Abstract

PURPOSE: To obtain a marking pen capable of holding a detachable cap covering a porous felt impregnated with ink by providing a continuous groove to become a passage for receiving a pivot unit of the cap extended at a cylindrical body from one end to a second end. CONSTITUTION: An arm 34 extended from a cap 30 has first and second protrusions 42, 44 extended in opposite directions from the end 34 of the outer arm. The protrusions 42, 44 are constituted to engage a passage of a cylindrical body 20 to turn the cap from a closed position to an open position. The body has a continuous groove 52 extended in a longitudinal direction from a first end 22 to a second end 24 or its near position. A pair of passages 54, 56 are provided near both sides of the passage 52, and engaged with the protrusions 42, 44 of the end 43 of the arm 34. Lengths of the passages 54, 56 are variable, and are sufficient in lengths so that the arm is turned and slid between the open position and the closed position.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a writing instrument, particularly a marking pen.

[0002]

Marking pens have become commonly used because of their versatility and unique marking characteristics. Not only are they used by artists and students, they are also commonly used in many businesses whenever bold and in the limelight. Improvements in inks, writing tips and manufacturing have steadily progressed to produce low cost, high performance writing instruments. The main advantage of marking pens is the ability to use porous felt tips with a variety of differently colored inks.

[0003]

Nevertheless, conventional marking pens have some essential drawbacks.
One of these drawbacks is that the pen's ink tip, typically the ink-impregnated porous felt, must be covered when not in use. Since the porous ink impregnated tips of many marking pens tend to dry when exposed to the atmosphere, these pens have removable caps that cover the felt tips when not in use for writing. Often, pen users will tend to inadvertently remove the cap and put it aside. When replacing the cap, the user is irritated for a few seconds to find the cap. This especially occurs when the user is busy and focused on his or her work. Thus, the ink impregnated tips of conventional marking pens have problems that are not encountered with other types of writing instruments such as pencils, colored pencils and the like. No convenient means of retaining the conventional cap used to cover the felt tip portion of the marking pen was available.

[0004]

In accordance with the present invention, an elongated cylindrical body having a first end, a second end and a passage in which the first end extends to the second end, in the passage. A writing device installed and extending outwardly from a first end, and a cap device, the body covering a first end of the cylindrical body, an arm extending from the first side of the body, a body of the body. A protrusion disposed on the opposite side to facilitate removal of the cap device from the cylindrical body, and a cap retaining device disposed on the first side to retain the cap in an open position, the cap further comprising a cap arm. A writing instrument having a pivoting device for pivotably and slidably positioning along a cylindrical body, wherein the cylindrical body has a continuous groove extending from a first end of the body to a second end of the body. Groove It said writing instrument having a serial installed passage portion extending toward the direction of the second end portion configured to accept a pivot device to the first end portion is obtained.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT In the preferred embodiment of the present invention, the disclosed marking pen 10 has a generally cylindrical elongated body 20. The cylindrical body can be made of a suitable durable material, preferably a plastic material. Cylindrical body 20
Is the first end 22, the second end 24, and the first end 22.
To a second end 24. A writing element 2 which has a tendency to dry when exposed to the atmosphere, such as a preferably porous ink impregnated felt strip.
8 is generally installed in this passage 26 and projects outward from the first end 22 of the body 20. The tip of the writing element is labeled 2 in Figures 2, 5, 6 and 9 to facilitate writing.
As shown by 9, the whole is obliquely cut.

At the first end of the cylindrical body 20 is disposed a cap member 30 for covering the writing element 28 when not in use. The cap member has a body portion 32 whose shape is substantially complementary to the first end 22 of the cylindrical body 20 of the pen. The cap member has a closed end 31 and an open end 33 that slides over the first end 22 of the cylindrical body 20 when trying to cover the tip of the writing element 28. A long arm 34 extends outwardly around the open end 33 of the cap member 30 and pivots the cap member 30 to the long cylindrical body 20 of the pen. From the open end 33 of the arm 34, as shown in FIG.
Slides off the ends and pivots downwardly to extend a distance sufficient to engage the cap receiving area adjacent the second end 24 of the cylindrical body 20.

The cap member 30 further includes a device for removing the cap from the pen body 20 by a human finger. The cap removal device, as shown in FIG.
The protrusion 36 is preferably shaped to fit the finger. The protrusion 36 shown is merely illustrative of one of a variety of shapes that are sufficient to facilitate removal of the cap from the pen when holding the pen with a human hand. On the other side of the cap removal device, after being removed from the writing element,
At least one cap retention device is provided for retaining the cap in the open position. The cap retention device preferably comprises two protrusions 46 and 47, which, as shown in FIGS.
It engages with grooves 62 and 64 provided in the wall of the passage 52 at the 0 bottom end.

The arm 34 extending from the cap 30 has first and second projections 42 and 44 extending outwardly and in opposite directions from the end 34 of the arm. Protrusions 42 and 4
4 is configured to engage the passage of the cylindrical body 20,
Pivot the cap from the closed position to the open position as described in detail below. The cylindrical body is the first end 2 of the body
2 has a continuous groove 52 extending longitudinally from the second body 24 to a position at or near the second end 24 of the body. A pair of passages 54 and 56 are provided near both sides of the passage 52 and are configured to engage the protrusions 42 and 44 of the end 43 of the cap arm 34. The length of the passages 54 and 56 is variable and is long enough for the cap arm to pivot and slide between the open and closed positions.

In operation, the cap can be removed from the end of the pen by pushing the protruding portion with a human finger. The cap is moved upwards from its seated position at the end of the cylindrical body until the tip of the writing element appears. The cap is then swung downwards along the side of the cylindrical body until it reaches the cap receiving area where the cap is fixed in its open position. When attempting to return the cap to the closed position, the cap is pivoted upwards and slid along the groove until it covers the writing element again. Although the present invention has been described with particular reference to the preferred embodiments thereof, it is understood that those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Will.

[0010]

Since the cap of the writing instrument is pivotally supported by the writing instrument main body, the cap is not lost when the writing instrument is used, and the vaporization of ink by leaving the tip of the writing instrument exposed without the cap is prevented. Can be prevented.
