Adjustable frame structure for golf bag
An adjustable frame structure for golf bag includes a body frame unit including a bottom frame having a plurality of upwardly extending and equiangularly spaced plug holes and a top frame having a plurality of downwardly extending and equiangularly spaced plug holes, the plug holes of the bottom frame and the top frame each defining an axially extending base passageway and a plurality of shadow axial passageways and deep axial passageways alternatively arranged around and disposed in communication with the axially extending base passageway, and connection rods selectively insertable with respective opposite ends thereof into the axially extending base passageway and the shadow axial passageways or deep axial passageways of the plug holes to connect the bottom frame and top frame of the body frame unit at one of a series of different heights.
1. Field of the Invention
The present invention relates to golf bags and more particularly, to a frame structure for golf bag, which allows adjustment of the height of the body frame unit thereof for making a golf bag at one of a series of different heights by: selectively inserting the ends of connection rods into shadow axial passageways or deep axial passageways of plug holes in the bottom frame and top frame of the body frame unit.
2. Description of the Related Art
A golf bag generally comprises a body frame unit and a flexible covering surrounding the body frame unit. The body frame unit comprises a bottom frame, a top frame, and a plurality of connection rods connected between the bottom frame and the top frame. After connection of the connection rods between the bottom frame and the top frame, the height of the body frame unit is fixed and not adjustable. If the length of the flexible covering is shorter than the height of the assembled body frame unit, the connection rods must be detached from the bottom frame and the top frame and properly cut and then connected to the bottom frame and the top frame to join them together. If the length of the flexible cover is longer than the height of the assembled body frame unit, the connection rods must be detached from the bottom frame and the top frame, and relatively longer connection rods must be used to substitute for the original connection rods and then connected to the bottom frame and the top frame to join bottom frame and the top frame together. This adjustment method is complicated, wasting much time and labor.
SUMMARY OF THE INVENTIONThe present invention has been accomplished under the circumstances in view. It is therefore the main object of the present invention to provide an adjustable frame structure for golf bag, which allows adjustment of the height of the body frame unit thereof for making a golf bag at one of a series of different heights.
To achieve this and other objects of the present invention, an adjustable frame structure for golf bag in accordance with the present invention comprises a body frame unit and a plurality of connection rods. The body frame unit comprises a bottom frame and a top frame. The bottom frame has a plurality of upwardly extending and equiangularly spaced plug holes. The top frame has a plurality of downwardly extending and equiangularly spaced plug holes. The plug holes of the bottom frame and top frame of the body frame unit each define an axially extending base passageway, and a plurality of shadow axial passageways and deep axial passageways alternatively arranged around and disposed in communication with the axially extending base passageway. The connection rods are selectively insertable with respective opposite ends thereof into the axially extending base passageway and the shadow axial passageways or deep axial passageways of the plug holes of the bottom frame and top frame of the body frame unit to connect the bottom frame and the top frame at one of a series of different heights.
Referring to
The body frame unit 1 comprises a bottom frame 11 and a top frame 12. The bottom frame 11 comprises a plurality of upwardly extending and equiangularly spaced plug holes 2. The top frame 12 comprises a plurality of downwardly extending and equiangularly spaced plug holes 3 corresponding to the plug holes 2 of the bottom frame 11. The plug holes 2;3 each define an axially extending base passageway 23;33, a plurality of shadow axial passageways 21;31 and deep axial passageways 22;32 alternatively arranged around and disposed in communication with the axially extending base passageway 23;33, a plurality of first stop edges 211;311 respectively disposed at an inner side of each of the shadow axial passageways 21;31, a second stop edge 221;321 disposed at an inner side of the axially extending base passageway 23;33 and deep axial passageways 22;32. In this embodiment, the combined cross section of the axially extending base passageway 23;33 and the deep axial passageways 22;32 has a triangular shape. The depth of the shadow axial passageways 21;31 is shorter than the depth of the deep axial passageways 22;32.
Each connection rod 4 defines a plurality of peripheral portions 41 and corner portions 42. The number of the corner portions 42 is equal to the number of the shadow axial passageways 21;31. In this embodiment, the connection rods 4 have a triangular cross section that is same as the combined cross section of the axially extending base passageway 23;33 and the deep axial passageways 22;32.
