Description

TECHNICAL AREA

[0001] The present disclosure relates generally to a driving tool with a magazine that can be loaded with a large number of driving components. STATE OF THE ART

[0002] A driving tool for driving nails, for example into concrete, is configured such that a magazine loaded with driving components can be removed from the main body of the driving tool to remove a driving component if it becomes stuck in a nose section. JP 5 268 727 B2 discloses a driving tool configured such that a magazine can be attached by engaging an end region of the magazine in a feed direction with a nose region of the main body of the driving tool, thereby engaging a rear region of an actuating component of the magazine with the main body. The magazine can be removed from the main body by moving the actuating component to a release side and moving the rear region of the magazine in a release direction.

[0003] US 7,070,082 B2 discloses an insertion tool configured such that a magazine slides into engagement with a sliding base projecting laterally from a nose area of ​​the tool. The magazine is attached by engaging an actuating element on a rear side of the sliding base with a locking area on the rear of the magazine. The magazine is removed by moving the actuating element to a release side to disengage the locking area and move the magazine away.

[0004] The driving tools described above, disclosed in JP 5 268 727 B2 and US 7 070 082 B2, disclose that the magazine is removable by moving the actuating component to the release side and then moving the magazine in the removal direction. Therefore, the removal process is cumbersome because the user has to perform two actions. Thus, there is a need to improve the operability for removing the driving tool's magazine. BRIEF SUMMARY

[0005] The above-mentioned problem is solved by a driving tool according to claim 1.

[0006] According to one aspect of the present disclosure, an insertion tool comprises a tool body configured to drive in an insertion component and a magazine configured to be removablely attached to the tool body and to hold a number of insertion components. The insertion tool comprises a locking component configured to lock (secure) the magazine within the tool body such that it cannot be unlocked from the tool body, and an actuating component configured to move the locking component from a locked position to an unlocked position by actuating the actuating component. The insertion tool has an extrusion area formed at the actuating component.The extrusion area pushes the magazine in a distance direction relative to the main tool body by actuating the actuating component to move the locking component to the unlocking position.

[0007] Due to this configuration, when the actuating component moves the locking component to the unlocking position, the locking state of the magazine is released by the locking component, and the magazine is pushed through the extrusion area of ​​the actuating component in the removal direction. This movement improves the magazine's operability when it is removed. BRIEF DESCRIPTION OF THE DRAWINGS Fig. Figure 1 shows a side view of a driving tool.

[0008] The detailed description that follows, taking into account the attached drawings, is intended to be a description of exemplary embodiments of the present disclosure and is not intended to be limiting and / or to represent only the embodiments in which the present disclosure can be carried out. The term "exemplary," used throughout this description, means "serving as an example, application, or illustration" and should not necessarily be considered preferred or advantageous over other exemplary embodiments. The detailed description includes specific details for the purpose of providing a consistent understanding of the exemplary embodiments of the disclosure.It is evident to the person skilled in the art that the exemplary embodiments of the disclosure can be carried out without these specific details. In some applications, the specific details relate to known structures, components and / or devices shown in block diagram form to avoid obscuring significant aspects of the exemplary embodiments presented herein.

[0009] According to a further aspect of the present disclosure, the locking component and the actuating component are designed to be separate and movable within the main tool body. Due to this configuration, the actuating direction of the actuating component and the direction of movement of the locking component towards the unlocking position are different from each other, thereby locking the magazine more reliably in a compact configuration in the mounting position.

[0010] According to another aspect of the present disclosure, the insertion tool has a stop formed at the actuating component. The stop is configured to prevent the locking component from moving to the unlocking position and to allow the locking component to move to the unlocking position when the actuating component is actuated. Because of this configuration, the magazine can be more reliably locked in the mounting position by the stop.

[0011] According to a further aspect of the present disclosure, an actuation direction of the actuating component intersects both a loading direction of the drive components in the magazine and a drive direction of the drive component in the tool body. Due to this configuration, the magazine can be removed by actuating the actuating component in the lateral direction while the drive tool is being gripped.

[0012] According to a further aspect of the present disclosure, the locking component is rotatably mounted by the main tool body around a bearing shaft that extends parallel to an actuation direction of the actuating component. Due to this configuration, the actuating component and the locking component can be arranged in a compact manner.

[0013] According to another aspect of the present disclosure, the locking component and the actuating component are integrally formed and movable with respect to the main tool body. Accordingly, the configuration of the locking component and the actuating component can be simplified.

[0014] According to another aspect of the present disclosure, the locking component moves between the locked and unlocked positions by rotating the locking component. This configuration allows for improved remote operation of the magazine.

[0015] According to a further aspect of the present disclosure, the driving tool has a locking engagement area formed at the magazine and configured to contact (come into contact with) the extrusion area of ​​the actuating component. At least one of the extrusion area and the locking engagement area has an actuating force conversion surface, via which an actuating direction of the actuating component is converted to the removal direction of the magazine. Due to this configuration, the magazine is pushed in the removal direction by the actuating force of the actuating component.

[0016] According to another aspect of the present disclosure, the driving tool has a preloading component configured to preload the locking component in the direction of the locking position. A preloading force of the preloading component is also applied in the removal direction of the magazine. Due to this configuration, the magazine is pressed in the removal direction by the preloading force of the preloading component.

[0017] According to another aspect of the present disclosure, the insertion tool has a locking guide area and a locking recess, both formed in the magazine. The locking guide area slidably contacts the locking element when the magazine is attached to the tool body, and the locking recess is configured to engage with the locking element. When the magazine is removed from the tool body, the locking guide area is pressed by the locking element in the removal direction of the magazine due to the preload force of the preload element. Because of this configuration, the locking guide area functions effectively in both cases where the magazine is attached to and removed from the tool body.

[0018] According to a further aspect of the present disclosure, the driving tool has a structure in which the magazine is pushed in the removal direction by the actuation of the actuating component and the magazine is further pushed in the removal direction by the preload force of the preloading component as the locking component moves to the unlocking position. Due to this configuration, the magazine is removed from the main tool body via a first stage in which the magazine is pushed in the removal direction by the actuating component and a second stage in which the magazine is pushed in the removal direction by the preload force of the preloading component.

[0019] According to another aspect of the present disclosure, the driving tool has a nose formed on the main tool body, which extends in a driving direction of the driving component. The nose can be attached to the magazine. The magazine is pressed to one side of the nose when it is attached to the main tool body. Because of this configuration, the magazine can be attached to the nose without rattling.

[0020] According to another aspect of the present disclosure, the magazine is configured to be locked (secured) in an attachment position by the locking component when the magazine moves to one side of the tool body. Because of this configuration, the magazine can be attached to the tool body with a single movement.

[0021] One embodiment of the present disclosure is described below. Fig. Figures 1 to 3 show a gas spring-type driving tool as an example of a driving tool that uses gas pressure in a collecting chamber behind a cylinder as a thrust force for a driving component n. The following description specifies a direction for each component of the driving tool in a case where the driving tool 1 is held in such a position that a driving component n is driven into a workpiece W (wall surface), as shown in Fig. Figure 1 shows that a user of the driving tool 1 is generally located behind the driving tool 1. Fig. 1. The insertion direction of the insertion component n is forward, and a direction opposite to the forward direction is reverse. Up-down and left-right directions are based on the user's position.

[0022] As in Fig. As shown in Figure 1, the driving tool 1 has a main tool body 10. The main tool body 10 has a cylinder 12, which is received in a main body housing 11 and is generally cylindrical. A piston 13 is received in the cylinder 12 such that it is movable back and forth in a front-back direction. A driver 15 for driving in the driving component n is coupled to a front center of the piston 13. The driver 15 is a long (elongated) rod-shaped component that extends forward.

[0023] The main tool body 10 has a nose 20 located at a front region of the main tool body 10. The nose 20 has a drive passage 20a. A front region of the driveer 15 enters the drive passage 20a. The nose 20 also has a nose frame 21, which is coupled to the front of the main body housing 11, and a cylindrical ejection opening 22 that projects forward from the nose frame 21. The drive passage 20a passes through the nose frame 21 and the ejection opening 22 in a front-to-back direction. A drive component n, which is fed into the drive passage 20a, is driven in by the driveer 15. The drive component n, which is driven in (driven) by the driveer 15, is ejected from an end region of the ejection opening 22.

[0024] A rear section of the cylinder 12 behind the piston 13 is connected to the collecting chamber 14. The collecting chamber 14 is filled with a compressed gas, such as air. The gas pressure in the collecting chamber 14 acts on a rear surface of the piston 13 as a thrust force to move the piston 13 forward in the direction of travel.

[0025] The piston 13 and the drive element 15, which move in the driving direction due to gas pressure, are returned to a ready position in a rearward direction by a lifting mechanism 25. The lifting mechanism 25 is arranged such that it extends downwards from a front region of the main tool body 10. The lifting mechanism 25 has a lifting wheel 27, which is rotated by an electric motor 26. A motor shaft of the electric motor 26 and a rotational axis of the lifting wheel 27 are mutually coaxial and perpendicular to a direction of movement of the drive element 15, i.e., the forward-backward direction.

[0026] The driver 15 and the piston 13 are moved to the ready position in the rearward direction by rotating the lifting wheel 27, which engages with the driver 15, which is moved to a forward end by the driving operation. When the electric motor 26 is activated in the ready position, the driver 15 moves further in the rearward direction, thereby unlocking the lifting wheel 27 from the driver 15. As a result of this movement, the driver 15 moves forward to perform the driving operation.

[0027] A handle 5 is located behind the lifting mechanism 25 for the user to grip. The handle 5 extends downwards from a lateral area of ​​the main tool body 10. A switching lever 6 is located on an upper front surface of the handle 5 for the user to operate by pushing (pulling) it with their fingertips. When the switching lever 6 is pressed, a switch body 7 is activated, and the electric motor 26 of the lifting mechanism 25 is activated.

[0028] A control element 29, designed in a rectangular, flat shape, is arranged on the front of the lifting mechanism 25 and the electric motor 26. The control element 29 extends in the top-bottom direction. The lifting mechanism 25, the electric motor 26, and the control element 29 are housed in a lifting casing 28, which is designed in an approximately cylindrical shape.

[0029] A battery mounting area 8 is located on the bottom of the handle 5. As shown in Fig. As shown in Figure 1, a battery pack 9 can be attached to a lower surface of the battery mounting area 8. The battery pack 9 can be attached to and removed from the battery mounting area 8 by sliding the battery pack 9 in the front-back direction. Fig. 2 and Fig. Figure 3 shows the battery pack 9, which is located away from the battery mounting area 8.

[0030] Referring to Fig. 1 is a hook located on the left side of the front area of ​​the battery mounting area 8. When the driving tool 1 is not in use, the hook 2 can be attached, for example, to a user's waist belt for hanging the driving tool 1.

[0031] A front portion of the battery mounting area 8 is coupled to the lower portion of the lifting housing 28. The main body housing 11, the lifting housing 28, the handle 5, and the battery mounting area 8 are integrally formed together, resulting in a housing structure divided on the left and right.

[0032] The ejection opening 22 of the nose 20 is displaceable in the forward-backward direction within a certain range relative to the nose frame 21. When the ejection opening 22 contacts the workpiece W and the driving tool 1 is pressed in the driving direction, the ejection opening 22 moves backward relative to the nose frame 21 (activated state). In other words, when the driving tool 1 is pressed against the workpiece W, the ejection opening 22 moves backward into the "activated state," thus enabling the driving operation. A driving operation can be performed when the trigger lever 6 is pressed while the ejection opening 22 is in the activated state. This configuration prevents unintentional driving operations.

[0033] A magazine 30 can be detachably attached to the main tool body 10. The magazine 30 is coupled to the lower surface of the nose 20 via a magazine base 23. The magazine base 23 is arranged along the lower surface of the nose frame 21. An upper portion of the magazine 30 can be attached to the magazine base 23. Referring to Fig. The magazine 30 is primarily made of a drawn material, such as aluminum, and is rectangular in shape, extending in the top-bottom direction. The magazine 30 is located at the front of the lifting mechanism 25. A large number of drive-in components n, which are temporarily connected in parallel as a flat, plate-shaped connecting strip, are loaded into the magazine 30.

[0034] Referring to Fig. In section 5, a pusher 31 is arranged at the magazine 30. The pusher 31 has a feed claw 32, a regulating claw 36, and a coil spring 35. The feed claw 32 engages with a final drive component n on the connecting strip loaded in the magazine 30. Due to this configuration, the drive components n are pressed towards the drive passage 20a. The regulating claw 36 engages behind the ejection opening 22 when the remaining quantity of drive components n in the magazine 30 becomes small. Accordingly, the regulating claw 36 restricts rearward movement of the ejection opening 22, thus preventing a so-called "dry shot".

[0035] The pusher 31 is pre-tensioned in a feed direction (upwards) of the drive-in component n by the coil spring 35. An end section 35a of the coil spring 35 is hooked onto an upper section of the magazine 30. The drive-in components n of the connecting band are pressed by the pusher 31 towards the drive-in passage 20a. The drive-in components n are fed one after the other into the drive-in passage 20a of the nose 20 in conjunction with the drive-in process of the tool main body 10.

[0036] As in Fig. As shown in Figures 9 to 11, a loading hole 33 is formed in a lower area of ​​the magazine 30. The connecting strip of the drive-in components n can be loaded from the loading hole 33. As shown in Fig. As shown in Figure 5, the pusher 31 has a knob section 34. When the drive components n are loaded into the magazine 30, the pusher 31 can be moved downwards against the coil spring 35 using the knob section 34. During the downward movement of the knob section 34, the feed claw 32 can be retracted from an engagement position with the drive component n. As the pusher 31 moves downwards towards the connecting band of the drive components n, the feed claw 32 engages with the last drive component n. Due to this configuration, the drive component n loaded into the magazine 30 is pressed towards the drive passage 20a of the nose 20.

[0037] The magazine 30 is removable from the nose 20. This allows for the removal of a drive-in component n that is jammed in the nose 20. The magazine 30 has a front and a rear engagement area 30a and 30b on an upper region thereof. As in Fig. As shown in Figure 6, the magazine base 23 has a pair of magazine receiving areas 23a, 23b arranged along the front-back direction. The insertion passage 20a is open between the front and rear magazine receiving areas 23a and 23b. An insertion component n is fed into the insertion passage 20a through (between) the front and rear magazine receiving areas 23a and 23b.

[0038] The magazine 30 is coupled to the magazine base 23 by engaging the front engagement area 30a with the front magazine receiving area 23a and by engaging the rear engagement area 30b with the rear magazine receiving area 23b. When the magazine 30 is attached to the magazine base 23, an entire assembly of the magazine 30 is rotated rearward about the engagement area of ​​the front engagement area 30a relative to the front magazine receiving area 23a, as indicated by an unfilled arrow in Fig. 3 shown. Due to this movement, the rear engagement area 30b engages with the rear magazine receiving area 23b of the magazine base 23, whereby the magazine 30 is attached to the magazine base 23 in such a way that it is parallel to the lifting mechanism 25, which is in Fig. 1 and Fig. 2 is shown.

[0039] To remove the magazine 30 from the magazine base 23, the entire magazine 30 is rotated forward about the engagement area of ​​the front engagement area 30a in relation to the front magazine receiving area 23a, as indicated by the unfilled arrow in Fig. 3 shown. Due to this movement, the rear engagement area 30b moves away (detaches) from the rear magazine receiving area 23b of the magazine base 23, thereby moving the magazine 30 to a distance position as shown in Fig. 3 shown. Fig. Figure 3 shows that a rear side of the magazine 30 is further away from the lifting housing 28 as it extends downwards. The magazine 30 can be completely removed from the magazine base 23 by rotating the magazine 30 to the removal position.

[0040] The magazine 30 can be fixed to the magazine base 23 using a magazine locking area 40. The magazine locking area 40 has an actuating element 42 and a locking element 43, which is arranged on one side of the main tool body 10. The magazine locking area 40 also has a locking engagement area 44, which is arranged on one side of the magazine 30. The actuating element 42 and the locking element 43 are supported by a locking housing 41. The locking housing 41 is integrally formed with a lower portion of the lifting housing 28, thus ensuring compactness and structural stability. Similar to the lifting housing 28, the locking housing 41 has a left- and right-divided housing structure, comprising a right housing 41R and a left housing 41L, which abut each other.The locking engagement area 44 is located on the lower side of the magazine 30.

[0041] As in Fig. As shown in Figure 11, the right housing 41R of the locking housing 41 has a bearing rod 41a and a retaining rod 41b for guiding and supporting the movement of the actuating component. The bearing rod 41a is formed in an approximate prismatic shape. The retaining rod 41b is formed in an approximate cylindrical shape. The bearing rod 41a and the retaining rod 41b extend to the left parallel to each other. As shown in Fig. As shown in Figure 10, a rectangular retaining groove 42c and a circular retaining hole 42b are formed in a right-hand area of ​​the actuating component 42. The bearing rod 41a is positioned within the retaining groove 42c, and the actuating component 42 is mounted such that it is movable in the left-right direction between a locking side on the left and an unlocking side on the right.

[0042] As in Fig. As shown in Figure 11, a compression spring 45 is held by the retaining rod 41b. The retaining rod 41b and the compression spring 45 are held in the retaining hole 42b. The compression spring 45 biases the actuating component 42 in the direction of the locking side (to the left).

[0043] A rectangular prismatic actuation area 42a is formed on the left area of ​​the actuating component 42. As shown in Fig. 1 and Fig. As shown in Figure 6, a rectangular window 41c is formed in the left housing 41L of the locking housing 41. The actuating area 42a of the actuating component 42 projects outwards from the locking housing 41 through the window 41c. The user can place a fingertip on the actuating area 42a and push the actuating component 42 towards the unlocking side (to the right) against the preload force of the compression spring 45.

[0044] As in Fig. 9, Fig. 10 and Fig. As shown in Figure 12, a stop 42d is integrally formed on the right side of the actuating component 42. The stop 42d is arranged such that it extends in one direction towards the locking component 43. The stop 42d restricts the locking component 43 from moving towards the unlocking position. Accordingly, the locking component 43 does not rotate to the unlocking position until the actuating component 42 is pressed in the direction of the unlocking side. Therefore, even if the magazine 30 is pulled in the unlocking direction without pressing the actuating component 42 towards the unlocking side, the locked state of the magazine 30 cannot be released, since the locking component 43 cannot rotate to the unlocking position.

[0045] As in Fig. As shown in Figures 7 to 9 and 12, the actuating component 42 has an extrusion area 42f at its front region. The extrusion area 42f extends forward. The extrusion area 42f has an actuating force conversion surface 42e on its right side. The actuating force conversion surface 42e is inclined forward while extending to the left. As shown in Fig. As shown in Figure 12, the actuating force conversion surface 42e is formed, for example, by end surfaces of a plurality of ribs arranged in the top-bottom direction. In other words, the actuating force conversion surface 42e has end surfaces of a plurality of ribs. Alternatively, the actuating force conversion surface 42e can be modified to a single flat inclined surface.

[0046] As in Fig. As shown in Figure 11, a bearing shaft 41d is integrally formed with the right housing 41R of the locking housing 41. The bearing shaft 41d extends parallel to the bearing rod 41a, which supports the actuating component 42. The locking component 43 is mounted such that it is rotatable about the bearing shaft 41d in the up-down direction. The locking component 43 has a cylindrical bearing 43c approximately in the center of the locking component 43 in its longitudinal direction. The bearing shaft 41d engages an inner circumferential surface of the bearing 43c such that the locking component 43 is rotatably mounted by the bearing shaft 41d.

[0047] As in Fig. As shown in Figures 7 to 11, the locking component 43 has a locking area 43a at its front. The locking area 43a extends forward from the bearing 43c. One end of the locking area 43a is L-shaped and bent approximately upwards. Furthermore, the locking component 43 has an engagement area 43b at its rear. The engagement area 43b extends rearward from the bearing 43c.

[0048] A preload element 46 is received in the inner circumference of the bearing 43c. A torsion spring is used as the preload element 46. One end of the preload element 46 engages with the locking area 43a. The other end of the preload element 46 engages with the right housing 41R of the locking housing 41. Accordingly, the locking element 43 is preloaded in one direction by the preload element 46, so that the locking area 43a is displaced upwards, i.e., in a clockwise direction. Fig. 7 (in the direction of the locking position).

[0049] The engagement area 43b of the locking component 43 is biased downwards by the preloading component 46. The actuating component 42 is positioned above the engagement area 43b. When the actuating component 42 is positioned on the locking side, the stop 42d of the actuating component 42 is positioned on an upper side of the engagement area 43b, thus restricting the upward movement of the engagement area 43b. Due to this configuration, the locking component 43 is prevented from rotating to the unlocking position (counterclockwise). Fig. 7) restricted in contrast to the prestressing component 46.

[0050] As in Fig. As shown in Figure 8, when the actuating component 42 is pressed to the right, the stop 42d moves to the right with respect to the engagement area 43b of the locking component 43. Accordingly, the engagement area 43b of the locking component 43 is allowed to move upwards, and thus the locking component 43 is rotatable to the unlocking position.

[0051] The locking engagement area 44 is attached to the rear surface of the magazine 30. As shown in Fig. 6 and Fig. As shown in Figure 13, a locking window 41e is formed on the front surface of the locking housing 41. When the magazine 30 is attached or removed, the locking engagement area 44 moves in and out of the locking housing 41 through the locking window 41e.

[0052] Referring to Fig. 8, Fig. 9 and Fig. Figure 11 states that the locking engagement area 44 has a locking recess 44a, an actuating force conversion surface 44b, and a locking guide area 44c. The locking recess 44a and the locking guide area 44c are formed on the lower surface of the locking engagement area 44. The locking guide area 44c is formed on an adjacent area of ​​the rear side of the locking recess 44a. The actuating force conversion surface 44b is formed on the left side of the locking engagement area 44.

[0053] Fig. 4 and Fig. Figure 8 shows that the locking engagement area 44 enters the locking housing 41 through the locking window 41e when the magazine 30 is attached to the tool main body 10. Alternatively, it can be said that Fig. 4 and Fig. Figure 8 shows that the locking engagement area 44 is pulled out of the locking housing 41 through the locking window 41e to remove the magazine 30.

[0054] Before the magazine 30 is attached to the main tool body 10, the actuating component 42 is positioned to the left on the locking side by the preload force of the compression spring 45. When the locking engagement area 44 enters the locking housing 41, the actuating force conversion surface 44b of the locking engagement area 44 moves toward a right side of the actuating force conversion surface 42e of the actuating component 42. The actuating force conversion surface 44b of the locking engagement area 44 tilts to the right as it extends rearward.Due to this configuration, when the magazine 30 is attached to the main tool body 10, the actuating force conversion surface 44b slidably touches the actuating force conversion surface 42e of the actuating component 42, or lies parallel to the actuating force conversion surface 42e with a small gap between the two surfaces 44b and 42e.

[0055] Before the magazine 30 is attached to the main tool body 10, the locking element 43 is positioned by the preloading element 46 in an initial position that extends beyond the locking position. In the initial position of the locking element 43, the engagement area 43b is located downwards from the stop 42d of the actuating element 42. Accordingly, the locking element 43 can rotate towards the unlocking position.

[0056] When the locking engagement area 44 enters the locking housing 41 through the locking window 41e, the locking guide area 44c contacts the locking area 43a of the locking component 43, which is in the initial position. The locking guide area 44c is typically shaped as a circular arc surface inclined upwards as it extends rearwards, thus enabling it to guide the locking component 43 during insertion and removal. Because of this configuration, when the locking engagement area 44 enters the locking housing 41, the locking area 43a of the locking component 43 is pressed downwards by the locking guide area 44c. Consequently, the locking component 43 is rotated towards the unlocked position against the preload force of the preloading component 46.

[0057] When the locking engagement area 44 enters the locking housing 41, the locking component 43 rotates toward the unlocking position, thereby moving the locking area 43a relative to a front end region of the locking guide region 44c. As the locking engagement area 44 continues to enter the locking housing 41, the locking area 43a unlocks from the front end region of the locking guide region 44c. Accordingly, the locking component 43 is rotated toward the locking position by the preload force of the preload component 46, causing the locking area 43a to enter the locking recess 44a.

[0058] The rotational movement of the locking component 43 towards the locking position causes the locking area 43a to be drawn over a rear surface of the locking recess 44a, thereby drawing the locking engagement area 44 into the locking housing 41 by the preload force of the preload component 46. This movement holds the magazine 30 in the mounting position, as shown in Fig. 7 and Fig. Figure 11 shows that in this mounting position, upward movement of the engagement area 43b of the locking component 43 is restricted by the stop 42d of the actuating component 42. Accordingly, the locking area 43a is held in the locking recess 44a, and thus the magazine 30 is locked in the mounting position.

[0059] As in Fig. 4, Fig. 7, Fig. 8 and Fig. As shown in Figure 13, a triangular, column-shaped mounting guide area 41f is arranged between the actuating component 42 and the locking component 43. The mounting guide area 41f is integrally formed with the inner surface of the left housing 41L. The mounting guide area 41f is positioned approximately transversely across the right and left housings 41L and 41R of the locking housing 41. The mounting guide area 41f has a guide surface 41g on an upper region thereof. The guide surface 41g is inclined towards the nose 20 as it extends rearward.

[0060] During the mounting of the magazine 30, the locking guide area 44c of the locking engagement area 44 contacts the guide surface 41g of the mounting guide area 41f. As described above, the locking engagement area 44 is drawn into the locking housing 41 by the preload force of the preloading component 46, and thus the locking guide area 44c elastically contacts the guide surface 41g. Due to this configuration, the magazine 30 is guided towards the nose 20 (the nose frame 21).

[0061] The magazine 30 is attached to the nose 20 by the preload force of the preloading component 46, which reduces the gap between the magazine base 23 and the magazine 30, thus preventing the magazine 30 from rattling.

[0062] When the magazine 30 is removed, the actuating component 42 is pressed. (Referring to) Fig. 9 and Fig. 10. When the actuation area 42a of the actuating component 42 is pressed to the right, the stop 42d moves away from above the engagement area 43b of the locking component 43. This movement allows the locking component 43 to rotate to the unlocked position. When the actuating component 42 is pressed, the actuation force conversion surface 42e is pressed against the actuation force conversion surface 44b of the locking engagement area 44. Accordingly, the actuation force of the actuating component 42 is converted into a force in a direction that pushes (pulls) the locking engagement area 44 out of the locking housing 41 (in a direction of removal of the magazine 30).

[0063] When the locking engagement area 44 is pressed in the removal direction, the locking area 43a is pressed against the rear surface of the locking recess 44a, thereby rotating the locking component 43 towards the unlocking position. When the actuating component 42 is pressed towards the unlocking side (as in Fig. (as shown in Figure 8), the locking engagement area 44 moves in the removal direction, and the locking component 43 continues to rotate towards the unlocking position. Due to this movement, the locking area 43a is moved away from (out of) the locking recess 44a to reach a front end of the locking guide area 44c.

[0064] The magazine locking area 40 is in an unlocked state when the locking area 43a is removed from the locking recess 44a. When the locking area 43a is removed from the locking recess 44a, the locking area 43a is pressed against the locking guide area 44c by the preload force of the preloading element 46 via the locking engagement area 44. The preload force of the preloading element 46 acts as a force to displace the magazine 30 in the removal direction via the locking engagement area 44. Accordingly, the magazine 30 is pushed in the removal direction.In this way, the magazine 30 is removed from the locking engagement area 44 via a first stage, in which the magazine 30 moves in the removal direction by the pushing movement of the actuating component 42, and a second stage, in which the magazine 30 is pressed in the removal direction by the preload force of the locking component 43 of the preloading component 46.

[0065] According to the first embodiment described above, when the actuating component 42 moves the locking component 43 from the locked position to the unlocked position, magazine removal is enabled, the locked state of the magazine 30 by the locking component 43 is released, and the magazine 30 is pushed through the extrusion area 42f of the actuating component 42 in the removal direction. This movement improves the operability of the magazine 30 when it is removed.

[0066] According to the first embodiment, the locking component 43 and the actuating component 42 are designed such that they are movable separately and within the locking housing 41 of the main tool body 10. Due to this configuration, the actuating direction of the actuating component 42 and the direction of movement of the locking component 43 towards the unlocking position are different from each other, which allows the magazine 30 to be locked more reliably in the mounting position with a compact configuration.

[0067] According to the first embodiment, the actuating component 42 has a stop 42d to restrict the movement of the locking component 43 to the unlocking position. The stop 42d allows the locking component 43 to move to the unlocking position by actuating the actuating component 42. Due to this configuration, the magazine 30 can be locked more reliably in the mounting position by the stop 42d.

[0068] According to the first embodiment, both the extrusion area 42f of the actuating component 42 and the locking engagement area 44 of the magazine 30, which contacts the extrusion area 42f, have actuating force conversion surfaces 42e and 44b, which convert the actuating direction of the actuating component 42 to the removal direction of the magazine 30. Accordingly, the magazine 30 is pushed in the removal direction by the actuating force of the actuating component 42.

[0069] According to the first embodiment, the actuation direction of the actuating component 42 intersects the direction in which the magazine 30 extends (the up-down direction) and the driving direction of the tool main body 10 (the front-back direction). Due to this configuration, the magazine 30 can be removed by actuating the actuating component 42 laterally from the left side while gripping the driving tool 1.

[0070] According to the first embodiment, the locking component 43 is mounted around the bearing shaft 41d by the locking housing 41 of the main tool body 10, the bearing shaft extending in the actuation direction of the actuating component 42. The locking housing 41 is a structural component within the main tool body 10 that accommodates the locking component 43 and the actuating component 42. This configuration allows the actuating component 42 and the locking component 43 to be arranged in a compact manner.

[0071] According to the first embodiment, the driving tool 1 has the preloading component 46 for preloading the locking component 43 in the direction of the locking position, and the preloading force of the preloading component 46 also acts in the removal direction of the magazine 30. Due to this configuration, the magazine 30 is pressed in the removal direction by the preloading force of the preloading component 46.

[0072] According to the first embodiment, the magazine 30 has the locking guide area 44c and the locking recess 44a. The locking guide area 44c slides relative to the locking component 43, and the locking component 43 engages with the locking recess 44a when the magazine 30 is attached to the locking housing 41. When the magazine 30 is removed from the locking housing 41, the locking guide area 44c is pressed in the removal direction by the locking component 43, which is biased by the biasing force of the biasing component 46. Due to this configuration, the locking guide area 44c functions effectively in both cases, when the magazine 30 is attached to or removed from the locking housing 41.

[0073] According to the first embodiment, the magazine 30 is pushed in the removal direction by actuation of the actuating element 42, and the magazine 30 is further pushed in the removal direction by the preload force of the preloading element 46 when the locking element 43 moves to the unlocking position. Due to this configuration, the magazine 30 is removed from the main tool body 10 via a first stage, in which the magazine 30 is pushed in the removal direction by the actuating element 42, and a second stage, in which the magazine 30 is pushed in the removal direction by the preload force of the second preloading element 46.

[0074] According to the first embodiment, the main tool body 10 has a nose 20 to which the magazine 30 is attached and which extends in the direction of insertion. The main tool body 10 also has an attachment guide area 41f, which guides the magazine 30 towards the nose 20 when the magazine 30 is attached to the nose 20. Because of this configuration, the magazine 30 can be attached to the nose 20 without rattling.

[0075] According to the first embodiment, the magazine 30 is locked in the mounting position by the locking component 43 when the magazine 30 moves (is moved) to one side of the tool body 10. Because of this configuration, the magazine 30 can be attached to the tool body 10 with a single movement.

[0076] Various modifications can be made to the driving tool 1 of the first embodiment. In the embodiment described above, the actuating component 42 is biased towards the locking side by the compression spring 45. However, a leaf spring can be used instead of the compression spring 45.

[0077] In the embodiment described above, the actuation area 42a of the actuating component 42 is arranged on the left side of the locking housing 41. Alternatively, the actuation area 42a can be arranged on the right side of the locking housing 41.

[0078] Both or one of the actuating force conversion surface 42e of the actuating component 42 and the actuating force conversion surface 44b of the locking engagement area 44 can be formed in a curved surface shape.

[0079] In the embodiment described above, the locking guide area 44c is designed such that it has a circular arc surface. Alternatively, the locking guide area 44c can be designed as an inclined surface or a curved surface.

[0080] Fig. Figures 14 to 16 show a magazine locking area 50 according to a second embodiment. Descriptions of components and configurations that do not require modification and are common to the first embodiment are omitted by using the same reference numerals. The magazine locking area 50 of the second embodiment has a locking component 51 that is supported by a locking housing 41 of the main tool body 10. The locking component 51 is manufactured as a single component and integrally comprises an actuating lever 52, a locking arm 53, a stop 54, and an extrusion area 55. The second embodiment differs from the first embodiment in that the actuating component 42 and the locking component 43 are separate components in the first embodiment that can be moved in different directions relative to each other.

[0081] The locking component 51 is rotatably mounted about a bearing shaft 56 in the right housing 41R. The locking component 51 is rotatable about the bearing shaft 56, the axis of which intersects both the feed direction of the drive component n in the magazine 30 and the drive direction of the drive component n in the main tool body 10 (perpendicular to these). The locking component 51 rotates in a clockwise direction. Fig. 15 and Fig. 16 is pre-tensioned by a pre-tensioning force of the pre-tensioning component 57, which is held around the bearing shaft 56. The actuating lever 52, the locking arm 53, the stop 54 and the extrusion area 55 are arranged at approximately four equally spaced positions around the bearing shaft 56.

[0082] The actuating lever 52 extends downwards in relation to the bearing shaft 56. As shown in Fig. As shown in Figure 14, a rectangular window 58 is formed on the lower surface of the locking housing 41. The window 58 is formed on the left housing 41L. An end portion of the actuating lever 52 extends downwards from the locking housing 41 through the window 58. As shown in Fig. As shown in Figure 15, when the locking component 51 is on a locking side, the actuating lever 52 is in a locking position, in which the actuating lever 52 extends downwards from the window 58. On the other hand, when the locking component 51 is on an unlocking side, as shown in Figure 15, the actuating lever 52 is in a locking position, in which the actuating lever 52 extends downwards from the window 58. Fig. As shown in Figure 16, the actuating lever 52 is in an unlocked position, in which the actuating lever 52 extends obliquely downwards and rearwards from the window 58. The actuating lever 52 can be rotatably actuated from the outside of the locking component 51 within a range of approximately 45° between the locked and unlocked positions.

[0083] The locking arm 53 extends forward with respect to the bearing shaft 56. Similar to the locking component 43 in the first embodiment, one end of the locking arm 53 is formed in an L-shape that bends approximately upwards. Similar to the first embodiment, the tip end of the locking arm 53 engages with the locking engagement area 61 of the magazine holder 60 for locking the magazine 30. The locking engagement area 61 has a locking recess 61a on its lower surface in the same manner as in the first embodiment. As in Fig. As shown in Figure 15, the end region of the locking arm 53 enters the locking recess 61a for engagement with the locking engagement area 61.

[0084] The stop 54 extends rearward with respect to the bearing shaft 56. A stop receiving area 59 is formed on an inner surface of the right housing 41R. As shown in Fig. As shown in Figure 15, when the locking component 51 is located on the locking side, the stop 54 contacts the stop receiving area 59 from above by a preload force of the preload component 57. Accordingly, it is prevented that the locking component 51 rotates in the clockwise direction (further rotation towards the locking side).

[0085] The extrusion area 55 extends upwards with respect to the bearing shaft 56. The extrusion area 55 corresponds to the extrusion area 42f of the first embodiment. Similar to the first embodiment, an actuating force conversion surface 55a is formed on the right side of the extrusion area 55. When the magazine 30 engages with the locking element 51, the actuating force conversion surface 55a contacts the locking engagement area 61 of the magazine holder 60. Similar to the first embodiment, an actuating force conversion surface 61b is formed on the left side of the locking engagement area 61. When the magazine 30 engages with the locking element 51, the actuating force conversion surface 61b contacts the actuating force conversion surface 55a of the extrusion area 55.

[0086] Similar to the first embodiment, the locking engagement area 61 is arranged on a lower region of the magazine 30 and extends rearward. The locking engagement area 61 is integrally formed with a magazine holder 60. Likewise, a holder 62 is integrally formed with the magazine holder 60. The locking engagement area 61 is located on a rear region of the holder 62. The holder 62 extends forward from the locking engagement area 61 to a front region 62a through a right side of the magazine 30. The front region 62a of the holder 62 is attached to the front end region of the magazine 30 by a fixing screw 63.

[0087] A rear portion of the holder 62 is firmly held to the magazine 30 by means of a metal clip 65. The clip 65 has a U-shaped clamping area 65a. The clamping area 65a elastically holds the rear portion of the holder 62 and the rear portion of the magazine 30. Due to this configuration, the holder 62, specifically a rear portion of the holder 62, firmly holds the magazine 30.

[0088] An extension area 65b is integrally formed on a rear area of ​​the clamping area 65a of the clip 65. The extension area 65b is screw-fixed to a left-hand side area of ​​the locking engagement area 61 by means of a fixing screw 64. Accordingly, the clip 65 is firmly attached to the locking engagement area 61. The clip 65 increases the load-bearing capacity (bearing stiffness) of the locking engagement area 61 with respect to the magazine 30.

[0089] Similar to the first embodiment, a triangular, column-shaped mounting guide area 66 is formed between the locking component 51 and the locking engagement area 61. The mounting guide area 66 is integral with an inner surface of the left housing 41L. A guide surface 66a is formed on an upper region of the mounting guide area 66. When the magazine 30 is attached to the locking housing 41, the locking engagement area 61 contacts the guide surface 66a and is guided upwards, thereby pressing the magazine 30 towards the nose 20. Due to this configuration, the magazine 30 is attached to the magazine base 23 without rattling, and thus a drive component n is easily fed to the drive passage 20a.

[0090] As in Fig. As shown in Figure 15, in the locked state of the magazine locking area 50, the end region of the locking arm 53 enters the locking recess 61a of the locking engagement area 61. The actuating force conversion surface 55a of the extrusion area 55 contacts the actuating force conversion surface 61b of the locking engagement area 61. The stop 54 contacts the stop receiving area 59.

[0091] The magazine 30 is attached to the main tool body 10 without rattling by engagement of the locking arm 53 and the extrusion area 55 of the locking component 51 with the locking engagement area 61, which has a high load-bearing capacity, using the clip 65.

[0092] When the magazine 30 is removed from the tool body 10, the actuating lever 52 is rotated to the unlocking position (towards the rear), as shown in Fig. 16 shown. The actuating lever 52 is rotated to the unlocking position against the preload force of the preloading component 57. When the locking component 51 rotates counterclockwise, as shown in Fig. As shown in Figure 16, the locking arm 53 is pulled out of the locking recess 61a. Likewise, the locking engagement area 61 is pushed forward through the extrusion area 55. The locking engagement area 61 is pressed by the rotary actuation force of the actuating lever 52.

[0093] By rotating the actuating lever 52, the locking arm 53 is unlocked from the locking recess 61a, and the locking engagement area 61 is also pressed through the extrusion area 55. This movement pushes the magazine 30 forward to be removed from the main tool body 10. When the actuating lever 52 is released on the unlocking side, and the magazine 30 is removed from the main tool body 10, the actuating lever 52 rotates clockwise. Fig. 16 by the preload force of the preloading component 57 to return to the initial position beyond the locking position.

[0094] To attach the magazine 30 to the main tool body 10, it is sufficient to rotate the magazine 30 backward while its upper portion engages the magazine base 23. As the magazine 30 rotates backward, the locking engagement area 61 enters the locking housing 41. The tip of the locking arm 53 contacts the lower surface of the locking engagement area 61 within the locking housing 41. As the locking engagement area 61 further enters the locking housing 41, with the locking engagement area in contact with the tip of the locking arm 53, the locking element 51 rotates counterclockwise from its initial position against the preload force of the preload element 57.After the tip of the locking arm 53 touches the lower surface of the locking engagement area 61 and is guided downwards, the locking arm 53 enters the locking recess 61a. When the locking arm 53 enters the locking recess 61a, the locking engagement area 61 is further drawn into the locking housing 41 by the preload force of the preloading component.

[0095] By pulling the locking component 51, the locking engagement area 61 is pressed to the right through the actuating force conversion surface 55a of the extrusion area 55. Simultaneously, the locking engagement area 61 contacts the guide surface 66a of the mounting guide area 66. This movement causes the locking engagement area 61 to move upwards. The actuating lever 52, together with the locking arm 53 and the extrusion area 55, returns to the locking position due to the preload force of the preloading component 57. When the actuating lever 52 has returned to the locking position and the locking arm 53 enters the locking recess 61a of the locking engagement area 61, the magazine 30 is locked in the mounting position.

[0096] According to the magazine locking area 50 in the second embodiment described above, when the actuating lever 52 is rotated to the unlocking position, the magazine 30 is released from the locked state by the locking arm 53 and is pushed through the extrusion area 55 in the removal direction. This configuration improves the remote operability of the magazine 30.

[0097] In the second embodiment, the locking component 51 is integrally formed with the actuating lever 52, the locking arm 53, the extrusion area 55 and the stop 54, thereby simplifying the configuration of the magazine locking area 50.

[0098] In the first and second embodiments, a gas spring-type driving tool is represented as driving tool 1. However, the magazine locking areas 40 and 50 can be applied, for example, to a pneumatic driving tool driven by externally supplied compressed air, a mechanical spring driving tool that uses the thrust force of a compressed spring as the driving force, or an electric driving tool of the radar type.
