Abstract

A tape measure is disclosed which includes speed control device which allows the user to control the speed at which the extended tape is retracted into the housing. The housing defines a chamber and has a peripheral wall with a slot-shaped opening. A coiled tape blade within the housing is attached at it'"'"'s interior end to a spring which allows automatic retraction of the tape into the housing. The speed control device is attached to the outside of the housing above the slot shaped opening. Another opening in the housing exposes the tape so that a roller controlled by pressure from the speed control device will make contact with the tape in the event the user exerts pressure on the device. Said device is unaffected by various environmental conditions such as saw dust, particulate contamination or moisture. A handle is attached to the rear end of the housing, opposite to the speed control device, to facilitate manipulation and use of the tape measure.

Claims

1. A speed control device for a tape measure, said tape measure having a housing defining a chamber and having a peripheral wall with an aperture or opening, a coiled tape connected to a spring at a first end of the tape and wound around a bobbin set in the housing, and a tab attached to a second end of said tape to allow a user to grasp the tape when drawing out the tape through the opening, and positioned on the outside of said housing, immediately above the aperture formed on the lower end of a wall of the housing, the speed control device comprising:

a hinged lever mechanism which allows the user to press a finger on said speed control device, which will then apply pressure on a rubber roller which will make contact with the tape through a second larger opening in said housing, slowing the speed of the tape in direct proportion to the amount of pressure placed on said speed control device.

2. The tape measure with speed control device according to claim 1, wherein a handle is attached to the rear end of the tape measure housing
