(Field of Industrial Application) This invention relates to a closing braking device for a sliding door, which is used for entrance sliding doors and other sliding doors for entrances and exits, and is suitable for mitigating the impact when the sliding door is closed. (Prior Art) Conventionally, wires connected at one end to the vertical frame of a sliding door frame and connected to a weight at the other end are pulled to a rotating body attached to the top of the sliding door via a horizontal shaft with a portion protruding. The sliding door has a structure in which the sliding door is automatically moved in the closing direction by the weight of the weight. In a sliding door with such a structure, the sliding door is manually moved in the opening direction, and when it is closed, it is automatically moved in the closing direction by the weight of the weight, but when the sliding door is closed, the inertia of the movement is also applied. Since it hit the vertical frame of the sliding door frame with a shocking impact, some kind of countermeasure had to be taken. Therefore. In conventional sliding doors, as a structure to reduce the impact when the sliding door frame is closed, an air cylinder is attached to the upper frame of the sliding door frame, whose piston tip is pressed and braked by a bracket installed at the upper end of the sliding door when the sliding door is in the closed position. (1986)
-111273 Publication), and a structure in which an air cylinder whose piston tip is pressed by a bracket fixed to the wires in the closed position of the sliding door to perform braking is attached to the vertical frame of the sliding door frame (Utility Model Publication No. 62-32178). Publications), and structures in which an oil cylinder or air cylinder is installed on the door stop surface of the vertical frame of the sliding door frame, and the sliding door is received by a piston (Utility Model Application No. 59-2875, Utility Model Application No. 59-150866) Public bulletin) etc. were published. (Problem that the invention aims to solve) However, in the conventional sliding door closing braking device, an air cylinder or an oil cylinder was used as a structure to reduce the impact when the sliding door was closed, so This causes changes in the movement of the piston, making it difficult to adjust the degree of braking, and when using an intake/exhaust type air cylinder, the influence of dust and condensation is large, and intake/exhaust noise may be generated. Due to its large size, it may be difficult to fit it within the specified dimensions (inside the upper frame of the sliding door frame, vertical frame, etc.), and it is likely to be expensive. A number of problems arose. (Purpose of the invention) This invention was devised in view of the conventional problems mentioned above. It is possible to brake the sliding door stably without being affected by cold and heat, and it has a simple structure and size. The object of the present invention is to provide a closing braking device for a sliding door that has fewer problems with fitting and can be made at a low cost.

(Means for solving the problem) This invention is based on the idea that wires, one end of which is connected to the upper frame or vertical frame of the sliding door frame, and a weight connected to the other end, are connected to the top of the sliding door via a horizontal shaft. The sliding door has a structure in which the sliding door is hooked onto a rotating body such as an attached jeep or pulley and automatically moves in the closing direction by the weight of the weight, and the rotating body has a large diameter part and a small diameter part, and the wires is hooked on the small diameter part, and the upper frame of the sliding door frame is provided with a braking body that comes into contact with the rotating body at the closed position of the sliding door (of course, it may also include a position near the closed position). In one embodiment, the braking body has a downward pressing force using a spring, a weight, etc., and the pressing force can be varied as necessary to provide control. It is characterized by being able to adjust the power. (Embodiment) FIGS. 1 to 5 are diagrams showing an embodiment of this invention, and a closing braking device for a sliding door according to this invention is installed in a sliding door having the schematic structure shown in FIG. 5. The sliding door 1 shown in FIG. 5 is capable of moving in the left-right direction within a sliding door frame 6 composed of an upper frame 2, left and right vertical frames 3 and 4, and a lower frame 5. This sliding door 1 has an upper stile 11, left and right vertical stile 12, 1
3 and a lower stile 14, and has a structure in which a handhold portion 15 and the like are provided. At the upper end of the left vertical stile (joining stile) 12 of this sliding door 1, there is a rotating body 16, which can also be called a sheave or a pulley, as shown in FIGS. 1 to 3, and a rotating body bracket 17, 17 and a horizontal shaft. The rotating body 16 has a large diameter part 16a and a small diameter part 16b, and has one end connected to the vertical frame 4 of the sliding door frame 6 at a connection point 19a. Wires 19 connected to a weight 20 at the connection point 19b on the other end side are hooked onto the small diameter portion 16b of the rotating body 16, the weight 20 is disposed inside the vertical frame 12, and the sliding door 1 is closed as shown in FIG. When manually operating the door to the left to open the doorway, the weight 20 rises inside the vertical stile 12, and when the manual operation is completed, the weight 20 descends due to its own weight and at the same time opens the sliding door 1 to the first position. The sliding door 1 can be automatically closed by automatically moving in the right direction in the figure. In this invention, in order to prevent the sliding door 1 from strongly colliding with the vertical stile 4 of the sliding door frame 6 when the sliding door 1 is closed, the running of the sliding door 1 is braked. That is, the braking of the sliding door 1 is performed by a braking piece 21a that contacts the large diameter portion 16a of the rotating body 16 at the closed position of the sliding door 1 (a position near the closing may be included), and this braking piece 21a. This is done by a brake body 21 consisting of a brake piece holder 21b fixedly held by screws 22, 22 with its tapered surface 21c side located on the left side in FIG. One end of the sliding door in the closing direction (the right end in FIG. 1) is cantilevered to a support piece 24 fixed to the upper frame 2 with a screw 23, and the other end of the brake body 21 is secured with a screw 25. A long hole 2 fixed and formed in the brake piece holder 21b
A weight 26 whose movement can be adjusted within a range of 1d is provided, and a curved slope portion is provided on the bottom surface of the other end of the brake body 21 to hold the sliding door 1 in an open state regardless of the weight of the weight 20. A sliding door holder 27 having a sliding door holder 27a is provided, and a sliding member locking piece 28 is fixed to the upper frame 2 with screws 29 to prevent the other end of the brake member 21 from lowering too far downward. There is. In the sliding door 1 having such a configuration, when the sliding door 1 is opened by manual operation, the weight 20 rises within the vertical frame 12 by being pulled through the wires 19 and the rotating body 16, and when the sliding door 1 is opened. In the fully open state, the rotating body 16 is attached to the sliding door holder 27.
By being located on the inclined part 27a of the sliding door 1
It stops at this position even though a force in the closing direction is applied due to the weight of the weight 20. Next, when closing the sliding door 1, the braking body 21 uses its right end as a fulcrum and its left end rises slightly,
When the rotating body 16 passes the sliding door holder 27,
The left end side of the brake body 21 is lowered, and the left end side is locked by the sliding body locking piece 28, and the sliding door 1 automatically moves rightward in FIG. 1 due to the weight of the weight 20. Next, when the sliding door 1 comes to a position near its closing, the large diameter portion 16a of the rotating body 16 engages the brake piece 21a.
The large diameter portion 16a of the rotating body 16 contacts the tapered surface 21c of the brake piece 21a along the flat surface of the brake piece 21a as the brake body 21 rises slightly using its right end side as a fulcrum. That is, since the wires 19 are hooked on the small diameter portion 16b of the rotating body 16, when the rotating body 16 rotates by a certain angle, the arc length of the large diameter portion 16a and the arc length of the small diameter portion 16b are different. For example, a slip occurs between the large diameter portion 16a of the rotating body 16 and the brake piece 21a, and this slip serves as a braking action when the sliding door 1 moves, and the sliding door 1 is in a braked state. It gently hits the vertical frame 4 and stops. In this embodiment, when the screw 25 is loosened and the weight 26 is moved to the left in FIG. When moving to the right in Figure 1, the braking force decreases. Further, in this embodiment, in order to obtain the braking force, a downward pressing force is applied to the brake body 21 by the weight 26, but it is not possible to use an elastic body such as a coil spring or a leaf spring. Good too. Furthermore, although this embodiment shows a case in which one end of the wires 19 is connected to the vertical frame 4 at the connection point 19a, it may be connected to the upper frame 2. Furthermore, although the weight 20 was configured to move up and down inside the left side vertical frame 12 which is a gathering frame, the weight 20 was moved up and down inside the right side vertical frame 13.
The rotary body 16 may be provided at the upper end, and the weight 20 may also be moved up and down within the right-hand stile 13. In this case, it goes without saying that the braking body 21 must also be moved to the right side in Figure 1. Nor. Furthermore, the rotating body 16 may have a structure including a large diameter portion 16a and a small diameter portion 16b as shown in FIG.
