DETAILED DESCRIPTION OF THE DRAWINGS

[0049] FIG. 1 illustrates an arrangement comprising a drill 10 and a package 30 according to at least one example embodiment of the invention.

[0050] The package 30 in FIG. 1 comprises a protecting portion 34, a locking portion 36 and a gripping portion 38, wherein the package 30 has a geometrical longitudinal axis L. In the illustrated example, the drill 10 is secured to the locking portion 36 of the package 30 in such manner that its geometrical longitudinal axis I coincides or is parallel with the longitudinal axis L of the package 30.

[0051] The protecting portion 34 is arranged to house a cutting portion 14 of the drill 10 in a contact free manner. This is illustrated by a gap Ga located along the longitudinal axis L, and a gap Gb located radially of the longitudinal axis L, both gaps Ga, Gb being defined by the protecting portion 34 and the cutting portion 14 of the drill 10. The protecting portion 34 is substantially U-shaped. The U-shape forms part of first and second subportions in the form of an elongated first leg 32a and an elongated second leg 32b of the package 30, which legs 32a, 32b are linked by a relatively short distal package portion 32c. In the illustrated example embodiment, the first subportion or leg 32a is longer than the second subportion or leg 32b and provides a base from which the locking portion 36 projects. Also, the end of the first leg 32a may be provided with a curve 48 to form the gripping portion 38. The first leg 32a, the second leg 32b and the linking distal portion 32c may all be flexible. Alternatively, it would be conceivable to only have one leg flexible (e.g. the first leg 32a) and the other rigid (e.g. the second leg 32b). Although, the illustrated package 30 is open laterally, in other embodiments it would be conceivable to have one or more lateral sidewalls (33a-33c shown in FIG. 3a-3b), which interconnect the first leg 32a with the second leg 32b similarly to the distal package portion 32c, thus further enclosing/concealing the cutting portion 14 of the drill 10. Furthermore, such lateral sidewalls do not necessarily have to interconnect the legs 32a, 32b, but could for instance extend from the second leg 32b downwards towards but not all the way to the first leg 32a.

[0052] The locking portion 36 is arranged to hold the tool engaging portion 16 of the drill 10. In the illustrated example, the locking portion 36 comprises a snap lock 37. Although, the locking portion 36 in FIGS. 1-2 comprises a snap lock 37, locking by other means are possible.

[0053] The gripping portion 38 is located adjacent the locking portion 36 and may be constructed in various manners. The gripping portion 38 facilitates the handling of the package 30, for example when removing the package 30 from an outer package (not shown) and when installing the drill 10 into a tool holding fixture 80 (shown in FIG. 2c). In the illustrated example, the gripping portion 38 is designed as a lip. This is advantageous since the user 90 may perform the gripping (indicated with the arrows in FIG. 2a) by using a thumb and another finger (e.g. the indexing finger). In one example embodiment the gripping portion 38 may adjoin the locking portion 36.

[0054] When inserting the drill 10 into the package 30, the shaft 26 of the drill 10 is secured to the locking portion 36. In the example embodiments in FIG. 1, this is achieved by that the snap lock 37 in the locking portion 36 first deflects and after the shaft 26 has been placed correctly, elastically springs back. Hereby, a stable and secure locking of the drill 10 is achieved. As mentioned before an outer package may cover the drill 10 and its package 30.

[0055] An example of the process for releasing the drill 10 from the package 30 and connecting the drill 10 to a tool holding fixture 80 is illustrated FIGS. 2a-2c. At least the protecting portion 34 is made from a flexible material thus allowing the user 90 to clamp the cutting portion 14 of the drill 10 by pressing (FIG. 2a) the protecting portion 34 and thereby establishing a contact between the protecting portion 34 and the cutting portion 14 of the drill 10.

[0056] As can be seen in FIGS. 2b-2c, the locking portion 36 and the protecting portion 34 are movable relative each other. When the user 90 clamps the flexible protecting portion 34, and thereby establishes a contact between the protecting portion 34 and the cutting portion 14 of the drill 10, a movement (indicated with a curved arrow in FIG. 2b) of the locking portion 36 relative the protecting portion 34 results in the release of the tool engaging portion 16 of the drill 10 as illustrated in FIGS. 2b-2c.

[0057] In the examples illustrated in FIGS. 2a-2c, the movement between the locking portion 36 and the protecting portion 34 is possible by means of a bendable portion 42 located somewhere between the locking portion 36 and the distal end 32c of the protecting portion 34. In FIGS. 2a-2c the user 90 clamps the gripping portion 38 and the movement of the locking portion 36 relative the protecting portion 34 is achieved by a movement of the gripping portion 38 away from the longitudinal axis L. Accordingly, in FIGS. 2a-2c, the movement of the locking portion 36 relative the protecting portion 34 is achieved by bending.

[0058] In FIGS. 2a-2c the force needed to overcome the holding force of the drill 10 is dependent on the distance between the position where the user 90 clamps the drill 10 and the locking portion 36, and the distance between the locking portion 36 and the position where the user 90 clamps the gripping portion 38.

[0059] Although, the movement in FIG. 2b is achievable by means of a bendable portion 42, other alternatives such as a hinge, a mechanical joint or other similar pivoting means are possible.

[0060] As seen in FIG. 2b, the movement is achieved by pivoting the locking portion 36 around an axis that is perpendicular to the longitudinal axis L of the package 30. In the drawing, this is illustrated as a downward movement, i.e. opposite to the opening of the snap lock 37, which is facing upwards.

[0061] The procedure of releasing the drill 10 can in other words be explained with reference to the fixation of the drill 10 by the three following states:

[0062] State 1: The drill 10 is fixed in a first fixing position by the locking portion 36, (the cutting portion 14 of the drill 10 is housed inside the protecting portion 34) as illustrated in FIG. 1.

[0063] State 2: The drill 10 is fixed in a first fixing position by the locking portion 36, (the cutting portion 14 of the drill 10 is housed inside the protecting portion 34), and the drill 10 is fixed in a second fixing position by the protecting portion 34 (the user 90 clamps the protecting portion 34) as illustrated in FIGS. 2a-2b.

[0064] State 3: The drill 10 is released from the first fixing position by a movement of the locking portion 36 relative the protecting portion 34 while the second fixing position remains unchanged, thus the drill 10 is (only) fixed in the second fixing position by the protecting portion 34 (and is ready to be installed into a tool holding fixture 80) as illustrated in FIG. 2c.

[0065] FIG. 3a-3b illustrates a package 30 according to at least one example embodiment of the invention. FIG. 3a shows the package 30 in its unfolded state, i.e. prior to the fixation of the drill to the package 30. FIG. 3b illustrates a state where the package 30 has been folded to enclose the drill (the drill is not shown in FIGS. 3a-3b). Two grooves 31a, 31b are present on both sides of the short distal package portion 32c allowing for the package to be folded.

[0066] The example embodiment shown in FIGS. 3a-3b has many similarities to the example embodiments shown in FIGS. 1-2 but with some additional features such as lateral sidewall 33a-33c present between the first leg 32a and the second leg 32b of the package 30. Furthermore, the gripping portion 39 and the locking portion 36 are designed a bit differently compared to the example embodiments shown in FIGS. 1-2.

[0067] In FIG. 3a the lateral sidewalls 33a, 33b extends from the first leg 32a and are linked to each other by a distal sidewall 33c, also extending from the first leg 32, such that a U-shaped sidewall is formed. The U-shaped sidewall is designed to enclose the drill. Furthermore, in FIGS. 3a-3b a U-shaped connection part 33d extends from the second leg 32b. The connection part 33d is designed to interconnect with the lateral sidewalls, 33a-33c, thus allowing the second leg 32b to be held to the first leg 32a, as shown in FIG. 3a. In the illustrated example, the interconnection between the connection part 33d and the sidewalls 33a-33c is achieved by means of a snapping function. Of course the lateral sidewalls 33a-33c and the connection part 33d may be interconnected by other means than a snapping function. Furthermore, the lateral sidewalls 33a-33c and the connection part 33d may adopt other designs than the U-shape form exemplified here.

[0068] Release of the drill 10 due to a movement of the locking portion 36 relative the protecting portion 34 is in the example embodiment shown in FIGS. 2a-2c possible by that the user 90 fixates the drill 10 by clamping the protecting portion 34. In an alternative embodiment, the release of the drill 10 may be performed prior to clamping the drill 10. This may be achieved by moving the locking portion 36 relative the protecting portion 34, so that the package 30 itself withholds the drill 10 by for example the first 32a or the second leg 32b of the U-shaped protecting portion 34. Preferably, one or more lateral sidewalls (33a-33c shown in FIGS. 3a-3b), which interconnect the first leg 32a with the second leg 32b are provided in the protecting portion 34. Hereby, after the drill 10 is released from the locking portion 36, the drill 10 may be contained inside the package 30 without being fixated. Connection of the drill 10 to a tool holding fixture 80 is then possible by the before mentioned clamping of the drill 10 by pressing a flexible part of the protecting portion 34.

[0069] The person skilled in the art realizes that the present invention by no means is limited to the embodiments described above. For instance, although the drawings have only illustrated packages containing a single drill, according to other example embodiments, a package may contain two or more drills. For instance, the drills may be arranged in parallel with each other, each one having a tool engaging portion held by a respective individual locking portion. For such a multi-drill package, the subportions of the protecting portion may be wider compared to the elongated legs illustrated in the drawings.
