Description

The present invention relates to a suspension door device for guiding a lower portion of a suspension door and a member for constituting a running groove of the suspension door device .

Conventionally, a suspension door is suspended on the upper rail via a runner so that it can run freely, and a single guide pin provided on the floor surface so as to protrude and retract by magnetic force is formed in the running groove formed on the lower end surface of the suspension door. There is known a guide for a hanging door that is inserted in the protruding state and performs a traveling guide. (For example, see Patent Document 1, Patent Document 2, Patent Document 3, and Patent Document 4)
In the above-described conventional example, for example, as shown in FIG. 20 (FIG. 20 shows the guide for the suspension door in Patent Document 3), the upper end from the guide tool body 7 embedded under the floor 4 Since one guide pin 5 provided with a magnet 8 is protruded upward by magnetic attraction, in order to ensure the vertical movement length of the guide pin 5, one guide pin 5 is placed on the floor surface. A certain depth (indicated by dimension H in FIG. 20) below the floor surface 4 is required to immerse below.

  By the way, in recent years, direct-attached floors in which floor materials are directly attached onto floor slabs have become widespread, but in the case of such direct-attached floors, a depth sufficient to immerse the guide pins below the floor surface is secured. Therefore, the above-described conventional suspension door guide tool cannot be used on a directly pasted floor.

  Therefore, in the course of reaching the present invention, the inventor has a first guide 9 having a guide pin 5 as shown in FIG. 6 provided with a magnet 8 at the tip thereof and a cylindrical shape in which the first guide 9 is fitted so as to protrude upward. And the second guide 10 is housed in the guide tool body 7 so as to be able to protrude upward, and a locking portion 11 is provided at the lower end portion of the first guide, and the upper end of the second guide 10 is provided. The locking portion 11 is provided to the locking portion 11 so that the locking portion 11 can be freely locked. When the first guide 9 is pulled upward by a magnetic attractive force, the locking portion 11 is locked to the locked portion 12. Thus, it is considered that the second guide 10 is lifted upward by following the first guide 9. In this case, the immersion depth of the guide pin 5 to be immersed under the floor surface may be shallow, and even a directly attached floor can be dealt with.

However, in the case where the guide pin 5 is constituted by the second guide 10 having a large diameter and the first guide 10 having a small diameter in this way, the groove width of the running groove provided on the lower surface portion of the suspension door is large ( When the second guide 10 is wide, when only the first guide 1 is in the running groove, there is a problem that the groove width is too wide and the swinging of the hanging door is large. When the groove width of the running groove provided on the lower surface portion of the door is matched with the first guide 9 having a small diameter (narrow width), there is a problem that the vehicle cannot run when the second guide 10 is fitted in the running groove. That is, normally, the first guide 9 enters the traveling groove by magnetic attraction, and the second guide 10 is positioned below the traveling groove by natural fall due to its own weight. If dust or the like is collected in the slide portion with the guide 9, the second guide 10 is not fully extended from the second guide 10 when the first guide 9 enters the running groove by magnetic attraction. It has been found that there is a possibility that the upper part of the guide 10 may also be fitted in the running groove, thereby making it impossible to run.

The base frame 67 is fitted in a state in which the end portion in the longitudinal direction of the lower opening 66 is left slightly (that is, the portion into which the end block portion 48 is fitted is left).

  The attachment of the end member 44 and the intermediate member 45 to the lower end surface portion of the hanging door 1 is performed as follows.

  First, the end block portion 48 of the end member 44 is fitted into the end portion in the longitudinal direction of the lower opening 66 of the horizontal bar 59 located below, and the fitting protrusion 53 and the locking protrusion on the upper surface of the lower end face plate portion 49 are fitted. 55 is fitted into the lower end of the vertical rod 52, and at the same time, the locking portion 54 of the locking protrusion 55 is locked and attached to the opening hole 64 provided in the intermediate vertical partition 63 of the vertical rod 52. In this case, the protrusion 46 protruding from the end block portion 48 is brought into contact with the lower surface of the hooking protrusion 69 of the base frame 67. In this way, when the end members 44 are respectively attached to both ends in the longitudinal direction of the lower end surface portion of the suspension door 1, the end portions in the longitudinal direction of the lower end surface portion of the suspension door 1 are covered by the lower end surface plate portion 49 and introduced. The groove portion 41 is disposed at a position slightly drawn inward from the end portion in the longitudinal direction of the lower end surface portion of the suspension door 1, and the introduction groove portion 41 is laterally located at the end portion in the longitudinal direction of the suspension door 1. It is open and not exposed, improving the appearance.

  After attaching the end member 44 to the both lower end surface portions in the longitudinal direction of the suspension door 1 as described above, the intermediate member 45 is fitted from below into the base frame 67 having a U-shaped cross section of the horizontal fence 59 and hooked. The claw portion 58 is attached to the upper surface of the hooking projection 69 of the base frame 67 and the lower protrusion 56 is attached to the lower end surface of the base frame 67 having a U-shaped cross section. In this case, by inserting the intermediate member 45 into the base frame 67 from below, the protrusion 46 of the end member 44 is pressed upward by the receiving portion 47 of the intermediate member 45 to receive the receiving portion 47 and the hooking protrusion 69. The guide groove portion 42 and the intermediate groove portion 43 are aligned and communicated with each other as being fitted between the two.

  Thus, the suspension door 1 suspended from the upper rail 2 via the runner 3 is caused to travel, and the pole on the lower surface of the attracting magnet 15 at the end of the running groove 6 at the lower end surface portion of the suspension door 1 (S pole in the embodiment). ) Comes to a position facing the guide pin 5 that is retracted below the floor surface 4 (that is, a position inside the inclined guide 16 of the introduction groove portion 41 having a wide groove width) and the pole on the lower surface of the attracting magnet 15 and the guide. Since the pole on the upper surface of the magnet 8 provided at the upper end of the first guide 9 of the pin 5 is different in polarity, the first guide 9 is pulled upward by the magnetic force, and the first guide 9 is pulled upward, When the locking part 11 rises in the guide groove 33 and the locking part 11 hits the locked part 12, the second guide 10 is pulled up and protrudes upward by being driven by the first guide 9. The guide pin 5 extends and the introduction groove 41 at the end of the running groove 6 is obtained. Enter into. Thus, the guide pin 5 extends and is pulled upward. When the suspension door 1 is further moved in this state, the first guide 9 enters the intermediate groove portion 43 while being guided by the guide groove portion 42 while the magnet 8 is attracted by the suction magnet 15 and pulled upward. In the portion 43, the magnet 8 is attracted to the magnetic body 15a and protrudes upward to be held in an extended state. The suspension groove 1 is guided by the extended guide pin 5 while the traveling groove 6 in the lower end surface portion of the suspension door 1 is guided. It will move, and it will prevent that the lower end part of the hanging door 1 shakes. FIG. 3 shows a state in which the guide pin 5 protrudes upward and enters the running groove 6 on the lower end surface portion of the hanging door 1 to guide the running of the hanging door 1 while keeping the steady state.

  The pole on the lower surface of the attracting magnet 15 provided at the other end of the traveling groove 6 of the hanging door 1 by running the suspension door 1 while guiding the guide pin 5 into the running groove 6 as described above (implementation) In the form, when the S pole) passes through the magnet 8 of the guide pin 5 and the attraction force is lost, the guide pin 5 moves downward due to its own weight, and further, the first guide 9 moves downward to cause the second. The guide 10 also moves downward, and the first guide 9 is immersed in the second guide 10 and the second guide 10 is immersed in the inner cylinder 20 of the guide tool body 7 as shown in FIG. The guide pin 5 is located under the floor surface 4 in a contracted state. In this case, if the inclined guide 16 is provided at the end of the introduction groove 41 opposite to the guide groove 42 so as to increase toward the guide groove 42, the inclined guide 16 causes the magnet 8 of the first guide 9. The first guide 9 is pushed down against the suction of the suction magnet 15 and the first guide 9 is moved downward while reducing the suction force between the magnet 8 and the suction magnet 15 to reduce the suction force. The first guide 9 can be smoothly dropped by its own weight in an unaffected area.

  In the present invention, the guide pin 5 is configured to extend in the upward projecting state and contract in the accommodated state in the guide tool body 7 as described above. While securing a sufficient protruding distance, the depth required for storing the guide pin 5 under the floor surface 4 can be reduced (the vertical length is shortened) with the guide pin 5 immersed under the floor surface 4. Therefore, even in the case of a floor where the vertical length from the floor surface 4 to the floor slab is short such as a directly pasted floor in which the floor material is directly pasted on the floor slab, the guide for the suspension door of the present invention is used for the floor. It can be used under the surface 4. In other words, in the present invention, the vertical length of the guide tool body 7 can be made shorter than the protruding length of the guide pin 5 in the extended state, and the guide tool body 7 can be moved even if the depth of the hole 18 formed in the floor surface 4 is shallow. The guide pin 5 can be embedded and attached under the floor surface 4 and can be accommodated in the inner cylinder 20 of the guide tool body 7 in a contracted state, so that the guide pin 5 does not protrude on the floor surface 4. When the floor surface 4 is walked, the guide pin 5 can walk without getting in the way.

  The groove width of the introduction groove portion 41 is wider than that of the second guide 10, the groove width of the intermediate groove portion 43 is narrower than that of the second guide 10 and wider than that of the first guide 9, and the groove width of the guide groove portion 42 is introduced. Since it is wider than the second guide 10 at the end portion on the groove 41 side and narrower than the second guide 10 at the end portion on the intermediate groove portion 43 side and gradually wider than the first guide 9, Since the introduction groove 41 at the end in the longitudinal direction of the running groove 6 is wider than the second guide 10, the first guide 9 having a narrow width (that is, a small diameter) can be reliably introduced into the introduction groove 41 by magnetic force. In addition, after being introduced, the first guide 9 is introduced into the intermediate groove portion 43 having a narrow groove width after being guided by the guide groove portion 42 so that rattling of the sliding door 1 during traveling can be prevented. It has become.

  Here, the gap dimension between the floor surface 4 and the lower surface of the sliding door 1 is slightly different from site to site due to construction errors or the like. With some allowance, the magnet 8 at the upper end of the guide pin 5 can be surely attracted to the attracting magnet 15 in the extended state.

  In the present invention, when dust or the like is clogged in the sliding portion between the second guide 10 and the first guide 9, the first guide 9 is moved into the introduction groove 41 by attraction by magnetic force. Although the upper part of the second guide 10 may also enter the introduction groove 41 in a state in which the two guides 10 are not fully extended, in the present invention, the first guide 9 and the second guide are in the introduction groove 41. 10, the width of the guide groove 42 is wider than the second guide 10 at the end of the introduction groove 41 and narrower than the second guide 10 at the end of the intermediate groove 43 as described above. In addition, the width-adjusting portion A is configured so as to be wider than the first guide 9, and the entire width of the guide groove portion 42 or a part of the middle of the guide groove portion 42 is further lowered under the above-mentioned width condition. To make it wider Since the lowering portion B is configured, the groove width of each portion of the guide groove portion 42 is wider than that of the first guide 9 in the guide groove portion 42, so that the magnet 8 is attracted by the suction magnet 15 and the first guide 9 is However, the second guide 10 is aligned with the center of the guide groove portion 42 in the width direction so that the center of the second guide 10 is aligned with the center of the guide groove portion 42 by the width adjusting portion A. The second guide 10 is pushed downward by the push-down portion B while being pushed out from the guide groove portion 42. Thus, even if the upper portion of the second guide 10 enters the introduction groove 41 in a state where the first guide 9 is not sufficiently extended from the second guide 10, the upper guide and suction of the first guide 9 by the magnetic force are performed. The first guide 9 is introduced into the introduction groove 41 with respect to the second guide 10 whose width is shifted to the center side in the width direction of the introduction groove 41 by the downward movement of the second guide 10 by the groove 42. The first guide 9 is inserted into the guide groove 42 from the guide groove 42 to the intermediate groove 43, and the suspension door 1 is stabilized without rattling. Can be run.

  As described above, even if the upper portion of the second guide 10 enters the introduction groove 41 while the first guide 9 is not fully extended from the second guide 10, the first guide 9 is attracted upward by the magnetic force. As a result of the downward movement of the second guide 10 by the guide groove portion 42, the first guide 9 can be lifted upward with respect to the second guide 10 and a stable traveling guide of the suspension door 1 can be performed. .
