[Figure 6] An explanatory diagram illustrating removal of the driving member DETAILED DESCRIPTION OF THE INVENTION

[0017] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Note that the following embodiments are merely examples of how the present invention can be realized, and are not intended to limit the scope of the present invention.

[0018] 1 and 2 are diagrams showing a cable end clamp according to an embodiment of the present invention, and are respectively Fig. 1(a): a perspective view seen from the front, Fig. 1(b): a perspective view seen from the rear, Fig. 2(a): a side view, Fig. 2(b): a front view, Fig. 2(c): a rear view, and Fig. 2(d): a bottom view. Note that Fig. 2(b) the front view and Fig. 2(c) the rear view are shown without the driving member 12 (only the fitting member 11) in order to clearly show the configuration. Also, Figure 5 is a schematic diagram showing the state in which a rope (wire rope) is inserted into the rope retaining fitting of this embodiment (a conceptual diagram showing the positional relationship of each component when the driving member has not been driven in (generating almost no fastening force)), where Figure 5(a) is a schematic cross-sectional view along the longitudinal direction, and Figure 5(b) is a schematic cross-sectional view perpendicular to the longitudinal direction. For ease of explanation, the front side of the driving member 12 along the rear side after driving (the left side in FIG. 2(a)) is referred to as the "front face," and the opposite side (the right side in FIG. 2(a), the side into which the driving member 12 is inserted) is referred to as the "rear face." Additionally, the side of the driving member 12 that comes into contact with the fitting member (the lower side in FIG. 2(a)) is referred to as the "bottom face," and the opposite side (the upper side in FIG. 2(a)) is referred to as the "top face."

[0019] As shown in FIG. 5(a), the cable end clamp 1 of this embodiment is used to form an eye at the end of a cable such as a wire rope WR in order to hold the end of the cable. The cable retaining fixture 1 of this embodiment is: a fitting member 11 having a cylindrical body portion through which a cord is inserted; a driving member (12) having a wedge-shaped portion inserted into the cylindrical body portion of the fitting member (11) and abutting against the cord body inside the cylindrical body portion; a first side surface portion 111 provided on the rear side (a first side surface that is the side where the driving member 12 of the cylindrical body portion is inserted), and a second side surface portion 112 provided on the front side (a second side surface that is the opposite side of the first side surface); a first cord holding notch 1111, which is a U-shaped notch provided in the first side surface portion 111 and through which the cord is received and passed, and has a notch depth deeper than the diameter of the cord; a second cord holding notch 1121, which is a U-shaped notch provided on the second side surface portion 112 and through which the cord is received and passed; It is equipped with: The wedge-shaped portion of the driving member 12 and the rope are inserted into the cylindrical portion of the fitting member 11, and the driving member 12 is driven in (driving the driving member 12 from the state shown in FIG. 5(a) to the left side of the figure), whereby the rope is restrained by the pressure generated by the wedge shape of the driving member. The basic function and the configuration therefor are the same as those of the wedge clamp disclosed in Patent Document 1, and therefore the following description thereof will be omitted or simplified.

[0020] As will be described in detail below, the rope end clamp 1 of this embodiment is a small fitting used for small-diameter ropes (for example, wire ropes with a diameter of 2 mm or less), and the rope is held in an appropriate position by a first side surface portion 111 and a second side surface portion 112 having first and second rope-retaining notches 1111, 1121 described below, improving the workability of the rope fastening operation and making the fastening more reliable. Also, in order to create structural parts such as the first and second rope-retaining notches 1111, 1121 with high precision, the cylindrical body portion of the fitting member 11 is formed by bending a cut or pressed plate material, and the V-shaped groove portion formed inside the cylindrical body portion is formed as a separate body. This makes it possible to precisely form a small engaging member 11 having a V-shaped groove as an internal structure and a first side portion 111 and a second side portion 112 with first and second cord body holding notches 1111, 1121 provided at positions facing the front and rear sides of the V-shaped groove.

[0021] The engaging member 11 has a cylindrical body portion formed in a tapered cylindrical shape and is used to restrain the driving member 12 and a rope such as a wire rope WR.When the driving member 12 and the rope enter the tapered internal space of the cylindrical body portion of the engaging member 11, a strong frictional force is generated between the respective components, thereby restraining the rope. In order to obtain an effective restraining force for the rope in this function, a V-shaped groove (a V-shaped groove on the cylindrical body side) configured to contact the rope on two sides is formed on the inner surface of the cylindrical body of the fitting member 11. This V-shaped groove itself is similar to the wedge clamp disclosed in Patent Document 1, so a description of the V-shaped groove itself will be omitted here. As described above, the fitting member 11 of this embodiment has a cylindrical body portion formed by bending (and welding) a cut or pressed plate material, and a V-shaped groove formed by a V-groove member 113 formed separately from the cylindrical body portion and arranged inside the cylindrical body portion.

[0022] FIG. 3 is a perspective view showing the V-groove member 113. As shown in FIG. The V-groove member 113 is a member having a V-shaped groove portion 1131, which is the above-mentioned "V-shaped groove," and is arranged so that the V-shaped groove portion 1131 faces downward on the inside of the upper surface of the cylindrical body portion of the fitting member 11. As a result, a V-shaped groove that contacts the cord body on two sides is formed on the inside of the upper surface of the cylindrical body portion. In this embodiment, the V-groove member 113 is fixed (welded) to the inside of the cylindrical body portion of the fitting member 11, but the present invention is not limited to this, and the V-groove member 113 may not be fixed (for example, it may be placed inside the cylindrical body portion each time). Furthermore, the fixing method is not limited to welding, and it may be fixed by adhesive or the like.

[0023] The cylindrical body portion of the fitting member 11 has a basic configuration in which it has both side surfaces, a top surface, and a bottom surface, and has a roughly rectangular cross-sectional shape in a cross section perpendicular to the driving direction, tapering toward the front. In addition, a first side surface portion 111 is provided on the rear side of the cylindrical body portion, and a second side surface portion 112 is provided on the front side.

[0024] The first side surface portion 111 is provided on the upper side of the rear side of the cylindrical body portion of the fitting member 11 (leaving the lower side open so that the driving member 12 can be inserted from the rear side of the cylindrical body portion). A first rope body holding notch 1111, which is a U-shaped (inverted U-shaped) notch that receives and passes a rope body such as a wire rope WR, is formed in the first side surface portion 111. The first rope body holding notch 1111 of this embodiment has a locking portion 11111 at the middle position of the notch depth, where the notch width is formed narrower than the diameter of the rope body, and as can be seen from Fig. 5(b), it is configured so that when the first wire rope WR is inserted deep into the first rope body holding notch 1111, the wire rope WR can be lightly locked. In addition, the first rope body holding notch 1111 of this embodiment has a depth sufficient to accommodate two rope bodies, as shown in Figure 5(b), and has a depth sufficient to accommodate at least the radius of the second rope body (wire rope WR). The first side surface portion 111 is located opposite the rear end surface of the V-shaped groove member 113 inside the cylindrical body portion, and is configured so that when the first wire rope WR is inserted deep into the first rope body holding notch portion 1111 and the wire rope WR is locked by the locking portion 11111, as shown in Fig. 5(b), the wire rope WR is positioned inside the V-shaped groove portion 1131 of the V-shaped groove member 113. In other words, "when the rope inserted into the cylindrical body portion is inserted deeper into the rope body holding notch portion on the first side surface than the position where the notch width is formed narrower than the diameter of the rope body, the rope is positioned inside the V-shaped groove on the cylindrical body portion side."

[0025] The second side surface portion 112 is provided on the upper side of the front side of the cylindrical body portion of the fitting member 11 (leaving the lower side open to allow for easier insertion of the cord into the cylindrical body portion). The second side surface portion 112 is formed with a second rope body holding notch portion 1121, which is a U-shaped (inverted U-shaped) notch for receiving and inserting a rope body such as a wire rope WR. The second side portion 112 is located opposite the front end surface of the V-shaped groove member 113 inside the tubular body portion, and is configured so that when the wire rope WR is inserted deep into the second rope body holding notch portion 1121, the wire rope WR is positioned within the V-shaped groove portion 1131 of the V-shaped groove member 113. In this embodiment, the second rope body holding notch 1121 is formed with a depth that can accommodate the diameter of the rope body or more, and like the first rope body holding notch 1111, it is provided with a locking portion whose notch width is formed narrower than the diameter of the rope body, but the present invention is not limited to this, and the second rope body holding notch may be formed with a depth that can accommodate the radius of the rope body or more. In addition, in this embodiment, the second side surface portion 112 covers approximately the upper half of the front side surface of the tubular body portion, but the second side surface portion may also cover the entire front side of the tubular body portion as long as a hole is formed as the second cord holding notch portion through which two cords can be inserted.

[0026] Windows (holes) 114 are formed on both side surfaces of the cylindrical body of the fitting member 11. The windows 114 are holes for prying the driven-in member 12 with, for example, a lever (a tool such as a peg) to make it movable (to release the fastening), and can also be used as windows for checking the fastening state of the rope (the state of the driving member 12 and the rope inside the cylindrical body). Note that, while an example in which the windows 114 are formed on both side surfaces is shown here, the window 114 may be formed on only one of the side surfaces or on the bottom surface (or no window 114 may be provided). On the lower rear side of both side surfaces of the cylindrical body, there are formed convex portions (engagement portions) 117 that protrude toward the inner surface. The convex portions 117 engage with slide grooves 123 of the driving member 12, which will be described below, to slidably lock the driving member 12 relative to the cylindrical body. The convex portions 117 also function to enable the driving member 12 to rotate around the convex portions 117 as a fulcrum. A third cord-retaining notch 115 is formed on the front side of the bottom surface of the cylindrical body of the fitting member 11. As shown in Fig. 5(a), the third cord-retaining notch 115 locks one side of the cord to be eye-machined and holds the cord so that it is centered in the width direction (left-right direction in Fig. 2(b)) (so that it is in an appropriate position with respect to the V-shaped groove of the driving member). The rear side of the bottom surface of the cylindrical body of the fitting member 11 is formed with an opening 116, which opens up part of the bottom surface of the cylindrical body, thereby increasing the rotation angle of the driving member 12 with the protrusion 117 as the fulcrum. As described above, in the fitting member 11 of this embodiment, both side surfaces, the top surface, and the bottom surface of the cylindrical body portion of the fitting member 11, as well as the first side surface portion 111 and the second side surface portion 112, are integrally formed by cutting or pressing a single plate (stainless steel plate), and the both side surface portions and the top surface and the bottom surface portions of this single plate are each bent to form a cylindrical shape, and the joint portions for forming the cylindrical shape are welded (and the first side surface portion 111 and the second side surface portion 112 are bent), thereby forming the cylindrical body portion, and various portions such as the window 114 and the protrusion 117 are also formed during the cutting or pressing process.

[0027] 4A and 4B are diagrams showing the driving member 12, with FIG. 4A being a perspective view seen from the front top side, FIG. 4B being a perspective view seen from the front bottom side, and FIG. 4C being a side view. When viewed from the side, the driving member 12 has a wedge shape between the bottom surface 122 and the top surface (V-shaped groove 121), and the pressure generated when this wedge-shaped portion is driven into the inside of the tubular body portion of the fitting member 11 together with the rope body generates frictional forces between the fitting member 11, the driving member 12 and the rope body, thereby fastening it to the rope body. A V-shaped groove (driving member-side V-shaped groove) 121 configured to contact the rope body on two sides is formed on the upper surface of the driving member 12. The V-shaped groove itself provided in this wedge-shaped member is also similar to the wedge clamp disclosed in Patent Document 1, so a description of the V-shaped groove itself will be omitted here. The driving member 12 has a cut portion 1211 formed at the upper part of its rear end so that the driving member-side V-shaped groove 121 is absent or shallow. The cut portion 1211 is formed so that the cut portion 1211 is approximately parallel to the bottom surface portion 122 in the range of the upper surface of the driving member 12 facing the first side surface portion 111. This prevents the driving member 12 from interfering with the first side surface portion 111 even as the driving of the driving member 12 progresses (even as the driving member 12 moves upward relative to the fitting member 11). Note that, while the example shown here uses a cut portion 1211 formed in a flat shape approximately parallel to the bottom surface portion 122, the present invention is not limited to this. Any cut portion may be formed so that the driving member 12 does not interfere with the first side surface portion even as the driving of the driving member progresses (even as the driving member moves upward relative to the fitting member).

[0028] On both side surfaces of the driving member 12, slide grooves 123 are formed which slidably engage with the protrusions 117 formed on the inner surface of the cylindrical body of the fitting member 11. The slide groove 123 is formed to extend in the front-rear direction and to be substantially parallel to the bottom surface portion 122 . The front side of the slide groove 123 terminates near the front end of the driving member 12, and therefore, when the driving member 12 is slid rearward, the convex portion 117 of the cylindrical body portion is engaged at the front end portion of the slide groove 123, thereby preventing the driving member 12 from falling off. The slide groove 123 of this embodiment has a convex portion introduction port (engagement portion introduction port) 1231 that opens on the bottom side of the driving member 12. The convex portion 117 can be introduced into or removed from the slide groove 123 through the convex portion introduction port 1231, thereby making the driving member 12 detachable from the fitting member 11.

[0029] FIG. 6 is an explanatory diagram illustrating the operation of removing the driving member 12 from the fitting member 11. Figure 6(a) shows the state in which the driving member 12 is attached to the fitting member 11 (the state in which the protrusion 117 formed on the inner surface side of the cylindrical body portion of the fitting member 11 and the slide groove 123 are slidably engaged). When the driving member 12 is moved rearward, as described above, the slide groove 123 terminates at the front end, so the protrusion 117 is locked and the driving member 12 cannot move back any further. In this state (FIG. 6(a)), when the driving member 12 is rotated around the protrusion 117 as a fulcrum, the state shown in FIG. 6(b) is reached. The opening 116 on the bottom surface of the cylindrical body allows the driving member 12 to be rotated a large distance. Next, as shown in Figures 6(b) and (c), by sliding the driving member 12 diagonally upward, the convex portion 117 can be guided into the convex portion introduction port 1231, and by removing the convex portion 117 from the slide groove 123 through the convex portion introduction port 1231, the driving member 12 can be removed as shown in Figure 6(d). The driving member 12 can be attached to the fitting member 11 by reversing the above procedure. As can be seen from the above, the driving member 12 can be attached to and detached from the fitting member 11 easily and efficiently, and the driving member 12 can be prevented from accidentally falling off the fitting member 11.

[0030] Within the slide groove 123, a bulge 124 (a mountain-shaped portion within the slide groove) is formed so that the protrusion 117 can climb over it with little resistance. When the driving member 12 is slid in the driving direction from the state shown in Figure 6(a), the convex portion 117 comes into contact with the bulge portion 124, and when the driving member 12 is slid further until the convex portion 117 overcomes the bulge portion 124, the state shown in Figure 6(e) is reached. 6(e) is a state in which the driving member 12 cannot be rotated to remove it, and the bulge 124 functions to maintain the state of FIG. 6(e) by generating a certain resistance force against the rearward sliding of the driving member 12. This further prevents the driving member 12 from accidentally falling off the fitting member 11.

[0031] As can be understood from the above, according to the rope retaining fitting 1 of this embodiment, the first rope retaining notch 1111 and the second rope retaining notch 1121 allow the driving member 12 to be driven in while the rope such as a wire rope WR is held in place (with the rope positioned within the V-shaped groove), which improves workability and makes it easier to perform appropriate fastening work, making it very easy to use. When attempting to fasten a thin wire rope of, for example, 2 mm or less with a conventional cable fastener, the wire rope passed through the cylindrical body may twist due to the flexibility of the thin wire rope, resulting in an issue where the wire rope is not properly positioned within the V-groove. If the wire rope is not properly positioned within the V-groove, the appropriate fastening force cannot be obtained, so the wire rope needs to be properly positioned within the V-groove. However, since the cable fastener itself for fastening a thin wire rope of 2 mm or less is small, it can be a cumbersome task to drive the driving member while properly positioning the wire rope passed through the cylindrical body (while holding it down to prevent it from slipping). In contrast, with the rope retaining fitting 1 of this embodiment, the driving member 12 can be driven in while the rope is held in place by the first rope holding notch 1111 and the second rope holding notch 1121 (with the rope positioned within the V-shaped groove), thereby improving workability.

[0032] Furthermore, according to the cable retaining fitting 1 of this embodiment, the cylindrical body portion of the engaging member 11 is formed by bending a cut or pressed plate material, and the V-shaped groove portion formed inside the cylindrical body portion is formed as a separate body from this. As a result, a small engaging member 11 can be formed with high precision, having the V-shaped groove portion as an internal structure of the cylindrical body portion and having a first side portion 111 and a second side portion 112 with first and second cable retaining notches 1111, 1121 provided at positions facing the front and rear sides of the cylindrical body portion.

[0033] In this embodiment, a small rope fastener is used as an example for a small diameter wire rope (for example, a wire rope with a diameter of 2 mm or less), but the present invention is not limited to this, and the concepts relating to the first side portion 111 and the second side portion 112 having the first and second rope retaining notches 1111, 1121 described above, as well as the concepts relating to the tubular body portion being formed by bending a plate material and the V-shaped groove member being formed separately from the tubular body portion, can be applied to a rope fastener of any size that can be used for a rope of any thickness. Furthermore, in this embodiment, the cylindrical body is formed by bending a plate material, but the present invention is not limited to this, and may be formed, for example, by joining a plurality of plate members. Furthermore, if precision and strength allow, the cylindrical body may be cast (in which case, the V-shaped groove member and the first and second side surfaces having the first and second cord holding notches may also be integrally formed).

[0034] As can be understood from the above description, the cable end clamp 1 of this embodiment is configured such that "the driving member is detachably attached to the fitting member by forming an engagement portion inlet (protrusion inlet) in the slide groove, which allows the engagement portion (protrusion) to be introduced into and removed from the slide groove by rotating the driving member relative to the fitting member," and also that "a portion of the side (bottom) of the fitting member opposite the side of the driving member that contacts the cable is cut out, thereby increasing the rotation angle of the driving member." These and other concepts related to the attachment and detachment structure of the driving member to the fitting member are not limited to being implemented together (simultaneously) with the above-described concepts related to the first side portion 111 and second side portion 112 having first and second cable retention notches 1111, 1121, the fact that the tubular body is formed by bending a plate material, and the fact that the V-shaped groove member is formed separately from the tubular body, and the like, and each concept may be applied individually to the cable end clamp.

[0035] In this embodiment, the first cord-retaining notch 1111 has a depth that can accommodate at least the radius of the second cord, but the first cord-retaining notch may have a notch depth that is at least deeper than the diameter of the cord (having a depth that can accommodate at least the diameter of the first cord), and may be formed to be able to accommodate at least the diameter of the second cord (i.e., the notch depth is at least twice the diameter of the cord). In addition, a "second locking portion whose notch width is formed narrower than the diameter of the cord" may be further provided to enable the second cord to be lightly locked. The second rope holding notch may also be deep enough to accommodate at least the radius of the second rope, or may be formed to accommodate at least the diameter of the second rope, and in addition, may be provided with a locking portion that allows the second rope to be lightly locked.

[0036] In this embodiment, an example is given in which there is both a first side surface portion 111 having a first cord body holding notch portion 1111 and a second side surface portion 112 having a second cord body holding notch portion 1121, but the present invention is not limited to this, and it is also possible to have only a first side surface portion having a first cord body holding notch portion (even if there is only a first side surface portion having a first cord body holding notch portion, it is possible to obtain a certain effect regarding the functional effects described above).

[0037] Furthermore, in the embodiment of the rope retaining fitting 1, the V-shaped groove that contacts the rope on two sides prevents slippage between the rope and the V-shaped groove by setting the angle of the two sides to a predetermined angle, as described in Patent Document 1, and while this is very preferable, it is not essential for the application of the present invention.

[0038] Additionally, in the embodiment, the driving member is generally composed of only a wedge-shaped portion, and the fitting member is generally composed of only a cylindrical portion, but the present invention is not limited to this. Anything can be provided as long as it includes a driving member having a wedge-shaped portion and a fitting member that fits into the driving member to restrain the rope by pressure generated by the wedge shape of the driving member (each of these components may additionally have other functions or structural parts).
