続いて、第１実施形態に係るドアハンドル装置１の使用態様を説明する。
図１中の実線で示した右勝手状態のレバーハンドル３を中立位置Ｃから、図１中の仮想線で示したように、レバーハンドル３を把持してハンドル軸４廻りで一方へ回動させた場合には、回動部材５の作動部７はリターンばね６の一端部６ａに当接する。これにより、一端部６ａは回動部材５の作動部７によってレバーハンドル３の回動方向と同じ方向に回動されると共に、他端部６ｂは設定部材８のばね当たり部９Ｒに位置決めされている。 The notches 41 are provided at both ends in the longitudinal direction of the setting member 8 and at the center in the width direction, and are formed in a substantially semicircular shape along the peripheral wall of the screw receiver 20 b of the door washer 2. The notch 41 serves as a relief for the screw receiver 20b so that the screw receiver 20b does not hit the setting member 8 when the setting member 8 is attached to the door washer 2.
Then, the usage aspect of the door handle apparatus 1 which concerns on 1st Embodiment is demonstrated.
The lever handle 3 in the right-handed state shown by the solid line in FIG. 1 is gripped from the neutral position C and rotated to one side around the handle shaft 4 as shown by the phantom line in FIG. In this case, the actuating portion 7 of the rotating member 5 comes into contact with the one end portion 6 a of the return spring 6. As a result, the one end portion 6a is rotated in the same direction as the rotation direction of the lever handle 3 by the operating portion 7 of the rotation member 5, and the other end portion 6b is positioned at the spring contact portion 9R of the setting member 8. Yes.

したがって、リターンばね６における一端部６ａは、回動部材５の作動部７と共に他端部６ｂからハンドル軸４周方向に沿って離れていくため、レバーハンドル３の回動によってリターンばね６は収縮する。
レバーハンドル３から手を離すと、リターンばね６には一端部６ａが他端部６ｂに近づく方向に復元力が働き、この復元力を受けたレバーハンドル３は中立位置Ｃに戻る。
レバーハンドル３をハンドル軸４廻りで逆に他方へ回動させた場合には、回動部材５の作動部７は逆にリターンばね６の他端部６ｂに当接する。これにより、他端部６ｂは回動部材５の作動部７によってレバーハンドル３の回動方向と同じ方向に回動され、リターンばね６が収縮する。レバーハンドル３から手を離すと、リターンばね６の復元力によってレバーハンドル３は中立位置Ｃに戻る。 Therefore, one end portion 6a of the return spring 6 moves away from the other end portion 6b along the circumferential direction of the handle shaft 4 together with the operating portion 7 of the rotation member 5, and therefore the return spring 6 contracts by the rotation of the lever handle 3. To do.
When the hand is released from the lever handle 3, a restoring force acts on the return spring 6 in a direction in which the one end portion 6a approaches the other end portion 6b, and the lever handle 3 receiving the restoring force returns to the neutral position C.
When the lever handle 3 is rotated to the other side around the handle shaft 4, the operating portion 7 of the rotating member 5 abuts against the other end 6 b of the return spring 6. As a result, the other end 6 b is rotated in the same direction as the rotation direction of the lever handle 3 by the operating portion 7 of the rotation member 5, and the return spring 6 contracts. When the hand is released from the lever handle 3, the lever handle 3 returns to the neutral position C by the restoring force of the return spring 6.

なお、レバーハンドル３が左勝手であれば、リターンばね６の一端部６ａ又は他端部６ｂは設定部材８のばね当たり部９Ｌによって位置決めされる。
図１中の実線及び図２中の仮想線にて示されたレバーハンドル３が右勝手である状態から、図２中の実線で示されたレバーハンドル３が左勝手である状態へ切り換える場合には、まずドア座金２から設定部材８を外し、設定部材８における一方のばね当たり部９Ｒとリターンばね６の両端部６ａ、６ｂとの係止関係を解く。
このあと、正面視でハンドル軸４から右方に延びた状態のレバーハンドル３をハンドル軸４廻りに１８０°変位させて正面視でハンドル軸４から左方に延びた状態とすると、リターンばね６の両端部６ａ、６ｂは、ハンドル軸４廻りに１８０°変位し、設定部材８における他方のばね当たり部９Ｌと係止させることができる位置にくる。 If the lever handle 3 is left-handed, one end 6a or the other end 6b of the return spring 6 is positioned by the spring contact portion 9L of the setting member 8.
When the lever handle 3 indicated by the solid line in FIG. 1 and the phantom line in FIG. 2 is a right-handed state, the lever handle 3 indicated by the solid line in FIG. 2 is switched to a left-handed state. First, the setting member 8 is removed from the door washer 2, and the locking relationship between one spring contact portion 9R of the setting member 8 and both end portions 6a and 6b of the return spring 6 is released.
Thereafter, when the lever handle 3 extending rightward from the handle shaft 4 in the front view is displaced 180 ° around the handle shaft 4 to extend leftward from the handle shaft 4 in the front view, the return spring 6 Both end portions 6a and 6b are displaced by 180 ° around the handle shaft 4 and come to a position where they can be engaged with the other spring contact portion 9L of the setting member 8.

他方のばね当たり部９Ｌをリターンばね６の両端部６ａ、６ｂの間に入れながら、そのまま設定部材８をドア座金２に取り付けるだけで、設定部材８における他方のばね当たり部９Ｌとリターンばね６の両端部６ａ、６ｂとの係止関係が生じる。
よって、特別な操作や道具がなくとも、リターンばね６の両端部６ａ、６ｂに係止するばね当たり部９Ｌ、９Ｒを有した設定部材８を着脱するだけで、非常にスムースにレバーハンドル３の左右勝手を切り換えることができる。さらに、プレート状の設定部材８を使用しているため、簡単な構造でレバーハンドル３の左右勝手の切換が可能となり、十分な強度を持ったドアハンドル装置１となる。 By simply attaching the setting member 8 to the door washer 2 while putting the other spring contact portion 9L between the both end portions 6a and 6b of the return spring 6, the other spring contact portion 9L of the setting spring 8 and the return spring 6 A locking relationship with both end portions 6a and 6b occurs.
Therefore, even if there is no special operation or tool, the lever handle 3 can be moved very smoothly by simply attaching / detaching the setting member 8 having the spring contact portions 9L, 9R to be engaged with the both ends 6a, 6b of the return spring 6. You can switch between left and right. Furthermore, since the plate-shaped setting member 8 is used, the lever handle 3 can be switched between the left and right sides with a simple structure, and the door handle device 1 having sufficient strength can be obtained.

ドアハンドル装置１は、レバーハンドル３の回動をロックするロック機構を有していてもよい。
ドア座金２は、正面視で楕円形、矩形等であってもよい。 Other functions and effects are substantially the same as those of the first embodiment.
In addition, this invention is not limited to embodiment mentioned above. Each configuration of the door handle device 1 or the like, or the overall structure, shape, dimensions, and the like can be appropriately changed in accordance with the spirit of the present invention.
The door handle device 1 may have a lock mechanism that locks the rotation of the lever handle 3.
The door washer 2 may be oval or rectangular in front view.

設定部材８は、ドア座金２内において下側へ偏心して配置されているが、ドア座金２内において上側へ偏心して配置されていてもよい。
設定部材８として、長手方向から所定角度（±３０°、±４０°、±４５°、±６０°等）変位したストッパ部１１を設けたものを複数種類用意することで、他の部材を共通としながら、種類の異なる設定部材８を取り付けるだけで、レバーハンドル３を様々な回動範囲に設定できることとしてもよい。
ストッパ部１１を設定部材８に設けずに、ドア座金２に設けてもよい。 The setting member 8 is arranged eccentrically downward in the door washer 2, but may be arranged eccentrically upward in the door washer 2.
By preparing multiple types of setting members 8 with stopper portions 11 displaced from the longitudinal direction by a predetermined angle (± 30 °, ± 40 °, ± 45 °, ± 60 °, etc.), other members can be used in common. However, the lever handle 3 may be set to various rotation ranges simply by attaching different types of setting members 8.
The stopper 11 may be provided on the door washer 2 without being provided on the setting member 8.

ストッパ部１１を設けてレバーハンドル３の回動範囲を設定するかわりに、レバーハンドル３の回動にてリターンばね６は縮み且つ内径が狭まってドア座金２の支持部２１と当接することで、それ以上リターンばね６は収縮できなくなり、レバーハンドル３の所定範囲以上の回動を規制してもよい。   Instead of providing the stopper portion 11 and setting the rotation range of the lever handle 3, the return spring 6 is contracted and the inner diameter is narrowed by the rotation of the lever handle 3 and comes into contact with the support portion 21 of the door washer 2. The return spring 6 can no longer contract, and the lever handle 3 may be restricted from turning beyond a predetermined range.
