Description

[Detailed Description of the Invention] The present invention relates to writing instruments such as sharp pencils, ballpoint pens, and water-based ballpoint pens.

Sharp pencils and other writing instruments equipped with sound-producing devices have been proposed by the present applicant, but the conventional ones have complicated structures and are troublesome to install, so they are not very satisfactory.

In order to improve these drawbacks and provide various other features, the present invention has a hollow space created by cutting out the barrel of a writing instrument, and a reversible leaf spring is installed in the space. The sound can be produced by inverting the pressing leaf spring.

This will be explained below along with examples.

In the figure, sharp pencil, ballpoint pen,
Barrel 2 for storing a cursive 1 such as a water-based ballpoint pen
is made of plastic material, but it can also be made of metal material, wood, etc., and is provided with a tip cap 3 on the tip of which the above-mentioned cursive writing appears, as is known in the art.
An operating body 4 for pressing the cursive writing etc. protrudes from the rear end. The side wall of the shaft cylinder is cut out to an appropriate length to form a cavity 6 having a depth such that the leaf spring 5 can be reversed. The leaf spring is configured to be reversible to a size approximately corresponding to the length and width of the cavity. In the figure, a part of the side surface of the leaf spring is projected laterally to form a raised part 7, and when the raised part is pressed so as to be depressed, the leaf spring is reversed and makes a "pekon" sound. However, it is also possible to form two leg pieces in an open state at one end of the leaf spring, and connect the free ends of the leg pieces so that the whole body can be reversed (not shown). A mounting hole 8 is provided at one end of the leaf spring 5, and a pin 10 provided at the edge 9 of the cavity 6 is fitted into the mounting hole, and a presser piece 11 is fixed from the side by gluing, welding, etc. However, one end of the leaf spring is attached to the edge 9 by other appropriate means.
It is fixed to. The other end of the leaf spring is in contact with the opposite edge 12 of the space, and in the figure it is engaged with a step 13 provided on the edge so that it will not come off even if the leaf spring is reversed. It's like this. Note that one end or both ends of the leaf spring may be fixed with a pin or the like in a loose state that allows the leaf spring to be reversed. The operating body 4 may be equipped with an eraser or the like as is known, but in the figure, an inner cylinder 15 having an appropriate storage space 14 is shown.
An outer cylinder 16 is fitted into the inner cylinder 15 so that toys, dolls, mascots, and other items can be stored in the storage space. Note that the inner cylinder and outer cylinder may be formed to be transparent as appropriate.

Since the present invention is constructed as described above, the leaf spring can be easily installed in the hollow space of the shaft cylinder, and when the side surface of the leaf spring is pushed or released, the protrusion is reversed and "flattened". , Poko'', and since a leaf spring was placed in the empty space, the pronunciation resonated greatly,
It can be pronounced with a light rhythm.
