United States Patent 6 VENETIAN BLIND FOR MOTOR CARS Bror Karl Samuelsson, Lulea, Sweden Application March 30, 1954, Serial No. 419,847

1 Claim. (Cl. 160-169) The present invention relates to a blind for motor vehicles. The blind comprises a number of rectangular lamellae of sheet metal, plastic or some other suitable material and is mainly characterized thereby that the lamellae are suspended through flexible means on two vertical or approximately vertical rods, which are displaceable in the longitudinal direction thereof and pass through elongate apertures provided in the lamellae in the lateral direction thereof. The lower rod portions rest in guide means provided below the blind, the blind thus, through displacement of the rods in the guide means, being vertically adjustable as well as collapsible so that the lamellae will be resting with their side portions against each other in a bed with U-shaped cross section provided below the blind in the longitudinal direction thereof.

A blind according to the invention is described in the following text and illustrated in the accompanying drawing, in which- Fig. 1 is a side view of the blind and Fig. 2 shows the latter fitted in a window of a motor car.

Referring now to the drawing, the numeral 1 designates rectangular lamellae of sheet metal, plastic or some other suitable material. The lamellae are suspended by flexible step ribbons 2 arranged at some distance from the lamellae ends. Numeral 3 designates elongated apertures provided in the lateral direction of the lamellae at some distance from the ends thereof. The lamellae 1 are slipped over two vertically or approximately vertically directed rods 4 passing through the apertures 3 of the lamellae and fastened at their tops to a plate 7 having approximately the same dimensions as the lamellae 1. This plate 7 consists of sheet metal, plastic or some other suitable material and is designed so as to yield a certain resistance against bending. 8 designates a bed with U-shaped cross section and upright, opposed side walls and is intended =for mounting in the lower part of a. window opening. Fastened in the bottom portion of the bed 8 are downwardly directed sleeves 9, in which the lower part of the rods 4 can be vertically adjusted. The sleeves 9 are arranged between the body plate and the coating of a motor vehicle and their lower end portion are provided with braking means '10 serving to retain the blind in a vertical position to which it has been adjusted in the window. By way of example, the braking means 10 may consist of a ring of elastical material placed in a nut, which is provided with an inwardly protruding flange and screwed on to the downwardly extending end parts of the sleeves 9, the inner periphery of the braking ring exerting a certain pressure and friction against the rod 4.

When a window provided with a blind according to the invention is to be screened ofl, the plate 7 is moved upwards, the step ribbons 2 secured to said plate and carrying the lamellae 1 at a certain vertical distance from one another then bringing the lamellae into such a position that the window is screened oft entirely or partly. When no screening off is desired, the plate 7 is moved downwards to collapse the blind, the lamellae 1 thereby being brought to rest with their side portions against one another in the bed 8 at the lower part of the window Opening.

In the first hand the blind according to this invention is intended to serve as a protection against the sun rays and, since the lamellae of the blind are horizontal, the sun rays are effectively screened ofl due to their angle of incidence relative the windows of a motor vehicle. A 'further advantage with the blind is that, when collapsed, it does not prevent a person sitting in the car from putting his arms through an open car window.

The blind can be operated by a single movement of the hand, but may also be operated by means of electrically, pneumatically or hydraulically actuated devices. If such blinds are provided in bus windows, it might be advantageous to equip them with operating means of such a kind that the blinds can be operated automatically in groups and that each individual blind can besides be manually operated.

Of course the invention is not confined to the embodiment described in the foregoing text and illustrated in the drawing, but may be modified in several ways without abandonment of the inventional spirit.

I claim:

A Venetian blind for motor vehicles, comprising a plurality of rectangular lamellae of sheet material, a pair of substantially vertical laterally spaced rods, flexible means for suspending said lamellae from said rods said lamellae each having two spaced elongate, laterally extending apertures, said rods each extending through one of said apertures of each rod respectively, guide means for receiving and holding the lower end portions of said rods, said guide means being disposed below the lamellae of said blind, said rods being vertically displaceable in said guide means for adjustment of said lamellae through collapse and tightening of said flexible supporting means, said means for retaining said rods in adjusted position in said guides and an elongate bed having a U-shaped transverse cross section provided underneath said blind and extending in the longitudinal direction of said lamellae for receiving said lamellae of said blind when said rods are retracted within said guide means.
