  • Patent number: 7316368
    Abstract: The present invention relates to portable hose carts for handling and storage of flexible hoses, such as garden or air hoses. The cart is primarily constructed of plastic components having a centrally rotatable spool for winding of the flexible hose, an enclosure for supporting the spool, wheels at one end of the base of the enclosure, and a handle assembly for tilting the frame onto the wheels to facilitate moving the device. The handle assembly is telescoping mounted and includes a handle mounted near the top of the handle assembly. The spool is rotatable by either a direct current powered motor or a folding manual crank. Power from the electrical motor is transferred to the spool via an infinitely adjustable torque transfer assembly. When the cover is in the open position, the direct current motor is operationally locked out, and when the cover is rotated into the closed position, the direct current motor is operable.

  • Patent number: 7083136
    Abstract: A mechanism of a webbing retractor which can instantaneously apply driving force of a motor to a spool. At a base plate of a prime mover which is driven to rotate, two pawls are disposed at opposing positions at an outer side of an adapter connected to a take-up shaft of a webbing. The adapter includes a plurality of external teeth being formed along a periphery thereof at uniform intervals, a total number of which is an odd number. Accordingly, in a state in which both of the pawls contact the adapter, even if one of the pawls abuts an addendum of a tooth formed at an outer peripheral surface of the adapter, the other pawl does not abut an addendum of a tooth. One of the pawls quickly meshes with the adapter and rotates the adapter.

  • Patent number: 6935590
    Abstract: A flexible member sensor for detecting motion and tension of a flexible member includes a rigid member pivotally connected to a base, in contact with the flexible member. A sensor detects pivotal motion of the rigid member in response to movement of the flexible member. The sensor may provide a corresponding signal to a motion control system that adjusts the tension of the flexible member accordingly. In one implementation, the flexible member sensor is integrated with a feedback control system for an electric seat belt retractor that includes a feedback control loop. The flexible member sensor measures tension in seat belt webbing retained by the retractor. A motor coupled to a servo amplifier rotates a spool of the electric retractor to extract or retract webbing in accordance with the output of the flexible member sensor. The seat belt tension may thus be continuously maintained at a desired level.

A rotation disc, the torque limiter or the like is wholly disposed, along a radial direction of the external gear, between the external gear and a peripheral wall of a baseplate. Further, members such as pawls, a rotation disc and the like are disposed, along a radial direction of the peripheral wall, between the peripheral wall and an adaptor, and these members are accommodated at an inner side of the external gear. Consequently, a thickness dimension (axial direction dimension) of a clutch is practically the same as an axial direction dimension of the external gear, and this is extremely thin.

    Abstract: A webbing retractor has two torque transmitting routes for taking-up, such that rapid and reliable taking-up, and gentle taking-up are possible. When an engaging claw of a pawl restricts rotation of a ratchet plate, due to planetary gears rotating around a sun gear, rotation is transmitted from a drive gear to a carrier plate. On the other hand, when restriction of rotation of the ratchet plate is released, a clutch spring tightens around a tube portion of the carrier plate while rotation of the drive gear pulls one peripheral direction end of the clutch spring in a direction of rotation thereof. Frictional resistance between the tube portion and the clutch spring is increased, and rotation is transmitted from the drive gear to the carrier plate.

  • Patent number: 6427935
    Abstract: A seat belt retractor includes a base frame, a spool journalled to the base frame, a webbing wound around the spool, and a motor for rotating the spool. A speed-reduction mechanism is interposed between the motor and the spool. The speed-reduction mechanism includes at least one transmission train with a predetermined gear ratio, a common transmission element connected to the transmission train, and a resistant torque device connected to the transmission train. The common transmission element transmits rotation of the motor to the spool when the torque of the rotation is smaller than the preset value. Winding of the webbing is made based on the wearing condition of the webbing and the running condition of the vehicle.

    Abstract: A seat belt retractor has a winding reel rotatably mounted in a frame, an electric motor and a switching mechanism, with which varying torques can be transmitted to the winding reel to adjust the comfort of a wearer of the seat belt or to tighten the seat belt. The switching mechanism is automatically directed into a switch position set for the comfort perceived by the wearer of the seat belt and into a switch position for belt tightening, in which if necessary an adjustable load limitation is also achieved.

  • Patent number: 6328244
    Abstract: The Easy Arm Cable Winder Adapter is a labor and time saving device which allows small diameter cables to be retrieved and wound with an electric drill. The electric drill provides the torque required to retrieve and wind the cable. The Easy Arm Cable Winder Adapter can be modified to work with any brand or type of hand operated down hole instrumentation as well as to retrieve and spool any hand operated cable, wire, tube, line, filament, fiber, thread, string, twine, cord, rope or hose. More specifically, the Easy Arm Cable Winder Adapter significantly reduces the cost, time and effort required to retrieve Slope Indicator Company's Water Level Indicator (meter) cable and wind it back on its spool. Use of the Easy Arm Cable Winder Adapter on a water level meter makes sounding wells significantly faster and requires much less physical labor. The Easy Arm Cable Winder Adapter extends the range of applications for the water level meter and, in some cases, may preclude the use of more expensive technologies.

  • Publication number: 20010045483
    Abstract: A motorized seat belt retractor having a load limiter to control the tensile load on a seat belt webbing, especially when the webbing is withdrawn due to an emergency condition. The load limiter controls the tension by controlling the condition of the motor that drives the retractor.
