Problems solved by technology

[0007] These systems all require an additional operation on the tubes to weld the lugs to the areas where they mate with the slots, adding to the cost
[0008] Furthermore, in the above systems, the lugs of the above linkages are subject to torsional loads but can break due to lug-tube connection fatigue

Embodiment Construction

[0030] Detailed Description of Preferred Embodiments

[0031] As stated above, the present invention relates to a mechanism for joining together an accessory for the operation of a wrap-up curtain, the handle 1 of which is connected to the crank 2 which, due to the specific structure of both, enables the crank to Reliably plugged into the tube 3.

[0032] The above-mentioned tube 3 preferably has a circular outer circumference 3.1, while the inner circumference into which the crank 2 and the transmission member 3 are inserted has a circular arc segment 3.2.1 and a straight segment 3.2.2.

[0033] The above-mentioned crank 2 has an outer circumference 2.1 matching the inner circumference 3.2 of the tube 3 on the end connected to the above-mentioned tube, and the circular arc segment 2.1.1 and the straight line segment 2.1.2 are arranged to be the same as the circular arc of the inner circumference 3.2 of the tube 3 Paragraph 3.2.1 coincides with straight line paragraph 3.2.2. ...

Abstract

The invention relates to coupling means for accessories that are used to operate roller blinds, which, owing to the special configuration thereof, enable the insertion-fitting of the tube of the handle in relation to the transmission mechanism or of the actuation handle in relation to the tube. In addition, according to the invention, the forces are transmitted between the tube of the handle and the mechanism to which said tube is connected, such that the coupling elements do not have to withstand said forces. As a result, the coupling elements can be produced from light materials and with minimum force-supporting requirements, such as to form a lighter mechanism.

Description

technical field [0001] The object of the present invention is to provide a connection mechanism for operating accessories for winding blinds, which, due to their specific structure, ensures a reliable insertion between the crank tube and the transmission mechanism or between the drive crank and the crank tube. [0002] Furthermore, this particular structure ensures that the loads are transferred from the crank tube to the mechanism connected to said tube, freeing the connection mechanism from carrying said load. [0003] In this way, the above-mentioned connection mechanism is made of lightweight materials, which has low requirements on load bearing, and thus a lighter mechanism can be obtained. [0004] The invention is also characterized in that the connecting mechanism can clamp the above-mentioned crank tube to the transmission member or the drive crank. Background technique [0005] It is known in the prior art that a tube can be used to connect the transmission member...
