Abstract

Bubble level, of the type of those that incorporate an elongated body in which one or more bubbles are integrated for leveling indistinctly horizontally or vertically, characterized in that one or more led, numerical diodes are also integrated into said elongated body. And positionally coinciding with said bubbles and provided for feeding them during the use of the level in areas with low ambient lighting.

Description

Bubble level.

Object of the invention

The present invention relates to a level of bubble, preferably those that use two bubbles, one for horizontal and other leveling measurements for pockets vertical

The object of the invention is to achieve a level bubble that is able to provide clear information thanks to the illumination of your bubble or bubbles.

Background of the invention

As is known, a bubble level is constituted from a considerably elongated body, which at least it incorporates a perfectly flat longitudinal face, to a correct settlement on a surface where perform leveling or poise measurement, being integrated into said body a bubble, specifically over the middle area of the same, opposite its support base, and usually a second bubble, perpendicular to the previous one, located near one of the body ends

These bubble levels, obviously if they are well structured, they offer correct functionality, allowing Good leveling.

However, on many occasions it is difficult make the corresponding "reading", because it is working in areas with low ambient light, a problem that in Sometimes it is accentuated by visual defects of the operator that is handling the level, so it is difficult to check when the bubble is in the correct position.

To date, only solutions are known handmade, such as lighting the level bubble with a lighter, use a flashlight, etc., all of them being uncomfortable, impractical and functionally nullify one of the hands of the operator.

Description of the invention

The bubble level that the invention proposes solves the problem fully satisfactorily previously exposed, allowing a perfect visualization of level bubbles, even in practice darkness.

To do this and more specifically, the level that it is recommended to incorporate, in the vicinity of each of its bubbles, a led diode, that is a luminescent diode capable of illuminate the said bubble for the short period of time necessary to check leveling.

According to another of the characteristics of the invention, the LEDs are powered by a solar cell, through of a small rechargeable battery or battery, assisted by a general switch and by a micro-switch that in push button functions are kept permanently open and that is Operated by the operator during level manipulation.

It is also planned that micro-switch is located at the base of the level, of so that the support of said level on the surface to be checked, either a horizontal element or a vertical element, occurs automatically feeding and consequently switching on the leds

Description of the drawings

To complement the description that is being performing and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical realization of it, is accompanied as part member of that description, a set of drawings where with illustrative and non-limiting nature, what has been represented next:

Figure 1.- Shows, according to a representation schematic in perspective, a bubble level made of according to the object of the present invention.

Figure 2.- Shows the electrical circuit of said level.

Preferred Embodiment of the Invention

In view of the figures outlined and in particular of figure 1, can be seen as the level that the invention proposes, like any conventional level, it is constituted by an elongated body (1) in which it remains integrated at least one longitudinal bubble (2), generally also a transverse bubble (3), to allow effect measurements or checks on both horizontal planes and on vertical planes.

However the body (1) could integrate exclusively a longitudinally centered bubble (2), or more than the two bubbles drawn in figure 1, without affecting the essence of the invention.

Said invention focuses on the fact that Each of the bubbles (2 and 3) is assisted by a LED (4), strategically integrated in the body (1) of the level next to the corresponding bubble, so that during handling of the level and when necessary due to low ambient brightness, The aforementioned LEDs (4) illuminate the bubbles (2 and 3).

The LEDs (4) are powered independently, assisted by respective resistances (5), forming part of a circuit that it uses as a source of power a small battery or battery (6), which can be of the type replaceable or can be rechargeable by a solar cell (7), also integrated into the body itself (1) of the level, and assisted by a voltage regulator (12).

In any case, the circuit establishes a general switch (8), which opens the circuit when it is not using the level, and a micro-switch (9) that assisted by a spring (10) tends to remain permanently open, and that installed in the level support base, close the circuit when said base rests on any surface, of so that once the main switch (8) is closed, the LEDs will they keep off while the level is not supported on the surface to control or level, which means a substantial saving of electric power.

According to a preferred example of Practical embodiment of the invention, said battery or battery (6) will be 9 V., to avoid any risk in the operator that manages the level and resistances (5) that assist the LEDs (4) they will be preferably 680 O.

Claims (4)

1. Bubble level, of the type that incorporates an elongated body in which one or more bubbles are integrated for leveling either horizontally or vertically, characterized in that in the said elongated body there are also integrated one or more led diodes, numerical and positionally coinciding with said bubbles and intended for feeding them during use of the level in areas with low ambient lighting. 2. Bubble level, according to claim 1, characterized in that said LEDs are integrated in a circuit provided with a battery, rechargeable or not, and a general switch to open and close said circuit, the LEDs being assisted by respective resistors . 3. Bubble level, according to previous claims, characterized in that in said circuit a micro-switch is also established, specifically in the support base of the level body, a micro-switch that tends permanently to remain in the open position, that is to say interrupting the electrical circuit, and that closes automatically when supporting the level on any surface. 4. Bubble level, according to previous claims, characterized in that when the battery is rechargeable, said electrical circuit also integrates a solar cell, integrated in turn into the body of the level itself.
