In the second mounting body 20, a support member 40 that supports the wheel 30 configured to be able to change the position of the wheel 30 in the front-rear direction and the up-down direction is provided. The wheel 30 is connected to the support member 40 via a wheel base 31 and a connecting member 32.
It is connected to the. On the wheel base 31, a total of four rollers 33 arranged symmetrically on the front and rear side surfaces with the connecting member 32 interposed therebetween are rotatably supported, and the rollers 33 run stably on the rails provided on the side of the gate. be able to.

The support member 40 includes a vertical adjustment mechanism 50 for adjusting the amount of protrusion of the wheel 30, and the position of the support member 40 can be adjusted back and forth to adjust the position of the wheel 30 in a direction perpendicular to the moving direction. The front and rear adjustment mechanisms 60 are connected to each other, and the operation units 55 and 66 of the two adjustment mechanisms 50 and 60 are connected.
Is provided outside the guide member 22 constituting the second mounting body 20.

As the first mounting main body 10, two plate-like bodies 11, 11 are arranged facing each other in the upper half, and a space is formed therein. The frame portion 21 of the second mounting main body 20 is fitted into this space, and is provided at the upper end of the plate-like bodies 11 and 11 and is formed by protruding pieces 11a and 1 that are bent toward each other.
1a prevents the frame portion 21 from coming out upward. The lower half of the first mounting main body 10 is formed with a guide base 1 which is formed so as to protrude wider than between the upper plate-like bodies 11.
3 and the upper portion of the mounting hole B is narrower than the width of the guide base 13 in a state where the first mounting main body 10 is inserted and mounted from the side in the door boring mounting hole B. The upper half of the mounting hole B is locked, so that the mounting body is prevented from coming out upward. In addition, the first mounting body 1
The through hole 13a for introducing the lock member 24 in the same direction as the direction of insertion into the mounting hole B is formed in the 0 guide base 13. A lock member locking hole 13c for locking the lock member 24 is formed in a side wall near the middle from the entrance side of the through hole 13a to the vicinity of the middle to introduce the lock member 24. The back side is formed as an insertion hole 13b of the fixing screw 14 so as to have substantially the same outer diameter as the screw 14.

The frame portion 21 of the second mounting body 20 is a box-shaped body having an open top, and a support member 40 for supporting the wheel 30 is inserted therein. The first mounting member 1 is attached to the frame 21.
An entrance-side guide member 22 is provided on a side opposite to the zero. The guide member 22 has a first longitudinal cross-sectional shape in the width direction.
It has the same cross-sectional shape as the mounting main body 10, and when the second mounting main body 20 is coupled to the first mounting main body 10, the outer shape matches, and the inner shape of the mounting hole B matches. A through hole 22a having the same axis as that of the through hole 13a of the guide base 13 is provided below the guide member 22, and a fixing rotating member 23 is inserted through the through hole 22a. A substantially oval lock member 24 is attached to the tip of the rotating member 23, and the lock member 24 is engaged with the lock hole for the lock member of the guide base 13 in a state where the second attachment main body 20 is coupled to the first attachment main body 10. 13c
Reach the position. Then, the rotation member 23 is rotated 90 degrees to lock the lock member 24 in the lock member locking hole 13c. Thus, when the second mounting main body 20 and the first mounting main body 10 are connected and the first main body 10 is fixed to the mounting hole B, the second mounting main body 20 is also fixed.

The support member 40 is formed in a substantially U-shape in plan view by connecting substantially rectangular plate-like bodies 41, 41 to each other and connecting a part of the short sides thereof. A screw hole 41a is formed in an upper portion near the member 22, and a screw shaft 61 of the front-rear adjustment mechanism 60 is screwed. Screw shaft 6
A second gear 62 is fixedly attached to one end, and the support pin 26 as a support shaft of the screw shaft 61 and the second gear 62 is inserted therethrough. Both ends of the support pin 26 are
a, and the end faces thereof are plate-like bodies 11, 1
The support pin 26 is attached so as to be in contact with the inner surface and not move in the axial direction of the support pin 26. The portion of the plate-like body 41 of the support member 40 facing the second gear 62 has a stepped shape, and a gap corresponding to the thickness of the second gear 62 between the plate-like body 11 and the plate-like body 41. Is provided so that the second gear 62 can freely rotate. With the above configuration, when the screw shaft 61 rotates, the screw shaft 61 does not move in the axial direction, but the support member 40 side screwed to the screw shaft 61 moves in the axial direction of the screw shaft 61, and the front-rear position of the support member 40 is changed. It is determined.

The plate-like members 41, 41 of the support member 40 are formed with laterally oblong support holes 41b at positions away from the holes 41a. The frame portion 21 facing the support hole 41b is formed with a vertically elongated oval support hole 21a, and a support pin 42 is inserted into the support hole 21a and the support hole 41b. 30 connecting members 32 are supported. Therefore, the support pin 42 is positioned at the intersection of the vertically long support hole 21a and the horizontally long support hole 41b, whereby the wheel 30 is positioned vertically.

The vertical adjustment mechanism 50 for positioning the wheel 30 in the vertical direction includes a notch 41 formed in an inverted U-shape from the lower end below the hole 41a of the support member 40.
c, a pin 51 is loosely fitted, and a height adjusting screw 52 is screwed into a female screw portion 51a formed in the center of the pin 51. The height adjusting screw 52 is
The height adjustment screw 52 is fixed in the axial direction by a ring 53 attached to the tip of the screw and inserted into the operation unit 55. Therefore, when the height adjusting screw 52 is turned, the height adjusting screw 52 is stopped, and the pin 51 moves in the axial direction of the height adjusting screw 52. When the pin 51 moves, the support member 40
Since it is supported by the frame portion 21 at the position of the support pin 26, the connection member 32 rotates by the amount of movement of the pin 51 about the support pin 26, and when the support member 40 rotates, the connecting member 32 is connected via the support pin 42. Move up and down. Connecting member 3
When 2 moves, the length by which the connecting member 32 protrudes from the support member 40 changes, and the position of the roller 33 changes in the vertical direction. Therefore, for example, when the distance to the roller 33 becomes shorter, the roller 33 is supported by the rail, so that the main body side comes closer to the rail, and as a result, the vertical position of the sliding door rises by that much. Become.

The front-rear adjustment mechanism 60 includes a first gear 6 meshing with the second gear 62 in a direction in which the axis is orthogonal to the second gear 62.
Reference numeral 3 is attached to the front-rear adjustment shaft 64. The front-rear adjustment shaft 64 is inserted into the entrance-side guide member 22, and the operation part 66 has a head exposed to the outside. The front-rear adjustment shaft 64 is fixed by a retaining member 65 provided on the frame portion 21 so as to rotate only. Therefore, when the front-rear adjustment shaft 64 is rotated via the operation unit 66, the rotation is transmitted from the first gear 63 to the second gear 62, and the screw shaft 61 is rotated and screwed to the screw shaft 61 as described above. Can be moved in the front-rear direction.

The operation of the door wheel 1 of this embodiment will be described.
When attaching the door roller 1 to the sliding door, the first mounting body 1
First, the first mounting body 10 is inserted into the door frame mounting hole B of the upper frame A from the side, and the fixing screw 14 is passed through the insertion hole 13b. First
The mounting body 10 is fixed. Next, the second mounting body 20 is inserted in the lateral direction from the frame portion 21 side, and the frame portion 21 is
Fit between 1 and 11. Then, the fixing rotating member 23
Is rotated by 90 degrees to lock the lock member 24 inserted together with the second mounting member 20 in the lock hole 13c.
The mounting body 20 is coupled to the first mounting body 10. Thereby, the first mounting main body 10 and the second mounting main body 20 can be integrated and mounted in the mounting hole B.

Therefore, in the door roller of this configuration, the first mounting main body 10 and the second mounting main body 20 are divided and the first
The mounting body 10 is mounted on the sliding door A, and the second side is mounted on the rail side.
With the roller 33 on the mounting body 20 side inserted in the rail in advance, the second mounting body 20 side can be inserted into the sliding door A to assemble, and the door wheel can easily be mounted on the sliding door. Become. For this reason, it has conventionally been very difficult to insert a roller into a rail with a door roller mounted on a sliding door, but this problem can be solved.

When adjusting the height of the sliding door, that is, the position in the vertical direction, the vertical adjustment mechanism 50 for adjusting the position of the wheel 30 is used. When the height adjustment screw 52 is rotated clockwise through the operation unit 55,
The pin 51 screwed into the screw 52 moves only by the pitch of the rotation of the pin 52 toward the inlet side guide member 22 in the axial direction of the screw 52 because the screw 52 can only rotate. For this reason, although the pin 51 moves the support member 40, the support member 40 is supported by the frame 21 by the support pin 26, so that the support member 40
In the direction. Then, the connecting member 33 moves with the rotation of the support member 40, and the roller 33 side approaches the main body side. However, since the roller 33 side is supported by the rail, as a result, the roller 33 side does not move and the door wheel 1 does not move.
The side is raised by that amount, and the vertical position of the sliding door can be raised to change the position.

Conversely, when the height adjustment screw 53 is rotated counterclockwise, the support member 40 rotates about the pin 26 in the direction of the symbol n by the movement of the pin 51 and moves in the direction in which the connecting member 33 comes out. The distance between the main body and the roller 33 increases,
3 is supported by rails, and its vertical position does not change, and as a result, the position of the sliding door is lowered. When adjusting the position of the sliding door in the front-back direction, the front-back adjustment mechanism 60 is used. When the front-rear adjustment shaft 64 is rotated clockwise through the operation unit 66, the first gear 63 rotating with the shaft 64 is rotated.
, The second gear 62 rotates counterclockwise to rotate the screw shaft 61 counterclockwise. The screw shaft 61 is supported by the support pin 26. The support pin 26 and the screw shaft 61
The support pin 26 and the screw shaft 61 are fixed in the axial direction since the support pin 26 and the screw shaft 61 are sandwiched between the support pins 1 and 11. For this reason, the support member 40 moves to the back (symbol p) of the support pin 26 in the axial direction by the pitch of the screw in which the screw shaft 61 rotates via the screw hole 41 a screwed to the screw shaft 61. When the support member 40 moves, the position of the roller 33 with respect to the main body changes correspondingly through the connecting member 32.
Is supported by the rail, so that the hanging fulcrum position of the sliding door A shifts to the back side, and as a result, the sliding door is suspended from the front side of the rail, and the front and rear positions of the sliding door A Can be adjusted.

Conversely, when the front / rear adjustment shaft 64 is rotated counterclockwise, the support member 40 moves to the front side, so that the hanging fulcrum position of the sliding door moves to the front side, but the rail side is fixed. As a result, the sliding door moves to the back side (rear side) as a result. Therefore, since the front and rear adjustment of the sliding door can be performed, the distance between the sliding doors can be adjusted, and the position where the sliding door contacts the pillar can be changed in the front and rear direction.

As described above, in this embodiment, since the first mounting main body 10 and the second mounting main body 20 are divided, the mounting to the mounting hole A can be easily performed, and both the main body 10 and the second mounting main body 20 can be easily mounted. Can be easily performed only by rotating the rotation member 23 for fixing. In addition, since the vertical position or the front-back position of the sliding door can be adjusted simultaneously or selectively, the position of the sliding door can be more accurately adjusted.

Further, since the front-rear adjustment mechanism 60 can be operated by using the two gears 63 and 62, the operation can be performed from a direction different from the operation direction, and the adjustment can be performed from the prospective side of the sliding door. It can be carried out. In addition, the vertical adjustment mechanism 50 adjusts the load of the wheel 30 to the support pin 26 and the pin 5
Since the configuration is such that the pin 1 receives the load, the load applied to the pin 51 is reduced, and the operation of the height adjusting screw 52 can be performed lightly.

FIG. 4 shows another embodiment of the wheel 30 in which a wheel base 31 is formed in a downwardly-curved shape and a roller 33 is supported on the wheel base 31. In this case, a rail C as shown in FIG. The rail C is formed by curving both ends having a U-shaped cross section with an inner radius, and the roller 33 travels in the curved portion C 'while touching the ground.

FIG. 6 shows another embodiment, in which the door roller of this example is mounted on a lower frame of a sliding door.
The schematic structure of the door roller 2 is the same as that of the door roller 1 described above, except that the positions of the wheels are inverted in the vertical direction. Corresponding portions have the same reference characters allotted, and redundant description will be omitted. . The door roller 2 is not formed in a form in which the mounting body 15 is separated, but is formed in a box-like body having an open lower surface.
5, a support member 40 is provided. And
The wheel 35 has a configuration in which a roller portion is directly supported by the support member 40. The vertical adjustment mechanism 50 and the front-rear adjustment mechanism 60 have the same configuration.

The door roller 2 is mounted on a door roller mounting hole formed in a corner portion of a lower frame of a sliding door, and is fixed with fixing screws 18 and 19. The vertical and vertical adjustment of the sliding door can also be performed in the same manner as in the above embodiment using the vertical adjustment mechanism 50 and the front and rear adjustment mechanism 60. In each of the above-described embodiments, an example in which two spur gears are used as the configuration in which the operation is performed from a direction orthogonal to the moving direction of the support member in the front-rear adjustment mechanism has been described. Alternatively, as shown in FIG. 7, a worm gear 69 may be used.

[0029]

As described above, according to the door roller with the position adjusting mechanism of the present invention, the vertical position of the sliding door is adjusted by operating the vertical adjusting mechanism, thereby adjusting the vertical position of the sliding door. By operating the adjusting mechanism, the front and rear positions of the sliding door can be adjusted, so that the position of the sliding door can be appropriately adjusted. Since these adjustment operations can be performed from the outside of the mounting body, the adjustment can be performed while the sliding door is in the used state.

The vertical adjustment mechanism or the front-rear adjustment mechanism can be adjusted by selecting both or one of them, and the vertical or front-rear adjustment of the sliding door can be performed more accurately. Further, the door wheel with a position adjusting mechanism according to the present invention can handle both the upper frame and the lower frame of the sliding door, which is convenient.

Furthermore, since the integrally formed body Mounting and the support member detachably, first a mounting body attached to the attachment hole of the pull difference door, can be coupled by attaching a subsequent support member, pull It becomes possible to easily mount the door roller on the difference door.
