Tripod with improved telescopic extension

A tripod including:

• a base;
• first leg members rotatably attached to said base;
• second leg members respectively inserted in said first leg members so that the distance by which each second leg member projects from the associated first leg member can be adjusted, each second leg member having penetration holes formed near the top of the second leg member;
• third leg members respectively inserted in said second leg members so that the distance by which each third leg member projects from the associated second leg member can be adjusted;
• receiving members respectively fixed in the bottoms of said first leg base members;
• and
• catching members disposed on the outer circumferential surface of the upper end portion of each second leg member, each catching member having:
• an acting base portion adapted to catch the corresponding receiving member when the second leg member is projected from the associated first leg member to the fullest extent, and
• a securing protrusion which is formed on the inner surface of the acting base portion and fitted in the corresponding penetration hole so as to protrude from the inner surface of the acting base by a distance such that there is no possibility of the securing protrusion abutting against the top of the third leg member that is inserted in the second leg member.

A tripod including:

• a base;
• first leg members rotatably attached to said base, each first leg member having a brake insertion hole formed near the bottom thereof;
• second leg members respectively inserted in said first leg members so that the distance by which each second leg member projects from the associated first leg member can be adjusted;
• receiving members respectively fixed in the bottoms of said first leg base members;
• catching members fixed on the outer circumferential surface of the upper end portion of each second leg member and adapted to catch the corresponding receiving member when the second leg member is projected from the associated first leg member to the fullest extent;
• operation lever supporting members respectively fixed on the outer circumferential faces of the lower end portions of said first leg members;
• operation levers respectively supported by said operation lever supporting members;
• and
• brakes respectively inserted in said brake insertion holes so that by operating the associated operation lever in the state where its second leg member projects from the first leg member to the fullest extent, each brake is pushed against a portion of the outer surface of the second leg member which is located above the bottom of the catching members of the second leg member, thereby securing the second leg member to the associated first leg member.
