DESCRIPTION OF THE PREFERRED EMBODIMENTS The spring hinge and hinged door device of the present invention will be described below with reference to the embodiments shown in the drawings. 1 and 2 show a spring hinge in use for the purpose of explaining the invention,
The spring hinge (7) is made of a leaf spring material having a base (7a) fixed to the back surface of the door (3).

The summing support portion (7b) continuously and smoothly extends from the base portion (7a) (for example, in an arc shape) to enable the summing material (4) to be supported. For the spring hinge (7), a metal leaf spring material such as a thin stainless steel plate (preferably 0.1 to 0.3 mm) or a spring steel plate is used. However, in addition to metal, a synthetic resin plate material having spring characteristics (the thickness is determined according to the material) is also applicable. The summing support part (7b) is smoothly continuous from the base part (7a) as described above, but the overhanging inclination angle of the end part of the summing support part (7b) is the door (3) in a free state in which the summing material (4) is stationary.
Acute angle (less than 90 °) to the back of
To 75 °).

In the illustrated embodiment, the assembling support portion (7) is fixed to the back surface of the door (3) through the screw hole of the base portion (7a).
The dressing material (4) is fixed with screws (9) in the screw holes of b). However, other fixing means such as an adhesive, a double-sided adhesive tape, or welding may be used instead of the screw (9). Further, the spring hinge (7) is omitted in FIG. 2 and the base material (14) is used in FIG. 1, but this shows that the base material (14) is auxiliary and can be omitted.

Next, in the spring hinge (7), the upper surface of the summing material (4) near the tip is fixed to the tip of the summing support portion (7b). The fixing of the summing support portion (7b) near the tip and the summing material (4) near the tip is advantageous for securing the length of the summing support portion (7b) as a cantilever. .

Therefore, depending on the material of the leaf spring material, the distance of the assembling material (4) from the back surface of the door (3), and the like, it is not necessary to fix them to each other near the tips. Two or more of the above leaf spring members are used as a set to form a spring hinge (7) for supporting the assembling member (4). That is, another spring hinge (17) forming one set may be the same as the spring hinge (7), but the width of the one shown in FIG. 1 is narrowed.
The reason for this is that the spring hinge (7) ensures an elastic force and the other spring hinges (17) play an auxiliary role with respect to the elastic force.

That is, the spring hinge (17) is an auxiliary in terms of elastic force, but plays an important function of supporting the assembling material (4) together with the spring hinge (7). As described above, the spring hinges (7) (1) are attached to the back surface of the door (3).
7) is fixed and the dressing material (4) is inclined and overhanged and supported. When the door (3) is closed in this state, as shown in FIG. 2, the dressing material (4) abuts against the guide surface (10) such as the magnet catch (11) and is guided while being guided to the back surface of the other door (2). Break into.

The guide surface (10) of the assembling material (4) is not limited to the magnetic catch (11), but a top plate, a bottom plate, a shelf plate, and other projecting members having a protruding shape, a concave cam, and a linear contact surface are exclusively used. A member or the like can be used. When the door (3) is closed, the assembly support (7) of the spring hinge (7) is
b) will bend.

When the door (3) is opened next, the assembling material (4) does not hit the other door (2) while following the guide surface (10) by the elastic force of the bending of the spring hinge (7). (It hits lightly even if it hits) It returns to the initial state. FIG. 3 shows another embodiment of the spring hinge (17) of FIG.

That is, as described above, the spring hinge (17) may be supplementary with respect to its elastic force, but the spring hinge (17) of FIG. 3 tries to reversely utilize the elastic force and positively utilize the opposite force. It is a thing. Since the upper and lower spring hinges (7) and (17) support the assembling material (4) when the door (3) is opened, the elastic force of the bending of the spring hinge (7) (this elastic force is larger). ) Spring hinge (1
7) is curved and eventually becomes the same state as shown in FIG. 1 and the dressing material (4) is inclined as a whole.

The reason why the elastic force of the spring hinge (17) is supplementarily (FIG. 1) or the opposite direction (FIG. 3) is that the guide surface (10) shown in FIG. This corresponds to the fact that the force for pressing the assembling material (4) is applied only upward when it is provided (for example only above).
As shown in FIG. 3, when the spring hinge (17) having a linear shape is used in the free state, when the assembling material (4) is pushed from the guide surface (10), the curvature of the spring hinge (7) is eliminated (returning). Accordingly, the spring hinge (17) becomes linear in a free state, so that the spring hinge (1)
The pressing force of 7) acts to press the assembling material (4) against the back surface of the door (3) or the door (2), so that the assembling material (4) as a whole covers the door (3) from top to bottom. ) Or door (2)
You will be able to adhere to the back of the.

Based on the above description of FIGS. 1 to 3, the spring hinge (7) of the present invention will be described with reference to FIGS. 4 to 6. That is, the spring hinge (7) (as well as the hinge (17)) has a stopper material (8) for stopping the backward movement of the assembling material (4) on one or both sides (in the case of three or more, part or It is attached to all). That is, the stopper member (8) is attached in a state where the upper and lower ends of the back portion of the spring hinge (7) are connected.

As a mounting method, a hole is provided at the upper end of the stopper member (8), and the stopper member (8) is mounted so that it can be tilted with respect to the assembling member (4) by a countersunk screw (15). Next, the lower end of the stopper material (8) is
A narrow tail portion (8b) is projected from a) and the tail portion (8b) is inserted into the hole (7d) at the end of the base portion (7a) of the spring hinges (7) (17).

The body (8a) of the stopper material (8) is made thicker than the wall thickness of the spring hinge (7) so that it can withstand the necessary compressive force. When the dressing material (4) is inclined and overhangs, the stopper material (8) has a flat head screw (15) in the hole at the upper end and a tail portion (8) at the lower end.
b) is stopped by the engaging means constituted by the hole (7d) of the spring hinge (7) with which the spring hinge (7) is stopped and the backward movement of the spring hinge (7) is stopped so that the forward movement is possible. Will be installed.

Next, when the dressing material (4) is in close contact with the back surface of the door (3) or the door (2), the stopper material (8) has its tail portion (8b) whose spring hinge (8b) as shown in FIG. The spring hinge (7) is pulled out from the hole (7d) of 7) and comes into a state of lying close to the back of the spring hinge (7). Flat head screw (1
The reason (5) is used is to allow the stopper member (8) to tilt with respect to the assembling member (4) as described above.

Therefore, a pan head screw or the like may be used instead of the countersunk screw (15) as long as the stopper member (8) can be tilted by using a dish washer, a rubber ring, a spacer or the like corresponding to the dish. Tail part (8b) of stopper material (8)
The engagement state of the hole (7d) of the spring hinge (7) is such that the backward movement of the stopper material (8) is stopped at a fixed position and the forward movement is slidably pulled out.

Therefore, not only the combination of the tail portion (8b) and the hole (7d) but also various engaging means such as engaging a hook-shaped member with the groove of the mating member may be used. The stopper material (8) may be either inelastic or inelastic (metal, plastic, etc.), but the spring hinge (7) itself is flexible even if an inelastic material is used. Therefore, it is possible to move the stopper member (8) while sliding it.

Next, the support of the base portion (7a) of the spring hinge (7) near the summing support portion (7b) by the countersunk screw (15) will be described. That is, as shown in FIG. 6, the cylindrical body (1) is attached to the lower surface of the hole (7c) of the spring hinge (7).
3) is interposed.

The upper end surface of the cylindrical body (13) is inclined in the outer peripheral direction, because the curvature of the spring hinge (7) is absorbed by this inclination and the inclination of the countersunk screw (15). The spring hinge (7) is attached to the door (3) by using the tubular body (13).
The reason for maintaining a state of being slightly lifted from the back surface of the dressing material (4) is that the lower end corner of the dressing material (4) is in the middle of the movement of the dressing material (4) being in close contact with the back surface of the door (3) or the door (2). Door (3)
This is because the back surface of the is lifted so that it does not slide (sliding with a light force even if it slides).

Further, the hole (7c) is made slightly larger than the outer diameter of the screw portion of the countersunk screw (15) so as to be able to absorb the displacement of the position of the hole (7c) due to the movement of the spring hinge (7). Next, instead of the cylindrical body (13), an inclined support body (18) which is long in the left and right direction and inclined forward and backward as shown in FIG. 7 may be used.

Further, as shown in FIG. 8, when the force for pressing the assembling material (4) on the inclined support body (18) is applied to only one side, the opposite end to this force is fixed with a flat head screw (15). You may In the above description, the cylindrical body (13) and the inclined support (1
8) was fixed with a countersunk screw (15), but if it is possible to absorb the tilting motion caused by the movement of the spring hinge (7) by using a plate-shaped washer, a rubber ring, a spacer or the like corresponding to the plate, the countersunk screw (15 ), A pan head screw or the like may be used.
