Description

The The invention relates to a lighting for a hand tool, the one having a reflective lid and a transparent screen, wherein the transparent screen has more than two curved surfaces which are different Have curvature, making surfaces with different light intensity arise, and wherein the reflective cover and the transparent Screen quickly connected by a locking ring can, so that the light-emitting diode can be easily replaced.

Out TW M274206 and 389145 each a luminous hand tool is known. In the former, the lid that is locked with the handle must be removed when the LED is to be replaced. This is very power consuming. In the latter, the lighting is from behind pushed into the receiving space of the handle. Therefore, the whole must Lighting can be pulled out of the handle when the light emitting diode should be replaced.

In addition, points the translucent screen for the Light-emitting diodes no curvature on and thus has no effect on the light intensity.

Therefore are the conventional ones luminous hand tools when replacing the light emitting diode and the lighting effect very disadvantageous.

Of the Invention is based on the object, a lighting for a hand tool to create the above-mentioned disadvantages of conventional Overcome solutions can.

This object is achieved by the lighting according to the invention for a hand tool, comprising
a handle having a plurality of receiving recesses for light-emitting diodes and latching parts at the front end,
a lid which is fixed to the front end of the handle, having U-shaped recesses for the light emitting diodes and is provided on the outside with an annular groove, and
a transparent screen enclosing the lid, more than two translucent curved surfaces having a different curvature for the light emitting diodes, and provided with locking grooves for the locking parts of the handle, wherein a locking ring which engages in the annular groove of the lid, the transparent screen attached to the lid.

Of the Handle is with a power supply unit and a switching unit Is provided. The switching unit contains a switch and a push button, by the light-emitting diodes on and can be turned off. The power supply unit contains a plus line, a minus line, a positive pole, a negative pole, Batteries, a spring, a locking ring, a copper contact and a stopper.

By the curved ones surfaces with different curvature can with the device according to the invention different light levels be generated. In addition, you can the LEDs are easily replaced by the lock ring.

in the Below, the invention will be described with reference to an embodiment with reference to the drawing described in detail. In the drawing shows:

1 an exploded view of the device according to the invention,

2 a representation of the connection of the transparent screen with the lid and the handle,

3 a perspective view of the device according to the invention,

4 a sectional view of the device according to the invention.

How out 1 it can be seen, the invention
a handle ( 1 ), which at the front end a plurality of receiving recesses ( 11 ) for light-emitting diodes ( 12 ) and locking parts ( 15 ) having,
a lid ( 2 ) located at the front end of the handle ( 1 ) and reflective is formed to the light of the light-emitting diodes ( 12 ), the lid ( 2 ) U-shaped recesses ( 21 ) for the light-emitting diodes ( 12 ) and on the outside an annular groove ( 22 ), and
a transparent shade ( 3 ), which holds the lid ( 2 ) encloses more than two translucent curved surfaces ( 31 ) with different curvature for the light-emitting diodes ( 12 ), and with locking grooves ( 32 ) for the locking parts ( 15 ) of the handle ( 1 ), wherein a locking ring ( 4 ), which is in the annular groove ( 22 ) of the lid ( 2 ), the transparent screen ( 3 ) on the lid ( 2 ) attached.

The handle ( 1 ) is connected to a power supply unit ( 13 ) and a switching unit ( 14 ) fitted. The switching unit ( 14 ) contains a switch ( 141 ) and a push button ( 142 ) through which the light-emitting diodes ( 12 ) can be switched on and off. The power supply unit ( 13 ) contains a positive line ( 131 ), a negative lead ( 132 ), a positive pole ( 133 ), a negative pole ( 134 ), Batteries ( 135 ), a feather ( 136 ), a locking ring ( 137 ), a copper contact ( 138 ) and a stopper ( 139 ). Thereby, a power supply circuit is formed. The Power supply unit ( 13 ) is connected to the switching unit ( 14 ) and serves to supply a current to the light emitting diodes ( 12 ).

The shaft ( 6 ) at the front end of the handle ( 1 ) can be connected to any tool head. The handle ( 1 ) is at the rear end with a back cover ( 5 ) screwed.

2 shows the connection of the transparent screen ( 3 ) with the lid ( 2 ) and the handle ( 1 ). As shown, first grab the locking parts ( 15 ) at the front end of the handle ( 1 ) in the locking grooves ( 32 ) of the transparent screen ( 3 ) one. Then the locking ring ( 4 ) in the annular groove ( 22 ) of the lid ( 2 ) to clear the transparent screen ( 3 ) to fix.

How out 3 can be seen, the transparent screen ( 3 ), with the handle ( 1 ), two translucent curved surfaces ( 31 ) on. Through the switching unit ( 14 ) the LEDs can be switched on and off ( 1 ).

How out 4 can be seen, the transparent screen ( 3 ) curved surfaces ( 31 ) (in the present embodiment, two curved surfaces ( 31 ), wherein the upper curved surface ( 31 ) has a smaller curvature (ie a larger radius of curvature), whereby the illumination area is larger, so that the light intensity is lower, while the lower curved area ( 31 ) has a larger curvature (ie, a smaller radius of curvature), whereby the illumination area is smaller, so that the light intensity is higher.

By The two different light intensities can with the help of the invention both a larger lighting area as well as a higher one luminous intensity be achieved.

In summary It should be noted that the invention is characterized by the translucent screen, the more than two curved surfaces with different curvature has, surfaces with different light intensity be generated. The transparent screen is through the locking ring attached to the lid, so that the assembly and disassembly very much easy.
