Abstract

The handle (10) has at least three hardness regions. The handle comprises a hard plastic region (12), a soft plastic region (16) and a gel region (18) forming a cushion or pad.

Description

Grab grip

The invention relates to a pincer grip according to the preamble of claim 1.

There is a plurality of grips for tools, in which the grip is adapted both in its section  transverse as in its longitudinal section to the size of a hand considered as normal and to the function of the tool. To this respect, in the known grips it was considered important primarily the way to adapt to the ergonomics of the hand. In addition, certain surface properties were optimized to improve the ease of grip to ensure a certain user comfort

This is how two-component grips are known, which They are composed of two zones, specifically an internal zone which is made of a hard material, to achieve grip resistance necessary, and a second zone that is of a softer material, to guarantee a certain comfort for the user.

From EP 0 538 632 A1 constituting the generic concept a tool grip is known, which has a hard wrap and a soft wrap, which together surround a tool shank. In the soft envelope is an insert that is composed of a plastic
soft.

EP 1 419 856 A1 shows a drill with a housing that is composed of different plastics. By gel-filled packages can be placed under a film to ensure the comfort of a user.

From WO 03/015588 A2 a known grip for a pan and from US 6,158,910 a known pencil, being composed the grip of the pan and the pencil by Different plastics

The invention is based on the objective of creating a tool grip that offers greater comfort for the Username.

For this purpose, the invention provides a grip of pliers with the features of claim 1. The zones individual grip thus have deformable areas so different. In this way it is possible that the grip yields when example a user makes a stronger grip on a given point than in another. The layout of the zones is selected at this respect so that even for a hand of the user that differs from normal and normal size, get caught Better grip.

Preferably the first zone is of a hard material and the material of the second zone is soft, presenting the material of the second zone a hardness greater than the Third zone material. The first hard area of the grip guarantees the necessary resistance to the grip and serves to fix the tool shank in the grip. The second and third zones of the grip allow the grip to adapt to the anatomy of the hand. This way you can avoid crush points that normally appear when the grip is made of a hard material, not deformable

The second and third zones are limited preferably at a certain depth of grip. This it allows a necessary resistance in the first hard zone for the union with the tool.

The material of the third zone is preferably a gel and is configured as a pad. The gels are known to configure the grip surface to tools and present properties that are advantageous for this application, specifically a return to the original form not so fast and elasticity that seems especially suitable.

Other features and advantages are obtained at from the dependent claims. The invention is described below by the preferred embodiment which is represented in the drawings. In the drawings they show:

- Figure 1, a perspective view of a grip according to the invention; Y

- Figure 2, a longitudinal section through two grips according to figure 1.

Figure 1 shows a grip 10 for some tongs, using two handles 10 configured identically  as outlined in Figure 2. The grip 10 shown in this Case is used for pincers.

Each grip 10 has three zones, specifically a first zone 12, a second zone 16 and a third zone 18, forming zones 12, 16 and 18 a continuous surface unitary. In this regard, zones 12, 16 and 18 are made of plastic and they have a different hardness in each case.

The three zones 12, 16 and 18 are shown in this case as continuous zones. The zones may present however also several sections, which also do not have to be arranged related to each other.

The first zone 12 is of a hard material, especially hard plastic, and is manufactured by casting injected

The second zone 16 is also plastic, although soft material. This material is specially commissioned of an ease of grip.

The material of the third zone 18 is a gel and It is set as a pad. The material, which is used for the third zone 18 is the same material as the one used in bicycle saddles Gels have properties that are suitable for use as grips, specifically a return to the original form not too fast and a high elasticity.

The third zone 18 joins with the grip 10 by injection or disposed in the grip 10 by insertion. These procedures are known in themselves, so it is not done reference to them in this document.

The material of the third zone 18 has a hardness less than the material of the second zone 16. Thus the third zone 18 is more deformable than the second zone 16.

The first zone 12 has a recess 14 (figure 2) at one end of the grip 10, in which the tool shank (not shown). The recess 14 is created preferably in the injected foundry of the first zone 12. In the recess 14 the tool shank is arranged with adjustment under pressure or fixed by suitable adhesives.

The union of the rod with the respective grip 10 it can also be done by extrusion coating of the stem (not shown).

Since the first zone 12 houses the stem (not shown) of the tool, it is necessary that the second and third zones 16, 18 are limited to a certain depth of the grip 10. To ensure a lasting bond is precisely important that the tool shank (not shown) is embedded in the non-deformable material of the first zone 12.

The shape of the grip 10 for pliers or Similar tools is known. In this regard, the form of grip 10 is adapted to the anatomy of the hand and presents by both a curved top edge according to figure 2.

The grip 10 has an outstanding section 19, which delimits the grip 10 towards the tool. The section protruding 19 is known in the grips 10. The section protruding 19 can prevent the hand from touching the tool and In this way you get injured.

When handling the tool the hand, especially in the area between the thumb and index finger, it is in contact with the protruding section 19 of the grip 10. Since during all the manipulation of the tool the hand is in contact with the projecting section 19 of the grip 10 and also the area in contact of the hand between the thumb and index finger is especially sensitive, the risk of crush points is big. Therefore the protruding section 19 of the grip 10 in the Hand-directed side is composed of deformable material, especially the gel described above of the third zone 18, while the rear side of the protruding section 19, this it is, the opposite side to the hand, of the first zone 12 is of material hard to ensure the necessary resistance to house the tool and serve to support the hand.

Following the third zone 18 is the second zone 16 is arranged. In this respect the second zone 18 may have a non-slip surface, to increase the ease of grip and thus improve the handling of the tool, so that even with wet and dirty hands it is Simple manipulation possible.

Each grip 10 has a section 20 that is of the same material as the first zone 12. Section 20 prevents a part of the hand, especially a finger, can reach between two grabs 10 and in this respect, be imprisoned.

A hole 22 is shown in section 20, the second grip 10 having an identical hole 22. A pier (not shown) is disposed in a known manner between both grips 10 and This can be helpful when opening the tool.

Through the three zones 12, 16, 18 the grip 10 It can adapt to the anatomy of the hand. The manipulation of grip 10 becomes more comfortable and crush points are avoided in hand.
