Title: UNIT FOR ATTACHING AND DISTRIBUTION OF MULTIMEDIA
PERIPHERALS
I. BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates, in general, to enclosures and receptacles
assemblies for wiring and
distribution and, more particularly, to an unit for attaching and distribution
multimedia
peripherals, destined especially for apartments in multi-dwelling buildings
and residential,
single-family homes.
2. Description of the Prior Art
There are known various enclosures for terminating wires from outlets and for
distribution in
residences wires for voice, data and video. Such enclosures are used in new
installations and
retrofits and can be surface-mounted or recessed. The disadvantages of the
aforementioned
enclosures reside in the limited positioning possibilities for the
electric/electronic components, in
the limited reliability of the attachments of components and in no secure
closure of the
enclosures.
Attempts have been made to eliminate or at least to alleviate the foregoing
shortcomings. For
example,United States Patent No.8,680,407, granted on March 25, 2014 to Chan
for a "Modular
Enclosure Assembly for Terminals Wiring and Distribution" discloses an upper
and a lower
enclosure subassemblies interconnected by a partial interpenetration. That
assembly is designed
to enable extensions by combining adjacent subassemblies and is intended for
use in large
companies and offices, in multi-apartments buildings and in factories.
II. SUMMARY OF THE INVENTION
1
CA 02864529 2014-09-25
A first objective of the unit for attaching and distribution multimedia
peripherals, according to
the present invention, is to devise a compact unit that accommodates therein
the positioning of
electric/electronic components of different sizes and configurations;
A second objective of the present unit is to eliminate the usual attachments
of components via
cable ties, which are are not re-usable, and to replace them by clasping-
escaping devices; and
A third objective of the present invention is to provide an unit that can be
secured to a wall, or
stand on a pedestal, and can be locked to preempt an unwanted access therein.
Based on the above objectives, the inventors developed an unit for attaching
and distribution
multimedia peripherals which comprises an assembly for clasping-escaping and a
receptacle-
terminal assembly.
The assembly for clasping-escaping includes an L-shape subassembly comprising
a vertical wall
provided with backwards projecting, vertically spaced and inverted at 90 T-
beams used to
connect the L-shape subassembly to a parallelepipedic open box of the
receptacle-terminal
assembly. A bottom plate, centrally located at the lowest part of the vertical
wall and
perpendicularly disposed to the latter, extends outwardly. A passage starting
above the bottom
plate and formed in the lowest part of the vertical wall extends along the
whole length of the
bottom plate. A base of the passage ends, oppositely to the vertical wall, in
a pair of serrations. A
channel starting with an opening in the vertical wall is formed by opposite,
inverted at 90 U-
shape indentations, separated by a vertical continuation of the passage.
The clasping-escaping subassembly incorporates a vertically standing plate. A
fixed tongue
2
CA 02864529 2014-09-25
extending perpendicularly on and outwardly from the vertically standing plate,
while a flat bar,
which is coplanar with the fixed tongue, extendis perpendicularly on and
inwardly from the
vertically standing plate. The flat bar folds on itself at an end opposite the
vertically standing
plate and traverses the vertical wall. The flat bar has a width commensurate
with a width of
vertical continuation of the passage, i.e. is delimited by sides of the
channel. An easy-sliding fit
is established between sides of the channel and the flat bar. The flat bar,
after folding on itself in
a zone, extends into a diverging strip that incrementally distances from a
horizontal line starting
from the zone where the flat bar folds. The diverging strip is provided with a
multitude of
serrations, downwardly directed. The diverging strip ends forwardly, after the
multitude of
serrations, into a mobile finger pushing tongue.
The receptacle-terminal assembly includes the parallelepipedic open box
subassembly which has
a vertical, lateral access and an attaching cover. The parallelepipedic open
box subassembly
incorporates a rectangular frame provided with a rear base wall, a top and a
bottom elongated
strip plates and a left and a right lateral, elongated strip plates. A pair of
juxtaposed, horizontally
extending plurality of T profile protrusions is used. Each of the T profile
protrusion incorporates
a T profile elongated stem. A series of knurls disposed along, above and
underneath of each the T
profile elongated stem creates a friction between the T profile elongated
stems and the pair of
backwardly projecting, vertically spaced and inverted at 900 T-beams.
More specifically, in the foregoing unit, each of the pair of backwards
projecting, vertically
spaced and inverted at 90 T-beams forms a plain butt joint and has an
outwardly projecting
flange. Outwardly projecting flanges of the pair of backwards projecting,
vertically spaced and
inverted at 90 T-beams is used to connect the L-shape subassembly to the
parallelepipedic open
box subassembly of the receptacle-terminal assembly. The rear base wall
includes, in immediate
3
CA 02864529 2014-09-25
proximity of each of its vertical lateral extremity, a frontward projecting,
vertical elongated strip;
The rear base wall is defined by a longitudinal axis of symmetry and is
proximately flanked by
the frontward projecting, vertical elongated strips and each of the
horizontally extending
plurality of T profile protrusions extends vertically and successively, in
tandem.
More specifically, as well, the present unit further comprises a key hole
mounting bracket, which
constitutes an integral part, formed by a front vertical wall and a back
vertical wall. The front
vertical wall and the back vertical wall are horizontally spaced and laterally
interconnected and
at a bottom. The front vertical wall centrally comprises, starting from a top,
a triangular guiding
entrance aligned with and followed by a vertical slot. The back vertical wall
extends into the pair
of backwards projecting, vertically spaced and inverted at 90 T-beams used
for cooperating with
the parallelepipedic open box subassembly. A locating fixture, adaptable to
interconnect a part to
the key hole mounting bracket, includes a disc located behind the front
vertical wall and
extends into a split pin, provided with two forcibly squeezable prongs that
traverses the front
vertical wall. The split pin with two forcibly squeezable prongs is adaptable
to be engaged by
pressing it against an orifice of an electric/electronic component..

peripherals" is generally
designated with capital letter A.
Unit for attaching and distribution multimedia peripherals A comprises
- an assembly for clasping-escaping, generally designated with numeral 10,
intended for
positioning, size adjusting and retaining-releasing electric/electronic
components, including
- an L-shape subassembly 100 incorporating a vertical wall 105 provided with a
pair of
backwards projecting, vertically spaced and inverted at 900 T-beams 110; each
of the latter forms
a plain butt joint and has an outwardly projecting flange 115; the outwardly
projecting flanges
6
CA 02864529 2014-09-25
115 are used to connect L-shape subassembly 100 to a parallelepipedic open box
subassembly
300, detailed farther in the present specification; a bottom plate 120,
centrally located at the
lowest part of vertical wall 105 and perpendicularly disposed to the latter,
extends outwardly;
bottom plate 120 has its lateral margins 125 retracted from the transverse
extremities 130 of
vertical wall 105; a passage 135 starting above bottom plate 120 and formed in
the lowest part of
vertical wall 105 extends along the whole length of bottom plate 120; a base
of passage 135 ends,
oppositely to vertical wall 105, in a pair of serrations 140 having a saw like
appearance with,
backwardly directed, tooth like projections; a channel 145 starting with an
opening in vertical
wall 105 is formed by opposite, inverted at 90 U-shape indentations 150,
separated by a vertical
continuation of passage135;
- a clasping-escaping subassembly 200 incorporates a vertically standing plate
205.terminating at
its upper side by a folded back on itself portion 210 incorporating a
throughout aperture.215
adapted for inserting a cable tie (not shown) for a supplementary attachment
of electric/electronic
components with distinct sizes/shape or when a single clasping-escaping
subassembly 200 is
used; a fixed tongue 220 extends perpendicularly on and outwardly from
vertically standing plate
205, while a flat bar 225, which is coplanar with fixed tongue 220, extends
perpendicularly on
and inwardly from vertically standing plate 205; flat bar 225 folds on itself
at an end opposite
vertically standing plate 205 and traverses vertical wall 105; flat bar 225
has a width
commensurate with a width of vertical continuation of passage 135, i.e.
delimited by sides of
channel 145; an easy-sliding fit is established between sides of channel 145
and flat bar 225; flat
bar 225, after folding back in a zone 230, extends into a diverging strip 235,
that incrementally
distances from a horizontal line (not shown) starting from zone 230 where flat
bar 225 folds
back; back diverging strip 235 is provided with a multitude of serrations 240,
directed
downwardly and formed by forwardly directed teeth; diverging strip 235 ends

7
CA 02864529 2014-09-25
multitude of serrations 240, in a mobile finger pushing tongue 245, when an
electric/electronic
component is displaced and, then, captured between vertical wall 105 and
vertically standing
plate 205, the pair of serrations 140 is engaged with a corresponding number
of the multitude of
serrations; thus, a moderate force used to slide vertically standing plate 205
enables, via a
meshing of the pair of serrations 140 with a corresponding number from the
multitude of
serrations 240, to firmly secure an electric/electronic component to clasping-
escaping
subassembly 200, while a relatively greater force applied upwardly to mobile
finger pushing
tongue 245 circumvents the meshing; thus, gripping and locking of an
electric/electronic
component cease and an escapement of the latter results; an intermediary
elongated plate 250,
situated between flat bar 225 and diverging strip 235, is united in one body
with flat bar.225, and
is able to slide along channel 145, respectively in opposite, inverted at 900
U-shape indentations
150, which perform the function of bilateral sliding tracks;
said unit for attaching and distribution multimedia peripherals A further
comprises

lateral extremity 320, a
pair of frontward projecting, vertical elongated strip 323. Rear base wall 306
is defined by a
longitudinal axis of symmetry (not shown), proximately flanked by frontward
projecting, vertical
elongated strips 323. A pair of juxtaposed, horizontally extending plurality
of T profile
protrusions 326 is used; each one of the pair of juxtaposed, horizontally
extending plurality of T
8
CA 02864529 2014-09-25
profile protrusions 326 is located between a pair of vertical strips 323
situated proximately of a
lateral extremities 320 and another pair of vertical strip 323 situated in
proximity of above
mentioned longitudinal axis of symmetry. Each horizontally extending plurality

knurls 337 is to create
a supplementary friction between T profile elongated stems 329 and a pair of
backwardly
projecting, vertically spaced and inverted at 900 T-beams 110. Thus, a
positional stability of
assembly for clasping-escaping 10 with respect to receptacle-terminal assembly
30 is enhanced.
An outwardly open bracket 340 is provided above and beneath each one of the
pair of juxtaposed,
horizontally extending plurality of T profile protrusions 326. Outwardly open
