Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a runner catcher that is applied to a free folding door and captures a runner located at a side end of an opening frame. This runner catcher is provided with a gap removing function that pushes back the panel pair when fully closed to the center side of the opening surface so that adjacent panel pairs are brought into close contact with each other.
[0002]
[Prior art]
There is a free folding door in which a panel pair that can be refracted into a V-shape is used as a unit, a plurality of panel pairs are individually refracted and opened, or an arbitrary panel pair can be refracted and moved left and right along a rail. This type of free folding door is applied to, for example, a walk-in closet, and a runner located near the side edge of the opening frame of each panel pair is captured by a runner catcher, and each panel pair is placed at the center of the opening surface. It can be folded and opened. For example, an example can be seen in Japanese Utility Model Publication No. 8-7008.
[0003]
In the free folding door, the width of the opening is set to be larger than the total width of all the panel pairs because it is necessary to swing and swing the individual door panels around the runner shaft suspended from the runner. Therefore, in the closed state where all the panel pairs are expanded, a gap may be generated between the side edges of adjacent panel pairs at the center of the opening. The present applicant has proposed a form in which a gap removing tool for removing the gap is provided at the side end of the guide rail (Japanese Patent Application No. 8-28659).
[0004]
As shown in FIG. 8, the clearance remover has a rectangular frame-like housing 51 fitted into the side end of the guide rail 50, and an elastic arm 53 that pushes the runner 52 back is integrally provided in the housing 51. Yes. Since the elastic arm 53 pushes back the door panel 54 toward the center of the opening via the runner 52, it is possible to prevent a gap from being generated between the pair of panels.
[0005]
[Problems to be solved by the invention]
In this way, each panel pair captured by the runner catcher can identify the open part of each panel at the center of the opening, which is the normal position, and when necessary, release the engaged state with the runner catcher and open the end side like the sliding door. The side can be opened. However, since the runner catcher originally captured and caught the panel pair so as not to move, it is inevitable that a gap is generated between the side edges of adjacent panel pairs in the closed state where all the panels are deployed. Even if the gap remover is added, the door panel cannot be pushed back.
[0006]
It is not impossible to eliminate the gap when fully closed by using a gap remover. However, in this case, it is necessary to capture and engage the runner so that it can be moved by the runner catcher for the return stroke. However, each time the panel pair is opened and closed, the runner reciprocates and the panel pair rattles. Inevitable. The extra parts cost and construction work are required for the amount of gap removal tool added. In most cases, the runner catcher is attached to the guide rail using the dead space at the end of the rail, and therefore cannot be used together when the clearance remover is attached to the end of the rail.
[0007]
An object of the present invention is to obtain a runner catcher having a runner catching function and a gap removing function, so that the panel pair captured by the runner catcher can be easily opened and closed, and adjacent in a fully closed state. The purpose is to improve the appearance by avoiding a gap between the panel pair.
[0008]
[Means for Solving the Problems]
In the present invention, a runner catcher having a runner catching function and a gap removing function is obtained by adding a gap removing mechanism to the runner catcher as a base.
[0009]
That is, the runner catcher of the present invention is attached to the side end of the guide rail 1 and engages and captures the runner 5 provided at the upper side end of the panel pair P. The runner catcher includes a guide frame 24 that is fixed to the guide rail 1, a pressing block 25 that is supported by the guide frame 24 in a reciprocating manner along the running direction of the runner 5, and a pressing block 25 that is pushed out from the guide frame 24. And an energizing spring 26. A capturing tool 39 for engaging and capturing the connecting body 14 provided on the runner 5 is provided on the outer end of the pressing block 25. In a state where the connecting body 14 of the runner 5 is captured by the capturing tool 39, the panel pair P receives the spring force of the spring 26 and is urged to move toward the center of the opening.
[0010]
The pressing block 25 is supported by the guide frame 24 so as to be slidable back and forth, and is pushed and urged by a compression coil spring 26 provided between the two 24 and 25. A connecting body 14 protrudes from the side end of the body 12 of the runner 5, and a catching tool 39 that elastically engages the connecting body 14 is provided on a surface of the pressing block 25 facing the connecting body 14.
[0011]
The guide frame 24 is integrally provided with a guide portion 28 provided with a guide hole 7 having a quadrangular cross section and an inverted T-shaped fastening portion 29 protruding from the lower surface of the guide portion 28. The internal thread body 30 that is opposed to the fastening portion 29 in the vertical direction is disposed near the side end of the guide frame 24. The bolt 33 is screwed into the female screw body 30 from the lower surface side of the fastening portion 29, and the rail bottom wall 1 a of the guide rail 1 is vertically clamped by the female screw body 30 and the fastening portion 29, whereby the guide frame 24 is attached to the guide rail 1. Fix it.
[0012]
[Action]
The pressing block 25 is always advanced and biased by the spring 26. In this advanced state, the interval between the catches 39 positioned at both ends of the rail is such that the runners 5 positioned at both ends of the rail when the folding door is fully closed. It is set slightly smaller than the interval between the connecting bodies 14. Therefore, in a state where the coupling body 14 is engaged and captured by the capturing tool 39, when the adjacent panel pair P is fully extended to close the opening surface, the pressing block 25 resists the urging force of the spring 26 and guide frame 24. It is pushed in. At this time, the runner 5 receives the pressing force of the spring 26 via the catching tool 39 and the pressing block 25. As a result, the panel pair P is pushed toward the center of the opening, so that the adjacent panel pair P can be brought into close contact with the center of the opening.
[0013]
Since the catching tool 39 is provided in the pressing block 25 that is advanced and biased by the spring 26, when the runner 5 is engaged and caught by the catching tool 39, the opening side end side is also opened when the panel pair P is opened and closed. The door panel P1 can always be urged to move toward the center of the opening. Therefore, it is possible to prevent the door panel P1 from moving freely within the range of the push-back stroke as the panel pair P is opened and closed, and to prevent the panel pair P from rattling.
[0014]
Since the pressure block 25 is slidably supported by the guide frame 24 and the pressure block 25 is advanced and urged by a spring 26 provided between the two 24 and 25, the clearance can be removed. Runner catcher equipped with functions can be compactly combined as one unit part. According to the runner catcher in which the guide portion 28 and the fastening portion 29 are integrally provided above and below the guide frame 24, the number of components is reduced.

The socket 21 includes a suspension hole 21a provided along the axis and an engagement groove 21b formed in an L shape so as to penetrate the suspension hole 21a. The plug 20 is assembled in advance on the door panels P1 and P2. After inserting the suspension hole 21a, the horizontal shaft body 19 is rotated and the plug 20 is engaged and fixed.
[0019]
The runner shaft 11 also serves as a height adjusting screw shaft, and the lower half of the screw shaft is screwed into a screw hole provided in the case 18. The upper half shaft portion of the runner shaft 11 is inserted into the body 12 of the traveling portion 9 from the lower surface side, and is then connected to the body 12 so as to be relatively rotatable by caulking the shaft end. The height of the door panels P1 and P2 can be adjusted by rotating the hexagonal operation portion 22 provided in the middle of the shaft to change the screwing amount of the screw shaft into the case 18.
[0020]
In order to engage and capture the runner 5 at the side end of the guide rail 1, a pair of runner catchers is disposed at both ends of the guide rail 1. In FIG. 1, the runner catcher includes a guide frame 24 fitted and fixed to the guide rail 1, a press block 25 that is guided and supported so as to be slidable back and forth by the guide frame 24, and a compression that pushes and biases the press block 25 from the guide frame 24. The coil spring 26 is used.
[0021]
In FIG. 4, the guide frame 24 is integrally formed with a guide portion 28 having a square-shaped guide hole 27 whose right side surface is open and an inverted T-shaped fastening portion 29 projecting from the lower surface of the guide portion 28. The chamber 31 is formed on the left side surface of the guide frame 24 and accommodates the female screw body 30. Grooves 32 for receiving the rail bottom wall 1 a of the guide rail 1 are formed on the front and rear surfaces between the guide portion 28 and the fastening portion 29. An insertion hole 34 for the bolt 33 is formed between the lower surface near the left end of the fastening portion 29 and the chamber 31 as shown in FIG. An escape groove 35 is provided in a penetrating manner in the center of the upper wall of the guide portion 28 facing the guide hole 27.
[0022]
The pressing block 25 is formed of a rectangular parallelepiped plastic block. As shown in FIG. 6, a recess 36 is provided in the center of the left end to avoid contact interference with the female screw 30 and the bolt 33, and the spring 26 is received before and after the recess 36. A spring receiving hole 37 is formed. At the right end of the pressing block 25, a catching tool 39 for engaging and catching the connecting body 14 provided on the body 12 of the runner 5 is provided so as to project sideways. The catching tool 39 is formed by projecting a pair of elastically deformable front and rear catching arms 40 in a petal shape, and a contact claw 41 for receiving the body 12 projects from the front and back of each catching arm 40. It is.
[0023]
After assembling the pair of springs 26 in the spring receiving holes 37 of the pressing block 25, the pressing block 25 is inserted into the guide hole 27 from the spring 26 side, and a stopper screw ( When the screw 42 is screwed in, the pressing block 25 is pushed and urged by the spring 26 in a direction to advance from the guide frame 24, and is held at a standby position where the head of the screw 42 contacts the right end of the escape groove 35. .
[0024]
After the female screw body 30 made of a plate nut is loaded into the chamber 31 of the guide frame 24 in the above state, the guide portion 28 is inserted into the guide rail 1 from the outside, and at the same time, the rail bottom wall 1a is inserted into the groove 32. Engage. In this state, the bolt 33 is screwed into the female screw body 30 through the insertion hole 34, whereby the rail bottom wall 1a is vertically clamped by the female screw body 30 and the fastening portion 29, and the runner catcher can be fixed to the guide rail 1 ( (See FIG. 7).
[0025]
The runner 5 is attached so that the check parts 15 oppose each door panel P1 * P2 which comprises the panel pair P. FIG. As a result, in a state where the panel pair is refracted into a V shape, as shown in FIG. 5, the restraining portions 15 come into contact with each other to regulate the proximity distance between the pair of door panels P1 and P2, and further at the contact end. The teeth 16 engage with each other to constrain the movement of the runner 5 on the counterpart side. In this way, when the adjacent runners 5 and 5 are constrained to each other via the check portions 15 and 15, the pair of runners 5 and 5 move together, so that the runners 5 and 5 can be well prevented from meandering. Accordingly, the panel pair P moves straight forward even under a state in which a large tilting moment acts on the runners 5.
[0026]
When each of the left and right panel pairs P is extended to be flush with each other and the opening surface is closed, the connecting body 14 provided on the runner 5 located at both ends is captured by the capturing tool 39 protruding from the pressing block 25. . In this state, the left-right distance of the capturing tool 39 is set to be smaller than the left-right distance of the connector 14. Therefore, when each panel pair P is fully extended, the pressing block 25 is pushed into the guide hole 27 against the urging force of the spring 26 as shown in FIG. The spring 26 also serves as a buffer when the runner 5 suddenly contacts the catching tool 39.
[0027]
Unlike the case where the operating head of the screw 42 is received by the groove end of the escape groove 35 in the state where the pressing block 25 is slid to the rail side end side as described above, the tension of the spring 26 is passed through the runner 5. It acts on the door panel P1. As a result, as shown by the arrows in FIG. 6, each panel pair P is moved to the center of the opening surface by the force of the spring 26, and the side end surfaces of the adjacent door panels P2 and P2 are brought into close contact with each other. That is, in a state where the opening surface is closed by the left and right panel pairs P, it is possible to prevent a gap from being generated between the panel pairs P and improve the appearance of the folding door. In addition, since the clearance gap which arises in the side edge of an opening surface is covered with the plate-shaped door concealment, it does not become a problem.
[0028]
When the panel pair P is opened and closed, a force in a direction to advance from the guide frame 24 and a force in a direction to retreat into the guide frame 24 are applied to the pressing block 25. However, since the pressing block 25 is always urged to move in the direction of advancement by the spring 6, as the panel pair P is opened and closed, the pressing block 25 reciprocates within the range of the push-back stroke for removing the gap. It is possible to prevent rattling, and the panel pair P can be opened and closed smoothly.
[0029]
In addition to the above-described embodiment, the capturing tool 39 may be formed in a leaf shape in plan view, and the connecting body 14 having a bifurcated elastic arm may be provided on the body 12 side. Moreover, the connection body 14 and the capture | acquisition tool 39 should just be a pair of engagement body which mutually engages, and do not necessarily need to be a male-female engagement relationship. The spring 26 can be changed to a tension spring or a torsion coil spring. A commercially available hex nut can be used as the female screw body 30.
[0030]
【The invention's effect】
In the present invention, a catching tool 39 for engaging and catching the connecting body 14 of the runner 5 is provided in the pressing block 25, and the pressing block 25 is supported in a reciprocating manner by a slide frame 24 attached to the side end of the guide rail 1. Further, the spring 26 is moved and urged in a direction to advance from the guide frame 24 so that the panel pair P can be moved and urged toward the center of the opening in a state where the runner 5 is engaged and captured. Accordingly, the fully-closed panel pair P can be brought into close contact with each other at the center of the opening surface to prevent a gap from being formed between the side edges of the adjacent door panels P2 and P2. It is possible to easily open and close the panel pair P by eliminating floating between the push-back strokes.
[0031]
When a runner catcher is added to the runner catcher and the runner catcher with the runner catching function and the gap removal function is configured as one unit part, when using a dedicated gap remover separately from the runner catcher In comparison, it is advantageous in that the cost of parts and the labor of construction can be reduced, and the total cost of the folding door can be reduced accordingly.
