Device for clamping and sealing blackout curtains. .-,

The firing concerns a device for clamping - I and sealing blackout curtains on windows with a Terminal strip consisting of a leg to be attached to the side, top or bottom of the window and a leg that is sprung against it Legs to clamp the gate slope edges ». - - - ■ '. ■

Such known devices have the disadvantage _? .-that to create-the cushioning respectively. Bias voltage of the two clamping strips against each other leg is always to be incorporated in-· separate operations leather organs or the like must be provided _s ,, the at several locations along the. Clamp legs are to be determined. This makes these darkening devices expensive and does not allow quick, economical production. _--.

Accordingly, the task of the innovation is to remedy the aforementioned ET disadvantages and to create a Klammvorriehtung? which can be easily operated or used \ ^: and'adjustable next to window openings * ■ ^:

To solve this problem, it is proposed, according to the new, that in the device mentioned above, the two clamping legs through the two halves of a Langge.streckten.p

separated on one side and produced by extrusion Hollow bodies are formed from elastic plastic, wherein the non-attached half with a longitudinal outwardly protruding approach as a lever arm for spreading the clamping legs is provided. Furthermore, the hollow body can have an essentially rectangular cross section, the clamping limbs of which forming sides converge roughly conically towards the dividing line *

For a better understanding of the innovation, an in the attached drawings illustrated embodiment explained in more detail. Show Bs *

Fig. 1 is a sectional side view of the device after firing:

ig. 2 a perspective view of the device according to S ¹ Ig. 1.

The two KeImmschenkel 1 and 2 are advantageous through the two halves of an elongated and unilateral formed along a dividing line 3 separated hollow body, which in the extrusion process cheap and easy from elastic Plastic is to be produced. The ones not on the ribbon window 4 attached half 2 is with a longitudinal outward protruding approach 5 provided as a lever arm. This is the longer one

2. ■■■. ■ .- ■■

the movable clamping leg / forming side, on the side facing away from the dividing line 3, as a lever arm approach. . The dividing line 3 is created after pressing the hollow body by cutting it open or in some other way, so that after the cutting open there is already a pretension between the two legs 1 and 2 along the dividing line "3 _" which is sufficient to clamp the blackout curtain firmly. Bs however, it is also possible, right when the hollow body is pressed

_ 3 -

to produce this dividing line with an appropriate shaping of the press nozzle. To operate the device, which is described as a short Clamping piece or can be designed as an elongated clamping rail, one presses on the lever arm 5 and thus spreads it the legs 1 and 2 at their free ends to open the blackout curtain to insert or to pull out for removal »".

As can be seen particularly from Fig. T, the Hollow body separated on one side, an essentially rectangular one Cross-section, with the clamping legs 1 and 2 in Converge approximately conically towards the dividing line 3.

To attach the fixed leg 1 on the window side wall are extending in the longitudinal direction. Breakthroughs 6 and 7 are provided once in the fixed leg and on the other in the movable leg 2 at the desired intervals * whereby the openings in the movable clamping leg have a larger diameter or width than those of the leg 1 to be attached or openings 7 are brought into the longitudinal openings β for the purpose of fixing the Kle.mmvorrichtung and are more easily screwed from the outside. ^D ue to the designed as oblong holes openings, it is possible to attach the clamping device adjustable on its mount base.

The wall of the to be determined leg 1 is slightly curved in the direction of the hollow body interior is formed _s so as to form a smooth mounting surface of a small cavity 8 after placing the clamp * sets When tightening the fixing screws in the holes β underlying the

Leg 1 flaoh against the fastening surface 4, whereby the KLa.mmdru.ek between the "two legs at the dividing line 3 increased due to this deformation and thereby a greater clamping force is caused.
