1. A tool packaging, comprising:
a suspension part, via which a tool having a grooved shaft can be hung, wherein an end of the suspension part has a receiving tunnel through which the shaft of the tool is insertable, and wherein a stop for axially supporting the tool is spaced from the receiving tunnel;
a bracket that is adapted to be snapped in between the stop and the tunnel, wherein at least one projection is formed in the region of the stop and tunnel that is adapted to at least one groove of the shaft.
2. A tool packaging according to claim 1, wherein said at least one projection engages in the at least one groove of the shaft.
3. The tool packaging according to claim 1, wherein the bracket has the at least one projection which spaced from the stop and is adapted to a locking groove of an SDS drill.
4. The tool packaging according to claim 1, wherein the bracket has at least one bar, which is adapted to a rotation synchronization groove of an SDS-plus or an SDS-max drill.
5. The tool packing of claim 1, wherein the receiving tunnel has the at least one projection, which faces the bracket and fits in a locking groove of an SDS driller and extends at an angle of 180\xb0 to a further projection with reference to the drill shaft.
6. The tool packaging of claim 1, wherein the bracket completely fills up a space between the stop and the receiving tunnel.
7. The tool packaging of claim 1, wherein the bracket is flush with the receiving tunnel and the stop when in a snapped-in state.
8. The tool packaging according to claim 1, wherein the stop is cup shaped and has an inner diameter that corresponds substantially to an inner diameter of the tunnel.
9. The tool packaging according to claim 1, wherein the receiving tunnel has two snap-in tongues that can be snapped into one or more recesses of the bracket and are not releasable from the bracket.
10. The tool packaging of claim 8, wherein both snap-in tongues extend laterally to the drill shaft and tangentially to the shaft and engage behind a shoulder on at least one recess of the bracket.
11. The tool packaging of claim 1, wherein the bracket comprises a transparent material.
12. The tool packaging of claim 1, wherein the at least one projection is pressed into the groove of the shaft with pre-stressing.
13. The tool packaging of claim 1, wherein at least one non-circular inner surface is formed on the bracket or the suspension part.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A multibeam antenna comprising:
an antenna element array including one or more feed elements and N (N: natural number) parasitic elements,
wherein the electrical length of one or more parasitic elements are made variable, and
wherein the feed element and N parasitic elements are slot antenna elements.
2. A multibeam antenna comprising:
a first antenna elements array including a first feed element and first parasitic elements; and
a first switching element adapted to vary an electrical length for one of said first parasitic elements,
wherein said one of said first parasitic elements is a first parasitic slot within a conductor.
3. The multibeam antenna according to claim 2, wherein said first switching element divides a slot length of said first parasitic slot.
4. The multibeam antenna according to claim 2, wherein said first antenna element array includes another of said first parasitic elements, said another of said first parasitic elements being a second parasitic slot within said conductor,
said first switching element shortening a slot length of said first parasitic slot to a length shorter than said second parasitic slot.
5. The multibeam antenna according to claim 4, wherein said first feed element is a radiation slot within said conductor, said radiation slot being between said first parasitic slot and said second parasitic slot.
6. The multibeam antenna according to claim 5, further comprising:
a second antenna element array including a second feed element and second parasitic elements; and
a second switching element adapted to vary an electrical length for one of said second parasitic elements.
7. The multibeam antenna according to claim 6, wherein said second antenna element is perpendicular to said first antenna element.
8. The multibeam antenna according to claim 6, wherein said second switching element divides a slot length for said one of said second parasitic elements.
9. The multibeam antenna according to claim 6, wherein said second feed element is another radiation slot within said conductor, said first radiation slot crossing said another radiation slot.
