Description

  The present invention mainly relates to a door-to-door structure of a sliding door in an indoor joinery.

  There was a sliding door that separated the room by opening and closing the shoji. There are various sliding doors, such as sliding doors and one-sided sliding doors, depending on the number of paper sliding doors and their storage.

JP 11-280345 A

The above sliding door is provided with a stopper on the upper rail that stops the shoji at a predetermined position of the opening when the shoji is pulled. However, when the shoji is opened and closed with an unexpectedly strong force, inertia acts on the lower part of the shoji, with the upper end of the shoji that hits the stopper as a fulcrum, which may cause the shoji door to come off the lower rail. Furthermore, in the case of a sliding door with a height dimension, there is a case in which the shoji can be removed even by a light impact generated during opening and closing.
The present invention has been made in view of the above problems, and it is an object of the present invention to provide a sliding door contact structure that can reliably stop a shoji without being removed at a predetermined position when the shoji is opened and closed.

  The invention according to claim 1 of the present invention comprises a shoji, an upper rail, and a lower rail, and an upper stopper and a lower stopper are attached at positions where the rail grooves of the upper rail and the lower rail face each other. A lower stopper receiver is provided at a position where the lower stopper of the shoji comes into contact.

  The invention according to claim 2 of the present invention is characterized in that the lower stopper receiver protrudes downward from the lower end of the shoji according to the depression of the rail groove.

  According to a third aspect of the present invention, the lower stopper has a lower stopper member and a lower fixture, and the lower stopper member has a shape in which a contact point with the lower rail substantially coincides with the rail groove. The lower fixture is inserted through the lower stopper member and fixed to the lower rail, and the lower rail is provided with a locked portion for locking the tip of the lower fixture in the rail groove. It is characterized by

  According to the invention described in claim 1 of the present invention, when the shoji is opened and closed, the stopper receivers attached to the upper and lower ends of the shoji are used as stoppers attached at positions facing the upper and lower sides of the upper rail and the lower rail. It hits almost at the same time. As a result, when the opened and closed shoji hits the upper and lower stoppers, the impact received from each stopper is dispersed up and down the vertical fence. However, the shoji does not come off the upper and lower rails, and the shoji can be opened and closed stably.

  According to the second aspect of the present invention, the lower end portion of the lower stopper receiver protrudes downward in accordance with the recess of the rail groove. As a result, when installing the shoji, even if the distance between the lower edge of the shoji and the lower rail expands up and down by adjusting the door, the lower stopper receptacle protrudes downward according to the recess of the rail groove, The contact range becomes longer in the vertical direction, and a contact surface with the lower stopper is secured. From this, when the lower stopper protrudes to the lower end, the upward protrusion of the lower stopper from the lower rail can be reduced as much as possible, so that the indoor opening can be secured in a barrier-free state.

  According to the third aspect of the present invention, when the lower stopper member is fixed by the lower fixture, the tip of the lower fixture locks and pulls the locked portion of the rail groove, so that the lower portion The stopper member can be firmly fixed. In addition, the contact point between the lower stopper member and the lower rail is in close contact with the rail groove, so that when the lower stopper member is fixed, the fixed state between the lower stopper member and the lower rail is stable, and the shoji is opened and closed. The structure resists the impact of Furthermore, if the locked state between the lower fixture and the lower rail is released, the lower stopper can be moved to an arbitrary position in the longitudinal direction of the rail groove, and the lower fixture is again engaged with the rail groove at that position. If it stops, it becomes possible to adjust the attachment position of the lower stopper member.

  As shown in FIG. 3A, the upper rail 5 has rail grooves 5 a that are recessed upward substantially in a U-shape in the rail longitudinal direction of the upper rail 5. Further, the rail groove 5a of the upper rail 5 has a structure in which the groove opening is narrower than the other part, and the locking tool 9 of the shoji 1 that slides on the rail groove 5a cannot be removed. Further, an upper stopper 11 is attached to an arbitrary position of the upper rail 5 in the rail longitudinal direction. The upper stopper 11 can be fixed at an arbitrary position in the rail longitudinal direction of the upper rail 5. The upper stopper member 11 a that closes the rail groove 5 a and the groove of the rail groove 5 a that penetrates the upper stopper member 11 a up and down. It is comprised from the screw-type upper fixing tool 11b latched to the inner peripheral side of opening. Further, the upper stopper 11 is configured such that the tip of the upper fixture 11b is locked to the inner peripheral portion of the narrow groove opening of the rail groove 5a of the upper rail 5 by turning the upper fixture 11b in a screw manner. By pulling the fixture 11b and the upper rail 5 together, the rail groove 5a of the upper rail 5 can be positioned at an arbitrary position in the rail longitudinal direction. Further, as shown in FIG. 3 (b), the upper stopper member 11a has a catch portion 12 that is cut out in a substantially U-shape on the side in contact with the shoji 1 to lock the shoji 1 described later. The tool 9 is called into the catch portion 12 and fitted.

  As shown in FIG. 4A, the lower rail 6 has a rail groove 6a having a substantially Y-shaped cross section continuous in the rail longitudinal direction. Further, a holding groove (depression) 13 continuous along the rail groove 6a is provided at the substantially center of the rail groove 6a, and the holding groove 13 is formed deeper than the rail groove 6a.

  The lower stopper 16 is comprised from the lower stopper member 16a and the lower fixing tool 16b like FIG. 1 (a) and FIG. 4 (a) (b). The lower stopper member 16a has a block shape as a whole, and the portion where the lower rail 6 is positioned above the rail groove 6a is set to have a height that the door 10 of the shoji 1 cannot ride on. Further, the outer peripheral portions on both sides of the lower portion of the lower stopper 16 are provided with tapers 17 and 17 that gradually narrow downward, respectively, and the tapers 17 and 17 enter the Y-shape of the rail groove 6a of the lower rail 6. It is installed stably. Further, the lower stopper member 16a is provided with insertion holes 18 penetrating vertically at a plurality of positions spaced in the rail longitudinal direction of the lower rail 6. Further, the end of the lower stopper 16 on the side in contact with the shoji 1 has a contacted surface 21a that stands substantially vertically. When the lower stopper 16 is attached to the lower rail 6 as described above, the lower stopper member 16a is placed at an arbitrary position in the rail longitudinal direction of the lower rail 6, and the lower fixture 16b is inserted into the insertion hole 18. As a result, the tip end of the lower fixture 16 b is locked to the groove inner peripheral portion (locked portion) 28 of the holding groove 13. As a result, the lower stopper 16 is fixed so as not to be disengaged in the form in which the rail groove 6a of the lower rail 6 is closed in the traveling direction of the shoji 1.

  As shown in FIG. 1 (a) and FIG. 5 (a), the shoji 1 is a rectangular frame formed by an upper collar 1a, a lower collar 1b, and left and right vertical collars 1c, 1c. On the inner peripheral side of 1b and 1c, a panel 19, glass, a crosspiece and the like are arranged. Moreover, the latching tool 9 is attached to the upper end of the upper collar 1a. The upper part of the locking tool 9 projects in an enormous shape, and the enlarging part of the locking tool 9 enters the rail groove 5a of the upper rail 5 and is locked to the inner peripheral side of the rail groove 5a. The shoji 1 is structured not to come out of the upper rail 5. A lower stopper receiver 20 is attached to the lower end of the vertical rod 1c. The lower stopper receiver 20 closes the lower end of the vertical frame 1c, and further protrudes downward within a range straddling the lower end of the vertical rod 1c and a part of the lower end of the lower rod 1b. Moreover, it has the insertion part 25 inserted in the hollow part S of the vertical rod 1c in the upper part of the lower stopper receptacle 20 like FIG.5 (b) (c). Further, the lower stopper receiver 20 inserted into the lower end of the vertical rod 1c is fixed with a fixing screw 27 or the like screwed from below using a tapping hole 26 in the hollow portion S of the vertical rod 1c. Moreover, the shape of the lower end part of the lower stopper receptacle 20 is substantially Y-shaped. Specifically, it has an inclined portion 20a that substantially coincides with the rail groove 6a (substantially Y-shaped in cross section) of the lower rail 6, and protrudes downward between the inclined portions 20a on both sides to hold the holding groove 13 of the lower rail 6. It has a shoji lower end projection 8 that enters. Further, the lower stopper receiver 20 has an abutting surface 21b that stands substantially vertically on the side that abuts the lower stopper 16.

  When formed in this way, as shown in FIGS. 6A and 6B, the contact surface of the lower stopper receiver 20 of the shoji 1 that slides along the rail groove 6a of the lower rail 6 when the shoji 1 is opened and closed. 21 b abuts against the abutted surface 21 a of the lower stopper 16. At this time, since the contact surface 21b of the lower stopper receiver 20 contacts the contacted surface 21a of the lower stopper 16, the contacted surface 21a and the contact surface 21b are perpendicular to each other when the sliding door 1 hits the door. Since the surfaces are received by each other, the reaction force of the impact is not dispersed, and the shoji 1 is not detached from the rail groove 6a of the lower rail 6 during opening and closing. Therefore, even if it is the special shoji 1 which has a long height dimension like this embodiment, the opening / closing operation | movement of the shoji 1 can be stabilized. Further, as shown in FIGS. 7 (a) and 7 (c), the shoji lower end protruding portion 8 of the lower stopper receiver 20 has a shape that allows the rail groove 6a of the lower rail 6 to enter the holding groove 13 as follows. Such effects and effects will be exhibited. Even if the gap between the lower edge of the shoji 1 and the lower rail 6 is widened as shown in FIGS. 7B and 7D by the adjustment work when the shoji 1 is installed, the shoji 1 The contact surface 21b of the lower stopper receiver 20 provided in the lower end protruding portion 8 contacts the contacted surface 21a of the lower stopper 16. Thus, regardless of the state of the shoji 1 built, even if the height dimension of the lower stopper 16 from the lower rail 6 is lowered (in this embodiment, about 3 to 4 mm), the shoji lower end protrusion 8 Since the contact area of the contacted surface 21a can be expanded by lengthening the upper and lower forming ranges, the contact surface 21b of the lower stopper receiver 20 can be contacted. Accordingly, the height dimension of the lower stopper 16 from the floor surface G can be made as small as possible to meet the barrier-free standard. Further, the lower stopper receiver 20 has a shape substantially coinciding with the rail groove 6a, and the shoji lower end projection 8 is inserted into the holding groove 13, so that the shoji lower end projection 8 of the lower stopper receiver 20 is in the lower rail 6. It also serves as a guide for sliding the shoji 1 stably along the line.

  The door stop structure of the sliding door of the present invention does not limit the lower stopper 16 to the above embodiment. As shown in FIG. 8A, the insertion hole 18 is provided in the lower stopper member 16 a, and the nut 22 is disposed in the holding groove 13 of the lower rail 6. The screw 23 (lower fixture) is passed through the insertion hole of the lower stopper member 16a, and the nut (lower fixture) 22 is tightened with the screw 23, whereby the nut 22 is pulled and the lower stopper member 16a is moved to the lower rail 6 The retaining groove 13 is engaged with the inner periphery of the groove. Thereby, the lower stopper 16 can be fixed at an arbitrary position of the rail groove 6 a of the lower rail 6. Further, if the screw 23 is loosened to such an extent that the nut 22 cannot be removed, the locking state of the lower stopper 16 with the lower rail 6 is released, so that the lower stopper 6 can be moved to any position along the rail groove 6a. If moved, fine adjustment after attaching the lower stopper 16 can also be performed. Further, as shown in FIG. 8B, the lower stopper member 16a is arranged at an arbitrary position of the lower rail 6, and a wooden screw (lower fixing tool) 24, a nail or the like is driven into the upper end portion of the lower stopper member 16a. Thus, the lower stopper member 16a can be fixed to the rail groove 6a of the lower frame rail 6 by reaching the floor material. Further, as shown in FIG. 8C, the lower rail 6 has a flange portion 14 on the outer peripheral portion, and further has a stopper portion 15 continuous in a step shape at the lower portion of the flange portion 14. Can be used. If formed in this way, when the lower rail 6 is attached to the lower frame 3, the collar portion 14 is locked to the lower frame 3, and further lowering of the lower rail 6 is prevented. Furthermore, the retaining portion 15 bites into the lower frame 3 and the fixed state between the lower rail 6 and the lower frame 3 can be strengthened.

  In the above-described embodiment, the door stop structure of the sliding door according to the present invention is formed in a substantially Y shape because the lower end of the lower stopper receiver 20 has the shoji lower end protrusion 8. It is sufficient that the portion has a shape corresponding to the recess 13 of the rail groove 6a or extends downward from the rail groove 6a. This is because, when the installation of the shoji 1 is adjusted, even if the gap between the lower end of the shoji 1 and the rail groove 6a is widened, if a part of the lower stopper receiver 20 comes into contact with the lower stopper 16, This is because it functions as a door-to-door means when the shoji 1 is opened and closed. Furthermore, although the recess 13 for positioning the lower end of the lower stopper receiver 20 below the rail groove 6a is formed in a groove shape like the holding groove 13 in the above embodiment, it may be a hole, a notch or the like. Further, the lower fixture 16b is not limited to fixing means such as screws and screws as long as the lower stopper member 16 can be fixed to the rail groove 6a of the lower rail 6. Moreover, the upper stopper 11 should just be fixed to the position which opposes the lower stopper 16 fixed to the arbitrary positions of the rail longitudinal direction of the lower rail 6 up and down. Furthermore, if the upper stopper 11 stops the sliding of the shoji 1 in the fixed arbitrary positions, the shape and magnitude | size will not be limited.
