Definitions

  • the invention relates to a device for baking a marking into objects, in particular into the fiber jacket of a tennis ball with the aid of at least one symbol made of metal corresponding to the marking, which is attached to a holder and can be heated to the baking temperature by the flame of a heating device directed towards the symbol.
  • a burn-in template as a device of the aforementioned type, which is designed as pliers which grips the ball with a leg shaped like a sector of a sphere and presses it against the template facing the ball on the other leg.
  • the stencil is heated electrically so that it penetrates into the fleece-like fibrous materials in a knife-like manner and burns it down to the inner shell, so that the marking remains visible due to the abrasion that occurs during play (DE-A-2810653).
  • pincer-type devices are usually available in the manufacturing plants, at the sales outlets or in clubs for applying the desired markings, but are generally not available to the individual tennis player when he is about to start playing with a new set of tennis balls.
  • a portable branding iron in which a gas bottle is exchangeably attached to a solid support with a handle attached to the free end.
  • the iron is heated with the help of the gas bottle contents, to which air is supplied through lateral supply holes in the iron, until the front surface of the iron with the letters on it has reached the baking temperature. It is a comparatively heavy device because a support frame is provided.
  • the invention has for its object to provide a device which is extremely simple and handy and can be carried in the pocket of anyone, the operation of the device is simple and easy to carry out.
  • the device is designed as a liquid gas-operated hand lighter with an ignition mechanism that can be actuated from the outside, on the open end face of which is arranged the symbol that projects to the burn-in depth over two opposite housing edges and that the heating device in the form of at least one nozzle in one is provided at a distance from the end face in the housing transverse wall.
  • Hand lighter is to be understood in the usual sense of the word a lighter as it is used for lighting cigarettes or the like.
  • the device according to the invention has the advantage that it is just as simple as a lighter and can be operated. Due to the handiness of the device, the tennis player will always carry it with him with his other utensils, so that he is always ready when he wants to start playing with a new set of tennis balls and considers it necessary to attach the markings to one To avoid confusion with the balls of the neighboring square.
  • the device according to the invention can also be used to mark other objects, for example school bags or the like. be used.
  • edges of the housing are expediently concave to match the shape of a tennis ball.
  • the metal webs can be held tiltably with play on the housing side, so that their surface can align when pressed against an object to form this object by pivoting the webs in the housing-side holding opening.
  • the holding openings can be formed in the opposite housing walls or in wall-parallel housing-fixed webs.
  • the flame or flames which burn from the nozzle or openings provided on the housing transverse wall then heat the symbol or the symbols directly or by heat conduction via the fine-meshed network of metal wire which is provided at least in the vicinity of the symbol.
  • the symbol is sufficiently heated, for example at a temperature of 250 to 300 ° C, the device is pressed against the object to be marked, for example a tennis ball, whereby the heated symbol makes the corresponding mark in the surface of the object, here the fiber material of the Tennis ball burns in, but only to the depth that corresponds to the protrusion of the symbol over the housing edges forming the front side, against which the object, for example the tennis ball, comes to rest.
  • the device shown in FIGS. 1 to 3 is used to burn a mark into the fiber jacket of a tennis ball. It consists of a cuboid housing 1, the side walls 3 of which protrude above a transverse wall 10 and end in edges 9 which delimit a dome-shaped concave front face 2 which is adapted to the spherical shape of a tennis ball.
  • a refillable liquid gas storage device is provided as in the case of a lighter.
  • the liquid gas reservoir is connected via a discharge valve, not shown, to a nozzle 8 in the transverse wall 10, which is directed towards the end face 2.
  • the outlet valve of the nozzle 8 and the ignition mechanism 13 are actuated with the aid of an adjusting button 7 arranged on a housing wall 3.
  • recesses 11 are provided for clamping metal webs 4, on which a symbol 5 in the form of the letter L is held.
  • the metal web 4 has at both ends a shoulder 12, the cross section of which is smaller than the opening area of each recess 11. This web holder enables pivoting or tilting of the symbol 5 attached to the metal web 4 and thereby an alignment of the Symbol 5 with respect to the surface to be marked.
  • the outlet valve of the nozzle 8 is opened and the ignition mechanism 13 is actuated, as a result of which, for example, a spark that ignites the gas is generated piezoelectrically.
  • the symbol 5 is sufficiently heated by the gas flame, which is the case after approx. 5 to 10 s, the tennis ball is pressed against it, whereby the symbol 5 burns the marking into the fiber jacket of the tennis ball, but only to the desired depth, since a further burn-in is prevented by the tennis ball resting on the edges 9.
  • FIGS. 5 to 7 two symbols 5 in the form of the letters D and V are provided, which are adapted to the curvature of the edges 9 in recesses 11 in opposite side walls 3 of the housing 1 above the edges 9 above.
  • Each symbol 5 is assigned a nozzle 8 on the transverse wall 10.
  • Each nozzle 8 has an outlet valve, not shown, which, like the ignition mechanism 13, is actuated by an adjusting button 7 on a housing wall 3 in a manner known per se.
