Description

AREA

[0001] The present disclosure relates to a device for twisting binding wire for reinforcing steel, in particular a manual, easy-grip twisting device for structural reinforcement. GENERAL STATE OF THE ART

[0002] Reinforced concrete structures are frequently used in the construction industry, with steel reinforcing bars and stirrups secured with binding wire to maintain their positional stability during concreting. Traditionally, rebar tying is done manually using simple hand tools or improvised steel rods with hangers, which lack ergonomic design and defined gripping surfaces. Such tools require repetitive twisting, leading to hand fatigue, palm strain, and reduced efficiency over extended use. While electrically powered rebar tying machines are available, they are expensive, require a reliable power supply, are maintenance-intensive, and unsuitable for small or remote construction sites. Consequently, manual rebar tying continues to present ergonomic and operational challenges. SUMMARY

[0003] The subject matter of the present invention is defined in the claims. BRIEF DESCRIPTION OF THE FIGURES

[0004] Fig. Figure 1 illustrates the isometric view of the device for twisting binding wire for reinforcing bars according to the implementation of the present disclosure. DETAILED DESCRIPTION OF THE INVENTION

[0005] Conventional manual rebar tying tools lack ergonomic grips and require repetitive twisting motions, leading to hand fatigue, palm strain, and uneven ties. While electrically powered rebar tying tools are faster, they are expensive, dependent on electricity, require maintenance, and are unsuitable for small or remote construction sites.

[0006] To overcome the aforementioned limitations, the present disclosure provides a purely mechanical, manually operated device for twisting reinforcing wire, enabling controlled twisting with improved ergonomics and reduced physical strain. The device is structurally simple and requires no electrical power, making it suitable for various construction environments, including small sites and remote locations. The device comprises a hanger provided at one end for hooking a reinforcing wire, the hanger having a curved tip section configured to securely hold the wire during twisting. An intermediate rod extends longitudinally from the hanger and forms the main twisting body of the device.At least one finger grip is attached to the intermediate bar to facilitate controlled application of twisting force with the fingers. A flexible end grip is positioned at the opposite end of the device to support and cushion the palm during operation. In use, the binding wire is manually looped around intersecting rebar, after which the hanger engages the wire loop. Coordinated finger and palm movements apply a twisting motion that rotates the device around its longitudinal axis, twisting the binding wire evenly. The flexible end grip reduces localized pressure on the palm, allowing for extended use with minimal discomfort. The device is economical, durable, easy to use, and improves efficiency by maintaining the simplicity of its design. Fig.Figure 1 illustrates the isometric view of the device 100 for twisting reinforcing wire, wherein a reinforcing wire is first manually looped around intersecting reinforcing elements and loosely positioned for tightening. Subsequently, the hanger 102 provided at the first end of the device is inserted into the looped binding wire, so that the bent tip section 110 secures the wire against accidental loosening during operation.After the intervention, the user grasps the intermediate strut 104 and applies a rotational force via the finger grip 106 to turn the device about its longitudinal axis. This rotates the clamped binding wire in a controlled manner around the reinforcing elements, while the flexible handle 108, positioned at the opposite end of the device, provides a stable palm rest during the rotation and enables a continuous turning motion until the binding wire is sufficiently tightened to secure the reinforcing elements. The device is then released from the twisted wire by reversing or lifting the hanger, thus completing the operation with a purely manual rotational movement, as illustrated in the figure.

[0007] Although the implementations of a device for twisting reinforcing wire have been described with respect to certain structural features and operational aspects, it should be noted that the attached claims are not necessarily limited to the specific components or configurations described. Rather, the disclosed structural elements and arrangements are provided as illustrative examples of implementations of the device for manually twisting reinforcing wire.

Claims
