Definitions
- the invention relates to a multipurpose device with interchangeable tool, especially for mountain and / or ice sports with the characteristics of Preamble of claim 1.
- Such multi-purpose devices are known (AT 377 917, EU-PS 77 769, AT 460 U1; DE 295 00 975 U1).
- FR 2 351 761 A shows and describes a multipurpose device of comparable design.
- the Tool head is designed as a standing U-profile, and in the web of this U-profile two holes are provided, of which the one hole as a threaded hole and the other bore is provided as a through hole.
- the Strength of the part of the replaceable tool used by this tool head is smaller than the inner height of the U-profile.
- This one existing height difference is compensated by an insert plate with two Holes, one of which as a threaded hole and the other hole as Through hole for receiving a screw head is formed.
- Fixing the tool are two parallel to each other in the tool head Screw provided, which screwed into said threaded holes are.
- the interchangeable tool is through the U-profile positioned. Hex wrenches are required to tighten the screw.
- the mentioned insert plate which is received by the U-profile, serves as a mother for the one screw.
- US 4,476,597 A shows and describes a multifunction device.
- the Tool head formed by a bent sheet metal U-part, wherein the stem of the device lies between the two cheeks of this U-part.
- the interchangeable ones Tools are inserted into the two open sides of the U-part and fixed here by means of screws and nuts. The elasticity of this screw ben presses the cheeks of the U-part, between which the tools ge lie.
- the object of the invention is a device of the type mentioned so constructive to make that on the one hand simplifies its manufacture and thus cheaper without affecting its handling.
- the invention is characterized through those measures, the content and subject matter of the characteristic Part of claim 1 are.
- the multipurpose device has a handle 1, which is not shown here and further at the upper end of a tool head 2 is fixed.
- This stalk is conventional designed. It can have a round cross section or a polygonal one or a cross section that lies between these two forms.
- the tool head 2 is plate-like or disk-like and has two plane, mutually parallel contact surfaces 3, 4.
- In this tool head 2 are two adjacent through-holes 5 and two superimposed, slit-shaped openings 6, the latter for receiving a wrist strap, intended. On these loop-shaped openings 6 is not in the following be further discussed, since they do not touch the invention directly.
- Figs. 7 to 10 Two tools, namely a haul 8 and a blade 9, as for example are used together with the tool head 2 are shown in Figs. 7 to 10 shown. Regardless of the type of tool itself is for this essential that it has a tab-like system part 7 with a keyhole-like Recess 10. This has an elongated portion, the end in the present case merges into a hexagonal extension.
- head screws 11 inserted, and expediently such commercial Size and shape and in such a way that the heads 12 of the two capscrews 11 lie on different sides of the tool head 2.
- These capscrews 11 are expediently on the tool head 2, for example by welding or gluing.
- This connection (welding or Gluing) between the tool head 2 and cap screws 11 is the manufacturer made so that the tool head 2, threaded bolt and survey a form a single component.
- the heads 12 now form the elevation, of the Extension of the keyhole-like recess 10 is received, if the tool is mounted.
- the width W of the elongated portion of the recess 10 corresponds to the diameter of the threaded bolt of the cap screw 11. It is within the scope of the invention, commercially available instead of capscrews Size and shape Use special screws here.
- FIGS. 11 to 13 show the two tools fixed to the tool head 2 8 and 9 in different views.
- To disassemble the tools are the on the threaded bolts of the cap screws 11 screwed Hutmuttem so turned up far enough that they are from the surface of the head 12 of the adjacent Head screw have a distance A, at least the strength of S. corresponds to the tab-like system part 7.
- the tool of the Contact surface 3 and 4 of the tool head 2 are lifted, and so far, that the extension of the keyhole-like recess 10 out of operative connection with the head 12 of the adjacent head screw 11 passes.
- Now the tool is laterally offset slightly, so that the extension of the recess 10 and the turned-up cap nut 13 are congruent, whereupon the tool can be lifted off.
- the assembly winds in reverse Order from.
- Figs. 14 to 16 are views of differently shaped tool heads, the Essentially differ from each other in that the slot-shaped Openings 6 opposite to the through-holes 5 arranged differently are.
- a particularly advantageous embodiment of the invention is shown and described.
- a simplified embodiment for example in that the tool head 2 has only one contact surface.
- a simple bolt can be arranged and instead of a single one keyhole-like recess are now in the system part 7 two holes arranged, however, the handling over the above-described Embodiment complicates, since in such a case, the tool change the cap nut must always be removed.
- the survey for anti-rotation may have a circumferential contour that depends on the rotational symmetry deviates, and on this survey itself can set a threaded bolt his. Threaded bolt and anti-rotation device or the through-holes 5 can be arranged one above the other.
