Description

Automatic writing apparatus for segmental writing elements with caps}

The present invention relates to an automatic writing device, and more particularly, to an automatic writing device for a writing element with a cap.

Conventional automatic pencils have very thin writing elements that often break during writing, and in particular conventional automatic pencils typically have a pen tip tube of metal that may tear the paper due to inadvertent writing. This defect can be avoided by using a writing element pencil with a cap. The capped writing element pencil includes a plurality of axially arranged writing elements stored in a casing tube. Each writing element includes a pre-sharpened writing element supported by the element cap. This element cap includes a hole in its back to receive the tip portion of the next writing element. When the front writing element becomes dull or broken, it must be separated from the front opening of the casing tube and inserted into the casing tube from the rear opening of the casing tube. Unfortunately, however, the replacement action was made manually rather than automatically. Therefore, there is a need for the development of a writing element writing apparatus with an automatic cap.

Moreover, the pen tip of a conventional capped writing element pencil is not withdrawn and therefore a tip cap is necessary to protect the tip of the pen. If the tip cap is missing, the pen tip can no longer be protected.

It is an object of the present invention to provide an automatic capped writing element pencil.

It is another object of the present invention to provide a capped writing element pencil having a retractable pen tip.

As shown in FIGS. 1 and 2, the writing element pencil 1 with an automatic cap includes an outer tube 2, an inner tube 4, a writing element 6, a spring 8, and a stator 10. . Each writing element 6 has an element cap 14 with a tip portion 12 at its front end and a hole 16 for receiving therein the tip portion 12 of the adjacent writing element. Tip portion 12 is a pre-pointed writing element held by element cap 14. The writing element may be a pre-pointed pencil lead, a pre-pointed crayon, or other segmented handwriting element. Element cap 14 is made of plastic or metal. All writing elements are arranged on the axis one by one. Except for the earliest one, the tip portion 12 of each writing element is received in the hole 16 of the preceding element. The earliest writing element 20 is held by the writing element outlet 18 of the outer tube 20. A portion of the writing element 6 is disposed in the outer tube 2 together with the inner tube 4. The spring 8 acts as an elastic element for holding the inner tube 4 in its original position when the inner tube is not pressed. The remaining writing elements are stored in the inner tube 4. The recess portion 22 is formed on the inner wall of the outer tube 2 to receive the spring 8. A rise 24 is formed on the outer surface of the inner tube 4 to press the spring 8. The stopper 10 is installed at the upper end of the outer tube 2 to prevent the inner tube 4 from escaping from the outer tube 2.

The operation of the automatic capped writing element device 1 is illustrated in FIGS. 3-5. Initially, as shown in FIG. 3, the spring 8 is not pressed and the inner tube 4 is in its original position 30. Then, as shown in FIG. 4, the inner tube 4 is pressed from the top 28 to propel the writing element 36. The bottom opening 26 of the inner tube 4 engages with the element cap of the writing element 36. The writing elements 34 and 20 are also propelled by the writing element 36. The writing element 20 supported by the writing element outlet is replaced by the writing element 34. The spring 8 is urged by the riser 24 during the propulsion process. When the inner tube 4 is released from the driving force as shown in FIG. 5, the spring force generated by the spring 8 pushes the inner tube toward its original position 30. However, due to gravity, the writing elements stored in the inner tube 4 do not return to their original position, and the writing element 38 escapes from the bottom opening 26 of the outer tube 2 into the bore 35. 6 illustrates the use of an auto-cap writing element pencil 1 on an article 32. Since the element cap 37 of the writing element 38 engages with the bottom opening 26 of the inner tube, the writing element 34 acting as a pen tip is not pressed back into the writing element-outlet 18.

7 and 8 illustrate an automatic capped writing element pencil 39 with a retractable pen tip 41. Like the writing element pencil 1 with the automatic cap, the writing element pencil 39 with the automatic cap also includes an outer tube 40, an inner tube 42, a writing element 46, a spring 44 and a stator 48. Include. However, the automatic capped writing element 39 further includes a locking mechanism 51 for securing the inner tube 42 in the lower position when pressed. This locking mechanism 51 comprises an opening 52 formed on the outer tube 40 and a flexible piece 54 formed on the inner tube 42. When the inner tube 42 is in its original position, the flexible piece 54 is disposed on the opening 52 and pressed by the inner wall of the outer tube 40. When the inner tube 42 is pressed, the flexible piece 54 rises from the opening 52 of the outer tube 40. The outer tube further includes a clip 50. This clip 50 has a tip portion 60 that is raised towards the opening 52.

The operation of the automatic capped writing element pencil 39 is illustrated in Figs. 9-12. 9 shows that the pen tip writing element 41 is withdrawn from the writing element outlet 43 and the flexible piece 54 is disposed over the opening 52. When the inner tube 42 is pressed, the pen tip writing element 41 is pushed to and supported by the writing element outlet 43. The flexible piece 54 is moved to the opening 52 and rises because it is no longer limited by the outer tube 40. Moreover, the spring 44 is pressed during the propulsion process. When the inner tube is released from the propulsion, the spring 44 pushes upwards of the inner tube 42 upwards. However, as shown in FIG. 10, since the flexible piece 54 rises at the opening 52, this is the upper edge 58 of the opening 52 to prevent the inner tube 54 from returning to its original position. Will be distorted). To withdraw the pen tip writing element 41 again, the user must place the pen tip writing element 41 on the article 62 and press the tip portion 60 of the clip 50. The flexible piece 54 is then pressed by the tip portion 60 and no longer distorted at the upper edge 58. Thus, the inner tube 42 is pressed by the spring 44 to return to its original position 61. At the same time, the pen tip writing element 41 is pressed by the article 62 to be withdrawn into the outer tube 40.

Fig. 13 shows the appearance of a writing element pencil with an automatic cap. In order to guide the flexible piece 71 of the inner tube 72, as shown in FIGS. 14 (a) and 14, the guiding slot 64 has a posterior end from the opening 65 of the casing tube 74. Up to 66) on the casting tube (74). The inlet of the guiding slot 64 formed on the rear end 66 is enlarged to facilitate assembly of the casing tube 74 and the inner tube 72. The flexible piece 71 can be inserted very easily from the enlarged inlet 67 into the slot 64 and avoids difficulties in aligning the flexible piece 71 with the guiding slot 64. Done. Moreover, a surface 70 corresponding to the front surface 68 of the inner tube 72 is formed on the inner wall of the outer tube 74 to serve as the final point of the propulsion process of the inner tube 72.

FIG. 15 shows that a curved portion 78 is formed on the casing tube 76 to help the user grip the casing tube 76 more properly.

FIG. 16 shows the engagement between the element opening 88 and the lower opening 84 of the inner tube 82 of the writing element 86. The lower opening 84 of the inner tube 82 has a serrated rim for proper magnification. For the same purpose, the rim of the element cap 88 is pointed and, moreover, the writing element 86 is slightly inclined towards the wall of the outer tube 80 due to gravity. Such a situation can make a better bond between the inner tube 82 and the writing element 86.

The spring for pushing the inner tube can be arranged below or over the opening of the outer tube. 17 illustrates an example of placing a spring over the opening. An opening 94 is formed on the casing tube 90 opposite the tip portion 97 of the clip 96. The flexible piece 90 is formed on the inner tube 92. The recess 102 is formed on the inner wall of the casing tube 90 to receive the spring 100. The recess 102 is disposed above the opening 94. The rise 104 of the inner tube 92 is formed above the spring 100 to press it.

18 illustrates a writing element stopper 112 formed near the writing element outlet 108 of the casing tube 106 to prevent the pen tip writing element 110 from being pushed back to the writing element outlet 108. As shown in FIG. 19, the writing element stopper 112 is a flexible piece that exists at the end of the pen tip writing element 110. Furthermore, as shown in FIG. 20, raised strips 109 are formed around the pen tip writing element 110 to reduce the area of contact between the pen tip writing element 110 and the writing element outlet 108. Such a structure can prevent the pen tip writing element 110 from being distorted at the writing element exit 108.

However, for an automatic writing element writing device having a retractable pen tip writing element, a structure for supporting the pen tip writing element in the casing tube is required while the pen tip writing element is withdrawn. As shown in FIG. 21, the pen tip writing element 120 is pressed by an article 122 to be withdrawn within the casing tube 114. When the casing tube 114 is removed from the surface of the article 122, the pen tip writing element 120 does not flow down because it is supported by the lifting structure 118. The lifting structure 118 is a flexible piece that is absolutely formed in the wall of the casing tube 114. This structure may be formed near the writing element outlet 119. The lifting structure 118 has inclined surfaces 124 and 126 opposite the inner tube 115 and the writing element outlet 119, respectively. Thus, the lifting structure 118 is pushed out when the pen tip writing element 120 is pushed toward the writing element outlet 1119 or pressed by the article 122.

Although the present invention has been described so far as the most practical and preferred embodiment, it is not necessary to limit the invention to the embodiments described.

The present invention relates to a capped writing element pencil having a retractable pen tip, wherein a plurality of capped writing elements are stored in a casing tube so that they do not break when writing or tear paper, The operation is automatic and simple, and the pen tip is retractable to protect the pen tip.
