Description

  The present invention relates to a joinery having a frame that forms an opening, and a shoji that is movably provided along the frame and can close the opening.

  A joinery having a function to prevent the shoji from closing forcefully exists among joinery having a shoji that is provided movably along the frame and can close the opening (see, for example, Patent Document 1). In such a joinery, for example, magnets are provided on the left and right end sides of the upper horizontal frame, and on the upper arm of the shoji, a magnet is provided on the door end side and a member that can swing in the vertical direction is provided. It has been. The swingable member on the shoji side projects upward from the upper arm when the shoji is opened, and when the shoji is closed at a speed slower than a predetermined speed, Due to the repulsion between the magnet of the member and the magnet on the frame side, the swinging member swings downward and is accommodated in the upper arm, and the door toe reaches the vertical frame and the shoji is closed. On the other hand, when the shoji is closed at a speed faster than a predetermined speed, the swinging member on the shoji side will soon be repelled by the magnet, and the swinging member will pass under the magnet while protruding upward. By abutting against a stopper provided on the upper frame, it is configured to stop in a state where the shoji is opened before the door toe reaches the vertical frame.

JP 2009-57737 A

  However, in the joinery as described above, when the shoji is open, the member protruding above the upper arm swings downward due to the repulsive force of the magnet, and the shoji can be closed. When the sag drops, the swinging member remains in a state of protruding upward from the upper eyelid, and there is a problem that the shoji cannot be closed.

  This invention is made | formed in view of this subject, The place made into the objective is to provide the fitting which can stop the movement of a shoji according to the moving speed of a shoji.

In order to achieve such an object, the joinery of the present invention includes a frame that forms an opening, a shoji that is movably provided along the frame, and that can close the opening, and the shoji that is provided on the shoji. A restriction that protrudes toward the frame body from the heel of the shoji when moving at a predetermined speed or more, and a restriction that restricts movement of the shoji by contacting the projecting portion provided on the frame body. And a joinery characterized by having a portion.
According to such a joinery, the protruding portion protrudes when the shoji moves at a predetermined speed or more, and the protruding protrusion comes into contact with the restricting portion to stop the shoji. Therefore, the shoji has reached the predetermined speed or more. It is possible to stop the movement of the shoji. Further, when the predetermined speed is not reached, the projecting portion does not project and thus does not contact the regulating portion. For this reason, when the predetermined speed is not reached, the shoji can be reliably closed.

The fitting is a first rotating body that rotates when the shoji moves by contacting with the frame, and rotates coaxially with the rotation axis of the first rotating body and rotates together with the first rotating body. A second rotating body whose outer diameter expands due to centrifugal force generated at the time, and the second rotating body in a state before the outer diameter of the second rotating body expands, provided so as to be rotatable around the rotating shaft. A peripheral surface facing member having an inner peripheral surface facing the outer peripheral surface of the body at an interval from each other, and the protruding portion is formed by projecting a part of the outer peripheral portion of the peripheral surface facing member to the outside. When the shoji moves at the predetermined speed or more, the outer diameter of the second rotating body widens, and the outer peripheral surface of the second rotating body moves the inner peripheral surface of the peripheral surface facing member. By pressing, the peripheral surface facing member rotates together with the second rotating body, and the protruding portion It is desirable to protrude.
According to such a joinery, the outer diameter of the second rotating body that rotates coaxially with the first rotating body that rotates when the shoji moves in contact with the frame body increases due to the centrifugal force generated by the rotation. By pressing the circumferential surface facing member, the second rotating body and the circumferential surface facing member rotate together. At this time, the protruding portion provided on the peripheral surface facing member protrudes toward the frame body side from the heel of the shoji. Thus, since the 1st rotary body and the 2nd rotary body which rotate with the movement of a shoji rotate based on the moving speed of a shoji, in order for a 2nd rotary body to expand an outer diameter with a centrifugal force The shoji needs to move at a predetermined speed or higher. For this reason, when the shoji is at a predetermined speed or higher, the protruding portion protrudes and the movement is restricted, and when it is lower than the predetermined speed, it is possible to provide a fitting that is not restricted.

In such a joinery, it is desirable that the shoji be provided with a rotation stop portion that stops the rotation of the peripheral surface facing member in a state where the protruding portion protrudes.
According to such joinery, since the rotation stop portion is provided, the rotation of the circumferential surface facing member is rotated at the position where the rotation of the rotated circumferential surface facing member is stopped by the rotation stopping portion and the protruding portion is projected. It is possible to stop.

In such a joinery, it is preferable that the protruding protruding portion is brought into contact with the restricting portion before the opening is closed by the shoji.
According to such a joinery, the projecting protruding portion comes into contact with the restricting portion before the shoji closes the opening. Therefore, the shoji can be stopped before the opening is completely closed by the shoji.

In such a joinery, it is desirable that the protruding portion is sandwiched between the rotation stop portion and the restricting portion to restrict the movement of the shoji.
According to such a joinery, since the protrusion is sandwiched between the rotation stop portion and the restricting portion and the movement of the shoji is restricted, the movement of the shoji can be surely restricted.

In such a joinery, it is preferable that the restricting portion includes a cushioning material that suppresses an impact when the protruding portion comes into contact with the fitting.
According to such a joinery, the restricting portion includes a cushioning material that suppresses an impact when the protruding portion comes into contact, so that the shoji moves at a predetermined speed or more and the protruding portion comes into contact with the restricting portion. Even so, the impact can be suppressed.

  It is desirable for the fitting to include a biasing member that biases the protruding protrusions to the inside of the shoji.

 When the rotation of the circumferentially opposed member stops, the rotation of the first rotating body and the second rotating body that are integrated with the outer diameter widening is also stopped, or the rotation speed is lowered. At this time, since the centrifugal force acting on the second rotating body is reduced, the outer diameter of the second rotating body is reduced, and when the second rotating body is separated from the circumferential surface facing member, the circumferential surface facing member is The force to move the protruding part to the frame side from the heel of the shoji stops. For this reason, when it has an urging member that urges the protruding part to the inside of the shoji as in the above-mentioned fitting, when the speed of the shoji becomes slower than a predetermined speed, the projecting part is quickly inserted into the shoji. It is possible to move it inside.

In this fitting, the biasing member projects the protruding portion that protrudes toward the frame body from the saddle of the shoji and is not in contact with the restricting portion when the speed of the shoji becomes slower than the predetermined speed. It is desirable to move to the shoji side.
According to such a joinery, when the outer peripheral surface of the second rotating body is separated from the inner peripheral surface of the peripheral surface facing member, the protrusion is moved to the shoji side, so the outer peripheral surface of the second rotating body is When moving away from the inner peripheral surface of the peripheral surface facing member, that is, when the speed of the shoji is lower than the predetermined speed, the projecting portion is moved to the shoji side by the urging member, so that the projecting portion is brought into contact with the regulating portion. The shoji will never stop.

Hereinafter, a fitting according to an embodiment of the present invention will be described with reference to the drawings.
As shown in FIGS. 1 and 2, for example, the joinery 1 of the present embodiment is provided with a frame 10 that forms an opening and is rectangularly framed, and is movable along the frame 10, and closes the opening. It is a draw-type joinery 1 having a possible shoji 12. In FIG. 1, the shoji is omitted.

  In the following description, when the joinery 1 attached to a building or the like is viewed from the outdoor side, the vertical direction is the vertical direction, the horizontal direction is the horizontal direction or the finding direction, and the depth is the indoor / outdoor direction. The direction is shown as the prospective direction. Further, each member included in the joinery 1 will be described by specifying the direction in the depth direction, the left-right direction, and the up-down direction when attached to a building or the like even if it is a single unit.

  When the shoji 12 is moved at a predetermined speed or higher when the shoji 12 is closed, the joinery 1 moves vertically with the door toe 12a before the door toe 12a comes into contact with the vertical frame 10a, that is, before it is closed. A shoji stop mechanism 20 is provided to stop the shoji 12 at a position spaced from the frame 10a by an appropriate distance, for example, about 75 mm. The shoji stop mechanism 20 is provided between the inner shoji (not shown) and the outer shoji 12 and the frame 10, but the outer shoji stop mechanism 20 and the inner shoji stop mechanism have the same configuration. Here, the shoji stop mechanism 20 for stopping the outer shoji will be described as an example.

  As shown in FIGS. 1 to 5, the shoji stop mechanism 20 includes a stop unit 21 provided on an outer shoji 12 (hereinafter referred to as an external shoji), and a roller 22 provided on the upper frame 10 b and included in the stop unit 21. And a stopper 52 against which the protruding portion 26d of the stop unit 21 comes into contact. Here, in FIG.1 and FIG.3, the position of the door rod 12a and the summoning rod 12b when the shoji 12 is closed is shown with the dashed-dotted line.

  The stop unit 21 is attached to the upper end side of the summoning bowl 12b of the shoji 12 on the side opposite to the door-end fence 12a.

  The stop unit 21 is in contact with a contact member 50 provided on the upper frame 10b, and a roller 22 as a first rotating body that rotates when the shoji 12 moves, a relay shaft 24 that forms a rotation axis of the roller 22, An inertial body 25 as a second rotating body having a shaft portion 25a that rotates coaxially with the roller 22 and is connected to the relay shaft 24, and an inertial body that is rotatably provided around the relay shaft 24 and the shaft portion 25a. 25, a unit main body 27 having a peripheral surface opposing member 26 provided so as to surround 25, an accommodating portion 27a that is fixed to the summing bar 12b and in which the inertial body 25 and the peripheral surface opposing member 26 are accommodated, and provided in the accommodating portion 27a. A lid member 28 that covers the upper portion of the accommodating portion 27a in which the inertial body 25 supported by the bearing portion 27b on the lower side of the shaft portion 25a and the circumferential surface facing member 26 provided so as to surround the inertial body 25 are accommodated; Have There.

  The stop unit 21 is coupled to the shaft portion 25a of the inertial body 25 while the inertial body 25 and the circumferentially opposed member 26 are accommodated in the accommodating portion 27a of the unit main body 27 attached to the summing bowl 12b. The relay shaft 24 is supported by the bearing portion 27 b of the unit main body 27 and the bearing portion 28 a of the lid member 28 and is provided rotatably. The roller 22 is provided on the upper shaft portion 24 a of the relay shaft 24 protruding upward from the lid member 28. Is fixed. Here, the relay shaft 24 and the shaft portion 25a are coupled so that power is transmitted without slipping. For this reason, when the roller 22 rotates, the inertial body 25 connected via the relay shaft 24 is also configured to rotate integrally in the accommodating portion 27a.

  The inertia body 25 includes a shaft portion 25a, an annular body 25b surrounding the shaft portion 25a, and an elastic member that presses the annular body 25b toward the shaft portion 25a. The annular body 25b is a disk-shaped member made of three metal parts manufactured by die casting. The three parts have a shape in which the annular body 25b is radially divided into three equal parts. When the three members are combined and arranged in an annular shape, the diameter of the hole formed in the center is formed so as to substantially match the diameter of the shaft portion 25a.

  An annular groove 25d that is recessed toward the shaft 25a is formed at the center in the axial direction on the outer peripheral surface 25c of the annular body 25b. An annular elastic member is attached to the groove 25d. The elastic member is, for example, an annular coil spring 25e, and the inner diameter of the ring formed by the coil spring 25e is slightly smaller than the diameter formed by the bottom of the groove 25d.

  The inertial body 25 includes an annular body 25b made up of three divided parts around the shaft portion 25a, and the inertial body 25 3 of the annular body 25b by the elastic force of the coil spring 25e provided in the groove 25d of the annular body 25b. Two parts are pressed against the shaft portion 25a.

  The circumferential surface facing member 26 is a cylindrical tube having an inner circumferential surface 26a that is opposed to the outer circumferential surface 25c of the annular body 25b of the inertial body 25 with a slight gap in the assembled state of the stop unit 21. And a protruding portion 26d protruding outward from a part of the outer peripheral portion of the cylindrical wall portion 26b. The circumferential surface opposing member 26 is formed to be rotatable on the outside of the inertial body 25, and when the rotated inertial body 25 has its outer diameter expanded by centrifugal force, the outer circumferential surface 25c of the annular body 25b is a circumferential surface. The inner circumferential surface 26 a of the facing member 26 is pressed, and the circumferential surface facing member 26 rotates around the relay shaft 24 together with the annular body 25 b. Therefore, a friction material 26c is provided on the inner peripheral surface 26a of the peripheral surface facing member 26 in order to prevent the outer peripheral surface 25c of the annular body 25b from slipping.

  The housing portion 27 a of the unit main body 27 includes an arcuate peripheral wall portion 27 c that is larger than the outer peripheral portion of the accommodated circumferential surface facing member 26 and a protruding portion 26 d of the circumferential surface facing member 26. And an open portion 27d that serves as a movement region of the protruding portion 26d that moves along with this. That is, the end portion 27e of the peripheral wall portion 27c forming the accommodating portion 27a functions as a rotation stop portion of the protruding portion 26d that moves when the peripheral surface facing member 26 rotates.

  Further, the unit main body 27 has a leaf spring 29 as an urging member for urging the protruding portion 26d of the rotating peripheral surface facing member 26 toward the shoji 12 side. The leaf spring 29 has a flat plate shape and is provided from one end portion 27e of the peripheral wall portion 27c toward the open portion 27d side. And the leaf | plate spring 29 will be in a flat state in the state which the protrusion part 26d of the circumferential surface opposing member 26 where the centrifugal force of the inertial body 25 does not act is located in the shoji 12 side, and the circumferential surface opposing member 26 will be in a state by centrifugal force. The leaf spring 29 is bent by the protruding portion 26d that rotates and acts to move the protruding portion 26d toward the shoji 12 side.

  The stopper 52 is fixed in the upper frame 10b between the outdoor wall portion 10c that forms a space in which the upper collar 12c of the shoji 12 is accommodated and the rail 10d. When the protrusion 52d protrudes from the shoji 12 toward the frame body 10 when the stopper 52 is moved in the closing direction of the shoji 12, the door toe 12a of the shoji 12 and the vertical frame 10a are appropriately spaced ( In the present embodiment, the protruding portion 26d is disposed so as to abut at a position where the shoji 12 stops with a distance of about 75 mm). Moreover, when the protrusion part 26d is located in the shoji 12 side, it is comprised so that the protrusion part 26d and the stopper 52 may not interfere.

  The contact member 50 is provided on the side surface on the indoor side of the rail 10d, so that when the roller 22 of the stop unit 21 provided in the shoji 12 comes into contact, the roller 22 is difficult to slip and easily rotates by the movement of the shoji 12. It is the member provided in. The contact member 50 has a length that is about 1/3 of the range in which the shoji 12 shoji can move, and is provided along the direction of finding, and when the projecting portion 26 d comes into contact with the stopper 52, It is provided so that it may contact on the opposite side to the door-end fence 12a from the contact position. Further, the contact member 50 can move in the expected direction between the guide portions 12d when the rail 10d is inserted into the space formed by the guide portions 12d provided on the upper collar 12c of the shoji 12 In addition, the roller 22 and the contact member 50 are configured not to be separated when they come into contact with the roller 22 of the stop unit 21.

Next, the movement of the shoji 12 and the operation of the shoji stop mechanism 20 will be described.
First, it is assumed that the shoji 12 is opened so that the door toe 12a of the shoji 12 is located more than 75 mm away from the vertical frame 10a. At this time, since the shoji 12 is not moved, the roller 22 and the inertial body 25 are shown in FIG. 6A regardless of whether the roller 22 is in contact with the contact member 50 or not. The peripheral surface facing member 26 stops, and the protruding portion 26d is located on the side of the shoji 12 without projecting from the indoor side surface of the bag of the shoji 12 to the indoor side.

  Then, it is assumed that the operator moves the shoji 12 to the vertical frame 10a side in order to close the shoji 12. At this time, when the roller 22 is not in contact with the contact member 50, the shoji 12 moves without the roller 22 rotating until the roller 22 contacts the contact member 50. When the roller 22 comes into contact with the contact member 50, the roller 22 starts to rotate as the shoji 12 moves. At this time, the inertia body 25 connected via the roller 22 and the relay shaft 24 also rotates together. Further, when the shoji 12 starts to move, the centrifugal force generated by the rotation of the inertial body 25 is caused by the biasing force of the coil spring 25e that biases the three parts of the annular body 25b included in the inertial body 25 toward the shaft portion 25a. Since it is small, the three parts rotate together with the shaft portion 25 a and the roller 22 as shown in FIG. That is, the outer diameter of the annular body 25b is not widened, and the outer peripheral surface 25c of the annular body 25b is separated from the inner peripheral surface 26a of the peripheral surface opposing member 26. Therefore, even if the roller 22 and the inertial body 25 rotate. The peripheral surface facing member 26 is stopped by the leaf spring 29 in a state where the protruding portion 26d is disposed on the shoji 12 side.

  Thereafter, when the moving speed of the shoji 12 exceeds a predetermined speed, the centrifugal force generated by the rotation of the inertial body 25 urges the three parts of the annular body 25b included in the inertial body 25 toward the shaft portion 25a. It becomes larger than the urging force of 25e, and the three parts move in the direction opposite to the shaft portion 25a, and the outer diameter of the annular body 25b increases. At this time, the outer circumferential surface 25c of the expanded annular body 25b presses the friction material 26c on the inner circumferential surface 26a of the circumferential surface facing member, so that the circumferential surface facing member 26 and the annular body 25b are integrated. The integrated circumferential surface facing member 26 and the annular body 25b try to rotate in the same direction as the roller 22, but the protruding portion 26d of the circumferential surface facing member 26 is urged toward the shoji 12 by the leaf spring 29. Therefore, when the force that causes the protruding portion 26d due to the rotation of the circumferential surface opposing member 26 and the annular body 25b to protrude toward the frame body 10 from the flange becomes greater than the urging force of the leaf spring 29, the circumferential surface opposing member 26 The protrusion 26d starts to rotate and starts to protrude toward the frame body 10 from the upper collar 12c.

  When the moving speed of the shoji 12 is maintained at a predetermined speed or more, as shown in FIG. 6 (c), the protruding portion 26d continues to move while protruding toward the frame 10, and FIG. 6 (d) shows. Thus, the protrusion 26d comes into contact with the stopper 52 provided on the upper frame 10b, and the shoji 12 stops. At this time, when the shoji 12 is stopped, the rotation of the roller 22, the inertial body 25, and the circumferential surface facing member 26 is stopped. That is, since the speed of the shoji 12 is slower than the predetermined speed, the three parts of the annular body 25b included in the inertial body 25 are moved to the shaft portion 25a side by the urging force of the coil spring 25e, and the outer peripheral surface 25c of the annular body 25b is surrounded. It leaves | separates from the internal peripheral surface 26a of the surface opposing member 26. FIG. For this reason, when the protruding portion 26d is brought into contact with the stopper 52 and the shoji 12 stopped is moved slightly in the opening direction, the projecting portion 26d is moved toward the shoji 12 by the urging force of the leaf spring 29. And the shoji 12 is closed by moving the shoji 12 to the vertical frame 10a side.

  On the other hand, when the shoji 12 is closed slowly and the moving speed of the shoji 12 is lower than a predetermined speed, the centrifugal force generated by the rotation of the inertial body 25 is smaller than the urging force of the coil spring 25e, so that the protruding portion 26d becomes the shoji. Since the state located on the 12 side is maintained, the shoji 12 is closed by continuing to move the shoji 12 as it is.

  That is, the predetermined speed is determined by the centrifugal force generated by the movement of the shoji 12, the biasing force that biases the three parts of the annular body 25b toward the shaft portion 25a by the coil spring 25e, and the protrusion 26d by the rotation of the peripheral surface facing member 26. Can be set as appropriate depending on the balance between the force to move the frame 10 toward the frame body 10 and the urging force of the leaf spring 29. For example, it is assumed that a hand or a finger is sandwiched between the vertical frame 10a and the door toe 12a. However, it is desirable to set the speed so that there is no hindrance or the speed at which the shoji 12 stops when a hand or finger is sandwiched between the vertical frame 10a and the door toe 12a.

  According to the joinery 1 of this embodiment, when the shoji 12 moves at a predetermined speed or more, the projecting portion 26d projects, and the projecting projecting portion 26d comes into contact with the stopper 52 and the shoji 12 stops. The movement of the shoji 12 can be stopped when the speed becomes equal to or higher than the predetermined speed. Further, when the predetermined speed is not reached, the protruding portion 26d does not protrude and does not contact the stopper 52. For this reason, when the predetermined speed is not reached, the shoji 12 can be reliably closed.

  In addition, the inertial body 25 that rotates coaxially with the roller 22 that rotates by the movement of the shoji 12 in contact with the frame body 10 expands the outer diameter due to the centrifugal force generated by the rotation, and the peripheral surface facing member 26 By pressing, the inertial body 25 and the peripheral surface facing member 26 rotate together. At this time, the protruding portion 26 d provided on the circumferential surface facing member 26 protrudes toward the frame body 10 from the upper collar 12 c of the shoji 12. For this reason, since the roller 22 and the inertial body 25 that rotate with the movement of the shoji 12 rotate based on the moving speed of the shoji 12, the outer diameter of the annular body 25b is increased by centrifugal force. Must move at a predetermined speed or higher. For this reason, when the shoji 12 is equal to or higher than the predetermined speed, the protrusion 26d protrudes and the movement is restricted, and when it is lower than the predetermined speed, it is possible to provide the fitting 1 that is not restricted.

  Further, since the end portion 27e of the peripheral wall portion 27c as a rotation stop portion for stopping the rotation of the peripheral surface facing member 26 is provided, the rotation of the rotated peripheral surface facing member 26 is stopped by the end portion 27e of the peripheral wall portion 27c. Thus, the rotation of the peripheral surface facing member 26 can be stopped at the position where the protruding portion 26d is protruded.

  Further, the projecting portion 26d that protrudes toward the frame body 10 from the upper collar 12c of the shoji 12 contacts the stopper 52 before the shoji 12 closes the opening. Therefore, before the opening is completely closed by the shoji 12. The shoji 12 can be stopped.

  Moreover, since the protrusion part 26d is pinched | interposed into the edge part 27e of the surrounding wall part 27c, and the stopper 52, the movement of the shoji 12 is controlled, Therefore It is possible to control the movement of the shoji 12 reliably.

  Then, when the rotation of the peripheral surface facing member 26 is stopped, the rotation of the roller 22 and the inertial body 25 integrated with the outer diameter being increased is also stopped or the rotation speed is lowered. At this time, since the centrifugal force acting on the inertial body 25 is reduced, the outer diameter of the inertial body 25 is reduced, and the inertial body 25 is separated from the circumferential surface opposing member 26, so that the circumferential surface opposing member 26 protrudes. The force that moves the portion 26d toward the frame body 10 from the upper collar 12c does not act. For this reason, when it has the leaf | plate spring 29 which urges | projects the protrusion part 26d which protruded inside the shoji 12 like the said fitting 1, when the speed of the shoji 12 becomes slower than predetermined speed, it will be promptly. The protrusion 26d can be moved to the shoji 12 side.

  Further, when the outer peripheral surface 25c of the inertial body 25 is separated from the inner peripheral surface 26a of the peripheral surface facing member 26, the protruding portion 26d is moved to the shoji 12 side, so that the outer peripheral surface 25c of the inertial body 25 is the peripheral surface. When moving away from the inner peripheral surface 26a of the opposing member 26, that is, when the speed of the shoji 12 is lower than the predetermined speed, the projecting portion 26d is moved to the shoji 12 side by the leaf spring 29, so that the projecting portion 26d is stopped by the stopper 52. The shoji 12 does not stop.

  In the above embodiment, the example in which the stopper 52 is fixed to the upper frame 10b has been described. However, as illustrated in FIG. A stopper 52 may be provided via a compression spring 30 as a cushioning material that suppresses an impact when the protruding portion 26d comes into contact. In this case, even if the shoji 12 moves at a predetermined speed or more and the protruding portion 26d comes into contact with the stopper 52, the impact can be suppressed. The buffer material is not limited to a compression spring, and may be an elastic member such as rubber.

  In the above embodiment, the member that urges the three parts constituting the annular body 25b of the inertial body 25 toward the shaft portion 25a is a coil spring. However, an annular rubber or the like may be used.

  Moreover, in the said embodiment, although the shoji 12 stopped when the shoji 12 moved at a predetermined speed or more, the door toe 12a of the shoji 12 was a position away from the vertical frame 10a by 75 mm. This is not a limitation.

  In the above-described embodiment, the example in which the roller 22 is provided on the relay shaft 24 different from the inertial body 25 has been described. However, the roller 22 may be provided on a shaft integrated with the shaft portion 25a of the inertial body 25.
