Description

[Detailed Description of the Invention] The present invention relates to an improvement of a tape measure in a container, in which a tape measure made of a fine conductor of steel is housed in the container.

This type of tape measure is often used in construction, but the scale of conventional tape measures cannot be read when used at night or in a dark room, which is extremely inconvenient.

Therefore, in the present invention, we focused on the fact that this type of tape measure is made of steel or other conductor, and decided to solve the above drawback by automatically lighting the tape when the tape measure is pulled out.

That is, the present invention provides a tape measure in a container in which a tape measure made of a conductor is housed in the container, and a contact point is provided at the outlet so that the tape comes into contact with the tape when the tape measure is pulled out, and a light bulb is provided near the outlet, and the light bulb is connected to the It is characterized by being connected to a power source via a contact.

To explain based on the illustrated embodiment, 1 is a rectangular container in which a steel tape measure 2 is stored.

Reference numeral 3 denotes a draw-out port, and 45 a contact point provided at the draw-out port 3, which has a bent leaf spring structure and is provided in series in the draw-out direction so as to contact the side surface of the tape measure 2 when the tape measure 2 is drawn out.

6 is a miniature light bulb installed directly above the outlet 3, and T is a dry battery that serves as a power source.

The light bulb 6 is connected to a power source 7 and contacts 4 and 5 in an electrical circuit.

8 is a lens, 9 is a stopper, and 10 is a changeover switch.

When the tape measure 2 is pulled out from the outlet 3, the sides of the tape measure 2 come into contact with the contacts 4 and 5, and the circuit is closed.
lights up.

Therefore, the scale can be easily read by simply pulling out the tape measure 2 as in the conventional case even when used at night or in a dark room.

When the stopper 9 is screwed downward, it stops the rewinding of the tape measure 2, making it easier to read the scale of the tape measure 2.

In addition, the changeover switch 10 is normally moved downward and brought into contact with the a contact, and is configured to form a closed circuit when the tape measure 2 is pulled out, but when moved upward, it comes into contact with the b contact, Since it lights up regardless of whether the tape measure 2 is drawn out, it can be used as a flashlight.

Furthermore, these parts used for illuminating the scale or dissolving the flashlight are stored in the corner of the container 1 where the tape measure 2 is not stored, so the container 1 is not made unnecessarily large and is compact and convenient to carry. It is.

As described above, according to the present invention, the scale of a tape measure can be easily read even when used at night, in a dark room, etc. by simply pulling out the tape measure with a simple operation similar to the conventional one.

Further, the container for storing the tape measure is of almost the same size as a conventional container, so it is compact and convenient to carry.

These effects can be further improved if the contact point is configured to touch the side surface of the tape measure.
