Abstract

Scissors (1) has plastic handles (10, 11) and two metal bodies (2, 3) with cutting edges (29). The metal bodies are connected via a connecting part (4). The eyes (12, 13) of the handles are covered with a soft-touch element (21-24). Preferred Features: The soft-touch elements are connected via connecting elements to each other and/or with the plastic handles.

Description

The invention relates to scissors with plastic handles according to the preamble of independent claim 1.

Such scissors with plastic handles are already numerous from a standing start known in the art, with the free end of the metallic scissor grip stub the plastic handles are attached by means of a receiving opening or are sprayed on. The plastic handles have one, the Scissor grip stub-receiving first part and a second part Grip eyes for holding a user's fingers. Such scissors with Plastic handles are cheaper than scissors made of metal only used especially for simple household scissors.

Such a pair of scissors with plastic handles is known from EP 0 607 223 B1 become, while improving usability in the area of Handle eyes of the plastic handle provided additional covering elements are, which consist of a softer plastic and the area of Cover grip eyes which are in contact with the user's fingers come. This is intended for the user when grasping and using the Scissors create a sympathetic grip feeling, which compared to the Contact with a pure metal scissors a lower feeling of cold and hardness and compared to contact with conventional scissors Plastic handles convey a lower feeling of hardness. One then speaks of Scissors with a "soft touch", ie a relatively soft handle, which however, the scissors should not make them unstable. So in the following it becomes a such covering element made of a relatively soft plastic as a "soft-touch element" designated.

Around the handle eyes of the plastic handle of the scissors with the soft-touch element to cover, it is provided in this embodiment that the soft touch element annular and approximately semicircular in cross section is and with its circumferential surface in the associated grip eye is inserted. The curved surface of the soft-touch element lies here towards the center of the grip eye and the approximately flat part the jacket surface in the direction of the plastic handle.

For improved fastening of the soft-touch element in the grip eye is on the inner surface of the handle eye a circumferential T-shaped rib provided which in a corresponding T-shaped groove in the soft-touch element engages which in the area of the flat part of the surface of the jacket Soft touch element is installed.

Another embodiment of EP 0 607 223 B1 provides the spraying of the Soft-touch element in the grip eye of the plastic handle of the scissors, instead of the connection via the T-shaped tongue and groove connection of the previous one mentioned embodiment.

The disadvantage here is that these types of attachment between the soft-touch element and the handle eye of the plastic handle of the scissors relative are costly because either the all-round T-shaped tongue and groove connection or an additional injection process must be provided.

This means an additional effort in the injection molds, in which the complicated T-rib with regard to the production of the injection molds or T-channel must be introduced. There is also a deployment in this Injection molded plastic handles are not easy to handle accomplish, because the T-shaped ribs / gutters strong undercuts have and therefore the committee in the manufacture of plastic handles or the scissors are not to be neglected.

In addition, the provision of the all-round T-shaped channels in the Soft-touch element whose cross-section is reduced so that it is easy to Damage can occur during use. If one is provided thick-walled soft touch elements, while avoiding the weakening of the Cross section through the T-shaped groove, the soft touch element is then too unstable and the user can then no longer make precise cuts and there is also the risk of loosening the tongue and groove connection.

As an additional disadvantage of this embodiment of the prior art be mentioned that the assembly of the soft-touch element in the Handle eye of the plastic handle of the scissors is not entirely unproblematic, which increases the assembly time, the rejection of defective soft-touch elements or plastic handles or whole scissors is increased and practically no or only a very expensive automatic assembly is possible.

Also through the elaborate assembly of the soft-touch element in the Grip eye makes it difficult for the user himself to use the soft-touch element changes, for example in the case of defects, different users and Adjustment to different sizes and hardness would be necessary.

The object of the present invention is to use scissors of the generic type To provide plastic handle and soft-touch element, which at at least constant stability and user friendliness of the scissors the manufacture and assembly is cheaper.

The technical teaching of the independent claim, with further advantageous embodiments in the dependent subclaims are executed.

An essential feature of the invention is that the soft touch element in the Area of the handle eye of the plastic handle, but outside the inner Circumferential surface of the handle eye, with the plastic handle force and / or is positively connected.

The advantage here is that complicated tongue and groove connections according to the state the technology can be eliminated, which is due to the inaccessible, inner Surface of the handle eye are provided and still a sufficient Stability and ergonomics of the scissors is guaranteed.

By providing the fasteners on the outer surface of the Grip eyes is an inexpensive manufacture of soft-touch elements Plastic handle and thus the entire scissors, possible, including one Automation of assembly is possible.

It is also simple and at the manufacturer and by the user Inexpensive assembly of the soft-touch elements on the plastic handles given by the accessibility of the connection points.

The user can also easily change soft-touch elements. B. in the event of a defect in the soft-touch elements or in the case of different ones Scissors users, for hygienic or ergonomic reasons (Right-handed, left-handed, different sizes, hardness, colors and shapes) is useful.

It is preferably provided here if the soft-touch elements are over Fasteners are interconnected so that they are between them Pinch the plastic handle and thus rest on it. These too can Connection elements between the soft touch elements and the respective one Plastic handle can be provided or a combination of both Connection types.

This attachment of the soft touch elements to the Plastic handles through protuberances and with these protuberances interacting indentations achieved, both the protuberances as well as the indentations in the soft touch elements and also in the Plastic handles can be provided. It is only important that the Protrusions and indentations each with each other in this way interact that the soft-touch elements are suitable for the Plastic handles are held.

The detachable attachment of the soft-touch elements to the Plastic handles, where then latching connections or but clamp connections are provided.

The connecting elements can be made in one piece, for example in shape of cylindrical pins and matching tubular sleeves with which Soft-touch element or the plastic handles can be connected, the pins are inserted into the sleeves and clamped and / or axially locked therein be determined. In another embodiment of the invention, the Pins formed as separate steel inserts to provide a higher To ensure strength against shearing off of the soft-touch elements.

The present invention is also intended to provide that the pins are not in corresponding tubular sleeves, but only in bores clamped and / or latched to the soft-touch elements to fix on the plastic handles.

Of course, any shapes of pin sleeves or pin holes are through covered the invention, so that also conical, spherical, trapezoidal cuboid or other types of connection should be possible.

With all types of connection, it is advantageous if the protuberances and indentations or the pins, sleeves, bores the surfaces of the Soft touch elements do not break through, so that a smooth, even and at the same time elastic, ergonomic and pleasant contact surface with the Fingers of the user of the scissors with anti-slip properties. In addition, this very advantageous attachment is only outside the inner Surface of the grip eyes of the plastic handle due to the better Accessibility easier and cheaper to manufacture and assemble also has a longer shelf life.

Per grip eye of the plastic handle are preferably two to the longitudinal axis of the Plastic handle provided symmetrical soft-touch elements, which then as half-shells the plastic handle on the two large, in cover essential plan scissor pages, so only in Contact area of the user's fingers.

The soft touch element can already have a pre-shaped, ergonomic shape for left-handed and right-handed people or so flexible and elastic be resilient that it is with each use or essentially only when used for the first time to the anatomy of the Adjusts the user's fingers. This allows the scissor handle to open different users, who are also left-handed or right-handed can customize. Due to the possibility of exchanging the soft touch elements can also be customized to the user, depending according to personal needs, cutting tasks and hygiene conditions, respectively.

In the case of two-part corresponding soft touch elements, these can be designed such that the corresponding soft-touch elements can be mounted interchanged. This simplifies it additionally both the manufacturing and assembly costs at the manufacturer as also the installation effort by the user considerably and This reduces inventory costs.

For cost reasons, the soft touch elements can only be used in the area of Grip eyes can be provided or in another embodiment, e.g. B. for aesthetic reasons, additional parts of the plastic handle or the cover the entire plastic handle. However, the stability of the scissors is said to be not be affected and so the relationship of conventional Plastic of the handle to elastic soft plastic of the soft touch elements according to the respective requirements and tasks of the scissors.

The subject matter of the present invention does not only result from the subject of the individual claims, but also from the Combination of the individual claims.

In the following, the invention will be explained using only one embodiment illustrative drawings explained in more detail. Here go from the Drawings and their description further features and advantages of Invention.

Figures 1 and 2 show the scissors according to the invention in one Side view and full size top view of others.

The scissors 1 consists of a first metal body 2 and a second Metal body 3, each with a cutting edge 29, which over each other a connecting part 4 within the bores 9 of the respective metal body 2, 3 are interconnected so that these two metal bodies 2, 3 are designed to be pivotable relative to one another in a scissor-like manner.

These metal bodies 2 and 3 of the scissors 1 are, according to FIGS. 1 and 2, formed on the left of the connecting part 4 as blade parts 5 and 6, which have the cutting edges 29 described above, the cutting edge 29 of the first blade part 5 in FIG. 1 is directed downward towards the leaf edge and the cutting edge 29 of the second blade part 6 up to the edge of the sheet is directed.

To the right of the connecting part 4 are the first handle part 7 and second handle part 8 of the metal body 2 and 3 of the scissors 1. These are only stub-like design, with corresponding stubs on these stubs Plastic handles 10 and 11 are applied, which are glued on, for example or be sprayed on using an appropriate injection molding process can.

These two plastic handles 10 and 11 are now on one side with the Handle parts 7 and 8 of the metal body 2 and 3 connected and have on the opposite free ends each have a grip eye 12 and 13, in which then the user's fingers can be picked up.

According to FIGS. 1 and 2, there is virtually a conventional pair of scissors 1, however, this is compared to the prior art with special Covers on the handle eyes 12 and 13 provided the invention make up yourself.

The respective soft-touch elements are now around the grip eyes 12 and 13 21 to 24 attached, which can be seen according to Figure 2 that this Soft-touch elements are applied in such a way that they blend harmoniously into the Insert plastic handles 10, 11 and are embedded there, what by a Reduction in the thickness of the plastic handles 10, 11 is only made possible.

It is now a first and a second soft-touch element 21 and 22 for Left and right of the first plastic handle 10 via a connection applied between a pin 25 and a sleeve 26 and a second pair of soft-touch elements 23 and 24 to the left and to the right of the second Plastic handle 11 on said connecting elements, pin 27 and Sleeve 28.

These soft-touch elements 21 to 24 are in this way on the plastic handles 10 and 11 attached that the plastic handles 10 and 11 in the area of Grip eyes 12 and 13 on the approximately flat, outer surfaces 18 and 19 cover, as well as the inner peripheral surfaces 16, 17 of the Plastic handles 10 and 11, but the outer peripheral surfaces 14 and Leave 15 of the plastic handles 10, 11 free and finish flush with them.

The connecting elements 25 to 28 are in the form of the pins and sleeves likewise only for the essentially outer, flat surfaces 18 and 19 are provided, but in any case, the inner peripheral surfaces 16 and 17 completely free of these connecting elements 25 to 28.

FIG. 4 shows an enlarged section of the invention Scissors 1 according to Figure 1 in the region of the grip eyes 12 and 13 of the Plastic handle 10 and 11 can be seen, with one removed or still unassembled soft touch element 21. So the lower plastic handle 11 through the soft-touch elements 23 and 24 in the area of the handle eye 13 covered, whereas the first plastic handle 10 located above it only on the back, that is, in the drawing level behind it, the soft touch element 22, is covered and the corresponding first soft touch element 21 drawn away from this is drawn. The first soft touch element 21 has six pins 25 distributed over the surface, which then during assembly through corresponding holes in the plastic handle 10 be passed through this, for inclusion in the corresponding corresponding six sleeves 26 of the second soft-touch element 22.

In Figure 1 as well as in Figure 3 it can be seen that between the two handle parts 7 and 8, a corresponding, spacing web 20 is formed, which forms the stop for the two cutting edges 29 of the metal body 2 and 3.

FIG. 4 shows a section along the section line IV-IV according to FIG. 1, only looking at the scissors from below, i.e. only the upper one Handle eye 12 of the plastic handle 10 can be seen.

It can be seen in particular in FIG. 4 that the connecting elements 25 to 28 between the two soft touch elements 21 and 22 in the area of first, inner peripheral surface 16 of the plastic handle 10 in the area of Handle eyes 12 remain untouched, so that there is no fixed connection of the soft-touch elements 21 and 22 to the plastic handle 10, but this just lie there. The separation axis 30 divides the two soft touch elements 21 and 22.

Through appropriate recesses in the plastic handle 10 are now Sleeves 26 of the second soft-touch element 22 passed so that this second soft-touch element 22 essentially on the first plastic handle 10 abuts on one side and in these sleeves 26 then the pins 25 of the first Soft-touch element 21 are inserted clamping, so that this first Soft-touch element 21 essentially on the other, opposite Side of the plastic handle 10 comes to rest. So now the Plastic handle 10 from both sides through the soft-touch elements 21 and 22, and at the same time these two soft-touch elements 21 and 22 within the corresponding bore of the plastic handles 10 jammed together.
