Other objects of the invention and its particular features and advantages will become more apparent from consideration of the following drawings and accompanying detailed description
In some exemplary embodiments of the present invention, the multifunctional instrument comprises a stylus with an integrated illumination device. In other exemplary embodiments, the multifunctional instrument includes a stylus with an integrated illumination device and a writing instrument.
As shown in
The housing (12) is a hollow tubular shaft which can be made of any suitable material, such as plastic or metal. The shaft can be made of two or more smaller sections joined together. The housing (12) has a proximal end (14) and a distal end (16). The housing (12) accommodates a writing member (18), actuators to deploy or retract the writing member, and electrical circuitry and power source for the illumination device (30). The distal end (16) of the housing (12) has an opening through which the writing member (18) extends out when the pen (10) is in use.
The writing member (18) can be any device configured for writing and which is positioned inside a writing instrument, such as an ink cartridge or a pencil lead. The writing member (18) has a corresponding writing tip (19) located at the distal end (16) of the housing (12). For example, the writing tip (19) can be a ball point tip, a fountain tip, a pencil tip, a felt tip, a marker tip, a stylus tip, or another type of writing tip, depending on the type of writing member. In the embodiment shown in
In some embodiments, the writing member (18) may be deployed or retracted by pressing a button, or any other suitable actuator provided on the housing (12). This engages another actuator provided inside the housing (12) and causes the writing tip (19) to extend out of, or back into, the opening at the distal end (16) of the housing. In the embodiment shown in
An illumination device (30) is positioned at the proximal end (14) of the housing (12). In the embodiment shown in
The illumination device (30) is powered by a power source, such as a battery, positioned in the housing (12) and connected to the illumination device (30).
A pen light can be used in a variety of settings. It is a convenient means to carry a light source around without carrying an extra device. The most basic use of a pen light is as a flashlight to illuminate objects in the dark. Such use extends to more specialized settings such as hospitals, where medical personnel uses pen lights for diagnostic purposes, for example, to illuminate the back of a patient's throat during an oral examination. Other specialized uses include use by law enforcement officers to examine pupils of intoxicated suspects, or the use of a broad range of spectrums from ultra-violet to infra-red in forensic settings.
The illumination device (30) doubles as a push-button actuator for itself. Thus, to activate the illumination device (30), the device is pressed down and released. The same action turns off the illumination device (30). It is understood that any other suitable actuator may be used to turn the illumination device (30) on and off.
As shown in
The stylus (20) has a convex shape with curved edges. However, the stylus (20) may be any other suitable shape in accordance with the present invention, such as a pointed tip shape. The stylus (20) is hollow and covers the illumination device (30) located at the proximal end (14) of the housing (12). Thus, in some embodiments, the stylus (20) is sufficiently large to accommodate at least a top portion or the entirety of the illumination device (30). In other embodiments, the illumination device (30) is positioned inside the housing (12) adjacent the stylus (20) such that the illumination device does not occupy any part of the stylus.
The stylus (20) further has an aperture (22) through which the illumination device (30) is visible. In the embodiment shown in
To turn on the illumination device (30), the stylus (20) is pressed down and released with sufficient force to press down and release the illumination device (30) through the stylus. Pressing down on the stylus (20) in the same manner turns off the illumination device (30). The illumination device's (30) push button actuator is configured such that the force required to depress the illumination device (30) to toggle it on or off is greater than the force required to press the stylus (20) against a touch screen and generate sufficient contact for interaction. This minimizes the risk of inadvertently toggling the illumination device while using the stylus.
As noted above, the illumination device (30) may be turned on and off via any other suitable actuation mechanism.
It is noted that in other embodiments, the stylus (20) may not be entirely hollow, but may instead be made with a suitable material having a channel therein, such that the illumination device (30) is positioned in the channel and the light emitted by the illumination device (30) is transmitted through the channel.
The stylus (20) is made with a conductive material, such as conductive rubber or any other conductive elastomeric material, and may have screen-protecting coating. Preferably, the material of the stylus tip (20) is deformable enough to generate a proper contact area when the stylus (20) is pressed against a screen of the electronic device. The material is also flexible enough to allow the user to depress the illumination device (30) through the stylus (20) to toggle the light on or off.
In some embodiments, as shown in
When the cap portion (40) covers the proximal end (14) of the housing, as shown in
It should be noted that the writing instrument (10) shown in
In some embodiment, the illumination device (30) is positioned inside the stylus (20) such that it emits light from the stylus through the aperture (22) when activated. In other embodiments, the illumination device (30) is positioned inside the housing (12) adjacent the stylus (20) and the light emitted by the illumination device is transmitted through the aperture in the stylus.
The illumination device (30) may be configured such that it surrounds the writing tip (19). The illumination device (30) may comprise a plurality of LEDs positioned around the writing tip (19), as illustrated in
The stylus (44) is hollow and has an aperture (50), as shown in
To turn on the illumination device (52), the stylus (44) is pressed down and released with sufficient force to press down and release the illumination device (52) through the stylus. In order to turn off the illumination device (52), the stylus (44) is pressed down on in the same manner. The actuator of the illumination device (52) is configured such that the force required to depress the illumination device (52) to turn it on or off is greater than the force required to press the stylus (44) against a touch screen and generate sufficient contact for interaction. This minimizes the risk of inadvertently actuating the illumination device while using the stylus.
As noted above, the illumination device (52) may be turned on and off via any other suitable actuation mechanism.
In the exemplary embodiment shown in
It should be understood that the foregoing is illustrative and not limiting, and that obvious modifications may be made by those skilled in the art without departing from the spirit of the invention. Accordingly, reference should be made primarily to the accompanying claims, rather than the foregoing specification, to determine the scope of the invention.
