## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a golf bag structure, and more particularly to a golf bag structure with two leg assemblies that can stand stably on the ground.
2. Description of Related Art
Golf bags are used to hold golf clubs. A conventional golf bag is cylindrical and has a flat bottom so that the golf bag can stand upright on the ground. However, grassy surfaces of most golf courses are not flat. A golf bag standing on the grass may easily fall over.
A conventional golf bag, called stand bag, comprises a bag body, two legs, a supporting foot and two activating flexible rods. The bag body has an open top, a bottom and a sidewall. The legs are attached pivotally to the sidewall of the bag body close to the top, and each leg has a proximal end. The supporting foot is mounted pivotally on the bottom of the bag body and has a bottom that contacts the ground when the golf bag stands on the ground. The activating rods are connected pivotally to the supporting foot, and each activating rod has a distal end. The distal ends of the activating rods are pivotally attached respectively to the legs near the proximal ends of the legs. Inclining the bag body relative to the supporting foot causes the activating rods to pivot the legs away from the bag body so that the golf bag can stand obliquely and stably on the ground.
However, the activating rods are made with metal and therefore are heavy, are exposed and are damaged or broken easily in the course of normal use.
To overcome the shortcomings, the present invention provides a golf bag structure with two leg assemblies to mitigate or obviate the aforementioned problems.
SUMMARY OF THE INVENTION
The main objective of the invention is to provide a golf bag structure with two leg assemblies that is lightweight, has a simple operation and can stand stably anywhere on a golf course.
A golf bag structure in accordance with the present invention and an outer covering form a golf bag, and the golf bag structure comprises a base, a post, a top frame, two leg assemblies and a cord.
The base has a pivot bracket and a cord guide with a through hole. The pivot bracket is attached pivotally to the base.
The post is attached to the pivot bracket.
The top frame is attached to the post and has a divider and a passage defined through the divider.
The leg assemblies are attached to the top frame, and each leg assembly has a pivot mount and a leg. The pivot mount is attached pivotally to the top frame. The leg is attached to the pivot mount.
The cord extends through the through hole in the cord guide and the passage in the top frame and is connected to the base and the pivot mounts of the leg assemblies.
Other objectives, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

The mounting hole (131) is defined in the distal end of the pivot bracket (13). The cord guide (133) is formed on the pivot bracket (13) and has a through hole (135) defined through the cord guide (133).
The post (20) is attached to and extends up from the pivot bracket (13) and has a top end, a bottom end and a curved handle (21). The bottom end of the post (20) is mounted in the mounting hole (131) in the pivot bracket (13). The curved handle (21) is a section of the post (20) near the top end.
With further reference to FIGS. 2 and 5, the top frame (30) is mounted on the top end of the post (20) and has a central opening, an outer surface, an inner surface and a divider (31). The central opening has a front and a rear. The divider (31) is attached to the inner surface of the top frame (30) across the central opening, divides the central opening into at least two smaller openings, may be Y-shaped, has a longitudinal divider (311), a cord passage (312) and multiple transverse dividers (313). The longitudinal divider (311) is formed from the front of the central opening to the rear of the central opening, divides the central opening of the top frame (30) to two sub openings and may be Y-shaped. The cord passage (312) is formed longitudinally through the longitudinal divider (311) and has a rear opening (3121) and two front openings (3122) opposite to the rear opening (3121). The rear opening (3121) is close to the post (20). The front openings (3122) are opposite to the rear opening (3121). The transverse dividers (313) are formed between the longitudinal divider (311) and the inner surface of the top frame (30) to further divide the sub openings to smaller openings.
With further reference to FIG. 6, the leg assemblies (40) are attached to the top frame (30) and correspond respectively to the front openings (3122). Each leg assembly (40) has a bracket assembly, a pivot mount (45), a torsion spring (44), a cord cover (46) and a leg (47).
The bracket assembly is attached to the top frame (30) and may have an inside bracket (41), an outside bracket (42) and a pivot pin (43). The inside bracket (41) is attached to and protrudes out from the outer surface of the top frame (30), may comprise a body and a cup (412) and has a pivot hole (411) defined in the inside bracket (41). The body is formed on the outer surface of the top frame (30). The cup (412) is mounted to the body to form the inside bracket (41). The outside bracket (42) is attached to and protrudes out from the outer surface of the top frame (30) parallel to the inside bracket (41), may comprise a body and a cup (422) and has a mounting slot (421). The body is formed on outer surface of the top frame (30). The cup (422) is mounted on the body to form the outside bracket (422) The mounting slot (421) is defined through the outside bracket (42) and is aligned with the pivot hole (411) in the inside bracket (41). The pivot pin (43) is mounted between the inside bracket (41) and the outside bracket (42) and has an outer end, an inner end, a mounting protrusion (431) and a spring hole (432). The mounting protrusion (431) is formed coaxially on and protrudes longitudinally from the outer end of the pivot pin (43) and is mounted in the mounting slot (421) in the outside bracket (42) to fasten the pivot pin (43) to the outside bracket (42). The spring hole (432) is defined in the inner end of the pivot pin (43).
The pivot mount (45) is attached pivotally to the bracket assembly and may be mounted pivotally on the pivot pin (43) between the inside bracket (41) and the outside bracket (42) of the corresponding bracket assembly and has two sides, a protruding pivot pin (451), a mounting hole (452) and a cord mount (453). The protruding pivot pin (451) is formed on one side of the pivot mount (45) and is mounted rotatably in the pivot hole (411) in the inside bracket (41) of the corresponding bracket assembly. The mounting hole (452) is defined coaxially with the protruding pivot pin (451) in the other side, rotatably holds the pivot pin (43) of the corresponding bracket assembly so the pivot mount (45) pivots between the inside bracket (41) and the outside bracket (42). The cord mount (453) is formed on the pivot mount (45) and has a part-circular groove (454) defined in the cord mount (453) and aligning with the corresponding front opening (3122) of the cord passage (312) in the top frame (30).
The torsion spring (44) is mounted in the spring hole (432) in the pivot pin (43), biases the pivot mount (45) to locate alongside the outer surface of the top frame (30) and has two ends securely mounted to the pivot pin (43) and the pivot mount (45). The torsion spring (44) keeps pivot mount (45) from pivoting inadvertently when no external force is applied to the pivot mount (45). Assembly of the inside bracket (41), outside bracket (42), pivot pin (43), pivot mount (45) and torsion spring (44) requires no tools.
The cord cover (46) covers the cord mount (453) and has a tube and a shell. The tube is attached coaxially to the corresponding front opening (3122) of the cord passage (312) in the top frame (30) and has a cord hole (461) defined through the tube and communicating with the front openings (3122) and the part-circular groove (454). The shell is formed on the tube and covers the cord mount (453) having the part-circular groove (454).
The leg (47) is attached to the pivot mount (45).
The cord (50) may be a fiber cord or a metal cable, is lightweight, may be Y-shaped, extends through the through hole (135) in the cord guide (133) and the cord passage (312) in the divider (31) of the top frame (30) and is connected to the inner surface of the sidewall (11) on the base (10) and pivot mounts (45) of the leg assemblies (40). The cord (50) has a bottom end and two top ends. The bottom end is attached to the inner surface of the sidewall (11). The top ends are attached respectively to and pivot the pivot mounts (45), may extend respectively through the front openings of the cord passage (312) and the cord holes (461) in the tubes of the cord covers (46) and may be mounted respectively in the part-circular grooves (454) in the cord mounts (453) on the pivot mounts (45).
An operation to stand the golf bag is simple and has only one step, which is inclining the golf bag on the ground. Inclining the golf bag pivots the post (20) down relative to the base (10). The inclined post (20) causes the cord (50) to pull and pivot the pivot mounts (45) so that the legs (47) on the pivot mounts (45) rotate out and contact the ground to securely stand the golf bag.
The golf bag with the leg assemblies (40) keeps articles such as golf clubs in the golf bag from spilling out. Furthermore, the lightweight cord (50) concealed in the cord passage (312) and the tubes and covered by the shells of the cord covers (46) makes the golf bag compact, light and hardly break. Moreover, one-step operation of standing the golf bag is simple, convenient, effort-saving and time-saving.
Even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only. Changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
