Description




BACKGROUND OF THE INVENTION




The present invention relates generally to a screw aligning and guiding device, and more particularly to a screw aligning and guiding device having an arrangement which facilitates loading and unloading of a screw strip into and out of the device.




Numerous screw aligning and guiding devices have heretofore been designed which are adapted to be used with screw strips which have a number of screws supported thereon. The screw aligning and guiding devices are designed to sequentially feed screws into alignment with a bit end of a shaft driven by an electrically powered drill. The screw aligning and guiding devices are also designed to sequentially guide such screws during advancement thereof into a workpiece of such shaft.




In order to sequentially feed screws into alignment with the bit end of the shaft, the previously designed screw aligning and guiding devices have incorporated various pawl and ratchet mechanisms. Such mechanisms operate to engage one of the screws supported on an associated screw strip and urge the screw, and consequently the entire screw strip, upwardly toward a desired position. Typically, the previously designed screw aligning and guiding devices have utilized various springs to generate the biasing force needed to urge the screw strip upwardly.




The pawl and ratchet mechanisms, along with their associated springs, tend to be quite complex arrangements. Further, the interaction of the mechanical parts of the pawl and ratchet mechanism with the screws of the screw strip, make loading and unloading of the screw strip into and out of the device a somewhat difficult and complicated task.




What is needed therefore is a screw aligning and guiding device which overcomes one or more drawbacks of the previously designed devices. For example, what is needed is a screw aligning and guiding device which possesses a mechanism for urging a screw strip upwardly to a desired position in the device which is relatively less mechanically complex. Moreover, for example, what is needed is a screw aligning and guiding device which enables very easy loading and unloading of an associated screw strip into and out of the device.




SUMMARY OF THE INVENTION




In accordance with one embodiment of the present invention, there is provided an apparatus for sequentially aligning a number of screws with a screwdriver and guiding the number of screws during advancement by the screwdriver. The apparatus includes a body which includes (i) a channel adapted to receive a screw strip having the number of screws supported thereon, (ii) a feed passage adapted to sequentially receive the number of screws from the channel, and (ii) a guide track having a planar segment and an inclined ramp segment. The apparatus further includes a movable pawl which travels on the guide track through the planar segment and the inclined ramp segment, wherein (i) the movable pawl contacts at least one of the number of screws when both the movable pawl is located in the planar segment of the guide track and the screw strip having the number of screws supported thereon is located in the channel, and (ii) the movable pawl is spaced apart from all of the number of screws when both the movable pawl is located on the inclined ramp segment of the guide track and the screw strip having the number of screws supported thereon is located in the channel.




Pursuant to another embodiment of the present invention, there is provided a screw driver assembly which includes a shaft having a screw engaging end.

60


by the fastener


56


.

FIG. 10

shows a cross-sectional view of the components of the slider assembly


52


cooperating with one of the rails


30


.




During operation of the device


10


, the finger


62


is urged upwardly by the spring bias of the spring


50


. As a result, the finger


62


contacts one of the screws


16


and urges such screw


16


, and consequently, the entire screw strip


15


and all of the other screws


16


supported thereon upwardly until the uppermost screw


16


is positioned within the feed passage


24


,


36


as shown in

FIG. 2

Thereafter, the drill


46


is operated to rotate the uppermost screw


16


. Rotation of the uppermost screw


16


causes such screw to separate from the screw strip


15


in a conventional manner. Then, advancement of shaft


44


causes advancement of such screw


16


whereby the structure of the device


10


which defines the feed passage


24


,


36


guides the screw


16


during its advancement within the device


10


. Thereafter, continued rotation of the screw


16


by the shaft


44


causes the screw


16


to be advanced into a workpiece such as a piece of wood.




After the uppermost screw


16


is advanced into the workpiece and the shaft


44


is retracted out of the feed passage


24


,


36


, the next uppermost screw


16


is advanced into the feed passage


24


,


36


in a similar manner. Once the spring


50


retracts substantially completely into the spring recess


54


such that slider assembly


52


is moved to its uppermost position, the slide pawl must be cocked or otherwise manually pulled downwardly to again generate spring bias to urge the screw strip


15


and the screws


16


supported thereon in an upward direction.




In order to prevent the screw strip


15


and the associated screws


16


from being pulled downwardly while the movable pawl is being cocked downwardly, the device


10


further includes a stationary pawl


64


, The stationary pawl


64


includes an end portion which extends into the strip and screw channel


22


,


35


so that such end portion contacts one screw


16


supported on the strip


15


as the movable pawl is being cocked downwardly thereby preventing further downward travel of the screw strip


15


and the associated screws


16


.

FIG. 4

shows the screw


16


which is positioned next to the uppermost screw


16


contacting the stationary pawl


64


.




The stationary pawl


64


is secured to the second housing portion


12


by a fastener


66


. A pair of guards


67


are positioned adjacent to the stationary pawl


64


as shown in

FIGS. 3 and 5

to provide protection to the stationary pawl


64


from inadvertent contact.




The guide track


28


includes a planar segment


68


and an inclined ramp segment


70


as shown in FIG.


11


. In particular, the rails


30


extend for a first distance in a substantially planar manner from a point A to a point B. Then, the rails


30


extend in an inclined ramp-like manner from the point B to a point C. To this end, the first housing portion


11


includes a ramp member


72


defined therein as shown in FIG.


11


.




When both the movable pawl


48


is located on the planar segment of the guide track


28


and the screw strip


15


having the number of screws


16


supported thereon is located in the strip and screw channel


22


,


35


, the movable pawl


48


contacts at least one of the number of screws


16


so as to urge the screw strip


15


and associated screws


16


upwardly. In particular, when both the movable pawl


48


is located on the planar segment of the guide track


28


and the screw strip


15


having the number of screws


16


supported thereon is located in the strip and screw channel


22


,


35


, the finger


62


of the movable pawl


48


is urged into contact with a lower side of a corresponding screw


16


as shown in

FIG. 2

so as to urge the entire screw strip


15


and associated screws


16


upwardly.




After all of the screws


16


associated with one screw strip


15


are utilized, and it is desired to load a new screw strip


15


having associated screws


16


supported thereon into the device


10


, a user grasps the handle


58


of the movable pawl


48


and urges it downwardly against the spring bias of the spring


50


from its actual position shown in solid lines in

FIG. 1

to a loading position shown in phantom in FIG.


1


. This action causes the slider assembly


52


to be advanced in sliding contact with the rails


30


to the loading position shown in phantom in FIG.


1


. Now with the slider assembly


52


positioned in such loading position, the new screw strip


15


with its associated screws


16


is advanced upwardly into the strip and screw channel


22


,


35


until its upper most screw is positioned in the feed passage


24


,


36


.




When the movable pawl


48


is located on the inclined ramp segment


70


of the guide track


28


and the screw strip


15


having the number of screws


16


supported thereon is located in the strip and screw channel


22


,


35


, the movable pawl


48


is spaced apart from all of the number of associated screws


16


. In particular, when both the movable pawl


48


is located on the inclined ramp segment


70


of the guide track


28


and the screw strip


15


having the number of screws


16


supported thereon is located in the strip and screw channel


22


,


35


, the finger


62


of the movable pawl


48


is spaced apart from all of the number of associated screws


16


. Moreover, when the movable pawl


48


is located at this orientation relative to the first housing portion


11


, the movable pawl


48


(including its finger


62


) is located at a vertical position which is interposed between the upper end


18


of the screw strip


15


and the lower end


20


of the screw strip


15


.




Thereafter, once the new strip


15


and associated screws


16


are loaded into the strip and screw channel


22


,


35


, the movable pawl


48


is released thereby allowing the slider assembly


52


to be urged upwardly by the spring bias of spring


50


until the finger


52


contact one of the screws


16


to urge the entire strip


15


and its associated screws


16


upwardly.




If it is desired to remove a partially full screw strip from the device


10


(i.e. a screw strip


15


from which a number of screws have been removed, yet some are still remaining on the screw strip), the present invention facilitates such removal. In particular, in order to remove such partially full screw strip, the handle


58


is advanced onto the inclined ramp segment


70


to a location as shown in phantom in

FIGS. 7 and 8

. Thereafter, with the handle


58


located on the inclined ramp segment


70


, the user grasps an end portion of the stationary pawl


64


which is extending out of the body


13


as shown in FIG.


5


and pulls the stationary pawl


64


in a direction indicated by arrow D. Pulling the stationary pawl


64


in such a direction moves the stationary pawl


64


out of the strip and screw channel


22


,


35


so as to allow the strip


15


along with the associated screws


16


to be freely advanced downwardly out through the entrance opening


19


of the body


13


.
