A step ladder is designed to hang on an OEM ladder on a recreational vehicle (“RV”) while traveling on the road. The step ladder comprises a hanger bracket to hang the step ladder on the OEM ladder. The bracket is wider than a width of the legs of the step ladder to project over a rung of the OEM ladder. A hook on the bracket grabs the rung of the OEM ladder. The step ladder may be further secured to the OEM ladder by inserting a lock through the bracket and through or adjacent to the rung of the OEM ladder, or by inserting a lock through another rung of the OEM ladder and a retaining tab of the step ladder. A stabilizer attached to the step ladder and the RV can further stabilize the ladder when desired.

A ladder comprises a front leg and a rear leg connected by a slider bracket. The slider bracket comprises a base and a track. The base comprises an aperture therein. The track extends away from the base and comprises a slot therein. The base is rotatably coupled to the front leg by a front pin in the aperture. The track is slidably coupled to the rear leg by a rear pin in the slot. When spreading the rear leg away from the front leg, the base pivots around the front pin as the rear pin slides in the slot of the track until the rear pin reaches the end of the slot in the track. The slot also may include a latch at the end of the slot that engages the rear pin.

The present invention discloses a multifunction ladder structure, it includes a first ladder frame; a second ladder frame; and two combining assemblies that combine the second ladder frame with the first ladder frame, altogether with an optional adjustable band and plural optional foot rods each slides or fixes individually in the first or the second ladder frame. With the implementation of the present invention, the multifunction ladder structure has the special benefit of being easy to install or operate; being able to insert and set firmly in between a tire and the wheel fender as a tire ladder; being able to stand firmly beside a car or places as an A-shaped ladder; with further adding of an adjustable band on the first ladder frame to encircle the tire for even better stability when being used as a tire ladder, or to encircle the second ladder frame for safer storing or transporting; adopting plural foot rods each slides or remains still individually in the first or the second ladder frame, the multifunction ladder structure further applies better on tires of different size, and stands firmly on rough or inclined ground, roads or object surfaces; and with the top rod of the first ladder frame or the further installing of a second stepping unit, the stepping height of the A-shaped ladder can be further raised for even more convenient applications.

A device for the purpose of assisting in the opening and closing of a step ladder. The inventive device is targeted for the safe engaging and disengaging of the spreader lock. The spreader lock of most step ladders requires an upward force to be applied by the operator's hand to the underside of the spreader lock. With the use of this device, the upward force can be applied indirectly and allow for the user's hands to safely remain free of the moving parts of the front rail, rear rail, and spreader.

A step ladder carrier has an enclosure and a ladder securing assembly. The ladder securing assembly has a movable stop having an engaged position in which it engages a first step of a step ladder and having a disengaged position in which it does not engage a first step of a step ladder, the movable stop being moved between the engaged and disengaged positions by an externally accessible handle at the rear wall of the carrier.
