摘要： The present invention relates in general to a fifth wheel hitch and method of using a fifth wheel hitch that is mounted to a bed of a towing vehicle, and more specifically, to a fifth wheel hitch that is vertically secured to a kingpin of a fifth wheel trailer without requiring the use of adapters or extensions. One aspect of the fifth wheel hitch and method of use includes a hitch head assembly that is adjustable in height such that the fifth wheel hitch is compatible with different sizes of towing vehicles and fifth wheel trailers. The hitch head assembly also incorporates a funnel shaped design for receiving the kingpin of the fifth wheel trailer in a vertical fashion to prevent the kingpin from sliding horizontally out of the hitch head after being pulled forward by the towing vehicle. A four-way pivot joint accommodates instantaneous variations in pitch and/or roll attitudes between the towing vehicle and the fifth wheel trailer connected by the fifth wheel hitch. The hitch head assembly further includes a latching and locking mechanism that indicates whether or not a secure connection has been properly executed between the fifth wheel hitch and fifth wheel trailer to assure an operator that the towing vehicle is ready for travel.

摘要： The present invention is an improved aftermarket lawn tractor hitch. The improved aftermarket hitch includes an upper support plate or member for attaching the plate to the tractor, a hitch pin for connecting to the towable implement, a compression spring surrounding the pin for holding the hitch pin in a closed position, and a lower support member. The user can open the hitch pin by lifting the handle on one end of the pin thereby releasing the tongue of the towable implement, which is held between the lower support member and the conventional tow tab.

摘要： A universal mounting clamps system and method for mounting a variety of accessories upon structures having various square, rectangular, or rounded profiles and various ratios and sizes, such as vehicle trailer hitches or bumpers, beams, posts, tubes, and pipes. In an angled-profile-structure embodiment using an angled mounting-clamp unit, an accessory-mount bracket is placed over a corner of the structure and provides area for mounting accessories. A clamping bracket is placed over the diagonally opposite corner of the structure and is fastened to the accessory-mount bracket using a fastener positioner. In a rounded-profile-structure embodiment, a curved mounting-clamp unit is fastened to the structure through a fastener slot, a positioner leg is held in position against the structure, and an accessory-mount leg is held extended from the structure and provides an area for mounting accessories.

摘要： A connecting device 1 of a towing vehicle 2 includes a connecting pin 13, a locking arm 22, and an actuator 23. The connecting pin 13 is provided to be rotatable between a connection position where the connecting pin 13 is brought into fitting engagement with a connecting plate 3a of a wheeled platform 3 and a disconnection position where the connecting pin 13 is taken out of the fitting engagement with the connecting plate 3a. The locking arm 22 is driven by the actuator 23 between a locking position where locking arm 22 is locked with the connecting pin 13 such that the connecting pin 13 cannot rotate out of the connection position toward the disconnection position and an unlocking position where the connecting pin 13 is unlocked in the connection position.

摘要： A hitch pin assembly includes a hitch pin, housing and shoulder bushing. The housing removably connects to the bushing when the bushing is seated in the aperture of a receiver tube. When the housing is so connected a plunger of the housing extends through the bushing and projects into the receiver tube. When the shank is inserted into the receiver tube the plunger tip catches the aperture of the shank, holding the shank in a position in which the pin-receiving apertures on the receiver tube and shank are aligned. The hitch pin is then inserted from one side of the receiver tube and into the bushing. A plunger in the housing translates along a projection in a track of the plunger to reveal the projection to the hitch pin tip and place it into position for engagement with the inserted hitch pin. The engagement holds the shank and eliminates rattling.

摘要： An industrial truck (21) with a jaw coupling (1) that includes a coupling body (22) and a coupling pin (4), a system including such an industrial truck and a trailer (40), and a method for coupling the trailer to the industrial truck. The industrial truck includes a control unit (28), at least one locking sensor (17) and a locking actuator (8). The locking sensor is configured to recognize whether a coupling eye (26) of a drawbar (18) of a trailer is located in a locking position within the coupling body. The control unit is configured to receive and evaluate signals from the locking sensor and, when the locking sensor recognizes that the coupling eye is located in or near the locking position, the control unit is configured to control the locking actuator so that it actuates the coupling pin such that the coupling pin is shoved through the coupling eye.
