It is assumed to straddle the recess in both the width direction and the width direction.

  According to a fifth aspect of the present invention, there is provided an opening / closing device configured to attach / detach the buffer member to / from the opening / closing body, the storage device including a storage portion for storing the opening / closing body on an opening direction side thereof. A storage port for storing the opening and closing member is formed so as to be able to store the opening and closing body when the opening operation is performed and the buffer member attached to the opening and closing body.

The storage section in the fifth aspect of the invention may be an aspect in which the opening / closing body is wound up and stored on the opening direction side, or an aspect in which the opening / closing body is stored in the opening direction side without being wound up. It may be.
As a specific example of the storage opening, the opening / closing body is formed to have a width dimension (dimension in the opening / closing body thickness direction) larger than the dimension in the opening / closing body thickness direction in a state where the buffer member is mounted on the opening / closing body. The

In the present specification, the “opening / closing body thickness direction” means the thickness direction of the opening / closing body in the closed state.
In the present specification, the “opening / closing body width direction” means a direction that is substantially orthogonal to the opening / closing direction of the opening / closing body and not the thickness direction of the opening / closing body.
Further, in this specification, the “opening / closing body opening / closing direction” means a direction in which the opening / closing body slides to partition or open the space.

Since the present invention is configured as described above, the following effects can be obtained.
According to the first invention, when the opening / closing body is bent in the thickness direction by a strong wind or the like when mounted on the opening / closing body, between the bent opening / closing body and an object such as a screen door, for example. The opening / closing body can be prevented from coming into direct contact with the object by interposing the elastic portion. As a result, it is possible to suppress the occurrence of vibrations and noise, and damage to the opening / closing body and the object due to the opening / closing body drowning in a strong wind.
Moreover, when not in use, the appearance of the opening / closing body can be improved by removing the buffer member.
In addition, even if the buffer member is forgotten to be removed when not in use, the buffer member may come off due to contact with the lintel portion or the like when the opening / closing body is opened. Therefore, it is possible to reduce problems such as the opening operation of the opening / closing body being hindered by the buffer member or the lintel portion being damaged.

  Furthermore, according to the second invention, since the elastic portion is elongated, the elastic portion can be easily arranged to correspond to a specific object such as a vertical screen of a screen door. Even if it is in the middle opening / closing position and the screen of the screen door is not located near the center of the opening / closing body width direction, if the elastic portion is arranged so as to cross the screen of the screen door, the elastic portion Can be easily brought into contact with the screen door.

Furthermore, according to the fourth aspect of the present invention, the buffer member can be easily attached to the opening / closing body without being restricted by the size of the recess of the slat.
In other words, if the detachable portion is configured to fit into the recess of the slat, when mounting the elastic member to the recess, a mounting failure may occur due to variations in the width of the recess of the slat. Moreover, since the width dimension of the recessed part of a slat changes with opening-and-closing bodies, it is necessary to prepare the said buffer member according to the recessed part dimension.
According to the present invention, mounting failure does not occur as described above, and mounting is easy even with opening / closing bodies having different width dimensions of the recesses.
Moreover, it can be easily mounted on either the front or back of the opening / closing body, and can be easily mounted anywhere on the front or back of the opening / closing body, and the mounting position is limited. Few.

Furthermore, according to the fifth aspect, when the opening / closing body with the buffer member mounted is opened and stored in the storage unit, the buffer member is passed through the storage port of the storage unit to open and close It can be stored in the storage unit together with the body.
Therefore, it is possible to improve the storage performance of the buffer member, and to reduce problems such as the opening operation of the opening / closing body being hindered or the storage opening being damaged by the buffer member when it is forgotten to be removed. Can do.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

It can be attached to an opening / closing device that partitions or opens the space inside the construction / structure. In the present embodiment, an example will be described in which the buffer member according to the present invention is detachably attached to a window shutter device disposed on the outdoor side of the window portion.

The opening / closing device 1 that is a window shutter device includes an opening / closing body 10 that slides up and down to open and close, left and right guide rails 20 and 20 that guide both ends of the opening / closing body 10 in the opening / closing direction, and an opening / closing operation. A storage portion 30 (see FIG. 4) for storing the opening / closing body 10 on the opening direction side of the body 10 is fixed to the outdoor side (upper side according to FIG. 1) of the window sash A installed in the opening of the structure. (See FIG. 1).
A buffer member 40 is detachably mounted on the indoor side (lower side according to FIG. 1) of the opening / closing body 10 in the opening / closing device 1.

The opening / closing body 10 constitutes the opening / closing body main body 11 by connecting a plurality of slats 11a formed by bending a horizontally long substantially rectangular metal plate into a substantially concave shape so as to rotate between adjacent slats in the vertical direction. A seat plate member 12 (see FIGS. 2 and 3) for contacting an unillustrated lower frame member is connected to the lower end of the opening / closing body 11 in the opening / closing body width direction.
The material of each slat 11a is, for example, a magnetic body such as a steel plate so that a buffer member 40 described later can be magnetically attracted.

  The guide rail 20 is formed in a substantially U-shaped cross section so as to surround the widthwise end of the opening / closing body 10, and is disposed between the lower frame member and the storage portion 30.

The storage unit 30 includes a winding shaft 32 that winds and unwinds the opening / closing body 10 in a storage case 31 (see FIG. 4).
The storage unit 30 has a configuration in which the winding shaft 32 is electrically rotated in both directions, a configuration in which the winding shaft 32 is electrically rotated only in one direction, and is manually rotated in the opposite direction, Any mode such as a mode in which the winding shaft 32 is manually rotated in both directions may be used.

The storage case 31 is formed in a long box shape extending in the width direction of the opening / closing body, and has a storage port 31a for storing and feeding the opening / closing body 10 at the lower end thereof.
The storage port 31 a is a through hole having a substantially rectangular shape in a plan view over substantially the entire length in the width direction of the opening / closing body 10. When the opening / closing body thickness direction is attached to the opening / closing body 10, The buffer member 40 is appropriately set so as to pass therethrough.

  The buffer member 40 includes an attachment / detachment portion 41 that can be attached to and detached from the front portion or the back portion of the opening / closing body 10, and an elastic portion 42 that is formed so as to protrude from the front portion or the back portion in the opening / closing body thickness direction. It is constructed integrally.

The detachable portion 41 is a member formed in a substantially long band shape by a so-called rubber magnet obtained by mixing a pulverized magnet with rubber.
According to the illustrated example, the attaching / detaching portion 41 has a width dimension (a dimension in the left-right direction in FIG. 5) set slightly larger than the recess 11 a 1 (see FIG. 3) of the slat 11 a of the opening / closing body 10.
The length of the detachable portion 41 is set to be longer than the concave portion 11a1 of the slat 11a of the opening / closing body 10 and extend along the front or back of the opening / closing body 10. Yes.
Further, as another example of the attaching / detaching portion 41, a rubber plate or a synthetic resin plate may be laminated and bonded to the rubber magnet.

The elastic portion 42 is made of rubber or elastic synthetic resin material. According to an example shown in FIG. 5, the contact portion 42a for contacting the object in the thickness direction of the opening / closing body 10 and the corresponding contact portion 42a. And a base 42c that supports the support neck and is bonded to the detachable portion 41.
According to the illustrated example, the contact portion 42a has a hollow portion 42a1 extending in the length direction so that appropriate elasticity can be obtained, and the protruding end portion (lower end portion in FIG. 5) has a substantially curved convex shape. Is formed.
The support neck portion 42b is formed to have a width smaller than that of the contact portion 42a, thereby securing the groove portions 42b1 and 42b1 on both sides in the width direction between the contact portion 42a and the base portion 42c.

Therefore, according to the elastic part 42 having the above-described configuration, the impact when the contact part 42a contacts the object (specifically, the vertical frame a1) can be absorbed by the hollow part 42a1 and the groove parts 42b1 and 42b1. Is possible.
In addition, as another simple structural example, it is good also as a structure which excluded either one of the hollow part 42a1 and groove part 42b1, 42b1. Further, both the hollow portion 42a1 and the groove portions 42b1 and 42b1 can be omitted, and the impact can be absorbed only by the material elasticity of the elastic portion 42.

The window sash A, which is the installation target of the opening / closing device 1, includes a screen door a so as to face the outdoors, and has a glass door (not shown) on the indoor side of the screen door a.
The screen door a is provided on one half side in the width direction in the opening of the window sash A (the left half side according to FIG. 1), and the vertical door a1 constituting the screen door a It is located at the approximate center in the width direction at the opening of the sash A. The screen door a can slide in the width direction.

Next, the operation and effect when the buffer member 40 is attached to the opening / closing device 1 will be described.
The buffer member 40 having the above configuration is attached to the indoor side surface of the opening / closing body 10 in the opening / closing direction as shown in FIG. 2, for example.
At the time of this mounting, the buffer member 40 is positioned in the opening / closing body width direction corresponding to one vertical frame a1 of the screen door a in the window sash A, and is attached to the opening / closing body 10 which is a magnetic body by the magnetic force of the attaching / detaching portion 41. Adsorbed.
According to this mounting mode, when the opening / closing body 10 bends indoors due to strong winds or the like, the elastic portion 42 of the buffer member 40 contacts the one vertical frame a1 of the screen door a. Direct contact with the vertical frame a1 can be prevented.
In addition, since the buffer member 40 is disposed in the opening / closing body opening / closing direction, the opening / closing body 10 is bent in the opening / closing body opening / closing direction, and the frictional noise generated at the connecting portion between the slats 11a, 11a adjacent to each other vertically. Etc. can be relaxed.

It should be noted that the buffer member 40 that is attracted by the magnetic force can be easily removed during normal times when no strong wind or the like is generated. Therefore, it is possible to prevent the buffer member 40 from impairing the appearance of the opening / closing body 10 or hindering the opening / closing operation of the opening / closing body 10.
The removed buffer member 40 may be stored and stored in a predetermined storage location, or may be stored by being attracted to an object made of a magnetic material near the opening / closing device 1. Further, if the seat plate member 12 of the opening / closing body 10 is made of a magnetic material such as a steel plate, the buffer member 40 can be adsorbed and stored on the lower end surface of the seat plate member 12 of the opening / closing body 10 in the fully opened state. is there.

Moreover, an example shown in FIG. 3 is mentioned as another mounting | wearing aspect.
In this mounting mode, in consideration of the structure of the opening / closing body 10, when the opening / closing body 10 is beaten by a strong wind, the contact between the opening / closing body 10 and the screen door a is particularly effectively prevented.
That is, normally, the opening / closing body 10 of the opening / closing device 1 such as a shutter device is suspended at the upper end side from the winding shaft 32, but the lower end side is only fitted on the guide rails 20, 20 on both sides. Accordingly, when the open / close body 10 in the closed state receives a strong wind, the lower end side of the open / close body 10 is squeezed more greatly than the upper end side of the open / close body 10.
Therefore, in the mounting mode shown in FIG. 3, the buffer member 40 is mounted in the vicinity of the lower end side of the opening / closing body 10 across the opening / closing body width direction.
According to this mounting mode, the lower end side of the opening / closing body 10 that is often crushed is brought into contact with the one vertical frame a1 of the screen door a via the buffer member 40. Therefore, the opening / closing body 10 is bent or fluttered by strong winds. Can be effectively reduced. Moreover, since the buffer member 40 is arranged across the opening / closing body width direction, even when one vertical frame a1 of the screen door a is not positioned at the center of the opening and is shifted in the width direction, the vertical frame The buffer member 40 can be brought into contact with a1.

  In addition, when the opening / closing body 10 is fully opened, the buffer member 40 can be stored in the storage case 31 together with the opening / closing body 10 wound around the winding shaft 32 as shown in FIG. Therefore, it is possible to prevent the buffer member 40 from impairing the appearance of the opening / closing body 10 or hindering the opening / closing operation of the opening / closing body 10.

Moreover, according to the said embodiment, the aspect which mounted | wore the opening / closing body opening / closing body opening direction with the buffer member 40 with respect to the opening / closing body 10, and the aspect which mounted | wore the opening / closing body width direction with respect to the opening / closing body 10 However, as another mounting mode, it is mounted on the opening / closing body 10 in an obliquely mounted manner on the opening / closing body 10 or in a state where the buffer member 40 is bent in a curved shape such as a substantially S shape as shown in FIG. It is also possible to do.
In particular, according to the mounting mode shown in FIG. 6, the shock-absorbing effect over the entire opening / closing body 10 is good because the buffer member 40 is mounted on the opening / closing body 10 in a wider area.
When the buffer member 40 is used in this mounting mode, it is preferable to form the detachable portion 41 from a more flexible material so that it can be easily bent and deformed.

In addition, according to the said embodiment, although the attachment / detachment part 41 was comprised from the magnet which has elasticity, as another example, a magnet with rigidity, steel material with magnetism, a hard rigid resin material, and a magnet are integrated. The attaching / detaching portion 41 may be made of a rigid material. According to this configuration, the opening / closing body 10 can be prevented from being bent or fluttered due to the strong wind or the like by the rigidity of the detachable portion 41.
Moreover, if the attachment / detachment portion 41 is configured to include a material having vibration damping performance such as a vibration damping steel plate, the vibration damping effect during strong winds can be further improved.

  In addition, according to the example shown in FIGS. 2 and 3, the opening / closing body 10 is configured so that the recess 11a1 of the slat 11a faces the outdoor side, but as another example, the recess 11a1 faces the indoor side. May be. In this other example, when the buffer member 40 is mounted, the attaching / detaching portion 41 of the buffer member 40 is magnetically attracted to the opening / closing body 10 so as to straddle the recess 11a1. Therefore, also in this other example, the wearability is good, and there are substantially the same effects as the example shown in FIGS. 2 and 3.

  Moreover, according to the said embodiment, although each of the attachment / detachment part 41 and the elastic part 42 was each comprised integrally, you may comprise any one from a some member. For example, a configuration in which the elastic portion 42 composed of a plurality of members arranged in the longitudinal direction of the detachable portion 41 is integrated with the integral detachable portion 41, or an integral elasticity of the detachable portion 41 composed of a plurality of members. It is also possible to have a configuration in which the portion 42 is integrated.

  Moreover, according to the said embodiment, although the example provided with the one buffer member 40 with respect to the one opening-and-closing body 10 is shown, you may make it provide the some buffer member 40 with respect to the one opening-and-closing body 10. FIG. Good.
