Description

Multifunction Tool

The present invention relates to a so-called. Multifunction tool having a tool body on which one or more tool functions are formed and which has a container. Such a multi-function tool can be used in particular for the maintenance of weapons.

Such multifunction tools have long been known. There are e.g. simple tools made of a piece of sheet metal from which various hexagonal openings and mouth openings are punched, which correspond to the key widths of corresponding screw heads or hexagon nuts.

There are also multi-function tools are known in which different tool elements are arranged folding knife similar, which can be swung individually for use. Such tools may also include a receiving space defined within the tool body between side cheeks and the folded tool elements. Such a tool is known, for example, from DE 298 21 725. In such a tool, on the one hand, for removal of tool elements arranged in this space, all swing-out tool elements must be folded down, so that a corresponding tool element can be removed, and, on the other hand, the tool elements located in the receiving space are accommodated relatively unprotected. Finally, there is a risk that the accommodated in the receiving space tool elements fall out during use of the tool, even if these tool elements are fixed in the receiving space by terminal strips.

In a similar multi-function tool according to folding knife design a beak-like, swing-out container is provided. Here, the container must first swung out and then the "beak" are opened to access the container contents. Also this container offers only little protection against environmental influences. After all, such known multifunction tools are relatively voluminous, depending on the equipment.

It is therefore the object to provide a multi-function tool which is able to accommodate additional elements safely and easily lockable even with relatively flat design and make accessible with equally simple handling without the function and handling of the existing tools is impaired , Another object can be seen in the fact that additional elements are arranged as far as possible captive in or on the tool.

This object is achieved by a multi-functional tool according to claim 1. In this multi-function tool, a swing-out container is provided with an opening on the tool body, which is closed in the retracted position of the container from the tool body itself and is accessible in the extended position. In addition, different tool functions are formed on the tool body itself. This particular arrangement makes it possible to functionally separate the tooling and picking functions from each other so that they do not interfere with each other. The tool can be used for example as a wrench or screwdriver without the risk that the container is opened by mistake.

in the development according to claim 2, the container is designed so that it can accommodate in particular other tools, spare parts, fasteners and adjustment accessories for maintenance of weapons. Especially for certain accessories such as closing gauges, a largely closed accommodation is desirable in order to avoid soiling. The arrangement of the container in a corresponding recess of the tool body a particularly space-saving accommodation is ensured. By connecting with the Tool body via a hinge, the container itself is arranged captive.

According to claim 4 it is ensured that the container remains in the folded position, namely by the spring-loaded locking, so that is released from its folded position neither in powerful operation of the tool or other effects during tool use of the container.

The locking means of a notch according to claim 5, which engages the tool body to a corresponding locking element, provides a reliable latching and locking function with a simple structure.

The development according to claim 6 with an elongated, in particular tubular, cavity, in which the hinge and at the other end the opening and the detent notch are arranged, allows a comparatively large usable space in the case of a slim design and additionally enables the use of the container as a handle element (Similar to a handle shell), when it is arranged in a grip region of the tool body.

The claims 7-14 relate to the particularly advantageous interaction of hinge and locking mechanism, in which a secure closure is guaranteed, an involuntary opening of the container is excluded, a simple operation for opening and / or closing the container and a particularly sheltered housing of the container including contents in the tool body is realized.

The claims 7 and 8 relate to the interaction of a hinge pin and an enforced by this long hole in the container, which together form the hinge mechanism for unfolding, the slot design on the one hand, the engagement and disengagement of the container in the tool body and the others a correspondingly secure guidance when unfolding the

Ensure container.

The claims 9 and 10 relate to the arrangement and execution of a spring which supports the hinge mechanism and at the same time ensures a simple disengagement of the container for unfolding (claim 11).

The design of claim 12 facilitates the folding of the container in the closed detent position without the container must be actively moved in the hinge. The claims 13 and 14 relate to embodiments that ensure a particularly simple and effective handling of the tool when unfolding the container. Due to the design of the actuation zone, the container can also be secured with clammy or gloved hands or with dirty or oil-smeared tools.

The development according to claim 15 makes the container largely disappear in the tool profile. In this case, the container with its projecting beyond the tool profile, possibly convex outer surfaces form a grip zone for actuating the tool. The one-piece design of the tool body allows a particularly simple, solid and insensitive tool design. According to claim 16 are on the tool body itself possibly weapons or weapon type specific desired tool functions formed, especially hook wrench, screwdriver, slotted nut rotors, wrench forks with different key widths, faces, eyelets or the like may be formed.

The design according to claim 17 allows a particularly practical use of the container by being in the unfolded state as a kind of handle, which facilitates the operation of the tool, and serves as a lever arm, can be exercised over the higher actuating forces on a corresponding tool element. An embodiment of the present invention will be described below with reference to the drawing, in which

1 shows a perspective view of a closed-container multi-functional tool according to the invention,

Fig. 2 shows the same tool with the container unfolded,

Fig. 3 shows the tool of Fig. 2 with cut-open container, and

Fig. 4 shows a detailed view of the open container end in the folded but notched position.

The multifunction tool 1 shown in FIG. 1 is formed of a tool body 2 and a tubular container 3. The container 3 is arranged foldable in a corresponding recess 4 in the tool body 2. The tool body 2 surrounds the container 3 in a plane like a frame. The container 3 is connected at one end 5 via a hinge mechanism 6 with the tool body 2. At the other, open end 7 engages a notch 8, which is formed as a cutout in the container end, in the retracted position in a corresponding locking element 9, which is formed by the inwardly facing, the notch 8 opposite end face of the recess 4 , The container 3 is held by a spring mechanism described below in this position, while the locking element largely closes the opening 10 at the container end.

On the tool body 2 itself several tool functions are formed: a hook wrench 11, a Schlitzmutternschlüs- sei 12, two open-end wrenches 13, 13 'with different key widths, screwdriver approaches 14, 14' and an eyelet 15. The eyelet 15 is used to hang the multi-function tool 1. Die Tool functions can be varied according to the intended tool insert. When used as a weapon maintenance tool, there are designs that each have the desired tool capabilities for a particular weapon or weapon type.

The tool body can be made metallic and in one piece as a forging or casting. Further designs can be made from semi-finished sheet metal as a stamped product. The finishing can also be done by conventional methods such as milling, grinding, drilling, etc. It is also possible that additional elements are connected to the tool body, e.g. However, the tool body 2 can also be made of a suitable other material (e.g., plastic) to which certain tool functions are molded or in which elements of another material (e.g., metal) are molded. Such composite construction allows a particularly lightweight design, whereby the appropriate strength remains ensured on the claimed functional elements by the use of metallic materials.

2 and 3 show the container 3 in the unfolded or swung-out position, while the container is shown in Fig. 3 cut and the arranged inside the closing jig 16 shown. The structure of the container shown in Fig. 3 shows an elongated tubular cavity 17 for receiving the Verschlusslehren 16, which is separated by a bottom 18 of a spring chamber 19. At a certain distance from the bottom 18 extend two aligned elongated holes 20, whose long sides each extend in the longitudinal direction or in the locking direction of the container. For coupling the container 3 with the tool body 2 passes through a hinge pin 21, the tool body 2 and the container 3 and the slots 20. The pin 21 is in the assembled state in Werkzeugkδrper 2 fixed (for example, pressed, soldered, riveted, screwed or similar). Between the pin 21 and the bottom 18 is in the

Spring chamber 19 a spring 22 is arranged, which is biased so that it pushes the container 3 in the locking direction, i. in the direction of the opening 10, as far as the elongated holes 20 allow. The container 3 can thus be moved in the longitudinal direction in the slots 20 against the spring force. In the transverse direction, the slots 20 are dimensioned according to the diameter of the hinge pin 21, so that the sliding movement is not impaired in the longitudinal direction, but ensures a secure guidance of the container 3 in the transverse direction.

The hinge 6 opposite the container 3 at the end 7 is open and carries the front side a notch 8, whose depth corresponds approximately to the defined by the slots 20 movement path. The width of the notch 8 corresponds approximately to the thickness of the tool body 2, so that the locking element 9, which is bounded by the corresponding inwardly facing end face of the recess 4, fits into the notch 8. The fact that the container diameter is only slightly larger than the thickness of the tool body 2, the opening 10 is almost completely closed in the folded state by the locking element or the end wall 9.

In another (not shown) embodiment, the thickness of the tool body 2 may also be greater than or equal to the container diameter. In this case, then additional locking elements must be arranged in the end wall region 9, which can then engage in the notch 8. With such a configuration, the opening 10 can also be completely closed.

To unfold from the position shown in Fig. 1, the container 3 is moved against the spring force in the direction A in the slots 20, thereby the notch 8 is disengaged from the locking element 9 (this position is shown in Fig. 4) and can now around the hinge mechanism 6 or about the hinge pin 21 are pivoted out of the frame 4, for example in the position shown in FIGS. 2 and 3. In this position, the opening 10 is accessible. The elements 16 can be removed from or inserted into the cavity 17. To close the container 3 is again moved, pivoted into its folded position and takes when released again its locked position (Fig. 1), in which the locking element 9 engages in the notch.

In order to facilitate the operation, 10 grooves 23 are formed in the end region 7 near the opening, which avoid the sliding of the operating fingers when moving the container 3 in the direction A by improving the adhesion in the longitudinal direction. At the same time, they tangibly identify the end 7 provided with the opening 10. In addition to the illustrated grooves, which may be screwed or molded into the container 30, this actuation zone can also be realized in other ways, e.g. Example by knurling, Riffeiung, a corresponding coating or attaching appropriate actuators.

In the illustrated embodiment, both the unfolding and the folding is only possible when the container is moved in the direction A, so that the notch 8 is lifted out of the locking element 9. In another embodiment, the outer side edges of the container 3 are provided in the opening portion 7 with a slope which abut when folding obliquely on the locking element 9 and move the container 3 by its wedge effect in the direction A during pivoting, so that this when pivoting with its notch. 8 in the locking element 9 occurs. A similar design is also possible to unfold. In many cases, however, it is advantageous to allow the unfolding only when deliberately moving in the direction A, so that an accidental unfolding is prevented. With appropriate stability of the container 3 and the hinge mechanism 6, the container can also be used as a lever that allows, for. B. the screwdrivers 14 and 14 'to operate with greater force. The container 3 can be made of metal, but other materials are also possible, for example a transparent plastic which allows the contents of the container 3 to be controlled.

in the folded-in position, the convex, cylindrical outer surfaces of the containers 3 also assume a handle shell function in that they project beyond the tool body 2, thus increasing the wrench functionality.

Other versions and variations will become apparent to those skilled in the scope of the appended claims.
