Embodiment

[0015] Embodiment: A gravity-balanced folding mechanism of an external sunshade device for windows

[0016] Such as Figure 1~Figure 3 As shown, the mechanism includes four rectangular sun visors with the same shape, size and weight, namely the first rectangular sun visor 1, the second rectangular sun visor 2, the third rectangular sun visor 3 and the fourth rectangular sun visor Visor sheet 4 (see figure 1 ). The four rectangular sun visor sheets are arranged on the outside of the window 9 from top to bottom in use (see figure 2 ), wherein the upper side of the first rectangular sun visor sheet 1 is hinged in the order from top to bottom (that is, the upper side of the first rectangular sun visor sheet 1 is hinged on the wall or outer wall or window at the top of the window when installed, see figure 1 ), the lower edge of the first rectangular sun visor sheet 1 is connected to the upper edge of the second rectangular sun visor sheet 2 through a hinge 10 (see figure 1 ),...

Abstract

The invention discloses a gravity balancing and folding mechanism of an external solar protection device for a window. The gravity balancing and folding mechanism is characterized by comprising four rectangular solar protection plates with same shape, size and weight, wherein the upper edge of the first rectangular solar protection plate is hinged, the lower edge of the first rectangular solar protection plate is hinged with the upper edge of the second rectangular solar protection plate, the lower edge of the third rectangular solar protection plate is hinged with the upper edge of the fourth rectangular solar protection plate, and the lower edge of the fourth rectangular solar protection plate is hinged. Two ends of the lower edge of the second rectangular solar protection plate and twoends of the upper edge of the third rectangular solar protection plate are provided with idler wheels or sliding blocks which are arranged on vertical guider rails at two sides of the window, the tops of the guide rails are provided with rotating wheels, one transmission belt or transmission rope bypasses through the rotating wheels, one end of the transmission belt or transmission rope is connected with the lower edge of the second rectangular solar protection plate, and the other end of the transmission belt or transmission rope is connected with the upper edge of the third rectangular solar protection plate. Compared with the traditional movable solar protection device, the gravity balancing and folding mechanism has a simple structure, and has the advantages of good balance property, flexibility of opening and closing and convenience for use because rectangular solar protection plates at two ends of a fixed pulley system have same weights and form a balance system.

Description

technical field [0001] The invention relates to a sunshade device for a window of a building, in particular to a gravity balance folding mechanism installed on the outside of the window of a building. The mechanism utilizes the principle of gravity balance to achieve the purpose of easy opening and closing. Background technique [0002] Install sunshade devices on the outside of building windows to block sunlight and ultraviolet rays, so as to achieve the purpose of sunshade, cooling and energy saving, which is the function of all window external sunshade devices. There are many products of existing external sunshade devices for windows, such as sunshade roller shutters, sunshade window covers and awnings, etc., wherein the first type of products can receive or block sunlight and ultraviolet rays by opening and closing, while the first type Class II products are installed in a fixed manner and can only partially block sunlight and ultraviolet rays. Obviously the second typ...
