Abstract
Description
- The present invention relates to a wire retracting device of a window regulator which moves the window pane to a desired position by moving a wire or wires, and more particularly to a wire retracting device which is powered by an electric motor.
- Hitherto, there have been proposed various kinds of wire retracting devices for a motor-powered window regulator. As will be described in detail hereinafter, an exemplified motor-powered window regulator comprises generally a window pane carrier movable together with the window pane, two wires extending from the carrier, a wire retracting device to which the wires lead, and a motor-powered drive unit for driving the wire retracting device. Upon electric energization of the drive unit, the power created by the motor drives the wire retracting device to retract either one of the wires thereby moving the window pane carrier. Upon deenergization of the electric drive unit, the movement of the carrier stops and thus the window pane stops at a desired position. Some of the wire retracting devices employed in the above-mentioned window regulator are of a type which is equipped with a so-called "automatic wire slack remover" which automatically removes the slackness of the wires. Usually, the remover comprises two wire retracting drums (viz., drive and driven drums) which are coaxially and rotatably disposed about a common supporting shaft and mated with each other through ratchet means formed therebetween. However, due to insufficient supporting function of the supporting shaft employed therein, some of such wire retracting devices tend to induce unstable rotation of the two drums particularly after long use thereof. Of course, such undesirable rotation of the drums brings about unbalanced operation of the wire retracting device.
- It is therefore an essential object of the present invention to provide an improved wire retracting device which is free of the above-mentioned drawback.
- According to the present invention, there is provided, in a motor-powered window regulator having a motor-powered drive unit with an output shaft, a wire retracting device which comprises a casing, a supporting shaft disposed in the casing with its axial one end supported by a bearing fixed to the casing, a wire winding annular device concentrically and rotatably disposed on the supporting shaft and winding thereon a wire which extends to a window pane mover, and supporting means for rotatably supporting the axial other end of the supporting shaft to an axial end portion of the output shaft of the drive unit.
- Other objects and advantages of the present invention will be apparent from the following description when taken in conjunction with the accompanying drawings, in which:
- Fig. 1 is a sectional view of a less preferred embodiment of a wire retracting device employed in a motor-powered window regulator;
- Fig. 2 is an entire view of a motor-powered window regulator which incorporates therein an improved wire retracting device according to the present invention;
- Fig. 3 is a sectional view of the improved wire retracting device of the invention, which is taken along the line III-III of Fig. 2;
- Fig. 4 is an exploded view of the improved wire retracting device of the invention; and
- Fig. 5 is a perspective view of a motor-powered drive unit which is incorporated with the improved wire retracting device of the invention.
- Prior to describing in detail the construction of the improved wire retracting device of the invention, the entire system of a motor-powered window regulator in which the wire retracting device is employed will be described with reference to Fig. 2.
- Referring to Fig. 2, there is shown the motor-powered window regulator which is designed to move up or down an automotive door window to a desired position by the force of an electric motor. The window regulator comprises an
elongate plate 10 which is disposed in an automotive door (not shown) to extend vertically. Theelongate plate 10 is formed at its one side with aguide rail 12 which extends therealong. Slidably moved along therail 12 is a carrier plate 14 which has a grooved portion (not shown) for slidably receiving therein therail 12. Awindow pane 16 is mounted on and secured to the carrier plate 14 and thus they are moved together. It is thus to be noted that thewindow pane 16 as illustrated in the drawing assumes its lowermost position thereby fully opening the door window. Designated bynumeral 18 is a wire retracting device of the invention which is mounted on abase plate 20 secured to an inner panel (not shown) of the door. Thewire retracting device 18 is positioned at the outboard side with respect to the door inner panel. Extending from thedevice 18 are twoflexible wires wire 22 is fixed to the carrier plate 14 after passing over aguide roller 26 arranged at the upper portion of theelongate plate 10, while, the leading end 24a of theother wire 24 is also fixed to the carrier plate 14 after passing through aguide groove 28 arranged at the upper portion of theelongate plate 10 and then passing through a turning groove 30 formed at the lower portion of theelongate plate 10. On the inboard side of thebase plate 20, there is mounted a motor-powered drive unit (see Fig. 5) which comprises anelectric motor 32 and aspeed reduction gear 34. As will be described in detail hereinafter, the output shaft of thespeed reduction gear 34 is detachably connected to thewire retracting device 18 to drive the same. - When, in operation, the
electric motor 32 is energized to run in one direction, thewire retracting device 18 retracts one of the wires, for example, thewire 22 while drawing out theother wire 24 therefrom. With this, the carrier plate 14 and thus thewindow pane 16 mounted thereon are moved together upward along therail 12 until the electric supply to themotor 32 stops. Upon this stop of electric supply, the movement of thewindow pane 16 stops, and thereafter, thewindow pane 16 keeps its half-open position irrespective of its weight. When, on the contrary, theelectric motor 32 is energized to run in the reversed direction, thewire retracting device 18 retracts thewire 24 while drawing out thewire 22 therefrom. With this, thewindow pane 16 is moved downward until the electric supply to themotor 32 stops. - In the following, the construction of the
wire retracting device 18 will be described in detail with reference to Figs. 2 to 5, particularly Figs. 3 and 4. - As will be best seen from Fig. 4, the
wire retracting device 18 comprises acasing 36 which has three lug portions 36a, 36b and 36c each extending radially outwardly from the open side of thecasing 36. Thecasing 36 is bolted at the lug portions 36a, 36b and 36c to thebase plate 20 which has an opening 20a, as shown in Fig. 3. Thecasing 36 is formed at the bottom portion thereof with an opening 38 into which a reduced end portion 40a of abearing 40 is securedly fixed. Thebearing 40 has a recess consisting of an axially extending cylindrical section 40b and a rectangular section 40c. The diameter of the cylindrical section 40b is greater than the thickness of the rectangular section 40c. - A
drum shaft 42 having upper and lower pin portions 42a and 42b is beared by thebearing 40 in such a manner that the lower pin portion 42b is rotatably received in the cylindrical section 40b of thebearing 40. Aspiral spring 44 having inner and outer ends 44a and 44b is disposed about the fixed bearing 40 (see Fig. 3) with the inner end 44a hooked to the rectangular section 40c of the recess of thebearing 40. - Designated by
numeral 46 is a driven drum which has at its lower portion a circular recess into which thespiral spring 44 is received (see Fig. 3). The cylindrical outer wall of the drivendrum 46 is formed with a helical guide groove 46a, and the circular upper portion of the same is formed at the periphery thereof with ratchet teeth 46b and at the center thereof with a rimmed hole 46c. The rimmed hole 46c extends to the above-mentioned circular recess of the drivendrum 46. The outer end 44b of the spiral spring is hooked to a suitable portion of. the circular recess of the drivendrum 46 so that thedrum 46 is biased to rotate in a wire retracting direction, that is, in the counterclockwise direction in Fig. 4. As is seen from Fig. 3, thedrum shaft .42 is received in the rimmed hole 46c of the drivendrum 46 and projected upwardly considerably from the same. - As is understood from Fig. 3, a
drive drum 48 is coaxially arranged on the drivendrum 46 with its upper surface slidably contacting with the inner surface of thebase plate 20. Thedrive drum 48 has acenter bore 50 consisting of a smaller diameter section, an intermediate section and a larger diameter section. Similar to the drivendrum 46, the cylindrical outer wall of thedrive drum 48 is formed with a helical guide groove 48a, and the circular lower portion of the same is formed at the periphery thereof with ratchet teeth 48b. Thedrive drum 48 is arranged on the drivendrum 46 in such a manner that the smaller diameter section, the intermediate section and the larger diameter section of the center bore 50 receive therein respectively the upper pin portion 42a of thedrum shaft 42, the major portion 42c of the same and the bored rim portion 46c of the drivendrum 46, as is understood from Fig. 3. It is to be noted that the upper pin portion 42a of thedrum shaft 42 is projected outwardly from the center bore 50 of thedrive drum 48. Upon proper mounting of thedrive drum 48 on the drivendrum 46, the ratchet teeth 48b of thedrive drum 48 are operatively mated with the ratchet teeth 46b of the drivendrum 46. For assuring this ratchet engagement between the ratchet teeth 48b and 46b, awave washer 52 is disposed between the bottom portion of thecasing 36 and the drivendrum 46, by which the drivendrum 46 is biased toward thedrive drum 48. The ratchet teeth 48b and 46b are so designed as to couple these twodrums drive drum 48 is rotated in the counterclockwise direction (in Fig. 4) or the drivendrum 46 is rotated in the clockwise direction (in Fig. 4). Thus, relative rotation between them is permitted only when thedrive drum 48 is rotated in the clockwise direction or the drivendrum 46 is rotated in the counterclockwise direction. Theflexible wires drums wire 22 is hooked to a cut 46d formed in the drivendrum 46, while, the end 24b of theother wire 24 is hooked to a cut (not shown) formed in thedrive drum 48, so that thewire 22 is retracted by the drivendrum 46 when the latter 46 is rotated in the counterclockwise direction in Fig. 4, while, thewire 24 is retracted by thedrive drum 48 when the latter 48 is rotated in the clockwise direction. It is thus to be noted that pull-out movement of thewire 22 induces the coupled rotation of the driven and drivedrums other wire 24 to be retracted by thedrive drum 48, while, the pull-out movement of thewire 24 induces the coupled rotation of thedrums wire 22 to be retracted by the drivendrum 46. In order to provide simultaneous and equivalent movement between thesewires drums - The
drive drum 48 is formed with an annular recess 54 about thecenter bore 50. The recess 54 is formed at its bottom portion with a coupling recess which consists of three equally spaced rectangular depressions 56a, 56b and 56c and three equally spaced arcuate thin grooves (no numerals) through which the depressions are merged with one another. Thedrive drum 48 is further formed at the peripheral portion with six depressions 58 (only one is numbered) for the purpose of reducing the weight thereof. - A generally triangular bush 60 of rubber material is intimately fitted in the coupling recess of the
drive drum 48. For this, the bush 60 has an external shape matching with the shape of the coupling recess. The bush 60 has thus equally spaced threelug portions 60a, 60b and 60c each having therein a deformable recess (no numeral), as is seen from Fig. 4. As will become clear from the following description, the deformable recesses of thelug portions 60a, 60b and 60c of the bush 60 catch three projections 62a, 62b and 62c formed on the after-mentioned output shaft of thespeed reduction gear 34. - Referring to Fig. 5, there is shown the motor-powered drive unit comprising the
electric motor 32 and thespeed reduction gear 34. As is seen from this drawing, the three projections 62a, 62b and 62c are provided on acircular plate 62 which is coaxially connected to an output shaft 64 (see Fig. 3) of thespeed reduction gear 34. Thecircular plate 62 is formed at its center with a bore 66 which has a size matching with the upper pin portion 42a of thedrum shaft 42. The drive unit has several bored lug portions 68 (only one is numbered) which are bolted to thebase plate 20. - As is seen from Fig. 3, upon assembly, the three projections 62a, 62b and 62c of the
output shaft 64 of the drive unit are respectively caught by the deformable recesses of the bush 60 fitted in thedrive drum 48. It is now to be noted that under this coupling condition, the outwardly projected upper pin portion 42a of thedrum shaft 42 is neatly received in the bore 66 of thecircular plate 62. With this coupling, the driving force produced by themotor 32 can be transmitted to thewire retracting device 18 for moving the window pane upward or downward in the following manner. - For ease with which the description of the operation is made, the description will be commenced with respect to the condition as shown in Fig. 2 wherein the
window pane 16 assumes its lowermost position (viz., the window is fully open). - When the
motor 32 is energized to run in a direction to rotate thedrive drum 48 in the counterclockwise direction in Fig. 4, the drivendrum 46 is rotated together thereby winding thereon thewire 22 while drawing out theother wire 24 from thedrive drum 48. With this motion, thewindow pane 16 is moved upward together with the carrier plate 14. When, now, themotor 32 is deenergized, the movement of thewindow pane 16 stops and thereafter, thewindow pane 16 keeps the stopped position irrespective of the weight of thewindow pane 16. This is because of the inherency of theoutput shaft 64 of thespeed reduction gear 34, that is, the unmovableness of theoutput shaft 64 under such condition. When, then, themotor 32 is energized to run in the reversed direction to rotate thedrive drum 48 in the clockwise direction in Fig. 4, thedrive drum 48 winds thereon thewire 24 while pulling and thus drawing theother wire 22 from the drivendrum 46. With this movement, thewindow pane 16 lowers. Of course, this downward movement stops upon deenergization of themotor 32. - When the
wire 22 becomes slackened during the operation for some reasons, the drivendrum 46 is rotated slightly in the wire retracting direction (viz., in the counterclockwise direction in Fig. 4) relative to thedrive drum 48 by the biasing force of thespiral spring 44. Thus, the slackness of thewire 22 disappears. When, now, theother wire 24 becomes slackened, the carrier plate 14 and thus thewindow pane 16 are both moved upwardly but slightly because of the biasing force of thespiral spring 44 constantly applied to drivendrum 46 to rotate in the wire retracting direction. Thus, the slackness of thewire 24 is removed. - In the following, advantageous features of the present invention will be described.
- (1) Because the axial ends 42b and 42a of the
drum shaft 42 are both stably supported by the fixedbearing 40 and the output shaft 64 (or 62) of the drive unit fixed to thebase plate 20, the rotation of the drive and drivendrums drum shaft 42 is supported by only the fixedbearing 40. Experiment has revealed that such device tends to induce unstable rotation of the drive and driven drums particularly after long use thereof due to insufficient supporting of thedrum shaft 42. - (2) Upon assembly of drive unit to the
wire retracting device 18, the outwardly projected pin portion 42a of thedrum shaft 42 serves as a guide means for positioning theoutput shaft 64 of the drive unit. Thus, the assembly work is facilitated considerably.
