Problems solved by technology

However, such a handle is unsuitable, for example, in a screwdriver for transmitting large torques, because the core, also in a non-circular cross-sectional shape, has too small a diameter or too small a lever arm for torque generation and is too thin The inner layer of the hole itself does not have sufficient torsional rigidity

Embodiment Construction

[0120] I. Universal application

[0121] In the following, for example, an outer layer is referred to as a handle layer, the outer outer surface of which forms the handle outer surface which is acted upon by the user's hand, while an inner layer adjoins the outer layer radially inwards and encloses a handle core. , the handle core is made of hard plastic and encases a handle rod. However, as a departure from this, for example, the outer layer can be located inside the handle and / or at least one inner layer, handle core jacket or the like can be arranged intermediately between the inner layer and the handle core.

[0122] The invention relates to a handle 1 for a tool, in which a shank 2 of a functional part of the tool is accommodated radially inside and a force of the tool user can be exerted on its radially outside outer surface area, wherein the force can be

Abstract

The invention relates to a handle for a tool, for example a hammer, a screwdriver, a ladle, pliers, a knife or similar. According to the invention, said handle (1) is produced according to the interval-sandwich method for encasing, in a simple manner, the handle core (6) with a handle core covering (9), a soft layer (10) and an external layer (11). The handle core covering (9) and the outer layer (11) are made of a first material, whereas the soft layer (10) is made of a softer, second material.

Description

technical field [0001] The invention relates to a method for producing a handle for a tool, by means of which, in particular, torque can be transmitted. For example the invention relates to a method for manufacturing a screwdriver handle. Background technique [0002] Configuration and criteria for tool handles especially [0003] The manufacturing cost of the handle, [0004] handle weight, [0005] Adaptability of the handle to the hand and mainly to different hand sizes and forces of different users of the handle and / or, [0006] The torque-transmitting capability of forces and moments, especially of tools used to transmit torque such as screwdrivers. [0007] Numerous configurations for tool handles and methods for their production are known from the prior art. [0008] especially for screwdriver handles [0009] US-PS 2,871,899 relates to a first development of handles made of hard plastic for tools such as screwdrivers, in order to improve the tactile feel of the...
