Abstract

A method for fabricating metallic actuating plates has metal plates or strip fabricated by means of a cutting or milling machine with integral rear-face projecting edge beadings as an intermediate product of the actuating plate, and the plates (3) made by cutting or milling are provided with subsequent surface treatment. An independent claim is included for an actuating plate for flush-mounted water closet.

Description

The invention relates to a method for the production of metal actuating plates for flush-mounted sanitary cisterns, and such a metallic actuating plate with an integral, rear projecting edge collar.

In addition to the classic flush plates made of plastic, more and more flush plates for metal concealed cisterns are being used more and more today due to increased demands on comfort, feel and hygiene in both public and private areas.

Manufacturers of such metallic toilet and urinal flush plates are forced to offer many different design families to meet the individual taste of end users. A current design taste corresponding, often in demand design of such metallic actuation plates has a flat, as edged shape as possible.

In addition, it is now common practice to provide retailers with samples or dummies of toilet and urinal flush plates for attachment to busy sample surfaces in their exhibitions, so that end users can get an idea of the bathroom design before they buy. For this purpose, it is expedient if the back of the so-called "dummy actuator plate" is flat, so that this easily and easily can be screwed or glued to a continuous wall.

Among the known methods for the serial production of metallic actuator plates for sanitary flush-mounted cisterns include zinc die-casting with subsequent finishing by electroplating, deep drawing and punching of brass plates with subsequent finishing by galvanizing and deep drawing and punching of stainless steel sheets.

However, zinc die casting is relatively time consuming and requires relatively expensive tools. Flat surfaces and flat components can hardly or only with difficulty be produced by this known method. For the production of different sized or differently shaped actuator plates a corresponding number of differently shaped molds is usually required. When Zinkdruckgussspritzen of actuating plates achievable minimum wall thickness and minimum radii at the edges of the plate are relatively large, so far as the design options are limited. Furthermore, the surface design of zinc die-cast actuated actuator plates by galvanic methods is relatively expensive.

The deep drawing of brass sheets or stainless steel sheets requires relatively expensive tools, in turn, a corresponding number of different thermoforming tools is needed for the production of different sized or differently shaped actuator plates. By deep drawing the actuator plates at the edges achievable minimum radii are comparatively large, so that the relevant design options are also limited.

The present invention has for its object to provide a method for the production of metal actuating plates for sanitary flush-mounted cisterns with which such actuation plates can be produced relatively flat and substantially flat in a variety of designs, especially in particularly edged design cost.

This object is achieved by the method having the features of claim 1. Preferred and advantageous embodiments of the invention are specified in the subclaims 2 to 8.

The inventive method is essentially characterized in that from metal strip or metal plates, preferably made of aluminum strip or aluminum plates plate-shaped, an integral, rear protruding edge collar plates are milled as an intermediate for the actuator plates by means of at least one milling machine, the plates produced by milling then surface treated become.

By means of the method according to the invention, metallic actuation plates for WC and urinal concealed cisterns can be produced inexpensively in a variety of designs, in particular in a flat and angular design and with flat surfaces. The method according to the invention has no restrictions with respect to the shape design. in the Contrary to the known conventional methods, for example the deep-drawing of stainless steel sheets, rounded edges with minimum radii need not be accepted. Rather, the edges of the actuator plates with the inventive method can basically be formed arbitrarily sharp.

In particular, so-called "Dumany actuation plates" for sanitary exhibitions can also be produced cost-effectively with the method according to the invention.

As the starting material for the metallic toilet and Urinal Betätigungsplatten preferably aluminum strip and / or aluminum plates are used. Aluminum is easy to machine, is relatively inexpensive and only slightly susceptible to corrosion. After milling, and if necessary subsequent grinding and / or polishing, the workpieces can be provided with a hard, scratch-resistant surface by chrome plating or anodizing. The anodizing also allows a coloring of the aluminum surface, so that a variety of different designs can also be realized in terms of color.

An advantageous embodiment of the method according to the invention is characterized in that when milling serving as an intermediate plates elevations are generated at the rear, which are arranged within the integral, rear side protruding edge collar, and that in each of the elevations at least one threaded hole is incorporated. In the threaded holes can then, for example, with a corresponding Externally threaded mounting sockets or the like are screwed.

By virtue of this embodiment, relatively thin metal or aluminum strip can be used as starting material for the actuating plates. A milling of mounting sockets from the starting material of the actuator plates can thus be avoided. The starting material must therefore not have a thickness corresponding to the depth of the mounting bushes provided with actuating plate, the mounting bushes are then also milled out of the starting material with. The one-piece design of actuator plate and mounting sockets would require a correspondingly high material removal, which would mean unnecessary material or manufacturing costs.

Claim 9 is directed to a prepared by the process according to the invention metallic actuating plate for a concealed flushing cistern, which has an integral, rear projecting edge collar. Preferred embodiments of this actuator plate are specified in the subclaims 10 to 15.

The actuating plate 1 shown in the drawing comprises a viewing aperture 3 having a breakthrough 2 and a control element 5 having a pusher element 4, the pusher element 4 projecting through the aperture 2 with clearance and protruding with respect to the front side of the transparent screen 3. The screen 3 is plate-shaped and has an integral, rear projecting edge collar 6 (see. FIGS. 7, 8 and 14 ).

The screen 3 is made of metal strip, preferably aluminum strip or an aluminum plate (aluminum plate) milled. In the illustrated embodiment, the screen 3 is designed as a rectangular plate, the corners 7 are slightly rounded. The marginal edges (side edges 8 and transverse edges 9), however, are only slightly rounded. The Rounding of the peripheral edges 8, 9 has a radius of less than 2 mm, preferably less than 1.5 mm. For example, the radius of the rounding of the marginal edges 8, 9 is in the range of 1 mm to 0.2 mm, in particular in the range of 0.5 mm to 0.2 mm. The thickness of the screen 3 preferably corresponds to the initial thickness of the metal strip or the aluminum plate (aluminum plate).

The breakthrough 2 of the screen 3 is designed slot-shaped. It is arranged substantially horizontally at the average height of the screen 3. The two ends of the slot 2, which is also incorporated by milling in the screen 3, are semicircular.

In the back of the screen 3, a recess 10 in the form of a flat depression for receiving the plate-shaped control panel 5 is milled (see. Fig. 9 . 10 . 13 and 14 ). The recess (recess) 10 is formed substantially rectangular and has rounded inner corners 11, the radius of which is considerably larger than the radius of the outer corners 7 of the screen 3. The radius of the inner corners is for example 10 mm.

When milling the rear recess 10 of the screen 3 is formed or remains the integral, back protruding edge collar 6. In addition, the milling of the recess 10 recessed four circular areas of the workpiece, which finally form corresponding cylindrical elevations 12. In the arranged within the edge collar 6 elevations 12 each have a threaded bore 13 is incorporated. In these threaded holes 13 are then with a corresponding external thread 14 provided mounting bushes 15 screwed (see. FIGS. 5 to 8 ).

The fastening bushes 15 are, for example, turned parts made of metal or plastic.

After the screen 3 is made by machining, namely by milling aluminum strip or other semi-finished aluminum, it is fed as an intermediate surface treatment. The surface treatment may, in particular, comprise smoothing the viewing screen 3 by appropriate grinding and / or polishing.

Moreover, the method according to the invention provides that the plates (screens) 3 produced by milling and optionally ground or polished are chrome-plated or anodized. Before chrome plating or anodizing (anodic oxidation), the plates 3 produced by milling are first cleaned, so that the workpiece is free of grease and dust. For this purpose, the workpiece is washed, for example with sodium hydroxide solution (NaOH solution) or slightly pickled and then rinsed with distilled water.

The anodizing or chrome plating of the plates 3 takes place in a manner known per se and will therefore not be described in more detail here.

The anodization of the plates (screens) 3 may include, in particular, a coloring of the plates. Then be The panels are sealed to give them a hard, durable finish.

The plate-shaped operating part 5 has on the upper and lower longitudinal edge indentations 16, in which the elevations 12 engage on the back of the screen 3 with play. The strip-shaped pusher element 4 is releasably connected to the control panel 5 (see. Fig. 14 ).

The plate-shaped operating part 5 is associated with a mounting frame 17, on the power transmission means (not shown), e.g. Bowden cables or the like, are stored. The mounting frame 17 consists of a plastic injection-molded part and is mounted in an inspection opening of the concealed cistern or the concealed cistern receiving pretext. The mounting frame 17 includes an actuatable via the operating part 5 rocker mechanism (not shown), which acts on the power transmission means. The strip-shaped pusher element 4 is divided by a groove 18 into a shorter 19 and a longer section 20. The longer section 20 is associated with a power transmission means for triggering a full flush. On the other hand, by pressing the shorter section 19, a force transmission means for triggering a partial flush can be actuated.

The associated with the screen 3 mounting sockets 15 are formed in the front of the mounting frame 17 receptacles (not shown) associated, in which the mounting sockets 15 can be positively and frictionally inserted. In the lower portion of the edge collar 6 of the screen 3, a recess 21 is provided in the for releasing the screen 3 of the mounting frame 17, a corresponding tool can be inserted.

The embodiment of the invention is not limited to the embodiment described above. Rather, a variety of variants are possible, which make use of the inventive concept given in the claims even with fundamentally different execution. Thus, the actuator plate 1 according to the invention can be performed not only in the form of an elongated rectangle but also, for example, as a square or circular plate. Furthermore, the method according to the invention makes it possible to provide the peripheral edge 8, 9 of the screen 3 with a chamfer. The angle of the chamfer is preferably in the range of 30 ° to 65 ° and may in particular be 45 °.
