Definitions
- the invention is directed to the field of automatic staple guns, and more particularly to a wire guide element for positioning a staple in the gun with respect to a wire or cable to be stapled.
- Staple guns are well known hand-held tools adapted to drive staples into a workpiece.
- Arrow Fastener Company manufactures and sells numerous models of such devices, including the non-powered staple gun sold under the T-50® brand name, and more recently introduced powered models, such as the cordless CT-50TM
- a wire guide for a staple gun, as disclosed for example in U.S. Patent No. 5,884,829, assigned to the Arrow Fastener Company and incorporated herein by reference.
- a wire guide is an element having a surface that fits around a wire or cable, positioning the staple gun so that the staple is driven reliably over the wire or cable to attach it to the work piece. Surfaces on either side of the wire or cable are typically positioned against the surface to be stapled. - ? -
- the safety element is a planar vertically oriented element that protrudes from the bottom of the gun in front of the driver. The planar element actuates a switch, so that the gun can fire only when the safety is fully depressed, i.e. , when the bottom of the gun is positioned against a surface to be stapled.
- Both the LED and safety are advantageously positioned in front of the staple driver, so as not to interfere with the operation of the gun, and especially with the operation of the staple driver.
- To provide a wire guide in combination with these elements poses a technical challenge because the available space in front of the staple driver is limited.
- one object of the invention is to provide a wire guide for a staple gun in a low profile housing at the front end thereof, that can be retracted by the user and which can be combined with other elements, such as an LED and a safety, in a space-saving manner.
- the invention is a wire guide apparatus provided on a staple gun having a staple driver at a front end thereof (such as, without limitation, the CT-50TM model made by Arrow Fastener Corporation).
- a housing for the wire guide is positioned forward of the staple driver.
- the housing houses a cam switch, a cam shaft and a cam, and the cam switch can be moved to rotate the cam.
- a substantially planar wire guide in the housing has a first cutout adapted to be positioned over a wire or cable, and a second cutout adapted to receive the cam.
- the staple gun is provided with a substantially planar safety element having an aperture through which the cam shaft passes, the aperture being elongated so that the safety element can slide in the vertical direction in the housing.
- the housing is provided with a light emitting diode.
- Fig.l is a perspective view of a staple gun incorporating a wire guide apparatus according to the invention.
- Fig. 2 is a detail view of the wire guide housing.
- Fig. 3 is a detail view of the wire guide housing with the wire guide in the extended position.
- Fig. 4 is a detail view of internal elements of the wire guide camming mechanism.
- Fig. 5 is a detail view of internal elements of the wire guide camming mechanism in the extended and locked position.
- the staple gun 10 includes insert 12, located at the front end of the staple gun at the bottom.
- the staple driver sometimes referred to as the "knife” (not shown), is a vertical element located behind the insert that drives the staples out of the gun when the trigger is actuated.
- insert 12 includes a housing 18, which may be provided with slots to guide a wire guide 14 and safety element 22.
- the housing also includes space for cam switch 20.
- the cam switch may be any shape provided that it can be configured to move wire guide 14.
- at least a portion of the cam switch is arcuately shaped, and the cam is seated in a correspondingly shaped arcuate recess in the housing.
- the switch can be circular and seated in a circular recess, as shown in Fig. 2.
- the cam switch is rotatable between a first position and a second position, corresponding to respective first and second positions of wire guide 14, so that the wire guide is either not extended from the bottom of the staple gun, as shown in Fig. 2, or extended from the bottom of the staple gun, and ready to be used.
- This enables convenient use of the staple gun without the wire guide, such as with nails (typically 5/8" nails), or with staples, in a context where it is not desired to staple cable or wire.
- the wire guide is set to a retracted position.
- the housing may have an open back and a central channel on the front of the housing to receive the cam switch 20 and a sub housing 52 holding an LED 50 in a compact low-profile manner.
- "Low profile” in this context means less than 25 mm, preferably less than 20 mm and most preferably less than 15 mm total height of the housing from back to front.
- the wire guide element 14 is preferably planar so that it can be accommodated in a low profile housing.
- the wire guide comprises a first cutout 36 (shown in Fig. 4) with an open end adapted to be positioned over a wire or cable when in use, and a second cutout 32 adapted to receive the cam 28.
- the second cutout has a closed surface 34 (seen in Fig. 4) on one side of the cam which prevents rotation of the cam past surface 34 in either clockwise or counterclockwise directions, while on the opposite side of the cam, the second cutout 32 has room to permit rotation of the cam 28.
- the side of the second cutout opposite the closed side is open, and the cam can be rotated a little more than 180 degrees from the first position to the second position.
- the closed surface 34 of the second cutout may be provided with rounded corners so that the cutout is slightly wider at the closed end than at the open end. This facilitates positioning the bearing surface 30 of the cam in the corners of the second cutout to perform a locking function as described below.
- FIG. 4 The operation of a cam mechanism for a wire guide according to the invention is illustrated in connection with Fig. 4. In Fig. 4, the cam switch has been removed to reveal cam shaft 24, spring 26 and cam 28, which are assembled on back plate 120.
- the cam may have any shape suitable to the purpose, including the ovoid shape shown in the preferred embodiment of Fig. 4.
- bearing surface 30 of the cam 28 is urged against the top surface of the second cutout 32.
- the cam is rotated a little past the longitudinal axis of the wire guide, so that the longitudinal axis of the cam forms a small angle with respect to the longitudinal axis of the wire guide 14, inclining slightly toward the closed side of the second cutout.
- a similar locking functionality is obtained in the second (extended) position of the wire guide, where the cam is rotated a little more than 180 degrees, so that bearing surface 30 of the cam is urged against the bottom surface of the second cutout.
- the wire guide By lodging the bearing surface 30 of the cam in the corner of the cutout, so that the longitudinal axis of the cam is at an angle with respect to a longitudinal axis of the wire guide, the wire guide cannot be moved by applying force in the direction of arrow F, unless the cam is moved again by moving cam switch 20. This is shown best in Fig. 5.
- the locking mechanism is improved by widening the corners of the closed surface 34 in the second cutout, such as by rounding the corners.
- the dimensions of the second cutout are determined by how large a cam is required to make the wire guide protrude from the staple gun by the desired amount in the second position.
- the vertical height of the second cutout may be in a range of about 8.0 mm to about 11.0 mm, and the distance between the top and bottom walls at the closed end, i. e. , at the widest point, may be about 0.1 mm to about 0.5 mm larger than the distance at the opposite, or open, side of the second cutout.
- the first cutout 36 may be formed with prongs 38 defining opposite sides of the first cutout.
- the distance between the two prongs defining the first cutout is not particularly critical, and may be, for example, in a range of about 6.0 mm to about 8.0 mm. In a working embodiment, a width of 7.0 mm was found to be suitable for this purpose.
- the distance from the top of the cutout to the bottom ends of the prongs is not limited. This distance may conveniently be in a range of about 5.0 to 7.0 mm, for example 6.2 mm.
- the top of the cutout may be any shape, such as arcuate shape. In the Figures, the top of the cutout is essentially in the shape of a semicircle.
- the staples ordinarily used with the CT- 50TM made by the Arrow Fastener Company will also be used with a model adapted with the wire guide according to the invention, and the size of the first cutout may be designed accordingly.
- the staple gun may be provided with a safety element 22 which is operatively connected to elements in the body of the gun in a known manner (not shown) so that the gun cannot fire unless the safety is depressed.
- safety 22 is provided with an aperture 44 through which cam shaft passes. The aperture is somewhat elongated, allowing the safety element to move up and down without affecting the wire guide. (Only a portion of aperture 44 is seen in Fig. 4 and Fig. 5, because the view is obscured by the wire guide.) [0027] Fig.
- housing 18 is provided with a central channel which houses the cam switch 20, as well as LED sub housing 52, including LED 50, as well as accommodating the wire guide and cam elements described above. All of these elements can be provided in a low profile format, having a height less than 20 mm, preferably less than 15 mm, which permits the safety 22, the LED 50 and the wire guide 14 all to be positioned in close proximity to the staple driver.
