| (54) | Name bearing plate with locking elements for quickly locking outer push-buttons |
| (57) The present invention relates to a name-bearing plate including locking elements
for quickly locking outer push-buttons, which comprises a plate body having a plurality
of windows for name bearing glass elements, with adjoining holes for push-button elements. The main feature of the invention is that the name bearing glass elements define quickly coupling means for locking the body of the push-button. |
BACKGROUND OF THE INVENTION
[0001] The present invention relates to a name bearing plate with locking elements for quickly locking outer push-buttons.
[0002] As is known, in making brass name bearing plates great difficulties are at present encountered for coupling the ring push-buttons, which are also conventionally made of a brass material.
[0003] Actually, it is conventionally necessary to assemble several component elements by screw-type of connections, which have a comparatively high cost and require a comparatively long assembling time.
[0004] Moreover, problems are frequently encountered in performing a proper electrical insulation, since it is necessary to adopt specifically designed insulating processes.
SUMMARY OF THE INVENTION
[0005] Accordingly, the aim of the present invention is to overcome the above mentioned drawbacks, by providing a name bearing plate construction with means for quickly locking outer push-buttons, and in particular affording the possibility of performing, in a brass name bearing plate, a snap coupling of the outer push-button, without the need of using assembling tools or instruments.
[0006] Within the scope of the above mentioned aim, a main object of the present invention is to provide such a name bearing plate in which the electrical insulating operation can be performed in a very simple manner, thereby solving all of the related electrical connecting operation problems.
[0007] Another object of the present invention is to provide such a name bearing plate construction which, owing to its specifically designed configuration, is very reliable and safe in operation.
[0008] Yet another object of the present invention is to provide such a name bearing plate construction, including locking means for quickly locking the outer push-buttons, which can be easily made starting from easily commercially available elements and materials and which, moreover, is very competitive from a mere economic standpoint.
[0009] According to one aspect of the present invention, the above mentioned aim and objects, as well as yet other objects, which will become more apparent hereinafter, are achieved by a name bearing plate construction, with locking means for quickly locking the outer push-buttons, comprising a plate body having a plurality of windows for the name bearing glass elements adjoining push-button holes, characterized in that said name bearing glass elements define quick coupling means for locking the body of the push-button.
BRIEF DESCRIPTION OF THE DRAWINGS
[0010] Further characteristics and advantages of the present invention will become more apparent hereinafter from the following detailed disclosure of a name bearing plate construction with locking means for quickly locking the outer push-buttons, and being illustrated by way of an indicative, but not limitative example, in the accompanying drawings, where:

DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0011] With reference to the number reference of the above mentioned figures, the name bearing plate construction with locking means for quickly locking the outer push-buttons according to the present invention, which has been generally indicated by the reference number 1, comprises a brass material plate, which is provided with a plurality of windows 3, which can be arranged in an adjoining mutual relationship, by pairs, or which can be provided as single mutually superimposed elements.
[0012] At the windows 3, a name bearing glass element, generally indicated by the reference number 10, is coupled, which element can be either of a double type, as shown in figures 3 to 5, or of a single type, as shown in figures 6 and 7.
[0013] Each name bearing glass element defines an increased thickness region 11, which engages within the windows 3 and being provided with longitudinal side edges 12 having coupling tooth elements 13, in order to allow sheet element restraining elements 15 to be engaged therein, said restraining element 15 being provided with lugs 16 to be arranged between the tooth elements 13 for allowing application and removal operations to be easily performed.
[0014] Adjoining the windows 3 are provided a plurality of holes, indicated by the reference number 18, in which push buttons, generally indicated by the reference number 20, can be engaged.
[0015] More specifically, the push-buttons 20 have a hollow push-button body 21 in the inside of which a slider 22 is provided, also made of a brass material, and being connected to one end of a pin element 23 provided, on end arm portions 24 thereof, with a ring like enlarged portion 25 snap engaging inside an annular groove 26 as formed on the slider.
[0016] A spring 27 is moreover provided for operating between the push-button and innert bottom of the push-body 21.
[0017] The push-body 21 is provided, on the outer surface thereof, with a cut-out 30 being delimitated by an abutment element 31.
[0018] In the cut-out 30 quick connecting means can be engaged, said quick connecting means being defined by the glass elements 10 and comprising resilient tongues 35 engaging in the cut-out 30 and abutting against the abutment element 31 thereby allowing the push-button 20 to be quickly and easily locked inside the plate 2.
[0019] From the above disclosure it should be apparent that the invention fully achieves the intended aim and objects.
[0020] In particular, the fact is to be pointed out that the push-button can be easily connected and locked by simply engaging the push-button body 21 inside the tongues 35, which in turn engage in the cut-out or groove 30 thereby providing a firm locking.
[0021] To the foregoing it is to be added that also the push-button can be quickly and easily assembled since said pin can be coupled to said slider by a simple pressing operation; the latter will cause the arm elements 23 to be deflected, so as to cause the enlarged portion 25 defined at the end parts of said arms of said pin to be easily engaged in the groove 26 of the slider.
