【産業上の利用分野】
カム凸起を備えた操作レバーと固定接点を備えたケースの間に、左右のばね板に各山形部を形成したU形接点ばね板を介在設置してなり、操作レバーを右若しくは左方向へ設定角度回転するとそのカム凸起がU形接点ばね片の右若しくは左ばね板の山形部に乗り上げて該ばね板を反曲しその接点をケースの右若しくは左の固定接点に圧接(スイッチON)するスイッチ作用を行う、2方向レバースイッチを提供する。
【0002】
【従来の課題】
近時、CD、PD、DVD、各種メモリーカード、ビデオカセット、テープカセット等の関連機器、プリンター、FAX等の紙処理機構、その他において、2方向(右←→左)からの外力で2方向均等にスイッチ開閉する作用を行うスイッチの必要性が極めて多くなっている。
【0003】
そこで、出願人は先に、特願平7−152695号(特許公開平8−329783号)、「2方向レバースイッチ」をもって、上記の使用目的において上記の作用を有効に行うスイッチ手段として、ばね付レバーに右または左方向(2方向)から外力が加わると、該ばね付レバーが枢軸を中心として右または左の接点(ばね片の先端部)が固定接点から離隔(スイッチOFF)するスイッチ作用を行うようにした、2方向レバースイッチを開発提供したものである。
【0004】
然るところ、上記先願発明の「2方向レバースイッチ」は、操作レバーを右若しくは左方向へ回転するとU形ばね片の接点がケースの右若しくは左の固定接点から離隔してスイッチOFFする所謂ノーマルクローズ型のスイッチであったが、それと反対に操作レバーを右若しくは左方向へ回転すると右若しくは左の可動接点がケース側の右若しくは左の固定接点に圧接してスイッチONする所謂ノーマルオープン型のスイッチの必要性が極めて多く、また、該方式のスイッチであって高頻度使用に耐久し、高精度で丈夫であり、その上極めて小形なスイッチの提供が強く要望されていることに鑑みて本発明スイッチを提供して、従来の課題を解決したものである。
ちなみに本発明実施例の寸法は20×15×6mmくらいである。
【0005】
【課題を解決する手段】
即ち本発明は、円盤の中心に中心軸を突出し、該円盤の背面の中心点を通る想定y軸線の左右対称位置に左、右カム凸起を凸設し、円盤上部の想定y軸線上にレバーを突出した操作レバーを、ケース上に、中心点を中心とし、そのレバーが中心点を通る想定y軸線上から左右方向へ設定角度往復回動自在に備えると共に、操作レバーの中心軸に掛け回した鋏形ばねの左右端をケース側に係合支持して、右若しくは左方向へ回動した操作レバーが鋏形ばねの復元弾力で中心線上に復元するように備え、
【0006】
ケース底板の中心点を通る想定y軸線上で中心点より上位の左右対称位置に固定接点を備え、その端子をケース外に突出し、上記想定y軸線上で中心点より下位の位置にあけたスリットの下方位置の底板背面にコモン固定接点を備えてその端子をケース外に突出し、
基部とその中心を通る想定y軸線の左右対称位置に形成した左右ばね板からなり、各左右ばね板の略中央部に山形部を突出し、基部の先端をコモン接点、左、右ばね板の各先端を可動接点として、U形接点ばね板を設け、
【0007】
ケース底板に一段高く形成した取付部上にU形接点ばね板を各想定y軸線を一致させて取り付け、該U形接点ばね板の基部を底板のスリットから背面側に挿入してそのコモン接点を底板背面のコモン固定接点と離隔相対若しくは接触すると共に左、右ばね片の各可動接点を底板の左、右固定接点と離隔相対して位置せしめ、
【0008】
上記ケースに取り付けたU形接点ばね板上に、操作レバーを、ケースと円盤の中心点及び想定y軸線を一致させて載置して、該操作レバーを中心点(中心軸)を中心として想定y軸線の左右方向に設定角度回動自在に設置すると共に、中心軸に鋏形ばねを掛け回してその左右先端をケース側に係合して、該鋏形ばねの弾力に抗して左若しくは左方向へ設定角度回動した操作レバーが該鋏形ばねの復元弾力で想定y軸線上に復元するように備えたものであり、
【0009】
操作レバーのレバーを右若しくは左方向へ設定角度回動すると、円盤の背面に凸設した右若しくは左カム凸起がU形接点ばね板の右若しくは左ばね板の山形部に乗り上げ、よって、右若しくは左ばね板が反曲してその接点がケースの右若しくは左固定接点に圧接(ON)すると共に、基部が反対方向に反曲してそのコモン接点がコモン固定接点に圧接(ON)して、右若しくは左回路がスイッチONするように備えたものである、2方向レバースイッチによって課題を解決したものである。
【0010】
【実施例】
次に、本発明の実施例を説明する。(図1〜図9)
円盤1の中心に中心軸2を突出し、該円盤1の背面の中心点を通る想定y軸線の左右対称位置に左、右カム凸起3、3を凸設し、円盤1上部の想定y軸線上にレバー4を突出した操作レバー5を、ケース6上に、中心点を中心とし、そのレバー4が中心点を通る想定y軸線上から左右方向へ設定角度往復回動自在に備えると共に、操作レバー5の中心軸2に掛け回した鋏形ばね7の左右端をケース6側に係合支持して、右若しくは左方向へ回動した操作レバー4が鋏形ばね7の復元弾力で想定y軸上に復元するように備え、
【0011】
ケース6の底枚6aの中心点を通る想定y軸線上で中心点より上位の左右対称位置に固定接点8、8を備え、その端子8a、8aをケース6外に突出し、上記想定y軸線上で中心点より下位の位置にあけたスリット9の下方位置の底板背面にコモン固定接点10を備えてその端子10aをケース6外に突出し、
【0012】
基部11とその中心を通る想定y軸線の左右対称位置に形成した左右ばね板12、12からなり、該左、右ばね板12、12の各中央部に山形部14を突出し、基部11の先端をコモン接点11a、左、右ばね板12、12の先端を可動接点12a、12aとして、U形接点ばね板13を設け、
【0013】
ケース6の底板6aに一段高く形成した取付部15上にU形接点ばね板13を各想定y軸線を一致させて取り付け、該U形接点ばね板13の基部11を底板6aのスリット9から背面側に挿入してそのコモン接点11aを底板6a背面のコモン固定接点10と離隔相対若しくは接触すると共に、左、右ばね板12、12の各可動接点12a、12aを底板6aの左右固定接点8、8と離隔相対して位置せしめ、
【0014】
上記ケース6に取り付けたU形接点ばね板13上に、操作レバー5を、ケース6と円盤1の中心点及び想定y軸線を一致させて載置して、該操作レバー5を中心点(中心軸)を中心として想定y軸線の左右方向に設定角度回動自在に設置すると共に、中心軸2に鋏形ばね7を掛け回してその左右先端をケース6側に係合して、該鋏形ばね7の弾力に抗して左若しくは左方向へ設定角度回動した操作レバー5が該鋏形ばね7の復元弾力で想定y軸線上に復元するように備えたものであり、
【0015】
操作レバー5のレバー4を右若しくは左方向へ設定角度回動すると、円盤の背面に凸出した右若しくは左カム凸起3がU形接点ばね板13の右若しくは左ばね板12の山形部14に乗り上げ、よって、右若しくは左ばね板12が反曲してその接点12aがケース6の右若しくは左固定接点8に圧接(ON)すると共に、基部11が反対方向に反曲してそのコモン接点11aがコモン固定接点10に圧接(ON)するように備えた、2方向レバースイッチである。
【0016】
【作用】
操作レバー5のレバー4を想定y軸線上から右若しくは左方向へ設定角度回転すると、該操作レバー5が中心軸2を中心とし鋏形ばね7の弾力に抗して設定角度回転し、よって、その円盤1の背面の右若しくは左のカム凸起3が回転してU形接点ばね板13の右若しくは左ばね板12の山形部14に乗り上げ、該山形部14を下降することにより右若しくは左ばね板12を下方反曲して、その先端の可動接点12aをケース6の底板6aの右若しくは左の固定接点8に圧接し、同時にスリット9から底板背面に挿入したU形接点ばね板13の基部11が取付部15を支点として上方へ反曲し、その先端のコモン接点11aがコモン固定接点10に圧接(予め接触していた場合はより強く、また離隔していた場合は新規に圧接)して、スイッチONの状態になる。
【0017】
上記の操作レバー5のレバー4を設定角度回転した状態で、レバー4を解放すると、操作レバー5は鋏形ばね7の弾性復元力で元の想定y軸線上位置に復帰し、よって、カム凸起3がU形接点ばね板13の山形部14から復帰下降し、反曲していた右または左ばね板12が復元反曲し可動接点12aが固定接点8から離隔上昇してスイッチOFFとなる。
この時、基部11のコモン接点11aとコモン固定接点10は接触したまま、若しくは離隔した状態となる。
【0018】
【効果】
ケースと操作レバーの間にU形接点ばね板を介在設置し、操作レバーの設定角度回転でそのカム凸起がU形接点ばね板の山形部に強制的に乗り上げてばね板を強力に反曲下降し、その先端の可動接点をケースの固定接点に圧設(スイッチON)し、また、操作レバーを解放すると鋏形ばねの復元弾力で瞬時に復元して可動接点と固定接点が離隔(スイッチOFF)するようにしたので、スイッチON、OFF作用が確実に行われると共に、特に可動接点がカム凸起による強い押圧力で固定接点に対し抉るように圧接されるため、接触状態が確実安定的でチャタリングなどが生じないと共に常時接点のクリーニング作用を発揮して汚れによる不良接触を無くし得る。
【0019】
また、U形接点ばね板の基部先端をコモン接点としてケース背面のコモン固定接点と予め接触して若しくは離隔相対に備え、上記操作レバーの回転によりU形接点ばね板の下方反曲による可動接点と固定接点の圧接が行われると同時に、U形接点ばね板の反転側先端であるコモン接点が反対に上方反曲してコモン固定接点に圧接するように備えたため、上記と同じくコモン接点とコモン固定接点の圧接(ON)が強固確実に行われると共に抉るように圧接することによるクリーニング作用も行われる効果がある。
【0020】
操作レバーとケースとU形接点ばね板、及び鋏形ばねの4点の部品を嵌着組立するだけで、上記の優れた特性を有する2方向レバースイッチを極めて簡単に設けることができ、また、各部品の構成が簡潔なため、スイッチ全体を極めて小形に設け得る。

[Industrial applications]
A U-shaped contact spring plate in which each chevron is formed on the left and right spring plates is interposed between an operation lever having a cam protrusion and a case having a fixed contact, and the operation lever is moved rightward or leftward. When the set angle is rotated, the protrusion of the cam rides on the angled portion of the right or left spring plate of the U-shaped contact spring piece, recurves the spring plate and presses the contact to the right or left fixed contact of the case (switch ON). There is provided a two-way lever switch that performs a switching operation.
[0002]
[Conventional issues]
Recently, in the related equipment such as CDs, PDs, DVDs, various memory cards, video cassettes and tape cassettes, printers, paper processing mechanisms such as faxes, etc., two directions (right ← → left) equalize in two directions. The necessity of a switch for opening and closing a switch has become extremely large.
[0003]
In view of this, the applicant has previously disclosed in Japanese Patent Application No. 7-152699 (Japanese Patent Application Laid-Open No. 8-329783) a "two-way lever switch" as a switch means for effectively performing the above-described operation for the above-mentioned purpose of use. When an external force is applied to the lever with the lever from the right or left direction (two directions), the spring-operated lever separates (switches off) the right or left contact (the tip of the spring piece) from the fixed contact about the pivot. And developed and provided a two-way lever switch.
[0004]
However, the so-called "two-way lever switch" of the prior application is a so-called "two-way lever switch" in which when the operating lever is rotated right or left, the contact of the U-shaped spring piece is separated from the right or left fixed contact of the case to switch off. It is a normally closed type switch, but on the contrary, when the operating lever is rotated to the right or left, the right or left movable contact is pressed against the right or left fixed contact on the case side to switch on, so-called normally open type. In view of the fact that there is a great need for switches of this type, and that there is a strong demand for providing a switch of this type that is durable for frequent use, highly accurate and durable, and also extremely small. A switch according to the present invention is provided to solve the conventional problem.
Incidentally, the size of the embodiment of the present invention is about 20 × 15 × 6 mm.
[0005]
[Means to solve the problem]
That is, the present invention projects the central axis at the center of the disk, and protrudes the left and right cam protrusions at the left-right symmetrical position of the assumed y-axis passing through the center point on the back of the disk, on the assumed y-axis at the top of the disk. An operating lever with a protruding lever is provided on the case so that it can reciprocate at a set angle from left to right from the assumed y-axis passing through the center point, centering on the center point, and hung on the center axis of the operating lever. The left and right ends of the rotated scissor-shaped spring are engaged and supported on the case side, and the operation lever rotated to the right or left is provided so as to be restored on the center line by the restoring elasticity of the scissor-shaped spring,
[0006]
A fixed contact is provided at a symmetric position above the center point on the assumed y-axis passing through the center point of the case bottom plate, and the terminal is projected outside the case, and a slit is provided at a position lower than the center point on the assumed y-axis. A common fixed contact is provided on the back of the bottom plate at the lower position of, and its terminal protrudes out of the case,
It consists of a left and right spring plate formed at the symmetrical position of the base part and the assumed y-axis passing through the center, and protrudes a chevron at the approximate center of each left and right spring plate. A U-shaped contact spring plate is provided with the tip as a movable contact,
[0007]
A U-shaped contact spring plate is mounted on the mounting portion formed one step higher on the case bottom plate so that each assumed y-axis coincides with each other, and the base of the U-shaped contact spring plate is inserted from the slit of the bottom plate to the back side to connect the common contact. The movable contacts of the left and right spring pieces are positioned opposite to and separated from the left and right fixed contacts of the bottom plate, respectively.
[0008]
An operation lever is placed on the U-shaped contact spring plate attached to the case so that the center point of the case and the disk and the assumed y-axis are aligned, and the operation lever is assumed to be centered on the center point (center axis). It is installed so as to be rotatable at a set angle in the left-right direction of the y-axis, and a scissor-shaped spring is wrapped around the central axis to engage the left and right ends of the case with the case side, and left or right against the elasticity of the scissor-shaped spring. The operation lever rotated to the left by the set angle is provided so as to be restored on the assumed y-axis by the restoration elasticity of the scissor-shaped spring,
[0009]
When the lever of the operation lever is turned to the right or left by a set angle, the right or left cam protrusion protruding from the back of the disk rides on the chevron of the right or left spring plate of the U-shaped contact spring plate, and Alternatively, the left spring plate is bent and the contact is pressed against the right or left fixed contact of the case (ON), while the base is bent in the opposite direction and the common contact is pressed against the common fixed contact (ON). , The right or left circuit is provided so as to switch on, and the problem is solved by a two-way lever switch.
[0010]
【Example】
Next, examples of the present invention will be described. (FIGS. 1 to 9)
The center axis 2 protrudes from the center of the disk 1, and left and right cam protrusions 3, 3 are projected at left and right symmetrical positions of an assumed y-axis line passing through a center point on the back surface of the disk 1. An operation lever 5 projecting the lever 4 on the line is provided on the case 6 such that the lever 4 can be reciprocated to a set angle in the left-right direction from the y-axis supposed to pass through the center point around the center point. The left and right ends of the scissor-shaped spring 7 hung around the center shaft 2 of the lever 5 are engaged and supported on the case 6 side, and the operating lever 4 rotated right or left is assumed by the restoring elasticity of the scissor-shaped spring 7. In preparation for restoring on the axis,
[0011]
On the assumed y-axis passing through the center point of the bottom plate 6a of the case 6, fixed contacts 8, 8 are provided at left and right symmetric positions higher than the center point, and the terminals 8a, 8a protrude out of the case 6 and are placed on the assumed y-axis. A common fixed contact 10 is provided on the back surface of the bottom plate at a position below the slit 9 opened at a position lower than the center point, and its terminal 10a projects outside the case 6,
[0012]
The left and right spring plates 12 and 12 are formed at left and right symmetrical positions with respect to an assumed y-axis passing through the center of the base 11. A U-shaped contact spring plate 13 with the common contact 11a as the movable contacts 12a and 12a at the tips of the left and right spring plates 12 and 12,
[0013]
A U-shaped contact spring plate 13 is mounted on a mounting portion 15 formed one step higher on the bottom plate 6a of the case 6 so that respective assumed y-axis lines coincide with each other. Side, and the common contact 11a is separated from or relative to the common fixed contact 10 on the back of the bottom plate 6a, and the movable contacts 12a, 12a of the left and right spring plates 12, 12 are fixed to the left and right fixed contacts 8, 8 and spaced apart from each other,
[0014]
The operation lever 5 is placed on the U-shaped contact spring plate 13 attached to the case 6 so that the center point of the case 6 and the center of the disk 1 coincide with the assumed y-axis. (Axis) about the assumed y-axis, and a scissor-shaped spring 7 is wrapped around the central axis 2 and its left and right ends are engaged with the case 6 side. The operation lever 5 rotated leftward or leftward by a set angle against the elasticity of the spring 7 is provided so as to be restored on the assumed y-axis by the elasticity of the scissors-shaped spring 7,
[0015]
When the lever 4 of the operation lever 5 is turned to the right or left by a set angle, the right or left cam protrusion 3 protruding from the back of the disk becomes the chevron 14 of the right or left spring plate 12 of the U-shaped contact spring plate 13. The right or left spring plate 12 is bent inward, and its contact 12a is pressed against (ON) the right or left fixed contact 8 of the case 6, and the base 11 is bent in the opposite direction and its common contact is bent. A two-way lever switch 11a is provided so as to be pressed (ON) to the common fixed contact 10.
[0016]
[Action]
When the lever 4 of the operation lever 5 is rotated to the right or left from the assumed y-axis by a set angle, the operation lever 5 rotates about the center axis 2 against the resilience of the scissor-shaped spring 7 by a set angle. The right or left cam projection 3 on the back surface of the disk 1 rotates and rides on the chevron 14 of the right or left spring plate 12 of the U-shaped contact spring plate 13, and descends the chevron 14 to move right or left. The spring plate 12 is bent downward and the movable contact 12a at the tip thereof is pressed against the right or left fixed contact 8 of the bottom plate 6a of the case 6, and at the same time, the U-shaped contact spring plate 13 inserted from the slit 9 into the back surface of the bottom plate. The base portion 11 is bent upward with the mounting portion 15 as a fulcrum, and the common contact 11a at the tip thereof is pressed against the common fixed contact 10 (stronger if previously contacted, and newly pressed if separated). Then switch A state of N.
[0017]
When the lever 4 is released while the lever 4 of the operation lever 5 is rotated by the set angle, the operation lever 5 returns to the original position on the assumed y-axis by the elastic restoring force of the scissor-shaped spring 7, and therefore, the cam protrusion is formed. The spring 3 returns and descends from the chevron 14 of the U-shaped contact spring plate 13, the right or left spring plate 12, which has been bent back, is restored and bent, and the movable contact 12 a is separated from the fixed contact 8 and rises to be turned off. .
At this time, the common contact 11a of the base 11 and the common fixed contact 10 are kept in contact or separated from each other.
[0018]
【effect】
A U-shaped contact spring plate is interposed between the case and the operating lever, and the cam projection forcibly rides on the angled portion of the U-shaped contact spring plate when the operating angle of the operating lever is rotated, and the spring plate is strongly bent. When the operating contact is released, the movable contact at the end of the movable contact is instantaneously restored by the restoring elasticity of the scissor-shaped spring, and the movable contact is separated from the fixed contact (switch). OFF), the switch ON and OFF actions are performed reliably, and the movable contact is pressed against the fixed contact with a strong pressing force due to the projection of the cam, so that the contact state is surely stable. Thus, chattering or the like does not occur, and a contact cleaning effect is always exerted to prevent a bad contact due to dirt.
[0019]
Also, the base end of the U-shaped contact spring plate is provided as a common contact in advance in contact with or separated from the common fixed contact on the back of the case, and the movable contact is formed by downward bending of the U-shaped contact spring plate by rotation of the operation lever. At the same time as the fixed contact is pressed, the common contact, which is the tip on the reverse side of the U-shaped contact spring plate, is bent upward and presses against the common fixed contact. There is an effect that the contact (ON) of the contact is firmly and reliably performed, and the cleaning action is also performed by pressing the contact so as to gouge.
[0020]
By simply fitting and assembling the four parts of the operating lever, the case, the U-shaped contact spring plate, and the scissor-shaped spring, a two-way lever switch having the above excellent characteristics can be provided extremely easily. Since the configuration of each part is simple, the entire switch can be provided in a very small size.
The drawings of the embodiments are shown about 5 times as large as the actual ones.

Operation of projecting a central axis at the center of the disk, projecting left and right cam protrusions at left and right symmetrical positions of an assumed y-axis passing through the center point on the back of the disk, and projecting a lever on the assumed y-axis at the top of the disk. A lever is provided on the case such that the lever is reciprocally rotatable about a center point and a set angle in the left-right direction from an assumed y-axis line passing through the center point.
The left and right ends of the scissor-shaped spring hung around the center axis of the operating lever are engaged with and supported by the case, so that the operating lever rotated to the right or left is restored to the center line by the restoring elasticity of the scissor-shaped spring. Prepare,
A fixed contact is provided at a symmetric position above the center point on the assumed y-axis passing through the center point of the case bottom plate, and the terminal is projected outside the case, and a slit is provided at a position lower than the center point on the assumed y-axis. A common fixed contact is provided on the back of the bottom plate at the lower position of, and its terminal protrudes out of the case,
It consists of a left and right spring plate formed at the symmetrical position of the base part and the assumed y-axis passing through the center, and protrudes a chevron at the approximate center of each left and right spring plate. A U-shaped contact spring plate is provided with the tip as a movable contact,
A U-shaped contact spring plate is mounted on the mounting portion formed one step higher on the case bottom plate so that each assumed y-axis coincides with each other, and the base of the U-shaped contact spring plate is inserted from the slit of the bottom plate to the back side to connect the common contact. The movable contacts of the left and right spring pieces are positioned opposite to and separated from the left and right fixed contacts of the bottom plate, respectively.
An operation lever is placed on the U-shaped contact spring plate attached to the case so that the center point of the case and the disk and the assumed y-axis are aligned, and the operation lever is assumed to be centered on the center point (center axis). It is installed so as to be rotatable at a set angle in the left-right direction of the y-axis, and a scissor-shaped spring is wrapped around the central axis to engage the left and right ends of the case with the case side, and left or right against the elasticity of the scissor-shaped spring. The operation lever rotated to the left by the set angle is provided so as to be restored on the assumed y-axis by the restoration elasticity of the scissor-shaped spring,
