Definitions
- the present invention relates to improvements to screw guides and cartridges such as those described in co-pending application PCT/AUOO/00676.
- some screw alignment devices as described in PCT/AUOO/00676, may in use from time to time have one or both of the head of a screw and or the screw driving end of the screw driver pop out of the screw guide.
- cartridges and screw guides described in PCT/AUOO/00676 can be complex to manufacture and thus the cost of manufacture can be such that the pricing in the market place of the cartridge system will be greater than the market is prepared to pay.
- a screw alignment device for assisting engagement of a screw driving tool during a fastening operation with a screw of the type having a shank disposed between a head end and a front end, the screw driving tool being of the type having a shaft with a gripping formation at one end thereof and an engaging formation at the other end thereof for engagement with the screw head
- the screw alignment device including: a screw guide having a body of generally annular configuration formed from a resilient material and having an internal cavity of generally frusto-conical configuration tapering convergently towards a forward end of the device, said screw guide including therein a slit therethrough wherein the slit provides an overlapping portion of one side of said screw guide with respect to the other side of said screw guide so that when overlapping portions of said screw guide on either side of said slit are moved apart with respect to each other as said screw head passes through said screw guide, said overlapping portions remain in an overlapped condition; a tool guide spaced rearwardly from the screw guide and
- the overlapping portions can be formed on either side of a generally circumferential closed slit which allows one side of said overlapping portion to slide over the other.
- the screw head size will need to be predetermined to prevent the overlapping portions from being separated to the point of not overlapping in use.
- the overlapping portion can be formed by a radially directed slit through the guide which also extends axially along the guide so that the slit lies on either side of a longitudinal axis of the screw guide.
- a slit can be shaped in a sinusoidal fashion, a zig zag fashion or other shape to produce at least one projection or finger which overlaps or lies across a straight line axis of said screw guide.
- the interlacing of the cuneiform portions of a zig zag on one side with the cuneiform portions on a zig zag on the other side will allow for the expansion of the slit without providing a clear radially directed path out of the screw guide for said screw head or said tool.
- the present invention provides a screw alignment device for use with a screw driving tool and a screw during a fastening operation, with said screw being of the type having a shank disposed between a screw head and a distal end, the screw driving tool being of the type having a shaft with a gripping formation at one end thereof and a screw engaging formation at the other end thereof for engagement with the screw head, said screw alignment device including: a screw guide having a body of generally annular configuration formed from a resilient material and having an internal cavity of generally frusto-conical configuration tapering convergently towards a forward end of the screw guide; a tool guide spaced rearwardly from the screw guide and aligned generally with an axis of said frusto-conical configuration; a connector which connects the screw guide to the tool guide; at least one cartridge receiving formation between said screw guide and said tool guide to receive a cartridge member thereon from which cartridge member at least one screw can be dispensed.
- a screw located on said cartridge is aligned with said screw guide and is engageable by said tool and moveable by the tool into the screw guide so as to be aligned generally with said axis of said frusto-conical configuration and so that the distal end of the screw projects through said forward end and the head of the screw being held by the screw guide, said screw and said tool being releasably held together in substantial alignment.
- the at least one carriage receiving formation can include means to releasably hold said cartridge member thereon.
- the cartridge receiving formation can include means to index the movement of said cartridge member through or across said cartridge receiving formation.
- the cartridge receiving formation can include a forward and rearward flange to slidably hold said cartridge member.
- Said flanges can include at least one projection or depression thereon for engaging said cartridge member.
- the cartridge receiving formation is preferably generally planar.
- the cartridge receiving formation can be formed as part of said connector.
- said screws are held onto said cartridge by means of adhesive.
- the adhesive can be in the form of adhesive tape.
- the screws can be dispensed from said cartridge by means of axial force and or by the rotation of said screw by said tool.
- the cartridge can include screw thread engagement means so as to enable the screw to be rotated on the cartridge and translate thereacross.
- the screw thread engagement means can be a forward and rear holding member so as to hold each screw at a forward and rearward location. Said forward and rearward members being spaced relative to each other and space from said screw guide when in use such that as said screw is rotated so as to travel towards said screw guide, said screw travels through said rearward member and breaks therethrough. By this time the forward end of said screw will be in said screw guide and remains aligned by virtue of the screw guide and the hold of said forward member. Further rotation of said screw will then break the hold of said forward member allowing the screw to proceed through the screw guide.
- the screw thread engagement means can be a series of depressions or projections to engage a screw thread.
- the series of depressions and or projections can be formed into the base of said cartridge or on a separate member which is attachable to said cartridge.
- the screw thread engagement means can alternatively be an adhesive, plastic or silicon holding formation which secures a screw to a cartridge base.
- the holding formation can be sufficiently rigid so that once set, a screw can be rotated in the holding formation allowing said screw to translate relative to the holding formation.
- the cartridge can include indexing means so that as said cartridge moves in said cartridge receiving means said cartridge will stop moving when a screw is aligned with said tool and said screw guide.
- the indexing means can include one or more projections or depressions associated with said cartridge receiving means which will cooperate with depressions or projections on said cartridge.
- the cartridge includes a multiplicity of screws thereon.
- said cartridge includes a profiled cross section to accommodate the shape of a screw so that each screw can be presented to said tool with its axis of rotation generally coincident with the axis of rotation of said tool.
- the cartridge can be manufactured from any suitable material such as cardboard, polymeric material etc.
- said cartridge is coloured so that the colour represents the type of screw on the cartridge or the use of those screws; such as for use with metal; or for use with hardwoods; or for use with medium or softwoods; or for use with plaster board; etc.
- the cartridge receiving means can be discrete channel portions mounted on the rear end of said screw guide and the forward end of the tool guide.
- the connector can include a concave upper surface which will cooperate with said channel portions to slidably capture and or index said cartridge.
- a cartridge used with such a cartridge receiving means can have a series of pockets which have an outside surface which is convex.
- the cartridge can have a series of pockets on only one side.
- Such a cartridge can includes at least one rail portion which extends along one edge of the cartridge.
- the edge is preferably a forward or rear edge.
- the rail portions fitting into said channel portions for guided movement of said cartridge in said rail portions.
- the rail portions can also serve to retain screws in said pockets.
- the cartridge is reusable.
- the spacing of said channel portions from said connector is such it is less than the spacing of said rail on said cartridge to the convex outside surface of the pockets.

- FIG. 1 to 3 Illustrated in Figures 1 to 3 is a screw alignment device 10.
- the screw alignment device 10 functions and is constructed in the same manner as that described in PCT/AUOO/00676 and that description is incorporated herein by reference.
- the frusto-conical shaped screw guide 12 has a radial slit 14 (radial in the sense that the separation plane through the slit extends through the screw guide 12 in a radial direction) which also extends axially along the surface of the screw guide 12.
- the slit 14 starts on the forward end 16 of the screw guide 16 on the right side of the screw guide 12 at location 18.
- the slit 14 then progresses in a straight line for a portion and then moves in a helical or slanted direction at 20 until a mid point (both with respect to the length and the width of the screw guide 12) is reached at 22.
- a similar shaped section 24 takes a helical or slanted path through the screw guide 12 as in Figure 3, with the slit 14 terminating in a straight line path section 26 which terminates at the rear end 28 of the screw guide 12 on the left side thereof.
- This slit 14 forms a portion 30 on one side of the screw guide 12 and a second portion 32 on the other side.
- the portions 30 and 32 are effectively projections or fingers which circumferentially extend around the longitudinal axis 34.
- the portions 30 and 32 will move away from each other thereby causing the slit 14 to become wider.
- the portions 32 and 30 effectively form fingers or projections which as can be seen from Figure 1 extend over the centre line 34, as the screw guide expands no path is provided for a screw head or the screw diving tool to radially escape from the screw guide 12.
- FIGS 7 and 8 Illustrated in Figures 7 and 8 are alternatively configured radial slits 14A and 14B.
- like parts have been like numbered with the embodiment illustrated in Figures 1 to 3.
- the two portions 30 and 32 each have as in Figure 7 fingers or projections 54 & 56 and 50 & 52
- the zig zag pattern provides fingers or projections (of cuneiform shape) 58&60&62 on portion 32 and 64&66&68 on portion 30.
- the slits 14A and 14B can be opened out quite considerably without the fingers or projections on portion 30 crossing over a vertical plane through longitudinal axis 34. These arrangements will thus also not provide a path for a screw head or a screw diving tool to radially escape from the screw guide 12 as the slits 14A and 14B expand.
- FIG. 4,5,6,and 6 A Illustrated in Figures 4,5,6,and 6 A is another embodiment which functions in a similar manner to those described above except that a generally circumferential slit 14C (circumferential in the sense that the separation plane through the slit extends through the screw guide 12 in a circumferential direction) is provided between the portions 30 and 32.
- the portions 30 and 32 act as overlapping flaps which overlie each other along the whole of the axial length of the screw guide 12, with a limit of circumferential overlap (see dimension Z in the enlarged view) being the amount of circumferential expansion the screw guide will take before a path is provided which will allow a screw head or the screw driving tool to escape the screw guide 12 in a radial direction therefrom.
- a similarly constructed overlap 60 can be provided on the tool guide portion 62 at the rear of the screw alignment device, as an alternative for the tool guide construction of the embodiments described in PCT/AUOO/00676.
- Figures 1 to 3 and 7 and 8 are readily adapted to a screw alignment device which is manufactured from nylon or from other polymeric materials such as those described in PCT/AUOO/00676 and are adapted for injection moulding.
- the embodiment of Figures 4,5,6 and 6A readily adapted to a screw guide when manufactured from sheet metal such as that specified in PCT/AUOO/00676.
- FIG. 9 to 11 Illustrated in Figures 9 to 11 is an embodiment of a screw alignment device 100 having a screw guide 102 at its forward end and a tool guide 104 at its rearward end.
- the screw guide 102 and the tool guide 104 are connected together by means of a connector 106 and are preferably integrally formed together.
- the connector 106 has thereon a cartridge receiving formation in the form of a platform 108.
- the platform 108 is positioned so as to be below an imaginary line representing the axis of rotation of a screw driver 110, which axis extends from the screw guide 102 to the tool guide 104.
- an L shaped forward flange 112 which has its upper portion 116 extending in a rearward direction, and an L shaped rearward flange 114 which has its upper portion 118 extending in a forward direction.
- the platform 108 and flanges 112 and 114 are integrally moulded with the connector 106, screw guide 102 and tool guide 104.
- the distances between the lower faces of portions 116 and 118 and the upper face of the platform 108 are approximately the thickness of a forward edge 126 and a rearward edge 128 respectively of a cartridge 120.
- the forward edge 126 of the cartridge 120 is of greater thickness by comparison to the rearward edge 128. The purpose of this will be described later.
- the L-shaped flanges 112 and 114 each have two curved projections 122 thereon. These projections 122 extend into the bights 130 on the cartridge 120 so that in use, when the projections 122 are located in the bights 130 a screw 140 will be located generally coincidently with the axis of rotation of the screw driver 110.
- Each screw 140 is held in spaced relation from adjacent screws by means of adhesive tape 142.
- the adhesive tape 142 includes on either side of each screw 140 a series of perforations 144 which assist the screw when in use in a screw alignment device 100, to break away therefrom.
- the adhesive tape 142 can also include a lubricant, which may be the adhesive or another lubricant added to the tape 142. The lubricant or the adhesive can assist in reducing the friction associated with the screw being driven into a material
- the screw 140 can be dispensed from the cartridge 120 by means of axial force exerted by the screw driver 110, or by axial force produced by the rotation of the screw 140 relative to the cartridge 120 by means of the screw driver 110.
- an inclined plane 136 is present between the rearward edge 128 and the forward edge 126. This inclined plane 136 allows the screw to be mounted on to the cartridge so that its axis of rotation is substantially coincident with the axis of rotation of the screw driver 110, when the cartridge is positioned on the platform 108 with projections 122 in the bights 130.
- FIG. 12 Illustrated in Figure 12 is an alternative cartridge 200 which is similar in shape to the cartridge 120 described above and like parts have been like numbered. Where the cartridges 100 and 200 differ is that the cartridge 200 has a forward rail 202 and rearward rail 204. Both rails 202 and 204 are formed by folding and gluing (or sonic welding or other appropriate joining process) the cardboard or sheet material from which the cartridge 200 is manufactured. This is illustrated in the cross section of Figure 13.
- the rails 202 and 204 can have a series of slots therein so that the screws 140 can be snapped into position on the cartridge 200.
- the height of the rails 202 and 204 above the upper surface of the cartridge 200 is such that the screw 140 can have its shank, and thus its axis of rotation, generally parallel to the upper surface of the cartridge 200.
- the cartridge 200 does not require a thicker forward edge by comparison to the rearward edge.
- the respective heights of L shaped flanges 112 and 114 of Figure 9 can be the same height to receive this cartridge 200.
- the cartridge 200 If it was desired to manufacture the cartridge 200 from injection moulded plastic it would have a cross section as illustrated in Figure 14. In which case respective holes in the rails 202 and 204 can be formed to receive the screws 140. Alternatively, as the cartridge 200 can be injection moulded the cartridge 200 can be injection moulded around an array of screws, thereby moulding and packaging in one step.
- Th cartridges 120 and 200 can be colour coded so as to indicate the types of screws mounted on the cartridge. For example a blue colour can be used to indicate that the screws are for use with metals; a red colour to indicate that the screws are for use with hardwoods; or an orange colour to indicate that the screws are for use with medium or softwoods; or a white colour to indicate that the screws are for use with plaster board.
- the colour can be contained within the plastics material, or the plastics material can be the colour concerned.
- an adhesive tape 142 can be used having these colours.
- FIG. 15 and 16 Illustrated in Figures 15 and 16 is a cartridge 300 which is similar to the cartridge 120 of Figure 10 and like parts have been like numbered.
- the cartridge 300 differs from the cartridge 120 by the presence of a series of formations 302, in this case depressions, which are impressed into the cardboard or plastic of the cartridge 300.
- the formations 302 can be projections formed on or added to the top surface of the cardboard or plastic of the cartridge 300.
- the formations 302 act as screw thread engagement formations so that when a screw thread is positioned on the cartridge 300 and secured thereto by adhesive frangible tape 142, the depressions and or projections in the formations 302 will allow translation of a screw 140 when that screw 140 is rotated on the cartridge 300.
- a screw 140 can have its shank substantially coincident with the axis of rotation of the screw driver 110, without the need for a tapered base like that of Figure 11.
- the pitch or distance between adjacent projections, adjacent projections and depressions or adjacent depressions in the formations 302 are preferably the same as the pitch of the screw thread on the screw 140 so as to provide the best possible thread interaction.
- FIG 17 Illustrated in Figure 17 is a plan view of a cartridge 400 similar to that of Figure 15, with like parts being like numbered.
- the cartridge 400 differs from cartridge 300 by the left and right edges 126 and 128 of the cartridge 400 having a series of indexing projections 131, which will engaged a series of depressions or apertures (not illustrated) which would replace the projections 122 present on the L-shaped flanges 112 and 114 of the screw alignment guide 100 of Figure 9.
- the cartridge 400 will thus function in the same manner as the previously described cartridges.
- FIG. 18 to 20 Illustrated in Figures 18 to 20 is another cartridge 500.
- the screws 140 are secured to a base 502 by means of a small quantity of silicone, plastic of other adhesive 504.
- the silicone, plastic or other adhesive 504 can also serve a lubrication function, or if desired a lubricant can be added to the adhesive or the screw so as to assist in reducing the friction associated with the driving of a screw into a material.
- the strip 506 has an array of formations 508 which are a series of depressions and projections, or a series of depressions, or a series of projections which will serve as screw thread engagement formations similar to the formations 302 of Figure 14.
- the strip 506 can have along its outboard edge as series of projections 131 to serve the indexing function described above.
- FIG. 21 and 22 Illustrated in Figure 21 and 22 is another cartridge 600.
- the cartridge 600 has the screws 140 attached to it by means of silicon, adhesive or melted plastic 602 which is able to set sufficiently so that once set, a screw 140 can be rotated on the cartridge 600 and thereby be translated on the cartridge for insertion into a surface to receive the screw 140.
- FIG. 23 and 24 Illustrated in Figures 23 and 24 is an alternative cartridge 700 for use with an alternative screw alignment guide 800.
- the screw alignment guide 800 is similar to the screw alignment guide of previous Figures in that there is present similarly shaped screw guide 802, tool guide 804 and a connector 806 joining them.
- the connector 806 differs from those above in that there is provided a concave upper surface 808 whose purpose will be discussed below.
- the rear of the screw guide 802 includes a left channel 810 and a right channel 812 which are in alignment with each other and which extend away from the screw guide 802. Similar left and right channels 814 and 816 extend away from the tool guide 804. The channels 814 and 816 are also in alignment with each other as well as with channels 810 and 812.
- the channels 810, 812, 814 and 816 receive a rail 702 and 704 on the cartridge 700.
- the rails 702 and 704 extend along the front and rear sides of the cartridge 700.
- the cartridge 700 is formed from a corrugated base 706.
- the corrugated base 706 has corrugations along both its upper and lower faces. Each corrugation forms a pocket or cavity 708 in which can be positioned a screw 140.
- the screws 140 are held in place by means of a tape 710 which can be colour coded and or lubricated as described above. Of course the screws in the pockets on the lower surface of the base 706 will be held in place by tape as well.
- the rails 702 and 704 are slid into the left channels 810 and 814, (or the right channels 812 and 816) until the outside undersurface 712 of the first pocket 708 engages the outside edge 820 of the connector 806 as illustrated in Figure 24.
- the cartridge 700 By application of force on the cartridge 700 relative to the screw alignment guide 800, the cartridge 700 can be moved in an indexed manner to the next pocket 708 which contains a screw to be dispensed..
- the cartridge 700 can be flipped 180 degrees and screws from the other face dispensed.
- the base 706 can be made wholly from plastic with an under and upper surface being present for each pocket so as to surround the screw leaving only openings at the front and rear for insertion of the screw and its dispensing from the cartridge. This could be made by upper and lower corrugated sheets being joined together to sandwich screws therein effectively placing each screw into a tube like formation.
