Description

TECHNOLOGY

The present disclosure relates to lift pad links and stabilizing accessories for linking jacks and objects to be lifted.

BACKGROUND

Typical jacks utilize mechanical configurations such as scissors or screws, hydraulics, and compressed air to lift objects. Jacks are available in many configurations such as floor jacks, scissor jacks, bottle jacks, and farm jacks. Jacks that are used to lift objects higher or from a higher position than a typical jack may be referred to as high-lift jacks. These types of jacks are especially useful for raising high frame vehicles, e.g., tall SUVs, vehicles with raised suspensions, or lifted frames. High-lift jacks typically include a vertical I-beam bar having a series of holes. A runner wraps around the I-beam. A foot extends from the runner, horizontally from the post, and includes a lift pad for placing under a bumper or frame. The runner includes a ratcheting mechanism that uses a climbing pin that may be ratcheted with a lever to insert, withdraw, and reinsert into the series of holes to climb the I-beam, raising the lift pad.

DESCRIPTION

The present disclosure describes various embodiments of an improved safety link for a jack that addresses various practical limitations of current safety links for jacks. For example, current high-lift jack adaptors are generally unsecure and unstable and are at risk of slipping out of place while in use.

The present disclosure relates to a safety link (“link”) that may be used with jacks, such as farm jacks, e.g., high-lift or bumper jacks, toe jacks, and other suitable jack configurations. The link may typically be utilized to couple to a lift structure of a jack, which as used herein includes jack structures that are raised by the operation of the jack. For example, lift structures may include lift pads having one or more surfaces upon which an object to be lifted is to be supported during operation of the jack. A high-lift jack, for instance, includes a runner comprising a lift structure, which may also be referred to as a foot or shoe, including a lift pad. Lift structures or lift pads thereof may include planar or contoured engagement surfaces for supporting an object while being lifted by the jack. Some lift pad configurations may also include structures for receiving or engaging a corresponding or mating structure of the object to be lifted.

In various embodiments, the link may be used to secure the jack to a vehicle or other object to be lifted. For example, the link may secure to a mount provided on a vehicle bumper or elsewhere. As introduced above, the link may also secure to a lift structure, such as a runner, of a jack. Thus, according to various embodiments, the link may be configured to connect to a jack, e.g., via connection with a lift structure of the jack, and to an object to be lifted, such as a vehicle. For example, the link is configured to connect to a runner of a high-lift, farm jack style jack and to a shackle tab of a vehicle to be lifted, thereby securing the jack to the vehicle. Beneficially, the link may eliminate certain unsafe hoisting practices such as the common practice of connecting a high-lift jack to a screw pin anchor shackle.

In various embodiments, the link may be utilized as a recovery/safety gear for off-road type vehicles, vehicles with high or raised frames, and/or vehicles with suitable mounting points to which the link may connect. For example, the link may include an upper bracket and a lower bracket wherein the upper bracket is configured to couple to a vehicle shackle tab, such as a shackle tab of an off-road vehicle, and the lower bracket is configured to couple to a lift structure of a jack. The link may be configured to make lifting such a vehicle safer by connecting the jack to the bumper of the vehicle through the shackle tabs. For example, the link may provide a secured connection between the jack and a bumper shackle tab that prevents slippage at the hoisting point, creating a safer lift for the end user. In various embodiments, the safety link may be used in conjunction with a farm jack style high-lift jack, such as Hi-Lift® jacks sold by The Bloomfield Manufacturing Co.

FIG. 15 illustrates an embodiment of a farm or high-lift jack 600, which may be used in conjunction with the safety link 100 described herein. The high-lift jack 600 includes a vertical bar 1000 and a runner 1402 that may be ratcheted up and down the bar. A foot 602 extends from the runner 1402, horizontally from the bar 1000. The foot 602 includes a lift pad 1404 positioned along an upper portion of a runner nose 1400 for placing under a bumper or other vehicle lift point. A slot 604 also extends through the runner nose 1400. In some embodiments, a lower bracket of the link may be connected to the foot 602 and an upper bracket of the link may be connected to the vehicle, e.g., to a shackle tab.

FIGS. 1-14 illustrate various exemplary embodiments and features of a safety link according to various embodiments wherein like numbers refer to like features.

FIG. 14 illustrates an embodiment of a safety link 100 linking a jack 600 to a shackle tab 1204 of a vehicle (not visible) according to various embodiments described herein. As introduced above, the link 100 may include an lower bracket 108 and a upper bracket 102. The lower bracket 108 may be configured to secure the link to a slotted structure such as a shackle tab 1204 or bumper 1206 having a shackle tab 1204 or other slotted structure. One or more openings (not visible) may be provided through one or more plates 105, which may be referred to as vertical plate 105, of the lower bracket 108 to provide a slot (not visible) therethrough. The vertical plate 105 extends generally in the vertical direction. In the illustrated embodiment, a pin 702 is slotted through the shackle tab 1204 and the slot formed by the opening in lower bracket 108 to connect the link 100 to the vehicle via the shackle tab 1204. In some embodiments, a forward edge 107 of the lower bracket 108 may extend a distance from one or more slots of the lower bracket 108 to engage the bumper 1206 structure adjacent to the shackle tab 1204 to prevent or limit rotation of link 100 relative to the vehicle.

The upper bracket 102 also includes one or more slots 110 for connecting to the jack 600 via the runner 1402. The one or more slots 110 may include one or more openings 110a through the upper bracket 102. In the illustrated embodiment, the upper bracket 102 includes two vertically extending plates 111a, 111b, each including an opening 110a (opening in plate 111b is not visible). To secure the jack 600 to the link 100, the runner nose 1400 may be positioned between the openings 110a of the plates 111a, 111b and a pin 700 may be inserted thorough the slot 110 extending therebetween and a slot 604 (see, FIG. 15) in the runner nose 1400.

In the illustrated embodiment, the upper bracket 102 includes a horizontally extending plate 113 or cross-member positioned above slot 110. The horizontal plate 113 may position over the runner nose 1400 when connected to the link 100. The horizontal plate 113 may connect to one or more both vertical plates 111a, 111b of the upper bracket 102. Cotter pins 1200, 1300 may be used to prevent the pins 700, 702 from unintentionally dislodging. In operation, the horizontal plate 113 plate may interface with the lift pad 1404 to provide additional support when connected to the jack 600. In some embodiments, the horizontal plate 113 may not interface with the lift pad 1404 under normal use and may comprise a safety feature in case of pin failure. In another embodiment, the link 100 may not include a horizontal plate 113. In one such example, the link 100 may be configured to connect to a runner nose 1400 comprising a slot having a non-circular cross-section shape or a having a cross-section shape that does not allow rotation of a pin 700. In one such example, the pin 700 has a complimentary cross-section shape to that of the slot. The upper bracket 102 may include one or more slots 110 having a cross-section shape that corresponds to the cross-section shape of the slot in the runner nose 1400 such that, when a pin 700 having a cross-section shape corresponding to that of the openings 110a and the slot in the runner nose 1402 is inserted, the link 100 is prevented from rotating relative to the runner nose 1400. In another example, the link 100 may be configured to connect to a runner nose 1400 comprising multiple slots wherein the upper bracket 102 includes multiple corresponding slots 110 that extend through the vertical plates 111a, 111b between corresponding openings 110a such that multiple pins may be inserted through the upper bracket 102 slots 110 and the slots in the runner nose 1400 to prevent rotation of the runner nose 1400 with respect to the link 100.

As described in more detail below, other link configurations may include multiple vertical plates extending along the upper bracket 102, a horizontal plate extending between two or more of the multiple vertical plates of the upper bracket 102, a horizontal plate extending between the vertical plates 111a, 111b of the lower bracket, and/or a lower bracket extension that in use extends below the foot 602 to position adjacent to the bar 1000 of the jack 600 to provide additional support. In one such example, the link 100 has an L-shape to provide superior stability when in use. In one embodiment, the link includes multiple slots or pairs of slots for securing the link 100 to a shackle tab 1204, which may correspond to different vehicle heights. In the illustrated embodiment, the upper bracket 102 includes a slot and opening (not visible) through plate 105 that is vertically offset from one or more slots 110 and corresponding openings 110a through the lower bracket 108 such that the slot of the upper bracket 102 is forward of one or more slots 110 through the lower bracket 108. In a further or another embodiment, one or more slots in the upper bracket 102 may not be vertically offset from one or more slots 110 through the lower bracket 108 and/or one or more slots 110 through the lower bracket 108 may be vertically offset forward of one or more slots through the upper bracket 102.
