Abstract
Description
- The present invention relates generally to tools for use in dispensing plastic fasteners and more particularly to needles which are used in such tools.
- Plastic fasteners are widely used in commerce to attach tags or other items to articles in a manner which minimizes the risk of inadvertent detachment therefrom. One type of plastic fastener is manufactured in the form of fastener stock comprising a pair of continuously connected, elongated side members which are interconnected by a plurality of thin transverse cross links. Typically, one side member comprises a plurality of end-bars or T-bars joined together by severable connectors. The fastener stock is usually produced by molding or stamping from flexible plastic materials, such as nylon, polyethylene, and polypropylene. Additional information pertaining to fastener stock may be obtained from the following commonly assigned U.S. patents, all of which are incorporated herein by reference: U.S. Pat. No. 4,955,475, issued September 11, 1990; U.S. Pat. No. 4,456,161, issued June 26, 1984; U.S. Pat. No. 4,121,487, issued October 24, 1978; and U.S. Pat. No. 3,103,666, issued September 17, 1963.
- The above-described fastener stock is typically loaded into a dispensing tool, often referred to as a "tagger gun." A tagger gun normally includes a hollow needle having a longitudinal slot extending over its length. The fastener stock is inserted into the tagger gun behind the needle. Upon actuation of a trigger mechanism in the gun, an individual fastener is separated from the fastener stock and is inserted into the desired article of commerce through the needle.
- In U.S. Pat. No. 4,273,279, which is incorporated herein by reference, a typical needle having a single part construction is described. The needle includes a shank or "stem" portion which has a relatively sharp tip to permit penetration into the article to be attached and an integrally formed substantially cylindrical base portion. The shank portion is hollow to permit the T-bar end of the fastener to pass therethrough and has a longitudinal slot to permit the filament of the fastener to extend therefrom as the T-bar end moves through the needle. The base portion includes a central bore with an inner diameter equal to the inner diamter of the hollow shank. The base portion also has a longitudinal slot aligned with the slot in the shank. The needle is made by machining the shank portion and the base portion from a single piece of metal. As can readily be appreciated, however, machining metal into a desired shape can be a rather arduous and time-consuming task which allows little margin for error.
- Also disclosed in U.S. Pat. No. 4,273,279 is a needle assembly having a conventional two part structure. The needle assembly includes a shank portion stamped from a piece of a steel and a base portion which is formed of plastic and is molded around the shank portion. One disadvantage with this type of needle, however, is that the molding process is rather expensive, accounting for an overwhelming percentage of the total cost of manufacturing the needles.
- Because needles used in tagger guns tend to break frequently and require replacement, they are typically removably mounted in an opening formed in the front end or "nose" of the tagger gun and are releasably secured therein by means of a locking mechanism in the tagger gun.
- For example, as shown in Figs. 21 and 22 of U.S. Pat. No. 4,456,161, the needle locking mechanism includes a locking pin, which engages a corresponding recessed area formed in the needle. The locking pin is also provided with a cut-out slot which provides a passageway for insertion and removal of the needle. The locking pin is biased in its locking position by means of a spring mounted in the tagger gun. When the locking pin is pushed towards the spring to compress it, the slot on the locking pin aligns with the needle to free it for removal. Preferably, that portion of the locking pin engaging the recessed area of the needle in locking position is rectangular or square in cross-section.
- Unfortunately, the above-described needle locking mechanism suffers from certain disadvantages. For example, the needle may be inserted into the opening in the tagger gun in any one of an infinite number of angular orientations. An inherent problem with this mounting procedure is that it is not intuitively obvious or readily apparent as to what angular orientation is correct. If the angular orientation of the needle is incorrect, the locking pin will not properly engage the recessed area in the needle, frequently resulting in needle breakage or in the jamming of the needle in the tagger gun, or in an ineffective locking of the needle. Moreover, one or more components of the locking mechanism may break or require replacement after repeated or prolonged use.
- Another patent of interest to the present invention is the commonly assigned U.S. Pat. No. 4,998,661, issued March 12, 1991 and incorporated herein by reference. In this patent, a needle assembly adapted for removable mounting on the front end of a tagger gun is disclosed. The needle assembly comprises a needle encased in a holder which may be easily secured to and removed from the front end of the tool, the holder defining in conjunction with the remainder of the tool at least a major portion of the feed track. In a preferred construction of the needle assembly, the needle is a hollow slotted metal structure and the holder is comprised of plastic which is injection molded around the needle.
- In U.S. Patent No. 4,877,172 there is described and illustrated in Fig. 4 the use of a tapered needle locking screw for locking an inserted needle in place. Although the needle locking screw provides a secure, snug engagement of an inserted needle, it still requires precise alignment of the needle before locking.
- It is an object of the present invention to provide a new and improved needle for use as part of a tool for dispensing plastic fasteners.
- It is another object of the present invention to provide a needle as described above which can be removably mounted in the nose of a fastener dispensing tool and releasably secured in place.
- It is yet another object of the present invention to provide a needle as described above which does not require an extraneous needle locking mechanism for releasably securing the needle in the nose of the fastener dispensing tool and, therefore, can be more easily inserted into and removed from the nose of the fastener dispensing tool.
- It is still another object of the present invention to provide a needle as described above which can be made by a more economical manufacturing process than is typically available for existing needles.
- In accordance with the objects of the present invention as broadly recited above, a needle for use as part of a fastener dispensing tool comprises an elongated member having a stem portion and a base portion, the stem portion being generally cylindrically shaped and terminating in a sharp tip at its front end, the base portion being sized and shaped for insertion into the nose of the fastener dispensing tool, the base portion having a spring tab for releasably securing the base portion within the nose of the fastener dispensing tool and a generally cylindrically shaped bottom section, the needle having a longitudinally extending slot extending through said stem portion and said bottom section of said base portion.
- Preferably, the base portion and the stem portion of the needle are made from a single sheet of metal by a stamping and/or rolling technique. In addition, the base portion of the needle is preferably shaped to include a second spring tab. A first portion of one of the spring tabs is sized and shaped to releasably engage a recessed area formed in the nose so as both to prevent unintended removal of the base portion therefrom and to limit rearward insertion of the base portion into the nose. A second portion of the same tab is sized and shaped to engage another portion of the nose so as to prevent vertical movement of the base portion therewithin. The other spring tab serves as a registration member to align the base portion in its desired longitudinal, vertical and angular orientations.
- Additional objects, as well as features and advantages, of the present invention will be set forth in part in the description which follows, and in part will be obvious from the description or may be learned by practice of the invention. In the description, reference is made to the accompanying drawings which forms a part thereof and in which is shown by way of illustration specific embodiments for practicing the invention.

- Referring now to the drawings and more particularly to Figs. 1 through 4, there is shown one embodiment of a needle for use as part of a tool for dispensing plastic fasteners, the needle being constructed according to the teachings of the present invention and represented generally by reference numeral 11.
- Needle 11, which is preferably made by stamping and/or rolling a single sheet of metal, comprises an elongated, hollow, cylindrically shaped
stem portion 13.Stem portion 13 terminates at its forward end with a relativelysharp tip 15 and is provided with alongitudinally extending slot 17. The inner diameter ofstem portion 13 is somewhat larger than the outer diameter of the T-bar end of a plastic fastener (not shown) to be dispensed through needle 11. The width ofslot 17 is sufficiently large to accommodate the cross-link portion of the fastener to be dispensed through the needle. - Needle 11 also includes a
base portion 19.Base portion 19 includes a cylindrically shapedbottom section 21 which has an inner diameter substantially equal to the inner diameter ofstem portion 13 and is aligned therewith. A longitudinally extendingslot 23 is formed inbottom section 21 and is aligned withslot 17 ofstem portion 13 so as to permit the cross-link of the fastener being dispensed by the tool to extend from the T-bar end as the latter is pushed through the needle.Base portion 19 also includes a pair ofspring tabs slot 23. - As will hereinafter be discussed in greater detail,
base portion 19 of needle 11 is sized and shaped for insertion into anopening 31 formed at the front end ornose 33 of a tagger gun, see Figs. 5 and 6. When being assembled,base portion 19 of needle 11 is inserted into opening 31 fromfront 34 offront end 33. Whenbase portion 19 is inserted intoopening 31,spring tabs inner walls opening 31.Tab 24 includes afirst portion 25 and asecond portion 26.First portion 25 is shaped to fit into a recessed area of opening 31 in such a way as to prevent the unintended removal ofbase portion 19 from opening 31. In addition, when mounted in place, the top offirst portion 25 oftab 24 extends up above opening 31 in such a way as to permit a user to grasp it and to push it inwardly out of engagement with the recessed area so thatbase portion 19 may be removed from opening 31.Second portion 26 oftab 24 is shaped and located relative tofirst portion 25 so as to abut another portion of opening 31 in such a way as to minimize vertical movement ofbase portion 19 withinopening 31.Tab 27 serves as a registration member which helps to keep the needle in its desired longitudinal, vertical and axial orientation when mounted on the tagger gun. - Preferably, needle 11 is made of a metal of the type typically used in tagger gun needles. Examples of suitable metals for needle 11 are a beryllium/copper alloy, stainless steel, and plated or coated steel. As can readily be appreciated, one advantage to the construction of the needle of the present invention is that the needle can be manufactured in its entirety by a stamping and/or roll forming process. Such a process is considerably less expensive and time-intensive than the machining process or the combination stamping/molding process described above in connection with the manufacture of conventional needles.
- As can be seen in Figs. 5 and 6, opening 31 in
front end 33 is of a general slot type configuration extending in fromfront 34 ofnose 33 and down from the top 34-2 ofnose 33.Opening 31 is defined by acurved bottom wall 35 and a pair of upwardly extendingside walls Bottom wall 35 is shaped to receivebottom section 21 ofbase 19.Side walls tabs -
Side wall 37 includes an inwardly taperingfront portion 40 and a rearwardly disposed, generally rectangularly shaped, recessedarea 41.Front portion 40 includes anotch 42, which is sized and shaped to receivesecond portion 26 oftab 24.Notch 42 is defined in part by a top surface 42-1, which serves to limit vertical movement ofsecond portion 26 oftab 24 whenbase portion 19 is inserted into opening 31 (see Fig. 8).Area 41 is defined by a rear surface 41r, a side surface 41s, and afront surface 41f.Area 41 is appropriately dimensioned so that, whenfirst portion 25 oftab 24 is inserted thereinto (i.e., whenbase portion 19 is fully inserted into opening 31), longitudinal movement ofbase portion 19 withinopening 31 is prevented. -
Side wall 39 includes anotch 43, which is sized and shaped to recievetab 27.Notch 43 is defined in part by a top surface 43-1, which serves to limit upward movement oftab 27, and a rear surface 43-2, which serves to limit insertion ofbase portion 19 intoopening 31. -
Walls base portion 19 by engagingtabs - The front end of opening 31 (which spans from the
front surface 40f ofportion 40 across notch 43) is approximately the same width as the rear end of needle 11 in its relaxed position. Consequently, a user may mount needle 11 in opening 31 simply by aligning the rear end of needle 11 with the front end of opening 31 and then sliding needle 11 intoopening 31 untilfirst portion 25 ofspring tab 24 locks into place inarea 41. There is no need to pushtab 24 inwardly before pushingbase portion 19 throughopening 31. Thus, installation of needle 11 intool 31 can be achieved in one motion and, assuming thatnose 33 is kept stationary, can be accomplished using only one hand. - Referring now to Figs. 7 through 9, there are shown top, front and side fragmentary views, respectively, of needle 11 fully inserted into
opening 31. As can be seen in Fig. 9, the top offirst portion 25 oftab 24 extends a short distance out of the top of opening 31 to permit it to be manipulated by a user, for instance, in removing needle 11 from the tool. This may be done, as seen in Fig. 7, by pushingfirst portion 25 towards surface 43 (in the direction of arrow A) until it has clearedsurface 41f and then pushing (or pulling) base portion through the front ofopening 31. - Referring now to Fig. 10, there is shown a section view of needle 11 mounted in
opening 31. As can be seen, that portion of needle 11 that is mounted withinopening 31, i.e.,base portion 19, has an outer diameter d and a length l. It is believed that the ratio of diameter to length (d/l) is indicative of the relative strength of needle retention as well as the strength and durability of the tool, with smaller ratios indicating greater strength and greater ratios indicating lesser strength. Comparing the d/l ratio of needle 11 to that for conventional needles of the type described in U.S. Pat. No. 4,273,279, one finds needle 11 to have a smaller d/l ratio since the lengths of the respective base portions are substantially equal whereas the diameter of the base portion of needle 11 is considerably smaller than the diameter of the base portion of conventional needles. Consequently, it is believed that needle 11 is more fully retained and, therefore, more likely to remain in proper alignment than conventional needles of the type described above. - Referring now to Fig. 11, there is shown a second embodiment of a needle for use as part of a fastener dispensing tool, the needle being constructed according to the teachings of the present invention and being represented generally by reference numeral 71.
- Needle 71, which, like needle 11, is preferably made by stamping and/or rolling a sheet of metal, such as a beryllium/copper alloy, comprises a slotted, hollow, cylindrically-shaped
stem portion 73 substantially identical to stemportion 13 of needle 11. Needle 71 also includes abase portion 75, which includes a slotted cylindrically shapedbottom section 77, which has an inner diameter substantially equal to the inner diameter ofstem portion 73 and which is aligned therewith. In addition,base portion 75 includes a generally upwardly extendingremoval tab 79 and a generally laterally extendingwing 81. As can be seen,wing 81 is split to include aspring tab 83, which functions to releasablysecure base portion 75 within a suitably shaped slot formed in the nose of a fastener dispensing tool. (See, for example, Fig. 12 which illustrates a generally T-shapedslot 85 formed in the nose of afastener dispensing tool 87. Depression ofspring tab 83 withinslot 85 for purposes of removing needle 71 fromtool 87 may be achieved by pushing downwardly on arelease button 89 integrally formed ontagger gun 87.) - Referring now to Fig. 13, there is shown a third embodiment of a needle for use as part of a fastener dispensing tool, the needle being constructed according to the teachings of the present invention and being represented generally by
reference numeral 101. -
Needle 101 is substantially identical in construction and composition to needle 71, the only difference between needle 71 andneedle 101 being thatneedle 101 does not include aremoval tab 79. Like needle 71,needle 101 may be releasably secured withinslot 85 of tool 87 (see Fig. 12). - Referring now to Figs. 14 and 15, there is shown a fourth embodiment of a needle for use as part of a fastener dispensing tool, the needle being represented generally by
reference numeral 151. - In contrast with needle 11, which is primarily intended for use with tagger guns of the type wherein a T-bar of a fastener is loaded into the rear end of the needle through the longitudinal slot thereof,
needle 151 is intended primarily for use with, but is not limited to use with, tagger guns of the type wherein the T-bar of a fastener is loaded into the rear end of the needle from a direction generally perpendicular to the longitudinal slot of the needle. An example of a tagger gun having such a loading mechanism is sold by Dennison Manufacturing Co. under the trademark MARK II PISTOL-GRIP SWIFTACHER TOOL. -
Needle 151, which may be made from the same materials used to make needle 11, is preferably made by stamping and/or rolling a single sheet of metal. As can be seen,needle 151 comprises an elongated, hollow, cylindrically shapedstem portion 153.Stem portion 153 terminates at its forward end with a relativelysharp tip 155 and is provided with alongitudinally extending slot 157. The inner diameter ofstem portion 153 is somewhat larger than the outer diameter of the T-bar end of a plastic fastener (not shown) to be dispensed throughneedle 151. The width ofslot 157 is sufficiently large to accommodate the cross-link portion of the fastener to be dispensed through the needle. - Needle 11 also includes a
base portion 159.Base portion 159 includes abottom section 161 which is shaped to define alongitudinally extending slot 163.Slot 163 is aligned withslot 157 ofstem portion 153 so as to permit the cross-link of the fastener being dispensed by the tool to extend from the T-bar as the latter is pushed through the needle. The front portion ofbottom section 161 is generally cylindrical in shape and has an inner diameter substantially equal to the inner diameter ofstem portion 153. The rear portion ofbottom section 161 is shaped to define a V-shapedcutting element 162, which may be used to sever an individual fastener from fastener stock. -
Base portion 159 also includes a pair ofspring tabs slot 163 and are bent outwardly away from each other.Tab 165 includes afirst portion 166 and asecond portion 168.First portion 166 andsecond portion 168 perform substantially the same functions asfirst portion 25 andsecond portion 26 oftab 24, respectively.Tab 167, in addition to performing substanially the same functions astab 27 of needle 11, is rounded to form ashelf 170, upon which a T-bar rests as it is loaded intoneedle 151 in the direction indicated by arrow B. - Referring now to Figs. 16 and 17, there are shown front and right side views, respectively, of a
tagger gun nose 171 into which needle 151 may be removably mounted.Needle 151 is shown mounted innose 171 in Figs. 18 and 19. - The embodiments of the present invention described above are intended to be merely exemplary and those skilled in the art shall be able to make numerous variations and modifications to it without departing from the spirit of the present invention. All such variations and modifications are intended to be within the scope of the present invention as defined by the appended claims.
