Description

The subject of the invention is a device for opening blinds or transoms of lanterns of factory buildings with the help of pivotally articulated levers that are interchanged by a common gravity.

In order to make it possible to immediately open a whole row of transoms or louvers with the help of a manual drive from the floor of the workshop, it is necessary to lighten the weight of the fixture as much as possible and balance the weight of the opening louver or transom at the same time.

In the proposed device, this is achieved by the fact that the levers of which the device is composed, form in aggregate a pendulous system, due to which they, together with the traction, serve as a counter-weight for the louver or transom.

This is achieved, according to the invention, by double-arm levers that are articulated at the end points with levers connected with transoms and at mid-points with levers rotated around the axes on a fixed support.

In FIG. 1 shows a general view from the inside of the louver of a lantern of a factory building equipped with such a device; FIG. 2 is a cross section of one wing of such a lantern; FIG. 3 is a detailed view of the proposed fixture (node A of FIG. 2); FIG. 4 shows a section along (ab) of FIG. 3; FIG. 5 shows the node B in FIG. one; FIG. 6 is the same as in FIG. 5, but in the plan; FIG. 7 shows the node C in FIG. 1 and 2; FIG. 8 is a node D in FIG. 2

As shown in FIG. 3, a vertical section 1 of one section of the lamp, moving in the guides 2 and therefore remaining at a constant distance from the column 3 of the lamp. , is pivotally connected at point 4 with the lever 5. The end 6 of this lever is pivotally articulated with one end of the lever 7, the other end of which is connected at point 8 to the shutter 9 of the louver (or transom).

In the middle point 10, the lever 5 is connected pivotally with the lever 11, the free end of which is pivotally

attached at point 12 to a fixed support, in this case, a rack 3 lamp.

In the embodiment shown in FIG. 3 position of the sash 9 shutters closed.

To open them, you need to move tg 1 down. In this case, all three levers 11, 5 and 7 will move to the position shown in FIG. 3 by a dotted line, n point 8 will switch to position 8a, at which the transom or louver shutters will open.

To implement the simultaneous opening of all or several sections of a single wing, the vertical lights 1 of several sections are controlled from a common shaft 13 (Fig. 1 and 2) through nodes B, C and D by means of an endless chain 14 hanging downwards.

The lower ends of the puller rod 1 are provided with toothed racks 15 (Figs. 5 and 6), which engage with the toothed rims 16 mounted on the shaft 13, which is designed to facilitate the construction of pipes. In one particular place (node C), the shaft 13 is connected by a bevel gear 17, 18 (Fig. 7) with a shaft 19 perpendicular to it (Fig. 2 and 7).

At the end of hall 19, there is a gearbox 20 (node D — FIGS. 2 and 8) with a sprocket 21, through which endless chain 14 is thrown.

By turning the wheel 21 by the chain 14 from below, the shaft 19 turns through a bevel gear 17, 18, the shaft 13, which raises or lowers the slats 15 with t-rims I, thus opening or closing the transoms or flaps of the factory building lanterns.

The subject matter of the invention.

A device for opening shutters or transoms in factory buildings with three arms pivotally articulated between themselves, rearranged by a longitudinal thrust, characterized in that the lever 5 pivotally attached to the longitudinal t he lever 5 is connected at the end with the lever 7, which is pivotally attached at the point 8 to the louver or transom, and in its middle part - with the lever 11, rotated around the axis 12, located on a rigid support.
