DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a modular pocketknife system.
The conventional pocketknife is a closed problem-solution system. It is not adaptable to a situation of use, and it is not expandible. That means that as the user of a conventional pocketknife, one must either carry around a large number of different tools in the form of a universally usable and correspondingly heavy pocketknife, or that one becomes the owner of a number of different pocket knives for different situations of use. Neither of these solutions can really give satisfaction.
It is a task of the present invention to provide a portable pocket-tool system which the user can put together from modularly combinable elements and take apart again according to his needs of the moment. This problem is solved by means of the characterizing features of the present invention.
The pocketknife according to the invention allows the owner a universal adaptation to the most varied situations without his having to carry an unwieldy object around with him for that reason. A further substantial advantage of the pocketknife system according to the invention as compared with conventional pocketknives consists in the augmentability at will of an already purchased basic system by means of additional expansion modules. For this reason, the pocketknife system can be unproblematically adapted to the technical advance and to the changing needs of the consumer. A further advantage consists in the reduced stockkeeping of the manufacturer and the dealer since with a relatively small number of modules, a large number of different module combinations can be offered. The modules can be ranged side by side in any desired number and sequence and detachably connected to one another by means of their connecting means.
Examples of embodiments of the invention, as well as of their use, are explained in detail below with the aid of the annexed drawing.
FIG. 1 shows a perspective representation of an embodiment of a single intermediate module of the pocketknife, the resilient safety element thereof being best shown in FIGS. 1a, 1b and 1c,
FIG. 2 shows a perspective representation of a pocketknife system assembled from a number of modules according to FIG. 1,
FIG. 3 shows a perspective representation of another embodiment of a single intermediate module as an electronic memory module,
FIG. 4 shows a perspective representation of the back of the intermediate module corresponding to FIG. 3,
FIG. 5 shows a perspective representation of an embodiment of an intermediate module as a support of two tool blades and for depicting a closed locking lever,
FIG. 6 shows a perspective representation of a pocketknife system according to the invention,
FIG. 7 shows a further embodiment of an intermediate module, and
FIG. 8 shows a section perpendicular to the longitudinal axis of the embodiment according to FIG. 7.
First, the basic construction shall be explained with the aid of an embodiment corresponding to FIG. 1. In this representation it is a question of an intermediate module or interchangeable section mounted with two tools 12, 13. The two tools 12, 13 are mounted in conventional manner on the spindles or arbors 7, 1 and, as in the known pocketknife design, are held fast in their positions by a steel spring 9 which is fixed on the spindle 6. The lateral side plates 14, 15 are likewise fixed by the spindles 7, 1, 6. The side plate 15 is provided with a dovetail undercut, groove-like recess 8 into which a connecting element, corresponding to a dovetail shaped connecting element 11, of an adjacent, additional intermediate module or interchangeable section not depicted in the drawing can be slidingly inserted. Such a sliding connection of two intermediate modules or interchangeable sections is secured by a resilient safety element 5, a safety point 4 thereof being disposed in a recess 4a and also fitting into a recess corresponding to the recess 4a, not visible in the drawing, in the connecting element 11 of a nondepicted intermediate module to secure the two intermediate modules together,
