接下來，以下對本實施方式的帶扣10的卡合動作及使用方法進行說明。首先，對於該帶扣10的插頭12，簡單說明帶構件等的安裝方法。在插頭12的帶***部24設置著第一棒34、第二棒35，連結用的未圖示的帶構件是從插頭12的背面側***到帶插通孔24b，經過第二棒35的外周而從帶插通孔24a的表面側***到背面側，重疊於自身的帶構件而長度調節自如地被抽出。另一方面，安裝於插座14的未圖示的帶構件等無法調節地連結於一根連結棒44。Next, the engagement operation and the use method of the buckle 10 of the present embodiment will be described below. First, the mounting method of the belt member or the like will be briefly described for the plug 12 of the buckle 10. The first rod 34 and the second rod 35 are provided in the tape insertion portion 24 of the plug 12, and the belt member (not shown) for connection is inserted into the tape insertion hole 24b from the back side of the plug 12, and passes through the second rod 35. The outer circumference is inserted from the surface side of the insertion hole 24a to the back side, and is superposed on the belt member of the belt to be freely adjusted in length. On the other hand, a belt member or the like (not shown) attached to the socket 14 is unadjustably coupled to one of the connecting rods 44.
插頭12與插座14的卡合動作如圖2～圖4所示，使插頭12的脚部20與插座14的***口40a相向，將插頭12向插座14內壓入。當脚部20***到嵌合部40內時，薄壁部30***到嵌合部40的狹縫50，脚部20的卡合突起22分別抵接於收容空間52的靠近帶***部42的位置的引導面54。當在卡合突起22的外側面分別相接的狀態下進一步將插頭12壓入到插座14內時，隨著插頭12的***而利用引導面54的傾斜，脚部20以彼此靠近的方式發生彈性變形。然後，當脚部20的卡合突起22通過引導面54的端部時，以卡合突起22的卡止階部22a與插座14的被卡合部56面對面地卡合的方式，脚部20的彈性變形復原。由此，形成於插頭12的各脚部20的表背的卡合突起22分別與插座14的被卡合部56面對面地卡合，從而確實地將插頭12與插座14連結。然後，插頭12因形成插座14的***口40a的各上側壁部47與下側壁部48的端緣與肋部28的擋塊部31接觸而停止。As shown in FIGS. 2 to 4, the engaging operation of the plug 12 and the socket 14 is such that the leg portion 20 of the plug 12 faces the insertion opening 40a of the socket 14, and the plug 12 is pushed into the socket 14. When the leg portion 20 is inserted into the fitting portion 40, the thin portion 30 is inserted into the slit 50 of the fitting portion 40, and the engaging projections 22 of the leg portion 20 abut against the tape insertion portion 42 of the receiving space 52, respectively. Guide surface 54 of the position. When the plug 12 is further pressed into the socket 14 in a state where the outer sides of the engaging projections 22 are respectively brought into contact with each other, the inclination of the guiding surface 54 is performed with the insertion of the plug 12, and the leg portions 20 are brought closer to each other. Elastic deformation. Then, when the engaging projection 22 of the leg portion 20 passes the end portion of the guiding surface 54, the leg portion 20 is engaged with the engaging portion portion 22a of the engaging projection 22 and the engaged portion 56 of the socket 14 face-to-face. The elastic deformation is restored. Thereby, the engagement protrusions 22 formed on the front and back of each leg portion 20 of the plug 12 are engaged with the engaged portion 56 of the socket 14 so as to face the plug 14 and the socket 14 reliably. Then, the plug 12 is stopped by the end edges of the upper side wall portion 47 and the lower side wall portion 48 forming the insertion opening 40a of the socket 14 coming into contact with the stopper portion 31 of the rib portion 28.
爲了解除插頭12與插座14的連結，從外側按壓一對操作部26，使插頭12的卡合突起22彈性變形到不與插座14的被卡合部56面對面的位置。如果在該狀態下，使插頭12與插座14向彼此離開的方向稍微地相對移動，則離開卡合突起22與被卡合部56的面對面位置。由此，容易地解除卡合。In order to release the connection between the plug 12 and the socket 14, the pair of operation portions 26 are pressed from the outside to elastically deform the engagement projection 22 of the plug 12 to a position that does not face the engaged portion 56 of the socket 14. If the plug 12 and the socket 14 are slightly moved in the direction away from each other in this state, the face-to-face position of the engaging projection 22 and the engaged portion 56 is separated. Thereby, the engagement is easily released.
而且，本實施方式的帶扣10如圖12（a）、圖12（b）所示，在將插頭12相對於前後方向傾斜地***到插座14的情况下，也可將脚部20的一薄壁部30***到一狹縫50，並且卡合突起22的角部***座14的引導面54引導，當進一步壓入時，插頭12的肋部28的引導部32與插座14的上側壁部47與下側壁部48的端部接觸而無法***到狹縫50，對插頭12的朝向插座14的***方向進行引導。進而，此時利用狹縫50的寬度h與插頭12的薄壁部30的厚度t及肋部28的寬度H的所述關係，而防止一脚部20的薄壁部30以外的部分嵌合於插座14的狹縫50。Further, as shown in FIGS. 12(a) and 12(b), the buckle 10 of the present embodiment can also be used to insert the plug 12 into the socket 14 obliquely with respect to the front-rear direction. The wall portion 30 is inserted into a slit 50, and the corner portion of the engaging projection 22 is guided by the guiding surface 54 of the socket 14, and when further pressed in, the guiding portion 32 of the rib 28 of the plug 12 and the upper side wall portion of the socket 14 47 is in contact with the end of the lower side wall portion 48 and cannot be inserted into the slit 50, and guides the insertion direction of the plug 12 toward the socket 14. Further, at this time, the relationship between the width h of the slit 50 and the thickness t of the thin portion 30 of the plug 12 and the width H of the rib 28 is prevented, and the portion other than the thin portion 30 of the leg portion 20 is prevented from being fitted. In the slit 50 of the socket 14.
然後，當進一步將插頭12壓入到插座14內時，如圖13（a）、圖13（b）所示，另一脚部20的前端部20a及卡合突起22與插座14的引導面54接觸，而將插頭12向***方向引導。由此，插頭12被順暢地引導到插座14的收容空間52內。通過進一步將插頭12向插座14內壓入，而如所述那樣卡合突起22與被卡合部56卡合，從而將插頭12與插座14連結。Then, when the plug 12 is further pressed into the socket 14, as shown in FIGS. 13(a) and 13(b), the front end portion 20a of the other leg portion 20 and the engaging projection 22 and the guiding surface of the socket 14 are formed. 54 contacts, and the plug 12 is guided in the insertion direction. Thereby, the plug 12 is smoothly guided into the accommodating space 52 of the socket 14. By further pressing the plug 12 into the socket 14, the engagement projection 22 is engaged with the engaged portion 56 as described above, thereby connecting the plug 12 to the socket 14.
根據本實施方式的帶扣10，因形成於插座14的狹縫50與插頭12的脚部20的各部分的尺寸爲所述關係，所以即便在將插頭12相對於插座14而傾斜***的情况下，也不會出現如下情况：插頭12的一部分與插座14抵接，而無法進一步進行***動作，或脚部20的一部分進一步嵌合於狹縫50而被固定從而無法操作。插頭12通過進行***操作，而***座14的引導面54引導，並且插座14的一部分抵接於插頭12的引導部32，以成爲適當的***位置關係的方式一邊限制插頭12的移動一邊進行引導，插頭12的擋塊部31抵接於插座14的***口40a側端部而停止，卡合確實完成而進行連結。According to the buckle 10 of the present embodiment, since the size of each portion of the slit 50 formed in the socket 14 and the leg portion 20 of the plug 12 is in the above relationship, even when the plug 12 is obliquely inserted with respect to the socket 14 Further, there is no case where a part of the plug 12 abuts against the socket 14, and the insertion operation cannot be further performed, or a part of the leg portion 20 is further fitted to the slit 50 to be fixed and cannot be operated. The plug 12 is guided by the guide surface 54 of the socket 14 by the insertion operation, and a part of the socket 14 abuts against the guide portion 32 of the plug 12, and guides the movement of the plug 12 while being appropriately inserted into the positional relationship. The stopper portion 31 of the plug 12 abuts against the end portion of the socket 14 at the insertion port 40a side, and the engagement is completed, and the engagement is completed.
此外，插頭12的一對脚部20在其前端部20a的附近，利用U字狀的橋接部36而連結，因而向插座14***時的彈性變形容易，並且能够維持一定的强度。而且，未設置將一對脚部20的基端部20b連結的連結用的棒，而在帶***部24僅形成著第一棒34、第二棒35這兩根棒，因而能够形成抑制插頭12的前後方向尺寸且脚部20容易彎曲的結構。Further, since the pair of leg portions 20 of the plug 12 are connected by the U-shaped bridge portion 36 in the vicinity of the distal end portion 20a, elastic deformation at the time of insertion into the socket 14 is easy, and a constant strength can be maintained. Further, the connecting rod for connecting the proximal end portions 20b of the pair of leg portions 20 is not provided, and only the two rods of the first rod 34 and the second rod 35 are formed in the belt insertion portion 24, so that the plug can be formed. A structure in which the front and rear direction of the 12 is small and the leg portion 20 is easily bent.
另外，本發明的帶扣不限定於所述各實施方式，卡合突起22也可突出地設置在脚部20的表背的其中一面。而且，肋部28也可僅從表背的卡合突起22的一方伸展。在肋部28僅從表背方向的表面側的卡合突起22伸展的情况下，當將插頭12相對於前後方向傾斜***到插座14時，肋部28的引導部32與插座14的上側壁部47的端部接觸，從而無法***到狹縫50。而且，脚部20或收容空間52的形狀能够適當設定，只要脚部20的薄壁部30與肋部28及狹縫50的關係滿足所述條件即可。進而，插頭12或插座14的形狀也能够適當設定，視需要設置橋接部36即可，也能够適當設定帶***部24、帶***部42的形狀。Further, the buckle of the present invention is not limited to the above embodiments, and the engaging projection 22 may be provided to protrude from one of the front and back of the leg portion 20. Further, the ribs 28 may extend only from one of the engaging projections 22 of the front and back. In the case where the rib 28 extends only from the engaging protrusion 22 on the surface side in the front and rear directions, when the plug 12 is obliquely inserted into the socket 14 with respect to the front-rear direction, the guide portion 32 of the rib 28 and the upper side wall of the socket 14 The end of the portion 47 is in contact so that it cannot be inserted into the slit 50. Further, the shape of the leg portion 20 or the accommodating space 52 can be appropriately set as long as the relationship between the thin portion 30 of the leg portion 20 and the rib portion 28 and the slit 50 satisfies the above conditions. Further, the shape of the plug 12 or the socket 14 can be appropriately set, and the bridge portion 36 can be provided as needed, and the shape of the tape insertion portion 24 and the tape insertion portion 42 can be appropriately set.
