Conventionally, furniture with a top plate such as a table or desk and furniture such as chairs have been widely used in offices and homes. In these furniture, various furniture members that can play a required role as furniture while molding metal pillar materials such as the legs of furniture with a top plate, leg columns of chairs, and leg blades into a desired shape are proposed. Has been done. In many cases, a metal material is applied to such furniture members. As for these metal materials, many have been proposed in which a solid metal material is machined to form a solid metal material in order to effectively maintain the strength, or a material cast into a required shape.

Further, for the purpose of reducing the weight or simplifying the structure of the furniture member, for example, a pipe material having substantially the same cross-sectional view manufactured by extrusion molding is appropriately bent to be suitably applied as a furniture member. The obtained technique has also been proposed (see, for example, Patent Document 1).

Japanese Patent No. 3179384

When the pipe-shaped member is bent at a right angle by the technique described in Patent Document 1, problems such as unnecessary dents and cracks in the material are effectively solved.

However, as a member for forming furniture, not only the material is bent at a required angle, but also the entire outer shape is formed into a required shape such as a tapered shape, or another member is attached to an end portion. Various types of processing are required, such as pre-processing into an easy-to-use shape.

Here, in order to form a pipe-shaped material into a required shape, it is conceivable to excavate the surface or weld other materials, and if these measures are used, of course, based on the pipe-shaped material. Can also be molded into the required shape. However, if such a method is applied, the number of steps for molding each piece of furniture will increase, additional materials will be required, and as a result, the manufacturing cost will increase. It causes a malfunction.

At present, there is a demand for furniture members that have both productivity and ease of molding into a required shape with high efficiency while applying pipe-shaped members as furniture members.

That is, an object of the present invention is to solve the above-mentioned problems, and for furniture having a suitable shape while maintaining high efficiency and productivity while using a material having a cross-sectional view pipe shape. It is an object of the present invention to provide a member and furniture provided with the member for furniture.

The present invention has taken the following measures in order to achieve such an object.

That is, the furniture member according to the present invention has a concave surface having a shape recessed from any one direction with respect to a material forming a cross-sectional view pipe, an opposing surface provided on the side facing the concave surface, and a longitudinal direction. a proximal end which forms one end, without the opposite side in the longitudinal direction to the proximal end; and a cross-sectional shape different from the tip portion and said proximal portion, said concave surface is most to the facing surface An inwardly inclined surface that is close to the facing surface and is inclined at a predetermined inward inclination angle, and both sides of the inwardly inclined surface are most distant from the facing surface and are inclined at a predetermined outwardly inclined angle with respect to the facing surface. It has an outer inclined surface, and the inner inclined angle is set to be larger than the outer inclined angle .

In such a case, by applying a material having a cross-sectional view pipe shape and molding it into an appropriate shape, a material having a cross-sectional view pipe shape is formed in the same manner as a member formed like a solid machined member. It is possible to provide a furniture member having a suitable shape while maintaining high efficiency and productivity, and a furniture provided with the furniture member.

It said concave surface has a clearance region which forms a dimension of more than the thickness dimension of the material provided on both sides of said inclined surface, said outer inclined surface, by being placed in this clearance region, the present invention The furniture member according to the above can be used for various purposes.

Further, in order to make the appearance of the furniture member more suitable and to have a shape that does not easily interfere with the user's feet, the tip portion is formed into a substantially circular or elliptical cross-sectional shape and is formed on the floor surface. It is desirable that a grounding member for grounding can be attached.

Then, in order to suitably form the concave surface without damaging the member forming the cross-sectional view pipe shape, it is desirable that the clearance region is configured to have a dimension of three times or more the thickness dimension of the material.

Then, in order to form the furniture member itself into a required shape while effectively maintaining the apparent thickness dimension, the concave surface is pressed against the surface of the pipe-shaped material on the short side in cross-sectional view. It is desirable to configure by.

As shown in FIG. 1, the furniture T with a top plate, which is the furniture of the present embodiment, has a leg body 1 which is a furniture member and, for example, an L-shape in a plan view supported by the leg body 1 via a support frame T1. It is mainly composed of the eggplant top plate T2.

In the present embodiment, the leg body 1 has a tip portion 16 to which an adjuster A, which is a grounding member for grounding the floor surface, can be attached to the lower end side, and a top plate T2, which is a component for forming furniture, downward. It has a base end portion 15 having a support mounting portion 15a for supporting from.

The leg body 1, which is a member for furniture according to the present embodiment, is provided with a concave surface 11 having a shape recessed from an arbitrary direction with respect to a material forming a pipe-like cross-sectional view, and a side facing the concave surface 11. For furniture including a facing surface 12, a base end portion 15 forming one end side in the longitudinal direction, and a tip end portion 16 having the base end portion 15 on the opposite side in the longitudinal direction and having a cross-sectional shape different from that of the base end portion 15. A member, the concave surface 11 is provided on both sides of the inner inclined surface 11a, which is closest to the facing surface 12 and is inclined at a predetermined inward inclination angle inclined from the facing surface 12, and the material. It has a clearance region 11c having a size equal to or larger than the thickness dimension, and an outer inclined surface 11b that is most distant from the facing surface 12 in the clearance region 11c and is inclined at a predetermined outer inclination angle inclined from the facing surface 12. It is characterized in that the inward inclination angle is set larger than the outer inclination angle.

Hereinafter, a specific configuration of the leg body 1 will be described.

The leg body 1 is made of, for example, a pipe-shaped steel pipe. Specifically, it is formed into a tubular shape by rolling a steel sheet and welding the ends to each other. Of course, as a material that can form the leg body 1, an extruded aluminum material may be applied in addition to the above steel pipe.

Further, in addition to the base end portion 15 and the tip end portion 16, the leg body 1 has a concave surface 11 formed by denting a material over substantially the entire area of one surface in the longitudinal direction, a facing surface 12 facing the concave surface 11, and these. It has a side surface 13 interposed between the concave surface 11 and the facing surface 12, and a bent portion 14 bent in the longitudinal direction. Further, in the present embodiment, the bent portion 14 has a shape in which a part of the side view is bent, but of course, a part may be curved instead of bent, and further, the bent portion 14 may be shaped as a whole. ..

As shown in FIGS. 4 and 7 to 9, the concave surface 11 is formed by pressing the surface of the pipe-shaped material on the short side in cross-sectional view. The concave surface 11 has an inner inclined surface 11a which is the most recessed in the cross-sectional view, a pull-in portion 11d in which the material is drawn according to the recess of the inner inclined surface 11a, and an outer shape which is recessed according to the drawn-in portion 11d. It has an outer inclined surface 11b.

The leg 1 has clearance regions 11c on both sides of the concave surface 11 which are three times or more the thickness of the material. By setting the clearance region 11c to a dimension that is three times or more the thickness of the material, even if the pressing surface Ka of the mold K presses the surface of the material on the short side in cross-sectional view, the material breaks or the like occurs. It's getting harder.

Then, in the present embodiment, in order to form the leg body 1 into a tapered shape in a side view, the inward inclination angle formed by the inner inclined surface 11a forming the concave surface 11 and the facing surface 12 is set to the outer inclined surface 11b and the facing surface 12. It is set to be approximately twice the outer inclination angle of the eggplant. In other words, as shown in FIG. 5, the amount of pushing by the pressing surface Ka of the mold K to form the inner inclined surface 11a is about twice the taper dimension of the outer inclined surface 11b forming a tapered shape. It is configured as follows.

Further, in this embodiment, as shown in FIGS. 9 and 10. The tip portion 16 has a cross-sectional shape formed into a substantially circular shape or an elliptical shape. Specifically, the tip portion 16 has a nut mounting portion 16a for embedding a nut member 17 having a female screw portion 17a, a separation region 16b for forming the nut mounting portion 16a, and a substantially circular cross-sectional shape. It has a curved processed surface 16c formed to form a shape, a first contact surface 16d that is in close contact with the nut member 17, and a second contact surface 16e.

Then, in the present embodiment, as shown in FIGS. 10 (a) and 10 (b), the tip portion 16 is formed with the concave surface 11 in a state where the separation region 16b is secured in advance (FIG. 10 (a)), and is separated. With the nut member 17 inserted in the region 16b, the material is plastically deformed by an appropriate pressing means X for plastically deforming the material (FIG. 10B). As a result, the tip portion 16 in which the nut member 17 is firmly fixed is suitably formed. Although not shown in the figure, arc welding may be performed separately at a portion where the first contact surface 16d and the second contact surface 16e that are in close contact with the nut member 17 are formed. In such a case, a welded joint will appear separately at the tip portion 16 in the figure.
