Description

  The present invention relates to an improvement in an arbitrary position stopping device for a sliding door that holds a self-closing type sliding door at an arbitrary opening position in a predetermined section including full opening and releases the holding in the event of a fire.

  In general, sliding doors are automatically opened from the open state, for example, by tilting the rail for hanging the sliding door to the closing side, or by biasing the sliding door to the closing side by using a stored energy such as a helical spring. May be configured to be closed automatically. On the other hand, there may be a configuration in which the self-closing sliding door is held at an arbitrary open position. Since the arbitrary position stop device normally holds the sliding door at an arbitrary opening position, the sliding door stops at the opening position. In the event of a fire, the signal from the fire detector is received and the holding is released, so the sliding door is self-closed and fully closed.

  Examples of such an arbitrary position stopping device include those described in the following known documents 1 and 2. This arbitrary position stopping device is attached to the sliding door and moves to the left and right together with the opening and closing operation of the sliding door. Normally, the sliding door is stopped by pressing the rail, or the roller traveling on the rail is pressed. To stop the sliding door. In the event of a fire, a signal from the fire detector is received to release the rail or roller from being pressed by a solenoid or the like.

  However, since a drive mechanism such as a solenoid is attached to the sliding door side and moves to the left and right according to the opening / closing operation of the sliding door, wiring processing for supplying power becomes a problem, and when receiving a signal from a fire detector Wiring processing for signal reception also becomes a problem. On the other hand, it can be driven by batteries, but it is not suitable for practical use because it is not suitable for long-term use, and wireless reception is also possible, but in the event of a fire, there is a lack of certainty of reception because it is an emergency. There's a problem. In any case, in reality, wiring for power supply and reception is performed from the wall side, which causes a problem that wiring processing is difficult.

In order to solve the problem of such wiring processing, the following Patent Documents 3 and 4 have a configuration in which a part for driving a movable member for holding and releasing and a part for receiving from a fire detector are attached to the wall side instead of the sliding door side. Proposed.

  However, since the length of the movable member is short, there is a problem that the section where the sliding door can be held is short. If it is attempted to lengthen the section, the movable member also becomes long, and the drive becomes large and causes a failure.

  Then, this invention makes it a subject to provide the arbitrary position stop apparatus of a sliding door which can hold | maintain a sliding door over a wide area by simple structure with easy wiring processing for a drive, reception, etc. .

  The present invention has been made to solve the above problems, and the arbitrary position stopping device for a sliding door according to the present invention holds a self-closing type sliding door at an arbitrary open position in a predetermined section including a fully open state and at the time of a fire or the like. In a sliding door arbitrary position stop device that receives a signal from the outside in the event of an emergency and releases the holding of the sliding door, the sliding door includes a held member that is attached to the sliding door side, and a device body that is attached to the wall side. The main body of the apparatus holds the elongated portion at an arbitrary position in the longitudinal direction and receives a signal from the outside in an emergency to hold the elongated portion. It is characterized by releasing.

  In the arbitrary position stopping device for the sliding door having the above structure, the device body that holds the long portion and receives the signal from the outside and releases the holding of the long portion is not a sliding door side but a wall such as a door frame. Since the structure is attached to the side, wiring for power supply required for holding and releasing the elongated portion and wiring for receiving signals from the outside are arranged on the wall side. . And since it is the structure which attaches the to-be-held member which has a long shape part to the sliding door side, and hold | maintains the arbitrary positions of the longitudinal direction, while the member for holding a to-be-held member can be small, long shape Since it is not necessary to drive a held member having a portion, it can be easily stopped in a long section. In addition, the apparatus main body can be disposed near the end of the sliding door when the sliding door is fully closed, and can be applied to specifications in which the sliding door is housed in a wall.

  In particular, it is preferable that the holding force of the sliding door is configured to be adjustable. There are various configurations for holding the member to be held, such as by pressing and by magnetic force, but in any case, the holding force can be adjusted so that the holding force can be adjusted appropriately according to the conditions of the installation location. Can be stopped reliably.

  In addition, the apparatus main body includes a holding member that holds the long portion by pressing it in the vertical direction, and the holding member moves in a direction away from the long portion in an emergency. It is preferable that the holding force can be adjusted on the held member side by configuring the position to be adjustable. In the case of a configuration in which the holding portion releases and holds the long portion by pressing and holding the long portion in the vertical direction, the holding force can be adjusted by adjusting the vertical position of the long portion. Can be easily adjusted on the held member side. In an emergency, the holding member may not be completely separated from the long portion. Further, in addition to what can adjust the vertical position of the held member itself, only the elongated portion of the held member may be configured to be able to adjust its vertical position.

  In particular, by configuring the mounting position of the held member with respect to the sliding door so as to be adjustable in the vertical direction, the vertical position of the elongated portion can be adjusted with a simple configuration, and when mounting the held member to the sliding door The holding force can be adjusted easily.

  Further, the apparatus main body includes a holding member that holds the long portion by pressing it in the vertical direction, and the holding member moves in a direction away from the long portion in an emergency, and the vertical position of the holding member is It is preferable that the holding force can be adjusted on the apparatus main body side by being configured to be adjustable. Although the holding force can be adjusted on the held member side as described above, the holding force can be easily adjusted on the apparatus main body side by configuring the holding member so that the vertical position of the holding member can be adjusted. In this case, the entire apparatus main body may be configured to be vertically adjustable, or only the holding member may be adjustable.

  In particular, if the mounting position of the apparatus main body is configured to be adjustable in the vertical direction, the vertical position of the holding member can be adjusted with a simple configuration, and the holding force can be easily applied when mounting the apparatus main body to the sliding door. Can be adjusted to.

  The apparatus main body includes a holding member that holds the long portion by pressing it in the vertical direction. The holding member moves in a direction away from the long portion in an emergency, and the holding member is fully closed. In some cases, it is preferable that the long portion is not pressed. Since the holding member does not press the long portion when fully closed, the force at the start of opening can be small.

  Further, the apparatus main body includes a holding member that holds the long portion by pressing in the vertical direction, and the holding member moves in a direction away from the long portion in an emergency, and when the sliding door is fully opened. It is preferable that the portion pressed by the holding member of the elongated portion is supported by the support portion from the side opposite to the pressing side. When the sliding door is fully opened, it is the most frequently stopped part, but when the sliding door is fully opened, the elongated part is supported by the support part, so that it is not easily deformed even if pressed by the holding member. It can be reliably held in its fully open position.

  In addition, the wall is provided with a cover panel that detachably covers the predetermined upper area of the opening that opens by the opening operation of the sliding door, so that the upper predetermined area is detachable. It is preferable to express by. Since the attachment part for attaching the device main body to the wall side is revealed by removing the lid panel, it can be easily repaired or replaced by removing the device main body through the upper predetermined area that became the inspection port. Especially, it is suitable for the so-called wall storage specification in which the sliding door is stored in the wall.

  Furthermore, it is preferable that the attachment part of the apparatus main body is provided at a position eccentric to the door end side of the apparatus main body, and the attachment part of the apparatus main body can be easily exposed without exposing the entire apparatus main body. it can.

  As described above, the sliding door arbitrary position stopping device according to the present invention has a configuration in which the apparatus main body is attached to the wall side, so that it is easy to process the wiring for power supply and signal reception from the outside, and on the sliding door side. Since it is set as the structure which attaches the to-be-held member which has an elongate part, the structure for holding a to-be-held member can be simplified, and a sliding door can be hold | maintained over a wide area.

DESCRIPTION OF EMBODIMENTS Hereinafter, an embodiment of a sliding door arbitrary position stopping device according to the present invention will be described with reference to FIGS.
The arbitrary position stopping device for the sliding door in the present embodiment is applied to a so-called self-closing type sliding door 4 configured to automatically close from an open state as shown in FIG. 1, for example. FIG. FIG. 2 shows a case where the sliding door 4 is held in the fully open position in a normal state, and FIG. 3 shows a state at the moment when the holding of the sliding door 4 is released in a fire. Here, 1 is a vertical frame on the door end side, 2 is a vertical frame on the door bottom side, 3 is an upper frame that connects the upper ends of both vertical frames 1 and 2 in the horizontal direction, 2 and the upper frame 3 constitute a door frame. A rail 5 for hanging the sliding door 4 is attached to the upper frame 3, and the sliding door 4 is opened and closed by sliding on the rail 5 when the door wheel 6 attached to the upper end of the sliding door 4 runs on the rail 5. In addition, the door cart 6 is attached to the two places of the door end side and the door bottom side of the sliding door 4 through the door support member 7 (refer FIG. 4), respectively.

  The sliding door 4 is configured to be automatically closed by a self-closing force accumulating device 11 that urges the sliding door 4 to the closed side using an accumulating force such as a helical spring. The self-closing force accumulating device 11 is attached to the door end side of the upper frame 3 and a wire 12 for energizing the helical spring is connected to the sliding door 4. 12 is pulled out to the right side in the figure, and accordingly, the helical spring accumulates energy, and the accumulated force is transmitted to the sliding door 4 through the wire 12 to urge the sliding door 4 to the closing side. In addition, it is good also as a structure which urges | biass the sliding door 4 to the closing side with the dead weight by making the rail 5 incline below toward the door end side.

  Furthermore, a brake device 8 having a pinion gear (not shown) is attached to the doorside support member 7 on the door end side, and the pinion gear of the brake device 8 is placed on the door tip side of the rail 5 before the sliding door 4 is fully closed. By engaging with the rack 9 provided, the sliding door 4 is decelerated, so that the sliding door 4 does not vigorously fully close. In addition, the door stopper 10 is attached to the vertical frame 2 on the door bottom side in order to reduce the collision of the sliding door 4 when fully opened.

  And in such a self-closing type sliding door 4, the sliding door 4 is held at an arbitrary opening position in a predetermined section including full opening, and at the time of a fire, a signal from a fire detector is received to release the holding of the sliding door 4. A stop device is used. Specifically, the arbitrary position stopping device includes a holding rail 20 as a held member attached to the sliding door 4 and a device main body 30 attached to the upper frame 3. The holding rail 20 has a long portion extending along the opening / closing direction of the sliding door 4. In this embodiment, the holding rail 20 is a single rod-like body, specifically a square bar, and the whole is long. It is comprised as a shape part. More specifically, it is located above the door pulley 6 so as to bridge between the two door wheels 6, and is attached to each door wheel support member 7 via the attachment member 21 as shown in FIG.

  The attachment member 21 is a plate-like member that is bent in an inverted L shape, and a pair of upper and lower long holes 22 that are long in the vertical direction are provided in the vertical plate portion 21a. And is attached to the door support member 7 so that the position can be adjusted in the vertical direction. Then, the holding rail 20 is attached to the top plate portion 21b of the attachment member 21 by screws. The holding rail 20 is attached by screwing a screw from below the top plate portion 21b. Therefore, the mounting position of the holding rail 20 can be adjusted in the vertical direction by attaching the mounting member 21 to the door support member 7 so that the position of the holding rail 20 can be adjusted in the vertical direction by the long hole 22. The height of the upper surface 20a can be adjusted. The attachment member 21 is similarly formed with a long hole 22 on both the door end side and the door end side, and the height of the holding rail 20 can be adjusted at two locations on the door end side and the door end side. ing. FIG. 4 shows the case where the holding rail 20 is adjusted to the lowest position. When the holding rail 20 is moved away from the holding member 31 in the vertical direction, the pressing force (holding force) can be adjusted in the decreasing direction.

  Thus, the holding rail 20 attached to the sliding door 4 via the attachment member 21 is attached so that the upper surface 20a is flat and the flat upper surface 20a is substantially horizontal as shown in FIG. The door butt side end portion 20b is set so as not to protrude from the door butt side end portion 4a of the sliding door 4 while extending a predetermined length further from the door butt side attachment member 21 to the door butt side. Yes.

  On the other hand, the apparatus main body 30 includes a holding member 31 that holds the holding rail 20 at an arbitrary position in the longitudinal direction thereof, and a holding rail that is held by the holding member 31 in response to a signal from a fire detector such as a smoke detector (not shown) in the event of a fire. And a release mechanism for releasing the holding of 20. As shown in FIG. 6, the apparatus main body 30 includes a plate-like base 32 for attaching to the upper frame 3. On the door side of the base 32, a pair of left and right long slots 33 for attachment that are long in the vertical direction are provided as attachment parts to the upper frame 3. A movable arm 34 is attached to the base 32 so as to be pivotable up and down with the door end side end as a fulcrum.

  The movable arm 34 is in a substantially horizontal state in a normal state shown in FIG. 6, but is always urged upward by a tension spring 35 as urging means, while its upward movement is caused by a hook member 36 described later. It is blocked. The holding member 31 is attached to the door butt side end of the movable arm 34. The holding member 31 is rotatably attached to the movable arm 34 so as to rotate along the rotation surface of the movable arm 34. The holding member 31 is made of, for example, rubber having elasticity, and the tip portion 31a is formed in an outer convex arc shape. A large number of irregularities are formed on the arcuate surface of the tip 31 a of the holding member 31. Further, the holding member 31 is formed in a long hole shape with respect to the movable arm 34 and is movable relative to the movable arm 34. The holding member 31 is normally provided with a spring 37 as a built-in biasing means. 31a is urged away from the center of rotation. In the free state, the holding member 31 hangs downward from the rotation center so that the tip 31a faces downward due to its own weight.

  The state where the movable arm 34 as shown in FIG. 6 is substantially horizontal is a normal state, and in the event of a fire, the movable arm 34 as shown in FIG. A mechanism for moving the holding member 31 upward by a predetermined amount by retracting the movable arm 34 in this manner is the release mechanism, which will be described. When the solenoid 39 receives a signal from the fire detector via the wiring 38, the solenoid 39 retracts the mandrel 40 upward from the state of FIG. 6 to the state of FIG. The end of the mandrel 40 of the solenoid 39 is prevented from further advancing with the cap nut 41 attached to the movable arm 34 as the contact surface. Then, when the solenoid 39 retracts the mandrel 40 upward, the hook pin 42 protruding in the radial direction at the tip of the mandrel 40 is one of the two link arms 43 and 44 constituting the toggle mechanism. The link arm 43 is pushed upward from the lower side. Here, the two link arms 43 and 44 constituting the toggle mechanism are urged downward by a torsion spring 45 so that one of the two link arms 43 and 44 does not protrude downward from the substantially horizontal state as shown in FIG. The link arm 43 is in contact with a screw 46 as a contact surface. When the solenoid 39 is activated and the mandrel 40 is retracted upward in the event of a fire, the two link arms 43 and 44 are formed in an upward convex shape as shown in FIG. 7 and are pivotally attached to the other link arm 44. The lever 47 rotates like a pendulum on the left side in the drawing with the upper end portion as a fulcrum. When the lever 47 is rotated clockwise, the hook member 36 locked to the lever 47 is rotated counterclockwise by the urging force of the tension spring 48. The hook member 36 is provided with a roller 49 as a restricting member, and normally the movable arm 34 is pushed downward to prevent its upward rotation. Further, a pin 52 of a slider 51 urged to the right side by a tension spring 50 is engaged with the notch portion of the hook member 36. Accordingly, when the hook member 36 is rotated counterclockwise, the roller 49 pressing the movable arm 34 is moved upward, whereby the movable arm 34 is rotated upward by the tension spring 35 and the slider. The pin 51 of 51 is removed from the notch portion of the hook member 36, and the slider 51 is moved to the right side by the tension spring 50. A pin 53 protrudes upward from the slider 51, and a wire 54 is connected to the pin 53. Therefore, when the wire 39 is pulled to the left after the solenoid 39 is actuated in a fire and the state shown in FIG. 7 is reached, the slider 51 moves to the left against the urging force of the tension spring 50, and the holding member 31 and the like return to the original state shown in FIG.

  The apparatus main body 30 configured as described above is attached to the upper frame 3 as shown in FIG. 1, and its vertical attachment position can be adjusted by the elongated hole 33 of the base 32, for example, The vertical position of the holding member 31 can be adjusted by setting it to the highest position as shown in FIG. The mounting position of the apparatus main body 30 is, for example, approximately the center in the left-right direction of the upper frame 3 (the opening / closing direction of the sliding door 4). In the fully closed state shown in FIG. 1, the holding rail 20 attached to the sliding door 4 and the holding member 31 of the apparatus main body 30 are separated from each other in the left-right direction, and therefore the holding member 31 contacts the holding rail 20. Without holding it pressed.

  Here, the attachment position to the upper frame 3 of the apparatus main body 30 will be further described. The arbitrary position stopping device for the sliding door in the present embodiment is a so-called wall storage in which a part of the wall 100 as shown in FIG. 8 is formed as a door pocket 101 and the opened sliding door 4 is stored in the door pocket 101 of the wall 100. It is suitable for the specification. 101a in the figure is an opening edge of the door pocket 101 of the wall 100. Above the opening 102 opened by the opening operation of the sliding door 4, there is a horizontally long rectangular region (predetermined upper region) in front view. Covered with a lid panel 103. The lid panel 103 is detachably attached, and when the lid panel 103 is detached, the region is used as an inspection port. That is, when the lid panel 103 is opened, the two door wheels 6 of the sliding door 4 and the attachment member 21 of the holding rail 20 when fully closed are also exposed. Therefore, it is possible to easily adjust the height of the holding rail 20 or to exchange it. Further, the door butt side end portion 103a of the lid panel 103 is flush with the opening edge portion 101a of the door pocket 101 of the wall 100, and the device main body 30 extends across the door butt side end portion 103a of the cover panel 103 from side to side. Is attached to the upper frame 3. In other words, the apparatus main body 30 can be positioned near the door bottom side of the sliding door 4 when fully closed. When the cover panel 103 is removed, a predetermined area on the door end side of the device main body 30 is also exposed, and the attachment long hole 33 as the attachment portion of the device main body 30 is eccentrically positioned on the door bottom side. By operating the screw 60 screwed into the long hole 33 for use, for example, the apparatus main body 30 can be removed and adjusted, replaced, or the mounting position thereof can be adjusted to adjust the holding member 31 in the vertical direction. The position can be adjusted, and as a result, the holding force can be easily adjusted. Note that the door butt side end 20b of the holding rail 20 is slightly located on the door butt side of the door butt side end 103a of the lid panel 103, and the holding member 31 is also on the door butt side of the cover panel 103, that is, the door pocket. 101. Therefore, it is preferable to provide the attachment long hole 33 as the attachment portion of the apparatus main body 30 only at a position eccentric from the center in the left-right direction of the apparatus main body 30 to the door end side. It is preferably located on the side. By removing the lid panel 103 in this way, both the holding rail 20 and the apparatus main body 30 can be inspected. The power supply to the apparatus main body 30 and the signal reception from the fire detector are performed via the wiring 38. However, since the wiring 38 is also exposed, the inspection can be easily performed. 30 is preferably arranged only at a position eccentric from the center in the left-right direction to the door end side, whereby the wiring 38 can be easily inspected from the inspection port.

  Then, when the sliding door 4 is slightly opened from the state of FIG. 1, the holding member 31 comes into contact with the upper surface 20a of the holding rail 20, and the holding member 31 is rotated to the right side, that is, the door bottom side with the center of rotation as a result of the frictional resistance. Move. If the hand that operates the sliding door 4 is released at that position, the sliding door 4 tends to be closed by the stored force of the helical spring, but the holding member 31 is turned to the upper surface 20a of the holding rail 20 in a state where the holding member 31 is rotated to the door bottom side. Because of the contact, the holding member 31 holds the holding rail 20 in that position. Therefore, the sliding door 4 is held in its open position. However, when a person applies a force toward the closing side to the sliding door 4, the holding member 31 is elastically deformed by the elasticity held by the holding member 31 and the built-in spring 37 is compressed, so that the holding member 31 rotates to the door end side. The sliding door 4 can be closed. The opening position can be held at any position as long as the holding member 31 is in contact with the holding rail 20. Therefore, the sliding door 4 can be stopped at an arbitrary position in the longitudinal direction of the holding rail 20, and in the present embodiment, the entire holding rail 20 is a long portion, so that the entire length can be stopped. Of course, as shown in FIG. 2, the sliding door 4 can be held in the fully open position. Although this fully open state is considered to be the most frequently used, the holding member 31 is positioned above the attachment member 21 on the door-end side when fully opened. Therefore, the portion of the holding rail 20 that is pressed downward by the holding member 31 is supported from the lower side with the attachment member 21 on the door end side as a support portion, and the pressing force that the holding rail 20 receives from the holding member 31 Is prevented from bending downward, and is reliably held in the fully open state, which is its open position.

  If a fire occurs, the fire detector detects it and sends a signal to the apparatus main body 30. The apparatus main body 30 operates the solenoid 39 accordingly to rotate the movable arm 34 upward to hold the holding member. 31 is moved upward. Due to the upward movement of the holding member 31, the holding member 31 is separated upward from the upper surface 20 a of the holding rail 20, and the state in which the holding member 31 presses the holding rail 20 downward is released, that is, by the holding member 31. The holding of the holding rail 20 is released. Therefore, the sliding door 4 automatically moves to the closing side and becomes fully closed. As described above, the state is maintained until the wire 54 is pulled, and the original state is restored by the operation of the wire 54.

  In the arbitrary position stopping device for the sliding door 4 configured as described above, the device main body 30 that receives the signal from the fire detector and operates the holding member 31 is attached to the upper frame 3 instead of the sliding door 4 side. The processing of the wiring 38 is easy. And since it is the structure hold | maintained by the holding member 31 which attaches the elongate holding rail 20 to the sliding door 4, and presses it from upper direction, while being able to make the holding member 31 small, holding | maintenance and its cancellation | release The sliding door 4 can be held at an arbitrary position in a long section without making the configuration of FIG. Moreover, since the apparatus main body 30 can be arrange | positioned in the approximate center of the upper frame 3, it can test | inspect easily by removing the cover panel 103. FIG. In particular, since the mounting elongated hole 33 as the mounting portion is exposed, the repair and replacement are easy, and the vertical position of the holding member 31 is adjusted by adjusting the height, and the pressing force to the holding rail 20 is adjusted. That is, the holding force can be adjusted. Since the holding rail 20 can also be adjusted in height, the holding force can be adjusted also on the holding rail 20 side. Furthermore, since the holding member 31 is not in contact with the holding rail 20 when fully closed, it is easy to start opening, and since the holding rail 20 is long, the sliding door 4 is held over a long section. it can.

  In the present embodiment, the height of both the holding rail 20 and the apparatus main body 30 can be adjusted. However, either one may be used, and the specification may not allow the height to be adjusted. Further, for example, as a configuration for adjusting the vertical position of the holding rail 20, in addition to the above-described configuration, for example, the mounting position for mounting the holding rail 20 on the mounting member 21 can be configured to be adjustable in the vertical direction. In addition to the configuration for adjusting the mounting position of the holding rail 20, the vertical position of the elongated portion may be adjusted by the configuration of the holding rail 20 itself. In addition, although the vertical positions can be adjusted by the mounting long holes 22 and 33, it is needless to say that the vertical position adjustment method is arbitrary, such as a configuration in which a plurality of mounting holes are provided at intervals in the vertical direction. Moreover, you may attach the holding rail 20 and the apparatus main body 30 by means other than a screw | thread.

  Moreover, although the case where the whole holding rail 20 was an elongate part was demonstrated, the structure which has an elongate part in the part may be sufficient, and the to-be-held member which has an elongate part at least is the sliding door 4. Any configuration may be used as long as it is attached to the. Therefore, the design of the mounting structure of the held member 31 can be changed as appropriate.

  Furthermore, although the structure which hold | maintains by pressing the holding rail 20 from upper direction was demonstrated, the direction of a press is also arbitrary. When releasing the holding, the holding member 31 may not be completely separated from the holding rail 20. Similarly, the holding member 31 may be in contact with the holding rail 20 even at the start of opening. Furthermore, the design of the configuration for releasing the holding can be changed as appropriate.

  In addition, although it is suitable for a wall storage specification, it is natural that it is suitable also for the construction specification which does not have the door pocket 101.
