[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, respectively: 1(a) is a perspective view seen from the front, 1(b) is a perspective view seen from the rear, 2(a) is a side view, 2(b) is a front view, 2(c) is a rear view, and 2(d) is a bottom view. Note that the front view (2(b)) and the rear view (2(c)) do not show the driving member 12 (showing only the fitting member 11) for the sake of easy understanding of the configuration. Also, Fig. 5 is a schematic diagram showing the state in which a cable (wire rope) is inserted into the cable end clamp according to this embodiment (a conceptual diagram showing the positional relationship of each component when the driving member has not been driven (generating almost no fastening force)), and Fig. 5(a) is a schematic cross-sectional view taken along the longitudinal direction, and Fig. 5(b) is a schematic cross-sectional view taken perpendicular to the longitudinal direction. For ease of explanation, the front side of the driving member 12 along the rear side of the driving member 12 (the left side in FIG. 2(a)) is referred to as the "front surface," and the opposite side (the right side in FIG. 2(a) where the driving member 12 is inserted) is referred to as the "rear surface." 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 surface," and the opposite side (the upper side in FIG. 2(a)) is referred to as the "top surface."

[0019] As shown in FIG. 5(a), the cable end clamp 1 of this embodiment is used to eye the end of a cable such as a wire rope WR in order to hold the end of the cable. The rope retaining fitting 1 of this embodiment comprises: a fitting member 11 having a tubular body portion through which the rope is inserted; a driving member 12 having a wedge-shaped portion that is inserted into the tubular body portion of the fitting member 11 and abuts against the rope within the tubular body portion; a first side surface portion 111 provided on the rear side (a first side surface that is the side on which the driving member 12 of the tubular body is inserted) and a second side surface portion 112 provided on the front side (a second side surface that is the opposite side to the first side surface); a first rope retaining notch 1111 provided on the first side surface portion 111, which is a U-shaped notch that receives and inserts the rope, and has a notch depth that is deeper than the diameter of the rope; and a second rope retaining notch 1121 provided on the second side surface portion 112, which is a U-shaped notch that receives and inserts the rope. The wedge-shaped portion of the driving member 12 and the rope are inserted into the cylindrical portion of the fitting member 11, and as the driving member 12 is driven in (from the state shown in FIG. 5(a) to the left side of the figure), the pressure generated by the wedge shape of the driving member restrains the rope. The basic function and configuration are the same as those of the wedge clamp disclosed in Patent Document 1, so the following description 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 the first side surface portion 111 and the second side surface portion 112 having the first and second rope-retaining notches 1111, 1121 described below, improving the workability of the rope fastening operation and making the fastening more reliable. Furthermore, 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 comprising a first side portion 111 and a second side portion 112 having first and second cord retaining notches 1111, 1121 provided at positions facing the front and rear sides of the V-shaped groove.

[0021] The fitting member 11 has a tapered cylindrical body portion that restrains a driving member 12 and a rope such as a wire rope WR. As the driving member 12 and the rope enter the tapered internal space of the fitting member 11, a strong frictional force is generated between the respective components, thereby restraining the rope. To achieve this function, a V-shaped groove (a V-shaped groove on the cylindrical body portion) is formed on the inner surface of the fitting member 11's cylindrical body portion, configured to contact the rope on two sides. Because this V-shaped groove itself is similar to the wedge clamp disclosed in Patent Document 1, a description of the V-shaped groove itself will be omitted here. As described above, in the fitting member 11 of this embodiment, the cylindrical body portion is formed by bending (and welding) a cut or pressed plate material, and the V-shaped groove is formed by a V-shaped groove member 113 that is formed separately from the cylindrical body portion and disposed inside the cylindrical body portion.

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

[0023] The basic configuration of the cylindrical body portion of the fitting member 11 is that 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 surface 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 surface of the cylindrical body portion). The first side surface portion 111 is formed with a first rope body holding notch portion 1111, which is a U-shaped (inverted U-shaped) notch that receives and passes a rope body such as a wire rope WR. The first rope body holding notch portion 1111 of this embodiment has an engaging portion 11111 at an intermediate position of the notch depth, the notch width of which is narrower than the diameter of the rope body. As can be seen from FIG. 5(b), when the first wire rope WR is inserted deep into the first rope body holding notch portion 1111, the wire rope WR can be lightly engaged. 5B, the first rope member holding notch 1111 of this embodiment has a depth sufficient to receive two ropes, and a depth sufficient to receive at least the radius of the second rope (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 member holding notch 1111 and locked by the locking portion 11111, the wire rope WR is positioned within the V-shaped groove portion 1131 of the V-shaped groove member 113, as shown in FIG. 5B. In other words, "when the rope inserted into the cylindrical body portion is inserted deeper into the rope member holding notch on the first side surface than the position where the notch width is narrower than the diameter of the rope, the rope is positioned within 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 facilitate the insertion of the rope into the cylindrical body portion). The second side surface portion 112 is formed with a second rope-retaining notch portion 1121, which is a U-shaped (inverted U-shaped) notch that receives and inserts a rope such as a wire rope WR. The second side surface portion 112 is located opposite the front end surface of the V-shaped groove member 113 inside the cylindrical body portion, and is configured so that when the wire rope WR is inserted all the way into the second rope-retaining 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 cord-retaining notch 1121 is formed with a depth sufficient to receive the diameter of the cord or more, and like the first cord-retaining notch 1111, it is provided with a locking portion whose notch width is narrower than the diameter of the cord, but the present invention is not limited to this, and the second cord-retaining notch may be formed with a depth sufficient to receive the radius of the cord 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 cylindrical body, but as long as the second cord-retaining notch has holes formed therein through which two cords can be inserted, the second side surface portion may entirely cover the front side of the cylindrical body.

[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 driving member 12, for example, with a lever (tool such as a pliers) to make it movable (to release the fastening). They 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 the example shown here has windows 114 formed on both side surfaces, windows 114 may be formed on only one side surface or the bottom surface (or no windows 114 may be formed). Convex portions (engagement portions) 117 that protrude toward the inner surface are formed on the lower rear side of both side surfaces of the cylindrical body. The convex portions 117 engage with slide grooves 123 of the driving member 12, described below, to slidably engage the driving member 12 relative to the cylindrical body. The protrusion 117 also functions to enable rotation of the driving member 12 around the protrusion 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 engages one end of the cord to be eye-machined and holds the cord in the center in the width direction (left-right direction in FIG. 2( b)) (so that it is in an appropriate position relative to the V-groove of the driving member). The rear side of the bottom side of the cylindrical body of the fitting member 11 is formed with an opening 116, leaving a portion of the bottom surface of the cylindrical body open. This increases the rotation angle of the driving member 12 around the protrusion 117 as a 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, 4B, and 4C are diagrams showing the driving member 12, each showing a perspective view from the front top, a perspective view from the front bottom, and a side view. In side view, the driving member 12 has a wedge shape between its bottom surface 122 and its top surface (V-shaped groove 121). When this wedge-shaped portion is driven into the cylindrical body of the fitting member 11 together with the rope, pressure is generated, generating friction between the fitting member 11, the driving member 12, and the rope, thereby fastening the fitting member 11 to the rope. The driving member 12 has a V-shaped groove (driving member-side V-shaped groove) 121 formed on its top surface, which is configured to contact the rope on two sides. The V-shaped groove itself is similar to that of the wedge clamp disclosed in Patent Document 1, and therefore will not be described here. The driving member 12 has a cut portion 1211 formed at the upper portion 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 area 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 cut portion 1211 is formed in a planar shape approximately parallel to the bottom surface portion 122 as an example here, the present invention is not limited to this. Any cut portion may be used as long as 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] Slide grooves 123 are formed on both side surfaces of the driving member 12. The slide grooves 123 slidably engage with the protrusions 117 formed on the inner surface of the cylindrical body of the fitting member 11. The slide grooves 123 extend in the front-to-rear direction and are generally parallel to the bottom surface 122. The front side of the slide grooves 123 terminates near the front end of the driving member 12. Therefore, when the driving member 12 is slid rearward, the protrusions 117 of the cylindrical body are engaged with the front end of the slide grooves 123, preventing the driving member 12 from falling off. In this embodiment, the slide grooves 123 have a protrusion introduction port (engagement port) 1231 that opens on the bottom side of the driving member 12. The protrusions 117 can be introduced into or removed from the slide grooves 123 through the protrusion introduction port 1231, thereby enabling the driving member 12 to be attached to or detached from the fitting member 11.

[0029] 6A and 6B are explanatory diagrams illustrating the removal operation of the driving member 12 from the fitting member 11. FIG. 6A shows the state in which the driving member 12 is attached to the fitting member 11 (the convex portion 117 formed on the inner surface of the cylindrical body of the fitting member 11 is slidably engaged with the slide groove 123). When the driving member 12 is moved rearward, as described above, the slide groove 123 terminates at the front end, so the convex portion 117 is locked and cannot be moved back any further. In this state ( FIG. 6A ), rotating the driving member 12 around the convex portion 117 as a fulcrum results in the state shown in FIG. 6B . The opening 116 on the bottom surface of the cylindrical body allows the driving member 12 to be rotated widely. 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 releasing 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] A bulge 124 (a mountain-shaped portion within the slide groove) is formed within the slide groove 123, allowing the protrusion 117 to overcome it with little resistance. When the driving member 12 is slid in the driving direction from the state shown in FIG. 6( a), the protrusion 117 abuts against the bulge 124. Further sliding until the protrusion 117 overcomes the bulge 124 results in the state shown in FIG. 6( e). The state shown in FIG. 6( e) prevents the driving member 12 from rotating to remove it. The bulge 124 generates a certain resistance force against the driving member 12 sliding backward, thereby maintaining the state shown in FIG. 6( e). This further prevents the driving member 12 from accidentally falling off the fitting member 11.

[0031] As can be seen from the above, according to the rope fastening fitting 1 of this embodiment, the first rope fastening notch 1111 and the second rope fastening notch 1121 allow the driving member 12 to be driven in while the rope such as the wire rope WR is held in place (while the rope is positioned in the V-groove), which improves workability and facilitates proper fastening work, making it extremely user-friendly. With conventional rope fastening fittings, when attempting to fasten a thin wire rope, for example, 2 mm or less, the flexibility of the thin wire rope can cause the wire rope passed through the cylindrical body to twist, preventing it from being properly positioned in the V-groove. If the wire rope is not positioned properly in the V-groove, the appropriate fastening force cannot be obtained, so the wire rope needs to be positioned properly in the V-groove, but the rope fastener itself for fastening thin wire ropes of 2 mm or less is small, so driving the driving member while positioning the wire rope passed through the cylindrical body in the appropriate position (while holding it so that it does not slip) can be a cumbersome task.In contrast, with the rope fastener 1 of this embodiment, the driving member 12 can be driven while the rope is held by the first rope holding notch 1111 and the second rope holding notch 1121 (with the rope positioned in the V-groove), improving workability.

[0032] Furthermore, according to the rope 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 separately from this, so that 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 including a first side portion 111 and a second side portion 112 having first and second rope retaining notches 1111, 1121 provided at positions facing the front and rear sides of the cylindrical body portion.

[0033] While the present embodiment illustrates a small-sized cable anchor used for small-diameter wire ropes (e.g., wire ropes with a diameter of 2 mm or less), the present invention is not limited thereto. The concepts of the first side surface 111 and the second side surface 112 having the first and second cable-retaining notches 1111 and 1121 described above, as well as the concepts of the cylindrical body being formed by bending a plate and the V-groove being formed separately from the cylindrical body, can be applied to cable anchors of any size corresponding to cables of any thickness. While the present embodiment illustrates a cylindrical body formed by bending a plate, the present invention is not limited thereto. For example, the cylindrical body may be formed by joining multiple plate members. Furthermore, if precision and strength permit, the cylindrical body may be cast (in which case the V-groove and the first and second side surfaces having the first and second cable-retaining notches may 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 "the driving member is configured such that the rotation angle of the driving member is increased by cutting out a portion of the side (bottom) of the fitting member opposite the side of the driving member that contacts the cable." 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 concepts related to the first side portion 111 and the second side portion 112 having the first and second cable retention notches 1111, 1121 described above, the concept related to the tubular body being formed by bending a plate material, and the concept related to the V-shaped groove member being formed separately from the tubular body, and the like; each concept may be applied individually to the cable end clamp.

[0035] In this embodiment, the first rope member holding notch 1111 has a depth sufficient to accommodate the radius of the second rope member or more, but the first rope member holding notch may have a notch depth at least greater than the diameter of the rope member (a depth sufficient to accommodate the diameter of the first rope member or more), and may be formed to accommodate the diameter of the second rope member or more (i.e., a notch depth at least twice the diameter of the rope member). In addition, a "second locking portion having a notch width narrower than the diameter of the rope member" may be further provided to allow the second rope member to be lightly locked. The second rope member holding notch may also have a depth sufficient to accommodate the radius of the second rope member or to be formed to accommodate the diameter of the second rope member or more, and may additionally be provided with a locking portion that allows the second rope member to be lightly locked.

[0036] In this embodiment, an example is given in which there is both a first side portion 111 having a first cord body holding notch portion 1111 and a second side 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 portion having a first cord body holding notch portion (even if there is only a first side 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, although the embodiment exemplifies a case in which the driving member is generally composed of only a wedge-shaped portion and the fitting member is generally composed of only a cylindrical portion, the present invention is not limited to this. Any device may be used 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).
