Abstract

PROBLEM TO BE SOLVED: To solve the following problem that: there are a round type roller whose outer periphery is roundly recessed inside, a flat type roller whose outer periphery is flat, and a V-shaped roller whose outer periphery is rounded outward as a travelling roller installed in a door in a top-railed double sliding door; the round type roller or the flat type roller generates noises when it travels, and meanwhile, the V-shaped roller generates less noise if a travel rail is made flat, however resulting in lack in travelling stability.SOLUTION: In a top-railed double sliding door, a V-shaped roller is installed and an opening and closing device capable of perfectly opening and closing the door when the door is opened and closed is installed to prevent the opening and closing device from deviating in a travel rail on which a long slide rail of the opening and closing device travels. This deviation prevention means is configured by forming a deviation prevention flange in the longitudinal direction with an interval by which the side rail does not contact with inner sides of both side walls of the travel rail.

Description

  The present invention relates to a traveling mechanism for an upper suspension type sliding door that can reliably and easily open and close the upper suspension type sliding door.

  In general, when installing sliding doors on joinery and furniture, two doors run in parallel to open and close. The sliding door has two grooves parallel to the upper duck and the lower sill, and doors are installed in the inner and outer grooves, respectively. Reeds that represent sliding doors in former Japanese houses have been adapted to tatami rooms by design, and have been widely used as doorways for entrances and partitions between rooms. This kite is composed of a thin wooden outer frame, a crosspiece built into the outer frame in a lattice shape, and a paper paste affixed on the crosspiece. The cocoon is placed between the ditch and the sill groove, and the cocoon is opened and closed as the lower part of the slid slides on the sill groove. However, in the kite, there was some resistance when opening and closing the kite because the slender surface at the bottom of the kite was sliding on the slender surface of the sill. Nevertheless, the bag can be opened and closed with a relatively weak force because it is made up of a thin wooden outer frame, crosspieces, and paper.

  By the way, in today's houses, it has come to adopt a Western style floor plan. Therefore, flooring is not often used for rooms, but wooden floors and resin boards are stuck on the entire floor. In this flooring room, the fence is not suitable, so instead of the fence, the whole door is made of wood, or a sliding door with glass or plastic fitted into a wooden frame is adopted.

  These wooden sliding doors are heavier than the fence, and if they are run by surface contact between the lower part of the elongated door and the sill groove, a considerably strong force is required. It is difficult for children to open and close. Therefore, with a wooden sliding door, a roller is attached to the lower part of the door so that it can be easily opened and closed, and a lower sliding door that runs on a rail laid on the sill, or a roller is attached to the upper part of the door. Many hanging-type sliding doors that run on rails laid in the Kamoi while hanging the doors have come to be adopted. Also, when a sliding door is used for a general closet or cupboard, a roller is often attached to the door in order to smoothly open and close the door.

  However, with a sliding door that can be opened and closed easily by installing a roller, the door travels too well, and when closing the door, running the door with even a slight force gained momentum. The door sometimes collided with a lateral outer frame on which the sliding door was installed and made a loud collision sound, or it was bounced back by the outer frame and the door returned a little to open. This occurred not only when the door was closed, but also when the door was opened, a loud collision sound and a return of the door occurred.

  Furthermore, with a sliding door, when the door is suddenly opened or closed, it stops in the middle of the open position (the door is fully open) or the closed position (the door is fully closed). Sometimes. Also, with a sliding door, if the door is run with a certain degree of strength when opening and closing, when a person who knows the position where the door fully opens or closes is opened and closed with the usual appropriate force, If the strength is too weak, the door may not be fully opened or closed, but may stop running halfway and become slightly open. In this sliding door, it is not preferable that the door is in a slightly opened state, but air that has been temperature-controlled by the air conditioning equipment will flow out of the door that is slightly opened. The effect of cooling and heating is reduced.

  In view of the problems with these sliding doors, even if the door is opened and closed vigorously, the momentum of the door is buffered, the door collision sound and door return are eliminated, and the door is completely moved to the closed or open position. Even if it is not, if the door is moved to a certain position with respect to the closed position or the open position, then the door can automatically move completely to the closed position or the open position. An opening / closing device (hereinafter simply referred to as an opening / closing device) has been proposed. (Patent Documents 1 to 4)

  By the way, in the switchgear, the switchgear is installed in the headquarters, and the striker for operating the switchgear is installed in the upper part of the door, and the switchgear is installed in the upper part of the door, and the strikeer for operating the switchgear is in the headquarter There is something to install.

  In the case where the opening / closing device is installed in the headquarters, the traveling rail for traveling the door cannot be installed in the headquarters. However, since the underlay-type sliding door has the traveling rail installed on the sill, the sound of the roller traveling on the traveling rail propagates further from the sill to the bottom. Therefore, in the lower type sliding door, if the floor where the door is installed is the upper floor, the sound of the roller traveling on the traveling rail will resonate to the lower floor, resulting in a noise problem. In particular, the noise problem becomes more serious in a heavy door because the sound generated by the roller traveling on the traveling rail is loud.

  On the other hand, when the opening / closing device is installed in the upper part of the door and the strike for the operation of the opening / closing device is installed in the Kamoi, it becomes an uplifting sliding door. This upper suspension type sliding door has a traveling rail installed at the lower part of the Kamoi, and a roller installed at the upper part of the door so that the roller can travel within the traveling rail. However, it does not propagate to lower floors. Therefore, it can be said that the suspended sliding door is suitable for the fittings and furniture of a recent high-rise apartment.

  Generally, as a roller used for furniture and joinery, there are a round roller, a flat roller, and a V roller.

  The round roller has a substantially semicircular recess on the outer periphery of the roller, and the traveling rail on which the round roller travels has a convex shape with a substantially semicircular cross section whose upper part matches the recess of the roller. The round roller has a feature that since the dent portion is in contact with the convex portion of the traveling rail and travels, the roller is not easily detached from the traveling rail and a stable traveling state is obtained. However, in the round roller, since the roller recess and the protruding portion of the traveling rail are in line contact, a heavy door generates noise during traveling.

  In the flat type roller, the outer peripheral portion of the roller is flat, and the running rail in contact with the flat portion is also flat. Since this flat roller is less stable than a round roller, the running rail needs long grooves to hold both sides of the roller like a Japanese-style sill. Moreover, since the flat roller is in line contact with the roller in the same manner as the round roller, a heavy door generates noise during traveling.

  The V-shaped roller has a V-shaped or arc-shaped outer peripheral portion of the roller, and the traveling rail used for the V-shaped roller has a V-shaped groove or arc shape substantially the same as the outer peripheral portion of the V-shaped roller. It is a groove. When this V-shaped roller also travels on a rail having a groove having substantially the same shape as the outer peripheral portion, the roller is less likely to be detached from the rail, so that stable travel is obtained. However, when the V-shaped roller travels on the groove rail, the roller and the rail are in line contact like the round roller and the flat roller, so that a heavy door generates noise during traveling. However, with the V-type roller, if the running rail is flat, the contact with the roller becomes point contact, so noise generation during running is less than that of the round roller or flat roller, and the round roller or Since there is less resistance when traveling compared to a flat roller, it is possible to travel lightly.

  Since patent document 1 installs an opening-and-closing apparatus in a Kamoi and installs a strike in the upper part of a door, a sliding door becomes a bottom type. The lowering type sliding door has a problem that noise propagates to the lower floor because the roller runs on the running rail installed on the sill as described above. Moreover, although patent document 4 installs an opening apparatus in the upper part of a door, it is a lowering type sliding door which installed the roller in the lower part of the door, and there also exists a problem that a noise propagates to a lower floor.

  Since Patent Documents 2 and 3 are upper suspension sliding doors in which an opening / closing device and a roller are installed at the upper part of the door, noise does not propagate to the lower floor. However, since the rollers of the upper suspension type sliding doors in Patent Documents 2 and 3 are round rollers, noises are reverberated indoors during traveling.

  The present invention is an uplifting type sliding door in which an opening / closing device is installed at the upper part of the door, and an uplifting type sliding door that provides stable traveling despite using a V-type roller as a roller. It is to provide a traveling mechanism.

  The present inventor believes that the sliding door opening and closing device is such that the long slide rail travels in the traveling rail, so that the sliding rail can be moved in a stable state in the traveling rail. The present invention has been completed by paying attention to the fact that the V-shaped roller can stably run on a flat running rail.

  The present invention relates to a traveling mechanism of an uplifting type sliding door in which a traveling rail is installed at the lower part of the head and a roller and a sliding door opening / closing device are installed at the upper part of the door. A damper case that houses the damper, a pair of hooks installed at one end of the damper case and the rod tip of the damper, a tension spring stretched between the pair of hooks, and a long sliding where the hook and the damper case slide It consists of a rail, V-shaped rollers are installed at both ends of the sliding rail, the traveling rail is a C-shaped channel shape, and a strike for operating the opening / closing device is attached to the inner surface of the traveling rail, In addition, a flat running surface for running the V-shaped roller is formed in the longitudinal direction at the lower part of both side walls of the running rail, and inside the both side walls of the running rail. Slightly above than V-type roller, moreover a driving mechanism of the upper hanging type pull differences door shake preventing flange with a gap not in contact with the sliding rail, characterized in that it is formed in the longitudinal direction.

  According to the present invention, since it is possible to prevent the long slide rail of the opening / closing device from being laterally shaken, the V-shaped roller can travel on the flat surface of the traveling rail without meandering. Therefore, in the present invention, the running of the roller running on the flat running rail becomes stable, and even if it is a heavy door, there is an excellent effect that can be opened and closed with a light force.

  As shown in FIG. 1, the traveling mechanism of the upwardly suspended sliding door according to the present invention (hereinafter simply referred to as an upwardly suspended traveling mechanism) includes an opening / closing device K, a V-shaped roller V, a traveling rail R, and a strike S. ing. The opening / closing device K is installed at one end near the door end F above the door T, and the V-shaped roller V is installed at both ends of the opening / closing device K and the door rear side B of the door T, and the traveling rail R Is installed at the bottom of Kamoi L, and the strike S is installed at the bottom of the top surface of the running rail R. In the upper suspension traveling mechanism, a guide rail G is laid on the sill C as shown in FIG. 2 so that the lower part of the door does not roll, and a long groove M carved on the lower part of the door is fitted to the guide rail.

  As shown in FIG. 5, the main part of the opening device K includes a damper 10, a damper case 20, a pair of hooks 30, and a 30 tension spring 40.

  The damper 10 projects so that the rod 12 can freely enter and exit from the rod port of the cylindrical cylinder 11. When the rod 12 is pushed into the cylinder 11, the force applied to the rod is buffered, and the rod slowly enters the cylinder. And move it. A bearing portion 13 is fixed to the tip of the rod.

  The damper case 20 has a bottom wall 21 at one end and an opening wall 22 at the other end. The cylinder 11 of the damper 10 is accommodated between the bottom wall 21 and the opening wall 22. A sliding groove 23 is formed in the lower portion of the damper case 20 in the longitudinal direction, and a bearing portion 24 is formed outside the bottom wall 21.

  The hook 30 is a pair of hooks 30 attached to the bearing portion 13 at the tip of the rod 12 and the bearing portion 24 of the bottom wall 21 of the damper case 20, but both hooks have the same symmetrical shape. One hook will be described with reference to FIG. 7, and the description of the other hook will be omitted.

  As shown in FIG. 7, the lower end of the upper surface of the hook 30 is formed with a flat surface that is lowered, and a shaft 31 is erected here, and a recess 32 is formed on the central side surface. . A portion close to the shaft 31 of the recess is an operating portion 33 that abuts against a strike described later and rotates the hook. And the part which opposes the action | operation part 33 of the recessed part 32 is the engaging part 34, This engaging part engages with a strike and moves a hook.

  On the side surface opposite to the concave portion 32 of the hook 30, a step is formed by lowering the shaft 31, and the step portion is an engaging step portion 35. The engagement step portion has a vertically elongated surface and engages with an engagement protrusion of a slide rail which will be described later. A sliding projection 36 is provided on the lower surface of the hook 30 on the opposite side of the shaft 31, and a spring locking portion 37 is formed on the lower surface of the hook 30. As shown in FIG. 7 (d), the spring locking portion is formed at a position closer to the engagement step portion 35 than the shaft 31.

  As shown in FIG. 6, both ends of the tension spring 40 are locked to the spring locking portions 37 of the hook 30. The tension spring is stretched with a spring force that still leaves a tensile force even when the damper rod is retracted to the innermost part of the cylinder. Since the spring locking portion 37 of the hook 30 that locks the tension spring 40 is closer to the engagement step portion 35 than the shaft 31, the tension spring 40 is locked to the spring locking portions 37 and 37 of the respective hooks. When the hook is pulled, the hooks 30 and 30 are urged to rotate about the shaft 31 in the direction of the engaging step 35 (arrow X direction), as shown in FIG.

  As shown in FIG. 1, the sliding rail 50 is considerably long even with respect to the wide door T. As shown in FIG. 8, the slide rail has a substantially U-shaped cross section, and screw insertion holes 52 and 52 for installing engagement protrusions are formed in the upper portion of one side wall 51. Has been. As shown in FIG. 4, two elongated block-like engagement protrusions 53, 53 are fixed to the inside of the sliding rail 50 with screws in the screw insertion hole portion. The thickness of the engagement protrusion 53 is substantially the same as the lateral width of the step in the engagement step portion 35 of the hook 30. As shown in FIG. 10, the engaging protrusion 53 is placed at a position where the damper 10, the damper case 20, the pair of hooks 30, 30, and the tension spring 40 are placed in the slide rail 50 and the rod of the damper 10. This is a position where the pair of hooks 30, 30 can be engaged with the two engagement step portions 35, 35 when 12 is extended to the maximum length.

  As shown in FIG. 8, a bent side 55 is formed on the other side wall 54 of the sliding rail 50 toward the inside in the longitudinal direction. The space between the lower surface of the bent side and the bottom surface 56 of the sliding rail 50 is slightly wider than the height of the damper case 20, that is, the space at which the damper case 20 can easily slide between them. Even if it is about to move upward in the sliding rail 50, the damper case 20 is restrained by the lower surface of the bent side 55 and restrains it from moving upward.

  Further, a guide protrusion 57 is formed on the bottom surface 56 of the sliding rail 50 in the longitudinal direction. The thickness of the guide protrusion is slightly smaller than the width of the sliding groove 23 of the damper case 20 and the height thereof is substantially the same as the depth of the sliding groove 23 of the damper case 20. Accordingly, when the sliding groove 23 of the damper case is fitted to the guide protrusion 57, the damper case 20 can easily slide along the guide protrusion 57. Further, a guide groove 58 is formed between the inner lower portion of the side wall 54 of the sliding rail 50 and the guide protrusion 57, and is an interval at which the sliding protrusion 36 of the hook 30 can easily slide. .

  The guide protrusion 57 is partially formed with notches 59 at two locations. As shown in FIG. 10, the notch is formed where the sliding protrusion 36 of the hook 30 is located when the engaging step portion 35 of the hook 30 is engaged with the engaging protrusion 53. The size of the notch 59 is such a size that the sliding projection 36 of the hook 30 can easily pass through. In the embodiment, the notch is formed by drilling two holes in the guide protrusion at the notch forming portion.

  The V-type roller V used in the present invention includes a hanging V-type roller 60 and a holding V-type roller 61. As shown in FIG. 12, the suspension V-shaped roller 60 has a total of four rollers 63..., Which are rotatably mounted on each side of the body 62 having a U-shaped cross section. An embedding block 65 is attached to a substantially central lower portion of the main body 62 via a connecting body 64. The connecting body 64 is attached near the end of the embedding block 65, and a part of the main body 62 projects outward from the embedding block 65. Screw insertion holes 66 and 66 are formed in the portion protruding outward. Two sets of the V-shaped roller 60 for suspension are used, and are attached and fixed to the upper part of the door front side F and the upper part of the door rear side B of the door T, respectively. As shown in FIG. 1, the suspension V-shaped roller 60 is attached to the door T by embedding an embedding block 65 in embedding grooves 67 and 67 carved at both upper ends of the door T. The hanging V-shaped roller 60 attached to the door end side F is connected to one end of the slide rail 50 of the opening / closing device K by a joint 68 by inserting a screw into the screw insertion hole 66.

  As shown in FIG. 13, the holding V-shaped roller 61 has one roller 71, 71 rotatably attached to each side of an inclined portion 70 bent obliquely upward from one end of a flat main body 69. . Two screw insertion holes 72 are formed in the main body 69, and screws are inserted into the screw insertion holes and connected to the other end of the slide rail 50.

  As shown in FIG. 14, the strike S is formed with an engaging protrusion 74 having a substantially semi-elliptical cross section on the center side of a rectangular main body 73, and mounting holes 75, 75 are provided at two locations on the main body. It has been drilled. The strike attachment position is a position suitable for weakening the momentum of the door while the door is running from the standby state to reach the open position or the closed position.

  As shown in FIG. 15, the traveling rail R has a C-shaped channel shape, and folded sides 77 and 77 are formed in the longitudinal direction inside the lower portions of the side walls 76 and 76. On the upper side of the folded side, flat running surfaces 78 and 78 are formed. An inclination is given from the running surface 78 to the side wall 76. The inclination is to increase the strength of the folded side even when a large force is applied to the running surface 78 by increasing the thickness of the corner. As shown in FIGS. 2 and 3, the interval between the opposed folding sides 77 and 77 is an inclined portion of the rollers 63 and 63 installed on both sides of the suspension V-type roller 60 main body 62 and the holding V-type roller 61. This is an interval at which the grounding portions of the rollers 71, 71 installed on both sides of the 70 can sufficiently ride on the traveling surface 78.

  The traveling rail R is also formed with a pair of anti-blur flanges 79 and 79 in the longitudinal direction on the inner upper portions of the side walls 76 and 76. As shown in FIG. 3, the distance between the anti-blurring flanges 79, 79 facing each other is such that it does not contact the slide rail 50 of the switchgear K. When trying to do so, blurring is prevented and the roller does not come off the running surface 78. The anti-blur flange 79 is located slightly above the rollers 63 and 72, and prevents the roller from lifting when the roller tries to lift upward.

  Further, the strike rails 80 and 80 are formed on the traveling rail R in the longitudinal direction inside the top surface. The width between the strike protrusions is substantially the same as the lateral width of the strike, and the strike is attached here. Since this traveling rail R is to be attached to a housing such as joinery, a plurality of screw insertion holes are drilled on the top surface of the traveling rail for attaching a traveling rail (not shown).

  Here, the assembly of the upper suspension traveling mechanism of the present invention will be described. FIG. 4 is an exploded perspective view of the upper suspension traveling mechanism before assembly. First, as described above, the damper 10 is accommodated in the damper case 20, and the bearing portion 13 is attached to the tip of the rod 12. Then, shafts 31, 31 erected on the pair of hooks 30, 30 are inserted into the bearing portion 24 of the damper case 20 and the bearing portion 13 attached to the tip of the rod 12, respectively. Thereafter, both end portions of the tension spring 40 are locked to the spring locking portions 37, 37 of the hooks 30, 30, respectively.

  Then, the assembly assembled as described above is inserted into the slide rail 50. At this time, first, one engaging protrusion 53 is placed at a predetermined position inside the sliding rail 50 and attached with a screw from the screw insertion hole 52 for installing the engaging protrusion. Then, the sliding protrusion 36 of the hook 30 is inserted into the guide groove 56 from the opened portion of the sliding rail 50, and the assembled groove is fitted with the sliding groove 23 of the damper case 20 to the guide protrusion 57 for sliding. Install in rail 50. Thereafter, another engaging protrusion 53 is placed at a predetermined position and fixed with a screw. And what attached the V-type roller 60 for suspension and the V-type roller 61 for holding | maintenance to the both ends of the rail 50 for sliding is attached to the upper part of a door with a screw | thread.

  In this way, the two engaging protrusions 53 and 53 are attached to the predetermined position in the sliding rail 50, and the damper case 20 in which the damper 10 is housed is installed. Thereafter, as shown in FIG. 10, the pair of hooks 30, 30 are stretched in opposite directions until the rod 12 becomes substantially the longest against the spring force of the tension spring 40, and the engagement step portions 35 of the hooks 30, 30 are stretched. , 35 are engaged with the engaging protrusions 53 of the sliding rail 50.

  In the opening / closing device, as shown in FIG. 10, when the engagement step portion 35 formed on the hook 30 is engaged with the engagement protrusion 53 and the hook is not yet engaged with the strike, The rod protrudes the longest and the tension spring has the longest and strongest spring force. This is a so-called “standby state” in which the door is neither completely open nor closed. When the door moves in the closed position direction or in the open position direction and the hook strikes the strike, the strike releases the engagement step portion 35 of the hook from the engagement protrusion 53. Then, as shown in FIG. 11, the hook is pulled by a tension spring to cause the door to run in the opening or closing direction. At this time, the door travels vigorously with the strong spring force of the tension spring, but the damper dampens this force and moves the door completely to the open position or the closed position while decelerating.

  Also, when the door is closed or opened vigorously, the strike disengages the hook engaging step 35 from the engaging protrusion 53, and the damper cushions the door to fully open the door. Position or closed position.

  Next, the traveling state of the suspension traveling mechanism according to the present invention will be described. As shown in FIG. 1, the sliding door T is in a state in which the door end side F is opened halfway. At this time, the opening / closing device K attached to the door T is installed at the tip of the rod 12 as shown in FIG. 10. The hook 35 and the hook 35 installed on the cylinder case 20 are engaged with engagement protrusions 53 and 53 installed on the slide rail 50. Then, when the door T is moved in the opening direction, that is, the door rear side B direction, the operating portion 33 of the hook 30 hits the strike S attached to the traveling rail R, and the hook is detached from the engaging protrusion 53 and the hook engaging portion. 35 engages the strike S. Then, since the hook 30 is pulled by the tension spring 40, the door T to which the opening / closing device is attached further moves in the opening direction, that is, the door rear side B direction. This movement is performed by the traveling of the V-type roller because the V-shaped roller V connected to both sides of the opening / closing device K is on the traveling rail R, and the long slide rail 50 of the opening / closing device K is moved to the traveling rail R. Move in.

  As shown in FIGS. 2 and 3, the roller 63 of the suspension V-shaped roller 60 connected to the opening / closing device has a grounded portion of the roller on a flat running surface 78 of the roller 63. At this time, since the flat running surface and the ground contact portion of the roller are substantially in point contact, the generation of noise is extremely small and the vehicle can be run with a light force. Although the V-type roller is very unstable on a flat surface, both upper sides of the sliding rail 50 of the switchgear K connecting the roller 63 of the hanging V-type roller 60 and the holding V-type roller 61 are used. Since the anti-blurring flanges 79 are formed inside the both side walls of the traveling rail, the long sliding rail 50 moving in the traveling rail is restrained from lateral blur by the anti-blurring flange. And stable running. Further, since the anti-blur flange is formed slightly above the upper part of the roller 63 of the suspension V-type roller 60 and the holding V-type roller 61, the movement of the roller is restricted even if it moves upward. And stable running.

Industrial application fields

  Needless to say, the present invention is not limited to a closet, a room partition, and furniture, but can be adopted anywhere as long as two doors are drawn apart.
