Description

Multifunction Tool

The invention relates to a multifunction tool with two handle parts pivotably facing one another from a parallel position, and with a tool arranged in the region of the pivot point, with at least one additional tool pivotable about an axis which is assigned to the end of the handle part opposite the pivot point, which can be swung out against a stop from a swiveled-in ner position into a use position swiveled out about 180 °.

A multi-function tool of this type is known from US Pat. No. 6,014,787. The tool is a pair of pliers, the ends of which, facing away from the mouth and beyond the articulation, have the pivot point for the handle parts. The additional tools are e.g. a pair of scissors, a screwdriver, a capsule opener, etc. In the safekeeping position, the correspondingly folded-in additional tools are placed in a side cavity in the handle parts, as is the head of the pliers, which has the largest mass. The length of the cavity is partly taken up by the utensils mentioned.

Based on the prior art mentioned, the object of the invention is to improve the generic multifunctional tool in terms of handling.

This object is initially and essentially achieved in a multi-function tool with the features of claim 1, with the aim being that the tool is a corkscrew and the two handle parts can only be pivoted from the parallel position to a stretched position, with limited stops. This leads to a cross grip that is perfectly in the gripping hand. The tool can be used to selectively and the typical corkscrew

BESTÄTIGUΝGSKOPIE Carry out turning operations powerfully. Nevertheless, the parallel position in the sense of the protective or protected frame of the tool can also be taken into account here.

The subject matter of the further claims are explained below in relation to the subject matter of claim 1, but may also be of importance in their independent formulation. It is further proposed that the corkscrew be permanently controlled in an angle bisecting position when the handle parts are pivoted. This creates an increasingly larger, equally large rear grip area and prevents injuries to the corkscrew's spiral body, which is usually somewhat cut-shaped on the periphery. The structural means for this are simple and stable in use. In this way, control is achieved by a tooth engagement of two tooth segments each assigned to one of the two handle parts. The toothed parts lift the handle parts synchronously from the tool or vice versa. In addition, the invention proposes that the corkscrew is an extension of a connecting web which supports the two handle parts in a connecting manner. Such a practically shield-like connecting web fulfills a double function in that it is already a stable base part of the corkscrew. The toothed segment is advantageously formed on a grip shell. A further significance of the connecting web results from spring tongues acting on the connecting web for locking the handle parts in the parallel and extended position. Such precision switching elements are well guided on the connecting web. There is also a structurally advantageous feature due to the axis sections assigned to the connecting web, which connect at least two pockets arranged parallel to one another for the alder forming pivotable additional tools. The lever parts of the transverse handle described above are advantageously extended in a lever manner by means of these swing-out additional tools. A structurally advantageous embodiment also results from fastening screws screwed into the axle sections for fixing the two handle scales. The cohesion is optimized in that the handle shells are connected to one of the alder trees at their free end under a hook insertion latch. Such a hook insertion latch is also hidden from view, so that the exterior of the multi-function tool turns out to be appealing. In addition, it is provided that each of the two handle shells forms a half-pocket, which in the parallel position of the handle parts complement one another to accommodate a pocket that holds a corkscrew. Finally, it is suggested that the bag be offset. This leaves an approximately pocket-long storage space for the additional tools. These can be of greater length than the predecessor described. The additional tools are scissors, a file and / or a knife blade.

The subject matter of the invention is explained in more detail below on the basis of an illustrative embodiment. It shows:

Fig. 17 the multifunction tool partially exposed to visualize the spring tongues for locking the handle parts, in the closed position and

Fig. 18 is the same in the open position. In addition to the actual tool I, the multifunction tool shown includes on-board additional tool II. Tool I is a corkscrew 1.

The free end of the corkscrew 1 ends in a sharpened penetration tip 2. Its helical shaft merges in the opposite direction into a plate-shaped connecting web 3. The corkscrew 1 is thus the protruding extension of the connecting web 3.

The lateral wing 3 'having connecting web 3 placed in the area of this the bearing eye 4 of two handle parts 5 of the multi-function tool. The handle parts 5 take an elongated, book-shaped course and are rounded at both ends.

The mounting of the handle parts 5 on the connecting web 3 is such that they can only be pivoted from a parallel position, as can be seen, for example, from FIG. 1, to an extended position, as can be seen, for example, from FIG. 3. The stretched position is limited, as is the parallel position.

Moved into said stretched position, the multi-function tool takes on a T-shaped profile. The transverse handle G of the tool which is brought into the use position and which has the same protruding leg extends essentially perpendicular to the longitudinal center plane x-x of the multi-function tool, in which the shaft of the corkscrew 1 runs. The corkscrew 1 lies well in the hand in terms of operation.

If, in addition, as can be seen from FIG. 3, the additional tools II are also folded out of their pivoted-in storage position into a position of use pivoted out about 180 °, the lever arms of the transverse handle G are around the Length of additional tools increased. Since parts 5 exerted forces come into effect flat against the handle, the additional tools II correspondingly assigned in a flat position are only available for operating their wide surfaces. During the remaining pull on the cork of a bottle, these additional tools also extend with respect to their narrow surfaces in the back of the transverse handle G of the tool, that is to say facing away from the lower grip edge 6 of the handle parts 5.

In the area of a center-like pivot point 7 of the multifunction tool, which is paired with respect to the bearing eyes 4, there is a relatively large-area support between the connecting web 3 and the handle parts 5 articulated there.

The same also applies with regard to the optional additional tools II which are assigned, as it were, like a satellite, and which pivot about an axis 8, which are assigned to the free end of the handle part 5 opposite the pivot point 7.

Such additional tools II are, for example, scissors 9, files 10 and / or a knife blade 11.

In the folded position, the additional tools II are accommodated in at least two pockets 12 arranged parallel to one another. They are located between alder trees 13. The corresponding storage position can be found in detail in the drawing, as does the handle extension explained using the additional tools II.

The defined, spring-loaded parallel position and extended position of the handle parts 5 is based on snap-acting elements of a type of switching device. This can be seen particularly clearly from FIGS. 17 and 18. The heart of this switching device is a spring tongue 14. This is as a package realized. This consists of three spring tongues 14. Their base 14 'is fixed on the handle part 5. The self-resilient head 14 "rests powerfully on a switching contour provided by the connecting web 3, more precisely its two identical wings 3 '. The front end of the head 14" which is butted against a flank a running parallel to the longitudinal center plane xx secures the position of use. The handle parts 5 can not enter a hyperextension position. The head 14 "rests in a spring-loaded manner in an angular recess of the connecting web 3. However, the handle parts 5 can be pivoted in the opposite direction. This is done in a will-oriented manner, the spring tongue 14 or its head 14" moving over a step edge of the connecting web 3 in order to subsequently move with it a resilient head active surface that has also entered the longitudinal center plane xx against the step-like adjoining outer flank b. This is used to lock the handle parts 5 in the parallel position. The whole thing takes place in a swiveling movement around the bearing eyes 4, more precisely an axis section 15.

The axle section 15 is embedded in pairs in the connecting web 3 (cf. FIG. 4). It penetrates the wings 3 '. On the ends of the axle sections 15 projecting freely on both sides, the stack-like elements which form the multi-function tool and which are assigned to one another are attached. They have suitable openings, denoted throughout by 16.

The axle sections 15 have internal threads open on both sides. Fastening screws 17 can be screwed axially into this. When the sandwich-like or lamella-like structure is closed, the fastening screws 17 pass through the grip shells 18 placed on the outside. The fixation thereof can be seen particularly clearly from FIG. The heads of the fastening screws 17 lie in depressions. The hole-forming opening in this regard bears the reference number 19. The openings in the remaining elements that make up the bearing eye 4 are also designated by 19. The growth of the additional tools II, however, is made out of sight. The relevant bearing journal, axis 8, passes through alder 13, spring tongues 14 and, precisely to form a bearing, the articulation points of the additional tools II. It serves as a rivet 20.

To secure the foot 14 'of the spring tongue 14, riveting is also carried out. The corresponding rivet bears the reference number 21 and passes through bores 22 of the alder 13.

In order to get a good anchoring between the outer tang 13 and the handle shell 18, an additional anchoring is practiced in the vicinity of the rivet 20 forming the bearing journal, that is to say in the region of the handle parts 5 remote from the pivot point. This is concretized in that the handle shells 18 are at their free end under a hook insertion latch with the neighboring tang 13. There is a hook 23 on the outlet side. It is cut out of the tang material and folded out at an angle of 45 ° in the direction of the pivot point 7. In return, a counter hook 24, which is formed on the underside of the grip shell 18, engages under the hook 23, using the free cutting space. This form-fitting hook insert latch 23/24, which thus also supports on the transverse side, is secured by retracting the sleeve-like axle sections 15.

The swivel-mounted handle parts 5 are in mutual engagement. The consequence of this is that the corkscrew 1 is permanently controlled in an angle bisecting position when the handle parts 5 are pivoted. The control results from a tooth engagement of the handle parts 5. For this purpose, a pair of identical grip shells 18 of the two grip parts 5 form tooth segments 25 which protrude beyond the rounded contour of the grip shells 18 on the bearing side. The half thickness of the handle plate facing the subsequent tang 13 is interlocked. len. The teeth of the intermeshing tooth segments are essentially trapezoidal in shape. The arch of teeth goes over a quarter of a circle. The radius point is the geometric axis of the parallel axis sections 15.

In parallel position of the handle parts 5, the tool I, the corkscrew 1, is practically embedded in a trough-like manner. The relevant storage position results, for example, from FIG. 1. The penetration tip 2 can also be seen in the edge protection, so that the multifunctional tool in question can be carried safely as a pocket device.

With structurally simple means, this protective measure is achieved in a functionally reliable manner in that each of the two handle parts 5 forms a half-pocket 26 on sides that are folded against one another in terms of folding technology. These complement each other in the parallel position of the handle parts 5 to form a pocket T which tightly encloses the corkscrew 1. The depth of the pocket T, measured in the thickness direction of the multi-function tool, takes good account of the outside diameter of the coiled shaft of the corkscrew 1 Multi-function tool also includes alder 13 and the spring package. The corresponding clearance is clearly shown in Fig. 16. In this way, an overlapping assignment of the functional parts in the custody position is recognizable. On an upper floor, the corkscrew 1 comes under and the spring tongues 14 for locking the handle parts 5; the additional tools are located on a lower floor.

The room layout is also shown in Figures 12 and 13. As can be seen, the inside of the connecting web 3 ends in the cross-sectional center yy of the tool. The coiled shaft of the corkscrew 1 adjoins the much thinner connecting web 3 in a decentralized manner with a recognizable outward offset going to the right. Lying in the longitudinal center plane xx, the connecting web 3 is given an eyelet 27 while continuing the flank a, this for fastening the multifunction tool to a carrying chain or the like.

As far as the stop-limited, spring-loaded fold-out position and the spring-loaded fold-in position of the additional tools II such as scissors 9, file 10 and / or knife blade 11 are concerned, these defined end positions are reached in the same way as the locking of the handle parts 5 on the connecting web 3 the one around the journal, ie Rivet 8 articulated section of the additional tool tail 28 and a spring tongue 29 cooperating therewith which is also anchored on the foot side. Your bondage goes over the rivet 21 and a hook jaw 30, which is supported on the axle section 15.

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