BACKGROUND OF THE INVENTION
The present invention is a sliding door that moves while being guided by the upper and lower rails, but about the sliding door device that can be allowed to stop at an arbitrary position.
[0002]
[Prior art]
In the case of doors such as entrances, when the lever is operated, the lifting and lowering bar provided in the door moves up and down when the lever is operated, so that the door does not move by inserting the tip into a hole provided on the floor or ceiling. Such a locking mechanism has been known for a long time. There is also an application of this, with a stopper provided at the tip of the lifting rod via a spring, and the door can be stopped at any position by pressing the stopper against the floor with the force of the spring ( For example, see Patent Document 1.) Even in the telescopic gate, it is generally performed to lock the raising / lowering rod by dropping it into a hole in the ground, and there is one that can be stopped at an arbitrary position (for example, see Patent Document 2). However, in a general sliding door that moves while being guided by the upper and lower rails, it can be stopped at any position even without a stopper due to its own weight and frictional force with the rail. It was never provided. There are cases where free-stoppers are provided on the upper-sliding type sliding doors, but they mainly control the rotation of the pulley that travels on the upper rail, which may cause the pulley to run idle or slide on the rail. The structure was also complicated.
[0003]
As disclosed in Patent Document 3, the present applicant is mainly used for blindfolding of a veranda such as an apartment, and uses a sliding door type movable covering device that uses a handrail of the veranda as a lower rail. Developed. In the sliding door constituting this movable covering device, since it is installed outdoors and the weight is made as light as possible, a stopper (clamping means in the same document) is used to prevent it from moving freely by wind or the like. Equivalent to This stopper presses both sides or the upper part of the handrail. As a specific configuration, the stopper presses the side surface of the handrail with the tip of the knob-attached bolt.
[0004]
As described above, when the sliding door is fixed by pressing the tip of the bolt with knob against the side surface of the handrail, the sliding door is slightly undesirably tilted. This is not the case when the tip of the bolt with knob is pressed against the upper surface of the handrail, but the sliding door is not fixed enough because it is pressed by one point on the head of the bolt, and the sliding door may flutter during strong winds. In addition, when the handrail is pressed with the tip of the knob-attached bolt, the handrail may be dented or damaged, and turning the knob-attached bolt is not good in terms of operability.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 to 3 show an embodiment of the sliding door device of the present invention. This sliding door device is constructed on a handrail 5b of a veranda such as an apartment, an apartment, etc., and the sliding door 1 is suspended on a top rail 5a fixed to the ceiling by a pulley 8 so as to be movable in the horizontal direction along the rail. The sliding door lower arm 9 is formed in a U-shaped cross section, and is positioned so as to surround the handrail 5b from above. The sliding door 1 is a rectangular frame formed by left and right vertical rods 2 and 2 and an upper rod 10 and a lower rod 9, and a plurality of slats 11 are vertically spaced in the frame. Can be used by appropriately moving along the handrail 5b in order to block the line of sight from the light, or block sunlight and wind. The vertical door 2 of the sliding door is provided with a free stopper 12 that fixes the sliding door 1 at an arbitrary position so that the sliding door 1 does not move freely by wind or the like.
[0011]
As shown in FIGS. 2 and 3, the free stopper 12 includes a French drop 3 installed on the interior side of the vertical shaft 2, a lift bar 4 that moves up and down by operating the operation lever 13 of the French drop, It is comprised with the press body 6 which is provided in the lower end part of the dropping bar 4, and presses the handrail 5b. The French drop 3 is generally installed on a door or the like, and the movable portion 14 moves up and down with a certain stroke by rotating the operation lever 13 up and down. The lifting rod 4 has a stroke absorbing mechanism 16 using a coil spring 15. Since the distance s between the pressing body 6 and the handrail 5b in the state of FIG. 3 (a) in which the raising / lowering bar 4 is raised is smaller than the stroke of the movable part 14, the raising / lowering bar 4 is lowered. In the state (b), the coil spring 15 is bent, and the pressing body 6 presses the handrail 5b by the repulsive force. By providing such a stroke absorbing mechanism 16, the function of stopping the sliding door is ensured even when the stroke of the movable portion 14 is constant and the gap s between the pressing body 6 and the handrail 5 b varies. To be demonstrated. The pressing body 6 is cut off on the lower surface side, and side walls 17a and 17a are provided in the indoor / outdoor direction of the handrail 5b. Moreover, both side walls 17a and 17a are inclined in a square shape. Even in the state of FIG. 3A in which the raising and lowering bar 4 is raised, the handrail 5b is located in a space surrounded by the handrail pressing surface P of the pressing body 6 and the side walls 17a and 17a . Back and forth shake and flutter are suppressed. In the state of FIG. 3B in which the raising and lowering bar 4 is lowered, the handrail 5b is fitted in the deepest portion between the side walls 17a and 17a , and thereby the lower portion of the sliding door 1 is fixed to the handrail 5b. At this time, the upper portion of the handrail 5b may be sandwiched between the inclined surfaces 7a and 7a of the side walls 17a and 17a .
[0012]
The present invention is not limited to the embodiments described above. As shown in FIG. 4 , the pressing body 6 may be formed in a convex shape with respect to the groove-shaped rail 5. The form of the operation unit 3 may be a thumb turn type or a vertical slide type. By providing the operation unit on the vertical shaft, the operation unit can be provided at a height with good operability regardless of the installation height of the rail.
[0013]
【The invention's effect】
In the sliding door device according to the first aspect of the present invention , the handrail pressing surface of the pressing body is separated from the handrail in the state in which the raising / lowering rod of the free stopper is lifted. By having an inclined surface that inclines so that the distance between the two is wide, the handrail is located between both side walls, and the sliding door is movable along the longitudinal direction of the handrail while restricting the movement in the indoor and outdoor directions by the both side walls. As a result, swinging and fluttering of the sliding door in the indoor / outdoor direction can be suppressed. In addition, when the lifting rod is lowered and the stopper is applied, the handrail pressing surface of the pressing body presses the handrail downward, and the handrail is positioned between both side walls of the pressing body to move the sliding door in the indoor / outdoor direction. Because it regulates, the lower part of the sliding door is fixed stably.
[0014]
In the sliding door device according to the second aspect of the present invention, in the state where the raising / lowering rod of the free stopper is raised, the handrail pressing surface of the pressing body is separated from the handrail. The pressure body is located between the groove walls of the concave groove, and the sliding door is controlled in the longitudinal direction of the handrail while regulating the movement in the indoor and outdoor directions on both side walls. Accordingly, as in the case of the first aspect, the swinging and fluttering of the sliding door in the indoor / outdoor direction can be suppressed. In addition, when the raising and lowering bar is lowered and the stopper is activated, the handrail pressing surface is pressed against the groove bottom of the concave groove, and the pressing body is positioned in the concave groove to restrict the indoor / outdoor movement of the sliding door. The lower part of the sliding door is fixed stably.
[0015]
Furthermore, it is possible to provide a sliding door that can be used for a variety of functions including blindfolds on the verandas of apartments and condominiums. Moreover, the sliding door has a free stopper that can be pressed and separated from the handrail by a simple operation. Thus, the sliding door can be easily and reliably fixed at an arbitrary position on the handrail, and the handrail is not damaged.
