[0063] Figure 6 is a view of the magazine in Figure 5 from a different angle.

[0064] Figure 7 illustrates another fastener magazine, which is shorter than the magazines in Figures 5 and 6; and

[0065] Figure 8 illustrates an alternative latch mechanism to the one in Figure 4, which can be used in a fastening means similar to the one in Figure 3.Detailed description of the invention

[0066] Referring now to Figures 1 to 3, a driving tool 1 can be seen comprising a magazine support arm 2 equipped with a fastening means 3 for fastening a fastener magazine 4 to the arm 2. The fastening means 3 comprises a releasable latch mechanism 5 for selectively fastening the magazine 4 against the arm 2 and three stops 6 for limiting the recoil of the magazine 4 when the driving tool 1 is fired.

[0067] The driving tool 1 comprises a housing 10, a handle 11 , and a drive section 12 which is designed to drive a fastener F from the magazine 4 when the magazine 4 is mounted on the arm 2. The drive section 12 comprises a nose 13, which can be in the form of an opening, a recess, an open barrel, or a similar feature. The nose 13 comprises a pair of pins 14 that depend from it to engage in the magazine 4, as will be explained below.

[0068] In this example, the driving tool 1 comprises a combustion-powered tool equipped with an internal combustion engine (not illustrated) for driving the fasteners F through the nose 13. However, other drive means have also been considered, such as compressed air, electromechanical drive means, or any other suitable arrangement.

[0069] The arm 2 extends along an axis Ai that is substantially perpendicular to an axis A2 of the nose 5. In this example, the axis Ai of arm 2 is inclined in order to correspond to the inclination of the fasteners, for reasons which will be apparent to the person skilled in the art.

[0070] The latch mechanism 5 is mounted on the arm 2 near its distal end relative to the nose 13. The stops 6 protrude from a main side, namely a magazine mounting side 20, of the arm 2 and are spread out along the axis Ai of the arm 2. Each stop 6 comprises a stop surface 60 that is substantially perpendicular to the axis Ai of the arm 2.

[0071] In this example, stops 6 and [missing number] comprise a wall 61 perpendicular to the axis Ai of the arm 2, which provides the stop surface 60. The wall 61 is reinforced by three spaced ridges 62 extending from the wall 61 along the axis Ai of the arm 2 on the side of the wall 61 opposite the stop surface 60.

[0072] The latch mechanism 5, illustrated more clearly in Figure 4, comprises a knob 50 mounted on the arm 2 by a leaf spring 51 . The knob 50 is generally L-shaped, with an actuating part 52 extending along the axis Ai of the arm 2, and a locking part 53substantially perpendicular to the actuating part 52.

[0073] The actuating part 52 comprises a serrated actuating surface 52a that is inclined toward the locking part 53. The locking part 53 comprises a lip 54 for engaging the magazine 4 in order to keep it against the arm 2. The leaf spring 51 comprises a mounting end 55 attached to the arm 2 by a screw V, a curved connecting part 56 captured by the locking part 53, and a curved pivot part 57 connecting the mounting end 55 to the curved connecting part 56.

[0074] As a result, actuating the actuating part 52 rotates the knob 50 relative to the arm 2 by elastically distorting the curved pivot part 57. Releasing the actuating part 52 enables the knob 50 to return to its initial, locked position.

[0075] The magazine 4, illustrated more clearly in Figures 5 and 6, comprises a plurality of fasteners F, a fastener outlet 40 at one end, and eyelets 41 on either side of the outlet 40. The magazine 4 also comprises a coupling element 42 that protrudes from a mounting side 43 of the magazine 4, toward a second end of the magazine 4, and three openings 44 in the mounting side 43 that are spaced along the length of the magazine 4 between the coupling element 42 and the outlet 40.

[0076] The coupling element 42 is substantially box-shaped with an open side forming a lip 45 at its free end and a pair of inclined sides 46 extending from the lip 45 and widening toward the mounting side 43 of the magazine 4. The lip 45 is designed to engage part of the latch mechanism 5, for example its lip 54, with the coupling element 42.

[0077] The magazine 4 is mounted on the driving tool 1 by inserting the pins 14 that depend from the nose 13 into the eyelets 41 of the magazine 4, with the magazine 4 slightly inclined relative to the mounting side 43 of the arm 2. In this position, the openings 44 on the magazine 4 are aligned with the stops 6 on the arm 2, and the knob 50 is aligned with the coupling element 42.

[0078] When the magazine 4 is moved toward the mounting side 43 of the arm 2, the coupling element 42 comes into contact with a ramp 58 on the locking part 53 of the knob 50 and moves the knob 50 away from its locked position, thereby distorting the leaf spring 51. Further pushing the magazine 4 causes the lips 45, 54 to align and the knob 50 to return to its locked position and engage with the coupling element 42.

[0079] In this configuration, the knob 50 presses the magazine 4 against the nose 13 to enable the nose 13 to be fed with fasteners F from the outlet 40 on the magazine 4. Inserting the pins 14 that depend from the nose 13 into the eyelets 41 on the magazine4 slidingly connects the magazine 4 to the nose 13.

[0080] When the driving tool 1 is fired, the magazine 4 recoils and slides along the arm 2, but the knob 50 keeps the magazine 4 against the arm 2 and absorbs part of the recoil force until the stops 6 engage with one of the rims on the openings 44 to limit this sliding movement.

[0081] Figure 7 shows a magazine 104 according to another example similar to the magazine 4 in Figures 5 and 6, where similar references represent similar features, incremented by 100. The magazine 104 in this example differs from the one in Figures 5 and 6 in that it is shorter and contains fewer fasteners F. However, this magazine 104 comprises eyelets 141 , a coupling element 142, and openings 144 similar to the ones in the magazine 4 in Figures 5 and 6. It can therefore be mounted on the same driving tool 1 and works similarly to the one explained above.

[0082] Figure 8 shows a latch mechanism 105 according to another example similar to the latch mechanism 5 in Figure 4, where similar references represent similar features, incremented by 100. The latch mechanism 105 in this example differs from the one in Figure 4 in that the knob 150 can be pivoted around an axis 157 and the latch mechanism 105 comprises a pair of compression springs 151 that can be compressible to enable the knob 150 to pivot out of engagement with the magazine 4.

[0083] More specifically, the latch mechanism 105 comprises a mounting bracket 155 attached to the arm 2 by a screw V, and the knob 150 is pivotally connected to it by the axis 157. The mounting bracket 155 comprises a reinforcement part 159, which is parallel to the actuating part 152, and the compression springs 151 are held between the actuating part 152 and the reinforcement part 159. The axis 157 is located at the junction between the actuating part 152 and the locking part 153, so that actuating the actuating part 152 to compress the compression springs 151 causes the locking part 153 to pivot out of its locked position. Subsequently releasing the actuating part 152 causes the locking part 153 to return to its locked position, similar to the locking mechanism 5 described above.

[0084] The person skilled in the art will understand that the embodiments described above can vary in many ways.List of Reference Numbers1 driving tool10 housing1 1 handle12 drive section13 nose14 pin2 magazine support arms20 magazine mounting side3 fastening means4 fastener magazine40 fastener outlet41 eyelet42 coupling element43 magazine mounting side44 openings in the magazine mounting side45 lip on the coupling element46 sloped sides of the coupling element5 latch mechanism50 knob51 leaf spring52 actuating part52a serrated actuating surface53 locking part54 locking part lip55 leaf spring mounting end56 curved connecting part of the leaf spring57 curved pivot part of the leaf spring58 ramp on the locking part6 stop60 stop surface61 wall62 ridgeF fastenerAi axis of the armA2 axis of the noseV screw104 magazine140 fastener outlet141 eyelets142 coupling element143 magazine mounting side144 openings145 lip on the coupling element146 sloped sides of the coupling element105 latch150 knob151 compression spring152 actuating part153 locking part154 locking part lip155 mounting bracket157 axis158 ramp on the locking part159 reinforcement part
