CROSS REFERENCE TO RELATED APPLICATIONS 
     This application is a national stage application of International Patent Application No. PCT/KR2012/006380, entitled “Ring for Enhanced Male Functions,” filed on Aug. 10, 2012, which claims priority to Korean Application No. 10-2011-0079865, filed on Aug. 10, 2011, the entire contents of which are incorporated herein by reference in their entirety. 
     TECHNICAL FIELD 
     The present invention relates to a ring for enhancing male functions and, more particularly, to a ring for enhancing male functions which can rapidly fasten and release ring segment members, strengthen erection while preventing separation of the ring, and prolong a sexual act by preventing premature ejaculation. 
     BACKGROUND 
     In general, erection of a penis is brought about by collective interaction of components of the endocrine system including nerves, blood vessels, the testes, and pituitary gland hormones, and the penis has a special structure to react to this process. The penis is formed of a cavernous body tissue, such as a sponge, including a number of blood vessels. When sexual stimuli including visual, aural, and tactile stimuli are applied, the blood vessels in the penis expand, a large amount of blood flows into the penis, and then the penis expands by blood pressure to become erect. Recently, due to complexities of social environments and stress from heavy workloads, however, a number of men suffer from erectile dysfunction and premature ejaculation preventing a normal sex life. 
     A background technique of the present invention is disclosed in Korean Patent Publication No. 2002-0043418 (published on Jun. 10, 2002 and entitled “Male function enhancement Ring”). 
     Since most male function enhancement rings sold in the market do not have an opening/closing device, a user must wait until erection subsides to remove the ring, or even when there is an opening/closing device, it is very difficult to open the ring. Accordingly, it is difficult to open the ring during full erection or a user must suspend a sexual act and wait until the erection subsides to open the ring. In addition, the opening/closing device of a typical male function enhancement ring is often unintentionally opened, causing user discomfort. Further, the typical male function enhancement ring has a limit in that when the penis becomes flaccid after the ring is fitted into the penis, the ring is likely to be lost due to separation from the penis. 
     Therefore, there is a need to solve such problems in the art. 
     SUMMARY 
     The present invention has been made to solve such problems in the art, and an aspect of the present invention is to provide a ring for enhancing male functions, which can rapidly fasten and release ring segment members and enables erection to be strengthened and prolonged for a long period of time by constricting the penis in stages even when the penis is not fully erect.

     Referring to  FIGS. 1 to 7 , a ring  1  for enhancing male functions according to one embodiment of the present invention includes a first ring segment member  10 , a second ring segment member  20 , and a fastening member  30 . The ring  1  has a ring shape and is divided into the first and second ring segment members  10 ,  20 . 
     The first ring segment member  10  forms one part (a left part in  FIG. 1 ) of the ring  1 , and the second ring segment member  20  forms the other part (a right part in  FIG. 1 ) of the ring  1 . 
     The fastening member  30  is provided to the second ring segment member  20  to be removably fastened to the first ring segment member  10 . When the fastening member  30  is fastened to the first ring segment member  10 , the first and second ring segment members  10 ,  20  form a ring shape. 
     One end  10   a  of the first ring segment member  10  is hingedly coupled to one end  20   a  of the second ring segment member  20 . Thus, the first and second ring segment members  10 ,  20  are coupled to each other to be rotated about a hinge h 1 . 
     The first segmented ring portion  10  has a recess  11  formed at the other end  10   b  thereof. The recess  11  is formed on an outer circumferential surface of the first ring segment member  10 . According to the present embodiment, the recess  11  is closed at both sides and at a lower side thereof, and is open at an upper side thereof to be formed in a ␣ shape. 
     The lower side of the recess  11  is closed. Accordingly, the penis cannot press the fastening member  30  even when the penis becomes erect with the ring  1  worn on the penis, thereby preventing the fastening member  30  from being unintentionally separated from the first ring segment member  10 . 
     Latch rods  12  latched to latch protrusions  32  described below are arranged in the recess  11 . The latch rods  12  are formed in a shape of a cylindrical column connecting the sidewalls of the recess  11  facing each other and are arranged to be separated from each other. 
     The one end  20   a  of the second ring segment member  20  is coupled to the first ring segment member  10 , and the other end of  20   b  of the second ring segment member  20  is hingedly coupled to one end  30   a  of the fastening member  30 . Thus, the fastening member  30  is provided to be rotated about a hinge h 2  relative to the second ring segment member  20 . 
     When the fastening member  30  is coupled to the other end  10   b  of the first ring segment member  10  while rotating about the hinge h 2  (see  FIG. 7 ) in a state in which the other end  10   b  of the first ring segment member  10  and the other end  20   b  of the second ring segment member  20  contact each other (see  FIG. 6 ), the first and second ring segment members  10 ,  20  form a ring shape. 
     The fastening member  30  includes a fastening plate  31  and the latch protrusions  32 . The fastening plate  31  is coupled to the other end  20   b  of the second ring segment member  20  through the hinge h 2 . An outer surface of the fastening plate  31  has the same smooth surface as the first and second ring segment members  10 ,  20 . 
     The latch protrusions  32  protrude from an inner surface of the fastening plate  31  and are latched to the latch rods  12 . According to the present embodiment, the latch rods  12  are formed in the shape of a cylindrical column, whereby the latch protrusions  32  contacting the latch rods  12  have a curved shape. 
     A plurality of latch protrusions  32  is arranged separated from each other. The plural latch protrusions  32  are latched to the latch rods  12  while being individually inserted into spaces defined between adjacent latch rods  12 . 
     The fastening member  30  and the first ring segment member  10  are fastened at a plurality of locations through the plurality of latch protrusions  32  and latch rods  12 . Accordingly, when the penis becomes erect while the ring  1  is worn on the penis, or external force is applied to the ring  1 , the fastening member  30  is prevented from being unintentionally separated from the first ring segment member  10 . As described above, according to the present embodiment, the fastening member  30  is separated from the first ring segment member  10  only when the latch protrusions  32  and the latch rods  12  are all released at a plurality of locations, thereby improving coupling strength between the fastening member  30  and the first ring segment member  10 . 
     When the latch protrusions  32  are latched to the latch rods  12 , the fastening plate  31  covers the recess  11  such that the recess  11  is not exposed to the outside. 
     According to the present embodiment, since the recess  11  is formed on the outer circumferential surface of the first ring segment member  10 , the fastening plate  31  that rotates about the hinge h 2  covers the recess  11  from above the recess  11 . Thus, the fastening plate  31  may prevent foreign substances from being introduced into the recess  11 . 
     A guide inclined surface  13  is formed on the outer circumferential surface of the first ring segment member  10 . The guide inclined surface  13  is formed on a portion of the outer circumferential surface of the first ring segment member  10  adjoining the recess  11  and guides a user&#39;s finger nail to the other end  30   b  of the fastening member  30 . 
     When separating the fastening member  30  from the first ring segment member  10 , a user separate the other end  30   b  of the fastening member  30  from the other end  10   b  of the first ring segment member  10  such that the latch protrusions  32  and the latch rods  12  are released. 
     The guide inclined surface  13  slopes to the recess  11  to allow a thumbnail of a user&#39;s right hand to easily reach the other end  30   b  of the fastening member  30 . When the nail of the user is attached to the other end  30   b  of the fastening member  30 , the user lifts the other end  30   b  of the fastening member  30  using the fingernail. When the other end  30   b  of the fastening member  30  is separated from the first ring segment member  10 , the fastening member  30  rotates about the hinge h 2  in the clockwise direction (see  FIG. 6 ). 
     When the fastening member  30  and the first ring segment member  10  are released as described above, the user can easily remove the ring  1  from the penis. 
     The first ring segment member  10  is provided with a location checking portion  14  on the outer circumferential surface thereof. The location checking portion  14  is disposed close to the guide inclined surface  13 . A user may rapidly recognize the other end  30   b  of the fastening member  30  through the location checking portion  14 . 
     Since a user can remove the penis confined by the first and second ring segment members  10 ,  20  from the ring by separating the other end  30   b  of the fastening member  30  from the first ring segment member  10 , it is very important to rapidly recognize the location of the other end  30   b  of the fastening member  30  in various emergency situations. 
     The location checking portion  14  is formed of a different material or color than that of the first ring segment member  10 . According to the present embodiment, the first ring segment member  10  is formed of silver and thus the location checking portion  14  may be formed of cubic zirconia or plastic having the feeling of a material completely different from that of the first ring segment member  10 . 
     Further, the location checking portion  14  may be formed in a red or blue color different from the inherent color of silver. As the location checking portion  14  is contrasted with the first ring segment member  10 , a user can more rapidly discover the location of the other end  30   b  of the fastening member  30  through the location checking portion  14 . 
     When the fastening member  30  is coupled to the first ring segment member  10 , the other end  30   b  of the fastening member  30  is located at a central portion of the ring formed by the first and second ring segment members  10 ,  20 . 
     When the fastening member  30  is coupled to the other end of the first ring segment member  10  such that the first and second ring segment members  10 ,  20  form the ring shape, the first and second ring segment members  10 ,  20  are mutually asymmetrically formed. 
     The hinge h 1  is located at a lower central portion of the ring formed by the first and second ring segment members  10 ,  20 , and the other end  30   b  of the fastening member  30  is located at an upper central portion of the ring shape formed by the first and second ring segment members  10 ,  20 . In other words, a straight line C connecting the hinge h 1  and the other end  30   b  of the fastening member  30  forms a centerline of the ring shape formed by the first and second ring segment members  10 ,  20 , namely, the ring  1 . 
     Since the other end  30   b  of the fastening member  30  is not biased to one side of the ring  1  and is disposed at the upper central portion of the ring, a user may easily separate the other end  30   b  of the fastening member  30  from the first ring segment member  10  with weak force. 
     Specifically, when the other end  30   b  of the fastening member  30  is located at the upper central portion as in the present embodiment, the fastening member  30  can be easily separated from the first ring segment member  10  by using the thumbnail of the right hand. However, when the other end  30   b  of the fastening member  30  is biased to one side such as a left or right side instead of the central portion, there is difficulty separating the fastening member  30  from the first ring segment member  10  using the thumbnail of the right hand. That is, separation of the fastening member  30  using the thumbnail of the left hand entails awkwardness of the nail direction, and separation of the fastening member  30  using the fingernail of the left hand index finger is not performed with ease since force of the index finger is weak and the fingernail is also weak. Accordingly, separation of the fastening member  30  can be most easily performed when the other end  30   b  of the fastening member  30  is located at the upper central portion of the ring. 
     First bosses  16  protrude inward from an inner circumferential surface of the first ring segment member  10 . In the present embodiment, the first bosses  16  protrude inward by about 2 mm to 3 mm from the inner circumferential surface. A plurality of first bosses  16  is formed on the inner circumferential surface of the first ring segment member  10  and a first groove  17  is formed between adjacent first bosses  16 . 
     The first boss  16  and the first groove  17  adjoin each other on the inner circumferential surface of the first ring segment member  10  to form a wave shape. 
     Second bosses  26  protrude inward from an inner circumferential surface of the second ring segment member  20 . In the present embodiment, the second bosses  26  protrude inward by about 2 mm to 3 mm from the inner circumferential surface. A plurality of second bosses  26  is formed on the inner circumferential surface of the second ring segment member  20  and a second groove  27  is formed between adjacent second bosses  26 . 
     The second boss  16  and the second groove  17  adjoin each other on the inner circumferential surface of the second ring segment member  20  to form a wave shape. 
     While the first and second ring segment members  10 ,  20  are fitted with the penis, the fastening member  30  is coupled to the first ring segment member  10 , as shown in  FIG. 7 . 
     As the first bosses  16  protrude from the inner circumferential surface of the first ring segment member  10  and the second bosses  26  protrude from the inner circumferential surface of the second ring segment member  20 , the penis contacts the first and second bosses  16  and  26  even in a flaccid state. Thus, the ring  1  does not separate from the penis even when the penis is completely flaccid. This means that the ring  1  does not separate from the penis even in a situation, such as walking, in which impact is not applied, and thus, the ring  1  can be previously prevented from being lost when worn on the penis. 
     The penis is stimulated by contact with the first and second bosses  16  and  26 , and is thus more likely to become erect as compared with when not stimulated. 
     As erection progresses, the penis is expanded toward the first and second grooves  17 ,  27 , whereby the thickness of the penis is further increased. Thereafter, pressure on the cavernous body of the penis increases, thereby strengthening erection, so that erection of the penis is much larger and stronger as compared with when the ring  1  is not used. Further, even when erection is maintained for a long period of time, the penis will not become flaccid. These effects can be more potently realized when the ring is continuously worn even at normal times in order to increase erection strength. 
     A highest protruding point M where the first boss  16  most highly protrudes inward is biased from a center to a rear end A of a cross section of the first boss  16 . With reference to  FIG. 2 , the highest protruding point M of the first boss  16  is located closer to the rear end A than a front end B. 
     For the first boss  16 , a slope from the rear end A to the highest protruding point M is greater than a slope from the front end B to the highest protruding point M. This prevents the ring  1  worn on the penis from being separated from the penis unless intended by a user. 
     The ring  1  for enhancing male functions is fitted with the penis such that the rear end A thereof faces towards the base of the penis and the front end B orients towards the glans. 
     Since the slope from the front end B to the highest protruding point M is relatively moderate in the first boss  16 , the ring  1  can be easily fitted with the penis towards the root of the penis. On the other hand, since the slope from the rear end A to the highest protruding point M is relatively steep in the first boss  16 , it is difficult for the ring  1  to move towards the glans. Accordingly, the ring  1  moves toward the glans to be prevented from separating from the penis. 
     In the present embodiment, the inner surface of the ring  1  is formed to be symmetric with respect to the centerline C. Accordingly, like the first boss  16 , a highest protruding point where the second boss  26  most highly protrudes inward is biased from a center to a rear end of a cross section of the second boss  26 . The highest protruding point of the second boss  26  is located closer to the rear end than a front end. 
     For the second boss  26 , a slope from the rear end to the highest protruding point is greater than a slope from the front end to the highest protruding point. This prevents the ring  1  worn on the penis from being separated from the penis unless intended by a user. 
     Since the slope from the front end to the highest protruding point is relatively moderate in the second boss  26 , the ring  1  is easily fitted with the penis towards the base of the penis. On the other hand, since the slope from the rear end to the highest protruding point is relatively steep in the second boss  26 , it is difficult for the ring  1  to move towards the glans. Accordingly, the ring  1  moves toward the glans to be prevented from separation from the penis. 
     A smooth surface portion P is formed on the inner surface of the ring  1  on which the first bosses  16 , the first grooves  17 , the second boss  26 , and the second grooves  27  are formed.
