DE2423362A1 - Face for church tower clock - is made from glass fibre reinforced plastics and is constructed to resist weathering - Google Patents

Abstract

The clock face comprises a glass fibre reinforced plastics disc, and with peripheral numbers around the clock face of the same material. A retaining ring holds a number of superimposed alternating epoxy-hardened layers and glass fibre layers together, each layer being in the form of an annular ring surrounding the central plastics disc, which is pref. formed with a homogenous filling between two plastics cover plates. The numerals for the clock face are defined by a glass front plate extending over the whole clock face and with different coloured zones. The numbers may be of roman or arabic form and can be provided in any colour.

Description

Title: Dial for church tower clocks with pointer Area of application: The invention relates to a dial for church tower clocks with a predetermined coating of synthetic resin and fiberglass fabric with plastic disc covering with laid out Digits, especially for facilities exposed to extreme weather conditions are.

Purpose: Such dials require a long shelf life, on the one hand, a point that is still far away from being recognized in broad daylight The digits enable and the other hand ensure that they do not rust and it is no longer necessary to color the front and the digits applies. The recognizability of the digits and the durability of the dials must be able to be guaranteed for years to come.

Prior Art: It is known to meet these needs Sheet metal dials connected with a riveted iron ring with bracing on the inside are made, which often after a few years despite a sufficient number of layers of paint start to rust.

In order to improve the durability, especially of dials for church tower clocks to be able to ensure, depending on whether the guarantee for the durability of the dials Has been granted for 5 or 10 years, it is also known that in individual areas use different weathering phenomena.

It is known that the dials made of polyester in individual Types were made, but the digits had to be attached with color.

Criticism of the state of the art: It is, however, necessary to have a Apply a multitude of coats of paint, each of which will wear through after several years Release the effects of rain and snow.

Object: The invention is based on the object that for dials no more paint needs to be used, thus extending the service life of the dials to be able to guarantee for church tower clocks for years.

Solution: According to the invention, this object is achieved in that the Dial made of a retaining ring and several layers of synthetic resin and fiberglass on a plastic disc covering, which is made for itself and in each case the digits be punched out to replace them with black plastic made of the same material, so that a smooth surface can be achieved.

Further embodiment of the invention: To have such a dial that is put together for a specific system in a simple manner To be able to assemble auxiliary workers are, according to a further embodiment of the invention, the plastic disc covering with punched out and re-laid out digits and the retaining ring is provided with resin and fiberglass layers to create a homogeneous finish.

Achievable Advantages: The advantages achieved with the invention exist especially in the fact that instead of a multitude of different layers of paint only a plastic retaining ring and a plastic disc covering with laid out digits must be made.

The most favorable composition of the resin and fiberglass layers replace an iron ring riveted to sheet metal with internal bracing.

Exemplary embodiments: exemplary embodiments of the invention are shown in FIG Drawing shown and are described in more detail below.

Sheet 1. Plastic disc covering with laid out digits. And punched out Numbers made of the same material only in black, so a smooth one Surface can be achieved.

Sheet 2. Retaining ring with homogeneous filling made of synthetic resin and fiberglass fabric. All parts are evenly and homogeneously connected. Numbers optionally in all colors. In Roman or Arabic version.

Claims (2)

PATENT CLAIMS: Generic term: 1. Dial for church tower clocks with a given coating of synthetic resin and fiberglass fabric with plastic disc covering with laid out and punched out digits from the same haterial, especially for facilities that are exposed to extreme weather conditions. Characteristic part: Characterized by the fact that the dial made of a retaining ring and several layers of synthetic resin and fiberglass fabric on one Plastic disc covering with laid out digits all parts were connected homogeneously. 2. dial and pointer according to claim 1 and 2 characterizing part of the dependent claim: Characterized in that the digits and the associated plastic covering were punched out of one and the same material and unmistakably join together the digits are provided. Pointer to the dial made of synthetic resin with fiberglass fabric made of several Layers poured in a negative mold. Shown in drawing on sheet 5.
