Abstract

PURPOSE:To make it possible to support a frame body in stable state by inclining a leg section outwards of the frame body with respect to the vertical line to the longitudinal direction of the base section. CONSTITUTION:An engagement pawl 16 is inserted into the engagement hole of a metal fixture 9 for fixing in order to be engaged in the hole and a bolt 41 goes through the fixture 9 for fixing and screwed into a screw hole 17 to fix base section 11. When in this state a leg section 24 is expanded outwards of a frame body 2, the upper section of an engagement piece 29 descends gradually as it abuts a stopper 18 and when it passes the lower end of said stopper, the engagement piece 29 is pushed up by a spring 28 into the state of engagement. Further, if the leg section 24 is expanded outwards, a hinge cover 31 on the side of the leg section 24 abuts the lower face of a hinge cover 22 on the side of the base section 11 and stands up vertically, and the leg section 24 inclines outwards by an angle of theta. After this, a load given to the frame body 2 is transmitted to the leg section 24 through the base section 11 with the main body 1 of a foot warmer used in this arrangement, and the foot warmer can be used in stable state.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a wooden leg device that is most suitable for a so-called furniture-like kotatsu using natural wood.

(b) Conventional technology This kind of furniture-like kotatsu has become the mainstream of kotatsu, and its legs are made of solid, heavy natural wood to give it a luxurious and solid feel.

However, as mentioned above, since the use of natural wood increases the overall weight including the frame and legs, for example, as shown in Japanese Utility Model Application Publication No. 59-98109, the thickness of the crosspieces may be increased or the legs may be made thicker. The body was made thicker to make it stronger, but as a result it was several times heavier than a regular kotatsu with plastic legs, making it difficult to handle. In particular, it was necessary to further increase the strength of those with bendable legs.

(c) Problems to be Solved by the Invention The object of the present invention is to hold the frame in a stable state in a structure in which the legs are bendable.

(d) Means for Solving the Problems The present invention provides a frame body formed by combining a plurality of crosspieces;
A plurality of wooden legs supporting the frame are provided at appropriate positions on the frame, and the legs are composed of a base fixed to the crosspiece and a leg pivoted to the base so as to be bendable. , the leg portion is configured to be inclined toward the outside of the frame with respect to a vertical line in the longitudinal direction of the base portion.

(E) Function The present invention is composed of a base for fixing the legs supporting the frame to the crosspiece, and legs pivoted to the base so as to be bendable, and the legs are aligned with the vertical line in the longitudinal direction of the base. On the other hand, since the frame is provided so as to be inclined outwardly, all the legs are slightly expanded outward, and the main body can be stably supported.

(f) Example Embodiments of the present invention will be described based on the drawings.

(24) (24) (24) (24) is the base (
II) (Ili (Ill) (Ill) A wooden leg pivoted so that it can be bent freely, and when bent and raised, as shown in Figure 4, the frame ( 2) is inclined outward by an angle (θ).This angle (θ) is such that the upper end surface of the leg (24) is inclined toward the inside of the frame (2) as shown in Fig. 4. A taper (25) is provided which is cut or machined so as to become lower in the direction, and this angle (A+) is the same angle as the above-mentioned angle (θ).

The leg portion (24) has a screw hole (26) on its upper end surface.
) (26) (26+, pivot piece (27) +27)
a hinge cover (31) that covers the periphery of the lower hinge body with a lower hinge body (30) interposed therebetween and having an engager (29) inside thereof that is constantly urged upward by a spring (28);
And the bottom plate (32) is connected to the screws (33) (by means of 331, the respective screw through holes (34) (34), (35) (35+,
(36N36) and fix by screwing. As shown in FIGS. 2 and 4, the hinge cover (31) is integrally provided with a protrusion (37) at the upper part of its front surface (the surface facing inside the frame).

(38) is the pivot piece +19) +191, In)
The shaft pin (39) is a ring 1 for preventing the shaft pin from being removed, and (40) is a cord connected to the heater unit (7).

In this way, the locking claw (16) is inserted into the locking hole (not shown) of the fixing metal fitting (9) to lock it, and the bolt (41) is inserted into the fixing metal fitting (9).
9) and screws into the screw hole (17) to fix the base (11). In this state, when the legs (24) are expanded outward of the frame (2), the upper part of the engager (29) gradually descends while hitting the stopper (18), and when it passes the lower end of the stopper, it engages. The goggle (29) is pushed up by the spring (28) and becomes locked. Furthermore, the legs (2
4) slightly outward, the hinge cover (31) on the leg (24) side is aligned with the hinge cover (2) on the base (11) side.
2) and becomes an upright state, and the legs (24) are inclined outward by an angle (θ).

Thereafter, the kotatsu main body (1) is used in this state, but the load applied to the frame (2) is transmitted to the legs (24) via the base (11), making it possible to use it in a stable state. can.

Therefore, for reasons such as storing the kotatsu body (1), the legs (
24), press the long button (15) to release the engagement between the engager (29) and the swimmer (18), and then move the leg (24) toward the inside of the frame (2). When bent, the protrusion (37) hits the lower surface of the locking claw (16) and is locked to the step (43) of the sliding claw (16), thereby maintaining the bent state of the leg (24).

In addition, in the present invention, a taper is formed on the upper end surface of the leg in order to incline the leg toward the outside of the frame, but a taper may be formed on the lower end surface of the base, and either one of the hinge covers The same is true even if a taper is provided.

(l.) Effects of the Invention As described above, in the present invention, the legs are inclined outward from the frame with respect to the vertical line in the longitudinal direction of the base, so that the load applied to the frame is applied to the legs further outward. The frame can be supported in a stable state by acting so as to expand. In addition, since it uses a wooden base and wooden legs, and the legs are slanted as mentioned above, it can give a sense of luxury and solidity, and the base is perpendicular to the legs. Since it is fixed to the crosspiece, there is no need to create and process the crosspiece, making it easy to fix the base and the crosspiece.

Since the inclination of the leg is formed by providing a taper on one of the overlapping surfaces of the base and the leg, there is no need to perform any special processing on the bending mechanism or the like. Furthermore, as the legs are bent, the protruding part of the hinge cover that covers the lower hinge body on the leg side engages with the locking claw on the upper hinge body on the base side, causing the legs to inadvertently move in the standing direction. There's nothing to do.
