SUMMARY OF THE INVENTION It is an object of the present invention to provide a spring hinge of a hinged door device for a double door and a hinged door device using the same, which can solve the above conventional problems and can significantly reduce the cost. .

[0004]

In order to achieve the above object, the present invention provides a leaf spring material having a summing support portion to which a summing material is continuously projected from a base portion fixed to the back surface of a door. The present invention proposes a spring hinge or the like in which one or more pieces form one set.

[0005]

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 the spring hinge of the invention in use, the spring hinge (7) having a base (7a) fixed to the back of the door (3).

The summing support portion (7b) continuously extends from the base portion (7a) 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 projecting inclination angle of the assembling support portion (7b) is such that the assembling material (4) forms an acute angle (smaller than 90 °) with the back surface of the door (3) (preferably 55 ° to 75 °).
°) to be fixed.

In the illustrated embodiment, the summing material (4) is fixed to the rear surface of the door (3) at the screw hole (7d) of the base portion (7a) and is fixed at the screw hole (7e) of the assembling support portion (7b).
Are fixed with screws (9). However, other fixing means such as an adhesive, a double-sided adhesive tape, or welding may be used instead of the screw (9). 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, in the spring hinge (7), the upper surface of the summing material (4) near the tip is fixed near 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.

As described above, the spring hinge (7) is fixed to the back surface of the door (3), and the assembling material (4) is inclined and supported by being extended. When the door (3) is closed in this state, as shown in FIG. 2, the assembling material (4) is, for example, the magnetic catch (11).
While coming into contact with the guide surface (10) such as the above and being guided, it enters the back surface of the other door (2).

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.

Next, when the door (3) is opened, the summing material (4) is returned to the initial state by the elastic force of the bending of the spring hinge (7). 3 and 4 show another spring hinge (7) of the present invention, which spring hinge (7) is a summing support (7).
It is characterized in that it has a stopper piece (7g) separated from b) and protruding from the base portion (7a).

It is desirable that the stopper piece (7g) has an inclination angle less than that of the assembling support portion (7b) in a natural state. The reason for this is that the return of the assembling support portion (7b) is pressed by the stopper piece (7g) so that the assembling material (4) does not shake in a natural state. Next, the opening (7c) is provided in the assembly support portion (7b) of the spring hinge (7) for adjusting the spring force, and the opening (7c) is unnecessary depending on the lateral width and the like. Also the door (3) of the spring hinge (7)
In Fig. 4, the base material (14) is pressed and fixed to strengthen the fixation.

FIG. 5 shows another spring hinge (7) of the present invention, wherein the spring hinge (7) is provided with a stopper material (13) for preventing the assembling material (4) from over-traveling in the opposite direction. ing. That is, the stopper material (13) has a base portion A fixed to the door (3) together with the base portion (7a) of the spring hinge (7).

A stopper portion B protruding forward and upward from the base portion A is continuous. The stopper portion B strengthens the function of the stopper piece (7g) shown in FIG. That is, the stopper portion B is located inside the opening (7c) of the spring hinge (7) to prevent the assembling material (4) from moving too far in the opposite direction. 6 and 7, the spring hinge (7) has a narrower width, and the stopper member (13) has a narrower width accordingly.

FIG. 8 is different from that shown in FIGS. 5 to 7 in that the stopper portion B of the stopper material (13) is made to abut not the assembling material (4) but the spring hinge (7) itself. Is being buffered. Ie spring hinges (7)
The stepped portion (7f) is provided at the stepped portion (7f), and the stopper portion B contacts the stepped portion (7f). Further, the base portion (7a) of the spring hinge (7) in FIG. 8 is embedded and integrated in the stopper material (13).

FIG. 9 shows another spring hinge (7) of the present invention, in which the summing support portion (7b) is smoothly curved and protrudes from the base portion (7a). This has the advantage that stress concentration does not occur in the spring hinge (7). FIG. 10 shows how the spring hinge is applied in the hinged door device of the present invention.

In other words, one set of two or more spring hinges (7) is used when two or more upper and lower spring hinges (7) and (17) support the assembling material (4) as shown in the figure.
Shows a combination support portion (7b) which is inclined upward, but the other spring hinge (17) has a narrow width.
Is protruding linearly. When the dressing material (4) is fixed, the dressing material (4) as a whole is tilted due to the inclination of the spring hinge (7) as shown in FIG.

Thus, the upper and lower spring hinges (7) (17)
The reason for changing the overhang state is that when the guide surface (10) shown in FIG. 2 is provided only on one of the upper and lower sides (for example, only on the upper side), the force for pressing the assembling material (4) is applied only on the upper side. It was done. 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).

Although the spring hinge (7) of FIG. 9 is used in FIGS. 10 and 11, the same applies when the spring hinge (7) of FIGS. 1 to 8 is used. Next, the lower spring hinge (17) in FIG. 12 is thinner than the upper spring hinge (7), and the summing support portion (7b) protrudes linearly. The lower spring hinge (17) in FIG. 13 is then less curved than the upper spring hinge (7).

The lower spring hinge (1 in FIGS. 10 to 13)
The width, wall thickness and bending (or inclination) of 7) are means for weakening the force than the upper spring hinge (7), and thus these may be used in combination.

FIG. 14 shows three or more spring hinges (7) (1).
When the assembling material (4) is supported by 7) and the guide surfaces (10) are provided at both upper and lower sides and the vertical dimension of the door (3) is long, the spring hinge (17) is provided at the intermediate portion of the assembling material (4). )
The object is to press it with and to bring it into close contact with the back surface of the door (3) or the door (2) also in the middle part. The spring hinge (17) is the same as the spring hinge (17) of FIGS. 10 to 13, and if the force (when using a plurality of springs, the total force) becomes weaker than the total force of the spring hinges (7) that are inclined and projected. Good.

10 to 14 show the ones using the spring hinges (7) and (17) including different leaf spring materials, but the hinged door device of the present invention uses the same leaf spring material. It goes without saying that this also includes the case where a plurality of 7) (if the overhang is a spring hinge (17) protruding linearly, it may be fixed at an angle) will be described later in FIGS. 23 and 24).

FIG. 15 shows a spring hinge (7) of the type shown in FIG.
The stopper material (13) of the type shown in FIG. The spring hinge (7) of FIGS. 16 and 17 is not an opening but a step portion (7f) is provided at the side edge, and the step portion (7f) abuts on the stopper portion B of the stopper material (13) to move in the opposite direction. It prevents overkill.

FIG. 18 shows a spring hinge (7) of the type shown in FIG.
The stopper material (13) of the type shown in FIG. 7 is used. FIG. 19 shows a spring hinge (7) of the type of FIG.
Similarly to the above, it is integrated with the stopper material (13).

FIG. 20 shows a spring hinge (7) of the type shown in FIG.
7 uses a stopper material (13) of the type shown in FIG. 7 (however, the stopper portion B is inclined so as to be along the assembling material (4)). FIG. 21 shows a spring hinge (7) of the type shown in FIG. 9 provided with a stopper piece (7g) as in the case of FIG. FIG. 22 shows the spring hinge (7) of the type shown in FIG.

The spring hinge (7) shown in FIG. 23 is a base material (14) made of a leaf spring material having a straight line extending from the assembly support portion (7b).
It is integrated with and tilted. The spring hinge (7) of FIG. 24 does not integrate the leaf spring material with the base material (14) and the groove (1
5) is engaged.
