DEVICE FOR SIGNALIZING A TREADMILL BELT MISALIGNMENT
First Claim
1. A device for signalizing a treadmill belt misalignment, utilized in a treadmill of the type which comprises:
- an elongated chassis seated on the floor;
an upper structure mounted in the front portion of the chassis, for the user to hold and control the operation;
a front roller, and a rear roller which are horizontally journalled in said chassis; and
an endless belt mounted around the front roller and the rear roller and presenting an upper path and a lower path, comprising;
two optical sensor assemblies, each comprising an optical emitting means, disposed in one of the positions above or beneath the lower path of said belt, andan optical receiving means, disposed in the other of said positions, said optical sensor assemblies operating between a belt aligned condition, in which said belt interrupts the luminous flux of said optical emitting means for the respective optical receiving means in each optical sensor assembly, and a belt misaligned condition, in which said belt allows the optical flux between one of said optical emitting means and a respective optical receiving means, said optical receiving means being operatively coupled to a visual and/or sonorous signalizing means mounted to the chassis, to activate said signalizing means upon the misalignment of the belt.

Abstract
The treadmill is of the type which comprises: a chassis; an upper structure; a front roller and a rear roller that are horizontally journalled in said chassis, and an endless belt mounted around the front roller and rear roller and presenting an upper path and a lower path. The device comprises two optical sensor assemblies, each comprising an optical emitting means, disposed above or beneath the lower path of said endless belt, and an optical receiving means, disposed in the other of said positions, said optical sensor assemblies operating between a belt aligned condition, interrupting the luminous flux from said optical emitting means to said optical receiving means, and a belt misaligned condition, in which said belt allows the optical flux between one of said optical emitting means and a respective optical receiving means which is operatively associated with a visual and/or sonorous signalizing means to activate said signalizing means upon the misalignment of the belt.
