Description

  The present invention is used, for example, in the lower part of a suspended door such as a sliding sliding door, a sliding door, and a retractable partition panel, and in particular, a retractable guide that guides its movement while preventing the swinging of the lower side of various hanging doors. It relates to the device.

  Under the suspension door as described above, the upper part of the suspension door is usually suspended freely through an upper rail and a runner provided on the ceiling side in order to guide its smooth opening and closing movement. The lower part is also supported by the lower rail and pivot provided on the floor side so that it can run freely, and when the door is opened and closed, it prevents the swinging door itself from shaking greatly and ensures the smooth movement of the door. It has a structure. (For example, refer to Patent Document 1).

  However, laying the lower rail continuously on the floor side inevitably creates a groove on the floor surface, so when the hanging door is open, Alternatively, the heel of the high heels was depressed, and the appearance was not favorable.

  Therefore, instead of the lower rail, a concave traveling groove is continuously formed on the lower end surface of the suspension door, and a guide roller that slides in the traveling groove is erected on the floor surface side. A guide device has been proposed for guiding the movement of the lower part of (see, for example, Patent Document 2).

  However, guiding the lower part of the hanging door freely with the guide roller does not cause the heel of the high heel to fall like the lower rail, but this time the guide roller itself will rise significantly from the floor, After all, he crawled and fell, or the appearance was bad. Therefore, it can be considered that the guide roller is detachably attached to the floor surface, and the guide roller is removed from the floor surface when the hanging door is in an open state.In this case, the guide roller is removed and stored one by one. Because it had to be done, the work was extremely troublesome and could not be said to be realistic.

  The present invention was developed in order to effectively solve the problems of such a conventional guide device, and the invention according to claim 1 is suspended so as to be able to run on the ceiling side and has a running groove on its lower end surface. A sliding door guide device formed with an outer cylinder inserted and fixed in a mounting hole drilled in the floor, an inner cylinder fitted and fixed to the inner side of the outer cylinder, and an inner side of the inner cylinder And a spring that elastically biases the lift cylinder upward, and the lift cylinder is disposed between the inner cylinder and the lift cylinder against the biasing force of the spring. A first locking means for removably locking the upper end of the lifting cylinder in a lowered position where the upper end surface is flush with the floor surface, and the upper cylinder protrudes from the floor surface by the urging force of the spring so that the upper portion projects from the floor groove. And a second locking means for releasably locking at the raised position inserted into the .

  According to a second aspect of the present invention, on the premise of the first aspect, a guide roller that slides along the side surface of the traveling groove is attached to the upper part of the lifting cylinder.

  The invention described in claim 3 is based on the premise of claim 1 and is characterized in that the upper shape of the elevating cylinder is formed as a guide pin that can move in the running groove.

  According to a fourth aspect of the present invention, on the premise of the first to third aspects, an operation groove for locking and unlocking the first and second locking means is formed on the upper end surface of the lifting cylinder.

  Therefore, in the first aspect of the invention, when the lifting cylinder is stored in the inner cylinder against the biasing force of the spring when the suspension door is opened, the upper end surface of the lifting cylinder is flush with the floor surface. Since the device itself is completely hidden in the floor surface by being locked in the lowered position via the first locking means, it is crushed and rolled or the appearance is damaged as in the conventional case. No fear. Also, when opening and closing the suspension door, if the storage lock state of the lifting cylinder is released, the upper part of the lifting cylinder protrudes upward from the inner cylinder by the urging force of the spring and is locked at its raised position via the second locking means. Therefore, it is possible to reliably guide the traveling of the hanging door at the upper part of the lifting cylinder inserted into the traveling groove.

  In the invention described in claim 2, since the guide roller is attached to the upper part of the lifting cylinder, the guide roller slides along the side surface of the running groove of the suspension door, and in particular, the smooth side of the lower side of the suspension door is smooth. We can guarantee traveling.

  In the invention according to claim 3, since the upper shape of the lifting cylinder is a guide pin shape, smooth running on the lower side of the hanging door can be expected.

  In the invention according to claim 4, since the operation groove for locking and unlocking the first and second locking means is formed on the upper end surface of the elevating cylinder, the elevating cylinder is moved to its lowered position and elevated position. Can be easily locked and unlocked.

It is a longitudinal cross-sectional view which shows the state which the guide apparatus itself was hidden inside the floor surface. It is a longitudinal cross-sectional view which shows the state which guide device itself protrudes upwards and guides the opening / closing movement of a hanging door.

  The present invention presupposes a guide device for a suspension door that is suspended so as to be able to travel on the ceiling side and has a traveling groove formed on the lower end surface thereof, and an outer cylinder that is inserted and fixed in a mounting hole formed in the floor surface; An inner cylinder fitted and fixed to the inner side of the outer cylinder, an elevating cylinder arranged to be movable up and down inside the inner cylinder, and a spring that elastically biases the elevating cylinder upward, A first locking means for storing the elevating cylinder in the inner cylinder against the urging force of the spring between the elevating cylinder and releasably locking it in a lowered position where the upper end surface thereof is flush with the floor surface; When the lifting door is opened by providing a second locking means that releasably locks the lifting cylinder in the raised position where the upper part protrudes from the floor surface by the biasing force of the spring and is inserted into the traveling groove. Because the guide device itself is hidden in the floor, it crawls and falls like before. , The concern is eliminated external appearance of the motorcycle is impaired, remove from the floor, completely eliminates the need to store.

  Hereinafter, if the present invention is described in detail based on a preferred embodiment illustrated in the drawings, the retractable guide device according to the embodiment has been developed particularly for smoothly guiding traveling on the lower side of various suspension doors. As shown in FIG. 1, the specific structure of the outer cylinder 1 is inserted and fixed in a mounting hole 16 drilled in the floor surface F, and the inner cylinder 1 is fitted and fixed inside the outer cylinder 1. The cylinder 2, the elevating cylinder 3 arranged to be movable up and down inside the inner cylinder 2, the compression coil spring 4 that constantly urges the elevating cylinder 3 upward, and the lower end surface of the suspension door D to be described later A guide roller 5 that slides on the formed traveling groove 15, a support shaft 6 that rotatably attaches the guide roller 5 to the upper part of the elevating cylinder 3, and a lid plate 7 that closes the lower opening of the outer cylinder 1 are provided. Is.

  Therefore, these will be described in detail. First, as shown in FIG. 2, the outer cylinder 1 is formed with a locking surface 8 having a serrated longitudinal section on the lower outer peripheral surface thereof, 8 is engaged with the inner peripheral surface of the mounting hole 16 of the floor surface F, so that the outer cylinder 1 inserted into the mounting hole 16 is prevented from coming off. Further, the height of the outer cylinder 1 is given such a dimension that the upper end opening edge thereof is flush with the floor surface F in a state where the outer cylinder 1 is completely inserted into the mounting hole 16 formed in the floor surface. ing.

  Further, the inner cylinder 2 is formed into a complete cylindrical shape, and as shown in FIG. 3, a pair of stopper projections 13 projecting from the elevating cylinder 3 which will be described later are engaged at intervals of 90 ° on the side wall. Two short slits 9 and two long slits 10 having different heights are alternately formed in the axial direction, and the pair of short and long slits 9 and 10 are connected to each other via a connecting slit 11. Yes.

  As shown in FIG. 4, the elevating cylinder 3 has an annular inward flange 12 that forms a seat for the spring 4 on the inner periphery of the upper end opening, and a pair of stopper protrusions 13 that face the outer peripheral surface of the lower part. It is configured to project. Therefore, when the elevating cylinder 3 is arranged to be movable up and down in the inner cylinder 2 and each stopper projection 13 is engaged with the edge of the short slit 9 of the inner cylinder 2, the elevating cylinder 3 is supported by the guide roller 5. When the stopper projection 13 is engaged with the edge of the long slit 10 of the inner cylinder 2 when the stopper projection 13 is locked in the fully lowered position with the shaft 6, the elevating cylinder 3 is connected to the guide roller 5 and the support shaft. 6, the short slit 9 and the stopper projection 13 serve as the first locking means, and the long slit 10 and the stopper projection 13 serve as the second locking means. The locking means will be configured.

  As shown in FIG. 5, the support shaft 6 includes a disc-shaped head 6 a and a leg portion 6 b whose tip surface is recessed in a conical shape, and the tip of the leg portion 6 b is caulked and expanded via a punch. By joining the upper end opening edge of the elevating cylinder 3 and cooperating with the disk-shaped head 6a, the guide roller 5 is rotatably attached to the elevating cylinder 3, and at the center of the disk-shaped head 6a, An operation groove 14 for the first lock means and the second lock means is formed. Therefore, the upper end surface of the lifting cylinder 3 substantially corresponds to the disk-shaped head 6a of the support shaft 6.

  The cover plate 7 that closes the lower opening of the outer cylinder 1 is for housing and holding the spring 4, the elevating cylinder 3, and the inner cylinder 2 inside the outer cylinder 1, but in a state where the lower opening of the outer cylinder 1 is closed. In addition, the structure is also used as a receiving seat at the end of the spring 4.

  As for the hanging door D, as in the prior art, it is suspended on the ceiling side via an upper rail (not shown) and a runner (not shown). As shown in FIG. 6, a concave running groove 15 is continuously formed in the longitudinal direction of the lower end surface, and the side surface of the running groove 15 is slid on the guide roller 5 attached to the upper part of the lifting cylinder 3. By this, the structure which can guide opening and closing movement of the suspension door D is provided.

  Therefore, when assembling such a guide device, when the inner cylinder 2 is externally fitted to the lifting cylinder 3 from the outside while the stopper projections 13 of the inner cylinder 2 and the short slits 9 or the long slits 10 of the lifting cylinder 3 are matched. Since the elevating cylinder 3 is disposed so as to be movable up and down with respect to the inner cylinder 2, the spring 4 is set between the inward flange 12 of the elevating cylinder 3 and the cover plate 7, and the inner cylinder is left as it is. When 2 is inserted and fixed inside the outer cylinder 1, the device itself can be easily assembled. As a result, the elevating cylinder 3 is pushed upward by the urging force of the spring 4.

  Therefore, in actual use, if the outer cylinder 1 is inserted into the mounting hole 16 drilled in the floor surface F, and the outer cylinder 1 is fixed in the mounting hole 16 via its locking surface 8. In this case, the stopper projection 13 on the lifting cylinder 3 side engages with the edge of the short slit 9 on the inner cylinder 2 side against the urging force of the spring 4. 7, the elevating cylinder 3 is locked at its lowered position with the guide roller 5 and the support shaft 6, and the disc-shaped head of the support shaft 6 that forms the upper end surface of the elevating cylinder 3. 6a is flush with the floor surface F. In this embodiment, unlike the conventional case, not only the elevating cylinder 3, but also the disc-shaped head 6a of the guide roller 5 and the support shaft 6 is provided in the inner cylinder 2. And no longer protrudes upward. For this reason, even if the hanging door D is in the open state, it can be prevented from rolling and falling as in the prior art, and the appearance can be prevented from being damaged.

  Conversely, when opening and closing the suspension door D, if the tip of a coin or a flat-blade screwdriver is inserted into the operation groove 14 formed in the disc-shaped head 6a of the support shaft 6 and rotated 90 ° in a predetermined direction, Accordingly, the rotation of the elevating cylinder 3 is obtained, and the pair of stopper protrusions 13 engaged with the end edges of the respective short slits 9 are transferred into the corresponding long slits 10 via the connecting slits 11. However, this time, the biasing force of the spring 4 causes the pair of stopper projections 13 to engage with the edges of the long slit 10 to lock the elevating cylinder 3 in the raised position. Therefore, as shown in FIG. With the support shaft 6, the elevating cylinder 3 protrudes upward from the mounting hole 16. For this reason, since the guide roller 5 subsequently enters the running groove 15 of the suspension door D and slides on its side surface, the opening / closing movement of the suspension door D is guided and the lower side of the suspension door D is guided. The swinging of the suspension door D can be effectively prevented when the suspension door is closed.

  Similarly, when changing from the locked state at the raised position to the lowered position, the lifting cylinder 3 is forcibly pushed into the inner cylinder 2 against the urging force of the spring 4, and similarly, the support shaft 6 side. When the tip of a coin or a flat-blade screwdriver is inserted into the operation groove 14 and rotated 90 ° in the reverse direction, each stopper projection 13 engaged with the edge of the long slit 10 is now passed through the connecting slit 11. Since the engagement lock is performed on the edge of the short slit 9, the guide device itself can be hidden again inside the floor F.

  Note that, under the above-described embodiment, a configuration is adopted in which the guide roller 5 is attached to the upper side of the lifting cylinder 3 and the side of the running groove 15 is slid to guide the running of the suspension door D. However, the present invention is not limited to this, and although not specifically illustrated, the guide roller 5 and the support shaft 6 may be omitted, and the upper part of the elevating cylinder 3 may be moved in the traveling groove 15. It goes without saying that the same effect can be obtained even when the guide pin shape is obtained.

  Since the retractable guide device according to the present invention does not protrude upward from the floor surface under the open state of the suspension door, it may be rolled and rolled as in the conventional case, and the appearance may be damaged. As a result, if this is applied to a continuous sliding door, a sliding door, a storage partition panel, etc., it will be very convenient.
