Shower head

Abstract: A shower head comprising an insert (7) which is suitable to make the cap (6) that covers the monolithic assembly formed by a button (5a) and a return lever (5b) for the actuation of the device for switching from a central jet to a peripheral jet and viceversa appear to be divided into two portions: one (6a) which lies above the button (5a) and one (6b) which lies above the return lever (5b).

Description: The present invention relates to a shower head. Conventional shower heads, particularly used in kitchen sinks, are provided with an outer shell which is shaped so as to form a tubular portion which acts as a handle and contains an elongated insert having, at one end, a threaded portion for connection to a water feed duct, and connected at its other end to a cylindrical insert which is contained in a head-shaped portion of the shell and is locked therein by a plug provided with openings for the outflow of the water which are suitable to selectively form a central jet and a peripheral jet. Said cylindrical insert contains the device that provides switching from a central jet to a peripheral jet and viceversa and comprises, as means for its actuation by a user, a button and a return lever which are monolithically associated and are covered by a single cap made of elastic material which is associated with the outer shell. Pressing the button when the water flows out as a central jet produces switching to a peripheral jet; the return lever is pressed in order to return to the central-jet condition. Covering the monolithic assembly formed by the button and by the return lever with a single cap is certainly economical in terms of construction and assembly and produces an aesthetically pleasing situation. Accordingly, this constitutes an improvement with respect to equally known solutions in which the presence of two buttons which protrude separately from the shell leads to constructive complications, is unaesthetic and triggers dirt deposits. However, it also entails a drawback, namely the uncertainty that it produces in the user in terms of determining the exact point to be pressed in order to actuate the button or, as an alternative, the return lever, since no precise indications in this regard are given. It should also be noted that conventional shower heads have a handle with a smooth surface, which as such provides a possibly unsteady grip, or has a surface provided with large raised portions, which become regions where dirt deposits easily. A shower head with a single cap made of elastic material is disclosed by US-A-5 383 604. The aim of the present invention is to provide a shower head in which the characteristics of low cost, aesthetic pleasantness and cleanliness observed in known single-cap embodiments are preserved, eliminating the uncertainties in the actuation of the device for switching from central jet to peripheral jet and viceversa that are found in the above prior art. Within the scope of this aim an object of the present invention is to provide a shower head whose handle is suitable to provide a safe grip and is free from regions where dirt can deposit easily. This aim, these objects and others which will become apparent hereinafter are achieved by a shower body according to the invention, which has the features set forth in claim 1. The shower head according to the invention is also characterized in that it comprises at least one insert made of soft material which is accommodated in a corresponding opening formed at the handle. Further characteristics and advantages of the present invention will become apparent from the following detailed description of a shower head, illustrated only by way of non-limitative example in the accompanying drawings, wherein: Figure 1 is a sectional side view of the shower head according to the present invention, taken along a longitudinal plane; Figure 2 is a perspective view of the outer shell of the shower head of Figure 1; Figure 3 is a top view of the outer shell; Figure 4 is a sectional view, taken along the plane IV-IV of Figure 3; Figure 5 is a sectional view, taken along the plane V-V of Figure 3; Figure 6 is a perspective view of the cap of the shower head; Figure 7 is a longitudinal sectional view of the cap; Figure 8 is a perspective view of the insert of the shower head; Figure 9 is a transverse sectional view of the insert; Figure 10 is a perspective view of the cluster of inserts accommodated in the openings provided in the handle. With reference to the above figures, the reference numeral 1 generally designates the outer shell of the shower head, which comprises a tubular portion 1a, which acts as a handle, and a head 1b. The tubular portion 1a and the head 1b are mutually connected. An elongated insert 2 is provided in the tubular portion 1a and has, at the end that protrudes from the shell 1, a threaded portion for connection to a water supply pipe and is associated, at its other end, with a cylindrical insert 3 which is accommodated in the head 1b and is locked therein by a plug 4, which is provided with water outflow openings suitable to selectively form a central jet and a peripheral jet. The cylindrical insert 3 contains a device that provides switching from central jet to peripheral jet and viceversa. The device comprises, as means for actuation by a user, a button 5a and a return lever 5b, which are monolithically associated in a single assembly. By pressing the button 5a in the position shown in dashed lines, which makes the water flow out as a central jet, switching to a peripheral jet is performed; to return to the central-jet condition the return lever 5b must be pressed. All this occurs in a known manner. An important characteristic of the present invention is the fact that the monolithic assembly formed by the button 5a and by the return lever 5b is covered by a cap made of elastic material, generally designated by the reference numeral 6, which is inserted in a suitable seat formed in the shell 1 and is surmounted by a rigid insert 7, which is connected to the shell 1, so that the user sees it divided into two portions: a portion 6a, which lies above the button 5a, and a portion 6b, which lies above the return lever 5b. More specifically, the rigid insert 7 lies within a seat 6c which is provided in the cap 6 between the portions 6a, 6b and has such a depth as to provide continuity, as shown in Figure 1, between the surfaces of the insert 7 and of the cap 6. In order to provide connection to the outer shell 1, the insert 7 has feet 8 and 9 with end protrusions 8a, 9a which, by passing through corresponding openings 6d, 6e formed in the cap 6, enter holes 10 and 11 formed in the shell 1, with a snap engagement of the protrusions 8a, 9a on raised portions 10a, 11a provided at the ends of the holes 10 and 11. This configuration of the means for connecting the rigid insert 7 to the outer shell 1 is particularly advantageous at the construction level, especially because of the possibility to provide the through holes 10 and 11 in the shell 1 allowed by the particular characteristic of the cylindrical insert 3 of being waterproof; this characteristic is the subject of a patent application in the name of this same Applicant. In any case, it is evident that various different embodiments of said connection means are possible. The insert 7 may also be connected directly to the cap 6. The definition, performed by the insert 7, of the two cap portions 6a, 6b arranged respectively above the button 5a and above the return lever 5b allows the user to have a precise indication as to the method of actuation required to achieve the intended switching from central jet to peripheral jet and viceversa. A situation which can be obtained easily from the constructive point of view and has a good aesthetic value is also achieved. It should also be noted that the described insert 7 is advantageously made of a rigid material and that it also has dimensions which allow to provide thereon differentiated identification markings, thus sparing the manufacturer the need to apply the markings on the outer shell, with consequent inventory problems. Another important characteristic of the invention is the presence of inserts 12, 13 and 14 made of soft material, which are joined in a cluster by bands 15 and 16 and are inserted in openings 17, 18 and 19 which lie transversely to the handle at the portion of wall that is directed towards the water outlet region. The inserts 12-14 protrude slightly from the corresponding openings 17-19, are arranged so as to be substantially continuous with the surrounding wall, so that the user perceives their presence by touch mainly by virtue of the differentiation of the material, and are extended towards the inside of the handle so as to make contact with the elongated insert 2 provided therein and be locked thereby. It is understood that the described inserts 12-14 made of soft material may assume different shapes.
