Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door device in which a rail for suspending and guiding a door is inclined, and the door is automatically (naturally) mainly closed and moved by the inclination of the rail.

[0002]

2. Description of the Related Art In the prior art, an inclined rail for suspending and guiding a door to naturally move the door is a single rail extending from the door pocket to the entire length of the doorway.

[0003]

The above prior art has the following problems. (1) In order for the door to slide from the initial movement, the rail must be provided with an inclination angle necessary for the initial movement to occur. As the door slides, the long rail is accelerated more and more. It was of a structure. For this reason, when the door is closed, the speeded-up door will strongly collide with the doorway wall and make a loud noise or bounce,
It had a problem of hitting people strongly. That means that the opening time of the door is shortened, and there is also a problem that it is difficult for a person with slow body movement to use the door. (2) Since it is difficult to make fine adjustments such as relaxing the acceleration of the movement at an appropriate location, a speed mitigation / cancellation device such as an air damper should be used when one third is left when the door is closed. However, this has resulted in an increase in the cost of the door device. (3) In the case of an inclined rail, a height difference H occurs between the ends of the rail. However, in the case of the conventional technique, the height difference H becomes large because the rail is long, and as a result, the upper and lower use range becomes large, so the upper frame. The vertical width of the upper frame becomes larger, the upper frame becomes larger,
There was a problem that the cost was increased. (4) In the closed state of the door, the gap between the floor surface and the bottom of the door widens toward the door pocket side, giving an unnatural impression to the viewer. In order to compensate for this, the bottom of the door is inclined, the rail is bent as disclosed in Japanese Utility Model Application Laid-Open No. 5-38250, and an auxiliary rail is provided on the upper part of the door side and the auxiliary rail is mounted on the auxiliary rail when the door is closed. Some of the hanging wheels are attached to the door to realize a brake before closing, lightness when opened by hand, a horizontal state when closed, and the like, but these increase the cost of the apparatus. Further, the configuration in which the auxiliary rail is provided has a problem that the upper frame is further enlarged. (5) The rail is long and has a problem that the rail is bent by the weight of the door because the whole weight of the door to be suspended is supported by one rail. To solve this problem, the strength of the rail is increased. In addition, it is necessary to devise measures such as increasing the number of fixing points, resulting in an increase in cost. (6) In hospitals and the like, the doorway is enlarged in order to allow wheelchairs, beds, stretchers and the like to pass through. For this reason, the rails and the upper frame become very long, and there is a problem that transportation costs and other costs are high. In addition, when two rails are abutted against each other, a step or a dent is generated at the abutting portion of the rails, which causes a problem that smooth movement of the door is impaired. In addition, the problem of rail deflection has become more serious. (7) Due to the inclination of the rails, there is a problem that the resistance is not small when opened by hand, and it is difficult for a weak person to open.

It is a front view which shows the inclination state of. FIG. 15 is a front view showing an inclined state of a conventional rail. In FIG. 12, a door device 80 includes a door frame 81 provided at an opening of a building (not shown). The doorway frame 81 is formed in a gate shape by left and right vertical frame portions 82 and 83 and an upper frame 84. As shown in FIG. 13, the front surface of the upper frame 84 can be opened and closed by a hinge 85. This allows
Inspection of members provided in the upper frame 84, for example, rails, movable members, and the like, which will be described later, can be easily performed. In the upper frame 84, a rail 86 is arranged and fixed. The rail 86 includes a doorway side rail 90 and a door pocket side rail 89. The doorway side rail 90 and the door pocket side rail 89 have almost half the length of the conventional rail, and are arranged with their longitudinal directions facing left and right. Moreover, the doorway side rail 90 and the door pocket side rail 89 are
It is inclined so as to form a downward slope toward the open position side (the left side in FIG. 12). The inclination angles of the doorway side rail 90 and the door pocket side rail 89 are the same as each other, but may be slightly different from each other. Further, the doorway-side rail 90 is arranged at the same height. In other words, the ends on the open position side of the doorway side rail 90 and the door pocket side rail 89,
And the ends on the closed position side have the same height. The doorway side rail 90 and the door pocket side rail 89 may be arranged at slightly different heights.

On the doorway rail 90 and the doorbag side rail 89, a doorway side movable member 92 and a doorbag side movable member 91, each of which is comprised of a hanging door roller, are provided so as to freely roll. Movable members 92 and 9
1 is connected to upper left and right ends of a door 95 via connecting members 93 and 94, respectively. Thereby, the door 95 is supported by the doorway side rail 90 and the door pocket side rail 89 so as to be movable in the left-right direction, and the door 95 moves between the open position shown by the imaginary line in FIG. 14 and the closed position shown by practice. It is possible. As shown in FIGS. 12 and 13, a guide wheel 96 is provided on the floor F at the opening of the building.
When the guide wheel 96 rolls in the guide groove 97 formed on the lower surface of the door 95, the lower end of the door 95 is guided when moving in the left-right direction.

In the door device 80, the doorway side rail 9
0 and the door pocket side rail 89 are inclined so as to form a downward slope from the open position side to the closed position side. Therefore, the door 95 located at the open position automatically moves to the closed position by its own weight. Can be. In addition, since the length of the doorway side rail 90 and the door pocket side rail 89 is substantially half of the length of the rail 100 of the related art (see FIG. 15) integrally formed as a whole, the inclination angles thereof are made the same. In this case, the height difference between the doorway side rail 90 and the door pocket side rail 89 is about half of the height difference H of the conventional rail. Of course, the height difference of the entire rail 81 is also 1 / 2H. Therefore, the width of the upper frame 84 in the vertical direction can be reduced.

The present invention is not limited to the present embodiment, but can be changed as appropriate. For example, in the eighth embodiment, a hanging door wheel is used as a movable member, but a slider having a large number of circulating steel balls may be used instead.

Ninth Embodiment FIG. 16 is a front view showing a ninth embodiment of the present invention, and FIG. 17 is a partially enlarged view showing a main part of the ninth embodiment. The door device 110 separates the doorway side of the door device side rail 6 and the door pocket side rail 7 of the door device 1 into appropriate lengths, and
, Doorway side rail 113 and door pocket side rail 114
It is what it was. Main rail 111 and inclination change rail 1
An adjusting unit 115 having the same configuration as the position adjusting unit 11 for adjusting the vertical position is provided at both ends of the unit 12. After the assembly is completed, fine adjustment is performed on site. Thereby, the inclination of this rail is steep (for example, 5 degrees as shown in the figure).
This makes it possible to speed up the initial movement operation, make the inclination change rail substantially horizontal gradient (for example, twice as shown in the figure), reduce the speed just before closing, and obtain a gentle closing operation.

[0025]

Since the present invention has the above-described configuration, the following effects can be obtained. <Effect of the Invention According to Claim 1> A doorway side rail and a door pocket side rail are provided with a downward slope on the doorway side (door closing side), and a doorway side movable member that travels on the doorway rail at the downside end of the door. Since the door-bag-side movable member that runs on the door-bag-side rail is provided at the end of the climbing side, the following effects can be obtained. (1) Since the inclination angle of the rail for initially moving the door naturally from the open state may be substantially the same as that of the conventional single rail, the length of the rail is approximately half that of the conventional technology. The height difference H can be reduced to approximately half of the conventional height. That is, the space saving of the upper frame and the reduction in size and weight of the device are realized. (2) Since the running inclination is reduced as the vehicle descends, the door can be moved slowly and gently with greatly reduced acceleration. It realizes a longer door closing time, making the door device easier to pass. In addition, when the door is opened by hand from the closed state, the running inclination of the door is horizontal or nearly horizontal, and the running uphill is gentle at first. However, a door device that can easily open the door is realized. (3) Since a structure that supports half the weight of the door with a rail having approximately half the length of the conventional one is realized, the strength of the rail is substantially improved, and the rail may be bent. Instead, it allows the use of cheaper rails. In particular, it realizes a door device with a wide doorway at low cost. (4) The downside ends of the doorway side rail and the door pocket side rail are configured to be positioned on the horizontal line, so that the posture of the closed door is adjusted to be horizontal with the floor surface. can do. This realizes a door device that does not look strange. (5) Low cost is realized from the above.

<Effect of the Invention According to Claim 2> In addition to the effect of the invention described in claim 1, in addition to the effect that the door is vertical to the door frame and horizontal to the floor when the door is closed. Play.

<Effect of the Invention According to Claim 3> In addition to the effect of the invention described in claim 1 or 2, it is possible to adjust the inclination angle of each rail, so that after the device is mounted, the working state etc. Can be obtained.

<Effect of the Invention According to Claim 4>
In addition to the effects of the invention described in 2 or 3, in addition, for example, the door pocket side rail is inclined toward the door door side, and the door door side rail is inclined in the same manner, in a horizontal state, or slightly inclined toward the door pocket side. can do. As a result, the sliding angle of the door is initially set to be steeper and accelerated, the sliding slope is set to be gradual as it moves, so that the speed decreases, and finally the door is closed slowly and gently to complete the movement. Moving at a constant slow speed,
And the like can be freely realized. Fine adjustment can be arbitrarily performed at each site in accordance with the implementation status of the site, such as a standing state, and optimum sliding movement can be realized according to the standing, the habit of the device, and the like. It can be done even after the enforcement process.

<Effect of the invention described in claim 5> In addition to the effects of the invention described in claim 3 or 4, the meshing portion on the rail side and the meshing portion on the upper frame side are directly fixed with a meshing bolt, or an adapter. The rails are fixed by bolts, so loosening the bolts, shifting the meshing part up and down, and tightening and fixing the bolts makes it easy to adjust, and secures the rail firmly and reliably by meshing. Is achieved. Further, there is an effect that the meshing portion on the upper frame side also serves as a scale line.

<Effect of Invention of Claim 6> Even with such a configuration, the same effect as that of the invention of claim 5 can be obtained.

<Effect of the Invention According to Claim 7>
The invention described in Item 6 has one feature in that it is not necessary to connect two rails. Therefore, in addition to the effects of the inventions according to the first to sixth aspects, the invention according to the seventh aspect has a structure in which the upper frame is divided into two corresponding to the two rails and fixed by butt-fixing at the site. There is an effect that such a problem that the door travels unnaturally does not occur. In other words, even if a gap or deviation occurs, the traveling is not affected at all, so that a simple mounting operation such as rough butting and fixing is sufficient. Because the half upper frame is shorter in weight and length, it reduces transportation and other expenses and facilitates installation work, and is particularly suitable for wide doorway door devices. Things.

<Effect of the Invention of Claim 8>
In addition to the effects of the invention described in 2, 3, 4, 5, 6, or 7,
By adjusting the inclination angle of the inclination change rail to, for example, a small angle, the traveling speed can be reduced and the door can be closed at a low speed just before the closing of the door is completed. As a result, it is possible to adjust a more subtle traveling on the spot.
