Description:
TECHNICAL FIELD 
       [0001]    The present invention relates to an air cushion saddle, and more particularly, to an air cushion saddle for relieving a musculoskeletal system or dermalgia caused around the pelvis and allowing the circulation of the blood circulation to be smoothly perform when a user rides a bicycle for a long time. 
       BACKGROUND ART 
       [0002]    When a user rides a bicycle for a long time, the biggest pain is a saddle pain. 
         [0003]    A user feels a saddle pain when he or she uses a wide chair at normal times and changes to a narrow saddle. He or she has to go through some period of adjustment to some extent and experiences trial and error several times. 
         [0004]    Each user has a different pelvic width and the area that touches the saddle is also different. Each user is different depending on the shape of the pelvis or the shape of pelvic muscles. Accordingly, the saddle may be or may not be fit into a user just as it is perfect with a user. 
         [0005]    In addition, a shooting symptom may be generated if the blood is not circulated for a long time because a pressure point is located close to the saddle. 
         [0006]    In general, there are basically two types of saddle pains that occur when a user rides a bicycle. First, there is a pain generated because vibration from a road surface is transferred to the saddle, resulting in a shock on the hip. Second, there is a pain generated because the skin continues to be stimulated due to the friction between the saddle and the hip. 
         [0007]    In particular, in order to solve the saddle pain caused by the impact, in a conventional, a shock absorber was installed between the saddle and a bicycle frame. However, in this case, middle and higher class riders tend to be reluctant to use the shock absorber because the weight of the bicycle itself increases. 
         [0008]    In addition, each user has a different hipbone shape and a different sciatic size in the hip, whereas the shape of the saddle is fixed. Accordingly, it is costly to adjust the saddle to fit each rider one by one. 
         [0009]    In addition, although the size is correct, a conventional saddle cannot solve the problem of a pain upon riding for a long time because the saddle is made of a hard material and thus hinders a blood flow of the prostate gland or the lower part of the body.

         [0092]    In addition, the first fastening groove  1130  into which the lower end of the stiffening member  1600  is inserted and fastened are formed at the front and rear edges of the base plate  1100 . The Second fastening groove  1140  into which the first wing part  1211  and the second wing part  1224  are inserted are formed at the edges of both sides of the base plate  1100 . 
         [0093]    Meanwhile, the cushion member  1200  is mounted on the top of the base plate  1100  and is a portion that directly comes into contact with the body of a rider. 
         [0094]    Specifically, the cushion member  1200  is separated into a lower plate  1210  and an upper cover  1220 . 
         [0095]    The lower plate  1210  is formed of a plate made of NBR rubber and is formed to have a shape almost similar to a plane shape of the base plate  1100 . 
         [0096]    Furthermore, the second venthole  1230  communicating with the first venthole  1110  are formed in the lower plate  1210 . 
         [0097]    The second venthole  1230  are formed at the same position and in the same shape as the first venthole  1110 . 
         [0098]    Furthermore, the first wing part  1211  are protruded on both sides of the lower plate  1210 . 
         [0099]    The first wing parts  1211  are longly formed along the edges of both sides of the lower plate  1210 . Upon assembling, the first wing parts  1211  are overlapped with the second wing part  1224  of the upper cover  1220  to be described later and are inserted and fixed to the first fastening grooves  1130 . 
         [0100]    The lower plate  1210  is adhesively fixed to the top of the base plate  1100  by an adhesive. 
         [0101]    The upper cover  1220  is made of the same NBR rubber material as the lower plate  1210  and is mounted on the top of the lower plate  1210 . The upper cover  1220  has formed a bottom open and the inside upward recessed. 
         [0102]    The inside of the upper cover  1220  comes into contact with the lower plate  1210  to form a closed space  1221 . 
         [0103]    The upper cover  1220  may include a front portion  1220   a  which is disposed between the thighs of a rider and a rear portion  1220   b  which has a greater width than the front portion  1220   a  and on which the hips of a rider are disposed. 
         [0104]    As in the lower plate  1210 , the second venthole  1230  communicating with the first venthole  1110  are formed in the upper cover  1220 . 
         [0105]    The second venthole  1230  formed in the upper cover  1220  has the same shape as the second venthole  1230  formed in the lower plate  1210  and is disposed at the same position as the second venthole  1230 . 
         [0106]    Specifically, the second venthole  1230  formed in the upper cover  1220  may include a front venthole  1230   a  disposed in the front portion  1220   a  and a rear venthole  1230   b  disposed in the rear portion  1220   b.    
         [0107]    In this case, the front venthole  1230   a  is disposed at the center of the front portion  1220   a  in an oval long shape in the length direction, and one front venthole  1230   a  is disposed. 
         [0108]    The rear venthole  1230   b  has a circular shape, and two rear venthole  1230   b  are spaced apart and disposed in the rear portion  1220   b  in such a way as to be symmetrical left and right. 
         [0109]    In addition, a contact portion  1221  is formed to extend along the inner circumferential surface of the upper cover  1220  at the bottom of the second venthole  1230 . 
         [0110]    The contact portion  1221  is a portion engaged with the anchor member  1400  to be described later. 
         [0111]    In addition, a second bolt hole  1222  which is connected to the first bolt hole and in which the bolt member  1500  is fastened is formed in the upper cover  1220 . 
         [0112]    The second bolt hole  1222  is disposed close the front of the upper cover  1220  and downward protrudes in a cylindrical shape. 
         [0113]    In addition, a tab is formed in the second bolt hole  1222  so that the bolt member  1500  to be described later is fastened to the tab. 
         [0114]    The second bolt hole  1222  is vertically aligned with the first bolt hole  1120 . The bolt member  1500  to be described later is coupled up to the second bolt hole  1222  through the first bolt hole  1120 , thus closely fixing the base plate  1100  and the cushion member  1200 . 
         [0115]    Furthermore, a ventilation  1223  that is open between the rear venthole  1230   b  from the front venthole  1230   a  is formed in the upper cover  1220 . 
         [0116]    The ventilation  1223  allows the air to circulate from the front of the upper cover  1220  to the rear along with the front air bore  1230   a.    
         [0117]    There are effects in that sweating between thighs upon riding a bicycle for a long time is minimized and friction with the upper cover  1220  is reduced to reduce the occurrence of a pain because the ventilation  1223  is formed in the upper cover  1220  from the front venthole  1230   a  to the rear side as described above. 
         [0118]    In addition, the second wing part  1224  are formed on both sides of the bottom of the upper cover  1220 . 
         [0119]    The second wing part  1224  are formed in a thin film form and formed to lengthily protrude along the edges of both sides of the upper cover  1220 . 
         [0120]    When the cushion member  1200  is coupled to the base plate  1100 , the wing part are folded along with the first wing part  1211  and inserted and fixed to the first coupling groove  1130  in such a way as to be erected. 
         [0121]    As described above, the first wing part  1211  and the second wing part  1224  are formed in the cushion member  1200 . Accordingly, there is an effect in that the airtightness of the closed space  1221  formed between the lower plate  1210  and the upper cover  1220  is improved by increasing the contact area of the lower plate  1210  and the upper cover  1220  when the cushion member  1200  is mounted on the base plate  1100 . 
         [0122]    In addition, the closed space  1221  in which air is received is formed and the second venthole  1230  communicating with the first venthole  1110  are formed within the cushion member  1200 . Accordingly, there is an effect of further reducing the occurrence of a pain by distributing pressure upon contacting the body and circulating the air. 
         [0123]    In addition, there are effects in that fabrication is convenient due to a simplified configuration and the upper cover  1220  can be easily replaced and repaired when it is damaged because the cushion member  1200  is separated into the lower plate  1210  and the upper cover  1220 . 
         [0124]    Meanwhile, the valve member  1300  is formed of the same Dunlop style valve as the tube of a bicycle wheel. A pump for charging a bicycle tube is connected to the valve member  1300  to inject air into the closed space  1221  of the cushion member  1200 . When a nut at the end of the valve member  1300  is released, air within the cushion member  1200  can be discharged to the outside by a pressure difference. 
         [0125]    As described above, the valve member  1300  is provided in the cushion member  1200 . Accordingly, there is an effect in that a rider can freely implement desired ride comfort because the amount of air injected into the cushion member  1200  can be adjusted depending on the weight and body type of the rider. 
         [0126]    Meanwhile, the anchor member  1400  is for closely fixing the cushion member  1200  to the base plate  1100 . The anchor member  1400  is made of a synthetic resin material, and includes three members. The three members are respectively inserted into the first venthole  1110  and the second venthole  1230  communicating with each other and mounted thereon. 
         [0127]    More specifically, the anchor member  1400  may include a body portion  1410 , a support portion  1420  and hook portion  1430 . 
         [0128]    The body portion  1410  is a pipe form vertically penetrated and is inserted through the first venthole  1110  and the second venthole  1230  which communicate with each other. 
         [0129]    In this case, the anchor member  1400  mounted on the front venthole  1230   a  has an oval shape like the front venthole  1230   a,  and the anchor member  1400  mounted on the rear venthole  1230   b  has a circular shape. 
         [0130]    The support portion  1420  is formed to extend along an outer circumferential surface at the top of the body portion  1410  and comes into contact with the contact portion  1221  of the upper cover  1220 . 
         [0131]    In this case, fixing protrusion  1421  fixed to be embedded in the contact portion  1221  when they are closely attached to the contact portion  1221  are protruded from the support portion  1420 . 
         [0132]    The fixing protrusion  1421  become thinner in thickness downward and have pointed tips. 
         [0133]    As described above, the fixing protrusion  1421  are formed in the support portion  1420 . Accordingly, there is an effect of improving a coupling force because the fixing protrusion  1421  are deeply embedded in the support portion  1420  when the anchor member  1400  is mounted on the upper cover  1220 . 
         [0134]    The hook portion  1430  are formed at the bottom of the body portion  1410  and are hooked to the base plate  1100  so that the base plate  1100  and the cushion member  1200  are closely attached and fixed. 
         [0135]    Specifically, the hook portion  1430  has a shape protruded outward from the body portion  1410  as shown in  FIG. 3  and has both sides lengthily cut out up and down. Accordingly, the hook portion  1430  is elastically deformed inward when a specific force is applied thereto, and it returns to its original position when the force is removed. 
         [0136]    The hook portion  1430  are symmetrically disposed on both sides of the bottom of the body portion  1410 . 
         [0137]    As described above, the anchor member  1400  may include the body portion  1410 , the support portion  1420  and the hook portion  1430 . Accordingly, there are effects in that air is prevented from easily leaking and the assembly property is convenient because the base plate  1100  and the cushion member  1200  are closely attached each other, the perfect closed space  1221  is formed within the cushion member  1200 , and the airtightness of the inner circumferential surfaces of the first venthole  1110  and second venthole  1230  is improved. 
         [0138]    Meanwhile, the bolt member  1500  is the same as a common bolt and fastened to be inserted into the second bolt hole  1222  through the first bolt hole  1120 . 
         [0139]    There is an effect of further improving the coupling force of the base plate  1100  and the cushion member  1200  because the bolt member  1500  fastened to the first bolt hole  1120  and the second bolt hole  1222  is provided. 
         [0140]    Meanwhile, the stiffening member  1600  may include a first stiffening member  1610  enveloping the front of the cushion member  1200  and a second stiffening member  1620  enveloping the rear of the cushion member  1200 . 
         [0141]    Specifically, the first stiffening member  1610  is formed in the form of a thin shell that envelops the front of the cushion member  1200 . A step is formed at the lower end of the first stiffening member  1610  and is inserted and fixed to the first fastening groove  1130  formed at the front of the base plate  1100 . 
         [0142]    The second stiffening member  1620  is formed in the form of a thin shell that envelops the rear circumference of the cushion member  1200 . Likewise, a step is formed at the lower end of the second stiffening member  1620  and is inserted and fixed to the first fastening groove  1130  formed at the rear of the base plate  1100 . 
         [0143]    The first stiffening member  1610  and the second stiffening member  1620  are made of a synthetic resin material having higher strength than the material of the cushion member  1200 , thus preventing the cushion member  1200  from being damaged by pressure. 
         [0144]    In addition, the first stiffening member  1610  and the second stiffening member  1620  may be formed in various colors, so that the saddle can be designed in various designs. 
         [0145]    In the air cushion saddle having the above structure according to the second exemplary embodiment of the present invention, the closed space  1221  into which air is injected is formed in the cushion member  1200  made of a rubber material having high elasticity and tensile force. Accordingly, there are effects in that a saddle pain attributable to the frequent friction and shock of a road surface is solved and ride comfort is provided upon riding a bicycle. 
         [0146]    In particular, there are effects in that fabrication is convenient due to a simplified configuration and the upper cover  1220  can be easily replaced and repaired when it is damaged because the cushion member  1200  is separated into the lower plate  1210  and the upper cover  1220 . 
         [0147]    The present invention is not limited thereto and may be modified in various forms by those skilled in the art without departing from the spirit and scope of the following attached claims. Accordingly, such modification should be construed as belonging to the scope of the present invention.
