Description

BACKGROUND

Methods and systems for fastening components, such as bed foundations, are shown and described.

Generally, a bed foundation F includes first and second end rails E, first and second side rails R extending generally perpendicularly between opposite ends of end rails E, a center support C extending between first and second end rails E and spaced from and intermediate side rails R, and a plurality of cross slats S extending between first and second end rails E in a spaced, parallel relation.

It should be appreciated that bed foundations F come in different sizes of different lengths, widths, and heights. Thus, a need exists for methods and systems for fastening which minimize and reduce complexity of human involvement and which also are easily adjustable to allow fastening of components of different sizes.

SUMMARY

This need and other problems in the field of fastening components are solved by providing illustrative embodiments of methods and systems for fastening bed foundations. Specifically, a fastening system generally includes a fixture mounted on a frame, with the fixture adapted to hold a component to be fastened. In some aspects, the fixture includes squaring corners extending to a height above the frame. A nail gun carriage is moveably mounted to the frame and movable between a first position extensive with the fixture and a second position beyond the fixture. A nail gun is carried by the nail gun carriage and, in some aspects, at a consistent height relative to the frame and greater than the fixture height.

In certain aspects, an adjustable spacer is mounted on the frame and has an adjustable height intermediate the fixture height and the frame and adapted to abut the component held in the fixture. In particular, the adjustable spacer is positioned on the frame when adjusted to one of multiple extents corresponding to a depth of the component held in the fixture. Particularly, a body of a fixed shaped but having a height, a width, and a length of different extents can be oriented to have a different face abut with the frame and an opposing face abut with the component. Similarly, pillars are slideable, shown as being telescopic relative to each other, and connected to each other to define multiple extents, with the pillars having an extent corresponding to the component held in the fixture abutting with the frame.

In other aspects, the fixture is in the form of first and second support beams moveably supported between first and second side braces of the frame. First and second slide bars located intermediate and parallel to the first and second support beams are movably mounted to the first and second support beams and moveable relative to the first and second support beams. After being fastened, the component can be lifted from the first and second support beams by raising the first and second slide bars relative to the first and second support beams. The first and second support beams are moved, and can be simultaneously moved, relative to the first and second side braces of the frame to correspond to the component being fastened, with the first and second slide bars moving with the first and second support beams. Particularly, in one aspect, rotating an adjustment shaft threadably engaged in the first and second support beams having linear bearings slideably receiving linear bearing shafts extending between the first and second support braces moves the first and second support beams and the first and second slide bars mounted thereto.

In related aspects, the slide bars are moved by first and second links pivotably mounted together about an axis intermediate first and second ends of the links. The first ends of the first and second links are pivotably connected to opposite ends of the slide bars. The second end of the first link is pivotably mounted to a slide mechanism mounted to the support beam, while the second end of the second link is pivotably mounted to the support beam opposite to the slide mechanism. The first and second links are pivoted by a cylinder, which could be a three position cylinder, having ends connected to the first and second links.

In other aspects, the carriage includes wheels rotatably mounted to inner vertical edges of first and second platforms and received between first and second legs of U-shaped channels of the frame, for movably mounting the carriage to the frame. The nail gun is carried by and between vertical posts upstanding from the first and second platforms. Cables connected to the nail gun are carried by a flexible cable carrier having a C-shaped portion extending from a hanger connected to the platform opposite to the vertical post and an elongated portion parallel to the frame. The distance of the C-shaped portion from the hanger changes with movement of the platform relative to the frame. The carriage is moved by moving first and second endless belts clamped to the first and second platforms, with the platform being intermediate the endless belt and the hanger. An air reservoir can extend between the vertical posts of the first and second platforms providing rigidity and for supplying air to the nail gun.

In other aspects, a plunger is slideably biased towards and engages an outer circumference of a belt drum carrying a spool of fasteners. The heads of nails in a belt are received between a flat board extending tangentially to the cylindrical outer surface of a roller and a bottom of a circumferential V-shaped groove in the cylindrical outer surface of the roller, such that the flat board provides a stationary contact plane for the nails.

In still other aspects, the nail gun, includes a mount movably supported by a linear bearing slideably receiving a linear bearing shaft extending between the vertical posts of the first and second platforms. The nail gun is moved by rotating an adjustment shaft rotatably mounted between the vertical posts and threadably mounted to the mount.

DESCRIPTION OF THE ILLUSTRATIVE EMBODIMENTS

A system for fastening bed foundations F is shown in the drawings and generally designated 10. Generally, system 10 includes a system frame 12 including first and second braces shown as side tubes 14, first and second end tubes 16 extending generally perpendicularly between opposite ends of side tubes 14, and pedestals 18.

System 10 generally includes a fixture 20 extending to a fixture height above system frame 12 for holding components to be fastened, and, in the form shown, bed foundations F. Generally, fixture 20 includes linear bearing shafts 22 extending generally perpendicularly between side tubes 14 of system frame 12 in a spaced parallel relation. First and second support beams 24a are movably supported by linear bearings 26 slideably receiving linear bearing shafts 22. A center support beam 24b is located intermediate and equally spaced between support beams 24a and extends between and is fixed to end tubes 16. Support beams 24a are driven to simultaneously move toward and away from support beam 24b. In the illustrated form, adjustment shafts 28 are rotatably mounted between side tubes 14 and are threadably engaged in support beams 24a. Thus, rotating adjustment shafts 28 in one direction causes support beams 24a to move away from each other and from support beam 24b, and rotating shafts 28 in the opposite direction causes support beams 24a to move toward each other and toward support beam 24b. Suitable provisions such as a drive chain can be provided so that rotation of one adjustment shaft 28 causes an equal amount of rotation of the other adjustment shaft 28.

Fixture 20 further includes compression squaring corners 30 at opposites ends of support beams 24a for slideably receiving the corners of the component to be fastened, and, in the form shown, between side rails R and end rails E of bed foundation F. Squaring elements 32 are also located at opposite ends of support beam 24b for receiving end rails E of bed foundation F. In the illustrated form, squaring corners 30 and squaring elements 32 at one end of fixture 20 are adjustably, slideably mounted to support beams 24a and 24b to allow adjustment to match the longitudinal length of bed foundation F. Fixture 20 further includes adjustable spacers shown as depth control elements 34 located on support beams 24a and 24b intermediate and spaced from squaring corners 30 and squaring elements 32 and having an adjustable height or extent when located on support beams 24a and 24b intermediate the fixture height and frame 12 to correspond to the depth of and to abut with bed foundation F held in fixture 20. In the form illustrated, depth control elements 34 can be connected to support beams 24a and 24b in different orientations corresponding to the height of side and center rails R and C of bed foundation F. Particularly, depth control elements 34 are shown being of a right parallelepiped in shape including a front and back of a rectangular shape having a length and height with a first securement aperture 34a extending therebetween, first and second ends of a rectangular shape having the length and a width with a second securement aperture 34b extending therebetween, and a top or first side and a bottom or second side of a rectangular shape having the length and the width with a third securement aperture 32c extending therebetween. The length is greater than the height which is greater than the width. Thus, by abutting the bottom, one end, or the front with support bars 24a, the upper surface of depth control element 34 will have a different spacing from support bars 24a.

Slat locators 36 are removably connected between squaring corners 30 of each support beam 24a. Suitable provisions for removably connecting slat locators 36 are provided to allow interchanging slat locators 36 to the particular longitudinal length of bed foundation F and/or the number and positioning of slats S in bed foundation F.

Fixture 20 further includes a lift mechanism 40 providing first and second slide bars 42 each terminating in a sloped exit 42a, with first and second slide bars 42 moveable between a fastening position at or below the fixture height and a lifting position greater than the fixture height for lifting and raising bed foundation F after being fastened from fixture 20. In the form illustrated, a first link 44 has a first end pivotably connected to and adjacent a first end of slide bar 42 and second end slideably mounted to support beam 24a by a slide mechanism 46. A second link 48 has a first end pivotably connected adjacent a rear end of slide bar 42 and second end pivotably mounted to a respective support beam 24a by a shaft 50 extending between and connected to the second ends of second links 48 for slide bars 42 and suitably rotatably mounted in support beams 24a. First and second links 44 and 46 are pivotably mounted together about an axis A.

Suitable provisions are provided for pivoting links 44 and 46 relative to each other. In the form illustrated, a pneumatic, three position, cylinder 52 has its outer piston end pivotably mounted to link 44 about axis 52a and has its cylinder portion pivotably mounted to link 48 about axis 52b. In particular, cylinder 52 includes an inner piston 52a movable in a first chamber 52b and an outer piston 52c movable in a second chamber 52d in linear alignment with piston 52a. Piston 52a includes outer piston end pivotably mounted to link 44. Thus, when pistons 52a and 52c were both retracted, outer piston end is in a retracted position. When piston 52a is actuated, piston 52a will abut and push piston 52c to extend for a distance corresponding to the linear length of first chamber 52b. When piston 52c is actuated, piston 52c will extend for a distance corresponding to the linear length of second chamber 52d. In the form shown, first chamber 52b has a linear length shorter than second chamber 52d.

In the form illustrated, link 48 includes a channel 48a having upper and lower openings. First link 44 and axis A extend through channel 48a, with axis 52b extending through channel 48a spaced from axis A and located intermediate the ends of the cylinder portion of hydraulic cylinder 52. Thus, expansion or retraction of pneumatic cylinder 52 causes links 44 and 48 to pivot relative to one another, with the second end of second link 48 rotating relative to support beam 24a and the second end of first link 44 sliding relative to support beam 24a, to raise or lower slide beams 42 relative to squaring corners and elements 30 and 32, depth control elements 34 and slat locators 36. It should also be appreciated that since lift mechanism 40 is mounted to support beams 24a, adjustment of the spacing between slide bars 42 is simultaneously adjusted when support beams 24a are adjusted utilizing adjustment shafts 28.

In an alternate form, adjustable spacers shown as depth control elements 340 can be connected to support beams 24a and 24b by suitable fasteners 342. Particularly, depth control elements 340 include first, second, and third pillars shown as cylindrical components 344, 346 and 348 shown as having annular and, in particular, circular cross sections, with component 346 slideably and telescopically received in component 344 and with component 348 slideably and telescopically received in component 346. Component 344 includes an open top and a closed bottom through which fastener 342 extends. Sets of slots 344a and 344b extend axially from the top edge of component 344, with each set extending to the same depth but different than the other set. Component 346 includes open first and second ends, with sets of slots 346 and 346b extending axially from the second end and with a set of slots 346c extending axially from the first end, with each set extending to the same depth but different than the other set. The outer circumference of component 346 includes spaced, parallel, annular indents 350. Component 346 further includes a set of protrusions 352 threadably received and extending radially outwardly to a radial extent generally equal to the radial extent of component 344. Component 348 includes open first and second ends and spaced, parallel, annular indents 354 on its outer circumference. Component 348 further includes a set of protrusions 356 threadably received and extending radially outwardly to a radial extent generally equal to the radial extent of component 346. Protrusions 352 and 356 have circumferential spacings corresponding to and for receipt in slots 344a and 344b and slots 346a, 346b and 346c. Additionally, component 346 is slideably received in component 344 with either the first or second end facing the closed end of component 344, and component 348 is slideably received in component 346 with either the first or second end facing the closed end of component 344. Thus, if protrusions 352 having an axial extent from the first end of component 346 equal to and for receipt the axial depth of slots 344b with the second end closest to the closed end of component 344 and if protrusions 356 having an axial extent from the first end of component 348 equal to and for receipt in slots 346c with the second end closest to the closed end of component 344, the combined height as shown in FIG. 5A of depth control element 340 is equal to that of component 344. Similarly, if protrusion 352 is received in slots 344a with the second end closest to the closed end of component 344 and if protrusions 356 having an axial extent from the first end of component 348 equal to and for receipt in slots 346c with the second end closest to the closed end of component 344, the combined height as shown in FIG. 5B of depth control element 340 is greater than that of component 344. If protrusions 352 are received in slots 344b with the first end closest to the closed end of component 344 and if protrusions 356 having an axial extent from the first end of component 348 equal to and for receipt in slots 346a with the second end closest to the closed end of component 344, the combined height of depth control element 340 as shown in FIG. 5C is greater than that of FIG. 5B. If protrusions 352 are received in slots 344b with the second end closest to the closed end of component 344 and if protrusions 356 are received in slots 346a with the first end closest to the closed end of component 344, the combined height of depth control element 340 as shown in FIG. 5D is greater than that of FIG. 5C. If protrusions 352 are received in slots 344b with the first end closest to the closed end of component 344 and if protrusions 356 are located in slots 346b with the first end closest to the closed end of component 344, the combined height of depth control element 340 as shown in FIG. 5E is greater than that of FIG. 5D. If protrusions 352 are received in slots 344b with the first end closest to the closed end of component 344d and if protrusions 356 are received in slots 346a with the first end closest to the closed end of component 344d, the combined height of depth control element 340 as shown in FIG. 5F is greater than that of FIG. 5E.

System 10 further includes a nail gun carriage 60 movably mounted to and along side tubes 14 of system frame 12 and moveable between a first position extensive with fixture 20 and a second position beyond fixture 20. Carriage 60 includes first and second vertical posts 62 extending generally perpendicular to system frame 12 with a hollow air reservoir 64 interconnected therebetween spaced from and parallel to system frame 12. Carriage 60 further includes first and second linear bearing shafts 66 extending generally perpendicularly between vertical posts 62 in a spaced parallel relation. Mounts 68 are movably supported by linear bearings 70 slideably receiving linear bearing shafts 66. Mounts 68 on the respective linear bearing shafts 66 are driven to simultaneously move toward and away from vertical posts 62. In the illustrated form, first and second adjustment shafts 72 are rotatably mounted between posts 62 and are threadably mounted to corresponding mounts 68. Thus, rotating adjustment shafts 72 in one direction causes mounts 68 to move toward each other and away from posts 62, and rotating adjustment shafts 72 in an opposite direction causes mounts 68 to move away from each other and toward posts 62.

A nail gun assembly 74 is carried by and between vertical posts 62 by being slideably mounted to each mount 68 and in the form shown at a consistent height relative to system frame 12 when moving in and between the first and second positions. In the form shown, assembly 74 includes a conventional nail gun 76 which is suitably mounted in a holder 78 having a skid plate 80. Skid plate 80 includes a center portion 80a which is generally planar and parallel to system frame 12 and through which nails pass from nail gun 76. Wing portions 80b extend at a small acute angle in the order of 15 degrees and on opposite ends of center portion 80a. A roller 82 is rotatably mounted relative to one wing portion 80b about an axis perpendicular to wing portion 80b and a small acute angle in the order of 2.1 degrees from vertical. A further roller 84 is mounted to the outward end of an arm 86 projecting from holder 78. In the form shown, roller 82 includes a circumferential V-shaped groove 88 extending radially inward of a cylindrical outer surface 82a thereof. Roller 82 is mounted to a U-shaped roller bracket 182 including a first leg 182a suitably secured to arm 86 intermediate and spaced from roller 84 and holder 78. Roller 82 is rotatably mounted about an axis to a tab in the form of a second leg 182b integrally extending from first leg 182a in the same direction away from arm 86 as roller 84. A flat board shown in the form of a third leg 182c integrally extends downward from second leg 182b generally parallel and tangential to but spaced from outer surface 82a, with the distance between third leg 182c and the bottom of V-shaped groove 88 being generally equal to and for receiving a head of a nail to be driven by nail gun 76 when the shank of the nail extends between outer surface 82a and third leg 182c. It should be appreciated that third leg 182c provides a stationary, metal-to-metal, plane of contact for the nails as opposed to a line of contact which would be provided by a pair of rollers to hold and guide the nails to nail gun 76. Roller 82 is located intermediate and spaced from roller 84 and center portion 80a in a direction parallel to system frame 12. Roller 84 is rotatably mounted about an axis at an obtuse angle in the order of 139 degrees to vertical away from system frame 12 and at an acute in the order of 63 degrees away from linear bearing shafts 66.

A support plate 90 is suitably connected to mount 68 such as by fasteners 92. Slide shafts 94 are mounted vertically in a spaced parallel relation to support plate 90 by spaced parallel brackets 96 suitably secured to support plate 90. Holder 78 is suitably slideably mounted to support plate 90 and slide shafts 94 such as by brackets 98 located intermediate brackets 96 and through which slide shafts 94 slideably pass. A reel support 100 is suitably secured such as to support plate 90 and extends in a plane extending generally perpendicular to linear bearing shafts 66 at an acute angle of 15 degrees from vertical and slide shafts 94 and at an obtuse angle of 105 degrees from horizontal and linear bearing shafts 66. A reel axis shaft 102 extends at an acute angle in the order of 15 degrees to horizontal and center portion 80 and to system frame 12 in a plane extending parallel to linear bearing shafts 66. Reel axis shaft 102 extends at an acute angle in the order of 30 degrees to roller 84. Reel axis shaft 102 is intermediate rollers 82 and 84 in a direction parallel to system frame 12, and roller 84 is intermediate roller 82 and reel axis shaft 102 in a direction perpendicular to system frame 12. A nail belt drum 104 is rotatably mounted to reel axis shaft 102 to which tension is applied by a tensioner 106. In particular, tensioner 106 includes a plunger 106a which is slideably biased to a body 106b towards and engaging with an outer circumference of nail belt drum 104. The bias of plunger 106a is adjustable to require a tensional force by the nail belt of a spool of nails carried by the nail belt drum 104 to result in rotation and unwinding of the spool of nails.

Each vertical post 62 upstands from a platform 110 adjacent to its outer vertical edge and which is generally parallel to and outside of system frame 12. First and second support wheels 112 are rotatably mounted to an inner vertical edge of platform 110 about axes parallel to system frame 12 and generally perpendicular to side tubes 14 thereof. Wheels 112 are received in a U-shaped channel 114 suitably secured to system frame 12 with the legs thereof parallel to system frame 12 and the interconnecting portion thereof facing pedestals 18. Hard stops 116 can be secured to system frame 12 and extend over the ends of U-shaped channel 114 to prevent support wheels 112 from leaving U-shaped channel 114 in directions parallel to side tubes 14. The rigidity of posts 62 and hollow air reservoir 64 in fluid communication with nail guns 76 and linear bearing shafts 66 secured therebetween prevent support wheels 112 from moving outwardly of U-shaped channel 114 in a direction perpendicular to side tubes 14. Thus, carriage 60 is movably mounted to system frame 12 and relative to fixture 20 for movement in a direction parallel to side tubes 14.

Suitable provisions are provided for moving carriage 60 relative to system frame 12. In the form shown, first and second endless belts 118 extend between pulleys 120 of first and second shafts 122 adjacent end tubes 16 of system frame 12. One shaft 122 is driven by an electric motor 124 such as by a belt 126 extending around a pulley 128 secured to shaft 122. Belts 118 are secured to carriage 60 shown as being clamped by sandwich type clamps 130 mounted to platform 110. Thus, as shaft 122 is driven by electric motor 124, belts 118 are driven with carriage 60 moving with belts 118 due to the securement by clamps 130. One end of a flexible cable carrier 132 is secured to a hanger 134 secured to platform 110 opposite to clamps 130 and vertical posts 62. Carrier 132 extends from hanger 134 rearwardly away from fixture 20 to a C-shaped portion and then to an elongated portion parallel to the side frame 14 to an opposite end connected to system frame 12, with the distance of hanger 134 to the C-shaped portion increasing as carriage 60 moves towards sloped exit 42a of slide bars 42. Carrier 132 can be any conventional design for containing air and/or electrical feed lines. It should be appreciated that carriage 60 allows mounting of belts 126 and flexible carrier 132 generally in a vertically spaced relation on opposite sides of platform 110 with the belt 126 and the center of flexible carrier located laterally outward of wheels 116 and laterally inward of posts 62 allowing the longitudinal length of carriage 60 to be reduced as well as insuring that posts 62 remain vertical relative to system frame 12.

Fastening system 10 as shown and described includes several aspects which are believed to produce synergistic results especially in connection with fastening bed foundations F. However, it should be appreciated that some or all aspects of fastening system 10 has application to fastening other types and forms of components. Furthermore, it should be appreciated that some or all aspects of fastening system 10 can be used solely or in other combinations than described in similar or other types of fastening systems. Additionally, although fasteners are shown as being nails, fastening system 10 can be utilized with other types of fasteners, such as, but not limited to, staples, and nail guns referenced to herein, should be considered any type of device which drives or installs the particular type of fastener being utilized.
