DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A spring hinge mounting method according to the present invention will be described below with reference to embodiments shown in the drawings. The spring hinge (not using the mounting method of the present invention) is shown in FIGS. 1 and 2 because it is first necessary to understand the spring hinge itself. One of the spring hinges is a leaf spring material (7) that is smoothly bent (FIG. 1 is an arc shape, and FIG. 2 is an example of a curved linear shape), and is a door (3). Has a base portion (7a) fixed to the back surface of the.

The summing support portion (7b) continuously extends from the base portion (7a) to enable the summing material (4) to be supported. As the leaf spring material (7), a metal leaf spring material such as a thin stainless plate (for example, about 0.15 mm) or a spring steel plate is used. However, a plate material (wall thickness is determined according to the material) of other material having sufficient spring characteristics other than metal is also applicable.

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).

Next, the other leaf spring material (17) has a linear protrusion and the wall thickness is the same as or similar to that of the leaf spring material (7) which is smoothly curved and protrudes. Is a metal such as a thinner stainless steel plate (for example, about 0.1 mm) and / or a narrower width, a spring steel plate, or a leaf spring material other than metal. The leaf spring materials (7) and (17) described above are used as one set each including one or more pieces to form a spring hinge for supporting the assembling material (4). That is, the upper surface of the leaf spring material (7) is fixed to the tip of the assembling support portion (7b).

A set of leaf spring material (7) including a combination material (4)
When fixed to (17), as shown in FIG. 3, leaf spring material (7)
Since the force of is stronger than the force of the leaf spring material (17), the bending causes the assembling material (4) to be inclined as a whole. The resulting angle of inclination of the dressing material (4) is such that the dressing material (4) is at an acute angle (less than 90 °) to the back of the door (3).
(Preferably 55 ° to 75 °).

As described above, the leaf spring materials (7) and (17) are fixed to the back surface of the door (3), and the assembling material (4) is inclined and overhanged to be 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 deflection of the leaf spring material (7) increases (because the initial shape is curved), and conversely the leaf spring material (17) bends (the initial shape is linear). Will be reduced.

Next, when the door (3) is opened, the leaf spring material (7) is used.
Due to the elastic force of the bending, the dressing material (4) returns to the initial state shown in FIG. In this way, upper and lower leaf spring materials (7)
The reason for making (17) different is that the guide surface (1
It corresponds to the fact that the force for pressing the assembling material (4) is applied only upward when (0) is provided only on one of the upper and lower sides (for example, only on the upper side). In this way, the dressing material (4) is brought into close contact with the back surface of the door (3) to the back surface of the door (2).

The above is a description of the spring hinge itself. Next, FIGS. 4 and 5 show a spring hinge in which the mounting method of the present invention is used. The spring hinge is fixed in the opposite direction of the assembling material (4). Stopper material (8) to stop the above retreat
To one or both (in the case of 3 or more, part or all)
It is installed. That is, the stopper material (8) is attached in a state of connecting the upper and lower ends of the back portion of the leaf spring materials (7) and (17) or their vicinity.

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

The body (8a) of the stopper material (8) is preferably thicker than the leaf spring materials (7) and (17) so that it can withstand the required compression force. The stopper material (8) is a leaf spring material (7) in which the countersunk screw (15) in the hole at the upper end of the stopper material (8) and the tail portion (8b) at the lower end of the stopper material (8) are locked in a state where the assembling material (4) inclines and projects. (1
By the engaging means constituted by the hole (7d) of the projecting piece of 7), the backward movement of the leaf spring material (7) (17) in the opposite direction to a certain degree or more is stopped and the forward movement is enabled.

Next, when the dressing material (4) is in close contact with the back surfaces of the doors (3) to (2), the stopper material (8) has its tail portion (8b) having a leaf spring material as shown in FIG. (7)
It is pulled out from the hole (7d) of the projecting piece of (17) and comes into a state of lying in close contact with the back of the leaf spring material (7) (17).
The countersunk screws (15) are used to allow the stopper material (8) to tilt with respect to the assembling material (4) as described above.

Therefore, instead of the flat head screw (15), a pan head screw or the like may be used as long as the stopper member (8) can be tilted by using a flat washer, a rubber ring, a spacer or the like corresponding to the flat plate. Tail part (8b) of stopper material (8)
The state of engagement between the hole (7d) of the projecting piece of the leaf spring material (7) (17) and the backward movement of the stopper material (8) is stopped at a certain position and the forward movement can be pulled out while sliding. It fits.

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. As the stopper material (8), either one having no elasticity or one having it (metal, plastic, etc.) can be selected, but when one having no elasticity is used, for example, a leaf spring material (7) (17) is used. The projecting piece may be lengthened to increase its flexibility and a hole (7d) may be provided near its tip to smooth the movement of the stopper member (8) while sliding.

Next, the base portion (7) of the leaf spring material (7) to be bent
As shown in FIG. 5, a) is attached to the door (3) with a screw (9) without allowing movement. On the other hand, a linear leaf spring material (1
The base portion (7a) of 7) is attached to the door (3) with only the center thereof being supported without using the screw (9) while being allowed to move.

That is, the base portion (7a) of the leaf spring material (17)
A hole (7c) is formed substantially in the center of the curved portion between the support and the support (7b).
Is provided. With the plate-shaped washer (13) interposed on the back side of the hole (7c), the plate screw (1
5) is inserted and the leaf spring material (17) is a dish-shaped washer (1).
3) and the head of the flat head screw (15).

However, the outer diameter of the hole (7c) is the flat head screw (15).
Is larger than the outer diameter of the screw (but smaller than the outer diameter of the head of the dish) and is loosely fitted with a gap. As described above, it is understood that the leaf spring material (17) is supported at the center thereof and the base portion thereof is allowed to move and is attached.

The leaf spring material (7) is also supported at its center by a countersunk screw (15), but this can be omitted. If there is a screw (9) on the base (7a), the countersunk screw (15) will be Not necessarily required.

In short, the leaf spring material (7) has its base (7).
It is attached to the door (3) without allowing movement in a). Thus, one of the reasons why the linear leaf spring material (17) is supported only at its center and the base portion (7a) is allowed to move and is attached is to save the screwing work time.

Since the leaf spring material (7) to the summing material (4) are continuous bodies, the leaf spring material (17) need only be supported at the center. Further, a linear leaf spring material (1
As for 7), when the door (3) is closed, the guide surface (1
0) is not provided on that side in many cases, so that it is necessary to prevent the assembling material (4) from being lifted up by the repulsive force of the spring. From this point as well, it is better not to fix the base portion (7a). Of.

Next, as another fixing method of the dressing material (4), FIG. 6 shows a method of fixing the leaf spring materials (7) and (17) along the back surface of the dressing material (4). The upper drawing of FIG. 6 shows that the assembly material (4) is fixed to the leaf spring material (7) so that the screw head (9) may be screwed into the hole with the projecting taper at the hole edge to prevent the screw head from protruding. Is.

The lower part of FIG. 6 shows that the tip is wrapped around the assembling material (4) to enable screwing from the surface, and the other construction is the leaf spring material (7) of FIG. )
The mounting configuration of is also applicable.
