Description

[Technical field]

[0001] The present invention relates to a shower hook. [Background technology]

[0002] Conventionally, a shower hook is used to attach a shower head to a wall or the like. A typical shower hook is fixed to a supporting surface such as a wall. The orientation of the shower hook and the orientation of the shower head are greatly restricted by the supporting surface. In response to this, shower hooks have been developed in recent years that can grip and be fixed to a pipe-shaped fixed part used as a handrail or the like (see, for example, Patent Documents 1 and 2). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Utility Model Registration No. 3056094 [Patent Document 1] JP 2002-97686 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, the shower hooks in Patent Documents 1 and 2 are only designed to grip a pipe-shaped fixed part, making it difficult to fasten them to a flat fixed part such as a counter or a bath chair.

[0005] The present invention has been made in consideration of the above problems, and has an object to provide a shower hook that can be fixed to fixing parts of a wider variety of shapes. [Means for solving the problem]

[0006] In order to solve the above problems, the present invention proposes the following means. (1) A first aspect of the present invention is a shower hook comprising a first gripping member having a first flat surface formed thereon, and a second gripping member having a second flat surface formed opposite the first flat surface and capable of moving toward and away from the first gripping member, wherein when directions that run along the first flat surface and intersect each other are defined as a first direction and a second direction, a first recess that is recessed from the first flat surface is formed in an intermediate portion of the first flat surface in the first direction, over the entire length of the first flat surface in the second direction.

[0007] In this invention, for example, a pipe-shaped fixed part is placed in a first recess extending in the second direction in the first gripping member and brought into contact with the second flat surface of the second gripping member, and the first gripping member and the second gripping member are brought close to each other to grip the fixed part. Also, for example, a flat plate-shaped fixed part is brought into contact with the first flat surface of the first gripping member and the second flat surface of the second gripping member, and the first gripping member and the second gripping member are brought close to each other to grip the fixed part. As described above, the shower hook can be fixed to a wider variety of shapes of fixed parts, including not only pipe-shaped but also flat plate-shaped fixed parts.

[0008] (2) A second aspect of the present invention may be a shower hook as described in (1), in which a second recess is formed in the middle of the second flat surface in the first direction, the second recess being recessed from the second flat surface over the entire length of the second flat surface in the second direction. In this invention, for example, by arranging a pipe-shaped fixed portion in a second recess extending in the second direction in the second gripping member, the shower hook can be more stably fixed to the pipe-shaped fixed portion by the first recess and the second recess.

[0009] (3) A third aspect of the present invention may be a shower hook as described in (1) or (2), in which the second gripping member has a first through hole having a female thread formed on its inner surface, and a first shaft member having a male thread formed on its outer surface that mates with the female thread. In this invention, by rotating the first shaft member about the first axis of the first shaft member, the second gripping member can be moved along the first axis by engaging the female thread with the male thread.

[0010] (4) A fourth aspect of the present invention may be a shower hook as described in (3), in which the second gripping member has a second through hole formed therein, extends along the first shaft member, and has a second shaft member with a portion of itself positioned within the second through hole. In this invention, the second gripping member can be guided to move along the second shaft member by moving the second shaft member inside the second through hole.

[0011] (5) A fifth aspect of the present invention may be a shower hook as described in (3) or (4), comprising: a main body that supports the first shaft member rotatably about a first axis of the first shaft member; and a support member that detachably supports a shower head and is attached to a surface of the main body rotatably about an intersecting axis that intersects the surface. In this invention, the first shaft member can be supported by the main body so as to be rotatable about the first axis line. Then, by rotating the support member about the intersecting axis line, the orientation of, for example, a shower head supported by the support member about the intersecting axis line can be adjusted. Effect of the Invention

[0012] The shower hook of the present invention can be fixed to a fixing portion having a wider variety of shapes. [Brief description of the drawings]

[0014] Hereinafter, one embodiment of a shower hook according to the present invention will be described with reference to FIGS. As shown in Fig. 1, the shower hook 1 of this embodiment can be fixed to a pipe-shaped fixed part 101 by gripping the same. For example, the fixed part 101 is used as a handrail or the like on a bath chair 100 or the like. As shown in Figures 1 to 3, the shower hook 1 comprises a first gripping member 10, a second gripping member 15, a main body 20, a first shaft member 30, a second shaft member 35, a support member 40, and a connecting portion 45.

[0015] The first gripping member 10 has a first gripping piece 11A and a first support member 12. The first gripping piece 11A and the first support member 12 are each formed in a flat plate shape having a rectangular shape when viewed in the thickness direction. The first gripping piece 11A has a flat first flat surface 11aA facing a first side in the thickness direction of the first gripping piece 11A. Here, directions that run along the first flat surface 11aA and are perpendicular to each other are defined as a first direction X and a second direction Y. The first direction X and the second direction Y may be directions that intersect each other. A direction perpendicular to each of the first direction X and the second direction Y is defined as an orthogonal direction Z. The orthogonal direction Z may be a direction intersecting each of the first direction X and the second direction Y. The orthogonal direction Z is a direction along the thickness direction of each of the first gripping piece 11A and the first support member 12. One side of the first direction X is defined as a first side X1, and the opposite side to the first side X1 is defined as a second side X2.

[0016] In this example, when viewed in the orthogonal direction Z, the length of the first gripping piece 11A in the first direction X is longer than the length of the first gripping piece 11A in the second direction Y. The first support member 12 is similar to the first gripping piece 11A. When viewed in the orthogonal direction Z, the length of the first gripping piece 11A in the first direction X and the length of the first gripping piece 11A in the second direction Y may be equal to each other.

[0017] A first recess 11bA is formed in the middle of the first flat surface 11aA in the first direction X. The first recess 11bA is recessed from the first flat surface 11aA toward the inside of the first gripping piece 11A over the entire length of the first flat surface 11aA in the second direction Y. The first recess 11bA has an arc shape when viewed in the second direction Y. The first recess 11bA separates the first flat surface 11aA into a first surface 11cA disposed on a first side X1 from the first recess 11bA and a second surface 11dA disposed on a second side X2 from the first recess 11bA. In this example, the length of the first surface 11cA in the first direction X is longer than the length of the second surface 11dA in the first direction X.

[0018] The length of the first surface 11cA in the first direction X may be shorter than the length of the second surface 11dA in the first direction X, or the length of the first surface 11cA in the first direction X may be equal to the length of the second surface 11dA in the first direction X. The first support member 12 is fixed to the surface of the first gripping piece 11A opposite to the first flat surface 11aA.

[0019] The second gripping member 15 has a second gripping piece 11B and a second support member 16. Here, as shown in FIG. 1 and FIG. 2, a reference plane S1 is defined between the first gripping piece 11A and the second gripping piece 11B. In this embodiment, the configuration of the first gripping piece 11A and the configuration of the second gripping piece 11B are plane-symmetrical with respect to the reference plane S1. For this reason, the configuration of the first gripping piece 11A is indicated by adding the capital letter "A" to the number of the symbol, or the number and the lowercase English letter. The configuration of the second gripping piece 11B corresponding to the first gripping piece 11A is indicated by adding the capital letter "B" to the same number or the number and the lowercase English letter as the symbol of the first gripping piece 11A. This avoids redundant explanations. For example, the first flat surface 11aA of the first gripping piece 11A and the second flat surface 11aB of the second gripping piece 11B, which will be described later, are plane-symmetrical with respect to the reference plane S1.

[0020] 1 to 3, the second gripping piece 11B is formed with a flat second flat surface 11aB. The second flat surface 11aB faces the first flat surface 11aA. The term "facing" as used herein refers not only to facing each other without contacting each other, but also to contacting each other. A second recess 11bB is formed in the middle of the second flat surface 11aB in the first direction X. The second recess 11bB is recessed from the second flat surface 11aB toward the inside of the second gripping piece 11B over the entire length of the second flat surface 11aB in the second direction Y. The second gripping piece 11B and the first gripping piece 11A are formed of synthetic resin such as rubber.

[0021] The second support member 16 is formed in a flat plate shape having a rectangular shape when viewed in the perpendicular direction Z. The second support member 16 extends further toward the second side X2 than the first support member 12. As shown in FIG. 2, a first through hole 16a and a second through hole 16b are formed in a portion of the second support member 16 (second gripping member 15) that extends further toward the second side X2 than the first support member 12. The first through hole 16a and the second through hole 16b penetrate the second support member 16 in the perpendicular direction Z. The first through hole 16a has a gripping female screw (female screw) 16c formed on the inner peripheral surface thereof. The first through hole 16a is disposed on the second side X2 than the second through hole 16b. The second support member 16 is formed of, for example, a stainless steel plate material. The second support member 16 is fixed to the surface of the second gripping piece 11B opposite to the second flat surface 11aB.

[0022] The first gripping piece 11A and the second gripping piece 11B do not have to be symmetrical with respect to the reference plane S1.

[0023] The main body 20 is a cover for the shower hook 1. The shape of the main body 20 is not limited. In this example, the main body 20 is formed in a box shape with an opening on the side facing the first side X1. As shown in FIGS. 1 to 3, specifically, the main body 20 has a first side wall 21, second side walls 22 and 23, a top wall 24, and a bottom wall 25. The first side wall 21, the second side walls 22, 23, the top wall 24, and the bottom wall 25 are each formed in a flat plate shape that has a rectangular shape when viewed in the thickness direction.

[0024] The first side wall 21 is disposed such that the thickness direction of the first side wall 21 is along the first direction X. As shown in Fig. 2 and Fig. 4, when viewed in the first direction X, a side wall through hole 21a penetrating the first side wall 21 in the first direction X is formed in the center of the first side wall 21. Here, the surface of the first side wall 21 (main body 20) facing the second side X2 is referred to as a main body surface (surface) 21b. As shown in FIGS. 1 to 3, the second side wall 22 extends from an end of the first side wall 21 on a first side Y1 in the second direction Y (hereinafter simply referred to as the first side Y1) toward the first side X1. The second side wall 23 extends from an end of a second side Y2 (hereinafter simply referred to as the second side Y2) opposite to the first side Y1 in the second direction Y of the first side wall 21 toward the first side X1. The second side wall 23 is disposed to face the second side wall 22 in the second direction Y.

[0025] The top wall 24 extends from an end of the first side Z1 (hereinafter simply referred to as the first side Z1) of the first side wall 21 in the perpendicular direction Z toward the first side X1. As shown in Fig. 2, the top wall 24 has top wall through holes 24a and 24b. The top wall through hole 24a is disposed closer to the second side X2 than the top wall through hole 24b. It is preferable that a cylindrical bearing 27a is disposed in the top wall through holes 24a and 24b. As shown in FIGS. 1 to 3, the top wall 24 is continuous with the first support member 12. The bottom wall 25 extends from an end of a second side Z2 (hereinafter simply referred to as the second side Z2) opposite to the first side Z1 in the perpendicular direction Z of the first side wall 21 toward the first side X1. As shown in FIG. 2, bottom wall through holes 25a and 25b are formed in the bottom wall 25. The bottom wall through hole 25a is disposed closer to the second side X2 than the bottom wall through hole 25b. It is preferable that a cylindrical bearing 28a is disposed in the bottom wall through holes 25a and 25b. The bottom wall 25 is disposed to face the top wall 24 in the orthogonal direction Z.

[0026] The main body 20 and the first support member 12 are integrally formed, for example, by bending a stainless steel plate material.

[0027] 1 to 3, the first shaft member 30 and the second shaft member 35 are each formed in a shaft shape (rod shape). The first shaft member 30 and the second shaft member 35 each extend along the perpendicular direction Z. That is, the second shaft member 35 extends along the first shaft member 30. A male shaft thread 31 is formed on the outer circumferential surface of the first shaft member 30 at a middle portion in the orthogonal direction Z. As shown in FIG. 2, the male shaft thread 31 of the shaft member 30 is fitted into the gripping female thread 16c of the second gripping member 15. A portion of the first side Z1 of the shaft male thread 31 is disposed in a bearing 27a in a top wall through hole 24a of the top wall 24. An end of the second side Z2 of the first shaft member 30 is disposed in a bearing 28a in a bottom wall through hole 25a of the bottom wall 25. The first shaft member 30 is restricted from moving in the perpendicular direction Z relative to the top wall 24 and the bottom wall 25 by a restricting member 27b such as an E-type retaining ring. A handle 32 is fixed to an end of the first side Z1 of the first shaft member 30. Hereinafter, the axis of the first shaft member 30 will be referred to as a first axis O1. The first axis O1 extends along the orthogonal direction Z. The main body 20 supports the first shaft member 30 so as to be rotatable about a first axis O1.

[0028] An intermediate portion (a part) of the second shaft member 35 in the orthogonal direction Z is disposed within the second through-hole 16b of the second holding member 15. An end of the second shaft member 35 on the first side Z1 is disposed in a bearing 27a in the top wall through-hole 24b of the top wall 24. An end of the second shaft member 35 on the second side Z2 is disposed in a bearing 28a in the bottom wall through-hole 25b of the bottom wall 25. The second shaft member 35 is restricted from moving in the perpendicular direction Z relative to the top wall 24 and the bottom wall 25 by a restricting member 28b such as an E-shaped retaining ring.

[0029] As shown in FIGS. 1 to 3, the support member 40 has a support body 41 and two support pieces 42. For example, the support body 41 is formed in a rectangular parallelepiped shape. As shown in Fig. 4, a large diameter hole 41b is formed in a first surface 41a of the support body 41. For example, the large diameter hole 41b is formed in a cylindrical shape and extends in the first direction X. A small diameter hole 41c is formed in the bottom surface of the large diameter hole 41b. The small diameter hole 41c is formed in a cylindrical shape and extends in the first direction X. The inner diameter of the small diameter hole 41c is smaller than the inner diameter of the large diameter hole 41b. The small diameter hole 41c reaches a second surface 41d of the support portion main body 41 opposite to the first surface 41a.

[0030] 1 to 3, the two support pieces 42 are fixed to the first surface 41a of the support portion main body 41. The two support pieces 42 are disposed in the second direction Y with a gap between them. As shown in FIG. 1, a shower head (shower) 110 is detachably supported between two support pieces 42 of the support member 40. For example, the support member 40 is formed by injection molding or the like using a synthetic resin.

[0031] As shown in FIG. 4, the connecting portion 45 has a receiving member 46, an annular member 47, a screw member 48, and a coil spring 49. Here, the receiving member 46 and the coil spring 49 are formed in a cylindrical shape, the annular member 47 is formed in an annular shape, and the screw member 48 is formed in an axial shape. The central axes of the receiving member 46, the annular member 47, the screw member 48, the coil spring 49, and the side wall through-hole 21a of the first side wall 21 of the main body 20 are arranged coaxially with a common axis (axis line). Hereinafter, the common axis will be referred to as the intersecting axis line O3.

[0032] The receiving member 46 has a cylindrical body 52 and a locking portion 53 . The cylindrical body 52 is formed in a cylindrical shape. A connecting female screw 52a is formed on the inner circumferential surface of the cylindrical body 52. ​​The cylindrical body 52 is arranged along the first direction X. An end of the cylindrical body 52 on the first side X1 in the first direction X is arranged in the side wall through hole 21a of the first side wall 21 of the main body 20. The locking portion 53 is formed in a disk shape. The locking portion 53 is disposed coaxially with the cylindrical body 52 on an end surface of the first side X1 of the cylindrical body 52. ​​The locking portion 53 is locked to the first side wall 21 from the first side X1 of the first side wall 21.

[0033] The outer diameter of the annular member 47 is larger than the outer diameter of the cylindrical body 52 of the receiving member 46. The inner diameter of the annular member 47 is approximately the same as the inner diameter of the cylindrical body 52. ​​The annular member 47 is engaged with the cylindrical body 52 from the second side X2 of the cylindrical body 52. The screw member 48 has a shaft portion 55 and a head portion 56 . The shaft portion 55 is formed in a shaft shape. A connecting male screw 55a is formed on the outer circumferential surface of the shaft portion 55. The shaft portion 55 is disposed along the first direction X, and the connecting male screw 55a is fitted into the connecting female screw 52a of the receiving member 46. The head 56 is fixed to the end of the shaft portion 55 on the second side X2. The diameter of the head 56 is larger than the diameter of the shaft portion 55. The head 56 is engaged with the annular member 47 from the second side X2 of the annular member 47. The head 56 and the cylindrical body 52 of the receiving member 46 sandwich the annular member 47 in the first direction X.

[0034] The coil spring 49 is disposed radially outside the cylindrical body 52 of the receiving member 46. The coil spring 49 is engaged with the annular member 47 from a first side X1 of the annular member 47. The coil spring 49 is engaged with the small diameter hole 41c of the support portion main body 41 from a second side X2 of the small diameter hole 41c. The receiving member 46, the annular member 47, the screw member 48, and the coil spring 49 are each formed of, for example, stainless steel.

[0035] For example, the support member 40 is moved to the second side X2 relative to the main body 20 to separate the first side wall 21 of the main body 20 and the support portion main body 41 of the support member 40 in the first direction X, while compressing the coil spring 49 in the first direction X against the elastic force of the coil spring 49. The orientation of the support member 40 relative to the main body 20 around the intersecting axis O3 is appropriately adjusted, and the support member 40 is moved to the first side X1 relative to the main body 20, so that the first side wall 21 of the main body 20 and the support portion main body 41 of the support member 40 come into contact in the first direction X. As described above, the support member 40 is attached to the main body surface 21b of the main body 20 so as to be rotatable about the intersecting axis O3.

[0036] Shower hook 1 configured as above is fixed to pipe-shaped fixed portion 101 of chair 100. Specifically, a user grips the handle 32 and rotates the first shaft member 30 in a predetermined direction around the first axis O1. Then, the shaft male thread 31 of the first shaft member 30 engages with the grip female thread 16c of the second grip member 15, causing the second grip member 15 to move to the second side Z2 relative to the first grip member 10. At this time, since the intermediate portion of the second shaft member 35 in the orthogonal direction Z is disposed within the second through hole 16b of the second grip member 15, deviation in position or posture of the second grip member 15 around the first axis O1 is suppressed when the second grip member 15 moves.

[0037] When the first gripping member 10 and the second gripping member 15 are sufficiently separated in the perpendicular direction Z, as shown in FIG. 1, the fixed part 101 is disposed between the first gripping member 10 and the second gripping member 15. For example, the fixed part 101 is disposed in the second recess 11bB of the second gripping member 15, and the first shaft member 30 is rotated in a direction opposite to a predetermined direction about the first axis O1. Then, the second gripping member 15 moves to the first side Z1 relative to the first gripping member 10. The fixed part 101 is disposed in the first recess 11bA of the first gripping member 10, and the fixed part 101 is gripped by the gripping members 10 and 15. As described above, the second gripping member 15 can move toward and away from the first gripping member 10 in the orthogonal direction Z.

[0038] As described above, in the shower hook 1 of this embodiment, the pipe-shaped fixed part 101 is disposed in the first recess 11bA extending in the second direction Y in the first gripping member 10, and is disposed in the second recess 11bB extending in the second direction Y in the second gripping member 15. By bringing the first gripping member 10 and the second gripping member 15 closer to each other in the perpendicular direction Z, the shower hook 1 can be more stably fixed to the fixed part 101 by the first recess 11bA and the second recess 11bB. Also, as shown in FIG. 5, for example, a flat fixed portion 102 is brought into contact with a first flat surface 11aA of the first gripping member 10 and a second flat surface 11aB of the second gripping member 15, and the first gripping member 10 and the second gripping member 15 are brought closer to each other to grip the fixed portion 102. As described above, shower hook 1 can be fixed to fixed parts 101, 102 having a wider variety of shapes, including not only pipe-shaped fixed part 101 but also flat plate-shaped fixed part 102.

[0039] The second gripping member 15 is formed with a first through hole 16a having a gripping female thread 16c formed on its inner circumferential surface, and the shower hook 1 is equipped with a first shaft member 30. By rotating the first shaft member 30 around the first axis O1, the gripping female thread 16c and the shaft male thread 31 are fitted together, so that the second gripping member 15 can be moved along the first axis O1. A second through hole 16b is formed in the second gripping member 15, and the shower hook 1 includes a second shaft member 35. The second shaft member 35 moves within the second through hole 16b, thereby guiding the second gripping member 15 to move along the second shaft member 35.

[0040] The shower hook 1 comprises a main body 20 and a support member 40. The main body 20 supports the first shaft member 30 so that the first shaft member 30 can rotate about the first axis O1. By rotating the support member 40 about the intersecting axis O3, the orientation of the shower head 110 supported by the support member 40 about the intersecting axis O3 can be adjusted.

[0041] As shown in FIG. 6, the shower hook 1 of this embodiment can be gripped by contacting the wavy, flat fixed portion 104 with the first flat surface 11aA of the first gripping member 10 and the second flat surface 11aB of the second gripping member 15.

[0042] Although one embodiment of the present invention has been described in detail above with reference to the drawings, the specific configuration is not limited to this embodiment, and changes, combinations, deletions, etc. of the configuration are also included within the scope that does not deviate from the gist of the present invention. For example, in the above embodiment, the second recess 11bB may not be formed in the second gripping member 15. In this case, the pipe-shaped fixed portion 101 is brought into contact with the second flat surface 11aB of the second gripping member 15, and the first gripping member 10 and the second gripping member 15 are brought close to each other to grip the fixed portion 101. The shower hook 1 does not necessarily have to include the main body 20, the first shaft member 30, the second shaft member 35, the support member 40, and the connecting portion 45. In this case, the second gripping member 15 is not formed with the first through hole 16a and the second through hole 16b. [Explanation of symbols]
