Abstract

A method of making a shower head for a domestic shower installation includes the steps of forming a member 2 that is to provide the water jets, and perforating the member when in a substantially flat configuration whereafter, the perforated member is placed in a mould and the body portion 1 of the head is moulded around the member so as to produce a unitary structure. The body portion 1 is cylindrical and the member 2 is curved to conform to the cylindrical shape when placed in the mould. The member has a peripheral flange 4, which is incorporated into the wall of the cylindrical body portion. <IMAGE>

Description

Improvements in and relating to Shower Heads This invention relates to shower heads and has particular reference to shower heads for domestic shower installations.
Conventional shower installations for use primarily in the home have shower heads that comprise a perforated disc mounted in a body member that is usually so shaped as to be held comfortably in a user's hand or be mounted on a support that is fixed to the wall of the shower cubicle or bathroom in which the shower installation is located.
One form of shower installation for domestic use is described in UK Patent Application No. GB 9302867.8. The installation includes a shower head that is mounted on the base plate of the shower control unit and which has an arcuate-shaped perforated portion through which water issues.
Conveniently, such a shower head is moulded from a suitable plastics material but it is difficult to ensure that the perforations are accurately located and correctly orientated so as to ensure an acceptable spread and direction of water jets leaving the head.
That problem also arises in the more conventional form of hand-held shower head but in a less acute way because the perforated disc is of a flatter form than the arcuate-shaped portion referred to above and, consequently, it is easier to ensure that the perforations are correctly positioned and orientated.
Accordingly, it is an object of the present invention to provide a method of making the shower head that allows a more accurate control of the location and orientation of the perforations.
According to the present invention a method of making a shower head for a domestic shower unit comprises the steps of forming a member that will provide the water jets, forming holes in the member when in a substantially flat configuration to provide outlets for the water jets, placing the perforated member in a mould and forming a body portion of the shower head around the member in a manner such that a unitary structure is formed.
Preferably, the member and the body portion of the shower head are of a plastics material and both are formed by a moulding process.
By way of example only, an embodiment of the invention will now be described in greater detail with reference to the accompanying drawings of which: Fig. 1 is a transverse cross section of the embodiment, and, Fig. 2 is a longitudinal cross section of the embodiment.
The embodiment is suitable for use as part of the shower bar described in UK Patent Application No. GB 9302867.8 referred to above and which is referenced 20 in the drawings accompanying the Application.
The embodiment is in the form of a cylindrical body 1 with a portion 2 of its surface formed with perforations 3. As can be sen from Fig. 1, portion 2 extends over about one quarter of the curved surface of the body 1 and is located in an area of the body that is slightly recessed. The portion 2 is of a rectangular shape when viewed from above and is made in the flat as a single component by a moulding process, for example an injection moulding process.
Preferably, the portion 2 is of plastics material, for example ABS.
The perforations 3 are formed during the moulding process and because the portion is formed as a flat component, the perforations are easily and accurately located and orientated using conventional moulding techniques.
As is shown in the drawings, the portion 2 has a integral peripheral flange 4 which ensures that the portion is firmly anchored in the body 1 as will be described below.
Body 1 is also of a plastics material, for example ABS and is also manufactured by a moulding process, preferably injection moulding. The mould used is adapted to allow the insertion of the portion 2 into the mould in the curved shape shown in Fig. 1, after which the body 1 is formed around the portion.
During the moulding of the body 1, plastics material flows around the peripheral flange 4 and so ensures that the portion 2 is securely located and held in the body 1. During the moulding of the body 1, the lateral extensions 5, 6 are formed. The extensions 5, 6 stretch along the full axial length of the body or almost so and each has a longitudinal recess 7 enabling the body to be pivoted as is described in the Patent Application referred to above.
The component shown in the drawings forms a part of the shower bar described in the Patent Application referred to above and, as described therein, is mounted upon a hollow spigot referenced 35 in that Application. In use, water is pumped into the interior of the spigot and emerges from the perforations 3.
The invention is also applicable to other forms of shower head than that just described. For example, it can be embodied in shower heads of the conventional form in which the perforated member is in the form of a flat or slightly convex disc.

Claims (8)

CLAIMS.
1. A method of making a shower head for a domestic shower installation comprising the steps of forming a member that will provide the water jets, forming holes in the member when in a substantially flat configuration, placing the member in a mould and forming a body portion of the shower head around the member in a manner such that a unitary structure is formed.
2. A method as claimed in claim 1 in which the member and the body portion are both of a plastics material.
3. A method as claimed in claim 2 in which the member and the body portion are both formed by injection moulding.
4. A method as claimed in any one of the preceding claims in which the body portion is formed as a cylinder, the member being curved to conform to the shape of the cylinder and being incorporated in the wall of the cylinder during the formation of the portion.
5. A method as claimed in claim 4 in which the wall is recessed round the member.
6. A method as claimed in any one of the preceding claims in which a peripheral flange is provided around the member during the formation of the latter.
7. A method as claimed in claim 6 when appended to claim 4 or 5 in which the flange is incorporated into the wall of the cylinder.
8. A shower head when made by the method as claimed in any one of the preceding claims.
