BACKGROUND OF THE INVENTION
[0001] The present invention relates to a name bearing plate, provided with quick locking
means for locking the outer push-buttons associated with said plate.
[0002] As is known, in making brass name bearing plate, a problem is that of properly coupling
to the plate the ringer push-buttons, which push-buttons are also made of a brass
material.
[0003] Actually, it is rather difficult to properly assembling a lot of component elements
by using screw connections which, moreover, are very expensive mainly from the assembling
time standpoint.
[0004] Moreover, a further problem is that of properly electrically insulating the ringer
push-buttons.
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 with locking means for quickly locking
outer push-buttons associated with said plate, which allows to make, on a brass name
bearing plate element, a snap type of coupling for connecting an outer push-button,
without using tools or the like.
[0006] Within the scope of the above mentioned aim, a main object of the present invention
is to provide such a name bearing plate which allows to perform electrically insulating
operations in a very simple manner, thereby solving all of the related problems.
[0007] Another object of the present invention is to provide such a name bearing plate which,
owing to its specifically designed construction, is very reliable and safe in operation.
[0008] Yet another object of the present invention is to provide such a name bearing plate,
including locking means for quickly locking outer push-buttons associated with said
plate, 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 provided with quick locking means for quickly locking outer
push-buttons associated with said plate, comprising a plate element having a plurality
of windows for receiving corresponding name bearing glass elements adjoining holes
for receiving said push-buttons, characterized in that said name bearing glass elements
define quick coupling means for locking a body of a said push-button.

with quick locking means for quickly locking outer push-buttons, which is illustrated,

DESCRIPTION OF THE PREFERRED EMBODIMENT
[0011] With reference to the number references of the above mentioned figures, the name
bearing plate, including quick locking means for quickly locking outer push-buttons
associated with said plate, according to the present invention, which has been generally
indicated by the reference number 1, comprises a brass plate, which is provided with
a plurality of windows or throughgoing openings 3, which can be arranged in a by pair
adjoining relationship, or which can be individual and overlaid one on the other.
[0012] In the mentioned windows or openings 3, is engaged a name bearing small glass element,
generally indicated by the reference number 10, which can be either of a double type,
as is shown in figures 3 to 5 or of a single or individual type, as is shown in figures
6 and 7.
[0013] Each name bearing glass element defines an enlarged thickness region 11 engaging
inside the windows 3 and being provided with longitudinally extending side edge portions
12 provided with coupling tooth elements 13, for allowing name sheet restraining or
holding elements 15 to be engaged therein, each said name sheet holding element being
provided with fins or tabs 16 adapted to be engaged between said tooth element 13
for allowing said name bearing sheet holding element to be easily applied and removed.
[0014] Adjoining the windows 3 are provided a plurality of holes, indicated by the reference
number 18, in which can be engaged push-buttons, generally indicated by the reference
number 20.
[0015] More specifically, each push-button 20 is provided with a hollow push-button body
21, in the inside of which is provided a slider element 22, also made of a brass material,
which is coupled to an end portion of a pin 23, provided, on end arm elements 24 thereof,
with a ring-like enlarged portion 25, adapted to be snap engaged in an annular groove
26 formed on the slider element.
[0016] Between each push-button and the inside bottom portion of the push-button 20, is
arranged a spring 27.
[0017] As shown, the push-button body 20 is provided, on the outer surface thereof, with
a cut-out 30, delimited by an abutment 31.
[0018] In said cut-out portion 30, quick connecting means can be easily engaged, said quick
connecting means being defined by said small glass element 10 and comprising resilient
tabs 35, engaging in the cut-out portion 30 and abutting against the abutment 31,
thereby allowing the push-button 20 to be quickly and simply 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, it should be pointed out that the push-button is connected by simply
engaging the body of the push-button inside the tabs 35, which in turn engage in the
cut-out portion or groove 30, thereby providing a quick locking operation.
[0021] In this connection it should be moreover apparent that the push-button can be easily
assembled, since the push-button pin is coupled to the slider element by a simple
pressing operation, which causes the arms 23 to be bent, thereby causing the enlarged
portion 25 to be engaged in the groove 26 of the slider element, which enlarged portion
25 is defined, as shown, at the end portions of the arms of the push-button pin.
[0022] In practicing the invention, the used materials, provided that they are compatible
to the intended use, as well as the contingent size and shapes, can be any, depending
on requirements.
