducing the weight, but the present invention is not necessarily limited to this.

The joint member (4) includes a horizontal socket portion (4a) and an inclined socket portion (4b), and the base end portion (2a) of the seat surface forming frame (2) is inserted into the horizontal socket portion (4a). By inserting the base end portion (3a) of the backrest surface forming frame (3) into the inclined socket portion (4b), the seat surface forming frame and the backrest surface forming frame can be connected and fixed at a predetermined angle. (Fig. 3).

The horizontal socket portion and the inclined socket portion do not necessarily have to have a tubular shape as long as they are provided with a socket for inserting the base end portion of the seat surface forming frame and the base end portion of the backrest surface forming frame, respectively, and any shape. Can be adopted. FIG. 3 shows an example of a joint member (4) in which a horizontal socket portion (4a) and an inclined socket portion (4b) are integrally molded with a mold using a synthetic resin, but such a material and shape are not necessarily adopted. It is not necessary to form the horizontal socket portion (4a) and the inclined socket portion (4b) separately, and the joint member may be formed by connecting them. As shown in FIG. 3, when the joint member is integrally molded with synthetic resin, the strength can be increased by forming a reinforcing plate (5) between the horizontal socket portion (4a) and the inclined socket portion (4b). It is preferable because it improves.

In order to adjust the tilt angle (angle with respect to the horizontal direction) of the backrest surface, the joint member (4) is provided with a plurality of tilt socket portions (4b, 4b') having different tilt angles. FIG. 3 illustrates a joint member (4) provided with two inclined socket portions (4b, 4b') having different inclination angles, but it is also possible to include more inclined socket portions. The tilt angle of the backrest surface can be easily adjusted by inserting the base end portion (3a) of the backrest surface forming frame (3) into any of the tilted socket portions according to the user's preference and usage conditions. ..

In the prefabricated seat chair, the seat surface forming frame (2) and the backrest surface forming frame (3) are extracted from the joint member (4), and the seat surface forming frame (2) and the backrest surface forming frame (3) are further separated. By dividing at approximately the middle position (Fig. 5 (b)), the skeleton can be tidied up in a small folded state (Fig. 5 (a)), but the skeleton can be put together for easy portability and assembly. Each member constituting the skeleton may be connected to each other by a connecting cord (8) having elasticity so that the above can be performed quickly. FIG. 5B shows an example of the means for dividing the seat surface forming frame or the backrest surface forming frame at a substantially intermediate position. A seat surface forming frame or the like is formed of a round pipe, a small diameter round pipe is attached to the tip of one pipe (the pipe on the left side in FIG. 5 (b)), and this small diameter round pipe is attached to the other pipe (Fig. 5 (b)). In), if you insert it into the pipe on the right side), you can connect the left and right pipes, and if you pull it out, you can divide it. An elastic connecting cord is passed through the two pipes to prevent the two pipes from being separated, and the two pipes are provided with an appropriate elastic force so that the two pipes can be easily connected. Is connected.

The connecting cord (8) that connects the joint member and the backrest surface forming frame passes from the bottom of the inclined socket portion (4b) to the inside of the inclined socket portion and is connected to the backrest surface forming frame (3). As a result, in order to pull out the backrest surface forming frame from the inclined socket portion and replace it with another inclined socket portion having a different inclination angle, a connecting passage for moving the connecting cord is required (FIG. 4).

In the joint member (4), the side wall surfaces of the adjacent inclined socket portions (4b, 4b') are cut out in the vertical direction with a width smaller than the diameter of the inclined socket portion, and the adjacent inclined socket portions communicate with each other. The shape is such that (6) is formed.

The continuous passage can be formed by cutting the side wall surface of the inclined socket portion, but if the joint member is made of synthetic resin, it can be formed together with the molding of the joint member by a mold. Suitable for productivity.

FIG. 4 shows a state change when the backrest surface forming frame is replaced with an adjacent inclined socket portion. When the backrest surface forming frame (3) is pulled out from the inclined socket portion (4b) having a large inclination angle (angle with respect to the horizontal direction), the connecting cord (8) is in a stretched state. Since the stretched connecting cord (8) can move to the adjacent inclined socket portion (4b') through the connecting passage (6) (FIG. 4 (b)), the backrest surface forming frame is inclined. It can be easily replaced with an inclined socket part (4b') with a small angle.

By inserting the backrest surface forming frame into the inclined socket portion (4b') having a small inclination angle in this way, it is possible to form an assembling chair with a small inclination angle of the backrest surface (FIG. 6).

The prefabricated seat chair (1) can be attached to the seat surface (1a) by connecting the covering member (9) to the tip portion of the seat surface forming frame (2) and the tip end portion of the backrest surface forming frame (3). The backrest surface (1b) is formed (Fig. 1).

The material and shape of the covering member are not particularly limited as long as they support the human body, such as woven fabrics, non-woven fabrics, nets, cushions molded to fit the human body shape, and all other molded products. Is included in this. Further, the size of the covering member is not limited to a size that one person can sit on, but also includes a size that can lie down or allow a plurality of people to sit at the same time.

As shown in FIG. 7, an upper connecting means (10) and a lower connecting means (11) are provided on the lower surface of the covering member (9), and the upper connecting means (10) is provided with a backrest surface forming frame (3). ) Is connected, and the tip (2a) of the seat surface forming frame (2) is connected to the lower connecting means (11). As the lower connecting means, two lower connecting means (11a, 11b) are arranged vertically according to the provision of two types of inclined socket portions having different inclination angles in the joint member. When the backrest surface forming frame is inserted into the inclined socket portion (4b) where the inclination angle of the joint member is large, the distance between the tip portion of the backrest surface forming frame and the tip portion of the seat surface forming frame becomes short, so that the seating surface The tip of the forming frame is connected to the lower connecting means (11a) arranged above (FIG. 8 (a)). On the other hand, when the backrest surface forming frame is inserted into the inclined socket portion (4b') where the inclination angle of the joint member is small, the distance between the tip portion of the backrest surface forming frame and the tip portion of the seat surface forming frame becomes long. The tip of the seat surface forming frame may be connected to the lower connecting means (11b) arranged below (FIG. 8 (b)). Although FIG. 7 shows an example in which two lower connecting means (11a, 11b) are provided at different positions in the longitudinal direction of the covering member, two upper connecting means are provided instead of the lower connecting means. May be good.

As described above, the lower surface of the covering member is provided with a lower connecting means for connecting the tip end portion of the seat surface forming frame and an upper connecting means for connecting the tip end portion of the backrest surface forming frame. By arranging a plurality of lower connecting means or upper connecting means at different positions in the longitudinal direction, the inclination angle of the backrest surface can be easily adjusted.

As shown in FIG. 7, the lower connecting means or the upper connecting means can be formed by sewing a cloth on the lower surface of the covering member to form a bag or pocket-like shape, but a material such as plastic or metal is seated. A molded product molded so that the tip end portion of the surface forming frame or the backrest surface forming frame can be inserted may be attached to the lower surface of the covering member. Further, a hole having a predetermined size may be provided in the covering member, and a tip portion such as a seat surface forming frame may be inserted and connected. Even if the tip of the seat surface forming frame or the like is simply inserted into such a lower connecting means or the like, it will not easily come off during use due to the tension of the covering member and the weight of the covering member. The material and shape of the lower connecting means or the upper connecting means are not limited as long as they are for connecting the tip end portion of the seat surface forming frame or the backrest surface forming frame to the lower surface of the covering member.

Usually, the seat surface forming frames are arranged on the left and right sides of the seat surface, and the backrest surface forming frames are arranged on the left and right sides of the backrest surface. Therefore, by connecting the two left and right joint members (4, 7) that connect the seat surface forming frame and the backrest surface forming frame with the connecting frame (12), the strength of the prefabricated seat chair can be dramatically improved. Can be done. If the two left and right joint members (4, 7) are provided with connecting sockets (4c, 7c) for inserting both ends of the connecting frame (12) extending in a substantially horizontal direction on the opposite side surfaces, the two left and right joint members (4, 7) are provided. The joint members can be connected via the connecting frame (Fig. 2). The connection between the joint member and the connecting frame does not necessarily have to be detachable, and may be adhesively fixed.

The prefabricated chair is usually installed on the ground or on a seat laid on the ground, but the prefabricated chair can be placed on a table or the leg members can be placed under the prefabricated chair. Once attached, you can sit down like a normal chair. In addition, if the prefabricated chair is installed on a chair without a backrest, it is possible to sit on the back as if it were a chair with a backrest.
