A HANDLE ASSEMBLY FOR A WINDOW WINDER FIELD

[0001] The present invention relates to handle assemblies, and more particularly but not exclusively to handle assemblies for window winders.

BACKGROUND

[0002] Window winders include a shaft driven sprocket that moves a chain between an extended position and a retracted position, moving a pivotally mounted window panel.

[0003] The sprocket is operated by means of a handle attached to the shaftfixed to the sprocket.

[0004] It is advantageous to have the handle arranged in a folded configuration and an extended operative configuration. In the extended configuration, the handle projects away from the window winder so that it is easily gripped and manipulated by a user.

[0005] A disadvantage of known handles for window winders that are movable between a folded position and an extended position, is that they are difficult to assemble, adding to their cost. A further disadvantage is that they are not reliably retained in the extended position, making them awkward to operate.

OBJECT

[0006] It is the object of the present invention to overcome or substantially ameliorate at least one of the above disadvantages.

SUMMARY OF THE INVENTION

[0007] There is disclosed herein a handle assembly for a window winder assembly, the handle assembly being configured to rotate a shaft about a rotation axis, the assembly including: a base to be attached to the shaft so as to extend outwardly therefrom, the base having a shaft end portion to be attached to the shaft, and a remote end portion to be spaced from the shaft, the remote end portion having a through passage having a major direction of extension generally to said axis; a pivot member pivotally mounted in the passage so as to be retained therein, the pivot member having a through passage that is alignable with the base passage; a handle shaft extending through the pivot member passage and movable relative to the pivot member between a first position and a second position, and relative to the base between a folded position and an operative position; a spring operatively associated with the pivot member and the handle shaft to urge the handle shaft to the first position thereof; and wherein the handle shaft is pivotable relative to said base, by pivoting movement of the pivot member about an axis generally transverse of said base, between the folded position located adjacent the base and the operative position projecting outwardly of the base in a direction generally parallel to said axis when the shaft is in the second position, with the handle shaft retained in the operative position by the handle shaft being in the first position at which the handle shaft engages the remote end portion.

[0008] Preferably, the handle shaft is located in the first position when the handle shaft is located in the folded position, so as to engage the remote end portion to retain the handle shaft in the folded position.

[0009] Preferably, the handle shaft has a head at an end extremity of the handle shaft, with the head engaged in the pivot member when the handle shaft is in the second position to provide for angular movement of the handle shaft between the folded and operative positions thereof, with the head located beyond the pivot member to engage the base when the shaft is in the second position.

[0010] Preferably, the assembly includes a sleeve rotatably mounted on the handle shaft, and secured to the handle shaft so that a user can grip the sleeve to cause movement of the handle shaft between the first and second positions, and the folded and operative positions.

[0011] Preferably, the pivot member is inserted in the remote end portion by movement along the base passage to a socket area at which the pivot member is moved angularly about a transverse axis to be positioned captively located within the remote end portion.

[0012] Preferably, the pivot member when being inserted in the remote end portion, during initial insertion, is moved angularly about said transverse axis.

[0013] Preferably, the remote end portion has at least one slot extending transversely from the base passage, with the pivot member having a projection that moves along the slot to be guided to said socket area.

[0014] Preferably, the handle shaft, when in the folded position, is located adjacent the base.

[0015] Preferably, the handle shaft extends generally parallel to said rotational axis when the shaft handle is in the operative position.

[0016] Preferably, the handle shaft moves angularly about a transverse axis between the folded and operative positions thereof, the transverse axis being transverse relative to the rotation axis.

DESCRIPTION OF EMBODIMENTS

[0038] In the accompanying drawings there is schematically depicted a handle assembly 10 for a window winder. The window winder would have a splined shaft that is rotated about the axis 11 to cause the chain of the window winder to move between an extended position and a retracted position. In Figure 1A and H, the handle assembly 10 is illustrated in a folded position. The operative position of the handle assembly 10 is shown in Figure IC and D, with intermediate configurations illustrated. In this regard it should be appreciated the handle assembly 10, although described with reference to a window winder, is applicable to other hardware structures, such as winders for casement windows.

[0039] The assembly 10 includes a base 12 that is in the form of an arm that would project radially (laterally) from the window winder shaft. That is the base 12 would extend outwardly from the axis 11.

[0040] The base 12 has an end portion 13 and is provided with a splined socket 14. Preferably the shaft of the window winder would be secured in the socket 14 by a threaded fastener.

[0041] The base 12 has a remote end portion 15 provided with a through passage 16. The passage 16 includes a socket area 17 within which a pivot member 18 is received.

[0042] The pivot member 18 has a through passage 19 that is alignable with the passage 16. The pivot member 18 has a pair of laterally extending projections 20 that are guidably received in a pair of guide slots 21 extending laterally from the passage 16. The projections 20 move along the slots 21 so that the pivot member 18 is located in the socket area 17. During this insertion the pivot member 18 is oriented as illustrated in Figure 3A. From the orientation illustrated in Figure 3, the pivot member 18 is inserted and then moved angularly about the axis 22, to provide for further movement along the passage 16. This is illustrated in Figure 3B. Once located in the socket area 17, the pivot member 18 is moved angularly about the transverse axis 22 (provided by the projection 20) so that it is located as illustrated in Figure 3F, G, H and I. In this position the passage 19 of the pivot member 18 is aligned with the passage 16. However the pivot member 18 is now located in the end portion 15.

[0043] Once the passages 16 and 19 are aligned, a shaft 23, with a spring 25 mounted thereon, is inserted through the aligned passages 16 and 19 until a head 24 of the shaft 23 is located internally of the passage 19. With the head 24 located in the passage 19, the spring 25 is compressed. The head 24 is at an end extremity of the shaft 23.

[0044] A handle sleeve 26 is now placed on the shaft 23 and a cap (clip) 27 is engaged with the end extremity of the shaft 23 to retain the sleeve 26 in position mounted on the shaft 23. While the cap 27 is being engaged with the end extremity of the shaft 23, the spring 25 is compressed. However, upon the shaft 23 being released, the cap 27 is moved inwardly of the sleeve 26 as best seen in Figure 31. Once this occurs, the spring expands to the configuration shown in Figure3l, but is still compressed so as to urge the shaft 23 to the position shown in Figure 31.

[0045] Once the cap 27 is located on the shaft 23, the shaft 23 is then prevented from being moved back through the aligned passages 16 and 19 in a removal direction.

[0046] It should be appreciated the sleeve 26 is rotatable about the axis 28 of the shaft 23.

[0047] Once the shaft 23 and sleeve 26 are located in the position shown in Figure 31, the assembly 10 is configured to be operated, that is rotated about the axis 11 to operate the associated window winder.

[0048] The operative position of the handle assembly 10 is best seen with reference to Figure IC, ID and Figure 31. To retain the shaft 23, and therefore the sleeve 26, in the operative position, the pivot member 18 has surfaces 29 and 30 that engage internal surfaces of the end portion 15. The spring 25 urges the head 24 to a position engaging the end portion 15. Once these surfaces are engaged, the shaft 23 and sleeve 26 is retained in a fixed orientation relative to the base 12.

[0049] However, upon the sleeve 26 being gripped and moved in the direction 22 (Figure 1E), the head 24 is moved into the pivot member 18, releasing the pivot member 18 and shaft 23 for angular movement about the axis 22 in the direction 34. The position of the head 24 retracted into the pivot member 18 is shown in Figure 1E, F. The shaft 23 and sleeve 26 can then be pivoted to a position (folded) adjacent the base 12. Upon the sleeve 26 being released, the shaft 23 again moves so that the head 24 leaves the pivot member 18 to again engage with the end portion 15, as shown in Figure 11. This repositioning of the head 24 retains the sleeve 26 in the position (folded) shown in Figure 11, by pressure between the sleeve 26 and surfaces 35 of the base 12.

[0050] In the operative position of the shaft 23 the passages 16 and 19 are aligned. In the folded position of the shaft 23 the passages 16 and 19 are not aligned.

[0051] To pivot the sleeve 26 to the operative position (as shown in Figures IC and ID), the sleeve 26 is again gripped and moved angularly. In respect of moving the sleeve 26 as shown in Figure 1A to Figure IC, the sleeve 26 is merely moved in the direction 33. Gripping the sleeve 26 and moving it radially upwardly is not required as the internal surfaces of the end portion 15 provide for sliding movement of the pivot member 18, and therefore movement of the shaft 23 and head 24 into alignment with passage 16, at which time the spring 25 will cause the head 24 to engage in the passage 16 thereby retaining the sleeve 26 in the operative position.
