[Configuration] The present invention is an electrically-driven slide buckle comprising a body part for traction in the fastening direction of a line member such as a chain. The body part constitutes a pair of cylindrical structures A that consists of a cylinder 10 and a cylinder 20 and that can be extended and retracted. The cylindrical structures constitute a screwing advancement / retraction mechanism B that includes a female screw hole 12 which is provided at the bottom part of the cylinder 10 at one side and a screwable shaft 30 which is represented by a long bolt and which has an outer screw part passing through the outer end and the inside of the cylinder 20 at the other side and having the tip reaching the female screw hole of the cylinder at the other side, and that allows the pair of cylinders to be extended and retracted.

Description

Electric slide buckle

[0001] The present invention relates to an electric slide buckle that replaces a turnbuckle, and more specifically, to an electric slide buckle that consists of a pair of cylindrical bodies, and a drive mechanism that slides them in the tightening direction is a screw-engagement forward / backward mechanism consisting of a female screw hole body provided in one of the cylindrical bodies and a screw-engagement shaft body that passes through the other cylindrical body that screws into the female screw hole body, and can be driven by a manual electric drill or a remotely controlled electric drive mechanism.

[0002] Formwork for pouring concrete in reinforced concrete structures is held in place by horizontal and vertical frame members to prevent it from shifting position or being deformed by the pressure of the fluidized concrete during pouring. Furthermore, the frame members are restrained by tension frame members and tension chains or other reinforcing members to prevent it from shifting position even when subjected to vibrations and pressure during concrete pouring. Furthermore, during transport by ship, containers being transported are tied down with wire ropes or the like without slack to prevent them from shifting position. The tension of these reinforcing chains and wire ropes is adjusted by tensioning devices such as turnbuckles to prevent slack.

[0003] This type of turnbuckle has a pair of threaded shanks with hooks or other fastening parts at the ends of a rotating buckle that forms the body, one with a right-handed thread and the other with a left-handed thread, which are screwed into a central rotating buckle, and the buckle is rotated about its axis with a manual wrench to bring the hook positions of the threaded shanks at both ends closer together in the tightening direction. While this turnbuckle has the advantage of being able to increase the length over which the hooks at both ends can be pulled, it has the problem that if the pulling length is long, the number of turns required around the axis of the central buckle increases, making tension adjustment time-consuming. Furthermore, when there is little slack in the reinforcing material, the body of the turnbuckle and the reinforcing material such as a chain are parallel and close together, which poses a structural problem: it is difficult to turn them with a wrench.

[0004] Therefore, a tightening device has been proposed that can be easily attached to the middle of a tensioned reinforcing bar with little slack and easily tightened. The device includes a threaded rod with a hook or other engaging portion formed at one end and a cylindrical body with a second engaging portion attached to the side at the other end. The tip of the threaded rod protrudes from the other end of the cylindrical body, and a nut is threaded onto the threaded rod. By tightening the nut, the first and second engaging portions of the shaft are brought closer together, thereby adjusting the tension for connecting to a chain, wire, or the like (Patent Document 1). However, because the tip of the threaded rod protrudes outside the nut through the nut, an electric drill cannot be used to rotate the nut around its axis, and a wrench perpendicular to the nut is required. Furthermore, because the traction line connecting the pair of hooks or other engaging portions is tilted away from the axis of the buckle, the pulling force on the pair of engaging portions is directly applied to the threaded rod shaft as bending stress, leading to bending or damage to the threaded rod shaft. This structural defect is present.

[0005] Patent No. 5004144

[0006] Therefore, the object of the present invention is to provide an electric slide buckle that allows the tightening operation of a pair of locking parts by rotating the turnbuckle to be performed using an electric tool such as an impact drill, rather than a wrench that is perpendicular to a muscle such as a chain.

[0007] To achieve the above object, the inventors conducted extensive research and discovered that if the body of a buckle, which tightens a chain via a pair of locking portions, is constructed from a pair of cylindrical bodies, with a female threaded hole inserted into one cylindrical body and a threaded shaft inserted into the other cylindrical body, and these are threaded together to form a screw-advance / retreat structure by rotation around an axis, the pair of cylindrical bodies can be given the function of a turnbuckle body, and this led to the completion of the present invention. Specifically, if the body of a turnbuckle is constructed as a pair of cylindrical body structures A, with a female threaded hole inserted into one cylindrical body and a threaded shaft, such as a long bolt, inserted into the other cylindrical body and threaded together to form a screw-advance / retreat structure B within the cylindrical bodies, the heads exposed from the cylindrical bodies can be rotated around the axis by an electric motor, thereby expanding and contracting the body consisting of the pair of cylindrical bodies. It was discovered that preferably, if the pair of cylindrical bodies are ultimately assembled as a double-cylinder structure, bending or damage to the threaded cylindrical body can be prevented. That is, the present invention provides a tightening buckle that includes a pair of first and second locking portions such as hooks that hook onto and lock onto a towed material such as a separating chain, and a trunk portion that slides the pair of locking portions from the separated position in the tightening direction to pull the towed material, The body portion comprises a cylindrical body structure A of a pair of first and second cylindrical bodies, each having a locking portion and sliding along a common axis to expand and contract, and a drive mechanism B for expanding and contracting the first and second cylindrical bodies along the common axis, which comprises a threaded hole body with a female thread housed in one of the cylindrical body portions and a screw-type shaft body rotatably inserted and guided through the other cylindrical body portion from the outer end to the other end, forming a screw structure in which the tip of the screw-type shaft body is screwed into the screw hole body of the other cylindrical body to connect them, and by rotating the head of the screw-type shaft exposed from the outer end of the cylindrical body with an electric drill or the like, the tip of the screw-type shaft is screwed into the other cylindrical body via the screw hole body, and the pair of first and second cylindrical bodies are slid from the separated position in the tightening direction to pull the pair of locking portions.

[0008] According to the present invention, the rotational movement of a conventional turnbuckle around its axis is changed to a buckle consisting of a pair of cylindrical bodies, one of which has a female screw hole and the other has a threaded shaft that screws into the female screw hole, and the pair of cylindrical bodies are slid by the rotational movement of the threaded shaft to tighten the buckle, so that the tightening operation can be performed with an electric drill. This is much easier than rotating a turnbuckle with a wrench and contributes to reducing the work time.

[0009] Furthermore, if an electric drive mechanism is provided on the head exposed from the outer end of the threaded shaft, which is rotatably inserted from one outer end of the first and second cylindrical bodies to the other, it can be remotely controlled by wireless means (Figure 14).This is a groundbreaking innovation that ensures safety when tightening the buckle at high altitudes.

[0010] When one of the first and second cylindrical bodies is inserted into the other to form a double cylindrical body, the bending moment of the traction force does not act directly on the threaded shaft, resulting in excellent durability. Even if the traction force applied to the pair of locking parts becomes large, it is absorbed by the inner and outer cylindrical bodies, so the drive mechanism installed inside is not directly subjected to torsion and will not malfunction even with long-term use.

[0011] At least one of the pair of locking portions provided on the first and second cylindrical bodies is provided on the side of the cylindrical body, and when the traction line connecting the locking portions of the first and second cylindrical bodies intersects with the axis of the sliding direction of the first and second cylindrical bodies at an intersection angle α, a traction force acts with the intersection point of the axis and the traction line as a fulcrum, thereby increasing the traction force (Figure 11).

[0012] In the fastening device of the present invention, the body that drives the pair of locking parts has locking parts at its ends, and is made up of a pair of cylinders of a length adopted according to the fastening distance of the reinforcing bars, one of which is the inner cylinder 10 and the other the outer cylinder 20, and the inner cylinder is fitted entirely together so that it can slide axially relative to the outer cylinder but cannot rotate about its axis relative to the outer cylinder, forming an expandable inner and outer double cylinder structure A, which has excellent durability against the bending moment of traction. The pair of cylinders may be abutted together, or may be partially fitted together.

[0013] In the present invention, it is preferable to configure the traction line P connecting the locking portions 11, 21 formed on the pair of cylindrical bodies 10, 20 so that it intersects with the cylindrical body axis L at an angle α near the center of the axis, and so that the stress when the pair of locking portions 11, 21 pulls a reinforcing material such as a chain is symmetrical with respect to the cylindrical body axis L and is offset, in order to improve the traction force; and it is also preferable from an operational standpoint that the threaded shaft, which is made of a long bolt or the like and inserted into the outer cylindrical body from the bottom, is provided with a locking ring on the inside of the bottom of the outer cylindrical body to prevent it from coming off.

[0014] Furthermore, the locking portions 11, 21 formed on the pair of cylinders are located on opposite sides of the barrel, in a point-symmetrical fashion with respect to the cylinder axis L, and the traction line P connecting the locking portions 11, 21 intersects with the cylinder axis L at an angle α at a fulcrum in the center of the axis. When a reinforcing material such as a chain is pulled by the pair of locking portions, the stress is symmetrical with respect to the cylinder axis and therefore offsets. As a result, the expandable inner and outer double-cylinder structure is not damaged, and the traction force increases according to the principle of leverage, with the intersection of the traction line P and the axis L as the fulcrum (the angle α of the traction line P with respect to the cylinder axis L is larger in Figure 5 than in Figure 3 (the intersection angle α2 in Figure 5 is larger than the intersection angle α1 in Figure 3), and the traction force increases due to the rotational movement around the intersection of the traction line P and the axis L as the fulcrum). Furthermore, if the threaded shaft, such as a long bolt inserted into the outer cylindrical body from the bottom, is provided with a locking ring on the inside of the bottom of the outer cylindrical body, the operation of hooking the chain onto the reinforcing bar becomes easier.

[0019] FIG. 4 is an explanatory cross-sectional view showing the principle of a fourth embodiment of the present invention, in which a first small-diameter cylindrical body (storage cylindrical body) and a second large-diameter cylindrical body (guide cylindrical body) are provided with a first hook and a second hook, respectively, a third net and a second nut are provided as female threaded holes in the middle and butt end of the first cylindrical body, a first long bolt is inserted as a threaded shaft from the end opposite the butt end of the first cylindrical body in the butt direction to the butt end, and the tip of the first screw shaft is threaded into the third nut in the middle, while a second long bolt is inserted as a threaded shaft from the end opposite the butt end of the second cylindrical body in the butt direction to the butt end, and the tip of the second screw shaft is threaded into the second nut, and then the first long bolt and the second long bolt are rotated via the exposed heads of one or both of them, thereby covering the storage cylindrical body with the guide cylindrical body and forming a double-cylinder structure.

[0021] 7 to 13 show preferred embodiments of the present invention. The electric drill-driven turnbuckle of the present invention is a fastening device having a pair of engaging portions such as hooks that are hooked onto reinforcing material such as a chain, and a body that pulls the pair of engaging portions in the direction of fastening the reinforcing material such as the chain, and is composed of an expandable body A that is fitted with a pair of long cylindrical bodies 10, 20 of different diameters to form an inner and outer double cylindrical structure, and a screw forward / backward driving mechanism B that has a shaft 30 that expands and contracts the pair of cylindrical bodies 10, 20 along the axis.

[0022] The body A of the cylindrical structure is made up of a pair of cylindrical bodies 10, 20, and uses a square steel pipe with a 10 mm side and a 2 mm plate thickness, and another square steel pipe with a 14 mm side and a 2 mm plate thickness, and comes in two or more lengths, long and short, depending on the application of the reinforcing material such as chain or wire rope. Here, there are prepared ones with a total length of 0.5 to 1 meter using a short inner and outer cylinder, and ones with a total length of 1.0 to 1.5 meters using a long inner and outer cylinder, where the distance between the pair of locking parts 11 and 21 is short.

[0023] One of the pair of cylindrical bodies 10, 20 is used as the inner cylindrical body 10, and the other is used as the outer cylindrical body 20. The inner cylindrical body 10 is fitted into the outer cylindrical body 20 with a cross section that is slidable in the axial direction extending in the longitudinal direction but does not rotate around the axis, thereby forming an expandable cylindrical structure A. Here, large and small rectangular pipes with square cross sections are used, but a pair of cylindrical bodies with oval cross sections may also be used. Alternatively, one or more radially protruding linear bodies extending in the longitudinal direction may be formed on the outer surface of the inner cylindrical body 10, while grooves with a concave cross section that fit into the linear bodies may be provided on the inner surface of the outer cylindrical body 20 so as to extend in the longitudinal direction. In short, it is preferable that the rotation around the axis of the threaded shaft 30 that threads into the inner cylindrical body 10 does not cause the outer cylindrical body 20 to rotate around the axis.

[0024] Figures 9(a) and 9(b) show the slide buckle of the present invention in its extended and fully retracted states. The bolt head exposed from the bottom of the outer cylindrical body is rotated around its axis from the fully extended state shown in Figure 9(a) to the fully retracted state shown in Figure 9(b) via an internal screw-advance / retraction drive mechanism B (not shown). Figure 10 shows the tightening operation using this extension / retraction motion. Figure 10(a) shows the tightening operation of loose ropes R1 and R2 using the slide buckle SB of the present invention. One hook portion 11 of the fully extended slide buckle SB is hooked onto rope R1, while the other hook portion 21 is hooked onto rope R2. Then, the exposed head portion 31 of the long bolt exposed from the bottom of the outer cylindrical body 20 is rotated around the axis of the threaded shaft by an electric motor ED1, such as an impact drill. With conventional turnbuckles, it was necessary to rotate the buckle that constitutes the body with a wrench perpendicular to it, but with the present invention, the tip of an impact drill is placed parallel to the rope and the exposed bolt head 31 of the long bolt 30 is rotated to thread the external threaded portion 30a of the long bolt 30 into the screw hole portion 12 at the bottom of the inner cylinder, thereby tightening the pair of ropes R1 and R2 as shown in Figure 4(b).

[0025] In a preferred embodiment of the electric slide buckle of the present invention, a cylindrical structure A consisting of an inner cylindrical body 10 and an outer cylindrical body 20 has a hook portion 11 provided at the tip of the inner cylindrical body 10 and a hook portion 21 provided at the bottom end of the outer cylindrical body 20 arranged symmetrically with respect to an axis L extending in the longitudinal direction of the cylindrical structure A, and a traction line P formed by the pair of hook portions 11, 21 intersects with the axis L at the center of the axial direction of the cylindrical structure A at an intersection angle of α1 (FIG. 9). Therefore, the locking portions 11, 21 formed on the pair of cylindrical bodies 10, 20 are positioned on opposite sides in a point-symmetrical manner with respect to the cylindrical axis L, so that stresses when a reinforcing material such as a chain is pulled by the pair of locking portions are symmetrical with respect to the cylindrical axis L and are offset.

[0026] Figure 11 shows a preferred second embodiment, in which the hook portion 11 of the inner cylindrical body 10 is moved to the opposite side from the position shown in Figure 9 to form a hook portion 11'. The traction line P formed by the hook portion 11' and the hook portion 21 intersects with the axis L at an intersection angle α2 larger than α1. Because the intersection angle is larger than in the case of Figure 9, the traction force applied to the pair of hook portions acts on the double cylindrical structure A with the intersection point of the traction line P and the axis L as the fulcrum, and acts to rotate it. Therefore, it has been found that the traction force acts more easily according to the principle of a lever with the intersection point as the fulcrum.

[0027] Figure 12 shows a preferred third embodiment, in which cap portions 10b, 20b at the top and bottom of the inner and outer cylindrical bodies 10, 20 are separated from the barrel portions 10a, 20a, and hook portions 11, 12 are welded to the cap portions 10a, 10b so that they protrude laterally to form a strong structure, which is then welded and fixed to the barrel portions 10a, 20a. Of course, they can also be screwed together for fixation. This provides the pair of hook portions with strong traction strength for the cylindrical structure A, and allows the cylindrical structure A to rotate around the intersection of the traction line P and the axis L as a fulcrum, adding a lever effect. The internal thread portion 12 can also be welded and fixed to the bottom of the inner cylindrical body 10. When assembled, this results in the structure shown in Figure 13.

[0028] In the present invention, the electric slide buckle can be easily operated by rotating the screw-threading mechanism with an electric drill ED1, as shown in Figure 10. However, if an electric drill mechanism ED2 consisting of a capacitor Ba, an electric motor M, and an antenna An is attached to the end of the electric slide buckle, as shown in Figure 14, the operator can operate a wireless switch S to send an operation signal and remotely drive and operate the electric slide buckle. When electric slide buckles are attached to high places or multiple locations and towed, tightening work can be performed safely and easily compared to manually operating the electric drill ED1. In this case, if multiple electric slide buckles are operated with a single wireless switch, it is preferable to change the frequency of the operation signal so that specific slide buckles can be operated.

[0029] 1 to 6 show the basic configuration of the present invention, while specific structures are shown in the first to third embodiments in Figures 7 to 13, each of which comprises a pair of extendable cylindrical structures A and a mechanism B for threading the pair of cylindrical structures together and driving them forward and backward inside. Increasing the intersection angle α between the axis L passing through the body A constituting the inner and outer cylindrical bodies and the traction line P connecting the pair of hook portions 11, 21 is effective in improving the traction force, but the extent to which the intersection angle α should be increased should be determined taking into account the traction force and the strength of the cylindrical structure constituting the body.
