Description

[Technical Field]

[0001] The present invention relates to a two-member sliding structure and a hanger. [Background technology]

[0002] Conventionally, there have been known hanging devices as shown in patent documents.

[0003] Patent Document 1 discloses a device equipped with a vertically movable rod suitable for placement near a window, but the shape of the vertically movable rod is fixed and does not change, so it remains in that state even when not in use, making it unavoidable that it is bulky.

[0004] Patent Document 2 discloses a wall-mounted stand that can be switched between a use state in which the surface of the plate is approximately horizontal and a storage state in which the back surface of the plate is positioned along the wall surface by adjusting the length of the wire from the suspender using multiple positioning and fixing parts, and the upright surface part forms a shelf when the plate is in the storage state. However, changing the configuration between the use state and the storage state requires operating an adjustment member of the positioning and fixing parts. Operating the adjustment member changes the position at which the wire is held in the adjustment member through-hole, adjusting the length of the wire from the suspender and positioning the plate relative to the wire, thereby changing the state.

[0005] [Patent Document 1] Registered Utility Model No. 3164539 [Patent Document 2] Japanese Patent Application Publication No. 2023-110717 Summary of the Invention [Problem to be solved by the invention]

[0006] An object of the present invention is to provide a two-member sliding structure that can easily realize shape changes of two members such as vertically movable rods. Another object of the present invention is to provide a clothes hanger equipped with a two-member sliding structure that can easily change the shape of two members, such as a vertically movable rod. [Means for solving the problem]

[0007] The present invention provides a two-member sliding structure including a base-end fixed part, first and second slide members slidably arranged relative to one another, and a flexible connecting member connecting the first slide member and the base-end fixed part. The second slide member includes an abutment portion that abuts against the connecting member. The connecting member has a length adjustment portion that changes the extension length between the base-end fixed part and the first slide member, and changing this extension length causes the first slide member and the second slide member to slide.

[0008] In carrying out the present invention, the first slide member and the second slide member may be configured to slide and rotate in accordance with the change in the extension length.

[0009] Furthermore, the first slide member may be provided with a holding portion that slidably supports the second slide member and allows the second slide member to protrude from one end thereof, and the connecting member may enter the holding portion from one end thereof, be folded back at the folding back portion of the second slide member, and have its tip end fixed to the first slide member, so that the second slide member may slide in and out of one end of the holding portion as the extension length changes.

[0010] Furthermore, the second slide member may comprise an arm base end that moves linearly along the longitudinal direction of the holding portion, and an arm tip end that is rotatably connected to the tip of the arm base end via a hinge, and the holding portion may comprise a direction change portion that abuts against the arm tip end that attempts to protrude along the longitudinal direction of the holding portion, and the arm tip end may be configured to be guided by the direction change portion and protrude while changing direction in a direction intersecting the longitudinal direction of the holding portion.

[0011] The present invention also provides a hanger in which the sliding structure of the two members is applied to both ends. The first sliding member is the main bar of the hanger, and the second sliding member is an arm that extends from both ends of the main bar. When the connecting member is extended from the length adjustment part and the main bar is pulled down, the arms protrude from both ends of the main bar and rotate perpendicular to the main bar, causing the tips of the arms to abut against a wall surface, thereby maintaining a distance between the main bar and the wall surface.

[0012] In addition, the arm can be configured to be constantly biased by an actuating member so as to be stored within the holding portion of the main bar, and the movement of the arm can be restricted by abutting the tip of the arm against a wall surface. [Effects of the Invention]

[0013] The present invention provides a two-member sliding structure that can easily realize shape changes of two members such as vertically movable rods. The present invention also provides a clothes hanger with a two-member sliding structure that allows the shape of the two members to be easily changed. [Brief explanation of the drawings]

[0015] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. [Two-component sliding structure]

[0016] The sliding structure of the first sliding member and the second sliding member in this embodiment has the structure shown in Fig. 1, and this structure is used in the hanger shown in Fig. 2. In the hanger 10, the first sliding member is embodied as the main bar 11, and the second sliding member is embodied as the arm 21, so the terms main bar 11 and arm 21 will be used in the explanation of the sliding structure.

[0017] In this sliding structure, the main bar 11 and the arm 21 are arranged to be able to slide relative to each other. A base end fixing portion 31 is provided on a wall W of a building or the like, and the base end of a flexible connecting member 32, such as a wire, is fixed to the base end fixing portion 31. The tip of the connecting member 32 is fixed to the tip fixing portion 14 of the main bar 11. The arm 21 is provided with a folded portion 22 on its base end side as an abutment portion that abuts against the base end fixing portion 31. In this embodiment, a pulley is used as the folded portion 22 to reduce friction caused by abutment with the connecting member 32, but this may be changed to another structure as long as it abuts with a low coefficient of friction.

[0018] The connecting member 32 has a length adjustment section that changes the extension length L between the base end fixing section 31 and the main bar 11. In this embodiment, the length adjustment section is made up of multiple components that are dispersedly arranged, so the length adjustment section will be explained after explaining these components. The length adjustment section changes the extension length L, so that the main bar 11 and the arm 21 slide. [Handling of the holding part and connecting parts]

[0019] The main bar 11 has a holding part 12 that slidably supports the arm 21 and allows the arm 21 to protrude from one end. In this example, the main bar 11 is made of a hollow pipe with one open end, so this hollow internal space becomes the holding part 12, and the arm 21 slides in and out from the open end.

[0020] The connecting member 32 is routed as follows: The connecting member 32 enters the holding part 12 from one end thereof, folds back at the folding back part 22, and has its tip end fixed to the main bar 11 at the tip fixing part 14. This routing structure allows the arm 21 to slide in and out of the one end of the holding part 12 as the extension length L changes.

[0021] When connecting member 32 enters holding portion 12 from one end thereof, it is guided by bending portion 13 and routed so as to bend at approximately 90 degrees. In this example, a pulley is used as bending portion 13 so that connecting member 32 can be smoothly guided, but this may be changed to another structure as long as it abuts with a low coefficient of friction. [Operating member]

[0022] The arm 21 is constantly biased by an actuating member 15 so as to be housed within the holding portion 12 of the main bar 11. In this example, a tension coil spring stretched between the inner end 16 of the holding portion 12 and the base end of the arm 21 is used as the actuating member 15, but other types of springs may be used, or a mechanical or electrical structure other than a spring, such as a gear, may be used to pull the arm 21 into the main bar 11. [Length adjustment section]

[0023] The aforementioned length adjustment section is composed of a structure for pulling the arm 21 into the main bar 11 and components related to the handling of the connecting member 32, and specifically is composed of a holding section 12, a bending section 13, a folded section 22, a tip fixing section 14 and an operating member 15. By this length adjustment portion, the main bar 11 and the arm 21 operate as follows. [Shortest feeding length L]

[0024] Due to the biasing force of the actuating member 15, in a free state, the arm 21 is always retracted into the main bar 11, and the extension length L of the connecting member 32 is at its shortest (FIGS. 1(A) and 2(A)). In this state, the section distance between the bent portion 13 and the folded-back portion 22 and the section distance between the bent portion 13 and the folded-back portion 22 are at their longest, and the connecting member 32 spans both sections. Therefore, most of the connecting member 32 is housed within the holding portion 12 of the main bar 11, and the extension length L of the connecting member 32 is at its shortest. [Longest state of feeding length L]

[0025] From this state, when a person pulls down the main bar 11, most of the arm 21 protrudes from inside the main bar 11, and the extension length L of the connecting member 32 reaches its longest state (FIGS. 1(B) and 2(B)).

[0026] In this state, the section distance between the bent portion 13 and the folded portion 22 and the section distance between the bent portion 13 and the folded portion 22 are at their shortest, and the connecting member 32 spans both sections. Therefore, the majority of the connecting member 32 (the length equivalent to the sum of the section distance between the bent portion 13 and the folded portion 22 in the shortest state and the section distance between the bent portion 13 and the folded portion 22) is unwound outside the holding portion 12 of the main bar 11, and the unwound length L of the connecting member 32 is at its longest.

[0027] The operating member 15 may be powered by a motor or the like, so that the arm 21 can be advanced without manual intervention. The length adjustment unit may be equipped with a take-up reel, and this take-up reel may be located on the base end fixing unit 31 side so that the length of the connecting member 32 can be adjusted at a location other than the main bar 11. [Direction change section 17] Next, the direction changing section 17 will be described mainly with reference to FIGS. The present invention can be implemented as having the basic structure shown in FIG. 1, but can also be implemented as a structure that additionally includes a direction changer 17. FIG. 2 shows a clothes hanger 10 having arms 21 at both ends that extend at approximately right angles to the main bar 11, which is achieved by adding a direction changer 17 shown in FIGS. [Arm 21 structure]

[0028] The arm 21 in this example has an arm base end 24 and an arm tip end 23 . The arm base end portion 24 moves linearly along the longitudinal direction of the holding portion 12. The base end of the arm tip portion 23 is rotatably connected to the tip of the arm base end portion 24 via a hinge 25. A pair of abutment protrusions 26 are formed near the base end of the arm tip portion 23 and protrude in the left and right directions. [Structure of the direction change section 17 of the main bar 11]

[0029] The holding portion 12 of the main bar 11 has direction change portions 17 on both sides that come into contact with the abutment protrusions 26 of the arm tip portion 23 that project along the longitudinal direction. The direction change portions 17 are groove-shaped and defined by an outward guide surface 18 in the shape of an arc with a relatively large radius and a return guide surface 19 in the shape of an arc with a relatively small radius. The holding portion 12 of the main bar 11 has an opening 20 at its tip, which opens over a range of approximately 90 degrees to accommodate the direction change of the arm tip portion 23. [Arm 21 movement]

[0030] With the above structure, the arm 21 moves forward and backward as follows. Outward path: As the payout length L increases, the arm 21 protrudes from the opening 20 of the main bar 11. At that time, the abutment protrusion 26 on the arm tip 23 is guided by the outward path guide surface 18 of the direction changer 17, and protrudes while changing direction to a direction intersecting the longitudinal direction of the holding part 12 of the main bar 11 (FIGS. 3(A) to 3(B)). In this example, the direction is changed to approximately a right angle as shown in FIGS. 2 and 4, but the angle can be changed as appropriate.

[0031] Return path: As the extension length L becomes shorter, the arm 21 enters the holding portion 12 of the main bar 11. At this time, the arm 21, which is constantly being pulled back by the operating member 15, has the abutment protrusion 26 on the arm tip 23 guided by the return path guide surface 19 of the direction change portion 17, and changes direction as it enters in a direction that intersects with the longitudinal direction of the holding portion 12 of the main bar 11 (Figure 4).

[0032] In this example, the distance between the outgoing path guide surface 18 and the returning path guide surface 19 is set larger than the contact protrusion 26, so the contact protrusion 26 moves along the outgoing path guide surface 18 on the outgoing path and along the returning path guide surface 19 on the returning path, but if the distance between the outgoing path guide surface 18 and the returning path guide surface 19 is set to be approximately the same as the size of the contact protrusion 26, the contact protrusion 26 will move while contacting both the outgoing path guide surface 18 and the returning path guide surface 19. Note that, as shown in Figures 3(B) and 4, it is also preferable to provide a guide 27 for guiding the connecting member 32 (not shown in Figures 3(B) and 4) just before the turning portion 22 or the like to suppress unnecessary interference between the connecting member 32 and the arm 21, but this is not a limitation. [Use of Hanger 10]

[0033] The hanger 10 is installed by attaching the tip fixing part 14 to a high place on the wall W. In this state, the extension length L is at its shortest due to the operating member 15, and the bar can be used without providing a special support for the main bar 11. However, if the tip fixing portion 14 is provided with a support as shown in FIG. 5, the bar will remain stable even in this state, even when a relatively heavy item such as a coat is hung on it.

[0034] When the main bar 11 is removed from the support and pulled down from this state, the extension length L shifts to the maximum state, and the arm 21 protrudes and extends from the main bar 11, and in the process, the arm tip 23 gradually changes direction toward the wall surface W.

[0035] When the extension length L reaches its maximum, the wall surface W and the arm tip 23 are approximately perpendicular to each other, and by abutting the tip against the wall surface W, the main bar 11 can be moved away from the wall surface W by the length of the arm tip 23, as shown in FIG. 2. The arm 21 is constantly biased in the retracting direction by the operating member 15, but the abutment of the tip of the arm tip 23 against the wall surface W and the shape of the return guide surface 19 make it possible to resist the force in the retracting direction. Therefore, the arm 21 is not retracted inadvertently and can be maintained in a stable state. Alternatively, a support 33 as shown in FIG. 6 may be fixed to the wall surface W, and the arm tip 23 may be supported by this support 33.

[0036] The present invention can be implemented in various ways, and the first slide member and the second slide member are implemented as the main bar 11 and the arm 21, but they are not limited to being rod-shaped, and can be changed to be plate-shaped, frame-shaped, etc. [Explanation of symbols]
