Abstract: A central tube has a rectangular cross section and is attached to an end piece which abuts against a wall of a compartment or the side of an object to be held in place. The other end of the central tube is telescopically fitted within a second rectangular tube. One surface of the central tube is ratcheted and a handle operated ratchet drive mechanism is mounted on the end of the second tube towards the end piece. The second tube is telescopically fitted within a third tube having a rectangular cross section. The remote end of the third tube is fixedly attached to a second end piece which abuts against either a compartment wall or an object to be held in place. The second tube is joined to the third tube at any one of three extension positions of the third bar relative to the second bar thereby setting the jack bar at a predetermined length. This length can then be increased to hold the cargo in position by actuating the ratchet mechanism.

Abstract: A locking device installed in a cargo support to lock a retractable tube, including a holder frame fastened to the outer tube of the retractable tube, a rack moved in a longitudinal sliding way defined between two parallel lugs of the holder frame, a driving lever pivoted to the holder frame for moving the rack, and a locking block pivoted to the holder frame and retained by a spring to lock the driving lever, wherein a L-shaped locating plate is mounted in the holder frame for the positioning of the outer tube of the retractable tube, having a round hole on a transverse section thereof through which the inner tube is inserted into the outer tube, two stop flanges bilaterally extended from a longitudinal section thereof and respectively engaged with respective end notches on the holder frame, and a lug extended from one stop flange and fastened to a lug at the holder frame; the holder frame and the locking block are respectively made of iron.

Abstract: A window opener is provided. In one embodiment the window opener may include a handle of predetermined width and length, the handle having a grabbing tip and a pivot pin. The window opener may also include a pole, repositionable with respect to the handle, wherein the pole has a first end, a second end, and a cleat in physical communication with the pivot pin. In another embodiment a method of sliding a stuck window within a window frame having a sash is provided. This method may include providing a handle having a proximate end, a distal end, and an opening with a pivot point. It also may include inserting a rigid pole having a plurality of cleats through the opening of the handle, aligning the cleat of the rigid pole with the pivot point of the handle, and applying force to the stuck window section by pivoting the handle in the cleat.

Abstract: The invention relates to a support for articles such as ceiling slabs, roof battens, machine parts or the like. The support comprises at least two telescopic tubes or one telescopic eod in at least one tube. A first tube or the rod can be displaced by a first distance in relation to the second tube, and devices are provided to convey the first tube or the rod a further distance in relation to the second tube. Stopping devices for the tube(s) and the rod are also provided in relation to each other and end stops are provided on the tubes, or the rod, the devices for further conveyance of the first tube or the rod comprising a ratchet, rack, clamping bracket or the like which are provided with manual advance devices.

Abstract: A lifting device particularly suitable for snowmobiles includes a frame with ground engaging feet, a lever pivotally mounted on the frame and connected to a load engaging post which is raised upon movement of the lever from an upper to a lower position, and a latch for holding the lever in its lower position to hold the post in its raised position. A safety catch is movably mounted on the lever for movement relative to the lever between an operative position, in which it prevents release of the lever from its latched position, and an inoperative position in which the lever can be moved from the lower to the upper position after release of the latch.

Abstract: A load bar (10) comprises a hollow main body (11) having a first and a second open end (21, 22). A first arm (12) is received through the first open end (21) of the main body (11), and is laterally movable therein. A second arm (13) is received through the second open end (22) of the main body and is also laterally movable therein. The positions of the first arm (12) and the second arm (13) with respect to the main body (11) and with respect to each other are releasably securable and adjustable. Also, a bulkhead is provided comprising a load bar (10) as above, and further comprising a header wall (80).

Abstract: A stand particularly adapted for use with snowmobiles or other snow vehicles to easily and quickly lift one end of the vehicle to allow for cleaning, inspection, or alignment of the continuous tracks used to propel the vehicle. The stand includes a tripod with a lifting lever which lifts the lift rod, and with a locking means to lock the lever in a raised position with the vehicle end elevated.
