In one embodiment there is an apparatus for restraining fiber optic cables.
The apparatus may comprise a unit for restraining fiber optic cables. The unit may include a base plate and a frame extending outwardly from said base plate, and the frame may have an external contour retracted from a periphery of said base plate. The apparatus may further comprise a plurality of first hollow semi-cylinders spaced apart from a plurality of second hollow semi-cylinders to define a plurality of completed hollow cylinders extending outwardly from the base plate. The cylinders may be disposed in horizontal and vertical rows. Each said first hollow semi-cylinder may have a first inclined upper surface resulting from an intersection with a first imaginary inclined plane emerging from an interior of said first hollow semi-cylinder and directed upwardly from said base plate. Each said second hollow semi-cylinder may have a second inclined upper surface resulting from an intersection with a second imaginary inclined plane emerging from an exterior of said second hollow semi-cylinder and directed upwardly from said base plate. Each said first hollow semi-cylinder and said second hollow semi-cylinder may extend outwardly from said base plate, with each second hollow semi-cylinder extending outwardly above each said first hollow semi-cylinder. Each said second hollow semi-cylinder may have an internal radius shorter than an internal radius of each said first hollow semi-cylinder. Each pair of said first hollow semi-cylinders may have their ends contiguously joined to define a central portion. An opposite pair of said second hollow semi-cylinder may be interconnected by a horizontal brace contiguously joined with said central portion of each pair of said first hollow semi-cylinders. The apparatus may further comprise a plurality of tubular elements, each tubular element being contiguously joined with the central portion of each pair of said first hollow semi-cylinders and including a blind hole exteriorly located with respect to each pair of said first hollow semi-cylinders. An inclined upper surface of each of said tubular elements may be coplanar with said first inclined upper surface of each said first hollow semi-cylinder. The apparatus may further comprise a restraining bracket including a row comprising a plurality of semi-cylinders. Each said semi-cylinder may comprise an internal radius that is approximate to the internal radius of each said second hollow semi-cylinder, complementary to each said second hollow semi-cylinder, and includes an interior surface with anti-slip striations. The restraining bracket may include a plurality of through holes and an inclined lower surface with
3 an inclination approximate to an inclination of the first inclined upper surface of each said first hollow semi-cylinder. Each said through hole of the plurality of through holes may coincide with one of said blind holes of said plurality of tubular elements when said inclined lower surface of said restraining bracket is placed against said first inclined upper surface of said first hollow semi-cylinder. Each said blind hole may be engageable with an attachment element extending through each said through hole to advance said restraining bracket towards said unit for restraining fiber optic cables in order to restrain one or more fiber optic cable(s) between said first hollow semi-cylinders and said second hollow semi-cylinders.
3a Broadly stating, the inventors, after substantial experimentation and testing, have devised a unit for restraining fiber optic cables including a base plate and a frame slightly extending outwards from a top of the base plate and having its external contour, equally retracted from a periphery of the base plate. A plurality of first hollow semi-cylinders is correspondingly completed by a plurality of second hollow semi-cylinders, the resulting, completed hollow cylinders being disposed in horizontal and vertical rows, circumvented at their bottom by the frame, after they start from a bottom of the base plate. Each first hollow semi-cylinder has a curved, inclined upper surface, part of an ellipse, resulted from an intersection with an imaginary, inclined plane emerging from an interior of the first hollow semi-cylinder and directed upwardly.
Each second hollow semi-cylinder has a curved, inclined upper surface, part of an ellipse, resulted from a intersection with an imaginary, inclined plane emerging from an exterior of the second hollow semi-cylinder and directed upwardly. Each second semi-cylinder projects outwardly above each first hollow semi-cylinder. Each second hollow semi-cylinder has a slightly shorter internal radius than that of each first hollow semi-cylinder.
Each pair of first hollow semi-cylinders has their ends contiguously joined. An opposite pair of second hollow semi-cylinder is interconnected by a horizontal brace and to which the ends of each pair of first hollow semi-cylinders also adhere. A relatively small tubular element, provided with a blind hole, is exteriorly located with respect to each pair of first hollow semi-cylinders.
Thus, several relatively small tubular elements are formed, so that each one constitutes an outside, contiguous extension of each pair of first hollow semi-cylinders. A
forward surface of each of relatively small tubular element is coplanar with the inclined upper surface of each first hollow semi-cylinder. A restraining bracket includes a row incorporating a plurality of semi-cylinders, numerically equal to a plurality of first hollow semi-cylinders, or second hollow semi-cylinders.

Each second hollow semi-cylinder has a curved, inclined upper surface, part of an ellipse, resulted from a intersection with an imaginary, inclined plane emerging from an exterior of the second hollow semi-cylinder and directed upwardly. Each second semi-cylinder projects outwardly above each first hollow semi-cylinder. Each second hollow semi-cylinder has a slightly shorter internal radius than that of each first hollow semi-cylinder.
Each pair of first hollow semi-cylinders has their ends contiguously joined. An opposite pair of second hollow semi-cylinder is interconnected by a horizontal brace and to which the ends of each pair of first hollow semi-cylinders also adhere. A relatively small tubular element, provided with a blind hole, is exteriorly located with respect to each pair of first hollow semi-cylinders.
Thus, several relatively small tubular elements are formed, so that each one constitutes an outside, contiguous extension of each pair of first hollow semi-cylinders. A
forward surface of each of relatively small tubular element is coplanar with the inclined upper surface of each first hollow semi-cylinder. A restraining bracket includes a row incorporating a plurality of semi-cylinders, numerically equal to a plurality of first hollow semi-cylinders, or second hollow semi-cylinders. The row comprises a plurality of semi-cylinders, each semi-cylinder being defined by a
4 semicircular ring sector and by an internal radius, the latter being equal to that of each second hollow semi-cylinder. Each one of plurality of half cylinders is complementary to each second hollow semi-cylinder. A series of parallel, semicircular anti-slip striations covering an interior of each one of plurality of half cylinders, the restraining bracket being provided with several through holes coinciding with the relatively small tubular elements, respectively with their blind holes, which are equally spaced and enlarging toward their exit. The elongated, restraining bracket has a bottom, beveled, partial zone extending along a length of said elongated, restraining bracket; the bottom, beveled, partial zone having an inclination shared by each first hollow semi-cylinder and top surface of each elongated through hole. By tightening screws, via the elongated through holes, into relatively small tubular elements, an inwards advancement of the elongated, restraining bracket takes place, thus, one or more fiber optic cable(s) is (are) tensively restrained into the unit for restraining fiber optic cables and, when necessary, more restraining brackets could be used, in parallel, as separate entities, or can be laterally and consecutively interconnected.
In one aspect of the present invention, the unit for restraining fiber optic cables is combined with an enclosure attaching unit, used to connect the unit for restraining fiber optic cables to a fiber optic enclosure. The enclosure attaching unit comprises a front, positioning frame extending backwardly and perpendicularly into a trilateral, open frame.
The latter is provided with a trilateral continuous channel, inwardly open and so dimensioned as to allow the unit for restraining fiber optic cables, namely a margin of the base plate, situated between a periphery of the latter and the rectangular frame, to be inserted in a close-fitting manner, by translation, into said trilateral continuous channel.
The trilateral, open frame extends outwards into an elongated closing bracket provided with rounded ends. The elongated closing bracket has a vertical wall provided at its upper margin with a brim perpendicularly extending from the vertical wall. A top surface of the brim, respectively of the vertical wall, being so located as to be coplanar with a bottom surface of the unit for restraining fiber optic cables, when the latter is installed into enclosure attaching unit. A relatively small cut being backwardly open and located at the middle of the top surface of the brim; a relatively small, narrow cut is provided in the vertical wall, positioned under the relatively small cut. The wedge shape protrusion is intended to preclude an inadvertent movement of the unit for restraining fiber optic cables, by immobilizing the latter into a working position. By actuating downwards, via the relatively small, narrow cut, the elongated closing bracket is preempted to block the restraining unit for restraining fiber optic cables, with the wedge shape protrusion, to be forwardly translated, hence dismounted. The front, positioning frame, starting from its bottom extends backwardly into a flat zone expanding into a curved zone, followed by trilateral, open frame provided backwardly with front and back flanges.
Between the former and latter, except an upper part, a relatively large channel, retracted from a periphery of front and back flanges, being formed; the relatively large channel being sized and shaped to be easily nested into a corresponding aperture of the fiber optic enclosure. Between the front and back flanges, at their upper part, in both sides and extending above the relatively large channel, a pair of guiding channels for lodging a segment of a continuous peripheral seal of said fiber optic enclosure is provided.
The back flange extends backwards into a perpendicular, flat, cantilever base provided with openings for attachment. A pair of elongated elements, located perpendicularly at the extremities of the cantilever base is each provided with a recessed hole used to attach a complimentary open-close cover. The latter has a flat top, flanked perpendicularly by a pair of lateral walls. The flat top and the pair of lateral walls extend backwardly into a rounded part that ultimately ends into a flat sector. An intermediary channel, protruding out of the flat sector is collinearly interposed between the pair of guiding channels and intended for the same purpose. A pair of pierced ears projects perpendicularly from the front flange and is so located as to coincide with the pair of elongated elements, when the complementary open-close cover is flipped in a closed position. The complementary open-close cover is so profiled as to fit snugly over and around the front, positioning frame and partially over the flat and curved zones. The complementary open-close cover is intended for interconnecting the former and the latter, thus allowing the latter to open for inserting the unit for restraining fiber optic cables and to close it after the inserting is done.
In another aspect, the unit for restraining fiber optic cables combinable with attaching units, as defined in claim 1, further including a wall mountable attaching unit intended for connecting the unit for restraining fiber optic cables to a wall; said wall mountable attaching unit is comprised of a rectangular, vertical base plate provided proximately to its upper and lower margins, with a pair of inverted keyhole apertures. A
mounting, cantilever frame projects perpendicularly out of the vertical base plate and has a U-shape, is forwardly open and extends internally into an inwards open channel. The vertical base plate extends frontwards into an elongated closing bracket and is provided with rounded ends. The elongated closing bracket has a vertical wall provided at its upper margin with a brim perpendicularly extending from the latter. A top surface of the brim, respectively of the vertical wall is so disposed as to be coplanar with a bottom surface of the unit for restraining fiber optic cables combinable with attaching units (when the latter is installed into the wall mountable attaching unit). A bottom surface of the elongated closing bracket is coplanar with a bottom of the mounting, cantilever frame. A relatively small cut, backwardly open is located at the middle of the top surface of the brim. A
relatively small, narrow cut is provided in the vertical wall is positioned under the relatively small cut. The wedge shape protrusion is intended to preempt an inadvertent movement of the unit for restraining fiber optic cables, by immobilizing the latter in a working position. By actuating downwards, via the relatively small, narrow cut, elongated closing bracket is preempted to block the unit for restraining fiber optic cables together with the wedge shape protrusion, to be forwardly translated, hence dismounted.

IV. DESCRIPTION OF THE PREFERRED EMBODIMENTS
The accompanying drawings, as above described, depict preferred embodiments of a unit for restraining fiber optical cables, combinable with attaching units. That embodiment is intended for terrestrial networks. Reference number 10 was chosen for generally naming a unit for restraining fiber optical cables 100 combined with an enclosure attaching unit 200 or with a wall mountable attaching unit 300. For simplification, throughout the present specification, use will be made of the wording "unit for restraining 100" instead of "unit for restraining fiber optical cables 100".
Unit for restraining 100 comprises a base plate 102 of rectangular shape, so disposed that its horizontal axis of symmetry is relatively larger than its vertical axis of symmetry. A
rectangular frame 104 extends from a top of base plate 102 and its external contour is equally retracted from the periphery of the latter. Six first hollow semi-cylinders 106 are correspondingly completed by six second hollow semi- cylinders 108. The resulted, completed hollow cylinders are disposed in six horizontal and four vertical rows, which are together circumvented by rectangular frame 104, after they start from bottom of base plate 102.
Each first hollow semi-cylinder 106 has a curved, inclined upper surface 106', part of an ellipse, resulted from an intersection with an imaginary, inclined plane emerging from an interior of first hollow semi-cylinder 106 and directed upwardly.
Each second hollow semi-cylinder 108 has a curved, inclined upper surface108', part of an ellipse, resulted from an intersection with an imaginary, inclined plane emerging from an exterior of second hollow semi-cylinder 108 and directed upwardly.
Each second hollow semi-cylinder 108 projects outwardly beyond /rises above/
each first hollow semi-cylinder 106 and each second hollow semi-cylinder 108 has a slightly shorter internal radius than that of each first hollow semi-cylinder 106. Each pair of consecutive first hollow semi-cylinders 106 have their ends contiguously joined together;
an opposite pair of consecutive second hollow semi-cylinder 108 are interconnected by a horizontal brace 110 to which the ends of each pair of consecutive first hollow semi-cylinders 106 also adhere.
A relatively small tubular element 112, provided with a blind hole, is exteriorly located with respect to each pair of first hollow semi-cylinders 106. Thus, several relatively small tubular elements 112 are formed, each one constituting an outside, contiguous extension of each pair of first hollow semi-cylinders 106. A forward surface 114 of each relatively small tubular element 112 has the same inclination, i.e. is coplanar with the inclined upper surface of each first hollow semi-cylinder 106. A wedge shaptkiprotrusion 116 is located on the bottom of the base plate 102. The use of the former will be disclosed further in the present specification.
A restraining bracket 150, which is horizontally extending, includes a row with the same number as first hollow semi-cylinders 106, or second hollow semi-cylinders 108. The row comprises six semi-cylinders 152, each defined by a semicircular ring sector and by an internal radius, equal to that of each second hollow semi-cylinder 108. Each one of the several half cylinders 152 is complementary to each second hollow semi-cylinder 108. A
series of parallel, semicircular anti-slip striations 154 covers an interior of each of the several half cylinders 152. Restraining bracket 150 is provided with several through holes 156 that coincide with relatively small tubular elements 112, with their blind holes, respectively.
Several elongated, through holes 156 have their top surfaces inclined, are equally spaced and enlarge toward their exit; they are located in areas wherein two consecutive semi-holes are joined by a brace 158 that mates a horizontal brace 110. Elongated, restraining bracket 150 has a bottom, beveled partial zone 160 extending along a length of the former.
The latter has an inclination shared by each first hollow semi-cylinder 106 and the top surface of each elongated through hole 156. By tightening screws S throughout elongated through holes 156 into relatively small tubular elements 112, an inwards advancement of elongated, restraining bracket 150 takes place. Thus, one or more fiber optic cable(s) is (are) tensively restrained into unit for restraining 100. When necessary, more restraining brackets 150 could be used, in parallel, as separate entities, or can be laterally and consecutively interconnected.
Enclosure attaching unit 200, used to connect unit for restraining 100 to a fiber optic enclosure FE, resembles, in general, a rectangular head lamp for cars.
Enclosure attaching unit 200 is comprised of a front, positioning frame 205 which extends backwardly and perpendicularly into a trilateral, open frame 210. The latter is provided with a trilateral continuous channel 215, inwardly open and so dimensioned as to allow unit for restraining 100, namely a margin of base plate 102, situated between a periphery of the latter and rectangular frame 104, to be inserted in a close-fitting manner, by translation, into trilateral continuous channel 215. Trilateral, open frame 210 extends outwards into an elongated closing bracket CB provided with rounded ends RE. Elongated closing bracket CB
has a vertical wall VW provided at its upper margin with a brim BR perpendicularly extending from the latter. Top surface TS of brim BR, respectivelY of vertical wall VW, is so located as to be coplanar with a bottom surface BS of unit for restraining 100 /when the latter is installed into enclosure attaching unit 200. A relatively small cut SG is backwardly open and located at the middle of top surface TS of brim BR. A relatively small, narrow cut SC
is provided in vertical wall VW, positioned under relatively small cut SC.
Wedge shapek protrusion 116, described before, is intended to preclude an inadvertent movement of restraining unit 100, by immobilizing the latter in the working position. By actuating downwards, via relatively small, narrow cut SC, elongated closing bracket 340 is preempted to block restraining unit 100 with its wedge. shaped protrusion 116, to be forwardly translated, hence dismounted. Front, positioning frame 205, starting from its bottom extends backwardly into a flat zone 220, which expands into a curved zone 225.
The latter extends into trilateral, open frame 210 which is provided backwardly with front and back flanges, respectively 230 and 235. Between the former and latter, except an upper part, a relatively large channel 240, retracted from the periphery of front and back flanges, respectively 230 and 235, is formed. Relatively large channel 240 is sized and shaped to be easily nested into a corresponding aperture of a fiber optic enclosure FE.
Between front and back flanges, respectively 230 and 235, at their upper part, in both sides and extending above relatively large channel 240, there is a pair of guiding channels 245 for lodging a segment of a continuous peripheral seal (not shown) of fiber optic enclosure FE.

IV. DESCRIPTION OF THE PREFERRED EMBODIMENTS
The accompanying drawings, as above described, depict preferred embodiments of a unit for restraining fiber optical cables, combinable with attaching units. That embodiment is intended for terrestrial networks. Reference number 10 was chosen for generally naming a unit for restraining fiber optical cables 100 combined with an enclosure attaching unit 200 or with a wall mountable attaching unit 300. For simplification, throughout the present specification, use will be made of the wording "unit for restraining 100" instead of "unit for restraining fiber optical cables 100".
Unit for restraining 100 comprises a base plate 102 of rectangular shape, so disposed that its horizontal axis of symmetry is relatively larger than its vertical axis of symmetry. A
rectangular frame 104 extends from a top of base plate 102 and its external contour is equally retracted from the periphery of the latter. Six first hollow semi-cylinders 106 are correspondingly completed by six second hollow semi- cylinders 108. The resulted, completed hollow cylinders are disposed in six horizontal and four vertical rows, which are together circumvented by rectangular frame 104, after they start from bottom of base plate 102.
Each first hollow semi-cylinder 106 has a curved, inclined upper surface 106', part of an ellipse, resulted from an intersection with an imaginary, inclined plane emerging from an interior of first hollow semi-cylinder 106 and directed upwardly.
Each second hollow semi-cylinder 108 has a curved, inclined upper surface108', part of an ellipse, resulted from an intersection with an imaginary, inclined plane emerging from an exterior of second hollow semi-cylinder 108 and directed upwardly.
Each second hollow semi-cylinder 108 projects outwardly beyond /rises above/
each first hollow semi-cylinder 106 and each second hollow semi-cylinder 108 has a slightly shorter internal radius than that of each first hollow semi-cylinder 106. Each pair of consecutive first hollow semi-cylinders 106 have their ends contiguously joined together;
an opposite pair of consecutive second hollow semi-cylinder 108 are interconnected by a horizontal brace 110 to which the ends of each pair of consecutive first hollow semi-cylinders 106 also adhere.
A relatively small tubular element 112, provided with a blind hole, is exteriorly located with respect to each pair of first hollow semi-cylinders 106. Thus, several relatively small tubular elements 112 are formed, each one constituting an outside, contiguous extension of each pair of first hollow semi-cylinders 106. A forward surface 114 of each relatively small tubular element 112 has the same inclination, i.e. is coplanar with the inclined upper surface of each first hollow semi-cylinder 106. A wedge shaptkiprotrusion 116 is located on the bottom of the base plate 102. The use of the former will be disclosed further in the present specification.
A restraining bracket 150, which is horizontally extending, includes a row with the same number as first hollow semi-cylinders 106, or second hollow semi-cylinders 108. The row comprises six semi-cylinders 152, each defined by a semicircular ring sector and by an internal radius, equal to that of each second hollow semi-cylinder 108. Each one of the several half cylinders 152 is complementary to each second hollow semi-cylinder 108. A
series of parallel, semicircular anti-slip striations 154 covers an interior of each of the several half cylinders 152. Restraining bracket 150 is provided with several through holes 156 that coincide with relatively small tubular elements 112, with their blind holes, respectively.
Several elongated, through holes 156 have their top surfaces inclined, are equally spaced and enlarge toward their exit; they are located in areas wherein two consecutive semi-holes are joined by a brace 158 that mates a horizontal brace 110. Elongated, restraining bracket 150 has a bottom, beveled partial zone 160 extending along a length of the former.
The latter has an inclination shared by each first hollow semi-cylinder 106 and the top surface of each elongated through hole 156. By tightening screws S throughout elongated through holes 156 into relatively small tubular elements 112, an inwards advancement of elongated, restraining bracket 150 takes place. Thus, one or more fiber optic cable(s) is (are) tensively restrained into unit for restraining 100. When necessary, more restraining brackets 150 could be used, in parallel, as separate entities, or can be laterally and consecutively interconnected.
Enclosure attaching unit 200, used to connect unit for restraining 100 to a fiber optic enclosure FE, resembles, in general, a rectangular head lamp for cars.
Enclosure attaching unit 200 is comprised of a front, positioning frame 205 which extends backwardly and perpendicularly into a trilateral, open frame 210. The latter is provided with a trilateral continuous channel 215, inwardly open and so dimensioned as to allow unit for restraining 100, namely a margin of base plate 102, situated between a periphery of the latter and rectangular frame 104, to be inserted in a close-fitting manner, by translation, into trilateral continuous channel 215. Trilateral, open frame 210 extends outwards into an elongated closing bracket CB provided with rounded ends RE. Elongated closing bracket CB
has a vertical wall VW provided at its upper margin with a brim BR perpendicularly extending from the latter. Top surface TS of brim BR, respectivelY of vertical wall VW, is so located as to be coplanar with a bottom surface BS of unit for restraining 100 /when the latter is installed into enclosure attaching unit 200. A relatively small cut SG is backwardly open and located at the middle of top surface TS of brim BR. A relatively small, narrow cut SC
is provided in vertical wall VW, positioned under relatively small cut SC.
Wedge shapek protrusion 116, described before, is intended to preclude an inadvertent movement of restraining unit 100, by immobilizing the latter in the working position. By actuating downwards, via relatively small, narrow cut SC, elongated closing bracket 340 is preempted to block restraining unit 100 with its wedge. shaped protrusion 116, to be forwardly translated, hence dismounted. Front, positioning frame 205, starting from its bottom extends backwardly into a flat zone 220, which expands into a curved zone 225.
The latter extends into trilateral, open frame 210 which is provided backwardly with front and back flanges, respectively 230 and 235. Between the former and latter, except an upper part, a relatively large channel 240, retracted from the periphery of front and back flanges, respectively 230 and 235, is formed. Relatively large channel 240 is sized and shaped to be easily nested into a corresponding aperture of a fiber optic enclosure FE.
Between front and back flanges, respectively 230 and 235, at their upper part, in both sides and extending above relatively large channel 240, there is a pair of guiding channels 245 for lodging a segment of a continuous peripheral seal (not shown) of fiber optic enclosure FE. Back flange 235 extends backwards into a perpendicular, flat, cantilever base 250, provided with openings for attachment 255. A pair of elongated elements 260, located perpendicularly at the extremities of cantilever base 250 is each provided with a recessed hole (not shown). The former is used to attach complimentary open-close cover 265, further disclosed.
Enclosure attaching unit 200 is further comprised of a complementary open-close cover 265, resembling, in general, a trunk lid of a car. Complementary open-close cover 265 has a flat top 270 which is flanked perpendicularly by a pair of lateral walls 275; flat top 270 and the pair of lateral walls 275 extend backwardly into a rounded part 280 that ultimately ends with a flat sector 285. An intermediary channel 290, protruding out of flat sector 285, is collinearly interposed between the pair of guiding channels 245 and intended for the same purpose. A pair of pierced ears 295 projects perpendicularly from front flange 230 and is so located as to coincide with the pair of elongated elements 260, when complementary open-close cover 265 is flipped in a closed position.
Complementary open-close cover 265 is so profiled as to fit snugly over and around front, positioning frame 205 and partially over flat and curved zones 220 and 225. A pair of hinges 298, situated at top of front, positioning frame 205 and top of complementary open-close cover 265, interconnects the former and the latter, thus allowing the latter to open for inserting the unit for restraining 100 and to close after the inserting is done.
Wall mountable attaching unit 300, intended for connecting unit for restraining 100 to a wall W, is comprised of a rectangular, vertical base plate 305 provided proximate to its upper and lower margins, with a pair of inverted keyhole apertures 310. Each inverted keyhole aperture 310 has a narrow, rectangular opening 315 ending upwards in a rounded segment 320 and extending downwards in a circular zone 325. A mounting, cantilever frame 330 projects perpendicularly out of vertical base plate 305, has a U-shape, is forwardly open and extends internally into an inwards open channel 335. The former extends frontwards into an elongated closing bracket 340 provided with rounded ends 345. Elongated closing bracket 340 has a vertical wall 350 provided at its upper margin with a brim 355 perpendicularly extending from the latter. Top surface 360 of brim 355, respectively of vertical wall 350, is so disposed as to be coplanar with a bottom surface BS
of unit for restraining 100 (when the latter is installed into wall mountable attaching unit 300); a bottom surface 365 of elongated closing bracket 340 is coplanar with the bottom of mounting, cantilever frame 330. A relatively small cut 370, backwardly open is located at the middle of top surface 360 of brim 355; a relatively small, narrow cut 375 is provided in vertical wall 350, positioned under relatively small cut 370. Wedge shaped protrusion 116, described before, is intended to preempt an inadvertent movement of restraining unit 100, by immobilizing the latter in the working position. By actuating downwards via relatively small, narrow cut 375, elongated closing bracket 340 is preempted to block restraining unit 100 with its wedged-shaped protrusion 116, to be forwardly translated, hence dismounted.
