Description

Field of the invention

[0001] The invention relates to a driving tool and a driving screw stop tool. Background and general description of the invention

[0002] The technical field of fastening technology is constantly evolving. Portable devices, especially those used to drive fasteners into a structure, are available in a wide variety of models and are used in tough, continuous applications. It can be tedious to consistently set up a consistent screw connection, especially when large objects need to be fastened, or when the same type of fastening is required using the same fasteners, such as repetitive screw connections.

[0003] This description also deals with reducing the working time required to drive in a fastener, as well as with reducing sources of error and reducing the potential error rate in order to provide an even more satisfactory result for the user.

[0004] Specifically, the present invention solves a still existing problem in a particularly elegant way of providing a uniform connection quality for a large number of similar screw connections.

[0005] One object of the present invention can therefore be seen as providing an improved device for driving fasteners into a workpiece or a surface. In one aspect of the present description, the aforementioned problems and challenges are solved or improvements thereto are presented.

[0006] The object of the invention is solved by the subject matter of the independent patent claims. Dependent claims represent further developments.

[0007] A driving screw stop tool for a driving tool according to the present invention has a drive that can be driven by the driving tool and a tool holder for receiving a driving tool or a connector, designed to drive the connector into a workpiece until a screw stop condition is reached. A frequently used example of a connector is a screw. A driving tool or tool is, for example, a screwdriver bit arranged or arrangeable in the device, which can be inserted into a corresponding holder in order to be precisely inserted into fastener heads. A prominent example of this is a Torx or Philips screwdriver. If necessary, the driving screw stop tool can be designed so that the connectors can be inserted directly into the driving screw stop tool, i.e., without the use of a separate tool.This can be advantageous if you don't intend to use different fastener heads, but always screw in heads of the same type. The use of an interchangeable tool is known, particularly using different screwdriver bits, with which, in one example, Torx screws size 20 can be driven first and, after changing the tool, Philips screws size PH2 can be driven in a subsequent step using the same driving screw stop tool.

[0008] The driving screw stop tool is designed to automatically stop driving when the screw stop condition is reached. The screw stop condition can be, for example, that the fastener head comes into contact with the workpiece or is sunk a predefined depth into the workpiece. In a particularly interesting case, a sealing element is arranged on the fastener. The sealing element can be arranged on the shank of the fastener to be driven, below the fastener head, so that the sealing element seals the screw hole when the fastener is driven in. Such a sealing element can exert the sealing effect when it is clamped sufficiently tightly by the fastener head to the workpiece, but not too tightly, so that the sealing element is not damaged by the connector or displaced outwards by the fastener head.In other words, the fastener must not be screwed too far into the workpiece, but also not too loosely so that the sealing element can develop its full sealing effect.

[0009] The screw stop condition can, for example, be the screw-in depth of the connector. The screw stop condition can also be the distance of the fastener head from the workpiece – this is particularly interesting in the case of the sealing element arranged below the fastener head. In other words, a distance of the head from the workpiece can be set as a condition, so that screwing in the fastener automatically stops at the set distance. The set distance can, for example, correspond to a thickness of the sealing element, or can correspond to a thickness that corresponds to a compressed sealing element. In other words, the condition, i.e. the set distance, can correspond to the thickness of the sealing element less a compression allowance.

[0010] The screw stop condition can be adjusted using an adjustable screw stop. In other words, the moment at which the screw stop condition is reached can be set. This is advantageous when different sealing elements or connectors are being processed, and a different screw stop should be adjustable depending on the type of sealing element or connector. For example, one type of sealing element can be thicker, or one type of sealing element can be pressed more tightly against the workpiece than another type of sealing element, which would already shear off under such pressure or would not achieve the optimal sealing effect. For example, setting the screw stop condition can be adjusted by adjusting the screwing of the connector head so that the connector head is positioned more or less tightly against the workpiece before the screw stop condition is triggered.For example, the screw stop condition, in particular the distance of the connector head from the workpiece, can be adjustable in individual steps, for example in individual steps of 1 / 8 mm each, or 1 / 10 mm each, or 1 / 12 mm each, or comparable.

[0011] A depth adjustment can be included for adjusting the screw stop. In other words, the depth adjustment can be used to set the time or depth at which the screw stop condition is met and the driving process automatically ends. In a preferred embodiment, the depth adjustment can comprise a screw stop sleeve. Alternatively or additionally, the depth adjustment can comprise a manipulable adjustment sleeve. Further alternatively or additionally, the depth adjustment can comprise an adjusting element, in particular a compressible adjusting element such as a helical spring, for adjusting the manipulable adjustment sleeve against the screw stop sleeve.

[0012] The screw stop sleeve can preferably be connected to the drive so that the screw stop sleeve rotates with the drive when the drive is moved. For example, the drive is typically driven by the driving tool, so that the screw stop sleeve rotates when the driving tool is in operation. Alternatively or additionally, the screw stop sleeve can have at least one inner driver for rotatingly driving the manipulable adjustment sleeve on the screw stop sleeve. Such a driver is preferably arranged on the inside, which advantageously eliminates the risk of injury when the screw stop sleeve rotates. A driver can be designed, for example, as a retaining lug, toothing, locking element, or rotating system.

[0013] The manipulable adjustment sleeve can have an external finger rest. Such a finger rest is designed to simplify adjustment of the tool, thus it is an adjustment handle. For example, the finger rest is designed as a constriction on the outside of the adjustment sleeve.

[0014] Alternatively or additionally, the manipulable adjustment sleeve can have at least one counter-driver. The counter-driver is designed to cooperate with the driver of the screw stop sleeve.

[0015] In other words, the counter-driver engages with the driver or coacts with the driver in such a way that when the screw stop sleeve is rotated by means of the driver and via the counter-driver, the adjustment sleeve also rotates.

[0016] Alternatively or additionally, the manipulable adjustment sleeve can have at least one adjustment stop. The adjustment stop can also be arranged on the screw stop sleeve. For example, the adjustment stop can be designed to limit an adjustment range of the adjustment sleeve. In other words, the adjustable depth adjustment can be configured such that the screw stop condition is adjusted by adjusting the adjustment sleeve in the axial direction along the driving screw stop tool. For example, this can be used to shorten or lengthen the adjustment path for the tool holder via which the connector is driven in, or to determine when the connector is no longer automatically driven in by the driving screw stop tool.

[0017] The adjustment element can preferably be designed to position the adjustment sleeve against the screw stop sleeve over the entire adjustment range of a closed position of the depth adjustment. In a closed position of the depth adjustment, the manipulable adjustment sleeve can be positioned or held against the screw stop sleeve, for example in the direction of the driving tool. Furthermore, the adjustment sleeve can be designed to be rotationally fixed relative to the screw stop sleeve in the closed position. This can be configured such that it is "carried along" by the screw stop sleeve during a rotational movement. Alternatively or cumulatively, in an adjustment position of the depth adjustment, the manipulable adjustment sleeve can be positioned away from the screw stop sleeve, for example in the direction of the tool holder or tool. In the adjustment position, the adjustment sleeve is preferably rotatable relative to the screw stop sleeve.

[0018] Thus, rotating the adjustment sleeve relative to the screw stop sleeve can cause the depth adjustment to be adjusted. In other words, the screw stop can be configured to cause the depth adjustment to be adjusted by rotating the adjustment sleeve relative to the screw stop sleeve in the adjusted position. To adjust the depth adjustment, simply move the adjustment sleeve away from the screw stop sleeve or push it away, after which the screw stop can be adjusted.

[0019] Furthermore, the screw stop can include a tamper-proof device to at least temporarily prevent any adjustment of the depth adjustment. The tamper-proof device can be designed to be pluggable, so that it is, for example, plugged or clipped onto the adjustment sleeve to prevent movement of the adjustment sleeve. The tamper-proof device can be designed as a plug-on ring or as a partial ring element. Alternatively, the adjustment sleeve can also include the tamper-proof device, for example, in the form of a fold-out stop.

[0020] The driving screw stop tool can further comprise a front-side contact element for contact with the workpiece. The contact element can be bell-shaped. The contact element can have a contact element sliding bearing, so that the contact element can rotate freely relative to the drive. For example, this can make it possible to grip the contact element by hand during use. The contact element can be designed to cover a front part of the driving screw stop tool. For example, the contact element can also cover part of the mechanism, so that it is protected from interference or damage. Furthermore, the front-side contact element can have a protective ring on the workpiece side. The protective ring can be designed to protect the contact element and, if necessary, can also be slightly compressible, so that a certain tolerance is created against an oblique application of the driving tool.

[0021] Preferably, a decoupler is also included for decoupling the tool holder from the drive. In other words, the decoupler can be used to mechanically separate the workpiece side from the driving tool side. Further driving of the driving screw stop tool from the driving tool in the decoupled state will then no longer result in any rotational movement of the workpiece side.

[0022] The driving screw stop tool can also be configured so that when the tool is positioned against the workpiece, the contact element comes into contact with the workpiece at or before a screw-in depth set by the screw stop is reached, triggering the screw stop. In other words, positioning the contact element against the workpiece can trigger the screw stop or prepare for the screw stop to be triggered.

[0023] When the contact element is applied to the workpiece and the driving in of the connector continues, the uncoupler in particular can automatically detach the tool holder from the drive. In an exemplary embodiment, the driving screw stop tool is always decoupled as long as it is not applied to a workpiece. If the driving screw stop tool is applied to a workpiece or a surface, a contact force on the workpiece or the connector inserted into the driving screw stop tool can convert the uncoupler into a coupled state, for example by a workpiece side of the uncoupler engaging with a driving tool side of the uncoupler. When the connector is driven far enough into the workpiece or the surface, the contact element comes into contact with the workpiece or surface, so that the driving screw stop tool can no longer be applied to the workpiece.However, the connector and the workpiece side of the uncoupler continue to engage as the driving tool is continuously operated, causing the connector to be driven further into the workpiece. The workpiece side of the uncoupler thus moves progressively away from the driving tool side of the uncoupler, causing the two sides of the uncoupler to separate from each other. When the predefined or preset driving depth is reached, the uncoupler is released and separates the tool holder from the drive. This prevents further driving of the connector.

[0024] The present description also shows a driving tool, in particular a cordless screwdriver, which has a driving tool body, and which is characterized by a combined driving and screw stop tool connected to the driving tool, in particular as described above, for driving connectors such as screws until a screw stop condition is reached, at which the driving operation automatically ends. The driving tool can have a tool holder arranged in or on the driving tool body; in this case, the driving and screw stop tool can be connected to the tool holder.

[0025] The present description further includes a method for driving a connector by means of a driving device as described above or with a driving screw stop tool as described above, and comprising the steps of inserting a tool or a connector into the tool holder of the driving screw stop tool, driving the connector into a workpiece by means of the driving screw stop tool until the screw stop condition is reached, at which the driving automatically ends.

[0026] Before reaching the screw stop condition, the step of applying a contact element of the driving screw stop tool to the workpiece can be performed, and driving the connector can be continued after the contact element has been applied to the workpiece. Alternatively or cumulatively, the step of setting the screw stop condition, in particular the screw-in depth, can be performed using an adjustment.

[0027] Preferably, a driving axis is formed from a driving tool drive to the fastening means arranged on the front, wherein the driving axis extends through the driving screw stop tool. For example, the driving axis intersects the driving screw stop tool centrally or along the force transmission axis. The fastening means are, in particular, screw means. Alternatively or cumulatively, the driving tool is a screw tool. The driving tool is preferably a screw tool, designed for rotatingly driving the screw means into a workpiece or a surface. The driving screw stop tool can be formed as a single piece or integrally with the driving tool.

[0028] In the following, the invention is described in more detail using exemplary embodiments and with reference to the figures, wherein identical and similar elements are partly provided with the same reference numerals and the features of the various exemplary embodiments can be combined with one another. Short description of the characters

[0029] It shows: Fig. 1 Side view of an embodiment of a driving screw stop tool, Fig. 2 side sectional view of an embodiment of a driving screw stop tool, Fig. 3 Exploded view of an embodiment of a driving screw stop tool, Fig. 4 Side view of another embodiment of a driving screw stop tool, Fig. 5 perspective view of an embodiment of a driving screw stop tool, Fig. 6 Side view of a driving tool with the driving screw stop tool inserted. Detailed description of the invention

[0030] The Fig. 1 shows a side view of a driving screw stop tool 10, which is designed to screw connectors 90 into a workpiece 70 until a screw stop condition is reached. A drive 30 of the driving screw stop tool 10 can be connected to a driving device 80 (cf. Fig. 6) are coupled so that the tool 10 is driven by the driving device 80. The driving screw stop tool 10 has a depth adjustment 8, by means of which the screw stop condition can be adjusted. In particular, this can be used to set a screw-in depth for the connector 90 at which the driving screw stop tool 10 automatically terminates the driving process.

[0031] The depth adjustment 8 has a screw stop sleeve 12 and an adjustment sleeve 14. Using the finger rest 16, the adjustment sleeve 14 can be grasped and moved laterally along the drive axis 60 toward the workpiece side 11. This moves the depth adjustment 8 from the closed position to the adjustment position. In the adjustment position, the adjustment sleeve 14 can be adjusted relative to the screw stop sleeve 12, i.e., it can be rotated while the screw stop sleeve 12 remains stationary.

[0032] The driving screw stop tool 10 further comprises a contact element 18, which is designed to be applied to a workpiece 70. Furthermore, the contact element 18 is connected to the housing element 22, which together house the front part 11 of the mechanism of the driving screw stop tool 10. The entire section consisting of the contact element 18 via the constriction 20 and the housing element 22 is rotatably arranged or mounted so that this part can be held in place during operation, for example, when driving in a connector 90, and thus the entire driving tool 80 can be supported. Nevertheless, the depth adjustment 8 is secured in the closed position and cannot be accidentally adjusted during operation. This enables very convenient and comfortable handling of the tool without inadvertently changing the depth adjustment 8 and thus the screw stop condition.Furthermore, a protective element 24, for example a plastic cap, is arranged on the front side 11 for a softer placement of the contact element 18 on a workpiece 70 or for protecting the contact element 18.

[0033] In all embodiments shown, the same reference numerals also represent the same features, so that the features of the embodiments shown in the individual figures can be combined with one another and the feature described for one figure also applies to another figure, unless otherwise highlighted.

[0034] Referring to the Fig. 2 shows a sectional view of a driving screw stop tool 10, clearly showing the internal mechanism. The adjusting sleeve 14 is adjusted by the adjusting element 26 against the screw stop sleeve 12 into the closed position, which is also shown here. The adjusting element 26 is implemented here as a spring element, which exerts a preload force on the adjusting sleeve 14 and adjusts it laterally along the driving axis 60 in the direction of the drive 30 against the screw stop sleeve 12. In this case, the adjusting element 26 is supported against a projection of the housing element 22. The projection of the housing element 22, in turn, encloses the stop piece 34. In this example, the stop piece 34 is formed integrally with the drive 30. An axis 42 is arranged, which drives the workpiece-side part 40 of the uncoupler 45 in the coupled state.For this purpose, the axle engages in axle receptacles 48 arranged on the front part 40 of the uncoupler 45. To engage, the drive side with axle 42 is rotated by 90° in the embodiment shown, so that in the embodiment shown, it is possible to engage in both axle receptacles 48. It is also conceivable to provide a total of four axle receptacles 48, each arranged at a 90° angle to one another, instead of two axle receptacles 48, in order to further simplify the coupling of the uncoupler 45.

[0035] On the workpiece side, the part 40 of the decoupling 45, there is also a tool holder or connector holder 38, into which either a tool (for example a screwdriver bit) or directly a connector 90 such as a screw can be inserted. Fig. In the decoupled state of the uncoupler 45 shown in Figure 2, the workpiece-side part 40 is positioned away from the drive-side part 41 by means of the spring element 36 shown, so that a distance remains between the axle 42 and the axle receptacles 48 and the axle 42 does not engage the axle receptacles 48.

[0036] Referring to the Fig. Figure 3 shows an exploded view of the components of a driving screw stop tool 10. This clearly shows how the adjusting sleeve 14 acts on the adjusting nut 28, whereby the adjusting nut 28 can be moved along with the adjusting sleeve 14 in order to be adjusted axially along the driving axis 60 on the adjustment path 32 (thread path). By adjusting the adjusting element 28 along the driving axis 60, the relative position between the uncoupler 45 and the contact element 18 is adjusted. Thus, for example, if the drive-side part 39 of the uncoupler 45 is adjusted along the driving axis 60 in the direction of the workpiece 70, a connector 90 can also be driven further into the workpiece 70 because the axis 42 remains in the axis receptacle 48 for a longer time before the uncoupler 45 separates.By finely adjusting the drive side 39 by means of the adjusting element 28, it is therefore possible to adjust how strongly the screw head 92 is pressed against the workpiece 70 when the connector 90 is driven into the workpiece 70.

[0037] With Fig. 3, the axis 42 is shown aligned with the axis holder 48, so that it can be seen that when the drive-side part 39 is placed against the workpiece-side part 40 of the uncoupler 45, the axis 42 engages in the axis holder 48 and thus the coupled state is assumed, wherein the spreading force of the spring element 36 may have to be overcome in order to couple the parts 39, 40 into one another.

[0038] Furthermore, Fig. 3 clearly shows the interlocking of the adjustment sleeve 14 and the screw stop sleeve 12, with the counter-drivers 46 of the adjustment sleeve 14 engaging between the drivers 44 of the screw stop sleeve 12. During a rotational movement of the drive 30, during which the screw stop sleeve 12 arranged on the drive 30 also rotates, the adjustment sleeve 14 will therefore also rotate when the depth adjustment 8 is in the closed state. The drivers 44 and counter-drivers 46 can be toothed, or they can also be retaining lugs. By adjusting the adjustment sleeve 14 along the drive axis 60, i.e. moving it away from the screw stop sleeve 12, the toothing of the drivers 44 and counter-drivers 46 is released, so that the adjustment sleeve 14 can be freely rotated against the screw stop sleeve 12.

[0039] With Fig. Figure 4 shows a further embodiment of the driving screw stop tool 10, which additionally has a tamper-evident device 50. The tamper-evident device 50 prevents movement of the adjustment sleeve 14 in the direction of the driving axis 60. Thus, the adjustment sleeve 14 is securely held in the closed position, and accidental actuation of the depth adjustment 8 is reliably excluded.

[0040] Referring to the Fig. 5 shows the embodiment with tamper protection 50 in a perspective view, wherein it can be seen that the tool holder 38 is slightly recessed behind the protective element 24, so that when the driving-screw stop tool 10 is placed against a workpiece 70 and a compressive force is applied to the driving-screw stop tool 10 via the driving device 80, the tool holder 38 is displaced relative to the protective element 24 or the contact element 18 in the direction of the driving axis 60 or the workpiece 70. As soon as the contact element 18 (or, if inserted, the protective element 24) is placed against the workpiece 70, the drive 30, which is held rigidly relative to the contact element 18 by means of the adjustment element 28 and the contact element 18 adjoining it, can no longer be adjusted towards the workpiece 70.Now it happens that the workpiece-side part 40 of the uncoupler 45 continues to engage the workpiece 70 when the driving tool 80 continues to be operated, and detaches from the drive-side part 39 when the connector 90 is driven in.

[0041] With Fig.6 shows the driving screw stop tool 10 in an operating position arranged on a driving tool 80, wherein a connector 90, which has a sealing washer 94, is inserted with its connector head 92 into the tool holder 38 and is already partially driven into a workpiece 70. In the position shown, the uncoupler 45 is uncoupled. This occurs when no more force is exerted on the driving screw stop tool 10 in the direction of the driving axis 60, after which the spring element 36 separates the two parts 39, 40 of the uncoupler 45. As soon as the driving tool drive 82 of the driving tool 80 imparts a rotational movement to the driving screw stop tool 10, only the drive-side part 39 of the uncoupler 45 rotates, but not the workpiece-side part 40.When a force is applied in the direction of the drive axis 60, the uncoupler 45 is engaged, and the rotational movement is also transmitted to the workpiece-side part 40, causing the tool holder 38 and the connector 90 arranged in the tool holder 38 to rotate. The connector 90 is driven further into the workpiece 70 until the contact element 18 comes into contact with the workpiece 70. Further adjustment of the drive part 39 of the uncoupler 45 along the drive axis 60 in the direction of the workpiece 70 is then no longer possible, as the contact element 18 prevents this. However, the workpiece-side part 40, with the connector 90, will continue to move just farther toward the workpiece 70 until the uncoupler 45 is disengaged. The set position of the adjustment element 28 defines the screw stop condition or the screw-in depth of the connector 90.

[0042] It will be apparent to those skilled in the art that the embodiments described above are to be understood as examples and that the invention is not limited to them, but can be varied in many ways without departing from the scope of the claims. Furthermore, it is apparent that the features, regardless of whether they are disclosed in the description, the claims, the figures or otherwise, also individually define essential components of the invention, even if they are described together with other features. In all figures, the same reference numerals represent the same objects, so that descriptions of objects that may only be mentioned in one or at least not with regard to all figures can also be transferred to these figures and exemplary embodiments with regard to which the object is not explicitly described in the description.
