Description

本発明は、ミラー角度調整構造に関する。   The present invention relates to a mirror angle adjustment structure.

従来、ガレージミラーや店内防犯ミラー等のミラー角度調整構造は、鏡体とその鏡体を鏡背面側から保持する支持基盤とを有するミラー本体と、ミラー本体の支持基盤に摺動可能に連結する球状頭部を有する連結部材と、を備え、支持基盤と球状頭部とを相対的に摺動させて首振自在とすると共に支持基盤と球状頭部の摩擦力によってミラー本体を所望の角度に保持するようにした構造があった（例えば、特許文献１参照）。
しかし、ミラー本体の角度調整（首振）を繰り返し行うと支持基盤や球状頭部が磨耗して摩擦力が低下し、ミラー本体を所望の角度に保持できないといった問題があった。また、屋外においては、強風や積雪等によりミラー本体の角度が変わってしまうといった問題があった。
そこで、支持基盤の背面に、球状頭部を挟持状に保持する一対のクランプ部材を設け、一対のクランプ部材を相対的に接近させるようにボルト部材で締付け、球状頭部への摩擦力を高めて、ミラー本体を所望の角度で固定可能とした構造があった（例えば、特許文献２参照）。 Conventionally, mirror angle adjustment structures such as garage mirrors and in-store security mirrors are slidably connected to a mirror body having a mirror body and a support base for holding the mirror body from the back side of the mirror, and to the support base of the mirror body. A connecting member having a spherical head, and by allowing the support base and the spherical head to slide relative to each other so as to freely swing, the mirror body is brought to a desired angle by the frictional force of the support base and the spherical head. There was a structure to hold (see, for example, Patent Document 1).
However, when the angle adjustment (swinging) of the mirror body is repeated, there is a problem that the support base and the spherical head are worn and the frictional force is lowered, and the mirror body cannot be held at a desired angle. In addition, outdoors, there is a problem that the angle of the mirror body changes due to strong winds or snow.
Therefore, a pair of clamp members that hold the spherical head in a sandwiched manner are provided on the back surface of the support base, and tightened with a bolt member so that the pair of clamp members are relatively close to each other, thereby increasing the frictional force on the spherical head. Thus, there has been a structure in which the mirror body can be fixed at a desired angle (for example, see Patent Document 2).

球状頭部20が半球状凹部11に接近して、球状頭部20の中心Ｑが先端膨出部12ｄよりも前方位置となると、圧接突片12は弾性的復元力にて、ラジアル内方向へ戻り、球状頭部20を飲み込んで、凹曲内面11ａに押し付けると共に、弯曲内面12ａが球状頭部20に圧接し、図４に示すように、凹曲内面11ａ及び弯曲内面12ａの中心点Ｐａと、球状頭部20の中心Ｑとが一致し、断面視で、球状頭部20を、半球状凹部11と圧接突片12とで（凹曲内面11ａと弯曲内面12ａとで）Ｃ字抱き込み状に保持した連結状態となる。 Next, an operation (usage method) of the mirror angle adjustment structure of the present invention will be described.
As shown in FIG. 3, when the hemispherical concave portion 11 and the spherical head 20 are brought relatively close to each other, the spherical head 20 is brought into sliding contact with the guide inner surface 12 f of the press contact protrusion 12, so that the reference axis La is formed. When the center Q of the spherical head 20 is disposed and further approached, the inlet inner surface 12c is pressed radially outward along the curved surface of the spherical head 20, and the plurality of press contact protrusions 12 are elastically deformed.
When the spherical head 20 approaches the hemispherical concave portion 11 and the center Q of the spherical head 20 is positioned forward of the tip bulging portion 12d, the pressing contact piece 12 is moved radially inward by an elastic restoring force. Returning, the spherical head 20 is swallowed and pressed against the concave inner surface 11a, and the curved inner surface 12a is pressed against the spherical head 20, and the center points Pa of the concave inner surface 11a and the curved inner surface 12a as shown in FIG.

この連結状態において、支持基盤１と連結部材２の間に、所定離間操作力以上の引張力が作用すると、球状頭部20に沿って圧接突片12がラジアル外方向へ弾性変形して、工具無しで連結を解除できる（分離できる）。 In the connected state shown in FIG. 4, the spherical head 20 and the support base 1 (the pressure contact protrusion 12 and the hemispherical concave portion 11) can slide (slidably contact) relative to each other, and the support base 1 (Mirror body M) can swing freely, and the mirror angle can be freely adjusted (mirror angle adjustable state).
In this connected state, when a tensile force greater than a predetermined separation operating force is applied between the support base 1 and the connecting member 2, the pressure contact protrusion 12 is elastically deformed radially outward along the spherical head 20, and the tool Can be disconnected (separated) without.

そして、キャップ部材３を環状筒部13に接近させ、支持基盤１の雄ネジ部13ａにキャップ部材３の雌ネジ部31ｄに螺着して螺進させると、テーパ状内周面32ｄが前進して各圧接突片12のガイド勾配外面12ｅに摺接し、螺進に伴って、圧接突片12の先端部乃至中間部（傾斜内面12ｂ及び入口内面12ｃ）をラジアル内方向へ倒していって、球状頭部20へ押圧する。テーパ状内周面32ｄの前進に伴うテーパ作用により、圧接突片12をラジアル内方へ倒す力が次第に強くなる。そして、キャップ部材３が螺進するにつれて、球状頭部20と支持基盤１との摩擦力を高めると共に、圧接突片12のラジアル外方向へ弾性変形を阻止し、図５に示す螺進終了状態で、球状頭部20と支持基盤１（圧接突片12及び半球状凹部11）とが強力に圧接され、支持基盤１の首振（角度調整）が阻止されて首振阻止状態となる。
なお、連結部材２と取付金具６の固着は、連結部材２をキャップ部材３に挿通させておけば、支持基盤１と連結部材２との連結前又は後、或いは、支持基盤１とキャップ部材３の螺着の前又は後、いずれのタイミングで行っても良い。 Then, when the cap member 3 is brought close to the annular cylindrical portion 13 and screwed into the female screw portion 31d of the cap member 3 to the male screw portion 13a of the support base 1, the tapered inner peripheral surface 32d advances. The sliding contact with the guide gradient outer surface 12e of each pressing contact piece 12, and with the screwing, the tip or intermediate portion (inclined inner surface 12b and inlet inner surface 12c) of the pressing contact piece 12 is tilted radially inward, Press against the spherical head 20. Due to the taper action associated with the advancement of the tapered inner peripheral surface 32d, the force for inclining the pressure contact protrusion 12 radially inward gradually increases. Then, as the cap member 3 is screwed, the frictional force between the spherical head 20 and the support base 1 is increased, and elastic deformation of the press-contact projection piece 12 is prevented in the radial outward direction, and the screwing end state shown in FIG. Thus, the spherical head 20 and the support base 1 (the pressure contact protrusion 12 and the hemispherical recess 11) are pressed strongly, and the swinging (angle adjustment) of the support base 1 is blocked and a swing blocking state is obtained.
Note that the connection member 2 and the mounting bracket 6 can be fixed by inserting the connection member 2 through the cap member 3 before or after the connection between the support base 1 and the connection member 2, or the support base 1 and the cap member 3. It may be performed at any timing before or after the screwing.

そして、ミラー確認位置からミラー本体Ｍを確認して、所望の確認位置が視認できていない、或いは、所望の確認位置をより見易くする等の理由により、ミラー角度を調整する場合は、キャップ部材３を手で螺退させ、テーパ状内周面32ｄによる圧接突片12への押圧を解除又は弱めることで、図４に示すように、球状頭部20と、圧接突片12及び半球状凹部11との摩擦力が弱まって相対的摺動が可能となり、ミラー角度調整可能状態となる。
作業者は、スパナやドライバ等の工具を用いずに手動で（手で）、ミラー角度調整作業を行うことができる。また、連結部材２を取付金具６から取り外す必要もない。 Then, when the mirror body M is confirmed from the mirror confirmation position and the desired confirmation position is not visually recognized or the mirror angle is adjusted for reasons such as making the desired confirmation position easier to see, the cap member 3 is used. 4 is released by hand to release or weaken the pressure on the pressure contact protrusion 12 by the tapered inner peripheral surface 32d, as shown in FIG. 4, the spherical head 20, the pressure contact protrusion 12 and the hemispherical recess 11 And the relative sliding becomes possible, and the mirror angle can be adjusted.
An operator can perform mirror angle adjustment work manually (by hand) without using a tool such as a spanner or a driver. Further, it is not necessary to remove the connecting member 2 from the mounting bracket 6.

なお、図４において、説明を容易にするために、キャップ部材３を支持基盤１から分離した状態をミラー角度調整可能状態（首振調整可能状態）としているが、キャップ部材３を螺退させて、テーパ状内周面32ｄによる圧接突片12への押圧力を弱めて、球状頭部20と、圧接突片12及び半球状凹部11とが、相対的に摺動可能となれば、キャップ部材３が環状筒部13に螺着した状態であっても良い。   In FIG. 4, for ease of explanation, the state in which the cap member 3 is separated from the support base 1 is the mirror angle adjustable state (oscillation adjustable state), but the cap member 3 is screwed back. If the pressing force to the pressure contact protrusion 12 by the tapered inner peripheral surface 32d is weakened so that the spherical head 20, the pressure contact protrusion 12 and the hemispherical recess 11 are relatively slidable, the cap member 3 may be in a state of being screwed to the annular tube portion 13.

そして、支持基盤１（ミラー本体Ｍ）を所望の角度に調整後、再び、図５に示すようにキャップ部材３を螺進させ、テーパ状内周面32ｄで圧接突片12を押圧して摩擦力を高めることで、支持基盤１が固定される。また、キャップ部材３の螺進完了状態において、貫通孔31ｆは、複数の凹部52のいずれかとラジアル方向に連通（対応）する。
ミラー確認位置から見て所望の確認位置が視認できれば、図６に示すように、螺進完了状態のキャップ部材３の貫通孔31ｆに、ロックピン部材５を接近させる。
図７に示すように、螺進完了状態のキャップ部材３の貫通孔31ｆに、ロックピン部材５のピン部５ａを挿通させ、ピン部５ａを収納空間39内の凹部52に差し込んで、キャップ部材３のゆるみ止めを行う。 Then, after adjusting the support base 1 (mirror body M) to a desired angle, the cap member 3 is screwed again as shown in FIG. 5, and the pressure contact protrusion 12 is pressed by the tapered inner peripheral surface 32d to be rubbed. The support base 1 is fixed by increasing the force. Further, when the screwing of the cap member 3 is completed, the through hole 31f communicates (corresponds) with any one of the plurality of recesses 52 in the radial direction.
If the desired confirmation position can be visually recognized from the mirror confirmation position, the lock pin member 5 is brought close to the through hole 31f of the cap member 3 in the screwing completion state as shown in FIG.
As shown in FIG. 7, the pin portion 5a of the lock pin member 5 is inserted into the through hole 31f of the cap member 3 in the screwing completed state, and the pin portion 5a is inserted into the recess 52 in the storage space 39 to 3) Stop loosening.

And a locking frame portion 5c that forms a window portion 5d into which the portion 33a enters.

図７に示すように、ピン部５ａを貫通孔31ｆに差し込むと、当り鍔部５ｂが外筒状壁部31に当接すると共に、係止枠部５ｃの先端枠部が小凸部33ａを乗り越え、窓部５ｄに小凸部33ａが入りこんで係止枠部５ｃに係止（係合）し、ロックピン部材５の抜けが防止される。係止枠部５ｃの先端枠部を爪や指で引くことで、係止枠部５ｃが弾性変形して、先端枠部が小凸部33ａを乗り越えて、ロックピン部材５をキャップ部材３から離脱させることが可能となるように構成している。   As shown in FIG. 7, when the pin portion 5a is inserted into the through hole 31f, the contact flange portion 5b comes into contact with the outer cylindrical wall portion 31, and the distal end frame portion of the locking frame portion 5c gets over the small convex portion 33a. The small convex portion 33a enters the window portion 5d and is locked (engaged) with the locking frame portion 5c, so that the lock pin member 5 is prevented from coming off. By pulling the tip frame portion of the lock frame portion 5c with a nail or a finger, the lock frame portion 5c is elastically deformed, the tip frame portion gets over the small convex portion 33a, and the lock pin member 5 is removed from the cap member 3. It is configured so that it can be detached.
