Definitions

• This invention relates to a device for recording over ⁇ steps in connection with the exercise of sports in the form of, for example, long jump, hop-step-and jump, jav ⁇ elin throwing and the like.
• a so- -called overstep bank is used for the control of over ⁇ steps.
• Said bank consists of a marking board located in direct connection to the take-off board and provided with a flat, smooth strand of plastelinej model clay or similar easily pliable material.
• the plasteline strand with a total width of about 2 dm, extends at an angle of 30° upward from the edge of the take-off board which is the leading edge in the jump direction and is then in parallel with the upper surface of the take-off board.
• the plasteline strand can be laid on a hard, not removable support or on a removable so- -called 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 dec ⁇ ide 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 hop 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 poss ⁇ ible, 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.
• An overstep ramp according to the present invention is provided in the jumping direct ⁇ ion directly after the take-off board 3.
• the overstep ramp ⁇ *. 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 ⁇ * is 150°, i.e. the portion of the step cushion as well as of the carrier located closest to the take- -off 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 upp ⁇ er tight 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 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 an air gap 11.
• the step cush ⁇ ion 7 is provided on its upper surface with a wear surf ⁇ ace 12 of rubber coated with friction agent, which can form a separate layer rigidly connected to the tight layer 8 or constitute an integrated part of the tight layer 8, in order, especially at rainy weather, to prev ⁇ ent 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 schematic ⁇ ally in the drawing, is located and connected to the air gap 11. Said valve is connected through an airtight line I ⁇ (Fig. 1) to a pressure indicator 17, to which a signal member 18 is coupled which is connected to the mains or a battery. Upon sensing a pressure increase in the step cushion 7, said signal member 18 emits an optic and/or acustic signal.
• the signal member 18 is shown in the form of a signal lamp emitt ⁇ ing an optic signal in the form of red light.
• the sign ⁇ al member 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. It is also possible to provide as an extra signal member a manometer or the like, which rec ⁇ ords the pressure at overstep, and which has a pointer remai ⁇ ingin the position of deflection, and which, thus, at least approximately can indicate the degree of over ⁇ step, i.e. whether the overstep is minute or substant ⁇ ial.
• the pressure increase required for the pressure indic ⁇ ator 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 there ⁇ by is subjected to a load, which presses together the air gap 11 in the step cushion 7, and thereby the air pressure in the air gap 11 increases.
• the increased air pressure in the air gap 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 air gap 11 in the step cushion 7 has a predeterm ⁇ ined pressure.
• a press ⁇ ure gauge (not shown) is located in a suitable place between * the cushion 7 and pressure indicator 17. Said latter preferably can be equipped with such a pressure gauge, and if the air pressure should change during the 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 comprised in the device according to the invention is removable and can abut directly to the edge side 20 of the take- -off ramp which faces toward the jumping pit 2 and in Fig. 2 partially is marked by a dashed line. Said edge side also is the reference line, from which the length of the jump is measured. Said overstep ramp also may be 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.
• Overstep also 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 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.
