  • a hand tool in accordance with the present invention suitably comprises a first part 1 and a second part 2 releasably connected to each other using a locking device, arranged to allow the parts 1, 2 to engage with each other so as to form a connected state in which said parts 1, 2 together form said hand tool.
  • the locking device is arranged to provide a rotational engagement between the parts 1, 2, and comprises a bushing 3, arranged on the first part 1 and permanently fastened to the first part 1 with a fastening means 4, and at least one, preferably at least two (see below) non-circular through hole 5, 6, arranged in the second part 2.
  • the bushing 3 and the hole 5 are arranged to engage so as to provide a releasable attachment, wherein the hole 5 features a shape allowing the bushing 3 to be inserted into the hole 5 when the bushing 3 is in a first rotational relationship with the hole 5 and to retain the bushing 3 when the bushing is in a second rotational relationship with the hole 5.
  • the hand tool can be placed in a housing 7 for holding the parts.
  • the housing 7 may also function as a third part of the hand tool.
  • the second part 2 can be attached to a further bushing 8 attached to a pliers part 32 that is mount ⁇ ed on the rear of the housing 7, which bushing 8 is similar to the bushing 3 and also arranged to engage in a correspond ⁇ ing manner with a through hole 6, on the second part 2, similar to through hole 5 (above) .
  • Fig. 1A shows the first part 1, in the shape of one half of a piece of hand-operated scissors.
  • the first part 1 consists of a metal blade 9 comprising a cutting edge 10 and a locking device attached to it, wherein the locking device comprises the above discussed bushing 3 and a fastening means 4, for permanently fasten the bushing 3 to the metal blade 9.
  • the metal blade 9 also comprises a sharpened edge, 31 opposite the cutting edge 10, as shown in Fig. 1A and IB.
  • the sharpened edge 31 can for example be used as a smaller knife, or can be used to make up fire with a fire striker.
  • the fas ⁇ tening means is preferably a rivet or a screw (as shown in Fig. 5B) .
  • the first part 1 further has a handle 11 with a finger hole 12 for handling the tool by hand.
  • the metal blade 9 is partly inserted into the handle 11.
  • the handle 11 is preferably made of plastic material molded to the metal blade 9. Of course also other suitable
  • the metal blade 9 is further provided with a cavity forming a can opener 13 and another cavity forming a bottle opener 14.
  • Fig. IB shows a rear side view of the first part 1, wherein the sharpened edge 31 and the cutting edge 10 is visible.
  • the figure also shows a through hole 25, wherein the bushing 3 is inserted and attached with the fastening device 4.
  • the metal blade 9 of the first part 1 further has a shape which allows the metal blade 9 and the metal blade 15 of the second part 2 to be pressed against each other when engaged with the locking device.
  • This feature can preferably be achieved by a slight concave shape in longitudinal direction of the metal blade 9 of the first part 1, on the side of the metal blade 9 abutting the metal blade 15 of the second part 2, once the first and second parts have been engaged to each other using the locking device. This slight concave shape results in a higher pressure against the metal blade 15 of the second part.
  • the shape is concave in the sense that the face of the blade 9 arranged to face the opposing blade 15 when mounted, is not planar, but rather slightly curved in longitudinal direction of the metal blade 9 in the plane perpendicular to the plane shown in fig. 1A, between the bottle opener 14 and the can opener 13, so that the end portions of that part of the blade 9 are located closer to the opposing blade 15 as seen in the main extension plane of the blade in question.
  • This feature ensures that there is no play or looseness, apart from the rotational engagement provided by the locking part 3, 4, when the first part 1 is attached to the second part 2 using the bushing 3.
  • the concave shape of the metal blade 9 on the first part 1, has preferably a maximum protuberance of about 0,5-1,5 mm from a straight line, along the longitudinal direction of the metal blade 9, between the bottle opener 14 and the can open ⁇ er 13.
  • Fig. 2A shows a side view of the second part 2 of the hand tool, in the shape of a knife.
  • the second part 2 of the hand tool comprises a metal blade 15 and a handle 16 with a finger hole 17.
  • the metal blade 15 is partly inserted into the han ⁇ dle 16.
  • the metal blade 15 of second part 2 comprises at least one through hole 5, 6 each arranged to engage with one or several respective bushings 3, 8.
  • the metal blade 15 pref ⁇ erably comprises two non-circular through holes 5, 6 located at a distance from each other in the longitudinal direction of the metal blade 15.
  • the first non-circular through hole 5 is located near the handle 16 of the metal blade 15 and the second non circular through hole 6 is located closer to the tip of the metal blade 15.
  • the shape of the non-circular through holes 5, 6 is individu- ally adapted to allow one or more protrusions 18 of the bush ⁇ ing 3, 8 to pass through the hole and, after pivotal movement of the handle 16, to lock the first part 1 to the second part 2 using the bushing 3 as shown in Fig. 5A, or to attach the second part 2 to the bushing 8 arranged on a pliers part 32 on the rear of the housing 7 as shown in Fig. 7.
  • the through holes 5, 6 are arranged to allow the protrusions 18 of the bushing 3, 8, as can be seen from the figures 2A and 2B, to pass through the respective through hole.
  • the shape of each through hole 5, 6 essentially corresponds to the shape of the protrusions 18 of the respective bushing 3, 8 in the plane of relative rotation between the parts 1, 2 when engaged forming said connected state.
  • the handle 16 is preferably made of plastic material molded to the metal blade 15. Of course also other suitable materi ⁇ als could be used.
  • Fig. 2B shows a rear side view of the second part 2.
  • the rear of the through holes 5, 6 are visible, showing that each respective through hole comprises a countersunk hole or cavity 21, 22 which is aligned with the through hole 5, 6 and in which where the bushing 3 can be rotated after being inserted through the respective hole.
  • This countersunk hole 21, 22 further ensures the lack of looseness/play after having attached the second part 2 to the first part 1 using the locking device.
  • the metal blade 15 of the second part 2 has a cutting edge 19 on the top of the metal blade.
  • the knife edge 20 of the metal blade 15 has a curved shape to function as a conven ⁇ tional knife.
  • the second part 2, the knife part differs from other prod ⁇ ucts in that the cutting edge 19, to be used as one half of a pair of scissors, is located on the back of the knife and not at the knife edge 20, as in other conventional hand tools. Since, for instance, the scissor function requires a cutting edge with considerably larger edge angle than the knife func ⁇ tion, this allows for better specialization of the scissor function.
  • the second part 2 In order to attach the second part 2 to the first part 1 the second part 2 has to be positioned so that its main direction of elongation of its blade is at a predetermined angle, pref- erably 90 degrees angle, in respect to the main direction of elongation of the blade of the first part 1.
  • the protrusions 18 on the bushing 3 of the first part 1 will then match the shape of the through hole 5 or 6 in the second part 2, so that the parts can be joined together and wherein the first and second parts thereafter are pivoted around the bushings axis into a locked, connected state.
  • the metal blades of the first and second part 9, 15 are hence pivotable about said locking device, so that cutting edges of said first and second part slide against each other when their respective handles 11, 16 opposite to the pivot are closed.
  • the handles 11, 16 When in the connected state, the handles 11, 16 will be held firmly in position against each other, and the parts 1, 2 will together work as a pair of scissors (shown in Fig. 5A and 5B) .
  • the bushing 3 and said slightly curved shape of the metal blade 9 of the first part 1 ensures a tight fit and no play or looseness between the two parts 1, 2.
  • the second part 2 further has a cutting edge 30 constituting one part of a set of pliers when the second part 2 is con ⁇ nected to the housing 7 using a second bushing 8 and the hole 6. It is important that there is no play or looseness between the metal blades of the first and the second parts in the connected state. Such play/looseness is prevented by the locking device in combination with the concave longitudinal shape of the metal blade 9 of the first part 1.
  • the slightly curved shape of the metal blade 9 on the first part 1 forces the metal blades 9 and 15 against each other when engaged with the bushing 3.
  • Fig. 3A shows a side view of another embodiment of the second part 2.
  • the hole 5, 6 has a central circle area (5A, 6A) with projecting protru- sions in the form of half circles (5B, 6B) .
  • edge por ⁇ tions (5C, 6C) are formed on each side of the half circular protrusions (5B, 6B) .
  • This embodiment has shown to be especially advantageous with regard to the lack of play or looseness when the first part 1 or housing 7 is attached to the second part 2 using the bush ⁇ ing 3 , 8.
  • the second part 2 further has a combined abdominal opener and cutting edge 35, constituting one part of a set of pliers when the second part 2 is connected to the housing 7 using a second bushing 8 and the hole 6.
  • the abdominal opener is used for opening up the abdominal of an animal during slaughter.
  • the shape of the abdominal opener has the advantage that it, in contrast to a conventional knife, protects the stomach and other organs in the animal during the slaughter. If a conventional knife is used there is a risk that the stomach of the animal is damaged.
  • the combined abdominal opener and cutting edge 35 can be used with any shape of the through holes 5 and 6 and that it can be used as one part of a set of pliers in the same way as has been described for the cutting edge 30.
  • the cutting edge 30 can be used with any shape of the through holes 5 and 6.
  • Fig. 3B shows a rear side view of the embodiment shown in Fig. 3A.
  • the shape of the through holes 5 and 6 are as have been described above, as well as the combined abdominal open ⁇ er and cutting edge 35. All other parts of the second part 2 are as have been described above for Fig. 2A and 2B.
  • Fig. 4A shows the bushing 3, 8 of a locking device.
  • the bushing 3, 8 comprises at least one protrusion 18, arranged es ⁇ sentially in parallel to a main surface of a part to which the bushing 3, 8 is permanently fastened using a fastening means 4.
  • the bushing is adapted to be permanently mounted on the first part 1 or the pliers part 32 using fastening means 4, such as for example a rivet or a screw, (shown in Fig. 5B) by being inserted through a central through hole 23 in the bottom of the bushing 3, for receiving the head of such a fastening means 4 in a countersunk manner.
  • the at least one protrusion 18 in the upper end of the bushing 3 can for example be a flange, an asymmetrical shaped cam or any other shape giving a clamping connection when inserted through the holes 5 or 6 and rotated.
  • the bushing preferably comprises three flanges as shown in Fig. 4A, but could also comprise 1, 2, 4, 5 or more flanges. As mentioned, the flanges could also have other shapes. It is important that the non-circular holes 5, 6 on the second part 2 are adapted to match both the shape of the flanges and the number of flanges on the bushing 3, 8. This ensures that the bushing 3, 8 is tightly connected to the countersunk hole 21, 22 in the metal blade 15.
  • Fig. 4B shows that the bushing 3, 8 is arranged with a through hole 23, wherein the means of the lower end of the through hole 23 has a non-circular cam shape 24 on a part of the hole 23 to cooperate with a fastening means 4 when at ⁇ tached to said first part 1 of the hand tool.
  • the fastening means 4 is arranged so as to limit movement between the fas- tening means 4 and the bushing 3, 8, when the bushing is permanently fastened with the fastening means 4 on the metal blade 9 or the pliers part 32.
  • the bushing 3 is inserted through a through hole 25 (shown in Fig.
  • the bushing 8 is in a similar way inserted through a through hole 33 (shown in Fig. 8B) in the pliers part 32 and the fastening means 4 is thereafter inserted in the hole 23 and compressed, whereby the non-circular cam shape 24 contributes to a tight and permanent mounting of the fastening means 4 in the bush ⁇ ing 8.
  • the fastening means 4 fits very tightly in the hole 23 of the bushing 3,8, both in a rotational direction and in a direction in which the part is retracted from the metal blade 9 or the pliers part 32. It is hence not possible to remove the bushing from the first part 1 or pliers part 32 once the fastening means 4 has been put into place. This further en- sures the lack of play or looseness in the locking device, since there is no way for the bushing 3, 8 to move, neither in a direction in which the part is retracted from the pliers part 32 or the metal blade 9, nor in a pivotal direction in relation to the other part.
  • the tight fit also reduc ⁇ es/eliminates the risk of water entering the bushing and thereby minimizes the risk of rust.
  • Fig. 5A shows a front view when the first part 1 has been attached to the second part 2, by bringing the bushing 3 through the hole 5, to form said connected state, the handles 11, 16 have been pressed towards each other and the locking device has been engaged.
  • the first and second parts 1,2 are pivoted around the bushing 3 into a closed state of the pair of scissors, the cutting edge 10 of said first part 1 and the cutting edge 19 of said second part 2 slide against each other as the handles are closing.
  • the protrusion 18 of the bushing 3 are rotated out of alignment with the corresponding shape of the non-circular through hole 5, and engage in a pressing fashion with a surface of the countersunk hole 22 on the metal blade 15.
  • the concave shape of the metal blade 9 of the first part 1 gives a further pressing fashion with the surface of the metal blade 15 of the second part 2.
  • the second part 2 To separate the first part 1 from the second part 2, the second part 2 must again be oriented so that the general longitudinal direction of the first part 1 is at a predeter- mined, preferably 90 degree, angle to the general longitudi ⁇ nal direction of the second part 2, whereby the protrusion 18 of the bushing 3 align with the corresponding non-circular through hole 5.
  • the locking device will then be in an open position and the parts can be pulled apart, and subsequently stored in the housing 7.
  • Fig. 5B shows a rear view when the first part 1 has been attached to the second part 2 in said connected state, form ⁇ ing a closed pair of scissors. This view also shows the fas- tening means 4 when attached in the bushing 3 through the through hole 24 in the metal blade 9 on the first part 1.
  • Fig. 6A shows the first 1 and second 2 parts when they are held in the housing 7.
  • the housing 7 does no only function as a holding place, it also forms a multi-purpose hand tool together with the first 1 and the second 2 part.
  • the multi ⁇ purpose hand tool further comprises a fire striker 26, a sharpener 27 for metal blades and one part of a set of pliers 32, all attached to the housing 7.
  • Fig. 6B shows a rear view of the first 1 and second 2 parts when they are held in the housing 7.
  • the housing 7 further comprises a belt hanger 29.
  • the belt hanger 29 can be at- tached and removed from the housing 7 by rotation of the belt hanger.
  • the housing 7 further comprises a pliers part 32 with a bushing 8 to releasably attach the second part 2 to the rear of the housing 7, wherein the cutting edge 30, 35 on the second part 2 and a cutting edge 28 of the plier part 32 on the housing 7 together forms a set of pliers (shown in Fig. 6A, 6B and 7) .
  • the bushing 8 is attached to the plier part 32 on the housing 7 in a similar way as has been described for attaching the bushing 3 to the first part 1. It is noted that the bushing 8 works together with either through hole 5, 6 in the corresponding way as the bushing 3.
  • the second part 2 and the housing 7 can together form a mul ⁇ ti-purpose hand tool, as described above, wherein the housing 7 comprises a bushing 8, allowing the second part 2 to be releasably attached to the housing 7 and thereby forming a set of pliers.
  • Fig. 7 shows a rear view of the housing 7 when the second part 2 and the housing 7 have been put into mutual engagement using the bushing 8, and the through hole 6, so as to together form said set of pliers in a connected state similar to the above described connected state between parts 1, 2.
  • the second part 2 has to be put in a predetermined, preferably 90 de ⁇ grees, angle in respect to the housing 7, in a way that cor ⁇ responds to the above described between parts 1 and 2.
  • the bushing 8 on the housing 7 will then be aligned with the matching shape of the through hole 6 in the second part 2, so that the parts 2, 7 can be joined together and then brought into said connected state by a rotational motion in relation to each other.
  • the housing 7 will function as the second handle of the set of pliers. Hence, when the housing 7 and second part 2 are pivoted in relation to each other and about the engagement means comprising the bushing 8 and the through hole 6, the cutting edges 30, 28 will slide against each other and form the set of pliers as the handles 16, 7 closes. It is to be noted that the combined abdominal opener and cutting edge 35, shown in Fig. 3A and B, can be used instead of the cutting edge 30 and will work in the same way.
