CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application is the United States national phase of International Application No. PCT/FR2012/051588 filed Jul. 5, 2012, and claims priority to French Patent Application No. 1156377 filed Jul. 13, 2011, the disclosures of which are hereby incorporated in their entirety by reference. 
     FIELD OF THE INVENTION 
     This invention concerns a removable handle for a cooking pot. 
     The removable handles are used to grip cooking pots such as casseroles or frying pans. The removable handles may be quickly attached to the cooking pot when in use and be removed from the cooking pot to make it easier to store. 
     DESCRIPTION OF RELATED ART 
     Document DE 102007054022 discloses a removable handle for a cooking pot which includes a side wall. The handle includes a grip body, a mechanism to attach it to and remove it from the cooking pot, a display and an energy source. More specifically, the attachment mechanism can be connected to an intermediate part attached to the pot. The pot includes a temperature sensor connected to a display by a wired connection. The pot includes electrical contacts which can be connected to and disconnected from the electrical contacts in the handle. 
     However, the removable handles of the prior art as described below present problems during cleaning. These handles are difficult to wash in water. The presence of a battery-powered energy source requires a housing in the grip body to hold the energy source and a removable cover to reseal the housing. This arrangement allows the cover to be removed to change the battery. However, water in the housing may result in short-circuits and damage the electronics. 
     EP-A-132910 also discloses a handle for a cooking pot which includes a side wall, wherein said handle includes: 
     a grip body, and 
     a mechanism to attach it to and disconnect it from the cooking pot. 
     The attachment mechanism includes a screw. This screw is mounted between the grip body ( FIG. 2 ) and the attachment support ( FIG. 3 ), which is part of the pot. 
     EP-A-132910 proposes an electromagnetic connection mechanism connected to a rechargeable electrical energy source and positions the electrical mechanism ( FIGS. 5-9 ) in a connected attachment support ( FIG. 3 ). 
     When the section of the handle, which is separable from the attachment support which is part of the pot, is actually disconnected from this support, there is no problem with respect to watertightness of the handle. However, the invention is designed to provide a removable handle which may be washed in water while avoiding the inconvenience in this area with the prior art. 
     In this regard, the problem of the invention related to the watertightness of the handle due to the rechargeable electrical energy source housed in the removable section of the handle does not exist in EP-A-132910 since unscrewing the aforementioned screw is not part of the normal operation of the item, in contrast to the invention with its removable handle. 
     In other words, the prior art provides that the electrical and/or electromechanical mechanism will be separate from [the removable section of] the handle. 
     SUMMARY OF THE INVENTION 
     To overcome the aforementioned difficulties, it is proposed here that the handle, which therefore is removable in addition to the grip body and said attachment mechanism, consist of:
         an electrical and/or electromechanical mechanism housed in the grip body,   a rechargeable electrical energy source which provides electrical current to the electrical and/or electromechanical mechanism, and   an electromagnetic connection mechanism to connect the rechargeable electrical energy source to an electrical power source which is external to the handle to recharge the rechargeable electrical energy source.       

     “Electromagnetic connection mechanism” means a connection method which may be either electrical or magnetic. 
     Accordingly, the invention provides a removable handle which is more easily cleaned in water. The use of a rechargeable electrical energy source which does not have to be replaced simplifies the design of the handle while eliminating items which must constantly be removed to change the battery. This improves the watertightness of the handle.

     DESCRIPTION OF THE INVENTION 
     As shown in  FIG. 8 , removable handle  1  includes grip body  7 , attachment mechanism  2  which can be connected to and detached from cooking pot  3 , an electrical and/or electromechanical mechanism  5  housed in the grip body  7 , a rechargeable electrical energy source  6  which provides electrical current to the electrical and/or electromechanical mechanism  5 , and electromagnetic connection mechanism  8  connected to rechargeable electrical energy source  6  and which can be electrically connected to external electrical power source  16  and the handle to recharge rechargeable electrical energy source  6 . Attachment mechanism  2  is mounted on grip body  7 . They preferably include, as shown, a section attached to it and a section which move relative to it, although it forms part of said body. 
     In one possible implementation, grip body  7  does not include a cover to access rechargeable electrical energy source  6 . Grip body  7  includes two envelopes  41   a  and  41   b  attached to one another by attachment mechanism  42 , which could be a screw, as shown in  FIGS. 1 and 8 . These envelopes seal off rechargeable electrical energy source  6  and have no opening or cover to remove it. 
     Grip body  7  may include watertightness means  43  to ensure that rechargeable electrical energy source  6  is watertight. 
     Watertightness means  43  may include a joint between two envelopes  41   a  and  41   b  (not shown). 
     In another possible implementation shown in  FIG. 11 , grip body  7  may include housing  45  to accept rechargeable electrical energy source  6 . This housing  45  is watertight. It is closed by cover  44 . Watertightness means  43  includes joint  43  located between cover  44  and the external peripheral edge which surrounds housing  45 . Joint  43  may be a flat joint. 
     In another possible implementation shown in  FIG. 12 , rechargeable electrical energy source  6  is incorporated into the material which forms grip body  7  when it is molded. 
     In one possible implementation shown in  FIG. 3 , external electrical power source  16  consists of coil  16  which recovers electrical energy. Electromagnetic connection mechanism  8  of handle  1  includes at least one terminal  10  and  10 ′ designed to come into contact with at least one additional terminal  11  and  11 ′ designed to be connected to cooking pot  3  and connected to external electrical power source  16 . 
     Pot  3 , as shown in  FIGS. 2 and 4 , may include at least one electrical generating coil  16  using magnetic flow produced by an induction heating mechanism. This magnetic flow powers electrical and/or electromechanical mechanism  5  of handle  1 . Coil  16  is located on external surface  14   b  of bottom  9  of pot  3 , or preferably elsewhere, in particular, on internal surface  14   a.    
     Preferably, coil  16  is silk screened to create a silkscreened path. The silkscreened path includes at least one electrical conductive material. 
     Advantageously, coil  16  is located on external surface  14   b  of bottom  9  of pot  4 , to be near the surface of induction heating mechanism  15 , with no magnetic screen between them (a PTFE or enamel layer may be used, neither of which forms such a screen). 
     Each connection terminal  10  and  10 ′ can be electrically connected to at least one additional terminal  11  and  11 ′ located on pot  3  which is connected to coil  16 . 
     Attachment mechanism  2  includes contact surface  12  designed to come into contact with additional contact surface  13  on pot  3  to ensure that handle  1  is attached to pot  3 . Contact surface  12  of attachment mechanism  2  has at least one terminal  10  and  10 ′. Attachment mechanism  2  includes two bits  2   a  and  2   b  which form a pincer and move relative to one another to attach handle  1 . One of two bits  2   a  and  2   b  includes at least two terminals  10  and  10 ′. 
     Two bits  2   a  and  2   b  pinch wall  4  of pot  3  on which at least one additional terminal  11  and  11 ′ is located. Each terminal  10  and  10 ′ of handle  1  contacts this additional terminal  11  and  11 ′. 
     The two bits  2   a  and  2   b  form a pincer which includes fixed bit  2   b  and mobile bit  2   a  relative to grip body  7 . Terminals  10  and  10 ′ may be located on fixed bit  2   b , as shown in  FIGS. 1 ,  3  and  5 . Preferably, fixed bit  2   b  consists of front section  17  of grip body  7  which contacts external surface  14   c  of the wall of pot  3 . In this implementation, coil  16  is located on external surface  14   b  of bottom  9  of pot  3 . 
     In another possible implementation (not shown), terminals  10  and  10 ′ may be located on the removable bit  2   a . In this implementation, coil  16  is located on surface internal  14   a  of bottom  9  of pot  3 . 
     In another possible implementation shown in  FIG. 14 , the handle has a mechanical attachment mechanism as, for example, described in application EP-1991098. Other mechanical attachment mechanisms may also be used. 
     To move mobile bit  2   a  with respect to fixed bit  2   b  located on the face, slide  60 , which is mounted in longitudinal direction  61  compared to body  7 , and first and second pivoting connecting rods  62  and  63 , is used. The second connecting rod acts directly on mobile bit  2   a . Maneuver button  64  mounted to shift on body  7  controls second connecting rod  63  and, through the articulated chain  60 ,  62  and  63  through lug  65  passes a light across rod  66  which ends on bit  2   a . More details are available in EP 2007260. 
     In this example, fixed bit  2   b  includes two terminals  10  and  10 ′, one lower terminal  10  of which is designed to come into contact with additional initial terminal  11  of the pot formed by electrical connection  19   a  located on side wall  4  of the pot and upper terminal  10 ′ designed come into contact with extremity  53  of curved edge  30  of the pot which thus forms second additional terminal  11 ′ of the pot. Coil  16  includes extremity  18   a  which comes into contact with a metallic layer which forms the pot. Accordingly, current may pass through this metallic layer to extremity  53  of curved edge  30 . 
     Lower terminal  10  of the pot is located near the lower wall of grip body  7 . Grip body  7  includes housing  54  located between contact surface  12  of fixed bit  2   b  and mobile bit  2   a . Housing  54  is designed to accept extremity  53  of curved edge  30  of the pot. Upper terminal  10 ′ is located in this housing  54  to contact extremity  53  of curved edge  30  of the pot. 
     This implementation, which is valid for a mechanical attachment mechanism, is also valid for an electromechanical attachment mechanism. 
     Rechargeable electrical energy source  6  may be a large battery or a super capacitor housed within grip body  7 . It may be electrically connected both to coil  16  to recharge it with electrical energy and to electrical and/or electromechanical mechanism  5  to power it. For example, the large battery may provide 3 or 6 volt current and 780 milliamp/hour capacity. 
     In one possible implementation, coil  16  includes an open loop and two extremities,  18   a  and  18   b , each connected to electrical connection  19   a  and  19   b  fixed on side wall  4  of pot  3 . Electrical connection  19   a  and  19   b  reach the area near upper edge  20  of side wall  4  and form additional terminal  11  and  11 ′ of pot  3  which may be connected to one of terminals  10  and  10 ′ of handle  1 . 
     In accordance with the implementation shown in  FIG. 2 , two electrical connections  19   a  and  19   b  are attached to external surface  14   c  of side wall  4  of pot  3 . Two electrical connections  19   a  and  19   b  are basically rectilinear, perpendicular and adjacent to bottom  9  of pot  3 . Handle  1 , or more specifically, fixed bit  2   b  then includes two terminals  10  and  10 ′ which can be connected to electrical connections  19   a  and  19   b  and be generally aligned parallel to bottom  9  when the handle is attached to the pot ( FIG. 1 ). Therefore, the handle may be attached to the pot and its height may be adjusted slightly. 
     In one variation, two electrical connections  19   a  and  19   b  may be curved. 
     In accordance with the implementation shown in  FIGS. 3 and 4 , each electrical connection  19   a  and  19   b  consists of peripheral section  21   a  and  21   b  surrounding side wall  4  and intermediate section  22   a  and  22   b  which connects peripheral section  21   a  and  21   b  to one of extremities  18   a  and  18   b  of coil  16 . Peripheral sections  21   a  and  21   b  are remote from one another. This distance is preferably as small as possible to not reduce maximum transmitted power. In this case, handle  1 , or more specifically fixed bit  2   b , includes two terminals  10  and  10 ′ which can be connected to peripheral sections  21   a  and  21   b , respectively, and aligned in non-parallel directions on bottom  9  of pot  3  ( FIG. 5 ). In the example in  FIG. 5 , two terminals  10  and  10 ′ are aligned vertically and perpendicularly on bottom  9  which is flat and horizontal. Peripheral sections  21   a  and  21   b  are circular. They may also be ovoid or have another shape. 
     Peripheral sections  21   a  and  21   b  are separated by space  38 , which is preferably constant ( FIG. 4 ). It may be variable. This distance is preferably the smallest possible to not reduce the maximum transmitted power. 
     Peripheral sections  21   a  and  21   b  are close to edge  20  of pot  4 . It is therefore possible to position handle  1  anywhere along the periphery of side wall  4 . No predetermined position exists. This is helpful when pot  3  becomes hot. It is not necessary to move or turn a badly positioned pot to attach the handle. The risk of a burn is avoided. Further, when a location on peripheral section  21   a  and  21   b  is dirty or damaged, it is possible to connect handle  1  at another location. In one variation, bottom  9  may include multiple coils  16 , each consisting of two extremities  18   a  and  18   b . For example, if bottom  9  includes two coils  16 , the handle may include four terminals which can be connected to the four terminals located on the wall of the pot (not shown). 
     In one variation, when bottom  9  includes two coils  16 , the handle may only include two terminals  10  and  10 ′. By positioning the handle differently relative to the pot, it is possible to connect the handle&#39;s terminals to either coil. The coils may be positioned in series or in parallel. In this case, electrical connections  19   a  and  19   b  and additional terminals  11  and  11 ′ are located on the pot surface to form only two additional terminals  11  and  11 ′. 
     The number of loops or spires depends on the energy consumption of electrical and/or electromechanical mechanism  5  to be powered. For example, an LCD display screen requires 100 mW and a motor to drive mobile bit  2   a  of the fixation means requires 6 W. Therefore, a single loop to recover 20 W is necessary. 
     In one possible implementation, terminals  10  and  10 ′ of handle  1  are electrical contact plates  23  pushed by elastic recall means  24 , as shown in  FIGS. 6 and 7 . They limit contact resistance to less than 100 mOmhs and, preferably, to less than 10 mOmhs, thereby significantly improving yield. 
     Each electrical contact plate  23  is elongated in shape and has a circular cross section. Each electrical contact plate  23  has a cross section of at least 0.75 mm 2  to resist a current of at least 0.5 A, and preferably 3 A. 
     Each electrical contact plate  23  includes head  26  on one of its extremities which is designed come into contact with terminal  11  and  11 ′ of pot  3  and, more specifically, with electrical connection  19   a  and  19   b  of pot  3 . This head  26  is preferably rounded or convex. 
     Each electrical contact plate  23  is located in cylindrical support  39  and can move relative to support  39  between a deployed position, in which electrical contact plate  23  is not in contact with a terminal ( FIG. 6 ), and a retracted position, in which electrical contact plate  23  is in contact with it and compressed against terminal  11  and  11 ′ of pot  3  ( FIG. 7 ). 
     Support  39  includes a housing in which spring  24  is located surrounding the central section of the plate. Spring  24  transfers a force to the exterior and against the lower section of head  26  of electrical contact plate  23 . This spring  24  is pushed against the bottom of support  39 . Electrical contact plate  23  includes foot  40  on its other extremity which is located on the outside of support  39 . Foot  40  abuts external support surface  39  when plate  23  is in the deployed position ( FIG. 6 ). Head  26  of the plate is also located on the outside of support  39 . Head  26  abuts forward support surface  39  when plate  23  is in the contracted position ( FIG. 7 ). Accordingly, plate  23  can move relative to support  39  when it is supported by it. 
     The assembly formed by plate  23 , support  39  and spring  24  is supported on fixed bit  2   b  of the handle, i.e., by forward section  17  of grip body  7 . Head  26  of the plate protrudes from surface  12  of fixed bit  2   b  when plate  23  is in the deployed position ( FIG. 6 ). 
     When pot  3  is placed on an induction plate, the inductor of the induction plate generates a magnetic flow which is captured by pot  3 , which then heats. A portion of the energy is recovered by coil  16  and used to power an electrical and/or electromechanical mechanism and/or rechargeable electrical energy source  6 . Therefore, the current induced in this coil generally alternates with a frequency of approximately 25 KHz. A rectifier and a filtering means may be provided. A current regulator may also be provided. These items are housed in handle  1 . A condenser may be provided to control the resonance system and maximize energy transfer. 
     Handle  1  may include command mechanism  27  to control operation and stop electrical and/or electromechanical mechanism  5 , as shown in  FIG. 8 . This command mechanism may include motor  28  and trigger mechanism  29  driven by motor  28 . Trigger mechanism  29  is designed to control mobile bit  2   a.    
     In one variation, the attachment mechanism may be mechanical and include hooks which are part of handle  1  and designed to be inserted into the openings provided on the side wall of the pot. Other attachment mechanisms are also possible, e.g., a nut-bolt system. In this case, electrical and/or electromechanical mechanism  5  may include a display or a brush activated by motor  28 , for example. 
     The attachment mechanism may be attached to side wall  4  of pot  3  or to another section of the pot such as a bracket which is part of the side wall. 
     Grip body  7  is elongated and extends in longitudinal direction (X). 
     In one variation, the two bits  2   a  and  2   h  which form pincer may move in opposite directions along longitudinal direction (X). 
     The handle is designed to be attached to and removed from pot  3 , which is a cooking pot (casserole, frying pan, etc.) Lateral wall  4  may form curved edge  30  on its upper section, which forms a pouring edge. The example in  FIGS. 3 and 8  shows side wall  4  which includes edge  30  curved toward the exterior. Fixed bit  2   b  is formed by grip body  7 . More specifically, grip body  7  includes forward section  17  which has a contact surface which is designed to come into contact with external surface  14   c  of side wall  4  of pot  3 . The contact surface of forward section  17  of the body is shaped to complement that of external surface  14   c  of side wall  4  and, more specifically, of the external surface of curved edge  30  of pot  3 . More particularly, the contact surface of forward section  17  of grip body  7  has flat section  31  which runs along section curved  32  to the interior of grip body  7 . Grip body  7  is preferably made of bakelite. When removable handle  1  is attached to pot  3 , it is basically perpendicular to a plane tangent to side wall  4  of pot  3 . Mobile bit  2   a  is shaped to complement that of internal surface  14   d  of the side wall and, more specifically, the surface internal of curved edge  30  of pot  3 . 
     In one variation, two bits  2   a  and  2   b , which form a pincer of handle  1 , may be designed to be attached to a straight side wall without a curved edge, as shown in  FIGS. 2 and 4 . 
     Mobile bit  2   a  is extended by sliding arm  33  in a slide in grip body  7 . Arm  33  extends in longitudinal direction (X). It is flat. In one variation, motor  28  may be replaced, for example, by an electromagnet, servomotor, or a pneumatic or electrical jack. 
     Electrical motor  28  is provided with electrical current by electrical energy storage mechanism  6  and/or coil  16 . Electrical motor  28  has shaft  34  which rotates. Preferably, electrical motor  28  includes a reduction gear. The rotation speed of electrical motor  28  should be least 340 rotations per minute, and preferably 360 rotations per minute. The motor couple should be at least 80 mN/m and preferably 100 mN/m. 
     Trigger mechanism  29  includes initial transmission mechanism  35  designed to transfer the rotating motion of electrical motor  28  to second transmission mechanism  36 , which is part of mobile bit  2   a  to move mobile bit  2   a  between the open and closed positions. 
     In one possible variation, initial transmission mechanism  35  includes threaded rod  35  which is rotated by electrical motor  28 . Second transmission mechanism  36  includes mobile item  36  which has a threaded opening which engages threaded rod  35 . The rotation of threaded rod  35  moves mobile item  36  the length of it and, as a result, moves mobile bit  2   a  between the open and closed position. Threaded rod  35  may be an infinite threaded screw. Threaded rod  35  is connected to shaft  34  of electrical motor  28 . Threaded rod  35 , shaft  34  and bit  2   a  and  2   b , which form a mobile pincer, are generally aligned in a longitudinal direction (X). Threaded rod  35  rotates but does not move. 
     Threaded rod  35  and the threaded opening of mobile item  36  has a thread width of between 0.65 mm and 0.85 mm to block movement of mobile bit  2   a  when it is in closed position. Preferably, the thread is 0.75 mm wide. 
     For example, to provide 10 mm of travel of mobile bit  2   a  between the closed and open position to create a 10 mm of transverse movement of mobile item  36  along threaded rod  35 , motor speed is 360 rotations per minute and the thread width of threaded rod  35  and the threaded opening of mobile item  36  is 0.75 mm. This configuration allows the movement of mobile bit  2   a  to be effectively blocked when it is in the closed position. Mobile item  36  may be, for example, a nut. 
     In one variation, trigger mechanism  29  may include a gear system (rack-and-pinion, conical wheels or cylinders), a bearing system (screw bearings), pulleys, belt, cog, chain, friction transmission or scotch yoke/cam system. 
     Mobile bit  2   a  may be made, for example, from stainless steel. Mobile bit  2   a  is extended by rectilinear arm  33  which forms a slide and extends to the interior of grip body  7 . This arm  33  slides into a housing in grip body  7  between the closed and open position of mobile bit  2   a . Second transmission mechanism  36  and, more specifically, mobile item  36  is part of this arm  33 . In the examples shown, mobile item  36  is attached to arm  33 . 
     Removable handle  1  may include switch  37  accessible from the exterior of grip body  7  to manually select the direction of rotation of electrical motor  28 . An initial direction of rotation opens mobile bit  2   a . A second direction of rotation closes mobile bit  2   a . For example, when the direction of rotation to close mobile bit  2   a  is initially selected with switch  37 , pushing command button  27  rotates electrical motor  28  in that direction of rotation and the closing direction of mobile bit  2   a.    
     In one variation, removable handle  1  may include a sensor to detect the presence of handle  1  in contact with or very near pot  3 . Activating the switch may automatically close mobile bit  2   a  without user intervention. 
     In one possible implementation, electrical and/or electromechanical mechanism  5  may include mechanisms other than the attachment mechanism. It may include a rotating brush connected to a shaft driven by the electromechanical mechanism or an agitator to, for example, blend, crush or mix the food. In this implementation, handle  1  includes an attachment mechanism which may be triggered manually or electromechanically. 
     In one possible implementation (not shown), the electromechanical mechanism may include a cam rotated by the threaded rod. The cam is part of the threaded rod and is located near the forward end of the threaded rod. The cam is housed in a housing in grip body  7 . The housing opens to the exterior on the upper face of grip body  7 . The cam is rotated by electrical motor  28  so it moves between a rest position in which the cam is housed in the housing and an activated position in which the cam protrudes from the upper face of handle  1 . In the rest position, the main axis of the cam is basically parallel to the horizontal plane of handle  1 . In the activated position, the main axis of the cam is basically perpendicular to the horizontal plane of handle  1  and oriented upward when handle  1  is attached to pot  3  when it is placed on a horizontal surface. In this activated position, the cam protrudes from the upper face of handle  1  and allows the edge of a cover placed on pot  3  to be raised more or less to control the rate of vapor flow when food is heated in pot  3 . 
     In one variation, the electromechanical mechanism may include a cog rotated by the threaded rod which is itself driven by electrical motor  28  (not shown). The cog which is part of the threaded rod and is located near the front end to the threaded rod. The cog is housed in a housing in grip body  7 . The housing opens to the exterior on the upper face of grip body  7 . The cog is rotated by electrical motor  28  to drive a trammel located on the cover. The trammel rotates a paddle to blend the food (for example, purée, fried vegetables, or soup) in the bottom of pot  3 . 
     In one variation, handle  1  includes a lifting mechanism to raise a cover placed on a pot (not shown). 
     Electrical and/or electromechanical mechanism  5  may include a display powered by electrical energy storage mechanism  6  and/or coil  16 . This display may include a liquid crystal screen to, for example, display the remaining power in the electrical energy source, time, remaining cooking time or temperature of the pot. The liquid crystal screen is located on the upper face of handle  1 . 
     Electrical and/or electromechanical mechanism  5  may include a measurement mechanism such as a temperature sensor or mechanism to weigh the food contents in pot  3 , for example. The temperature or weight may be displayed on the liquid crystal screen. Handle  1  may include a clock and timer. The measurement mechanism is powered by electrical energy storage mechanism  6  and/or coil  16  and is connected to the electronic circuit. 
     Electrical and/or electromechanical mechanism  5  may include a wireless communication mechanism to receive and/or transmit information to a base station. The communication mechanism may include a radio transmitter and/or receiver powered by electrical energy storage mechanism  6  and/or coil  16  and is connected to the electronic circuit. For example, the base station may transmit cooking recipes to handle  1 . These recipes can be displayed on the liquid crystal screen. Handle  1  may transmit signals with the pot temperature to the base station. 
     Electrical and/or electromechanical mechanism  5  may include a lighting mechanism, such as, for example, a diode, to light the food in pot  3 . The lighting mechanism is located on the upper face and in front of handle  1 . The lighting mechanism is powered by electrical energy storage mechanism  6  and/or coil  16 . 
     The foregoing variants are possible for a handle attached permanently to pot  3  or to one which is removable. 
     An electronic card or circuit may control, for example, the rotation direction of the motor, detect the tightening of mobile bit  2   a , display information on the status of handle  1  (open/closed, remaining power, specific problems, etc.), and the battery charge. 
     Electromagnetic connection mechanism  8  is accessible from the exterior of removable handle  1  to recharge rechargeable electrical energy source  6 . 
     Electromagnetic connection mechanism  8  may include “jack” type female socket  46 , as shown in  FIG. 9 . This female socket  46  is located on grip body  7  of removable handle  1 . It may be located on the side wall of grip body  7 . Female socket  46  is may be connected to the sector using a power cord which includes a “jack” type male plug designed to be inserted into female socket  46  of removable handle  1 . 
     As shown in  FIG. 9 , electromagnetic connection mechanism  8  may include two electrical connection terminals  47   a  and  47   b  which can be connected to and disconnected from two additional electrical connection terminals  51   a  and  51   b  on recharging stand  50  shown in  FIG. 13 , to recharge electrical energy source  6 . Electrical connection terminals  47   a  and  47   b  are located on the back face of removable handle  1 . Electrical connection terminals  47   a  and  47   b  may be connection plates or contacts. Removable handle  1  may be placed on recharging stand  50  in a basically vertical position or inclined from the vertical when recharging stand  50  is placed on a horizontal surface. Recharging stand  50  is connected to the electrical grid (230 V for example). 
     In one variation shown in  FIG. 10 , electromagnetic connection mechanism  8  may include secondary induction coil  47  connected to the rechargeable electrical energy source, as shown in  FIG. 10 . Secondary induction coil  47  is designed to accept the electromagnetic flow generated by primary induction coil  48  provided for on recharging stand  49 . 
     Grip body  7  includes cavity  52  leading to its external surface. Cavity  52  is surrounded by secondary induction coil  47 . Secondary induction coil  47  is housed inside grip body  7 . Cavity  52  is designed to accept primary induction coil  48  of recharging stand  49 . The transfer of energy from primary induction coil  48  to secondary induction coil  47  takes place without any contact. Cavity  52  forms a blind hole in grip body  7 . It is bordered by a circular wall and a bottom. Secondary induction coil  47  surrounds external surface of the circular wall. These magnetic connection mechanisms ensure the watertightness of grip body  7  and form a watertight connection mechanism.
