Description

本発明は、扉等の開閉体から屋内側へ回動自在に突出され、開閉体に内設された錠箱に対して施解錠操作力を入力するサムターンに関する。 The present invention relates to a thumb turn that protrudes from an opening / closing body such as a door to the indoor side and inputs a locking / unlocking operation force to a lock box provided inside the opening / closing body.

例えば扉などの開閉体には錠箱が内蔵され、錠箱には、開閉体の屋外側に露出するシリンダー錠と、開閉体の屋内側に露出する回転式のサムターンとが接続されている。錠箱には、ロック部材である例えばデッドボルトが開閉体の端面（木口）から進退自在に設けられている。錠箱は、屋外側に露出したシリンダー錠の鍵孔に、合鍵（キー）が挿入されて回転操作されることによって、開閉体の木口よりデッドボルトを進退させ、開口枠体（引戸枠又は扉枠）に設けたストライクに対して施解錠を可能にする。また、屋内側からは、サムターンの摘みが回転操作されるのみで、デッドボルトが進退され、開閉体の施解錠が簡便に行われる。 For example, an opening / closing body such as a door incorporates a lock box, and a cylinder lock exposed to the outdoor side of the opening / closing body and a rotary thumb turn exposed to the indoor side of the opening / closing body are connected to the lock box. The lock box is provided with, for example, a dead bolt, which is a lock member, so as to be able to advance and retreat from the end face (the end) of the opening / closing body. The lock box is inserted into the keyhole of the cylinder lock exposed on the outdoor side, and the dead bolt is moved forward and backward from the mouth of the opening and closing body by rotating the key by inserting the key (key). It is possible to lock and unlock the strike provided in the frame. Further, from the indoor side, only the thumb turn knob is rotated, the deadbolt is advanced and retracted, and the opening and closing body is easily locked and unlocked.

一般的にサムターンは、水平又は垂直の向きが分かり易い形状、例えば板状に形成されるか、或いは水平又は垂直の向きが分かり難い略円柱形状等のものでは印刷や刻印による標示が付されている。これにより、サムターンは、屋内側から目視された際、水平又は垂直に配置されているかが分り、その結果、錠箱の施解錠状態を把握可能にしていた。 In general, the thumb turn is formed in a shape that makes it easy to understand the horizontal or vertical orientation, for example, a plate shape, or a substantially cylindrical shape that is difficult to understand in the horizontal or vertical orientation, and is marked by printing or marking. Yes. As a result, when the thumb turn is viewed from the indoor side, it can be seen whether the thumb turn is arranged horizontally or vertically, and as a result, the lock state of the lock box can be grasped.

しかしながら、板状等の形状によって水平又は垂直の向きを視認させる従来のサムターンは、円板状の基台等に摘み部材が突設されていると、摘み部材と基台とが一体となって見え、水平又は垂直の向きが視認し難い問題があった。また、印刷や刻印によって標示が付されたサムターンでは、経年劣化によって標示が退色や変色し、視認性が低下する問題があった。そして、これら構造的な欠点や、着色上の不具合を解消しようとしても、従来のサムターンでは施錠装置ごとの交換しか対応の手立てがなかった。 However, in the conventional thumb turn that visually recognizes the horizontal or vertical orientation by the shape of a plate or the like, when the knob member protrudes from a disk-shaped base or the like, the knob member and the base are integrated. There was a problem that it was difficult to see the horizontal or vertical orientation. In addition, the thumb turn marked by printing or engraving has a problem that the marking is faded or discolored due to deterioration over time, and the visibility is lowered. And even if it was going to eliminate these structural faults and troubles in coloring, the conventional thumb turn could only cope with replacement for each locking device.

本発明は上記状況に鑑みてなされたもので、施解錠状態を把握するための標示部材の視認性を向上させるとともに、この標示部材を容易に交換可能とするサムターンを提供することを目的とする。 The present invention has been made in view of the above situation, and it is an object of the present invention to improve the visibility of a marking member for grasping the locked / unlocked state, and to provide a thumb turn that allows the marking member to be easily replaced. .

次に、上記の課題を解決するための手段を、実施の形態に対応する図面を参照して説明する。

FIG. 1 is an exploded plan view of a first embodiment of a thumb turn according to the present invention, FIG. 2 is an exploded perspective view of the thumb turn shown in FIG. 1, and FIG. It is explanatory drawing.
The thumb turn 100 according to the present embodiment inputs a locking / unlocking operation force to a lock box (not shown) provided on the door 1 which is an opening / closing body. The thumb turn 100 has a thumb turn shaft 3. The thumb turn shaft 3 has one end connected to the lock box and the other end protruding vertically from the indoor-side surface 1a of the door 1 so as to be rotatable. The thumb turn shaft 3 is rotatably supported inside a cylinder (not shown) fixed to the lock box. This cylindrical body is covered with a conical decorative ring 5 having a flat tip.

サムターン軸３の他端には摘み部材７が固設される。本実施の形態において、摘み部材７は、図２に示すように、長円板を短径方向で分割した略半円形状に形成され、短径方向の中央部がサムターン軸３に固定されている。また、表裏面には指先での把持性を良好にする凹部９が形成される。この摘み部材７の表裏面に挟まれる外周（厚み方向に延在する面）は、半円弧とこの半円弧の両端に連なる略平行な直線部とからなる。 A knob member 7 is fixed to the other end of the thumb turn shaft 3. In the present embodiment, as shown in FIG. 2, the knob member 7 is formed in a substantially semicircular shape obtained by dividing the long disk in the short diameter direction, and the central portion in the short diameter direction is fixed to the thumb turn shaft 3. Yes. Moreover, the recessed part 9 which makes the grip property with a fingertip favorable is formed in front and back. The outer periphery (surface extending in the thickness direction) sandwiched between the front and back surfaces of the knob member 7 is composed of a semicircular arc and substantially parallel straight portions connected to both ends of the semicircular arc.

この摘み部材７の外周には略Ｃ字形状の収容部１１が形成される。収容部１１は、両側部１３，１３に凹設され、サムターン軸３の軸線１５に沿う一対の側面溝１７，１７、及びこの一対の側面溝１７，１７を連結する連結溝１９からなる。収容部１１は、略Ｃ字形状の収容空間が形成されればよく、その収容空間外に、図１に示す摘み部材７の内部構造部２１が臨むものであってもよい。なお、図１中２３は、摘み部材７をサムターン軸３に固定するためのビスを表す。 A substantially C-shaped accommodation portion 11 is formed on the outer periphery of the knob member 7. The accommodating portion 11 includes a pair of side surface grooves 17 and 17 that are recessed in the both side portions 13 and 13 along the axis 15 of the thumb turn shaft 3, and a connection groove 19 that connects the pair of side surface grooves 17 and 17. The accommodating part 11 should just form the substantially C-shaped accommodation space, and the internal structure part 21 of the knob member 7 shown in FIG. 1 may face the accommodation space. In FIG. 1, reference numeral 23 denotes a screw for fixing the knob member 7 to the thumb turn shaft 3.

この収容部１１には略Ｃ字形状の標示部材２５が着脱自在に嵌合されるようになっている。標示部材２５は、バネ性を有し、摘み部材７と異なる色に着色されている。着色は、一色であってもよく、標示部材２５の円弧方向の略中央部を境に、左右が異なる色で２色に色分けされてもよい。このような色分けを行うことで、摘み部材７が水平又は垂直に姿勢された際の、上下又は左右を判別し易くすることができる。 A substantially C-shaped marking member 25 is detachably fitted into the housing portion 11. The marking member 25 has a spring property and is colored in a color different from that of the knob member 7. The coloring may be one color, and may be color-coded into two colors with different colors on the left and right sides of the substantially central portion of the marking member 25 in the arc direction. By performing such color coding, it is possible to easily distinguish the top and bottom or the left and right when the knob member 7 is positioned horizontally or vertically.

また、着色には、蛍光塗料を用いることができ、反射光の強度を高めて視認性を向上させることができる。また、着色には蓄光材料を用いることができ、この場合には暗所での視認性を向上させることができる。 In addition, a fluorescent paint can be used for coloring, and the visibility can be improved by increasing the intensity of reflected light. Further, a phosphorescent material can be used for coloring, and in this case, visibility in a dark place can be improved.

本実施の形態では、標示部材２５は、合成樹脂材、例えばポリカーボネート樹脂などからなる。このように合成樹脂材が用いられることで、一体成形が可能となり、バネ性を備えた精度の高い標示部材２５が、自由な形状でかつ安価に大量製造可能となる。また、成形前の樹脂材料に顔料（蛍光塗料、蓄光材料を含む）等が添加されることで着色が可能となり、塗布の場合に比べ、退色や変色のしにくい着色が可能となる。 In the present embodiment, the marking member 25 is made of a synthetic resin material such as polycarbonate resin. By using the synthetic resin material in this way, integral molding is possible, and the highly accurate marking member 25 having a spring property can be freely manufactured and mass-produced at low cost. Further, by adding a pigment (including a fluorescent paint and a phosphorescent material) or the like to the resin material before molding, coloring becomes possible, and coloring that is less likely to fade or discolor compared to the case of application is possible.

標示部材２５は、表面が、摘み部材７の表面に対して段差を生じさせない連続面で形成される。図２（ｂ）に示すように、標示部材２５が収容部１１に装着されると、摘み部材７の表面と標示部材２５の表面とが段差のない連続表面となり、違和感の生じない把持が可能となり、操作性が良好となる。また、段差の生じないことによって、不正回転操作に用いられる棒や針金の引っ掛かりが防止され、防犯性も高まる。さらに、標示部材２５が摘み部材７の表面から突出された構造で生じやすい衝突による破損や、逆に標示部材２５が凹んだ構造での汚れの堆積も防止可能となる。 The marking member 25 is formed with a continuous surface whose surface does not cause a step with respect to the surface of the knob member 7. As shown in FIG. 2B, when the marking member 25 is attached to the housing portion 11, the surface of the knob member 7 and the surface of the marking member 25 become a continuous surface without a step, and can be gripped without causing a sense of incongruity. Thus, operability is improved. Further, since no step is generated, the sticks and wires used for the illegal rotation operation are prevented from being caught, and the crime prevention property is improved. Furthermore, it is possible to prevent damage caused by a collision that is likely to occur in the structure in which the marking member 25 protrudes from the surface of the knob member 7, and conversely, dirt accumulation in the structure in which the marking member 25 is recessed.

なお、本実施の形態では、収容部１１に臨む内部構造部２１の先端部には凸部２７が形成されている。標示部材２５の円弧内側にはこの凸部２７に係合する嵌合部２９が形成されている。
摘み部材７と標示部材２５には、標示部材２５を摘み部材７に弾性的に係止する係止手段３１が設けられている。係止手段３１は、例えば標示部材２５の両端に突設した一対の爪部３３，３３と、内部構造部２１の基部両側に設けた一対の係止段部３５，３５とから構成できる。 In the present embodiment, a convex portion 27 is formed at the distal end portion of the internal structure portion 21 that faces the accommodating portion 11. A fitting portion 29 that engages with the convex portion 27 is formed inside the arc of the marking member 25.
The knob member 7 and the marking member 25 are provided with locking means 31 for elastically locking the marking member 25 to the knob member 7. The locking means 31 can be composed of, for example, a pair of claw portions 33 and 33 projecting from both ends of the marking member 25 and a pair of locking step portions 35 and 35 provided on both sides of the base portion of the internal structure portion 21.

標示部材２５は、摘み部材７の正面側から、両端で内部構造部２１を挟むように収容部１１へ挿入されると、爪部３３，３３が係止段部３５，３５に当り、さらに押し込まれることで、弾性変形して開脚され、爪部３３，３３が係止段部３５，３５を乗り越え、弾性復帰力によって再び閉脚されることで、係止段部３５，３５に係止される。脱着の際には、一方の爪部３３をドライバ等の工具等を用いて係止段部３５から離反させれば、係止が解除される。これにより、容易な着脱が可能となっている。 When the marking member 25 is inserted from the front side of the knob member 7 into the accommodating portion 11 so as to sandwich the internal structure portion 21 at both ends, the claw portions 33 and 33 come into contact with the locking step portions 35 and 35 and are pushed further. As a result, the legs are elastically deformed and the claw portions 33, 33 get over the locking step portions 35, 35 and are closed again by the elastic restoring force, thereby being locked to the locking step portions 35, 35. The At the time of detachment, if one of the claw portions 33 is separated from the locking step portion 35 using a tool such as a driver, the locking is released. Thereby, easy attachment and detachment are possible.

このサムターン１００では、摘み部材７が扉１の屋内側、すなわち、正面側から目視されると、標示部材２５が摘み部材７と異なる色で直線状に見え、錠箱の施解錠状態に応じて、標示部材２５が水平又は垂直に配置されることで、摘み部材７の向き（施錠回転姿勢又は解錠回転姿勢）が明確に把握可能となる。また、標示部材２５が収容部１１に対して着脱自在となることで、容易に交換が可能となる。 In this thumb turn 100, when the knob member 7 is viewed from the indoor side of the door 1, that is, from the front side, the marking member 25 looks straight in a color different from that of the knob member 7, and according to the locking / unlocking state of the lock box. By arranging the marking member 25 horizontally or vertically, the orientation of the knob member 7 (locking rotation posture or unlocking rotation posture) can be clearly grasped. In addition, since the marking member 25 is detachably attached to the housing portion 11, it can be easily replaced.

したがって、このサムターン１００によれば、摘み部材７の外周に略Ｃ字形状の収容部１１を凹設し、この収容部１１に対して、バネ性を有し摘み部材７と異なる色に着色された略Ｃ字形状の標示部材２５を、係止手段３１によって弾性的に係止したので、摘み部材７を正面視すると、標示部材２５が摘み部材７と異なる色で直線状に見え、この標示部材２５が水平又は垂直に配置されることで、摘み部材７の向き（施錠回転姿勢又は解錠回転姿勢）が明確に把握可能となり、施解錠状態の視認性を高めることができる。また、標示部材２５は、着脱自在であるので容易に交換でき、購入後であっても、好みの色や、周囲のデザイン，配色に合せた色、色弱者の場合にはより認識しやすい色への簡単な変更が可能となり、色選択の自由度を向上させることができる。 Therefore, according to the thumb turn 100, a substantially C-shaped accommodation portion 11 is recessed in the outer periphery of the knob member 7, and the accommodation portion 11 has a spring property and is colored in a color different from that of the knob member 7. Since the substantially C-shaped marking member 25 is elastically locked by the locking means 31, when the knob member 7 is viewed from the front, the marker member 25 looks linear in a color different from that of the knob member 7. By arranging the member 25 horizontally or vertically, the direction of the knob member 7 (locking rotation position or unlocking rotation position) can be clearly grasped, and the visibility of the locking / unlocking state can be improved. In addition, the marking member 25 is detachable so that it can be easily replaced. Even after purchase, it can be easily recognized if it is a favorite color, a color that matches the surrounding design and color scheme, or a person with weak color.

図３は第２の実施の形態に係るサムターンの分解斜視を（ａ）、標示部材装着状態の斜視を（ｂ）に表した説明図である。なお、図１，図２に示した部材と同一の部材には同一の符号を付すものとする。
このサムターン２００は、摘み部材４１が略四角形に形成される。摘み部材４１の表裏面に挟まれる外周（厚み方向に延在する面）には、略Ｃ字形状の収容部４３が形成される。この収容部４３には略Ｃ字形状の標示部材４５が着脱自在に嵌合される。標示部材４５は、バネ性を有し、摘み部材４１と異なる色に着色されている。 Next, a second embodiment of the thumb turn according to the present invention will be described.
FIG. 3 is an explanatory view showing an exploded perspective view of the thumb turn according to the second embodiment in (a) and a perspective view in a state where the marking member is mounted in (b). In addition, the same code | symbol shall be attached | subjected to the member same as the member shown in FIG. 1, FIG.
In the thumb turn 200, the knob member 41 is formed in a substantially square shape. A substantially C-shaped accommodation portion 43 is formed on the outer periphery (the surface extending in the thickness direction) sandwiched between the front and back surfaces of the knob member 41. A substantially C-shaped marking member 45 is detachably fitted in the housing portion 43. The marking member 45 has a spring property and is colored in a color different from that of the knob member 41.

この標示部材４５も、表面が、摘み部材４１の表面に対して段差を生じさせない連続面で形成される。図３（ｂ）に示すように、標示部材４５が収容部４３に装着されると、摘み部材４１の表面と標示部材２５の表面とが段差のない連続表面となり、違和感の生じない把持が可能となり、操作性が良好となる。 The surface of the marking member 45 is also a continuous surface that does not cause a step with respect to the surface of the knob member 41. As shown in FIG. 3B, when the marking member 45 is attached to the housing portion 43, the surface of the knob member 41 and the surface of the marking member 25 become a continuous surface without a step, and can be gripped without causing a sense of incongruity. Thus, operability is improved.

したがって、このサムターン２００によれば、上記のサムターン１００と同様、摘み部材４１を正面視すると、標示部材４５が摘み部材４１と異なる色で直線状に見え、この標示部材４５が水平又は垂直に配置されることで、摘み部材４１の向き（施錠回転姿勢又は解錠回転姿勢）が明確に把握可能となり、施解錠状態の視認性を高めることができる。また、標示部材４５は、着脱自在であるので容易に交換でき、購入後であっても、好みの色や、サムターン周囲のデザインやカラーリングに合せた色、色弱者の場合にはより認識しやすい色への簡単な変更が可能となり、色選択の自由度を向上させることができる。 Therefore, according to the thumb turn 200, as with the thumb turn 100, when the knob member 41 is viewed from the front, the marking member 45 looks linear with a different color from the knob member 41, and the marking member 45 is arranged horizontally or vertically. By doing so, the direction (locking rotation posture or unlocking rotation posture) of the knob member 41 can be clearly grasped, and the visibility of the locked / unlocked state can be enhanced. The marking member 45 is detachable so that it can be easily replaced. Even after purchase, the marking member 45 is more recognizable in the case of a favorite color, a color that matches the design and coloring around the thumb turn, or a color weak person. A simple change to an easy color is possible, and the degree of freedom in color selection can be improved.

次に、本発明に係るサムターンの第３の実施の形態を説明する。
図４は第３の実施の形態に係るサムターンの分解斜視を（ａ）、標示部材装着状態の斜視を（ｂ）に表した説明図である。なお、図１，図２に示した部材と同一の部材には同一の符号を付すものとする。
このサムターン３００は、摘み部材５１の表裏面が上下方向に突出する湾曲面５３で形成され、平面視が四角形で、正面視が略楕円形状に形成される。摘み部材５１の表裏面に挟まれる外周（厚み方向に延在する面）には、略Ｃ字形状の収容部５５が形成される。この収容部５５には略Ｃ字形状の標示部材５７が着脱自在に嵌合される。標示部材５７は、バネ性を有し、摘み部材５１と異なる色に着色されている。 Next, a third embodiment of the thumb turn according to the present invention will be described.
FIG. 4 is an explanatory view showing an exploded perspective view of the thumb turn according to the third embodiment in (a) and a perspective view in a state where the marking member is mounted in (b). In addition, the same code | symbol shall be attached | subjected to the member same as the member shown in FIG. 1, FIG.
The thumb turn 300 is formed by a curved surface 53 in which the front and back surfaces of the knob member 51 protrude in the vertical direction. The thumb turn 300 is formed in a square shape in plan view and in a substantially elliptical shape in front view. A substantially C-shaped accommodation portion 55 is formed on the outer periphery (the surface extending in the thickness direction) sandwiched between the front and back surfaces of the knob member 51. A substantially C-shaped marking member 57 is detachably fitted in the housing portion 55. The marking member 57 has a spring property and is colored in a color different from that of the knob member 51.

この標示部材５７も、表面が、摘み部材５１の表面に対して段差を生じさせない連続面で形成される。図４（ｂ）に示すように、標示部材５７が収容部５５に装着されると、摘み部材５１の表面と標示部材５７の表面とが段差のない連続表面となり、違和感の生じない把持が可能となり、操作性が良好となる。 The surface of the marking member 57 is also a continuous surface that does not cause a step with respect to the surface of the knob member 51. As shown in FIG. 4B, when the marking member 57 is attached to the accommodating portion 55, the surface of the knob member 51 and the surface of the marking member 57 become a continuous surface without a step, and can be gripped without causing a sense of incongruity. Thus, operability is improved.

したがって、このサムターン３００によれば、上記のサムターン１００と同様、摘み部材５１を正面視すると、標示部材５７が摘み部材５１と異なる色で直線状に見え、この標示部材５７が水平又は垂直に配置されることで、摘み部材５１の向き（施錠回転姿勢又は解錠回転姿勢）が明確に把握可能となり、施解錠状態の視認性を高めることができる。また、標示部材５７は、着脱自在であるので容易に交換でき、購入後であっても、好みの色や、周囲のデザイン等に合せた色、色弱者の場合にはより認識しやすい色への簡単な変更が可能となり、色選択の自由度を向上させることができる。 Therefore, according to the thumb turn 300, as with the thumb turn 100, when the knob member 51 is viewed from the front, the marking member 57 looks linear with a different color from the knob member 51, and the marking member 57 is disposed horizontally or vertically. By doing so, the direction of the knob member 51 (locking rotation posture or unlocking rotation posture) can be clearly grasped, and the visibility of the locking / unlocking state can be enhanced. The marking member 57 is detachable so that it can be easily replaced. Even after purchase, it can be easily recognizable in the case of a favorite color, a color that matches the surrounding design, or a color weak person. Can be easily changed, and the degree of freedom in color selection can be improved.
