Description

  The present invention relates to a joinery, and more particularly, to a joinery including a speed reduction device for reducing the opening and closing speed of a face member supported by a frame.

Conventionally, in a fitting such as a sliding door provided with a frame body and a face material, frictional resistance is obtained by slidingly contacting a braking member provided on the upper frame (aquarium) of the frame body and an abutting member provided on an upper edge of the face material. Has been proposed to reduce the moving speed when closing the face material (see, for example, Patent Document 1).
In the braking device described in Patent Document 1, a braking member is provided corresponding to the closed position of the face material, and the sliding contact member of the contact member is brought into sliding contact with the braking member during the closing operation of the face material. As a result, the face material can be decelerated, the impact sound at the time of closing can be weakened, and pinching of fingers can be avoided.

Japanese Patent No. 3423180

  However, the conventional braking device has only a mechanism for decelerating when the face material is completely closed, and in a state where the braking member and the contact member are not in sliding contact, that is, in a state where the face material is released to some extent, The opening / closing speed of the face material cannot be reduced. In addition, since the frictional resistance (dynamic friction coefficient) between the braking member and the abutting member is constant, when the face material in the open state is vigorously closed, the speed cannot be sufficiently reduced. There is also a possibility that a large impact sound is generated. On the other hand, although it is possible to decelerate the face material more strongly by increasing the frictional resistance between the braking member and the abutting member or extending the sliding contact distance by lengthening the braking member, in that case However, there is a problem that the opening / closing operation of the face material becomes heavy and the convenience is impaired. Further, in the conventional braking device, when a mechanism for changing the frictional resistance according to the closing speed of the face material is added, for example, a mechanism for changing the distance between the pair of sliding members in the contact member, the structure of the device is obtained. Inconveniences such as becoming complicated and large.

  An object of the present invention is to provide a joinery including a reduction gear that can reliably reduce the speed of a face member with a simple structure while ensuring good convenience.

  The joinery of the present invention includes a frame, a face member supported by the frame so as to be freely opened and closed, a speed reducer provided on one of the frame and the face member and capable of decelerating the face member by contacting the other. The reduction gear includes a device main body fixed to one of the frame and the face material, and is rotatably supported by the device main body and is attached to the other of the frame and the face material. A rotation member that can roll along, and the apparatus body includes a support portion that supports the rotation member so as to be movable at least in the opening and closing direction of the face material including a predetermined position, and toward the predetermined position. A biasing portion that biases the rotating member; and a contact portion that cannot contact the rotating member at the predetermined position and can contact the rotating member moved from the predetermined position. It is characterized by.

  Here, the joinery of the present invention may be a doorway joinery such as a sliding door, or may be a window such as a sliding window or a sliding window. Furthermore, the opening / closing type of the joinery is not limited to the sliding door open / closed type, but may be a vertical sliding open / closed type such as a raising / lowering window. It may be of a swing (rotating) opening / closing type such as a window.

  According to the present invention described above, in the speed reducer, the rotating member is movably supported by the support portion of the apparatus body, and the face member is opened and closed by urging the rotating member toward the predetermined position by the urging portion. Accordingly, when the rotating member rolls along the other of the frame body and the face material, the rotating member that receives the frictional resistance accompanying the rolling moves with respect to the apparatus main body. If the rotating member that has moved against the urging force from the urging portion comes into contact with the abutting portion, a frictional resistance is generated between the rotating member and the abutting portion, thereby stopping the rotation of the rotating member. Sliding along the other of the frame and the face material, or the rotational speed of the rotating member is reduced to increase the frictional resistance accompanying rolling, and the opening and closing speed of the face material is reduced. . The amount of movement of the rotating member relative to the apparatus main body is small when the opening / closing speed of the face material is slow to some extent, and although the rotating member does not come into contact with the contact portion and the face material does not decelerate, When the opening / closing speed increases, the amount of movement increases, and the rotating member comes into contact with the abutting portion to exert a deceleration effect. Further, when the opening / closing speed of the face material increases, the rotating member strongly contacts the abutting portion to greatly reduce the speed. It is comprised so that an effect can be exhibited. Accordingly, since the deceleration effect can be varied according to the opening / closing speed of the face material, a large frictional resistance is not generated during normal use, and the face material can be decelerated when suddenly opened and closed. Therefore, the face material can be surely decelerated without impairing convenience.

In this case, in the joinery of the present invention, the frame body is configured to have an upper frame, and an upper rail is formed on the upper frame to guide the face material so that the face material can be slidably opened and closed. The upper edge is guided to the upper rail along the longitudinal direction of the upper frame, and the movement in the expected direction is restricted by the upper rail, and the reduction gear is in the expected direction at the upper edge of the face material. The apparatus main body is fixed to one side, and the rotating member is provided so as to roll along the surface of the upper frame, or the apparatus is disposed on the upper frame on one side in the prospective direction from the face material. It is preferable that the main body is fixed and the rotating member is provided so as to roll along a prospective direction one side surface of the upper end edge of the face member.
According to such a configuration, the upper body of the face material is guided in the opening and closing direction by the upper rail and the movement in the prospective direction is restricted, thereby fixing the apparatus main body to one side of the prospective direction of the upper edge of the face material. The rotating member is brought into contact with the upper frame or the rotating member from one side so that the apparatus main body is fixed to the upper frame on one side of the prospective direction from the face material and the rotating member is brought into contact with the upper edge of the face material. Even if they are brought into contact with each other, the rolling state of the rotating member can be maintained well. Therefore, since it is not necessary to arrange the rotating member so as to be sandwiched from both sides of the prospective direction of the face material from one side and the other side, the structure of the speed reducer can be simplified, the installation cost can be reduced, and the influence of wind and rain By installing the speed reducer on the side of a good environment such as the indoor side where it is difficult to be affected, the speed reduction effect can be reliably exhibited.

Furthermore, in the joinery of the present invention, the speed reducer has a rotating shaft that rotatably supports the rotating member with respect to the apparatus main body, and the support portion of the apparatus main body extends along the opening / closing direction of the face material. It is preferable that the long shaft is long and the rotation shaft is inserted through the long hole.
According to such a configuration, the rotating shaft that supports the rotating member is inserted into the long hole, and the rotating shaft is movably supported along the long hole, so that the support portion is configured with a relatively simple structure. be able to.

Further, in the joinery of the present invention, the urging portion of the apparatus main body has a pair of elastic pieces that can come into contact with the rotating shaft from both sides of the face material in the opening and closing direction to move the rotating member and the rotating shaft. It is preferable that the rotating member can be biased toward the predetermined position by the deformation of the elastic piece.
According to such a configuration, since it is not necessary to provide a separate spring member or the like by biasing the rotating member to a predetermined position with a pair of elastic pieces installed so as to sandwich the rotating shaft, it is relatively simple. The urging portion can be configured by the structure.

In the joinery of the present invention, the contact portion of the apparatus main body has a pair of contact protrusions that can contact the rotating member from both sides of the face member in the opening and closing direction, and the rotation moved from the predetermined position. It is preferable that the rotation of the rotating member can be decelerated by the member abutting against one of the abutting protrusions.
According to such a configuration, the amount of movement of the rotating member until contact and the contact area at the time of contact are compared with the case where the rotating member is brought into contact with the contact protrusion, as compared with the case of surface contact. It becomes easy to set strictly, the predetermined frictional resistance when the rotating member comes into contact with the contact projection can be generated exactly as set, and the deceleration effect can be more reliably exhibited.

Further, in the joinery of the present invention, the other of the frame body and the face material has a first rolling surface on which the rotating member can roll, and projects to one side in the prospective direction from the first rolling surface. A second rolling surface on which the rotating member can roll, and the second rolling surface has a predetermined length dimension from a position corresponding to at least one of a fully closed position and a fully opened position of the face material. Are preferably provided.
According to such a configuration, by providing the second rolling surface that protrudes from the first rolling surface, the first rolling surface when the rotating member rolls along the second rolling surface. The frictional resistance due to rolling is greater than in the case of, and a large deceleration effect can be exhibited. Furthermore, by providing a second rolling surface corresponding to the fully closed position or fully opened position of the face material, and setting the second rolling surface to a predetermined length dimension, a predetermined section or fully opened state before the fully closed state is set. In the previous predetermined section, a large deceleration effect can be exhibited, and the impact caused by the collision between the face material and the frame can be surely reduced.

Further, a mohair 115 that is slidable on the bathroom side surface of the upper rail 2 </ b> A is attached to the upper end undressing room side of the bathroom side finding piece 113. Further, a sliding member 17 guided by the upper rail 2A is attached to the upper end portions of the vertical rods 13 and 14, and thereby the upper ends of the upper rod 11 and the vertical rods 13 and 14, which are the upper edge of the shoji 10, are attached. The part is guided to the upper rail 2A along the longitudinal direction of the upper frame 2, and movement in the prospective direction is regulated by the upper rail 2A.

  The speed reduction device 30 is provided on the upper collar 11 of the shoji 10 which is one of the frame and the face material, and is provided so as to be able to contact the upper frame 2 of the joinery frame 6 which is the other. That is, as shown in FIGS. 4 to 6, the speed reducer 30 is found on the apparatus main body 31 that is fixed to the upper collar 11, and is rotatably supported by the apparatus main body 31 and is located on the dressing room side of the upper frame 2. A roller 32 that is a rotating member that can roll along the side surface of the undressing room of the surface portion 23 and the upper rail 2A, a rotating shaft 33 that rotatably supports the roller 32 on the apparatus main body 31, and the apparatus main body 31 11 and a screw 34 that is fixed to the head 11. Furthermore, the speed reduction device 30 has a liner member 35 fixed to the dressing room side surface 23 of the upper frame 2 and the dressing room side surface of the upper rail 2A. A first rolling surface is constituted by the side surface of the dressing room of the upper rail 2A, and a second rolling surface is constituted by the side surface of the liner member 35 projecting toward the prospective direction dressing chamber side from the first rolling surface. .

  The apparatus main body 31 is an integrally formed member made of resin and fixed to the side surface of the dressing chamber side of the upper collar 11 as one side in the prospective direction at the upper edge of the face material, and the upper end of the dressing chamber side finding piece 114 of the upper collar 11. An engagement piece 311 that engages with each other, an upper surface portion 312 that supports the shaft head portion 331 of the rotation shaft 33, a support surface portion 313 that supports the shaft tip portion 332 of the rotation shaft 33, and the upper surface portion 312 and the support surface portion. 313 and a cover portion 314 that covers the periphery of the roller 32. The apparatus main body 31 is formed with an accommodation space 36 that is surrounded by the upper surface portion 312, the support surface portion 313, and the cover portion 314 and opens toward the bathroom side (the other side in the prospective direction). And a part of the roller 32 protrudes from the opening of the accommodation space 36 toward the bathroom. The roller 32 is made of a member having an appropriate elasticity and friction coefficient such as soft rubber, and is in contact with the undressing room side finding surface portion 23 of the upper frame 2 and the unloading room side surface of the upper rail 2A, and opens and closes the shoji 10 It is comprised so that it may roll with.

  In the apparatus main body 31 described above, the shaft head 331 of the rotary shaft 33 is inserted into the upper surface portion 312, and the shaft head 331 is opened and closed in the opening / closing direction of the shoji 10 (the direction indicated by the arrow X in FIGS. 5 to 7). ), And a shaft tip portion 332 of the rotary shaft 33 is inserted into the support surface portion 313. The shaft tip portion 332 extends along the opening / closing direction of the shoji 10. A second elongate hole 316 that can be guided is formed. A C-ring 333 having a diameter larger than the width of the second long hole 316 is engaged with the shaft tip portion 332 on the lower side of the support surface portion 313 so that the rotating shaft 33 does not come out upward. Accordingly, the first and second elongated holes 315 and 316 form a support portion of the apparatus main body 31, and the rotation shaft 33 is guided to these elongated holes 315 and 316, so that the roller 32 can open and close the shoji 10. It is supported so as to be movable and rotatable. Note that the inner peripheral surface of the cover portion 314 is formed to be larger than the diameter of the roller 32 by a predetermined dimension, so that the roller 32 does not contact the cover portion 314 at all times and the rotation and movement of the roller 32 are not restricted. It has become.

  Further, below the first elongated hole 315 in the upper surface portion 312 of the apparatus main body 31, as shown in FIGS. 6 and 7, a pair of elastic pieces 317 as an urging portion and a space between these elastic pieces 317 are provided. A protrusion 318 is formed. The pair of elastic pieces 317 are formed as projecting pieces protruding from the dressing room side toward the bathroom side, can contact the lower surface of the shaft head 331 of the rotating shaft 33, and sandwich the shaft portion 334 of the rotating shaft 33. The sliding door 10 is configured to be able to contact the shaft portion 334 from both sides of the opening / closing direction of the shoji 10. When these elastic pieces 317 are guided by the long holes 315 and 316 and the rotary shaft 33 moves, the elastic pieces 317 on one side are elastically deformed as shown in FIG. The roller 32 is urged toward a predetermined position shown in FIG. Further, the protruding portion 318 is formed to protrude from the dressing room side toward the bathroom side, and by contacting the lower surface of the shaft head 331 of the rotating shaft 33, the movement of the rotating shaft 33 in the axial direction is restricted, and the protrusion The tip of the portion 318 is brought into contact with the shaft portion 334 of the rotation shaft 33, so that the rotation of the rotation shaft 33 in a direction other than the opening / closing direction of the shoji 10 is restricted.

  Further, as shown in FIGS. 6 and 7, the inner peripheral surface of the cover portion 314 of the apparatus main body 31 is eccentric to the undressing room side from the rotating shaft 33 and is located on both sides in the opening / closing direction of the shoji 10. A pair of contact protrusions 319 are formed as contact portions that can contact the roller 32 from both sides in the opening / closing direction. These contact protrusions 319 are guided by the long holes 315 and 316 and the tip of the contact protrusion 319 on one side is brought into contact with the surface of the roller 32 as shown in FIG. By contacting, a frictional resistance is generated between the roller 32 and the rotation of the roller 32 is stopped, or the rotation speed of the roller 32 is reduced. If the rotation of the roller 32 is stopped by contacting the contact protrusion 319 in this way, the roller 32 slides along the dressing chamber side finding surface portion 23 of the upper frame 2 and the dressing chamber side surface of the upper rail 2A. The opening / closing speed of the shoji 10 is reduced. Alternatively, even when the rotation speed of the roller 32 is reduced due to contact with the contact protrusion 319, the friction of the roller 32 that rolls along the dressing chamber side finding surface portion 23 of the upper frame 2 and the dressing chamber side surface of the upper rail 2 </ b> A. The resistance increases, and the opening / closing speed of the shoji 10 is reduced.

In the above sliding door 1, the operation of the reduction gear 30 will be described in detail with reference to FIGS. Here, FIGS. 8 to 10 are cross-sectional views at the height position of the upper rail 2A.
First, as shown in FIG. 8, in a state where the shoji 10 is opened and closed at a normal (low speed) speed, the roller 32 of the speed reduction device 30 is located on the upper rail 2 </ b> A (and the dressing room side finding surface portion of the upper frame 2). 23) rolls along the dressing room side surface (the surface of the upper frame), but does not move significantly in the left-right direction with respect to the apparatus main body 31. That is, as shown in FIG. 7A, the roller 32 is positioned at a predetermined position (or in the vicinity of the predetermined position) in a state where the rotating shaft 33 is urged by the pair of elastic pieces 317, and the roller 32 comes into contact therewith. The protrusion 319 is not brought into contact with the protrusion 319. Therefore, although the rolling resistance of the roller 32 that rolls along the upper rail 2A acts, a large frictional resistance does not act, and the shoji 10 can be opened and closed with a relatively light force. When the shoji 10 is closed, as shown by a two-dot chain line in FIG. 8, the roller 32 gets over the liner member 35 and comes into contact with the step portion between the liner member 35 and the upper rail 2A. The closed state of the shoji 10 can be maintained by the resistance of the part.

  Next, as shown in FIG. 9, when the shoji 10 is opened and closed at a speed higher than usual, the roller 32 receives a large rolling resistance from the upper rail 2 </ b> A and moves in the direction opposite to the operation direction of the shoji 10. Will be. That is, as shown in FIG. 7 (B), the roller 32 moved with respect to the apparatus main body 31 is brought into contact with the contact protrusion 319 on one side, whereby a frictional resistance is generated, whereby the opening / closing speed of the shoji 10 is reduced. It is like that. Furthermore, when the closing operation to the vicinity of the closing position of the shoji 10 is performed, the upper edge of the shoji 10 is biased toward the dressing room by the roller 32 riding on the liner member 35 as shown in FIG. As a result, the rolling resistance of the roller 32 is further increased, so that the roller 32 comes into stronger contact with the contact protrusion 319, and the opening / closing speed is further reduced. At this time, the opening / closing speed of the shoji 10 is further reduced by the frictional resistance generated by pressing the mohair 115 of the upper arm 11 and the sliding member 17 of the vertical arm 13, 13 against the bathroom side surface of the upper rail 2A. ing. Therefore, the vertical saddle 13 of the shoji 10 does not strongly collide with the vertical frame 4 and the impact sound can be suppressed, and the roller 32 over the liner member 35 is locked to the stepped portion, so that the shoji 10 rebounds. Can also be suppressed.

According to the above embodiment, the following effects are obtained.
That is, when the moving amount of the roller 32 with respect to the device main body 31 in the speed reducer 30 changes according to the opening / closing speed of the shoji 10 and the opening / closing speed is somewhat slow, the roller 32 does not contact the contact protrusion 319 and opens / closes. As the speed increases, the roller 32 comes into contact with the contact protrusion 319 to exert a decelerating effect. Therefore, during normal use, it is possible to prevent a large frictional resistance without impairing convenience, and unexpectedly vigorously. When the opening / closing operation is performed, the shoji 10 can be decelerated to suppress an impact sound or the like. Further, by adopting a structure in which the rotating shaft 33 of the roller 32 is supported by the elongated holes 315 and 316 so as to be movable in the left and right directions and urged to a predetermined position by the pair of elastic pieces 317, the urging force of the elastic piece 317 is appropriately adjusted. By setting to, the relationship between the opening / closing speed and the movement amount of the roller 32 can be adjusted, and even if the speed reduction device 30 has a relatively simple structure, the speed reduction effect according to the speed of opening / closing the shoji 10 is exhibited. be able to.

In addition, this invention is not limited to the structure of the said embodiment.
For example, in the said embodiment, although the single door 1 for bathroom entrances was illustrated and demonstrated as joinery, the joinery of this invention is not restricted to what has one face material (paper shovel), Two or more sheets The face material may be supported in a single-drawing manner so that it can be freely opened and closed, or the two face materials are supported in a single-drawing type in opposite directions, and a draw-open type in which face material storage parts are formed on the left and right sides It may be. Furthermore, the joinery of the present invention is not limited to a joinery for a bathroom, and may be a joinery provided in an opening with the outdoors, or may be provided in another opening. Here, in the said embodiment, although the prospective direction one side was made into the prospective direction undressing room side and the prospective direction other side was made into the prospective direction bathroom side, if it is a fitting provided in the opening part with the outdoors, prospective direction One side may be the indoor side or the outdoor side, and the other side may be the outdoor side or the indoor side. If the fitting is provided between adjacent spaces (rooms, hallways, etc.), one side of the prospective direction Is one space side and the other side is the other space side, and the joinery of the present invention may be a sliding door or window, or may be a raising / lowering window. .
The joinery of the present invention is not limited to a slide opening / closing type, and may be of a swing (turning) opening / closing type such as a hinged door (door), a hinged window, a protruding window, and an interior fall window. Even in such a swing open / close type joinery, the same effect as described above can be obtained by providing the speed reducer at an appropriate position according to the rotation trajectory of the face material.

  Moreover, in the said embodiment, the reduction gear 30 was provided in the upper arm 11 of the shoji 10 which is one of a frame and a face material, and the roller 32 was made to contact | abut to the upper frame 2 of the joinery frame 6 which is the other. However, the present invention is not limited thereto, and the speed reduction device 30 may be provided on the upper frame 2 (opening frame side), and the roller 32 may be brought into contact with the upper collar 11 of the shoji 10. At that time, a position where the shoji 10 can always contact the roller 32 at any open / closed position is more preferable. For example, when the shoji 10 is in the fully closed position, such as a portion where the vertical bone 7 is located in the upper frame 2. A position facing the door bottom side is preferable. Furthermore, the lower frame 3 of the joinery frame 6 and the lower cage 12 of the shoji 10 may be set as one and the other, respectively, and the speed reducer 30 may be provided on the lower frame 3 or the speed reducer 30 may be provided on the lower cage 12.

  Furthermore, in the said embodiment, although the speed reducer 30 was provided in the dressing room side of the upper arm 11 of the shoji 10, and the roller 32 was made to contact | abut to the dressing room side side surface of the upper frame 2, it is not restricted to this, The reduction gear 30 may be provided on the bathroom side, or a pair of reduction gears 30 may be provided on both the dressing room side and the bathroom side. However, in the bathroom doorway fittings, it is preferable to provide the speed reduction device 30 on the dressing room side where it is difficult for water or the like to be applied, and in windows and the like, it is preferable to provide the speed reduction device on the indoor side that is not easily affected by wind and rain. Moreover, although the speed reducer 30 was provided in the undressing room side of the upper arm 11 of the shoji 10, and the roller 32 was made to contact | abut to the undressing room side surface of the upper frame 2, the axis | shaft which extends the roller 32 in an expected direction is used as an axis. You may make it contact | abut to the prospective surface (upper frame bottom face part 25, undressing room side prospective face part 22) of the upper frame 2 so that it can rotate as a core. Similarly, a speed reduction device 30 is provided on the upper frame 2 side, a roller 32 is rotatably provided with an axis extending in the expected direction as an axis, and an upper end surface of the upper collar 11 (a surface facing the expected surface of the upper frame 2). You may make it contact | abut.

  In the speed reduction device 30 of the above-described embodiment, the roller 32 is supported so as to be movable only in the opening / closing direction (X direction in FIGS. 5 to 7) of the shoji 10 with respect to the apparatus main body 31. The roller 32 only needs to be supported movably including at least the opening / closing direction of the shoji 10, that is, only to be supported so as to be movable in a plane including the opening / closing direction of the shoji 10 and the prospective direction. And when the roller 32 is supported movably in the prospective direction, it is preferable that a second urging portion for urging the roller 32 in the prospective direction is provided. For example, an elastic part may be provided instead of the protrusion 318 in the above-described embodiment, and the shaft part 334 of the rotating shaft 33 may be pressed to the bathroom side with this elastic part. Further, when the roller 32 is supported so as to be movable in the prospective direction, a second abutting portion capable of abutting on the roller 32 moved in the prospective direction is formed on the dressing room side of the inner peripheral surface of the cover portion 314. May be.

In the speed reduction device 30 of the above-described embodiment, the rotation of the roller 32 is reduced by bringing the roller 32 into contact with a portion (cover portion 314) located outside the roller 32.
