Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a shower support made of synthetic resin in which a hose connected to a shower head passes freely and a base end of the shower head is detachably supported.

[Conventional technology]

As a support tool for supporting the shower head, a hanger type with a substantially U-shaped cross section fixed to the wall of the bathroom and a hose that is fixed to the ball rim of a vanity or hair washing machine so that the hose can pass through Some have a hollow structure.

FIG. 6 is a perspective view partially showing the washbasin, and the support 1 of the showerhead B is fixed to the center of the washbasin A on the back side. As shown in the cross-sectional view of FIG. 7, the support 1 is a tubular body, and the hose C connected to the base end of the shower head B can be freely inserted to withdraw the shower head B, and It is used as a means to fit and hold.

When viewed from the side into which the shower head B is inserted, as shown in FIG. 8, the support 1 has a planar shape close to an ellipse, and the cavity 1a through which the shower head B and the hose C are inserted has a circular cross section. . Thus, if the outer shape is elliptical and the cavity 1a is circular, FIG. 8 (b) (cross-sectional view taken along the line YY of FIG. 8 (a)) and FIG. 7 (FIG. 8). (A) ZZ
As is clear from a comparison with (corresponding to the position indicated by the arrow), the thickness of the left and right ends of the support 1 becomes larger than the depth in the front-rear direction.

By the way, in the case of a tubular product, when a part in the circumferential direction has a partially thick cross section, a sink mark occurs when the mold is released. The occurrence of such sink marks is remarkable when the mold is unmolded before the thick portion is completely cooled and solidified, and deformation such as denting of the outer surface is unavoidable, resulting in a failure to supply as a product.

When the hollow product has a non-uniform wall thickness as described above, it is necessary to prevent sink marks when the mold is manufactured.

[Problems to be solved by the device]

However, in addition to holding the shower head B, the shower head B is frequently taken in and out, so that the support 1 needs to have a corresponding strength. Therefore, the thickness is to be designed based on the thickness of the thin portions located on the left and right in FIG. 8 (a), and if synthetic resin is used instead of metal,
From the viewpoint of strength, it is necessary to further increase the wall thickness.

As described above, when the specification is changed from the metal product to the synthetic resin product, the influence of the wall thickness is further increased. Therefore, a product with a uniform thickness tends to be handled as the most suitable product shape, and the supply of products with few variations tends to occur all the time.

The problem to be solved in the present invention is to separately form two members and combine them to provide a good shower support that is not affected by the wall thickness of each member.

[Means for Solving the Problems]

The present invention relates to a shower support tool having a hollow structure for instructing a proximal end portion of a shower head to be freely inserted and removed. And an outer shell member made of synthetic resin, which are integrated with each other.

The peripheral walls around the hollow portion formed by the inner shell member and the outer shell member can be configured to have a substantially uniform wall thickness.

Further, an engagement claw capable of elastically deforming in the radial direction may be provided on the outer circumference of the inner shell member, and an engagement groove into which the engagement claw can be fitted may be provided on the inner circumference of the inner shell member.

[Action]

Due to the combination of the inner shell member and the outer shell member made of synthetic resin, the difference in the wall thickness when viewed from the whole support tool is halved for the respective inner shell and outer shell members themselves. For this reason, the difference in wall thickness between the inner shell and the outer shell member becomes small, and the occurrence of sink marks when molding these members is suppressed.

By setting the peripheral walls of the inner shell and the outer shell members to have substantially uniform wall thicknesses, the occurrence of sink marks can be prevented even better.

Further, since the engaging claws of the inner shell member are elastically deformable in the radial direction, the engaging claws are fitted into the engaging grooves of the outer shell member to be joined only by pushing the inner shell member into the outer shell member. .

〔Example〕

Hereinafter, the features of the present invention will be specifically described with reference to the embodiments shown in the drawings.

FIG. 1 is a sectional view of an example in which the shower support of the present invention is applied to the shower head shown in the conventional example.

In the figure, the support 1 is composed of a synthetic resin outer shell member 2 forming the entire surface and a synthetic resin inner shell member 3 inserted into the outer shell member 2 as well. The outer shell member 2 and the inner shell member 3 are shown in FIGS. 2 and 3, respectively. FIG. 4 is an integrated view and FIG. 5 is an exploded perspective view thereof.

The outer shell member 2, as shown in FIG. 2 (a), is a cylindrical body having a substantially elliptical planar shape, and is shown in FIG. 2 (b) (FIG. 2 (a)).
I-I line cross-sectional view) and the same figure (c) (of the same figure (a))
As shown in the sectional view taken along the line II-II), the inner peripheral wall has a total of 8
The book ribs 4 run in the axial direction. This rib 4
A straight part 4a parallel to the axis is formed on the upper side, and a taper part 4b having a surface inclined toward the center is formed on the lower side.
Further, a total of four engaging grooves 5 with which the lower end of the inner shell member 3 engages are provided at positions where the long axis of the ellipse is sandwiched in the planar shape. The engagement groove 5 is formed by the engagement groove 5 in FIG. 2 (d) (III in FIG.
As shown in the cross-sectional view taken along line III-III), the outer shell member 2 is formed by removing the inner surface of the peripheral wall.

Furthermore, the upper end of the rib 4 is one step lower than the peripheral wall, and the upper surface thereof is the mounting surface of the inner shell member 3. Further, by providing the rib 4, the wall thickness of the peripheral wall of the outer shell member 2 can be made substantially uniform. In other words, since the strength can be maintained by the ribs 4, it is not necessary to make the wall thickness thicker or thinner to match the hollow portion as in the conventional example, and the entire peripheral wall can be made uniform in thickness. .

On the other hand, the inner shell member 3 is formed with a flange 6 having a substantially elliptical outer shape that fits in from the upper end of the outer shell member 2 at the upper end, and a straight portion 4a of the rib 4 of the outer shell member 2 is formed at the lower portion thereof. A cylindrical portion 7 that fits in is provided. Further, below the cylindrical portion 7, there is formed a sleeve 8 which is fitted along the tapered portion 4b. The sleeve 8 is a tapered cylinder whose inner diameter on the lower end side contracts, and the inner peripheral taper is used to stably support the base end of the shower head B. The peripheral wall including the cylindrical portion 7 and the sleeve 8 is formed to have a substantially uniform thickness. Incidentally, FIG. 3 (b), FIG. 3 (c) and FIG.
FIG. 4 is a sectional view taken along line IV-IV, line V-V and line VI-VI in FIG.

Further, at the boundary between the cylindrical portion 7 and the sleeve 8, four engaging claws 9 for integrating with the outer shell member 2 are provided.
The engaging claw 9 is provided on the inner shell member 3 as shown in FIG.
The protrusion protrudes outward from the outer wall and extends downward, and an engaging projection 10 is formed at the lower end to fit into the engaging groove 5 of the outer shell member 2. The engaging claw 9 is aligned with the position of the engaging groove 5 shown in FIG. 2A, and the outer wall of the engaging claw 9 is made to fit the inner peripheral wall of the outer shell member 2.

When the inner shell member 3 is fitted into the outer shell member 2 in the above-described configuration, the support tool 1 by combining the two members is completed. The inner shell member 3 may be fitted in advance according to the posture of the outer shell member 2 and then pushed into the outer shell member 2 as shown in FIG. 4 (b), 4 (c) and 4 (d) are respectively VII-VII line and VIII-VII line in FIG. 4 (a).
It is sectional drawing by the I line and the IX-IX line arrow.

At the time of this pushing, the engaging claw 9 is elastically deformed inward by the engaging projection 10 that abuts against the inner wall of the outer shell member 2, and finally the flange 6 is placed on the upper surface of the rib 4 and at the same time the fourth
The engagement protrusion 10 is fitted into the engagement groove 5 as shown in FIG. In this way, the support 1 including the outer shell member 2 and the inner shell member 3 is assembled and can be used as a support for the shower head B as shown in FIG.

Here, the support 1 has a structure in which a surface orthogonal to the insertion direction of the shower head B is substantially oval and a circular cavity is provided at the center thereof, as in the case of the conventional example. Since the conventional example uses one member, there is a portion having a large wall thickness and a portion having a small wall thickness.

On the other hand, in the present invention, the two members of the outer shell member 2 and the inner shell member 3 are formed as a whole, and the wall thickness of each peripheral wall is made substantially uniform. The size of the thickness will be reduced to almost half. Therefore, even if the outer shell member 2 and the inner shell member 3 are made of synthetic resin, the problem of sink marks can be suppressed to a negligible level. Therefore, both the outer shell member 2 and the inner shell member 3 can be manufactured without deformation of the outer wall or the like. As a result, even with a structure in which two members are fitted together and integrated, a product with high accuracy can be obtained as with an integrated product. Further, since the outer wall is not deformed, the finish of the outer shell member 2 as a surface member is particularly good, and the yield is improved.

[Effect of device]

In the present invention, since the support is constructed by the combination of the inner shell member and the outer shell member made of synthetic resin, the difference in the wall thickness is halved for each of the inner shell member and the outer shell member, and the sink marks at the time of manufacturing the member are reduced. Is prevented from occurring.

Further, when the peripheral wall of each of the inner shell and the outer shell member has a substantially uniform thickness, the occurrence of sink marks is further improved.

Furthermore, by providing the inner shell member with the engaging claws and the outer shell member with the engaging grooves, the inner shell member can be joined only by fitting it into the outer shell member, and the assembly of two members is troublesome. Nor.
