tool for safely handling belts

Abstract

Tool for safely handling belts. The invention relates to a device for safely moving belts during inspection, disassembly, or assembly on pulleys, without risk of hand injury. It consists of a main rod with two fixed holes at one end for screwing in a knurled shaft and an oblong hole for adapting a second knurled shaft, depending on the thickness of the belt being worked. A removable handle is located at the other end. When the user applies pressure and pulls on the handle, once the belt is clamped between the two knurled shafts, the belt will move according to the user's input. In addition to preventing direct hand injuries, the device multiplies the user's force and reduces musculoskeletal disorders.The device according to the invention is intended for the control, maintenance and handling of all types of belts in all fields.

Description

Title of the invention: Tool for safely handling belts

[0001] The present invention relates to a tool intended to facilitate the handling of belts and pulleys during different phases of control or maintenance of mechanical elements.

[0002] Indeed, for the control, verification, assembly and disassembly of belts, some traditionally use their hands with high risks of pinching and injury to the fingers.

[0003] Others use unsuitable tools and divert them from their primary use, such as screwdrivers, in an attempt to protect themselves.

[0004] The device according to the proposed invention makes it possible to remedy this drawback.

[0005] It includes a main rod with, at one end: 2 belt gripping elements and at the other end, a handle to facilitate handling of the tool. Problematic

[0006] On July 18, 2022, an employee of the company was the victim of a work accident with a work stoppage of 167 days.

[0007] During this incident, the employee was required to manually set the belt in motion so that his teammate could inspect the rotor drive. During this operation, the employee, who was wearing protective gloves, caught his left little finger in the belt and severed a finger joint.

[0008] Several other accidents of this type have unfortunately occurred over the past several years, such as injuries to the inside of the hand caused by a screwdriver that slipped off the strap and tore the skin on the palmar surface.

[0009] It is therefore to protect employees that a working group of men in the trade initiated, created and machined this invention because it makes it possible to meet the requirements of the operating method of the task while keeping hands away from the belt and pulleys.

[0010] It is this distancing of the hand from the source that allows the risk to be recharacterized as a simple danger. Technical context

[0011] According to particular embodiments: - The first end consists of a spindle with two knurled shafts of variable length. One spindle is fixed in one of the 2 predefined holes using a nut and washer while the second spindle is removable in an oblong hole to adapt to the width and thickness of the belt to be worked. - A robust main spindle support rod, of a length to be defined according to the size of the workpiece and ease of movement, and with non-cutting edges to avoid any damage to surrounding elements. - A handle at the other end of the shaft facilitates handling and multiplies the user's force. The handle can be protected to prevent sharp and abrasive edges, thus avoiding hand injuries. The handle can be centered on the shaft or offset to one side or the other. The handle will not be fixed but will consist of one or more moving elements in its center, following the hand's movement.

[0012] The working group's expertise thus highlighted the need:

[0013] The oblong hole: to have a single tool for several types of belts.

[0014] Knurling: to have a rough surface and improve grip on the belt.

[0015] The length of the arm: to reduce strain and multiply the employee's force to move the system.

[0016] The length of the axes: to be able to take 2 or 3 belts for systems with several linked belts.

[0017] Nomenclature:

[0018] 1: Main stem

[0019] 2: Fixed holes

[0020] 3: Oblong hole

[0021] 4: Removable handle

[0022] The attached drawings illustrate the invention.

Claims

Demands

1. A belt handling tool, comprising a main rod (1) having at its first end a belt gripping element and at the other end a removable handle (4) to facilitate handling of the tool, the belt handling tool being characterized in that the gripping element consists of a knurled shaft fixed in one of two holes (2) provided in the main rod (1) and a second knurled shaft removable in an oblong hole (3).

2. A belt handling tool according to claim 1, characterized in that it has non-cutting edges to avoid any damage to surrounding elements.

3. A belt handling tool according to any one of the preceding claims, wherein the removable handle (4) is constituted in its center by a movable element.
