DE102005044213A1 - Bracelet torch to illuminate fingertip manipulation in confined spaces has strap with link-fitting - Google Patents

Abstract

A bracelet bears an array of small lights that point towards the wearer's fingertips. The bracelet is formed by a strap with a link-fitting at the two ends. Each light source is located within a matching socket and is powered by e.g. a button battery.

Description

The The invention relates to a light ring.

to Targeted lighting of manipulation in places with insufficient own Lighting are known on the forehead mountable lights, which are the Illuminate the space in front of the head in a roughly straight line. A Peculiarity in the use of such head or headlights is in that two workers working with such luminaires come into contact with each other blind each other.

Of the Invention is based on the object to provide a way that allows several workers equipped with their own lamps to work together perform an assembly process, without being blinded by eye contact.

These Task is solved with a light ring according to claim 1.

Of the inventive light ring allows for example, when attached to the forearm, the targeted Illuminate the spot where the appropriate hand manipulates, where the worker can turn his head or change his direction, without the direction of illumination following the rotation of the head.

The under claims are on advantageous embodiments and further developments of the luminous ring according to the invention directed.

The The invention will be described below with reference to schematic drawings, for example and explained in more detail.

It represent:

1 a schematic perspective view of a light ring attached to the forearm behind a wrist,

2 a section through a lamp and

3 an embodiment of a light ring in the open state

According to 1 is a total with 10 designated light ring on a forearm 12 attached behind the wrist of a worker. The light ring 10 has an annular body 14 made of preferably flexible material, on the outer circumferential surface of a plurality of lights 16 is arranged at a mutual circumferential distance. The lights 16 Light rays are approximately parallel to the axis of the body 14 or the longitudinal extension of the forearm 12 off, leaving an assembly on which the hand is indicated - a thumb 18 and an index finger 20 the hand - manipulate. For example, hold the thumb 18 and the index finger 20 a screwdriver that turns a screw in or out.

Preferably, in the main body 14 of the light ring 10 an energy source 22 , For example, a battery integrated, which also has a base in the body 14 integrated switch 24 by means of the main body 14 integrated cables with the lights 16 connected is.

The lights 16 For example, are formed such that on the body 14 base 26 fastened or integrally formed with the base body, in each of which a light source 28 is used.

2 shows an example of a light source 28 , The light source 28 contains a lighting element 30 , For example in the form of an LED or light emitting diode, in a housing 32 is poured from transparent, preferably high refractive material. A light exit surface 34 of the housing 32 is curved so that that of the luminous element 30 radiated light in an appropriate manner approximately parallel, slightly divergent and slightly convergent emitted. The power supply lines 36 of the luminous element 30 are with corresponding, in the main body 14 connected to integrated lines.

3 shows an embodiment of a luminous ring 10 in open condition. The main body 14 of the light ring 10 contains an outer jacket 38 made of flexible material, such as plastic, in the in 3 not shown power supply lines for the lights 16 , the energy source 22 and the switch 24 are integrated. The coat 38 is with the exception of its end areas with a padding 44 provided whose thickness can be relatively large, so that is reduced with appropriate emission of light of the optionally isolated from the hand area. In the end area 40 is the coat 38 with the exception of protruding pimples 46 formed with a reduced thickness. The likewise formed with a reduced thickness end 42 has holes 48 on, in which the pimples 46 be clipped. In this way, the width of the luminous ring 10 adapted to different arm thicknesses.

The described light ring can be modified in many ways. The main body may for example be designed in the manner of a bracelet or as a closed ring, which is slipped over the wrist. With an open design of the basic body, its adaptation to different arm strengths can be followed by different closure mechanisms known per se. It is particularly advantageous in place of in 3 Pimples and holes shown to use a hook and loop fastener, the interlocking, but tear-off, for example, band-shaped parts are arranged on one end of the body. This allows a precise adaptation to any arm thickness.

The lights 16 need not be mounted in sockets, which is previously formed on the body. Rather, the lights can also be prefabricated units, which are each fastened to the base body, for example, glued to the base body. Because of the low energy consumption, the use of LEDs as light-emitting elements is particularly advantageous. Any other lighting elements may be used. The lighting element and the light bundling device do not necessarily have to be integrated. For bundling the light emitted by the luminous element prisms, lenses, reflectors or the like can be used.

The Energy supply does not have to be integrated into the light ring. Rather, an external power supply can be used for example, on the body is worn, for example, a battery or the like, with the light ring via lines connected is. The energy consumption of LEDs is so low that a supply of solar cells under buffering by means of a battery, or by means of a power generator, which uses the movement of the light ring is possible. In integrated Energy supply, for example by means of button cells, the body has advantageous a width larger than that Diameter of the button cell and at least in the area of the button cell a thickness that allows their secure recording.

Of the inventive light ring, which was described as a bracelet, especially during assembly work in confined spaces, for example the body assembly in the car manufacturing, are used. It It is understood that the light ring be designed so small can be pushed onto a finger or thumb.
