Description

  The present invention relates to a door roller and a fitting provided in a lower case.

  Since the door wheel moves the door while supporting the weight of the door, it is easily damaged among the members constituting the door, and if it is broken, replacement may be forced. There are various types of door bodies provided with door wheels, and the size and shape of the parts to which the door wheels are attached are also various. Therefore, the wheel is equipped with a pair of left and right spread members that are spread left and right by turning the screw and press-fit the inner wall of the attachment hole such as sash so that it can be easily attached with versatility. There is known a door wheel provided in a closed door case (see, for example, Patent Document 1).

  The spreader members are provided on both sides of the wheel in a direction orthogonal to the axis of the wheel, and are formed in a square shape with a metal plate or the like, and the pair of spreader members having mutually symmetrical shapes are mutually It is coaxially axially supported in the vicinity of one end side of the and can be expanded to the left and right. Both spreading members are provided with pressing convex portions that curve and project inwards facing each other, and on the non-axially supported end side of the spreading members, the pressing convex portions by turning the screw A pressing member is provided so as to enter between the pressing members, and the pressing member enters between the pressing projections to push and spread the expanding member in the left-right direction to press against the inner wall of the mounting hole. Further, at the end on the spread side opposite to the end on the pivotal support side of both spread members, there is provided a claw portion which is formed so that the tip is pointed out and protrudes outward. The claws are pressed against the inner wall of the mounting hole so that the door wheel case is fixed at an arbitrary position of the mounting hole when the claws are expanded to the left and right.

An inner frame 91 is accommodated on the inside of the outer frame 92 so as to overlap in the view direction with a slight gap. The inner frame 91 swings by rotating the swinging screw 91d whose tip is abutted to the outer connecting portion 92b of the outer frame 92 to change the amount of protrusion of the swinging screw 91d, and the roller 8 moves to the outer frame It is configured to move up and down with respect to 92. The swinging screw 91 d is operated to correct inclination or the like when the shoji 3 is mounted on the frame 2.

  The outer frame 92 is formed longer on both sides in the longitudinal direction than the inner frame 91, and the expected position adjusting mechanism 10 and the height adjusting screw 20 are provided on the outer side of the inner frame 91 in the longitudinal direction.

  The expected position adjusting mechanism 10, as shown in FIG. 5, includes an operation screw 11 operated from below and an up and down moving member 12 having an engagement pin 12a which is vertically moved by the operation screw 11 and protrudes in the longitudinal direction. The slide plate 13 as two bidirectional projecting parts that engage with the engagement pin 12a and project in opposite directions in the viewing direction by the up and down movement of the engagement pin 12a It has a guide block 14, a slide guide block 15 for guiding the movement of the two slide members, and a joint pin 16 for joining the vertical motion guide block 14 and the slide guide block 15.

  The vertically moving member 12 is a member having an L-shaped cross section, and includes a screw plywood part 12 b disposed substantially horizontally and in which the operation screw 11 is screwed, and a vertically moving guide block 14 disposed substantially along the vertical direction. And a restricting plate portion 12c for restricting movement in the direction of prospect. The engagement pin 12a is provided on the upper end portion side of the restriction plate portion 12c so as to protrude longer on the opposite side to the screwed plywood portion 12b.

  The two slide plates 13 are flat members, and as shown in FIG. 6 and FIG. 7, long holes 13 a formed at an angle of 45 degrees with respect to the vertical direction from the center in the viewing direction in the attached state Respectively. The width of the long hole 13a is formed slightly wider than the diameter of the engagement pin 12a to be inserted. The two slide plates 13 are arranged so that the inclination directions of the long holes 13 a provided in each are different from each other and are overlapped in the longitudinal direction by using the same members with the front and back reversed.

  The slide guide block 15 has a slide groove 15a whose width in the vertical direction is slightly larger than the width in the vertical direction of the slide plate 13 and provided horizontally along the direction of prospect, and the two slide plates 13 are The long holes 13a are arranged in the slide groove 15a so as to face each other and to overlap in the longitudinal direction so that the inclined directions of the long holes 13a are different. The two slide plates 13 have substantially the same width as the width of the slide groove 15a in the direction of view, and can move horizontally along the slide groove 15a. In the present embodiment, each long hole 13a is inclined so as to overlap at the center of the slide groove 15a and to become lower outward from the center.

  The expected position adjusting mechanism 10 includes an upper and lower guide block 14 including an up and down moving member 12 in which an operation screw 11 engaged with the up and down movement is engaged with a screwed plywood part 12b, and two slide plates in a slide groove 15a. Joining with the slide guide block 15 in which the reference numeral 13 is disposed in a state in which the engagement pin 12a provided on the vertical movement member 12 is inserted into the portion where the long hole 13a overlaps at the center of the two slide plates 13 It is joined by the pin 16. At this time, the two slide plates 13 are configured not to protrude from the slide guide block 15 in the expected direction.

  When the operation screw 11 is rotated in a state in which the expected position adjustment mechanism 10 is mounted in the outer frame 92, the rotation of the operation screw 11 also lowers the engagement pin 12a together with the vertically moving member 12. At this time, since the engaging pin 12a moves while pressing the lower edge of the long hole 13a downward, the slide plate 13 is guided by the slide groove 15a so as to project from the slide guide block 15 in a prospective direction Slide. The two slide plates 13 are different from each other in the direction of inclination of the long holes 13a respectively, and therefore, the two slide plates 13 project in mutually opposite directions in the viewing direction from the state of facing each other and overlapping in the longitudinal direction. Further, since the inclination angles of the two long holes 13a are the same, the two slide plates 13 simultaneously project in the same direction in opposite directions. The door wheel 7 is positioned at the center of the lower frame 6 in the expected direction by the tips of the two projecting slide plates 13 abutting on the side 6 f forming the hollow portion 6 a almost simultaneously.

  The height adjustment screw 20 has a flat head 20a and a hollow portion 6a and a diameter slightly shorter than the distance between the opposing side portions 6f. It is screwed from above at 92b. The two height adjustment screws 20 are provided one each on both sides of the roller 8 in the longitudinal direction, and the amount of protrusion from the outer connection portion 92b by rotating, ie, the outer connection portion 92b to the head 20a tip It is possible to change the distance to. The door wheel 7 is appropriately adjusted in the amount of protrusion of the two height adjustment screws 20 and inserted into the hollow portion 6a, and the head 20a of the height adjustment screw 20 abuts on the upper surface portion 6b forming the hollow portion 6a. Thus, the height of the door 7 is determined.

  The holding screw 25 has the same shape as the height adjusting screw 20, and is screwed from below to the screwing piece 93 crimped to the outer frame 92. More specifically, the end inserted into the opening 92c formed in one of the two outer walls 92a of the outer frame 92 and inserted into the mounting hole formed in the other protrudes from the mounting hole and caulked. The holding screw 25 is screwed into the screwing piece 93. The holding screw 25 can change the amount of protrusion from the lower edge of the outer frame 92, that is, the distance from the lower edge of the outer frame 92 to the tip of the head 25a by rotating.

  In the method of mounting the door wheel 7, first, the amount of protrusion of the two height adjustment screws 20 is appropriately adjusted, and the distance between the head 20a of the height adjustment screw 20 and the head 25a of the holding screw 25 is a hollow portion In a state in which the amount of protrusion of the holding screw 25 is adjusted to be shorter than the distance between the upper surface 6b and the lower surface 6d forming 6a, it is inserted into the hollow portion 6a of the lower collar 6 of the shoji 3 which is turned upside down. At this time, the door wheel 7 is placed in contact with the upper surface portion 6b of the lower frame 6 of the shoji 3 with the head portions 20a of the two height adjustment screws 20 inverted. With the door 7 mounted on the upper surface 6b, the swing screw 91d, the operation screw 11 of the two expected position adjustment mechanisms 10, and the holding screw 25 can be operated from the notch 6e provided on the lower surface 6d. In the position where the door 7 is held, the door 7 is disposed at a position where the head 11a of the operation screw 11 and the head 25a of the holding screw 25 face the notch 6e. Here, the head portion 11 a of the operation screw 11 corresponds to the operation portion of the operation screw 11, and the head portion 25 a of the holding screw 25 corresponds to the operation portion of the holding screw 25.

  Next, the two operation screws 11 of the inserted door wheel 7 are respectively rotated by a tool such as a driver having the notch portion 6e inserted, and the two slide plates 13 are projected in the visual direction, and the tip thereof is sided It is made to abut on the part 6 f to restrict movement of the door 7 in the expected direction. Thereby, the door wheel 7 is positioned in the expected direction.

  Next, the holding screw 25 of the door 7 is rotated by a tool such as a driver inserted in the notch 6 e to increase the amount of protrusion of the holding screw 25. As a result, the head 25a of the holding screw 25 is brought into contact with the lower surface 6d provided on both sides of the notch 6e in the prospective direction, and the two height adjusting screws 20 and the holding screw 25 are further rotated. The door 7 is held by pressing the upper surface 6b and the lower surface 6d of the lower rod 6 in opposite directions.

  According to the door wheel 7 of the present embodiment, the holding screw 25 whose amount of protrusion from the outer frame 92 of the frame 9 supporting the roller 8 changes is rotated, and the upper surface 6b and the lower surface 6d of the hollow portion 6a are mutually The frame 9 is supported on the lower surface portion 6d of the hollow portion 6a because it is held by the lower rod 6 by pressing in a direction away from and being stretched between the upper surface portion 6b and the lower surface portion 6d. For this reason, even if the part which forms hollow part 6a changes, it is possible to prevent that door 7 descends. Further, the protrusion amount of the holding screw 25 from the outer frame 92 is reduced to insert the door wheel 7 into the hollow portion 6a, and the protrusion amount of the holding screw 25 is increased in the hollow portion 6a to form the hollow portion 6a. The upper surface 6b and the lower surface 6d can be easily attached by pressing them in directions away from each other. For this reason, it is possible to provide the door wheel 7 which is hard to descend from the attached position.

  In addition, since the holding screw 25 communicates the inside of the hollow portion 6a with the outside and faces the notch 6e from which the roller 8 protrudes, the holding screw 25 can be easily rotated from the notch 6e. It is possible.

  Further, since the frame 9 is provided with the expected position adjusting mechanism 10 provided with the slide plate 13 that protrudes toward both sides in the prospect direction and can change the amount of protrusion, the amount of protrusion of the two slide plates 13 By changing the distance, it is possible to change the distance between the side portion 6 f forming the hollow portion 6 a and the outer frame 92. For this reason, it is possible to easily change the position of the roller 8 in the prospecting direction, and it is possible to provide the door wheel 7 in which the adjustment of the position in the prospecting direction is easy.

  Further, by operating the operation screw 11, it is possible to project the two slide plates 13 which project in both directions toward both sides in the prospect direction by approximately the same amount. It can be easily placed in the center of the

  Further, since the head 11a of the operation screw 11 of the expected position adjustment mechanism 10 is provided on the lower surface 6d of the lower rod 6 and faces the notch 6e from which the roller 8 protrudes, the operation is performed from the notch 6e By doing this, it is possible to make the two slide plates 13 project in both directions toward both sides in the viewing direction. Further, since the operation screw 11 can be rotated from the notch 6e in the same manner as the holding screw 25, the posture of the shoji 3 is changed when operating the holding screw 25 and the operation screw 11, or the operator can It is possible to adjust more easily without moving.

  Further, since the view position adjustment mechanism 10 is disposed in a state in which the slide plates 13 formed of two plate members face each other and overlap in the longitudinal direction of the lower frame 6, the view position adjustment mechanism in the longitudinal direction of the lower frame 6 It is possible to make the width of 10 smaller. For this reason, it is possible to reduce the size in the longitudinal direction of the door 7. This makes it possible to attach the lower portion of the notch 6e to a smaller size with a smaller longitudinal dimension.

  Further, since the frame 9 can change the distance between the upper frame portion 6b forming the hollow portion 6a and the outer frame 92 by changing the amount of projection of the height adjustment screw 20, the height at which the roller 8 is supported Can easily be changed. For this reason, it is possible to provide the door wheel 7 in which the height adjustment of the support position of the shoji 3 is easy.

  Further, since the door wheel 7 can adjust the height by the height adjusting screw 20 and the position in the prospecting direction by the prospect position adjusting mechanism 10, it is possible to easily make the lower wheels different in size from each other. It is possible to adjust the position and mount it. Further, the door 7 can be inserted into the hollow portion 6a from the fore end of the lower rod 6, and the holding screw 25 can be operated from the notch 6e provided on the lower surface 6d of the lower rod 6. It is also possible to remove it from the first as it is made to hold it. Therefore, when the door 7 is damaged, it can be easily replaced.

Further, the shoji 3 equipped with the above-mentioned door wheel 7 is easy to adjust and attach the position of the door wheel 7, and it is also easy to replace it. In particular, since the door roller 7 is supported by the holding screw 25 on the lower surface 6d of the lower rod 6, the door roller 7 is lifted even when the shoji 3 is lifted when removing the shoji 3 attached in a pendulum type. Since 7 does not move downward, it is possible to remove the shoji 3 easily by reliably separating the roller 8 from the rail.
Further, with the holding screw 25 and the two height adjustment screws 20 stretched between the upper surface portion 6 b and the lower surface portion 6 d in a state where the door roller 7 is held, the holding screw 25 is in the longitudinal direction of the lower rod 6 It is located between two height adjustment screws 20. For this reason, it is possible to restrict the rotation of the door 7 in any direction about the axis along the expected direction in the lower frame 6 and hold the door 7 more reliably.

  In the above embodiment, the head 25a of the holding screw 25 and the head 20a of the height adjusting screw 20 have a circular shape, but for example, as shown in FIG. It is possible. For example, the holding screw 21 has a countersunk screw 22, an oval seat plate 23 having a countersunk hole, and a nut 24, and the nut 24 is engaged with the countersink 22 through which the countersinking hole is inserted. The seat plate 23 may be rotatably fixed to the countersunk screw 22 by tightening.

  And as shown to Fig.9 (a), when using for the width | variety of anticipation direction with the narrow width | variety 6 narrow, the long-axis side of the seat plate 23 is made to follow the longitudinal direction of the lower rod 6, As shown in FIG. 9 (b), when used for the lower rod 6 with a wide width in the prospecting direction, the long axis side of the seat plate 23 is made to intersect the longitudinal direction of the lower rod 6 Place. Since the same door wheel 7 can be attached even if it is the lower rod 6 from which a dimension mutually differs by this, versatility is improved more.

  In the above embodiment, the height of the roller 8 can be adjusted by swinging the inner frame 91 with respect to the outer frame 92 by operating a screw that appears in the vertical direction from below the lower rod 6. Although the door wheel 1 has been described as an example, the present invention is not limited to this. For example, a roller height adjusting mechanism 95 may be provided which can adjust the vertical position of the roller 8 by operating along the longitudinal direction of the lower rod 6.
