DESCRIPTION

IMPROVEMENT IN DRAWER FOR DOORS AND ROLLERS

5

SECTOR OF THE TECHNIQUE

The present invention relates to an improvement in the drawers where

They house blinds and roller doors. The proposed improvement consists of

10 provide it with insulating elements, which reduce the thermal transmission coefficient of the drawer, from outside the premises where they are installed inwards, and vice versa; furthermore, said elements reduce air permeability, increase the

water tightness and wind load resistance.

15 BACKGROUND OF THE INVENTION

There are plenty of drawers for doors and roller shutters, formed by some

side doors and covers that are attached to the heads, by various methods. The

The purpose of these drawers is to collect the blind or door when it is rolled up, leaving the hollow they protect free.

The current solutions give rise to a thermal bridge between the exterior of the premises and its interior, since the coefficients of thermal transmission of the materials generally used, such as plastic and metals, are high. In addition, in many cases it

25 placed without any coating on the outside and / or inside. They also allow, to a greater or lesser extent, the passage of air and in some cases even water.

Another common drawback of the usual solutions is the low resistance to

wind load, which results in deformations in the drawer that reduce its

30 water tightness and increase air permeability.

In order to improve the behavior against the passage of heat, air and water to

through the drawer, it is generally used to add elements with insulating properties in the placement of the drawer on site, thus increasing the assembly of the

35 blind or window.

The new technical requirements in the construction sector, especially those established in the Technical Building Code, sharpen this need to reduce thermal losses in façade closing elements, and in particular

5 in the drawers of doors and blinds. The limits of air permeability, tightness and wind load resistance are also reduced.

10. EXPLANATION OF THE INVENTION

The invention object of the present document relates to improvements in roller shutter or door drawers, preferably in the form of a straight parallelepiped, p s, p p p p,

p

with an internal axis where the blind or door winds. fifteen

The drawer is usually formed by two testers on its sides, a series of longitudinal profiles and various plates or plates attached to them, thus forming both the supporting structure and the drawer itself.

The claimed components are located inside the drawer; these are rectangular pieces (1, 2 and 3) of adequate section to the hole formed by the drawer (6)

proper and the blind or rolled door, said and the blind or rolled door, superimposed on the inside and and

properly superimposed on the inside

parallel to each of the outer faces of the drawer. These pieces are made of an insulating material, preferably extruded polystyrene and polyethylene foam sheet.

25

The pieces are placed inside the three sides of the drawer that, once correctly placed, are in contact with the enclosure in which it is placed. That is, on the lower face, where the opening for the passage of the blind or door (5) is located, on the back, the closest to the outside of the room where the drawer is located, and the

30 superior, facing the inferior.

The shape of these pieces is preferably rectangular, with section in each case adapted, on the one hand, to the inner face of the drawer where it is placed, and on the other, with

a recess that allows the housing of the door or blind once rolled. 35

The three pieces are in contact two by two, so that the assembly, once placed, constitutes a continuous barrier and without gaps in all sections

transverse of the drawer. If a fourth piece is adopted, it will be in contact only with the upper part, to allow the blind to pass inside the drawer.

5

Additionally, it is contemplated that a fourth piece is added, on the front face of the drawer (4).

10 BRIEF DESCRIPTION OF THE DRAWINGS

To complement the description that is being made and in order to help a better understanding of the characteristics of the invention, a set of drawings is attached as an integral part of said description where

15 not limiting, the following has been represented:

Figure 1.- Shows a view of the blind drawer (6), with the pieces of material

insulator (1,2, 3 and 4) and the groove for the passage of the blind or door (5).

Figure 2.-The pieces of insulating material (1, 2, 3 and 4) object of the invention.

PREFERRED EMBODIMENT OF THE INVENTION

The improvement in the roller shutter drawer or door shown in the figures

25 1 and 2, includes:

(1) A piece of insulating material, of rectangular plan and section shaped so that the face in contact with the inner top of the drawer (6) is

adapts to the shape of this, while the opposite face has a slight

30 in the form of an arc of circumference, to allow the housing of the blind or door once rolled. The width of the piece is such that it covers the entire upper face of the drawer internally, and its length coincides with the total internal length of the drawer.

35 (2) A second piece, also of insulating material, of rectangular plan and shaped section so that the face in contact with the inner side part of the drawer (6) that, once correctly assembled is outside,

image4

adapts to the shape of this, while the opposite face has a recess in

arc shape of circumference, of the appropriate radius and placed in position

5 convenient to allow the housing of the blind or door once rolled. The width of the piece is such that it covers the face internally

inner side of the drawer, being in contact at the top with the part identified with the number (1) and on the bottom with the inner face of the part of the drawer that constitutes its lower closure, and its length coincides with the length

10 total inside the drawer

(3) A third piece, also of insulating material, rectangular and sectional

shaped so that the face in contact with the inner bottom of the

drawer (6) adapts to the shape of this, while the opposite side presents

15 a slight recess in the form of an arc of circumference, to allow the housing of the blind or door once rolled. The width of the piece is such that

internally it covers the lower face of the drawer, from the groove through which the blind passes through the part identified with the number (2), and its length coincides with the total internal length of the drawer.

twenty

(4) A fourth piece, optional, also of insulating material, of rectangular plan and shaped section so that the face in contact with the inner side part of the drawer (6) which, once correctly assembled is inside

adapts to the shape of this, while the opposite face has a slight recess in the form of an arc of circumference, to allow the housing of the blind or door once rolled. The width of the piece is such that

internally covers the side face of the drawer, from the part identified with the number (1) to an area slightly above the groove by the

that passes the blind (5), to allow the passage of this, and its length coincides with the total internal length of the drawer.
