    Abstract: A parallel link mechanism includes a first arm, a second arm, a first auxiliary link, a second auxiliary link, and a drive motor. A cylindrical connection shaft having a first rotational axis is provided near the proximal portion of the first arm. The proximal portion of the first arm is rotatably connected to a fixed base through the connection shaft. The distal portion of the second arm is rotatably connected to a movable base. The proximal portion of the second arm is rotatably connected to the distal portion of the first arm through a connecting portion connected to a transmission mechanism. The first auxiliary link forms a first parallel link together with the first arm, the connecting portion, and the fixed base. The second auxiliary link forms a second parallel link together with the second arm, the connecting portion, and the movable base. The drive motor drives the transmission mechanism to pivot the first arm and the second arm. The drive motor includes a motor shaft having a second rotational axis.

    Abstract: A simple and compact loader having a sufficient strength with brackets fixed on a working vehicle. Lift arms are pivoted at one ends thereof to respective brackets so as to be vertically swung by respective lift arm cylinders. Attachments are vertically swingably supported on respective tip portions of the lift arms. Bucket links are connected to the respective attachments so as to transmit the telescopic action of bucket cylinders. Each of the bucket links is offset laterally from each of the lift arms. The middle portion of each of the lift arms is disposed above a straight line connecting both ends of the lift arm to each other, so as to ensure a space for arranging a steerable wheel under the lift arm.

  • Patent number: 7434438
    Abstract: A folding brake includes a frame having a pair of vertically disposed and spaced side members and a lower clamp member rigidly attached to each side member and disposed in a horizontal plane. An upper clamp member is pivotally positioned in relationship to the lower clamp member for selectively clamping a workpiece positioned thereon. A first drive member generates a clamping force and selectively moves the upper clamp member. A pivotally mounted bend rail is engageable with a portion of such workpiece protruding beyond a front edge of the lower clamp member. A second drive member generates a bending force and selectively pivots the bend rail in a first direction to apply the bending force to such workpiece and in a second direction to disengage the workpiece. A controller is provided for operating the first and second drive members.

  • Patent number: 7396202
    Abstract: A preferred embodiment of a lift and carrier assembly for a personal-transportation vehicle includes a deck frame, a platform, and a trolley assembly mounted on the deck frame. The trolley assembly includes a drive nut, a motor for rotating the drive nut, and a drive screw threadably coupled to the drive nut so that rotation of the drive nut causes the platform and the drive motor to translate linearly in relation to the deck frame. The lift and carrier assembly also includes an arm assembly mounted on the trolley system and comprising a first and a second arm member, and an actuator pivotally coupled to the first and second arm members for moving the first and second arm members so that first and second arm members move the platform between an upper and a lower position in relation to the deck frame.

  • Patent number: 7354237
    Abstract: A loader boom arm for a material handling vehicle used in the agricultural or construction industries includes a post attachable to the vehicle, a lower arm pivotally connected to the post, an upper arm pivotally connected to the lower arm, a pivoting mechanism coupled to the post and the lower arm, and a link arm pivotally connected to the post and to the upper arm. The boom arm is raised and lowered in an angular direction of rotation by pivoting the lower arm about the post using the pivoting mechanism. As the lower arm is pivoted, the link arm causes the upper arm to pivot relative to the lower arm such that the upper arm pivots further in the direction of angular rotation than the lower arm, thus changing the angle between the lower arm and upper arm. The subject loader boom arm allows an operator to move material in a bucket attached to the boom arm to locations of higher elevation and further reach than typically available with conventional boom arms.
