JP3040802U - Braking device with raised fiber for self-closing sliding door - Google Patents

Abstract

(57) 【Abstract】 PROBLEM TO BE SOLVED: To use a buffering action of an air cylinder to gradually stop when closing a self-closing sliding door in order to reduce the impact of the weight moving force of the door, however,
There is a drawback that energy for restoration is required in order to prepare the conditions of use for the next time each time. SOLUTION: Since a raised fiber is installed in a leaf spring that constitutes a braking mechanism of a self-closing sliding door, and a raising direction is set in a direction opposite to the direction in which the sliding door is closed, the self-closing sliding door is closed. As the raised parts facing each other successively hit different sliding parts along with the displacement of the sliding door, the moving force of the sliding door decreases and the sliding door stops gently. When the self-closing sliding door is opened, the sliding door roller moves in parallel to the smooth surface of the raised hair, so that the sliding door can be opened with a light force with little frictional resistance.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a structure in which a self-closing sliding door at an entrance is opened lightly, and when the self-closing sliding door is closed, the moving speed is gradually reduced to stop.

[0002]

[Means for solving the problem]

 In order to solve the above-mentioned object, in the device of the present invention, since the raised fiber is fixed to the leaf spring surface of the braking device shown in Document 1, the resistance of the raised fiber is continuous when the self-closing sliding door is closed. As the moving force of the sliding door is reduced, the moving speed of the sliding door gradually decreases and stops slowly. When the self-closing sliding door is opened, the door roller moves in the same direction as the brushed tip, and the door roller that moves on a smooth surface where the brushed hair moves can be easily moved.

[0003]

[Problems to be solved by the device]

 The conventional self-closing sliding door had a problem that a heavy door had to be opened and closed for daily access.

[0004]

[Prior art]

 In the conventional technology, when closing the self-closing sliding door, the movement of the sliding door weight is received by the air cylinder, and the air prepared and sealed in the cylinder is gradually released to counter the operating energy of the sliding door. A method was used in which the sliding door was stopped when the air pressure was reduced and the frontage was closed.

[0005]

[Embodiment]

 It was easier to open the heavy weight sliding door by using the “simple release mechanism and braking mechanism of the self-closing sliding door” in Reference 1, but this time when the self-closing sliding door is closed by adding brushed fiber to the braking mechanism. The sliding door C is in contact with each brushed tip that is added to the storage brake. As the sliding door moves, the next and other brushed tips continue to the C roller. Since it hits from the advancing direction, the total value of the frictional resistance due to the many raised parts gradually increases, and the sliding door slowly decelerates and then stops. Next, in the conventional device, since the closed air is released each time the self-closing sliding door is closed, a mechanism and force for simultaneously sucking air into the air cylinder must be added when opening the self-closing sliding door. However, the cylinder device is no longer necessary in the present invention.

【Example】

 An embodiment will be described with reference to the drawings. In the side view of FIG. 1, a state in which a self-closing sliding door 1 is closed is shown, and a rail 2 for sliding doors A and B doors is provided on a side wall 6 of a rammer. The leaf spring 3 is attached by the installation component 7 on the side wall 6, and the coil spring 5 is installed by the installation component 8 on the side wall on the door end side of the rammer. The raised fibers are fixed. When the self-closing sliding door 1 having the frontage is moved to the right on the slanted rail 2, the C door car comes into contact with the raised hair in the state shown in the side view of FIG. 2, and the raised hair tip is moved to the right. It exerts a braking effect on a moving C-door, that is, the resistance of each brushed tip is small, but a large number of brushed tips successively one after the other hits the C-door and moves to the right. As the kinetic force is reduced, the effect of the accumulated force braking of the leaf spring 3 and the coil panel 5 is added, and the C door car gradually decelerates and stops. When opening the self-closing sliding door 1 which has closed the frontage and is stopped, as shown in the side view of FIG. 2, the raised end of the raised fiber 4 is set to the left and the raised fiber has a smooth surface. Therefore, in addition to the condition that the C door wheel easily moves to the left in the direction of the bristle when it comes into contact with the surface of the raised hair, the effect of the accumulated force of the leaf spring 3 and the coil spring 5 is also added, so that You can open it with. In the side view of Fig. 3, when the self-closing sliding door 1 is looking over the frontage, the C door car has advanced to the front end of the frontage and has stopped gently. Since it is installed to the left, when the sliding door 1 is opened, the moving direction of the C door roller and the direction of the tips of the raised fibers are set in the same direction, so the wear resistance of both is extremely small. .

[0007]

[Effect of the invention]

 Since the present invention is configured as described above, it has the following effects. 1) It was necessary to adjust the moving force of the sliding door to close the self-closing sliding door, and an air cylinder was used. However, in order to open the front of the sliding door, the air cylinder was restored to the state before use. There was a drawback of consuming energy. 2) When napped fibers are installed in the storage brake according to the present invention, a large number of napped tips can contact the C-door, so that a large number of fine resistances brake the C-door and move in a predetermined direction. When the accumulated resistance reaches a certain value, the sliding door can be stopped gently. 3) Energy was required in the conventional device to open the closed sliding door, but in the present invention, there is no condition that restoration is required up to the condition before use. 4) The volume occupied by the structure is small, the height of the rammer is small, and the installation volume can be reduced.
