Abstract

An automatic golf ball teeing up device has an upper plate formed with a ball passing opening. A ball receiving box is positioned just below the ball passing opening. Golf balls are fed into the ball receiving box one after another. A ball push-up mechanism is employed, which includes a ball push-up member movable in parallel with a major surface of the upper plate into the box to push up the ball in the box to a given upper position, and a tee member movable with the ball push-up member and puts thereon the ball when coming into the box just below the ball-passing opening. A lift mechanism is further employed for lifting up the tee member together with the ball to a predetermined height through the ball-passing opening when the action for putting the ball onto the tee member is completed in the box. A drive mechanism is employed for actuating the ball push-up mechanism and the lift mechanism in order.

first means for feeding golf balls into the ball receiving box one after another;

a ball push-up member movable in parallel with a major surface of said upper plate for picking up the ball in the box and pushing up the ball to a given upper position in said box;

a tee member, which moves with said ball push-up member, for supporting the ball once said ball push-up member pushes the ball to said given upper position and positions said tee member below said ball-passing opening;

a lift mechanism for lifting up said tee member together with the ball through said ball-passing opening to a predetermined height once the ball is placed onto the tee member

a drive mechanism including a moving plate and a single drive means for moving said moving plate in a given direction for successively actuating said ball push-up member, said tee member, and then said lift mechanism; and

second means for lowering the lift mechanism to lower said tee member to the interior of said box when the ball is not supported on said tee member.

6. An automatic golf ball teeing up device as claimed in claim 5, wherein said ball push-up member is formed with an inclined upper surface extending from a pointed leading end of the ball push-up member to a highest trailing end of the same, said pointed leading end being directed to a lower portion of the ball in the box.

7. An automatic golf ball teeing up device as claimed in claim 6, wherein said tee member is connected adjacent to the highest trailing end of said ball push-up member.

8. An automatic golf ball teeing up device as claimed in claim 5, wherein said lift mechanism comprises:

an outer cylinder having a vertically extending first slot;

an inner cylinder slidably received in said outer cylinder, said inner cylinder having a vertically extending second slot, which mates with said first slot;

a piston slidably received in said inner cylinder, said piston supporting thereon said tee member; and

a pin connected to said piston to move therewith and extending to the outside of said outer cylinder through said second and first slots;
