Grip structure with weight and golf club

Abstract

[Subject] The objective is to provide a golf club where a separation of a weight for swingweight adjustment can be certainly prevented and the weight can be easily detached/attached and replaced; concurrently, the center of gravity is slanted toward the shaft side, and the center of gravity position can be stabilized. [Resolution Means] A golf club 10 has a grip part 16 and a weight part 18. A threaded shaft 26 is established at the grip part 16 side, and a female screw part 22 is established in the weight part 18. In the gold club 10, the grip part 16 and the weight part 18 can be integrated in the state where a spring washer 30 is interposed, by screwing a threaded shaft 26 with a female screw part 22 under a condition where the spring washer 30 is mounted to the threaded shaft 26.

1 . A grip structure with a weight, comprising:
 a grip part, and   a weight part equipped with a weight for swingweight adjustment to be detachably/attachably mountable to a tip of the grip part, wherein   the center of gravity of the weight part is substantially positioned on the shaft center of the grip part.   
     
     
         2 . The grip structure with a weight according to  claim 1 , wherein
 a threaded shaft is established at either side of the grip part or the weight part;   a female screw part is established at the other side of the grip part or the weight part where the threaded shaft is not established;   a spring washer is mounted to the threaded shaft; and   the grip part and the weight part can be integrated in the state where the spring washer is interposed, by screwing the threaded shaft with a male screw part.   
     
     
         3 . The grip structure with a weight according to  claim 1 , wherein
 a convex joining part is established on either one or both of end surfaces of the grip part or/and the weight part;   a concave joining part that can form a joint structure by fitting into the convex joining part, is established on either one or both of the end surfaces of the grip part or/and the weight part; and   the grip part and the weight part are integrable by forming the joint structures comprising a combination of the convex joining part and the concave joining part at a plurality of sections.   
     
     
         4 . The grip structure with a weight according to  claim 1 , wherein
 the grip part has a cylindrical grip body and a weight connection part;   the weight connection part is placed at the end of the grip part, and is equipped with a slot and is elastically deformable;   the weight part is equipped with a shaft-like insertion part to be insertable into the slot, and the insertion part and the weight are detachably/attachably integrated or integrated as incapable of detachment/attachment;   the insertion part has a diameter-enlarging part whose external diameter expands to the size more than the opening size of the slot gradually, and an engagement part that is positioned at the weight side with regard to the diameter-enlarging part, and that is engageable with the slot, and a step difference is formed between the diameter-enlarging part and the engagement part; and   the grip part and the weight part are integrable by inserting the insertion part into the slot and engaging the engagement part with the slot.   
     
     
         5 . The grip structure with a weight according to  claim 4 , wherein
 the grip body is elastically deformable; and   the weight connection part is harder than the grip body.   
     
     
         6 . A golf club equipped with the grip structure with a weight according to  claim 1 . 
     
     
         7 . The grip structure with a weight according to  claim 2 , wherein
 the grip part has a cylindrical grip body and a weight connection part;   the weight connection part is placed at the end of the grip part, and is equipped with a slot and is elastically deformable;   the weight part is equipped with a shaft-like insertion part to be insertable into the slot, and the insertion part and the weight are detachably/attachably integrated or integrated as incapable of detachment/attachment;   the insertion part has a diameter-enlarging part whose external diameter expands to the size more than the opening size of the slot gradually, and an engagement part that is positioned at the weight side with regard to the diameter-enlarging part, and that is engageable with the slot, and a step difference is formed between the diameter-enlarging part and the engagement part; and   the grip part and the weight part are integrable by inserting the insertion part into the slot and engaging the engagement part with the slot.   
     
     
         8 . The grip structure with a weight according to  claim 3 , wherein
 the grip part has a cylindrical grip body and a weight connection part;   the weight connection part is placed at the end of the grip part, and is equipped with a slot and is elastically deformable;   the weight part is equipped with a shaft-like insertion part to be insertable into the slot, and the insertion part and the weight are detachably/attachably integrated or integrated as incapable of detachment/attachment;   the insertion part has a diameter-enlarging part whose external diameter expands to the size more than the opening size of the slot gradually, and an engagement part that is positioned at the weight side with regard to the diameter-enlarging part, and that is engageable with the slot, and a step difference is formed between the diameter-enlarging part and the engagement part; and   the grip part and the weight part are integrable by inserting the insertion part into the slot and engaging the engagement part with the slot.
