Description

  The present invention relates to a runner device that guides and supports a sliding door along a rail.

  The runner device slides and slides along a guide rail attached along the Kamoi, and opens and closes the sliding door along the rail. Generally, when installing a sliding door in an opening of a building, the opening On the other hand, the sliding door is finely adjusted by the runner device to smoothly open and close and adjust the distance between the sliding door and the building wall or between the sliding doors.

  Adjustment with this runner device adjusts the height of the sliding door, adjusts the vertical distance to adjust the distance to the guide rail, the distance to the sill and the floor, and adjusts the entrance / exit direction with respect to the opening and the distance between the sliding doors. There are adjustments in the front-rear direction, and in a conventionally provided runner device, adjustment in these two directions is possible.

The vertical and longitudinal adjustments are usually made on the hanging rods that support the sliding doors, and are usually based on the hanging rods hanging from the runner with wheels that slide on the rails. The sliding door is moved up and down or moved back and forth for adjustment.
This adjustment method is adopted in many runner apparatuses, and the inventions described in Patent Documents 1 and 2 are examples of the adjustment method.

Japanese Patent No. 3359296 Japanese Patent No. 3383606

The runner device of Patent Document 1 slides a guide groove 63 formed in a slider 61 of a front / rear position adjusting mechanism 6 that adjusts the guide member 3, that is, a support shaft 4 that hangs down from the runner member, that is, a hanging rod. In addition, by moving the slider 61 in the left-right direction, the support shaft 4 serving as the suspension can be moved and adjusted in the front-rear direction. On the other hand, the horizontal pin 5 to be planted on the support shaft 4 is slid in the guide groove 73 inclined in the vertical direction of the vertical position adjusting mechanism 7, and the pin 5 is moved up and down through the horizontal movement operation of the slider 71. In this structure, the support shaft 4 is moved up and down.
That is, here, the two independent sliders 61 and 71 are configured to slide together with respect to the support shaft 4, and by moving each slider 61 and 71 individually, the support shaft 4 is moved up and down. It can also be adjusted back and forth.

On the other hand, in the invention described in Patent Document 2, the vertical adjustment slider 7 is formed in the guide long hole 40 formed to be inclined with respect to the vertical direction in the flat connecting member 4 (hanging rod) hanging from the runner member 6. The horizontal pin 9 is slid and the slider 7 is moved in the left-right direction to adjust the vertical direction, while the connecting member 4 is slid in the slit hole 6A of the front-rear adjustment slider 6 to adjust the slider 6 in the front-rear direction. The front / rear position is adjusted by changing the position pressed by the screw 8.
In other words, the vertical adjustment slider 7 adjusts the vertical direction of the connecting member 4 (hanging rod) by the twisting operation of the screw 10, whereas the front / rear adjustment slider 6 loosens the front / rear adjustment screw 8 and moves the slider 6 to connect. After adjusting the position of the member 4, the screw 8 is tightened to adjust the front and back.

  These conventional runner devices adjust the vertical and front / rear position by operating a hanging rod (support shaft or connecting member). However, the runner device in Patent Document 1 is attached to the support shaft 4. On the other hand, since the guide grooves 63 and 73 of the slider 61 of the vertical position adjusting mechanism and the slider 71 of the front and rear position adjusting mechanism are configured to slide together, this adjustment is performed by the other slider when one adjustment operation is performed. A predetermined margin is provided between the slider and the other slider so that the operation is not hindered. That is, since the slider 61 and the slider 71 of each position adjusting mechanism act to adjust the movement in different directions with respect to the support shaft 4, a margin for not hindering each adjustment is guided. The grooves 63 and 73 are provided.

For this reason, the runner device of Patent Document 1 has a problem in that the support shaft 4 is glazed due to a margin portion provided in the guide grooves 63 and 73, and there is a problem that the stability during use is lacking.
On the other hand, in the runner device described in Patent Document 2, the adjustment operation of the connecting member 4 can be directly performed via the vertical adjustment slider 7 by the twisting operation of the screw 10, whereas the adjustment operation in the front-rear direction is the screw 8 The screw 8 cannot be moved by the twisting operation, and after the movement is adjusted, the front / rear adjustment slider 6 is fastened to fix the moving position. Inconvenience.

  In view of the problems in the conventional runner device described above, the present invention enables adjustment of the vertical and front-rear positions by twisting the adjustment screw, and at the same time, performs adjustment in the two directions, up and down and front and rear. It is an object of the present invention to provide an improved runner device which can be adjusted independently and without interfering with the other adjustment so that the runner device itself does not become loose during use.

  The runner device that can adjust the height and front / rear position of the sliding door by twisting the adjustment screw with a tool such as a screwdriver is easy to use and easy to adjust. If a mechanism that directly adjusts the adjustment mechanism is used to perform the adjustment, as described in Patent Document 1, in order not to be restrained by the other adjustment mechanism during one adjustment operation, the spatial margin is reduced. It is necessary to provide this, and this is unavoidable, but the present invention aims to improve this.

  Further, according to the present invention, it is possible to perform the adjustment operation in the used state so that the position can be adjusted up and down and back and forth by individually operating two adjusting screws with respect to the support shaft, that is, the hanging rod. An object of the present invention is to provide a runner device.

  In order to achieve the above-mentioned object, the present invention relates directly to the hanging member for the vertical adjustment member with respect to the hanging member hanging from the runner member that travels and moves the sliding door mainly on the wheel sliding on the rail, While adjusting the height of the sliding door by adjusting the vertical movement of the vertical adjustment member by twisting the adjustment screw, the front / rear adjustment member is related to the vertical adjustment member instead of the hanging member. By moving and adjusting the front / rear adjustment member in the front / rear direction by twisting the adjustment screw, it is moved back and forth based on the position of the up / down adjustment member and the hanging hook coupled thereto, and as a result, the sliding door is moved back and forth. There is in doing so.

  The runner device of the present invention will be described in more detail. A runner member that freely slides on a rail, a hanging rod that hangs down from the runner member, a mechanism frame body that incorporates a vertical adjustment member and a front and rear adjustment member; The interlocking member that transmits the operation of the front / rear adjustment member to the vertical adjustment member, the first adjustment screw that operates the vertical adjustment member, the second adjustment screw that operates the front / rear adjustment member, and the mechanism frame are mounted to the mounting portion of the door plate. An inclination guide groove for guiding the suspension rod up and down by sliding the shaft projecting from the suspension rod; A horizontal elongated hole that has a length in the horizontal direction and slides on a support shaft that lies horizontally in the mechanism frame and is slidably supported in the left-right direction. An inclined guide groove that is inclined in the front-rear direction is formed on the The lower part of the interlocking member is slidably connected to the inner groove, and the interlocking member is supported by a support shaft that lies horizontally in the mechanism frame so as to freely slide back and forth, and the upper part is slid onto the vertical adjustment member. The first and second adjustment screws are inserted between the front and rear adjustment members and the upper and lower adjustment members, respectively, and the respective screw shaft portions are mechanically supported on the side plates of the mechanism frame body in a freely rotating manner. It is inserted into the frame body, the vertical adjustment member is slid in the left-right direction by twisting the first adjustment screw, and the hanging rod is adjusted up and down through the inclined guide groove, and the second adjustment screw By the twisting operation, the front / rear adjustment member is slid in the left / right direction, the interlocking member sliding in the inclined guide groove of the horizontal plate portion is moved in the front / rear direction, and the vertical adjustment member to be connected is moved in the front / rear direction. Adjust the movement of the hanging rod back and forth with respect to the mechanism frame via It lies in that it has to so that.

  The runner device of the present invention is assembled to the sliding door by fitting and fixing the storage case in the notch recess formed in the upper end surface portion of the sliding door, and freely fitting and removing the storage case and the mechanism frame. In this assembling, the sliding door is installed in a suspended state by sliding the runner member provided on the upper part of the hanging rod protruding from the upper part of the storage case to the rail attached to the duck, and is run along the rail. You can open and close the sliding door.

  The first and second adjustment screws that adjust the vertical adjustment member and the front / rear adjustment member expose the head on the surface of the side plate that closes the side of the mechanism frame, and face the end surface of the sliding door. In other words, the adjustment operation can be performed in the state where the runner device of the present invention is used, and the adjustment can be made individually.

  When the first adjustment screw is twisted, the vertical adjustment member slides in the horizontal direction with the support shaft as a guide along with the rotation of the screw shaft, and the inclined guide groove moves in the horizontal direction along with this sliding. Therefore, the shaft body of the suspension rod that is slid in the inclined guide groove is forcibly moved along the inclination, whereby the suspension rod that can move only in the vertical direction moves upward or downward. Thus, the upper and lower direction, that is, the height position is changed by extending and contracting up and down with respect to the storage case.

On the other hand, when the second adjustment screw is twisted, the front / rear adjustment member that is screwed to the screw shaft rotates in the horizontal direction and slides into the inclined guide groove formed in the horizontal plate portion. The interlocking member to be guided is guided in the forward / backward tilt direction.
The interlocking member is slidably supported by a support shaft that is horizontally mounted on the mechanism frame, and is movable only in the front-rear direction. Therefore, the interlocking member is forcibly moved back and forth by the guide of the inclined guide groove. Is transmitted to the vertical adjustment member, and is further transmitted to the suspension rod that is slidably coupled to the vertical adjustment member. Will be moved to.

  That is, the vertical adjustment member is moved and adjusted in the horizontal direction by the twisting operation of the first adjustment screw, so that the suspension rod is directly moved up and down, and as a result, the mechanism frame and further the storage case are moved up and down to increase the height of the sliding door. On the other hand, when the front / rear adjustment member is moved in the horizontal direction by twisting the second adjustment screw, the interlocking member is moved in the front / rear direction via the inclined guide groove, and this movement is engaged. As a result of transmitting to the up-and-down adjusting member in the relationship, further transmitting to the hanging rod and moving the hanging rod back and forth, the mechanism frame body changes the front and back positions against this hanging rod, so the storage case At the same time, the position of the sliding door is moved in the front-rear direction, and the front-rear position is adjusted.

  By rotating the first and second adjustment screws from the above configuration, the vertical adjustment member and the front / rear adjustment member are individually operated to move and adjust the hanging rod from the runner member up and down and back and forth. At the same time, in the vertical adjustment operation of the hanging rod, the vertical adjustment member directly guides the hanging rod in the vertical direction via the inclined guide groove, whereas in the vertical adjustment operation of the hanging rod, the longitudinal adjustment member The interlocking member is slid in the inclined guide groove, the interlocking member is moved back and forth by the guide of the inclined guide groove, and the forward / backward movement is transmitted to the vertical adjustment member accordingly, and further the vertical adjustment member A vertical adjustment member with which the shaft body of the hanging rod slides because the hanging rod that slides in the back and forth is moved and adjusted so that the adjustment movement of the longitudinal adjustment member is indirectly transmitted to the vertical adjustment member through the interlocking member. Inclined guide formed on The shaft body is possible as long as a long hole that can be induced only in the vertical direction on.

  On the other hand, only the interlocking member slides in the inclined guide groove formed in the front / rear adjustment member, and when the front / rear adjustment member moves back and forth due to horizontal sliding, it moves along the inclined guide groove alone. Since the movement is unilaterally transmitted to the vertical adjustment member and not guided by the vertical adjustment member, the inclined guide groove can be guided only in the length direction of the groove. It has become a good thing.

  Therefore, according to the runner device of the present invention, the vertical adjustment member and the front / rear adjustment member are individually operated by twisting the first and second adjustment screws exposed on the side surfaces of the mechanism frame, and the hanging rod is moved up and down. In addition, the height position and the front / rear position of the sliding door hung from the rail by adjusting the movement back and forth can be freely adjusted. On the other hand, the mechanism frame is connected to the hanging rod hanging from the runner member via the vertical adjustment member, and the inclination guide is only moved along the inclination guide groove formed in the vertical adjustment member. If there is enough space between the groove and the shaft of the hanging rod that slides on it, it is possible to move up and down. Therefore, assembly without backlash is possible and adjustment can be performed with high accuracy.

Next, an embodiment illustrating a runner apparatus according to the present invention will be described. 1 is a front view with a partial cross section in use, FIG. 2 is a right side view with a partial cross section, FIG. 3 is a front view with a partial cross section before mounting, and FIG. 4 is an exploded perspective view of the main part. is there.
In the drawings, reference numeral 1 denotes a runner device according to the present invention, and reference numeral 2 denotes a sliding door supported by the runner device 1 in a suspended manner on a rail 4 attached to the head 3.

  The runner device 1 includes a runner member 6 that slides on an axle 5 on a rail 4 and that can freely travel in a length direction, a hanging rod 7 that is suspended from the runner member 6, a vertical direction and a longitudinal direction with respect to the hanging rod 7. The mechanism frame 8 that moves to adjust the height position and the front-rear position of the sliding door 2, and the vertical adjustment member that is built in the mechanism frame 8 and moves and adjusts the mechanism frame up and down with respect to the hanging rod 7. 9, the front / rear adjustment member 10 that moves back and forth, and the front / rear movement of the front / rear adjustment member 10 are transmitted to the up / down adjustment member 9 so that the position of the hanger 7 is moved back and forth through this member. The interlocking member 11 is provided.

The runner member 6 is supported by sliding portions 4 a and 4 a that rotatably support the pair of front and rear wheels 5 on the left and right sides of the bearing frame 12 and fold these wheels inward from the front and rear pieces of the rail 4. The suspension rod 7 is suspended at an intermediate position between the left and right wheels.
The hanging rod 7 has a head 7a having an enlarged diameter provided at the upper end thereof supported by a bearing frame 12 so as to freely rotate. The hanging rod 7 hangs down from this, and a shaft portion 7b below the head 7a is flattened into a flat plate. Is aimed at.

  Here, the mechanism frame 8 is composed of a base frame 8a formed in a shallow rectangular box shape and a lid frame 8b that is combined to close the opening, and one surface corresponding to the bottom of the base frame 8a is a rear plate. 13, and one surface of the lid frame 8 b is a front plate 14.

  The vertical adjustment member 9, the front / rear adjustment member 10, and the interlocking member 11 that connects these two members 9, 10 are accommodated in a mechanism frame 8 that is assembled in a bowl shape by tying the base frame 8 a and the lid frame 8 b. These will be described in detail.

As shown in FIG. 4, the vertical adjustment member 9 has front and rear plates 9a and 9b obtained by folding a metal plate into two U-shapes, and the two plates have a length in the horizontal direction symmetrically. Two horizontal elongated holes 15 and 16 are formed so as to be parallel in the vertical direction, and further inclined guides are inclined to the left and downward at intermediate positions of the horizontal elongated holes 15 and 16 formed so as to be shifted in the vertical and horizontal directions. A groove 17 is formed.
The vertical adjustment member 9 is supported by sliding the two support shafts 18 and 19 horizontally provided between the rear plate 13 and the front plate 14 of the mechanism frame 8 into the horizontal long holes 15 and 16. In addition, the shaft body 20 planted on the shaft portion 7b of the suspension rod 7 is slid into the inclined guide groove 17 so as to have a relationship with the suspension rod 7.

The horizontal long holes 15 and 16 guide the movement of the vertical adjustment member 9 in the left-right direction, and a sufficient length is prepared to make this movement free.
On the other hand, the inclined guide groove 17 is moved in the horizontal direction by moving the vertical adjustment member 9 in the horizontal direction, and the shaft body 20 that slides on the vertical guide member 17 is moved in the vertical direction. Therefore, the length between the upper end and the lower end of the guide groove 17 is the range of the vertical movement of the hanging rod 7, that is, the vertical width of the mechanism frame 8 relative to the hanging rod 7.

  The hanging rod 7 suspended from the runner member 6 penetrates the hole 21 that opens the shaft portion 7b in the upper surface plate of the base frame 8a of the mechanism frame body 8, and between the front and rear plates 9a, 9b of the vertical adjustment member 9. The shaft body 20 that is inserted into the shaft portion 7b is slid into the inclined guide groove 17, and when the vertical adjustment member 9 moves in the left-right direction, the shaft body 20 is guided to the inclination and moves upward or downward. Accordingly, the hanging rod 7 is moved up and down.

  In the figure, reference numeral 22 denotes a first adjustment screw for operating the vertical adjustment member 9. The adjusting screw 22 is rotatably held by sliding the neck portion 22b of the screw shaft 22a in a notch portion 24 formed in the side plate 23 of the base frame 8a of the mechanism frame 8 and exposed outside the side plate 23. The screw shaft 22a is rotated by rotating the head portion 22c, and the screw receiving plate 25 screwed into the screw shaft 22a is moved forward and backward in the left-right direction.

The screw receiving plate 25 is formed in a square plate shape, and engages with a notch 26 formed at the left end (in the drawing) of the vertical adjustment member 9.
The cut portion 26 is formed by cutting the upper edge portions of the front and rear plates 9a and 9b in the longitudinal direction across the front and rear direction, and the screw receiving plate 25 is fitted into the lower half portion of the plate from above. It can move freely in the front-rear direction.

  Accordingly, when a suitable tool is applied to the head 22c of the first adjustment screw 22 exposed outside the mechanism frame 8 and twisted from the above configuration, the screw receiving plate 25 screwed to the screw shaft 22a moves forward and backward. Accordingly, the vertical adjustment member 9 slides in the left-right direction using the support shafts 18 and 19 with which the horizontal elongated holes 15 and 16 slide together as a guide. Then, the inclined guide groove 17 moves to the left and right with this sliding, so that the shaft body 20 that slides on the inclined guide groove 17 follows the inclination of the guide groove 17, that is, the vertical adjustment member 9 moves to the left (FIG. 5). ), The vertical adjustment member 9 is pulled down to move it to the right (see FIG. 6), and the vertical adjustment member 9 is pushed up.

  On the other hand, the front / rear adjustment member 10 is formed by bending a metal plate piece into an L shape to provide a horizontal plate portion 10a and a screw receiving plate portion 10b. The horizontal plate portion 10a has a length direction (left and right in FIG. 5C). A guide groove 27 that is inclined in the direction) is formed, and a screw hole 29 into which the second adjustment screw 28 is screwed is formed in the screw receiving piece 10b.

  Similar to the first adjustment screw 22, the second adjustment screw 28 is formed by sliding the neck portion 28 b into a notch portion 30 formed below the notch portion 24 formed in the side plate 23 of the mechanism frame 8. While the shaft portion 28a is inserted into the mechanism frame body, the head portion 28c is exposed to the outside of the side plate 23 so that it can be freely twisted by an external operation.

  The front / rear adjustment member 10 is supported by screwing the screw shaft portion 28a of the second adjustment screw 28 into the screw hole 29 of the screw receiving piece portion 10b, while the front / rear adjustment member 10 is supported on the front and rear edges of the horizontal plate portion 10a. The projecting pieces 31 and 31 that are formed to extend are slid into slit-like guide holes 32 and 32 that are formed in the front and rear face plates 13 and 14 of the mechanism frame 8, so that the guide holes 32 and 32 are held in a horizontal position. The guide slides in the left-right direction.

  The interlocking member 11 is formed in a substantially crank shape by punching a metal plate, and is supported horizontally across the face plates 13 and 14 of the mechanism frame 8 in the through holes 33 and 33 formed in the upper portion 11a and the lower portion 11b. By sliding the shafts 34 and 34 in a penetrating manner, the shafts 34 and 34 are supported so as to be freely movable in the axial direction of the support shafts 34, that is, in the mechanism frame 8.

  The interlocking member 11 has a sliding neck portion 11c formed at the upper and lower intermediate portions, and the neck portion is slid into the inclined guide groove 27 formed in the horizontal plate portion 10a of the front-rear adjustment member 10, and this sliding member The upper and lower adjustment members 10 are connected to each other while the upper portion 11a is connected to the vertical adjustment member 9 by being inserted into and engaged with the space 35 between the front and rear plates 9a and 9b constituting the upper and lower adjustment members 9. As a result, the interlocking member 11 extends between the front / rear adjustment member 10 and the vertical adjustment member 9 so that the operation of the front / rear adjustment member 10 can be transmitted to the vertical adjustment member 9.

  To further explain the above relationship, when the second adjustment screw 28 for operating the front / rear adjustment member 10 is twisted by applying a tool such as a screwdriver to the head 28c, the second adjustment screw 28 is screwed into the screw shaft portion 28a according to the rotation direction. The screw hole 29 of the screw receiving piece portion 10b moves, and the horizontal plate portion 10a moves in the horizontal direction by the guidance of the projecting pieces 31, 31 and the guide holes 32, 32. Then, the inclined guide groove 27 of the horizontal plate portion 10a is moved along with this movement, so that the interlocking member 11 having the neck portion 11c slid thereon is forcibly moved according to the inclination direction of the guide groove 27. The position is moved in the front-rear direction.

The interlocking member 11 is supported by the support shafts 34 and can be moved in the front-rear direction. However, the interlocking member 11 cannot move in the forward / backward direction, that is, in the left-right direction according to the front-rear adjustment member 10. The interlocking member 11 that has passed through the portion 11c is guided by the inclination of the inclined guide groove 27 and moves only in the front-rear direction.
The front-rear movement causes the upper part 11a of the interlocking member 11 to engage with the space 35 of the vertical adjustment member 9 to push out one of the front and rear plates 9a, 9b from the inside. It will be moved to a direction, and the hanger 7 will be moved to the front-back direction.

The lid frame 8b forming the mechanism frame 8 is formed in a U shape by extending left and right side plates 36, 37 from the left and right edges of the front plate 14, and the right side plate 37 has the side plate 23 on the right side plate 37. Cutout portions 38 and 39 through which the first and second adjustment screws 22 and 28 are passed are formed at positions corresponding to the cutout portions 24 and 30 formed in FIG.
The lid frame 8 b is supported by bearing holes 40 and 41 that receive shaft ends of the support shafts 18 and 19 that penetrate the horizontal elongated holes 15 and 16 of the vertical adjustment member 9 and through holes 33 and 33 of the interlocking member 11. Bearing holes 42 and 43 that receive the shaft ends of the shafts 34 and 34, and a slit shape that slides the shaft end of the shaft body 20 of the hanging rod 7 that slides into the inclined guide groove 17 of the vertical adjustment member 9 and guides it in the vertical direction. The vertical guide groove 44 is formed.

  On the other hand, the base frame 8a combined with the lid frame 8b is formed in a substantially target shape with the lid frame 8b, and the left and right sides of the lid frame 8b are disposed between the side plate 23 and one side plate 45 opposed to the side plate 23. An interval for receiving the side plates 36 and 37 is provided to allow the frame bodies 8a and 8b to be laid together. At the same time, the rear plate 13 has the same support shaft 18 as that formed on the front plate 14 of the lid frame 8b. , 19 and 34 are formed symmetrically with bearing holes 40, 41, 42 and 43 that receive the shaft ends of the shaft body 20, and vertical guide grooves 44 that slide the shaft ends of the shaft body 20.

  The storage case 52 is fitted into the mounting portion 53 of the sliding door 2, and then fixed by screwing a set screw 55 through each through hole 56, and receives the mechanism frame 8 that has completed the assembly, Installation is performed.

  In the figure, reference numeral 59 denotes a screw rod for locking the mechanism frame 8 to the storage case 52, and the mechanism frame 8 passes through the notches 60 and 61 formed in the lower portions of the side plates 23 and 37 of the mechanism frame 8. The half-moon-shaped locking piece 62 attached to the support end of the shaft is engaged with a groove 63 formed by cutting into the bottom of the mechanism frame 8, and simultaneously the bottom surface of the storage case 52 The mechanism frame 8 can be attached to the storage case 52 by being hooked on the locking portion 64 provided in the portion.

  When the mechanism frame 8 is necessary and is removed from the storage case 52, the head 59a of the screw rod 59 is half-turned with a screwdriver or the like so that the locking piece 62 hooked on the locking portion 64 faces upward. Since it can be disengaged, the attached state can be released by pulling it right and left with respect to the storage case 53 (on the drawing), and the storage case 52 can be removed from the sliding door 2 by removing the set screw 55. Can do.

Since the runner device of the present invention is configured as described above, the sliding door can be smoothly moved by rotating the wheel 5 in a state where the runner member 6 is attached to the mounting portion 53 of the sliding door 2 and the runner member 6 is slid on the rail 4. 2 can be opened and closed.
When the sliding door 2 causes a trouble such as rubbing the lower end against the floor surface and hindering the opening and closing movement in this mounted state, the first adjustment screw 22 is twisted with a screwdriver, and the vertical adjustment member 9 is moved forward. When it is pulled out (to the right in the drawing) (see FIG. 6), the shaft body 20 that slides on the inclined guide groove 17 along with this movement moves toward the lower end of the guide groove. The adjustment member 9 is lifted with respect to the hanging rod 7 and the entire apparatus is pulled up to raise the sliding door 2, thereby avoiding contact with the floor surface.

At this time, the vertical adjustment member 9 moves horizontally in the horizontal direction with the horizontal long holes 15 and 16 sliding on the support shafts 18 and 19 as guides, and rises along the inclined guide groove 17.
When the sliding door 2 is lowered, the first adjusting screw 22 is rotated in the opposite direction to push the screw receiving plate 25 in the opposite direction, and the vertical adjustment member 9 is moved to the back (left side in the drawing). For example, since the shaft body 20 moves toward the upper end of the inclined guide groove 17, the shaft body 20 is also lowered with the mechanism frame body 8 (see FIG. 5), and the sliding door 2 can be lowered.

On the other hand, when the sliding door 2 suspended from the rail 4 rubs against other sliding doors whose positions are shifted back and forth or comes into contact with dust, the second adjusting screw 28 is adjusted so that the sliding door 2 can be easily positioned back and forth. They can be moved and rubbed to eliminate contact.
For example, when moving the sliding door 2 forward, if the second adjustment screw 28 is twisted and the front / rear adjustment member 10 is pushed back (to the left in the drawing), it slides into the inclined guide groove 27. Since the neck portion 11 c of the member 11 is forcibly moved rearward in the guide groove 27, the vertical adjustment member 9 slidably connected to the interlocking member 11 is rearward with the hanging rod 7. As a result, the mechanism frame body 8 moves forward with the front-rear adjustment member 10 in an inversely proportional manner (see FIG. 5C), and the sliding door 2 can be moved forward. it can.

  At this time, the front / rear adjusting member 10 is sandwiched between the front and rear face plates 8a, 8b of the mechanism frame 8 and integrated with the mechanism frame 8. However, the interlocking member 11 is structured with the support shafts 34, 34 as guides. The vertical adjustment member 9 that moves forward in the frame body 8 and that is connected to the frame 8 also moves forward using the support shafts 18 and 19 as guides. Then, the screw receiving plate 25 screwed into the first adjustment screw 22 in the forward movement of the vertical adjustment member 9 moves the notch 26 in the front-rear direction to allow the vertical adjustment member 9 to move back and forth. Therefore, the movement of the vertical adjustment member 9 adjusted and moved by the first adjustment screw 22 is not restricted.

  As described above, the runner device of the present invention moves the vertical adjustment member 9 in the left-right direction by the twisting operation of the first adjustment screw 22 and moves the hanging rod 7 up and down inside the mechanism frame 8, thereby the runner member 6. The height of the sliding door 2 can be adjusted by moving the mechanism frame body 8 up and down, while the second adjustment screw 28 is twisted to move the front-rear adjustment member 10 in the left-right direction and tilt through this movement. Since the interlocking member 11 that slides in the guide groove 27 is moved in the front-rear direction, and the vertical adjustment member 9 connected to the interlocking member 11 is moved back and forth, the mechanism frame 8 with respect to the hanging rod 7 can be moved and adjusted in the front-rear direction. In the state where the sliding door 2 is mounted, the vertical and longitudinal position adjustment with respect to the hanging rod 7 can be freely performed.

  Moreover, the vertical and forward / backward movement adjustment can be performed while the sliding door 2 is suspended and supported by the twisting operation of the first and second adjustment screws 22 and 28 exposed on the side surface of the mechanism frame 8. It will be easier to get to the most appropriate state.

  In particular, in the runner device of the present invention, only the vertical adjustment member 9 is a member directly related to the hanging rod 7 that suspends and supports the mechanism frame 8, and the long hole inclination guide formed in the vertical adjustment member 9 is used. The shaft body 20 of the suspension rod 7 is slid in the groove 17, whereby the range of movement is limited to the inside of the inclined guide groove 17, and the inclined guide groove 27 of the front-rear adjustment member 10 provided for the movement in the front-rear direction. As a result, the backlash generated by the fact that the inclined guide grooves 17 and 27 are related to the suspension rod 7 at the same time is effectively eliminated.

Therefore, according to the runner device of the present invention, it is possible to use silently without generating an abnormal noise due to rattling during use, while accurate up and down, front and rear movements are possible by operating the first and second adjustment screws. Movement adjustment is possible, and fine adjustment work can be easily performed.
