Description

Background of the invention

The The invention relates to a nail iron or a so-called Kuhfuß or Geißfuß with at least a cranked one Active section which is to attack at and taken off nails or the like, and a grip portion attached to the bent working portion followed.

It are various, known as hand tools serving nail iron, which are all made of a long metal rod, the at least one end of a curved or bent portion having. This section serves as the actual functional or Active section of the nail iron that a user of the nail iron to a nail to be removed or the like applies. The user comprises the nail iron thus applied to its rod-shaped handle portion and swing it over the bend away, whereby the nail to be removed is leveraged.

Underlying task

Of the Invention is based on the object, a nail iron of the above To create kind, which are served and used in the usual way can, but at the same time for the user is easier to handle and more pleasing to use.

Inventive solution

These Task is according to the invention with a Nail iron according to claim 1 solved. Advantageous developments of the invention are described in the dependent claims.

According to the invention is a nail iron created with at least one cranked effective section, the nail used to engage and remove nails or the like is used, and a handle portion which is attached to the bent working portion followed. The active portion is made of a metallic material and the handle portion on its outside at least partially designed from a non-metallic material.

at the nail iron according to the invention is, in contrast to previously known, such tools, the Tool not a total of a single metallic material but it is targeted at least partially in the grip area provided non-metallic material. With the non-metallic Material is possible to adapt the grip area to special requirements and beyond on low cost Way a visually appealing and haptic especially favorable To give grip shape.

Advantageous developments the invention

at An advantageous development of the invention is as non-metallic Material a plastic material at least partially on the outside provided the handle portion. With a plastic material can the inventively designed Handle area of a nail iron in many ways, especially with a non-slip surface be designed.

Especially Preferably, the handle portion is designed with a metallic core, which in particular in the main plane of movement of the bent active section considered has a vertical cross-sectional area. With the metallic core can the for the prying of nails or the like required flexural rigidity of Nageleisenens invention to be provided. At the same time, the handle portion, for example by overmolding the core with a plastic material Various handle shapes and handle colors are adjusted. Thereby can with the same basic model of metallic core a variety various models and embodiments be created.

Furthermore the handle portion of the nail iron according to the invention can be advantageous also completely be formed of a non-metallic material. The grip section can be designed for example from a hollow profile, which with appropriate design a particularly valuable impression can convey and at the same time have high bending stiffness. The such designed bar iron can also be particularly easily formed be, especially for professionally with the iron rail workers constitute an important selling point can.

Further is in the nail iron according to the invention prefers the non-metallic material with the metallic material by a non-positive connection, in particular coupled a screw and / or rivet connection. such Connections can economical be prepared and have the appropriate design of the Coupling section for transmission the bending forces except for Screw and / or rivet connection even under extreme load high durability.

Nails according to the invention Especially in professional use extreme stress exposed. These loads can be a nail iron, which according to the invention is formed, in particular withstand, if the non-metallic Material a fiber reinforced Includes plastic material.

The According to the invention, non-metallic material is preferred with the metallic material, in particular the metallic core coupled by an extrusion coating. Spray technology is a tried and tested technique that has been tried and tested for many years, with the workpieces produced in high quantities can be. At the same time a high variance can be delivered. On changed market requirements can respond quickly and it can also multi-colored and consisting of several plastics encapsulations economical getting produced.

Of the Handle portion of the invention Nageleisens points in the main plane of movement of the cranked active section considered and in particular in the middle of its longitudinal extension a total of vertical cross-sectional area on. This shape of the cross-sectional area is particularly in view on the flexural rigidity of the invention Nageleisens advantage. About that In addition, this form is also special for the hands of a user good grip.

Detailed description of the embodiment

In the 1 and 2 is an embodiment of a nail iron 10 or a so-called Kuhfußes or Geißfußes illustrated, which is substantially along an axis 12 extends. The nail iron 10 is at one of its two end portions with a first cranked effective portion 14 made of forged steel, at the end of which a claw 16 located. At the other end of the nail iron 10 is a second cranked effective section 18 made of forged steel with a flat piece 20 at the end.

Between the two effective sections 14 and 18 extends at the nail iron 10 along its axis 12 a rod-shaped handle portion 22 , This handle section 22 is in the embodiment according to 1 and 2 designed as a hollow cylinder or pipe made of a non-metallic material, namely fiber-reinforced plastic. The grip section 22 is at its end regions with the cranked active sections 14 and 18 each by means of a connection 24 coupled, which is designed as a positive interference fit. In addition, the connections 24 by means of one each across the respective active section 14 respectively. 18 as well as the handle section 22 extending rivet 26 secured.

In the 3 and 4 is an embodiment of a nail iron 10 illustrates which regarding the active sections 14 and 18 like that in the 1 and 2 illustrated embodiment is designed. According to the nail iron 3 and 4 but is the handle portion 22 not hollow but with a metallic core 28 designed, which the two effective sections 14 and 18 interconnected and designed together with these in a single forging process. The core 28 is in the grip section 22 at its entire circumference with a sheath 30 made of a first, relatively firm plastic, in the individual shells 32 or recessed grips are incorporated from a relatively soft plastic. The jacket 30 and the bowls 32 are doing in a single plastic injection process to the core 28 been sprayed.

In the 5 and 6 Finally, an embodiment of a nail iron 10 illustrates which regarding the active sections 14 and 18 again like that in the 1 and 2 illustrated embodiment is designed. According to the nail iron 5 and 6 is the handle section 22 further also with a metallic core 28 designed. This core 28 extends to one with respect to the axis 12 and the Abkröpfbögen the effective sections 14 and 18 formed main movement plane 34 the effective sections 14 and 18 to the surface of the handle section 22 (see top and bottom of the core 28 in the 6 illustrated cross-section of the handle portion 22 ). Related to 6 lateral surfaces of the handle portion 22 is this with bowls 32 molded from a plastic material. In this meadow are the handle section 22 in the main movement plane 34 considered overall with a vertical cross-sectional area 36 and also the metallic core 28 within the grip section 22 with a vertical cross-sectional area 38 designed.

In conclusion, be noted that all Characteristics contained in the application documents and in particular in the dependent Called claims are, despite the formal reference made to one or more certain claims, also individually or in any combination independent protection is to arrive.
