Golf green trainer

Abstract

A golf green trainer comprises a mainframe chest, an immovable putt plate, and an electronic control chest. The mainframe chest further comprises an angular adjusting device, a ball sweeping device, a ball collecting device, and a ball supplying device such that users can set the angular adjusting device by means of the electronic control chest for adjusting the inclination angle of the golf green plate so as to simulate a real golf green surface. By means of the ball sweeping device, the golf ball which can not be putted into the hole nor to the out-of-bounds but remain on the golf green plate will be swept into the ball collecting device. By means of the ball collecting device, the ball which is putted into the hole and the ball which is swept into the ball collecting device will be collected for replenishing the ball supplying device. By means of the ball supplying device, the golf ball will be supplied to one end of the immovable putt plate for users to putt.

What is claimed is:  
     
         1 . A golf green trainer comprising: 
 a mainframe chest including a golf green plate mounted thereon with a hole disposed at one end for receiving a golf ball and a photoelectric sensor installed at the other end for detecting the golf ball passing through;    an immovable putt plate extended from one end of the mainframe chest for users to putt the golf ball placed thereon; and    an electronic control chest disposed on one side of the mainframe chest;    wherein the mainframe chest further comprises an angular adjusting device, a ball sweeping device, a ball collecting device, and a ball supplying device such that users can set the angular adjusting device by means of the electronic control chest for adjusting the inclination angle of the golf green plate so as to simulate a real golf green surface; by means of the ball sweeping device, the golf ball which can not be putted into the hole nor to the out-of-bounds but remain on the golf green plate will be swept into the ball collecting device; by means of the ball collecting device, the golf ball which is putted into the hole and the golf ball which is swept into the ball collecting device will be collected for replenishing the ball supplying device; by means of the ball supplying device, the golf ball will be supplied to one end of the immovable putt plate for users to putt.    
     
     
         2 . The golf green trainer as claimed in  claim 1 , wherein the angular adjusting device comprises: 
 a rocking lever beneath the golf green plate for supporting and rocking the golf green plate;    pivot axle disposed at the middle of the rocking lever for the rocking lever to pivot thereon;    a joint installed at one end of the rocking lever;    a link connecting the joint at a first end and a cam at a second end;    a cam connected to the shaft of a first motor having a lower point and a higher point for carrying the second end of the link to move between a lower position and a higher position; and    a first motor controlled by a first micro switch which is electrically connected to the electronic control chest such that users can operate the first motor by means of the first micro switch through the electronic control chest to rotate the cam between the lower point and the higher point then drive the link and the rocking lever, and consequently, the golf green plate can be changed with a desired angle.    
     
     
         3 . The golf green trainer as claimed in  claim 1 , wherein the ball sweeping device comprises: 
 a sweeping rod carrier part which carries the sweeping rod to move forward and backward on two parallel slideways, the sweeping rod carrier part furthermore comprises: 
 a first chassis with one set of rollers on a first side and another set of rollers on a second side opposed to the first side for rolling on the two parallel slideways;  
 a sweeping rod installed on the top of the first chassis for sweeping the golf ball; and  
 a touching block mounted beneath one end of the sweeping rod for touching a second micro switch so as to control a second motor; and  
 a power transmission part, the power transmission part furthermore comprises: 
 a second chassis having two parallel slideways and a platform for the sweeping rod carrier part to slide thereon;  
 a driving sprocket installed at one end of the second chassis and connected to the shaft of the second motor;  
 a driven sprocket installed at the other end of the second chassis;  
 an endless chain driven by the driving sprocket and moving around the driving sprocket and the driven sprocket;  
 an idle sprocket provided between the driving sprocket and the driven sprocket for stretching and adjusting the endless chain; and  
 a carrying rod fixed on the endless chain and coupled with the first chassis for carrying the sweeping rod carrier part such that a timer will begin to count time right after a golf ball is putted and passes through the photoelectric sensor, and if the golf ball is not putted into the hole nor to the out-of-bounds within a time period, the second motor will be energized to drive the endless chain and then the sweeping rod carrier part to sweep the golf ball with the sweeping rod.  
 
   
     
     
         4 . The golf green trainer as claimed in  claim 1 , wherein the ball collecting device comprises: 
 a middle groove disposed below the hole, and a third micro switch installed thereon for identifying the golf ball passing through the middle groove into the hole;    an east groove disposed between the immovable putt plate and the east side of the golf green plate, and a forth micro switch installed thereon for identifying the golf ball passing through the east groove to the out-of-bounds;    a west groove disposed between the immovable putt plate and the west side of the golf green plate, and a fifth micro switch installed thereon for identifying the golf ball passing through the west groove to the out-of-bounds;    a north groove disposed between the immovable putt plate and the north side of the golf green plate for guiding the golf ball to the east groove or the west groove;    a south groove disposed on the south side of and below the golf green plate for guiding the golf ball coming from the middle groove and the west groove; and    a turn groove disposed below the golf green plate for guiding the golf ball from the east groove and the south groove to the ball supplying device.    
     
     
         5 . The golf green trainer as claimed in  claim 1 , wherein the ball supplying device comprises: 
 a third motor fixed on the mainframe chest;    a crank with one end connected to the shaft of the third motor and the other end to the ball supplying arm;    a ball supplying arm with one end having a ball holder and the other end pivotally connecting to a supporter fixed on the mainframe chest;    a first spring connecting the ball supplying arm and the supporter;    a ball supplying groove fixed on the mainframe chest for guiding the golf ball from the ball holder to the immovable putt plate so as to supply the golf ball to the user;    a damping plate whose middle point is pivotally connected to the ball feeding hood, a first end is disposed below the ball holder and a second end connects to a second spring mounted on the mainframe chest so as to damp the ball holder falling down;    a ball feeding hood fixed on the mainframe chest for helping the golf ball to enter the ball holder; and    a sixth micro switch installed on the ball supplying groove for determining whether it is necessary or not to supply further a ball.    
     
     
         6 . The golf green trainer as claimed in  claim 1 , wherein an ambient lighting cover is disposed above the mainframe chest and the golf green plate to prevent the photoelectric sensor from being interrupted by persons or moving objects nearby so as to assure the photoelectric sensor can accurately detect the golf ball passing through.  
     
     
         7 . The golf green trainer as claimed in  claim 1 , wherein a pedal is installed beside one end and at the same level of the immovable putt plate for the user stepping thereon while putting a golf ball.  
     
     
         8 . The golf green trainer as claimed in  claim 1 , wherein the photoelectric sensor is employed to count the number of balls passing through, the third micro switch is employed to count the number of balls putted into the hole, and a display device is installed on the electronic control chest for displaying the number of balls passing through and the number of balls putted into the hole.
