ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a measuring tape dispenser with an impact buffer housing and tentative tape halting means, wherein the housing is entirely or partially covered with an impact buffer layer formed of an elastic material so as to protect the housing from being deformed or even destroyed by impact, furthermore a slip resistant effect and tentative tape halting means are also provided for the measuring tape dispenser.
2. Description of the Prior Art
FIGS. 1A and 1B
show schematic drawings of the structure for a conventional measuring tape dispenser. As shown in the drawings, a conventional measuring tape dispenser is constituted of a housing
11
, a brake button
12
, a tape
13
, a coiled spring
14
, and a reel. The housing
11
is made of a single brittle material, for example, acrylonitrile-butadiene-styrene (ABS) which is vulnerable to impact resulting in deformation or destruction. Besides, the slippery surface of the housing formed of the above mentioned material is apt to cause a measuring tape dispenser to skip out of the grasp of the sweating palm of an user and fall down on the ground.
As for the tape halting means for a conventional measuring tape dispenser, when it is intended to halt the moving tape
13
at a desired position, the brake button
12
is pushed downward to the lower position of a slide slot formed on the housing
11
so that the lower terminal
121
of the brake button
12
forcibly presses the tape
13
against the housing
11
and tightly sandwiches and detains the tape
13
therebetween. However, there is no means for tentatively halting the tape
13
at a transient position desirable during measuring work.
Coming to the realization of such shortcoming as described above, the present inventor carried out studies and experiments for a long time. Based on these studies and researches, the present inventor came to propose the present invention.
SUMMARY OF THE INVENTION
Therefore, it is an object of the present invention to provide a measuring tape dispenser with an impact buffer and slip resistant housing.
It is another object of the present invention to provide a measuring tape dispenser with tentative tape halting means.
To achieve the above mentioned objects, the tape housing of the present invention, as a conventional product, made of a single material for example, ABS which is vulnerable to impact, is entirely or partially, for example, only at the turning corners, covered with an impact buffer and slip resistant layer formed of an elastic material so as to protect the housing from being deformed or even destroyed by impact.
Besides, on the tape housing of the present invention, there is provided tentative tape halting means with an integrally formed push button, by lightly pressing the push button with a thumb against the side wall of a reel installed inside the tape housing to tentatively stop rotation of the reel thereby detaining the tape at a transient position desired by the operator during reeling in or reeling out the tape.
A more complete understanding of these and other features and advantages of the present invention will become apparent from a careful consideration of the following detailed description of certain embodiments illustrated in the accompanying drawings.
