BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sliding door device that restricts the sliding door from returning by its reaction when it hits the vertical frame when the sliding door vigorously travels toward the vertical frame.

[0002]

In general, fittings such as shoji doors that do not use door wheels do not slide well, so they move vigorously to the vertical frame side, and even if they hit the vertical frame, they do not return in reaction. Although there is no sliding door with a door roller, it slides well, so when you drive the sliding door to the vertical frame side, it hits the vertical frame,
There was the inconvenience of returning to the half-open state by the reaction. Therefore, as in Japanese Utility Model Laid-Open No. 7-4753, it has been proposed to attach a sliding door braking member to the door roller running groove of the rail material, but the fixing means of the braking member to the rail material is provided with an attachment hole in the rail material. Since it is engaged with this mounting hole and is fixed using screws and nuts, there is a problem that the fixing position cannot be adjusted, and it is only partially fixed. There was also a problem that waving was caused by passage. Therefore, the present invention has been made in view of such problems of the prior art, and an object of the present invention is to provide a sliding door device that can easily fix a braking member and can limit the reaction of the sliding door. To provide.

BEST MODE FOR CARRYING OUT THE INVENTION Referring to the drawings, an embodiment of a sliding door device according to the present invention will be described.
The rail member 1 is provided with a braking member 5 made of a soft material and provided on the end side in the longitudinal direction of the door, and a sliding door P having a door roller R. With the engagement groove 3 located below, the door roller running groove 2 is provided with inclined running surfaces 2a and 2b facing upward on the upper sides of the facing groove side walls 3a and 3b so as to face each other. The groove 3 is formed wider than the running groove lower end width S, that is, the running groove lower end width S where the distance between the inclined running surfaces 2a and 2b is the narrowest, and the braking member 5 extends along the longitudinal direction of the rail material 1 on the door car running surface. 6, a V-shaped groove 7 for driving a door car and a descent running surface 8 for a door are provided in order toward the vertical frame T side. Each of the engaging portions 9 is engaged with and fixed to the mating groove 3, and the engaging portion 9 has a contact surface 9c for contacting the engaging groove bottom surface 3c and a longitudinal direction. It has taper surfaces 9a and 9b which serve as guides for engaging with the engaging groove 3 on the left and right sides, and an extension portion 19 is provided from the door roller down traveling surface 8 to the vertical frame T side. The upper surface of the engaging portion 9 is inclined upward toward the upper surface of the V-shaped groove portion 17 forming the door-carrying V-shaped groove 7, and the door roller downward traveling surface 8 extends from the upper surface of the V-shaped groove portion 17 to the engaging portion. It descends toward the upper surface of 9 and faces the reaction traveling side of the door car R, and the door car ascending travel surface 6, the door car running V-shaped groove 7 and the door car descending travel surface 8 are continuous, and the door car ascend travel. The door car R is braked on the surface 6 and the recoil travel of the door car R is restricted on the door car down traveling surface 8.

Since the sliding door device of the present invention has the above-mentioned structure, the rail member 1 is attached along the concave groove previously provided in the longitudinal direction of the lower frame G, and the V-shaped groove 7 for running the door roller of the braking member 5 is directed upward. 2, the contact surface 9c of the engaging portion 9 is directed downward, and as shown in FIG. 2, from the door roller running groove 2 side of the rail member 1 toward the inside of the engaging groove 3,
When pushed in from the side of the door car running surface 8 side, the engaging portion 9 will come into contact with the contact surface 9
Tapered toward left and right in the longitudinal direction is tapered toward 9c
Since the a and 9b are formed, the tapered surfaces 9a and 9b are guided along the inclined traveling surfaces 2a and 2b of the door roller traveling groove 2 and pass through while elastically deforming the traveling groove lower end width S of the door roller traveling groove 2, It elastically returns to the position where it passes through the running groove lower end width S, locks and locks in the engaging groove 3, and the contact surface 9c contacts the engaging groove bottom surface 3c and the V-shaped groove portion 17 contacts the door roller running groove 2. The door car ascending traveling surface 6 and the door car descending traveling surface 8 which are fixed to each other and are continuous to the door car traveling V-shaped groove 7 are also continuous to the door car traveling groove 2. The locking and fixing position of the braking member 5 with respect to the rail member 1 is determined by the door roller mounting dimension L from the door contact surface p of the sliding door P to the mounting position of the door roller R, and the door contact surface p of the sliding door P contacts the vertical frame F. At this time, the door roller R is locked and fixed so that the door roller R is located slightly closer to the vertical frame F side than the door roller down traveling surface 8.

In the sliding door P with the door roller R that runs along the rail material 1 with the braking member 5 fixedly locked, the door roller R is normally the point A in FIG. 1, that is, the door roller running groove 2 as shown in FIG. When the sliding door P travels in abutment with the inclined traveling surfaces 2a, 2b of the sliding door P toward the vertical frame F and before the sliding surface P of the sliding door P hits the vertical frame F, first, as shown in FIGS. Point B, that is, FIG.
As shown in (b), after riding on the door car ascending travel surface 6 of the braking member 5 from the door car traveling groove 2 and traveling along the door car ascending travel surface 6, point C in FIGS. 1 and 3, that is, FIG. As shown in FIG. 1 and FIG. 3, at the point C of FIG. 1 and FIG. 3, riding on the door car traveling V-shaped groove 7 from the door car ascending traveling surface 6 and traveling along the door car traveling V-shaped groove 7.
That is, as shown in FIG. 4D, the vehicle travels from the V-shaped groove 7 for running a door vehicle along the door running surface 8 to the vertical frame F from the door running surface 8.
The vehicle runs toward the side, and the door-contact surface p of the sliding door P collides with the vertical frame F.
When the door car R rides on the door car ascending traveling surface 6 and travels, a part of the running energy E of the sliding door P is converted into the pushing force of the sliding door P, whereby a braking effect is exerted and the braking member 5 is railed. Since it is a soft material having a larger frictional resistance than the material 1, the braking effect by the frictional resistance with the braking member 5 also acts.

Even if the door roller R of the sliding door P gets over the braking member 5 and the door contact surface p of the sliding door P collides with the vertical frame F, the running energy E of the sliding door P is reduced by the braking member 5, so the collision force is reduced. Is weakened, and repulsion at the time of collision is reduced. That is, even if the sliding door P collides with the vertical frame F and tries to return due to the recoil, most of the running energy E of the sliding door P is absorbed by the braking member 5, and even if the sliding door P returns due to the recoil, the recoil of the door roller R occurs. It is not possible to get over the door-vehicle down-traveling surface 8 provided on the traveling side, that is, it is not possible to reversely run, and as a result, the door stop surface p of the sliding door P stops at the position in contact with the vertical frame F. When the sliding door P travels away from the vertical frame F side in a direction away from the vertical frame F side, if the door car R rides over the door car downward traveling surface 8 and presses the door car running V-shaped groove 7 to such an extent that the sliding door P is in the vertical frame F side as before. Can run away from.

[0008]

EXAMPLE A rail material 1 is an extruded aluminum alloy material. As shown in FIG. 4, flange portions 1a and 1b are projected from the upper ends of the groove side walls 3a and 3b to the sides, and a mounting portion 1c for the lower frame G is provided. Is provided. The braking member 5 is formed of durable soft synthetic resin, soft rubber, or the like, and is provided on the closing side of the sliding door P, on the opening side of the sliding door P, and on the closing side and the opening side. There are cases where it is provided in both,
The engagement portion 9 may have any shape as long as it can be locked and fixed to the engagement groove 3 by utilizing elasticity, and the door roller traveling V-shaped groove 7 is not limited to one formed at an acute angle θ. Alternatively, the same purpose can be achieved even if the dish-shaped groove is in contact with the outer peripheral surface of the door roller R and is continuous with the door roller rising traveling surface 6. Even if the extension portion 19 of the engaging portion 9 is omitted, the substantially same purpose is achieved. By forming each of the rail member 1 and the braking member 5 symmetrically with respect to the longitudinal direction, the rail member 1 can be attached to the lower frame G and the braking member 5 can be attached to the rail member 1 freely. The braking effect of the door car R is not limited to the action of riding on the door car ascending traveling surface 6 and the frictional resistance with the braking member 5, and the traveling energy E of the sliding door P is also obtained while traveling along the door car traveling V-shaped groove 7. Since a part of is converted into the pushing-up force of the sliding door P, there is also a braking effect. The sliding door device of the present invention is a sliding door screen equipped with a door roller R,
It can also be applied to sliding sliding doors, partition doors, entrance sliding doors, hanging doors, etc.

[0009]

Since the sliding door device of the present invention is as described above, it has the following effects. In the sliding door device according to the first aspect of the present invention, since the attachment of the braking member to the rail member does not require bonding or screwing, workability at the site is improved and maintenance is simplified. Moreover, since the braking member locks and fixes the engaging portion provided over the entire length in the engaging groove, and the engaging portion is in contact with the bottom surface of the engaging groove, not only is there no disengagement or waviness due to running of the door roller, It is possible to increase the braking effect by lengthening the running surface of the door car. Further, since the braking member is made of a soft material, the frictional resistance with the door roller is large, the braking effect is high, and the running noise of the door roller is quiet. Further, since the engaging portion has a tapered surface that serves as a guide when locked, the locking and fixing of the engaging portion with respect to the engaging groove becomes light. According to the sliding door device of claim 2, in addition to the effect of claim 1, since the locking and fixing dimension of the engaging portion with respect to the engaging groove is long, the fixing of the braking member is further strengthened, and the curling due to the recoil running of the door roller is also possible. Less.
