L. G. SIMJIAN GOLF TRAINER Filed Sept. 16, 1955 TARGET SENSING MEANS TRANSLATING & COMPUTING MEAN$ LUTHER s, SIMJIAN INVEN'I'OR ATTORNEY United States Patent 'Reflectone Corporation, Stamford, Conn., a corporation of Connecticut Application September 16, 1955, Serial No. 534,854
7 Claims. (Cl. 273-185) This invention relates to a game apparatus which permits a player to propel a missile within the restricted space of an enclosure and then view the results of his efforts on a miniature scale, showing the approximate path of the missile if the play had been made out of doors. The invention has particular reference to an apparatus which will show the results of a player throwing or batting a ball on a baseball diamond or of a golfer driving a golf ball on a golf course.
There have been several structures devised which will permit a golf or baseball player to practice indoors but none of these structures shows the player the approximate trajectory of the propelled missile in three dimensional space. The present invention employs a free ball within the restricted space of a room or otherwise restricted enclosure, using a target to sense thedirection of the propelled missile; A miniature game field is provided which simulates an outdoor playing field and the path of the ball is indicated in three dimensions by a-plurality of motors which project a ball on the miniature course or field in the same direction but with a much lower velocity as the ball would have taken if played out of doors. One prior art device has endeavored to show the approximate trajectory of a propelled missile by the movements of a projected spot of light on a viewing screen. Such an arrangement has obvious disadvantages since the movement of the spot occurs in two dimensions only, and does not give the player a true picture of the movement of the missile.
One of the objects of this invention is to provide an improved game apparatus which avoids one or more of the disadvantages and limitations of prior art arrangements.
Another object of the invention is to provide a game apparatus which may be used indoors in a restricted space and which has many of the advantages of a game out of doors.
Another object of the invention is to provide a three dimensional visual result of a player's efforts.
Another object of the invention is to instruct a player by showing some of the faults and errors made by a player while projecting a missile toward an objective.
Another object of the invention is to provide a game apparatus which may be used in competitive play by two or more players.
Another object of the invention is to simplify and reduce the cost of indoor games while at the same time making them more accurate in showing the results that would have happened if a missile had been projected out of doors.
For a better understanding of the present invention, together with other and further objects thereof, reference is made to the following description taken in connection with the accompanying drawings.
Fig. 1 is a schematic representation of the components of the game apparatus showing a target sensing means, a translating means, and a control means which moves a 2,894,754 Patented July 14, 19 59 of a missile in three dimensional space.
Referring now to Fig. 1, a missile 10 is indicated on a supporting means in a position to be driven toward a target sensing means 11. The missile 10 may be a golf ball, abase ball, or football. The general direction of the path of the missile is indicated by a dotted line 12. The target sensing means 11 is connected to a translating and computing means 13 which determines the approximate direction, height, and speed of the missile and operates a control means 14 to position a miniature missile 15 held by a string 16 to simulate the motion of the missile on a small scale.
In order to move the missile 15 in three dimensional space in accordance with the approximate trajectory of the struck missile, three motors 17, 18, and 20, shown in Fig. 2 are employed. These motors are mounted on a movable frame which moves on rails 21 and 22, the motion along the rails being provided by motor 20 which is coupled to wheels 23 and 24 by means of a gear and pinion arrangement 25. Motion to the right or left of a desired direction is controlled by motor 17 which moves a carriage base 26 at right angles to rails 21 and 22 by means of a gear coupling 27 between motor 17 and Wheels 28. The vertical motion of missile 15 is controlled by motor 18 which moves a drum 30 on which is wound a portion of string 16. The operation of such an apparatus may be briefly described as follows; The missile is propelled by the player against the target sensing means 11 and when the missile leaves the starting position, switch contact 10A is actuated which is connected to translating and computing means 13. The approximate path of the missile in free flight is determined by the missile impact position on target sensing means 11 and the velocity of the missile is determined by the elapsed time interval between actuation of contact 10A and the impact on target sensing means 11. .Information furnished by the target sensing means and contact 10A is applied to the translating and computing means 13 and then the control means 14 causes the missile 15 to be raised and lowered above a miniature playing field 31, showing the player the approximate path of' the missile if his drive had been made out of doors.
One form of target sensing means has been described in detail in application No. 474,812, filed December 13, 1954, by Mr. Luther G. Simjian, now US. Patent 2,784,- 001, issued March 5, 1957. This disclosurelshows a target sensing means which employs crossed conducting wires in connection with a chargeable capacitor and a series of three motors connected to a computing system. This application also discloses a motor normalizing circuit which could be used in the apparatus described herein.
The application describes in detail the generation of electrical signals which are proportional to the trajectory of the missile in unrestricted space along the two nor mal axes in the horizontal plane and along the vertical axis as sensed by the impact position of the missile on the target and as a function of the missiles time of flight between the support means and the target which in turn, is a measure of the missiles velocity and hence, of the missiles distance in unrestricted space.
It will be evident from the above description that a game apparatus has been disclosed wherein a free missile such as a golf ball, a base ball, or foot ball, may be impelled against a target sensing means and the resulting trajectory observed on a miniature playing field.
While there has been described and illustrated a specific embodiment of a game apparatus, it will be obvious that various changes and modifications can be made therein without departing from the field of the invention which should be limited only by the scope of the appended claims.
