[0001] The subject of this invention is the box of an overlay-type roller shutter, furnished with a snap-lock enabling closing of one of two adjacent service covers.
[0002] The known boxes of roller shutters used to have their service covers fixed from underneath or from front. Such type of a box is known from the German publication of the patent application Nº DE 10 2009 000 643A1. Opening and/or closing of the covers installed on the box is performed making use of a profiled snap-fastener furnished with spring pins snapped in profiled grooves on the covers.
[0003] The object of this invention is construction of the box of an overlay-type roller shutter, enabling opening of the box in two planes, making use the same components, whereas either the left cover and/or the right cover has the same cellular structure. This is solved by the box according to claim 1.
[0004] The box of an overlay-type roller shutter, of a rectangular prism form, constructed of plastic cellular walls separably joined, two opposite side walls of the box are of a twin structure, characterised in that the shaped-profile slot separably joined with the side cellular wall and/or with the bottom cellular wall is set in the inner corner of the said box, the slat in its cross-section perpendicular to the lengthwise axis has the shape of a near isosceles right-angle triangle, whereas at the side of the slat, there is a T-shaped guide placed inside the recess of the bottom wall or the sidewall, whereas at the other side of the triangle, there is a catch of a near V-shape, whereas in the upper parts of the walls, there are hinges placed in the corners of the top cellular wall. The shaped-profile slat can be joined interchangeably with the cellular side wall or with the cellular bottom wall by the catch, whereas the guide can be placed in the other recess. The recesses situated at the ends of the walls perpendicular to each other, are of the same shape, and they have in the cross-section the shape of a trapezoid that one wall of which has the opening.
[0005] The advantage of a box of an overlay-type roller shutter, according to this invention, is the possibility of opening the box in its two planes, making use of the same cellular components, whereas the left cellular cover and/or the right cellular cover are the same shape-product, that enables to lower production costs and/or to reduce the number of components variety.
[0006] The cellular structure of a box of an overlay-type roller shutter increases its rigidity and/or improves parameters of the thermal and/or acoustic insulation. The structure of the box facilitates the usage of its steel reinforcement, and provides a simple way of fastening the box to a doorhead using specific ties intended for the purpose. Installation of the assembled box onto the window head is facilitated with the suitable snap shape. A skew shape of the box's bottom profile facilitates drainage of water from the inside of the roller shutter, whereas the smooth surface of outer walls of the box makes it possible to glue it with Renolit.
[0007] The subject of this invention is shown in the drawings as an exemplary make; in the Fig. 1, the cross-section of the assembled box of an overlay-type roller shutter is shown; in the Fig. 2, the cross-section view of the box of an overlay-type roller shutter, having the bottom cellular wall open, is shown; in the Fig. 3, the cross-section view of the box of an overlay-type roller shutter, having the side cellular wall open, is shown; in the Fig. 4, the axonometric view, from the box interior, of the box of an overlay-type roller shutter, is shown; in the Fig. 5, the cross-section of the shaped-profile slat, perpendicular to its lengthwise axis, is shown; in the Fig.6, the axonometric view of the shaped-profile slat, is shown; and in the Fig. 7, the joint of the cellular walls made using the shaped-profile slat, is shown.
[0008] As it is shown in the drawing, the box of an overlay-type roller shutter of a rectangular prism form, consists of separably joined cellular walls 1, 2, 3, 4, of which two opposite side walls 1, 3, have a twin structure. Inside the inner corner 5, there is the shaped-profile slat 6 separably joined with the cellular wall 3 and/or with the cellular wall 4, the slat 6 in its cross-section perpendicular to its lengthwise axis 7 has the shape of a near isosceles right-angle triangle. One side 9 of the shaped-profile slat 6 has the T-shaped guide 8 placed inside the recess 10, whereas at the other side 11 of the triangle, there is a catch 12 of a near V-shape. In the upper parts of the walls 1, 3, there are hinges 13, 14, placed in the corners 15, 16, of the top cellular wall 2. The shaped-profile slat 6 can be joined also with the wall 3 by the catch 12, whereas the guide 8 can be placed in the recess 10'. The recesses 10 & 10', situated at the ends of the walls 3 & 4 perpendicular to each other, are of the same shape, having in a cross-section the shape of a trapezoid, one wall 17 of which has the opening 18. The skew walls 19, 19', of the recesses 10 & 10', are inclined to the bases 20, 20', at an angle αa equal to 45°, whereas the skew walls 21, 21', are inclined to the bases 20, 20', at an angle β equal to 67.5°.
