A pair of first contact portions 10g and 10g that come into contact with the bottom of the housing 5 are provided , and second contact portions 10h and 10h are provided on the lower end side of the fixing portions 10b and 10b, respectively.
次に、本発明に係るスライドヒンジ１の拡径手段１２、１３を各取付用ケース内８、９に組み付ける組付け手順について説明する。まず、各係止盤１４、１５をその底板部１４ａ、１５ａの突出片１４ｆ、１５ｆに設けた直線部１４ｈ、１５ｈを、各取付用ケース部８、９の収容凹部８ｇ、９ｇの平坦部８ｈ、９ｈの位置に合わせて当該収容凹部８ｇ、９ｇ内へ挿入させる。すると、底板部１４ａ、１５ａに設けたボス部１４ｃ、１５ｃが取付用ケース部８、９内に設けた軸受孔８ｅ、９ｅに嵌まり込んだ状態で左右いずれの方向にも回転することはなく装着固定される。次いで、各作動盤１６、１７を係止盤１４、１５の各係止片１４ｅ、１５ｅの中にその押圧部１６ａ、１７ａが各係止片１４ｅ、１５ｅの間に来るように、さらにストッパー片１６ｅ、１７ｅが第２ガイド孔１４ｇ、１５ｇ内へ挿入されるようにして挿入させると、そのボス部が係止盤１４、１５に設けた軸受穴１４ｂ、１５ｂに挿入されつつ収容される。次に、各キャップ１８、１９をその係止片１８ｂ、１９ｂを係止孔８ｂ、９ｂに係合させつつ、その軸受孔１８ａ、１９ａを工具装着部１６ｂ、１７ｂに合わせて下押しすると、係止凹部１８ｃ、１８ｃ・１９ｃ、１９ｃが係止片８ｃ、８ｃ・９ｃ、９ｃに係止された状態で取付用ケース部８、９へ装着される。これが、拡径手段１２、１３の組み付け手順である。この状態において、図１２（ａ）、（ｂ）に示したように、係止盤１４、１５の各爪部１４ｄ、１４ｄ、１４ｄ・１５ｄ、１５ｄ、１５ｄが、取付用ケース部８、９に設けた挿通孔８ａ、８ａ、８ａ・９ａ、９ａ、９ａから外側へ突出していないので、外観上すっきりとしたものになる上に、その取付時に連結用筐体５と取付用ケース部８、９を、実施例１のキャビネット２の扉体２ｂに設けた取付穴２ｃと連接穴２ｄ、２ｅへの挿入が容易となるという利点がある。また、取付後においてスライドヒンジ１の連結用筐体５を扉体２ｂから取り外す場合には、作動盤１６、１７を反時計方向へ回転させると、係止盤１４、１５の各爪部１４ｄ、１４ｄ、１４ｄ・１５ｄ、１５ｄ、１５ｄが自動的に取付用ケース部８、９の中へ各挿通孔８ａ、８ａ、８ａ・９ａ、９ａ、９ａを介して引っ込むので、取付用ケース部８、９を連結用筐体５と共に取付孔２ｃや連接穴２ｄ、２ｅより取り外すことが容易となる利点もある。
Next, an assembling procedure for assembling the diameter-expanding means 12 and 13 of the slide hinge 1 according to the present invention to the mounting cases 8 and 9 will be described. First, the straight portions 14h and 15h in which the locking plates 14 and 15 are provided on the protruding pieces 14f and 15f of the bottom plate portions 14a and 15a are provided with the accommodating recesses 8g and 9g of the mounting case portions 8 and 9 and the flat portions 8h. , 9h, and are inserted into the accommodating recesses 8g and 9g. Then, the boss portions 14c and 15c provided in the bottom plate portions 14a and 15a do not rotate in either the left or right direction while being fitted in the bearing holes 8e and 9e provided in the mounting case portions 8 and 9. It is mounted and fixed. Next, the stopper pieces are further placed so that the pressing portions 16a and 17a are placed between the locking pieces 14e and 15e of the locking plates 14 and 15 and the pressing portions 16a and 17a are placed between the locking pieces 14e and 15e. When the 16e and 17e are inserted into the second guide holes 14g and 15g, the boss portion is inserted and accommodated in the bearing holes 14b and 15b provided in the locking plates 14 and 15. Next, the caps 18 and 19 are locked by engaging the locking pieces 18b and 19b with the locking holes 8b and 9b and pushing down the bearing holes 18a and 19a in accordance with the tool mounting portions 16b and 17b. The recesses 18c, 18c, 19c, and 19c are mounted on the mounting case portions 8 and 9 in a state of being locked to the locking pieces 8c, 8c, 9c, and 9c. This is the procedure for assembling the diameter expanding means 12 and 13. In this state, as shown in FIGS. 12A and 12B, the claw portions 14d, 14d, 14d / 15d, 15d, and 15d of the locking plates 14 and 15 are attached to the mounting case portions 8 and 9. Since it does not protrude outward from the provided insertion holes 8a, 8a, 8a / 9a, 9a, 9a, the appearance is neat, and the connecting housing 5 and the mounting case portions 8 and 9 are attached at the time of mounting. Has an advantage that it can be easily inserted into the mounting holes 2c and the connecting holes 2d and 2e provided in the door body 2b of the cabinet 2 of the first embodiment. Further, when the connecting housing 5 of the slide hinge 1 is removed from the door body 2b after mounting, when the operating plates 16 and 17 are rotated counterclockwise, the claws 14d of the locking plates 14 and 15 Since 14d, 14d, 15d, 15d, and 15d are automatically retracted into the mounting case portions 8 and 9 through the insertion holes 8a, 8a, 8a, 9a, 9a, and 9a, the mounting case portions 8 and 9 are used. There is also an advantage that it can be easily removed from the mounting holes 2c and the connecting holes 2d and 2e together with the connecting housing 5.
