Hereinbelow, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. Throughout the drawings, the same reference numerals will refer to the same or like parts.

As shown inFIGS. 1 to 12, a cart-attachable mobile golf bag according to the present invention includes a golf bag100having a hard-shell structure and a cart200attached to the golf bag in a one-touch docking manner.

The golf bag100includes: a bag body10including an inner space portion11for storing golf clubs, a moving wheel12provided at each lower side thereof, and inner and outer handles; and a head cover20detachably attached to an upper portion of the bag body.

The bag body10and the head cover20are made of polycarbonate and ABS material such that when the golf bag is transported in the air, the golf bag protects safely the golf clubs without requiring a separate wrapping cover, unlike a soft material such as cloth, and also has sufficient durability.

The head cover20has a double lock structure in which: the head cover is provided with a coupling protrusion25protruding from a lower outer side thereof and rotatably inserted into a coupling recess15formed in an upper outer side of the bag body10such that the coupling protrusion and the coupling recess are engaged with each other to prevent separation; and the head cover is opened and locked by a separate circular lock30.

At this time, the coupling protrusion25of the head cover has a T-shaped cross-section, and the coupling recess15of the bag body is configured such that an insertion portion15ainto which the coupling protrusion is inserted and a locking portion15bpreventing separation of the coupling protrusion are connected to each other, whereby when the coupling protrusion25is inserted into and rotated in the coupling recess15, the coupling protrusion and the coupling recess are engaged to prevent separation. Furthermore, the head cover20is provided with a hook26at a side of a lower portion thereof, and the bag body10is provided with a hook recess16formed in a front surface thereof correspondingly to the hook such that the hook is inserted into the hook recess. Due to this configuration, the head cover is detached from the bag body10and then hooked thereto for storage by hanging the hook26in the hook recess16of the bag body. Herein, the hooked head cover20is stored in an inverted state such that various golf equipment, such as a club head cover, other accessories, and the like is stored in an inner space of the head cover.

Furthermore, instead of the head cover20, a cloth cover20′ is separately provided such that the cloth cover20′ is attached to the upper portion of the bag body in place of the head cover. The cloth cover20′ is provided at a center thereof with a waterproof zipper21such that the golf clubs in the bag body are conveniently taken out for use by opening the waterproof zipper without requiring removal of the cloth cover. Furthermore, the bag body10is provided at a front center thereof with a front door17. The front door is configured to be released by pressing of a button17aand is opened while being elastically rotated by an elastic spring such that various equipment is stored in a storing portion17b. Furthermore, the bag body10is provided at each side thereof with a metal plate18at a position inside a sidewall of the bag body, and a side pocket35having a magnet36is separately provided to store various equipment by being attached and detached by a magnetic force exerted by the magnet at a position outside the side wall of the bag body correspondingly to the metal plate.

At this time, the side pocket35is made of a cloth material so as to be easily carried in a folded state when not in use.

Furthermore, each of the respective moving wheels12of the bag body10is configured such that a wheel shaft31that has multiple annular grooves31aformed along a longitudinal direction thereof is inserted into the bag body10from each side of the bag body in an extendable and retractable manner, and a press pin33is protrudingly inserted into a side of each of the respective wheel shafts from a lower portion of the bag body in a direction perpendicular to the wheel shaft such that the press pin is inserted into a side of one of the grooves31aof the wheel shaft31to support the moving wheel12. Herein, each of the respective press pins33is provided with an annular grooved portion33acorresponding to the diameter of the wheel shaft such that when the grooved portion33ais moved into a position engaging the wheel shaft31by elastically pressing the press pin, the wheel shaft is extended by a width between the grooves31a, thus adjusting the width between the moving wheels12.

That is, due to adjustment of the width between the moving wheels12, it is possible that the golf bag is moved more stably when moving, and also the golf bag is minimized in volume when stored.

Herein, the press pin33is elastically supported by an elastic spring (not shown) such that when an external force is removed after a pressing operation, the press pin is returned to an original position by the elastic spring and thus supports the wheel shaft31of the moving wheel12again.

Furthermore, the bag body10is provided in a rear surface thereof with a supporting bar19inserted into an embedding groove19avertically formed in a longitudinal direction of the bag body. Herein, an upper end of the supporting bar is shafted to the embedding groove such that when the bag body is needed to stand upright, a lower end of the supporting bar is rotated to support the bag body in a standing upright position.

The cart200includes a vertical quadrangular support51, a handle52provided at an upper portion of the support, left and right moving wheels55provided at a lower portion of the support and connected to each other by a link member54, and a docking block56provided on a front surface of the cart and coupled to a docking recess60formed in a rear surface of the golf bag.

The docking block56has a T-shaped structure having a locking protrusion56aat each side thereof. The docking recess60includes an insertion recess61into which the docking block is inserted, and a locking recess62extending from a lower side of the insertion recess and having a locking step62aby which each of the respective locking protrusions56ais locked and retained. Due to such configuration, when the insertion recess61of the golf bag is fitted over the docking block and then the golf bag is slided downward to cause the locking recess62to be fitted over the docking block, the golf bag is attached to the cart in a one-touch docking manner.

At this time, it is preferable that each of the docking block56and the docking recess60is provided at least two positions in a vertical direction such that the respective docking blocks and the respective docking recesses correspond to each other.

Furthermore, each of the moving wheels55of the cart is provided with a brake means70for restricting movement of the moving wheel55. The brake means70includes an actuating lever72vertically rotated about a hinge shaft71by a pressing operation, an actuating pin73having a rear end shafted to a lower end of the actuating lever so as to be moved forward by the pressing operation of the actuating lever, and a rotation restricting recess58formed in a side surface of the moving wheel55and restricting rolling of the moving wheel55when the actuating pin moving forward is inserted thereinto.

The actuating pin73may have a simple pin structure. However, it is preferable that the actuating pin73has a cylinder structure as shown in the drawings and is guided to be moved forward or rearward by a guide.

Undescribed reference numerals81and82denote handles respectively provided at a front side and a rear side of the bag body.

Hereinafter, the operation and action of the present invention configured as described above will be described.

The golf bag100according to the present invention is used in combination with the cart200by storing golf clubs in the inner space11of the bag body10and then attaching the head cover20to the bag body, or is used while being moved by the moving wheels12without combination with the cart.

At this time, attachment of the head cover20is performed in such a manner that the coupling protrusion25formed in the lower outer side of the head cover and having a T-shaped cross-section is inserted into the coupling recess15formed in the upper outer side of the bag body10. In this manner, the coupling protrusion25is inserted into the insertion portion15aof the coupling recess and then the head cover is rotated to cause the coupling protrusion25to be positioned in the locking portion15bof the insertion portion, whereby the head cover is firmly attached to the bag body so as not to be separated therefrom.

Since the bag body10and the head cover20of the golf bag100are made of polycarbonate, an ABS material, and the like to have a hard-shell structure, it is possible that when the golf bag is transported by air, the golf bag protects safely the golf clubs inside without requiring a separate wrapping cover.

When the golf bag100according to the present invention is needed to be used in combination with the cart200, the docking block65of the T-shaped structure formed on the front surface of the support51of the cart is inserted into the insertion recess61formed in an upper portion of the docking recess60formed in the rear surface of the bag body.

Then, when the docking block56of the cart is slided downward into the locking recess62located at a lower location of the insertion recess61, the locking steps62aat opposite sides of the locking recess62lock the locking protrusions56aat opposite sides of the docking block56, whereby the golf bag is simply attached to the cart in a docking manner so as not to be separated therefrom. This makes it possible that the golf bag is simply and firmly attached to the cart in a one-touch manner without requiring any separate tying process as in the related art.

After the golf bag100is attached to the cart200in a docking manner as described above, the golf bag is used while being moved by the moving wheels55of the cart and the moving wheels12of the golf bag. Herein, to enable the golf bag100to be moved more stably, the moving wheels12of the golf bag100is adjusted in width.

This means that when each of the press pins33protruding outwardly from each side of the lower portion of the bag body is pressed, the press pin33, which is in a state of supporting the wheel shaft31to restrict an extending and retracting motion of the wheel shaft by being inserted into one of the grooves31aformed in the wheel shaft of the moving wheel12, transitions to a state of permitting the extending and retracting motion of the wheel shaft31when the grooved portion33aof the press pin is positioned on the wheel shaft.

In this state, when the wheel shaft31of the moving wheel12is extended to allow the remaining one of the grooves31aformed in the wheel shaft along the longitudinal direction thereof to be positioned on the press pin, and then the pressing operation of the press pin is removed, the press pin is elastically returned to the original position thereof. This causes a large-diameter portion of the press pin rather than the grooved portion33ato be inserted into the remaining one of the grooves31aof the wheel shaft, thus locking the wheel shaft31of the moving wheel12.

By controlling the extending and retracting motion of the left and right moving wheels12of the golf bag in such a manner, the golf bag is used by adjusting the width between the moving wheels12.

The golf bag100according to the present invention as described above is used while being easily moved in combination with the cart, and when the golf clubs in the bag body10are needed to be used, the head cover20is detached from the bag body and then the golf clubs are taken out.

At this time, the detached head cover20to be stored is hooked to the bag body by inserting the hook26provided at the side of the lower portion thereof into the hook recess16formed in the front surface of the bag body.

Herein, since the hooked head cover20is stored in an inverted state, various equipment, such as a club head cover, other accessories, and the like may be stored in the head cover.

Furthermore, the side pocket35may be attached to each side of the bag body10to store various equipment. This is realized by attaching the respective side pockets35to positions corresponding to the respective metal plates18provided in the side wall of the bag body10by a magnetic force exerted by the magnets36provided in the side pockets35.

The side pockets35are made of a cloth material and thus can be simply stored in a different storage space in a folded state when not in use.

On the other hand, as shown inFIG. 10, the separate cloth cover20′ is detachably attached to the upper portion of the bag body10in place of the head cover20. Herein, since the cloth cover20′ is provided with the waterproof zipper21at the center thereof, the golf clubs in the bag body can be simply taken out for use by opening the waterproof zipper without requiring detachment of the cloth cover.

Furthermore, when the golf bag100according to the present invention is used while being moved in combination with the cart200, it is possible that movement of the moving wheels55of the cart is restricted by the brake means70at a stationary position. This is realized in such a manner that when the actuating lever73provided at a side of each of the moving wheels55of the cart is pressed, the actuating lever73is rotated to cause the actuating pin73shafted to the lower end of the actuating lever72to be pressed and moved forward, and then the actuating pin73is inserted into the rotation restricting recess58formed in the side surface of the moving wheel55, thus restricting movement of the moving wheel55.

On the contrary, in a case where movement restriction of the moving wheels55is needed to be released, when the actuating lever72of the brake means70is pressed again, the actuating lever72is returned to the original position thereof while being rotated, causing the actuating pin73moved forward to be moved rearward back, thus permitting movement of the moving wheel55.

On the other hand, in a case where the cart200is needed to be detached from the golf bag100, in the reverse order of a docking operation, the docking block56of the cart is slided upward from the docking recess to be positioned in the insertion recess61located at an upper location of the locking recess62, and then the cart is pulled forward and simply detached.
