ABSTRACT:
FIELD OF THE INVENTION
The present invention relates generally to a measuring tool, and more particularly to a measuring tape.
BACKGROUND OF THE INVENTION
As shown in
FIG. 1
, a measuring tape of the prior art comprises a bottom housing
2
, a cover
3
, a reel
4
on which a tape blade
5
is wound, a press button
8
for actuating a tape-stopping member
6
.
As shown in
FIG. 2
, the tape blade
5
is wound on the reel
4
such that the tape blade
5
is automatically rewound as soon as the tape blade
5
is pulled out unless the press button
8
is pressed. The user of the prior art measuring tape may be too busy to keep pressing the press button
8
while using the measuring tape. A forgetful user of the prior art measuring tape is apt to forget pressing the press button
8
while using the measuring tape. Some users may be even annoyed by the inconvenience in using the prior art measuring tape.
SUMMARY OF THE INVENTION
It is the primary objective of the present invention to provide a measuring tape with a means for preventing the tape blade of the measuring tape from being rewound as soon as the tape blade is pulled out.
It is another objective of the present invention to provide a measuring tape which is simple in construction and is thus cost-effective.
In keeping with the principle of the present invention, the foregoing objectives of the present invention are attained by a measuring tape, which comprises a housing in which a pivot is disposed such that a reel is mounted on the pivot. A tape blade is wound on the reel such that the tape blade can be pulled out of the housing via an opening of the bottom of the housing, and that the tape blade is prevented from being rewound by a stop member which is movably disposed in an action slot of the bottom of the housing. As the stop member is pushed forward, the press portions of the front end of the stop member and the urging portion of an arresting portion pivoted in the housing work together to prevent the rewinding of the tape blade. When the stop member is pushed backward, the arresting piece is caused to swivel backward so as to move away from the pliable tape blade, thereby enabling the tape blade to be rewound.
The foregoing objectives, features, functions, and advantages of the present invention will be more readily understood upon a thoughtful deliberation of the following detailed description of the preferred embodiments of the present invention with reference to the accompanying drawings.
