Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a support for detachably holding a shower head, and more particularly to a shower head support which can be securely fixed to a bar fixed to a wall or the like by a simple operation. Regarding the ingredients.

[0002]

2. Description of the Related Art A guide pipe is provided in a vertical direction on a wall of a bathroom or a wall of a dedicated shower booth, and the height of a support for a shower head can be adjusted with respect to the guide pipe. There is one described in Japanese Patent Publication No. 4-34218.

FIG. 11 is a transverse cross-sectional view of a main part showing a connecting structure of the shower head support described in this publication to a guide pipe.

A main body 53 of a support is attached so that two guide pipes 51 and 52 arranged in parallel with each other in the longitudinal direction penetrate therethrough, and a hanger 53a for detachably holding a shower head is attached to the front surface of the main body 53. In addition to that, a handle 54 for height adjustment is provided on the right side. A block 55 that constantly presses the pipe 51 with a spring 55a is incorporated on the surface opposite to the handle 54, and a stopper body 56 that sandwiches the pipe 51 together with the block 55 is provided on the handle 54 side. The stopper body 56 is connected to the end surface of the spindle 54a of the handle 54 by a spherical cam, so that
The stopper 56 is provided with a mechanism capable of being restrained and released at a rotation angle pitch of 4 degrees.

[0005]

In the connection between the spindle 54a and the stopper body 56 by the cam, the pressing force against the guide pipe 51 causes the stopper body 56 by the cam.
It depends on the amount of movement. Therefore, if the relationship between the shape of the cam and the movement of the stopper body 56 is not proper, for example, when the handle 54 is rotated toward the pressing side of the guide pipe 51 by the stopper body 56, the operation of the handle 54 is heavy. May be.

On the other hand, such a large operating force can be avoided by reducing the pushing amount of the stopper body 56 toward the guide pipe 51. However, if the pushing amount is reduced, the holding force between the block 55 and the stopper body 56 with respect to the guide pipe 51 becomes insufficient,
The fixing of the main body 53 becomes unstable, which causes slipping and the like.

As described above, if the displacement due to the cam connection between the spindle 54a and the stopper body 56 is absorbed by the spring 55a on the block 55 side, the handle 5
4 has an unfavorable influence on the operation force of No. 4 and the stable holding of the main body 53. Then, as one means for solving such obstacles, it is conceivable to set the dimensional accuracy and the assembly accuracy of each member to a high level. Cause

Further, the block 55 is provided to prevent the main body 53 from accidentally falling, and the block 55 and the spring 55a are provided on the opposite side of the stopper body 56 with the guide pipe 51 sandwiched in the radial direction. So the body 5
The bulk of 3 also increases accordingly. Therefore, the main body 53
There is a limit to the weight reduction of the main body 53, and it affects the operability when adjusting the height of the main body 53.

As described above, in the conventional shower head supporter, even if the processing accuracy and the assembly accuracy of each member are increased, it is inevitable that the operating force of the handle becomes heavy and the usability is reduced. Leaving a problem with.

An object to be solved in the present invention is to provide a shower head support which can always adjust the height of the support with a light operating force and can be made small and lightweight.

DISCLOSURE OF THE INVENTION The present invention is a supporter which is movably arranged following a guide member and has a shower head detachable, and a liner to be externally inserted to the guide member and the liner. The handle is rotatably connected to the handle, and the mover is installed in the connecting portion between the handle and the liner and is movable in the circumferential direction of the guide member. The handle and the mover are connected by a cam mechanism for converting the mover into and out of the child, and a pusher head facing the contact point with the guide member side is movable in the mover in the forward and backward direction of the mover. The pusher head is connected to the elastic member and biases the pusher head toward the guide member. When the mover is at the maximum distance from the guide member, Characterized by comprising a distance to a contact point to the the end guide member side as a short positional relationship than the maximum movement amount of the moving element.

In such a structure, the pusher head may be provided with a pressing means which constantly applies a pressing force to the guide member side at the end portion facing the guide member side.

The handle is hollow on the side facing the liner, and the mover is provided with a housing that can be inserted in a cartridge type in the hollow portion of the handle as an outer shell member and restrains the housing from rotating about its axis with respect to the liner. The cam mechanism is composed of a cam surface formed on the end surface of the housing in the insertion direction into the hollow portion of the handle, and a cam member provided inside the handle and having a sliding relationship with the cam surface. It may be one.

The cam surface of the cam mechanism has a profile of a combination of a stopper groove which is shallowly arcuate from the end surface and a flank which is deeper than the stopper groove and has a large circumferential length. A cylindrical cam shaft having an outer diameter substantially equal to the inner diameter of the circular arc of the stopper groove and having an axis line orthogonal to the moving direction of the moving element can be used.

Further, the cam surface is formed in an annular shape along the outer peripheral edge of the end surface of the housing of the moving element, and the stopper grooves are provided at two positions which are opposed to each other in the radial direction, and the clearance surface is provided between these stopper grooves. The cam shafts may be formed so as to be coaxial with each other so as to be rotatable about the axis, and each of them may independently have a sliding relationship with the stopper groove and the flank.

[0016]

BEST MODE FOR CARRYING OUT THE INVENTION The pusher head provided on a moving element has a moving amount of the moving element and a distance to a contact point between the pusher head and the guide member side when the moving element is separated from the guide member side by the maximum amount. Due to the above relationship, no pressing force is applied to the guide member. During this period, the support tool is unlocked with respect to the guide member side, and the support tool can be moved following the guide member.

When the mover approaches the guide member side,
After the pusher head hits the guide member side, the elastic means deforms in the direction opposite to the urging direction of the pusher head, and the elastic reaction force at this time strongly pushes the pusher head toward the guide member side, thereby supporting the guide member against the guide member. Is fixed.

In the pusher head provided with the pressing means, the pressing force to the guide member side is always applied even when the lock is released. Therefore, the pressing force restrains the support tool to the guide member side and Prevents slipping off.

In the cartridge type moving element,
The cam mechanism can be configured with the cam member of the handle simply by providing the cam surface on the end surface of the housing of the outer casing, and it is possible to reduce the size by consolidating the lock and unlocking mechanism on the handle side. Becomes

In the case where a stopper groove and a clearance surface are formed on the cam surface and the cam member is a cylindrical cam shaft, the cam shaft faces the clearance surface when the lock is released, and is attached when locking. The cam shaft is fitted in the stopper groove while the reaction force of the biasing means increases. Therefore, at the time of the lock operation, it is possible to obtain a click operation by dropping the cam shaft into the stopper groove, and a reliable lock operation can be performed due to a feeling of feeling when the handle is operated.

Further, in the case where the cam surface is annularly formed on the end surface of the housing of the moving element, the stopper groove and the clearance surface are provided at each of two places, and the cam shaft is also provided at two locations on the same axis, the handle is rotated. When this is done, the rotation directions of the cam shafts that are in sliding contact with one set of the stopper groove and the flank and the other set are opposite to each other. Therefore, if the two cam shafts are combined and are rotatable about their axes, sliding between the cam surfaces is smooth and a light operation is possible.

Is coaxially joined to the liner 4 and is connected to the liner 4 so as not to rotate about its axis. In addition, the pusher head 6c is provided which has a base end housed in the housing 6a and whose distal end is projected from the end face of the housing 6a. The pusher head 6c is biased to the right in FIG. 4 by a biasing spring 6d provided as an elastic means in the housing 6a, and a compression pressing spring is provided in a bore 6e provided in a portion protruding from an end surface of the housing 6a. 6f is incorporated as a pressing means. The outer circumference around the bore 6e has an outer shape that can be inserted into the connecting hole 4b of the liner 4, and the pressing spring 6f has a length protruding beyond the bore 6e when no load is applied.

A cam surface 6g having a shape as shown in FIG. 7 is provided on the end surface of the pusher head 6c on the base end side. FIG. 8 shows the details of the cam surface 6g. FIG. 8A is a front view of the cam surface 6g side, FIG. 8B is an end plan view of FIG. (C) is a longitudinal sectional view taken along the line C-C of FIG.

The cam surface 6g is formed near the outer peripheral edge of the end surface of the pusher head 6c, and shallow stopper grooves 6h and 6i are provided at both upper and lower ends thereof, and a circle is formed between these stopper grooves 6h and 6i. The flanks 6j, 6 which are recessed in an arc shape

The handle 5 is a hollow body integrally provided with a lever 5b protruding in the radial direction and having an open end surface on the annular groove 5a side. Then, two cam shafts 9 and 10 are provided at the innermost part of the handle 5 so as to have a rotation axis that coincides with the extending direction of the lever 5b.
These cam shafts 9 and 10 are common parts made of a metal cylindrical body, and are formed in the handle 5 as shown in FIG. 9 which is a front view of the handle 5 viewed from the joining side with the liner 4. It is inserted between the two ribs 5c and is rotatable about its axis.

As shown in FIG. 4, the moving element 6 is coaxially incorporated into the handle 5 incorporating the cam shafts 9 and 10, and the liner 4 is connected by the engaging projection 4e. As described above, the engaging protrusion 4e is provided on the handle 5
The liner 4 and the handle 5 are coaxially rotatable with each other because they are simply inserted into the annular groove 5a formed on the end face side. The mover 6 incorporated in the handle 5 has the two projections 6b formed on the end face thereof fitted into the cutouts 4d formed in the end face of the liner 4, so that the mover 6 can be positioned around the axis of the mover 6 with respect to the liner 4. Is fixed.

That is, if the line segment connecting the notch 4d is orthogonal to the opening axis of the through hole 4a of the liner 4,
The posture of the projection 6b of the mover 6 is also in the same orthogonal relationship. Therefore, the cam surface 6g of the mover 6 is shown in FIG.
As shown in FIG. 7, the stopper grooves 6h and 6i are positioned in the vertical direction so that the stopper 6 is incorporated into the handle 5, and the mover 6 is restrained from rotating about its axis.
Only the handle 5 can be rotated about the axis with respect to the liner 4.

The support 2 is attached to the guide pipe 1 by
As shown in FIG. 5, the hanger 3 and the handle 5 are connected to both ends of the liner 4 on which the cover 8 is inserted, and the through hole 4
The slide ring 7 is inserted into a and 8a, and the slide ring 7 is externally inserted into the guide pipe 1. At this time, the tip of the bore 6e of the pusher head 6c of the mover 6 is moved from the communication hole 4b to the communication hole 8b.
Since it projects into a, it is pushed back into the handle 5 so as not to interfere with the insertion of the slide ring 7.

In the above structure, when the handle 5 of the support tool 2 is in the posture shown in FIG. 4, the cam shafts 9 and 10 are in contact with the stopper grooves 6h and 6i of the cam surface 6g. At this time, the mover 6 is displaced to the guide pipe 1 side by the maximum amount in FIG. 2, and the end surface of the bore 6e at the tip of the pusher head 6c abuts the outer peripheral surface of the slide ring 7. The pusher head 6c is urged by the urging spring 6d in a direction to push the slide ring 7, and the pressing spring 6f such as the bore 6e also pushes the slide ring 7 at the same time.

As described above, the pusher head 6c is pressed by the biasing spring 6d at the same time as the pressing spring 6f.
The slide ring 7 is pressed by the composition of the urging force due to. As a result, the support tool 2 is firmly fixed to the guide pipe 1 on which the slide ring 7 is inserted via the pressing force of the pusher head 6c.

When adjusting the height of the support tool 2, the lever 5b of the handle 5 is pushed toward the front or the back side in FIG. At this time, since the mover 6 cannot rotate about the axis with respect to the liner 4 as described above, the handle 5
Only the rotating. When the lever 5b is pushed to the back side, the mover 6 has a positional relationship of rotating counterclockwise with respect to the handle 5 in FIG. 8A.
The flanks 6j and 6k overlap with the cam shafts 9 and 10, respectively.

On the other hand, as shown in FIG. 8C, the cam surfaces 6j and 6k are deepest in the vicinity of the stopper grooves 6h and 6i at an angle of 90 degrees.
When the engagement with the stopper grooves 6h and 6i is released, the handle 5 is held in the posture rotated by 90 degrees as shown in FIG. That is, when the handle 5 is pushed, the cam shafts 9 and 10 need to be pulled out from the stopper grooves 6h and 6i.
It is possible to move the entire mover 6 to the right side in FIG. When the arcuate curved surfaces of the flanks 6j and 6k and the camshafts 9 and 10 are brought into correspondence with each other, the biasing spring 4d is restored and finally stops in the posture shown in FIG. 6 remains at the position farthest from the guide pipe 1.

In FIG. 10, the pusher head 6c of the mover 6 is in a stopped state at the position where it hits the inner wall of the housing 6a by the urging spring 6d.
The protrusion length to the tip surface forming e is the maximum. Therefore, the tip of the bore 6e side is the slide ring 7
If the length is set so as to be slightly away from the peripheral surface of the slide ring 7 by the pusher head 6c as shown in the figure,
However, only the pressing spring 6f protruding from the bore 6e presses the slide ring 7.

As described above, the slide ring 7 is only restrained by the pressing spring 6f, the lock on the guide pipe 1 is released, and the support 2 can be moved up and down along the guide pipe 1 to adjust the height. After this position adjustment, the lever 5b of the handle 5 is tilted to the back side, so it is returned to the original posture in FIG. 4 or pushed downward.

For example, when returning to the posture shown in FIG. 4, the cam shafts 9 and 10 abutting on the flanks 6j and 6k roll on the flanks 6j and 6k in accordance with the rotating direction of the handle 5, so that the housing 6a. Is gradually pushed to the right side in FIG. 10, and the urging spring 4d is contracted and deformed accordingly. When the cam shafts 9 and 10 are aligned with the stopper grooves 6h and 6i, respectively,
As shown in FIG. 4, the tip surface of the bore 6e of the pusher head 6c abuts on the slide ring 7. As a result, the elastic reaction force due to the contracting deformation of the urging spring 4d also increases, and the rotation of the handle 5 is locked when the cam shafts 9 and 10 fall into the stopper grooves 6h and 6i, and at the same time, the pusher head 6c slides. By pressing 7 the support 2 is again fixed to the guide pipe 1.

As described above, the fixing of the support 2 to the guide pipe 1 and the release of the lock are performed by the cam surface 6g and the cam shafts 9 and 1.
The stroke of the moving element 6 and the movement of the pusher head 6c connected to this are combined. Since the pusher head 6c is connected to the moving element 6 by a biasing spring 6d which contracts in the stroke direction of the moving element 6, the stroke of the moving element 6 by the cam surface 6g and the cam shafts 9 and 10 is increased. Also, the biasing spring 6d buffers the pressing force of the pusher head 6c on the guide pipe 1 side. Therefore, an excessive pressing force does not act on the guide pipe 1 from the mover 6, and the operation of the handle 5 does not become heavy.

Even if the stroke of the mover 6 is large, it does not affect the operation. Therefore, even if the shape of the cam surface 6g and the dimensional accuracy and the assembly accuracy of each member are not made strict, the rotation of the handle 5 by the urging spring 6d is prevented. By utilizing the buffer during the operation, it is possible to maintain a stable fixation with respect to the guide pipe 1. Further, the urging spring 6d can be used against the change with time due to wear of each member.
By utilizing the absorption of size and shape changes due to
Stable usability is maintained.

Furthermore, even when the lock of the guide pipe 1 by the mover 6 is released, the support tool 2 is loosely restrained with respect to the guide pipe 1 by the elastic force of the pressing spring 6f incorporated in the mover 6. . For this reason, even if the lock is released, the support tool 2 does not suddenly slip off and can be used safely. Further, by arranging such a mechanism for preventing the fall together on the side of the moving element 6, it is possible to reduce the size and weight of the support tool 2 and further improve the usability.

[0055]

According to the present invention, since the pusher head for exerting a pressing force on the guide member side is biased by the elastic means of the moving element, when the handle is rotated to lock or unlock the pusher head, elastic force is exerted. The resistance load of the cam mechanism can be converted to the contraction of the means, and the movement of the handle becomes lighter and the usability is improved as compared with, for example, the case where the cam surface directly abuts the guide member as in the prior art.

Since the elastic means can give a degree of freedom to the movement amount of the pusher head, the operability is not affected even if the dimensional accuracy and the assembly accuracy of each member are not strictly set. Management of parts and assembly work are also easy.

Further, since the pressing means for constantly exerting a pressing force on the guide member side is provided in the cartridge type moving element throughout the unlocking period, a mechanism for locking and slipping can be integrated on the handle side. The size and weight of the support can be reduced, and the usability is further improved.
