本考案はミシンに関するものであり、更に詳しくはミシ
ンの補助ベッドをベッドに装着する手段に関するもので
ある。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sewing machine, and more particularly to a means for attaching an auxiliary bed of a sewing machine to a bed.
従来からベッドに補助ベッドが装着され、該補助ベッド
を回動させた時に該補助ベッドを静止させてボビンの交
換を容易にするための手段を具えたミシンは種々に提供
されているが、いずれも構造や操作が複雑であるという
不具合があった。Conventionally, various sewing machines have been provided in which an auxiliary bed is attached to the bed and a means is provided for making bobbin replacement easier by keeping the auxiliary bed stationary when the auxiliary bed is rotated. However, the structure and operation were complicated.
本考案の目的は、かかる不具合を除去したミシンを提供
することにあり、その要旨とするところは、ベッドと補
助ベッドとを平担部を有するピンを介して連結し、該平
担部は常時補助ベッドの回動方向に付勢するように構成
したことにある。An object of the present invention is to provide a sewing machine that eliminates such defects, and its gist is that a bed and an auxiliary bed are connected via a pin having a flat part, and that the flat part is always This is because the structure is configured to bias the auxiliary bed in the direction of rotation.
以下、本考案の一実施例を添付図面に基いて説明する。An embodiment of the present invention will be described below with reference to the accompanying drawings.
第１図ないし第３図に於て、ミシン１０のベッド１１は
、その左側部に筒状部１２を有している。In FIGS. 1 to 3, a bed 11 of a sewing machine 10 has a cylindrical portion 12 on its left side.
そして、該筒状部１２はアーム１３と同一方向に延在し
ている。The cylindrical portion 12 extends in the same direction as the arm 13.
該ベッド１１の左側部に於ては、補助ベッド１４が配設
されており、該ベッド１１と同一平面を形成するように
なっている。An auxiliary bed 14 is disposed on the left side of the bed 11 and forms the same plane as the bed 11.
該補助ベッド１４の下面の右側にはピン１５の一端が固
定されており、該ピン１５の他端は該筒状部１２の側板
１２ ａを貫通して該筒状部１２内に突入している。One end of a pin 15 is fixed to the right side of the lower surface of the auxiliary bed 14, and the other end of the pin 15 penetrates the side plate 12a of the cylindrical portion 12 and protrudes into the cylindrical portion 12. There is.
該ピン１５の外周には、２つの平担部１６゜１７が鈍角
をなして形成されており、該両平担部１６と１７の両側
部にはテーパ一部１８．１９と２０．２１（平担部１７
のテーパ一部２０．２１は、番号が示されていない。Two flat portions 16 and 17 are formed at an obtuse angle on the outer periphery of the pin 15, and tapered portions 18.19 and 20.21 ( Flat part 17
The taper portions 20, 21 of are not numbered.
）が形成されている。該筒状部１２内には、略逆り字型
のブラケット２２が配設されており、該ブラケット２２
は、コーナー２３に於て、前記筒状部１２の側板１２
ａに回動可能に枢支されている。) is formed. A substantially inverted-shaped bracket 22 is disposed within the cylindrical portion 12.
is the side plate 12 of the cylindrical portion 12 at the corner 23.
It is rotatably supported on a.
該ブラケット２２の一端部２４と該側板１２ ａに形成
された突起２５との間には引張りばね２ｂが配設されて
おり、該ブラケット２２の他端部２７は前記ピン１５の
平担部１６と係合している。A tension spring 2b is disposed between one end 24 of the bracket 22 and a protrusion 25 formed on the side plate 12a, and the other end 27 of the bracket 22 is connected to the flat part 16 of the pin 15. is engaged with.
尚、該ベッド１１には、該筒状部１２と同一方向かつ平
行に補助ベッド受は台２８が形成される。Incidentally, an auxiliary bed support stand 28 is formed on the bed 11 in the same direction and parallel to the cylindrical portion 12.
そして、該筒状部１２には該補助ベッド受は台２８に面
してカマカバー２９が設けられている。A hook cover 29 is provided on the cylindrical portion 12 so that the auxiliary bed support faces the base 28.
以上の構成に於ける作用効果を第４図をも併用して述べ
ると、補助ベッド１４を手で持って第２図Ａ方向に回動
させると、ブラケット２２の他端部２７はピン１５の平
担部１７と係合するようになる。The effects of the above configuration will be described with reference to FIG. 4. When the auxiliary bed 14 is held by hand and rotated in the direction A in FIG. It comes to engage with the flat part 17.
しかしてブラケット２２の他端部２７は引張りばね２６
の側きによ常時Ｂ方向に回動しようとする。Thus, the other end 27 of the bracket 22 has a tension spring 26
It always tries to rotate in direction B due to its side.
そして、補助ベッド１４から手を離したとき補助ベッド
１４はＡ′方向に回動しようとするが、その回動はブラ
ケット２２により阻止され、第４図に示すが如く補助ベ
ッド１４を静止させることができる。When the hand is released from the auxiliary bed 14, the auxiliary bed 14 tries to rotate in the direction A', but this rotation is prevented by the bracket 22, and the auxiliary bed 14 is kept stationary as shown in FIG. Can be done.
その結果、補助ベッド１４と補助ベッド受は台２８との
間の空間を大きく開放できるので、カマカバ２９をはず
してボビンの交換を極めて容易に行なうことができる。As a result, since the space between the auxiliary bed 14 and the pedestal 28 can be largely opened, the cover 29 can be removed to replace the bobbin very easily.
また、補助ベッド１４を第３図Ｃ方向に引張ると、補助
ベッド１４をベッド１１の筒状部１２から容易に分離す
ることができ、直ちに筒物縫１１の本勢をとることがで
きる。Further, when the auxiliary bed 14 is pulled in the direction C in FIG. 3, the auxiliary bed 14 can be easily separated from the cylindrical portion 12 of the bed 11, and the main action of the cylindrical material sewing 11 can be taken immediately.
以上述べたように、本考案は実用上多大な効果を奏する
。As described above, the present invention has great practical effects.
尚、本考の一実施例では、付勢手段として、ブラケット
２２と引張りばね２６を用いて説明したが゛、板ばねを
用いてもよいことは説明をするまでもなく明らかであろ
う。In the embodiment of the present invention, the bracket 22 and the tension spring 26 are used as the biasing means, but it is obvious that a leaf spring may also be used.
