- Figs. 5C and 5D' illustrate dispensing and applying a rebar fastener therefrom adjacent its distal end to form a parallel rebar junction.
- the invention in accordance with a preferred embodiment involves a semi ⁇ automatic rebar fastener-dispensing applicator or so-called 'gun' including a magazine for at least semi-automatically advancing a train of interlocked plural rebar fasteners toward a dispensing head where each successive one in the train is applied by manual pressure to a corresponding rebar junction thereby to fasten two lengths of rebar in a desired relative orientation whether parallel or perpendicular.
- semi ⁇ automatic is meant broadly either semi-automatic or fully automatic, whereby (respectively) little or no manual effort is required between successive rebar fastener applications.
- proximal and distal near and far from the supportive hands of the user of the invented rebar fastener gun will be referred to herein, respectively, as proximal and distal.
- the proximal end of the gun is that end normally nearer to the user's hand or hands and the distal end of the gun is that end normally farther from the user's hand or hands.
- the proximal end of the gun in accordance with one embodiment of the invention is a rebar fastener feeding and gun holding end and the distal end of the gun in accordance with the one embodiment of the invention is a rebar fastener dispensing end near the site of the rebar junction to be fastened.
- Fig. 1 is an isometric view of rebar fastener gun or applicator (device) 10 dimensioned and configured to apply rebar fasteners at ground level, with gun 10 in a generally vertical orientation.
- Gun 10 includes an elongate frame 12 configured to carry plural rebar fasteners F (shown in phantom), the frame including one or more elongate, preferably opposing races 14a, 14b for smoothly and securely guiding the fasteners therealong.
- Gun 10 further includes a feed mechanism 16 coupled with frame 12 for urging the fasteners toward a distal end 12a of the frame.
- Gun 10 further includes a dispensing head 18 adjacent the distal end of the frame, hi accordance with one embodiment of the invention, elongate frame 12 is configured adjacent distal end 12a thereof to curve approximately 90 degrees, such that forces exerted generally along the long axis of the elongate frame are transmitted outwardly therealong in a distal direction from dispensing head 18.
- frame 12 and dispensing head 18 are configured to dispense and apply plural fasteners F one at a time at corresponding rebar junctions, as will be described below by reference to Figs. 5C, 5D, 5C and 5D'.
- feed mechanism 16 includes an elongate coil spring 20 and a slide member 22.
- Elongate frame 12 in accordance with one embodiment of the invention includes one or more formed channel members 24a 5 24b that include the opposing races 14a, 14b.
- Opposing races 14a, 14b will be understood to extend substantially along the entire length of elongate frame 12 from distal end 12a to a proximal end 12b, thereby to smoothly and securely guide rebar fasteners F from an open feed inlet 26 to a closed feed outlet 28 within dispensing head 18.
- races 14a, 14b are configured within channel members 24a, 24b to capture, for elongate advancement therealong, the plural rebar fasteners F by engagement with oppositely extending guide pins thereof.
- fasteners having such guide pins preferably are manufactured in accordance with the teachings of the above- referenced PCT Patent Application Serial No. 05/30270. It will also be appreciated that, also in accordance with the teachings of that patent application, adjacent ones of the fasteners F in the so-called 'train' are interlocked with one another so that they remain securely in a train as they travel from the proximal end 12b of frame 12 to the distal end 12a thereof. In Fig.
- preferably applicator 10 is dimensioned such that a full magazine capacity is preferably approximately twenty- four (shorter gun) or thirty-nine (longer gun) fasteners F sized to accommodate 4- guage (1/2 inch) rebar lengths.
- a full magazine capacity is preferably approximately twenty- four (shorter gun) or thirty-nine (longer gun) fasteners F sized to accommodate 4- guage (1/2 inch) rebar lengths.
- larger gauge fasteners F proportionately reduce the magazine's capacity.
- straight and elongate channel member 24a and curved channel member 24b are affixed to one another effectively to produce a single, contiguous, elongate channel member that includes an approximately 90 degree curved distal end.
- gun 10 preferably includes an elongate rod 30 extending along and in parallel with and outer surface of channel member 24a between two frame-mounted capture mechanisms 32 and 34.
- a preferably tensile coil spring 20 (one that, when expanded, has a tendency to contract back to its original, normally compressed, relatively short extent) is coiled around a distal region of rod 30 and is captured between a frame-mounted stop member 36 and slide member 22.
- coil spring 20 opposite extreme ends of coil spring 20 are captured within slide member 22 and within stop member 36 so that, when a knob 38 mounted on slide member 22 is pulled by the user toward the proximal end of frame 12, coil spring 20 is extended and stores potential energy.
- knob 38 is released by the operator, slide member 22 and a pivotal gate 40 coupled therewith (the latter being in its first closed position illustrated in Fig. 1) are urged by conversion of stored energy into kinetic energy (i.e. by tensile force producing contraction) of spring 20 toward the distal end of frame 12 for the continuous feeding and dispensing of consecutive ones of plural interlocked fasteners F.
- spring 20 provides approximately five pounds of force
- gate 40 normally is in a first, closed position against stop fingers 40a, 40b (refer briefly to Fig. 4).
- gate 40 alternatively can be pivoted into a second, open position (refer briefly to Fig. 5A) for loading the magazine in a region thereof that is distal on frame 12 to slide member 22.
- coil spring 20 alternatively can be a compressile spring (one that, when compressed, has a tendency to expand back to its original, normally expanded, relatively long extent) that is coiled around a distal region of rod 30, as between fixed mounting member 32 and movable slide member 22.
- the means for leveraging for urging slide member 22 toward the distal end of frame 12 can take the form of a durable, reliable elastic member such as a woven elastic cord or hollow tube having adequate spring force.
- a sufficient force for feed mechanism to exert on the slide member will be understood to be that which quickly and reliably urges the train of interlocked fasteners F toward the distal end of frame 12 and snaps the penultimate fastener into dispensing position within dispensing head 18 of gun 10 when the ultimate fastener therein is removed (refer briefly to Figs. 5C, 5D, 5C and 5D'), regardless of the mass or orientation of the gun or the mass of the fastener clips.
- the invented gun alternatively may be used in a vertical orientation with the handle-end up and with the dispensing end up, e.g. to fasten rebar junctions in preparation for forming a concrete ceiling or roof, in which case the force of gravity must be overcome).
- any suitable alternative embodiments of the feed mechanism are contemplated as being within the spirit and scope of the invention.
- open face 28 of dispensing head 18 includes transverse channels 42, 44 configured to receive therein two lengths of rebar in either parallel or perpendicular relative orientation, thus facilitating the dispensing and application of a distal one of plural rebar fasteners F therearound to form a rebar junction.
- This operation of dispensing and applying a rebar fastener F to a rebar junction will be discussed in further detail below by reference to Figs. 5C, 5D, 5C and 5D'.
- U-shaped channel 42 is configured temporarily to receive therein one or more lengths of rebar extending along one or more axes Cl, C2 while generally U-shaped channel 44 transverse (and preferably perpendicular) thereto is configured temporarily to receive therein a length of rebar extending along axis C3.
- Gun 10 preferably includes one or more handles and preferably two or more handles, e.g. 46, 48, as shown, adjacent proximal end 12b of elongate frame 12. It can be seen that preferably the handles include comfortable grips, e.g. those made of durable, contoured rubber. One of the preferably two handles, e.g.
- handle 46 is adjacent a proximal end of frame 12 and is fixedly positioned, as shown, to extend downwardly at a slight angle (refer briefly to Fig. 2), i.e. to form a slightly acute angle with the long axis of frame 12.
- the other of the preferably two handles, e.g. handle 48, is pivotally adjustably positionable inwardly from proximal end 12b of elongate frame 12.
- gun 10 can be held by the user with left or right hands on handles 46, 48 to 'point' the gun and to force dispensing head 18 against a rebar junction to dispense and apply the distal rebar fastener thereat to securely capture two lengths of rebar in parallel orientation (along axes Cl, C2) or in perpendicular orientation (along axes C3 and C2) relative to one another.
- handle 48 is pivotally adjustable through 360 degrees to accommodate various user preferences and to increase force and torque efficiencies and to render the use of the gun as quick, effective and ergonomically strain- and repetitive motion-free as possible.
- Fig. 2 represents what will be referred to herein as an empty gun that needs to be refilled in accordance with the method illustrated in Figs. 5A-5B. It will also be appreciated that Fig. 2 illustrates the variable overall length L of gun 10 for accommodating different methods of use thereof, e.g. a greater length L of a gun in a generally vertical orientation for applying fasteners to horizontal junctions for concrete slabs or a lesser length L of a gun in a generally horizontal orientation for applying fasteners to vertical junctions for concrete walls or pillars.
- Handle 46 is attached to proximal end 12b of frame 12 by a U-shaped bracket 50 including dual lateral holes, as indicated, for alternative left- or right-handed placement thereof by appropriate fastening hardware such as Allen-headed machine screws.
- Gate 40 is pivotally mounted to U-shaped slide member 22 by rotatable Allen-headed machine screws attaching a generally cylindrical, formed channel in a proximal (hinged) end of the gate.
- Proximal mount 32 includes a machined clevis formed of opposing members 32a, 32b and suitable fastener hardware such as Allen- headed machine screws, the members having formed therein opposing semi- cylindrical channels for the interference fitted, fixed capture of rod 30 therein.
- Slide member 22 is provided with an oversize cylindrical bore 22a in a finger region 22b thereof to accommodate a polymer sleeve 22c for smoothly, slidably accommodating rod 30 therethrough.
- Dispensing head 18 includes two opposing formed bracket members 18a, 18b Allen-headed machine screwed into a terminal end of curved channel member 24b.
- the overall length of gun 10 in accordance with one embodiment intended to extend vertically and to reach the ground is approximately forty-one inches, with a depth including that of the fixed handle of approximately twelve inches and a width including the adjustable handle of approximately eight inches.
- the overall length of gun 10 intended to extend horizontally and to reach a wall or pillar is approximately twenty-seven inches.
- This variable length L (see Fig. 2) is indicated in Figs. 1-4 by a curved line pair discontiguity in frame members intermediate the proximal and distal ends of frame 12, e.g. channel member 24a.
- gun 10 in these two different embodiments are preferably identically constructed, except that they have different length dimensions including a longer or shorter frame 12 including a longer or shorter straight channel member 24a.
- the longer gun will be understood to be used to fasten horizontal rebar junctions by holding it generally waist high with the frame in a generally vertical orientation.
- the shorter gun will be understood to be used to fasten vertical rebar junctions by holding it generally chest high with the frame in a generally horizontal orientation.
- the magazine capacity of the longer gun is approximately thirty-nine fasteners F of a size that accommodates 4-guage (1/2-inch) rebar lengths and that the magazine capacity of the shorter gun is approximately twenty-four fasteners F of a size that accommodates 4-gauge rebar lengths. While the longer gun could be used to fasten vertical rebar junctions, those of skill in the art will appreciate that the slightly smaller capacity, smaller length and smaller weight of the shorter gun renders it easier to support in this cantilevered orientation relative to the user and that the shorter gun is somewhat more easier to use in smaller spaces providing smaller wingspan for the user.
- the gun embodiments described herein are both extremely durable and reliable, yet lightweight, e.g. only a few of pounds fully loaded with fasteners. This renders it very easy to maneuver during use and reduces labor and stress.
- the gun embodiments described herein also require no pneumatic or electrical power or umbilical cord, as they are manually operated. And despite the fact that they are manually operated and thus less expensive to use than power-assisted guns, nevertheless the gun embodiments described herein are very efficient and productive and fast to operate, with fully automatic manual cycle times as low as approximately 1-2 seconds and corresponding throughput rates as high as approximately 2000 fasteners per hour.
- Fig. 2 is a left-side elevation of gun 10 and Fig. 3 is a front elevation thereof.
- Fig. 2 perhaps best illustrates the 90 degree curved distal end 12a of frame 12 imparted by channel member 24b.
- Fig. 2 also best illustrates pivotable gate 40, which is shown in phantom in a second open position of its free (unhinged) end in which plural interlocked rebar fasteners F (not shown in Figs. 2 or 3 for the sake of simplicity and clarity) can pass therethrough to load the gun.
- This loading feature of the present invention will be further described below by reference to Figs. 5A-5B.
- FIG. 2 more clearly illustrates second channel 44 extending laterally through dispensing head 18, while Fig. 3 more clearly illustrates first channel 42 extending front-to-rear through dispensing head 18, the two channels extending transversely and preferably perpendicularly to one another.
- Figs. 2 and 3 also show a pivotable elongate arm 52 that mounts handle 48 for positioning.
- arm 52 is provided in accordance with one embodiment of the invention with plural axially arranged holes 52a, 52b, 52c, 52d (the last not being visible) for mounting handle 48 at a desired 'throw' radius from a central pivotal axis and adjustable mounting bolt 54, thereby providing a range of torques for manual gripping of gun 10 by the user.
- second handle 48 is adjustable in two ways — one positional and one angular — in accordance with one embodiment of the invention.
- Fig. 4 is a bottom view of gun 10. It shows how an ultimate or terminal fastener Fu is staged within dispensing head 18 for dispensing onto a rebar junction.
- transverse channels 42, 44 are aligned with corresponding conduits formed within fastener Fu made in accordance with the above-referenced PCT Patent Application Serial No. 05/30270.
- races 14a, 14b terminate within the dispensing head so that ultimate fastener Fu travels no farther than shown, thereby precisely aligning it for dispensing and applying to a rebar junction.
- opposite nylon bushings 56a, 56b and corresponding cinch plates 58a, 58b having inward recesses 58a', 58b' are provided in dispensing head in accordance with one embodiment of the invention.
- Recesses 58a', 58b' are dimensioned in their depth and length to correspond with the spacing apart of the guide pins of fastener Fu within races 14a, 14b.
- a thick plate 60 (preferably of machined aluminum) is provided to partially close dispensing head 18, as illustrated, and to mount the nylon bushings and the cinch plates.
- bushings 56a, 56b and cinch plates 58a, 58b mounted on plate 60 as described and illustrated herein will be referred to herein as a fastener capture-release mechanism that forms a part of dispensing head 18, the capture-release mechanism normally capturing the fastener positioned and oriented therein but being capable by a sufficient distally directed, axial force generally along frame 12 (as by the fastener's grip on a rebar junction and the forceful manual retreat or pull back of gun 10) to release the fastener from the dispensing head.
- Figs. 5A, 5B, 5C, 5D, 5C and 5D' are fragmentary isometric views of gun 10 being used in various phases of its intended operation. Specifically, Figs. 5 A and 5B illustrate loading and 'cocking' of the gun adjacent its proximate end, and Figs. 5C, 5D and 5C and 5D' illustrate important intermediate phases of dispensing a rebar fastener therefrom adjacent its distal end respectively for application to a perpendicular and a parallel rebar junction.
- Fig. 5A shows gate 40 in its open position that renders the rear surface of frame 12 unobstructed for the quick and easy loading of an interlocked train of plural rebar fasteners therein by sliding them into the open end with their guide pin pairs engaged within opposite races 14a, 14b.
- Fig. 5B shows gate 40 being swung back into its closed and stopped position that renders it stationary and capable of pushing the loaded train of plural rebar fasteners down the rear surface of frame 12 toward dispensing head 18. Loading is that easy.
- Fig. 5C shows ultimate fastener Fu poised immediately above a cross
- Fig. 5D shows ultimate fastener a moment later securing the rebar junction after the gun is forced against the junction.
- fastener Fu By virtue of the spring clip action of fastener Fu, the rebar junction is secure and the fastener Fu snugly and securely fastened thereto.
- fastener Fu remains securely fastened to the rebar junction and the guide pins and bushings 56a, 56b yield slightly and sufficiently to tug fastener Fu free of the gun.
- feed mechanism 16 advances fastener Fp into position in the terminus of dispending head 18 to be dispensed and applied to the next rebar junction. The process is repeated until the magazine is substantially exhausted, the gun is reloaded as described and the next series of plural rebar fasteners is applied.
- Figs. 5C and 5D' correspond identically to Figs. 5C and 5D described above, except for the relative orientation of the rebar lengths being joined, wherein Figs. 5C and 5D' illustrate applying a fastener to form a parallel rebar junction or so-called 'extension.
- the present invention is not limited to the method or detail of construction, fabrication, dimension, material, application or use described and illustrated herein. Indeed, any suitable variation of construction, fabrication, dimension, material, application or use is contemplated as an alternative embodiment, and thus is within the spirit and scope, of the invention. From the foregoing, those of skill in the art will appreciate that several advantages of the present invention include the following.
- the present invention provides a relatively inexpensive, semi-automatic means for conveying, dispensing and applying fasteners, for example to rebar junctions or the like, at increased speed, reduced labor cost and with less repetitive motion and potential stress-related injury.
- the invention provides a novel rebar fastener gun that is uniquely constructed for conveying a train of plural, interlocked rebar fasteners and for dispensing and applying them one at a time to form a rebar junction in parallel alignment in a so-called extension or in perpendicular alignment in a so-called cross.
- the gun includes a high-capacity magazine having a race, a spring- loaded feed mechanism, an angled dispensing head and one or more handles.
- the gun includes a fixed and an adjustable handle and a relatively short magazine, for use in applying rebar fasteners, e.g. in a generally vertical concrete pillar or wall, with the gun in a generally horizontal orientation.
- the gun includes a fixed and an adjustable handle and a relatively long magazine, for use in applying rebar fasteners, e.g. for a generally horizontal concrete slab, with the gun in a generally vertical orientation.
