Abstract: A fastener collation tube (200), for retaining a plurality of fasteners (2) useable in a stand-up fastener driving tool (10), including an elongated body member having a channel having a substantially T-shaped cross section for receiving the fasteners (2) arranged side by side therein. At least one end of the elongated body member includes a resilient fasteners retaining member engageable with an endmost fastener of the plurality of fasteners (2) to retain the plurality of fasteners (2) in the channel, and disengagable from the endmost fastener to release the plurality of fasteners (2). The stand-up fastener driving tool (10) includes a fastener magazine (60) and a tube holder (180) coupled to the magazine (60) for receiving the fastener collation tube, wherein a prong (187) extending into the channel (182) of the tube holder (180) is engageable with the resilient fastener retaining member to disengage it from the endmost fastener disposed therein.

Description: The invention relates generally to stand-up fastener driving tools, and more particularly to fastener collation tubes for retaining a plurality of screw fasteners and useable in combination with a tube holder coupled to a fastener magazine of a stand-up fastener driving tool. The advent of stand-up fastener driving tools marked a significant advance in the installation of fasteners through overlapping members and into an underlying support member, collectively referred to herein as a deck, as is conventional in the roofing and flooring industries. U.S. Patent N° 5,302,068 for example, discloses a stand-up screw gun including generally a trigger actuatable rotary driver, which is an industrial quality hand-held electric tool, coupled to a screw driving member with a socket portion by a rotatable shaft extended through an outer upper tube coupled to the rotary driver and inner lower tube telescopingly biased away from the rotary driver by a compressed spring member disposed within the upper tube. The screw driving member of U.S. Patent N° 5,302,068 is movable from an inoperative position to an operative position relative to a nose-piece coupled to a distal end of the inner lower tube upon depressing the nose-piece against the deck to telescopingly move the inner lower tube toward the rotary driver against the bias of the compressed spring member. In the operative position, the socket portion engages a screw retained in a screw driving position between pivotal jaws of the nose-piece so that the screw is aligned axially with the screw driving member, whereupon continued depression of the nose-piece against the deck pivotally opens the jaws to release the screw and extends the screw driving member through the nose-piece, thereby driving the screw into the deck. According to a related aspect of U.S. Patent No. 5,302,068, the screw driving member includes a spring biased centering pin with a convex end disposeable in a concave recess formed in the screw head for axially centering the screw with the screw driving member, and more particularly with the socket portion thereof. In one embodiment, the convex end of the centering pin and the concave recess of the screw have complementary frusto-conical surfaces to rotationally orient the screw relative to the socket portion of the screw driving member, thereby facilitating engagement of the screw by the socket portion. The stand-up screw gun of U.S. Patent No. 5,302,068 also includes a screw feed tube disposed alongside the telescoping upper and lower tubes. An upper end of the feed tube includes a funnel to facilitate manual insertion of screws therein, wherein the screws are gravity fed from the upper end of the feed tube toward a lower end thereof, which is coupled to the nose-piece by a mounting block. A passage through the mounting block directs screws from the feed tube to the screw driving position between the pivotal jaws of the nose-piece when the screw driving member is retracted away from the nose-piece in the inoperative position. In many stand-up fastener driving tools, including the stand-up screw gun of U.S. Patent No. 5,302,068, the operator must insert each screw into the feed tube individually, wherein a second screw cannot be inserted into the feed tube until the previously inserted screw has been driven into the deck. Feeding more than one screw into the feed tube may result in obstruction of the screw driving member as it moves between the inoperative and operative positions. And feeding a second screw into the feed tube while the screw driving member is in the operative position may prevent the screw driving member from retracting fully away from the nose-piece after installation of a previously fed screw. The object of the present invention is to eliminate the necessity of manually inserting each screw into the feed tube prior to installation, only after a previously inserted screw has been installed into the deck, which is time consuming and distracting. Others have endeavored to provide improved fastener loading features in stand-up fastener driving tools. U.S. Patent N° 3,960,191, for example, discloses a stand-up screw gun having a feed tube for retaining a plurality of screws therein. The feed tube is coupled to a nose-piece disposed on an end of a telescoping tube assembly. A pivotal arm alternately positions ears at opposing ends thereof into the feed tube during retraction and extension of the telescoping tubes, wherein the ears of the pivotal arm release one of a plurality of screws retained in the feed tube toward the nose-piece as the telescoping tube assembly is extended after installation of a previously released screw. More recently, U.S. Patent N° 5,199,625, discloses a flexible tube for retaining several pins disposed therein, and for directing the pins into a slot formed in a nose-piece of a stand-up fastener driving tool. A shuttle member is movable transversely in the slot toward an aperture of the nose-piece to transfer a pin disposed in the slot to the aperture of the nose-piece where the pin is retained by a magnet in axial alignment with the pin driving member until the pin is engaged thereby. The shuttle permits only one pin at a time from dropping form the feed tube into the slot, which occurs when the shuttle is retracted away from the aperture of the nose-piece. The configurations of U.S. Patent Nos. 5,302,068 and 3,960,191 require that the screws be loaded individually into the feed tube by the operator, which is often a distracting and arduous task in the field, particularly during inclement weather conditions and at precarious work sites. And although the configurations of U.S. Patent Nos. 5,199,625 and 3,960,191 include a fastener feed tube portion for retaining a plurality of screws or pins therein for use during tool operation, the screws or pins must be loaded, or stacked, into the feed tube in a head-to-point relationship, which limits the number of fasteners retainable therein. U.S. Patent N° 4,199,093 discloses a tube assembly for housing a plurality of charge packages arranged end to end therein for use by a power actuated tool. An open end portion of the tube is deformably constricted by a separate resilient ring disposed thereabout to retain the charge packages therein. A loading device of the tool includes end portions projecting into the tube to expand the constricted portion thereof outwardly against the bias of the resilient ring to allow the charges disposed in the tube to be transferred into the tool. The tube assemby of U.S. Patent N° 4,199,093 however houses the charge packages in an end-to-end arrangement, which limits the number of charges retainable therein. Also, the tube assembly of U.S. Patent N° 4,199,093 has multiple components including the separate resilient ring, which requires assembly and increases production costs. EP 600 283 A1 discloses a fastener collation device for retaining a plurality of fasteners side by side in a channel. The device of EP 600 283 A1 is not tube shaped and not of a T-shapes cross section. The present invention is directed toward novel advancements in the art of fastener collation tubes for retaining a plurality of fasteners useable in stand-up fastener driving tools. It is thus an object of the invention to provide a novel fastener collation tube for retaining a plurality of fasteners useable in stand-up fastener driving tools, and combinations thereof, that overcome problems with the prior art, and that are economical and reliable. Therefore, the instant application relates first to a fastener collation tube for retaining a plurality of fasteners according to claim 1. In the preferred embodiment , the fastener collation tube of the invention comprises the features as claimed in any one of the subclaims depending on claim 1 or a combination thereof. The instant application relates also to a combination of the fastener collation tube as claimed and a stand-up fastener driving tool according to one of claims 8 to 12. These and other objects, features, aspects and advantages of the present invention will become more fully apparent upon careful consideration of the following detailed description of the Invention and the accompanying drawings, which may be disproportionate for ease of understanding, wherein like structure and steps are referenced generally by corresponding numerals and indicators. In the drawings, FIG. 1a is a partial side view of an upper portion of a stand-up fastener driving tool including a fastener magazine and dispenser assembly according to an exemplary embodiment of the invention ; FIG. 1b is a partial side view of a lower portion of a stand-up fastener driving tool including a nose-piece thereof, which forms a part of the stand-up fastener driving tool of FIG. 1a.; FIG. 2 is a side elevational view of a fastener collation tube useable in combination with the stand-up fastener driving tool of FIG. 1; FIG. 3 is a sectional view along lines a - a of FIG. 2; FIG. 4 is an end view along lines b - b of FIG. 2 illustrating also a fastener retained within a channel of the fastener collation tube and FIG. 5 is a partial end view along lines c - c of FIG. 1a illustrating a fastener collation tube disposed in the fastener tube holder. FIGS. 1a-1b illustrate a fastener driving tool 10 comprising generally a rotary driver 12, which may be an electric tool actuatable by a trigger 14, having a rotatable shaft 16 with a fastener driving member 20 disposed on a distal end of the rotatable shaft 16. The exemplary fastener driving member 20 includes a socket 22 engageable with a frusto-conical shaped fastener head and an axially aligned pin 24 biased into the socket 22 for aligning a fastener 2 with the socket 22 as disclosed more fully in an embodiment of U.S. Patent N° 5,302,068 and incorporated by reference herein. The stand-up fastener driving tool 10 includes also a lower tube 30 telescopingly coupled to an upper tube 40 having an upper end 42 coupled to the rotary driver 12. The lower tube 30 has a lower end 32 biased away from the rotary driver 12 by a spring member 44 disposed within the upper tube 40. A nose-piece 50 is coupled to the lower end 32 of the lower tube 30, wherein the nose-piece 50 includes generally an opening 52 for retaining the fastener 2 in a fastener driving position aligned axially with the fastener driving member 20 disposed axially in the lower tube 30. The fastener driving member 20 is extendable toward the nose-piece 50 upon contraction of the lower tube 30 relative to the upper tube 40 against the bias of the compressed spring 44, and the fastener driving member 20 is retractable away from the nose-piece 50 upon extension of the lower tube relative to the upper tube. The nose-piece 50 of the exemplary embodiment of FIG. 1 includes two jaws 54 having corresponding fastener retaining ends 55, which are pivotally biased toward each other about a corresponding pivot 53 by a corresponding spring member 56 to at least partially define the opening 52 between the fastener retaining ends 55. The nose-piece 50 also includes two opposing plate members 58, only one of which is shown in FIG. 1b, coupled to the lower end 32 of the lower tube 30 and pivotally supporting the two jaws 54. A tip 59 of the plate members 58 is depressably engageable against a deck, or workpiece, not shown, for contracting the lower tube 30 relative to the upper tube 40, whereupon the fastener driving member 20 is extendable toward the nose-piece 50 and is engageable with a fastener 2 retained between the jaws 54 thereof as the lower tube 30 is contracted relative to the upper tube 40. Further contraction of the lower tube 30 relative to the upper tube 40 extends the fastener 2 engaged by the fastener driving member 20 between the jaws 54, which are pivoted away from each other against the bias of spring members 56 to increase the opening 52 therebetween, thereby releasing the fastener 2 from the jaws 54, whereby the fastener is installable into the workpiece. Various configurations of the fastener driving member 20 and the nose-piece 50 and the operation thereof are disclosed more fully in U.S. Patent No. 5,302,068 FIG. 1 illustrates the stand-up fastener driving tool 10 including a magazine 60 having a slot 70 between opposing guide rails 62 thereof and one or more upper and lower pins 64 and 66 actuateably extendable into and retractable out of the magazine slot 70 for retaining a plurality of fasteners arranged side by side in an upper portion 71 of the magazine slot 70. The exemplary embodiment includes two upper pins 64 et 65 and only one lower pin 66, but other configurations may also include two lower pins. The upper pins 64 and 65 are extended into the magazine slot 70 and the lower pin 66 is retracted out of the magazine slot 70 as the lower tube 30 is extended relative to the upper tube 40, wherein the upper pins 64 and 65 retain the plurality of fasteners in the upper portion 71 of the magazine slot 70 as shown. Only a single fastener 2 is shown in FIG. 1 to reduce the complexity of the drawing. The lower pin 66 is substantially alternately extendable into the magazine slot 70 and the upper pin is retractable out of the magazine slot 70 as the lower tube 30 is contracted relative to the upper tube 40, wherein the lower pin 66 retains the plurality of fasteners in the magazine 70. In some configurations, both the upper and lower pins may be extended into the magazine slot 70 simultaneously during some phase of the contraction and extension of the upper and lower tubes 30 and 40. FIG. 1a illustrates the magazine 60 coupled to a tube holder 180 including a longitudinal channel 182 for receiving a fastener collation tube 200, shown also in FIG. 2. The channel 182 of the tube holder 180 is aligned with and coupled to the upper portion 71 of the magazine slot 70. FIG. 5 illustrates edge portions 183 and 185 formed on a portion of the magazine 60 toward the tube holder 180, wherein the edge portions 183 and 185 form an abutment surface against which the fastener collation tube 200 is seatable when disposed in the tube bolder 180. FIGS. 3 and 4 illustrate the fastener collation tube 200 including an elongated body member 208 having a channel 210 for retaining a plurality of fasteners 2 having a head 6 and a shank 7 arranged side by side therein. The fasteners in the exemplary embodiment are screw fasteners. The fastener collation tube 200 is removably disposeable in the channel 182 of the tube holder 180 to couple the channel 210 of the fastener collation tube 200 with the magazine slot 70, whereby the plurality of fasteners arranged side by side in the fastener collation tube 200 are transferrable to and disposeably retained in the upper portion 71 of the magazine slot 70. The fastener collation tube 200 may be removed from channel 182 of the tube holder 180 upon transferring the fasteners into the magazine 60, since a supply of fasteners is retained in the upper portion 71 of the magazine slot 70 for use during operation of the stand-up fastener driving tool 10. Alternatively, the fastener collation tube 200 may remain in the channel 182 of the tube holder 180 during operation of the tool 10, whereby the channel 210 of the fastener collation tube 200 extends the upper portion 71 of the magazine slot 70. FIGS. 3 and 4 illustrate, more particularly, the channel 210 of the fastener collation tube having a substantially T-shaped cross section defined by opposing side walls 212 and 214 adjacent the fastener shank 7, opposing side wall shoulders 215 and 216 adjacent a bottom surface 5 of the fastener head 6, an end wall 218 adjacent a top surface 8 of the fastener head 6, and substantially opposing crown portions 219 and 220 adjacent a circumferential fastener head side portion 9 between the opposing side wall shoulders 215 and 216 and the end wall 218. And though the end wall 218 and the crown portions 219 and 220 have arcuate surfaces in the exemplary embodiment, alternative embodiments may have other forms. The end wall 218 and the crown portions 219 and 220 may, for example, have relatively linear surfaces, or may have a substantially continuously curved surface. The fastener collation tube 200 includes generally a resilient fastener retaining member for retaining the fasteners in the channel 210 thereof. In the exemplary embodiment of FIGS. 2, 3 and 4, the fastener retaining member comprises two resilient tabs 222 and 224 located toward opposing first and second ends 202 and 204 thereof, wherein the resilient tabs 222 and 224 protrude into the channel 210 of the elongated body member 208 from corresponding crown portions 219 and 220 between the corresponding shoulders 215 and 216 and the end wall 218. In alternative embodiments, however, one end of the fastener collation tube 200 may be capped or blocked by other means, and the resilient tabs 222 and 224 may be disposed near or on only one end of the elongated body member 208. In other alternative embodiments, a single resilient tab extends into the channel 210 of the elongated body member 208 from only one of the opposing side walls 212 and 214, or from opposing crown portions 219 and 220, or from the end wall 218 thereof. And in other alternative embodiments, the fastener retaining member is a crimped, or a twisted, or a bent end portion of the elongated body member 208. The resilient tabs 222 and 224 are oriented to extend away from corresponding open ends 203 and 205 of the elongated body member 208 and into the channel 210 thereof. According to this aspect of the invention, the resilient tabs 222 and 224 are flexible out of the channel 210 as fasteners are disposed into the channel 210 from one of the open ends 203 or 205, thereby allowing insertion of fasteners into the channel 210 of the elongated body member 208. FIGS. 3 and 4 illustrate end portions 232 and 234 of the resilient tabs 222 and 224 engageable with the plurality of fasteners in the channel 210 of the fastener collation tube 200 to retain the fasteners therein. More particularly, the end portions 232 and 234 of the resilient tabs 222 and 224 are engageable with an endmost fastener 2 of the plurality of fasteners disposed in the channel 210 of the fastener collation tube 200 to retain the plurality of fasteners therein. The resilient tabs 222 and 224 thus function as a one-way gate allowing fasteners to be inserted into the fastener collation tube 200, and preventing fasteners .from falling out of the channel 210 thereof until the flexible tabs 222 and 224 are disengaged from the fasteners by flexing out of the channel 210 as discussed further below. The fastener collation tubes 200 are thus reusable. In the exemplary embodiment, the resilient tabs 222 and 224 are formed of corresponding partially cut portions of the elongated body member 208, thereby forming a unitary fastener collation tube 200. The fastener collation tube 200 may for example be formed of plastic in a molding or extruding process. And the resilient tabs 222 and 224 may be formed in a stamping or cutting operation on the elongated body member, wherein the cut resilient tabs 222 and 224 are subsequently depressed inwardly into the channel 210 of the elongated body member 205 to retain the screw fasteners therein as discussed above. FIGS. 1 and 5 illustrate prongs 186 and 187 extending into the tube holder 180, wherein the prongs 186 and 187 are extendable into the channel 210 of the fastener collation tube 200 and engageable with corresponding resilient tabs 222 and 224 of the fastener collation tube 200 to flex the resilient tabs 222 and 224 out of the channel 210 thereof when the fastener collation tube 200 is disposed in the channel 182 of the tube holder 180, whereby the fasteners retained side by side in the fastener collation tube 200 are released therefrom and transferred into the magazine slot 70, and more particularly into the upper portion 71 thereof. In other embodiments, a single prong extending into the tube holder 180 flexes a corresponding single resilient tab in configurations of the fastener collation tube 200 having only one resilient tab protruding into the channel 210 thereof. FIGS. 1 and 5 also illustrate an alignment-prong 190 extendable away from the end wall 79 of the magazine slot 70 and engageable with a top side 221 of the fastener collation tube 200 opposite the end wall 218 thereof. The alignment prong 190 is disposed at an angle relative to the axis of the tube holder 180 to engage and bias the fastener collation tube 200 toward the shoulders 77 and 78 of the magazine slot 70 as the fastener collation tube 200 is disposed in the channel 182 of the tube holder 180. The top side 221 of the elongated body member 208 has a concave surface to facilitate cooperative engagement by the alignment prong 190. The alignment prong 190 thus aligns or positions the end wall 218 of fastener collation tube 200 relative to the end wall 79 of the magazine slot 70 when the fastener collation tube 200 is disposed into the channel 182 of the tube holder 180 to prevent obstruction of the fasteners by the end wall 79 of the magazine slot 70 as the fasteners are transferred from the fastener collation tube 200 into the upper portion 71 of the magazine slot 70. FIG. 5 illustrates end portions of the opposing side walls 212 and 214 of the fastener collation tube 200, and more particularly portions of either end 203 or end 205, supportably disposed on the edge portions 183 and 185 of the magazine 60, which are correspondingly aligned with the opposing side walls 212 and 214 thereby providing support for the fastener collation tube 200. The edge portions 183 and 185 thus form an abutment surface against which the fastener collation tube 200 is seatable when disposed in the tube holder 180. The fastener collation tube 200 is retained generally in the tube holder 180 by frictional forces therebetween, which permits operation of the stand-up fastener driving tool 10 when the fastener collation tube 200 is disposed in the tube holder 180, without separation of the fastener collation tube 200 therefrom during operation and handling of the stand-up fastener driving tool 1C. In application, generally, a plurality of fasteners are securely retained in the fastener collation tube 200, which is readily loadable into the tube holder 180 of the stand-up fastener driving tool 10 to transfer the plurality of fasteners into the magazine slot 70 thereof. The fastener collation tube 200 may be removed from the tube holder 180 upon transferring the fasteners therefrom into the upper portion 71 of the magazine slot 70, whereupon the stand-up fastener driving tool 10 is operational without the fastener collation tube 200. As discussed above, however, the stand-up fastener driving tool 10 is operational with the fastener collation tube 200 disposed in the tube holder 180. The fastener collation tube 200 is also readily removable from the tube holder 180 when depleted of fasteners, and is reusable upon reloading a plurality of fasteners therein. Tool operators may thus carry several fastener collation tubes 200 loaded with fasteners, and conveniently load the fastener collation tubes 200 into the tube holder 180 of the stand-up fastener driving tool 10 whether or not fasteners remain in the upper portion 71 of the magazine slot 70 thereby permitting relatively uninterruptable operation of the tool 10.
