Handle arrangement on a pocket knife or similar

The invention relates to a handle shell arrangement on a consumer article, for example a pocket knife, a flashlight or the like, with a hard plastic core as a connecting element to the housing wall of the consumer article, which carries a soft plastic casing which supports a metal shell.

Such a handle shell arrangement is known from the German utility model 296 08 322.4. This document shows a pocket knife with two housing broad sides facing away from each other. Handle shells are clipped onto these housing walls. The clip connection to the clip projections extending from the housing wall is made by means of a hard plastic core. This core is molded with soft material, whereby the soft material underlies a metal handle shell.

The invention is based on the object of developing the known handle shell arrangement further. The object is achieved by the invention specified in the claims. Claim 1 essentially relates to the fact that a substantially cylindrical shell edge lies in a groove in the casing and is inserted into clamping slots in the hard plastic core with edge sections extending between edge recesses.

This design provides a handle shell arrangement that is easy to assemble and that also has a pleasing appearance. In a further development of the invention, the surface of the soft plastic casing section surrounding the shell edge is flush with the shell's visible surface. This is particularly

VGN 265 098 23 522 DE Dr.G./We./so. 02/24/20 00

It is advantageous if the groove is enclosed all around. The visible surface of the shell then lies in the form of an island in the soft material. In a preferred embodiment, the soft plastic casing section surrounding the edge of the shell is connected to the soft plastic casing section lined with the shell using webs extending through the edge recesses. The flank of the annular groove covered by the shell preferably runs diagonally upwards. The clamp seat can also have a diagonal inner flank from which clamping lugs extend which are spaced apart from the opposite flank and are undersized in relation to the edge thickness of the shell. These clamping lugs ensure that the shell is held in a form-fitting manner in the base area of the groove, which base area is formed by the hard plastic core. The body consisting of the two plastic materials is preferably manufactured using an injection molding process. For this purpose, the hard plastic core is first molded. This is placed as an insert in a second mold and then molded with soft plastic. The metal shell is then simply inserted and clamped by pressing the edge sections into the clamping slots. The handle shell arrangement is preferably assigned to a pocket knife. The assignment of the handle shells to the pocket knife and the design of the pocket knife is described in detail in the generic DE 296 08 322.4, which is why reference is made to it here.

An embodiment of the invention is explained with reference to the accompanying drawings. They show:

Fig. 11 is a representation according to Fig. 1 of the second handle shell arrangement of a pocket knife.

The handle shell arrangement shown in the figures is clipped to a base body of a pocket knife in a manner as described in utility model 296 322.4, with clip extensions being provided on the broad side of the pocket knife base body, which can be clipped into corresponding locking openings 14 of the hard plastic core 1.

The outer contour of the handle shell arrangement is determined by the outer contour of the soft plastic casing 2. This soft plastic casing sits on a hard plastic core 1. The hard plastic core 1

forms a free central section which has a T-shaped cross section and is designated by the reference number 13. The hard plastic core is circumferentially surrounded by a projecting strip 15 which forms an undercut.

After it has been manufactured in an injection molding step, the hard plastic core is inserted as an insert into a second injection mold. There it is molded with the soft plastic shell 2. The resulting body has an edge 10 made of a soft material that engages with the strip 15. Immediately adjacent to the edge section 10, the soft material forms a flank of a groove 5 that extends into the hard core 1 and runs essentially perpendicular to the bottom surface of the hard plastic core 1. The groove is closed in a ring shape and is used to insert the essentially cylindrical shell edge 4 of a metal shell 3.

The groove 5 has an inner flank 12 which rises diagonally so that the groove tapers in a V shape towards its bottom. The diagonally rising flank 12 is formed on the mouth side by a soft material which is associated with the soft plastic casing 2. They are formed by hard plastic in the groove base.

The outer areas 10 of the soft plastic casing are connected to the inner section of the soft plastic casing, which is covered by the metal shell 3, by webs 11. In the area of the webs 11, the hard plastic groove is partially filled with soft material. The webs extend through edge recesses 6 with semicircular cross sections, which are assigned to the shell edge 4.

The shell edge 4 is held in the groove 5 by clamping. The shell is slipped over the central soft plastic casing section 2, with the shell edge 4 entering the groove 5. The outer shell edge sections lie flat against the outer flank of the groove 5. When the shell is fully assembled, the soft plastic casing 2 supports the wide surface of the shell 3.

The clamping slots 8, which are located in the area of the bottom of the groove formed by the hard plastic, are formed by clamping lugs 9, which are spaced apart from one another and are spaced smaller than the outer flank section of the groove, so that the associated edge section 7 of the edge 4 must be pressed into it. Due to the elasticity of the clamping lugs 9, the shell is held in the clamped seat. The contour of the shell surface is curved and is flush with the surface 10' of the soft edge 10.

All disclosed features are (in themselves) essential to the invention. The disclosure content of the associated/attached priority documents (copy of the prior application) is hereby fully included in the disclosure of the application, also for the purpose of including features of these documents in the claims of the present application.
