Abstract:

A shoe that relates to safety of the participants' when sports shoes with cleats are employed, e. g. golf, football, and soccer. Knee, ankle, & hip injuries are brought about by abrupt leg turns after the foot is planted and the participant's knee continues to move in a separate direction. A principle objective of the present invention is also to enhance the participants' performance. The primary objective, however, is to minimize the frequency and/or seriousness of knee, ankle, and hip injuries brought about by knee and leg turns after the foot is planted on the playing surface. This invention will permit the foot to rotate under magnetic control when enough pressure is exerted by the participant's body.

Abstract:

A device for enabling the driver of a vehicle to view behind the vehicle as he is driving. The apparatus includes a number of elongated periscopes mounted generally vertical within the vehicle. The periscopes are mounted so as to provide adjacent angular fields about a generally vertically-oriented axis. The device further includes a plurality of sleeves, each sleeve receiving a corresponding periscope for axial movement for relative thereto. The sleeves are mounted for movement about a generally horizontal axis. Each sleeve includes a pawl member which projects axially from its corresponding sleeve. The apparatus is, further, constructed so that when a main body portion of a periscope is moved telescopically within its corresponding sleeve to bring that sleeve into engagement with a collar carried by a head portion of the periscope, the pawl member will enter one of a plurality of circumferentially-spaced notches formed in the collar to enable rotation of the main body portion of the periscope tube about the axis of elongation thereof.
