The present application is a national stage filing under 35 U.S.C ยง 371 of PCT application number PCT/JP2018/022583 filed on Jun. 13, 2018 which is based upon and claims the benefit of priority to Japanese Patent Application No. 2017-130731, filed on Jul. 3, 2017.
The present invention relates to a hinge to connect one pivoting body to another pivoting body in a relatively pivotable manner and to a hinge roll.
Conventionally, a hinge has been used to pivotably connect an opening frame (door frame) and a shield (door), for example.
The hinge typically includes a pair of flat vanes and a pivot shaft that pivotably connects these vanes (for example, refer to Patent Literature 1). One vane is attached to the opening frame and the other vane is attached to the shield, so that the opening frame and the shield are pivotably connected around the pivot shaft.
Patent Document
Patent Literature 1: JP 2016-35172 A
However, with this hinge, when a failure occurs in coupling the opening frame and the shield, pivoting motion of the opening frame or the shield is not made smoothly, or noise occurs during the pivoting thereof.
Considering the foregoing, an object of the present invention is to provide a hinge that allows pivoting bodies to smoothly pivot relative to each other, and a hinge roll.
A hinge according to the present application is a hinge to connect one pivoting body to another pivoting body in a relatively pivotable manner, the hinge including a sheet body that is configured by layering sheet members, one end of the sheet body being attachable to the one pivoting body and another end of the sheet body being attachable to the other pivoting body, the sheet body including a pivot shaft that is disposed between the layered sheet members so as to allow the one end and the other end of the sheet body to pivot relative to each other.
One aspect of the present application allows pivoting bodies to smoothly pivot relative to each other.
The following describes a hinge according to a first embodiment of the present invention with reference to the drawings.
The hinge 1 includes a sheet body 2 that has a rectangular sheet-like shape.
The sheet body 2 has one end 2a on one end in a width direction W thereof that is attachable to a door frame (one pivoting body), and another end 2b on the other end thereof that is attachable to a door (another pivoting body).
The sheet body 2 is configured with a first sheet member 21 and a second sheet member 22 that are flexible and are formed of fibers such as carbon fibers, being layered in a thickness direction.
The first sheet member 21 and the second sheet member 22 each include fibers woven with inclination from one end to the other end of a height direction H with respect to a pivot shaft 3, which will be described later. Specifically, at least part of the fibers in the first sheet member 21 and the second sheet member 22 is arranged with inclination at 45 degrees with respect to the pivot shaft 3.
The first sheet member 21 and the second sheet member 22 are bonded to one another on the one end 2a and the other end 2b with an unillustrated adhesive agent, resin, or the like.
The sheet body 2 is provided with the pivot shaft 3 in a center part thereof in the width direction W.
The pivot shaft 3 includes a bulge 3a and an axial member 3b.
The bulge 3a is integrally configured with the second sheet member 22 with the center part thereof in the width direction W bulging outward in a curved manner on one major face 22a side of the second sheet member 22. The bulge 3a has an inner space 3c that is decentered toward the one major face 22a side. Specifically, as illustrated in
The inner space 3c of the bulge 3a houses the axial member 3b that extends in an elongated manner. The axial member 3b is formed of a nylon wire and the like, for example, and is extended over the overall length in the height direction H of the sheet body 2. The axial member 3b is provided in a decentered space 3e between the highest bulge point 3d and a virtual line 22L on the one major face 22a, in the inner space 3c. Specifically, the axial member 3b is provided in the inner space 3c so as to be decentered toward the one major face 22a side.
It should be noted that the pivot shaft 3 allows the one end 2a and the other end 2b to pivot relative to each other, with the axial member 3b serving as a pivot center B during the relative pivoting. Specifically, since the axial member 3b is provided in the inner space 3c so as to be decentered toward the one major face 22a side, the pivot center B is set so as to be decentered toward the one major face 22a side.
The relative pivoting refers to the pivoting of the one end 2a and the other end 2b relative to each other, and includes the pivoting of the other end 2b alone with the one end 2a fixed, the pivoting of the one end 2a alone with the other end 2b fixed, and the pivoting of both the one end 2a and the other end 2b, for example.
As illustrated in
The hinge 1 is manufactured with the following process, for example.
In
First, the first sheet member 21 and the second sheet member 22 are stacked one on another in the thickness direction thereof with the axial member 3b interposed therebetween. Then, with a portion having the axial member 3b disposed therein in the second sheet member 22 and the recess E1 facing vertically opposite to each other, the pressing die E descends to the second sheet member 22 from above, and at a certain time, the pressing face contacts the second sheet member 22. The pressing face further presses the second sheet member 22 downward.
In this process, with the one end 2a and the other end 2b being pressed with the pressing face, the portion opposite to the recess E1 in the second sheet member 22 is pressed to the inner face of the recess E1 while being retained inside the recess E1 together with the axial member 3b, so that the bulge 3a is formed that bulges according to the shape of the recess E1. Consequently, the inner space 3c is formed inside the bulge 3a, so that the axial member 3b is disposed in the inner space 3c.
As illustrated in
The hinge roll 10 is cut in a direction crossing the longitudinal direction to produce the hinge 1 in
Next, operations or the like of the hinge 1 will be described with reference to
Symbol D1 denotes a door frame and D2 denotes a door.
As illustrated in
In this case, at least part of the fibers of the first sheet member 21 and the second sheet member 22 is arranged with inclination downward from the one end 2a to the other end 2b. Specifically, the at least part of the fibers of the first sheet member 21 and the second sheet member 22 is arranged with inclination downward from the door frame D1 to the door D2.
It should be noted that in
In this case, the sheet body 2 is in a folded state by pivoting relative to the first sheet member 21 side with the axial member 3b serving as the pivot center B. Then, a plane D11 of the door frame D1 and a plane D21 of the door D2 are arranged flush with one another, and the pivot shaft 3 is arranged in a position in which the pivot shaft 3 projects outward from the planes D11 and D21.
In the above-described state, a user is opening the door D2 with respect to the door frame D1. Then, as illustrated in
Then, as illustrated in
In this case, the door D2 is arranged in an open position F2 in which the door D2 is opened at 180 degrees with respect to a close position F1 with the axial member 3b serving as the pivot center B. Furthermore, the other end 2b is opened at 180 degrees with respect to the one end 2a so as to be flush therewith.
In contrast, with the door D2 arranged in the open position F2, when the door D2 is being closed, with an operation opposite to the above-described operation, the door D2 is arranged in the close position F1.
From the foregoing, with the hinge 1 according to the first embodiment, the one end 2a and the other end 2b of the sheet body 2, which is configured by layering sheet members, pivot relative to each other with the pivot shaft 3 serving as the pivot center B, which allows the door frame D1 and the door D2 to smoothly pivot relative to each other.
Furthermore, the sheet body 2 is formed of the sheet members, which makes it possible to attach the sheet body 2 to the door frame D1 and the door D2 without forming any recess for attachment in the door frame D1 and the door D2, so as to reduce an installation distance between the door frame D1 and the door D2. For example, when the sheet body 2 is formed of thin sheet members, it is possible to reduce the installation distance between the door frame D1 and the door D2.
The sheet body 2 is formed of flexible sheet members formed of fibers, which makes it possible to flexibly deform and attach the sheet body 2 on a fitting surface that is not a flat surface.
Providing the axial member 3b not only allows the door frame D1 and the door D2 to easily pivot with the axial member 3b serving as the pivot center B, but also increases the durability of the pivot shaft 3.
Providing the bulge 3a allows the one end 2a and the other end 2b to easily pivot relative to each other toward the first sheet member 21 side.
The pivot center B, which allows the one end 2a and the other end 2b to pivot relative to each other, is set so as to be decentered toward the one major face 22a side.
This decentering makes it possible to shift the pivot center B outward from the plane of each of the first sheet member 21 and the second sheet member 22. Thus, simply disposing the pivot center B outside the plane D11 and the D21 of the door frame D1 and the door D2 makes it possible to open and close the door D2 at 180 degrees with the hinge 1 prevented as much as possible from being exposed from the door frame D1 and the door D2.
Furthermore, disposing the axial member 3b between the highest bulge point 3d and the virtual line 22L on the one major face 22a makes it possible to easily open and close the door D2 at 180 degrees with the hinge 1 prevented as much as possible from being exposed from the door frame D1 and the door D2.
The first sheet member 21 and the second sheet member 22 include the fibers woven with inclination with respect to the pivot shaft 3. Thus, disposing the fibers with inclination downward from the door frame D1 to the door D2 allows the fibers to have durability in the longitudinal direction thereof against the pulling force due to the weight of the door D2, which makes it possible to easily open and close the door D2 without any descent of the door D2.
Providing the identification part 4 makes the position of the pivot shaft 3 easily visually recognized from the outside, and thus allows the hinge 1 to be easily mounted.
The hinge roll 10 is configured with a plurality of hinges 1 integrally rolled in a roll shape. This configuration makes it possible to bring the hinge roll 10 to a site where attachment of the hinge 1 is to be performed and easily attach the hinge 1 by cutting the hinge roll out at this site depending on the heights of the door frame D1 and the door D2 at the time of attachment of the hinge 1.
Specifically, the sheet body 2 has a very small thickness, which eliminates the necessity of shaving the door frame D1 and the door D2 at the site where the hinge 1 is to be attached, thereby reducing work time and unit price of the work.
Next, a second embodiment of the present invention will be described.
In
The second embodiment has the same basic configuration as the basic configuration in the first embodiment, and different points are mainly explained.
A hinge 1a in the second embodiment includes a soft resin part 3f that is formed of soft resin. The soft resin part 3f is extended over the overall length in the height direction H in the inner space 3c.
This soft resin part 3f is provided when soft resin is filled in the inner space 3c with the axial member 3b disposed therein.
The soft resin part 3f is provided between the highest bulge point 3d and the virtual line 22L on the one major face 22a. Specifically, the soft resin part 3f is provided in the inner space 3c so as to be decentered toward the one major face 22a side.
The soft resin part 3f is disposed along the inner face of the bulge 3a and so as to be flush with the one major face 22a, and has a cross section that is formed in a semicircle shape.
From the foregoing, with the hinge 1a in the second embodiment, providing the soft resin part 3f allows the one end 2a and the other end 2b to easily pivot relative to each other with the pivot center B serving as a center.
Furthermore, providing the axial member 3b and the soft resin part 3f allows the one end 2a and the other end 2b to further easily pivot relative to each other with the pivot center B serving as a center.
Furthermore, disposing the soft resin part 3f between the highest bulge point 3d and the one major face 22a makes it possible to easily open and close the door D2 at 180 degrees with the hinge 1a prevented as much as possible from being exposed from the door frame D1 and the door D2.

In
The third embodiment has the same basic configuration as the basic configuration in the first embodiment, and different points are mainly explained.
A hinge 1b in the third embodiment includes a reinforcing sheet (reinforcing plate) 5 disposed between the first sheet member 21 and the second sheet member 22.
The reinforcing sheet 5 is formed of metal, resin, or fiber, for example, and formed in a rectangular plate shape. Furthermore, the reinforcing sheet 5 is bonded to each of the one end 2a and the other end 2b with an adhesive agent.
It should be noted that in the third embodiment, the axial member 3b is not provided, but the soft resin part 3f alone is provided to the inner space 3c. In this case, the pivot center B is set inside the soft resin part 3f.
From the foregoing, with the hinge 1b in the third embodiment, providing the reinforcing sheet 5 allows the one end 2a and the other end 2b to be reinforced, thereby making it possible to increase allowable load with respect to the weight of a pivoting body to be attached.
It should be noted that while the reinforcing sheet 5 is provided to each of the one end 2a and the other end 2b, embodiments are not limited thereto and are changeable as appropriate. For example, the reinforcing sheet 5 made of metal, resin, or the like may be provided to each of the one end 2a and the other end 2b. The reinforcing sheet 5 made of fibers or the like may be integrally provided to both the one end 2a and the other end 2b, instead of being separately provided thereto.
Next, a fourth embodiment of the present invention will be described.
In
The fourth embodiment has the same basic configuration as the basic configuration in the first embodiment, and different points are mainly explained.
A hinge 1c in the fourth embodiment includes a third sheet member 23 disposed between the first sheet member 21 and the second sheet member 22. The first sheet member 21, the second sheet member 22, and the third sheet member 23 are integrally connected to one another. Specifically, the first sheet member 21, the second sheet member 22, and the third sheet member 23 are constituted of one sheet member that is folded. More specifically, one end of each of the first sheet member 21 and the third sheet member 23 includes a connecting part 20a serving as a folding portion. The other end of each of the second sheet member 22 and the third sheet member 23 includes a connecting part 20b.
