Abstract:
The present invention relates to a handcart having variable mounting boards. The present invention provides a handcart having variable mounting boards, comprising: a support frame, an upper portion of which has a handle; mounting boards which are arranged at the lower portion of the support frame, and each of which has a rail dome for enabling the mounting boards to slide in the left and right directions and enabling cargo loading/unloading operations to be easily performed; buffering means having a buffering wheel rotatably arranged at a side of each mounting board, a movable shaft which penetrates through one side of the mounting board, and a spring which covers the movable shaft so as to absorb shocks generated during the transportation of cargo; a guide assembly having a guide rail slidably coupled to the rail dome, a plurality of rack gears coupled to the rail dome, and spur gears which engage with the rack gears and which have rotatable handles; and a guide case which protects the rack gears and the spur gears from foreign substances, and which has an elongate hole for facilitating the sliding motion of the rail dome.
Abstract:
A hand truck (10), for transporting a large pail (40), includes a frame (12) that has a shaft (16) with one end to which a user handle (18) is attached and another end attached to a middle portion of a U-shaped frame section (14). The U-shaped frame section (14) has two spaced-apart legs (20, 22) with a separate wheel (24, 26) mounted to each leg (20, 22). A boom (36) is attached to and projects away from the frame (12) and has a receiver (38) for engaging a handle (42) of the pail (40). When the receiver (38) is engaging the handle (42) of the pail (40), rotating the frame (12) about the wheels (24, 26) raises the pail (40) which thereby becomes suspended from the boom (36). The pail (40), when suspended, is able to swing freely on the boom (36) without striking the frame (12) or the wheels (24, 26).
Abstract:
In a preferred embodiment, an apparatus, comprising: a column (42) normally generally vertical when a device (30) of which the column (42) is a part is in an operating position; and a platform (62) operatively connected at one end to the column (42) and normally generally horizontal when the device (30) is in an operating position, the platform (62) being selectively raised or lowered to raise or lower a load placed on the platform (62).
Abstract:
A hand cart cargo netting attachment (10) containing a quantity of netting (16), the attachment (10) for use with a standard hand cart (12). The attachment (10) has a housing (14) holding the netting (16) and a mounting plate (26) attached to the hand cart (12). The mounting plate (26) secures to the hand cart (12) and the housing (14) is mated to the rear surface (26R) of the mounting plate (26). The netting (16) is pulled out from the housing interior, at one side of the housing (14), is wrapped around the hand cart (12) and any packages held thereon, and is then secured to the opposite side of the housing (14). Once the netting (16) is secured in place, the packages are themselves secured onto the cart (12).
Abstract:
A hand trolley (1) of the type having a chassis formed from side frames comprising parallel frame members (6, 7), wheels (4) and a base platform (5), provided with a load lifting carriage (9) having a lifting surface (12). The carriage (9) can be raised from a low position on the base platform (5) to an elevated position by operating a hand cranked winch (20) with a crank handle (21) rotatable about an axle (22) located proximate to a hand grip on the chassis rails and parallel to the axis of the wheels (4). The positioning and orientation of the crank handle (21) allows correct ergonomic use by an operator (24) who can grip the trolley chassis with one hand (25) while controlling and operating the crank handle (21) in an ergonomically sound position.
Abstract:
An interactive laboratory robotic system is described that includes devices for use in a laboratory including a robotic assistant that can perform tasks and that can be controlled and configured by humans. The robot may assist personnel in performing repetitive tasks within a laboratory, and capture and store transactional and analytical data, such as during a DNA sequencing process. The robot may include sensors and/or cameras to detect, recognize, and track objects in an environment, and a manipulable arm having a hand for grasping objects. Other components of the system may include a sample tray graspable by the robot; a tray carriage for holding sample trays within equipment; an interactive shelf for holding sample trays; a mobile cart for mating with and charging the robot; and an accessory unit to enable the robot to open doors of equipment. The system may help to reduce or eliminate mistakes by personnel.
Abstract:
A catch mechanism (1), having a spring cam box (6) that is mounted to a pair of parallel shafts (10a-b) a retaining member in the form of a catch (41) being mounted onto the upper shaft (10a). The spring cam box (6) comprises a housing formed by two mirror image half components (12,13). Each housing component (12,13) includes three horizontal and substantially cylindrical through-chambers (121a,b,c). The uppermost chamber (121a) of each half (12,13) is a large travel chamber and is adapted to receive, in axial alignment, a pair of cam members, including a first outer cam member (15) and a slider or second inner cam component (14), an axial spring (16) and a section of the shaft (10a).
Abstract:
Hand trucks and methods for displacing an object with a hand truck are disclosed. An example hand truck includes a lifting toe and a lift apparatus coupled to the lifting toe and configured to displace the lifting toe. A microprocessor is configured to output a plurality of control signals. An actuator is coupled to the lift apparatus and is configured to displace the lift apparatus responsive at least in part to the microprocessor outputting at least one of a plurality of control signals. An example method includes changing the load on a lifting toe from a first weight to a second weight and activating an actuator responsive at least in part on changing the load. A lift sled is moved in a first direction responsive to the activation of the actuator and the lifting toe is moved in the first direction by the lift sled.
Abstract:
An apparatus is provided for loading water bottles into a water cooler. The apparatus includes a water bottle loading system for automatically installing water bottles into the water cooler and a water bottle storage insert with an inclined ramp adapted to laterally urge a plurality of water bottles towards a loading cradle of the automatic water bottle loading system under control of gravity.
