[0003] [Patent Document 1] Japanese Patent Application Publication No. 7-189306 Summary of the Invention [Problem to be solved by the invention]

[0004] An S-hook is formed by connecting two hooks facing in opposite directions to each other, forming an S-shape as a whole. In such an S-hook, when the upper hook is hooked onto an object, the tip of the lower hook is positioned in the same horizontal direction as the base end of the upper hook is positioned relative to the object. Therefore, when hanging or removing an object from the lower hook, the base end of the upper hook is likely to interfere with the object, leaving room for improvement in the stability of the attachment state to the object.

[0005] An object of the present disclosure is to provide a hanging hook and a hook unit that can improve the stability of the attachment state to an attachment target. [Means for solving the problem]

[0006] The hanging hook of the present disclosure comprises an upper hook-shaped portion for attachment to an attachment object and a lower hook-shaped portion for hanging an object, and when the upper hook-shaped portion is in an attached state attached to the attachment object, the horizontal orientation in which the tip is located relative to the downward opening of the upper hook-shaped portion and the horizontal orientation in which the tip is located relative to the upward opening of the lower hook-shaped portion are aligned.

[0009] Hereinafter, an embodiment of the present disclosure will be described. The same components are given the same reference numerals, and duplicated explanations will be omitted. In each drawing, for the convenience of explanation, components are omitted, enlarged, or reduced as appropriate. The drawings should be viewed according to the orientation of the reference numerals.

[0010] Please refer to FIG. 1. The hook unit 1 includes a hanging hook 10 and a towel rack 100 to which the hanging hook 10 is attached. The towel rack 100 is usually fixed to a wall 3. For example, the towel rack 100 is installed in a bathroom and fixed to a wall 3 that forms a bathroom space inside. The hanging hook 10 is attached to the towel rack 100 for use. In this specification, the horizontal front-back direction when the wall 3 to which the towel rack 100 is fixed is viewed from the front is defined as the X-axis direction, the horizontal left-right direction perpendicular to the X-axis direction is defined as the Y-axis direction, and the vertical direction perpendicular to the X-axis and Y-axis directions is defined as the Z-axis direction. The positive directions of the X-axis, Y-axis, and Z-axis are the directions of the arrows in FIG. 1, and the negative directions are opposite to the arrows. Specifically, the positive direction of the X-axis is the direction in which the towel rack 100 is located relative to the wall 3. The positive direction of the Y-axis is the left direction when the wall 3 to which the towel rack 100 is fixed is viewed from the front. The positive direction of the Z axis is upward in FIG.

[0011] The towel rack 100 includes a main body member 110 and a fixing member 130 that fixes the main body member 110 to the wall 3. The main body member 110 includes a back plate portion 112 and a hanging portion 120. The back plate portion 112 is a portion that is fixed to the wall 3 via the fixing member 130. The back plate portion 112 has a flat shape that extends in the Y-axis direction and the Z-axis direction with the X-axis direction being its plate thickness direction. As shown in FIG. 1, a decorative plate 116 may be attached to a part of the surface 114 of the back plate portion 112 that faces the positive direction of the X-axis. In this embodiment, the decorative plate 116 is attached to an area of ​​the back plate portion 112 where the hanging portion 120 is not located in the Z-axis direction, that is, to the upper part of the surface 114 of the back plate portion 112.

[0012] The hanging part 120 is a part for attaching the hanging hook 10 and a part for hanging an article. When the towel rack 100 is installed in a bathroom, the article to be hung on the hanging part 120 is a towel such as a body towel or face towel, a cleaning tool, etc. The hanging part 120 has a plate-like part that has a certain width in the vertical direction and extends in a straight line in the horizontal direction. In detail, the hanging part 120 includes two overhanging parts 122, 124 that extend in the X-axis positive direction from both ends of the back plate part 112 in the Y-axis direction, and a suspension part 126 that extends in the Y-axis direction and connects to the respective ends of the two overhanging parts 122, 124 in the X-axis positive direction. Each of the two overhanging parts 122, 124 has a flat plate shape that extends in the Z-axis direction with the Y-axis direction being the plate thickness direction of itself. Of the two overhanging parts 122, 124, the overhanging part 122 is located on the positive side of the Y axis, and the overhanging part 124 is located on the negative side of the Y axis. The suspension part 126 has a flat plate shape extending in the Z axis direction as well, with its plate thickness direction being in the X axis direction. The length of the suspension part 126 extending in the Y axis direction is longer than the length of each of the two overhanging parts 122, 124 extending in the X axis direction. The length of the suspension part 126 extending in the Y axis direction is longer than the length of the suspension part 126 extending in the Z axis direction. The two overhanging parts 122, 124 and the suspension part 126 are smoothly connected. In detail, in a certain region including a connecting portion where the two overhanging parts 122, 124 and the suspension part 126 are connected, the length in the Z axis direction and the plate thickness do not change substantially, and the connecting portion has a rounded corner shape in the XY plane view.

[0013] The back plate portion 112 and the hanging portion 120 define a communication hole 128 that communicates in the Z-axis direction. When an article is hung on the hanging portion 120, a part of the article is inserted into the communication hole 128 from above so as to straddle the upper end of the hanging portion 120, and another part of the article passes from above through the outside of the hanging portion 120, and is hung downward. The main body member 110 is made of a synthetic resin such as ABS resin. The back plate portion 112 and the hanging portion 120 included in the main body member 110 may be integrally molded as part of the same member.

[0014] The fixing member 130 may be a magnet that is attached to the surface of the back plate portion 112 of the main body member 110 facing the negative direction of the X-axis by adhesion or the like. The magnet in this embodiment may be a sheet-shaped rubber magnet. The magnet is attracted to the wall 3 by magnetic force, thereby removably fixing the main body member 110 to the wall 3. When the fixing member 130 is a magnet, the wall 3 is made of a material that can attract the magnet by magnetic force. This material may be a soft magnetic material such as iron, or a hard magnetic material such as a ferrite magnet. When the fixing member 130 is a magnet, the towel rack 100 can be fixed at any inclination in the YX plane. In this embodiment, it is described that the towel rack 100 is fixed to the wall 3 in the above-mentioned orientation as a normal usage mode.

[0015] The hanging hook 10 can be attached to the hanging part 120 of the towel rack 100. In detail, the hanging hook 10 can be attached to at least one of the suspension part 126 of the hanging part 120 and the two protruding parts 122, 124. An example in which the hanging hook 10 is attached to the suspension part 126 of the hanging part 120 will be described below.

[0016] Please refer to Figures 2 and 3. In Figure 3, in addition to a cross section of the hanging hook 10, a cross section of the hanging part 126 of the hanging part 120 when the hanging hook 10 is attached to the hanging part 126, and a cross section of a part of the article 5 hung from the hanging hook 10 are shown by hatching. Figure 3 is a cross section along the XZ plane perpendicular to the Y-axis direction which is the extension direction of the hanging part 126, and the depth of the paper is the Y-axis positive direction.

[0017] The hanging hook 10 includes an upper hook-shaped portion 20 and a lower hook-shaped portion 50. The upper hook-shaped portion 20 is bent between a base end 22 and a tip end 24, and has a hook-shaped shape as a whole. The upper hook-shaped portion 20 defines an opening that opens downward (hereinafter, simply referred to as a "downward opening 26"). The upper hook-shaped portion 20 is used for hanging and attaching to a hanging portion 120 of a towel rack 100 as an attachment target. The lower hook-shaped portion 50 is bent between a base end 52 and a tip end 54, and has a hook-shaped shape as a whole. The lower hook-shaped portion 50 defines an opening that opens upward (hereinafter, simply referred to as an "upward opening 56"). The lower hook-shaped portion 50 is used for hanging an article 5. The upper hook-shaped portion 20 and the lower hook-shaped portion 50 are connected to each other at their respective base ends.

[0018] When the hanging hook 10 is in an attached state (hereinafter simply referred to as "attached state") in which the upper hook portion 20 is attached to the hanging portion 120 of the towel rack 100 as the attachment target, the entire lower hook portion 50 and a part of the base end 22 side of the upper hook portion 20 are inserted into the communication hole 128 of the towel rack 100, and the tip 24 of the upper hook portion 20 is hooked on the hanging portion 120 so as to be located on the opposite side to the side facing the communication hole 128 of the hanging portion 120, i.e., in the positive direction of the X-axis. At this time, in a cross-sectional view along the XZ plane shown in FIG. 3, a part of the suspension portion 126 as the attachment target is accommodated in a space partitioned by the upper hook portion 20 (hereinafter simply referred to as "attachment target arrangement space 38"). The attachment target arrangement space 38 is a space partitioned by the upper hook portion 20 above the horizontal line passing through the tip 24 in FIG. 3. In such an attached state, the lower hook-shaped part 50 is located below the suspension part 126 to which it is attached, and the upward opening 56 is open in the positive direction of the X-axis.

[0019] When the hanging hook 10 is attached to a towel rack 100 installed in a bathroom, the item 5 hung from the lower hook portion 50 is a body brush, a face washing net, etc. These items 5 may be provided with a loop-shaped string material, and the item 5 may be hung by hooking the string material on the lower hook portion 50. In this case, the cross section of a part of the item 5 shown in FIG. 3 is a cross section of the string material hooked on the lower hook portion 50.

[0020] As shown in FIG. 3, in the attached state, the horizontal direction in which the tip 24 is located relative to the downward opening 26 of the upper hook-shaped part 20 and the horizontal direction in which the tip 54 is located relative to the upward opening 56 of the lower hook-shaped part 50 are aligned. As a result, in the horizontal direction in which the tip 54 is located relative to the upward opening 56 of the lower hook-shaped part 50, the base end 22 of the upper hook-shaped part 20 is not located, but the downward opening 26 is located, so that even when the article 5 is hung on or removed from the lower hook-shaped part 50, the article 5 is unlikely to interfere with the upper hook-shaped part 20. Therefore, the stability of the attachment state of the hanging hook 10 to the attachment target can be improved. Below, unless otherwise specified, the case in which the hanging hook 10 is in the attached state will be described.

[0021] In this embodiment, the horizontal orientation in which the tip 24 is located relative to the downward opening 26 of the upper hook portion 20 and the horizontal orientation in which the tip 54 is located relative to the upward opening 56 of the lower hook portion 50 are the same positive direction on the X-axis. In other words, the suspension hook 10 as a whole has a shape resembling the Arabic numeral "3". In this embodiment, in the attached state, the horizontal orientation in which the tip 24 is located relative to the base end 22 of the upper hook portion 20 and the horizontal orientation in which the tip 54 is located relative to the base end 52 of the lower hook portion 50 are the same positive direction on the X-axis.

[0022] The upper hook portion 20 contacts the hanging portion 120 from above at the first location 28. At the same time, the upper hook portion 20 can contact the hanging portion 120 from the negative X-axis direction at the second location 30, which is lower than the first location 28. In this embodiment, the upper hook portion 20 includes an upper end portion 32, a front hanging portion 34, and a back portion 36. The upper end portion 32 extends horizontally above the hanging portion 120. The front hanging portion 34 is located in the positive X-axis direction with respect to the hanging portion 120, and extends downward to the tip 24 on the tip 24 side from the upper end portion 32. The back portion 36 is located in the negative X-axis direction with respect to the hanging portion 120, and extends downward to the base end 22 on the base end 22 side from the upper end portion 32. In this case, the first location 28 is located at the upper end portion 32, and the second location 30 is located at the back portion 36. At least one of the first location 28 and the second location 30 may have a certain area range. In this case, the first location 28 may also be located in the front flap portion.

[0023] In this way, the upper hook portion 20 contacts the hanging portion 120 from above at the first location 28, and can contact the hanging portion 120 as the attachment object from the negative direction of the X-axis at the second location 30 that is lower than the first location 28. Therefore, the upper hook portion 20 contacts the attachment object from two or more different directions, which can further improve the stability of the attachment state of the hanging hook 10 to the attachment object.

[0024] The upper hook portion 20 may be slidable along the Y-axis direction relative to the hanging portion 120 when in the attached state. That is, the upper hook portion 20 may be attached to the hanging portion 120 by contact at the first point 28 and contact at the second point 30, but may not be fixed. In this case, even in the attached state, the upper hook portion 20 may have a gap that allows it to rotate slightly relative to the hanging portion 120 in the XZ plane. At this time, the upper hook portion 20 and the hanging portion 120 may be separated from each other at the second point. In other words, the contact between the upper hook portion 20 and the hanging portion 120 at the second point 30 may be achieved by the weight of the hanging hook 10 and the load of the article 5 hung from the lower hook portion 50. In this way, if the upper hook portion 20 and the hanging portion 120 are configured not to be fixed when in the attached state, the burden on the hanging hook 10 and the hanging portion 120 can be reduced.

[0025] The length in the Z-axis direction and the length in the X-axis direction of the portion of the hanging part 120 that is located in the attachment target arrangement space 38 correspond to the length in the Z-axis direction and the length in the X-axis direction of the attachment target arrangement space 38, respectively. Specifically, the length in the Z-axis direction of the portion of the hanging part 120 that is located in the attachment target arrangement space 38 is slightly smaller than the length in the Z-axis direction of the attachment target arrangement space 38, and the length in the X-axis direction is slightly smaller than the length in the X-axis direction of the attachment target arrangement space 38.

[0026] The upper hook portion 20 may further include a protruding portion 40. The protruding portion 40 is located directly below the hanging portion 120, and protrudes in the positive direction of the X-axis on the base end 22 side from the second location 30. In this manner, by including the protruding portion 40 in the upper hook portion 20, even if a user accidentally touches the hanging hook 10 and an external force is applied upward to the entire hanging hook 10, the protruding portion 40 can be caught on the lower end of the attachment target, thereby preventing the hanging hook 10 from coming off the attachment target.

[0027] As shown in FIG. 3, at least a part of the item placement space 58 in the lower hook part 50 is located in the X-axis negative direction from the attachment target placement space 38 in the upper hook part 20. The item placement space 58 is a space partitioned by the lower hook part 50 below the horizontal line passing through the tip 54 in FIG. 3. This allows the item 5 to be suspended at a position in the X-axis negative direction from the attachment target placement space 38 where a part of the attachment target is placed. Therefore, due to the load of the item 5, a rotational force is applied to the hanging hook 10 in the direction in which the lower hook part 50 faces the X-axis positive direction, that is, in the clockwise direction in the XZ plane in FIG. 3, with the first point 28 where the upper hook part 20 contacts the attachment target as a fulcrum. Then, since the upper hook part 20 is pressed against the attachment target at the second point 30, the stability of the attachment state of the hanging hook 10 to the attachment target can be further improved. In FIG. 3, the direction of the rotational force is shown typically by an arrow.

[0028] In this embodiment, the lower hook portion 50 includes an inclined portion 60 extending in a direction between the negative X-axis direction and the negative Z-axis direction, and a lower end portion 62 extending in the positive X-axis direction on the tip end 54 side of the inclined portion 60. The base end 52 side of the lower end portion 62 extends further in the negative X-axis direction than the surface of the back portion 36 of the upper hook portion 20 facing in the positive X-axis direction. The article 5 can be suspended at a position where the inclined portion 60 and the lower end portion 62 contact each other.

[0029] When the article 5 is suspended at a position in the negative X-axis direction relative to the attachment target arrangement space 38 in which the attachment target is arranged, the upper hook portion 20 may be configured to be pressed against the attachment target at the second location 30, making it difficult for the upper hook portion 20 to slide in the Y-axis direction relative to the attachment target. This allows, for example, the position of the hanging hook 10 relative to the attachment target to be determined without hanging the article 5, and the article 5 to be hung at the determined position, thereby stabilizing the position of the hanging hook 10 relative to the attachment target.

[0030] 3, the bottom surface 64 of the lower hook portion 50 facing the item arranging space 58 is inclined downward toward the base end 52 of the lower hook portion 50. As a result, the item 5 is guided in the negative X-axis direction within the item arranging space 58, so that the item 5 is more likely to be suspended at a position further in the negative X-axis direction than the attachment object arranging space 38 in which the attachment object is arranged. The effect of suspending the item 5 at a position further in the negative X-axis direction than the attachment object arranging space 38 in which the attachment object is arranged is as described above.

[0031] As shown in FIG. 3, the entire lower hook 50 is located in the negative X-axis direction from the surface 42 of the front hanging part 34 of the upper hook 20, which faces in the positive X-axis direction. One of the directions in which the surface 42 extends is along the Y-axis, and in FIG. 3, a plane including the surface 42 is indicated by a dashed line. With this configuration, the tip 54 of the lower hook 50 does not protrude in the positive X-axis direction from the upper hook 20, improving safety. The tip 54 of the lower hook 50 does not need to protrude in the positive X-axis direction from the surface 42, and may be aligned with the surface 42 in the X-axis direction. In this case, as in the example shown in FIG. 3, the lower hook 50 is not located in the positive X-axis direction from the surface 42 of the front hanging part 34, which faces in the positive X-axis direction.

[0032] The upper hook part 20 includes a curved part 44 that is convex in the negative direction of the X-axis between the first point 28 and the second point 30. The curved part 44 is separated from the hanging part 120 as the attachment target, and does not have a contact part with the hanging part 120. In this embodiment, the curved part 44 is located between the upper end part 32 and the back part 36. The curved part 44 is curved more gently than between the upper end part 32 and the front hanging part 34. In this way, the upper hook part 20 includes the curved part 44, so that the stress due to the load of the article 5 can be dispersed. In addition, when a load is applied to the upper hook part 20 when attaching or detaching the upper hook part 20 to the attachment target, the stress of the load can be dispersed.

[0033] The lower hook portion 50 includes a curved portion 66 that is convex in the negative X-axis direction at the lower end facing the negative X-axis direction. In this embodiment, the curved portion 66 is located between the inclined portion 60 and the lower end 62. The curved portion 66 is curved more gently than the portion between the upper end 32 and the front hanging portion 34. In this manner, by including at least one of the curved portion 44 and the curved portion 66, the hanging hook 10 can be made less likely to get caught on an item hung on the hanging portion 120 of the towel rack 100 even if it comes into contact with the hanging hook 10.

[0034] The upper hook part 20 is more flexible than the hanging part 120. The upper hook part 20 is made of a synthetic resin such as polypropylene. When the upper hook part 20 is made of polypropylene and the hanging part 120 is made of the above-mentioned ABS resin, the upper hook part 20 is more flexible than the hanging part 120. The upper hook part 20 and the lower hook part 50 may be integrally molded as part of the same member. In this way, by making the upper hook part 20 more flexible than the attachment target, the upper hook part 20 can be deformed when attaching and detaching the upper hook part 20 to and from the attachment target, and therefore attachment and detachment can be facilitated while reducing the burden on the attachment target.

[0035] An example of a method for attaching the hanging hook 10 to an attachment target will be described with reference to Figures 4 and 5. Figure 4 is a cross-sectional view showing a state in the middle of attaching the hanging hook 10 to the hanging part 120. Figure 5 is a cross-sectional view showing a state after the hanging hook 10 has been attached to the hanging part 120. Figures 4 and 5 are cross-sectional views at the same position as Figure 3.

[0036] As shown in FIG. 4, when attaching the hanging hook 10 to the hanging part 120, the hanging hook 10 is moved downward from above the hanging part 120 so that the hanging part 120 fits into the downward opening 26 of the upper hook part 20. At this time, the tip 24 side of the front hanging part 34 may be slightly deformed so that it opens in the positive direction of the X-axis. Since the tip 24 side of the front hanging part 34 is inclined in the part facing the hanging part 120 so that the downward opening 26 widens, the hanging part 120 can easily fit into the downward opening 26 of the upper hook part 20. As shown in FIG. 5, the protruding part 40 of the hanging hook 10 moves downward beyond the lower end of the hanging part 120, so that the hanging part 120 is accommodated in the attachment target arrangement space 38.

[0037] Next, variations of each of the components described above will be described.

[0038] The attachment target to which the hanging hook 10 is attached is not limited to a shape having an extension direction in the Z direction, such as the hanging part 120. The attachment target may be arranged at least at positions corresponding to the first point 28 and the second point 30 of the hanging hook 10, and the positional relationship between them may be fixed. For example, instead of the hanging part 126 of the towel rack 100, a towel rack having an upper hanging part connected at the upper side of each end of the two protruding parts 122, 124 in the positive direction of the X axis and a lower hanging part connected at the lower side may be used as the attachment target. The upper hanging part and the lower hanging part are arranged so that the upper hanging part corresponds to the first point 28 and the lower hanging part corresponds to the second point 30, respectively, and extend in the Y axis direction.

[0039] The hanging hook 10 may be attachable to a connecting portion between one of the two overhanging portions 122, 124 of the hanging portion 120 shown in Fig. 1 and the suspension portion 126. In that case, the shape of the hanging hook 10 may be a curved shape corresponding to the connecting portion between one of the two overhanging portions 122, 124 and the suspension portion 126 in the XY plane view, or the width along the extension direction of the hanging portion 120 may be reduced to make it less susceptible to the shape of the connecting portion.

[0040] The above embodiments and variations are examples. The technical ideas abstracted from these should not be interpreted as being limited to the contents of the embodiments and variations. Many design changes are possible in the contents of the embodiments and variations, such as changes, additions, and deletions of components. In the above-mentioned embodiments, the contents in which such design changes are possible are emphasized by adding the notation "embodiment". However, design changes are naturally permitted even in contents without such notation. The hatching on the cross section of the drawings does not limit the material of the object to which the hatching is added. Any of the components and expressions of the present disclosure that are mutually substituted between methods, devices, systems, etc. are also valid as aspects of the present disclosure.
