Description of the Related Art Conventionally, as a door braking device, for example, elastic pieces that resiliently press a guide member that is attached to a door plate and that moves on a rail provided on a door frame (a sill, a sill) are provided at both ends inside the rail. What is prepared for is known.

[0003] In this conventional door braking device, a door plate that is opened and closed is braked near the end of opening and closing by elastically pressing a guide member with an elastic piece, and each part is damaged by a collision between the door frame (vertical frame) and the door plate. Prevents the door from rebounding.

[0004]

In the conventional door braking device described above, in order to make the opening and closing movement of the door plate impossible, an elastic piece is provided in the middle part of the rail, so that braking cannot be performed during opening and closing of the door plate. There is a problem.

Means for Solving the Problems In order to solve the above problems, a door braking device according to the present invention employs the following means.

That is, according to the first aspect of the present invention, in a door braking device comprising an elastic piece mounted on a door plate and elastically pressing a guide member moving on a rail provided on a door frame, the elastic piece is fixed to the outside of the rail. The guide member protrudes near the opening of the rail and is exposed to the rail from the rail or a member for supporting the guide member outside the rail in a horizontal direction.

In this means, since the main body and the elastic piece are mounted so as not to disturb the movement of the guide member and are disposed inside the rail, the guide member is resiliently mounted by being mounted at an arbitrary position. The opening and closing movement of the door plate can be braked.

According to a second aspect of the present invention, in the door braking device of the first aspect, the elastic piece is provided with two protrusions for pressing the guide member along the moving direction of the guide member, and the guide member is provided between the protrusions.

According to a third aspect of the present invention, in the door braking device of the first or second aspect, the elastic piece is supported by an end of the main body and extends from the main body via a space along the moving direction of the guide member. It is characterized by being.

In this means, the elastic piece is provided with elasticity by the cantilever structure.

According to a fourth aspect of the present invention, in the door braking device according to any one of the first to third aspects, the main body has a hollow structure.

In this means, the impact force and the impact sound of the elastic pressure of the guide member by the elastic piece are attenuated by the hollow structure.

[0016]

Hereinafter, embodiments of a door braking device according to the present invention will be described with reference to the drawings.

In this embodiment, an apparatus used in the above-mentioned interlocking door opening / closing apparatus is shown.

This embodiment, as shown in FIG. 1, comprises a main body portion 1 and an elastic piece 2 and is attached to a door frame Pa of a door frame P which is formed by a frame Pa, a threshold Pb, and a vertical frame Pc. Then, the guide member G for non-loading type anti-vibration mounted on the upper portion of the door plate D is pressed.

As shown in FIGS. 1 and 2, the guide member G is composed of a deformable roller rotatably supported by a support shaft S projecting vertically from the door plate D, and is embedded in the Kamoi Pa. The door plate D is moved while rotating along the upper rail R with the opening E directed downward to open and close the door plate D. The guide member G has an internal roller portion G from an upper portion to a lower portion.
a, a tapered roller portion Gb, and an external roller portion Gc. The internal roller portion Ga and the tapered roller portion Gb enter the rail R. The outer roller portion Gc is exposed outside the rail R.

The door plate D is composed of a plurality of sheets. A link member J for interlocking opening and closing is attached to each door plate D. The door plate D has a load-type traveling guide member (not shown) attached to a lower portion thereof. The traveling guide member travels and moves along a lower rail (not shown) provided on a threshold Pb of the door frame P.

The main body 1 is made of a synthetic resin material such as polyacetal and is formed in a thin and elongated plate shape, and has a hollow structure provided with a hollow portion 11 on the upper surface. At both ends in the length direction of the main body 1, insertion holes 12 into which the mounting screws 3 are inserted are provided.

The main body 1 is brought into contact with the duck Pa of the door frame P near the rail R on the side of the lightening portion 11, and the door frame P is
To the Kamoi Pa. The fixing direction of the main body 1 is set such that the length direction of the main body 1 is substantially parallel to the direction in which the rails R are provided.

The elastic piece 2 is formed integrally with the main body 1 and extends in the longitudinal direction from the longitudinal end of the main body 1 through a slit-shaped gap 4 with the main body 1 and extends in the horizontal direction. Has elasticity. The cantilever structure of the elastic piece 2 with respect to the main body 1 makes it possible to easily provide elasticity by integral molding with the main body 1. Two protrusions 21 are provided in the length direction on the opposite side of the elastic piece from the main body 1, and a recess 22 is provided between the two protrusions 21. Projection 21
Is for repressing the guide member G. Depression 2
Reference numeral 2 is for releasing the elastic pressure on the guide member G. Further, the main body 1 is slightly extended along the projection 21 and the recess 22.
On the side, a step-shaped relief groove 23 is engraved in the length direction. The relief groove 23 is for avoiding the protruding portion of the guide member G (the lower end of the tapered roller portion Gb) (FIG. 5).
reference).

The elastic piece 2 projects near the opening E of the rail R by fixing the door frame P of the main body 1 to the door Pa.

According to this embodiment, since the structure is simple and can be manufactured by a synthetic resin molding technique, inexpensive and easy manufacture is possible. Further, since it is attached to the outside of the rail R, it can be attached to an existing door opening / closing device or the like.

In this embodiment, as shown in FIG.
The mounting position is selected at the opening / closing completion position of the middle door plate D excluding the two door plates P near the vertical frame Pc of the door frame P of the plurality of door plates D.

Therefore, when the intermediate door plate D is opened and closed in conjunction with the linking member J, the projection 21 on the front side of the elastic piece 2 is moved to the outer roller of the guide member G against the inertia which attempts to cross the opening / closing completion position. The portion Gc is attenuated by being elastically pressed in the horizontal direction,
The protrusion 21 on the rear side of the elastic piece 2 elastically presses the outer roller portion Gc of the guide member G in the horizontal direction and completely disappears. As a result, the outer roller portion Gc of the guide member G is
2 and the opening and closing movement of the door plate D is stopped.

In this inertia decay, as shown in FIG.
The elastic piece 2 that resiliently presses the outer roller portion Gc of the guide member G elastically inclines toward the main body portion 1 and exhibits gentle elastic resistance. Therefore, the damping function can be reliably achieved even with a weak opening / closing force such as inertia. In addition, the main body 1,
The gap 4 between the elastic pieces 2 and the hollow portion 11 of the main body 1 attenuate the impact force and the impact sound caused by the contact between the elastic piece 2 and the outer roller portion Gc of the guide member G. Therefore, generation of abnormal noise around the elastic piece 2 and the guide member G can be prevented, and damage can be prevented.

By applying an opening / closing force stronger than the above-described inertia to the door plate D, the outer roller portion Gc of the guide member G can extend beyond the recess 22 of the elastic piece 2 to the rear projection 21. It is. Therefore, it is possible to move the intermediate door plate D past and beyond the opening / closing completion position.

That is, the position of the mounting position can be freely selected, and in addition to the opening / closing completion position of the intermediate door plate D, it is attached to the opening / closing completion position of the door plate D near the vertical frame Pc of the door frame P, and the above-mentioned position is set. The same use as the conventional example can be provided. Further, it can be used as a stopper when the door plate D is to be opened halfway. Further, since the damping function can be reliably performed even with a weak opening / closing force such as inertia, the damping of the opening / closing movement of the door plate D (up to the stoppage of the door plate D) can be achieved in combination with another stopper mechanism. ) Can also be used only.

As described above, in addition to the illustrated embodiment, it is also possible to adopt a configuration in which the supporting member S for supporting the guide member G outside the rail R is elastically pressed by the elastic piece 2.

Further, it is also possible to adopt a configuration in which the load-type traveling guide member on the lower side of the door plate G is elastically pressed by the elastic piece 2.

Further, the present invention can be applied not only to a sliding door but also to a folding door.

[0034]

As described above, the door braking device according to the present invention can be mounted so as not to dispose the guide member inside the rail so that the main body and the elastic piece do not disable the movement of the guide member. Therefore, there is an effect that the opening and closing movement of the door plate can be braked at an arbitrary position.

Further, since the structure is simple, there is an effect that it can be easily manufactured at low cost.

Further, since it is attached to the outside of the rail, there is an effect that it can be attached to an existing door opening / closing device or the like.
