GLASS BODY GUARD ASSEMBLY SYSTEM THROUGH FITTED ALUMINUM PROFILES AND WEDGES

FIELD OF THE INVENTION [0001] This present application for a patent for a practical system of assembling glass railings through aluminum profiles composed of two interlocking parts and respective locks. The invention belongs to the civil construction segment, particularly in residential, commercial glass railings and sports facilities and infrastructure in general.

BACKGROUND OF THE INVENTION [0002] The depositor's practice of installing guardrails, through numerous works carried out, allowed to identify several problems of the current system, for being a single aluminum profile in "U" and count on countless parts that must be used according to each thickness of glass. Problems that this patent solves:

- Single U profile with expensive machining due to the difficulty of access at the bottom of the channel;

- Machining more expensive because it has to be conical;

- Difficulty in accessing the hole for placing and tightening the anchor bolt. Low productivity;

- Special non-standard tapered anchor on the market. High cost;

- As it is an Allen head tapered anchor, the tightening torque is reduced, requiring many anchor bolts per linear meter (10 anchor bolts per meter);

- A specific wedge for each thickness of glass used. Requiring high stock of parts;

- Single heavy profile for handling and installation;

11/11

- Profile already finished being susceptible to being damaged during the execution of the work;

- Complete absence of a level adjustment system.

STATE OF THE TECHNIQUE [0003] Currently, it is known and widely used in the market a single “U” shaped profile, extremely heavy (around 31 Kg the 5m bar) and difficult to install, as the anchor must be fixed at the bottom internal channel and access to the introduction and tightening is difficult, since this special anchor bolt with conical head and Allen, which offers little tightening torque and damages the elongated tightening tips in automatic screwdrivers too much. The screwdriver can also damage the profile when the mandrel hits the top of the profile when the tip is reduced to continue its use. Access to the screw introduction is also hampered by the depth of the channel. As it is a tapered anchor bolt with Allen head, the tightening torque is reduced, requiring many anchor bolts per linear meter (10 anchor bolts per meter).

[0004] In the state of the art, the system also does not have any level adjustment, which makes the task of placing the entire installation aligned and level. The glasses that will be fitted in the configured channel are perfect rectangles, with few clearances, which do not allow adjustments out of level and plumb.

[0005] Another aspect to be considered in the state of the art is that the profile is already finished and, at the time of fixing it to the work, it is still in a very rough state, which causes scratches and stains of all kinds, compromising the presentation of the final product when the finished work.

[0006] On the other hand, machining is also difficult in the current profile, as a conical and through hole must be drilled inside and at the bottom of the channel, which makes the process and the final product more expensive, as can be seen in Figures 1 and 2.

3/11 [0007] A wedge of plastic material is used to lock the glass and it must be of varying size and specific to each thickness of glass used. Demanding high control and stock of parts both in the factory and on site.

[0008] In terms of patent reference documents, reference can be made to the

BR102016020298-1, deposited on 9/1/2016 and published on 3/14/2017, which describes a set of pieces developed in cut and folded sheets in the shape of an octagonal upright profile, consisting of a lower fixing flange with holes for fixing in masonry base, front mirror constructed from a straight central profile whose side flaps form oblique closing angles forwards, and extend on smaller flaps at right angles to the front; then they curve into straight closures, ending in guide wings curved at a right angle to the front, chaplets and fixing nuts distributed along the guide wings, top cover and rear mirror built from a straight central profile whose side flaps form oblique angles closing forward and extend into smaller flaps at right angles forward, curved into straight closing, ending in a free span to couple the guide flaps of the front mirror forming the left and right side recesses, allowing to accommodate leaves of glass, the whole set is fixed by the fixing screws that cross the holes on the rear mirror by screwing the fixing nuts.

[0009] The document BR202016002402-7 describes an improvement introduced in a set of accessories and profiles for the guardrail system, with waiting for balcony glazing, being the same compound, respectively, by: column, position of fixation of the rods; regulation plate; superior finish; bottom finish; handrail cover; and handrail; form the referred support / guardrail system (with double pin fixation), so that they act simultaneously, with their respective functions, providing greater ease of installation, considering the plate

[0010] The document BR112013025978-7, deposited on 10/04/2012 and published on 12/20/2016, referring to BODYWORK, describes a bodyguard that serves to protect people who are present on open floors of buildings or scaffolding against the accidental fall due to the opening of the mentioned floors. The railing comprises several construction elements and connectors for mounting said construction elements to a coherent railing. The connectors comprise at least one first connector that has a longitudinal shape and is formed with at least one longitudinally extending slit and at least a second connector consisting of a first connector part to be connected to at least one building element and a second connector part for connecting the first connector part to at least one first connector while engaging the at least one longitudinally extending slit thereof. The railing of the invention has a simple structure that is both stable and inexpensive, which can be quickly and easily assembled into a coherent body and disassembled again. The guardrail can also, in addition, be adapted to the required width and height of the guardrail for a specific opening of a given open floor.

[0011] The document MU8401447-4 SECURITY FIXING COLUMN FOR GUARDING BODY BALCONY AND GRILLS IN GENERAL, deposited on 07/08/2004 and published on 02/21/2006, refers to a set formed by a pin stainless steel in cylinder shape, a longitudinal plate folded in a 'U' shape, both folds with specific angulation, composing two square plates with central drilling and two-component polymer catalyzed with exothermic reaction, whose purpose is to provide security for fixation of grids in general and railings of balconies, with its field of application directed to civil construction. The fixing column presents an unprecedented constructive innovation and easy handling, fixing itself to the

5/11 soil by means of the steel pin anchor, the rest of the body of the fixing column is exposed to receive the railings of balconies and railing profiles in general.

[0012] The state of the art documents usually reflect devices that have the usual characteristics with regard to the installation of anchor bolts, as described above.

[0013] Still, in the system currently in use, there is a need for a large number of holes in the concrete base, for example, one every 10 cm, generating expressive manpower. However, there is a need for a long Allen key to be brought into the profile.

GENERAL DESCRIPTION OF THE INVENTION [0014] The present invention contemplates two separate profiles that are used in two specific moments of the installation and according to the phases of the work. The lower profile of only 5Kg in a 5m bar is used to fix the building and level the system. It has hexagonal head bolts that allow greater torque and easy access for fixing with standard market sockets and screwdriver working free and loose. Machining this profile is also simple with only through holes.

[0015] This lower profile can be used at the stage when the work is even more rough, because if it is stained or damaged, it does not compromise the final result because it will be covered by the posterior fitting profile.

[0016] The nut and counter nut system facilitates leveling and reduces installation time and increases the precision and finish of the work.

[0017] The second profile arrives with the entire system leveled and comes as a finish in a phase of the cleaner work that already allows the installation of glass. The system is fitted so that it can only be removed with the downward movement inward, which is locked by the safety wedges, which

Petition 870180021026, of 03/15/2018, p. 9/27

6/11 are pressed into the drawers which ensures that the entire set now functions as one.

[0018] The anchor bolt in the molds of the system of the invention can be inserted at greater distances from each other (for example, 25 cm), with the lower profile performing all the work of positioning and leveling, the upper profile being inserted at a later stage, without suffering aggressions that could harm you.

[0019] The plastic wedge becomes a single piece with a slit to highlight the double functionality and practicality for using glasses in different thicknesses.

OBJECTIVES OF THE INVENTION [0020] The objective of the invention is a system developed from the assembly in two stages, one fixing the lightest profile from the bottom in a simple and practical way, using hexagon head screws that facilitates access and maximizes the torque in relation to current systems, minimizing the need for holes per meter and reducing to 25% of the current total which use screws in addition to a tapered head at the bottom of the channel, which also makes access and the possibility of tool breakage and damage to the profile difficult.

[0021] Another objective of the invention is to facilitate and decrease the installation time of the aluminum profile in glass railings; as well as reducing the risk of damage to the finished profile in the installation process and due to the construction phase, which is still very rough.

[0022] It also aims to reduce the cost of the profile from simpler machining, while the final weight of the sum of the aluminum profiles is practically kept close to the traditional one.

[0023] It also aims to allow easy level adjustment through the nut and counter nut system; in addition to increasing the tightening torque of the anchor bolts, ensuring better and more efficient fastening.

Petition 870180021026, of 03/15/2018, p. 10/27

7/11 [0024] another objective is to reduce the total cost of the system, from machining, to the standard hexagonal anchor bolt, due to the need for fewer holes and anchor bolts and reduced general installation time saving labor.

DETAILED DESCRIPTION OF THE INVENTION [0026] THE SYSTEM OF ASSEMBLY OF GLASS BODY THROUGH ALUMINUM PROFILE, object of this patent application, aims to replace a conventional aluminum profile (1), composed of a base or bottom (2) with hole (3) with conical head (4), where the fixing and anchoring element (4B) is fixed (Figure 8) and wedge with specific dimension for each thickness (E) of glass. This unique “U” -shaped profile (1) is heavy (31Kg to 5m bar), having difficult installation, since the anchor bolt must be fixed to the internal bottom (2) of the channel, with access to the introduction and tightening it is difficult; as it is the head of the tapered anchor, it gives little tightening torque and ends up damaging the elongated tightening tips in automatic screwdrivers. However, the screwdriver can also damage the profile (1) when the mandrel hits the top of said profile (1), particularly when the tip is reduced to continue its use. Another characteristic indicating difficulty lies in the fact that access to the screw introduction is also hampered by the depth of the channel, requiring the introduction of an Allen key inside the profile.

[0027] Another characteristic of the traditional profile (1) is the fact that the system does not have any level adjustment, which makes the task of placing the entire installation aligned and level. The glasses to be fitted in the channel are perfect rectangles with few clearances and that do not allow adjustments of out of level and plumb.

[0028] The profile (1) of the state of the art has already been completed and, at the time of fixing it to the work, it is in a very rough state, which causes scratches and stains of all kinds, compromising the presentation of the final product.

[0029] Problems are also reported with regard to extremely difficult machining in the profile (1) of the state of the art, as it requires the opening of a through tapered hole inside and at the bottom of the channel (2), which makes the process more expensive and the final product.

Petition 870180021026, of 03/15/2018, p. 12/27

9/11 [0030] In the system of the present invention two separate profiles (5) and (6) are used and used in two specific moments of the installation, the first profile (6) being used for fixation in the building (E) and leveling of the system; the second profile (5) arrives with the entire system leveled and comes as a finish in a cleaner phase of the work that already allows the installation of the glasses.

[0031] The profile (5), or higher, is in "U" configuring at the bottom a transverse wall (7) that immediately defines an open area (8) with internal (9) and external (10) coupling. Laterally, the profile (5) has, immediately above the coupling of the profile (6), a recess (5B) to house a security lock (5C).

[0032] The profile (6), or lower, has a format compatible with the open area (8) of the profile (5), with couplings (11) and (12) cooperating with the couplings (9) and (10), of so that, when the profile (2) is inserted in the open area (8), an almost symmetrical relationship of indentations (13) establishes a hollow area (8B) where the hex head (14) of a screw (15) that moves through the profile (6) on whose outer surface is a recessed base (16) for actuation or not of a leveling counter nut (17).

[0033] Thus, the profile (6) with only 5Kg in a 5m bar, is used to fix the building (masonry) and level the system. As described above, the profile (6) receives hexagon head bolts, standing out for its easy access for fixing, using standard market sockets and screwdriver working free and loose.

[0034] Profile (6) can be used at the stage when the work is even more rough, because if it is stained or damaged in any way, it does not compromise the final result.

[0035] The nut and counter nut system, on the other hand, facilitates leveling and reduces installation time, in addition to increasing accuracy and greatly improving the workmanship.

Petition 870180021026, of 03/15/2018, p. 13/27

10/11 [0036] The profile (5) is already applied with the entire system leveled and comes as a finish in a cleaner phase of the work that already allows the installation of the glasses. The system is fitted and locked by means of safety wedges inserted in the drawers (18), ensuring that the whole set works as a single unit.

[0037] For the operation of assembling a 12mm glass, according to an embodiment shown in Figure 1, the profile (5) receives, on one side, an internal “L” wedge (5D) that forms a base support for the glasses (V), this wedge (5D) having a sectioning (5E) that configures a point of contact and weakening that can, eventually, be used to break the said internal wedge (5D) generating to the other internal face from the profile (5) another wedge (5F) that is used to lock the glass, which according to the thickness of the glass (V) it can be used double one up and one inverted as shown (5G).

[0038] Figure 3 shows the use of the system for, for example, in one embodiment, for 16mm (V) glasses, using the same wedge mechanism (5D) (5G), (5F), sectioning (5E ) and locking wedges (5F) (5G), these in a smaller or greater distance due to the greater thickness of the glass (V).

[0039] Figure 5 shows the use of the system, for example, in an embodiment, for 20mm glasses (V), where the wedges (5D), (5F) are kept, as well as the sectioning (5E), eliminating the need for inverted wedges (5G); the left is the version with counter nut and the right is the version without counter nut.

[0040] Figure 7 illustrates the assembly of the guardrail according to the invention, from movement (M0) to movement (M5), where, in a version without counter leveling nut (17), the profile (6) is initially fixed and flush with the masonry structure (E); once this is done, the profile (5) is sequentially attached to the profile (6), as described, until, when complete, the safety lock (5C)
