Description

    The present invention relates to a writing instrument, and it is necessary not only to provide a technical field that makes it possible to realize effective use of a pencil that is used in a short or unnecessary manner, or that is preliminarily short. From the field that provides and sells equipment and tools necessary for processing, manufacturing, transport, storage, assembly, and manufacturing, transport, and exhibition of these parts, to those materials, machinery and parts Necessary materials such as wood, stone, various fibers, plastics, various metal materials, etc., electronic components incorporated in them, control-related equipment integrated with them, various measuring instruments, Fields generally referred to as industrial machinery, such as the field of power machines that move equipment and appliances, the electric power that is used as energy, the energy that is the energy source, and the field of oil. Occurs in the fields related to the display, sale, import / export of these facilities and instruments, the results of their use, and the operation of the facilities and instruments for producing them. In addition to the fields related to the collection and transportation of trash, and the recycling field that efficiently recycles the trash, there are no technical fields that are not related to new fields that cannot be envisaged at this time.

(Points of interest)
When you use a commercially available pencil with one end cut into a cone, the pointed tip gradually becomes thicker and the tip becomes rounded or exposed from the shaft. When the number of cores is reduced, it has the property that it must be scraped again to expose the core from the shaft and be used after the tip of the core is sharpened. For this reason, the shaft portion itself becomes gradually shorter and difficult to grip. Eventually, it was impossible to even hold it normally, and it still had the uneconomical aspect that it had to be discarded even though there were still enough unused cores left.

    As one that reduces such waste, for example, one end of a rod-shaped main body of a size and shape that can be used as a writing instrument, as represented by the one proposed in Patent Document 1 (1) below. It has an entrance large enough to allow a pencil to be inserted into it, forms a hole with a certain depth, and the hole gradually becomes smaller as it goes deeper, making it easier to grasp a shortened pencil. The rod-shaped body with the insertion hole with a narrow back is easy to tilt in the mounting hole. It has a fatal defect that it is easy to come off due to pressure or external vibration while being carried.

(Conventional technology)
Considering such a situation, for example, as shown in Patent Document 1 (2), both ends of a pencil are thinned to the same diameter by the same length, and both ends are formed symmetrically. As a joint arrangement, they can be connected and integrated by wrapping adhesive tape around the outer circumferences of narrow diameters concentrically, etc., or as in Patent Document 1 (3) A drill for drilling in the center of the pencil is provided on the coaxial center of the first insertion hole for the pencil that is opened at a proper position on the main body, and on the coaxial center of the second insertion hole for the pencil that is opened at another appropriate position on the main body of the instrument. A cutting body for cutting the outer periphery of the pencil is provided, and a concentric cylindrical convex portion or a concentric cylindrical concave portion can be formed on the end portion of the pencil by cutting, so that the convex portion and the concave portion formed at the end portions of two or more pencils. There are some things that can be connected by combining

However, as shown in the former Patent Document 1 (2), the pencil ends that have been reduced in diameter are brought into contact with each other and fixed by winding an adhesive tape or the like after individual completion depending on the work conditions of the user. There is a risk that the connection strength will be greatly reduced if not assembled properly, the rigidity of the connecting part will be insufficient, and stress will concentrate when gripping and it will be bent easily. Stationery that can be cut into a shape that can be connected to the end of a pencil as typified by Patent Document 1 (3) Before processing each end, it is necessary to carefully cut the combination of the convex part and the concave part and carefully cut it. In addition to the inconvenience that the end of the pencil corresponding to the total of the convex portions of the concave portion must be cut again, there is a problem in the strength of the concave portion above all, and it is said that it will be used additionally. Even if it can be realized conceptually, it has to be considered that there is a high possibility that it will hardly be practically used due to the above-mentioned problems in processing.

(Awareness of problems)
As described above, using technical means that have been proposed in the past has problems in securing stability at the stage of use, and for users, especially children, processing for realizing the connection structure. It is almost impossible to always secure a connection structure that you would expect even if you are proficient and proficient. Therefore, there is a problem that sufficient strength cannot be obtained, and there is a concern that the joint part may be repeatedly broken and detached frequently during use. Because there is no way to solve the problems of the previous ones, there is no way to effectively use the resources, look around the pencil that becomes shorter and unusable Which has led to be aware of every.

(Object of invention)
Therefore, the present invention has sufficient connection strength in the added portion, has a connection portion that can be surely machined by anyone without mistakes, and is not merely an idea from the viewpoint of economy so far, Judging from whether it is possible to develop a new pencil refilling technology that can make use of worn-out pencils that are intriguing for the users, they will start developing and researching them quickly, and will make long-term trials. As a result of repeating mistakes and many trial manufactures and experiments, this time, we have finally succeeded in realizing a pencil with a new structure and a new set of joints for that purpose. The configuration of the present invention will be described in detail together with an embodiment representative of the present invention shown in the drawings.

(Structure of the invention)
As clearly understood from the embodiments representing the present invention shown in the drawings, the pencil of the present invention basically comprises the following configuration.

    In other words, a male screw that has been threaded by cutting the peripheral axis of the core into a concentric short column shape from an end-cut pencil that has become short or unnecessary after use, or that has been preliminarily short. Like a pencil for an end of a joint that is provided only at one end and a pencil for an intermediate end that is provided at both ends, each part is formed with a male screw at the end to form a joint pencil. On the other hand, each of the female screw portions is provided with both ends of female screw portions longer than the length of the male screw portion formed on the joint pencil, and each female screw portion can be screwed with any of the joint pencil male screw portions, In addition, an extension part formed by providing the female screw portion only at one end and the other end formed in a gripping portion having an appropriate length is prepared, and one extension end pencil as a connection pencil is provided. N intermediate pencils, n adapters, and one extension part are the female thread of the adapter The external thread of the extension pencil is screwed and connected to the last intermediate pencil, and the female screw part of the extension part is screwed and connected to the remaining male screw part to the desired length. It becomes the pencil which consists of the structure made into one thing.

    Furthermore, when expressed in different terms, the peripheral axis of the core is cut into a concentric short column shape from an end-cut pencil that is used up and becomes short or unnecessary, or is preliminarily short, and is threaded. Like the pencil for the end of the joint with the male screw part provided only at one end and the pencil for the intermediate part of the joint provided with both ends, only the male screw part is formed at the end. While providing a pencil, female screw parts longer than the length of the male screw part formed on these extension pencils are provided at both ends, and any of the extension pencil male screw parts can be screwed to each female screw part. And a decorative part formed with the male screw part only on one end and the other end in the shape of a head, and a transition end pencil, a transitional pencil. N intermediate pencils, (1 + n) adapters, and one decorative part are female adapters At the end of the adapter, the male screw part of the joint pencil is screwed and connected, and the male screw part of the decorative part is screwed and connected to the remaining female screw part of the last adapter. It can be said that it is a pencil made up of one.

    Furthermore, a male threaded portion that has been threaded by cutting the peripheral axis of the core into a concentric short column shape from an end-cut pencil that has become short or unnecessary after being used or that has been preliminarily shortened. In addition, like a pencil for an end of a joint that is provided only at one end, and a pencil for an intermediate end that is provided at both ends, both form only a male screw part at the end and make it a joint pencil. An adapter that is provided with female screw portions at both ends longer than the length of the male screw portion formed on these extension pencils, and each of the female screw portions can be screwed with any of the extension pencil male screw portions, and one Provided with a female screw part only at the end and a decorative part formed with the other end in the form of a head, one anchor end pencil as an anchor pencil and n anchor intermediate pencils N adapters and 1 decorative part are attached to the female thread of the adapter, and the male pencil thread The last joint intermediate pencil is integrated into the desired length by screwing and connecting the female screw part of the decorative part to the remaining male screw part. It includes a pencil with the following structure.

The example shown in the plan view of the pencil in which the adhesive is applied to the female thread portion of the adapter No. 8 is concentric only on one end of the end-cutting pencil 2 that has been used and shortened, or is preliminarily shortened. The joint end pencil 3 is provided with a male screw part B, and the intermediate part pencil 31 is provided with the male screw parts B and B at both ends. Provide both ends, and screw the joint pencil 3 male screw part B In addition to the adapter 4 that is made possible, there are two anchor end pencils 30, 30, and intermediate intermediate pencils 31, 31,... (1 + n) adapters. 4, 4,... Are obtained by unifying the male screw portion B of the joint pencil 3 into the female screw portion N of the adapter 4 and connecting them to a desired length. 1 shows a typical embodiment of the pencil of the invention.

    As shown in FIG. 1, the pencil 1 of the present invention is obtained by cutting the end of a regular hexagonal cross-section pencil having a concentric shaft 21 around a core 20 into a conical cone and using it for writing. Each time the exposed core 20 is worn away, it is used as usual until it is shortened while repeating the same cutting, and the edge pencil 2 that has been used after the grip portion is shortened is cut into a conical shape. At one uncut end opposite to a certain end, the shaft 21 is cut to be a short columnar portion 22 that is thicker than the core 20 and thinner than the outer diameter of the shaft 21, and the periphery of the short columnar portion 22 A male screw part B is formed to form a joint end pencil 30 for the tip which is the joint pencil 3, and the tip of the used end pencil 2 cut into a conical shape. The male threaded portion B is engraved on the end, and the end of the ring-shaped end opposite to the male threaded portion B is left as it is. In addition to forming the end end pencil 30 for the end, two end intermediate pencils 31 and 31 (n pieces) having male screw portions B and B engraved on both ends of the used end cut pencil 2 respectively. ) And a synthetic resin short pipe whose outer diameter is substantially the same as that of the end-cut pencil 2 and slightly longer than twice the male threaded portion B. After preparing three (1 + n) adapters 4 formed by engraving female threaded portions N that can be screwed into the threaded portions B, each of the joint end pencils 3 is a joint end pencil 30, 30 2. The two intermediate pencils 31, 31 and the three adapters 4, 4, 4 are connected to the female screw part N of each adapter 4, 4, 4 with the male screw part B of each anchor pencil 3. These are integrated by screwing and connecting.

    As shown in FIG. 2, the joint pencil 3 is processed into either the joint end pencil 30 or the joint intermediate pencil 31 by appropriately cutting the male screw part B at the end of the end-cutting pencil 2. As described above, the extension end pencil 30 has the shaft 21 portion at one end of the end-cutting pencil 2 opposite to the end that has already been cut into a conical shape. A short columnar portion 22 that is thicker than the core 20 and thinner than the outer diameter of the coaxial 21 is cut, and a male screw is engraved around the short columnar portion 22 to form a constant-shaped male screw portion B in a concentric convex shape. The end of the pencil 1 can be used for the tip of the pencil 1 and the male thread B is formed at the end of the end-cut pencil 2 which has already been cut into a conical shape. The part can be left as it is, and it can be used for the tip or end of the pencil 1, and further, the former conical end If the male threaded portion B is also formed at the end of the ring-like end, the latter can be changed to a joint intermediate pencil 31 which will be described later. It can be changed to the one for the tip of the pencil 1 or can be changed to the joint intermediate pencil 31 by forming the male screw portion B at the end of the ring shape.

The joint intermediate pencil 31 is obtained by cutting the male screw portions B and B on both ends of the end-cutting pencil 2, and either one of the male screw portions B and B on both ends has the end of the hook. If it cuts into a cone shape, it can change to the pencil 30 for joint ends for pencil tips.
The joint end pencil 3 and the joint intermediate pencil 31 that are the joint pencils 3 are formed by processing the shortened end pencil 2 but are replaced with new pencils (not shown). In addition, it is possible to process the male screw part B by factory production.
