Description

The present invention relates to a nail device according to the preamble of claim 1.

Nailers are used in particular in construction to nails or staples in an object or substrate, for. B. of wood, concrete or steel to bring. As a result, a larger number of nails or staples can be introduced into the article or substrate in a shorter time than with a manual hammering of nails into the article. The nail devices are generally driven pneumatically, electrically or by combustion technology. A nail magazine is used to store a larger number of nails or staples.

The DE 195 08 437 C2 shows a pneumatically operated nail device and from the DE 89 07 788 U1 is an electrically operated nail device known. The DE 31 516 58 A1 describes a gas-powered setting tool. From the US Pat. No. 6,948,647 B1 is a fastening tool with a slip-resistant handle known. In the US 2002/0100787 A1 a power operated stapler is described. By the US 5 054 678 a furniture clamp tool has become known. The US 6,161,744 describes a support for a fastening tool and in the US 5,267,682 An adjustment mechanism for a support leg of a fastening device is described.

From the WO 96/39286 a nail device is known in which a spacer element is adjustably mounted on a clip. The spacer element has a plurality of projections, which together with a device nose of the nailer form a multipoint bearing.

The nails should be driven as perpendicular as possible to a fictitious object plane spanned by the surface of the article or substrate into the article or substrate with the nail device. The nail device is placed for introducing the nails with a pin guide element on the object and also it is known that a support foot is formed on the nail device. The support foot in this case has only one support element, so that together with the pin guide element, the nail device can be placed on the object or surface by means of a two-point bearing. As a result, it is possible that disadvantageously the nail device during the setting of the nails is tilted laterally, so that the nails are set at an angle. However, skewed nails have the disadvantage that here it comes to significant failures or to a reduced attachment by means of the set nails.

The object of the present invention is therefore to provide a nail device in which the nails without a particular alignment of the nailer by the operator substantially perpendicular to a fictitious object plane spanned by the surface of the article in which the nails are driven can be driven into the object.

This object is achieved with a nail device comprising a housing, in particular a nail magazine, a setting mechanism for setting the nails, a pin guide element for resting on the object in which the nail are to be introduced, so that the pin guide element for setting the nails and support for the nail device is a trigger for activating the setting mechanism, a support foot for additional support of the nail device, wherein the support leg with two Supporting elements is provided for a two-point bearing, so that the nail device has a three-point bearing together with the pin guide element. The support leg is mounted pivotably about a pivot axis on the other nail device, so that in a first pivot position of the support leg, the two support elements have a distance to a fictitious device level and in a second pivot position, the two support elements of the fictitious device level are essentially cut and a longitudinal axis the bolt guide element and pivot axis lie in the fictitious device level. In the first pivot position, the nail device thus has a three-point bearing and in the second pivot position are the two point bearings on the support leg in the fictitious device level, so that thereby the nail device when resting the support leg and the pin guide element on the object or surface tilted or swiveled is. In certain applications of the nailer, it may be necessary that a tilting of the nailer when lying on the object is required, for example, to introduce nails obliquely into the ground or certain disabilities in the processing room of the nailer.

The support foot preferably protrudes from the housing or optionally from the nail magazine. In preferred variants, the support leg protrudes from a fuel container receptacle, such as e.g. a gas can compartment, a battery holder or a handle or a handle extension.

The nail device is provided with a support leg with two support elements, so that thereby the nail device has a three-point bearing. The bolt guide element forms the first point bearing and the two support elements on the support foot form the two second and third point bearings for the nail device. In the case of an article having a substantially planar surface, so that a fictitious object plane is spanned by the article or substrate in which the nails are to be driven by the nail device, the bolt guide element, ie a longitudinal axis of the article, can thus be fastened by means of the three-point bearing Bolt guide element, are aligned substantially perpendicular to the object plane, since due to the three-point bearing of the nailer, the longitudinal axis of the pin guide element is aligned substantially perpendicular to the fictitious object plane. The geometry of the two support elements is thus designed so that when, resting on a flat surface or the object plane at a resting both support elements and the pin guide element on the object plane, the longitudinal axis is aligned perpendicular to the object plane.

In particular, the two support elements which form the two-point support on the support foot, a distance of at least 1 cm, 3 cm, 5 cm or 10 cm to each other and / or the end of the pin guide element and the ends of the two support elements form the corners of a fictitious triangle and the sides of the fictitious triangle are at least 1 cm, 3 cm, 5 cm or 10 cm apart and the height of the fictitious triangle is at least 1 cm, 3 cm, 5 cm or 10 cm. The two support elements require a corresponding distance, so that a sufficient three-point bearing of the nailer is guaranteed, d. H. tilting of the nail device is substantially hindered in practice.

In a further embodiment, the two support elements at a distance of at least 5 cm, 10 cm, 20 cm or 30 cm to the pin guide element.

Preferably, the pin guide element serves to guide the nails or staples when setting or introduction into the article.

Suitably, the two support members are separate components, so that the two support elements form separate support feet, ie the Sützfuß is in two parts.

Preferably, in the first pivot position, the distance of the two Stützeleinente to the fictitious device level substantially the distance between the two support members to the pivot axis, in particular, the distance between the two support elements in the first pivot position to the fictitious device level is at least 0.5 cm, 1.5 cm, 2.5 cm or 5 cm and / or the first and second pivot position are pivoted substantially at 90 ° to each other about the pivot axis. The first and second pivot positions are pivoted substantially at 90 ° to each other, ie with a deviation of less than 10 °, 5 °, 3 ° or 2 °, as 90 ° or right angle pivoted to each other. In the first pivoting position, the distance between the two support elements or the ends of the support elements to the fictitious plane substantially corresponds to the distance of the two support elements or the ends of the support elements to the pivot axis, ie with a deviation of less than 2 cm, 1 cm, 0.5 cm or 0.2 cm.

Preferably, the two support elements have the same distance from the pivot axis. In an alternative embodiment, the two support elements have different distances to the pivot axis.

In a variant, the pivot axis is aligned substantially parallel to the longitudinal axis of the pin guide element or is at an acute angle, in particular between 3 ° and 45 °, preferably between 5 ° and 30 °, for example between 7 ° and 20 °, to the longitudinal axis of Bolt guide element aligned and / or the pivot axis is in the fictitious device level. The pivot axis is aligned substantially parallel to the longitudinal axis of the pin guide element, d. H. with a deviation of less than 5 °, 3 °, 2 ° or 1 ° aligned with the longitudinal axis of the pin guide element.

Suitably, the support leg is attached and mounted with a pivoting mechanism on the other nail device and is fixed to the pivot mechanism in the first and second pivot position and detachable, in particular latched and unlatched, in particular by means of a movement of the support leg parallel to the pivot axis. When applying a force or movement on the support foot substantially parallel to the pivot axis of the support leg of this can be attached to the other nail device in the-two pivot positions and released, ie in particular latched and unlatched. This ensures a particularly simple fixation of the support leg in the two pivot positions.

In an additional embodiment, the support leg is removable from the remainder of the nail device. With a removed support leg, the nail device has only a one-point storage, d. H. only the pin guide element serves for bearing on the ground. As a result, the nails can be introduced at any angle to the fictitious object plane into the object or ground.

Preferably, the support leg is releasably secured to the other nail device and can be brought from a first to a second pivot position by complete release of the remaining nail device.

In a further embodiment, the support leg is attached to the rest of the nailing device with an overload mechanism such that upon application of force to the support leg exceeding an overload force, the support leg is automatically releasable from the remainder of the nailing device, in particular the overload mechanism is formed by the pivoting mechanism , In the practice of the nail device this can also fall, for example, and the support foot strikes the object. The overload mechanism ensures that when an overload force is exceeded with the overload mechanism, the connection between the support leg and the rest of the nail device is automatically and automatically released, thereby reducing the risk of damage to the support foot or the device.

In particular, the two support elements, in particular in the end region of the support elements, at least partially, in particular completely, made of rubber. The contact areas of the rubber support elements ensure a particularly secure hold of the nail device, in particular against slippage on the surface of the object.

In a further embodiment, the setting mechanism is electrical, pneumatic or combustion technology, wherein the fuel in particular solid, liquid or gaseous, operable and / or the setting mechanism and the support leg are connected to each other via a nail magazine.

Suitably, the nail device comprises a battery in an electrically operated setting mechanism.

In a pneumatically operated setting mechanism, the nail device preferably comprises a pneumatic interface for connecting a compressed air hose.

Preferably, the nail device in a combustion-driven setting mechanism comprises a fuel cartridge, in particular in the form of a cartridge strip or a gas can.

In an additional embodiment, the housing of the nail device consists at least partially, in particular completely, of metal and / or plastic.

In an additional embodiment, the nail device has a separate actuator in addition to the trigger for disabling the setting mechanism. When the setting mechanism is activated, the nailing device drives the nails into the object, and when the setting mechanism is deactivated, the setting mechanism is inoperative, i. H. no nails are driven into the article by the nailer.

Suitably, the nailer is also considered as a stapler, d. H. with the nail device and brackets or other setting elements can be introduced into the article.

In a further embodiment are in the second pivot position of the support leg, the end of only one support element and the end of the bolt guide element in a fictitious object plane, as a sharper Angle between the pivot axis of the support leg and the longitudinal axis of the pin guide element is present.

Nailers 1 serve nails, not shown in an object 16 or surface 16, z. B. of wood, concrete or steel, collect. The nail device 1 has for this purpose a housing 2 made of metal and / or plastic, which is generally in several parts. In this case, a non-illustrated setting mechanism, which is operated electrically, pneumatically or combustion technology, is disposed within a housing body 3 enclosed by the housing 2. From another part of the housing 2, a nail magazine 5 is enclosed. The nail magazine 5 comprises a large number of nails, and for setting the nails, the nails are conveyed from the nail magazine 5 to the setting mechanism and electrically or by means of the setting mechanism by a pin guide member 6 as part of the setting mechanism in the article 16 pneumatically driven. The pin guide element 6 has a longitudinal axis 12, and the setting mechanism can be activated with a trigger 7. To hold the nail device 1, the housing 2 is designed to the effect that this also forms a handle 4 for holding the nail device 1.

In Fig. 1 a known from the prior art nail device 1 is shown. The nails are driven by the bolt guide element 6 in the direction of the longitudinal axis 12 of the pin guide element 6 in the substrate or object 16. The nails should thereby be driven as perpendicular as possible to a fictitious object plane 17 spanned by the object 16 or the surface of the object 16. For this purpose, the nail device 1 on a support foot 8 and the support leg 8 has in the illustration in Fig. 1 from the prior art, only one support element, so that thereby the nail device 1 of the prior art only has a two-point bearing. The nail device 1 can thereby about a tilt axis, which due to the formation of cut in Fig. 1 the object plane 17 shown in dashed lines corresponds, since the object plane 17 due to the sectional formation in Fig. 1 perpendicular to the plane of Fig. 1 cut 1. When tilting the nailer 1, the nails are thereby obliquely to the fictitious object plane 17, z. B. driven at an acute angle in the article 16. This is associated with disadvantages, for example, by setting failures or a lower attachment of the nails.

In the Fig. 2 to 5 Two embodiments of a nail device 1 according to the invention are shown. In Fig. 2 In this case, a first embodiment of the nail device 1 according to the invention is shown. The support leg 8 has a first support element 9 and a second support element 10. The end regions 11 of the two support elements 9, 10 thereby form a second and a third point as a point bearing for the nail device 1, so that together with the point bearing on the pin guide element 6, the nail device 1 according to the invention has a three-point bearing.

The support leg 8 is pivotable about a pivot axis 13 and the pivot axis 13 is aligned parallel to the longitudinal axis 12 of the pin guide element 6. In Fig. 4 is a second pivot position and in Fig. 5 a first pivotal position of the support leg 8 is shown. In the swivel position in Fig. 5 have the two end portions 11 a distance of about 3 cm to a fictitious device level 14 and also a distance due to the structural or geometric design of the support leg 8 to the pivot axis 13 of the support leg 8. The fictitious device level 14 lies in the longitudinal axis 12 and in the pivot axis 13. In this in Fig. 5 shown first pivot position of the support leg 8 can not be tilted due to the three-point bearing of the nailer nailer 1 when introducing the nails, so that thereby a substantially vertical insertion of the nails is ensured to the fictitious object plane 17. In the in Fig. 4 shown second pivot position of the support leg 8 is substantially 90 ° about the pivot axis 13 with respect to the first pivot position according to Fig. 5 pivoted. In this in Fig. 4 shown pivot position cut the two end portions 11 of the support member 9, 10, the fictitious device level 14 and have a very small distance of z. B. less than 1 cm to the fictitious device level 14 on. In this pivotal position of the support leg 8 can be tilted while resting on the object 16 as in the prior art, the nail device 1. In certain applications with the nailer 1, z. B. for controlled oblique introduction of nails or when working in a confined workspace, z. B. in a corner, this may be necessary or desirable in exceptional cases.

In Fig. 3 a second embodiment of the nail device 1 according to the invention is shown. In the following, only the differences from the first embodiment of the nail device 1 according to the invention will be explained in detail Fig. 2 described. The pivot axis 13 is aligned at an acute angle of about 10 ° to the longitudinal axis 13 and lies in the fictitious device level 14. An auxiliary longitudinal axis 15 is displaced parallel and thus corresponds in its orientation of the longitudinal axis 12. The auxiliary longitudinal axis 15 is thus a parallel shifted longitudinal axis 12. In the in Fig. 3 Thus, shown only second pivotal position of the support leg 8 is only the first support member 9 on the article 16 and the second support member 10 has no contact with the article 16. Upon pivoting of the support leg 8 in the first pivot position, however, are again the two support elements 9, 10 and the pin guide member 6 on the article 16, so that in an analogous manner as in the first embodiment of the nail device according to the invention Fig. 2 again a three-point storage is guaranteed with the nailer 1.

Overall, significant advantages are associated with the nail device 1 according to the invention. The nail device 1 has a three-point bearing, so that thereby an exact placement of the nails perpendicular to the fictitious object plane 17 is possible. In order to ensure in certain applications of the nail device 1, a tilting of the nail device 1 as in a two-point storage, due to the second pivot position of the support leg 8, the nail device 1 can also be tilted in the application for setting the nails. Furthermore, the support leg 8 and the other nail device 1, ie the nail magazine 5 in the embodiment according to Fig. 2 and 3 , be removed, since a corresponding unillustrated pivoting and / or mounting mechanism for the support leg 8 is formed accordingly. Without the support leg 8, the nails 1 can be driven into the object 16 at any acute angle with respect to the fictitious object plane 17. In certain applications of the nail device 1, this is also required and desired.
