  • Patent number: 6230925
    Abstract: Disclosed is a light weight handle assembly adapted to transport a heavy duty container which may contain sensitive electronic components. The handle assembly of the present invention generally comprises a stationary bracket which mounts to a container wall and a movable handle pivotally connected to the bracket. The bracket is formed with an inner portion that is adapted to rotatably engage with a pair of pivoting arms extending from the movable handle so that the light weight handle may easily be assembled and disassembled. Each of the pivoting arms is formed with a movable stop member which is advantageously positioned to contact and bear against stationary stop members which are attached to or are a part of the container to which the handle is attached.

  • Patent number: 5370254
    Abstract: Hinge and latching mechanism for containers having a cover and a base includes a latch which, at its upper portion, is shaped to hook over a strike integrally disposed on the cover. The lower portion of the latch rotates about a pin located between a pair of feet which are provided with hooks to engage a flange extending from a lip on the base. The hinge includes a body and two legs and the former is also shaped to securely engage a second strike also located on the cover. Each leg has a foot which is also hooked to engage the flange of the base. To further secure the hinge and latch, each hook is fastened together and to the container. This structure ensures that hinge and latching mechanism are especially adapted for heavy duty applications while still being light in weight and small in size.

  • Patent number: 4732826
    Abstract: The invention concerns a battery jar having a modified interior side and end wall structure that both increases the electrical rating of the battery and reduces the quantity of material required to produce the battery jar itself. The interior of the jar is divided into upper, middle and lower sections and the wall thickness in each is different. The side wall thickness in the middle section is reduced by about 36-40% of the side wall to 60-64% of the thickness in the upper section and the side wall thickness in the bottom section is reduced by about 16 to about 20% of the upper to 80-84% section sidewall thickness. A plurality of ribs are also used on the end walls to maintain the length dimension within the jar between opposing end walls.
