Description

[Detailed Description of the Invention] <Technical Field> This invention relates to a door roller mounting adjustment device, and more specifically, to a mounting adjustment device for adapting the door roller to sliding door sashes with different mounting dimensions.

<Prior art> When replacing the door roller that was previously attached to the sliding door sash due to failure or deterioration, if the new door roller for repair is exactly the same as the old door roller, it can be replaced with the sash. Although there are no installation problems, it is usually rare to be able to obtain a new car that is identical to the old one.

Therefore, repair door rollers are required to be flexible enough to easily accommodate differences in the structure and dimensions of the mounting holes of sliding door sashes that differ from manufacturer to manufacturer.

However, at present, there are no repair door wheels that can easily and quickly make the above installation adjustments.
Furthermore, even if installation adjustment is possible, if the adjustment mechanism becomes too complicated, the cost of the door roller becomes high and it becomes impractical, so further improvements have been desired.

In addition, if you want to use a specific new car that does not have a mounting adjustment function due to performance reasons, a device that can be inserted between the new car and the sliding door sash and adjust the mounting dimensions is required. Ru.

<Purpose> Therefore, the purpose of this invention is to eliminate the drawbacks of the above-mentioned prior art and to provide a mounting adjustment device that is easy to adjust for mounting on a sash and has excellent flexibility in terms of mounting dimensions and the like.

<Structure> In order to achieve the above object, a pair of mounting plates each having a horizontal sliding piece and a vertical expansion piece connected in an L-shape are arranged as expansion pieces. Place the sliding pieces on top of each other with the pieces facing each other,
A back plate on which a door roller mounting portion is formed is placed on the back side of the stacked sliding pieces, and the sliding piece and the back plate of each mounting plate are slidably connected in the direction in which the expanding pieces mutually expand. The rotating plate provided on the inner surface of the stacked sliding pieces is rotatably attached to the back plate by inserting the center rotating shaft part through the sliding piece, A mating protrusion is formed on the rotary plate, and a rotation operation part is formed in the center, and a row of teeth that can be mated with the mating protrusion of the rotary plate is formed on the inner surface of each expansion piece.
Furthermore, each sliding piece has an opening that exposes the door roller mounting portion inward at the location corresponding to the door roller mounting portion of the back plate, and the outer surface of each expanding piece has an opening for exposing the door roller mounting portion inward. It is characterized in that a protrusion for preventing movement is formed that presses against the inner wall of the mounting hole.

<Example> Next, an example of this invention will be described below with reference to the drawings.

Figures 1 to 3 are shown upside down compared to when in use, and 1 and 1 are a pair of mounting plates, with a sliding piece 10 in the horizontal direction and an expansion plate in the vertical direction, respectively. The piece 11 is bent into an L-shape and is integrally formed in a continuous manner. Then, with the expansion pieces 11, 11 facing each other and the sliding pieces 10, 10 overlapped, the left and right mounting plates 1, 1 are symmetrically assembled,
The entire structure is arranged in a U-shape.

Reference numeral 2 denotes a back plate, which has a flat plate shape with both ends slightly bent, and is placed in contact along the entire longitudinal direction with the back surface (lower surface in the figure) of the overlapping sliding pieces 10, 10. Mounting screw holes 20, 20, which serve as mounting parts for the door roller, are formed near both longitudinal ends of the plate 2.

Reference numeral 3 denotes a thick rotating plate, which is arranged at the center of the inner surfaces of the sliding pieces 10, 10 of the mounting plates 1, 1 combined in the U-shape, and has a rotating plate protruding from the center back surface of the rotating plate 3. The moving shaft 30 is inserted into the long holes 12, 12 formed along the transverse direction of both sliding pieces 10, 10, and the tip of the rotating shaft 30 is caulked to the back plate 2, so that it can freely rotate. It is pivoted on. Therefore, the sliding pieces 10, 10 and the back plate 2 are sandwiched between the rotating plate 3, and the sliding pieces 10, 10 and the back plate 2 are slid together along the elongated holes 12, 12. They are movably connected, and by sliding these sliding pieces 10, 10, the left and right expanding pieces 11, 11 can be expanded and moved. A Phillips groove 31 serving as a rotation operation section is recessed in the upper surface of the rotation plate 3, so that the rotation plate 3 can be rotated freely with a Phillips screwdriver.

In addition, the outer shape of the rotating plate 3 is approximately elliptical, and both ends of the longer diameter are sharply pointed to form the engaging protrusion 3.
2,32 are formed. And mounting plate 1,1
On the lower inner surfaces of the left and right expansion pieces 11, 11, tooth rows 13, 13 are provided in a triangular serrated shape along the longitudinal direction at the locations where the engaging protrusions 32, 32 come into contact with each other.
are formed, and these tooth rows 13, 13 are designed to mesh with the meshing protrusions 32, 32. Therefore, when the rotating plate 3 is rotated, the engaging protrusions 32, 3
2 engage sequentially along the tooth rows 13, 13 on both sides, and push the expansion plates 11, 11 to expand them.

Note that the tooth rows 13, 13 may be formed only in the vicinity of the rotation range of the rotation plate 3.

Next, in the sliding pieces 10, 10, elongated holes 14, 14, which serve as openings, are formed along the transverse direction at positions corresponding to the mounting screw holes 20, 20 of the back plate 2, respectively. The mounting screw holes 20, 20 are always exposed on the inner surface side of the sliding pieces 10, 10.

Near both upper and lower ends of the expansion pieces 11, 11, protrusions 15 protruding outward to prevent movement are formed, and in the case of the figure, a cut is formed in the expansion piece 11, and this cut The periphery is bent and raised outward to form a protrusion 15 having a sharp tip.

Cylindrical protrusions 21, 21 protruding toward the sliding piece 10 are formed on the back plate 2 on the right and left sides of the mounting screw holes 20, 20 in the longitudinal direction.
Screw holes 22, 22 for adjusting the height of the door roller are formed in the center. Elongated holes 16, 16, which serve as openings, are formed in the sliding pieces 10, 10 at positions corresponding to the height adjusting screw holes 21, respectively, along the transverse direction. Then, a back plate 2 is placed inside the elongated hole 16.
The protrusion 21 is inserted into the elongated hole 16, and the protrusion 21 slides within the elongated hole 16 as the expansion pieces 11, 11 move to expand. Therefore, the protrusions 21, 2
1 secures a sufficient screw length for the height adjustment screw hole 22, and is fitted into the elongated hole 16 formed near the left and right ends of the sliding pieces 10, 10, so that the rotation can be easily adjusted. The sliding pieces 10, 10 connected only at one point on the shaft 30 are prevented from rotating around the rotating shaft 30 and unable to maintain a parallel state, and the expanding pieces 11, 11 are always parallel to each other. It is possible to move and expand while facing each other.

The use of the door roller mounting device configured as described above will be explained with reference to FIGS. 4 to 6.

First, to explain the operation of the rotating plate 3, in FIG. Teeth row 1 of expansion pieces 11, 11
3 and 13, and as the rotating plate 3 is rotated in a direction in which the diametrical direction of the engaging protrusions 32, 32 coincides with the lateral direction of the sliding pieces 10, 10, that is, clockwise in the figure, the engaging The protrusions 32, 32 are the expansion pieces 11, 1
Push 1 left and right to expand and move it. Then, a tooth row 13 in which the meshing protrusions 32, 32 of the rotating plate 3 mesh with each other.
The position also gradually moves along the longitudinal direction.

However, contrary to the above, even if a force is applied in the direction of bringing the expansion pieces 11, 11 closer to each other, the tooth row 13 and the meshing protrusion 32 are engaged, so the rotating plate 3 is moved in the opposite direction. Therefore, the expanding pieces 11, 11 do not move in the narrowing direction. In addition, in order to move the expansion pieces 11, 11 in a direction to narrow the interval between them, the expansion pieces 11, 11,
It is sufficient to rotate only the rotating plate 3 without pressing the parts 11 against each other.

Next, to attach the mounting device to the sliding door sash S, as shown in Fig. 5, insert the mounting device into the mounting hole H of the sash S, and rotate the rotating plate 3 with a screwdriver or the like. , expand and move the left and right expansion pieces 11, 11 until they come into pressure contact with the left and right inner walls of the mounting hole H.

At this time, the outwardly projecting protrusions 15 of the expansion plates 11, 11 are pressed into contact with the inner wall of the mounting hole H so as to bite into the inner wall of the mounting hole H, thereby preventing the mounting device from moving after mounting and ensuring secure fixation.

In addition, by screwing the adjustment screws 4 into the height adjustment screw holes 22, 22 at both longitudinal ends of the back plate 2, and bringing the tips of the adjustment screws 4 into contact with the ceiling wall of the mounting hole H. Therefore, the insertion depth of the mounting device into the mounting hole H can be reliably adjusted, and the mounting device can be prevented from moving due to the load of the entire sliding door during use.

After attaching the mounting device to the sash S as described above, the door wheel 5 is inserted inside the mounting device, and as shown in FIG. 50, the mounting screws 6 are screwed into the mounting screw holes 20 of the back plate 2, and the door wheel 5 is fixedly mounted on the mounting device. Incidentally, on the outside of the mounting screw through holes 50, 50 of the door roller 5, through holes 51, 51 for inserting the adjusting screws are formed, and the adjusting screws 4 are inserted therethrough.

Also, when removing the door wheel 5, remove the mounting screw 6 and adjustment screw 4 to remove the door wheel 5 from the mounting device, and then rotate the rotating plate 3 of the mounting device in the opposite direction from when it was installed. By doing so, the pressure contact of the expansion plates 11, 11 against the inner wall of the mounting hole H can be released, and the mounting device can be removed from the mounting hole H.

Among the door roller mounting devices described above, in addition to installing only one rotating plate 3 in the center, two rotating plates 3 are installed symmetrically near both left and right ends in the longitudinal direction as shown in FIG. They can also be provided at different positions.
According to this modification example, the wheels 52 of the door roller 5 are
The rotation operation part 31 of the rotation plate 3 can be arranged at the left and right outer positions of the rotation plate 3. By forming the through holes 53, 53 for operation on the upper surface of the door wheel 5, the door wheel 5 can be left attached to the mounting device.
It becomes possible to rotate the rotating plate 3.

Therefore, unlike the method of use described in the above embodiment, before installing it on the sash S, the mounting device and the door wheel 5 are first integrally mounted with the mounting screws 6, and then the mounting device integrated with the door wheel 5 is attached. It can be inserted into the mounting hole H of the sash S, and in this state, the rotating plates 3, 3 are operated to expand the expansion plates 11, 11, and then fixed in the mounting hole H. In other words, the installation adjustment can be made while checking the installation condition of the door roller 5.
The installation position can be adjusted accurately, and the installation work can be done easily and quickly, which is preferable. Furthermore, in the modified example shown in FIG. 7 above, the height adjustment screw 4 is
Since it is configured to be attached further outward from both ends in the longitudinal direction, the door roller 5 and the height adjustment screw 4 can be attached and detached completely separately, which is very convenient.

In addition, as a mechanism for slidably connecting the sliding piece and the back plate, as shown in the figure, the sliding piece In addition to connecting the sliding pieces 10, 10 and the back plate 2, the sliding pieces 10, 10 and the back plate 2 can be slidably connected by a known mechanism such as an appropriate rivet or bolt provided separately from the rotating plate 3. They can also be concatenated.

Furthermore, in order to expand and move the expansion pieces 11, 11 while facing each other in a parallel state, a sliding guide mechanism by fitting the left and right elongated holes 16 and the protrusion 21 shown in the figure is used, and each sliding Moving pieces 10, 10 and back plate 2
An appropriate guide structure may be formed by fitting the concave and convex portions or the like.

Next, as for the shape of the rotating plate 3, as long as the engaging protrusions 32, 32 can be formed at both ends in the diametrical direction, the overall shape of the rotating plate 3 can be circular, in addition to the approximately elliptical shape shown in the figure.
Can be implemented in polygons and other free shapes. The engaging protrusion 32 may have a shape other than the triangular shape shown, as long as it is sharply pointed and can be reliably engaged with the expansion plates 11, 11. Further, the operating portion 31 can be freely changed into a slotted groove, a hexagonal hole, etc., depending on the shape of an operating tool such as a screwdriver. Furthermore, as a structure for rotatably attaching the rotating shaft 30 of the rotating plate 3 to the back plate 2, in addition to the caulking structure shown in the figure, the rotating shaft 30 is clamped to the back plate 2 with a nut, etc. , can be changed as appropriate.

Next, the shape of the tooth row 13 formed on the expansion pieces 11, 11 can be freely changed in accordance with the shape of the meshing projection 32 as long as it can mesh with the meshing projection 32 of the rotating plate 3. The tooth row 13 is recessed in the expansion pieces 11, 11, and the expansion pieces 11 are recessed.
It can also be formed to protrude from the inner surface of the.

Movement-blocking protrusion 15 formed on the expansion piece 11
As shown in the figure, the one with the claw-like tip is
It is press-contacted so as to bite into the inner wall of the mounting hole H, and is suitable for reliable mounting and fixing.
It can also be carried out on a small convex part with a part of it protruding outward.
The protrusion 15 can be formed not only at the end of the expansion piece 11 but also at the center.

Next, the openings formed in the sliding piece 10 at positions corresponding to the mounting screw holes 20 and the height adjustment screw holes 22 of the back plate 2 are
If exposed, in addition to the illustrated elongated holes 14 and 16,
This can be carried out freely with an appropriately shaped opening.

Furthermore, as a structure for attaching the door wheel 5 to the mounting device, in addition to the illustrated mounting screw 6, it is also possible to use a structure in which the door wheel 5 is engaged and fixed to the back plate 2 by an appropriate engagement mechanism. Back plate 2 corresponding to the mechanism
It is also assumed that an appropriate engaging portion is formed in place of the screw hole 20.

In addition, when using the door roller 5 that has a height adjustment mechanism incorporated therein in advance, the height adjustment screw 6 is not necessary. And height adjustment screw 6
If a structure such as the adjusting screw hole 22 is not provided, a cylindrical protrusion corresponding to the protrusion 21 is formed at the position of the mounting screw hole 20, and the screw hole 20 is formed in the center of the cylindrical protrusion. For example, as in the illustrated embodiment, it is possible to guide the expansion pieces 11, 11 in a parallel state during expansion movement.

<Effects> According to the mounting device of this invention configured as described above, it is interposed between the mounting hole H of the sash S and the door roller 5, and adjusts for differences in mounting dimensions and mounting structures between the two. A repair door roller of any shape and size can be attached to the existing sash S.

That is, the back plate 2 of the mounting device is provided with a door roller mounting portion such as a mounting screw hole 20, so that the door roller 5 can be mounted, and the mounting device is fixed by pressure contact with the inner wall of the mounting hole H to prevent movement. Since the expansion pieces 11, 11 on which the projections 15 are formed can be freely adjusted to expand by rotating the rotation plate 3,
Even if the dimensions of the door roller 5 and the mounting hole H do not match and direct attachment is impossible, the door roller 5 can be attached without any problems by the intervention of the mounting device of this invention.

In particular, since the rotary plate 3 is provided in the center of the expansion pieces 11, 11, and the tooth rows 13 formed on the left and right expansion pieces 11 are engaged with the engagement protrusions 32 of the rotation plate 3, the rotation plate 3 Adjust the expansion pieces 11 and 11 to open the mounting hole H.
Even if you try to close the expansion pieces 11 after fixing them to cannot be rotated. Therefore, even if vibration or impact is applied while the door roller 5 is installed and used, the expansion pieces 11,
The door wheel 5 does not move and become loose in the mounting state or fall off from the mounting hole H, and the door wheel 5 can be used in a secure mounting state, which is the same as directly fixing the door wheel 5 to the mounting hole H with screws or the like.

Further, since the expansion piece 11 only comes into contact with the mounting hole H, no special processing is required at all, and a normal mounting part such as a mounting screw hole 50 is simply formed in the door wheel 5. Therefore, the general-purpose door roller 5 can be used without any special door roller, and the installation work is extremely quick and easy.
The flexibility in terms of shape and structure is also very wide.

Furthermore, the mounting device is configured as a relatively thin frame whose overall shape is approximately U-shaped, and the door roller 5 is housed in the U-shaped interior space, so that the mounting hole H and the door roller 5 are connected to each other.
Even if it is interposed between the mounting hole H, it does not get in the way much, and it can be used satisfactorily even when the space of the mounting hole H is narrow.

As described above, it is possible to provide a mounting device which allows repair door rollers to be mounted easily and quickly and which has various practical effects.
