Description

DESCRIPTION

Monoblock box for shutters in window and door openings with manhole cover and safety lock.

Sector of the technique to which the invention refers

The present invention is applied to the thermal and acoustic insulation of shutter boxes installed in door and window closings of houses and buildings.

State of the prior art and object of the invention

Traditionally, the installation of the shutter box in the upper part of the opening of a door or window of a building poses the problem of closing and insulating the space where the roller shutter axis is housed. The simplest form of installation of the shutter is done by delimiting a work hole in the wall of the building where the axis, anchors and other fastening elements of the shutter are placed. Once this is installed, said opening or register is closed by means of a screwed or attached lid in different ways. The large empty space that this installation leaves inside the box, only protected by the closing cover of the register, produces a rapid loss of heat from the home and a transfer of the cold outside to the inside of it.

There are multiple solutions on the market to the problem that consist of placing boxes and plates of different materials in the window opening where the blind will be installed, which act as insulating elements, but its installation is either complex or requires of additional structural elements incorporated by the installer operator that slow down the process or make the product more expensive. The present invention is a box designed to be placed in the opening of the window frame and is formed by the union of various parts coupled and joined together that constitute a lightweight but resistant monoblock, which is hermetically closed and only open longitudinally by one end of its base coinciding with the exit of the blind, at the same time that it incorporates a manhole cover for placing the blind inside, as well as an additional system for closing and securing said cover.

Embodiment of the invention and description of the drawings

The box is formed by joining various pieces to form a compact, heat-insulating block that is very easy to install in the upper opening of windows or doors of buildings.

The box has two modes of implementation depending on its adaptation to the type of window that you want to install in the building and the location of the shutter exit opening.

Figure 1 shows a perspective side view of the first embodiment of the box with all its perimeter elements joined, except for the closing walls of its two end sides.

The general configuration of the box is tubular, with three pieces of expanded polystyrene (EPS), extruded (XPS) or any other material of low density and similar porosity of a certain thickness, joined perimetrically, leaving a longitudinal opening at the outer end of its base (1) coinciding with the shutter exit on the side furthest from the window frame.

One of these pieces, in the form of an inverted "L" (2), constitutes the upper and front or exterior sides of the box. The upper wall has an embedded and adhered plate (3) of polyvinyl chloride (PVC), which adds resistance and solidity to the box.The thickness of the end of the upper wall in correspondence with the interior of the house is reduced in relation to the rest of the body of the wall, delimiting a recess (4) or accommodation area of the upper edge of the manhole cover, said housing area has a centered longitudinal recess (5) in correspondence with the upper edge of the manhole cover.

The second of the pieces is generally rectangular in shape and constitutes the manhole cover (6), its lower edge projecting a longitudinal projection (7), and its upper edge a longitudinal recess (8) facing the recess in the previously accommodated area. described (5).

The third of the pieces has a general rectangular shape (9) with its upper face in a slightly descending plane for better positioning of the blind inside. of the box, and forms the basis of it. The upper face of the end corresponding to the house has a longitudinal cutout (10), where the projection of the cover (7) is attached. The outer longitudinal side is cut and facing the front lower longitudinal end of the box, at a certain distance, delimiting the exit opening of the window (1). The end of the lower face of the housing side of said piece has cutouts and longitudinal projections (11) that fit with the carpentry profile of the window frame. The edge of the part farthest from the window has a narrow longitudinal cut (12) in correspondence with the exit opening of the shutter and with the inner and bottom end of the front wall of the box, which has another cut. longitudinal (13), where two bars with brush are inserted to isolate the shutter exit opening. The interior of the central body of said base is reinforced with a polyvinyl chloride (PVC) plate (14) that runs longitudinally from side to side.

Figure 2 shows a perspective side view of the second embodiment of the box with all its perimeter elements joined, except for the closing walls of its two end sides.

The general configuration of the box is tubular, with three pieces of expanded polystyrene (EPS), extruded (XPS) or any other material of low density and similar porosity of a certain thickness, joined perimetrically, leaving a longitudinal opening at the outer end of its base coinciding with the shutter exit on the side closest to the window frame.

One of said pieces constitutes the upper, front or outer sides and most of the lower side of the box (15), its inner profile adopting a semicircular shape, to provide it with better insulation. The thickness of the end of the upper wall in correspondence with the interior of the house is reduced in relation to the rest of the body of the wall, delimiting a recess (16) or accommodation area of the upper edge of the manhole cover. Said housing area has a centered longitudinal cutout (17) in correspondence with the upper edge of the manhole cover.

The second of the pieces is generally rectangular in shape and constitutes the manhole cover (18), its lower edge projecting a longitudinal projection (19), and its edge a longitudinal recess (20) faces the recess of the previously described housing area (17).

The third of the pieces is shaped like a bar (21), is located under the manhole cover, extends from side to side of the box and has a longitudinal cutout (22), where the projection of the cover ( 19). The longitudinal side external to the housing of the bar is facing the end of the lower wall of the box, at a certain distance, delimiting the exit opening of the window (23). Said side of the bar and end of the lower wall have a narrow longitudinal cutout (24), where two bars with brush are inserted to isolate the outlet opening of the shutter.

Figure 3 shows a front view of the plate that each constitutes the side walls of the box.

This is a rectangular polyvinyl chloride (PVC) general configuration plate (25) that closes each of the furthest sides of the box. It has holes (26) where fixing screws are inserted on one side or the other depending on the side of the box where it is placed. A section of the underside of the plates closest to the house projects vertically (27) below the box to anchor it in the carpentry on the sides of the window frame.

Figure 4 shows a front and profile view of the manhole cover, as well as the box closing mechanism.

The cover has a generally rectangular shape (28) with its lower edge projecting a longitudinal projection (29), and its upper edge a longitudinal recess (30) facing the recess in the previously described housing area (5, 17).

The closing mechanism is formed by a generally rectangular polyvinyl chloride (PVC) upper bar (31), with its lower central part cut longitudinally describing an elongated irregular figure with two parallel inclined sides of different lengths in each of its ends (32) and an ascending semicircle in the center (33). The empty space delimited by said figure has an elongated lower bar (34) inserted with its most remote inclined sides (35) and in contact with the inclined sides of the upper bar. (32), the upper part of said bar experiencing a decrease with various longitudinally aligned recesses (36) where the teeth of a small toothed wheel (37) located in the empty space of the previously described semi-circumference whose center has a hole are inserted polygonal (38). The entire set of upper bar, lower bar and sprocket are inserted into the recess of the manhole cover (30), which has a hole (39) made in its upper part in correspondence with the sprocket hole that allows the insertion of an Allen key from the outside and turn the wheel that laterally displaces the lower bar, which pushes the upper bar and introduces it in the recess (5 and 17) of the upper wall of the box or reintroduces it in the cut-out (30) of the manhole cover, according to the direction of rotation of the key, by the pressure exerted by the inclined planes of the opposite and opposite sides (32 and 35) of the two bars.
