Japanese Utility Model Publication No.57-2966 JP 2005-325646 A Japanese Patent No. 3740661

As described above, the conventional double-adjustment type control wheel employs a structure that engages the guide groove of the operation member with the shaft located in the middle in the front-rear direction between the front and rear wheels of the support member. Since a stepped shaft is used, the processing cost of this shaft increases.
In addition, since the shaft in the middle in the front-rear direction between the front and rear wheels extends in the left-right direction and penetrates the support member, the distance between the front and rear wheels cannot be reduced as in Patent Documents 1 and 3. Because the length of the support member in the front-rear direction is increased (see FIG. 1 of Patent Document 1 and FIGS. 1, 2, and 6 of Patent Document 3), or the shaft is shifted upward as in Patent Document 2. In this case, since the length of the support member in the vertical direction is long (see FIG. 1 of Patent Document 2), the overall dimensions are large.

  Therefore, in view of the above-described situation, the present invention intends to solve the problem by providing a double-adjustment type door pulley that can be configured more simply and compactly and can be reduced in cost.

In order to solve the above-described problem, the double-adjusting door pulley according to the present invention operates the support member that supports the front and rear wheels along the rail of the lower frame with the operation member in the pull-type fitting, and prevents the wheel from being obstructed. A double-adjustment type adjustment wheel equipped with a height adjustment mechanism for adjusting the height and attached to the lower arm of a shoji, wherein an annular portion protruding outward in the left-right direction is formed on the left and right side walls of the support member. The annular portion is engaged with a guide inclined elongated hole that is formed on the left and right side walls of the frame body that is the operation member positioned on the left and right sides of the left and right side walls of the support member and that is inclined upward or backward. It is characterized by becoming.
According to such a configuration, the annular portion protruding from the left and right side walls of the support member to the outside in the left and right direction instead of the shaft penetrating the support member in the left and right direction is engaged with the inclined long hole for guide of the frame body as the operation member. Since there is no shaft penetrating the support member in the left-right direction between the front and rear wheels, there is no need to consider interference between the shaft and the wheels, and the front and rear wheels can be moved without shifting the annular portion upward. Since the interval can be narrowed, the size of the support member and the size of the operation member can be reduced, and the overall shape of the double-adjusting adjustable door wheel becomes compact.
Therefore, it is possible to reduce the cost of the double-adjustment type adjustment cart with a simple and compact configuration.

Further, in order to solve the above-mentioned problem, the double-adjustment type control wheel according to the present invention is a height that adjusts the height of the supporting member that supports the front and rear wheels along the rail of the lower frame with respect to the shoji in the pull-type fitting. A double-adjustment type adjustment wheel provided with an adjusting mechanism and attached to the lower arm of the shoji, and is attached to the lower arm, and upper and lower guide holes extending substantially upward from the lower edge are formed in the left and right side walls. The outer frame and the left and right side walls of the outer frame are located on the inner side in the left-right direction, supported so as to be swingable about the left-right axis at the front end or the rear end of the outer frame, and approach the left-right axis from the lower edge. In accordance with the above, an inclined frame for guide that is inclined upward is formed on the left and right side walls, and an annular portion is formed on the left and right side walls that is located inside the left and right side walls of the inner frame and protrudes outward in the left and right direction. , The guide upper and lower elongated holes and the guide inclined length And a support member that engages the annular portion with a screw hole formed in an upper portion of the front wall or the rear wall near the left-right axis of the outer frame, and the tip of the support member abuts the inner frame. And an adjusting screw in contact therewith.
According to such a configuration, the annular portion protruding from the left and right side walls of the support member to the outside in the left and right direction is substituted for the shaft penetrating the support member in the left and right direction. Since there is no shaft penetrating the support member in the left-right direction between the front and rear wheels, there is no need to consider interference between the shaft and the wheel, and the annular portion is shifted upward. Since the distance between the front and rear wheels can be narrowed without any problem, the dimensions of the support member and the dimensions of the outer frame and the inner frame can be reduced, and the overall shape of the double-adjusting adjustable door wheel becomes compact.
Therefore, it is possible to reduce the cost of the double-adjustment type adjustment cart with a simple and compact configuration.

Here, it is preferable that the annular portion of the support member is formed at a position offset from the center between the front and rear wheels toward the left and right axis.
According to such a configuration, since the annular portion is offset to the left and right axis side (adjustment screw side) at the lower part of the front end or rear end of the outer frame, the inner frame is rotated around the left and right axis by the adjustment screw during height adjustment. The moment of the force applied to the adjusting screw when swinging is reduced.
Therefore, since the force acting in the axial direction of the adjustment screw during height adjustment is reduced, the operation torque of the adjustment screw is reduced, so that the operability during height adjustment can be improved.
In addition, since the annular portion is offset to the left and right axis side (adjustment screw side) with respect to the support member and the wheel, the length of the inner frame in the front-rear direction can be shortened. Cost savings can be further reduced by cost savings.

The annular portion is preferably formed by burring.
According to such a configuration, the annular portion protruding from the left and right side walls of the support member to the outside in the left-right direction can be formed integrally with the support member by burring, which is a sheet metal process, thereby further reducing the cost. it can.

  As described above, according to the double-adjustment type control wheel according to the present invention, the shaft penetrating the support member in the left-right direction is replaced by the annular portion that protrudes outward in the left-right direction from the left and right side walls of the support member. Further, since it is not necessary to consider the interference between the shaft and the wheel and the distance between the front and rear wheels can be reduced, it is possible to achieve a remarkable effect that a simple and compact configuration can be achieved and the cost can be reduced.

It is a waste.
In the present specification, the direction indicated by the arrow F in the figure along which the shoji moves along the rail is defined as the front, the left and right are directed forward, and the view seen from the left is the front view.

As shown in FIG. 1 and FIG. 2, the double-adjustment type door pulley 1 according to the embodiment of the present invention includes front and rear wheels 5 along a rail C of a lower frame B in a pull-type fitting A such as a sliding sash. , 5 is operated by a frame body (inner frame 3) which is an operation member to adjust the height of the wheels 5, 5 with respect to the shoji D. Used by attaching to the front and rear ends of the lower arm E of D.
Further, as shown in FIG. 3, the front and rear wheels 5 and 5 are attached to the support member 2 via front and rear axles 5A and 5A fitted in the front and rear through holes 2a and 2a and 2b and 2b of the support member 2, respectively. The circumferential grooves 5a and 5a formed on the entire circumference of the wheels 5 and 5 are engaged with the rail C of the lower frame B (see FIG. 1).

  Here, the double-adjustment type adjustment pulley 1 shown in FIGS. 2 to 4 shows an adjustment screw 11 that is attached to the front end portion of the lower edge E of the shoji D shown in FIG. However, when attaching to the rear end of the lower heel E of the shoji D, the same double adjustment door 1 with the adjusting screw 11 facing backward (inverted 180 ° around the vertical axis) is used. Therefore, in the following description, the double-adjustment door 1 attached to the front end of the lower arm E of the shoji D will be described.

  As shown in FIG. 1 to FIG. 3, the double-adjustment adjustable wheelchair 1 is attached to the lower arm E of the shoji D, and the guide upper and lower elongated holes 9 and 9 extending substantially upward from the lower edge are provided on the left and right side walls 4A and 4A. The outer frame 4 and the left and right side walls 4A, 4A of the outer frame 4 are formed on the inner side in the left-right direction and supported so as to be swingable about the left-right axis H at the lower front end of the outer frame 4. Inclined slots 8 and 8 that are inclined upward (inclined forward) as approaching H are formed on the inner frame 3 formed on the left and right side walls 3A and 3A, and on the inner side in the left and right direction of the left and right side walls 3A and 3A of the inner frame 3. Annular portions 6 and 6 that are located and project outward in the left-right direction are formed on the left and right side walls 2A and 2A, and the annular portions 6 and 6 are engaged with the guide upper and lower elongated holes 9 and 9 and the guide inclined elongated holes 8 and 8, The support member 2 and the front and rear screw holes 4a formed in the upper part of the front wall 4B of the outer frame 4 With threaded portion 11a is screwed, consisting of adjusting screw 11 to distal end 11A is its rear end abuts against the front wall 3B of the inner frame 3.

Here, the left and right side walls 2A, 2A of the support member 2 are plate-shaped, and the lower ends of the side walls 2A, 2A are connected and integrated by a plate-shaped connecting member. Since the annular portions 6 and 6 projecting outward in the left-right direction do not interfere with the wheels 5 and 5 inside the left and right side walls 2A and 2A and can be provided at any position, for example, in this embodiment, the front and rear wheels It is formed at a position offset to the front side of the center between 5 and 5, that is, to the left and right axis H (adjustment screw 11) side.
The upper surfaces of the annular portions 6 and 6 of the support member 2 are in contact with the lower surfaces of the left and right side walls 3A and 3A of the inner frame 3 forming the upper edge of the inclined guide holes 8 and 8, respectively. The positional relationship between the annular portions 6 and 6 of the member 2 and the inclined guide holes 8 and 8 of the inner frame 3 is kept constant.

As shown in FIGS. 2 to 4, notches 10 and 10 are formed upward from the lower edge at the lower front ends of the left and right side walls 4 </ b> A and 4 </ b> A of the outer frame 4. Since the annular portions 7, 7 formed on the lower front end of the left and right side walls 3 A, 3 A of the inner frame 3 and projecting outward in the left-right direction are engaged, the inner frame 3 is in the left-right direction of the lower front end of the outer frame 4 as described above. It is supported so as to be swingable around the axis H.
Here, the annular portions 6 and 6 projecting from the left and right side walls 2A and 2A of the support member 2 outward in the left and right direction are formed integrally with the support member 2 by burring, and are laterally outward from the left and right side walls 3A and 3A of the inner frame 3. The annular portions 7 and 7 projecting to the left are formed integrally with the inner frame 3 by burring.
As described above, since the annular portions 6 and 6 and the annular portions 7 and 7 are integrally formed with the support member 2 and the inner frame 3 by burring which is a sheet metal processing, the cost is reduced by reducing the processing cost and the number of parts. can do.

Further, as shown in FIGS. 2 and 3, at least one of the left and right side walls 3A, 3A of the inner frame 3 has a convex portion 3a protruding outward in the left-right direction, and the outer frame 4 at a position corresponding to the convex portion 3a. An opening 4b is formed in at least one of the left and right side walls 4A and 4A. In the assembled state shown in FIG. 2, the protrusion 3a of the inner frame 3 protrudes into the opening 4b of the outer frame 4. Therefore, when attaching the shoji D to the rail C (lower frame B) or removing the shoji D from the rail C (lower frame B), the inner frame 3 does not fall from the outer frame 2.
Further, as shown in FIG. 2, it is overlapped with the annular portion 6 of the support member 2 that engages both the guide elongated slot 8 of the inner frame 3 and the guide upper and lower slot 9 of the outer frame 4. The lower portions of the annular portions 6 of the long holes 8 and 9 are smaller than the diameter of the annular portion 6, that is, the inner wall portion on the front side of the inclined inclined hole 8 for guide and the rear side of the upper and lower elongated holes 9 for guide. Since the inner wall portion restricts the downward movement of the annular portion 6, the support member 2 does not fall from the inner frame 3.
In addition, as described above, the positional relationship between the annular portion 6 of the support member 2 and the guide inclined long hole 8 of the inner frame 3 is maintained in a constant state and is shown in FIG. Only when the shoji D is in a high state, the annular portion 6 and the lower portion of the inner wall portion on the rear side of the guide upper / lower elongated hole 9 for preventing the fall are slid. Therefore, the reliability of the above-described fall prevention function can be maintained over a long period of time.

Next, with reference to FIG.1 and FIG.2, the height adjustment with respect to the shoji D of the wheels 5 and 5 is demonstrated.
2A, the adjustment screw 11 is operated from the state in which the wheels 5 and 5 are in a high position with respect to the shoji D (the shoji D is low), and the front wall 3B of the inner frame 3 is moved backward by the tip 11A of the adjusting screw 11. 2B, when the inner frame 3 as the operating member is swung downward (clockwise as viewed from the left) around the left-right axis H as shown in FIG. Since the support member 2 in which the annular portions 6 and 6 are engaged with the inclined long holes 8 and 8 and the guide upper and lower long holes 9 and 9 of the outer frame 4 moves downward, the wheel supported by the support member 2 5 and 5 also move downward.
Therefore, the state shown in FIG. 2B is a state where the positions of the wheels 5 and 5 relative to the shoji D are lower than the state shown in FIG. 2A (the shoji D is high).
Further, when the adjustment screw 11 is operated from a state where the positions of the wheels 5 and 5 with respect to the shoji D shown in FIG. 2B are low (the shoji D is high) and the tip 11A of the adjusting screw 11 is moved forward, the shoji Due to the weight of D, the front wall 3B of the inner frame 3 is in contact with the tip 11A of the adjustment screw 11, and the inner frame 3 swings upward about the left and right axis H (counterclockwise when viewed from the left). 2 (a) returns to a state in which the positions of the wheels 5, 5 with respect to the shoji D are high (the shoji D is low).

According to the configuration of the double-adjustment type control wheel 1 as described above, the annular portion 6 that protrudes outward in the left-right direction from the left and right side walls 2A, 2A of the support member 2 instead of the shaft penetrating the support member 2 in the left-right direction. 6 is engaged with the guide upper and lower elongated holes 9 and 9 of the outer frame 4 and the guide inclined elongated holes 8 and 8 of the inner frame 3, and the support member 2 is moved in the left-right direction between the front and rear wheels 5 and 5. Since there is no penetrating shaft, there is no need to consider interference between the shaft and the wheels 5 and 5, and the distance between the front and rear wheels 5 and 5 can be reduced without shifting the annular portions 6 and 6 upward. The dimensions of the support member 2 and the dimensions of the outer frame 4 and the inner frame 3 can be reduced, and the overall shape of the double-adjusting adjustable door wheel 1 becomes compact.
Therefore, the cost reduction of the double-adjustment type adjustment cart 1 can be achieved with a simple and compact configuration.
In addition, since it is not necessary to shift the annular portions 6 and 6 largely upward unlike the shaft in the configuration using the conventional shaft in order to narrow the distance between the front and rear wheels 5 and 5, the guide frame of the outer frame 4 is vertically long. Since it is not necessary to increase the length of the holes 9, 9, the length of the guide upper and lower elongated holes 9, 9 (depth of the notch) can be shortened as compared with the configuration using the conventional shaft.
Therefore, the lowering of the rigidity of the outer frame 4 due to the formation of the guide upper and lower elongated holes 9 and 9 can be suppressed, and the reinforcement around the elongated holes 9 and 9 based on the lowering of the rigidity becomes unnecessary. Smaller and lighter can be achieved.

Further, the annular portions 6 and 6 projecting outward in the left and right direction from the left and right side walls 2A and 2A of the support member 2 are arranged on the front side of the center between the front and rear wheels 5 and 5, that is, the left and right axis at the lower front end of the outer frame 4. Since it is formed at a position offset to the H side (adjustment screw 11 side), the force applied to the adjustment screw 11 when the inner frame 3 is swung around the left-right axis H by the adjustment screw 11 during the height adjustment described above. The moment becomes smaller.
Accordingly, since the force acting in the axial direction (front-rear direction) of the adjusting screw 11 during height adjustment is reduced, the operating torque of the adjusting screw 11 is reduced, and thus the operability during height adjustment is improved. Can do.
In addition, since the annular portions 6 and 6 of the support member 2 are offset to the left and right axis H side (adjustment screw 11 side) with respect to the support member 2 and the wheels 5 and 5, the front and rear direction of the inner frame 3. Since the length can be shortened, the cost can be further reduced by saving the material cost and the processing cost.

In the above description, the annular portions 6 and 6 projecting outward from the left and right side walls 2A and 2A of the support member 2 and the annular portions 7 and 7 projecting outward from the left and right side walls 3A and 3A of the inner frame 3 are described. Although the configuration in which the support member 2 and the inner frame 3 are integrally formed by burring is shown, the present invention is not limited to such a configuration, and the annular portions 6 and 6 and the annular portions 7 and 7 are supported by the support member. 2 and the inner frame 3 may be attached separately by welding or the like.
Further, the annular portions 6 and 6 only need to have outer peripheral surfaces formed so as to engage with the guide inclined long holes 8 and 8 of the inner frame 3 and the guide upper and lower long holes 9 and 9 of the outer frame 4. Since it is only necessary for the annular portions 7 and 7 to have outer peripheral surfaces formed so as to engage with the cutout portions 10 and 10 of the outer frame 4, the annular portions 6, 6 and 7, 7 are only annular ones. Alternatively, a cylindrical shape or the like may be used.
