FR2789728A1 - ROLLER SHUTTER DEVICE, FRACTIONED IN TWO PARTS, WITH VARIABLE WINDOW - Google Patents

Abstract

The roller shutter is divided into two upper (2) and lower (1) sections which are connected together to allow the forming of a window between them. The window height can be adjusted by operating the shutter reeling system. The shutter sections can be connected by cables or lines.

Description

Roller shutter device, split into two parts, with window

  variable. The present invention relates to a rolling shutter device applying

  on all types of roller shutters traditionally existing in the building.

  The existing shutters are constructed from a single panel (with plastic slats, steel, aluminum or wood), wound on an axis. They take place to descend and close an opening. You can currently lower the quarter shutter (see Figure 1.1), half (see Figure 1.2), three-quarter (see Figure 1.3), all (see Figure 1.4) or as desired, so as to obstruct the upper part of the opening, then the whole. The disadvantage of this system is that the shutter, lowered by a quarter or half hides your view towards the outside while the person outside sees your interior through the unmasked part of the bottom. Descended even three-quarters or more, it will let in the cat

  neighbors, dead leaves, etc. or on the contrary will let the dog out.

  The device according to the invention overcomes these drawbacks. The present invention is a roller shutter divided into two parts, allowing an opening, adjustable, between these two parts. By activating the unwinding system, the first part, called "lower part" (1) and whose height can be chosen by the customer, will descend (see figure 2.1) and then continue to the bottom (see figure 2.3) or not completely down if you want to let the cat out (see Figure 2.2). Simultaneously, the second part, called "upper part" (2) will run with delay, thus leaving a "window" whose height is also chosen. By continuing to activate the unwinding of the shutter, the upper part continues to descend (see figure 2.4) (the lower part having already arrived at the bottom), and the "window" narrows at will until completely obscured (see figure 2.5 ). Conversely, by activating the winding of the shutter, the upper part (2) being rolled up, the window will appear again (see figure 2.4) then the lower part will go up

  until the shutter is fully wound up.

  Method of implementation: Roller shutter with horizontal slats, the panel of which is divided into two parts: upper part (2) and lower part (1). The window part can be obtained by connecting the upper part (2) to the lower part (1), for example by means of a flexible steel blade (to allow it to be wound on

  rolling) linked to the lower part and retracting into the upper part when this

  ci is lowered, (or conversely be fixed on the upper part and enter the lower part) see figure 3. An opening Cl is made in the ends of the upper batten (la) of the lower part (1) of the shutter and in the ends of the lower batten (10) of the upper part (2) of the

  flap and a slot allowing just the passage of the steel blade C5.

  The opening and the slot make it possible to pass the steel blade of connection C5 with its

  high stop C3 and its low stop C4 as well as possible reinforcements of "under-

  These stops can be crimped onto the steel blade or cut into them like arrows in the shape of the stops. This blade looks like a steel tape measure or a band saw blade. steel blades will

  dimensioned after strength study according to the models and their dimensions.

  A removable cap C2 closes the opening and the CI slot.

  A passage C6 of the width and thickness of the stop C3 will be made in the shutter slats of the upper part, so that, when the upper part of the shutter descends on the lower part which is in contact with the ground, the stop C3 retracts into these slats by guiding the steel blade of connection C5 which will disappear as the upper part of the shutter unfolds (see Figures 2.4 and 2.5). Conversely, the C5 blade will reappear on winding. The length of the C5 steel slats determines the height of the window and can therefore be chosen according to each need (see Figures 2.2 and 2.3). The flexible, stainless steel link blade can be replaced by a flexible single-strand stainless steel cable with crimped stops. The connecting blades or cables can be made of another material, as long as they are rigid in the deployed position and are flexible enough to obtain the wound position. The U-shaped guides of shutters installed on the vertical frames of the openings to be fitted will be wide enough to hide and protect the steel blades from

liaison.
