Grip with an angle adjustable structure for a golf cart
BACKGROUND OF THE INVENTION 
     A conventional golf cart generally has a grip 1 connected firmly with a vertical rod of a golf cart body 2 by means of a socket-shaped connector 11 so that the grip cannot be adjusted in its angle toward the golf cart body 2 to facilitate to pull it along on the ground, as shown in FIG. 6. 
     SUMMARY OF THE INVENTION 
     This invention has been devised to supply a grip with an angle adjustable structure for a golf cart, having the following structural features. 
     1. The grip can be moved to any angle with a pulling rod as a pivot before tightening the grip by pushing a tightening member, so a golf cart provided with this grip can be pulled to move smoothly on the ground. 
     2. It is provided with a pulling rod to pull two bevel gears in separated condition to engage with each other so as to tighten the grip in any angle in an easy way. 
     3. It is provided with a tightening member to be moved to pull the pulling rod in the horizontal direction so that the grip can be also moved horizontally to force the two bevel gears to engage with each other. 
     4. All its components are made separately as a unit so as to be assembled together easily and quickly.

     DETAILED DESCRIPTION OF THE INVENTION 
     The grip with an angle adjustable structure for a golf cart in the present invention, as shown in FIGS. 1-5, comprises a grip 1, a connecting block 2, a pulling rod 3 and a tightening member 4 as the main components. 
     The T-shaped grip 1 has an elongate inner hole 11 for a hand to insert therein, and a projecting ring 12 at the lower portion. The projecting ring 12 is provided with a flange 121 at the left side, a vertical bevel gear 123 around a recessed hole 124 and a through hole 125 in the center of the bevel gear 123. The bottom face of the recessed hole 124 is in contact with one end of a spring 126. 
     The connecting block 2 has a fitting body 21 bored with a fitting hole 211 to fit with the end of a vertical rod of a golf cart to combine the grip with the golf cart and a connecting ring 22 extending up from a curved surface on the fitting body 21. The connecting ring 22 is also combined with the grip 1, having a bevel gear 231 on the left side of a projecting post 23 inside the connecting ring 22, a recessed hole 232 and a through hole 233, and an annular groove 24 between the projecting post 23 and the outer wall of the ring 22. The recessed hole 232 is for containing the spring 126 having the other end contacting with the bottom of the hole 232. 
     The pulling rod 3 is to be positioned through the through hole 125 in the grip 1 and the through hole 233 in the connecting block 22, having a ring pivot 32 at the left end to be positioned at the opening of the through hole 233 and a thread portion 33 at the right end to be positioned in the recessed hole 122 to screw with a nut 31 so as to hold the pulling rod 3 in its position. 
     The tightening member 4 has a semi-circular portion at the left side so as to be manually moved and an actuating ring 41 at the right side. The actuating ring 41 is provided with an annular groove 411 in the middle for the ring pivot 32 in the pulling rod 3 to fit around and a lengthwise through hole 412 eccentrically provided for a rivet 413 to pass through to insert in a hole 321 in the ring pivot 32 and firmly rivetted. 
     In assembling together this invention, as shown in FIG. 2, the spring 126 is at first to be placed in the recessed hole 124 in the grip 1, then the connecting ring 22 of the fitting body 21 is held to let the projecting post 23 fit in the cavity 122 in the projecting ring 12, the annular groove 24 fit with the flange 121 and the other end of the spring 126 inserted in the recessed hole 232 to reach its bottom. Next, the ring pivot 32 is to be fitted around the annular groove 411 in the actuating ring 41 of the tightending member 4, and the rivet 413 is inserted through the through hole 412 in the ring 41 and also the through hole 321 in the ring pivot 32 and then rivetted firmly. Lastly, the pulling rod 3 is put through the through hole 233 in the ring 22 and also the through hole 125 in the projecting ring 12 of the grip 1 and a nut 31 is screwed with the thread portion 33, finishing assemblage of the grip with an angle adjustable structure for a golf cart. 
     In using this grip, as shown in FIG. 3, it is to be connected with the vertical rod 5 of a golf cart. Under the condition that the tightening member 4 is not tightened, i.e. in the released condition, the bevel gears 123 and 231 are separated from each other by the elasticity of the spring 126, so the grip 1 can move in any angle with the pulling rod 3 as a pivot. If the grip 1 is wanted to be tightened at a certain position or angle, it is moved first to the position wanted, then the tightending member 4 is to be shoved downward by catching the semi-circular portion, as shown by the arrow marked in FIG. 3, to let the actuating ring 41 rotate on the side surface of the ring 22 so that the pulling rod 3 is pulled to the left side, forcing the projecting ring 12 with the grip 1 to move laterally to the left side and thus both the bevel gears 123 and 231 come to engage with each other to keep the grip 1 stopped in the position immovable.
