Description

  According to the present invention, a lifting body that is retractable in a prepared hole recessed in a floor surface on which a sliding door travels is engaged with a traveling groove formed on a lower end surface of the sliding door in a projecting state, and the sliding door is not shaken. The present invention relates to a sliding door guide device that guides the vehicle so that it goes straight.

  Conventionally, this type of sliding door guide device is provided with recessed holes at intervals on the floor surface on which the sliding door travels. When a magnetized body having magnets is disposed on the door end side and the door bottom side of the long and slender running groove provided in the lower end surface of the door, and when the magnetized body reaches the floor side lifting body when opening and closing the sliding door A structure is known in which a lifting body is pulled up by a magnetic force and engaged with a running groove, and the sliding door is guided so as to go straight without swinging (see Patent Document 1). In this sliding door guide device, a locking projection is provided on the outer peripheral surface of the case, and the locking projection is locked to the inner peripheral surface of the pilot hole so that the case of the lifting body is embedded and fixed on the floor surface. It has a structure.

  In this sliding door guide device, in general, the indoor floor surface is often made of a wood material, but recently, with the increase in apartments, the floor surface is often constructed with an RC base instead of a wood material. Since it is concrete, it is difficult to accurately form a pilot hole in a desired size and shape. Therefore, the pilot holes formed in the concrete floor surface are inaccurate in size and shape, and the inner peripheral surface is rough and hard. Therefore, when the case is accommodated in such a prepared hole as it is, the locking projection on the outer peripheral surface is not easily locked to the hard inner peripheral surface of the prepared hole, so the case is not securely embedded and fixed on the floor surface. There was a problem

  Therefore, in a conventional sliding door guide device, as shown in FIG. 8, for example, a substantially cylindrical holding member 2 made of synthetic resin is fixed in a prepared hole 1 recessed in a concrete floor surface f. Since the case 4 containing the elevating body 3 is accommodated in the holding member 2, the locking projection 5 a formed on the outer peripheral surface of the outer cylinder 5 of the case 4 is engaged with the inner peripheral surface of the pilot hole 1. There is one in which the case 4 is securely embedded and fixed to the floor surface f by stopping (see Patent Document 1).

  However, in the conventional sliding door guide device, since the holding member 2 is formed of a synthetic resin, the locking protrusion 5a of the case 4 is locked into the inner peripheral surface of the holding member 2 so that the case 4 comes off. Although it is embedded and fixed in the holding member 2 so as not to come off, in this case, when an impact or a side pressure is applied to the sliding door during traveling, the case 4 may be strongly fixed in the holding member 2 at that time. There was a problem that when the floor surface was made of mortar having a lower strength than concrete, the floor surface was damaged by cracking or cracking or cracking.

  Therefore, an object of the present invention is to provide a safe sliding door guide device that does not damage mortar and the like when the floor surface is made of mortar whose strength is lower than that of concrete even when impact or side pressure is applied during traveling of the sliding door. There is to do.

The invention according to claim 1 is, for example, as shown in the embodiment shown below, of a floor side guide g2 that is slidably provided in a prepared hole 16 that is recessed in a floor surface F2 under a track on which the sliding door 10 travels. In the sliding door guide device G that guides the traveling of the sliding door 10 by engaging the elevating body 15 in a protruding state with the traveling groove 11 of the door side guide g1 formed on the lower end surface 10a of the sliding door 10, the floor side guide g2 is: A fitting means 13 is formed by a cylindrical body having an upper end opening, and a flanged flange 19a extending outwardly from the inner edge 19 of the opening is formed, and the flanged flange 19a is locked to the hole edge and fixed in the pilot hole 16. And a case 14 that is fitted into the fitting means 13 with a cylindrical body having an upper end opening that incorporates the elevating body 15, and a gap S is formed between the case 14 and the inner peripheral surface 20 of the fitting means 13. Possible to fit the case 14 in the resulting loose fit Disposed on, Te on the inner peripheral surface 20 to gradually thin in accordance with the thickness in the inner peripheral surface 20 for fitting the case 14 toward the opening inner edge 19 - the path provided between the casing 14 The gap S is formed between them.

  According to the first and second aspects of the present invention, in the floor side guide, the fitting means is movably disposed on the inner peripheral surface by fitting the case in a loose fitting state in which a gap is formed between the fitting means and the case. Therefore, when traveling, when the sliding door is squeezed and a side pressure is applied, the case moves in the gap and disengages from the fitting means, so that the shock is buffered. As a result, the case is strong in the fitting means. Regardless of being in a fixed state, even when the floor surface is made of mortar or the like whose strength is lower than that of concrete, the mortar or the like can be prevented from being broken and damaged.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 shows a sliding door guide device that is an example of the present invention in a state in which a projecting lift body engages with a running groove to guide the running of the sliding door, and FIG. 2 shows a floor side guide of the same sliding door guide device. Shown in the stowed state of the lifting body. In the illustrated example, when the sliding door 10 engaged with a sliding door rail (not shown) fixed on the ceiling side is suspended in the opening / closing direction so as to be able to travel freely, and when the sliding door 10 travels to open and close the opening, The sliding door guide device G according to the present invention is operated to guide the sliding door 10 traveling in the opening / closing direction on the floor surface F2 so as to go straight without swinging.

  The sliding door guide device G includes a door side guide g1 provided in the traveling groove 11 and a floor side guide g2 provided on the floor F along the length direction of the lower end surface 10a of the sliding door 10. The door-side guide g1 includes a pair of magnetic attachment means (not shown) provided in the recessed grooves 11a at both ends in the traveling groove 11, and a guide rail 12 laid in an intermediate recessed groove between the both end recessed grooves. The magnetizing means includes a magnet, and a lifting and lowering body 15 (to be described later) of the floor side guide g2 is projected by a magnetic force. The lifting and lowering body 15 of the floor side guide g2 in the protruding state is engaged with the running groove 11 of the sliding door 10 to slide the sliding door. Guide 10 runs.

  On the other hand, a plurality of floor-side guides g2 are provided at intervals on the floor F under the track on which the sliding door 10 travels, and each of the floor-side guides g2 can be inserted into and retracted from the fitting means 13, the case 14 fitted to the fitting means 13, and the case 14. The elevating body 15 is provided. The floor F in the illustrated example is constructed of a floor main body F1 made of mortar, and a floor surface F2 is formed by spreading a vinyl chloride sheet on the floor main body F1. In the floor F, a pilot hole 16 is previously recessed at an interval on a floor surface F2 below the track on which the sliding door 10 travels.

  As shown in FIGS. 3, 4 and 5, the fitting means 13 is integrally formed of a resin in a bowl-like cylindrical shape with an upper end opening, and has a bowl-like bowl-shaped latching portion 17 on the lower side and an upper side. The holding part 18 is comprised. The latching portion 17 has a large number of hooking claws 17a projecting obliquely upward on the outer periphery, and a boss portion 17b having an internal threaded hole standing upright. The holding part 18 has an octahedron inner periphery and forms a flanged flange 19a extending outwardly on the opening inner edge 19 on the upper side in the figure, but is not related to the boundary position with the latching part 17 on the lower side in the figure. A stop portion 21 is formed. Therefore, the holding portion 18 is formed by gradually reducing the thickness of the inner peripheral surface 20 from the locking step portion 21 toward the opening inner edge 19 and attaching the tape to the inner peripheral surface 20. It is set as the structure which provides the clearance gap S between the case 14 fitted by. On the other hand, the opening inner edge 19 is formed in a step shape between the outer periphery flange 19a and a step h is provided therebetween. The step h is set to a height at which the annular flange portion 14b does not protrude beyond the flange-shaped flange 19a when the case 14 is fitted to the holding portion 18 and the annular flange portion 14b is placed on the opening inner edge 19 and locked. .

  The case 14 is made of resin, has both upper and lower ends opened, and the case body portion 14a whose outer periphery is octahedral in accordance with the inner shape of the fitting means 13, and the projecting opening 22 opened at the upper end in the figure of the case body portion 14a. And a flat annular flange 14b extending in a circular bowl shape from the opening edge. The case main body portion 14 a is overlapped with the inner side to form a cylindrical guide hole 23 whose upper opening is a projection port 22. The guide hole 23 is formed by a rotation restricting hole having a D-shaped cross section with a flat surface 23b in a part of the circumferential wall 23a, and a retaining jaw portion 23c projecting inwardly at the circumferential portion at the opening edge of the projection port 22. To do. Further, the case main body 14a has a connecting claw 14c projecting outwardly at the opposite portion of the lower end of the outer wall. On the other hand, the annular flange portion 14b is provided with a guide groove 29 that is gradually lowered toward the opening edge of the protruding port 22 connected to the flat surface 23b of the guide hole 23.

  The elevating body 15 includes a cylindrical first convex member 24 that is nested and incorporated in the guide hole 23 of the case 14, and a pin-shaped second convex member 25 that is nested and incorporated in the first convex member 24. It consists of.

  The first convex member 24 is a resin cylindrical body partially passing through a rotation restricting hole having a D-shaped cross section having a flat surface 24 a so as to match the guide hole 23 of the case 14. The part 24b is projected outward. The second convex member 25 is made of a metal magnetic material having a cap-shaped screw with a head portion 25a at the front end on the upper side in the figure, and has a retaining ring 26 on its end surface on the outer periphery of the base end. .

  Therefore, the floor-side guide g2 is first inserted by inserting the second convex member 25 into the first convex member 24 from the projecting opening 27, and then fitting the retaining ring 26 into the circumferential groove to prevent the floor-side guide g2. Then, the second projecting member 25 is nested in the first projecting member 24 so as to be retractable from the projecting port 27 to assemble the elevating body 15. Then, the elevating body 15 is fitted into the guide hole 23 of the case 14 from the lower opening 28. At that time, in a state where the first convex member 24 is positioned and held, the first convex member 24 is nested in the guide hole 23 so as to be protruded and retractable from the protruding port 22.

  As shown in FIG. 1 and FIG. 2, the fitting means 13 is provided with an adhesive, a sealing agent, and caulking in a pilot hole 16 that is previously recessed with a space on the floor surface F <b> 2 below the track on which the sliding door 10 travels. Filler 30 such as an agent is injected, fitted in an uncured state, and hooked claws 17a... Further, the boss portion 17 b of the latching portion 17 is screwed into the hole bottom 16 a with the set screw 35. Then, the fitting means 13 is fixed in the prepared hole 16 as the filler 30 is cured. Next, the case main body portion 14a is fitted into the fitting means 13 in the pilot hole 16 and placed on the boss portion 17b, while the annular hook 14b is placed on the inner edge 19 of the opening and locked, and the coupling claw 14d. The case 14 is fitted to the holding portion 18 of the fitting means 13. At that time, the fitting means 13 fits the case 14 on the inner peripheral surface 20 of the holding portion 18 in a loosely fitting state in which a gap S is formed between the case main body portion 14 a and the case 14. As described above, the floor side guide g2 is assembled and installed on the floor surface F1 under the track on which the sliding door 10 travels and moves.

  Therefore, in the sliding door guide apparatus G of the illustrated example, in the floor side guide g2, the opening inner edge 19 of the fitting means 13 is formed in a step shape between the outer periphery of the flanged flange 19a, and the step h is provided therebetween. When the case 14 is fitted to the holding portion 18 and the annular flange 14b is mounted, the step h is set to a height at which the annular flange 14b does not protrude beyond the flange 19a. Since the case 14 in which the body 15 is stored does not protrude higher than the flanged flange 19a of the fitting means 13, the floor surface F2 has almost no bulge that hinders walking, and safety can be improved.

  Now, in the sliding door guide device G, when the sliding door 10 is running, as shown in FIG. 7A, the second convex member 25 and the first convex member 24 of the lifting body 15 are generated by the magnetic force of the magnet of the door side guide g1. Are sequentially raised from the projecting opening 22 of the case 14 of the floor side guide g2, and the head 25a of the second convex member 25 is engaged with the guide rail 12 of the running groove 20 as the sliding door 10 runs. Then, the sliding door 10 is guided so as to go straight in the opening / closing direction. However, when the sliding door 10 is beaten and a side pressure P is applied during traveling, it is a disaster that the case 14 is in a strongly fixed state, and the floor main body F1 is stronger than concrete as in the illustrated example. If the mortar consists of falling mortar, the mortar, tile carpet or vinyl chloride sheet may crack or crack and break the floor.

  However, in the sliding door guide device G of the present invention, in the floor side guide g2, in particular, the fitting means 13 is in a loose fitting state in which a gap S is formed between the inner peripheral surface 20 of the holding portion 18 and the case main body portion 14a. Since the case 14 is fitted and movably disposed, when traveling, for example, as shown in FIG. 7 (B), when the sliding door 10 is beaten and the lateral pressure P is applied, the case 14 has a gap S accordingly. The shock is buffered by loosening and disengaging from the holding portion 18 of the fitting means 13, and as a result, the floor surface F1 is more than concrete, regardless of whether the case 14 is firmly fixed in the fitting means 13. Even in the case of mortar having a reduced strength, it is possible to prevent the mortar from being broken and broken.
