Description

Detailed Description of the Invention

[0001]

An object of the present invention is to prevent the backrest from dripping and being restricted in the direction of sitting, which is often used as a simple chair for a dining room, a counter chair, a simple chair for school children, or the like. The present invention relates to a chair with a legrest that allows the user to sit down with his or her legs in a sitting position. In particular, it has a structure that can withstand rough handling and stores multiple chairs in a stack. It is intended to provide a chair with a legrest having an improved structure that enables the above.

[0002]

2. Description of the Related Art As one of the chairs having a simple structure generally used as a simple chair for a dining room, a counter chair, a simple chair for school children, etc., a disk is mounted on a steel pipe leg called a round chair. There is a round seat attached with the above-mentioned round chair, the ends of two legs formed by bending an iron pipe into a substantially inverted U shape are grounded, and crossed in a cruciform shape in plan view. It is connected to the lower surface of the seat plate by tapping screws or the like, and there is a seat plate provided with a cushion cover or the like as appropriate. This type of round chair is lightweight and inexpensive, has a small occupied area when used, has no direction when used, and is a chair that can be stacked and stored and managed easily. It is suitable as a chair that can be used for a short period of time, such as a chair or a chair for school children, and it has been used in large quantities.

These conventional round chairs have the above-mentioned advantages, but on the other hand, since the legs are composed of only four pipes, they are used with an excessive load or with the legs slanted. If this happens, the lower part of the leg part may expand or bend inward, and eventually it may not be able to withstand sitting and function as a chair. Especially, it should be adopted as a chair for school children. In this case, since the children's curiosity causes them to be handled unexpectedly and break easily, there is a demand for further improvement in strength. There has also been proposed a method in which an annular member is screwed or welded directly to the inside or outside of the leg to prevent individual legs from deforming independently. The part is just a contact However, not only does it not have sufficient strength, but screwed ones may easily be removed by children's mischief, so they do not always meet the demand. I can't store it,
There was also the problem that the storability was impaired.

Further, in this round chair, in order to simplify the structure as much as possible and to enable stacking and storing, the backrest and the footrest portion at the time of sitting (the above-mentioned reinforcing annular member cannot be used for the footrest portion). Since the strength is insufficient and the mounting position does not assume a footrest, the conventional one does not fulfill the footrest function.) It has a structure that omits it, especially when it is used for school children etc. For children of different heights, it may be difficult for the children to have a stable sitting posture, and after all, it is possible for children who have difficulty keeping a fixed posture for a short time to have a desired posture. It is a fact that even in the case of a round chair, the footrests have been regarded as necessary because it is necessary to keep such consideration.

In view of the present situation of such a round chair, the present inventor set out to develop and study a chair with a footrest capable of increasing the rigidity of legs without impairing the structure capable of stacking and storing, As a result of repeated trial and error and numerous experiments over a long period of time, we succeeded in developing and realizing a new chair with a footrest that has a completely new footrest structure that can finally achieve the intended purpose. In the following, the configuration will be described in detail together with the embodiments representative of the present invention shown in the drawings.

[0008]

As clearly understood from the embodiments of the present invention shown in the drawings, a chair with a footrest included in the present invention basically has the following structure. That is, the leg member, which is arranged in a well-balanced manner with respect to the seat plate, is fixed to the seat plate by restricting most of the entire length of the upper side from the lower end in the plane arrangement so as to be located outside the peripheral edge of the seat plate. , A strong supporting member of a predetermined length is provided on an outer portion of the leg member located at a predetermined height position from the lower end thereof.
Each of the base end sides is embedded in the leg member, and the tip end side is projected and formed in a cross structure with the outer side directed so as to be integrated.
The supporting members protruding from the outside of the leg members are attached in a substantially horizontal shape by a structure in which all or a part of the supporting members are exposed and left, and are integrated so that each leg member has a predetermined position. A chair with a footrest in which an annular footrest member is arranged and fixed at a portion spaced from the outer surface.

Furthermore, the basic structure of the chair with a footrest according to the present invention described above will be shown by other expressions. The leg members arranged in a well-balanced manner with respect to the seat plate are arranged from the lower end to the upper side in a plane arrangement. Is fixed to the back side of the seat plate while controlling most of the entire length of the seat plate to be located outside the periphery of the seat plate.
At the outer portions of the leg members at predetermined heights from the lower ends, strong supporting members of a predetermined length are provided so as to project in a crossed structure with the base end side penetrating the leg member and the tip end side facing outward. , A structure in which, in addition to being integrated, an annular footrest member is provided on each tip side of the supporting members so that all or a part of the supporting members protruding from the outside of the leg member are exposed and left. By attaching and integrating them in a substantially horizontal manner, an annular footrest member is arranged and fixed at a portion at a certain distance from the outer surface of each leg member at a predetermined position. It will be a characteristic chair with legs.

The leg member is made of a material such as a metal tube or rod having sufficient strength and is easy to mold, and in order to further reduce the weight, for example, an aluminum alloy or stainless steel, or It is also possible to use a synthetic resin molded product or the like in which glass fibers are mixed. In addition, these leg members are bent in an inverted U shape and
A set or more sets should be combined in a well-balanced manner on the plane arrangement, and the leg members shall consist of an even number such as 4, 6, etc., for example, 3 or 5 leg members forming an inverted L shape. It is also possible to provide a stand-alone chair with an odd number of legs, such as three legs, by combining an odd number of legs, etc., and the legs of the leg members have a restricted mounting relationship with a seat plate described later. Must be integrated in this way.

At the lower end portion of the leg member, which comes into contact with the floor, a floor surface protection member for preventing the floor surface from being scratched, for example, soft rubber such as natural rubber, synthetic rubber, or plastic is used. It is assumed that the cushioning material such as cork, non-woven fabric, sponge, rubber, etc. is fitted only to the part that is formed by the contact with the floor surface, and it has been generally adopted for conventional chairs. It is also possible to attach the casters that are installed.When using these casters, cushioning materials such as synthetic resin and rubber covers are used for the rolling surface of the wheels to protect the floor surface as much as possible. Should.

The seat plate is made of a material and shape that can be stably supported by receiving the hips of the user. The seat plate has a flat and simple circular shape like a conventional round chair, and a square shape. Of course, it is also possible to use polygonal shapes such as pentagons or appropriately planar shapes such as elliptical shapes and star shapes. In addition, the whole material is a single material such as wood, metal, plastics, or It may be formed in the same manner as a conventional seat plate, such as a composite material in which they are appropriately laminated and combined, or a surface thereof is covered with a covering material together with a cushion material.

The leg members described above are not only arranged in a well-balanced manner on the plane of the seat plate, but are also attached to and integrated with most of the upper side of the leg member leg, that is, the seat plate. The part that is not directly engaged with must be installed in such a layout that all the cross-sections of the members that make up the legs are located outside the contour of the seat plate, and as a result, the seat plate is According to the present invention, it is possible to realize a structure that can be inserted and stacked between the legs from the bottom of another chair. It should be noted that it is also possible to appropriately adopt a structure in which the leg member is integrated with the seat plate by a shaft structure that is rotatably supported so that the seating direction can be freely changed.

The supporting member has an annular footrest member, which will be described later, attached to each leg portion of the leg member to realize an integrated structure. A strong integrated structure is realized, and it has a function of supporting the load applied to the annular footrest member supported at the distal end side together with the leg member leg portion, and preferably, the base end side edge thereof is the leg member. Even if it is embedded in the leg, it should not be exposed to the outside, and should be formed as a structure that stops within the member cross section of the leg, but from the viewpoint of manufacturing processing, it penetrates completely across the leg. Alternatively, it is also possible to properly polish and paint the portion that penetrates and is exposed from the leg portion to finally prepare the appearance. Therefore,
The attachment structure for the legs of the support member includes not only the embedding structure but also the penetrating structure.

The supporting members are tubular bodies each having a smaller cross section (when the supporting member is a tubular body or a rod-shaped body) or a thin cross section (when the supporting member is a plate body) than the cross section of the member forming the leg portion,
A rod-shaped or plate-shaped member having strong strength, for example, a steel pipe or a cut steel plate, or a synthetic resin pipe or plate such as engineering plastic (industrial plastics), for embedding or penetrating the legs The crossing angle of is to be substantially horizontal or slightly inclined so that the tip side faces upward.

The annular footrest member is supported by the support member in a substantially horizontal manner on the outside of a predetermined height position (for example, a height position of about 50 to 150 mm) from the lower end of the leg portion. In order to provide sufficient strength, a firm attachment structure for the support member, for example, the tip side of the support member, as disclosed in the examples described later, is used to maintain the posture. A structure in which the member is embedded and welded or screwed, or a bifurcated mounting plate is provided in advance on the side of the annular footrest member, and the mounting plate is crowned or attached to the tip side of the supporting member. It should be attached by welding, screwed structure, etc. Incidentally, the annular footrest member is not particularly limited as long as it can be expected to have sufficient strength, and the material is not used as it is or is appropriately applied by coating, etc., and a projection is appropriately provided on the material surface, It should be used to stimulate the soles of the feet to promote health, and to combine additional functional members such as magnets and things that are expected to have far-infrared effects to improve blood circulation on the soles of the feet. You can also

The arrangement relationship of the annular footrest member with respect to the leg member is such that, in the attachment structure with the supporting member, the supporting member is not hidden at all, that is, the portion embedded in the leg portion, and the annular member. Except for the portion attached to the footrest member, the exposed portion of the support member itself is about 10 to 40 mm (desirable when the chair is assumed to be handled roughly like in the case of school children). Is 1
It should be around 0 mm, and care should be taken so that the load on the supporting member does not become too large. ) The arrangement relationship is such that it is secured so that the inside of the annular footrest member does not directly contact the outside of the leg portion, and the arrangement relationship is such that it is floated from the leg portion by the support member. It must be.

Claims (5)

[Claims] 1. A leg member, which is arranged in a well-balanced manner with respect to a seat plate, is regulated so that a large portion of the entire length of the leg portion from the lower end on the free end side to the upper side is located outside the peripheral edge of the seat plate in a planar arrangement. And fixed to the seat plate, and at the outer portions at the predetermined height positions from the lower ends of the legs, strong supporting members of a predetermined length are embedded in the legs at their base ends, respectively. All of the supporting members in which annular footrest members are protruded from the outside of the legs are provided so as to project and be integrated with a crossing structure with the tip end facing outward. Or, by attaching and integrating them in a substantially horizontal shape with a structure in which a part of them is exposed and left, an annular foot-hanging member is provided at a portion spaced from the outer surface of each leg part at a predetermined position. A chair with a footrest, which is arranged and fixed. 2. A leg member, which is arranged in a well-balanced manner with respect to a seat plate, is regulated so that, in a plane arrangement, most of the entire length of the leg portion from the lower end on the free end side to the upper side is located outside the periphery of the seat plate. Then, while being fixed to the back surface of the seat plate, a supporting member having a predetermined length and a strong strength is provided at the outer portions at the predetermined height positions from the lower ends of these leg portions, the base end side of which is passed through the leg portions, All of the supporting members in which annular footrest members are protruded from the outside of the legs are provided so as to project and be integrated with a crossing structure with the tip end facing outward. Or, by attaching and integrating them in a substantially horizontal shape with a structure in which a part of them is exposed and left, an annular foot-hanging member is provided at a portion spaced from the outer surface of each leg part at a predetermined position. A chair with a footrest, which is arranged and fixed. 3. The leg member, which is arranged in a well-balanced manner with respect to the seat plate, is regulated so that, in plan view, most of the entire leg length from the lower end on the free end side to the upper side is located outside the peripheral edge of the seat plate. And fixed to the back side of the seat plate, and strong supporting members of a predetermined length are formed on the outer portions of the legs at a predetermined height from the lower ends of the legs, with their base ends embedded in the legs. In addition, the front end side is projected and formed as an integral structure in a crossover structure in which the front end side is directed obliquely upward to the outside. On the front end side of each of the support members, an annular footrest member is protruded from the outside of the leg portion. The supporting member is attached in a substantially horizontal shape with a structure in which all or part of the supporting member is exposed and left so that the supporting member can be attached to a portion at a certain distance from the outer surface of each leg at a predetermined position. Feet in which an annular footrest member is arranged and fixed Chair with a hanging. 4. The leg member, which is arranged in a well-balanced manner with respect to the seat plate, is regulated so that, in a plane arrangement, most of the entire length of the leg portion from the lower end on the free end side to the upper side is located outside the peripheral edge of the seat plate. And fixed to the back side of the seat plate, and strong supporting members of a predetermined length are formed on the outer portions of the legs at a predetermined height from the lower ends of the legs, with their base ends embedded in the legs. Then, the tip side is projected in a cross structure in which the tip side is directed obliquely upward to the outside so as to be integrated, and each tip side of these support members is inserted in the axial center of the annular footrest member in a cross shape,
With a structure in which all or part of the supporting member protruding from the outside of the leg is restricted so as to remain exposed, the annular footrest member is attached to the supporting member in a substantially horizontal shape, and is integrated. A chair with a footrest, wherein an annular footrest member is arranged and fixed to a portion of each leg member at a predetermined position from the outer surface of the leg member. 5. A tubular portion of a floor surface protecting member, wherein a leg member is formed by bending a steel pipe, and a felt is integrated on a lower surface with respect to a hollow portion opened at a lower end on a free end side of the leg portion. The chair with a footrest according to any one of claims 1 to 4, wherein the chair is press-fitted and fixed.
