DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention belongs to the technical field of packings installed between adjacent door plates and mounting standards of a biaxial hinge.

[0002]

2. Description of the Related Art Conventionally, as a packing structure of an folding door,
For example, those shown in FIGS. 9 and 10 are known.

The conventional folding door packing structure is disclosed in Japanese Patent Application No. 8-260253 and Japanese Patent Application No.
Biaxial hinge 1 proposed in No. 30296
Are used to connect adjacent door plates D.

The hinge 1 is composed of one substrate 11 and two blades 12 rotatably mounted on both ends of the substrate.
And a shaft 13 for aligning the substrate 11 and the blade plate 12. The hinge 1 is positioned such that the rear surface Da of the door plate D is flush with the rear surface Da with the rear surface Da of the door plate D as a mounting reference surface in the front-rear direction. The end face Db with the screw 2 by the screw hole 14
Attached and fixed. When closing the door plate D to which the hinge 1 is attached, a small gap Q
Is formed.

[0005] The packing 3 is selected to have a size corresponding to the remaining portion S of the end face Db of the door plate D to which the hinge 1 is attached, and is attached and fixed by an adhesive, a screw or the like.
When closing the door plate D to which the packing 3 is attached, the impact of the door plate D and the hinge 1 is absorbed and attenuated, and the gap Q is closed and concealed to improve the appearance.

[0006]

In the above-mentioned conventional folding door packing structure, the packing 3 of the door plate D is selected in order to select a packing 3 having a size corresponding to the remaining portion S of the end face Db of the door plate D to which the hinge 1 is attached. A large number of types of packings 3 having different dimensions corresponding to the thickness T and the front and rear width of the hinge 1 must be prepared, and there is a problem that packing manufacturing costs and inventory management costs increase.

When selecting the packing 3, the packing 3 should not be protruded from the front surface Dc of the door plate D in order to maintain the effect of ensuring the good appearance of the packing 3. Attention was needed. In particular,
Since the packing 3 closes the gap Q with the pair of packings 3, the length w from the base of the packing 3 to the trapezoidal ridge 32 is formed longer than half the width W of the gap Q. In this case, by closing the gap Q, the packing 3 is elastically deformed,
There was a concern that the packing 3 would protrude from the front face Dc of the door plate D to deteriorate its appearance.

This problem can occur even when the door plate D is provided with a hinge 1 having a structure other than the biaxial type.

The present invention has been made in consideration of such problems, and can improve the versatility of packing dimensions and can secure good appearance of the entire folding door. An object of the present invention is to provide a packing structure for an folding door.

[0010]

In order to solve the above-mentioned problems, a folding door packing structure according to the present invention employs the following means.

That is, in the first aspect, the door plate is rotatably connected by a hinge having a biaxial structure in which a small gap is formed between the adjacent door plates at the time of closing, and the gap is closed at the end face of the door plate. In the packing structure of the folding door to which the packing is attached, the packing is formed so as not to protrude from the front surface of the door plate even if the gap is closed from the front base portion of the trapezoidal shape having a hollow inside toward the ridge, and the packing is formed. A substantially L-shaped positioning portion which is positioned in contact with the end surface and the front surface of the door plate is provided, and the front surface of the door plate is attached with reference to the front-rear mounting direction, and the hinge is provided on the end surface of the door plate to which the packing is attached. It is characterized in that it is attached to the remaining part.

According to this means, the packing is mounted with the front surface of the door plate as a mounting reference in the front-rear direction by precisely contacting the L-shaped positioning portion with the end surface and the front surface of the door plate.
The hinge is mounted using the packing as a mounting reference in the front-rear direction. The difference in dimensions is eliminated by moving the hinge in the front-rear direction, and the elastic deformation is possible by the angle of inclination from the base of the trapezoidal shape toward the ridge. Is prevented from protruding.

According to a second aspect of the present invention, in the folding door packing structure of the first or second aspect, the packing is formed in a hollow trapezoidal shape, and a notch communicating with the inside is provided in a trapezoidal rear base portion. It is characterized by having been done.

According to this means, the large elastic deformation of the packing due to the cut contributes to the elimination of the dimensional difference, and the protrusion from the front surface of the door plate can be prevented.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of a folding door packing structure according to the present invention will be described below with reference to FIGS.

The hinge 1 of this embodiment is of a biaxial type, similarly to the above-described conventional example. However, in addition to the configuration of the above-described conventional example, a shaft 15 and a cam 16 are provided at the rotating front ends of the both blade plates 12, respectively.

Further, a block 4 is mounted on the front surface of the substrate 11 of the hinge 1 (on the rotating side of the blade plate 12) with screws 5.

An elastic body 7 is provided on the front surface of the block 4 at a position corresponding to the cam 16 provided on the blade plate 12 of the hinge 1. The elastic body 7 includes a slider 7 fitted to the slide 4 so as to be slidable in the front-rear direction of the block 4.
1, a coil spring 72 for urging the slider 71 so as to protrude forward, and a stopper 73 for preventing the slider 71 from coming off the block 9. The elastic body 7 is combined with the cam 16 of the blade plate 12 of the hinge 1 to form a catch structure for catching the blade plate 12 of the hinge 1 when the door plate D is closed. This catch structure
The hinge 1 is located at a position away from the shaft 13 which is the pivot of the blade plate 12 and exhibits a high catching force.

On the side surface of the block 4, an adjusting screw 6 for adjusting the amount of protrusion from the side surface of the block 4 by rotation is screwed. The adjusting screw 6 adjusts the contact angle of the blade plate 12 (door plate D) of the hinge 1 by adjusting the amount of protrusion, and corrects the meandering of the closed door plate D to make it even.

In the packing 3 of this embodiment, a substantially L-shaped positioning portion 31 is provided at the base portion in contact with the end surface Db and the front surface Dc of the door plate D, and a trapezoidal raised portion 32 is provided from the base portion.
Is raised. Since the positioning part 31 serves as a reference for mounting the packing 3 and also serves as a reference for mounting the hinge 1, it is preferable that the positioning part 31 is formed of a hard material in addition to plastic molding such as polyvinyl chloride resin. On the other hand, since the packing 3 needs to be deformed in response to the pressing of the raised portion 32, it is preferable that the packing 3 is formed of an elastic material such as an elastomer in addition to urethane rubber. The hollow portion 3 is provided inside the raised portion 32.
3 are provided. A notch 34 communicating with the hollow portion 33 is provided on the rear side of the base near the positioning portion 31.

According to this embodiment, the packing 3 is attached first.

The mounting of the packing 3 is performed by using the positioning portion 31 and using the front face Dc of the door plate D as a mounting reference in the front-rear direction.
It is brought into contact with the end face Db and the front face Dc of the door plate D and is fixed by an adhesive, a screw or the like.

Thereafter, the hinge 1 is mounted rearward with the rear end line L of the packing 3 on the end face Db of the door plate D as a mounting reference in the front-rear direction.

The rear mounted hinge 1 projects from the rear surface Da of the door plate D where the rear end (the substrate 11) of the hinge 1 is closed due to the relationship between the front and rear width of the hinge 1 and the thickness T of the door plate D. (See FIG. 3). However, the protruding portion a does not hinder the rotation of the wing plate 12 and the door plate D of the hinge 1 and is concealed by the packing 3 and does not impair the appearance.

The rear mounted hinge 1 is a hinge 1
, And the thickness T of the door plate D, the rear end of the hinge 1 may not reach the rear surface Da of the closed door plate D. In this case, the mounting state of the packing 3 does not cause any problem. (See FIG. 4). According to the attachment mode of the hinge 1 shown in FIG.
It is possible to prevent foreign matter from entering or being caught in the space.

The packing 3 attached first has a large elastic deformation on the side of the notch 34 due to the formation of the notch 34. Therefore, as shown in FIG. 5, the elastic deformation on the side of the cut 34 provides variability of a constant width c in the dimension in the front-back direction. Even if the raised portions 32 of both packings 3 press against each other, the packing 3 is elastically deformed on the side of the cut 34.
Does not protrude from the front face Dc of the door plate D, and good appearance is ensured. On the other hand, as shown in FIG. 6, even if the folding door opening / closing handle 8 is located between the two packings 3, the close contact of the packing 3 is ensured by the large elastic deformation on the cut 34 side.

As described above, the packing 3 is provided with versatility in terms of dimensions, and a large number of types of packings 3 having different dimensions corresponding to the thickness T of the door plate D and the front and rear width of the hinge 1 are prepared. No need to keep it.

FIGS. 7 and 8 show another embodiment of the packing.

As shown in FIG. 8, the packing 3 in the present embodiment has a trapezoidal shape in which the inclination angle X of the front surface 35 from the front base to the raised portion 32 is greater than the inclination angle X of the front surface 35 from the rear base to the raised portion 32. It is formed so as to be larger than the inclination angle Y of the surface portion 36. Specifically, when the material as described in the above embodiment is used, for example, the inclination angle X is about 8 to
Preferably, it is formed at about 20 degrees.

According to the present embodiment, even if the protrusions 32 of both packings 3 are pressed against each other by closing the gap Q, the front surface 35 can be largely elastically deformed by the inclination angle X. Thereby, without providing the cut 34, the packing 3 does not protrude from the front surface Dc of the door plate D, and good appearance is ensured. When the notch 34 is not provided in the packing 3, the trapezoidal shape of the packing 3 is stabilized, and the shape of the packing 3 can be prevented from changing when the door plate D is opened and closed.

As described above, in addition to the illustrated embodiment, it is also possible to combine with a hinge 1 other than the biaxial type.

[0032]

As described above, in the folding door packing structure according to the present invention, the packing is attached first, and the dimensional difference is eliminated by moving the hinge in the front-rear direction.
The versatility in the dimensions of the packing can be enhanced, and the manufacturing cost and the inventory management cost of the packing can be reduced.

Also, since an L-shaped positioning portion is provided in the packing or the inclination angle of the front side is increased to enable a large elastic deformation when the gap is closed, the front side of the packing is the front side of the door plate. There is an effect that the appearance can be kept good without protruding from the outside.
