Description

Building block type writing implements {A BUILDING BLOCKS TYPE WRITING INSTRUMENT}

The present invention relates to a building block type writing implement, in particular a plurality of at least one connecting unit having a front end pencil lead and at least one connecting unit inserted into and engaged with another to form writing implements for two purposes, such as writing and actual building blocks. It relates to a structure constituting the writing component.

In the past, a hollow tube body A and a plurality of writing units C installed in the front end thereof are accommodated and each pencil core B is fixed with the head inserted into the tail in the tube A. We developed a kind of 'unsharpened pencil' that inserts a circular pencil lead as shown in 10. When the pencil lead B is installed at the foremost end of the writing unit C and worn out during writing, the writing unit C located at the front end of the tubular body A can be detached and positioned at the front end of the tubular body A. In order to push the second writing unit (C) to be inserted back into the tube (A) at the rear end of the tube can be continued writing. In this way it can be changed cyclically until the last writing unit C is worn out last. This is very useful because you don't use a small knife or pencil sharpener, but for this kind of writing instrument you can't use the entire pencil if you lose one of the writing units by any means, and (2) when you've run out of all the writing units. (3) The recyclable element has the disadvantage that it is a writing unit until it is discarded after being replaced only by the body and a new writing unit, because it must be discarded as a whole. It is totally against.

Referring back to FIG. 11, the pencil that does not shave penetrates through the plurality of socket units E and all the socket units E in such a way that the head can be inserted into the tail to form the tube D continuously. Construct a long pencil lead (F). The first unit E located at the front end is separated when the pencil lead F extending from the front end of the tube wears out. There is a new protruding pencil lead (F) of the socket unit for proper writing and the separated socket unit (E) can be inserted into the receiving hole located at the rear end of the socket unit (E) at the rear so that the initial tube B Still maintain the same length). Therefore, this is very useful for the recycling purpose of the socket unit, but at the receiving hole for the pencil lead, it is very loose, resulting in the pencil lead being pushed back and no writing at all. If this is too tight, the pencil lead will break easily when inserting / combining socket units. In addition, the reason why it is not mass produced and sold in the market is that the socket used cannot be used for other purposes.

In order to solve the above problem in the disclosed writing implements, the present invention is a function of the technology of US Pat. No. 5,044,804 and the writing units themselves connected in series, which are no longer fixed by an inner tube, as well as all the writing units, respectively. We propose such a new writing instrument that can be used as a writing instrument and is also a long writing instrument connected to each other. Moreover, the worn writing unit, worn out with a pencil lead, can serve as an educational building block that is collected and made into a three-dimensional toy as desired. So this will be very popular in the market. However, this kind of writing implement has a small change in the combination and the writing unit can be included in the same / opposite direction parallel to each other or combined with the other.

With the right of the above fact, the present inventor proposed an improved building block type writing implement of the present invention by extending various harmony and additional functions to enhance the value of related production.

Therefore, the object of the present invention can be used as a writing unit and a plurality of writing units having a pencil core at the front end thereof, and also can be used for play such as building blocks, can be combined to form a building block type writing instruments in more variations It is to provide a building block-type writing implement constituting at least one connection unit that is inserted and coupled to each other to form a structure.
