Description
本発明は安全帯取付具に関する。 The present invention relates to a safety band fixture.
落下の危険性のある高い場所で作業を行う場合には安全帯の使用が義務付けられている。安全帯は、命綱としてのロープ部分と、そのロープ部分を安定支持物に固定するためのフック部と、墜落時に人体を保持するためのベルトとから構成されている。
従来、安全帯のロープ部分を安定支持物に固定する取付具は各種提案されている。例えば、図８に示す下記特許文献１には、安全帯を幅広Ｈ鋼、壁面突出部材などの工事部材（５２）に取り付ける挟持型の安全帯取付具（５３）が開示されている。
この安全帯取付具（５３）では略コ字形部材（５４）を工事部材（５２）に嵌めた後、略コ字形部材（５４）の上側水平部（５５）に螺着したボルト（５６）と、略コ字形部材（５４）の下側水平部（５７）との間に工事部材（５２）を挟み込み、ボルト（５６）の先端を工事部材（５２）の表面に強力に圧接させることによって略コ字形部材（５４）を工事部材（５２）に固定する構成としてある。
The use of a safety belt is obligatory when working in places where there is a high risk of falling. The safety belt is composed of a rope part as a lifeline, a hook part for fixing the rope part to a stable support, and a belt for holding a human body in the event of a crash.
Conventionally, various attachments for fixing a rope portion of a safety belt to a stable support have been proposed. For example,
In this safety band fixture (53), a bolt (56) screwed to the upper horizontal portion (55) of the substantially U-shaped member (54) after fitting the substantially U-shaped member (54) to the construction member (52). The construction member (52) is sandwiched between the lower horizontal portion (57) of the substantially U-shaped member (54), and the tip of the bolt (56) is strongly pressed against the surface of the construction member (52). The U-shaped member (54) is fixed to the construction member (52).
上記従来構成の安全帯取付具（５３）であれば、下記のような課題がある。
（Ａ）ボルト（５６）の先端と下側水平部（５７）によって工事部材（５２）を強く締め付ける構成なので、工事部材（５２）が幅広Ｈ鋼のように十分な強度を有するものでないと工事部材（５２）が破損して安全帯取付具（５３）として機能しないという課題がある。
（Ｂ）ボルト（５６）の先端と下側水平部（５７）を強く挟持する場合に、木材表面のように比較的軟質な材料で壁材が構成されている場合は、壁材の表面が著しく傷んでしまうという課題がある。
（Ｃ）安全帯取付具（５３）の取付強度はボルト（５６）の締め付け度合によって、大きく変化するので、ボルト（５６）の締め付けを十分に行わない場合は、安全帯取付具（５３）が工事部材（５２）から脱落してしまう可能性がある。
また、ボルト（５６）の締め付けを強固に行おうとしてもボルト（５６）の先端部の面積は小さいので、工事部材（５２）の表面の状態、例えば表面の傾きや錆があること等によって十分な固定が行いづらいこともある。
If it is the safety band fixture (53) of the said conventional structure, there exist the following subjects.
(A) Since the construction member (52) is strongly tightened by the front end of the bolt (56) and the lower horizontal portion (57), the construction member (52) must be sufficiently strong like wide H steel. There exists a subject that a member (52) is damaged and does not function as a safety belt fixture (53).
(B) When the tip of the bolt (56) and the lower horizontal portion (57) are strongly clamped and the wall material is made of a relatively soft material such as a wood surface, the surface of the wall material is There is a problem that it is severely damaged.
(C) Since the mounting strength of the safety band mounting tool (53) varies greatly depending on the tightening degree of the bolt (56), the safety band mounting tool (53) is used when the bolt (56) is not sufficiently tightened. There is a possibility of falling off the construction member (52).
Further, even if the bolt (56) is tightened firmly, the area of the tip of the bolt (56) is small, so that the surface state of the construction member (52), for example, the surface inclination or rust is sufficient. It may be difficult to fix.
（Ｄ）作業員の体重がボルト（５６）先端部に係る構成なので、ボルト（５６）の強度のみならず、垂直部（５９）、上側水平部（５５）及び下側水平部（５７）を含む略コ字形部材（５４）自体の高い強度が要求され、安全帯取付具（５３）の重量が大きくなり、製造価格が高くなってしまう課題がある。
本発明の目的は、簡単な構成で木質等の壁材に簡単かつ安全に取り付けることができる安全帯取付具を提供することを目的とする。
また、他の目的として、上記従来技術の各課題を解決することができる安全帯取付具を提供することにある。
上記に記載した以外の発明の課題、その解決手段及びその効果は、後述する明細書内の記載において詳しく説明する。
(D) Since the weight of the worker is related to the tip of the bolt (56), not only the strength of the bolt (56) but also the vertical portion (59), the upper horizontal portion (55), and the lower horizontal portion (57) The substantially U-shaped member (54) itself that is included is required to have high strength, and the weight of the safety band fixture (53) increases, resulting in an increase in manufacturing cost.

The first elastic member (8-1) to the third elastic member (8-3) are attached so as to avoid the two corners (26, 27) of the main body (4). The reason for this is that when the wall (5) is attached to the main body (4), the corner (26, 27) does not have the elastic member (8) and the upper surface (5A) of the wall (5) does not hit. Because it gets better.
弾性部材（８）の材料としては、特に限定されない。ある程度のクッション性を有し、摩擦抵抗が大きく耐久性のある材料、例えば、ゴム材のようなものが好ましい。
また、弾性部材（８）の内部空間（１３）側（図１参照）の表面には、摩擦抵抗を大きくする表面加工が施されている。そのような表面加工としては、例えば、エンボス加工（９）や、その他の摩擦抵抗を大きくする公知の加工が例示できる。
The material for the elastic member (8) is not particularly limited. A durable material having a certain degree of cushioning property and a large frictional resistance, such as a rubber material, is preferable.
Further, the surface of the elastic member (8) on the inner space (13) side (see FIG. 1) is subjected to surface processing for increasing the frictional resistance. Examples of such surface processing include embossing (9) and other known processing for increasing the frictional resistance.
＜取付け部（１０）＞
図１に示すように、第１の辺（１）の他端部（１ｂ）側には取付け部（１０）が形成してある。取付け部（１０）は安全帯のフック部（１１）（図６参照）を取り付けるための部材であれば足り、その具体的な形状・構成は限定されない。
図１に示す構成では、第１の辺（１）の他端部域に半円形突条（２１）を形成し、その内部に略半円形の開口（１２）を設けることで取付け部（１０）を構成した例が示してある。取付け部（１０）は第１の辺（１）の他端部（１ｂ）側に接するように設けられることが好ましい。これは、力の作用点を第１の辺（１）の他端部（１ｂ）に設けることで、第１の辺（１）の長さが第２の辺（２）の長さよりも大きい利点を享受できるようにするためである。
また、第１の辺（１）の外側面（１ｃ）に接するように取付け部（１０）を設けることで、力のかかる方向を第１の辺（１）に対して図５の力（２３）のように傾いた方向でなく、図５の力（２２）のように下方向に近づけた状態で使用することができる利点がある。
<Mounting part (10)>
As shown in FIG. 1, the attachment part (10) is formed in the other end part (1b) side of the 1st edge | side (1). The attachment portion (10) may be a member for attaching the hook portion (11) (see FIG. 6) of the safety belt, and its specific shape and configuration are not limited.
In the configuration shown in FIG. 1, a semicircular protrusion (21) is formed in the other end portion region of the first side (1), and a substantially semicircular opening (12) is provided therein, thereby attaching the mounting portion (10 ) Is shown. The attachment portion (10) is preferably provided so as to be in contact with the other end portion (1b) side of the first side (1). This is because the point of action of the force is provided at the other end (1b) of the first side (1) so that the length of the first side (1) is larger than the length of the second side (2). This is so that the benefits can be enjoyed.

固定部材（１４）は第１の辺（１）に設けられた場合は、第１の辺（１）に設けられた第１弾性部材（８−１）よりも壁材（５）側に突出して、壁材（５）に圧接することで安全帯取付具（２０）を壁材（５）に固定させる。
<Fixing member (14)>
As shown in FIGS. 1 and 5, the width of the substantially U-shaped internal space (13) is formed larger than the width of the wall material (5), but this is not possible when the main body (4) is loosely fitted. It is stable. Therefore, a fixing member (14) that can be fixed so as to fill a difference in the width in the depth direction (Y) of the wall material (5) and the internal space (13) is provided.
In the configuration shown in FIGS. 1 and 3, the fixing member (14) bulges a part of the width (on the left side in FIG. 3) on one side of the first side (1) outward, and the bulging portion ( 15), a female screw portion (16) is formed, and a bolt portion (18) having a hand-turned head portion (17) is screwed together. Then, the main body (4) can be fixed without being displaced from the wall (5) mainly in the depth direction (Y) by pressing the bolt (18) against the wall (5). It is.
When the fixing member (14) is provided on the first side (1), it protrudes closer to the wall material (5) than the first elastic member (8-1) provided on the first side (1). Then, the safety band fixture (20) is fixed to the wall material (5) by being pressed against the wall material (5).
本実施形態に係る固定部材（１４）のボルト部（１８）は、従来例に示した構成のように強力な締め付け力を与えるものではなく、壁材（５）に圧接する固定点を少なくとも一つ設ける機能を有するものである。
また、本実施形態に係る固定部材（１４）は、第１の辺（１）、第２の辺（２）、第３の辺（３）に設ける構成を除外するものではない。
The bolt portion (18) of the fixing member (14) according to the present embodiment does not give a strong tightening force unlike the configuration shown in the conventional example, and at least one fixing point that presses against the wall material (5) is provided. It has a function to provide one.
Further, the fixing member (14) according to the present embodiment does not exclude the configuration provided on the first side (1), the second side (2), and the third side (3).
＜コ字形の本体部（４）と壁材（５）との関係＞
図１に示すコ字形の本体部（４）が形成する内部空間（１３）の大きさは、取り付けようとする壁材（５）の奥行方向（Ｙ）の長さに対応して製造される。固定部材（１４）で固定できないほど壁材（５）の奥行方向（Ｙ）の長さが大きく違う壁材（５）には、それぞれその壁材（５）に対応した大きさの内部空間（１３）を有する安全帯取付具（２０）が用意される。
<Relationship between U-shaped body (4) and wall material (5)>
The size of the internal space (13) formed by the U-shaped main body (4) shown in FIG. 1 is manufactured corresponding to the length in the depth direction (Y) of the wall material (5) to be attached. . For the wall material (5) whose length in the depth direction (Y) of the wall material (5) is so different that it cannot be fixed by the fixing member (14), the internal space (in the size corresponding to the wall material (5)) ( A safety band fixture (20) having 13) is provided.
＜本構成を採用する利点の一例＞
本安全帯取付具（２０）は有利な特徴を有している。
第１の点は、略コ字形の本体部（４）を壁材（５）に上方から遊嵌させる構成であるから、本体部（４）は壁材（５）に対して回転するように動いて外れることはなく、結果的に、本体部（４）の各辺の面で安全帯にかかる力を分散しつつ受け止めることができる点である。
第２の点は、第１及び第２角部（２６・２７）を含んだ状態で、第１の辺（１）、第２の辺（２）、第３の辺（３）を繋ぐ一連一体の突条（７）が形成されているので、略コ字形の本体部（４）の変形を、簡単な構成で強力に抑制できる点である。
第３の点は、本体部（４）の内側に弾性部材（８）が設けられており、しかも弾性部材（８）の表面に摩擦抵抗を高くする表面加工が施されているので、固定部材（１４）に固定後も略コ字形の本体部（４）が壁材（５）からズレにくくなっている点である。
第４の点は、突条（７）に開口（１２）を設け、その開口（１２）を略半円形の開口（１２）として形成し、半円形の線側を第１の辺（１）に接して配置した点である。この構成とすることで、略円形の開口（１２）を設ける構成に比べてフック部（１１）の当接部（３０）（図７参照）をより壁材（５）に近づけることができ、取付の安定性を向上することができる。
<An example of the advantages of using this configuration>
The safety band fixture (20) has advantageous features.
The first point is a configuration in which the substantially U-shaped main body (4) is loosely fitted to the wall material (5) from above, so that the main body (4) rotates with respect to the wall material (5). As a result, the force applied to the safety belt can be received while being distributed on the surface of each side of the main body (4).
The second point is a series connecting the first side (1), the second side (2), and the third side (3) in a state including the first and second corners (26, 27). Since the integral protrusion (7) is formed, the deformation of the substantially U-shaped main body (4) can be strongly suppressed with a simple configuration.
The third point is that the elastic member (8) is provided inside the main body (4), and the surface of the elastic member (8) is subjected to surface processing for increasing the frictional resistance. Even after fixing to (14), the substantially U-shaped main body (4) is difficult to be displaced from the wall material (5).
The fourth point is that the protrusion (7) is provided with an opening (12), the opening (12) is formed as a substantially semicircular opening (12), and the semicircular line side is defined as the first side (1). It is the point arranged in contact with. By adopting this configuration, the contact portion (30) (see FIG. 7) of the hook portion (11) can be brought closer to the wall material (5) than the configuration in which the substantially circular opening (12) is provided. Mounting stability can be improved.
ここで、図５に示すように、真下方向の力（２２）がかかった場合を考えると、略コ字形の本体部（４）は略コ字形の突条（７）によってほとんど変形できないので、真下方向の力は第３の辺（３）、第２の辺（２）に伝わって、第３の辺（３）と第２の辺（２）を壁材（５）により圧接する方向に働くので、安全帯取付具（２０）は外れることがない。
さらに、図５において、作業者の壁材（５）から離れる方向の動きによって斜め方向の力（２３）がかかった場合でも、下方向の分力（２４）の作用は同じであり、また、壁材（５）の第１の辺（１）側の面において離れる方向に働く水平方向の分力（２５）は、第２の辺（２）の弾性部材（８−２）がより壁材（５）の壁面（５ｃ）に圧接する方向に力が働くことになる。つまり、作業者が大きく動いて、斜め方向の力がかかった場合でも、安全帯取付具（２０）が脱落する危険性を極めて低減することができる。
Here, as shown in FIG. 5, when considering a case where a downward force (22) is applied, the substantially U-shaped main body (4) can hardly be deformed by the approximately U-shaped protrusion (7). The downward force is transmitted to the third side (3) and the second side (2), and in the direction in which the third side (3) and the second side (2) are pressed by the wall material (5). Since it works, the safety band fixture (20) will not come off.
Further, in FIG. 5, even when an oblique force (23) is applied by the movement away from the worker's wall material (5), the action of the downward component force (24) is the same, The horizontal component force (25) acting in the direction away from the surface on the first side (1) side of the wall material (5) is more due to the elastic member (8-2) on the second side (2). A force is exerted in the direction in which it is pressed against the wall surface (5c) of (5). That is, even when the worker moves greatly and a force in an oblique direction is applied, the risk that the safety band attaching tool (20) will drop off can be greatly reduced.
また、図７に示すように、第１の辺（１）側の壁材（５）の角（２９）を考えた場合、第１の辺（１）が短い場合は、安全帯のフック（１１）の当接部（３０）が壁材（５）の面（５Ｂ）となす角度は角度（α１）となり、第１の辺（１）が長い場合は、その角度は角度（α２）となる。
図７から分かるように、α２＜α１であり、図５に示すように同じ大きさの水平方向の分力（２５）が当接部（３０）にかかった場合に、第１の辺（１）のモーメントは、第１の辺（１）が長い方が短い方に比べて大きくなるから、より外れにくくなる。
さらに、第１の辺（１）が第２の辺（２）よりも長いと、安全帯取付具（２０）を手で持って壁材（５）に取り付けるときに操作がしやすくなる利点もある。
本実施形態の構成であれば、従来例に示したボルトの先端で挟持する構成に比べて、力がかかればかかるほど、第３の辺（３）と第２の辺（２）に設けられた弾性部材（８−３），（８−２）が壁材（５）に圧接する方向に働くので、脱落防止の観点から好ましいことになる。
さらに、木材のような表面が比較的傷の付きやすい部材であっても、少なくとも第３の辺（３）と第２の辺（２）の２つの面の全面で受け止めるので、傷がつくことを大幅に抑制することができる。
In addition, as shown in FIG. 7, when the corner (29) of the wall material (5) on the first side (1) side is considered, if the first side (1) is short, a safety belt hook ( The angle formed by the contact portion (30) of 11) and the surface (5B) of the wall material (5) is the angle (α1), and when the first side (1) is long, the angle is the angle (α2). Become.
As can be seen from FIG. 7, when α2 <α1, and when the horizontal component force (25) of the same magnitude is applied to the contact portion (30) as shown in FIG. 5, the first side (1 ) Is larger when the first side (1) is longer than when the first side (1) is shorter.
Furthermore, if the first side (1) is longer than the second side (2), there is an advantage that it is easy to operate when holding the safety band attachment (20) by hand and attaching it to the wall material (5). is there.
If it is the structure of this embodiment, compared with the structure clamped with the front-end | tip of the volt | bolt shown in the prior art example, it will be provided in 3rd edge | side (3) and 2nd edge | side (2), so that more force is applied. Further, the elastic members (8-3) and (8-2) work in the direction in which they are pressed against the wall material (5), which is preferable from the viewpoint of preventing the dropout.
Furthermore, even if the surface such as wood is a member that is relatively easily scratched, it is received on the entire surface of at least the third side (3) and the second side (2), so that it is damaged. Can be greatly suppressed.
＜壁材（５）への安全帯取付具（２０）の取付作業＞
図１〜図６の構成において、上記構成の安全帯取付具（２０）の壁材（５）への取付作業の一例について簡単に説明する。
まず、図１に示す安全帯取付具（２０）を壁材（５）の上端にコ字形本体部（４）の内部空間（１３）を緩く嵌め込むように取り付ける。その後、固定部材（１４）が設けられた第１の辺（１）とは反対側の辺である第２の辺（２）を壁材（５）の面（５ｃ）に寄せるように本体部（４）を位置させる。
この状態で、固定部材（１４）の手回し頭部（１７）を回して、壁材（５）の外側壁面にボルト部（１８）の頭部を圧接させた状態にする（図５に示す状態）。この状態では、固定部材（１４）はコ字形本体部（４）と壁材（５）との隙間があることによるガタツキを防止する部材として機能することになる。
そして、図６に示すように、安全帯のフック部（１１）を取付け部（１０）の開口（１２）に嵌め込む。この状態で力をかけると、フック部（１１）の引っ張る力が取付け部（１０）に作用した場合には、ほぼ第１の辺（１）から下方に向かうように力がかかり、その力は第２の辺（２）及び第３の辺（３）によって壁材（５）のそれぞれの面で確実に受け止められる。
<Attachment work of safety band fixture (20) to wall material (5)>
In the structure of FIGS. 1-6, an example of the attachment operation | work to the wall material (5) of the safety band fixture (20) of the said structure is demonstrated easily.
First, the safety band attaching tool (20) shown in FIG. 1 is attached so that the inner space (13) of the U-shaped main body (4) is loosely fitted to the upper end of the wall material (5). After that, the main body portion so that the second side (2), which is the side opposite to the first side (1) provided with the fixing member (14), is brought close to the surface (5c) of the wall material (5). Position (4).
In this state, the hand-turned head (17) of the fixing member (14) is turned to bring the head of the bolt part (18) into pressure contact with the outer wall surface of the wall material (5) (state shown in FIG. 5). ). In this state, the fixing member (14) functions as a member that prevents rattling due to the gap between the U-shaped main body (4) and the wall material (5).
Then, as shown in FIG. 6, the hook portion (11) of the safety belt is fitted into the opening (12) of the attachment portion (10). When a force is applied in this state, when the pulling force of the hook portion (11) acts on the attachment portion (10), a force is applied to move downward from the first side (1). The second side (2) and the third side (3) are reliably received on the respective surfaces of the wall material (5).
