[Industrial applications]
The present invention relates to a sliding suspension rail structure in a suspension door provided at an entrance or a passage of a building.
[0002]
2. Prior Art and Problems to be Solved by the Invention
Generally, in this type of suspension door, as shown in FIG. 2, there are inward guide grooves 4a, 4b above and below the outer slide rail 4, and above and below the inside slide rail 5 where the door 1 is supported. A plurality of balls 6 supported by a retainer 7 are suspended between the outwardly directed guide grooves 5a and 5b using a sliding suspension rail 2 rotatably interposed therebetween. There is an arrangement in which the opening and closing movement is performed more smoothly than that of the suspension roller type.
[0003]
By the way, in such a slide type suspension rail 2, when the inner slide rail 5 moves, the retainer 7 theoretically moves by 移動 of the movement stroke with respect to the outer slide rail 4, and furthermore, the retainer 7 moves. Is set such that the inner slide rail moves by の of the moving stroke. However, deviation occurs in the ideal relative movement of the above-mentioned one-half due to a biased load acting on the inner slide rail 5 and the retainer 7 and a difference in rotation resistance between the balls 6 and the inner or outer slide rails 4 or 5. In such a case, the inner slide rail 5 comes off from the retainer 7, and it is necessary to take measures to prevent this.
[0004]
Conventionally, as shown in FIGS. 7 and 8, locking portions 7 f are formed at both ends of the retainer 7, and locking receiving portions 5 f are formed at both ends of the inner slide rail 5. When the end portion moves to the end position of the retainer 7, the relative movement of the inner slide rail 5 with respect to the retainer 7 is restricted by the locking receiving portion 5f being locked to the locking portion 7f. 5 from the retainer 7. However, in this case, if the movement of the inner slide rail 5 is restricted at a position before the door body 1 is fully closed (or fully opened) as shown in FIG. 9, the door body 1 is not fully closed but is half open. There is a problem that the door 1 must be forcibly closed in order to stop in the state and correct it.

[Means for Solving the Problems]
SUMMARY OF THE INVENTION The present invention has been made in view of the above-described circumstances, and has been created with the object of providing a slide-type suspension rail structure in a suspension door that can eliminate these disadvantages, and is integrally attached to a skeleton side. A ball supported by a retainer is rotatably interposed between an inward guide groove above and below the outer slide rail and an outward guide groove above and below the inner slide rail where the door body is supported. In the above-mentioned hanging door, the door body is movably opened and closed by using a sliding type hanging rail, and the inner slide rail is disengaged from the inner slide rail by being locked to the locking portions provided at both ends of the retainer. Upon providing the lock receiving portion for the stopper, locking receiving portion is provided by biasing the rail length direction closer to the center than the rail end portion of the inner slide rail, a retainer Movement of the inner slide rail which is sliding suspension rail structure in Tsuto, characterized in that the set to allow extra travel beyond the retainer end position.
[0006]
According to the present invention, with this configuration, it is possible to absorb a deviation caused by a relative movement between the inner slide rail and the retainer with respect to the outer slide rail.
[0007]
【Example】
Next, an embodiment of the present invention will be described with reference to the drawings. In the drawings, reference numeral 1 denotes a door constituting a suspension door provided at an entrance or a passage of a building, and the door 1 is suspended by a slide-type suspension rail 2 described later provided at an upper portion of an opening. In such a state, it is provided so as to be movable left and right between a closed position for closing the opening and a storage position for storing the opening in the door pocket 3 provided inside the room on one side of the opening. Have been.
[0008]
The slide type suspension rail 2 is supported by a skeleton, and has an outer slide rail 4 in which vertically inward guide grooves 4a and 4b are formed, and a door body 1 is supported and vertically lower guide grooves 5a and 5b. Is formed, a plurality of balls 6 rotatably interposed between the opposing guide grooves 4a, 5a and 4b, 5b, and the balls 6 are arranged at predetermined intervals. And a retainer 7 that supports it in a series. Then, as the inner slide rail 5 moves, the ball 6 rolls between the inner slide rail 4 and the outer slide rail 5, and the retainer 7 moves by a half of a predetermined stroke with respect to the outer slide rail 4. The inner slide rail 5 moves the retainer 7 at the same time as the movement of the moving retainer 7 and moves by a half of a predetermined stroke, so that the inner slide rail 5 moves relative to the outer slide rail 4 by a predetermined stroke. Is set to
[0009]
By the way, the outer slide rail 4 is attached to the skeleton side by fastening the groove bottom side 4c of the outer slide rail 4 to the skeleton frame 8 integrally supported by the skeleton via screws 8a. The retainer 7 provided in the recessed groove portion of the outer slide rail 4 so as to be fitted inside is formed with a protruding ridge 7a which is located at the center in the width direction and bulges to avoid the head of the screw 8a. The upper side 7b located at the left and right ends of the retainer projection 7a is formed with a locking portion 7c cut and raised upward.
[0010]
On the other hand, on the upper surface of the inner slide rail 5 opposed to the retainer 7, a lock receiving portion 5c is formed so as to be locked to the retainer locking portion 7c, whereby the inner slide rail 5 is retained. The locking receiving portion 5c is formed at a position deviated toward the center by a dimension A in the rail length direction from the position of both ends of the inner slide rail 5 in the rail length direction. Accordingly, the inner slide rail 5 is set so that the movement of the inner slide rail 5 with respect to the retainer 7 can be moved by an extra dimension A beyond the end position of the retainer 7.
Also, both left and right edges of the outer slide rail 4 are cut and raised toward the inner slide rail 5 to form a stopper piece 4d, whereby the retainer 7 and the inner slide rail 5 come off from the outer slide rail 4. It is configured to stop.
[0011]
In the drawing, reference numeral 9 denotes a connection fitting for connecting the door body 1 to the inner slide rail 5, and the connection fitting 9 is screwed to a widthwise central portion of the inner slide rail 5 by a screw 9a. . Further, 10 is a self-closing device for the door body 1, 11 is a shock absorber for shock absorbing when the door body 1 is fully closed, and 12 and 13 are holding devices for holding the fully opened door body 1. These are optional. Can be attached arbitrarily, and details thereof are omitted here.
[0012]
In the embodiment of the present invention configured as described above, the door body 1 suspended on the slide-type suspension rail 2 has the ball 6 between the outer slide rail 4 and the inner slide rail 5 as described above. The rolling allows the opening and closing to be performed lightly, but in this case, the locking receiving portion 5c of the inner slide rail 5 that locks to the locking portion 7c formed at the end of the retainer 7 is not used. Since the inner slide rail 5 is formed closer to the center by the dimension A than the end position, the inner slide rail 5 is allowed to move further by the dimension A beyond the end position of the retainer 7. As a result, there is a biased load acting on the door body 1 and the like, and the relative movement between the outer slide rail 4, the retainer 7 and the inner slide rail 5 shifts, and the door body 1 is completely closed or fully opened. When the inner slide rail 5 moves to the end position of the retainer 7 at the previous position, the door body 1 is in a movable state with play only in the dimension A, and the conventional lock receiving portion 5c is moved. The door body 1 is prevented from being half-opened as in the case where the inner slide rail 5 is provided at the end position and the movement of the inner slide rail 5 is restricted at the end position of the retainer 7.
[0013]
As described above, the slide type suspension rail 2 according to the present invention is formed by biasing the retainer locking portion 7c toward the center in the rail length direction while the inner slide rail 5 is prevented from coming off the retainer 7. By doing so, the gap between the retainer 7 and the inner slide rail 5 can be absorbed by the dimension A. In this case, the lock receiving portion 5c and the lock portion 7c are connected to the rail. It is provided so as to be deviated upward from the central portion in the width direction, so that the end of the screw 9 a for fastening the fitting 9 provided in the central portion in the width direction of the inner slide rail 5 is positioned at the center of the retainer 7 in the rail length direction. The movement of the inner slide rail 5 is not impaired by hitting the locking portion 7c formed as described above.
[0014]
When the slide type suspension rail 2 according to the present invention is mounted and set on a frame, as shown in FIG. 6, the set position of the retainer 7 with respect to the outer slide rail 4 is shorter than the theoretical set position. The arrangement may be such that the displacement in the direction in which the retainer 7 contacts the stopper piece 4d of the outer guide rail 4 in a stage before the door body 1 is fully closed or in the front open state. The length of the retainer 7 can be absorbed by an amount set to be short, and the length of the locking receiving portion 5c of the inner slide rail 5 biased toward the center and the arrangement position of the retainer 7 can be adjusted. Deviation can be absorbed.
[0015]
[Effects]
In short, since the present invention is configured as described above, the inner slide rail of the slide type suspension rail has a locking receiving portion for locking to the locking portion formed at the end of the retainer in the rail length direction. Since it is formed closer to the center, it can move beyond the end position of the retainer, and as a result, if there is a relative displacement between the inner slide rail and the retainer, a play that can absorb the displacement. As a result, light opening and closing can be maintained.
