  • Patent number: 11104189
    Abstract: An indexing block positioned within the receiver hitch and connected to a tri-ball block having a plurality of towing accessories (e.g., different sized hitch balls, pintles, hooks, etc.) on its separate, exterior facings. A biasing member and lock cooperate with an internal, coaxial plunger, thereby allowing for selective rotation of the tri-block relative to the indexing block, without the need to completely remove the assembly from the hitch receiver itself. Ball bearings fitted within the indexing block facilitate movement of the plunger and tri-block relative to the indexing block when the assembly is being rotated to position a new towing accessory in its desired place.

  • Patent number: 11084522
    Abstract: A steering assembly including a motor assembly, a worm assembly, and a coupler assembly is provided. The worm assembly includes a worm member defining a central axis and having first and second ends. The coupler assembly may include an adapter having a first wall defining a through-hole sized to receive a portion of the first end therein. The coupler assembly may operatively connect the motor assembly and the worm assembly. The worm member and the adapter may be arranged with one another such that pressing a swedge tool against a face of the worm member in a direction substantially parallel with the central axis deforms the first end to overlap a portion of the worm member onto a portion of the adapter adjacent the through-hole to secure the worm member and adapter to one another and to axially retain the worm member in a position relative to the central axis.

  • Patent number: 11040585
    Abstract: A trailer coupling comprises a cross member unit, which is mountable on a tail region of a body, and a bearing unit held by the cross member unit. A ball neck with a coupling ball is held on the cross member unit by the bearing unit. The cross member unit is connected in its two outer, mutually opposed end regions to mounting elements for fixation to the tail region. The cross member unit has an upper supporting structure and a lower supporting structure. The supporting structures are each connected at their mutually opposed outer end regions to the mounting elements and in a central region carry the bearing unit. One of the supporting structures is primarily torsionally rigid and at least partially surrounds a structure interior, and that the other of the supporting structures is primarily tensile stiff in the direction of travel.

  • Patent number: 11033444
    Abstract: Wheelchair with two independent driving arms fixed to the frame by pivot bearings at a low position. The driving arms extend to a sufficient height for the user to hold their upper portions and to move them in forward-backward directions around the pivotal bearings. Ropes are connected to the lower sections of the driving arms. Two large wheels have wheel hubs equipped with freewheel, and each wheel hub have a rope drums attached with a spring bias, and a winding made of rope. Pulling a the rope in forward direction results in turning the wheel hub in forward direction, and when the rope drum (31, 31?) is turned in the other direction the freewheel releases the connection towards the large wheel. The wheel hub comprises a release mechanism that releases the freewheel when the large wheel is moved in backward direction and backward movement gets allowed.

  • Patent number: 11008038
    Abstract: A vehicle steering assist system, including an engine pump, a flow-rate restricting mechanism, a motor pump, a motor-pump controller, and a steering-force assist device, wherein the steering assist system is configured to restrict an engine-pump ejection flow rate to be lower than a required receiving flow rate to be received by the assist device when the engine pump is operated by being driven by an engine rotating at an idling speed, the engine-pump ejection flow rate being a flow rate of a working fluid ejected from the engine pump to the assist device via the restricting mechanism, and wherein the motor-pump controller is configured to control a motor-pump ejection flow rate such that an insufficient flow rate of the working fluid is covered by the motor-pump ejection flow rate, the insufficient flow rate being a shortage in the required receiving flow rate not covered by the engine-pump ejection flow rate.
