Description

[Detailed description of the invention] "Purpose of the invention" (Industrial application field) This invention relates to a pen case with a running device, which is a pen case with a running device that is configured to be movable by disposing a running device on the bottom. Regarding.

(Prior Art) Conventional pen cases have only the function of storing writing instruments such as pens and pencils, and are rather uninteresting.

In addition, examples of pen cases that add elements of play that children can enjoy include, for example,
In No. 10713, a thermometer was placed on the lid of the pencil case, and in Utility Model Application No. 158426/1986,
A pen case or the like is disclosed in which an electronic sound generator such as a music box that senses the brightness of light and operates electrically is installed.

(Problems to be solved by the invention) <Problems with the conventional technology> However, in the case of such conventional pen cases, there is a play added to the original function of the pen case to store writing instruments such as pencils. All of the functions are mediocre, and it has not been possible to make writing instruments familiar to users, especially children in the lower grades of elementary school who are beginning to use writing instruments, and to satisfy their interests.

<Technical Issues> Therefore, this idea was to create a pen case with a completely new structure that is completely different from conventional pen cases, which even children in the lower grades of elementary school can quickly become familiar with, and which can also be used as a toy. It was devised as a technical issue to provide.

``Structure of the invention'' (Means to solve the problem) Therefore, this invention has a
The pen case body is configured to be movable by providing a running wheel and a drive device for rotationally driving the running wheel.

(Function) The function of this invention will be explained with reference to the drawings. By the above means, a drive device disposed at the bottom of the pen case main body 1, for example, a known drive device 3 using the restoring force of a mainspring, etc. The accumulated rotational driving force is transmitted to the running wheels 4A, thereby causing the pen case body 1 to run.

(Example) Hereinafter, an example of this invention will be described based on the drawings.

Reference numeral 1 shown in the figure is a pen case main body molded from metal, and a lid body 2 is attached via a pin 14 so as to be openable and closable. A known drive device 3 using the restoring force of a mainspring as a drive source is disposed on one side of the bottom of the pen case body 1 so that rotational drive force is transmitted to the running wheels 4A via an axle 13.

The drive device 3 is attached to the bottom of the pen case main body 1 by a cover body 6 molded from metal. That is, the cover body 6
It is formed into a substantially bottomless box-shape that surrounds the housing, and mounting pieces 8 are provided by horizontally bending both sides of the housing, which are formed slightly longer. One of the mounting pieces 8 is notched into three pieces, and the center thereof forms an insertion piece 7, which is inserted between two elongated notches 10 formed at appropriate positions on the bottom plate of the pen case main body 1. The other is fixed to the bottom plate of the pen case body 1 by caulking.

Therefore, there is no need to directly fix the drive device 3 to the bottom of the pen case body 1, and it can be easily fixed using the pre-formed metal cover body 6, so it can be manufactured in large quantities at low cost. can be manufactured.

In addition, on the other side of the bottom of the pen case body 1, there are running wheels 4 for stable running that are not linked to the drive device 3.
B is installed. However, this running wheel 4
B is a wheel notch 11 on the bottom plate of the pen case body 1.
The rising piece 12 provided when forming the notch
A cutout 9 is provided in the cutout 9, and the axle 13 of the running wheel 4B is mounted on the cutout 9.

Further, reference numeral 5 denotes an inner lid disposed within the pen case body 1, which also serves as a cover for the drive device 3 and running wheels 4A, 4B disposed at the bottom of the pen case body 1.

The drive device 3 can be arbitrarily selected from a drive source using the restoring force of a mainspring, a drive source using a battery-powered motor, a flywheel, and the like.

Next, to explain its use, the mainspring of the drive device 3 disposed at the bottom of the pen case body 1 is reeled in by reversely rotating the running wheels 4A connected thereto, and a reeling force is accumulated. By discharging this stored power, the running wheels 4A are rotated in the forward direction, and the pen case body 1 is caused to travel.

``Effect of the invention'' However, this invention has the driving force of the driving device 3 because the running wheels 4A, 4B and the driving device 3 that rotationally drives the running wheels 4A are arranged on the bottom of the pen case main body 1. The pen case main body 1 can be moved by rotating the running wheels 4A.

Therefore, in addition to being able to store writing instruments such as pens and pencils, it can also be enjoyed as a running toy.
In particular, it is possible to satisfy the interest of children in the lower grades of elementary school, and it is possible to make a pen case, which has conventionally been difficult to be familiar with as a learning tool, more familiar.

As explained above, according to this invention, various useful effects can be expected in practice, such as being able to play by running a pen case.
