Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a structure of a sliding door provided at a garage or other entrance / exit.

[Prior Art] As shown in FIG. 6, a conventional sliding door 1 is provided with a traveling wheel 2 at a lower portion of the sliding door 1, and the wheel 2 is rotatably mounted on a guide rail 8 laid on a ground 7. Then, by rolling the wheel 2 along the guide rail 8, the sliding door 1 is reciprocally opened and closed.

[Problems to be Solved by the Invention] In the above-mentioned conventional example, however, there is a gap 25 between the guide rail 8 and the lower surface of the sliding door 1 as shown in FIG. At the same time, there is a problem that a foot or the like is caught in the gap 25 between the lower end of the sliding door 1 in the moving direction and the guide rail 8. In particular, when the sliding door 1 is moved electrically, it may be dangerous because the obstacle such as a foot may be driven without noticing that it is on the guide rail 8.

The present invention has been made in view of the above-mentioned points, and the object of the present invention is to prevent a foot or the like from being caught between the rail and the lower end of the sliding door in the moving direction. It is in providing a sliding door structure.

[Means for Solving the Problems] In order to achieve the above object, the structure of the sliding door of the present invention is such that a traveling wheel 2 is provided below the sliding door 1 and
Is rotatably mounted on a guide rail 8 laid on the ground 7, and the maximum width of the sliding door 1 from the lower ends of both ends in the reciprocating direction is approximately equal to the thickness of the sliding door 1, and a pinching prevention member. The structure is such that 24 is projected above the guide rail 8 so as to be close to the guide rail 8.

[Operation] When the sliding door 1 is moved, even if there is an obstacle such as a foot on the guide rail 8, the pinch prevention member 24 removes the obstacle and the lower end of the sliding door 1 in the moving direction and the guide rail 8 are removed. It is possible to prevent an obstacle from being caught between and.

[Embodiment] In the present embodiment, an embodiment of the gate 1a will be described as an example of the sliding door 1. A guide rail 8 is laid on the ground 7 where the gate 1a is attached so that it can be opened and closed. Wheels 2 provided at the bottom of the gate 1a are rotatably mounted on the guide rail 8 and the gate 1a is reciprocated left and right. It can run freely. A pinch prevention member 24 is continuously attached and attached downward from the lower end portions of both ends of the gate 1a in the reciprocating direction. The pinch prevention member 24 has a substantially V-shaped horizontal cross section,
As shown in FIGS. 3 and 4, the maximum width is approximately equal to the thickness of the sliding door 1, and the pinching prevention member 24 is located above the guide rail 8 and the lower part is slanted. It inclines downward toward the outside and the tip is close to the guide rail 8. Alternatively, the pinch prevention member 24 is formed of a relatively flexible material such as soft synthetic resin or rubber so as not to be injured when an obstacle such as a foot is hit. A pillar 9 is erected on one end side of the guide rail 8 so as to be a door stop when the gate 1a is closed. The other end of the guide rail 8 and the guide rail 8
A column 10 is erected at a position lateral to the guide rail 8 at an intermediate portion in the longitudinal direction, and a bracket 11 is attached to an upper end of the column 10 so as to extend laterally. A pair of guide rollers 12 are attached to the bracket 11, and the pair of guide rollers 12 sandwich the upper end of the gate 1a to guide the gate 1a movably. Fixed plates 14 are attached to lower portions of the vertical frames 13 at both ends of the gate 1a, and a chain 3 is installed between the fixed plates 14 at both ends. The chain 3 is covered with a chain cover 15 having a U-shaped cross section over the entire length. A drive device A is arranged near the pillar 10 located in the middle of the guide rail 8 in the longitudinal direction so as to face the pillar 10 via the guide rail 8. The drive unit A is internally provided with a motor 4 and a speed reducer 23, and the output of the motor 4 drives the speed reducer 23 via the transmission chain 16.
The output shaft 17 of the speed reducer 23 projects to the outside, and the drive sprocket 5 is mounted on the output shaft 17. The drive sprocket 5 is engaged with the chain 3. Tension sprockets 6 that idle are provided on both sides of the drive sprocket 5, and the drive sprocket 5 is attached to the chain 3
The tension sprocket 6 is engaged with the chain 3 so as to wind around. Further, the electric lock stopper 18 is projected from the drive unit A, and when the gate 1a is closed, the electromagnetic device
It can be locked at 19. Also drive device A
A control box 20, a radio control receiver 21, and a power supply device 22 are provided in the.

Then, when the motor 4 is driven, the drive sprocket 5 is rotationally driven, the chain 3 meshing with the drive sprocket 5 is driven by the drive sprocket 5, and a force is applied so that the gate 1a moves. When the motor 4 is driven in either forward or reverse rotation, the chain 3 is driven so as to move to the pillar 9 side, the wheels 2 roll, and the gate 1a is driven in the closing direction. Gate 1a as shown by the solid line in the figure
Is closed. Conversely, when the motor 4 is driven to rotate,
The chain 3 is driven so as to move in the direction away from the pillar 9, and is opened as shown in the imaginary line in FIG.

By the way, when the gate 1a reciprocates, if there is an obstacle such as a foot on the guide rail 8, the pinching prevention member 24 hits the obstacle such as the foot and shifts the foot to the side, and the obstacle is the gate. It is designed so as not to be pinched between the lower end of the end of 1a in the moving direction and the guide rail 8. In this case, the pinching prevention member 24 is formed of a relatively flexible material such as soft synthetic resin or rubber, so that the impact when it hits an obstacle is absorbed and the obstacle is not damaged. ing.

In the above embodiment, the example of the gate 1a is described as an example of the sliding door 1, but any other sliding door structure can be applied.

Further, although the example of the electric sliding door 1 has been described in the above embodiment, a manual sliding door 1 may be used.

[Effects of the Invention] As described above, the present invention provides a traveling wheel at the lower part of the sliding door and rotatably mounts the wheel on a guide rail laid on the ground. Since the maximum width is approximately equal to the thickness of the sliding door, the pinching prevention member is projected above the guide rail so as to be close to the guide rail. When there is an object, the pinch prevention member can prevent the obstacle from being caught between the sliding door and the guide rail, and even if there is an obstacle on the guide rail, it can be pinched. It is safe because it can be reliably removed by the prevention member.
