Description

【０００１】
【発明の属する技術分野】
本発明は、壁や柱や掲示板等に紙やポスターやカレンダー等を取付けるための画鋲に関するものである。
【０００２】
【従来の技術】
従来の画鋲は、周知のように、平円板本体とこの中心から突出する針を具備しており、これを壁や柱や掲示板等に紙やポスターやカレンダー等を取付けたのち、壁や柱や掲示板等から離脱させる必要のあるときは、画鋲の平円板本体を摘持して離脱させることが行われている。
しかし、従来の画鋲は、紙やポスターやカレンダー等を取付ける際確実に取付けるために針の根元まで押し込む必要があり、その反面、前記離脱のためにかなりの力が必要であり、また、逆に取りやすい様に浅く押し込んでおいた場合には、わずかの影響ですぐに外れてしまう等の問題を有していた。
そこで、実開昭４８−７１９３９号や実開昭５０−１４４７４３号において、取外しが容易にできるようにテコの働きを利用した画鋲が知られている。実開昭４８−７１９３９号は、画鋲本体上部の一部を上方に曲げた画鋲であって、引抜く際には、上方に曲げた部分から相対する端部を常に支点とし、指にて画鋲の頭を軽く押え、上方に曲った部分を起こすようにテコの作用を利用して離脱させる。また、実開昭５０−１４４７４３号は、画鋲本体上部の凹型の溝に合うように嵌め込んだテコ板が、テコ板の内部を通っている棒軸を支点として、テコ板がシーソ式に上下に動作する画鋲であって、引抜く際にテコ板を用いて画鋲本体と壁や掲示板との間を浮き上らせて予め隙間をつくり、その後、画鋲の平円板本体を摘持して離脱させる。
【０００３】
【発明が解決しようとする課題】
しかし、実開昭４８−７１９３９号の画鋲は、離脱させる必要のあるときは指にて画鋲の頭を軽く押さえて支点を支える必要があったり、実開昭５０−１４４７４３号の画鋲は、引抜く際にテコ板を用いて画鋲本体と壁や掲示板との間を浮き上らせて予め隙間をつくり、その後、画鋲の平円板本体を摘持して離脱させるためワンタッチでなかったり、また、双方とも力点を引き起こす際に支点を支えるように介添する必要があるため、固定されていない掲示板等から画鋲を離脱する際の安定性において問題があった。
本発明の目的は、紙やポスターやカレンダー等を確実に取付けることができ、しかもワンタッチで容易に離脱できる画鋲を提供することにある。
【０００４】
【課題を解決するための手段】
そこで本発明は、上記のような既知の画鋲にかわる新規な構造を有する画鋲を提案するもので、本発明画鋲の特徴は、頂面から少なくとも１本の針が突出してなる画鋲本体の前記頂面の周縁部に、壁や柱や掲示板等に取付けられた状態で同頂面と実質的に平行な押圧部となる部分と、同押圧部に繋がり画鋲本体の側面に沿って延びる操作部とからなるレバーを、回転軸を介して回動自在に取付けたことにより、当該レバーのテコ作動が針を引抜く力に代わるため、支点を支える必要なく指による摘み力によって、固定されていない掲示板等からもワンタッチで容易に安定して画鋲を離脱させることができる。
【０００５】
【実施例】
本発明の第１実施例である一個の画鋲離脱用レバーを形成した例について、第１図、第２図、第３図より説明する。第１図は本発明の第１実施例を示す図であり、図示するように、画鋲本体１の頂面から針２と２’が突出し、針２と２’の間に画鋲離脱用レバー３を回動可能となるように取付けられている。この画鋲離脱用レバー３は、壁や柱や掲示板等に取付けられた状態で画鋲本体１の頂面と実質的に平行な押圧部３２と、該押圧部３２に繋がり画鋲本体１の側面に沿ってのびる操作部３１で構成される大略Ｌ字状のレバーであり、これは回転軸４により画鋲本体１に対して回動自在に装着されている。
以上の構成を具備する本発明の画鋲では、画鋲離脱用レバー３を操作することによって、壁や柱や掲示板等に取付けられた画鋲を極めて容易に離脱させることができる。
第２図および第３図は、本発明第１実施例の壁からの離脱方法について説明するための図であり、第２図は壁へ取付けられている状態を、また第３図はレバー操作で壁からの離脱がなされている状態をそれぞれ示す。
第２図で示されるように、針２を用いて壁６に紙５を挟持させた状態では、画鋲離脱用レバー３の押圧部３２は壁６の面と平行になっている。したがって、周知の画鋲の取付け状態とは何ら遜色はない。
ところで、この画鋲を壁６から離脱させる場合は、画鋲離脱用レバー３の操作部３１を矢印Ｘで示すように画鋲本体１へ向かって押圧すればよい。
第３図は、この押圧がなされた直後の状態を示す図である。前述したように画鋲離脱用レバー３は、回転軸４により画鋲本体１へ回動自在に取付けられているため、矢印Ｘ方向の押圧力によって回動する。このため押圧部３２は、図示するように回転軸４を支点にして回動する。この回動により壁６の面を押圧する。この押圧力は、画鋲を離脱させる方向の力として作用するところとなり、画鋲は壁６から離脱する。
すなわち、レバー操作で画鋲本体１と壁６との間には間隙Ｌが付与される。レバー操作で針２を壁６から完全に離脱させるには間隙Ｌを大きくすればよく、したがってレバー操作による回動量を大きくする配慮を払えばよい。
以上、本発明の画鋲を１例をもって説明したが、画鋲離脱用レバー３の取付けは回転軸のみを利用してなす必要はない。
【０００６】
本発明の第２実施例である他の形状の画鋲離脱用レバーを形成した例について、第４図より説明する。第４図は、他形状の画鋲離脱用レバー３の取付けがなされた、本発明の画鋲の例を示す図である。図示するように、画鋲本体１の頂面から針２と２’が突出し、針２と２’の左右両側部に押圧部３２と３２’を有する画鋲離脱用レバー３が取付けられている。この画鋲離脱用レバー３は、壁や柱や掲示板等に取付けられた状態で画鋲本体１の頂面と実質的に平行な押圧部３２、３２’と、この押圧部に繋がり画鋲本体の側面に沿ってのびる操作部３１で構成され、左右対称に２本の押圧部３２、３２’を有しているため大略Ｕ字形状のレバーである。これは回転軸４により画鋲本体１に対して回動自在に装着されている。この構造とした場合には、画鋲離脱用レバー３が、左右対称に２本の押圧部３２、３２’を有している点でのみ第１図で示した画鋲と異なるが、レバー操作に基づく画鋲の離脱機能は第１図のものと何等異なるところはない。
【０００７】
本発明の第３実施例を第５図より説明する。第５図は第１図と同様の機能を有しているが、画鋲本体１の頂面より針２が１本のみ突出した画鋲で、離脱に要する構成要素は第１図と何等異ならない。
【０００８】
本発明の第４実施例である二個の画鋲離脱用レバーを左右対称に形成した例について、第６図、第７図、第８図より説明する。前記第１実施例で本発明の技術思想について詳細に説明したように、左右対称に形成した回動部材の例においても全く同様の効果が奏されるものである。
第６図は本発明の第４実施例を示す図であり、図示するように、画鋲本体１の頂面から針２と２’が突出し、画鋲本体１の左右両側部に左右対称に形成した画鋲離脱用レバー３と３’を、両操作部３１と３１’が近付く方向に回動可能に取付けられている。この画鋲離脱用レバー３、３’は、壁や柱や掲示板等に取付けられた状態で画鋲本体１の頂面と実質的に平行な押圧部３２、３２’と、該押圧部３２、３２’に繋がり画鋲本体１の側面に沿ってのびる操作部３１、３１’で構成されるレバーであり、これは回転軸４、４’により画鋲本体１に対して回動自在に装着されている。
第７図および第８図は、本発明第４実施例の壁からの離脱方法について説明するための図であり、第７図は壁へ取付けられている状態を、また第８図はレバー操作で壁からの離脱がなされている状態をそれぞれ示す。
以上の構成を具備する本発明の画鋲では、前記実施例１と同様、画鋲離脱用レバー３と３’を、両操作部３１と３１’が近付く方向に操作することによって、壁や柱や掲示板等に取付けられた画鋲を極めて容易に離脱させることができる。
また、レバー操作で画鋲本体１と壁６との間には間隙Ｌが付与され、レバー操作で針２を壁６から完全に離脱させるには間隙Ｌを大きくすればよく、したがってレバー操作による回動量を大きくする配慮を払えばよい。
【０００９】
【発明の効果】
以上説明したように、本発明によれば、操作部３１を摘んで画鋲離脱用レバー３を回動することにより、この画鋲離脱用レバー３に設けられた押圧部３２にて壁６を押付けて、針を壁から離脱させることができる。したがって、この画鋲離脱用レバー３のテコ作動が針を引抜く力に代わるため、支点を支える必要なく指による摘み力によって、固定されていない掲示板等からもワンタッチで容易に安定して画鋲を離脱させることができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a thumbtack for attaching paper, a poster, a calendar, and the like to a wall, a pillar, a bulletin board, and the like.
[0002]
[Prior art]
As is well known, a conventional pushpin has a flat disk body and a needle protruding from the center thereof, and after attaching a paper, a poster, a calendar, or the like to a wall, a pillar, a bulletin board, or the like, a wall or a pillar is attached. When it is necessary to detach from a bulletin board or a bulletin board, the flat disc body of the thumbtack is grasped and detached.
However, conventional pushpins need to be pushed all the way to the base of the needle in order to securely attach paper, posters, calendars, etc.On the other hand, considerable force is required for the release, and conversely, If it is pushed in shallowly so that it can be easily removed, it has a problem that it comes off immediately with a slight influence.
Thus, in Japanese Utility Model Laid-Open No. 48-71939 and Japanese Utility Model Laid-Open No. 50-144743, there is known a thumbtack utilizing the function of a lever to facilitate removal. Japanese Utility Model Laid-Open No. 48-71939 is a thumbtack in which a part of the upper part of the thumbtack body is bent upward. Hold the head lightly and release it using the leverage action to raise the curved part upward. Japanese Utility Model Laid-Open No. 50-144743 discloses that a lever plate fitted into a concave groove at the top of a thumbtack main body uses a rod axis passing through the inside of the lever plate as a fulcrum, and the lever plate moves up and down in a seesaw manner. It is a thumbtack that works on, and when pulling out, raises the thumbtack body and the wall or bulletin board using a lever board to create a gap in advance, and then grip the thumbtack flat disk body Let go.
[0003]
[Problems to be solved by the invention]
However, the thumbtack of Japanese Utility Model Laid-Open No. 48-71939 needs to support the fulcrum by lightly pressing the thumb of the thumbtack when it is necessary to remove the thumbtack. When pulling out, raise the gap between the thumbtack main body and the wall or bulletin board using a lever board to make a gap in advance, and then pinch the flat disc body of the thumbtack and remove it, not one touch, or However, since both require the support to support the fulcrum when the power point is raised, there is a problem in stability when the thumbtack is detached from an unfixed bulletin board or the like.
SUMMARY OF THE INVENTION An object of the present invention is to provide a thumbtack that can securely attach paper, a poster, a calendar, and the like, and that can be easily detached with a single touch.
[0004]
[Means for Solving the Problems]
Therefore, the present invention proposes a thumbtack having a novel structure that replaces the above-mentioned known thumbtack. The feature of the thumbtack of the present invention is that the thumbtack main body having at least one needle protruding from the top surface. A peripheral portion of the surface, a portion that becomes a pressing portion substantially parallel to the same top surface in a state where it is attached to a wall, a pillar, a bulletin board, and the like, and an operating portion connected to the pressing portion and extending along the side surface of the thumbtack main body. Is rotatably mounted via a rotating shaft, so that the lever operation of the lever replaces the force of pulling out the needle, so that there is no need to support the fulcrum and the bulletin board is not fixed by the gripping force of the finger. It is also possible to easily and stably release the thumbtack with one touch from the like.
[0005]
【Example】
An example in which a single pushpin releasing lever according to the first embodiment of the present invention is formed will be described with reference to FIGS. 1, 2, and 3. FIG. FIG. 1 is a view showing a first embodiment of the present invention. As shown, needles 2 and 2 'protrude from the top surface of a thumbtack main body 1, and a thumbtack releasing lever 3 is provided between the needles 2 and 2'. Is mounted so as to be rotatable. The thumbtack releasing lever 3 is attached to a wall, a pillar, a bulletin board, or the like, and has a pressing portion 32 substantially parallel to the top surface of the thumbtack main body 1, and is connected to the pressing portion 32 along the side surface of the thumbtack main body 1. The lever is a substantially L-shaped lever composed of an extending operation part 31, which is rotatably mounted on the thumbtack main body 1 by a rotation shaft 4.
In the thumbtack of the present invention having the above-described configuration, the thumbtack attached to a wall, a pillar, a bulletin board, or the like can be detached very easily by operating the thumbtack detaching lever 3.
2 and 3 are views for explaining a method of detaching from a wall according to the first embodiment of the present invention. FIG. 2 shows a state of being attached to a wall, and FIG. 3 shows a lever operation. Indicates a state in which separation from the wall is performed.
As shown in FIG. 2, when the paper 5 is held on the wall 6 using the needle 2, the pressing portion 32 of the pushpin releasing lever 3 is parallel to the surface of the wall 6. Therefore, there is no inferiority to the mounting state of the known thumbtack.
When the thumbtack is to be detached from the wall 6, the operating portion 31 of the thumbtack releasing lever 3 may be pressed toward the thumbtack main body 1 as indicated by an arrow X.
FIG. 3 is a diagram showing a state immediately after the pressing is performed. As described above, since the thumbtack releasing lever 3 is rotatably attached to the thumbtack main body 1 by the rotating shaft 4, it is turned by the pressing force in the arrow X direction. Therefore, the pressing portion 32 rotates about the rotation shaft 4 as a fulcrum as shown in the figure. This rotation presses the surface of the wall 6. This pressing force acts as a force in the direction of detaching the thumbtack, and the thumbtack separates from the wall 6.
That is, a gap L is provided between the thumbtack main body 1 and the wall 6 by lever operation. In order to completely separate the needle 2 from the wall 6 by operating the lever, the gap L may be increased, and therefore, consideration should be given to increasing the amount of rotation by operating the lever.
As described above, the thumbtack of the present invention has been described by way of example, but it is not necessary to attach the thumbtack releasing lever 3 using only the rotating shaft.
[0006]

FIG. 4 is a diagram showing an example of a thumbtack according to the present invention to which a thumbtack releasing lever 3 of another shape is attached. As shown in the drawing, the needles 2 and 2 ′ protrude from the top surface of the thumbtack main body 1, and a thumbtack releasing lever 3 having pressing portions 32 and 32 ′ is attached to both left and right sides of the needles 2 and 2 ′. The pushpin release lever 3 is attached to a wall, a pillar, a bulletin board, or the like, and has pressing portions 32, 32 'substantially parallel to the top surface of the thumbtack main body 1, and is connected to the pressing portion and provided on the side surface of the thumbtack main body. The lever is substantially U-shaped because it is composed of an operating portion 31 extending along and has two pressing portions 32 and 32 'symmetrically. This is rotatably mounted on the thumbtack main body 1 by a rotating shaft 4. In the case of this structure, the thumbtack releasing lever 3 differs from the thumbtack shown in FIG. 1 only in that it has two pressing portions 32 and 32 ′ symmetrically in the left-right direction. The function of detaching the thumbtack is not different from that of FIG.
[0007]
A third embodiment of the present invention will be described with reference to FIG. FIG. 5 has the same function as FIG. 1, except that only one needle 2 protrudes from the top surface of the thumbtack main body 1, and the components required for detachment are not different from those of FIG.
[0008]
A fourth embodiment of the present invention, in which two thumbtack releasing levers are formed symmetrically, will be described with reference to FIGS. 6, 7, and 8. FIG. As described in detail in the technical idea of the present invention in the first embodiment, the same effect can be obtained even in the case of the rotating member formed symmetrically.
FIG. 6 is a view showing a fourth embodiment of the present invention. As shown, needles 2 and 2 ′ protrude from the top surface of the thumbtack main body 1 and are formed symmetrically on both left and right sides of the thumbtack main body 1. The thumbtack releasing levers 3 and 3 'are attached so as to be rotatable in a direction in which both the operation units 31 and 31' approach. The pushpin releasing levers 3 and 3 ′ are, when attached to a wall, a pillar, a bulletin board, or the like, pressed portions 32, 32 ′ substantially parallel to the top surface of the pushpin body 1, and the pressed portions 32, 32 ′. And a lever composed of operating portions 31 and 31 'extending along the side surface of the thumbtack main body 1, which is rotatably mounted on the thumbtack main body 1 by rotating shafts 4 and 4'.
7 and 8 are views for explaining a method of detaching from a wall according to a fourth embodiment of the present invention, wherein FIG. 7 shows a state of being attached to a wall, and FIG. Indicates a state in which separation from the wall is performed.
In the thumbtack of the present invention having the above configuration, similarly to the first embodiment, by operating the thumbtack releasing levers 3 and 3 ′ in a direction in which both the operation portions 31 and 31 ′ approach, the wall, the pillar or the bulletin board is operated. The thumbtack attached to the like can be detached very easily.
A gap L is provided between the thumbtack main body 1 and the wall 6 by lever operation, and the gap L may be increased to completely separate the needle 2 from the wall 6 by lever operation. Care should be taken to increase the momentum.
[0009]
【The invention's effect】
As described above, according to the present invention, the wall 6 is pressed by the pressing portion 32 provided on the thumbtack releasing lever 3 by pinching the operating portion 31 and rotating the thumbtack releasing lever 3. The needle can be released from the wall. Therefore, since the lever operation of the thumbtack releasing lever 3 replaces the force of pulling out the needle, it is not necessary to support the fulcrum, and the thumb can be easily and stably detached from an unfixed bulletin board or the like by one-touch by a finger pulling force. Can be done.
