    ELECTRIC RELEASER FOR QUICK FIRE MAIL
    FIELD OF THE INVENTION The invention relates to an electrically operated winding device for an express fire reel as defined in the preamble of protective claim 1.
    BACKGROUND OF THE INVENTION Emergency fire hydrants are part of the property's initial fire extinguishing equipment. They are installed especially on properties with a large number of people, flammable materials or a high risk of fire. For example, hotels, hospitals, shopping malls, schools, industrial properties. The property's fire safety equipment must be inspected and maintained regularly. Emergency fire hydrants do not have an electric retractor.
    Fast fire reels are often installed, for example, in shopping malls at a height of approx. 2-3 m from the floor level. The end of the hose is brought lower, so that the hose can be unloaded from the reel directly by pulling the hose off the floor level. However, rewinding in these cases takes place from the top of the reel and a hoist is required for the job.
    OBJECT OF THE INVENTION The electric winder is intended to allow the hose to be rewound directly - from the floor level, after inspection or use, without the necessary racks.
    SUMMARY OF THE INVENTION Rewinding is possible by means of an electrically operated winding device by pulling the belt and guiding the hose with one hand without the necessary racks. The - electrically operated - winding device - rapid fire reel according to the invention = is characterized by what is stated in protection claim 1. Other features of the invention are characterized by what is stated in other protection claims. o 35 O The electric - winding device - comprises a roller arranged to be attached A in the vicinity of the quick - release reel = and arranged to press against the fast - running reel during winding. In addition, the winding device comprises an electric motor connected to the roller so that 2 it rotates the roller when it is running. In addition, the winding device comprises a belt connected to the electric motor so that pulling on it starts the electric motor. a a LO The roll is preferably made or coated with a material whose coefficient of friction 2 allows the rotational movement of the roll to be transmitted to the quick-release coil by means of friction. S Possible materials include rubber, silicone. N 45 N In one embodiment of the invention - a tension limiter spring is attached to the belt. The tension spring limits the force that is transmitted through the belt. According to a preferred embodiment, the roller is attached to a frame which is divided in the longitudinal direction into two parts, a first part and a second part. There is an anchorage point at or between the parts around which the frame can move. In this embodiment, the roller and / or the motor are attached to the first part, for example, and the belt to the second part, respectively. In this embodiment, the body is positioned under the spool so that by pulling down from the belt, the spool moves upwards until it contacts the spool.

Rewinding begins Figure 6. The reel roller catches on the fast fire reel. The force is transmitted based on friction Figure 7. DETAILED DESCRIPTION OF THE INVENTION An embodiment of a winding device according to the invention for a rapid fire reel is shown in Figure 7. The invention is illustrated in Figure AND perpendicular to the direction of the mounting plane, and in Figure 7B parallel to the mounting plane. The quick fire coil 10 comprises a hose (not shown) and a quick fire coil 10 around which the hose is wound. The winding device 20 comprises at least a roller 22, a motor 24 and a belt 26.
    The winder is positioned in close proximity to the spool so that when the motor is on, the winder roller 22 contacts the quick fire coil 10 and thus allows the spool to be rotated by the motor 24 so that the hose is wound back on the spool 10. , the roller 22 - is detached from the rapid fire reel 10. According to a preferred embodiment, when the winding device is at rest, the distance of the roller 22 from the reel 10 is Imm-1m. The motor 24 is arranged to rotate the roller 22, and in the example of Fig. 7 is fixed to the frame 28, and shares the axis of rotation with the roller and rotates the roller therethrough. Also o 35 - any arrangement between the motor and the roller is possible according to the invention to transmit O motor power to the roller 22. S The belt 26 is arranged to start the motor 24. The starting can be © for example by pulling down and the motor 24 can start when it detects traction 9 40 - in the belt or as the roller 22 presses against the coil. In the example of the figure, the belt 26 is attached E to the frame 28, at the opposite end to which the motor is attached. But other arrangements for starting the engine by pulling the belt, for example without a frame, are also possible. 3 N 45 In the example of Fig. 7, the body 28 is divided into two parts in the longitudinal direction, where the motor is attached to the first part N in the figure and the belt to the second part. In the embodiment according to Fig. 3, the attachment point a is fixed to the wall and acts as a support point and a joint so that when the belt is pulled down and the second part of the body moves downwards, the first part of the body rises on the upward roller 22 simultaneously starts, the force transmitted by the motor is transmitted through the rotational movement of the roller 22 to the coil by means of friction. In this case, the coil starts to rotate, whereupon the hose arranged around the coil starts to rewind - back to the coil. Other possibilities for transmitting force to the coil 10 are also possible, for example a gear. In order to prevent the roller from being pressed too hard against the coil, in a preferred embodiment of the invention the transmitted force is limited by a spring 32. The spring can be selected and installed so that, for example, a force corresponding to more than 8 kg is not transmitted to the roller. This ensures that when a higher force is applied to the pull, the retractor cannot break. Figures 5 and 6 illustrate an electric winding device according to the invention in use. Figure 5 illustrates the start of winding where a handle is connected to the belt 26, from which - downwards - the winding is started. When the belt is pressed down enough, the roller will come in contact with the quick fire reel (Figure 6). Since the motor is started when the belt is pressed down, the electric motor, through the rotational movement of the roller, begins to rotate the quick fire reel, and thus the hose begins to rewind onto the quick fire reel.
