Description

    The present invention relates to a mechanical pencil, and more particularly to a mechanical pencil that has a scale on the outside and can be expanded and contracted.

    A conventional mechanical pencil is a so-called writing instrument for writing letters and the like.

    On the other hand, as rulers having a scale in mm units, there are a sashi, an L-shaped ruler, a tape measure and the like.

  When using the above-mentioned sashi, L-shaped ruler, tape measure, etc., for example, at the construction site or at the measurement site for articles, especially when measuring simply at the measurement site, depending on the location, the tape measure bracket may become an obstacle or always carry. There was a disadvantage that it was inconvenient to keep.

  In order to solve the above-mentioned problems, the present invention provides a rear-end knock-type mechanical pencil of a mechanism in which the core housed in the shaft (2) is fed out from the base (11) by a certain amount by operating the knock button (10). A scale (4) of a minimum unit of 1 mm is printed on the front side of the shaft surface from the rear end to the front end, and a rectangular button (5) having a leaf spring mechanism (6) near the rear end on the back side of the front side scale printing portion. ), And has the same length as the shaft (2), and further wraps around the shaft (2), and is formed from an outer frame (3) that is slidable and expandable. ) Also has a graduation (4A) of a minimum of 1 mm from the rear end to the front end on the front side of the outer frame surface, and the back side of the front graduation printing part wraps the shaft (2) and slides the expansion and contraction. A rectangular button (5) formed near the mooring of the shaft (2) is moored One rear end hole (7) and another front end hole (8) are formed at the front end, and each of these is provided by a push spring mechanism (6) of a rectangular button (5) provided on the shaft. It is characterized by having a structure that can moor and release the shaft (2) in the hole.

  Since the scaled retractable mechanical pencil of the present invention is configured as described above, it is always carried as a writing instrument, so it can be used as a writing instrument in a state that wraps around the shaft and fits in an outer frame that can slide and extend. On the other hand, in a measurement site such as a narrow place, the scale can be easily measured with a scale as a ruler.

  Furthermore, the shaft main body and the outer frame are slidable and stretchable by the rectangular button of the shaft main body and the hole provided on the outer frame enveloping the shaft to be stretched, and are in the state where the shaft is extended and anchored to the maximum. If it is, the maximum value of the scale can be measured.

  Of course, it is an excellent one that can be used as a writing instrument even when the outer frame is moored to the shaft, or even when the outer frame is detached from the shaft.

It is a perspective view which shows one Embodiment of the scale side of the axis | shaft of this invention. It is a perspective view which shows one Embodiment of the outer side of the rectangular button which has a pushing spring mechanism of the axis | shaft of this invention. It is a perspective view which shows one Embodiment of the scale side of the outer frame of this invention. It is a perspective view which shows one Embodiment of the hole side where the rectangular button formed in the axis | shaft of the outer frame of this invention moored. It is a perspective view which shows one Embodiment of the scale side of the state which the axis | shaft of this invention was wrapped in the outer frame, and was fully extended. It is one perspective view which shows the mode of the back side of the state of FIG. 5 of this invention.

  The size, shape, design, material, manufacturing method, etc. of the scaleable telescopic mechanical pencil in the present invention are not particularly limited, but the shaft itself has a rear end knocking mechanism in which the core stored inside the shaft is fed out by a certain amount. A mechanical pencil is used.

  The scale formed on the shaft and the outer frame is also preferably formed, for example, in units of at least 1 mm by laser printing, silk printing or the like.

  As a rectangular button having a push spring mechanism provided near the rear end on the back side of the shaft scale printing part, as a leaf spring mechanism in which the end of the rectangular short part in the sliding expansion / contraction direction of the shaft is integrally formed with the shaft part It is preferable to provide it.

In the scaleable telescopic mechanical pencil of the present invention, it is preferable that the shaft and the outer frame are basically formed so that the length of the main body having the scale is the same. Of course, a clip that can be inserted into the pocket may be provided later on the outer frame, and there is no limitation.
Hereinafter, description will be made based on the implementation side and the drawings.

Implementation side

  FIG. 1 is a perspective view showing the surface side of the shaft (2) of the scaleable telescopic mechanical pencil (1) of the present invention, with a knock button (10) at the rear end and a base with a core at the front end. It can be understood that the scale (4) of at least 1 mm unit is printed from the rear end to the front end with the knock type mechanical pencil provided with (11).

  FIG. 2 is a perspective view showing the rear side of the shaft (2) in the state of FIG. 1, and the end of the rectangular short portion in the sliding expansion / contraction direction of the shaft (2) is near the rear end of the shaft (2). It can be seen that the leaf spring mechanism (6) is formed integrally with the shaft portion.

  FIG. 3 is a perspective view showing the surface side of the outer frame (3) that has the same length as the scaled portion of the shaft (2), wraps around the shaft (2), and is capable of sliding expansion and contraction. As with the shaft (2), a scale (4A) of at least 1 mm is printed from the rear end to the front end.

  FIG. 4 is a perspective view showing the rear side of the outer frame (3) in the state shown in FIG. 3, with only one rear end hole (7) for anchoring the rectangular button (5) formed on the shaft (2). The front end hole (8) is also formed in one place at the front end.

  When the rectangular button (5) of the shaft (2) is anchored in the rear end hole (7) of the outer frame (3), it can be used as a normal mechanical pencil.

  FIG. 5 shows a state in which the rectangular button (5) is pushed by a human hand, is recessed by the leaf spring mechanism (6), is slid and extended to the front end hole (8), and is anchored by the rear frame (3). The figure shows a state in which the end can be measured at the maximum extension as a ruler on the scale of the shaft and outer frame by placing the end in a narrow place to measure.

  FIG. 6 is a perspective view showing the rear side of the state of FIG. 5 and shows a state in which the rectangular button (5) is slid and extended in the front end hole (8).

Industrial applicability

  The scaleable telescopic mechanical pencil of the present invention can usually be used as a writing instrument as long as it wraps around a shaft and is housed in a sliding extendable outer frame. In this state, if the clip is provided near the rear end of the outer frame, it can be carried in a breast pocket etc. like other mechanical pencils or ballpoint pens.

  On the other hand, in a measurement place such as a narrow place, the shaft and the outer frame are slidable and expandable, and in particular, a rectangular button having a push spring mechanism provided on the shaft is anchored in a front end hole provided on the outer frame; Then, it can be used as a ruler that can measure up to the maximum value of the scale.
