DETAILED DESCRIPTION OF THE INVENTION

(16) As illustrated in FIGS. 3 to 8, a club cover A having variable internal space by being configured to be flexible in an entrance space part thereof according to a first embodiment of the present invention includes: a head storage space 11 provided at an upper part of the club cover, the head storage space storing the club head H; a body part 12 provided from a middle to a lower part of the club cover and which the club head is inserted into and withdrawn from; and an entrance space part 13 provided inside the body part 12, the entrance space part being configured to be wide so as to easily pass the club head therethrough.

(17) The body part 12 includes: a front surface 12a and a rear surface 12b brought close to and spaced apart from each other while the entrance space part 13 is contracted and expanded; and side surfaces 12c1 and 12c2 connected to opposite sides of front and rear surfaces 12a and 12b therebetween.

(18) In the embodiment of the present invention, piping parts 121 are provided at connection portions of the front surface 12a of the body part 12 and the side surfaces 12c1 and 12c2 and connection portions of the rear surface 12b and the side surfaces 12c1 and 12c2; a magnet M is inserted into a lower part of each of the piping parts 121; and a magnet pocket 122 is attached to a middle part of the piping part 121. The magnet pocket 122 is attached to the piping part 121 via a pocket connection part 122a, and a magnet M is inserted into a pocket 122b provided at an end part of the pocket connection part 122a.

(19) As illustrated in FIGS. 4 and 8, the connection part is bent such that the magnet pockets 122 attached to the middle parts of the piping parts 121 are close to each other in a direction opposing each other, so attachment between the magnets M can be efficiently performed during the contraction of the body part.

(20) A handle 15 is provided at each of the connection portions of the front and rear surfaces 12a and 12b and the side surfaces 12c1 and 12c2, at which the magnet pockets 122 are provided, the handle being more rigid than the body part 12. The handle 15 prevents the magnet pockets 122 on the same plane from being attached to each other and allows the magnet pockets 122, which are attached to each other, to be easily separated from each other.

(21) According to the first embodiment of the present invention having the above-described structure, the operation of the club cover A having variable internal space by being configured to be flexible in the entrance space part thereof will be described in detail hereinbelow.

(22) First, when storing the club head H in the club cover A in an empty state in which the club head H is withdrawn from the inside thereof, as illustrated in FIG. 5, the attachment of the piping parts 121 of the front surface 12a and the rear surface 12b of the body part 12 is released; the front surface 12a and the rear surface 12b are spaced apart from each other; and the body part 12 is expanded with the side surfaces 12c1 and 12c2 spread, so that the entrance space part 13 is expanded. In this state, the club head H is inserted into the club cover. Then, the body part 12, which is expanded, is pushed by an external force to be contracted; the side surfaces 12c1 and 12c2, which are spread, are folded; and the front surface 12a and the rear surface 12b of the body part 12, which are spaced apart from each other, are brought close to each other.

(23) In this case, while the magnet pockets 122 of middle parts of the piping parts 121 opposed to each other formed on edges of the front surface 12a and the rear surface 12b are brought close to each other, the magnets M of the magnet pockets 122 are attached to magnets M of magnet pockets 122 of the body part 12 of the opposing side arranged at positions corresponding thereto. Accordingly, the opposing piping parts 121 of the positions corresponding to each other are easily and efficiently attached to each other. While the magnets M of the lower parts of the piping parts 121 are also brought close to each other, the magnets M are attached to each other and the entrance space part 13 of the body part 12 is contracted, so the club head H is stored in the club cover A.

(24) On the contrary, when withdrawing the club head H from the club cover A with the club head H stored therein, an external force is applied in a direction in which the front surface of a body 12a and the rear surface of a body 12b move away from each other while the magnets M of the magnet pockets 122 and the magnets M of the piping parts 121 are attached to each other. The magnets M attached to each other are separated from each other, and the entrance space part 13 of the body part 12 is expanded. Accordingly, the club head H can be withdrawn from the inside of the club cover A through the entrance space part 13, which is easily expanded.

(25) A distance spaced apart between each of the magnets M of the piping parts 121 is configured to be minimized. Accordingly, the magnets are attached to each other even by the small number of the magnets and thus the number of the magnets used can be reduced, so manufacturing cost is reduced. Furthermore, since the piping parts 121 are attached to each other, there is no open space therebetween, so foreign matter is prevented from being attached to the side surfaces of the club cover and from being introduced into the club cover, whereby there is no risk of malfunction and the appearance of the club cover A is clean and beautiful.

(26) FIG. 9 is partially cut front views illustrating the states of the expansion and contraction of a body part of a club cover according to a second embodiment of the present invention. Magnet pockets 122 are configured to be attached to lower parts and middle parts of the piping parts 121, respectively, by being spaced apart from each other at the lower parts and the middle parts of the piping parts 121. The entrance space part 13 provided inside the body part 12 is configured to be expanded and contracted by the detachment and attachment of the magnets M inserted into the pockets 122b of the magnet pockets 122.

(27) FIG. 10 is partially cut front views illustrating the states of the expansion and contraction of a body part of a club cover according to a third embodiment of the present invention. In the embodiment, as for a slanting magnet pocket 122 attached to each of piping parts 121, a magnet M is stored in a pocket 122b provided at an extending edge of a pocket connection part 122a as a single piece attached to the piping part 121 by extending to be slanted by the interval between opposing magnet pockets becoming bigger toward a middle part from a lower part thereof.

(28) As for the slanting magnet pockets 122, when the slanting magnet pockets opposing each other at opposite sides of the club cover are attached to each other, there is no space therebetween for dust or foreign materials to be inserted to, so the club cover A can be kept in a clean state.

(29) FIG. 11 is a perspective view of a club cover unfolded by being expanded according to a fourth embodiment of the present invention. In the embodiment, a cut part 16, in which the side surfaces 12c1 and 12c2 of a middle part of the body part 12 are entirely cut out, is formed. Accordingly, the club cover is configured to perform the function thereof by using only the front surface 12a and the rear surface 12b. Although not shown, a mesh structure may be provided on the side surfaces 12c1 and 12c2.

(30) In addition, instead of the magnets M or the magnet pockets 122 mounted to the piping parts 121, a connection means such as Velcro tape or a snap button may be used.

(31) FIGS. 12A, 12B, and 13 are front views of a club cover according to a fifth embodiment of the present invention. The cut part 16 is formed such that an extending protection part 16a extending from each of the piping parts 121 to the inside thereof is maintained; a cut-open part 16b is formed at an upper part of the cut part 16; and the magnet pocket 122 is configured to be still attached to the piping part.

(32) In the embodiment, the extending protection part 16a is maintained by extending by the width of 1 cm from each of the piping parts 121 to the center s of the body part 12; the remaining part is cut to form the cut part 16; and the cut-open part 16b is formed along the center s of the body part 12 at an end part of the extending protection part 16a.

(33) In the club cover A having such a structure, when the front surface 12a and the rear surface 12b are pulled to the outside, the cut part 16 is opened as illustrated in FIG. 13, and then the cut-open part 16b is also opened, and thus the storage space for a big club head H is formed. Accordingly, the club head H can be easily introduced into or withdrawn from the head storage space 11.

(34) FIGS. 14A and 14B are a front view of the contracted position of a club cover and a front view of the expanded position of the club cover, respectively, according to a sixth embodiment of the present invention. A flexible spandex fabric is attached to the cut part 16 of an inner side of the extending protection part 16a extending inward from each of the piping parts 121. Accordingly, the contracted position of the front surface 12a and the rear surface 12b can be extended. That is, when a flexible spandex fabric 15 is attached to the cut part 16 of the inner side of the extending protection part 16a as illustrated in FIGS. 14A and 14B, normally, the flexible spandex fabric 15 is arranged in a contracted state and the club head H is stored in the club cover A. When the club head H is withdrawn, the front surface 12a and the rear surface 12b are pulled. Then, while the spandex fabric 15 is extended, an interval between the front surface 12a and the rear surface 12b of the body part 12 is increased to allow the club head H to easily pass therebetween, so that the club head H can be easily withdrawn and after the withdrawal of the club head H, the spandex fabric 15 is contracted again and restored to the contracted position.

(35) As described above, in the club cover having variable internal space according to the present invention, the front and rear surfaces of the body part are spaced apart from and brought close to each other. Accordingly, the club head can be easily withdrawn and safely stored without damage.

(36) The club cover having variable internal space according to the present invention can be efficiently applicable to the club cover manufacturing industry, since it is possible to manufacture homogeneous products in the club cover manufacturing industry.
