JP 2011-174264 A

In the above-mentioned door and wheel, an axle for rotatably supporting a wheel and a rocking shaft for pivotally supporting a wheel frame are inserted through an axle hole or rocking hole, and one shaft end thereof is crimped and fixed. It is provided in the wheel frame or the housing. For this reason, as shown in FIG. 7, a gap S is generated between the shaft 102 such as the axle and the rocking shaft only with the end portion which is not crimped and fixed to the hole 102 inserted. Since the door wheel 100 supports the weight of the shoji, if the gap S is generated in only one of the supported shafts 101, the shaft 101 tilts and unnecessary tilting occurs on the wheel and the shoji, thereby providing the shoji. There is a problem that the friction with the frame etc. being increased becomes large. In particular, when the wheel frame on which the wheel is pivotally supported is further pivotally supported by the housing as in the conventional door wheel described above, gaps accumulate and the unnecessary inclination of the wheel with respect to the housing becomes larger, and friction is also increased. There is a problem of becoming larger.
This invention is made in view of this subject, The place made into the objective is to provide the door roller and fixture which an unnecessary inclination of a wheel does not produce easily.

Door rollers of the present invention in order to achieve the above object, a door roller for movably supporting the child disabled while being guided by the rails, a first frame having a first opposing wall portions of a pair of opposed spaced apart from one another And between the pair of first opposing wall portions, and is inserted into the first opposing wall portion of either one of the pair of first opposing wall portions, and the other of the first opposing wall portions A plurality of axles which are fixed by caulking, a wheel rotatably supported on each of the axles and rolling on the rail, and a pair of second opposing wall portions facing each other at a distance from each other, The second frame in which the first frame is disposed between the pair of second opposing wall portions, and the second frame is bridged between the pair of second opposing wall portions, any of the pair of second opposing wall portions Is inserted into one of the second opposing wall portions, and is crimped to the other of the second opposing wall portions. Is, and a pivot shaft supporting the first frame swingably, and the axle and the pivot shaft, said axle and said first mutually different sides in the axial direction along the swing axis It is a door wheel characterized by being crimped and fixed to an opposing wall or the above-mentioned 2nd opposing wall.

  In the case where a plurality of shafts are respectively bridged between a pair of opposing wall portions, inserted into any one of the pair of opposing wall portions, and caulked and fixed to the other opposing wall portion. There is a gap between the shaft and the opposite wall through which the shaft is inserted, and no gap between the opposite wall which is fixed by caulking. For this reason, when the shoji is supported by the door wheel, the shaft is inclined due to the gap occurring only on one side. When the axle supporting the wheels and the swinging shaft supporting the first frame are crimped and fixed to opposite wall portions on different sides in the axial direction along the axle and the swinging axis as in the case of the door wheel described above Even if the first frame on which the wheels are supported is supported by the second frame via the pivot axis, the gap around each axis is on one side only in the axial direction. Since it does not accumulate, it is possible to suppress unnecessary inclination of the wheel.

In such a door wheel, it is preferable that a plurality of the first frames on which the wheels are supported be provided, and each of the first frames be swingable independently of each other.
According to such a door wheel, since the first frames on which the wheels are supported can be rocked independently of each other, it is possible to easily absorb irregularities in the rails and the like.

Such a door wheel has another swinging shaft for supporting the second frame, and has a third frame for swingably supporting the second frame via the other swinging shaft. The other rocking shaft is caulked and fixed to the first opposing wall or the second opposing wall on the side different from at least one of the axle and the rocking shaft in the axial direction. Is desirable.

  According to such a door wheel, since the other rocking shaft supporting the second frame and at least one of the axle and the rocking shaft are crimped and fixed to the opposing wall portions on different sides, the wheel is Even if the second frame that supports the first frame being supported is supported by the third frame, the gaps around each axis do not accumulate on only one side in the axial direction, so the wheel Unwanted inclination can be suppressed.

Further, a door roller for movably supporting the child disabled while being guided by the rails, a frame having a pair of opposing wall portions facing each other at a distance from each other, spanned between the pair of opposing walls, the A plurality of axles inserted through one of the pair of opposing wall portions and crimped and fixed to the other opposing wall portion, and rotatably supported by the respective axles It is a door provided with a plurality of wheels rolling on a rail, wherein at least one of the plurality of axles is crimped to the opposite wall different from the other axles. .

  According to such a door wheel, since at least one of the plurality of axles is crimped and fixed to the opposite wall different from the other axles, the axles crimped and fixed to the different opposite walls tilt with each other It is possible to suppress the unnecessary inclination of the wheel by regulating that. For this reason, it is possible to provide the door-wheel that an unnecessary inclination does not produce a wheel easily.

In such a door wheel, it is desirable that the wheel be configured to be tiltable with respect to the rail.
A door roller whose wheels can be inclined with respect to the rail does not come into contact with the seal material of the frame on which the door wheel is attached, and the seal material when the shoji is closed. It is used for fittings that become airtight upon contact. That is, the sealing material and the shoji are separated when running the shoji, and when the shoji is closed, the relative position between the frame and the shoji changes so as to be in close contact with the sealing material. At this time, if the unnecessary inclination of the axle is large, there is a risk that the shoji will come into contact with the sealing material when running the shoji and the load at opening and closing of the shoji will increase, or it will not be in close contact with the sealing material when the shoji is closed. is there. For this reason, the above-mentioned door roller in which the clearance around each axis does not accumulate on only one side in the axial direction and unnecessary inclination of the wheel is suppressed is more effective than the door roller in which the wheel can tilt with respect to the rail. Is suitable.

Moreover, it is a fitting characterized by having the said shoji provided with the said door wheel.
According to such a fitting, it is possible to provide a fitting having a shoji having a door wheel that is less likely to cause unnecessary inclination of the wheel.

  According to the door roller 7 of the present embodiment, as shown in FIG. 5, the axle 74 supporting the wheels 72 and the first rocking shaft 76 supporting the first frame 73 are caulked on different sides in the perspective direction The wheel 72 is fixed because one of the axle shaft 74 and the first rocking shaft 76 and the second rocking shaft 785 supporting the second frame 75 are fixed by caulking on different sides in the expected direction. Even if the supported first frame 73 is supported by the second frame 75 via the first swing shaft 76, the gaps around the axles 74 and around the first swing shaft 76 are one side. It is possible to suppress the unnecessary inclination of the wheel 72 because it does not accumulate only on the side.

  More specifically, the axle shaft 74 is inserted into one of the pair of first opposing wall portions 73a and caulked to the other, and the first rocking shaft 76 is formed of the pair of second opposing wall portions 75a. It is inserted into one and caulked and fixed to the other. For this reason, on the side where the axle 74 and the first rocking shaft 76 are inserted, there is a gap around the axle 74 and around the first rocking shaft 76, and on the side where the caulking is fixed Naturally there is no gap. For this reason, when the weight of the sliding door 4 acts on the door 7, the axle shaft 74 and the first rocking shaft 76 tilt.

Such inclination is caused by the gaps formed around the axle 74, the first rocking shaft 76 and the second rocking shaft 785. For this reason, when the gaps generated around the axle 74, the first rocking shaft 76 and the second rocking shaft 785 are formed only on one side in the expected direction, that is, the axle 74, the first rocking shaft 76 and If the second rocking shaft 785 is fixed by caulking on the same side in the perspective direction, the inclination may accumulate and the wheel 72, the first frame 73, and the second frame 75 may be largely inclined with respect to the mounting frame 79. There is. At this time, for example, in the sliding door 4 which must travel in a state of being separated from the sealing material 8 provided on the outdoor side, unnecessary inclinations of the wheels 72, the first frame 73, and the second frame 75 cause inclination to the outdoor side. If the size is increased, the load may be increased by traveling in contact with the seal member 8, or the seal member 8 may be worn and the air tightness can not be maintained. Further, in the sliding door 4 where the seal member 8 provided on the outdoor side must be in close contact with the lower rod 6 in a state in which the shoji is closed, unnecessary inclination of the wheel 72, the first frame 73, and the second frame 75 If the inward inclination is large, the sliding door 4 may not be drawn to an appropriate position when the sliding door 4 is closed, and the airtightness may not be maintained even if the sliding door 4 is closed. For this reason, it is possible to suppress the unnecessary inclination of the wheel 72 by making the axle 74, the first rocking shaft 76, and the second rocking shaft 785 different from each other in the expected direction by caulking.
In addition, since the wheel units 71 having the wheels 72 supported by the first frame 73 can rock independently of each other, it is possible to absorb the irregularities of the rail 2b.

  Moreover, according to the fitting 1 having the sliding door provided with the door roller 7 of the present embodiment, the fitting 1 having excellent airtightness provided with the sliding door 4 which can be opened and closed smoothly by suppressing unnecessary inclination of the wheel 72 is provided. Is possible.

Thus, in the case of the door roller 82 provided with the plurality of wheels 72, the wheels 72 supporting the wheels 72 are crimped and fixed to the first opposing wall portions 73a on different sides, so that the wheels 72 are provided. It is possible to suppress the unnecessary inclination of the
In the said embodiment, although the example in which the door roller 7 was equipped with the four wheels 72 was demonstrated, the number of the wheels 72 is not restricted to this.
In the said embodiment, although the fixture 1 provided with FIX shoji 3 and the sliding door 4 was demonstrated, not only this but a fixture type etc. of a mistake type may be sufficient, for example.

  Also, the above embodiments are for the purpose of facilitating the understanding of the present invention, and are not for the purpose of limiting the present invention.
