FR2521408A1 - Electrically heated suitcase skiers - uses electric heating element, operable from either mains or automotive supplies, built into walls of case - Google Patents

Abstract

One or more of the walls (2,5) of the case (1) contains an electric heating element (7) placed between the outer protective face (23) and the inner, insulated, lining (3). The electric elements are suitably arranged to be operable from either 12/24V automotive electric supply systems or from electric supply mains (110/220V), and appropriate connectors (10,11) are provided on cables (8,9) connected to the heating elements. An enclosure (14) is provided in the side of the case to provide storage for these cables and plugs. The case is particularly applicable to skiers and associated services.

Description

 The invention relates to a bag or suitcase having thermal insulation on all sides.

 Insulating bags, which are used either to keep drinks cool or to keep food warm, are known in many forms. These bags are only suitable for keeping the heat or cold of hot or cold objects, heat exchange with the environment, occurring more slowly than if the objects were kept out of the bag.

 With known bags or suitcases of the species mentioned above, it is therefore only possible to slow down the temperature variations of the objects kept in the bag or suitcase. On the other hand, it is not possible to maintain these objects at a determined temperature or to heat cold objects introduced into the bag to a prescribed temperature.

In particular, for ski boots intended for cross-country skiing or downhill, it appeared to be extremely important from the medical point of view, not only to protect them before use against extreme cooling, but to put them on as much as possible in the preheated state. For convenience, these shoes are only put on immediately before the start of the ski tour. so the muscle system.
The lower tendons and ligaments of the foot and the extremity / body are strongly cooled, which, when skiing, easily leads to injuries, for example fractures, distortions or sprains.

That is why, precisely for competition - but also for the amateur sportsman who, as experience shows, does not warm up sufficiently beforehand - it is particularly advisable to put on preheated ski boots, for reasons medical in order to avoid lesions of the lower extremities.

 The object of the invention is to give a bag or a suitcase of the species indicated at the start a structure such that not only is pocketed the cooling, for example, of ski boots which are introduced therein, but gu ' in addition, a predetermined temperature is ensured, not only at rest, but also during the journey by car.

 This problem is solved according to the invention by the fact that in one or more of the interior walls of the bag or of the suitcase is arranged, between the insulation and the lining situated inwards, an electric heating device, that each heating device is designed to operate on 12/24 or 110/220 V, that each heating device leads two connection conductors which are provided with plugs or sockets for connection to the network of 1-2 / 24 V d 'a motor vehicle or to the distribution network and the dimensions of the bag or suitcase are chosen so that they can accommodate ski boots, skates etc.

 Thus, the bag or suitcase according to the invention is provided with heating devices which are designed both for the operating voltage of the car and for the voltage of the household network. Thus, before starting the journey for skiing, you can heat the bag at sci on the network, so that the ski boots already have the desired temperature.

Then, during the journey to the ski slope, the heater of the bag or suitcase is connected to the on-board network of the car and the temperature chosen in advance, determined by the heating, is maintained at inside the bag. At the places where skiing is practiced, the skier then has a preheated boot which greatly reduces the risk of injury.

 The heating device for the bag is designed so that even when the ski boots are cold, heating, both in the car and on the public network, lasts only a few minutes.

An exemplary embodiment of the invention is described more precisely below in connection with the drawings in which z
Figure 1 shows a suitcase designed according to the invention
FIG. 2 a section of the closed suitcase according to FIG. 1,
FIG. 9 shows in perspective a bag designed according to the invention and
Figure 4 is a section through a side wall.

Figures 1 and 2 show a suitcase 1 according to the invention, provided on all sides with insulation 3. The suitcase 1 can Besides closed by a cover 2 which also has heat insulation 3. In addition, the side walls
Rales 4 are also isolated on all sides.

 In the cover 2 and in the bottom 5 are provided respective heating coils 6,7 provided with connection conductors 8,9 having plugs 10,11.

 The heating coil 6 arranged in the cover 6 is designed for 12/24 V. Correspondingly, the plug 10 is also designed so that it can fit into sockets provided in the car.

The second heating winding 7 is designed for connection to 110/220 V so that a European plug or a standardized plug adapted to the sockets of the country in question is placed here. The heating coils are designed so that when the cover 2 is closed, they heat the interior of the case 9 to a predetermined level. The insulation is chosen so that at a determined temperature, the heat losses are equal to the heating power supplied, so that in the simplest case, one can do without a separate temperature setting.

 On a side wall of lawalise 1, opposite the handle 13, is arranged a rack 14 which serves to receive the connection conductor 8.9 which is not needed, with the corresponding plug 10.11. In the same wall, which normally stands on the bottom, are arranged two water discharge openings, intended to allow the thaw water possibly coming from ski boots, to flow outwards .

 Figure 3 shows in perspective a bag designed according to the invention. This bag is fitted with a strap 17 and can be closed by means of a zipper 18.

In the opposite side walls 19 and 20 are arranged heating coils 21 which are again designed for 12/24 and for 110/220 V. These heating coils are i again provided with corresponding connection conductors 8.9 as well as plugs 10.11. On the side wall is arranged a locker used to house the connection doctors 8,9 and in the bottom, openings for evacuation of any thaw water.

 The wall structure of a suitcase or bag according to the invention is indicated in FIG. 4. Outside is a protective sheet 24 which can be colored in the usual way or receives an advertising impression. Following this protective sheet is the insulation 3. Inwardly, the wall is provided with a coating 23. Between the coating 23 and the insulation 3 is disposed the heating coil 6 which is used for heating. iron the inside of the bag or avalise.
