Having Supporting Base Patents (Class 182/180.2)
  • Patent number: 8752671
    Abstract: A portable, collapsible, free-standing device for use by a rider to access the saddle stirrup when mounting a horse. The device has a center support pole with a handle on one end and a base on the other. Two folding steps are each pivotally mounted to spaced-apart brackets attached to the pole, to assist the rider to reach the stirrup. Several folding legs are mounted to a collar attached to the center pole in order to stabilize the device. The legs can be configured with extensions so that the device can be leveled on uneven terrain. Pivoting foot pads can be attached onto the ends of the legs. A rope is attached to the handle so that the device can be pulled up after the rider has mounted the horse, whereupon the device can be folded and collapsed for storage on the horse.

  • Patent number: 7328772
    Abstract: Ladder support apparatus and methods are disclosed. In one embodiment, a method includes positioning a ladder having first and second pairs of legs in an operating position suitable for supporting a user. A ladder support assembly clampably coupled to the ladder, the ladder support assembly including at least one elongated member extending between a respective one of the first and second pairs of legs of the ladder, the elongated member being clampably coupled to the respective one of the first and second pairs of legs of the ladder by first and second coupling assemblies positioned at spaced-apart positions on the elongated member. The ladder is supported with the ladder support assembly on, for example, a non-uniform surface.

  • Patent number: 7073629
    Abstract: Ladder support apparatus and methods are disclosed. In one embodiment, a support assembly adapted for use with a ladder includes at least one elongated member adapted to extend between first and second legs of the ladder when the ladder is positioned in an operating position. First and second coupling assemblies are coupled to the elongated member at spaced-apart positions on the elongated member. The first and second coupling assemblies are adapted to be clampably coupled to the first and second legs of the ladder, respectively. The support assembly advantageously permits the ladder to be operated over non-uniform surfaces without permanent modification of the ladder.

  • Patent number: 6902036
    Abstract: A ladder is equipped with a stabilizing device. The stabilizing device resists movements of the ladder's feet which would occur in response to movements of a ladder's user while on the ladder. The stabilizing device holds the ladder's feet and provides transverse and longitudinal structure to provide counter forces to the ladder's feet to hold the ladder's feet against movement. The stabilizing device may have rigid bars forming a box structure extending between the ladder's feet or may be formed as a solid panel. The stabilizing device may be retrofitted to existing ladders.

  • Publication number: 20040144595
    Abstract: A ladder stabiliser 1 comprises a metal frame (2) of substantially A-shape, comprising a pair of ground-engaging legs 3 connected by an upper cross-member (4) and a lower cross-member (5). A retaining bar 6 is mounted at an upper part of the frame (2), and serves to attach the stabiliser 1 to a ladder 10, in use. A pair of hooks 7 are mounted on the lower cross-member (5) and serve to support the lowermost rung 102 of the ladder 10 in use of the stabiliser 1. Each of the legs 3 is of adjustable height and is such that, even in the least extended position of the legs 3, the foot of the ladder 10, represented by the lowermost part of its stiles 101, is maintained clearly above ground level. This ensures that the weight of the ladder 10 is transferred to the ground 20 via the legs 3, rather than the ladder stiles 101, thereby providing a reliably wider support base for the ladder 10.

  • Publication number: 20040140156
    Abstract: Ladder configurations and components are provided including an outer rail assembly which is longitudinally adjustable relative to an inner rail assembly. The outer rail assembly may include a pair of spaced apart outer rails each fixedly coupled to an associated sleeve or sliding mechanism. Each sleeve is in turn slidably couple to an inner rail of the inner rail assembly. The outer rails may be positioned and oriented at an acute angle relative to the inner rails so as to provide an increased base distance between the two outer rails. Support structures are also disclosed which are coupled at multiple locations along a rail member and at least one location of a rung. Additionally, ladder hinges are disclosed including hinge components configured to effectively transmit loads from associated rails. In one embodiment the hinge may include a pinch prevention mechanism.

  • Patent number: 6527084
    Abstract: A ladder stabilizer includes a substantially planar rigid frame having two legs depending in spaced apart relation with a fixed angular relationship to the frame. The frame has a first end and a second end, with remote ends of the two legs defining the second end. A pivot bar is provided which is secured to a selected rung of a ladder. Pivot bar retention brackets are secured to the frame in spaced relation adjacent to the first end. The ladder stabilizer described can be attached to a ladder without drilling bolt apertures.

  • Patent number: 6419047
    Abstract: A ladder is provided which has considerably reduced tendency to slip. Typically, the ladder 1 has rungs 5 and side members 2 with end caps 3 resting on the ground 4. Securing member 6, made typically from aluminium alloy, has friction member 7 provided with spikes 16. Pivot member 8 on the securing member 6 is fixed at one end on the securing member to opposite sides of the securing member, and at the other end is mounted through bolt 9 to the side member of the ladder. Flat spring 17 is fitted around the bolts 9, the spring being biassed to bring the securing member 6 against the side member 2. The pivot member is arcuate in shape to allow the securing member, when not in use to be positioned essentially flat against the ladder and not proud of the lower end of the side member. In use, the ladder is placed on the ground and against a wall. The securing member is pivoted against the bias of spring 17 so as to place it on the ground.
