Description

本発明は、着脱が簡単確実な留め具に関するものである。  The present invention relates to a fastener that can be easily attached and detached.

留め具は衣料や小物それに靴や鞄類、また産業用にも各種のものが使用されている。しかし、留めたり外したりするのに両手を使わなければならなかったり、片手で出来ても留める力が弱かったり、また必要以上と思われる力で押したり引いたりせねばならないことがある。  Various kinds of fasteners are used for clothing, accessories, shoes and bags, and for industrial use. However, it may be necessary to use both hands to fasten or remove, and even with one hand, the force to fasten may be weak, or it may have to be pushed or pulled with a force that seems more than necessary.

後述の特許文献に開示されているクリップは特定用途のものであるが、外すときはドライバー等のマイナス部分を取外溝（１９）に差し込み梃子の原理で頭部（２１）を介して軸体（２０）を引き上げてグロメット（１０）のフランジ部（１２）から引き離さねばならず、着脱を頻繁にせねばならぬ用途では面倒である。
特開２００４−３１６８５６号公報（段落「００４１」〜「００４２」、図８） The clip disclosed in the patent document to be described later is for a specific application. When removing the clip, a minus part such as a screwdriver is inserted into the outer groove (19) and the shaft body via the head (21) in the principle of the lever. (20) must be pulled up and pulled away from the flange portion (12) of the grommet (10), which is troublesome in applications where frequent attachment / detachment is required.
JP 2004-316856 A (paragraphs “0041” to “0042”, FIG. 8)

解決しようとする問題点は、留め具の着脱を片手だけで容易に出来ない、または片手だけで着脱が出来ても留める力が弱かったする点である。  The problem to be solved is that the fastener cannot be easily attached / detached with one hand, or the fastening force is weak even if it can be attached / detached with only one hand.

弾性板（３）の両端の各々を凸部（２）側面の両開口部から同時に内外側に入ったり出たりさせ片端のみが遅れないようにするため、凸部（２）の上下中心軸線上に貫通する穴内面を上下にスライドする中子（４）の中心軸線上に弾性板（３）の中心がくるように取り付ける。中子（４）上部を下方に押せば弾性板（３）の中央部が下方に撓み両端間の直線長さが短くなり凹部（１）の開口部上部の狭まっている箇所を通過でき、窪んだ箇所で元の平らな状態に戻り両端間の直線長さが長くなるので留まり、逆に留まっている状態からタグ（６）を介し中子（４）を引き上げれば弾性板（３）中央部が上方に撓み外れる構成で着脱さすことを特徴とする。  In order to prevent both ends of the elastic plate (3) from entering and exiting the inner and outer sides at the same time from both openings on the side surface of the convex portion (2) so that only one end is not delayed, the upper and lower central axes of the convex portion (2) The elastic plate (3) is attached so that the center of the elastic plate (3) comes on the center axis of the core (4) that slides up and down on the inner surface of the hole penetrating through the hole. If the upper part of the core (4) is pushed downward, the central part of the elastic plate (3) bends downward, the straight line length between both ends is shortened, and it can pass through the narrowed part of the upper part of the opening of the concave part (1). If the core (4) is pulled up through the tag (6), the elastic plate (3) is centered. It is characterized in that the part is attached and detached in a configuration that bends upward.

本発明の留め具は、中子（４）を凹部（１）内部方向に押せば、中子（４）に取り付けられている弾性板（３）は下方に撓み凹部（１）上部の狭まっている開口部を通り抜けられ凹部（１）の窪み内で元の平らな状態に戻るので留まり、留まっている状態からタグ（６）を介し中子（４）を引き上げれば弾性板（３）が上方に撓み外れるので、片手でも押して留まり引いて外せるというように着脱が容易にできる利点がある。  In the fastener of the present invention, when the core (4) is pushed toward the inside of the recess (1), the elastic plate (3) attached to the core (4) is bent downward and the upper part of the recess (1) is narrowed. If the core (4) is pulled up through the tag (6) from the stayed state, the elastic plate (3) is pulled back. Since it bends upward, there is an advantage that it can be easily attached and detached, such that it can be pushed with one hand, stuck and pulled off.

着脱を簡単確実に行えるという目的を、高さをあまり必要としない構成部品で実現した。  The purpose of easy attachment and detachment is realized with components that do not require much height.

図１は、本発明の１実施例として、留め具の留める前の状態を断面図で、各構成部品を立体図で示しており、凹部（１）においてその上部開口部の内部側面周囲に窪みを設け、凸部（２）においてその中心縦方向に貫通する穴をあけ中子（４）が上下にスライドできるように、かつ横方向にも開口部を設け弾性板（３）が左右に動けるようにし、中子（４）においても横方向に山形の面が上下方向で互いに向き合うような開口部を設け、かつその中心縦方向にリベット形状の軸体（５）を通す穴を貫通させる。
組付けは凸部（２）と中子（４）の側面開口部を合わせて弾性板（３）を通してから、中子（４）と弾性板（３）の中心穴を合わせ軸体（５）を通した後、軸体（５）の下部を打ち広げて中子（４）から抜けないようにして、且つ軸体（５）の頭部に中子（４）を引っ張り上げやすいように弾性体よりなるタグ（６）を取り付ける。FIG. 1 is a cross-sectional view showing a state before a fastener is fastened as an embodiment of the present invention, and each component is shown in a three-dimensional view. In the concave portion (1), a recess is formed around the inner side surface of the upper opening. And a hole penetrating in the longitudinal direction of the center of the convex portion (2), so that the core (4) can slide up and down, and an opening portion is also provided in the lateral direction so that the elastic plate (3) can move left and right. Thus, the core (4) is also provided with openings such that the chevron surfaces face each other in the vertical direction in the lateral direction, and the hole through which the rivet-shaped shaft body (5) passes is formed in the central vertical direction.
Assemble the convex part (2) and the side opening of the core (4) through the elastic plate (3), and then align the center holes of the core (4) and elastic plate (3) to obtain the shaft (5). After passing, the lower part of the shaft body (5) is spread out so as not to come out of the core (4), and the core (4) is elastic so that it can be easily pulled up to the head of the shaft body (5). Attach tag (6) consisting of body.

図２は、留め具の留まる直前の状態を示した断面図である。タグ（６）をつまんで凸部（２）先端を凹部（１）開口部に近づけ中子（４）を凹部（１）内方向に押すと平らな弾性板（３）の中程が下方に押し曲げられ左右方向直線での長さが短くなり、弾性板（３）の両端は凸部（２）側面の開口部の内側に引っ込み凹部（１）上部の狭まった開口部を通り越し凹部（１）内の側面窪み内に達する。  FIG. 2 is a cross-sectional view showing a state immediately before the fastener is retained. When the tag (6) is pinched and the tip of the convex part (2) is brought close to the opening of the concave part (1) and the core (4) is pushed inward of the concave part (1), the middle of the flat elastic plate (3) is lowered downward. The both ends of the elastic plate (3) are retracted inside the opening on the side surface of the protrusion (2) and passed through the narrowed opening on the upper part of the recess (1). ) Reach inside the side depression.

図３は、留め具が留まっている状態を示した断面図である。 弾性板（３）の両端が凹部（１）の側面窪み内で元の伸びた平らな形状となって長さが凹部（１）上部の開口部直径より長くなり留まった状態となる。  FIG. 3 is a cross-sectional view showing a state in which the fastener remains. Both ends of the elastic plate (3) become the original flat shape in the side recess of the recess (1), and the length becomes longer than the diameter of the opening at the top of the recess (1) and stays.

図４は、留め具の外れる直前の状態を示した断面図である。タグ（６）を介して中子（４）を上方に引っ張れば弾性板（３）の中程が上方に撓み左右方向直線での長さが短くなり、弾性板（３）の両端は凹部（１）側面の窪みから凹部（１）上部の狭まった開口部を通り抜けられ外れる。 弾性板（３）の両端付近はテーパをつけ、凹部（１）上部の開口部と凸部（２）側面の開口部とで挟まれても、弾性板（３）の中程が引き上げられ内側に引っ張られると抜けやすくしている。  FIG. 4 is a cross-sectional view showing a state immediately before the fastener is removed. If the core (4) is pulled upward through the tag (6), the middle of the elastic plate (3) is bent upward, and the length in the straight line in the left-right direction is shortened, and both ends of the elastic plate (3) are recessed ( 1) It passes through the narrow opening at the top of the recess (1) from the depression on the side surface and comes off. Near both ends of the elastic plate (3) is tapered, and even if it is sandwiched between the opening at the top of the recess (1) and the opening at the side of the projection (2), the middle of the elastic plate (3) is pulled up and inside It is easy to come off when pulled.

図５は、留め具に外そうとする負荷がかかった状態を示した断面図である。タグ（６）を介し中子（４）を上方に引っ張り外そうとしない限り、凸部（２）を取り付けている被取付部材Ａ（７）を凹部（１）を取り付けている被取付部材Ｂ（８）から引き外そうとする力が加わっても、凹部（１）上部の狭まっている開口部と凸部（２）側面の開口部とで弾性板（３）の両端は各々挟まれ、その狭い隙間を通り抜けられないので外れない。このように、中子（４）を押せば留まり、逆にタグ（６）を介し中子（４）を引き上げれば外れるように着脱を容易確実にする効果がある。  FIG. 5 is a cross-sectional view showing a state in which a load to be removed is applied to the fastener. Unless the core (4) is pulled upward via the tag (6), the mounted member A (7) to which the convex portion (2) is attached is attached to the mounted member B to which the concave portion (1) is attached. Even if a force to pull off from (8) is applied, both ends of the elastic plate (3) are sandwiched between the narrowed opening of the upper part of the concave part (1) and the opening part of the convex part (2), I can't go through the narrow gap, so it won't come off. In this way, there is an effect that it can be easily attached and detached so that it can be stopped by pushing the core (4) and conversely removed by pulling up the core (4) via the tag (6).

図６の実施例は、十字形の弾性板Ａ（３Ａ）を中子Ａ（４Ａ）と当て部（４ｂ）との間に入れ、これらの中心線上に揃えて軸体（５）を通してから軸体（５）の下端の溝部を外側に打ち広げて当て部（４ｂ）が抜け落ちないようする、それを凸下部（２Ｂ）の上に開口部位置と十字形の弾性板Ａ（３Ａ）の各先端部分を合うように置き凸上部（２Ａ）を上からかぶせ圧入する、またその接合部の強度が足りなければスポット溶接により補強し一体化することによって、４先端部の４箇所で着脱することになるので、長方形の弾性板（３）での両先端部２箇所に比べ係合状態がより安定する。この他、３先端や５先端等の複数の先端を有するものを使用する構成も可能である。  In the embodiment of FIG. 6, a cross-shaped elastic plate A (3A) is inserted between the core A (4A) and the abutting portion (4b), aligned on the center line thereof, and passed through the shaft body (5) before the shaft. The groove (5b) at the lower end of the body (5) is spread outward so that the abutting part (4b) does not fall off. The upper part of the convex part (2B) is positioned on the opening part and each of the cross-shaped elastic plates A (3A). Place the convex upper part (2A) from above and press fit so that the tip part fits, and if the strength of the joint is not enough, reinforce and integrate by spot welding to attach and detach at four places on the four tip part Therefore, the engagement state is more stable than the two end portions of the rectangular elastic plate (3). In addition, a configuration using a plurality of tips such as three tips and five tips is also possible.

図７の実施例は、被取付部材Ｂ（８）が硬質の丈夫な材料でできていて、その厚さが凸部（２）の開口部から弾性板（３）両端の出入りを妨げない範囲以内のものなら、凹部（１）開口部と同じ直径の穴（９）を被取付部材Ｂ（８）にあけ、凹部（１）を被取付部材Ｂ（８）に取り付けずに、凸部（２）を直接その穴（９）に挿入して留めることもできる。
それに軸体Ａ（５Ａ）にはタグ（６）を取り付けなくても、軸体Ａ（５Ａ）の頭部を直接指または工具でつまみ引き上げられるように頭部の下方をへこませている。In the embodiment of FIG. 7, the mounted member B (8) is made of a hard and strong material, and the thickness does not hinder the entrance and exit of the elastic plate (3) from the opening of the convex portion (2). If it is within, the hole (9) having the same diameter as the opening of the recess (1) is made in the attached member B (8), and the recess (1) is not attached to the attached member B (8). 2) can also be inserted directly into the hole (9) and fastened.
In addition, the shaft A (5A) is recessed below the head so that the head of the shaft A (5A) can be picked up directly with a finger or a tool without attaching a tag (6).

押し引きにより片手でも簡単確実に着脱ができ、手先の不自由な障害者や片手で作業せねばならない際にも使え、また強い留める力を必要とする用途にも適用できる。  It can be easily attached and detached with one hand by pushing and pulling, and can be used for handicapped persons with disabilities and when they have to work with one hand, and can also be applied to applications that require strong fastening force.
