    1 A WINDOW CHAIN WINDER FIELD [0001] The present invention relates to window chain winders and more particularly to winder chain winders that provide for alteration of the maximum length of chain to extend from the body of the winder. BACKGROUND [0002] Window winders include a body within which there is mounted a sprocket. The sprocket drives a chain between an extended position and a retracted position, with the outer end of the chain being provided with a mounting plate to be fixed to the pivoted window panel. Examples of such chain winders can be found in the specifications of Australian Patent Applications 2010201144 and 2010101266. [0003] A disadvantage of the above discussed window winders is that they can be difficult in respect of changing the abovementioned maximum length. A further disadvantage is that frequently the adjustment mechanism does not directly engage the chain. OBJECT [0004] It is the object of the present invention to overcome or substantially ameliorate at least one of the above disadvantages. SUMMARY [0005] There is disclosed herein a window chain winder, the winder including: a hollow body; a sprocket located in the body and to be rotatably driven about an axis: a chain engaged with a sprocket so as to be moved thereby between a retracted position at which the chain is at least substantially located in the body and an extended position with a portion of the chain extending outwardly of the body, the chain having an abutment; an abutment engaging member selectively operable to engage the abutment, the engaging member being mounted in the body and movable between an abutment engaging position and an 2 abutment non-engaging position, with the chain extending by a first maximum length from the body when the engaging member is in the non-engaging position, and a second maximum length when the engaging member is in the engaging position, the first maximum length begin greater than the second maximum length; and wherein the abutment engaging member is captively located internally of the body and is moved along a predetermined path between the engaging and non-engaging positions.

    5 DESCRIPTION OF EMBODIMENTS [0032] In the accompanying drawings there is schematically depicted a window chain winder 10. The winder 10 includes a hollow body 11 including a top (front) portion 12 and a rear panel 13. Located internally of the body 11 is a sprocket 14 that is rotatably driven about a sprocket axis 15 by a user causing rotation of the handle 16. The handle 16 drives a pinion gear, that in turn drives a gear drivingly connected to the sprocket 14. [0033] Engaged by the sprocket 14 is a chain 17 that includes a chain portion 18 and a mounting member (plate) 19. [0034] The chain portion 18 includes a plurality of pivotally attached links. The links being pivotally attached by pins 21. [0035] The sprocket 14 drives the chain 17 between an extended position with at least a portion of the chain 17 extending from within the body 11, and a retracted position at which at least the majority of the chain 17 is located internally of the body 11. [0036] The mounting member 19 is located at one end extremity of the chain portion 11, while provided at the other end extremity is an abutment 22. The chain portion 11 is located in a generally flat plane, with the abutment 22 extending generally normal relative to that plane. Accordingly the abutment 22 extends generally normal to the chain portion 11. [0037] Captively located with respect to the body 11, and preferably located internally of the body 11 is an abutment engaging member 23. The member 23 includes a body 24 and an abutment portion 25. The body 24 slidably engages portions of the body 11 so as to be slidably guided to move along a generally linear path. However it should be appreciated that the path could also be arcuate. [0038] The member 23 is movable between an abutment engaging position (as shown in Figure 4) positioned to engage the abutment 22, and an abutment non-engaging position (as shown in Figure 5) in a position at which the member 23 will not engage the abutment 22.
    6 [0039] The chain portion 18 follows a path that includes two linear lengths joined by an end "U" portion located adjacent a longitudinal end extremity of the body 11. The path 26 extends generally transverse of the path portion 27. Preferably, the chain portion 18 is located in a flat plane, with the path 26 extending generally parallel thereto. [0040] Preferably, the path along which the chain portion passes, is provided by internal guide surfaces of the body 11. In an alternative preferred form, there could be provided internally of the body 11 a further sprocket that travels with the chain portion 18 and which provides the "U" path portion 27. [0041] The abutment portion 25 has an extension 28 that is located on the other side of the chain portion 11 relative to the body 24, so as to be engageable with a reinforcing surface 29. When the abutment 22 engages the portion 25 and urges the portion 25 in the direction 30 (by operation of the handle 16) the extension 30 engages the surface 29 to aid in supporting the abutment member 23. [0042] In the extended position, the abutment portion 25 is spaced from the internal surface 35 over which the chain portion 17 slides by a gap 36. The chain portion 37 passes through the gap 36 without the abutment 22 being able to when the chain 17 is being moved to the extended position. [0043] It should also be appreciated that when the abutment member 23 is in the non-engaging position, the abutment 22 can move past the abutment member 23 (as shown in Figure 5). However when the abutment member 23 is moved to the abutment engaging position, the abutment 22 engages the portion 25. [0044] Preferably, the abutment engaging member 23 is provided with the locating ball 31 urged by means of a spring 32 to engage recesses. The recess locates the member 23 in the abutment engaging position, while the recess locates the member 23 in the non-engaging position. [0045] In operation of the above described preferred embodiments, when the member 23 is in the non-engaging position, the handle 16 can be operated so that the chain 17 can be moved so that a maximum length of chain 17 can project from within the body 11. The handle 16 can be operated to select the amount of chain 17 to project from within the body 11 between substantially zero and the maximum length. However if the member 23 is moved to the 7 projection engaging position, when the handle 16 is operated to cause the chain 17 to extend outwardly of the body 11, eventually the abutment 22 will engage the portion 25 limiting the maximum length of the chain 17 that may extend outwardly of the body 11. This maximum length will be less than the maximum length when the member 23 is in the non-engaging position. [0046] The position of the member 23 is selected before installation of the winder 10. To provide for operation of the member 23 there is provided in the panel 13 a slot 32 through which a projection 33 of the member 23 projects so that a user may engage the projection 23 and cause sliding movement of the member 23 between the positions thereof. [0047] The body 11 has a plurality of apertures 34 through which threaded fasteners pass to secure the winder 10 to the frame of a window. When securing the winder 10 to the window frame, the panel 13 abuts or is located most adjacent the surface of the window frame to which the winder 10 is being fixed. Accordingly once the winder 10 is installed, the projection 33 is no longer assessable. When installing the winder 10, the chain 17 is in the retracted position. The projection 33 is located at a selected longitudinal end of the slot 33 (defined by the recesses 33 and 34) thereby selecting the maximum length of chain that may project from the body 11. The winder 10 is then fixed to the window frame. [0048] Once the winder 10 is installed, the handle 16 can be operated to cause the chain 17 to project a desired amount from within the body 11, up to the maximum set by selecting the position of the projection 33, that is whether the member 23 in a non-engaging position or an engaging position with respect to the abutment 22.
