  • Publication number: 20110176896
    Abstract: Restraints for restraining a vehicle at a loading dock are described. An example restraint described herein includes a brace movable between a holding position and a release position. A first portion of the brace engages a supporting portion of the vehicle and a second portion of the brace engages a non-movable location at the loading dock to restrain the vehicle relative to the loading dock when the brace is in the holding position. For the holding position, the first portion of the brace moves in one direction underneath the vehicle to engage the supporting portion and the second portion moves in a second direction underneath the vehicle to engage the non-movable location.

  • Publication number: 20110075441
    Abstract: Example light fixtures include one or more light transmitting illuminated rods that emit a series or array of discrete spots of light. Some example light fixtures disclosed herein include optical features that provide an intriguing, attention-getting affect that can be useful particularly in alerting personnel of certain conditions at a doorway of a truck loading dock. In some examples, the light transmitting rods are mechanically coupled to a housing that contains an LED light source. The mechanical coupling allows the illuminated rods to be readily replaced without disrupting with the operation or wiring of the light source. Some example light fixtures illuminate the cargo bay of a vehicle at the loading dock.

  • Patent number: 7914042
    Abstract: A vehicle restraint restrains a vehicle at a loading dock by engaging a rail that is part of the vehicle's support frame, wherein the rail is normally used for adjusting the position of the vehicle's rear wheels. In a preferred embodiment, the restraint includes an adjustable-length arm attachable between the vehicle and the loading dock. The arm includes a retractable or removable pin that engages one of a series of holes in the rail or releasably engages some feature of the loading dock. In some examples, the restraint clamps onto the rail, particularly if the rail has no available open holes for a pin to be inserted. In some cases, the restraint also provides the vehicle with vertical support.

  • Publication number: 20100260586
    Abstract: A wheel restraint for restraining a vehicle at a loading dock includes a wheel chock suspended from a tether. The tether hangs from an overhead beam such that the wheel chock can be swung down and underneath the vehicle and placed directly in front of a wheel of the vehicle. A pin can be used to help hold the chock to an anchor that is fastened to a driveway of the loading dock. The orientation of the pin and the anchor holes in which the pin can be selectively inserted prevents the chock from tipping back and makes the restraint more tolerant of dirt, ice and other contaminants. In some examples, an offset between the beam and the wheel results in the tether urging the chock toward the anchor.

  • Patent number: 7789168
    Abstract: The disclosure describes a handle assembly for a power tool that includes attachment means for attaching the assembly to a housing of a power tool. The handle means is adapted to be held by a user of the power tool and the handle means is mounted to the attachment means and is capable of limited movement relative to the housing of the power tool. The vibration damping means acts between said housing and said handle means. The vibration damping means can also comprise elastomeric material. The attachment means can be mounted in use to the housing via a bolt on one of the attachment means and the housing passing through a respective aperture in the other of said attachment means and the housing. At least some of the elastomeric material is arranged in use between at least one said bolt and a corresponding said aperture. The handle means can be pivotable and/or slidable relative to said attachment means. The vibration damping means can comprise at least one spring (e.g., compression/spring or torsion spring).

  • Patent number: 7762348
    Abstract: A power tool has a handle capable of limited movement mounted to its housing. An axle is rotatably connected to the housing and is movable between a first and second positions and is spring biased towards the first position. Arms are connected to and rotate with the axle. Connectors are slidably mounted within guides and are connected at one end to the arms and at the other end to the handle. Vibrations in the body of the power tool cause movement of one end of the handle, which causes movement of a connector and in turn movement of an arm. Movement of the arm causes rotation of the axle which therefore causes movement of the other arm. This in turn causes the related connector to slide within its guide and move the other end of handle. Thus, movement of one end of the handle is coupled to the other end.

  • Publication number: 20100170754
    Abstract: An example wheel restraint includes a wheel chock that is manually movable between a retracted or release position clear of a wheel of a vehicle at a loading dock and an operative position to block the path of the wheel. In the release position, the chock can be manually moved freely along a track that is mounted to a driveway of the dock. When the chock is manually moved from its release position to its operative position, a locking feature automatically restricts the movement of the chock relative to the track. When the chock is manually moved back to its release position, the locking feature automatically disengages. Although the wheel chock is connected to a track, much of the force exerted by the wheel against the chock can be transmitted directly from the chock to the driveway.

  • Publication number: 20100012339
    Abstract: A power tool, particularly a hammer drill, comprising; a body (4); a drive mechanism located within the body; at least one handle (10) moveably mounted on the body (4) by at least one connection point (18, 32; 16, 34); a vibration dampening mechanism connected between the body (4) and the handle (10) which reduces the amount of vibration, generated by the operation of the drive mechanism, being transferred from the body (4) to the handle (10); wherein the vibration dampening mechanism comprises a dampener (56); characterised in that the vibration dampening mechanism further comprises a restraining mechanism (52; 54) which restricts the direction of the movement of the handle (10) at the connection point (18, 32; 16, 34) where it mounts to the body to substantially the direction of the dominant vibration experienced by that connection point (18, 32; 16, 34). The restraining mechanism can comprise a pivotal lever or slide.
