  • Patent number: 6688661
    Abstract: An inexpensive, lightweight, safe bumper beam (10) has an optimum strength characteristic and is capable of effectively coping with all kinds of collisions including slight collisions and strong collisions. The bumper beam (10) is disposed on a front or rear end part of a vehicle. Joining parts of the bumper beam (10) are attached to stays (2a, 2b) attached to, for example, front end parts of longitudinal frames (1a, 1b) of a body of a vehicle so that the bumper beam (10) extends laterally. The bumper beam (10) includes a bumper beam body (3) extended laterally and having a closed section and a reinforcing beam (4) extended in and along the bumper beam body (3). The reinforcing beam (4) includes a lateral upper wall (4a), a lateral lower wall (4b) and a front wall (4c) formed integrally with the upper and the lower walls (4a, 4b) to receive a longitudinal shock exerted on the vehicle.

  • Patent number: 4489944
    Abstract: An amusement device consisting of a manipulative egg-shaped puzzle having top and bottom housings rotatably connected by an internal mechanism. The top housing has a movable slide and a transparent window therein. The internal mechanism comprises a color marking thereon; a shaft fixedly connected to the bottom housing and extending from the bottom housing to the top housing; and a biased lever extending into the shaft for normally holding a movable weight at the top thereof, and an internal housing for supporting a plurality of rotation rings, each of which has a color marking thereon and a lever receptacle therein. When the bottom housing is rotated relative to the top housing the plurality of color markings may be aligned at the transparent window. Properly aligning the color markings necessarily aligns the rings and lever receptacles to allow the lever to move into the lever receptacles and out of the shaft.
