[0063] [Fig.7] [Fig.7] illustrates another magazine for fastening elements, shorter than the store of figures 5 and 6; and

[0064] [Fig. 8] [Fig. 8] illustrates a different latching mechanism than that of [Fig. 4], which can be used in a retaining means similar to that of [Fig. 3]. Detailed description of the invention

[0065] Referring now to figures 1 to 3, we can see a driving tool 1 comprising a magazine support arm 2 having a retaining means 3 for retaining a magazine of fasteners 4 to the arm 2. The retaining means 3 includes a latch mechanism 5 which is releaseable to selectively retain the magazine 4 against the arm 2 and three stops 6 to limit the recoil of the magazine 4 when the driving tool 1 is pulled.

[0066] The plunger 1 comprises a housing 10, a handle 11, and a drive section 12 designed to drive a magazine fastener F when the magazine 4 is mounted on the arm 2. The drive section 12 includes a nose 13, which may be in the form of an opening, a recess, an open barrel, or a similar feature. The nose 13 includes a pair of pins 14 that rely on it to engage with the magazine 4, as will be explained below.

[0067] The driving tool 1 includes a combustion tool in this example, equipped with an internal combustion engine (not shown) for driving the fastening elements F through the nose 13. However, other drive means are also envisaged, such as compressed air, electromechanical drive means or any other suitable arrangement.

[0068] The arm 2 extends along an axis Ai which is substantially perpendicular to an axis A2 of the nose 5. In this example, the axis Ai of the arm 2 is inclined to correspond to the inclination of the fixing elements, for reasons which will be appreciated by the person skilled in the art.

[0069] The latch mechanism 5 is mounted on the arm 2 near its distal end relative to the nose 13. The stops 6 project from a principal side, i.e. a magazine mounting side 20, of the arm 2 and are distributed along the axis Ai of the arm 2. Each stop 6 includes a stop surface 60 which is substantially perpendicular to the axis Ai of the arm 2.

[0070] In this example, the stops 6 and 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 ribs 62 which extend from the wall 61 along the axis Ai of the arm 2 on the opposite side of the wall 61 to the stop surface 60.

[0071] The latch mechanism 5, illustrated more clearly in [Fig.4], includes a button 50 mounted on the arm 2 by a leaf spring 51. The button 50 is generally L-shaped, with an actuating portion 52 extending along the axis Ai of the arm 2, and a locking portion 53 substantially perpendicular to the actuating portion 52.

[0072] The actuating portion 52 includes a grooved actuating surface 52a which is inclined towards the locking portion 53. The locking portion 53 has a lip 54 for engaging the magazine 4 in order to retain it against the arm 2. The leaf spring 51 includes a mounting end 55 fixed to the arm 2 by a screw V, a curved connecting portion 56 captured by the locking portion 53 and a curved pivot portion 57 connecting the mounting end 55 to the curved connecting portion 56.

[0073] Thus, the actuation of the actuation part 52 rotates the button 50 relative to the arm 2 by elastically deforming the curved pivot part 57. The release of the actuation part 52 allows the button 50 to return to its initial, locked position.

[0074] The magazine 4, more clearly illustrated in Figures 5 and 6, comprises a plurality of fastening elements F, a fastening element outlet 40 at one end, and eyelets 41 on each side of the outlet 40. The magazine 4 also comprises a hooking element 42 projecting from one mounting side 43 of the magazine 4, towards a second end of the magazine 4, and three openings 44 in the mounting side 43 which are spaced along the length of the magazine 4 between the hooking element 42 and the exit 40.

[0075] The latching element 42 is substantially box-shaped with an open side describing a lip 45 at its free end and a pair of inclined sides 46 extending from the lip 45 and widening towards the mounting side 43 of the magazine 4. The lip 45 is designed to engage a part of the latching mechanism 5, for example the lip 54 thereof, with the latching element 42.

[0076] The magazine 4 is mounted on the drive tool 1 by inserting the pins 14 dependent on the nose 13 into the eyelets 41 of the magazine 4, the magazine 4 being slightly inclined relative to the mounting side 43 of the arm 2. In this position, the openings 44 of the magazine 4 are aligned with the stops 6 of the arm 2 and the button 50 is aligned with the hooking element 42.

[0077] When the magazine 4 is moved towards the mounting side 43 of the arm 2, the latching element 42 comes into contact with a ramp 58 of the locking part 53 of the button 50 and moves the button 50 away from its locking position, thus deforming the leaf spring 51. By continuing to push the magazine 4, the lips 45, 54 align and the button 50 returns to its locking position and engages in the latching element 42.

[0078] In this configuration, the button 50 presses the magazine 4 against the nose 13 to allow the nose 13 to be supplied with fastening elements F from the outlet 40 of the magazine 4. The link between the pins 14 dependent on the nose 13 and the eyelets 41 of the magazine 4 connects the magazine 4 to the nose 13 in a sliding manner.

[0079] When the driving tool 1 is pulled, the magazine 4 recoils by sliding along the arm 2, but the button 50 holds the magazine 4 against the arm 2 and absorbs part of the recoil force, until the stops 6 engage on an edge of the openings 44 to limit this sliding movement.

[0080] Figure 7 shows a magazine 104 according to another example similar to magazine 4 in Figures 5 and 6, where similar references represent similar features, incremented by 100. The magazine 104 in this example differs from that in Figures 5 and 6 in that it is shorter and contains fewer fastening elements F. However, this magazine 104 includes eyelets 141, a hooking element 142, and openings 144 similar to those of magazine 4 in Figures 5 and 6. It can therefore be mounted on the same drive tool 1 and operates similarly to that explained above.

[0081] Figure 8 shows a latch mechanism 105 according to another example similar to the latch mechanism 5 of Figure 4, where similar reference numerals represent similar features, incremented by 100. The latch mechanism 105 This example differs from that of [Fig.4] in that the button 150 pivots about an axis 157 and the latch mechanism 105 includes a pair of compression springs 151 which are compressible to allow the button 150 to pivot out of engagement with the magazine 4.

[0082] More specifically, the latch mechanism 105 includes a mounting bracket 155 fixed to the arm 2 by a screw V, and the button 150 is pivotally connected to it by the shaft 157. The mounting bracket 155 includes a reinforcement portion 159, which is parallel to the actuating portion 152, and the compression springs 151 are received between the actuating portion 152 and the reinforcement portion 159. The shaft 157 is located at the junction between the actuating portion 152 and the locking portion 153, so that actuation of the actuating portion 152 to compress the compression springs 151 causes the locking portion 153 to pivot out of its locked position. The subsequent release of the actuating part 152 causes the locking part 153 to return to its locked position, in a manner similar to the locking mechanism 5 described above.

[0083] A person skilled in the art will understand that the embodiments described above can vary in many ways. List of reference signs
