GLOVE FOR HANDLING FLEXIBLE OBJECTS WITH SOURCE

LUMINOUS, PARTICULARLY FOR SKIN CONTROL

The present invention relates to a glove for handling flexible objects, intended for visual inspection of the quality of the surface of these objects, in particular skins for the production of leather objects.

Skins prepared for the production of leather objects may require careful visual checks of the entire surface in order to detect defects, either to optimize the placement of the pieces to be cut according to the quality of the skin, or to sort the skins by level of choice.

It is possible to use a system comprising a grazing light source held in the hand, making it possible to scan the surface of the skin in order to obtain in all points a grazing light more easily highlighting the defects. But manipulating this system is inconvenient and time consuming, so this solution is only very rarely implemented.

In addition, the light source of these systems fixed on a finger poses a problem of difficulty in handling the skins, the movement of the fingers being hampered by this light source.

In addition, the light source comprising its optics fixed on a finger, is vulnerable, and can easily be shocked during movements of the hand, which causes failures. Regardless of this fragility, the power of the light source is too low to allow effective control in the illuminated area.

The object of the present invention is in particular to avoid these drawbacks of the prior art.

To this end, it provides a glove for handling flexible objects in order to visually check the quality of the surface of these objects, comprising a glove, and a light source intended to illuminate this surface, characterized in that the source light is attached to the glove at the palm of the hand.

An advantage of this handling glove is that the light source located in the palm of the hand, easily allows to obtain a grazing light by bringing this hand to the surface of the object, while freeing the fingers which can easily manipulate these objects.

The light source being far from the fingers, the movements of these fingers, in particular during the preemption of objects, are not likely to shock the light source and damage it.

The handling glove according to the invention may further comprise one or more of the following characteristics, which can be combined with one another.

Advantageously, the handling glove has a shape leaving fingers of the hand which are fully exposed. We facilitate the use of these fingers for manipulating objects.

In this case, in particular the glove may have an annular part intended to surround the base of the thumb, at least the index finger, the middle finger and the ring finger being uncovered.

Advantageously, the light source is fixed on the palm below the thumb.

Advantageously, the handling glove has on each side a curved notch formed opposite the fingers which are uncovered.

Advantageously, the light source comprises light-emitting diodes arranged on a flexible support. The flexibility of the support limits the discomfort of hand movements.

Advantageously, the handling glove comprises an electronic card for controlling the light source which is separated from this light source, and connected to this source by a flexible connection. A light source with the minimum number of elements can be produced in this way, which is very compact.

Advantageously, the handling glove comprises a battery for supplying the electronic card, which is separate from this electronic card.

Advantageously, the light source comprises holes receiving a fixing seam on the glove.

Advantageously, the handling glove comprises fabrics comprising polyamide and polyester. These fabrics have qualities of flexibility, robustness, and allow breathing of the skin.

Advantageously, the handling glove comprises a light source diffusing a light intensity of at least 1500lux on a circle of diameter 30cm.

The invention will be better understood and other characteristics and advantages will appear more clearly on reading the description below, given by way of example with reference to the appended drawings in which:

- Figures 1, 2 and 3 show a handling glove according to the invention arranged on one hand, presented successively from below, from the outside and from above;

- Figure 4 shows the electrical system of this handling glove;

- Figure 5 shows the surface illuminated by this handling glove; and

- Figures 6 and 7 show two handling gloves according to variants.

Figures 1,2 and 3 show a hand wearing a handling glove, successively comprising an inch 6, an index finger 8, a middle finger 10, a ring finger 12 and a little finger 14. By definition, the outer side of the hand is the side of the 6 inch, the underside is the side of the palm.

The handling glove comprises, towards the rear, a circular sleeve 22 covering the end of the forearm, extended by a part covering the palm 2 which ends in a first annular part 24 adjusted on the base of the thumb 6, and a second annular part 28 adjusted on the base of the little finger 14.

At the level of the index 8, the middle finger 10 and the ring finger 12, the two annular parts 24, 28 meet below the hand by a small curved notch 30 freeing about a quarter of the palm, and above of the hand by a large curved notch 32 freeing about half of the back.

An opening 26 having a curved outline is arranged on the outside of the glove at palm level, between the circular sleeve 22 and the first annular part 24.

A light source 40 is fixed on the glove in the palm of the hand, near the inside of this palm.

An electronic control card 44 fixed on the back of the glove, near the inner side, is connected by a flexible strip 42 to the light source 40 going around this inner side.

A battery 48 fixed on the back of the glove, in the middle of the circular sleeve 22, is connected to the electronic card 44 by an electric cord 46.

The fabrics forming the glove must in particular be very flexible so as not to hinder the movements of the hand, a breathing capacity to obtain exchanges, a comfort of contact with the skin, and a resistance to withstand wear.

The cuts made on the glove allow both good maintenance of the electrical system equipment, maximum hand clearance to avoid sweating problems, and ease of donning and doffing of this glove. Note that the glove does not have a closure system, which simplifies its manufacture.

Advantageously, the glove has an inner lining. The outer fabric may include a large part of polyamide and polyester, and a small part of elastane and polyurethane. These materials provide qualities of impermeability, breathability and elasticity. The inner fabric can comprise a major part of polyamide and a small part of spandex, these materials bringing a fine fabric pleasant to the touch, as well as qualities of elasticity and ease of cutting.

In addition, a micro-perforation can be made on the fabrics to increase the glove's breathing capacity.

FIG. 5 shows the lighting system comprising the light source 40 comprising a support made of flexible plastic material, having a rectangular shape having at each angle a hole 50 provided for attachment to the glove, in particular by sewing. In particular, the lighting system 40 has a width of around 1 cm, and a length of between 2 and 4 cm.

Fifteen light-emitting diodes 52 of the “LED” type (abbreviation of the English terms “light-emitting diode”), arranged in two rows, delivers lighting having an appropriate color temperature, which is advantageously close to that of the sun.

The electronic control card 44 formed in the same way by a flexible material comprising fixing holes 50, supports a sliding switch 54 allowing the operator to switch on and off the light source 40, and supports the necessary electronic circuits for checking the diodes 52. The electronic card 44 substantially forms a square of approximately 3 cm on one side.

The flexible strip 42 comprising electrical connections connecting the light source 40 to the electronic card 44, as well as this light source and this electronic card have a flexibility allowing them to remain pressed against the glove during movements, without hampering these movements during handling. operator.

The battery 48 comprising electrochemical cells rechargeable by a charger connected to the building's power supply network, is connected to the electronic card 44 by the flexible cord 46 comprising a connector 56 allowing this battery to be disconnected, in particular for exchanging it.

FIG. 5 presents the optimum lighting with a grazing light with a circular surface of diameter 30 cm, delivered by the light source 40, which brings to the center B of this surface a minimum light intensity of 2000lux, and on the edges A a minimum intensity of 1500lux.

In these conditions, both high working comfort and a quality of surface control which is ensured are obtained.

FIG. 6 presents a glove similar to that presented in the previous figures, comprising above the hand the large notch 32 and below the small notch 30 which are arranged opposite the index finger 8, the middle finger 10 and the ring finger 12.

The glove has the first annular part 24 adjusted on the base of the thumb 6, and the second annular part 28 adjusted on the base of the little finger

14. This glove does not have an opening 26 on the outside.

The light source 40 is fixed on the glove in the palm of the hand, 5 near the outside of this palm, under the thumb 6.

In this way the operator can place the inner side of the hand on a skin, the light source 40 being slightly in height, delivering a grazing light on this skin. Skin control is then more comfortable.

FIG. 7 presents a glove similar to that presented in FIG. 6, not comprising on the base of the little finger 14 of the second annular part. There is thus obtained both good resistance of the light source 40 located on the side of the thumb 6, and a greater clearance of the hand which facilitates the handling of the skins, and prevents overheating.
