    MOUNTING METHOD AND BRACKET
    OBJECT OF THE INVENTION The present invention relates to a fastening method and a fastener used for releasably / openable fastening of hatches used in various objects, which hatches are used to cover maintenance, monitoring, measuring, adjusting, closing / opening devices, or to cover structural damage.
    BACKGROUND OF THE INVENTION - Today, hatches are used to cover maintenance, monitoring, measuring, regulating, closing / opening devices. Today, service or operation hatches are most often fixed to their frames by screws, in a building, on a ship, in a machine, in a vehicle or in an opening made in a similar service or operation hatch. The frame and hatch are most commonly made of some known metal. The frame and the hatch can be made of some other material, e.g. wood, plywood, fibreboard or the like, the above-mentioned material is usually fastened with screws to the above-mentioned opening of the building, the hatch is most often fastened to the frame with screws. Service hatch means a hatch after which a device can be exposed, eg a stopcock, a meter or the like. An access door is a door that, when opened, can be used to display a device and then do something, such as turn on the device, adjust the device, and read the meters. Hereinafter, the hatch used for both purposes will only be collectively referred to as the hatch. The hatches can also cover any damage to the structure.
    S N 25 - Current hatches always have a door mounting frame, this frame is expensive to manufacture and in addition the frame increases the total weight of the door, making it expensive to transport and store. U.S. Pat. OF
    OBJECT OF THE INVENTION It is an object that a door mounting frame is not required for attaching the door. The door is attached by magnetic attraction.
    The above drawbacks can be eliminated and the above-mentioned objects are achieved by a fastening method according to the invention, which method is characterized by what is defined in the characterizing part of claim 1 and preferred embodiments of the method are the subject of claims 2 to 3. The fastener is characterized by what is defined in the characterizing part of claim 4, and preferred embodiments of the fastener are the subject of claims 5-15. The main advantages of the invention are that the door fastened with the fastener according to the invention does not need a door fastening frame, since the fasteners are separate fasteners, whereby the expensive manufacturing costs of the door frame are eliminated. The invented fastener can be fastened to the corner or straight part of the opening (fastening opening) of the object to be covered by the hatch. The invented bracket is light to carry and does not take up much storage space. The invented bracket is also very quick to install, the bracket is based on magnetic attraction. The invented bracket is equipped with a detachable and attachable movable - flexible bracket, whereby the bracket can be attached to objects of very different thickness / strength, as a result of which the same bracket can be used very widely for hatches used for different purposes or vice versa as a result, the storage costs of the hatches are substantially reduced. It is clear that by using the invented bracket - great cost savings are achieved in the use and installation of the hatches.
    GENERAL INFORMATION ABOUT MAGNETIC FORCE In magnetic phenomena, a piece acts on another piece by tensile or exhaust force. The best-known magnetic phenomenon is the ability of permanent magnets N 25 associated with ferromagnetism - to attract nearby iron objects. Strongly magnetic bodies are called 2 magnets. Such can be made of ferromagnetic materials such as iron, nickel and cobalt and mixtures thereof. The magnet is a very old invention. According to the information provided by Aris- E totle, magnetism was first studied in more detail by Thales, who lived around 625-545 BC. However, at about the same time, Sushruta was also the first in India to use magnets for surgical purposes. The word magnet (Lithos in Greek) is derived from the city of ancient Magnesia in Asia Minor, in the vicinity of which a magnetic ore, magnetite, was found. (Wikipedia magnetism.)
