Embodiment Construction

[0047] Figure 1 shows an exploded view of the chain operator of the present invention. The operator comprises a cast metal housing 1, for example a die-cast zinc housing. The metallic housing 1 has a substantially planar bottom wall 2 . A substantially cylindrical wall 3 extends from the inner side of the bottom wall 2 . The cylindrical wall 3 defines a hole in which the spindle 4 is located in a fixed manner. The end face 5 of the cylindrical wall 3 forms a bearing surface for a sprocket 6 arranged on the spindle 4 . The sprocket 6 forms part of a sprocket and gear 7 assembly. In the preferred embodiment, the assembly is formed by joining together two separate parts in fixed mechanical relationship, but it will be appreciated that it could also be integrally formed or separate parts linked only in a rotational direction.

[0048]In recesses in the manipulator housing 1 there are two loosely fitting journal bearings 8 and 9 . These bearings serve as support for the opposi...

Abstract

A stop member for an operator chain in a chain operator, wherein the operator chain has a width, rivet holes and rivets, constitutes a pin arranged in a rivet hole not occupied by a rivet in the operator chain, wherein the pin has a length exceeding the width of the operator chain. The pin can be cylindrical with a diameter corresponding essentially to that of the rivet hole, and the diameter of the pin can be slightly smaller than that of the rivet hole, so as to be loosely held in the rivet hole.

Description

[0001] The present invention is a divisional application of the Chinese patent application 200480002811.X filed on February 13, 2004 entitled "Chain Manipulator Shell". technical field [0002] The invention relates to a chain operator shell, in particular to a chain operator shell for manual operation of windows. Background technique [0003] Window chain operators are widely known. Such chain operators typically include: a chain of operators housed in a box; a sprocket that engages the chain and drives the chain into and out of the box to open and close a window attached to one end of the chain. The sprocket is integral with or at least directly connected to a coaxial gear which is connected to a reduction mechanism. The simplest form of a reduction mechanism is a worm gear arrangement, and the gear constitutes a worm wheel that cooperates with a worm. Alternatively, the worm wheel may constitute the sun gear of the planetary reduction gear. The sprockets and gears are ...
