Description

  The present invention relates to a guide device for a suspension door for guiding a lower portion of the suspension door, and a method for adjusting the position of a guide pin in the device.

  Conventionally, the suspension door body is suspended on the upper rail via a runner so that it can run freely, and a 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 body. Japanese Laid-Open Utility Model Publication No. 4-113670 (Patent Document 1) discloses a guide device for a hanging door that is inserted in a protruding state and performs a traveling guide. In this conventional example, as shown in FIG. 11, an outer cylinder 7 is embedded under the floor surface 4, and an inner cylinder 8 in which a guide pin 5 is accommodated so as to protrude upward is fitted into the outer cylinder 7. It is attached.

  And as shown in FIG. 1 (the figure which shows embodiment of this invention is used), the attracting magnet 10 is attached to the both ends of the running groove 6 formed in the lower end surface of the suspension door main body 1, and this attracting magnet 10 is Are arranged so that the N pole and the S pole are aligned in the longitudinal direction of the running groove 6. In this case, the same pole is located outside both the attracting magnets 10 and the same pole is located inside the both attracting magnets 10. It is like that. On the other hand, as shown in FIG. 11, a magnet 20 is provided at the upper end of the guide pin 5, and this magnet 20 is arranged such that the N pole and the S pole are arranged in the vertical direction. The upper surface side is the same as the pole located outside the attraction magnet 10. A lower magnet 21 is provided at the lower end portion of the guide pin 5, and the holding magnet 22 is magnetically attached to the lower magnet 21 at the lower end portion of the guide pin 5 in a state where the guide pin 5 protrudes upward from the wall portion of the inner cylinder 8. Is provided.

  The suspension door body 1 moves in a state of being suspended from the upper rail, and the pole located on the inner side of the N and S poles of the attracting magnet 10 provided at one end of the running groove 6 of the suspension door body 1 is a guide. When the position is opposite to the pin 5, the guide pin 5 is pulled upward because of the different polarity. Thus, when the guide pin 5 is pulled upward, the lower magnet 21 provided at the lower end of the guide pin 5 is The magnet 22 is magnetized so as to face the holding magnet 22, and the protruding state of the guide pin 5 upward is held. Therefore, when the suspension door main body 1 is moved in this state, the guide pin 5 is inserted into the traveling groove 6 and the suspension door main body 1 moves smoothly without rattling in the guided state.

  When the suspension door body 1 moves and the poles located on the outside of the N and S poles of the attracting magnet 10 provided at the other end of the traveling groove 6 are opposite to the guide pins 5, they are of the same polarity. The guide pin 5 repels and moves downward to be immersed in the inner cylinder 8. In this case, the magnetic force that repels and separates the magnet 20 at the upper end portion of the guide pin 5 and the attracting magnet 10 is held by the lower magnet 21 provided at the lower end portion of the guide pin 5 and the wall portion of the inner cylinder 8. The magnet 22 is set to be larger than the magnetic force attracted by the magnet 22, so that the pole located outside of the N and S poles of the attracting magnet 10 provided at the other end of the traveling groove 6 faces the guide pin 5. When it is in the position, the guide pin 5 is repelled and moved downward because it has the same polarity, so that it is immersed in the inner cylinder 8.

  In the conventional example as described above, only when the guide pin 5 faces the running groove 6 on the lower end surface of the suspension door body 1, it projects upward and guides the lower end portion of the suspension door body 1. In the state where the traveling groove 6 of the suspension door body 1 is separated from the guide pin 5, the guide pin 5 is immersed below the floor surface 4, and as a result, the guide pin 5 does not disturb at all during walking. It is like that.

  By the way, in the conventional example as described above, a plurality of holes are formed in the floor surface 4 at the site, and the outer cylinders 7 are fitted and attached to the plurality of holes, respectively. The inner cylinder 8 that accommodates the upper part 5 so as to be freely protruded is fitted and attached, and the plurality of guide pins 5 attached as described above are installed so as to be positioned on a straight line parallel to the upper rail. The task is difficult and cumbersome, and therefore requires skilled workers. Here, if the plurality of guide pins 5 are not positioned on a straight line parallel to the upper rail, the suspension door body 1 cannot be smoothly moved so that the lower end portion thereof does not rattle.

  Therefore, as a means for solving the problems in the conventional example as described above, there has been proposed a suspension door guide device as disclosed in JP-A-11-71954 (Patent Document 2). As shown in FIG. 1 (referring to the drawing showing the embodiment of the present invention), the suspension door main body 1 has a suspension door body 1 suspended from an upper rail through a runner so that it can run freely. The guide pin 5 provided so as to be freely projecting and retracting is inserted into the traveling groove 6 formed on the lower end surface of the suspension door body 1 in the projecting state to perform the traveling guide.

  In the guide device for the hanging door, as shown in FIG. 12A, the outer cylinder 7 is embedded under the floor surface 4, and the inner cylinder 8 is fitted into the outer cylinder 7 and the inner cylinder 8 is fitted. The insertion position in the circumferential direction can be made variable with respect to the outer cylinder 7, and a guide pin insertion hole 9 having an upper opening is formed in the inner cylinder 8, and the center of the guide pin insertion hole 9 is formed as shown in FIG. Is eccentric with respect to the center of the inner cylinder 8, and the guide pin 5 is accommodated in the eccentric guide pin insertion hole 9 so as to protrude upward.

In this case, a flange portion 14 is provided at the upper end portion of the outer cylinder 7 to determine the insertion depth of the outer cylinder 7. Further, the flange 15 of the upper end portion of the inner cylinder 8 is placed on the flange portion 14 of the outer cylinder 7 to determine the fitting depth, and the lower end portion of the inner cylinder 8 is elastically locked. The claw portion 16 is positioned slightly below the lower end portion of the outer cylinder 7 so as to prevent an unexpected disconnection upward. Therefore, in this guide device for the hanging door, the position of the guide pin 5 in a plan view can be adjusted by changing the circumferential fitting position of the inner cylinder 8 with respect to the outer cylinder 7, whereby a plurality of The guide pin 5 is positioned on a straight line parallel to the upper rail, and the suspension door body 1 can be smoothly moved so that the lower end portion thereof does not rattle.

  Further, in the suspension door guide device of this embodiment, as shown in FIG. 4, a locking claw portion 16 having elasticity is suspended from the lower end portion of the inner cylinder 8, and the locking claw portion 16 is connected to the outer cylinder 7. The inner cylinder 8 in the fitted state is prevented from being pulled up with respect to the outer cylinder 7 by being locked to the lower end portion of the outer cylinder 7. Then, as shown in FIG. 8B, the inner cylinder 8 is pulled up and the latching claw portion 16 resists its elasticity and is unlocked from the lower end portion of the outer cylinder 7. At a stage before being completely pulled out from the outer cylinder 7, a rotation space K from which the stopper means 30 is removed is formed in the outer cylinder 7 so that the locking claw portion 16 can rotate in the outer cylinder 7.

  Further, in the guide pin position adjusting method of this embodiment, as shown in FIG. 8B, in the above-described guide device for the suspension door, an operation of attracting the magnet 20 provided at the upper end portion of the guide pin 5 by its magnetic force. By bringing the tool M close to the upper end, the guide pin 5 protrudes from the guide pin insertion hole 9 of the inner cylinder 8, and the inner cylinder 8 pulled up with the guide pin 5 in the protruding state is moved to the outer cylinder. 7, the position of the guide pin 5 in a plan view is adjusted.

  The suspension door guide device and guide pin position adjusting method of this embodiment will be described in more detail below. As shown in FIG. 2, runners 3 are provided at both ends of the upper end of the suspension door body 1, and these runners 3 are fitted into an upper rail 2 attached to a ceiling or the like so as to run freely. The hanging door body 1 is suspended from the upper rail 2 so as to be able to run. As shown in FIG. 1, guide pins 5 are provided on the floor surface 4 below the upper rail 2 in parallel with the upper rail 2 so as to protrude and retract by a magnetic force at an appropriate interval.

  A running groove 6 is formed on the lower end surface of the hanging door body 1 over its entire length. As shown in FIG. 1, attracting magnets 10 are attached to both ends of the running groove 6. The attracting magnets 10 are arranged so that the N pole and the S pole are aligned in the longitudinal direction of the running groove 6. is there. In this case, the same pole is positioned outside both the attracting magnets 10 and the same pole is positioned inside both the attracting magnets 10. For example, as shown in FIG. 1, if the outside of the attracting magnet 10 attached to one side end is the N pole and the inside is the S pole, the attracting magnet 10 attached to the other side end is also the N pole outside and the inside is S. It is set to be a pole. Further, inclined guides 11 made of a magnetic material such as an iron plate are provided on both sides of the attraction magnet 10.

  Next, the structure which provides the guide pin 5 with respect to the floor surface 4 so that protrusion and retraction is possible is demonstrated. As shown in FIGS. 3 to 5, an outer cylinder 7 is embedded under the floor surface 4. The outer cylinder 7 has a biting protrusion 12 on the outer peripheral surface portion. A hole 13 is drilled in the floor surface 4 by a drill. The outer cylinder 7 is driven into the hole 13 from above, and the biting protrusion 12 is inserted into the hole 13. The outer cylinder 7 is embedded and fixed below the floor surface 4 by biting into the inner wall surface of the floor. Here, a flange portion 14 is provided at the upper end portion of the outer cylinder 7 to determine the insertion depth of the outer cylinder 7.

  The inner cylinder 8 is fitted into the outer cylinder 7 and the circumferential fitting position of the inner cylinder 8 with respect to the outer cylinder 7 is made variable. Here, the flange portion 15 at the upper end portion of the inner cylinder 8 is placed on the flange portion 14 of the outer cylinder 7 to determine the fitting depth. In this case, the elasticity of the lower end portion of the inner cylinder 8 is determined. The latching claw portion 16 that is provided is positioned slightly below the lower end portion of the outer cylinder 7 so as to prevent unintentional disconnection upward.

  A guide pin insertion hole 9 having an upper opening is formed in the inner cylinder 8, and the center of the guide pin insertion hole 9 is eccentric with respect to the center of the inner cylinder 8 as shown in FIGS. The guide pin 5 is accommodated in the guide pin insertion hole 9 so as to protrude upward. The guide pin 5 is provided with a long hole 17 which is elongated in the vertical direction, and the body portion of the inner cylinder 8 is provided with a horizontal hole 18 which is inserted into and fixed to the horizontal hole 18 of the inner cylinder 8. 19 is inserted through the long hole 17 of the guide pin 5 so that the guide pin 5 can move in the vertical direction only within a range in which the long hole 17 can slide relative to the lateral pin 19 with respect to the inner cylinder 8. It is set to.

  A magnet 20 is provided at the upper end of the guide pin 5, and the magnet 20 has an N pole and an S pole arranged in the vertical direction, and the upper surface side of the magnet 20 provided on the guide pin 5 is the attracting magnet 10. The same pole as the pole located outside. That is, for example, as described above, when the outside of the attracting magnet 10 is the N pole and the inside is the S pole, the upper surface side of the magnet 20 at the upper end of the guide pin 5 is set to the N pole. Further, a lower magnet 21 is provided at the lower end portion of the guide pin 5, and a holding magnet 22 is provided at a substantially intermediate portion in the vertical direction of the body portion of the inner cylinder 8, so that the guide pin 5 moves upward. In this state, the lower magnet 21 is magnetically attached to the holding magnet 22 so as to hold the protruding state of the guide pin 5 upward.

  As described above, the plurality of guide pins 5 are attached to the floor surface 4 so as to protrude and retract, but the plurality of guide pins 5 positioned on the traveling locus of the suspension door body 1 must be positioned in a straight line. In the guide pin position adjusting method of this embodiment, since the center of the guide pin insertion hole 9 is eccentric with respect to the center of the inner cylinder 8, the inner cylinder 8 into which the guide pin 5 is fitted is attached to the outer cylinder 7. By rotating in contrast, the position of the guide pin 5 in plan view can be adjusted to match the traveling locus of the hanging door body 1 (that is, the traveling locus of the traveling groove 6).

  Then, the suspension door body 1 suspended from the upper rail 2 via the runner 3 is caused to travel, and the pole inside the attracting magnet 10 located at the end of the travel groove 6 on the lower end surface of the suspension door body 1 (the embodiment). The S pole) reaches the position facing the guide pin 5 that is retracted below the floor surface 4, the pole inside the attracting magnet 10 and the pole on the upper surface of the magnet 20 provided at the upper end of the guide pin 5 are located. Because of the different polarity, the guide pin 5 is pulled upward by the magnetic force, and the guide pin 5 enters the running groove 6. As described above, when the guide pin 5 is pulled upward, the lower magnet 21 provided at the lower end portion of the guide pin 5 faces the holding magnet 22 provided at a substantially middle portion in the vertical direction of the body portion of the inner cylinder 8. As a result, the guide pin 5 protrudes upward and is held in the traveling groove 6 in the lower end surface portion of the hanging door body 1.

  Therefore, if the suspension door body 1 is further moved in this state, the suspension door body 1 is moved while the traveling groove 6 at the lower end surface portion of the suspension door body 1 is guided by the guide pin 5, and the suspension door body 1 is moved. The swing of the lower end portion of 1 is prevented. FIG. 1 shows a state in which the guide pin 5 protrudes upward and enters the running groove 6 on the lower end surface of the hanging door body 1 to guide the running of the hanging door body 1 while preventing the swinging.

  As described above, the guide pin 5 is inserted into the traveling groove 6 and guided while the suspension door body 1 is caused to travel to the outer pole of the attracting magnet 10 provided at the other end of the traveling groove 6 of the suspension door body 1 ( In the embodiment, when the N pole) reaches the position of the guide pin 5, the outside pole of the attracting magnet 10 and the pole on the upper surface of the magnet 20 provided at the upper end of the guide pin 5 are repulsive and repel each other. A force that pulls the guide pin 5 downward acts. In this case, the magnetic force that repels and separates the magnet 20 at the upper end portion of the guide pin 5 and the attracting magnet 10 is held by the lower magnet 21 provided at the lower end portion of the guide pin 5 and the trunk portion of the inner cylinder 8. Therefore, when the poles located outside the attracting magnet 10 provided at the other end of the running groove 6 are positioned opposite to the upper surface of the guide pin 5, Because of the same polarity, the guide pin 5 repels and moves downward to be immersed in the inner cylinder 8.

  Thus, after the sliding door main body 1 passes, the guide pin 5 is immersed in the inner cylinder 8 and retreats below the floor surface 4, so that the guide pin 5 becomes an obstacle when walking on the floor surface 4 or the like. There is nothing. By the way, in order to make the fitting position in the circumferential direction of the inner cylinder 8 variable with respect to the outer cylinder 7, as shown in FIGS. The stopper means 30 is provided so that the inner cylinder 8 is prevented from rotating with respect to the outer cylinder 7 in a fitted state at each fitting position.

  In other words, a plurality of insertion grooves 30 a are provided on the inner peripheral surface of the outer cylinder 7 at regular intervals in the circumferential direction, and protrusions 30 b are provided on the outer peripheral surface of the inner cylinder 8, so that the inner cylinder 8 is fitted into the outer cylinder 7 in the circumferential direction. By inserting the protrusion 30b into any insertion groove 30a among the plurality of insertion grooves 30a provided on the inner cylinder 8, the inner cylinder 8 is fitted at any position among the plurality of positions rotated in the circumferential direction with respect to the outer cylinder 7, and this insertion is performed. The state is held by fitting the protrusion 30b into the insertion groove 30a, and is prevented from rotating in the circumferential direction in the insertion state. Accordingly, the insertion groove 30a and the projection 30b constitute stopper means 30 for preventing the inner cylinder 8 from rotating with respect to the outer cylinder 7 in the fitted state at each fitting position. Note that the insertion grooves 30 a may be provided on the outer peripheral surface of the inner cylinder 8 at regular intervals in the circumferential direction, and the protrusions 30 b may be provided on the outer peripheral surface of the outer cylinder 7.

  Then, when the inner cylinder 8 is fitted into the outer cylinder 7 embedded under the floor surface 4 by being fitted into the hole 3 provided in the floor surface 4, which insertion groove 30 a among the plurality of insertion grooves 30 a provided in the circumferential direction is inserted. The position of the guide pin 5 provided eccentrically with respect to the center of the inner cylinder 8 is adjusted by selecting whether or not the protrusion 30b is to be fitted, but after the adjustment (that is, in a completely fitted state), the insertion is performed. Since the inner cylinder 8 is prevented from rotating with respect to the outer cylinder 7 by the stopper means 30 comprising the groove 30a and the protrusion 30b, the position of the guide pin 5 can be reliably held at the correct position after adjustment. It is.

  Moreover, in this case, as shown in FIG. 8, the stopper means 30 is released so that the inner cylinder 8 is rotatable with respect to the outer cylinder 7 before the inner cylinder 8 is pulled up and completely pulled out from the outer cylinder 7. It has come to be. That is, as shown in FIG. 8 (b), the inner cylinder 8 is pulled up and the locking claw portion 16 resists its elasticity and is released from the lower end of the outer cylinder 7. A rotation space K from which the insertion groove 30a of the stopper means 30 is removed so that the locking claw portion 16 is rotatable within the outer cylinder 7 in a stage before being completely pulled out from the outer cylinder 7. Then, in the inner peripheral part of the outer cylinder 7, a range of dimension H) from which the protrusions between the insertion grooves 30 a are removed is formed on the inner peripheral surface of the outer cylinder 7.

  In the guide pin position adjusting method here, as shown in FIG. 8B, the operation tool M that attracts the magnet 20 provided at the upper end portion of the guide pin 5 by its magnetic force is brought close to the upper end portion. By causing the guide pin 5 to protrude from the guide pin insertion hole 9 of the inner cylinder 8 and rotating the inner cylinder 8 pulled up with the guide pin 5 in this protruding state to the outer cylinder 7, The position of the guide pin 5 in plan view is adjusted. In that case, the said latching claw part 16 can be smoothly rotated in the rotation space K without trouble. Note that the operating tool M for attracting the magnet 20 provided at the upper end of the guide pin 5 is a magnetic body such as an iron plate, even if it is a magnet having a pole different from the pole on the upper surface side of the magnet 20. Is also good.

  Further, as already described, the protrusion 12 for biting is provided in the circumferential direction of the outer peripheral surface portion of the outer cylinder 7 so that the outer cylinder 7 bites into the inner wall surface of the hole 13 so that the outer cylinder 7 does not come out of the hole 13. ing. However, when the biting projections 12 are provided in the circumferential direction of the outer peripheral surface portion of the outer cylinder 7, the upward protrusion can be reliably prevented. However, since the biting projections 12 are provided in the circumferential direction, the outer cylinder 7 is in the circumferential direction. There is a risk of rotating. Thus, when the outer cylinder 7 rotates in the circumferential direction, even if the position of the guide pin 5 is adjusted, the position of the guide pin 5 changes when the outer cylinder 7 rotates. 6, 7, and 9, the outer cylinder 7 is prevented from rotating by partially protruding a rotation-preventing protrusion 31 in the circumferential direction on the outer peripheral portion of the outer cylinder 7.

  In this case, a rotation-preventing protrusion 31 that protrudes further outward than the biting protrusion 12 is integrally formed on a part of the circumferential direction of the biting protrusion 12. As described above, when the rotation preventing projection 31 protrudes outward from a part of the circumferential direction of the biting projection 12, the rotation preventing projection 31 bites into the inner wall surface of the hole 13 and the rotation of the outer cylinder 7 can be prevented. Thus, the position of the guide pin 5 whose position has been adjusted can be prevented from changing, and the outer cylinder 7 can be prevented from coming off by the anti-rotation protrusion 31.

  Therefore, in the guide device for the suspension door of this embodiment, the circumferential fitting position of the inner cylinder 8 provided with the eccentric guide pin 5 with respect to the outer cylinder 7 can be varied. Even if there is an error in the embedded position of the outer cylinder 7, the position of the guide pin 5 in plan view can be simplified by changing the fitting position by rotating the inner cylinder 8 relative to the outer cylinder 7. And it can adjust reliably. Thereby, the plurality of guide pins 5 are positioned on a straight line on the floor surface 4 so as to correspond to the upper rail 2, so that the suspension door body 1 can smoothly run so that the lower end portion thereof does not rattle. Become.

  Further, as shown in FIG. 8, the inner cylinder 8 can be fitted at a plurality of positions rotated in the circumferential direction with respect to the outer cylinder 7, and the inner cylinder 8 rotates with respect to the outer cylinder 7 in the fitted state at each fitting position. Since the stopper means 30 is provided to prevent the inner cylinder 8 from being completely fitted, the inner cylinder 8 does not rotate with respect to the outer cylinder 7, and the position of the guide pin 5 is adjusted after the position is adjusted. Can be reliably prevented. Moreover, in this case, the stopper means 30 is released so that the inner cylinder 8 is rotatable with respect to the outer cylinder 7 before the inner cylinder 8 is pulled up and completely pulled out from the outer cylinder 7. Therefore, the inner cylinder 8 is rotated with respect to the outer cylinder 7 in a state where the stopper means 30 is released before the inner cylinder 8 is completely pulled out without being completely removed from the outer cylinder 7. Thus, the fitting position can be easily changed.

  Further, in the suspension door guide device of this embodiment, as shown in FIG. 4, an elastic locking claw portion 16 is suspended from the lower end portion of the inner cylinder 8, and this locking claw portion 16 is externally attached. By being locked to the lower end portion of the cylinder 7, the inner cylinder 8 in the fitted state is prevented from being pulled up with respect to the outer cylinder 7, and the unintentional detachment of the inner cylinder 8 is prevented. In this case, as shown in FIG. 8B, the inner cylinder 8 is pulled up so that the locking claw portion 16 resists its elasticity and is unlocked from the lower end portion of the outer cylinder 7. Before the cylinder 8 is completely pulled out from the outer cylinder 7, the rotation space K from which the stopper means 30 is removed so that the locking claw portion 16 can be rotated in the outer cylinder 7 is provided inside the outer cylinder 7. Since the inner cylinder 8 is rotated with respect to the outer cylinder 7 and the position of the guide pin 5 is adjusted by the rotation of the inner cylinder 8 with respect to the outer cylinder 7, the locking claw portion 16 has a rotation space in the inner peripheral area of the outer cylinder 7. The sliding movement can be smoothly performed at K, and the position adjusting operation of the guide pin 5 can be performed without any trouble.

  Further, in the guide pin position adjusting method of this embodiment, as shown in FIG. 8B, the operation tool M for attracting the magnet 20 provided at the upper end portion of the guide pin 5 by its magnetic force is provided at the upper end portion. By making them approach, the guide pin 5 can be easily protruded from the guide pin insertion hole 9 of the inner cylinder 8. The position of the guide pin 5 in plan view can be adjusted very simply by rotating the inner cylinder 8 pulled up with the guide pin 5 in the protruding state with respect to the outer cylinder 7.
