Description

[Technical Field]

[0001] The present invention relates to a head cover suitable for use with an iron. [Background technology]

[0002] Irons are often used without head covers and simply placed in a golf bag (caddy bag). Therefore, when playing or transporting the club heads, they collide with each other, easily causing scratches on the face and back of the club heads. In particular, there are multiple corners on the back of the club head, and when transporting or returning the iron to the golf bag, the backs of the club heads come into contact with each other, making the backs more susceptible to scratches than the face surfaces, and such scratches become more noticeable after long-term use. Therefore, for players who have purchased expensive irons, such scratches can be unbearable. On the other hand, irons are usually kept in a golf bag with four to six clubs ranging from a No. 5 iron, No. 6 iron, No. 7 iron to a pitching wedge, and if head covers are attached to the club heads of all the irons, it will be difficult to tell which iron is the number you want to use, which will interfere with your play. Some head covers have the club number printed on them, but because each head cover is large, it takes up a lot of space when all the club numbers are placed in the caddy bag, making it difficult to take out the club number you need and sometimes damaging the zipper on the caddy bag hood cover. To solve this problem, a head cover has been provided in which an opening is provided in the sole surface at a location on the head cover that corresponds to the number representing the club head number, and this opening is closed with a thin plate made of transparent silica gel.

[Effects of the Invention]

[0006] According to one embodiment of the present invention, scratches on the club head can be prevented, and the club head number can always be seen through the opening even after long-term use, which is advantageous in increasing the practical value and commercial value of the head cover. In addition, the cover piece for attaching and detaching the club head is made of an elastic material, so when inserting the club head into the head cover or removing it from the head cover, the cover piece for attaching and detaching the club head can be stretched to easily attach and detach the head cover, which is advantageous in increasing the practical value and commercial value of the head cover. According to one embodiment of the present invention, the leading edge is positioned relative to the head cover by the first protrusion, and the toe edge is positioned by the second protrusion. The extension direction of the first protrusion is interrupted in part, and a straight edge of the first cover section is located at the interrupted point. The opening is composed of the straight edge and a notch formed in the end of the second cover section, and one side of the opening is set based on the extension direction of the first protrusion. Therefore, when the golf club head is attached to the head cover, the number indicating the club head number is always located within the opening and is always visible. Therefore, during a round at the golf course or at a golf driving range, it becomes possible to easily and reliably take out the golf club of the number to be used from the golf bag, preventing scratches on the club head and allowing the number of the club head to be always visible through the opening even after long-term use, which is advantageous in increasing the practical value and commercial value of the head cover. Furthermore, according to one embodiment of the present invention, the edge of the cutout is formed by folding back a portion of the outer fabric of the second cover section near the edge and folding it in half, and by folding back a portion of the inner fabric of the second cover section near the edge and folding it in half, and then joining these folded portions together, so that the edge of the cutout is twice as thick as the second cover section and is thicker than the thickness of the other second cover sections. Therefore, it is easy to hook the tip of the index finger around the edge of the cutout, and since the second cover part is made of flexible fabric, it is easy to insert the tip of the index finger into the opening from the edge of the cutout. Therefore, the head cover can be easily and reliably moved by inserting the index finger into the opening, hooking the pad of the first joint of the index finger on the edge of the cutout, and moving the index finger along the toe edge of the club head. This is advantageous in that the club head can be removed easily and reliably, and is advantageous in that the practical value of the head cover is significantly improved. Furthermore, according to one embodiment of the present invention, the thickness of the second cover section is greater than the thickness of the first cover section, which is advantageous in protecting the back of the club head, which is easily damaged during transportation or when returning the iron to the golf bag. Furthermore, according to one embodiment of the present invention, the cover main body can also be constructed by adding decorative segments to the first cover segment and the second cover segment, and adding decorative segments is advantageous in enhancing the design of the head cover. Furthermore, according to one embodiment of the present invention, the hosel portion is covered by the first hosel portion covering piece, the second hosel portion covering piece, and the club head attachment / detachment cover piece. In other words, the head cover covers all parts of the club head, which is advantageous in protecting the entire club head during transportation or when returning the iron to the golf bag. In addition, the attachment / removal opening is formed large and consists of a first gap and a third gap, and the cover piece for attaching and removing the club head is stretchable, which is advantageous in making it easy to attach and remove the head cover and in increasing the practical value and commercial value of the head cover. Furthermore, according to one embodiment of the present invention, the thickness of the first cover section and the thickness of the second cover section may be different; for example, making the thickness of the first cover section greater than the thickness of the second cover section is advantageous in terms of protecting the face surface. Furthermore, according to one embodiment of the present invention, if a detachable lid body bearing a number indicating the club head number is provided separately from the head cover that closes the opening, then on rainy days, the head cover can be used with the lid body closing the opening, which is advantageous in preventing the club head from getting wet on rainy days.

DETAILED DESCRIPTION OF THE INVENTION

[0008] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In this embodiment, the head cover 12 is for an iron, and first, the names of the parts of the iron club head 14 will be described with reference to FIGS. 8(A) to 8(D). The club head 14 has a head body 14A and a cylindrical hosel portion 14B that protrudes from the head body 14A and to which a shaft 16 is coupled. The head body 14A includes a face surface 1402 that strikes the golf ball, a back surface 1404 located opposite the face surface 1402, a blade portion 1406 that connects the upper portion of the face surface 1402 to the upper portion of the back surface 1404, a sole surface 1408 that connects the lower portion of the face surface 1402 to the lower portion of the back surface 1404, a toe portion 1410 that connects the end of the face surface 1402 to the end of the back surface 1404 on the hosel side, and a heel portion 1412 that connects the end of the face surface 1402 away from the hosel portion 14B to the end of the back surface 1404. The ridge where the face surface 1402 and the sole surface intersect is called a leading edge 1414 , and the ridge where the face surface 1402 and the toe 1410 intersect is called a toe edge 1416 .

[0009] As shown in FIGS. 2 and 7, the head cover 12 is attached to the club head 14 and comprises a cover body 18 and a cover piece 20 for attaching and detaching the club head. An opening 22 for attaching and detaching the club head 14 is provided between the end of the cover body 18 and the end of the cover piece 20 for attaching and detaching the club head, and an opening 24 is provided in the cover body 18, which exposes the number representing the club head 14 to the outside of the cover body 18 and has no member covering the number.

[0010] As shown in Figures 6 to 8, the cover main body 18 covers the rest of the club head 14 except for the heel portion 1412 side of the blade portion 1406 of the club head 14 and the hosel portion 14B connected to the heel portion 1412 side of the blade portion 1406. The cover main body 18 may be made from a single piece of material, but in this embodiment, as shown in Figures 5 and 7, the cover main body 18 is formed from two pieces: a first cover section 26 that covers the face surface 1402 side of the club head 14, and a second cover section 28 that covers the back surface 1404 side of the club head 14.The shape of the cover main body 18 is designed to conform to the shape of the club head 14 when the club head 14 is inserted therein, as shown in Figures 1, 3, 5, and 7, so that the head cover 12 fits the club head 14. In detail, the first cover part 26 has a face surface covering piece 26A that covers the face surface 1402, and a first hosel portion covering piece 26B that is connected to the face surface covering piece 26A and covers the portion of the hosel portion 14B that connects to the face surface 1402. The second cover section 28 has a back cover piece 28A that covers the remaining part of the head main body 14A except for the face surface 1402, and a second hosel portion cover piece 28B that is connected to the back cover piece 28A and covers the part of the hosel portion 14B that connects to the back surface 1404. In more detail, the back surface covering piece 28A covers the back surface 1404, the blade portion 1406, the sole surface 1408, the toe portion 1410, and the heel portion 1412. Since the pitching wedge club head 14 is the largest among irons, the head cover 12 is designed to have a shape that matches the shape of the pitching wedge club head 14 when the pitching wedge club head 14 is inserted inside. Furthermore, since the face surface 1402 is flat, as shown in Figures 1 and 3, the area where the first cover section 26 covers the face surface 1402 is flat, and the area where the second cover section 28 covers the back surface 1404 is three-dimensional because it covers not only the back surface 1404 but also the blade portion 1406, toe portion 1410, and sole surface 1408; therefore, the first cover section 26 and the second cover section 28 have asymmetrical shapes at the boundary of their joint.

[0011] As shown in Figures 6 and 7, the cover piece 20 for attaching and detaching the club head is joined to the cover body 18 and covers the heel portion 1412 side of the blade portion 1406 and the hosel portion 14B connected to this portion. The cover piece 20 for attaching and detaching the club head is made of a material having elasticity and flexibility, such as knit. The thickness of the cover piece 20 for attaching and detaching the club head is within the range of 2 to 5 mm. When the head cover 12 is attached to the club head 14, the first hosel portion covering piece 26B and the second hosel portion covering piece 28B face each other and cover the entire length of the hosel portion 14B and the portion of the shaft 16 that is connected to the hosel portion 14B and is close to the hosel portion 14B. In detail, as shown in FIG. 7, when the head cover 12 is attached to the club head 14, the tip of the face surface covering piece 26A away from the head body 14A and the tip of the back surface covering piece 28A face each other with a first gap S1 between them, and in the portion facing the half of the blade portion 1406 on the heel portion 1412 side of the club head 14 and the portion facing the part of the hosel portion 14B connected to the half of the blade portion 1406 on the heel portion 1412 side, the face surface covering piece 26A and the back surface covering piece 28A, and the first hosel portion covering piece 26B and the second hosel portion covering piece 28B are not joined and face each other with a second gap S2 between them. When the head cover 12 is attached to the club head 14, the cover piece 20 for attaching and detaching the club head is joined to the face surface covering piece 26A and the back surface covering piece 28A so as to close the portion of the second gap S2 closer to the head body 14A, leaving a third gap S3, which is the portion of the second gap S2 closer to the first gap S1, and is also joined to the first hosel portion covering piece 26B and the second hosel portion covering piece 28B, covering the portion of the blade portion 1406 on the heel portion 1412 side and the entire length of the hosel portion 14B connected to this portion. The insertion / removal opening 22 is formed by a first gap S1 and a third gap S3.

[0012] The first cover section 26 and the second cover section 28 that constitute the cover main body 18 are formed from the same material. The cover body 18 can be made of various conventionally known materials that are used for the head cover 12 . 9, nylon, polyester, laminate (polyvinyl chloride laminated to the surface of fabric such as cotton or linen) and the like can be used as the outer fabric forming the surface of first cover section 26 and second cover section 28. These surfaces are water-repellent by coating with silicone or fluorine, etc., to make the surface water-repellent and flexible. Alternatively, vinyl chloride or synthetic rubber is used as the outer fabric, and a waterproof coating is applied with paraffin or the like to fill in the gaps in the fabric, making the surface waterproof and flexible. Furthermore, the lining that forms the back surface is made of a water-absorbent and flexible material such as polyester or rayon. The thickness of the outer fabric is within 2 to 5 mm, and the thickness of the inner fabric is within 4 to 10 mm. Furthermore, the thickness of the head cover 12 removed from the club head 14 is 10 to 30 mm because a space exists between the first cover section 26 and the second cover section 28. The weight of the head cover 12 is 15 to 50 g.

[0013] The edges of the first cover section 26 and the second cover section 28 may be joined by sewing them together with thread or by bonding them with various conventionally known adhesives. When using thread, threads made of various conventionally known materials such as nylon and cotton can be used. In the present invention, joining includes both sewing them together with thread and bonding them with adhesives. In this embodiment, multiple pieces of fabric are sewn together using thread, and the location J sewn together with the thread is indicated by a center line in the drawing. The first cover section 26 and the second cover section 28 may be of the same thickness, but in this embodiment, the thickness of the second cover section 28 is greater than the thickness of the first cover section 26. Here, the outer fabric of the first cover section 26 is referred to as first outer fabric 30, the inner fabric of the first cover section 26 is referred to as first inner fabric 32, the outer fabric of the second cover section 28 is referred to as second outer fabric 34, and the inner fabric of the second cover section 28 is referred to as second inner fabric 36. To explain this in detail, the first inner fabric 32 and the second inner fabric 36 are made of material of the same thickness, and the second outer fabric 34 is made of a material that is thicker than the first outer fabric 30. In this embodiment, the first cover section 26 has a thickness of 2 mm to 5 mm including the first outer fabric 30 and the first inner fabric 32 combined, and the second cover section 28 has a thickness of 4 mm to 10 mm including the second outer fabric 34 and the second inner fabric 36 combined. That is, the thickness of the second cover section 28 is made approximately twice the thickness of the first cover section 26, so that the back surface 1404 of the club head 14 will not be scratched even with long-term use.

[0014] As shown in Figures 5 to 7, when the head cover 12 is attached to the club head 14, the first cover section 26 and the second cover section 28 are joined on an imaginary extension plane of the face surface 1402 at the portions covering the face surface 1402 and the back surface 1404, and are joined continuously to the joined portion at the portion covering the hosel portion 14B. In other words, the face surface covering piece 26A and the back surface covering piece 28A are joined on an imaginary extension plane of the face surface 1402, and the first hosel portion covering piece 26B and the second hosel portion covering piece 28B are joined continuously to the joined point. In detail, as shown in Figure 9, on the imaginary extension plane of the face surface 1402, the portion near the edge of the first cover section 26 is folded back into the inside of the head cover 12, and the portion near the edge of the second cover section 28 is folded back into the inside of the head cover 12, and these folded back portions are joined inside the head cover 12 to form a joining protrusion 38 that protrudes into the inside of the head cover 12 and extends along the imaginary extension plane of the face surface 1402.

[0015] In this embodiment, a pair of decorative bands 4004 are provided on the joining ridge 38, in which narrow decorative segments 40 are folded in half and overlapped, and connected at a bent portion 4002 that sandwiches a flexible synthetic resin rod 42. That is, the cover main body 18 is made up of the first cover segment 26, the second cover segment 28, and the decorative segments 40. In this embodiment, the decorative section 40 is made of the same material as the first outer fabric 30 of the first cover section 26. Such decorative divided pieces 40 may be omitted, but using the decorative divided pieces 40 is advantageous in improving the design of the head cover 12. In detail, the joining protrusion portion 38 is composed of a first folded portion 3002 in which a portion near the edge of the first outer fabric 30 of the first cover section 26 is folded back into the inside of the head cover 12, a second folded portion 3402 in which a portion near the edge of the second outer fabric 34 of the second cover section 28 is folded back into the inside of the head cover 12, a pair of decorative bands 4004 that are superimposed on the surfaces of the first folded portion 3002 and the second folded portion 3402 with the folded portion 4002 positioned outside the head cover 12, and an edge portion 3202 of the first lining fabric 32 of the first cover section 26 and an edge portion 3602 of the second lining fabric 36 of the second cover section 28 that are sandwiched between the pair of decorative bands 4004. Therefore, in this embodiment, the joining protrusion portion 38 is formed by the ends of the first outer fabric 30 and the second outer fabric 34 folded inside the head cover 12, a pair of decorative bands 4004 sandwiching the rod 42, and the ends of the first lining fabric 32 of the first cover section 26 and the second lining fabric 36 of the second cover section 28 that cover the ends of the first outer fabric 30 and the second outer fabric 34.

[0016] In addition, when the decorative partition 40 is omitted, as shown in Figure 10, the joining protrusion portion 38 is formed by sandwiching and joining the portion of the overlapping first lining fabric 32 near the edge 3202 and the portion of the second lining fabric 36 near the edge 3602 between a first folded portion 3002 in which the portion of the first outer fabric 30 of the first cover partition 26 near the edge is folded back inside the head cover 12, and a second folded portion 3402 in which the portion of the second outer fabric 34 of the second cover partition 28 near the edge is folded back inside the head cover 12.

[0017] Here, the joining protrusions 38 will be described in detail. The joint ridge portion 38 is configured by a first ridge portion 42, a second ridge portion 44, a third ridge portion 46, and a fourth ridge portion 48 that are provided in succession. As shown in FIG. 14, the first protrusion portion 42 is capable of contacting the end of the sole surface 1408 on the leading edge 1414 side where the face surface 1402 and sole surface 1408 of the club head 14 intersect, and extends along the sole surface 1408 so as to guide the end of the sole surface 1408 into the inside of the club head 14 when the head cover 12 is attached to the club head 14. As shown in FIG. 15, the second protrusion 44 is formed so as to be able to contact the end of the toe portion 1410 on the toe edge 1416 side where the face surface 1402 of the club head 14 intersects with the toe portion 1410, extend along the toe portion 1410, and determine the insertion limit of the toe portion 1410. As shown in Figures 5 and 6, the third protrusion portion 46 is formed so as to be positioned at a portion of the head cover 12 opposite the portion of the hosel portion 14B continuing from the sole surface 1408 of the club head 14, with the end of the sole surface 1408 on the leading edge 1414 side contacting the first protrusion portion 42 and the toe edge 1416 contacting the second protrusion portion 44. As shown in FIGS. 6 and 7, the fourth protrusion 48 is formed so as to be located at a portion of the head cover 12 opposite the portion of the blade portion 1406 on the toe side. The first protrusion portion 42 and the second protrusion portion 44 are arranged continuously, the first protrusion portion 42 and the third protrusion portion 46 are arranged continuously, and the second protrusion portion 44 and the fourth protrusion portion 48 are arranged continuously.

[0018] As shown in FIGS. 1 and 5, the first protrusion 42 is interrupted in part in its extending direction, and an opening 24 is provided at this interrupted location. That is, at this interrupted point, a straight edge portion 2602 of the first cover section 26, which extends continuously in a straight line along the edge portion of the first cover section 26 that constitutes the first protrusion portion 42, is located. A notch 2802 is formed at the end of the back cover piece 28A of the second cover part 28 in an open manner relative to the straight edge portion 2602, exposing the numbers, and the opening 24 is formed by the straight edge portion 2602 and the notch 2802. 11, the straight edge 2602 is formed by joining a first folded portion 3002 where the first outer fabric 30 of the first cover section 26 is folded back inside the head cover 12, one decorative band 4004 of the decorative section 40 that sandwiches the rod 42, and a folded portion 3204 where the first inner fabric 32 of the first cover section 26 is folded back inside the head cover 12. In this embodiment, this joining is performed by stitching, and the location sewn with the thread is indicated by the symbol J in FIG. 12, the straight edge 2602 where the opening 24 is located is formed by joining the end of the first outer fabric 30 of the first cover section 26 folded back inside the head cover 12 to the end of the first lining fabric 32 of the first cover section 26 folded back inside the head cover 12, and in this case, the folded back end of the first outer fabric 30 is positioned to protrude further than the folded back end of the first lining fabric 32. In this embodiment, this joining is performed by stitching with thread, and the location where the stitching is performed is indicated by the symbol J in FIG. The size of the opening 24 is 200 to 800 mm 2 is.

[0019] As shown in Fig. 13, the notch 2802 is formed by joining an end of the second outer fabric 34 folded in half to an end of the second lining fabric 36 folded in half. In this embodiment, this joining is performed by stitching, and the location stitched with the thread is indicated by the symbol J in Fig. 13. As shown in FIG. 5, the cutout 2802 has two edges 2802A and 2802B that face each other in the extension direction of the straight edge portion 2602, and a connecting edge 2802C that connects the tips of the edges 2802A and 2802B. Of the two facing edges 2802A and 2802B, the edge 2802A that is farther from the attachment / detachment opening 22 is the finger hook edge 2802A.

[0020] Next, the procedure for attaching and detaching the head cover 12 to and from the club head 14 will be described. (Attaching the head cover 12) When attaching the head cover 12 to the club head 14, for example, with the club head 14 oriented so that the toe portion 1410 is away from the body and the heel portion 1412 is close to the body, the shaft 16 portion near the club head 14 is grasped with the left hand, and the attachment / detachment opening 22 portion of the head cover 12 located at the end of the third protrusion portion 46 is grasped with the right hand. Alternatively, the right hand is used to grip the shaft 16 near the club head 14 with the back surface 1404 facing the front of the body, and the left hand is used to grip the first protrusion 42 and the second protrusion 44. Then, the corner of the toe part 1410 and the blade part 1406 of the club head 14 is inserted into the attachment / detachment opening 22, and the club head 14 is inserted into the attachment / detachment opening 22 while the corner of the toe part 1410 and the blade part 1406 of the club head 14 pushes and spreads the club head attachment / detachment cover piece 20, or the head cover 12 is attached to the club head 14. In either case, when inserting the club head 14 into the head cover 12 or when attaching the head cover 12 to the club head 14, as shown in Figure 14, the end of the sole surface 1408 on the leading edge 1414 side inside the head cover 12 is guided by the first protrusion portion 42 and the portion 2610 of the first cover section 26 that connects to the first protrusion portion 42, as the club head 14 enters the inside of the head cover 12, and eventually the end of the toe portion 1410 on the toe edge 1416 side engages with the second protrusion portion 44 and the portion of the first cover section 26 that connects to the second protrusion portion 44.

[0021] In this state, as shown in Figure 14, the end of the sole surface 1408 on the leading edge 1414 side engages with the first protrusion portion 42 and the location 2610 of the first cover section 26 that connects to the first protrusion portion 42 along the entire length of the leading edge 1414, and as shown in Figure 15, the end of the toe portion 1410 on the toe edge 1416 side engages with the second protrusion portion 44 and the location 2612 of the first cover section 26 that connects to the second protrusion portion 44 along the entire length of the toe edge 1416, thereby completing the insertion of the club head 14 into the head cover 12 and resulting in the head cover 12 being attached to the club head 14.

[0022] (Removal of head cover 12) When removing the head cover 12 from the club head 14, grip the shaft 16 near the club head 14 with either the right or left hand, insert the index finger of the other hand into the opening 24 from the finger hook edge 2802A as shown in FIG. 13, hook the pad of the tip of the first joint of the index finger around the finger hook edge 2802A inside the opening 24, and move the index finger along the toe edge 1416 of the club head 14. This causes the club head attachment / detachment cover piece 20 to be spread apart by the blade portion 1406 on the heel side of the club head 14, and the head cover 12 is removed from the club head 14.

[0023] The head cover 12 of this embodiment provides the following effects. As shown in Figure 5, an opening 24 is formed in the cover body 18 of the head cover 12, which exposes the numbers representing the club head 14 number formed on the sole surface 1408 of the club head 14 to the outside of the cover body 18 and does not have any material covering the numbers. Therefore, the club head 14 can be prevented from being scratched, and the club number of the club head 14 can always be seen through the opening 24 even after long-term use, which is advantageous in increasing the practical value and commercial value of the head cover 12.

[0024] In addition, the cover piece 20 for attaching and detaching the club head is made of a stretchable material, so when inserting the club head 14 into the head cover 12 or removing it from the head cover 12, the cover piece 20 for attaching and detaching the club head can be stretched to easily attach and detach the head cover 12, which is advantageous in increasing the practical value and commercial value of the head cover 12. Furthermore, the first cover section 26, including the first outer fabric 30 and the first inner fabric 32, has a thickness of 2 mm to 5 mm combined, and the second cover section 28, including the second outer fabric 34 and the second inner fabric 36, has a thickness of 4 mm to 10 mm combined, and both are flexible, so when the head cover 12 is removed from the club head 14, the head cover 12 does not take up much space even when folded in half, and can be easily put into a pocket, which is advantageous in terms of increasing the practical value and commercial value of the head cover 12. Furthermore, the head cover 12 is light, weighing 15 to 50 g, so that it feels comfortable to put in a pocket, which is advantageous in terms of increasing the practical value and commercial value of the head cover 12. Furthermore, the thickness of the second cover section 28 is greater than that of the first cover section 26, which is advantageous in protecting the back surface 1404 of the club head 14, which is easily damaged during transportation or when returning the iron to the golf bag. The thickness of first cover section 26 may be greater than the thickness of second cover section 28, which is advantageous in terms of protecting face surface 1402. Furthermore, the head cover 12 conforms to the shape of the club head 14 when the club head 14 is inserted therein, and fits the club head 14, so there is no risk of the head cover 12 falling off during a round at the golf course.

[0025] In addition, the cover main body 18 is composed of a first cover section 26 that covers the face surface 1402 side of the club head 14, and a second cover section 28 that covers the back surface 1404 side of the club head 14, and the first cover section 26 and the second cover section 28 are joined on an imaginary extension plane of the face surface 1402 at the locations covering the face surface 1402 and the back surface 1404. The point where the first cover section 26 and the second cover section 28 are joined forms a joining ridge 38 that protrudes into the inside of the head cover 12 and extends along an imaginary extension plane of the face surface 1402. The joining ridge 38 includes a first ridge 42 that extends along the sole surface 1408 and is capable of contacting the end of the sole surface 1408 on the leading edge 1414 side where the face surface 1402 and the sole surface 1408 of the club head 14 intersect, as shown in FIG. 14, and a second ridge 44 that extends along the toe portion 1410 and is capable of contacting the end of the toe portion 1410 on the toe edge 1416 side where the face surface 1402 and the toe portion 1410 of the club head 14 intersect, as shown in FIG. 15. Therefore, when the club head 14 is inserted through the insertion / removal opening 22, the end of the sole surface 1408 on the leading edge 1414 side is guided by the first protrusion 42, and the end of the toe portion 1410 on the toe edge 1416 side comes into contact with the second protrusion 44, completing the insertion of the club head 14.

[0026] Therefore, when the head cover 12 is attached to the club head 14, the leading edge 1414 extends along the first protrusion portion 42, and the toe edge 1416 extends along the second protrusion portion 44, with the leading edge 1414 being positioned relative to the head cover 12 by the first protrusion portion 42 and the toe edge 1416 being positioned by the second protrusion portion 44. In addition, part of the extension direction of the first protrusion portion 42 is interrupted, and at this interrupted point, a straight edge portion 2602 of the first cover section 26 is located, extending continuously in a straight line along the edge portion of the first cover section 26 that constitutes the first protrusion portion 42, and the opening 24 is composed of the straight edge portion 2602 and a notch 2802 that exposes the numbers formed on the end of the second cover section 28 in an open state relative to the straight edge portion 2602, and one side of the opening 24 is positioned based on the extension direction of the first protrusion portion 42. Therefore, when the golf club head 14 is attached to the head cover 12, the leading edge 1414 and the toe edge 1416 are positioned relative to the head cover 12 by the first protrusion portion 42 and the second protrusion portion 44, and since one side of the opening 24 is positioned based on the extension direction of the first protrusion portion 42, the number representing the club head 14's number is always located within the opening 24 and is always visible. Therefore, during a round at a golf course or at a golf driving range, the golf club of the number to be used can be easily and surely taken out from the golf bag, damage to the club head 14 can be prevented, and the number of the club head 14 can be always seen from the opening 24 even after long-term use, which is advantageous in increasing the practical value and commercial value of the head cover 12.

[0027] As shown in FIG. 13, the edge 2802A (finger hook edge 2802A) of the cutout 2802 is formed by folding back a portion of the outer fabric (second outer fabric 34) of the second cover section 28 near the edge and folding it in half, and by folding back a portion of the inner fabric (second inner fabric 36) of the second cover section 28 near the edge and joining these folded portions. Therefore, the edge 2802A (finger hook edge 2802A) of the cutout 2802 is twice as thick as the second cover section 28 and is thicker than the thickness of the other second cover sections 28. Therefore, it is easy to hook the tip of the index finger on edge 2802A (finger hook edge 2802A) of cutout 2802, and since second cover part 28 is formed from a flexible fabric, it is easy to insert the tip of the index finger into the inside of opening 24 from edge 2802A (finger hook edge 2802A) of cutout 2802. Therefore, the head cover 12 can be moved easily and reliably by inserting the index finger inside the opening 24, hooking the pad of the first joint of the index finger on the edge 2802A (finger hook edge 2802A) of the notch 2802, and moving the index finger along the toe edge 1416 of the club head 14. This movement causes the blade portion 1406 on the heel side of the club head 14 to push open the club head attachment / detachment cover piece 20, allowing the head cover 12 to be easily removed from the club head 14. This is advantageous in that the club head 14 can be easily and reliably removed, and the practical value of the head cover 12 is significantly improved.

[0028] Furthermore, when the head cover 12 is attached to the club head 14, the first hosel portion covering piece 26B and the second hosel portion covering piece 28B cover the entire length of the hosel portion 14B and the portion of the shaft 16 that is connected to the hosel portion 14B and is close to the hosel portion 14B, and the club head attachment / detachment cover piece 20 covers the entire length of the hosel portion 14B. Therefore, damage to the hosel portion 14B can be prevented when taking out or putting in the golf club or when transporting the golf club, which is suitable for players who use expensive golf clubs. In addition, the attachment / detachment opening 22 is large because it is formed by a first gap S1 between the tip of the first hosel portion covering piece 26B and the tip of the second hosel portion covering piece 28B, and a third gap S3 between the edge of the first hosel portion covering piece 26B and the edge of the second hosel portion covering piece 28B, and since the cover piece 20 for attaching and removing the club head is stretchable, this is advantageous in making it easy to attach and remove the head cover 12, and is advantageous in increasing the practical value and commercial value of the head cover 12.

[0029] Furthermore, if a narrow decorative segment 40 is used and the folded portion of this decorative segment 40 is joined by clamping it between the portion of the first cover segment 26 near the edge that forms the joining protrusion 38 folded inward and the portion of the second cover segment 28 near the edge that is folded inward so that the folded portion 4002 with the rod 42 sandwiched between them is positioned outside the head cover 12, this is advantageous in enhancing the design of the head cover 12. Although the rod 42 can be omitted, using the rod 42 is more advantageous in terms of enhancing the design.

[0030] When playing a round at the golf course, a vinyl sheet is provided above the area where the golf bags are loaded onto the golf cart, and even if it is raining, the vinyl sheet covers the top of the golf bags, so there is no need to worry about rain getting in through the opening 24 and getting the club head 14 wet. For those who have purchased expensive golf clubs and are concerned about such situations, a detachable lid body 50 bearing a number indicating the club head 14 number may be provided separately from the head cover 12 that closes the opening 24, as shown in Figures 16(A) and (B). In this case, for example, if a female hook-and-loop fastener 52 is provided on the head cover 12 around the opening 24, and a male hook-and-loop fastener (not shown) is provided around the periphery of the back surface of the lid 50, and the lid 50 is removably attached via these hook-and-loop fasteners to close the opening 24, then on rainy days the head cover 12 can be used with the lid 50 closing the opening 24, which is advantageous in preventing the club head 14 from getting wet on rainy days. Of course, Velcro (registered trademark) or the like may be used instead of the hook-and-loop fastener.

[0031] It is clear that the present invention is not limited to the above-described embodiment, and is not limited to irons, but can also be applied to utility clubs (hybrid clubs) and fairway woods. [Explanation of symbols]
