Description

The utility model relates to the production of writing devices designed to work in the dark or in low light conditions, as well as for other purposes, for example, as a flashlight to illuminate objects in the absence or low light.

Known writing device with a lighting system that allows you to write in the dark without additional lighting, which contains a hollow body with a hole at one end for the output of the head of the writing unit, for example, a ball rod with paste, and an electric circuit consisting of a series-connected power source (electric battery ), a pressure contact and a lighting element located inside the upper part of the writing device and a decorative cap in the form of a figure (in particular, a human skull) from transparent material. When the pressure contact is forcefully applied, the electric circuit closes and the lighting element begins to emit light. The luminous flux is directed to a decorative cap, through which light penetrates into the external environment, illuminating the surrounding space [see PRC patent No.CN 201183404 Y in class B43K 29/10 published on 01/21/2009].

Unfortunately, this writing device is almost impossible to use for writing in dark or low light conditions without additional lighting, which is due to the spatial arrangement of the light source, in this case, a decorative cap. When using a writing device, the cap is on top and, on the one hand, its glow simply dazzles the user, and on the other hand, the light from it does not fall into the writing, drawing or drawing area since the hand with which the writing device is held creates a shadow precisely in work area: a dark spot appears in it and the user is not able to work, but cannot even see the results of this work.

A slightly better option for placing a lighting element is proposed in a writing device with a lighting system that allows you to write in the dark without additional lighting, which contains a hollow body with an opening at one end for the output of the head of the writing unit, for example, a ball-shaped rod with paste, and an electric circuit consisting of a series-connected power source (several electric batteries), a pressure contact and a lighting element placed on a curved pocket holder in which there is I have a longitudinal groove along which the lighting element can move. Due to the curvature of the pocket holder, the lighting element can be tilted down to the side of the writing unit. When the pressure contact is forcefully applied, the electric circuit closes and the lighting element begins to emit light [see US patent No. US 2007/0041178 A1 no to class B43K 29/10 published 02.22.2008].

This writing device is also ineffective for use in conditions of limited lighting, since the lighting element, even in the lowest position on the pocket holder, is still located at an angle to the longitudinal axis of the writing device and above the user's hand, therefore, due to the specificity of its spatial orientation, he cannot fully illuminate the work area. In addition, the placement on the pocket holder of the lighting element makes it visually quite large, which the user may not like, since traditionally the pocket holder is traditionally located on the outside of the pocket. If this is the inner pocket of the jacket, the protruding lighting element, will cling to the shirt, irritate the body. If this is the breast pocket of a jacket, a prominent lighting element, it will look like a shiny brooch, which is not customary to wear among men.

The last drawback is eliminated in a writing device with a lighting system that allows you to write in the dark without additional lighting, which contains a hollow body with an opening at one end for the output of the head of the writing unit, for example, a ball rod with paste, and an electric circuit consisting of a power supply connected in series (micro-batteries), pressure contact and lighting element. The entire lighting system is made in the form of a miniature flashlight, mounted with the possibility of radial rotation relative to the axis of attachment near the rear end of the writing device. Thanks to the rotation of the miniature flashlight, the lighting element can be tilted down, illuminating the working area [see Chinese patent No.CN 201275948 Y for class B43K 29/10, B23K 3/00 published July 22, 2009].

However, this writing device does not solve the task of lighting the working area completely, since the lighting element, even in the lower position, is still at an angle to the longitudinal axis of the writing device and above the user's hand, therefore, it cannot completely illuminate the working area.

An attempt to illuminate the working area was made in the design of a writing device with a lighting system that allows you to write in the dark without additional lighting, which contains a hollow body of optically transparent material with an opening at one end for the exit of the head of the writing unit, for example, a ball-shaped core with paste, and an electric circuit consisting of a series-connected power source (two electric batteries), a pressure contact and a lighting element located inside the upper part of the writing casing devices under the decorative cap in the form of a figure (in particular, a prefabricated dolphin), also made of optically transparent material. When the pressure contact is forcefully applied, the electric circuit closes and the lighting element begins to emit light. Due to the fact that the body is made of optically transparent material, the writing device is fully lit, illuminating the surrounding space, including the working area [see German patent No. DE 202005009470 U1 according to class B43K 29/10 published on September 29, 2005].

Since the lighting element is located at a considerable distance from the working end of the writing device, then, despite the transparency of its body, there are large losses of light energy. Therefore, to obtain sufficient illumination, a significant increase in the energy source is required, which will inevitably lead to an increase in the overall dimensions and weight of the writing device, which create certain inconveniences for the user.

Otherwise, developers of a writing device with a lighting system approached the solution to the problem of working in the dark or inadequate lighting, providing it with a double external ellipsoid casing in cross section with two longitudinal channels, in one of which a regular writing device, for example, a pencil, is inserted directly, and in the second channel a small small diameter electric torch is installed, which illuminates the working area when using the writing device in darkened conditions [see US patent No.US 2008/0144308 A1 in class B43K 29/10 published 06/19/2008].

In addition to the fact that the flashlight does not fully illuminate the working area, it is extremely inconvenient to use such a device because of the rather large size of the case, which does not meet the ergonomic requirements of the size of a person’s hand, and an increase in weight makes the user quickly fatigued.

Chinese inventors slightly improved the above-described writing device of American colleagues, abandoning the bulky external case. Their proposed writing device with a lighting system that allows you to write in the dark without additional lighting, contains a hollow body with an opening at one end for the output of the head of the writing unit, for example, a ball rod with paste. A cylindrical electric flashlight with two finger batteries is attached directly to the case. The flashlight body is almost the same length as the writing device (due to the use of finger batteries, which are quite long). An electric light bulb protrudes from the lower end of the flashlight casing without a shade or any other limiter of the light flux, and a push contact is placed on the opposite end of the casing. When the pressure contact is forcefully applied, the electric circuit closes and the bulb starts to emit light in all directions [see PRC patent No.CN 201300617 Y in class B43K 29/10 published 02.09.2009].

This writing device slightly improved ergonomic indicators, but did not solve them completely: while holding the device, the user still has to interact with the fingers of two cylindrical nodes — the writing device’s body and the flashlight’s body, since they are not separable. In this case, an additional problem arises of blinding the user's light stream with the light stream, since the light bulb emits the light stream in all directions.

Somewhat later, other Chinese inventors improved the writing device of their predecessors by placing the bulb directly in the flashlight body, making the latter removable, and leaving all other nodes fundamentally unchanged [see PRC patent No.CN 201309334 Y in class B43K 29/10 published September 16, 2009].

However, this writing device still remained uncomfortable for the user, since it did not touch upon ergonomic issues, in particular, reducing the overall dimensions.

This problem was undertaken by American inventors by creating a writing device with a lighting system, containing a hollow body with an opening at one end for the output of the head of the writing unit, for example, a ball rod with paste. A cylindrical miniature electric flashlight is attached directly to the casing, attached to the casing with the help of a double clamp with semi-cylindrical folding parts fastened together using miniature screws. The electric flashlight has a relatively short length and diameter not exceeding the diameter of the writing device. With the help of a clamp, it can be moved along the body of the writing device and fixed with a screw in the selected location. The entire electrical circuit, consisting of a power supply (electric battery) connected in series, a push contact and a lighting element is located in a miniature flashlight [see US patent No.US 2008/0205038 A1 in class B43K 29/10, F21L 4/00 published 08/28/2008].

In this writing device, ergonomic issues have been resolved to some extent. It is enough to move the flashlight to the center of the case, and it will not prevent the user from manipulating the writing device. But at the same time a part of the light flux is lost. To strengthen it, the flashlight must be lowered down the case, but the writing device again becomes uncomfortable. In addition, no matter where the flashlight is located along the length of the casing, it creates a light spot above the working area, since it is parallel to the casing of the writing device, and the design of the clamps does not allow you to change the angle of the electric flashlight.

A more compact version of the electric flashlight mounted on the body of the writing device was proposed by German developers. The electrical circuit of their proposed technical solution is almost completely located in the writing device and only a lighting element equipped with a reflector is mounted on the lower part of the housing. This made it possible to minimize the size of the outer part of the flashlight [see German patent No. DE 202005014316 U1 according to class B43K 29/10 published on 04/27/2006].

But the smallest size of the protruding part of the lighting system outside the body of the writing device was proposed by Chinese inventors. As in the previous case, they placed the entire electric circuit inside the body of the writing device and only half of the light bulb protrudes from it [see Chinese patent No.CN 201268175 Y for class B43K 29/10, B43K 29/087, B43K 3/00 published July 8, 2009].

However, the two drawbacks described above share the same drawback: the luminous flux generated by their lighting elements creates a light spot slightly above the working area.

To eliminate this drawback, it is necessary to change the location of the lighting element. This is exactly what the inventor from Taiwan did. He proposed a writing device with a lighting system that allows you to write in the dark without additional lighting, contains a hollow body in which an electrical circuit is placed, consisting of a series-connected power source (electric finger battery), a pressure contact and a lighting element located on the lower end of the writing case devices. The housing in the lower part is equipped with an expanded section with an internal curved channel and with an opening at the lower end for the exit of the head of the writing unit, for example, a ball-stick with paste. Thanks to the expanded lower part of the body and the bending of the ball rod, the lighting elements are under the writing unit, illuminating directly the working area [see International application No. WO 00/72724 A1 in class A46B 5/02, B43K 29/10 published on 07.12.2000].

This writing device really allows you to illuminate the working area, however, it has a rather complex case design, not technologically advanced to manufacture. In addition, to insert the rod into the body, it must be bent at least two times, which is time-consuming, especially if the rod is made of hard material.

From the foregoing it follows that the most effective from all points of view will be the placement of the electric circuit completely inside the body of the writing device. And such writing devices are known.

So, for example, it is known that a writing device with a lighting system that allows you to write in the dark without additional lighting, which contains a hollow body of optically transparent material with an opening at one end for the exit of the head of the writing unit, for example, a ball-shaped rod with paste, and an electric circuit, consisting of a series-connected power source (finger-type electric battery), a push contact and a lighting element located inside the upper part of the writing device. When the pressure contact is forcefully applied, the electric circuit closes and the lighting element begins to emit light. Luminous flux, thanks to an optically transparent material, illuminates the entire housing and through it enters the working area [see French patent No. FR 2790999 A1 in class B43K 29/10 published September 22, 2000].

The disadvantage of this writing device is that its lighting element, located almost at the upper end of the housing, is located as far as possible from the working area, which leads to a significant loss of light output, partly due to dispersion during passage through an optically transparent housing. In addition, in this writing device, the lighting element is directed in the opposite direction from the working area, which further contributes to the loss of light power. This writing device is more efficiently used as a flashlight than a means of writing in the dark or in darkened conditions.

This disadvantage is eliminated in a writing device with a lighting system that allows you to write in the dark without additional lighting, which contains a hollow body of optically transparent material with an opening at one end for the exit of the head of the writing unit, for example, a ball-shaped rod with paste, and an electric circuit consisting of a series-connected power source (an electric battery in the form of a tablet), a pressure contact and a lighting element located inside the middle part of the writing device and lennn down the writing device. The walls of the body are made quite thick and fill the entire internal space of the body except for the channel for the writing unit - the rod. When the pressure contact is forcefully applied, the electric circuit closes and the lighting element begins to emit light into the inside of the housing. Luminous flux, thanks to an optically transparent material, illuminates the entire housing and is transmitted through it to the working area [see European patent No. EP 1371505 A1 in class B43K 29/00, B43K 29/10 published December 17, 2003].

Of course, the direction of the light emitter to the lower part of the housing allows you to get a more powerful luminous flux, however, still insufficient for normal operation in the dark or in low light conditions due to the location of the light source at a considerable distance from the working area and excessive losses of light power from - due to repeated refraction during passage through the thick walls of the body, moreover, the material of the body cannot be perfectly transparent.

In another writing device with a lighting system that allows you to write in the dark without additional lighting, containing a hollow body of opaque material with a hole at one end for the output of the head of the writing unit, for example, a ball rod with paste, and an electric circuit consisting of a power supply connected in series (electric batteries in the form of tablets), a pressure contact and a lighting element located inside the middle part of the body of the writing device and pointing down the writing device. The body of this writing device is hollow, that is, it does not have any obstacles (except for a centrally mounted thin writing rod) for the passage of the light flux from the light source to the working area [see Chinese patent No.CN 201224259 Y for class B43K 29/10 published on 04/22/2009].

The disadvantages of this writing device include the tangible loss of light energy associated with the location of the color source in the central part of the body, that is, at a considerable distance from the working area, and the transmission of light through a narrow long channel. Therefore, to obtain sufficient illumination, an increase in the power of the power source is required, and this inevitably leads to an increase in the size and weight of the writing device.

The closest to the proposed in its essence and the achieved effect, taken as a prototype, is a writing device with backlighting of the lower part of the body containing a hollow body with a hole, a writing element mounted in the hole and located on the lower end of the body lighting element connected in series with the pressure contact and a power source, and the lighting element is placed at an angle to the axis of the writing element, is made in the form of a torus and has light sources fixed to the power supply panel, distributed decomposition in a torus whose inner surface is provided with a reflective coating [see. Russian patent No.RU 2017627 C1 according to class B43K 29/10 published on 08/15/1994].

This writing device has at least three significant drawbacks.

Firstly, it has a rather complicated design, including non-standard rarely encountered parts, in particular, a torus with a reflective surface, in which, in addition, light sources are placed. In addition to the fact that these parts are miniature, which complicates the technology of their manufacture, the production of such writing devices requires expensive non-standard equipment, which, in general, significantly increases the cost of the product and dramatically reduces maintainability (how to replace a failed torus, where to get it, while the probability of its mechanical destruction is rather high, since the writing device is designed to work in difficult, in particular, darkened, conditions).

Secondly, since the torus heats up from the light sources located in it, the writing element passing through it must be located with a guaranteed gap to prevent drying (thickening) of ink or paste, which generally makes the device useless for work in any conditions and at any time days.

Thirdly, the use of a torus as a lighting element, forces to significantly expand the lower end of the writing device, almost to the diameter of the case itself. For this reason, despite the bright illumination of the working area, the user cannot see the trajectory of the writing unit, therefore, cannot accurately manipulate the writing device to obtain an accurate and correct image on the storage medium, especially if you need to apply small signs or images, exactly copying them from the original or nature.

The utility model is based on the task of improving the usability of a writing pen with a backlight system by combining materials for manufacturing the body and placing the lighting system inside along the body by using a transparent for the lower part of the body and placing the lighting element as close as possible to the working area inside the pen body.

The solution to this problem is achieved by the fact that the pen for writing with illumination of the lower part of the body, containing a hollow body made in the form of one or more sleeves, inside which there is a writing rod, the end of which extends through the hole outside the lower part of the body, and a lighting element, sequentially connected to the switch and the power source, according to the proposal, the lower part of the housing is made of any material transparent or translucent for light, and also located in the lower part of the housing a lighting element, for example, an LED, in addition, an electrical circuit breaker is installed in the electric circuit, equipped, at the request of the user, with a light flux power regulator.

The execution of the lower part of the casing made of transparent or translucent material allows access to the passage of light through the lower part of the casing of the pen to the working area, moreover, the location of the lighting element inside the casing prevents its destruction during careless or accidental manipulation or collision of the pen with objects in the dark. The location of the lighting element inside the lower part of the housing brings it as close as possible to the working area, which allows maximum use of the power of the light flux and, thus, minimizing the cost of electric energy, which increases the life of the electric energy source. In addition, the location of the lighting element inside the handle body allows you to get rid of any external unwanted protrusions on the bottom of the body and, thus, provides the necessary ease of use of the proposed handle, and also allows you to narrow the bottom of the body and, thus, not interfere with the user see work area. The inclusion in the electric circuit of the power regulator of the light flux allows you to take into account the degree of darkness of the working space, adjust the light intensity at the request of the user, taking into account his vision.

Thus, the proposed design changes in the handle with illumination of the lower part of the housing allow achieving the set technical result formulated in the statement of the problem.

It is clear that the above proposal can be applied not only to automatic ballpoint pens, but also to ordinary ballpoint pens, ordinary or automatic pencils, felt-tip pens, and other devices for writing or drawing with lighting systems for the working area.

The further essence of the utility model is explained in conjunction with illustrative material, which shows a longitudinal section of the proposed pen for writing with highlighting the lower part of the body.

The proposed pen for writing with illumination of the lower part of the body contains a hollow body made in the form of an upper sleeve 1 of an opaque or transparent material, and a lower sleeve 2 of a transparent or translucent material. Inside the pen housing there is a writing Rod 3, the ball end 4 of which extends through the hole 5 of the corresponding diameter outside the lower part of the housing. In the lower part of the housing there is a lighting element 6, for example, an LED that is connected in series with a chopper 7 of any known design, electrically connected to a power source 8, which uses any known batteries or accumulator. As the interrupter 7 of the electric circuit can be used the power regulator of the light flux of any known design, including those combined in a single design with the interrupter 7.

The proposed pen works as follows.

When you press the breaker 7, the electric circuit is closed and the lighting element 6 begins to emit light directed to the material used for writing, illuminating the working area around the tip of the ball end 4 of the rod 3. Due to the fact that the light source is as close as possible to the working area, it becomes possible to reduce energy consumption of the power source 8 and at the same time save light power, which increases the life of the power source 8.

As a lighting element, it is convenient to use light diodes (with a p-n junction) that provide maximum light output at a given power source 8. Additional convenience for the user creates the ability to change the color gamut of light at the request of the user due to the appropriate choice of LED type.

A significant difference between the proposed technical solution and the previously known ones is that the light source is located completely inside the lower transparent part of the housing, as close as possible to the working area, and the power sources are located in the upper part of the handle housing, and also that the switch can be equipped with regulator of power of a light stream. These differences, in total, can withstand all ergonomic requirements, significantly reduce the loss of light energy power, which, in turn, can reduce the dimensions of the power source or significantly increase its service life, ensure maximum lighting of the working area, create the most comfortable conditions for using the handle. None of the well-known pens of a similar purpose, as the above thorough analysis of the known technical solutions clearly shows, can have the noted properties.

The proposed technical solution is tested in practice. The Fairy pen for writing with illumination of the lower part of the case does not contain any elements and units that could not be reproduced at the present stage of development of science and technology, in particular, the production of writing devices, therefore, it is acceptable for industrial use, it has technical and other advantages before known similar technical solutions because of the proposed design changes, which confirms the possibility of achieving a technical result by the claimed object, in known sources of information and found these pens for writing with the specified in the offer essential features, but because it is considered to be such that it can receive legal protection.

The main technical advantages of the proposed technical solution, in comparison with the prototype, include the following:

- maximum efficiency of using the power of the light flux due to the placement of the lighting element in the lower part of the housing, that is, as close as possible to the working area;

- saving electric energy for the same reason;

- reducing the overall dimensions of the power source or increasing the period of its use without replacement for the same reason;

- simplification of manufacturing technology through the use in the design of common materials for the housing, components and elements in the electrical circuit;

- high maintainability for the same reason;

- increased ergonomic properties due to the fact that the electrical circuit is completely located in the handle body;

- the ability to control the power of the light flux due to the presence of an appropriate regulator in the electrical circuit;

- increasing the security of the lighting element due to its placement completely in the handle body.

The social effect of the implementation of the proposed technical solution, in comparison with the use of the prototype, is obtained by increasing the comfort of using a pen with backlight.

The economic effect of the implementation of the proposed technical solution, in comparison with the use of the prototype, is obtained by reducing the cost of the product as a result of simplification of its manufacturing technology, the use of common components and materials in the design.

After describing the proposed pen for writing with highlighting the lower part of the case, it should be obvious to specialists in this field of knowledge that all of the above is only illustrative, and not restrictive, as presented by this example. Numerous possible modifications to the pen, in particular, the number of lighting elements and rods or other writing units, can vary in different proportions, and, of course, are within the scope of one of the usual and natural approaches in this field of knowledge and are considered to be within the scope of this technical solutions.

The quintessence of the proposed technical solution is that the handle housing is partially made of transparent material, and the lighting element is located in the lower part inside the housing, and it is these features that together allow the proposed technical solution to acquire the listed and other advantages. Changing and using only certain structural elements of the proposed pen for writing naturally limits the range of advantages listed above and cannot be considered new technical solutions in this field of knowledge, since others similar to the pen described no longer require any creative approach from the designers and engineers, and therefore can not be considered the results of their creative activities or new intellectual property subject to protection by protective documents in accordance and with current legislation.
