前記従来例は、支持基枠（支持基板）に対し支持受を回転させて組付ける構成を採るので、該支持受にケーブルなどの荷重が不均衡に負荷されると容易に回転してケーブル受支状態が不安定になる虞があり、このため、前記の回転を防ぐために該支持受を近接して配するなどの特別な工夫を必要とし、結局の処、必要に応じた、支持基枠に対する支持受の着脱に煩雑な操作を必要とする。 The conventional example employs a structure in which a support support is rotated and assembled to a support base frame (support substrate). Therefore, when a load such as a cable is applied to the support support in an unbalanced manner, the support support frame (supporting substrate) rotates easily. The support state may become unstable. For this reason, special measures such as arranging the support receivers close to each other to prevent the rotation described above are necessary. A complicated operation is required for attaching and detaching the support receiver.

本発明は、斯様な従来例の欠点に着目し、支持基枠に対して支持受を安定的に組付けられ、しかも、着脱に際してもその操作を円滑に行うことのできるケーブル受金具を提供することを目的として創案したものである。 The present invention pays attention to the disadvantages of such conventional examples, and provides a cable bracket in which a support receiver can be stably assembled to a support base frame, and the operation can be smoothly performed even during attachment / detachment. It was created for the purpose of doing.

実施例のケーブル受金具は、支持基枠１と該支持基枠１に適宜組付けて用いる支持受２とで構成する。 The cable bracket of the embodiment includes a support base frame 1 and a support receiver 2 that is used by being appropriately assembled to the support base frame 1.

支持基枠１は、上下方向に沿う両端を背面側方向に折り曲げて補強部片３ａを設けた基板３の相対する両端に、基板３の背面側方向にＬ字屈曲状にした止着部片４，４を設けて構成したもので、前記基板３には前記支持受２の組付け部５を縦方向に並設し、該組付け部５の適宜のものに前記支持受２を組み付けてケーブルｃをこれに懸架、受支させるようにしてある。 The support base frame 1 is a fastening part piece which is bent in an L shape in the back side direction of the substrate 3 at opposite ends of the substrate 3 provided with the reinforcing part 3a by bending both ends along the vertical direction in the back side direction. 4 and 4, and the substrate 3 is provided with an assembly portion 5 of the support receiver 2 arranged side by side in the vertical direction, and the support receiver 2 is assembled to an appropriate one of the assembly portions 5. The cable c is suspended and supported on the cable c.

組付け部５は、基板３の縦方向に沿う中央に設けた、ほぼＴ字状の係止孔６と、該係止孔６の直下に基板３の一部を背面方向に切り起こして設けた、上端側を自由端とした傾斜状の規制部片７および該規制部片７と重なり合う通し孔１５と、該通し孔１５の両側にして前記基板１に設けた縦長の受止孔８，８並びにばね９（ステンレス板で構成してある）とで構成し、ばね９は、ほぼコの字状の平板体で成り、しかも、左右の上端部を前記基板３の背面に熔接、止着して下端側の自由端部９ａの中央部を前記規制部片７と前記通し孔１５（基板３）との間に嵌挿し、しかも、左右両側部で前記受止孔８の上部側を閉塞したものである。 The assembling portion 5 is provided in a substantially T-shaped locking hole 6 provided in the center along the vertical direction of the substrate 3, and a part of the substrate 3 is cut and raised in the back direction immediately below the locking hole 6. In addition, an inclined restricting piece 7 having an upper end side as a free end, a through hole 15 overlapping with the restricting piece 7, and a vertically long receiving hole 8 provided in the substrate 1 on both sides of the through hole 15, 8 and a spring 9 (consisting of a stainless steel plate). The spring 9 is formed of a substantially U-shaped flat plate, and the left and right upper ends are welded and fixed to the back surface of the substrate 3. the central portion of the lower side of the free end portion 9a fitted in between said regulating piece 7 through-holes 15 (substrate 3), moreover, closes the upper side of the receiving locking hole 8 at the right and left side portions It is what.

支持受２は、支持基枠１と同様に金属板を屈曲して形成したもので、先後に長い長方形状の受部片１０ａの両側に側部片１０ｂ，１０ｂを相対設して構成した主体枠１０の前記受部片１０ａの先端に起立状にして設けた、ケーブルｃ用の落下防止片１１を具備する一方、該受部片１０ａの後端すなわち基端には先部１２ａと頸部１２ｂで成る、ほぼＴ字状の係止部片１２を突設し、この係止部片１２の基端縁（前記頸部１２ｂ側の）と基端縁を同面上に位置させた掛止部片１３を前記側部片１０ｂの後端すなわち基端に突設して構成したもので、掛止部片１３は先部１３ａと掛止部１３ｂとで成る鉤状体で成るものである。 The support receiver 2 is formed by bending a metal plate in the same manner as the support base frame 1, and is a main body constituted by providing side pieces 10 b and 10 b relative to both sides of a long rectangular receiver piece 10 a. The frame 10 includes a fall prevention piece 11 for the cable c, which is provided upright at the distal end of the receiving piece 10a of the frame 10. On the rear end, that is, the base end of the receiving piece 10a, a front portion 12a and a neck portion A substantially T-shaped locking piece 12 made of 12b is projected, and the base end edge (on the neck 12b side) and the base end edge of the locking piece 12 are located on the same surface. The stop piece 13 is formed by protruding from the rear end, that is, the base end of the side piece 10b, and the hook piece 13 is formed of a bowl-shaped body composed of a tip portion 13a and a hook portion 13b. is there.

なお、前記係止部片１２は、前記の通り、先部１２ａと頸部１２ｂとで成るＴ字状を成すのもであるが、その先部１２ａは、支持基枠１の基板３側に設けた係止孔６の、上部側の幅広部６ａより小径で、下部側の幅狭部６ｂより大径と成し、頸部１２ｂを前記係止孔６の幅狭部６ｂより小径と成し、従って、係止部片１２は、係止孔６に幅広部６ａにおいて挿通させ、係止孔６に沿って降下させて頸部１２ｂを幅狭部６ｂに係合させることにより、先部１２ａの両端が幅狭部６ｂの両縁に係止して支持受２の支持基枠１との組付け状態を保持するのである。また、この係止部片１２より下方にして支持受２の基端に設けた前記掛止部片１３は、縦長の前記先部１３ａを、縦長の前記掛止孔８の縦径より縦幅を小さく（短く）し、従って、前記掛止孔８に挿通させて降下させると、前記掛止部１３ｂが掛止孔８の下縁に掛止するのである。 As described above, the locking piece 12 has a T-shape composed of the tip portion 12a and the neck portion 12b, and the tip portion 12a is formed on the substrate 3 side of the support base frame 1. The provided locking hole 6 has a smaller diameter than the upper wide portion 6 a and a larger diameter than the lower narrow portion 6 b, and the neck portion 12 b has a smaller diameter than the narrow portion 6 b of the locking hole 6. Accordingly, the locking piece 12 is inserted into the locking hole 6 at the wide portion 6a and lowered along the locking hole 6 to engage the neck portion 12b with the narrow portion 6b. Both ends of 12a are locked to both edges of the narrow portion 6b to hold the assembled state of the support receiver 2 with the support base frame 1. In addition, the hooking piece 13 provided at the base end of the support receiver 2 below the locking piece 12 has a vertically long tip portion 13 a that is longer than the vertical diameter of the vertically long hooking hole 8. Therefore, when the height is made smaller (shorter), and is lowered by being inserted into the latching hole 8, the latching portion 13 b is latched on the lower edge of the latching hole 8.

しかして、例えば、隧道などの壁面ｗに突設した、上下一対のアンカーボルトｂに、該アンカーボルトｂを前記止着部片４に設けた透孔１４において貫通させて組合わせ、透孔１４より突出する該アンカーボルトｂの先端に固定ナットｎを螺合、締付けることにより支持基枠１は、前記アンカーボルトｂを突設した、隧道壁面ｗの適所に、基板３と壁面ｗ間において間隙ａを存して固定される。 Thus, for example, a pair of upper and lower anchor bolts b projecting from a wall surface w such as a tunnel are combined by passing the anchor bolts b through the through holes 14 provided in the fastening part piece 4. By fixing and fixing a fixing nut n to the tip of the anchor bolt b that protrudes further, the support base frame 1 has a gap between the substrate 3 and the wall surface w at an appropriate position on the side wall surface w where the anchor bolt b is projected. a is fixed.

この支持基枠１の基板３に上下方向にして並設した前記組付け部５，…の全部又は適宜の一部のものに、支持受２を組付けることにより実施例支持金具の使用状態を得ることができるのである。 The mounting state of the embodiment support bracket can be changed by assembling the support receiver 2 to all or an appropriate part of the assembly parts 5,... Arranged side by side on the substrate 3 of the support base frame 1 in the vertical direction. You can get it.

そして、支持受２を基板３（支持基枠１）に組付ける際、支持受２の係止部片１２と掛止部片１３を、基板３側の係止孔６と掛止孔８に一致させて押圧すると、掛止部片１３の先部１３ａは、基板３の背面側において掛止孔８の上部を閉じていたばね片９の自由端部９ａを、ばね付勢に抗して押圧して基板３前面側から背面側へ後退させ、この後退と同時に係止部片１２の先部１２ａも係止孔６の上側の大径部６ａを通じて基板３前面側から後退し、係止部片１２と掛止部片１３の基端と同面上に存する、支持受２の主体枠１０の基端が基板３の前面に接触位置に至った時点で、支持受２を押下させると、係止部片１２の頸部１２ｂは係止孔６の幅狭部６ｂに係合する一方、掛止部片１３はばね片９の自由端部９ａより下方に降下して掛止孔８の下部に降下係合し、ばね片自由端部９ａは掛止部片１３の頸部１３ｂの直上位置にばね作用により移動し、掛止部片１３の掛止孔８上方への移動を規制する（妨害する）のである。 When the support receiver 2 is assembled to the substrate 3 (support base frame 1), the engaging piece 12 and the engaging piece 13 of the supporting receiver 2 are connected to the engaging hole 6 and the engaging hole 8 on the substrate 3 side. When pressed in conformity, the tip 13a of the latching piece 13 presses the free end 9a of the spring piece 9 that closed the upper part of the latching hole 8 on the back side of the substrate 3 against the spring bias. Then, the front part 12a of the locking part 12 is retracted from the front side of the board 3 through the large diameter part 6a on the upper side of the locking hole 6 simultaneously with the backward movement from the front side of the board 3 to the back side. It lies on one 12 and multiplying the base end of the stopper piece 13 and the same on the surface, when the base end of the main frame 10 of the support receiving 2 reaches the contact position on the front surface of the substrate 3, when the user presses the support receiving 2, The neck portion 12b of the locking portion piece 12 engages with the narrow portion 6b of the locking hole 6, while the locking portion piece 13 descends below the free end portion 9a of the spring piece 9 and the locking hole. The spring piece free end portion 9a moves to a position directly above the neck portion 13b of the latching piece 13 by a spring action, and the movement of the latching piece 13 above the latching hole 8 is restricted. Do (disturb).

この組付け状態においてケーブルｃを支持受２（主体枠１０）上に懸架、受支させると、係止片１２の係止孔６、掛止片１３の掛止孔８それぞれに対する組付け関係によって支持受２に荷重が負荷しても支持受２は支持基枠１に対する組付け状態を確実に保たれ、ケーブルｃの懸架状態を維持できる。 When the cable c is suspended and supported on the support receiver 2 (main frame 10) in this assembled state, depending on the assembly relationship with respect to the locking hole 6 of the locking piece 12 and the locking hole 8 of the locking piece 13 respectively. Even if a load is applied to the support receiver 2, the support receiver 2 is reliably maintained in the assembled state with respect to the support base frame 1, and the suspended state of the cable c can be maintained.

そして規制部片７の前方側にして基板３に設けた通し孔１５を通じて前規制部片７と基板３との間に存するばね片９の自由端部９ａを押圧して後退させると、自由端部９ａは弾性変形して掛止部片１３上から後退し（このときの後退は、基板３と壁面ｗとが成す間隙ａ幅内において、かつ、規制部片７の存在によって制約を受ける）、この後退操作後、当該支持受２を上昇させると、ばね片９による規制が解除されたため、係止部片１２は係止孔６に、掛止部片１３は掛止孔８にそれぞれ沿って上昇し、係止部片１２には係止孔６の幅広部６ａ位置に、掛止部片１３の先部１３の先部１３ａは掛止孔８と一致する位置にそれぞれ至り、この状態で支持受２を前方へ引くことにより、支持受２の支持基枠１からの取り外しができるのである。 When the free end portion 9a of the spring piece 9 existing between the front restricting piece 7 and the substrate 3 is pressed and retracted through the through hole 15 provided in the substrate 3 on the front side of the restricting piece 7, the free end The portion 9a is elastically deformed and retreats from the hooking piece 13 (the retreat at this time is limited within the width a formed by the substrate 3 and the wall surface w and is restricted by the presence of the restricting piece 7). When the support receiver 2 is raised after the retraction operation, the restriction by the spring piece 9 is released, so that the locking part piece 12 extends along the locking hole 6 and the locking part piece 13 extends along the locking hole 8 respectively. And the locking part piece 12 reaches the position of the wide part 6a of the locking hole 6, and the tip part 13a of the tip part 13 of the locking part piece 13 reaches the position corresponding to the locking hole 8, respectively. The support receiver 2 can be detached from the support base frame 1 by pulling the support receiver 2 forward.
