HORIZONTALLY MOVABLE BOWLING BAG PROVIDING EASE OF USE AND MAINTENANCE

Description

BACKGROUND

The present invention relates to a bowling bag that is horizontally movable in a state of storing a plurality of bowling balls, and more particularly to a horizontally movable bowling bag providing ease of use and maintenance, which is capable not only of safely transporting a plurality of bowling balls in a state of stably storing and supporting the bowling balls, but also of facilitating replacement of casters thereof, which are frequently damaged.

In general, people play golf in golf practice facilities or on golf courses. Golf has been regarded as one of the noble sports with high dignity, and therefore golfers wear appropriate golf attire and golf shoes, rather than casual clothes. Golf attire and golf shoes are respectively carried in a state of being stored in a bag and a shoe pouch, and are worn in golf practice facilities or on golf courses.

In this case, however, because golf attire and golf shoes are separately carried, the number of pieces of baggage to be carried by a golfer is large, which causes inconvenience to the golfer.

Therefore, many golfers put a shoe pouch containing golf shoes into a bag in which golf attire is contained in order to reduce the number of pieces of baggage to be carried.

However, in the case in which golf shoes are stored in a bag together with golf attire, foot odor in the golf shoes leaks through ventilation holes formed in the shoe pouch, and then clings to the golf attire, which makes the golfer feel unpleasant when wearing the golf attire and causes poor hygiene.

Korean Utility Model Registration No. 381977 discloses a golf travel bag capable of preventing the above problems. As shown in FIG. 1, the golf travel bag includes a main body 300, a suit pocket 2 provided in the main body 300 so as to be opened and closed by means of a zipper from the outside of the main body 300, a cover 200 provided on the upper side of the main body 300 so as to be opened and closed by means of a zipper, a handle 400 mounted to one side of the main body 300 and formed to be adjustable in length in a telescopic manner, casters 500 mounted to the lower side of the main body 300, and support protrusions 600 formed on the lower surface of the main body 300 at positions aligned with the casters 500.

In addition, the golf travel bag further includes a shoe pocket 6 provided in a side surface of the main body 300 to store shoes in a space defined on the inner bottom surface of the main body 300, a cover 64 provided on the side surface of the main body 300 to open and close the shoe pocket 6, the cover 64 being formed to be opened and closed by means of a zipper, a handle pocket 7 provided under the shoe pocket 6 to receive the handle 400 when the handle 400 is reduced in length in a telescopic manner, and a cover 74 provided on the side surface of the main body 300 to open and close the handle pocket 7, the cover 74 being formed to be opened and closed by means of a zipper 72. When the handle 400 is received in the handle pocket 7, the cover 74 shields the handle 400 to make the same invisible.

However, in the golf travel bag described above, the casters 500 are mounted only to one side of the lower surface of the main body 300, which causes attire organized in the suit pocket to become tangled during movement of the golf travel bag.

In addition, because the casters 500 are integrally mounted to the lower surface of the main body 300, a user experiences inconvenience of having to replace the main body 300 in the event of damage to the casters 500.

In addition, although it is possible to place a separate auxiliary bag on the main body 300 in order to carry additional articles, such as balls, the golf travel bag does not have a separate device for firmly coupling the auxiliary bag to the main body 300, and therefore it is difficult to securely fix the auxiliary bag to the main body 300.

In addition, the auxiliary frame 430 of the auxiliary bag 400 has fixing projections 431 protruding from the lower surface thereof and screw holes 432 formed in the lower surface thereof. When the auxiliary bag 400 is placed on the frame 110, the fixing projections 431 are supported by the grid-shaped ribs 145 formed on the upper surface of the frame 110, and the screw holes 432 are aligned with screw holes in coupling bosses 119 formed on the upper surface of the frame 110. In this state, screws are fastened into the screw holes 432 and the screw holes formed in the coupling bosses 119 of the frame 110, whereby the auxiliary bag 400 is firmly fixed to and supported by the frame 110.

The operational effects of the present invention configured as described above will be described below.

As shown in FIGS. 2 to 27, the frame 110 of the bowling bag 100 of the present invention has a predetermined shape in which one or more storage spaces S are defined. Since the frame 110 is made of a plastic material having predetermined strength, a plurality of bowling balls B or other bowling supplies 900, such as bowling attire or bowling shoes, may be stored in the storage spaces S in the frame 110.

The frame 110 is formed as a unitary body, or is formed in such a manner that constituent elements thereof are individually manufactured and then are assembled with each other. In the case in which the frame 110 is a side-reception-type frame, as shown in FIGS. 14 to 16, the storage space S is partitioned into a plurality of storage spaces by one or more partition plates 139, which are integrally formed with the frame 110 or are separately provided and assembled to the inner side of the frame 110 in the horizontal direction or the vertical direction, and therefore the plurality of bowling balls B is introduced into the plurality of storage spaces from both sides of the frame 110 and is stored therein.

In addition, the frame 110 is formed in a 90°-rotated U shape or an L shape when viewed in a side view such that the ball support 150 coupled to the inner side thereof has predetermined strength, and the cover 200, which is made of a fabric material, is connected to the front side of the frame 110, whereby the overall weight of the bowling bag 100 of the present invention may be reduced.

In addition, the frame 110 has increased strength and reduced weight due to the plurality of ribs 145 integrally formed therewith on the upper surface and the lower surface thereof.

In the case in which the cover 200 is connected to the front side or both sides of the frame 110 to form a hexahedral shape overall together with the frame 110, it is possible to take the bowling balls out of the bowling bag 100 at a position ahead of the bowling bag 100 through the door 210 provided at the cover 200 so as to be oriented in the forward direction or to take the bowling balls out of the bowing bag 100 at positions on both sides of the bowling bag 100 through the doors 210 provided at the cover 200 so as to be oriented in the lateral direction.

The door 210 provided at the cover 200 is oriented toward the front side or at least one of both sides of the frame 110, and is formed to be opened and closed by means of a zipper. Accordingly, it is easy to store and take the bowling balls in and out of the frame 110 through the door 210.

As shown in FIGS. 14 and 17, the cover 200 is made of a fabric material, and thus is connected to edges of the front side or both sides of the frame 110 in a sewing manner, a zipper-coupling manner, a rivet-coupling manner, a screw-coupling manner, a button-coupling manner, or the like.

The cover 200 is separately manufactured corresponding to the frame 110, and is connected to the frame 110 to form the overall shape of the bowling bag 100.

As shown in FIG. 24, the resilient support member 650 integrally formed with the door 210 of the cover 200 has therein a tight contact recess formed corresponding to the shape of the bowling ball. Accordingly, when the door 210 is closed, the tight contact recess in the resilient support member 650 is brought into tight contact with one side of the bowling ball supported by the ball support 150, thereby preventing shaking of the bowling ball and firmly supporting the bowling ball when the bowling bag 100 is moved horizontally.

In addition, as shown in FIG. 14, one or more auxiliary handles 280, which are made of a fabric material, are sewn to the cover 200. Accordingly, when a user pulls the bowling bag 100 using the handle 190 or loads a bowling ball in the bowling bag 100, he or she may additionally use the auxiliary handles 280 to hold the frame 110.

In addition, the door 210 formed at the cover 200 has one or more pockets 215 protruding outwards from the cover 200 and formed to be opened and closed by means of a zipper or the like in order to store various bowling supplies 900.

Since the plurality of casters 300 is provided on the lower surface of the frame 110, the bowling bag 100 may be moved horizontally. In detail, the casters 300 enable a user to easily pull the bowling bag 100 using the handle 190 in the state in which the bowling bag 100 is inclined, as shown in FIG. 9, or to easily push the bowling bag 100 in the horizontal direction so that the bowling bag 100 is moved parallel to the ground. That is, the casters 300 reduce force needed to pull or push the bowling bag 100.

Since each of the casters 300 is provided on one side thereof with the brake unit, the bowling bag 100 is prevented from undesirably moving away from a desired location.

Each of casters 300 is connected to the frame 110 through the support hole 160 formed in one side of the frame 110, and is secured to the frame 110 by means of the coupling member 350. The coupling member 350 enables firm coupling and easy separation of each of the casters 300 to and from the frame 110, thereby facilitating repair and maintenance of the casters 300.

In addition, since one or more ball supports 150 are provided in the frame 110 to support one or more bowling balls B in the horizontal direction or the vertical direction, it is possible to prevent shaking of the bowling balls B when the bowling bag 100 is moved horizontally in the state in which the bowling balls B are loaded therein.

The ball support 150 may be assembled to the fixing block 130, which is formed so as to protrude from the inner side of the frame 110, in an interference-fit manner or a screw-coupling manner, as shown in FIG. 22, or may be formed on the inner side surface of the frame 110.

In the case in which the ball support 150 is formed on the inner side surface of the frame 110, the ball support 150 is integrally formed with the frame 110.

In addition, the shaking prevention member 600 integrally formed with the ball support 150 functions to prevent shaking of the bowling ball disposed on the upper surface or one side of the ball support 150 when the frame 110 is moved horizontally.

As one embodiment of the shaking prevention member 600, as shown in FIG. 2, the tension portion 610 is formed by cutting a portion of the ball support 150 along the incision line 613 so as to be resiliently bendable relative to the portion of the ball support 150. Further, the tension portion 610 has the protrusion 611 formed on the upper surface thereof. Accordingly, it is possible to easily load the bowling ball on the ball support 150 and to reliably support the bowling ball.

In this case, the protrusion 611 is integrally formed with the ball support 150, is attached thereto, or is assembled therewith in a fitting manner.

As another embodiment of the shaking prevention member 600, as shown in FIG. 23, the safety-belt-type support belt 630 is mounted to the front side of the ball support 150. The support belt 630 is formed to be fastened and released and has the tension adjustment knob 631 for adjusting the tension thereof, thereby preventing the bowling ball from escaping from the ball support 150 in the forward direction. Accordingly, it is possible to reliably support the bowling ball, thus preventing overturn or non-smooth movement of the bowling bag 100 due to shaking of the bowling ball during horizontal movement of the bowling bag 100.

As still another embodiment of the shaking prevention member 600, as shown in FIG. 24, the resilient support member 650, which is made of a sponge material, is provided so as to protrude from the inner side of the cover 200. The resilient support member 650 functions to support the bowling ball more reliably together with at least one of the above-described embodiments of the shaking prevention member. Alternatively, the resilient support member 650 alone supports the bowling ball loaded on the ball support 150. Accordingly, it is possible to prevent shaking of the bowling ball during horizontal movement of the bowling bag 100.

In addition, as shown in FIG. 26, the storage chamber 360 for storing bowling supplies such as bowling shoes is provided in one side of the frame 110 so as to be isolated from the space for loading the bowling ball therein, thereby making it possible to store bowling shoes as well as the bowling ball in the frame 110.

As shown in FIG. 27, a portion of the upper surface of the frame 110 is open so as to communicate with the storage chamber 360, and the chamber door 361 is connected to the upper surface of the frame 110 to open and close the storage chamber 360. The chamber door 361 is of a one-touch opening and closing operation type, and is coupled to the frame 110 so as to be opened and closed from above. Accordingly, it is possible to easily store and take bowling shoes in and out of the storage chamber 360 without the necessity to open the door 210.

In addition, as shown in FIG. 22, the reinforcing plate 138 is provided on the inner side of the frame 110 in order to firmly support the cover 200 in the horizontal direction and the vertical direction. In the case in which the cover 200 having the doors 210 coupled to the upper and lower portions and both sides thereof is connected to the frame 110, the reinforcing plate 138 prevents separation or deformation of the cover 200 when the doors 210 are opened and closed.

As shown in FIG. 14, the frame 110 and the cover 200 may constitute the bowling bag 100 capable of loading a plurality of bowling balls therein in the lateral direction thereof. In this case, the bowling bag 100 may have a configuration selected from among:
