Abstract: A gooseneck trailer system with support structures. The trailer system can comprise a gooseneck removably connected to a trailer and a support structure connected to the gooseneck. The support structure can be configured to support the gooseneck when the gooseneck is disconnected from the trailer. In some embodiments, the support structure can comprise at least one support arm connected to a frame of the gooseneck which can be pivoted between a retracted position and at least one deployed position. The present disclosure can also include methods of using the gooseneck trailer system with a tractor such that the support structure abuts against the tractor, safely securing the gooseneck to the tractor.

Abstract: A novel trailer securing and releasing mechanism for a boat is disclosed to facilitate the process when unloading and releasing a boat into the water as well as loading the boat back on the trailer via securing the boat's eye bolt, or ring. The invention device encompasses a spring- or hydraulically-activated mechanism normally attached to the trailer tongue. The boat loading mechanism operates by movement of a horizontal rod being forced in the direction toward the trailer resulting from contact by the boat ring. This contact and movement of the rod forward results in positioning the boat ring within an open claw-like device and, simultaneously, causes the open claw to slam shut wherein each claw arm lies with the boat ring and thereby affixing the boat to the trailer. As the rod arm is moved back within its housing by the forward motion of the boat the energy of said movement is captured and retained, either by a compression of a spring or of a fluid (gas or liquid) within a hydraulic mechanism.

Abstract: A bicycle power supplying device is configured to easily obtain the power needed to drive a subject electric component and a bicycle electric device that includes the bicycle power supplying device. The bicycle power supplying device includes a holder and a power storage unit. The holder holds a dry cell so that the dry cell is attachable to and removable from the holder. The dry cell includes a body, a first electrode arranged on the body, and a second electrode arranged on the body. The power storage unit is configured to store power of the dry cell and supply the stored power to a subject electric component.

Abstract: An extendable handle for a luggage including two parallel side rails each including an inner telescopic member, a sleeve having a cylindrical portion at an upper part and a semi-cylindrical portion at a lower part, a plug having an upper cylindrical portion and a lower cylindrical portion having a larger outer diameter than the upper cylindrical portion. The upper cylindrical portion is fitted into a lower end of the inner telescopic member, the lower cylindrical portion having a slot which divides the lower cylindrical portion into two legs. The legs are provided at an outer side with a plurality of hemispherical protuberances adapted to the cavities of the sleeve, and an outer telescopic member has an upper end in which is inserted the sleeve. The outer telescopic member has a tongue adapted to engage with the recess of the sleeve.

Abstract: An interlock device for a pressure-medium actuator, having a locking slide received in a housing and with an adjusting slide arranged transversely relative to the said locking slide and coupled kinematically to the locking slide, and, in an interlock position of a locking element connected to the locking slide, at least one positive engagement member provided on the locking element is in engagement with a corresponding mating engagement member on the actuator.

Abstract: A coupling system and device are disclosed for coupling a wheel chair or other transport device to a wheeled IV stand. In one embodiment, the system comprise a wheel chair having a first footrest and a second footrest, a wheeled IV stand having a pole, and a coupling device for connecting the IV stand to the first and second foot rest of the wheel chair.

Abstract: A draw bar for a towing tractor includes a draw bar bracket mounted on a weight of the towing vehicle, a draw bar pin provided for axial movement in an insertion opening in the draw bar bracket, an actuating lever provided near a driver's seat of the towing tractor, and a link unit interconnecting the actuating lever and the draw bar pin for shifting the draw bar pin on actuation of the actuating lever. The link unit is provided in the weight through an opening formed in the vicinity of the draw bar bracket of the weight and an opening formed in the vicinity of the actuating lever.

Abstract: When towing large aircraft with a tractor damage may at high speeds inadvertently be done to the nose wheel gears of the aircraft if the pilots of the aircraft apply the brakes. This can be avoided by automatic control whereby the transmitted force is sensed and the power and braking of the tractor is controlled on the basis of said sensing. By tractors of that kind it is difficult to sense the transmitted power directly. Instead, according to the invention, the acceleration of the tractor and the supplied power of the tractor are sensed. On the basis thereof it is possible to calculate the transmitted force and to drive accordingly.

Abstract: A four-wheel steering motor vehicle adapted to prevent a steering ratio of the rear wheels to the front wheels from varying at the time of sudden braking when the pressure of a brake liquid is reduced by an antilock brake unit.

Abstract: Devices for supporting an LPG tank bracket between overhead guard rear pillars of an LPG fork lift. Each supporting device comprises a mounting member which is removably mounted around the rear pillar and a member for supporting one end of the tank bracket, the supporting member being welded on the mounting member. Therefore, the LPG tank bracket can be supported between the pillars, even if the rear pillars are not specially designed for an LPG fork lift.
