Abstract

Pipe wrench or socket wrench, comprising a base body, the base body being tubular, in particular completely tubular, and having at least one receptacle which is designed to receive a screw head or a threaded nut, and wherein the receptacle is circumferentially reinforced at least in some areas by a reinforcing element.

Description

The present invention relates to a pipe wrench or socket wrench.

Pipe wrenches or socket wrenches of the type in question are used, for example, as a spark plug wrench or as a tool for assembling the wheels of motor vehicles. The focus is particularly on tools that are tubular or based on hollow profiles. These are usually easy and inexpensive to manufacture, but wear out quickly. In particular, these tools often cannot transmit high torques.

It is therefore an object of the present invention to optimize the known simple tubular pipe and / or socket wrenches without significantly increasing the costs.

This object is achieved by a pipe wrench or socket wrench according to claim 1. Further advantages and features emerge from the subclaims as well as the description and the attached figures.

According to the invention, a pipe wrench or socket wrench comprises a base body, the base body being tubular, in particular completely tubular, and having at least one receptacle which is designed to receive a screw head or a threaded nut, and wherein the receptacle is circumferentially reinforced at least in some areas by a reinforcing element. It is thus advantageously possible to reinforce the base body locally. According to one embodiment, the receptacle is firmly connected to the base body or is formed integrally. Alternatively, the receptacle can also be designed to be exchangeable. According to one embodiment, the base body has at least one opening in order to arrange, in particular to introduce or plug in, an actuating means for applying a torque. According to one embodiment, the base body has a plurality of receptacles.

According to one embodiment, the base body extends along a longitudinal axis, but can also be angled or curved in at least one direction.

According to a preferred embodiment, the base body is formed from drawn tube. Preferred materials are metallic materials such as aluminum or, in particular, steel.

According to one embodiment, the reinforcing element is designed as a sleeve or as a profile sleeve, the sleeve preferably having a uniform wall thickness. Appropriately, a sleeve shaped or configured in this way has a low weight.

According to one embodiment, a cross section of the sleeve corresponds to a cross section of the receptacle. If the receptacle is shaped as a hexagon, for example, the sleeve advantageously also has a congruent hexagonal cross section. Alternative geometries for the receptacle or for the reinforcing element or for the sleeve are also possible, such as, for example, generally a polygonal or multi-tooth geometry, a triangular configuration, a quadrangular configuration, or even non-angular configurations, such as oval or the like.

The reinforcing element is expediently arranged and fastened on the base body. In particular, according to one embodiment, the reinforcement element is arranged and fastened on the base body or the receptacle after it has been formed or shaped. The reinforcing element and the receptacle preferably form an interference fit. According to one embodiment, the receptacle is designed accordingly, for example locally bulged, arched or the like, in order to enable a secure fit of the reinforcement element. The reinforcing element, in particular the sleeve, preferably closes flush with the receptacle or the base body.

According to one embodiment, the reinforcement element is materially and / or non-positively attached to the base body. According to one embodiment, for example, the reinforcing element is materially connected via an adhesive. As a further alternative, the reinforcing element and the receptacle can also be pressed together by introducing radial force. According to one embodiment, the receptacle is produced by reshaping the base body. In particular, according to one embodiment, the receptacle is produced by expanding a basic shape of the base body.

According to one embodiment, the reinforcing element is reshaped together with the base body and is attached to the base body in the process. This enables both the rapid establishment of a stable and permanent connection and, overall, a rapid manufacturing process.

According to one embodiment, the base body has a round, in particular circular, cross section along its length. Alternatively, the cross section is also angular, in particular polygonal, such as square or hexagonal. According to one embodiment, the receptacle has the same cross section as the base body.

According to one embodiment, the reinforcement element is formed from the same material as the base body. In particular, according to one embodiment, the reinforcement element is shaped and formed from a metallic material, in particular from aluminum or steel. At least the reinforcing element is preferably tempered. An attachment to the receptacle is accordingly advantageously carried out without any significant temperature effect, so as not to weaken the materials.

According to a preferred embodiment, a material of the base body is a metallic material suitable for cold forming, a material of the reinforcing element preferably being a high-strength metallic, in particular tempered, material. The design enables easy deformability of the base body, which means that angled and / or curved geometries can also be represented inexpensively and reliably. The reinforcing element, in particular the sleeve, is expediently made from a high-strength, preferably tempered, metal. Formability is not necessary here. Instead, the tubular wrench or socket wrench can be optimally reinforced locally.

Alternatively, the reinforcement element is formed or manufactured from a non-metallic material, in particular from a composite material, for example. According to one embodiment, the reinforcement element is made from a composite material such as a fiber-reinforced material, in particular a carbon fiber-reinforced material. According to one embodiment, a sleeve for arrangement on the receptacle is molded or manufactured from the composite material and then arranged and fastened on the receptacle. Alternatively, the reinforcement element can be formed from the composite material directly on or at the receptacle, for example by wrapping the receptacle with a suitable semi-finished product and more suitable further processing.

Further advantages and features emerge from the following description of an embodiment of a socket wrench or pipe wrench according to the invention with reference to the accompanying figures.

It can be seen that the base body has a receptacle at the end 12th has, which is designed for the arrangement, for example, a screw nut or the like. A reinforcing element surrounds the receptacle 20th , for example in the form of a (profile) sleeve, reinforced.

2 shows a section as in the 1 outlined. The hexagonal receptacle can be seen 12th , which circumferentially through the reinforcing element or the sleeve 20th is reinforced. In this way, a specific reinforcement of such a pipe wrench or socket wrench can be achieved locally, with the base body 10 as such can be manufactured easily and inexpensively.
