Device for covering large window areas

The ^ furnace relates to a device for covering large window areas by means of fabric strips arranged to be adjustable on the inside of the room, in particular for Greenhouses "

In the case of large window areas, you should be inclined or horizontal extend, it is difficult to protect the room from light and the windows entirely or to be partially covered from the inside.

It is known to cover the window surfaces from the outside with simple mats made of straw or thin wooden strips, which usually have to be placed or removed by hand, especially since the glass surfaces are mostly not entered can be. In addition, the weather conditions make the mats unusable at an early stage and have to go and do it to be replaced again.

It is also known to have panels of fabric on the inside of the

Provide windows that are removed from a take-up roll be pulled and rest on tension wires that are parallel are drawn to the window surfaces. The webs of fabric are wound up using a winch. This covering device is very primitive and prone to failure, which is why it does not work properly continuously is guaranteed.

The purpose of the innovation is to provide a device for covering large window areas on the inside of the room to create adjustably arranged strips of fabric that flawlessly cover the window areas and reliable continuous operation are guaranteed. According to the new invention, this is achieved by that τ β de fabric "is yours a Bssls 3.a Ber ^ isli one side of the window frame attached and at its other end with a strand on each side of the Length of fabric and connected parallel to this and to the window surface by means of an endless chain guided by swivel pulleys is, the chains are driven synchronously and the fabric web in a position of the chains on the Window area is streamlined and in the other southern division sags.

Several lengths of fabric can be attached to a window front each other be provided, the one from the outer and 3e chains arranged between two lengths of fabric

adjusted. This makes it possible to use several lengths of fabric to cover the entire window front at the same time to cover.

The panels may be provided at their longitudinal sides in the most uniform possible intervals with predetermined members, which run on the chains and are guided by these. In this case, the roller members can be arranged opposite one another in pairs on the two long sides of a fabric web and connected to one another by means of a cross member which serves as a support rod for a fabric web section. In this way, the depth of the sagging of the individual lengths of fabric can be limited and the space available.

In detail, the arrangement can be made so that one pulley of several or all of the chains window front are mounted on a continuous, electric motor-driven shaft, while the other TJmenkrolle are individually adjustable and lockable in the longitudinal direction of the chains. This enables to tension the individual chains in the desired manner.

In the drawing, the firing is on the execution version of a greenhouse, namely demonstrate

In the illustrated embodiment, the greenhouse with 10, its penster surfaces with 11, the fabric marked with 12 and the endless chains serving as a means of transport for the web of material marked with 13 »

The greenhouse 10 has two sloping penster fronts that converge in the porm eirss gable. The penster surfaces themselves are supported by a support structure 14. On the inside of this support structure a bearing frame 15 is arranged in the area of the gable, on which in association with the two penster fronts jo a continuous shaft 16 is mounted on which in Gate-specific spacing rolling rollers 17 for the endless Chains 13 are attached.

In the lower area of the two penster fronts, corresponding pulleys 18 are free for each chain 13 rotatably mounted, which are adjustable and lockable in the longitudinal direction of the chain (Pig. 3).

So much for a common drive for several or all Chains 13 of a penster front is provided, is also

if there is a means in the lower area of the window front an electric motor 19 driven .drive shaft 20 stored, (Fig. 4), which runs between the strands of the endless chains 13 and is attached to it and strife engaging in the links of the chains acts positively on the chains, so that the latter Drive shaft assigned Seirfcen sjnenron driven will.

The fabric webs 12 are fastened with their one end 22 & m bearing frame 15 in the area of the upper deflection rollers 17 and extend in the tensioned state to the lower end of the window front. At its other end 23, the fabric web is connected to one of the endless chains 13 on both sides, preferably by means of a rod which extends between the chains associated with the fabric web and is connected to them. In the one position of the chains facing the fabric web, the S.off web is tensioned on the window surface, while in the other position of the chains it sags freely downwards.

To reduce the slack in the length of the fabric, the length of the fabric is as evenly spaced as possible with roller links on both of its long sides 24 provided, which run on a strand of the endless chains and are guided by them.
