Japanese Utility Model Publication No. 5-42564 (FIGS. 1 to 3)

However, in the joinery described in Patent Document 1, a rotary oil damper is attached to the upper end of the face material, and a rack is attached in the vicinity of the rail of the upper frame, so that a rotary is provided between the face material and the upper frame. It was necessary to secure an installation space for installing the oil damper. For this reason, a design change such as extending the rail of the upper frame downward to increase the gap between the upper frame main body and the face material is required, and there is a problem that a normal frame body and face material cannot be used.
In addition, since the rotary oil damper is attached to the upper end of the face material, the damper becomes an obstacle when building (or removing) the face material rapidly, and the workability of the erection work is reduced. There is also a problem.

  An object of the present invention is to provide a fitting that does not require a design change of a frame body and a face material, can be retrofitted on-site, and can smoothly implement the face material.

  The joinery of the present invention is a joinery comprising a frame, at least one face member supported by the frame so as to be slidable to open and close, and a speed reducing means for reducing the opening and closing speed of the face member, The frame is provided with a cover portion that covers a part of the side surface of the face material, and the speed reduction means includes a first speed reduction member that exhibits a damping force by moving relative to each other within a predetermined speed reduction section, and a first speed reduction member. The first and second reduction members are covered with the cover portion, and one of the first and second reduction members is provided on a side surface of the face material, The other side is provided on the inner side of the cover part, the closed-side deceleration section from the fully closed position of the face material to a position where the face material is opened by a predetermined distance, and the face material from the fully open position of the face material. Decrease on the open side to the position closed by a predetermined distance Wherein the deceleration zone by at least one of sections is set.

Here, the speed reduction means may be composed of a conventional rotary oil damper (first speed reduction member) having a pinion gear and a rack (second speed reduction member) meshable with the pinion gear. May be composed of a linear motion damper (first reduction member) having a piston that reciprocates in a cylinder filled with and a member that abuts against (or pulls) the piston of the linear motion damper. . The mechanism for exerting the damping force is not limited to that due to the internal resistance of oil, but may be one that uses the movement resistance of a gas (air, etc.) or a liquid other than oil (water, etc.). An electromagnetic damper or the like for conversion may be used. Furthermore, a friction damper of a type that exhibits a damping force as a friction force when the first reduction member and the second reduction member are in sliding contact with each other can be used.
Further, as the face material, a shoji configured by inserting a plate material made of glass or resin into an interior in which the upper, lower, left, and right eaves are assembled four times, can be used. Alternatively, the face material may be made of a plate material made of wood, resin, or metal.

According to such a configuration, one of the first speed reduction member and the second speed reduction member of the speed reduction means is provided on the face material, and the other is provided on the cover portion of the frame body. Since relative movement occurs between the first deceleration member and the second deceleration member, the first deceleration member and the second deceleration member face material act on each other in the closed-side deceleration section or the open-side deceleration section to exert a damping force. The Therefore, the face material can be decelerated before the end of the opening or closing operation, and even when the face material is opened or closed vigorously, the moving speed of the face material is reduced to prevent collision with the frame. be able to.
Further, by providing one of the first and second speed reducing members on the side surface of the face material and providing the other inside the cover portion, the speed reduction device is provided between the upper end portion of the face material and the upper frame as in the prior art. Compared to the case of providing a frame, it is less likely to be restricted by the installation space, and it is not necessary to change the structure of the guide portion between the frame and the face material (rail, rail receiver, sliding piece, etc.). Thus, a speed reduction mechanism can be added by using a normal frame or a face material, providing a cover portion on the frame, and providing speed reduction means on the frame and the face material. Also, one or the other of the first and second reduction members is provided on either the inside of the cover portion that covers a part of the side surface of the face material or the side surface of the face material, that is, the speed reduction means is provided on the side of the face material. As a result, the speed reducer does not get in the way when building (or removing) the face material into the frame body in a fast manner, and the work can be carried out smoothly and workability can be maintained well. Further, by covering the first and second deceleration members of the deceleration unit with the cover portion, the deceleration unit is not exposed and the appearance of the joinery can be maintained well.

In the joinery of the present invention, the cover portion is configured to be detachable with respect to the frame body, and among the first reduction member and the second reduction member, the reduction member provided on the side surface of the face member is It is preferable to be configured to be detachable from the side surface of the face material.
According to such a structure, the cover part separate from the frame is attached to the frame, and the speed reduction member provided on the side of the face material of the first speed reduction member and the second speed reduction member is the face material. By attaching to the side surface, the reduction gear and the cover can be attached later to the joinery already installed in the building or the like, and a reduction mechanism can be added later. Further, when the speed reducer or the cover is damaged, it can be easily replaced.

In the joinery of the present invention, it is preferable that the first reduction member is constituted by a rotary damper having a pinion gear, and the second reduction member is constituted by a rack that can mesh with the pinion gear.
According to such a configuration, by providing one of the rotary damper and the rack on the face material and providing the other on the cover portion, the pinion gear and the rack mesh with each other in the closed-side deceleration section or the open-side deceleration section, A damping force is exhibited by the rotary damper. That is, since the speed reduction means is configured by a combination of a rotary damper and a rack, the speed reduction means can be made compact, and the cover portion covering the speed reduction means can also be made compact.

  In the joinery of the present invention, the rotary damper is composed of a one-way damper that exhibits a damping force only in one direction of rotation, and a closed-side one-way damper that exhibits a damping force that exhibits a damping force and different rotation directions. And an open side one-way damper, and the rack is composed of two racks, a closed side rack and an open side rack, and the closed side rack is a closed movement of the face material. In this case, the closed side one-way type damper is provided so as to be able to mesh with the pinion gear of the closed side one-way type damper so that the closed side one-way type damper rotates in the rotational direction in which the damping force is exhibited in the closed side deceleration section. The open-side one-way damper pinion gear is rotated so that the open-side one-way damper rotates in the rotation direction exhibiting the damping force within the open-side deceleration section during the opening movement of the face material. It is preferably provided so as to be engaged with.

According to such a configuration, in the closed side deceleration section, the closed side one-way damper pinion gear and the closed side rack mesh with each other, and the closed side one-way damper exhibits a damping force, and in the open side deceleration section, The open side one-way damper pinion gear meshes with the open side rack, and the open side one-way damper exerts damping force. With this, the face material can be decelerated and collision with the frame can be prevented.
In addition, since the rotary damper is a one-way type damper that exhibits damping force only in one direction of rotation, when the face material is opened and moved from the fully closed position of the face material, the face material is closed and moved from the fully opened position of the face material. When doing so, the rotary damper rotates in the non-damping force exerting rotation direction and does not exert the damping force, so that a smooth opening / closing operation can be ensured.

  In the joinery of the present invention, the rotary damper is composed of a unidirectional damper that exhibits a damping force only in one direction of rotation, and the rack is composed of two racks, a closed rack and an open rack, The closing rack is provided so as to be able to mesh with the pinion gear of the one-way damper so that the one-way damper rotates in the rotation direction in which the damping force is exhibited in the closing-side deceleration section when the face material is closed. The open side rack is provided on the opposite side to the closed side rack with respect to the slide movement central axis of the one-way damper, and the open side rack moves in the one direction within the open side deceleration section when the face material is opened. It is preferably provided so as to be able to mesh with the pinion gear of the mold damper.

According to such a configuration, the closed side rack is provided in the closed side deceleration section so that the one-way damper engages with the pinion gear in the rotational direction in which the damping force is exerted, and the open rack is provided as the center of sliding movement of the one-way damper. By providing the shaft on the opposite side of the closed rack, the unidirectional damper meshes with the pinion gear in the same direction as the rotational direction in which the damping force is exerted in the closed deceleration section in the open deceleration section. The surface material can be decelerated by either one of the closing operation and the opening operation of the surface material by one unidirectional damper. Moreover, when it comprises with two one-way type | mold dampers, the one-way type | mold damper of the same damping force display rotation direction can be used, and a common component can be aimed at.
In addition, since the rotary damper is a one-way type damper that exhibits damping force only in one direction of rotation, when the face material is opened and moved from the fully closed position of the face material, the face material is closed and moved from the fully opened position of the face material. When doing so, the rotary damper rotates in the non-damping force exerting rotation direction and does not exert the damping force, so that a smooth opening / closing operation can be ensured.

It is preferable that the fitting of the present invention is provided at the entrance and exit of the bathroom and the dressing room, and the cover portion and the speed reduction means are provided on the dressing room side of the face material.
According to such a configuration, even in the case of a joinery generally made of a light weight face material such as a bathroom doorway, the moving speed of the face material is reduced by the reduction means to prevent a collision with the frame body. It is possible to make it difficult to damage the face material and the frame.
Moreover, even in the case of a joinery that generally employs a lower door system such as a bathroom doorway, one of the first and second reduction members is provided on the side of the face material, and the other is provided on the inner side of the cover part. Thereby, it can be made hard to receive the restriction | limiting of the installation space of a reduction gear device by the space between the upper end part of a face material and an upper frame being small.

Similar to the first embodiment, the rotary oil damper 13 is configured to absorb the rotational energy of the rotating shaft portion in the counterclockwise rotation direction (the damping force exerting rotation direction) of the arrow A (FIG. 11). . In the clockwise rotation direction of arrow B (non-damping force exerting rotation direction), the rotary oil damper 13 is configured not to act.
In such a configuration, when the sliding door 3 is closed, the pinion gear 12 and the closing rack 11A are engaged with each other in the closing-side deceleration section L2, and the pinion gear 12 rotates counterclockwise as indicated by the arrow A (damping). The sliding door 3 decelerates. Further, even when the sliding door 3 is moved to open, the pinion gear 12 and the open side rack 11B are engaged in the open side deceleration section L4, and the pinion gear 12 rotates counterclockwise as indicated by the arrow A (damping force). The sliding door 3 decelerates.

According to the present embodiment, there are the following effects in addition to the effects described above.
(3-1) In both cases of the opening operation and the closing operation, the sliding door 3 is decelerated by the reduction gear 10C. Therefore, when the sliding door 3 is operated with an excessive operation force, the sliding door 3 is vigorously moved vertically. It is possible to prevent collision with the frames 23 and 24 and improve operability.

(3-2) Since the sliding door 3 can be decelerated in both the opening and closing operations by the single rotary oil damper 13, the number of parts constituting the decelerator 10C can be reduced. However, two rotary oil dampers 13 may be provided. In that case, it is sufficient to use two dampers (common dampers) having the same rotational direction of the damping force, and the number of parts can be reduced. It is possible to prevent misplacement of parts.
