Description

Purpose of the invention:

This invention relates to "multi-nib instruments" and is intended for writing. Classification index "International Patent Classification" B43K 27/00.

Field of technology and its level

The closest to the claimed ballpoint pen and the method of use, its technical essence, are ballpoint pens with patents: US 2449939A from 1948, JPS 56115287U from 1981, 1785512 (USSR) from 1990, JPH 04102888U from 1992, JP 2005219472A from 2005 of the year.

All of these inventions have a common feature: all writing units are available simultaneously.

Along with this, all these inventions have a number of disadvantages. The writing nodes of the pen shafts are very close together and thus obstruct the writing view. Also, the angle of inclination of the pen in relation to the surface becomes very sharp, therefore the writing comfort is reduced, since the ball holder of the pen shaft can scratch the surface. If the angle between the rod and the surface is made more straight or tilted to the side, then there is a possibility of accidentally writing with two rods at the same time.

The invention under the number US 2449939A from 1948 uses the inclination of the tips of the rods from the opposite edge of the pen, this solution does not allow obtaining a large visible area for writing, since the writing nodes of the rods are large, close to each other and do not go beyond the boundaries of the pen, such the distance and their size are not suitable for comfortable writing, due to the obstruction of the writing surface by the neighboring writing unit, this forces the user to look under the pen, thereby writing with his head lowered on his shoulder. The handle uses a hexagon-shaped body, which, although it gives more convenience and comfort compared to the tubular shape (patents 1785512, JP 2005219472 A), but this shape does not allow the handle to be intercepted without errors due to the likelihood of grasping it in an intermediate state. that is, between two colors. At the same time, this handle model is suitable only for one type of rods.

In addition, for all these inventions, the writing nodes of the rod do not go beyond the boundaries of the body, this creates a problem for the color marking of ink on the body, so if you take the invention under the number 1785512 or JP S56115287 U and paint the tips with the appropriate colors, the user of this pen will have to look under it so that see what color to write in, and in which direction to turn the pen to select the desired color. If you make color marking on the edges, then before you start writing you will have to rotate the pen in your hands to find out where what color is. If you apply a color marking to the edge of the pen, then the color that will be directed to the user will not be the color in which he writes, which can be confusing, since the user does not see all the color markings at the same time, so about where the color is, he will have to remember.

DISCLOSURE OF THE INVENTION

A three-color ballpoint pen with a cap consists of: The bottom of the pen body (1) (fig. 1, 2, 6-9, 11), insert (2) (fig. 1, 2, 6, 11, 14, 15), the top of the body handles (3) (Fig. 1-4, 6, 11, 16-18), bushings (4) (Fig. 2, 11-13), cap (5) (Fig. 3, 4, 11, 19-21 ), rods (6) (fig. 2, 5, 10, 11) with a writing unit (7) (fig. 2, 5-8, 10, 11)

The present invention was made to solve the following problems:

1. Allow the user to change the color when writing, by rotating the pen around its axis (8) (Fig. 6-8).

2. To enable, if necessary, use the writing unit (7) (Fig. 6) perpendicular to the surface, such a need may arise when using an officer's ruler when outlining geometric figures.

3. Simultaneously see all the writing units (7) (Fig. 6, 7) and their color marking (9) (Fig. 6, 7, 9). This makes color selection easier and as a result increases the speed at which the pen color changes. This is achieved due to the deviation (10) (Fig. 8) of the writing units (7) (Fig. 6-8) from the central axis (8) (Fig. 6-8) of the handle outside the bottom of the body. This arrangement of the writing units (7) (Fig. 6) also gives a large visible area for writing. Along with this, this arrangement of the writing nodes (7) (Fig. 6, 7) allows you to draw an even circle, for this you need to put one of the writing nodes (7) (Fig. 6) on the surface, press your finger on top (3) ( Fig. 6) and turn the handle around its axis (8) (Fig. 6).

4. Ensure a confident grip and interception of the pen when changing the writing unit (7) (Fig. 6), this is achieved due to the shape of the bottom of the body (1) (Fig. 1, 6-9) of the pen, which is a triangular thin-walled prism with truncated ribs (11) (Fig. 8, 9).

5. Use the cap (5) (fig. 3, 4) for the handle as a stand. This use of the cap makes it possible to improve the flow of ink to the writing unit (7) (Figs. 2, 5).

This goal is realized due to:

1. The location of the writing units (7) (Fig. 2, 6-8, 10, 11) of the rods (6) (Fig. 2, 5, 10, 11) of the pen.

1.1. All writing units (7) (Fig. 2, 6, 7) are available at the same time. This provides a high speed of changing the color of the pen when writing.

1.2. The location of the writing units (7) (Fig. 7) are equidistant from each other (12) (Fig. 7) at the bottom of the pen body (1) (Fig. 6, 7).

1.3. The writing units (7) (Fig. 8) of the rod have a deflection angle (10) (Fig. 8) from the central axis (8) (Fig. 8) sufficient for comfortable writing. The recommended value is not less than 17 degrees, this provides soft writing, high quality lines. This position of the writing units (7) (Fig. 6-8) excludes accidental writing in two lines at the same time, even with a right angle between the writing unit (7) (Fig. 6-8) and the writing plane. At the same time, this arrangement of the writing units (7) (Fig. 6-8) provides a good view of the plane for writing due to their significant distance from each other. The result is the writing comfort of a single-point pen.

1.4. The shape of the guide cylinder (13) (Fig. 8-10), as well as the thickness (14) (Fig. 10) of the lower base of the cylinder (15) (Fig. 7, 8, 10) gives a greater visibility of the writing unit (7) (Fig. . 8, 10) of the rod (6) (Fig. 10). This provides a better view of the writing surface.

1.5. Inside the body of the handle, the rods (6) (Fig. 2, 11) fit snugly against each other in the center of the handle along the axis (8) (Fig. 11), due to the hole (16) (Fig. 12, 13) in the sleeve (4 ) (Figs. 11-13). This creates the required tension in the rods (6) (Fig. 2, 11), which does not allow the writing unit (7) (Fig. 2, 6, 11) to stagger when writing.

2. Shapes of the bottom of the handle body (1) (Fig. 1, 2, 6-9, 11).

2.1. The bottom of the handle body (1) (Fig. 1, 6, 8, 9) has the shape of a triangular thin-walled prism with truncated ribs (11) (Fig. 8, 9), this type of body provides a confident grip of the handle, as well as its error-free interception for selection of ink color by rotating the handle around its axis (8) (Fig. 6).

2.2. The truncated ribs (11) (Fig. 8, 9) allow you to more confidently rotate the handle around its axis (8) (Fig. 6), preventing the pen from slipping when changing the writing unit (7) (Fig. 6).

3. Color markings (9) (Fig. 6-11) of the pen shafts are visible at the same time (Fig. 6, 7, 9), you do not need to look under it or rotate to see and select the desired color, this speeds up the change of the writing unit (7) (fig. 6) at the handle.

4. Cap (5) (fig. 3, 4, 11, 19-21) for the handle:

4.1. To protect the writing elements, as well as from a possible break of the pen at the attachment point of the upper part (3) (Fig. 1) and the lower part (1) (Fig. 1) of the pen, a cap (5) (Fig. 3) is used, which is put on through the upper part (3) (fig. 1, 3, 4, 11) of the handle.

4.2. This type of cap acts as a stand for the pen and allows it to be stored in an upright position (Fig. 3).

4.3. When putting on the cap (5) (Fig. 11) on the handle, the tongues (17) (Fig. 11, 19-21) allow you to confidently hold onto the handle by the groove, which is formed due to the slightly smaller size of the insert (2) (Fig. 1 ).

• Connecting sleeve (4) (Fig. 2, 11-13), in the form of a triangular prism with truncated ribs (18) (Fig. 12, 13), and holes in the center (16) (Fig. 12, 13). The connecting sleeve is presented from two sides: bottom view (Fig. 12) and side view (Fig. 13).

• Inserts (2) (Fig. 1, 2, 6, 11, 14, 15), in the form of a triangular thin-walled prism, with truncated ribs (19) (Fig. 14, 15). The insert is presented from two sides: bottom view (Fig. 14) and side view (Fig. 15).

• The top of the handle body (3) (Fig. 1-4, 11, 16-18), in the form of a triangular thin-walled prism with truncated ribs (20) (Fig. 16, 17), rounded towards the top (21) (Fig. 17 , 18), having inside the protrusion (22) (Fig. 11, 16, 17), limiting the depth of entry of the sleeve (4) (Fig. 11, 13) inside the top of the housing (3) (Fig. 11). The bevel (23) (Fig. 17) serves to facilitate the passage of the shunts (17) (Fig. 11, 19-21) when putting on the cap (5) (Fig. 3, 4, 11). The top of the handle body (3) is represented by three sides: bottom view (Fig. 16), side view (Fig. 17), top view (Fig. 18).

• The handle cap (5) (fig. 3, 4, 11, 19-21). The handle cap (5) is presented from three sides: bottom view (Fig. 19), side view (Fig. 20), top view (Fig. 21). Cap (5) (Fig. 3, 4, 11, 19-21), having shunts (17) (Fig. 11, 19-21) for fixing the cap inside the groove, formed by the insert (2) (Fig. 1), which has a slightly smaller external size.

• Colored writing rods (6) (fig. 5). The pen shape described is suitable for both ball refills and helium refills. Structurally change: the proportions of the guide cylinder (13) (Fig. 8-10), the size of the hole in the base of the cylinder (15) (Fig. 10), the hole (16) (Fig. 12-13) in the sleeve (4) (Fig. 12-13), the height of the top of the handle body (3) (Fig. 1-4) for the length of the rod. For a better view of the writing surface, the recommended type of helium rod should have a narrowing (24) (Fig. 22), so the diameter of the guide cylinder (13) (Fig. 8-10) will not be excessive and interfere with writing.

The bottom of the body (1) (fig. 1, 2, 6-9, 11) of the handle consists of:

• Triangular thin-walled prism with truncated edges (11) (Fig. 8, 9), the base of the thin-walled prism has the form of a pyramid (25) (Fig. 6).

• Guide thin-walled cylinders (13) (Fig. 8-11), for the rods (6) (Fig. 10, 11), forming the required deviation (10) (Fig. 8) of the writing unit (7) (Fig. 8) from central axis (8) (Fig. 6-8), the recommended deviation is not less than 17 degrees.

• The location of the writing units (7) (Fig. 7) relative to each other should be equal to (12) (Fig. 7).

• Pyramidal protrusion (26) (Fig. 9, 11), to facilitate the direction of the writing units (7) (Fig. 11) to the guide cylinders (13) (Fig. 9, 11).

• The lower base of the cylinder (15) (Fig. 7, 8, 10), with a hole for the writing unit (7) (Fig. 7, 8, 10).

• Chamfers (27) (Fig. 10) between the thin-walled cylinder (13) (Fig. 10) and the lower base (15) (Fig. 10) have a functional significance. This chamfer does not allow the writing unit (7) (Fig. 10, 11) when bending the rod (6) (Fig. 11) to rest against the joint between the guide cylinder (13) (Fig. 10), and the lower base of the cylinder (15) ( Fig. 10).

• Color marking (9) (Fig. 6-11), at the bottom of the cylinder (13) (Fig. 8-11), to indicate the color of the ink at the writing unit (7) (Fig. 2, 6-8, 11) ...

• The limiter (28) (Fig. 8, 11), which is a protrusion that does not allow the sleeve (4) (Fig. 11, 13) to move further inward.

Bushing (4) (Fig. 2, 11-13), consists of:

• A triangular prism with truncated edges (18) (Fig. 12, 13) repeating the internal shape of the lower part (1) (Fig. 11) and the upper part (3) (Fig. 11), serving to connect the lower part (1) (Fig. . 11) and the upper part (3) (Fig. 11) of the handle.

• Hole (16) (Fig. 12, 13), which does not allow the rods (6) (Fig. 2, 11) to intertwine inside the handle body, as well as this hole creates tension in the rods (6) (Fig. 2, 11 ) as a result of which the tip of the pen shaft does not "walk" when writing.

Insert (2) (figs. 1, 2, 6, 11, 14, 15)

• Has the form of a triangular thin-walled prism (2) (Fig. 14) with truncated edges (19) (Fig. 14, 15).

• The outer size of the insert is slightly smaller than the outer body of the handle (Fig. 1), thereby creating a groove into which the key (17) (Fig. 11) of the cap (5) (Fig. 11) is inserted.

The upper part (3) (Fig. 1-4, 11, 16-18) of the handle body consists of:

• From a triangular thin-walled prism (Fig. 16) with truncated edges (20) (Fig. 16, 17), has a rounding upward (21) (Fig. 17, 18) for greater convenience when writing, and this shape is necessary for comfortable balance handle.

• Has sufficient length to accommodate the rods (6) (fig. 11).

• Has a bevel (23) (Fig. 17) to facilitate the passage of the key (17) (Fig. 11) of the cap (5) (Fig. 11).

• A limiting protrusion (22) (Fig. 11, 16, 17), which does not allow the sleeve (4) (Fig. 11, 13) to penetrate deeply into the upper part (3) (Fig. 11) of the handle.

Cap (5) (fig. 3, 4, 11, 19-21):

• Represents a thin-walled triangular prism (Fig. 19, 21) in the form of a truncated pyramid, having truncated edges (29) (Fig. 19-21).

• The key (17) (Fig. 11, 19-21) serves as latches for securely holding the cap on the handle body by the groove, which is formed due to the slightly smaller size of the insert (2) (Fig. 1).

Description of the technical result

To assemble the pen, it is necessary to insert the rods (6) (Fig. 2) into the lower part of the housing (1) (Fig. 2), the pyramidal protrusion (26) (Figs. 9, 11) should help guide the writing unit (7) (Fig. 11) into the guide cylinders (13) (Fig. 9, 11), the writing units are installed according to the color marking (9) (Fig. 9), while the chamfer (27) (Fig. 10) will not allow the writing unit (7) ( Fig. 10) to rest against the joint between the wall of the guide cylinder (13) (Fig. 10) and the base of the cylinder (15) (Fig. 10), then it is necessary to pass the rods (6) (Fig. 11) through the hole (16) (Fig. 12) bushings (4) (Fig. 11-13), while the rods (6) (Fig. 2, 11) should not intertwine with each other. Next, put on the sleeve (4) (Fig. 2) insert (2) (Fig. 2), then put on the upper part (3) (Fig. 2). The handle is ready for use.

The writing process is performed in a standard way, holding the pen with three fingers to grip the lower part (1) (Fig. 1, 6) of the pen body on three sides. To change the color when writing, you need to turn the pen around its axis (8) (Fig. 6) by 60 degrees.

At the end of the letter. The cap is put on through the upper part (3) (Fig. 3, 4, 11), then it is pushed to the lower part (1) (Fig. 3, 4). The pen is placed on the table with the cap facing down.
