Description

  TECHNICAL FIELD The present invention relates to a door panel support device applied to folding doors and sliding doors, and more particularly to a support device in which a runner restricting tool is configured using a runner body.

  It is known in Patent Document 1 that a runner restricting tool is configured using the runner body. The runner restricting tool there is composed of an elastically deformable capturing tool fixed to the end of the guide rail and a connecting body provided on the runner body. When the runner body is moved to the rail end side, the coupling body is engaged and captured by the capturing tool, so that the door panel can be held and fixed in a state in which the door panel is restricted. When necessary, the door panel can be opened by separating the connector against the elasticity of the catching tool.

  In the support device of the present invention, a runner restricting tool is provided between the upper wall of the guide rail and the runner body, and this type of runner restricting tool is known (see Patent Document 2). There, a stopper fitting with a pair of elastic arms is fixed to the upper wall of the guide rail with screws, and the runner roller is held downward by holding the runner roller downward with a pair of elastic arms. It is fixed.

  In the present invention, a height adjusting mechanism is incorporated in the runner main body, and this type of runner structure is known in Patent Document 3. There, a female screw body is screwed into a runner shaft that suspends the door panel, and the runner shaft can be adjusted up and down by rotating the female screw body via a pair of bevel gears.

JP-A-11-22291 (paragraph number 0026, FIG. 1) Japanese Utility Model Publication No. 8-7008 (paragraph number 0002, FIG. 8) JP 2001-27072 A (paragraph number 0040, FIG. 1)

  According to the runner restricting tool of Patent Document 1, since the catching tool and the coupling body are elastically engaged to restrict the door panel from opening, the door panel is opened simply by releasing the engagement state between the catching tool and the joining body. Can be operated. However, since the catching tool is fixed to the inner end of the guide rail in a state of facing the runner body, it is necessary to secure a space for placing the catching tool on the side end of the guide rail. The lateral distance between the side surface and the runner shaft must be large, causing the following problems.

  For example, when supporting a pair of folding door panels with a pair of runners, it is inevitable that the side edge of the folded door panel protrudes to either the front or back of the guide rail, and the opening surface of the closet is opened and closed with the folding door. In some cases, it is necessary to secure a space in the closet that moves with the side edge of the door panel protruding. If the width of the door panel is reduced in order to avoid the side edges of the door panel from protruding, a gap is formed between the opening frame and the door panel, and a shielding structure for concealing this gap is provided on the opening frame side. There is a need.

  In that respect, the runner restricting tool of Patent Document 2 fixes the stopper fitting to the inner surface of the upper wall of the guide rail, so that the runner body can be held and fixed at the side end position of the guide rail, and there is a gap between the opening frame and the door panel. Does not occur. If necessary, the door panel can be held and fixed at a required position in the middle of opening by fixing the stopper fitting in the middle of the guide rail. However, since the roller that rolls on the rail is held downward by a stopper fitting to restrict the movement of the runner body, the runner body easily swings in the opening and closing direction when the door panel is opened and closed.

  Therefore, for example, when the door panel is suddenly opened and closed, the runner body may come out of the stopper fitting. In addition, when the runner body applied to the folding door is held and fixed by the stopper fitting, the runner body swings when the panel pair is opened and closed, so the panel pair cannot be opened and closed smoothly. During repeated opening and closing, the stopper fitting is deformed, and the force to hold and hold the roller tends to decrease gradually, and the reliability during long-term use is lacking.

  The purpose of the present invention is to reliably restrict the movement of the runner body at the side end position of the guide rail, or to release the movement restriction and to open the door panel, and if necessary, temporarily fix the door panel at any open position It is providing the support apparatus of a door panel provided with the runner control tool which can be performed.

  An object of the present invention is to provide a door panel support device in which a height adjusting mechanism and a runner restricting tool are incorporated in a runner body, and the height of the door panel can be adjusted on the runner body side.

  The purpose of the present invention is to adjust the opening restricting force of the runner restrictor at the construction site to optimize it, and even after the construction, the opening restricting force can be adjusted. Therefore, when the door panel is fully opened and when it is partially opened In any case, it is an object of the present invention to provide a door panel support device that can easily open and close the door panel or can be securely held and fixed in a closed state.

The door panel support device of the present invention is provided between the mounting portion 11 attached to the door panels P1 and P2, the runner main body 10 guided by the guide rail 2, and between the mounting portion 11 and the runner main body 10. And a runner shaft 12 that suspends the door panels P1 and P2 via the mounting portion 11. Between the runner main body 10 and the guide rail 2, a runner restricting tool for restricting the movement of the runner main body 10 is provided. The runner restricting tool includes a rectangular restricting base 48 fixed to the inner surface of the upper wall of the guide rail 2 and an elastically deformable restricting arm 49 integrally provided on the upper surface of the body 20 of the runner body 10. The restriction arm 49 is formed of a cantilevered arm extending from the upper surface of the body 20, and an engagement piece 55 projects from the upper surface of the distal end of the arm. A spring 50 that pushes up and biases the restriction arm 49 is disposed below the restriction arm 49. The upper end of the engagement piece 55 of the restriction arm 49 is not in contact with the inner surface of the upper wall of the guide rail 2. Receiving surfaces 53 and 54 for guiding the engagement pieces 55 of the restricting arm 49 to ride on the restricting base 48 are formed on both side surfaces of the restricting base 48 in the transition direction of the runner body 10.
The restriction arm 49 is elastically deformed downward against the compressive deformation force of the spring 50 and the elastic restoring force of the restriction arm 49 itself. When the door panels P1 and P2 are closed, the engaging piece 55 of the restricting arm 49 that gets over the restricting base 48 is received by the receiving surface 53, so that the runner main body 10 is attached to the guide rail 2. The movement is restricted at the end .

A height adjusting mechanism that adjusts the height of the door panels P1 and P2 via the runner shaft 12 is incorporated in the runner body 10. The height adjustment mechanism includes an adjustment lever 24 that is pivotally supported on the body 20 via a support shaft 21, a female screw body 25 that is provided on the adjustment lever 24, and one end that is rotatable about the body 20. have been supported, and a adjusting screw 26 operated to swing the control lever 24 via the female screw member 25, the operation head 31 of the adjusting screw 26 is that not facing the outer surface below the runner body 10.

A regulation arm 49, between the spring adjusting screw 51 is screwed into the body 20, there is disposed a spring 50 which urges the push-up regulation arm 49, to adjust the biasing force of the spring adjusting screw 51 Debane 50 Te, the engagement piece 55 of the regulation arm 49 Ru can be to be able to change the overcoming resistance of time to overcome the regulatory base 48.

Receiving surfaces 53 and 54 are formed on both side surfaces of the restricting base 48 in the transition direction of the runner body 10 so as to ride on and guide the engaging pieces 55 of the restricting arm 49, and the door panels P1 and P2 are closed. in the state, the inclination angle of the side of the receiving surface 53 for receiving the engagement piece 55, Ru can set greatly as compared with the inclination angle of the other receiving surface 54.

  In the present invention, the runner restricting tool in the door panel support device includes a restriction base 48 fixed to the inner surface of the upper wall of the guide rail 2, an elastically deformable restriction arm 49 provided on the upper surface of the body 20 of the runner body 10, and the like. The engaging piece 55 of the restricting arm 49 can be received by the restricting base 48. Therefore, according to the support device of the present invention, the movement of the runner body 10 can be surely restricted at the side end position of the guide rail 2, or the movement restriction can be released and the door panels P1 and P2 can be opened, and the guide can be guided as necessary. By providing the restriction base 48 in the middle of the rail 2, the door panels P1 and P2 can be temporarily fixed at a predetermined open position.

Since the movement of the runner body 10 is restricted at the side end position of the guide rail 2, it is possible to eliminate the occurrence of a large gap between the opening frame 1 and the door panel P1 when the door panels P1 and P2 are closed. This is advantageous in that the shielding structure for concealing the gap required in the above can be omitted. Further, for example, when the pair of runners 6 and 6 supports the folding door panel pair P, it is possible to eliminate the side edges of the folded door panels P1 and P2 from protruding greatly to either the front or rear of the guide rail 2, so that the closet the opening surface in case that open and close at Orito, Ru mower advantage of effectively utilizing the space in the closet.

According to the support device in which the height adjustment mechanism is incorporated in the runner body 10 so that the height adjustment of the door panels P1 and P2 can be performed on the runner body 10 side, the height adjustment mechanism is provided on the mounting portion 11 side. Since there is no need, the structure of the mounting portion 11 can be simplified correspondingly, or a structure for exhibiting a new function other than the adjustment mechanism can be added to the mounting portion 11, and the design of the mounting portion 11 can be freely performed. The degree can be expanded. The height adjustment mechanism is configured by the adjustment lever 24, the female screw body 25, the adjustment screw 26 that swings the adjustment lever 24, and the like, and these members are incorporated into the runner body 10, so that the height adjustment mechanism is added. By doing so, it is possible to prevent the runner body 10 from becoming large, and the guide rail 2 can be made compact accordingly. When the operation head 31 of the adjustment screw 26 is arranged so as to face the lower outer surface of the runner body 10, the adjustment screw 26 can be easily adjusted even though the runner body 10 is located inside the guide rail 2. Ru can be easily performed in such a posture.

The restriction arm 49 is formed of a cantilevered arm, and an engagement piece 55 is provided on the upper surface of the tip, and then the spring 50 is disposed between the restriction arm 49 and the spring adjustment screw 51 screwed into the body 20. Thus, according to the type of support device that pushes up and biases the regulating arm 49, the tension of the spring 50 is adjusted by tightening and loosening the spring adjusting screw 51, so that the engagement piece 55 gets over the regulating base 48. The ride-over resistance can be changed and adjusted. Therefore, at the time of construction, the resistance over the restriction arm 49 can be adjusted to the optimum state according to the difference in the panel weight, such as the material and structure of the suspended door panels P1 and P2, and even after construction, Overcoming resistance of the restricting arm 49 can be optimized according to changes in the elastic force of the arm 49, the degree of wear of the restricting base 48 and the engaging piece 55, and the like. In other words, since the regulating force of the runner restricting tool can always be optimized, the door panels P1 and P2 can be opened and closed lightly or reliably in either case where the door panels P1 and P2 are fully opened or partially opened. supporting device that can be held stationary in the closed state Ru obtained.

Receiving surfaces 53 and 54 for climbing and guiding the engaging piece 55 of the restricting arm 49 are formed on the restricting base 48, and the receiving surface 53 on the side for receiving the engaging piece 55 in a state where the door panels P1 and P2 are closed. When the inclination angle is set to be larger than the inclination angle of the other receiving surface 54, the runner body 10 gets over the engagement piece 55 when entering and leaving the space between the restriction base 48 and the rail end. The resistance can be made different so that the runner body 10 can easily enter the previous space, but not easily from the same space. Therefore, even when the door panels P1 and P2 are suddenly opened and closed, the runner body 10 can be reliably prevented from coming out of the restriction base 48, and the runner body 10 is restricted from swinging in the opening and closing direction when the panel pair P is opened and closed. to, Ru smoothly perform the opening and closing of the panel pair P.

  The drawings show an embodiment in which the supporting device according to the present invention is applied to a folding door. The folding door shown in FIG. 2 is composed of a pair of left and right panels P, and both the panel pairs P are guided and supported by guide rails 2 and 3 disposed above and below the opening frame 1 so as to be foldable. Each panel pair P is configured by connecting adjacent edges of two door panels P1 and P2 with a hinge 4.

  A handle 5 for opening and closing the panel pair P is fixed in the vicinity of the refracting edge of the door panel P2 located at the center of the opening. The hinge 4 has a click function for maintaining the panel pair P in the unfolded state in the fully unfolded state and the semi-deployed state. A runner 6 and a brace 7 are attached to the upper and lower surfaces on both sides of each panel pair P. The runner 6 is guided by the guide rails 2 and 3 respectively.

  1 and 3, a runner 6 includes a runner body 10 that is guided by the guide rail 2, a mounting portion 11 that is mounted on the door panels P 1 and P 2, and a runner shaft that connects the runner body 10 and the mounting portion 11. 12 and so on. The attachment portion 11 includes a runner base 13 that is connected to the runner main body 10 by a runner shaft 12 so as to be relatively rotatable, and a socket 14 that is fixed to the door panels P1 and P2.

  In FIG. 2, the brace 7 is configured by housing a shaft 16 and a spring 17 that pushes and biases the shaft 16 in a case 15, and a freely rotatable roller 18 is assembled to the lower end of the shaft 16. By guiding the rotating peripheral surface of the roller 18 with the guide rail 3 embedded in the floor surface, the door panels P1 and P2 are restricted from tilting back and forth.

  The runner body 10 includes a horizontally-long block-shaped body 20 made of a plastic molded product, four rollers 22 that are arranged on the left and right sides of the front and rear surfaces of the body 20 and are rotatably supported by a roller shaft 21, and a body 20 and a height adjusting mechanism incorporated in the interior of the apparatus.

  4 and 7, the height adjustment mechanism includes an adjustment lever 24 pivotally supported by one roller shaft (support shaft) 21, a screw plate (female screw body) 25 assembled to the adjustment lever 24, An adjustment screw 26 that is screwed into the screw plate 25 to swing the adjustment lever 24, and a stop plate 27 that holds the adjustment screw 26 in a rotatable state so as to be retained. All of these components are incorporated in a recess 23 formed in the body 20 and having a cross-sectional keyhole shape whose upper surface is open, and cannot be viewed from the outside.

  5 and 7, the adjustment lever 24 is formed of a press fitting having a pair of front and rear arm walls, an operation arm 28 that supports the screw plate 25 so as to be tiltable on one side, and a runner shaft 12 on the other side. A drive arm 30 is provided to support the via.

  In order to make the adjustment operation of the adjustment screw 26 easier and easier, the entire adjustment screw 26 is inclined with respect to the vertical line, and the operation head 31 is exposed at the lower corner of the body 20. is doing. When the adjusting screw 26 is tightened or loosened to swing the adjusting lever 24 up and down, the support height of the runner shaft 12 changes, and the suspension height of the door panels P1 and P2 can be individually adjusted accordingly.

  In FIG. 6, the runner base 13 is a plastic molded product including a fitting portion 33 in which a contour line in a plan view is formed in an inverted V shape, and flanges 34 formed on both sides of the front surface of the fitting portion 33. Thus, the fitting portion 33 is integrated with the socket 14 by being fitted into the connecting recess 36 of the socket 14 and loaded.

  In order to prevent the runner base 13 attached to the connecting recess 36 from being separated, lock claws 37 are provided on the left and right of the lower portion of the flange 34, and the lock piece 38 is provided with a horizontal guide groove provided on the upper portion of the fitting portion 33. Supports slidable back and forth. The lock claw 37 engages with a retaining portion 39 formed along the front opening edge of the connecting recess 36 to prevent the fitting portion 33 from coming out. When the pair of lock claws 37 are elastically deformed in the approaching direction, the engaged state with the retaining portion 39 can be released. Reference numeral 40 denotes a check arm.

  The lock piece 38 is made of a plastic molded product having a generally trapezoidal base 42 and a U-shaped operation piece 43 projecting from the front surface of the base 42, and a pair of front and rear lock projections 44 on the oblique side of the base 42. Is protruding.

  In FIG. 3, the lock piece 38 is urged backward by a compression coil spring 45 and is received by the runner shaft 12. In this locked state, the lock piece 38 is formed on the upper surface of the lock protrusion 44 on the rear surface of the connection recess 36. By receiving the lower surfaces of the formed pair of protrusions 46, the runner base 13 is prevented from being separated from the connection recess 36. When the operation piece 43 is pulled against the spring 45, the engagement state between the lock protrusion 44 and the protrusion 46 is released, and the runner base 13 can be separated from the connection recess 36.

  In order to regulate the opening movement of the door panel P1 on the opening side end side, a runner regulating tool that regulates the movement of the runner body 10 is provided between the runner body 10 and the guide rail 2. In FIG. 4, the runner restricting tool includes a restriction base 48 fixed to the inner surface of the upper wall of the guide rail 2, a restriction arm 49 provided on the upper surface of the body 20 of the runner body 10 and elastically deformable in the vertical direction, and a restriction arm 49. A compression coil spring 50 that pushes up and biases the spring 50 and a spring adjustment screw 51 that adjusts the biasing force of the spring 50.

  The regulation base 48 is a quadrangular plastic molded product. A laterally long screw hole 52 is formed at the center of the regulation base 48, and the right and left side surfaces in the transition direction of the runner body 10 receive the engagement pieces 55 of the regulation arm 49. A pair of receiving surfaces 53 and 54 are formed. As will be described later, the runner body 10 can pass through the lower surface side of the regulation base 48 when the engagement piece 55 of the regulation arm 49 gets over the regulation base 48.

  In order to make the overcoming resistance when the engaging piece 55 gets over the regulation base 48 to the rail end side larger than the overcoming resistance when going over in the opposite direction, the inclination angle of the receiving surface 53 on the rail side end side is set to the other receiving side. It was set larger than the inclination angle of the surface 54. That is, the runner body 10 is easy to enter the space between the regulation base 48 and the rail end, but is difficult to get out of the space. Reference numeral 59 denotes a screw for fastening and fixing the regulation base 48. This screw 59 can also serve as a screw for fixing the guide rail 2.

  4 and 7, the restricting arm 49 includes a cantilevered arm formed integrally with the body 20, a triangular engagement piece 55 is provided on the top surface of the tip, and a spring receiving surface is provided on the bottom surface of the tip. A boss 56 is projected. The spring adjusting screw 51 is composed of a hexagon socket head cap screw, and is screwed into a screw hole 57 provided in the body 20 so as to face the boss 56, and the spring 50 is disposed therebetween. Therefore, when the spring adjusting screw 51 is tightened or loosened, the tension of the spring 50 is changed to a large or small value, and the overcoming resistance when the engaging piece 55 gets over the restriction base 48 can be adjusted.

  As shown in FIG. 1, in the state where the panel pair P is completely extended and the opening surface is closed, the engaging piece 55 and the receiving surface 53 are adjacent to each other in the lateral direction, and the engaging piece 55 has the restricting arm 49 at the end. Since it is received in a state where it is stretched and supported, the movement of the runner body 10 in the opening direction can be reliably regulated.

  The runner body 10 in this state is located in the space between the regulation base 48 and the rail end, and the side end surface of the door panel P1 is substantially through a slight margin with respect to the inner surface of the opening frame 1. In contact. When the panel pair P is folded from the closed state to open the opening surface, and the entire panel pair P in the folded state is moved along the guide rail 2 toward the center of the opening, the engagement piece 55 elastically deforms the regulating arm 49. The panel pair P can be fully opened because the control base 48 is overcome.

  In the support device for folding doors configured as described above, the panel pair P is suspended from the runner body 10 in the following manner. A socket 14 is assembled in advance to the door panels P1 and P2. The runner body 10 is assembled into the guide rail 2 corresponding to each panel pair P. At this time, the set of runner main bodies 10 are loaded so that the tips of the regulation arms 49 face each other, and the check arms 40 of the adjacent runner bases 13 are engaged with each other as shown in FIG. The runner base 10 is restricted from rotating around the runner shaft 12.

  Next, as shown in FIG. 8A, the panel pair P folded in half is held up and the pair of runners 13 whose rotation is restricted are sandwiched and held between the facing surfaces of the door panels P1 and P2. At this time, the height of the panel pair P is adjusted by the reference amount so that the lower half portion of the fitting portion 33 generally faces the connection recess 36.

  With this state maintained, the panel pair P is pulled forward, and the runner base 13 is dropped into the connection recess 36 of the socket 14 and engaged as shown in FIG. By the first engaging operation in the front-rear direction, the lock claw 37 is lowered and engaged with the retaining portion 39 while being elastically deformed, and the temporarily assembled state of the panel pair P and the runner base 13 can be maintained.

  In the above temporarily assembled state, when the panel pair P is pushed up, the protrusion 46 comes into contact with the lock protrusion 44 of the lock piece 38 from the lower surface side, and the lock protrusion 44 is pushed upward while moving against the urging force of the spring 45 to move upward. At the same time, the lock piece 38 is returned and operated by the spring 45 to switch to the locked posture, and the upper surface of the lock protrusion 44 receives the lower surface of the protrusion 45 to prevent the runner base 13 and the socket 14 from separating. Since a series of these suspension operations can be performed by a single operator, the folding door can be suspended quickly and easily compared to the conventional mounting structure.

  The restriction base 48 can be fixed at an arbitrary position on the upper wall of the guide rail 2. Therefore, if the restriction base 48 is fixed in the middle of the guide rail 2, the movement of the panel pair P can be restricted by receiving the engagement piece 55 of the restriction arm 49 at that position. If necessary, the two restriction bases 48 are fixed to be adjacent to each other, and the engagement pieces 55 of the adjacent runner main body 10 are simultaneously received by both restriction bases 48 so that the left and right panel pairs P and P can be freely attached to the guide rail 2. The movement can be restricted at the position.

  When adjusting the suspension height of the door panels P1 and P2, the panel pair P is folded to open the outer surface of the operation head 31 of the adjustment screw 26, and the adjustment screw 26 is rotated with an operation tool such as a screwdriver. Adjust and move the runner shaft 12 up and down. Similarly, when adjusting the resistance overcoming the restricting arm 49, after opening the lower surface space of the spring adjusting screw 51, the spring adjusting screw 51 is rotated by an operating tool such as a screwdriver, so that the compression length of the spring 50 is increased. And adjust its tension.

  If the tension of the spring 50 can be adjusted in this way, the resistance over the restriction arm 49 can be adjusted to the optimum state according to the construction situation, and the elastic force of the restriction arm 49 can be changed even after construction. Further, it can be optimized by adjusting and changing the overcoming resistance corresponding to wear of the regulation base 48 and the engagement piece 55.

  The attachment portion 11 need not have the structure described in the embodiment, and a known attachment structure can be applied. For example, it may be an attachment structure in which the runner base 13 is fitted and connected from the side to the socket 14 attached to the side end surfaces of the door panels P1 and P2. Furthermore, the attachment structure of the form which fastens and fixes the reverse L-shaped metal fitting with which the runner axis | shaft 12 was fixed to the door panels P1 and P2 directly with a screw may be sufficient.

  The female screw body 25 in the height adjustment mechanism may be formed on the adjustment lever 24 side. In that case, the adjustment screw 26 is supported by the body 20 so as to be rotatable and tiltable so that the swinging motion of the adjustment lever 24 can be absorbed on the adjustment screw 26 side. Of the receiving surfaces 53 and 54 of the regulation base 48, the receiving surface 53 on the rail end side does not need to be an inclined surface. For example, the lower edge of the regulation base 48 can be rounded to form the receiving surface 53. The support device of the present invention can also be applied to a sliding door. The support shaft can be provided separately from the roller shaft 21.
