Abstract

The invention relates to a sun shield designed to be mounted in front of a window or door opening in, or on an outer wall, a building or the like, comprising a plurality of lamellas (4) which are and supported by ladder bands (5), and are tiltable. The lamellas (4) are, in their downward direction, defined by a bottom board (9) to which are pivotably connected at least two, at a predetermined mutual distance located arms (10, 11) at each side of the lamellas (4), the opposite free ends of arms (10, 11) being pivotably connected to the edge portion of the opening in question in an area substantially corresponding to half of the height of the opening. The arms (10, 11) have a length position orientation of the lamellas vertically downwards, or vertically upwards and in an intermediate position in which the bottom board (9) will be located at a distance in front of the opening, the lamellas (4) then being either horizontally oriented or tilted to a closed position, so that the sun shield will alternatively function as one of three different types, namely an outer wall Venetian blind, an awning, or a non-adjustable sun shield.

Description

SUN SHIELD

The present invention relates to a sun shield which is designated to be mounted outside and in front of a window opening in, a door opening in, or a front wall of, a building or the like, and which comprises a plurality of lamellas located above each other and supported by ladder bands so that they become tiltable and can serve as a combined outdoor sun shield which in one and the same installation can be used in three different shapes, namely as a sun-blind, or awning, as a rigidly arranged sun shield and as a front wall Venetian blind.

People have since long ago wished to protect themselves against direct sunshine. The oldest shields were constituted by some type of curtain as in today's blinds or shutters. When more permanent buildings were constructed, window shutters with slanting wooden boards were installed to obstruct penetration of the sun light . Those designs where the forerunners of today's ordinary and front type Venetian blinds. Later on there was also developed a non-adjustable sun shield including slanting lamellas which project horizontally above a window opening in a building. In order to obtain the maximum of its hea -repulsing effect the sun shield is placed on the outer wall of the house resulting in the formation of an air gate between the sun shield and the window pane or outer wall in question.

The object of the present invention is to integrate three of the types of the sun shield existing today, namely a sun blind, a front wall Venetian blind, and a non-adjustably arranged blind, so that it becomes possible to utilise the alternative most suitable on each occasion. The features characterizing the invention are set out in the subsequent claims .

Thanks to the invention there has now been provided a sun shield which in an excellent way satisfies the requirement and, at the same time, can be manufactured simply and at a low cost. The sun shield according to the invention comprises a pivotably arranged arm with the aid of which the lamellas forming part of the sun shield can, by use of control means, be brought into the position corresponding to the different alternatives. In a first mode of operation the device according to the invention serves as an awning, the lamellas being tilted to a closed position. In another mode, the arms 5 being in the same position as in the first one, the lamellas are kept in a horizontal position, corresponding to a rigid arrangement and, in a third mode, the device functions as an ordinary wall Venetian blind, the arms being in their lower, vertical position and the lamellas being adjustable between a 10 completely open and a completely closed position. In all of the operational modes mentioned above spring-actuated swingable arms serve as position locks making is possible without any problems to leave the sun shield in an extended position, also in strong wind conditions. The sun shield can, 15 of course, also be bought into an upward-directed, vertical position above the window opening and its control means can include wires, bands, cranks and motors.

A preferred embodiment of the invention is described below, reference being made to the drawings. 2.0 Fig. 1 is a diagrammatic, elevational view showing the sun shield in its upper position,

Fig. 2 is a lateral view of the sun shield shown in Fig. 1,

Fig. 3 illustrates the same sun shield as in fig. 1 and 25 2 in a semi-extended position, the lamellas being tilted to a closed position so that sun shield act as an awning,

Fig. 4 is a perspective view illustrating the sun shield in the position shown in fig. 3,

Fig. 5 is a lateral view showing the sun shield in a 30 semi-extended position, its lamellas being tilted to a closed position, so that it acts as a shutter,

Fig. 6 is a perspective view of the sun shield shown in Fig. 5,

Fig. 7 is a lateral view showing the sun shield in the 35 vertical, downwards directed position, the lamellas being tiltet so as to cut off all incoming sun rays,

Fig. 8 is a front vie of the sun shield in fig. 7.

Fig. 9 corresponds to fig. 7, but the lamellas are in a horizontal position, Fig. 10 is a perspective view of the sun shield shown in fig. 9,

Fig. 11 does, in a diagrammatic lateral view and on a larger scale, illustrate the sun shield shown in fig. 7. As appears from the drawings, and more particularly from the side view in Fig. 11, the sun shield according to the invention comprises a mounting or supporting device 1, and a box 2, inside which ladder bands 5 are secured to rolls 6 on a horizontal shaft 7, so that the lamellas 4 can be tilted by means of a crank, band wire or motor 3.

The box 2 houses bands or wires 8 mounted so as to permit hoisting and sinking of the sun shield. The lamellas 4 are mounted in the ladder band 5 and in the lower part of the device there is a bottom board 9 to which swingable arms 10 and 11 are pivotably attached. The arms 10 and 11 have a bent section 12 making it possible to swing them through 180°. By means of a mounting device 13 the arms 10 and 11 can be mounted adjacent a window or door opening.

Claims

1. Sun shield designed to be mounted in front of a window or door opening in, or on an outer wall of a building or the like, comprising a plurality of lamellas (4) which are located above each other and by means of ladder bands (5) and hoist wires (8) can be tilted and hoisted and lowered, characterised in that the lamellas (4) are, in their downward direction, defined by a bottom board (9) to which are pivotably connected at least two, at a predetermined mutual distance located arms (10, 11) at each side of the lamellas (4) , the opposite free ends of the arms (10, 11) being pivotably connected to the edge portion of the opening in question in an area substantially corresponding to half of the height of the opening, said arms (10, 11) having a length permitting the lamella assembly (4) to assume either a position in which the arms are directed vertically downwards, or vertically upwards or an intermediate position in which the bottom board (9) will be located at a distance in front of the opening and the lamellas (4) being either horizontally oriented or tilted to a closed position, so that the sun shield will alternatively function as one of three different types, namely on outer wall Venetian blind, an awning or a non-adjustable sun shield.

2. A sun shield according to claim 1, characterized in that its arms are adjustable to all positions completely upright and completely extended, the lamellas (4) being either closed or in horizontal positions.
