As shown in the drawing, the golf bag 100 having improved mobility according to the present invention includes: a bag body 10 in which a plurality of golf clubs are accommodated; A base bracket 20 fixed to a back surface of the bag body 10; A pair of fixing rods 31 fixed to the back surface or the base bracket 20 of the bag body 10 as extended or immersed by the user, a pair of extensions A multifunction handle 30 having a rod 32, a handle 33 provided on the upper end of the extension rod 32, a pair of wires 35 connected to the extension rod 32 or the handle 33; A pair of guide bar bodies (40) supported on the base bracket (20) in a state where they are opposed to each other on the back surface of the bag body (10) and having rack gear exposure grooves (41) formed on their respective opposing surfaces; And a pair of rack gears 51 that are exposed to the respective rack gear exposing grooves 41 at the side portions and which support the wheels T for movement at the ends A rod support 50 of a rod; A pair of driven gears 60 rotatably mounted on the base bracket 20 and engaged with the rack gears 51 exposed to the respective rack gear exposure grooves 41; A drive gear assembly (70) interlocked with a wire (35) projecting and retreating downward of the fixed bar (31) as the multi - step handle (30) is extended or immersed to forwardly or reversely rotate the driven gear (60); The rod support 50 is interlocked with the rod support 50 and is fixed to the guide bar body 40 and performs a braking operation so that the rod support 50 is fixed at a specific position of the guide bar body 40, And a brake (80) for releasing the braking operation so as to be immersed in the body (40).

The bag body 10 has a tubular shape with an open top and a closed bottom and houses a number of golf clubs such as various kinds of woods, irons, T-shaped, elongated, and semi-circular putters. The bag body 10 is wrapped with a cloth made of cloth or leather.

The base bracket 20 is provided with a guide bar body 40, a driven gear 60, and a drive gear assembly 70, which will be described later. At this time, the base bracket 20 should be in close contact with the bag body 10, and the surface facing the bag body 10 should correspond to the shape of the bag body 10. For example, when a curved surface is formed on the back surface of the bag body 10, the corresponding surface of the base bracket 20 has a concave shape. When the back surface of the bag body 10 is flat, Becomes a plane.

A rubber pad (not shown) may be interposed between the base bracket 20 and the bag body 10. In this case, frictional force is generated between the base bracket 20 and the bag body 10, so that the base bracket 20 can be more firmly fixed to the bag body 10.

The multi-stage handle 30 is composed of a stationary rod 31, an extension rod 32, a handle 33 and a wire 35. At this time, the fixing rod 31 is fixed to the bag body 10 or the base bracket 20, which is illustrated in the present embodiment as being fixed to the base bracket 20 for easy explanation. These fixing rods 31 are fixed by the fixing rod brackets 31a and 31b fixed on the upper side and the lower side of the base bracket 20, respectively.

An upper position fixing hole 31c and a lower position fixing hole 31d are formed on the upper and lower sides of the fixing rod 31, respectively.

The extension rod 32 is provided with a position fixing protrusion 32a which is selectively inserted into the upper or lower position fixing holes 31c and 31d and the position fixing protrusion 32a is engaged with the operation button 33a so as to be immersed in the extension rod 32 or protruded. Therefore, when the position fixing protrusion 32a is caught in the upper position fixing hole 31c, the extending rod 32 keeps protruding from the fixing rod 31, and when it is caught in the lower position fixing hole 31d, The rod (32) remains immersed in the fixed rod (31).

Since the above-mentioned multi-stage handle 30 is commonly used in the art, further detailed description will be omitted.

One side of the wire 35 is connected to the extension rod 32 or the handle 33 and the other side is wound on the pulley 72 of the drive gear assembly 70 to be described later.

Fig. 6 is a perspective view for explaining the bar inclination bracket and the gear inclination bracket formed on the base bracket in Fig. 2, Fig. 7a is a view for explaining the bar inclination bracket of Fig. 6 extending downward with respect to the center line C And FIG. 7B is a view for explaining that the inclination angle of the inclined surfaces of the gear inclination bracket and the bar inclination bracket of FIG. 6 is the same.

As shown in FIGS. 6 and 7A, the base bracket 20 is provided with a bar tilting bracket 21 which is disposed to extend downward with respect to the center line C as a reference. The bar inclined bracket 21 supports the pair of guide bar bodies 40, which will be described later, while being fixedly extended in a downward direction. This is to widen the interval of a pair of wheels T supported by the rod support 50 when the rod support 50 protrudes from the guide bar body 40 supported by the bar inclined bracket 21 .

At this time, as shown in FIG. 6 and FIG. 7B, the bar inclined bracket 21 is formed with an inclined surface that becomes higher toward the bottom than the base bracket 20. This is because between the lower side of the guide bar body 40 supported by the bar inclined bracket 21 and the lower side of the bag body 10 supported by the rod support base 50 when the rod support base 50 is protruded) So that the interval between the first and second electrodes is gradually widened.

That is, the base bracket 20 includes a bar inclined bracket 21 which is disposed so as to extend downward with respect to the center line C and which has an inclined surface that increases toward the lower side. When the guide bar body 40 to be described later is fixed to each of the pair of bar tilting brackets 21, the gap between the wheels T of the rod support 50 projecting from the guide bar body 40 gradually widens And the gap between the wheel T and the bag body 10 is gradually widened. Accordingly, when the wheel T is completely protruded, the bag body 10 and the pair of wheels T form a wide triangle so that they can not stand up or fall down when they are moved.

On the lower bracket 21 of the base bracket 20 is provided a gear inclined bracket 22 on which a driven gear 60 and a drive gear assembly 70 to be described later are rotatably mounted. The direction of the virtual line a extending from the inclined surface of the bar inclined bracket 21 is the same as the direction of the virtual line b extending from the inclined surface of the gear inclined bracket 22 as shown in Fig. This is to ensure that the driven gear 60 to be described later is correctly engaged with the rack gear 51 of the rod support 50.

FIG. 8 is a view for explaining the mutual coupling relationship between the guide bar body, the rod support, the driven gear and the drive gear assembly in the golf bag of FIG. 2, and FIG. 9 is a cross-sectional view taken along the line IX- And Fig. 10 is a view for explaining that the spring employed in the drive gear assembly of Fig. 9 is a spring.

The guide bar body 40 is disposed on the rear side of the bag body 10 so as to extend downward with respect to the center line C and away from the back surface of the bag body 10 toward the downward direction. To this end, the guide bar body 40 is fixed to the bar inclined bracket 21 of the base bracket 20 fixed to the bag body 10, as shown in Fig.

In the pair of guide bar bodies 40, rack gear exposure grooves 41 are formed on the opposite surfaces of the guide bar body 40, in which the rack gears 51 of the rod supports are exposed.

The rod support 50 is slidably coupled to the guide bar body 40 in a downwardly protruding manner. A rack gear 51 is provided on the side of the rod support 50. The rack gear 51 may be separately manufactured and coupled to the rod support 50, It is possible. The rack gear 51 is exposed through the rack gear exposing groove 41 of the guide bar body and engaged with the driven gear 60, which will be described later.

At the end of the rod support 50, a wheel T for movement is supported. The wheel T preferably has a urethane wheel, and a bracket for supporting the rotation axis of the wheel T is separately manufactured and coupled to the lower end of the rod support 50.

The driven gear 60 is meshed with the rack gear 51 which is rotatably mounted on the base bracket 20 and precisely the gear tilting bracket 22 and exposed to the rack gear exposure groove 41. Whereby the rod support 50 protrudes or is immersed from the guide bar body 40 when the driven gear 60 rotates forward or reverse.

The drive gear assembly 70 includes a driven gear 71 engaged with each of the driven gears 60 and a pulley 72 wound around the driven gear 30 and connected to the multi- And a pulley spring 73 for applying an elastic force to reverse the initial state when the pulley 72 is rotated.

The driven gear 71 forms a single body with the pulley 72 and the pulley 72 is wound with a wire 35 extending from the multi- Thus, when the wire 35 is released from the pulley 72, the driven gear 71 is rotated and the driven gear 60 meshed with the driven gear 71 is rotated.

When the pulley 72 is rotated by the wire 35, the pulley spring 73 provides an elastic force in a direction in which the pulley 72 is reversely rotated. The pulley spring 73 is preferably a spring-loaded spring, and the spring housing 74 is integrated with the lower side of the pulley 72. In this case, one side of the spring winding spring is fixed to the center end of the spring housing 74 and the other side is fixed to the small portion of the gear inclination bracket 22 of the base bracket.

With the above structure, the wire 35 extends to the lower side of the fixing rod 31 in a state where the extension rod 32 is immersed in the fixing rod 31, and the wire 35 is kept wound around the pulley 72, (73) provides an elastic force in a direction in which the pulley (72) winds the wire (35).

The rod support rod 50 to be described later is completely immersed in the guide bar body 40 in a state where the wire 35 is completely wound on the pulley 72. In this state, the wheel T is located inside the bag body 10 And the interval between the pair of wheels T is the narrowest. Further, the wheel T maintains a state of being in close contact with the back surface of the bag body 10. That is, the wheel T is concealed in the upper part of the upper body that encloses the back body 10.

With the above structure, when the user extends the extension rod 32 from the fixed rod 31, the wire 35 is pulled inside the fixed rod 31 to rotate the pulley 72 in the reverse direction. Then, the driven gear 71 integrated with the pulley 72 reversely rotates the driven gear 60, and the rod support 50, which is gear-engaged with the driven gear 60, protrudes from the guide bar body 40. In this case, the interval between the wheels T supported by the end of the rod support 50 is gradually widened, and the distance between the wheel T and the bag body 10 is gradually widened. When the rod support 50 is fully protruded from the guide bar body 40, the gap between the wheels T becomes larger than the width of the bag body 10 as shown in FIGS. 4 and 5, It is in a state open from the back surface. In this case, the bag body 10 and the pair of wheels T form a wide triangle, so that the golf bag 100 is not raised or collapsed when the golf bag 100 is raised or moved.

Here, since the rod support 50 is three-dimensionally supported by the long guide bar body 40, the load of the golf bag applied to the rod support 50 is dispersed into the guide bar body 40.
