Japanese Unexamined Patent Publication No. 2013-213312

When the opening / closing door is lifted, a contact noise is generated when the moving roller comes into contact with the upper rolling surface. In the technique of Patent Document 1, it is possible to prevent the housing from being lifted, but it is not possible to prevent the generation of contact noise with the upper rolling surface when the moving roller is lifted.

The present invention has been made in view of the above circumstances, and an object of the present invention is a guide structure of a moving roller capable of reducing the contact noise between the moving roller and the upper rolling surface, and a sliding door using the guide structure. To provide the equipment.

In order to solve the above-mentioned problems, the present invention has a guide structure for moving rollers attached to the opening / closing door side to move in the opening / closing direction along a guide rail provided on the building side. The guide rail is provided with a lower rolling surface that the lower side of the moving roller contacts when opening and closing, and an upper rolling surface that is located on the upper side of the moving roller at intervals, and rotatably supports the moving roller. A muffling roller is provided on the main body, and the upper side of the muffling roller is arranged higher than the upper side of the moving roller, and the upper side of the muffling roller can be moved up and down by the elasticity of the main body or the muffling roller. It is characterized by being configured in.

Further, the muffling roller may be arranged so that its upper side is always in contact with the upper rolling surface of the guide rail.

Further, the moving roller is provided at a position away from the hanging source of the opening / closing door, and the muffling roller can be arranged adjacent to the moving roller at the distant position.

Further, the outer peripheral surfaces of the moving roller and the muffling roller are formed into a curved surface, and the upper rolling surface and the lower rolling surface of the guide rail are curved so as to match the outer peripheral surfaces of the moving roller and the muffling roller. May be formed in.

On the other hand, it is a sliding door device provided with the guide structure of the moving roller according to any one of claims 1 to 4, and is a closer for adjusting the position and movement of the opening / closing door moving in the opening / closing direction, or It is characterized in that a braking device is provided.

In the guide structure of the moving roller according to the present invention, a muffling roller is provided in the main body portion that rotatably supports the moving roller, and the upper side of the muffling roller is arranged higher than the upper side of the moving roller, and the main body is formed. Since the upper side of the muffling roller can be moved up and down by the elasticity of the part or the muffling roller, when the opening / closing door is lifted, the muffling roller moves to the upper rolling surface of the guide rail before the moving roller. Contact. At this time, the sound deadening roller elastically moves up and down, so that the force when the moving roller comes into contact with the upper rolling surface is buffered. As a result, the contact noise when the moving roller comes into contact with the upper rolling surface can be suppressed to be small.

Further, since the sliding door device according to the present invention is provided with a closer or a braking device for adjusting the position and movement of the opening / closing door that moves in the opening / closing direction, the sliding door device moves when the closer or the braking device operates. The roller may lift. At this time, the contact noise when the moving roller comes into contact with the upper rolling surface can be suppressed to a small value.

It is a front view of the sliding door device provided with the guide structure of the moving roller which concerns on embodiment of this invention. It is a front view of a guide device. It is an enlarged view of the part A of FIG. The second roller portion is shown as a single unit, (A) is a perspective view seen from an obliquely upper right side, and (B) is a perspective view seen from an obliquely lower right side. It is an exploded perspective view of FIG. 4A. This is a first modification of the guide structure of the moving roller, and corresponds to the XX cross-sectional view of FIG. This is a second modification of the guide structure of the moving roller. This is a third modification of the guide structure of the moving roller. This is a fourth modification of the guide structure of the moving roller.

Hereinafter, the guide structure of the moving roller according to the embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a front schematic view of a sliding door device H provided with a guide structure for a moving roller according to an embodiment of the present invention, and FIG. 2 is a front view of the first guide device 10. Further, FIG. 3 is an enlarged view of part A in FIG. Further, FIG. 4 shows the second roller portion 14 as a single unit, (A) is a perspective view seen from the diagonally upper right side, (B) is a perspective view seen from the diagonally lower right side, and FIG. It is an exploded perspective view.

The vertical and horizontal directions used in the present embodiment refer to the directions shown in FIG. 1 (the direction in which the user views the opening / closing door 2 from the front), and the front-rear direction refers to the paper depth direction of FIG. say. Further, the opening / closing direction of the opening / closing door shall mean the left-right direction.

As shown in FIG. 1, the sliding door device H provided with the guide structure of the moving roller includes a guide rail 1 attached to the upper part of the opening on the building side, and an opening / closing door 2 that moves in the opening / closing direction along the guide rail 1. It is composed of.

As shown in FIG. 1, the guide rail 1 extends substantially horizontally in the left-right direction, and the opening / closing door 2 is opened / closed along the guide rail 1. Further, the opening / closing door 2 is attached so that the left and right corners are suspended, and is supported by the guide rail 1 via a moving roller 21 (details will be described later) provided on the upper side of the opening / closing door 2. ..

The guide rail 1 is provided with a lower rolling surface 1a and an upper rolling surface 1b. The lower rolling surface 1a and the upper rolling surface 1b are positioned so as to sandwich the moving roller 21 up and down with the moving roller 21 assembled to the guide rail 1. When the opening / closing door 2 is normally opened / closed, the moving roller 21 comes into contact with the lower rolling surface 1a due to the weight of the opening / closing door 2 and rolls on the lower rolling surface 1a.

Further, the upper rolling surface 1b is arranged at a position spaced apart from the moving roller 21 in the vertical direction. The moving roller 21 comes into contact with the upper rolling surface 1b only when the opening / closing door 2 is lifted upward. Further, the position of the upper rolling surface 1b is regulated in the vertical direction so that the opening / closing door 2 is not lifted further by the moving roller 21 coming into contact with the upper rolling surface 1b.

A first guide device 10 for moving the left side of the opening / closing door 2 in the opening / closing direction is attached to the left corner of the opening / closing door 2. Further, a second guide device 17 for moving the right side of the opening / closing door 2 is attached to the right corner portion. A hanging portion 11 is attached to the lower side of the first guide device 10 and the second guide device 17, respectively. Further, the hanging portion 11 is attached so as to be embedded in the left corner portion and the right corner portion of the opening / closing door 2, respectively, and is detachably attached to the first guide device 10 and the second guide device 17, respectively. ..

As shown in FIG. 2, the first guide device 10 is located on the left side of the first roller unit 12, the mechanism unit 13 located on the right side of the first roller unit 12, and further to the right side of the mechanism unit 13. It is composed of a second roller portion 14 to be used.

The above-mentioned hanging portion 11 is detachably attached to the lower side of the first roller portion 12. Further, as shown in FIGS. 1 and 2, the first roller portion 12 is provided with a moving roller 21 that rotates about a rotation shaft 21a extending in the front-rear direction. There are two moving rollers 21 at intervals on the left and right, and two (four for convenience) are similarly provided on the back side.

Various mechanisms (for example, a closer, a braking device) for adjusting the position and movement of the opening / closing door 2 are attached to the mechanism unit 13. For example, the closer, which is an example of this mechanism, moves the opening / closing door 2 to a gently closed state when the opening / closing door 2 is closed, and is a captured member provided on the guide rail 1 side (not shown). ) Is captured at a predetermined position, and the captured member captured by using a spring or a damper is pulled to a predetermined position. Further, the braking device applies a brake to the opening / closing door 2 to gently close the opening / closing door 2 when the opening / closing door 2 is closed with a strong force. Since these closers and braking devices are conventionally used techniques, detailed description thereof will be omitted.

When the various mechanisms described above are not required, nothing is installed inside the mechanism unit 13 and the mechanism is used as it is.

As shown in FIGS. 2 to 5, the second roller portion 14 includes a main body portion 20 attached to the right end portion of the mechanical portion 13, and a moving roller 21 rotatably attached to the main body portion 20. It is composed of a muffling roller 22 which is arranged adjacent to the moving roller 21 and is rotatable with respect to the main body 20.

As shown in FIGS. 4 (A), 4 (B) and 5, the main body 20 includes a mounting portion 20a attached to the mechanism portion 13 and a moving roller mounting portion 20b located on the right side of the mounting portion 20a. It is composed of a muffling roller mounting portion 20c located on the right side of the moving roller mounting portion 20b. Each of these mounting portions 20a, 20b, and 20c is integrally formed of an elastic resin material. As long as the sound deadening roller mounting portion 20c has elasticity, the mounting portions 20a, 20b, and 20c may be formed separately.

The mounting portion 20a is formed in a substantially rectangular parallelepiped shape, is inserted from the right side into a mounting square hole (not shown) provided on the right end side of the mechanical portion 13, and the mounting screw 23 (see FIG. 3) is inserted from the lower side. It can be attached and detached by tightening.
As shown in FIG. 3, the moving roller mounting portion 20b projects from the right end side to the right side of the mechanical portion 13 in a state where the mounting portion 20a is assembled. Further, as shown in FIG. 5, the moving roller mounting portion 20b is formed with a rotating shaft mounting hole 24 that communicates in the front-rear direction. A rotary shaft 21a is inserted into the rotary shaft mounting hole 24, and two moving rollers 21 and 21 are rotatably mounted in the front-rear direction with the moving roller mounting portion 20b interposed therebetween.

The moving roller 21 attached to the first roller portion 12 and the second roller portion 14
It is the same as the moving roller 21 attached to the above, and is attached at the same height in the vertical direction. As a result, as shown in FIG. 1, the mechanism unit 13 arranged between them moves left and right while maintaining a substantially horizontal posture.

As shown in FIGS. 4 (A), 4 (B) and 5, the muffling roller mounting portion 20c extends from the upper right side of the moving roller mounting portion 20b toward the right side, and the tip portion on the right side thereof. A rotating shaft mounting hole 25 is formed in the shaft. A rotary shaft 22a is inserted through the rotary shaft mounting hole 25, and two sound deadening rollers 22 and 22 are rotatably mounted in the front-rear direction with the main body 20 interposed therebetween.

Further, the muffling roller mounting portion 20c is designed to be elastically bent up and down by reducing the thickness in the vertical direction. That is, when a force is applied in the vertical direction, the muffling roller 22 moves up and down due to this elasticity.

As shown in FIG. 3, the moving roller 21 and the muffling roller 22 are such that the upper side of the muffling roller 22 is higher by the dimension X than the upper side of the moving roller 21 in a state where the muffling roller mounting portion 20c is not bent. Is located in.

In this embodiment, the diameters of the moving roller 21 and the muffling roller 22 are equal (or may be the same). However, if the upper side of the muffling roller 22 is assembled so as to be located on the upper side by the dimension X, even if a muffling roller 22 having a small or large diameter (depending on the size of the diameter) is used. I do not care.

Further, in a state where the muffling roller 22 is assembled in the guide rail 1, as shown in FIG. 3, the moving roller 21 of the second roller portion 14 has a lower rolling surface 1a when the opening / closing door 2 is normally opened / closed. Touch and roll on it. On the other hand, the muffling roller 22 is not in contact with the lower rolling surface 1a, and is further provided with a gap of dimension Y with the upper rolling surface 1b.

On the other hand, as shown in FIGS. 1 and 2, the second guide device 17 arranged at the right corner of the opening / closing door 2 is provided with four moving rollers 21 in the front-rear and left-right directions, and the first guide device 10 The moving roller 21 receives the weight of the opening / closing door 2 and rolls on the lower rolling surface 1a of the guide rail 1 while being in contact with the lower rolling surface 1a. Further, the moving roller 21 of the second guide device 17 is also the same as the moving roller 21 of the first roller portion 12 and the second roller portion 14, and is arranged so as to have the same height. .. Further, a gap is provided between the moving roller 21 and the upper rolling surface 1b in the vertical direction as in the case of the other moving rollers 21.

Next, the operation of the guide structure of the moving roller according to the embodiment of the present invention will be described.
When the user opens the opening / closing door 2, a force is normally applied in the opening / closing direction, but when the force is directed diagonally upward, the opening / closing door 2 is lifted by the upward component force.

When the opening / closing door 2 is lifted, each moving roller 21 that rolls on the lower rolling surface 1a is also lifted together with the opening / closing door 2. At this time, the moving roller 21 of the first roller portion 12 of the first guide device 10 and the moving roller 21 of the second guide device 17 are the hanging sources of the opening / closing door 2, and the weight of the opening / closing door 2 directly moves the moving roller. Since it takes about 21, it is difficult to lift it upward. On the other hand, since the moving roller 21 attached to the second roller portion 14 of the first guide device 10 is located at a position separated from the hanging source of the opening / closing door 2 in the left-right direction, it is lifted upward with a slight impact or force. Sometimes.

Further, when various mechanisms such as a closer and a braking device are provided, a force for lifting the second roller portion 14 upward acts by the operation in those mechanisms. Therefore, the moving roller 21 may be lifted even if the opening / closing door 2 is not lifted. Therefore, the muffling roller 22 is provided on the second roller portion 14.

When the moving roller 21 of the second roller portion 14 is lifted, as shown in FIG. 3, the moving roller 21 that has been rolling on the lower rolling surface 1a is separated from the lower rolling surface 1a and rolled upward. It moves to the surface 1b (dimension X + dimension Y) and comes into contact with the upper rolling surface 1b.

At this time, before the upper side of the moving roller 21 comes into contact with the upper rolling surface 1b, the upper side of the muffling roller 22 moves by the dimension Y and first comes into contact with the upper rolling surface 1b. When the muffling roller 22 comes into contact with the muffling roller 22, the muffling roller 22 moves downward by the dimension X because the muffling roller mounting portion 20c bends downward due to its elasticity. Then, the moving roller 21 and the muffling roller 22 come into contact with the upper rolling surface 1b together and roll on the upper rolling surface 1b.

When the upper side of the sound deadening roller 22 comes into contact with the upper rolling surface 1b, the contact force is buffered by the elasticity of the sound deadening roller mounting portion 20c, so that the contact sound becomes small. Further, with respect to the moving roller 21 that comes into contact with the upper rolling surface 1b next to the sound deadening roller 22, the force that is lifted upward is buffered by the upper side of the sound deadening roller 22 contacting the upper rolling surface 1b first. , The contact noise is smaller than before.

Further, in a state where the moving roller 21 is in contact with the upper rolling surface 1b, the moving roller 21 is urged downward by the elasticity of the muffling roller mounting portion 20c. This urging force acts so as to quickly return the lifted opening / closing door 2 to its original position (position in contact with the lower rolling surface 1a).

According to the guide structure of the moving roller according to the embodiment of the present invention, the guide rail 1 has a lower rolling surface 1a that the lower side of the moving roller 21 contacts when opening and closing, and a space above the moving roller 21. A muffling roller 22 is provided on the main body 20 which is provided with a positioned upper rolling surface 1b and rotatably supports the moving roller 21, and the upper side of the muffling roller 22 is arranged higher than the upper side of the moving roller 21. At the same time, since the upper side of the muffling roller 22 can be moved up and down by the elasticity of the main body 20, when the opening / closing door 2 is lifted, the muffling roller 22 is placed on the guide rail 1 before the moving roller 21. It comes into contact with the upper rolling surface 1b. At this time, the sound deadening roller 22 flexes elastically, so that the force when the moving roller 21 comes into contact with the upper rolling surface 1b is buffered. As a result, the contact noise when the moving roller 21 comes into contact with the upper rolling surface 1b can be suppressed to a small value.

Further, since the moving roller 21 is provided at a position away from the hanging source of the opening / closing door 2 and the sound deadening roller 22 is arranged adjacent to the moving roller 21 at the distant position, the moving roller 21 is more easily lifted. The contact sound can be suppressed to a small value, and the effect obtained by the sliding door device H as a whole can be enhanced.

On the other hand, according to the sliding door device H according to the embodiment of the present invention, a closer or a braking device for adjusting the position and movement of the opening / closing door 2 moving in the opening / closing direction is provided. The moving roller 21 may be lifted when the braking device operates. At this time, the contact noise when the moving roller 21 comes into contact with the upper rolling surface 1b can be suppressed to a small value.

Although the guide structure of the moving roller according to the embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and various modifications and changes can be made based on the technical idea of the present invention. It is possible.

For example, in the present embodiment, in the normal open / closed state, the upper rolling surface 1b and the upper side of the muffling roller 22 are arranged with a space of dimension Y (see FIG. 3), but the space is not separated. It may be in a state of constant contact (making the dimension Y 0). Further, the muffling roller mounting portion 20c may be arranged in a slightly bent downward state, and the muffling roller 22 may be slightly urged on the upper rolling surface 1b.

Even with such a configuration, when the moving roller 21 is lifted and comes into contact with the upper rolling surface 1b, the sound deadening roller mounting portion 20c bends downward, so that the force for lifting the opening / closing door 2 is buffered. , The contact noise can be suppressed to a small level.

Further, by arranging the upper rolling surface 1b and the upper side of the muffling roller 22 in a state of being in contact with each other in advance, it is possible to suppress the swing of the opening / closing door 2 in the front-rear direction. 6A and 6B show a first modification of the guide structure of the moving roller, in which FIG. 6A shows a case where the muffling roller 22 is not provided, and FIG. 6B shows a case where the muffling roller 22 is provided. It should be noted that these figures correspond to the XX cross-sectional views of FIG.

When the muffling roller 22 is not provided, as shown in FIG. 6A, the upper side of the moving roller 21 is not in contact with the upper rolling surface 1b, so that the force at the time of opening and closing of the user causes the upper side and the front-rear direction to move. It is movable. Therefore, when the force for pushing the opening / closing door 2 to the rear side acts, the moving roller 21 swings in the B direction. On the other hand, when the muffling roller 22 is provided in a state of being in contact with the upper rolling surface 1b in advance, as shown in FIG. 6B, the moving roller 21 and the muffling roller 22 roll on the lower rolling surface 1a and upward. Since the moving surface 1b is urged up and down, the moving roller 21 is not only difficult to move in the vertical direction, but also difficult to swing in the B direction (or the opposite direction).

Further, as shown in FIG. 6B, the shapes of the lower rolling surface 1a and the upper rolling surface 1b are formed into curved surfaces according to the shapes of the outer peripheral surfaces of the moving roller 21 and the sound deadening roller 22. Further, the opening / closing door 2 is less likely to swing in the front-rear direction (shrink is small). Further, even if a runout occurs, it is possible to easily return to the normal position.

Further, in the present embodiment, the muffling roller 22 is provided only on the second roller portion 14 of the first guide device 10, but either the first roller portion 12 of the first guide device 10 or the second guide device 17 The sound deadening roller 22 may be provided on one or both of them.

For example, depending on the structure of the sliding door device H, the weight of the opening / closing door 2 may be supported not only on the upper side but also on the lower side. In such a structure, the weight of the opening / closing door 2 does not act (or is reduced) on the first roller portion 12 and the second guide device 17, which are described as suspension sources in the description of the present embodiment. The moving roller 21 of the door may also be lifted upward. Therefore, it is necessary to provide the muffling roller 22 in each of these parts so as to be adjacent to the moving roller 21.

FIG. 7 is a second modification of the guide structure of the moving roller, in which the muffling roller 22 is provided on the first roller portion 112 of the first guide device 110. Further, FIG. 8 is a third modification of the guide structure of the moving roller, and is a diagram in which the muffling roller 22 is provided on the second guide device 117.

As shown in FIG. 7, the first roller portion 112 is provided with a muffling roller 22 on the left side of the moving roller 21 and adjacent to the moving roller 21. Similarly, as shown in FIG. 8, the second guide device 117 is provided with muffling rollers 22 on the left side and the right side of the moving roller 21 and adjacent to the moving roller 21. As for these sound deadening rollers 22, the sound deadening roller mounting portion is elastically bent up and down, and the force of lifting the opening / closing door 2 is buffered by this elasticity. As a result, even if the moving roller 21 of the first roller portion 112 and the second guide device 117 is lifted, the contact noise with the upper rolling surface 1b can be reduced as compared with the conventional case.

Further, in the present embodiment, the sound deadening roller mounting portion 20c is flexed vertically by elasticity, but the same effect can be obtained with other structures. FIG. 9 is a diagram showing a fourth modification of the guide structure of the moving roller.

In the second roller portion 114 shown in FIG. 9, the sound deadening roller mounting portion 120c of the main body portion 120 is thickened vertically to increase the rigidity and prevent it from bending. On the other hand, the outer peripheral portion 122a of the sound deadening roller 122 is made of an elastic material, and the outer peripheral portion 122a bends when it comes into contact with the upper rolling surface 1b. Alternatively, the rotating shaft 22a may be bent up and down. As described above, even if the part to be bent is appropriately changed to form the structure, the same operation and effect as those of the present embodiment can be obtained.
