(54) SUN-PROTECTIVE DEVICE

one

The invention relates to the construction and can be used in the construction of sun-protection devices.

The known sun-protection device is a light aperture, including shading plates pivotally connected to rigid parallel connections, in which one of the ends is hingedly attached to the supporting elements of the light aperture with the possibility of rotation in a plane parallel to the light aperture, and their free ends are connected by a tie 1.

In the known sun-protection device, the spatial rigidity of the structure is determined by the rigidity of the plates, which, in connection with the absence of a closed frame, which perceives the loads acting on them, in particular wind, are thickened. This entails a significant increase in the metal structure, the deterioration of its thermal performance and performance.

In addition, the disadvantage of this device is the inconvenience of fixing the known sunscreen device in the working position when attaching its rigid connections to the upper part of the aperture. Between

However, as practice has shown, it is precisely such anchoring that makes it possible to obtain the most favorable in all respects the variant of the arrangement of such a sunscreen device, for example, in the loggia of a residential house. The experience of using sun-protection devices of known design shows that when folding shading plates into a bag without translation to a horizontal position, deformations usually take place - and damage to their end edges as a result of contact of the latter with rigid connections.

The aim of the invention is to increase the spatial rigidity, reduce the metal structure, provide ease of operation, as well as increase reliability and avoid damage to shading plates when they are folded into a bag.

This is achieved by the fact that in a sunscreen device containing shading

0 plates connected by spherical hinges with rigid parallel links, one of the ends of which is hinged to the supporting elements of the aperture, spherical hinges are placed on the ends of shading plates, and the free ends of hard parallel links are interconnected by a tie attached to them hinged, with clamping devices mounted in the lower part of the aperture, made, for example, in the form of folding brackets, for securing the tie bar in the working position of the sun-protection device. In addition, a rotation rail with a lining of friction material is hinged to the side edges of the shading plates, and a box-shaped clamp is mounted on the aperture support elements to accommodate the lining in the working position of the sun-protection device, and a size-appropriate slot is made in one of the latch walls lining and its position with horizontal shading plates. FIG. 1 shows a sunscreen device in the working position, general view; in fig. 2 - the same in the process of folding; in fig. 3 shows section A-A in FIG. I when the shading plates are inclined; in fig. 4 - the same with their horizontal position at the moment when the staff slides out of the fixture for folding the shading plates into the bag; in FIG. 5, view B in FIG. 3; in fig. b - view B in FIG. 4 with retracted flaps with clamping screws; in fig. 7 a section of YYY in FIG. 5. The sun protection device contains shaded plates 1 with spherical e, elements 2, which are placed in the sockets 3 of rigid parallel links 4 located at the ends along the longitudinal axis of the shading plates 1. One of the ends of each rigid link 4 with a hinge 5 attached to the supporting elements of the light aperture can be rotated in a plane parallel to the light aperture, and the opposite free ends are made with hinges 6 attached to the ends of the stud 7, which is placed at the working position of the sunscreen device in folding brackets 8, equipped with clamping screws 9 and attached to the bottom of the light aperture. To one of the rigid connections 4 there is attached a ha ha 10, passed through blocks II installed in the upper part of the light-receptacle. To the side edges of the shaded plates 1 with spherical elements 2 pivotally attached rail 12, the lower end of which is provided with a lining 13 of friction material. When the sunscreen device is in the working position, the cover plate 13 is placed in the cavity of the box-shaped retainer 12 attached to the building structure in the lower part of the light aperture, and is in close contact with its walls.

In the lower part of one of the walls of the box-shaped retainer 14, viral 0 1a slot 15,

Claims (2)

Aperture elements, characterized in that, in order to increase spatial rigidity, reduce metal consumption, are provided so that the lining 13 can be removed from the retainer only when the shading plates I are horizontally positioned. The bottom of the box-shaped retainer 14 provides the lining 13 of the rail 12 with the horizontal position shading plates 1. When installing the sun-protection device in the working position, the lining 13 of the lath 12 is inserted through the slot into the retainer 14, after which the straightening 7 is strengthened in the internal cavity of the folding brackets 8 using clamping screws. The shading plates 1 are rotated to regulate the amount of solar radiation entering through the light aperture using a lath 12. Fixing 1 hch, the angle of rotation of the shading plates 1 is provided by friction of the lining 13 against the wall of the box retainer 14. Folding the shading plates 1 into the bag when the sunscreen device is not in operation, it is carried out with the help of the thrust rod 10. In this case, the clamping screws 9 are pre-loosened and the folding brackets 8 are retracted, releasing the tightening 7. At the same time, the shading I in a horizontal position, installing the cover plate 13 of the rail 12 against the slot 15 in the wall of the box-shaped retainer 14, and thus providing its removal from the inner cavity of the retainer 14. The invention will improve the spatial rigidity of the structure due to the presence of a frame formed by rigid parallel links and lower straightening, which makes it possible to reduce the thickness of the shading plates and the Sun 3est & amply reduce the intensity of the metal. The presence of hinged brackets with clamping screws, fixed in the lower part of the light aperture, allows you to quickly and reliably fix the sun protection device in the working position. The new design of the box-shaped retainer, in the inner cavity of which there is an overlay of the turn strips of shading plates, makes it possible to prevent their damage when folding into the bag, thereby ensuring operational reliability and durability of the design. Claim 1. Sun-protection device containing shading plates connected by means of spherical hinges with rigid parallel links, one of the ends of which is hingedly attached to the supporting element of the EI NII of ease of operation, spherical hinges located on the ends of shading plates connections are interconnected by a stitch hinged to them, with clamping devices installed in the lower part of the aperture to secure the stitch in the working position of the sun aschitnogo device. 2. The device according to claim 1, characterized in that the lateral edges of the shading plates are pivotally attached to the turn rail with an overlay of friction material, and a box-shaped fixture is mounted on the supporting elements of the aperture, in one of the walls of which a slot is made corresponding to the dimensions of the overlay and its position when the shading plates are horizontal.
