Description of the Related Art In a top-hanging sliding door in which a sliding door is hung on a rail via a runner so that the sliding door can run freely, a runner body fixed to the sliding door is provided with wheels for rolling the rail. The sliding door is mounted on the rail in a substantially U-shape by being attached to the left and right corners of the sliding door so that the sliding door can be freely run on the rail.

が跳ね返ることがある。[0003] In the above-mentioned sliding door of the upper suspension type, since the runner main body has wheels, the sliding door can be moved smoothly and lightly. However, when the sliding door is closed vigorously, it hits the vertical frame at the closed position. Sliding doors may bounce off due to recoil.

Conventionally, for example, a spring member (leaf spring) is bent in a substantially elliptical shape so as to be in contact with the runner body, protrudes from a position short of the closing position of the sliding door to the closing position, and is disposed in the rail. A braking device having a structure in which a brake is applied to a sliding door by pressing a wheel of a runner body against a rail by using a restoring force (hereinafter referred to as a pressing force) of the spring member at that time in contact with a spring member. Has been

くてはならないという問題があった。However, in the above-mentioned braking device, a braking force is applied to the sliding door by utilizing a pressing force of the spring member to return elastically when the spring member abuts on the runner body and deforms. Therefore, as long as the runner body is in contact with the spring member, a braking force is exerted on the sliding door by the pressing force of the spring member. For this reason, it is said that the sliding door must be opened with a corresponding force against the braking force from the closed position to the position where the runner body does not contact the spring member during the opening operation of the sliding door, that is, in the arrangement band of the spring member. There was a problem.

ることができないという問題があった。Further, in the above-described braking device, the runner main body abuts and deforms the spring member when the sliding door is closed, so that the impact force on the spring member and the amount of deformation of the spring member are extremely large. For this reason, there has been a problem that the elasticity of the spring member is easily reduced at an early stage, and a constant braking force cannot be applied to the sliding door for a long period of time.

ね返りを確実に防止することができた。Therefore, in view of the problem of the braking device, the applicant of the present invention has a rail formed in a substantially U-shape and a wheel for rolling the rail, which is fixed to a sliding door and fixed to the sliding door. , A braking member protruding out of contact with the runner body and disposed in the rail from a position short of the closing position of the door to a closing position, and a spring member bent and formed to rotate around the runner body. An operating member movably provided with an operating piece that is displaced by coming into contact with a braking applying member, and a braking member provided on the operating member and applying a braking force by pressing against a rail or a wheel by the displacement of the operating piece. An invention characterized by this is disclosed (Japanese Patent Application Laid-Open No. 9-72154). With such a configuration, it is possible to reduce the impact force at the time of hitting the vertical frame at the closed position of the door at the time of the door closing operation, and it is possible to reliably prevent the door from rebounding.

適正な制動力を簡易に付与することができなかった。[0008] By the way, there are many types of doors, and weights vary. For example, if the braking force is weak for a heavy door, the door will not be braked enough to prevent the door from bouncing. Conversely, if the braking force is strong for a light door, the door will be braked. Is too strong to close the door smoothly and lightly. Therefore, it is necessary to apply an appropriate braking force according to the weight of the door. However, the conventional braking device cannot easily provide an appropriate braking force according to, for example, the weight of the door.

It is to provide a door braking device which can be prevented.

The door braking device according to claim 1 is, for example, a rail 1 formed in a substantially U-shape as shown in the following illustrated embodiments.
A runner body 10 having wheels 8 and 9 for rolling the rail 1 and being attached to a door and running in the rail 1;
A braking member 23 protruding out of contact with the runner body 10 and disposed in the rail 1 from just before the closed position of the door; and a braking member 23 provided movably in the rail 1 along with the runner body 10 and Braking member 23

れる。According to the door braking device of the first aspect, when the braking force of the door is too strong, the adjusting member 21 shortens the length of protrusion of the contact portion 43 of the operating member 40. Then
When the contact portion 43 comes into contact with the braking applying member 23, the displacement of the operating member 40 becomes small, and the pressing force of the braking member 42 against the rail 1 becomes small, so that the braking force becomes weak. On the other hand, when the braking force of the door is too weak, the length of protrusion of the contact portion 43 of the operating member 40 is shortened by the adjusting member 21. Then, when the contact portion 43 comes into contact with the braking applying member 23, the displacement of the operating member 40 increases, and the pressing force of the braking member 42 against the rail 1 increases, thereby increasing the braking force. When traveling through the door, the operating member 40 is attached to the braking applying member 23 just before the closed position of the door.
When the abutting portion 43 abuts, the abutting portion 43 retreats to the lower surface of the braking applying member 23 and is displaced, and the operating member 40 rotates about the fulcrum, and the braking member 42 comes into pressure contact with the rail 1, A braking force is applied to the runner body 10. As a result, the traveling speed of the runner body 10 is appropriately reduced, and the impact force when the runner body 10 hits the vertical frame at the closed position of the door is reduced.

る。According to the door braking device of the present invention, when the braking force of the door is too strong, the adjusting member reduces the length of protrusion of the contact portion of the operating member. Then, when the contact portion contacts the braking member, the displacement of the operating member is reduced,
The pressing force of the braking member against the rail decreases, and the braking force decreases. On the other hand, when the braking force of the door is too weak, the length of protrusion of the contact portion of the operating member is increased by the adjusting member. Then, when the contact portion contacts the braking applying member, the displacement of the operating member increases, and the pressing force of the braking member against the rail increases, thereby increasing the braking force. Then, when the abutting portion of the operating member abuts on the braking applying member before the door closing position when traveling through the door, the abutting portion is retracted to the lower surface of the braking applying member and displaced, and the operating member defines the fulcrum. The brake member rotates to the center and the brake member presses against the rail to apply a braking force to the runner body. As a result, the traveling speed of the runner body is appropriately reduced, and the impact force when the runner body hits the vertical frame at the closed position of the door is reduced.
