Description

Technical Field

[0001] The present invention relates to an extraction jig for a housing for extracting a housing from a cup fixed to a door panel.

Background Art

[0002] Conventionally, a fitting runner for fittings that slides a hanging door or a folding door along a guide rail has been known. In a fitting runner, generally, a cup is fixed to a door panel, and a housing (holder member) is attached to the cup.

[0003] However, there are cases where it is necessary to remove the housing once attached and fixed to the cup. Specifically, when it is desired to paste wallpaper on the back surface after attachment or when the fitting runner fails, it is necessary to detach the housing from the cup.

[0004] For example, in the fitting runner of Patent Document 1, a holder member (corresponding to the housing) is fitted into the cup, and an engaging claw provided at the lower part of the housing is hooked on an engaging angular hole provided at the bottom surface of the cup, so that the two are fixed to each other. In this fitting runner, the attachment / detachment lever formed integrally with the housing is lifted upward with a finger to release the engagement.

Summary of the Invention

Problems to be Solved by the Invention

[0006] When removing conventional housings, including the technology described in Patent Document 1 mentioned above, it was necessary to push up the release lever while inserting a finger into the gap between the door and the rail and pulling it out. However, the gap between the door and the rail is narrow, making it difficult to insert a finger and pull it out.

[0007] Therefore, the present invention aims to provide a housing removal tool that facilitates the removal of the housing from the cup. [Means for solving the problem]

[0008] To achieve the above objective, the housing extraction jig of the present invention is applied to a housing mounting structure comprising: a cup embedded in a door panel and having a recess; and a housing connected to a runner via a connecting shaft and having a fitting arm that can be fitted into the recess and is fitted into the cup, the housing extraction jig comprises a hook portion that can be inserted between the door panel and the rail from the end face direction of the door panel and can be hooked onto the connecting shaft. [Effects of the Invention]

[0009] Thus, the housing extraction jig of the present invention is an extraction jig for a housing that is applied to a housing mounting structure comprising a cup and a housing, and is equipped with a hook portion that can be inserted between the door panel and the rail from the end face direction of the door panel and hooked onto the connecting shaft. Using a housing extraction jig with this configuration makes it easier to pull the housing out of the cup by inserting the hook portion between the door panel and the rail. [Brief explanation of the drawing]

[Figure 9] This is an enlarged view of section A in Figure 5. [Modes for carrying out the invention]

[0011] Embodiments of the present invention will be described below with reference to the drawings. However, the components described in the following embodiments are illustrative and are not intended to limit the technical scope of the present invention to them alone. [Examples]

[0012] (Overall configuration of the sliding door) First, the overall configuration of the sliding door H to which the housing extraction jig (4) of the present invention is applied will be explained using Figure 1. As shown in Figure 1, the sliding door H consists of a guide rail 8 fixed to a door frame (not shown) and a door panel 9 to which a runner 3 having wheels 31-34 that run within the guide rail 8 is attached. In other words, the runner 3 is attached to the housing 2 via a connecting shaft 5, and the housing 2 is attached to the door panel 9 via a cup 1, thereby attaching the runner 3 to the door panel 9.

[0013] The cup 1 has a cup-shaped main body with a U-shaped cross-section as a whole, which is fitted and fixed in an embedding groove with a U-shaped cross-section formed at the corner of the door panel 9. The upper part and the outer end of the cup 1 facing the edge of the door panel 9 are openings. Further, at the bottom of the cup 1, a recess 11 into which a fitting arm 21 of a housing 2 described later is fitted is formed at a position slightly closer to the outer end from the center. The cup 1 is fixed to the door panel 9 by wood screws (not shown) at the side wall and the bottom respectively.

[0014] And the housing 2 is fitted into the cup 1 so as to slide from the outer end side. The cup 1 and the housing 2 can be switched between a fixed posture (a state where sliding is impossible) and a released posture (a state where sliding is possible) according to the position of the fitting arm 21. That is, by fitting the fitting arm 21 into the recess 11 (in a natural state) or pushing it up with a finger, the housing 2 can be easily fixed to or released from the cup 1.

[0015] The housing 2 includes an outer frame portion forming an outer frame that is slidably inserted from the opening at the outer end of the cup 1, and an inner frame portion that holds adjustment screws for adjusting the front, rear, left, and right positions of the connecting shaft 5, and is integrally injection-molded from synthetic resin. That is, the outer frame portion is formed corresponding to the inner surface shape of the cup 1 and can slide through the outer end side of the cup 1.

[0016] And the housing 2 of this embodiment integrally has a fitting arm 21 that can be fitted into the recess 11 provided in the cup 1. As shown in the enlarged view of FIG. 2, the fitting arm 21 has a convex portion 21b (to be inserted into the recess 11) protruding downward at the tip side of a thin plate-shaped straight portion 21a, and is formed in a crank shape as a whole. The fitting arm 21 is relatively thin and formed so as to be elastically deformed. Note that the fitting arm 21 is not limited to being integrally formed with the housing 2. For example, the fitting arm 21 may be configured as a separate part and pivotally supported by the housing 2.

[0017] And the tip 21c of the fitting arm 21 is exposed from the end face of the door plate 9 to the outer end side (front side), and can be pushed up with a finger from the outer end side of the door plate 9. Therefore, by pushing up the tip 21c of the fitting arm 21 with a finger, the fitting arm 21 rotates (elastically deform to the right) with the side closer to the connecting shaft 5 as a fulcrum. That is, by this pushing-up operation, the fitting of the convex portion 21b on the lower side of the fitting arm 21 into the concave portion 11 is released, and the housing 2 can be removed. As will be described later, in this embodiment, the fitting arm 21 is pushed up by the extraction jig 4 of the housing.

[0018] (Configuration of the extraction jig) Next, the configuration of the extraction jig 4 of the housing will be described with reference to FIGS. 3 to 5. This extraction jig 4 of the housing is a jig used when removing the housing 2 from the cup 1 (door plate 9). The extraction jig 4 of the housing has both a function of hooking the connecting shaft 5 of the runner 3 and a function of releasing the fitting arm 21 of the housing 2. Here, the specific structure of the extraction jig 4 of the housing will be described.

[0019] The extraction jig 4 of the housing is formed of synthetic resin, and integrally includes a triangular main body 40 having a finger hole 44, a hook portion 41 continuously extending upward from the upper portion of the main body 40, a protruding portion 42 disposed and protruding at the lower front of the main body 40, and a positioning guide 43 disposed at the base of the hook portion 41.

[0020] The front side of the main body 40 is formed flat except for the protruding portion 42, so that when removing the housing 2, the adhesion between the extraction jig 4 and the housing 2 can be enhanced (the contact area is widened) and it can be stably held. A finger hole 44 for hanging a finger when pulling out is formed in the main body 40.

[0021] The hook portion 41 is bent horizontally into an L-shape and has a thickness that allows it to be inserted into the gap between the door panel 9 and the rail 8. For example, it is preferable that the hook portion 41 has a thickness of 5 mm or less.

[0022] Furthermore, the upper surface of the hook portion 41 in this embodiment has a tapered shape that slopes downward from the base to the tip. That is, as will be described later, when the fitting arm 21 is pushed up by the inclined surface 42a of the projection 42, the upper surface of the hook portion 41 is designed not to interfere with the guide rail 8. In addition, the width of the base end of the hook portion 41 is formed to fit into a recess (formed for finger grip) formed on the upper surface of the housing 2.

[0023] The projection 42 is positioned on the lower front of the main body 40 so that when the main body 40 is rotated downward with the hook portion 41 hooked onto the connecting shaft 5, it comes into contact with the tip 21c of the fitting arm 21. The projection 42 protrudes in a triangular shape when viewed from the side, and its inclined surface 42a pushes up the tip 21c of the fitting arm 21. Furthermore, the inclined surface 42a has a recess 42b formed at its uppermost position closest to the main body 40, into which the tip 21c of the fitting arm 21 engages (see also Figure 9).

[0024] The positioning guide 43 is designed to fit onto the end face of the housing 2 at the top of the main body 40 and near the base of the hook portion 41, with the width narrowing towards the tip. Therefore, when the extraction jig 4 is rotated with the hook portion 41 as the pivot point, the positioning guide 43 restricts its position in the left-right (door thickness direction) direction.

[0025] (How to use) Next, the method of using the housing extraction tool 4 will be explained using Figures 6 to 9. The method of using the housing extraction tool 4 includes at least the following three steps: 1) to 3).

[0026] 1) Insert the hook portion 41 from the end face direction of the door panel 9 between the door panel 9 and the rail 8 and hook it onto the connecting shaft 5 (Figure 6): In other words, the worker holds the housing removal jig 4 in their hand and rotates the L-shaped part of the hook portion 41 to the back of the connecting shaft 5, hooking it onto the connecting shaft 5. In this state, as shown in Figure 6, the fitting arm 21 of the housing 2 is fitted into the recess 11 of the cup 1, and the housing 2 is unable to slide relative to the cup 1. The fitting arm 21 is biased in the direction of fitting into the recess 11 by its own elastic force, so the fixed position is maintained unless the tip 21c of the fitting arm 21 is lifted.

[0027] 2) Rotating the housing removal tool 4 to push up the fitting arm 21 with the inclined surface 42a of the projection 42 (Figures 7 and 9): In other words, the worker, while keeping the hook portion 41 hooked onto the connecting shaft 5, rotates the main body portion 40 of the housing removal jig 4 by pushing it downwards with their hand. At this time, the hook portion 41 fits into the recess on the upper surface of the housing 2, and the position in the left-right direction (door thickness direction) is restricted by the positioning guide 43 on the front side of the main body portion 40, so that the projection portion 42 rotates to a position where it is directly facing the fitting arm 21.

[0028] Then, the projection 42 pushes up the tip 21c of the fitting arm 21. More specifically, the inclined surface 42a of the projection 42 pushes up the tip 21c of the fitting arm 21 against the elastic force of the fitting arm 21. Then, the tip 21c of the fitting arm 21 slides along the inclined surface 42a and fits into the recess 42b. In this state, as shown in Figures 7 and 9, the fitting arm 21 of the housing 2 is detached from the recess 11 of the cup 1, and the housing 2 can slide relative to the cup 1.

[0029] 3) The step of removing the housing 2 by pulling the housing removal tool 4, which is integrated with the housing 2, towards the front (Figure 8): In other words, since the connection between cup 1 and housing 2 is released, the worker can remove housing 2 (and runner 3) by manually sliding the housing removal jig 4, which is integrated with housing 2, towards the front.

[0030] In this way, by using the housing removal jig 4, two functions can be simultaneously achieved through an extremely simple action of hooking and rotating: the hook portion 41 to hook the connecting shaft 5 of the runner 3, and the projection portion 42 to release the fitting arm 21 of the housing 2.

[0031] (effect) Next, the effects of the housing extraction jig 4 in the embodiment will be listed and explained.

[0032] (1) As described above, the housing removal tool 4 of the embodiment is a housing removal tool 4 that is applied to a housing mounting structure comprising a cup 1 embedded in a door panel 9 and having a recess 11, and a housing 2 connected to a runner 3 via a connecting shaft 5 and having a fitting arm 21 that can be fitted into the recess 11 and is fitted into the cup 1. The housing removal tool 4 is further equipped with a hook portion 41 that can be inserted between the door panel 9 and the rail 8 from the end face direction of the door panel 9 and hooked onto the connecting shaft 5. Using a housing removal tool 4 with this configuration, the housing 2 can be easily pulled out of the cup 1 by inserting the hook portion 41 between the door panel 9 and the rail 8.

[0033] (2) Furthermore, by providing a projection 42 having an inclined surface 42a that approaches the fitting arm 21 from the end face direction of the door panel 9 and pushes up the fitting arm 21, the constraint of the housing 2 on the cup 1 is released by pushing up the fitting arm 21 and detaching it from the recess 11, allowing the housing 2 to slide. In other words, by using the housing removal jig 4, two functions can be simultaneously achieved by the extremely simple action of hooking and turning: the function of hooking the connecting shaft 5 of the runner 3 with the hook portion 41, and the function of releasing the fitting arm 21 of the housing 2 with the projection portion 42.

[0034] (3) Furthermore, the hook portion 41 is formed to fit into a recess formed on the upper surface of the housing 2 when the fitting arm 21 is pushed up by the inclined surface 42a, thereby preventing the housing removal jig 4 from shifting position from side to side. In addition, the removal jig 4 can be rotated (counterclockwise in Figure 6) even in the narrow gap between the door panel 9 and the rail 8.

[0035] (4) Furthermore, the upper surface of the hook portion 41 is tapered from the base to the tip so that the upper surface of the hook portion 41 does not interfere with the rail 8 when the fitting arm 21 is pushed up by the inclined surface 42a. As a result, when the housing extraction jig 4 is rotated, the upper surface near the tip of the hook portion 41 can rotate without interfering with the rail 8.

[0036] (5) Furthermore, since a recess 42b is formed at the upper end of the inclined surface 42a of the projection 42, into which the tip 21c of the fitting arm 21 engages, a click sensation is obtained, making it easier to know when fitting is complete, and the housing removal tool 4 and the housing 2 become one unit, making it easier to remove.

[0037] (6) Furthermore, the method of using the housing removal tool 4 in this embodiment consists of the steps of: inserting the hook portion 41 between the door panel 9 and the rail 8 from the end face direction of the door panel 9 and hooking it onto the connecting shaft 5; rotating the housing removal tool 4 to push up the fitting arm 21 with the inclined surface 42a of the projection portion 42; and pulling the housing removal tool 4, which is integrated with the housing 2, towards the front to remove the housing 2. With this configuration of the housing removal tool 4, the two functions of hooking onto the connecting shaft 5 of the runner 3 by the hook portion 41 and releasing the fitting arm 21 of the housing 2 by the projection portion 42 can be achieved simultaneously by the extremely simple action of hooking and rotating, making it easier to remove the housing 2.

[0038] Although embodiments of the present invention have been described in detail above with reference to the drawings, the specific configuration is not limited to these embodiments, and any design modifications that do not depart from the spirit of the present invention are included in the present invention.
