The present disclosure relates generally to frame racks, and more specifically, to an apparatus to couple a hydraulic ram to a frame deck.
This section provides background information related to the present disclosure which is not necessarily prior art.
Frame racks are typically used to straighten the frame of an automotive vehicle after a collision. A frame rack has a deck onto which the vehicle is placed. A number of towers are positioned around the frame rack. The towers have a chain connected thereto that is coupled to a ram. The chains are connected to the frame of the vehicle and the tower is used to pull the chain toward the tower. Typically, the chains are connected to the vehicle so that the vehicle frame is pulled out in the same direction of impact. When the pulling of the frame begins, it is often necessary to adjust the direction of pulling so the pulling force remains in the direction of impact. Oftentimes, this requires the tension to be released from the vehicle, the tower position to be adjusted, and tension placed on the vehicle frame in a slightly different direction. This, however, is a time consuming process and thus increases the expense of the collision repair.
To place tension on the vehicle in a slightly different direction, a separate hydraulic ram is sometimes coupled to a frame deck. The hydraulic ram may provide push/pull capabilities. Because a tower may not be available, a portable hydraulic ram may be used. The portable hydraulic ram is typically coupled to the frame deck using hooks. One problem with using a hook is that the frame deck is typically formed of a sheet of steel material, commonly 0.5″ thick. Although the thickness is substantial, the frame deck may easily be bent when localized pulling on the order of thousands or even tens of thousands of pounds takes place during a straightening operation. If the frame rack is damaged, expensive repairs may be required to be performed. This may result in lost time and thus revenue for the frame rack operator.
It would therefore be desirable to provide a system for allowing flexibility in the frame straightening process and reduce potential damage to frame racks. Also, it is desirable to allow pulling at various angles with respect to the deck.
This section provides a general summary of the disclosure, and is not a comprehensive disclosure of its full scope or all of its features.
The present disclosure provides a system suitable for use with a hydraulic actuator that can be easily maneuvered and positioned on a deck such as a deck of a frame rack.
A deck anchor assembly for anchoring a frame loading member to a frame deck according to the principles of the present disclosure may include a deck leverage anchor and a coupler. The deck leverage anchor is configured to engage the frame deck, the deck leverage anchor including a locking mechanism configured to lock the deck leverage anchor relative to the frame deck. The coupler is configured to couple the frame loading member to the deck leverage anchor and is independently movable relative to the locking mechanism.
A deck anchor assembly for anchoring a frame loading member to a frame deck according to the principles of the present disclosure may include a first plate, a base, a second plate, a locking mechanism, and a coupler. The first plate is configured to engage a first surface of the frame deck when the deck anchor assembly is disposed within an opening in the frame deck. The base is attached to the first plate and configured to engage the opening in the frame deck when the first plate engages the first surface of the frame deck. The second plate is coupled to and spaced apart from the first plate. The second plate is configured to engage a second surface of the frame deck that is opposite from the first surface when the first plate engages the first surface of the frame deck.
The locking mechanism is configured to lock the deck anchor assembly relative to the frame deck when the deck anchor assembly is disposed within the opening in the frame deck. The coupler is configured to couple the frame loading member to the first plate. The coupler is independently movable relative to the locking mechanism.

As illustrated, two hoses 20A and 20B, fluidly couple directional converter 16 and hydraulic actuator 14. Also, two hoses 22A and 22B fluidly couple directional converter 16 and pump 18. Hydraulic actuator 14 may have a mechanical coupling device such as a pair of claw hooks 24. It should be noted that in various applications claw hooks 24 may be substituted with other mechanical fastening devices such as bolt down components, loops, stays, or a deck leverage anchor 40 according to the present disclosure. Claw hook 24 is illustrated mechanically coupled to a chain 26, which in turn is coupled to a portion of a frame 28 of an automotive vehicle.
Frame rack 12 may also include various towers 34 that include a guide 36 and a chain 38. Of course, different numbers of towers 34 may be used on a frame rack. A support 33 may be used to support the vehicle. Frame rack 12 has a deck 30 for positioning a vehicle thereon. Deck 30 may have openings 32 or tie down holes positioned therethrough. Deck leverage anchor 40 may be secured at least partially within one of the openings 32.
Referring now to
Deck leverage anchor 40 includes an upper plate 41, a lower plate 42, and a swivel plate 43 that swivels with respect to the lower plate 42. The upper plate 41 and the lower plate 42 may be vertically spaced apart and connected to each other using spacers or risers, as discussed below.
Deck leverage anchor 40 may be inserted into the opening 32 such that the upper plate 41 engages or rests on the first surface 30A and a flange 44 on the lower plate 42 engages the second surface 30B. The upper plate 41 and the lower plate 42 of deck leverage anchor 40 may be parallel to the upper plate 31A and the lower plate 32A of deck 30. The profile of the lower plate 42 may be sized to fit within the opening 32 to allow insertion of deck leverage anchor 40 into the opening. As discussed below, the swivel plate 43 may then be rotated from an unlocked position to a lock position such that the swivel plate 43 engages the second surface 30B. In the lock position, opposite ends of deck leverage anchor 40 engage the second surface 30B. As a result, deck leverage anchor 40 is locked in place relative to deck 30. In this regard, the swivel plate 43 and components used to rotate and/or retain the swivel plate 43 may be collectively referred to as a locking mechanism. The components used to rotate the swivel plate 43 may include a lever disposed above deck 30 and components that couple the lever to the swivel plate 43 such that the locking mechanism is accessible in an area other than under deck 30.
Hydraulic actuator 14 is coupled to deck 30 using an actuator coupler 45. Actuator coupler 45 couples hydraulic actuator 14 to deck leverage anchor 40. As discussed in more detail below, actuator coupler 45 may be rotated with respect to deck leverage anchor 40 and independent from the swivel plate 43.
A pulley 46 may also be coupled to deck 30. Pulley 46 may be coupled to deck 30 using a pulley coupler 48. Pulley coupler 48 couples pulley 46 to deck leverage anchor 40. As discussed in more detail below, pulley coupler 48 may be rotated with respect to deck leverage anchor 40 and independent from the swivel plate 43. The hydraulic actuator 14 and the pulley 46 may be referred to as frame loading members, as the hydraulic actuator 14 and the pulley 46 are used to apply a load on a vehicle frame.

The flange 44 of the lower plate 42 includes a ramped surface 52. The ramped surface 52 of the flange 44 inhibits contact between the flange 44 and the deck 30 when the flange 44 is positioned below the second surface 30B. This facilitates insertion of deck leverage anchor 40 into the opening 32.
Referring now to
A base 64 may be formed (e.g., machined) integrally with the upper plate 41. Alternatively, the base 64 and the upper plate 41 may be formed separately and attached together. The flange 50 on the upper plate 41 is the portion of the upper plate 41 that extends beyond the perimeter of the base 64. The base 64 may be sized to fit within and engage the opening 32 in the deck 30.
Risers 66 couple and space apart the upper plate 41 and the lower plate 42. The risers 66 may be c-channels, as shown, and may be spaced apart and/or parallel to one another. In addition, the risers 66 may be parallel to the axis 63 and/or the insertion direction of the bolts 60 and/or the bolt 62. The heights of the risers 66 may be selected to ensure that the swivel plate 43 may be rotated into engagement with the second surface 30B when the upper plate 41 is resting on the first surface 30A, as discussed above. The longitudinal ends of the risers 66 are attached (e.g., welded) to the base 64 and the lower plate 42.
Cross members or gussets 68 extend between the risers 66. The gussets 68 may increase the stiffness and/or strength of deck leverage anchor 40. The gussets 68 may have a generally parallelogram shape. The longitudinal ends of the gussets 68 are attached (e.g., welded) to the risers 66.
The lower plate 42 defines a first hole 70, a second hole 72, and a third hole 74, as best shown in
The lower plate 42 also defines recessed surfaces 78 and the base 64 defines recessed surfaces 80, as best shown in
The bolt 60 extends through the first hole 54 in the upper plate 41 and through the first hole 70 in the lower plate 42. The bolt 60 couples a lever 82 to a cam 84 and the cam 84 engages the swivel plate 43 such that the swivel plate 43 rotates with the lever 82 between the unlocked position and the locked position, as described in more detail below. The bolt 60 extends through a hole 86 in the lever 82. The lever 82 and the cam 84 are attached to the bolt 60. For example, the lever 82 may be welded to the bolt 60, and the bolt 60 may be threaded into a hole 88 in the cam 84. A portion of the lever 82 may be captured between the head of the bolt 60 and a recessed surface 90 in the upper plate 41. At least a portion of the lever 82 may rotate within a plane that is parallel to the recessed surface 90 in the upper plate 41 and the surfaces 30A, 30B on deck 30. In addition, the lever 82 may rotate within a plane that is perpendicular to the axis 61, the axis 63, the axis 65, the risers 66 and/or the axis 77.
The lower plate 42 further defines a first surface 91a and a second surface 91b. The first surface 91a engages the lever 82 when the lever 82 is in the unlocked position, as best shown in
The bolt 62 extends through the third hole 58 in the upper plate 41 and extends at least partially through the third hole 74 in the lower plate 42. The bolt 62 couples the upper plate 41 and the lower plate 42. The bolt 62 may be used to couple the upper plate 41 and the lower plate 42 before the risers 66 are attached to the base 64 and the lower plate 42. In addition, the bolt 62 may be used to increase the strength of the connection between the upper plate 41 and the lower plate 42.
The swivel plate 43 defines a first hole 92, a channel 94, and a second hole 96, as best shown in
The lower plate 42 further defines a groove 102, an unlock detent 104, a lock detent 106, a first surface 108, and a second surface 110, as best shown in
The channel 94 in the swivel plate 43 may define an unlock detent 112 and a lock detent 114, as best shown in
With continued reference to
In addition, in the unlocked position, the ball plunger 100 engages the unlock detent 104 in the lower plate 42, as best shown in
Deck leverage anchor 40 is inserted into the opening 32 in deck 30 as discussed above with reference to
In the locked position, the perimeter of the swivel plate 43 extends beyond the perimeter of the opening 32 in deck 30, as best shown in
In addition, in the locked position, the ball plunger 100 engages the lock detent 106 in the lower plate 42, as best shown in
To remove deck leverage anchor 40 from the opening 32 in deck 30, the lever 82 may be rotated from the locked position to the unlocked position. The first surface 91a of the upper plate 41 may act as a stop for the lever 82 and the first surface 108 may act as a stop for the swivel plate 43 as the lever 82 is rotated to the unlocked position. The second surface 91b of the upper plate 41 may act as a stop for the lever 82 and the second surface 110 may act as a stop for the swivel plate 43 as the lever 82 is rotated to the locked position.
Referring now to
The extensions 118 define holes 124 configured to receive the fastener 49, as best shown in
The shaft 122 extends through the second hole 56 in the upper plate 41 and the actuator coupler 45 freely rotates about the shaft 122 without restriction. The shaft 122 may include a bearing portion 124 and a threaded portion 126, as best shown in
With continue reference to
Notably, rotating the swivel plate 43 does not rotate the actuator coupler 45, as the actuator coupler 45 and the swivel plate 43 rotate independently. Thus, the actuator coupler 45 may be repositioned (e.g., rotated) without unlocking deck leverage anchor 40 from deck 30. This saves time and thus increases revenue for the frame rack operator. In addition, the lever 82 rotates about the center of the bolt 60, the swivel plate 43 rotates about the center of the fastener 76, and the actuator coupler 45 rotates about the center of the shaft 122. Thus, the rotational axes of the swivel plate 43, the actuator coupler 45, and the lever 82 are offset relative to one another.
Referring now to
The pulley coupler 48 includes extensions 118′. The heights of the extensions 118′ on the pulley coupler 48 may be greater than the heights of the extensions 118 on the actuator coupler 45 to accommodate the outer diameter of the pulley 46 and/or a chain engaging the pulley 46. In addition, the space between the extensions 118′ on the pulley coupler 48 may be respectively greater than the heights of the extensions 118 and the space between the extensions 118 to accommodate the width of the pulley 46.
Operation of the deck anchor assembly 132 may be substantially similar to or identical to operation of the deck anchor assembly 116.
