Definitions

  • This invention relates to a device for recording overstep of a predetermined reference line by a sportsman which device comprises a step cushion having one side extending parallel to said reference line when positioned for use and including an airfilled and airtight cavity of a definite volume and an upper layer of elastic material enclosing said cavity, which layer, upon being loaded on its upper surface, is flexible to instantaneously reduce the volume of the cavity thereby causing a pressure increase, said cavity being connected to a pressure sensor which, in response to such a pressure increase, causes a signal member to emit an optical and/or acoustic signal.
  • a device of the type described above for recording oversteps in connection with different sports is known from the FR-A-2 299 047.
  • Said device includes a step cushion in the form of a tube of rubber located on the bottom of a recess.
  • Said tube is covered by a step board also located in said recess to act on the tube.
  • the step board acts on the tube to reduce the volume thereof thereby causing a pressure increase being used to cause a signal member to emit a signal.
  • Said known device for recording oversteps is not safe in function due to difficulties of avoiding entrance of sand particles and other undesired particles into the recess containing the tube. If such particles are allowed to enter into the recess and between the surfaces of thereof and the step board, they will reduce the movability of the step board within the recess, making said overstep recording device very insensitive and unusable in practice.
  • an overstep bank is used, said bank consisting of a marking board located in direct connection to a take-off board and provided with a flat, smooth strand of plasteline, model clay or similar easily pliable material.
  • the plasteline strand can be laid on a hard, not removable support or on.a removable plasteline board.
  • the overstep is recorded in the form of a mark in the smoothly formed plasteline surface.
  • the overstep is substantial, there is no problem for the officials to decide that overstep has occurred.
  • the overstep is minute, it can in many cases be very difficult for the officials to decide whether or not overstep has occurred. It is, therefore, necessary at competitions to have several officials for making the decision whether overstep has occurred or not.
  • This known technique of marking and recording oversteps also involves the disadvantage, that the spectators at the same time as the jump is carried out cannot decide whether the jump is okay or not, but must wait for the judgment by the officials.
  • This disadvantage also contributes to the fact that, for example, long jump and hop-step-and jump competitions are not so attractive and engaging for the spectators.
  • the present invention therefore, has the object to provide a device for overstep recording, which does not show the aforesaid disadvantages, but renders it possible, even for the spectators, to safely and directly record whether overstep has occurred or not, and which does not require any restoring work after an overstep, but rather permits a stream of jumps.
  • Fig. 1 is a schematic horizontal view of a long jump grounds equipped with the device according to the invention
  • Fig. 2 is on an enlarged scale a section substantially along the line II-II in Fig. 1.
  • the numeral 1 designates a run path for long jump
  • 2 designates a jumping pit.
  • a take-off board 3 is located in the run path 1, at the intended distance from the jump pit 2.
  • An overstep ramp 4 according to the present invention is provided in the jumping direction directly after the take-off board 3.
  • the overstep ramp 4 comprises a carrier 6 of rigid, i.e. non-resilient or inflexible material, for example wood, which is detachably attached on a rigid support 5 (Fig. 2), and a step cushion 7, which is rigidly connected to the angularly designed upper surface of the carrier.
  • said angle a is 150° ; i.e. the portion of the step cushion as well as of the carrier located closest to the takeoff board 3 extends upward from the take-off board 3 at an angle of 30° in relation to the horizontal plane and then is in parallel with said plane.
  • the step cushion 7 comprises an upper elastic tight layer 8 of rubber or similar elastic material with high airtightness, i.e. a material which is not air-permeable, and a bottom layer 9 of the same material as in the upper layer 8 or of stiff airtight rubber or other comparable material which is not air-permeable.
  • These layers or parts 8, 9, by overall wall portions 10, 10a of the same material as in the tight layer or bottom layer, are designed in one single piece or connected to each other and form between themselves a cavity 11 filled with air.
  • the step cushion 7 is provided on its upper surface with a wear surface 12 of rubber coated with friction agent, which can form a separate layer rigidly connected to the layer 8 or constitute an integrated part of the layer 8, in order, especially at rainy weather, to prevent the jumper from slipping or sliding in some other way against the overstep ramp 4, even at substantial overstep.
  • the step cushion 7 preferably should be located so on its carrier 6, that it rests with its edge 13 remote from the take-off board 3 against a shoulder 14 formed on the carrier 6.
  • the upper surface of said shoulder should be on the same level as the wear surface 12 of the step cushion or on a slightly lower level than the same.
  • a stop valve 15 shown only schematically in the drawing, it located and connected to the cavity 11. Said valve is connected through an airtight line 16 (Fig. 1) to a pressure indicator 17, to which a signal member 1 is coupled which is connected to the mains or a battery.
  • said signal member 18 Upon sensing a pressure increase in the step cushion 7, said signal member 18 emits an optic and/or acoustic signal.
  • the signal member 18 is shown in the form of a signal lamp emitting an optic signal in the form of red light.
  • the signal member of course, can have any other suitable form, provided that the signal emitted thereby for marking overstep can be recorded and be seen and/or heard by the spectators.
  • a manometer or the like which records the pressure at overstep, and which has a pointer remaining in the position of deflection, and which, thus, at least approximately can indicate the degree of overstep, i.e. whether the overstep is minute or substantial.
  • the pressure increase required for the pressure indicator 17 to cause the signal member 18 to emit a signal arises as soon as a jumper contacts with the shoe the step cushion 7.
  • the upper surface of said cushion thereby is subjected to a load, which presses together the cavity 11 in the step cushion 7, and thereby the air pressure in the cavity 11 increases.
  • the increased air pressure in the cavity 11 of the step cushion is sensed by the pressure indicator 17, which, in its turn, causes the signal lamp 18 to light.
  • the lamp by its red light shows directly to the jumper, the officials and the spectators that the jump carried out last is not okay due to overstep.
  • the cavity 11 of the step cushion 7 includes air of a predetermined pressure.
  • a pressure gauge (not shown) is located in a suitable place between the cushion 7 and pressure indicator 17.
  • said indicator can be equipped with such a pressure gauge, and if the air pressure should change during a competition, it can be corrected either by supplying additional air, for example by means of a pump, or by tapping air via the stop valve 15 or by calibrating the pressure indicator.
  • the overstep ramp 4 included in the device according to the invention is removable and is recessed into the take-off board 3 a distance which substantially corresponds to the thickness of the wall portion 10a (Fig. 2) of the step cushion.
  • the edge side 20 of the take-off ramp which faces toward the jumping pit 2 is marked by a dashed line in Fig. 2. Said edge side also is the reference line, from which the length of the jump is measured.
  • overstep is to be understood as false start at competitions with flying start or standing start, where the runners must not pass a reference line, i.e. a start line, before a start signal is given.
  • the overstep ramp according to the invention has been shown to be straight in the drawings, but it may also be arched so as to fit a shot putter and hammer throwing ring.
