Embodiments for Carrying out the Invention

[0014] Hereinafter, embodiments of the hanger bar of the present invention will be described with reference to the drawings. The hanger bar is installed, for example, in a hotel or a residence and can suspend and hold a commercially available hanger. [First Embodiment]

[0015] The hanger bar 11 of the first embodiment will be described with reference to Figures 1 to 5. As shown in Figures 1 and 2, the hanger bar 11 comprises a plurality of rod-shaped bar bodies 12, a plurality of cap members 14 that can be attached to and detached from grooves 13 of the plurality of bar bodies 12, one or more joint members 15 that connect the bar bodies 12 to each other, a plurality of fasteners 18 for fixing the bar bodies 12 to the interior wall surface 16 or ceiling 17, and a plurality of fixing members 21 for fixing the joint members 15 to the bar bodies 12. Each of the fixing members 21 is made of a so-called screw. Each of the fixing members 21 may be made of a screw with a spring washer. When the fixing members 21 are made of screws with spring washers in this way, it is possible to prevent the screws from loosening even after long-term use. One cap member 14 is attached to one bar body 12. In this embodiment, one end of the fastener 18 is fixed to, for example, the interior wall surface 16, and the other end of the fastener 18 is fixed to, for example, the ceiling 17.

[0016] The joint member 15 is formed in an "L" shape from a metallic material, such as a zinc alloy. The joint member 15 may also be formed from other metallic materials, such as steel or an aluminum alloy. A painted surface is formed on the surface of the joint member 15. The joint member 15 has an "L" shaped elbow portion 22, a first end portion 23 protruding from one end of the elbow portion 22, and a second end portion 24 protruding from the other end of the elbow portion 22. Each of the first end portion 23 and the second end portion 24 protrudes away from the corner portion 22A of the elbow portion 22. Each of the first end portion 23 and the second end portion 24 is formed in a prismatic shape and can be inserted into the inner cavity portion 12B of the bar body 12 which is formed complementary to it. Each of the first end portion 23 and the second end portion 24 has a screw hole 25 for fastening the fixing member 21. The fixing member 21 is fastened to the screw hole 25 so as to pass through a through hole (not shown) provided in the connecting wall 26 of the bar body 12, which will be described later, thereby fixing the bar body 12 and the joint member 15.

[0017] The bar body 12 is formed from a metal material, such as an aluminum alloy. The bar body 12 may also be formed from other metal materials, such as steel or a zinc alloy. The bar body 12 is integrally formed, for example, by extrusion or other machining. The bar body 12 has a so-called square pipe shape with a square cross-section. A painted surface is formed on the surface of the bar body 12.

[0018] As shown in Figures 3 and 4, the bar body 12 has a top surface 31 located on the upper side, a pair of side surfaces 32 adjacent to the top surface 31, a bottom surface 33 adjacent to the side surfaces 32, a groove 13 provided on the top surface 31, and connecting walls 26 connecting the side surfaces 32. The groove 13 is provided in the middle of the width direction W perpendicular to the longitudinal direction L of the bar body 12, and penetrates the top surface 31. The groove 13 extends in the longitudinal direction L of the bar body 12.

[0019] The cap member 14 is configured to be detachably attached to the groove 13. The cap member 14 is integrally molded from, for example, a synthetic resin material. That is, the cap member 14 has an engaging portion 34 that can directly engage with the groove 13, and a flat cap portion 35 that extends from the engaging portion 34.

[0020] The engaging portion 34 has a pair of hook pieces 36. Each of the pair of hook pieces 36 has a support portion 36A and a claw portion 36B provided at the tip of the support portion 36A and protruding outward. The hook pieces 36 are flexible, and the support portion 36A can be bent to insert the claw portion 36B into the groove portion 13, or the support portion 36A can be bent to remove the claw portion 36B from inside the groove portion 13.

[0021] As shown in Figure 4, the cap portion 35 can cover the entire top surface 31. More specifically, as shown in Figure 4, the cap portion 35 is formed with a width slightly smaller (approximately 0.1 mm to several mm smaller) than the width of the top surface 31 in the width direction W, taking into account dimensional tolerances, etc. Therefore, even if the cap portion 35 is molded to be slightly larger due to variations, the cap portion 35 will not protrude beyond the top surface 31 in the width direction W. The cap portion 35 has a pair of arc-shaped shoulder portions 35A at both ends in the width direction W on its upper surface 35B.

[0022] Referring to Figure 5, the operation of the hanger bar 11 in this embodiment will be explained. The user can hang the hanger 41 by hooking the hook portion 41A of the hanger 41 onto the hanger bar 11. At that time, the hook portion 41A comes into contact with the pair of shoulder portions 35A of the cap portion 35. In this way, the hanger bar 11 comes into contact with the hanger 41 at two points (shoulder portions 35A), so the posture of the hanger 41 is stabilized. In addition, the hook portion 41A does not come into contact with the hanger bar 11 at any other point.

[0023] Figure 6 shows a first modified example of the hanger bar 11 of the first embodiment. In this modified example, both fasteners 18 of the hanger bar 11 are fixed to the ceiling. The hanger bar 11 as a whole has a "U" shape.

[0024] Figure 7 shows a second modified example of the hanger bar 11 of the second embodiment. In this modified example, both fasteners 18 of the hanger bar 11 are fixed to the interior wall surface 16. The hanger bar 11 as a whole has a "U" shape.

[0025] As shown in the first and second modified examples, the overall shape of the hanger bar 11 is arbitrary. The hanger bar 11 can take any shape by appropriately combining the bar body 12 and the joint member 15.

[0026] According to this embodiment, the following can be said: The hanger bar 11 comprises a bar body 12 having a rod shape with a rectangular cross-section and a groove 13 on a part of its top surface 31, and a cap member 14 having an engaging portion 34 that can engage with the groove 13, and a cap portion 35 that extends from the engaging portion 34, is flat, and onto which the hanger 41 can be hooked, and the cap portion 35 is capable of covering the entire top surface 31 of the bar body 12 when the engaging portion 34 is engaged with the groove 13.

[0027] With this configuration, the cap portion 35 can cover the entire top surface 31 of the bar body 12, thus preventing the hanger 41 from scratching the top surface 31 of the bar body 12 when repeatedly attaching and detaching the hanger 41 from the cap portion 35. This makes it possible to create a hanger bar 11 that can maintain a beautiful appearance for a long period of time.

[0028] In this case, the cap portion 35 has a pair of shoulder portions 35A at both ends in the width direction W on its upper surface, and the hook portion 41A of the hanger 41 contacts the cap portion 35 at the pair of shoulder portions 35A.

[0029] With this configuration, the hanger 41's hook portion 41A is in contact with a pair of shoulder portions 35A (contact at two or more points), so the hanger 41 remains stable on the hanger bar 11 without continuously vibrating around the bar body 12. This minimizes damage to the hanger bar 11 when attaching or detaching the hanger 41.

[0030] In the following embodiments, we will mainly describe the parts that differ from the first embodiment described above, and we will omit the description of parts that are common to the first embodiment. [Second Embodiment]

[0031] The hanger bar 11 of the second embodiment will be described with reference to Figures 8 to 10.

[0032] The cap member 14 is configured to be detachably attached to the groove 13. The cap member 14 is integrally molded from, for example, a synthetic resin material. That is, the cap member 14 has an engaging portion 34 that can directly engage with the groove 13, and a cap portion 35 that extends from the engaging portion 34 and is flat in shape. The cap portion 35 has an upper surface 35B. As shown in Figures 9 and 10, the upper surface 35B is arched so as to be convex in the direction away from the center 12A of the bar body 12. That is, in this embodiment, the thickness of the cap portion 35 is formed to be greater than that of the cap portion 35 of the first embodiment in the intermediate portion in the width direction W.

[0033] The cap portion 35 can cover the entire top surface 31. More specifically, as shown in Figure 10, the cap portion 35 is formed with a width slightly smaller than the width of the top surface 31 in the width direction W, taking into account its dimensional tolerances. Therefore, even if the cap portion 35 is molded to be slightly larger due to variations, the cap portion 35 will not protrude beyond the top surface 31 in the width direction W.

[0034] Referring to Figure 10, the operation of the hanger bar 11 in this embodiment will be explained. The user can hang the hanger 41 by hooking the hook portion 41A of the hanger 41 onto the hanger bar 11. At that time, the hook portion 41A can come into contact with the upper surface 35B of the cap portion 35. The hook portion 41A does not come into contact with the hanger bar 11 at any other point.

[0035] According to this embodiment, the following can be said: The cap portion 35 has an upper surface 35B, and the upper surface 35B is arched so as to be convex in the direction away from the center of the bar body 12.

[0036] This configuration allows the shape of the upper surface 35B of the cap portion 35 to fit the curve of the hook portion 41A of the hanger 41. This increases the contact area between the hook portion 41A of the hanger 41 and the cap portion 35, thereby increasing the frictional force acting between them. This prevents the hooked hanger 41 from continuously oscillating like a pendulum around the bar body 12, allowing the hanger bar 11 to stably suspend and hold the hanger 41. This prevents the risk of the hanger 41 damaging the bar body 12. Furthermore, the arched cap portion 35 allows the height of the cap portion 35 to be increased. This allows the hook portion 41A of the hanger 41 to be positioned at a predetermined gap from the bar body 12, reducing the risk of the hook portion 41A contacting the bar body 12 and preventing the hanger 41 from damaging the bar body 12. [Third Embodiment]

[0037] The hanger bar 11 of the third embodiment will be described with reference to Figures 11 to 13.

[0038] The cap member 14 is configured to be detachably attached to the groove 13. The cap member 14 is integrally molded from, for example, a synthetic resin material. That is, the cap member 14 has an engaging portion 34 that can directly engage with the groove 13, and a flat cap portion 35 that extends from the engaging portion 34. As shown in Figures 11 and 12, the cap portion 35 has a projection 42 in the middle of the width direction W that protrudes in a direction away from the center of the bar body 12. The projection 42 has a tip portion 42A on its upper surface. The tip portion 42A is arched so as to be convex in a direction away from the center 12A of the bar body 12.

[0039] The cap portion 35 can cover the entire top surface 31. More specifically, as shown in Figure 13, the cap portion 35 is formed with a width slightly smaller than the width of the top surface 31 in the width direction W, taking into account its dimensional tolerances. Therefore, even if the cap portion 35 is molded to be slightly larger due to variations, the cap portion 35 will not protrude beyond the top surface 31 in the width direction W.

[0040] Referring to Figure 13, the operation of the hanger bar 11 in this embodiment will be explained. A user can hang a hanger 41 by hooking the hook portion 41A of the hanger 41 onto the hanger bar 11. At this time, the hook portion 41A can come into contact with the tip portion 42A of the projection 42. The hook portion 41A does not come into contact with the hanger bar 11 at any other point. At this time, the projection 42 allows for a large gap between the hook portion 41A of the hanger 41 and the bar body 12, thus reducing the risk of the bar body 12 being damaged by the hook portion 41A. In addition, because the contact area between the hook portion 41A of the hanger 41 and the cap member 14 is reduced, the frictional force acting between the hanger 41 and the hanger bar 11 is reduced when the user moves the hanger 41 on the hanger bar 11, allowing the hanger 41 to be moved with less force.

[0041] According to this embodiment, the following can be said: The cap portion 35 has a projection 42 that protrudes in a direction away from the center 12A of the bar body 12.

[0042] This configuration reduces the contact area between the cap portion 35 and the hook portion 41A of the hanger 41, thereby reducing the frictional force acting between them. This allows the hanger 41 to be moved with less force, for example, when moving the hanger 41 that is hooked onto the hanger bar 11 toward one end in the longitudinal direction L of the hanger bar 11. This makes it possible to create a hanger bar 11 that is less prone to damage over a long period of time and is user-friendly. In addition, the protrusion 42 allows the hook portion 41A of the hanger 41 to be positioned at a predetermined gap from the bar body 12, thereby reducing the risk of the hook portion 41A coming into contact with the bar body 12 and preventing the risk of the hanger 41 damaging the bar body 12.

[0043] The tip 42A of the projection 42 is arched so as to be convex in the direction away from the center 12A of the bar body 12.

[0044] This configuration further reduces the contact area between the cap portion 35 and the hook portion 41A of the hanger 41, thereby reducing the frictional force acting between them. This allows, for example, when moving a hanger 41 that is hooked onto the hanger bar 11 toward one end in the longitudinal direction L of the hanger bar 11, the hanger 41 can be moved with less force. This makes the hanger bar 11 user-friendly. [Fourth Embodiment]

[0045] The hanger bar 11 of the fourth embodiment will be described with reference to Figures 14 to 16.

[0046] The cap member 14 is configured to be detachably attached to the groove 13. The cap member 14 is integrally molded from, for example, a synthetic resin material. That is, the cap member 14 has an engaging portion 34 that can directly engage with the groove 13, and a cap portion 35 that extends from the engaging portion 34 and is flat in shape. As shown in Figures 14 and 15, the cap portion 35 is curved in a wave-like manner with respect to the longitudinal direction L of the bar body 12. That is, the cap portion 35 has a plurality of peaks 43 and a plurality of valleys 44 alternating with respect to the longitudinal direction L. Each of the plurality of peaks 43 is smoothly continuous with the adjacent valleys 44 on both sides with respect to the longitudinal direction L.

[0047] The cap portion 35 can cover the entire top surface 31. More specifically, as shown in Figure 16, the cap portion 35 is formed with a width slightly smaller than the width of the top surface 31 in the width direction W, taking into account its dimensional tolerances. Therefore, even if the cap portion 35 is molded to be slightly larger due to variations, the cap portion 35 will not protrude beyond the top surface 31 in the width direction W.

[0048] The operation of the hanger bar 11 in this embodiment will be explained with reference to Figures 14 and 16. A user can hang a hanger 41 by hooking the hook portion 41A of the hanger 41 onto the hanger bar 11. At this time, the hanger 41 can be hooked onto the valley portion 44 of the cap portion 35. At this time, the position of the hanger 41 is stabilized because the position of the hanger 41 is determined by the valley portion 44 with respect to the longitudinal direction L of the bar body 12. At this time, the valley portion 44 of the cap portion 35 can come into contact with the hook portion 41A of the hanger 41 at both ends in the width direction W. In addition, multiple hangers 41 can be hooked onto the hanger bar 11 in an orderly manner with a uniform pitch. Furthermore, in this embodiment, because the peak portion 43 and the valley portion 44 are smoothly connected, a user can move the hanger 41 on the hanger bar 11 with relatively little force.

[0049] According to this embodiment, the following can be said: The cap portion 35 is curved in a wave-like manner with respect to the longitudinal direction L of the bar body 12.

[0050] This configuration allows the hangers 41 attached to it to be arranged at a constant pitch. Furthermore, since the wave-shaped design does not obstruct the movement of the hangers 41 on the hanger bar 11, the hangers 41 attached to the hanger bar 11 can be moved smoothly when moving them toward one end of the hanger bar 11 in the longitudinal direction L. [Fifth Embodiment]

[0051] The hanger bar 11 of the fifth embodiment will be described with reference to Figures 17 to 19.

[0052] The cap member 14 is configured to be detachably attached to the groove 13. The cap member 14 is integrally molded from, for example, a synthetic resin material. As shown in Figures 17 and 18, the cap member 14 has an engaging portion 34 that can directly engage with the groove 13, a flat cap portion 35 extending from the engaging portion 34, and a pair of protective pieces 45 extending downward from both ends of the cap portion 35 in the width direction W. As shown in Figure 18, in this embodiment, the cap portion 35 and the pair of protective pieces 45 are formed in an inverted "U" shape. The cap portion 35 can cover the entire top surface 31. Each of the pair of protective pieces 45 covers at least a portion of the side surface 32 of the bar body 12. In this embodiment, the protective piece 45 covers, for example, the upper half 32A of the side surface 32. The protective piece 45 may cover the entire side surface 32.

[0053] Referring to Figure 19, the operation of the hanger bar 11 in this embodiment will be explained. Users can hang hangers 41 by hooking the hook portion 41A of the hanger 41 onto the hanger bar 11. In this embodiment, because the cap member 14 covers the upper half 32A of the side surface 32 of the bar body 12, when a user hooks a hanger 41 onto the hanger bar 11 or removes a hanger 41 from the hanger bar 11, the hook portion 41A of the hanger 41 comes into contact with the bar body 12 and scratches the bar body 12 are prevented as much as possible.

[0054] According to this embodiment, the following can be said: The cap member 14 has a pair of protective pieces 45 extending downward from both ends in the width direction of the cap portion 35, and each of the pair of protective pieces 45 covers at least a portion of the side surface 32 of the bar body 12.

[0055] With this configuration, the side surface 32 of the bar body 12, which is the next most susceptible to scratches after the top surface 31 of the bar body 12, can be protected by the protective piece 45. This makes it possible to create a hanger bar 11 that is resistant to scratches for a long period of time.

[0056] The embodiments described above can be implemented with various further substitutions and modifications. Naturally, it is also possible to combine the above-described different embodiments and modifications as appropriate to constitute a single invention. [Explanation of Symbols]
