Abstract: A lift mechanism is mounted to a support for raising and lowering a bed. The lift mechanism is attached to a side of the bed and includes at least one chain, at least one bed bracket connected to the chain, and a drive mechanism for controllably moving the chain to move the bed bracket and the bed between a respective raised position and lowered position. The bed bracket includes a chain connector for connecting to the chain, a chain guide member receiving the chain and attached to the chain connector, and a bed support member attaching to the chain guide member and to the bed. At least a portion of the bed support member is inserted through the chain guide member. The bed bracket is compact and easy to manufacture and provides a secure connection between the lift mechanism and the bed.

Abstract: A bed lift mechanism raises and lowers two beds is provided and includes a first lifting assembly attached to one side of the bed including a pair of vertical chains guided by four lifting sprockets, the vertical chains and lifting sprockets disposed in a pair of vertical track members; and a second lifting assembly attached to another side of the bed including a pair of vertical chains guided by four lifting sprockets, the vertical chains and lifting sprockets disposed in a pair of vertical track members. A single drive mechanism transfers rotational motion to the lifting sprockets which are coupled to each other to move synchronously. The bed lift also provides multiple safety mechanisms to prevent the beds from drifting down unintentionally.

Abstract: A bed lift mechanism includes a first gear assembly attached to one side of the bed including a pair of sprockets coupled to a pair of coupling gears that engage with track members mounted to the side wall of the toy trailer; a second gear assembly attached to another side of the bed including another pair of sprockets coupled to a pair of coupling gears that engage with track members mounted to the opposite side wall of the toy trailer. A drive mechanism transfers rotational motion to one of the sprockets in the first gear assembly, the sprockets in the first gear assembly being operatively coupled to each other. The rotational motion is transferred from the first gear assembly to one of the sprockets in the second gear assembly, the sprockets in the second gear assembly being operatively coupled to each other.

Abstract: According to one aspect, a slide-out mechanism for controllably moving a slide-out section that is associated with a vehicle, such as a recreational vehicle, is provided. The slide-out mechanism generally includes a pair of first guide members that are operatively coupled to the slide-out section, with each of the first guide members having a plurality of first drive features formed as a part thereof. The slide-out mechanism also includes a drive mechanism having a pair of first drive members that complement and engage the first drive features for controllably moving the slide-out section between a retracted position and an extended position as the first drive members successively engage the first drive features under action of the drive mechanism, thereby driving the first guide members and the slide-out section coupled thereto.
