Definitions

  • the present disclosure relates to generally fastening systems employed to connect wood structural members to comply with construction codes.
  • the present disclosure relates generally to tools and methods for installing a fastener to secure wood framing components. More particularly, this disclosure relates to tools and techniques to precisely install fasteners to secure the top plate to roof trusses or rafters.
  • Document US 2014/0161561 A1 discloses a system for positioning a tool according to the preamble of claims 1 and 10, including a base member configured to contact a first decking member and a second decking member to secure said decking members to a joist with a fastener.
  • Local and state building codes which are typically based on universal codes such as the International Residential Code and the International Building Code, set forth various requirements for securing wooden framing components. Provisions are made in such codes to require that the top plate and the rafters, or roof trusses, must be connected to comply with pre-established connection force standards calculated to resist substantial uplift forces that may be experienced throughout the lifetime of the structure. For locations which are susceptible to high wind uplift and/or seismic activity, typically, a stronger forceresistant connection between the top plate and rafters or trusses is required.
  • CLP continuous load path
  • hurricane clips or other forms of metal straps or clips are traditionally used and secured by multiple nails or threaded fasteners.
  • connection integrity and construction efficiency For example, hurricane clips, which are effective and widely used in many locations, may require eight or more nails or threaded fasteners to meet the requisite code connection standard.
  • threaded fasteners such as elongated screws to replace some of the metal brackets and nails currently employed to meet building codes.
  • such screws need to be installed at a particular angle and position to ensure penetration through several wood members to engage, for example, a roof truss or rafter.
  • a construction system that would facilitate the use of threaded fasteners to connect building components in a manner that meets building codes and allows building inspectors to visually confirm correct installation of such threaded fasteners.
  • a highly secure and efficient connection between the top plate and rafters or roof trusses can be implemented by employing multiple specialty six-inch threaded fasteners, such as TimberLOK ® wood screws manufactured and marketed by OMG, Inc., of Agawam, Massachusetts.
  • each threaded fastener is driven through the top plate and into the rafters or roof trusses at a 22.5 ⁇ 5° optimum angle with respect to the vertical.
  • securing multiple threaded fasteners is typically more efficient than attaching a hurricane clip or other strap-type connector, it is difficult to consistently implement a 22.5° angle within a reasonable range of precision.
  • the usage of protractors, levels and other similar-type tools to obtain the optimum angle for the threaded fastener has proven to be clumsy, difficult, time consuming and, at best, only marginally advantageous over more conventional securement methods.
  • the present disclosure addresses the need for a tool and method to connect the top plate and rafters or roof trusses by efficiently installing multiple threaded fasteners having a consistently precise optimum connection angle.
  • a dual positionable adaptor mounts to a fastener driver assembly to provide a location and an entry angle for driving a fastener to provide an optimum connection for various wood structural components.

  • a connector is configured to mount the guide head to the driver assembly so that the fastener is driven through the opening.
  • a guide assembly is mounted to the guide head.
  • the guide assembly comprises a pair of spaced arms having opposed faces. Each arm has a first engagement edge and a second engagement edge at an angle to the first engagement edge. The first engagement edges are coplanar, and the second engagement edges are coplanar.
  • a fastener is drivable by the fastener assembly through the fastener opening at an oblique entry angle to the vertical member.
  • a fastener is drivable by the fastener assembly through the fastener opening at an oblique entry angle to the vertical member.
  • the entry angle is approximately 35°.

  • the fastener installation tool 10 is a heavy-duty hand tool adapted for installing threaded fasteners 12 at a consistent angle of approximately 22 1/2° (to the vertical) into a top plate for connection with a roof support member.
  • a top plate 22 which may include a single 2x4 or a double 2x4, is mounted at the top of spaced vertical studs 24. Roof support members 26 of roof trusses 28 are mounted and supported on the top plate 22. Threaded fasteners 12 are driven into the top plate at a 22 1/2° angle for engagement with the roof support member 26. Multiple spaced threaded fasteners 12 are sequentially driven at pre-established spacings to provide the proper uplift resistance.

  • the installation tool 10 is preferably dimensioned, principally by means of the length of a telescopic tube assembly 30, to provide an installation tool which may be effectively used by installers having a wide range of height and reach for a wide range of commonly vertically dimensioned structures.
  • the principal function of the telescopic tube assembly 30 is to exert positive forward or upward pressure against the top plate/roof support interface.
  • representative tube assembly lengths are designated by L and l and representative fastener lengths are designated by D and d which also represents the travel distance to drive the screws.
  • the telescopic tube assembly 30 preferably has a maximum length of between 69.6 cm (27.4 inches ) and 91.8 cm (36.14 inches) to accommodate the height and reach of the installer. For a six-inch fastener 12, the telescopic assembly 30 must retract 6 inches to drive the fastener, as will be described below.
  • the installation tool 10 dimensions allow for the tool to be effectively and efficiently used for connecting the top plates 22 to the roof support members 26 without requiring the use of a ladder, platforms or other means for providing the proper effective height relationship for driving the fasteners 12.
  • the proper fastener angle may be sequentially implemented from location to location along the top plate 22 to ensure a proper consistent angle for each of the multiple fasteners and to provide an integrated composite connection having an uplift resistance of high integrity.

  • the telescopic tube assembly 30 comprises a proximal tube 32 which receives and mounts the driver 42 and a longer tube 34 secured to the tube 32.
  • tube 32 slides relative to tube 34 which essentially remains stationary in relation to the components to be connected by the fastener.
  • Tube 34 terminates in a distal end 36.
  • a fastener guide assembly 50 is mounted at the distal tip 36 of the tube assembly.
  • the guide assembly 50 provides the proper alignment structure for implementing the preferred 22 1/2° entry angle for the fastener.
  • the assembly 50 also engages the support member for stabilizing the installation tool during the driving process.
  • the guide assembly 50 is dimensioned in accordance with the dimensions of a given fastener.
  • the guide assembly has a fastener channel 52 which functions to receive and load the fastener in a muzzle-loading fashion.
  • the fastener drill tip 16 is positioned proximate the channel opening 53. The fastener is inserted head 14 first into the fastener channel 52 of the guide assembly.
  • the fastener head 14 is engaged by a complementary torque coupler 43, such as a socket, for a hex thread fastener or a projecting coupler for a fastening head socket at the applicator end of the torque drive assembly train 45.
  • the drive train 45 which may include multiple components, extends through and is housed within the tube assembly 30 and is driven by the torque driver 42.
  • guide assembly 50 is preferably a cast or molded member of a lightweight rigid form which is mounted at the distal end 36 of the tube assembly.
  • the guide assembly 50 has a frame 60 with a planar locating or engagement surface 62 disposed at an acute angle with respect to lower planar mounting surface 64.
  • Mounting surface 64 preferably engages against the end of the tube assembly and transversely extends across the end of the tube 34.
  • a planar end plate 66 is preferably perpendicular to surface 62 and is positioned and configured to closely approach or even contact the underside of the roof support member 26 (as will be explained below).
  • the acute angle is preferably 22 1/2°, although other angles may be provided depending on the intended application of the installation tool 10.
  • the fastener channel 52 which may be formed by a cylinder, has a central axis which is perpendicular to the surface 64.
  • the fastener channel axis is disposed at an acute angle of preferably 22 1/2° to the surface 62.
  • Surface 62 defines the channel opening 53.
  • the channel 52 receives the fastener 12 so that the head 14 is proximate and readily engageable with the torque coupler 43.
  • a transverse slot 65 receives an alignment bracket 68 having a T-shaped section which protrudes transversely at opposed sides of the engagement surface 62 and also projects outwardly from the surface 62.
  • the alignment bracket 68 is positioned and configured to fit or ride below the 2x4 of the top plate 22 to ensure proper perpendicular alignment with the top plate 22.
  • the alignment bracket 68 may be secured in the frame by a friction or interference fit or may be secured by a fastener (not illustrated) to the frame and can be transversely moved.
  • the bracket C is located approximately 4.13 cm (1 5/8 inches) below the end plate 68.
  • the upper portion of the frame is traversed by a slot 69 which receives a metal stabilizer plate 70.
  • the stabilizer plate is secured in place by a threaded adjustment knob 72.
  • the knob 72 connects with a threaded rod 74.
  • the rod extends through an opening in the plate 70 and threads into a central threaded opening 75.
  • the stabilizer plate 70 preferably has a square configuration with four vertices which form edges 76. The edges 76 are sharpened. When the plate 70 is mounted in position, one edge 76 or vertex projects upwardly from the end surface 66 of the frame. Openings 78 are provided in the plate to provide a height adjustment for vaulted ceilings and other configurations. Alternatively, the projecting structure is in the form of a barb.
  • the function of the stabilizer plate 70 is to provide a stabbing point to engage into the wood proximate the interface of the top plate 22 and the roof support member 26 to thereby stabilize the tool and prevent movement while the fastener is being torqued by the installation tool.
  • the stabilization is especially important at the initial stages of driving the fastener.
  • the stabilizer plate functions to present a stabbing point so that upon inspection, an inspector will readily perceive that the fastener is at the proper angle.
  • the guide assembly 50 is positioned by the installer at the intersection of the top plate 22 and the roof support member 26 with the projecting stabilizer plate edge 76 engaging into the wood and the engagement surface 62 engaging in surface-to-surface relationship against the vertical side of the top plate 22.
  • the end surface 66 is typically positioned proximate the underside of the roof support member 26, but is slightly offset due to the less than complete penetration of the stabilizer edge, and the alignment bracket 68 engages the lower edge portion of the top plate 22.
  • a fastener 12 Prior to engagement of the guide assembly with the top plate/roof support structure (as previously described), a fastener 12 is dropped into the fastener channel 52 with the fastener head 14 proximate to or engaging with the complementary coupler 43. A portion of the fastener 12 is typically initially received in a chamber of tube 34 adjacent the distal end 36. The fastener drill tip 16 is proximate the channel opening 53 in the engagement plate 62. It will be appreciated that the guide assembly 50 as properly positioned provides the proper entry point and entry angle for the fastener 12 as the fastener is driven through the top plate 22 into the roof support member 26.
  • guide head 150A and guide head 150B alternative embodiments of the guide assembly that mount to the end of the telescopic tube assembly of an installation tool are generally designated as guide head 150A and guide head 150B, respectively.
  • These guide heads include additional features both for providing the proper alignment and positioning for the screw and for enhancing the ability of the operator and/or an inspector to verify that a proper connection has been made.
  • Each of the guide heads has a frame 160 with a planar locating surface 162 disposed at an acute angle with respect to a tube assembly. Locating surface 162 defines a channel opening for the fastener channel access of the tube assembly.
  • a planar end plate 166 is configured to engage or closely approach the underside of the roof support member 26.
  • Bracket 168 may be adjustable.
  • a pair of arms 180 and 182 are pivotally mounted at the top of the frame. One or more of the arms 180 and 182 may be pivoted upwardly to engage a vertical side of member 26 and provide a proper positioning relative to the roof support member 26.
  • a stabber point 170 projects through the end plate 166.
  • the upper portion of the frame mounts a linear ink pad 190.
  • the guide heads 160A and 160B have not been positioned against the roof support member 26.
  • the pivotal arms 180 and 182 would engage against the sides of the support member 26, and the ink pad would make a linear mark indicated at 191 on the bottom of the roof support member 26.
  • the stabber 170 would stab into the wood and leave a mark 171 as indicated. It should be appreciated that either the ink mark 191 or the stab mark 171 could be used to identify both the proper fastener as well as the proper entry angle of the fastener and accordingly indicate that a proper connection has been completed.
  • the guide head 150B illustrated in Fig. 43 has a pair of barbs 176 projecting from the end plate 166. When properly engaged under the roof support member 26, the pair of barbs would provide two marks 177 which would again provide a unique marking for indicating the proper connection. Of course, the barbs 176 also enhance the stability of the installation tool and the fastener during the installation process.
  • the installation tool preferably includes an auxiliary handle (in addition to the handle on the driver 40) to facilitate two-handed positioning and stability during the driving process.
  • auxiliary handle in addition to the handle on the driver 40 to facilitate two-handed positioning and stability during the driving process.
  • Various auxiliary handle configurations can be employed.

  • the handle 80 includes a rear grip 82 which radially projects radially or quasi-radially relative to the longitudinal axis of the tube assembly.
  • a forward rod 84 extends from the grip generally parallel to the tube assembly.
  • the rod 84 connects to a forward yoke 86 which envelopes the outer surface of the tube assembly and is slidable along the tube assembly.
  • the intermediate portion of the rod is received in a cam lock 88 carried by the fixed proximal tube 32 that mounts to the forward portion of the driver 42. The rod locks in place with the cam lock 88.
  • the tube 34 telescopes with the proximal tube 32 and is slidably receivable throughout the driving of the fastener 12 in the installation process as the fastener is driven to complete the connection.
  • the changing dynamic relationships of the fastener 12, the guide assembly 50, the telescopic tube assembly 30 and the handle 80 at the various stages of installation are illustrated in Fig. 9 .
  • the auxiliary handle 80 is selectively adjustable by the installer to provide maximum stability and comfort to the installer.
  • the handle locks in place with a pin 85.
  • the handle 80 is initially adjustable.
  • a button 87 is pressed to release the telescoping tube 34 from its fixed relationship with the proximal tube 32 and drive the threaded fastener.
  • the handle 80 essentially remains stationary as the driver moves during the installation progress, as best illustrated in Fig. 9 .
  • the tube 32 retracts relative to tube 34 to accommodate the progressive expelling of the fastener 12 from the fastener chamber 52.
  • the telescoping tubes 32 and 34 only lock when in the fully driven position, at which point, the fastener 12 is fully driven.
  • an automatic locking handle is generally designated by the numeral 90.
  • the handle 90 is generally configured to radially extend from the proximal tube 32 and slide along the tube 32 during the driving process until it automatically locks at the full drive position.

  • the yoke 94 wraps around the tube 32 and is exteriorly slidable therealong.
  • the automatic locking handle 90 is automatically locked by the use of balls 96 which are entrapped in a bearing 98.
  • the driving rod 49 has a varying diameter along a longitudinal portion. As best illustrated in the sequence of Figs. 12A-C , as the fastener 12 is driven, the geometry of the driving rod has reduced diametric surfaces allowing the balls to slip by and the outer distal tube 34 to fully telescope.
  • the external handle can be placed anywhere along the proximal tube 32. It will be appreciated that as the fastener 12 is driven, the handle is rearwardly displaced toward the driver 42 until a fully locked position is obtained and the telescoping tube 34 is retracted.
  • FIG. 110 another handle which may be employed for a third embodiment of a fastener installation tool is generally designated by the numeral 110.
  • the handle 110 includes a circumferential grip 112 which extends around the proximal tube 132.
  • the grip 112 may be easily moved along the base tube 32 and tightened in position or loosened by means of a twisting motion on the grip about the longitudinal axis of the tube assembly 30.
  • a protrusion 114 rides within an internal slot 116 which is attached in fixed relationship to the driver 42.
  • the proximal tube 132 forms the internal slot 116, and the sliding tube 134 includes an external rib 147.
  • the internal slot 116 is not aligned with the rib 147 in the dormant/non-drive state ( Fig. 15A ).
  • the protrusion 114 starts to ride in the internal slot 116 until it changes geometry and twists, thereby causing the handle to twist ( Figs. 15B-C ).
  • the foregoing continues until the second slot is aligned with the external rib, thereby allowing the tube 134 to fully telescope inwardly ( Fig. 15D ).
  • the installer feels the handle 110 rotate slightly, the installer knows that the fastener 12 has been sufficiently initially driven, and the installer can release the grip 112 on the handle and place both hands on the driver 42.

  • the installer merely grips along the tube assembly at a location that appears to be most advantageous.
  • the installation tool 10 is preferably battery powered and includes a chargeable battery power pack.

  • Figs. 16A and 16B two different structural heights of the top plane 22 and two appropriately dimensioned installation tools for relatively tall and short installers (shown in silhouette) are illustrated, it should be appreciated that the dimensioning of the telescopic tube assembly 30, in terms of longitudinal length, is established to accommodate the preferred application in connection with connecting a top plate 22 to a roof support member 26 without the installer needing a ladder or a platform to obtain the correct reach for driving the fastener.
  • the length of the telescopic tube assembly 30 is preferably selected to accommodate a wide range of installers' physical dimensions.
  • an alternative guide assembly may be employed.
  • the effective depth of the fastener channel is altered.
  • the telescopic extremes of the telescopic tubes 32 and 34 are adjusted to accommodate for the driving length for the fastener.
  • the coupler of the installation tool is adapted to complement the head of the fastener.
  • the guide assembly may also be configured so that the fastener channel is at an acute angle relative to the engagement surface at the prescribed optimum angle.
  • the position of the alignment bracket 68 may also be varied in accordance with a specific project. Multiple guide assemblies for various installation angles may be provided and attached to the telescopic tube assembly as desired.
  • the power driver 40 is easily dismounted from the telescopic tube assembly 30.
  • the telescopic tube assembly may employ a receiver configured to receive and functionally attach to a wide range of dismountable drill guns without the torque driver being fully integrated with the telescopic tube assembly.
  • Installation tool 200 includes a receiver 202 for the power driver assembly (not illustrated), a telescopic tube assembly 230 comprising telescopic tubes 232 and 234, and a fastener guide head assembly 250 which is mounted at the end 236 of tube 234.
  • a handle assembly 210 is disposed in longitudinally fixed relationship to tube 234 and includes a trigger 212 which is depressible into one of essentially two positions.
  • One partially depressed position of the trigger 212 allows for the handle assembly to be angularly adjusted about the longitudinal axis of the distal tube 234 at a preset defined angular position.
  • the full depressed position of the trigger 212 allows for the proximal tube 232 to be retracted relative to the distal tube 234 when the fastener 12 is driven.
  • the handle assembly 210 also provides for two-handed support of the tool so that the stabilizing edge 276 can be effectively stabbed into the support member. It should be appreciated that the tubes 232 and 234 do not rotate relative to each other with the non-rotatable position being ensured by a longitudinal flat 236 which engages through the handle assembly.
  • the handle 210 has a grip portion 214 which carries the trigger 212.
  • the handle assembly 210 is attached to the distal tube 234 by a yoke 240 which is longitudinally fixed between a pair of collars 241 and 243.
  • the trigger 212 moves a ramp 216 which engages complementary ramp 218 of a plunger 220.

  • the projectable detent 222 is longitudinally aligned with the recesses 225 and receivable in a selected recess for retention under the plunger bias.
  • the detent 222 Upon depressing the trigger 212, the detent 222 is retracted from a recess 225.
  • Angularly rotating the grip 214 relative to the distal tube 234 allows detent 222 to be angularly engageable into a selected recess 225 to fix the angular position of the handle assembly 210 as desired by the installer. That angular position is further secured by a thumb screw 246 at the top which is tightened to secure the desired angular position.
  • a pair of internal collar mounts 245 and 247 are respectively fixedly mounted interiorly of the tubes 232 and 234.
  • the mounts allow rotational and axial movement of the drive train.
  • a spring 248 bears against the mounts and essentially biases the tubes 232 and 234 to a maximum extended position which is limited by a stop 249.
  • the spring 248 may be optional.
  • Stop 249 allows for replacement of the driver bit 282 to complement the fastener head.
  • the plunger detent 222 also extends through an opening 223 to prevent movement between the distal tube 234 and the proximal tube 232 and thus fix the effective tool length. When the trigger 212 is fully depressed, the plunger is retracted from the opening 223 to allow the proximal tube to move relative to the distal tube against the bias of the spring 248 until the fastener is fully driven.
