Description

[0001] The invention relates to a screwing tool for handling screws, wherein the screwing tool has a torque transmission profile which is designed to be inserted into a torque absorption profile of a screw.

[0002] Such screwing tools for handling screws, wherein the screwing tool has a torque transmission profile which is designed to be inserted into a torque absorption profile of a screw, serve to tighten or loosen a screw by applying a torque.

[0003] Conventional screwdriving tools each have a single torque transmission profile that can be used to handle a specific screw size. If a different screw size with a different diameter is to be handled, a different screwdriving tool is required for that screw size.

[0004] Changing the corresponding screwing tools is perceived by users, for example craftsmen, as annoying and time-consuming, for example when different screw sizes have to be handled with different bit inserts and this requires exchanging different bit inserts.

[0005] The present invention is based on the object of providing a screwing tool which is improved with regard to the aforementioned disadvantages.

[0006] This object is achieved according to the invention in that the screwing tool is provided with at least one further torque transmission profile which is arranged adjacent and adjacent to the torque transmission profile.

[0007] The screwing tool according to the invention thus comprises at least two different torque transmission profiles arranged adjacent to and adjacent to each other. Such a screwing tool can easily handle different screw sizes that differ in diameter. Switching between different screwing tools is thus no longer necessary.

[0008] According to an advantageous embodiment of the invention, the additional torque transmission profile is arranged, in particular rigidly, on an end face of the torque transmission profile. The torque transmission profile and the additional torque transmission profile are thus arranged directly adjacent to one another in the axial longitudinal direction of the screwing tool, so that the additional torque transmission profile forms an axial extension on the end face of the torque transmission profile. The torque transmission profile and the additional torque transmission profile are, in particular, formed integrally, i.e., as a single component.

[0009] According to an advantageous embodiment of the invention, the additional torque transmission profile has an outer diameter that is smaller than the outer diameter of the torque transmission profile. This allows the screwing tool with the torque transmission profiles to be easily inserted into corresponding torque absorption profiles of screws of different screw sizes, so that different screw sizes that differ in diameter can be easily tightened and loosened with the screwing tool according to the invention.

[0010] According to an advantageous embodiment of the invention, the torque transmission profile and the further torque transmission profile are each designed, in particular, as a hexagonal profile. Such a hexagonal profile can be easily inserted into a corresponding torque-absorbing profile of a screw.

[0011] According to an advantageous embodiment of the invention, the torque transmission profile and the additional torque transmission profile are each designed as a Torx profile. A Torx profile is a screw driving profile designed as an external hexalobular drive, which is suitable for handling Torx screws that have a hexagon socket as the torque absorption profile. Such Torx screws and corresponding Torx screwing tools have become particularly popular in the trades, as the screw and the screwing tool are less susceptible to damage compared to other systems, such as Phillips screws and Phillips screwing tools.

[0012] According to an advantageous embodiment of the invention, the torque transmission profile is designed as a Torx profile T40 or TX40 or TH40.

[0013] According to an advantageous embodiment of the invention, the further torque transmission profile is designed as a Torx profile T25 or TX25 or TH25.

[0014] According to an advantageous embodiment of the invention, the further torque transmission profile is designed as a Torx profile T15 or TX15 or TH15.

[0015] With the screwing tool according to the invention, two different Torx screws with torque profiles T40 and T25 or T40 and T15 can be handled without having to change the screwing tool. These screw sizes have become established as standard screw sizes, particularly in the skilled trades, for example, in carpentry.

[0016] According to an advantageous embodiment of the invention, the screwing tool is designed as a screwdriver. The torque transmission profile and the additional torque transmission profile are arranged, in particular, on a front side of a screwdriver shaft opposite a handle.

[0017] According to an advantageous and alternative embodiment of the invention, the screwing tool is designed as a bit insert. A bit insert has a bit receptacle, for example, an external hexagon profile, which can be inserted into a corresponding receptacle of a bit holder. The torque transmission profile and the additional torque transmission profile are arranged in particular on a front side of the bit insert opposite the bit receptacle.

[0018] Further advantages and details of the invention are explained in more detail with reference to the embodiment shown in the schematic figure.

[0019] The figure shows a screwing tool 1 according to the invention for handling screws.

[0020] In the illustrated embodiment, the screwing tool 1 is designed as a bit insert 2, which has a shaft-shaped bit receptacle 3 designed as an external hexagon profile, with which the bit insert 3 can be inserted into a receiving recess of a bit holder 4.

[0021] The screwing tool 1 has a torque transmission profile 5 designed to be inserted into a torque absorption profile of a screw (not shown in detail), which is formed in a screw head of the screw. The torque transmission profile 5 of the screwing tool 1 and the torque absorption profile of the screw have a complementary interacting shape, so that a torque can be transmitted between the torque transmission profile 5 of the screwing tool 1 and the torque absorption profile of the screw, with which the screw can be tightened or loosened.

[0022] The screwing tool 1 according to the invention is provided with at least one further torque transmission profile 6, which is arranged adjacent and adjacent to the torque transmission profile 5. In the illustrated embodiment, the further torque transmission profile 6 is arranged or formed on an end face 5a of the torque transmission profile 5. Preferably, the further torque transmission profile 6 is formed or formed integrally on the end face 5a of the torque transmission profile 5 in one piece and is thus fixed and rigid. The torque transmission profile 5 and the further torque transmission profile 6 are thus formed integrally.

[0023] The bit insert 2, which consists of the shaft-shaped bit holder 3, the torque transmission profile 5 and the further torque transmission profile 6, is preferably designed as a one-piece component.

[0024] The torque transmission profile 5 has an outer diameter D. The further torque transmission profile 6 has an outer diameter d which is smaller than the outer diameter D of the torque transmission profile 5.

[0025] The torque transmission profile 5 and the further torque transmission profile 6 are each designed as a hexagonal profile.

[0026] In the illustrated embodiment, the torque transmission profile 5 and the further torque transmission profile 6 are each designed as a Torx profile.

[0027] In particular, the torque transmission profile 5 is designed as a Torx profile T40 or TX40 or TH40, with which Torx screws of size T40 can be handled.

[0028] In particular, the further torque transmission profile 6 is designed as a Torx profile T25 or TX25 or TH25, with which Torx screws of size T25 can be handled.

[0029] In particular, the further torque transmission profile 6 is designed as a Torx profile T15 or TX15 or TH15, with which Torx screws of size T15 can be handled.

[0030] Thus, if the torque transmission profile 5 of the screwing tool 1 according to the invention is designed as a Torx profile T40 or TX40 or TH40 and the further torque transmission profile 6 is designed as a Torx profile T25 or TX25 or TH25, Torx screws of size T40 and Torx screws of size T25 can be handled with the screwing tool 1 according to the invention without requiring a change of the screwing tool 1. The axial length of the further torque transmission profile 6 is preferably designed such that the screwing tool 1 can be inserted into a torque absorption profile of a Torx screw of size T40 such that the torque transmission profile 5 interacts with the torque absorption profile of the Torx screws of size T40.

[0031] Thus, if the torque transmission profile 5 in the screwing tool 1 according to the invention is designed as a Torx profile T40 or TX40 or TH40 and the further torque transmission profile 6 is designed as a Torx profile T15 or TX15 or TH15, Torx screws of size T40 and Torx screws of size T15 can be handled with the screwing tool 1 according to the invention without requiring a change of the screwing tool 1. The axial length of the further torque transmission profile 6 is preferably designed such that the screwing tool 1 can be inserted into a torque absorption profile of a Torx screw of size T40 such that the torque transmission profile 5 interacts with the torque absorption profile of the Torx screws of size T40.

[0032] The invention is not limited to the illustrated embodiment, in which the screwing tool 1 has two torque transmission profiles 5 and 6. It is understood that the screwing tool 1 can, for example, have three torque transmission profiles, wherein an additional, third torque transmission profile is formed or molded integrally and thus firmly and rigidly on the end face 6a of the further torque transmission profile 6, the outer diameter of which is smaller than the outer diameter d of the further torque transmission profile 6. Thus, a screwing tool 1 can be created whose three torque transmission profiles 5 are designed, for example, as Torx profiles T40, T25 and T15, so that Torx screws of size T40, Torx screws of size T25 and Torx screws of size T15 can be handled with the screwing tool 1 according to the invention without requiring a change of the screwing tool 1.

[0033] Furthermore, the invention is not limited to the aforementioned Torx profiles T40, T25, and T15. It is understood that the torque transmission profile 5 and the additional torque transmission profile 6 may also have other Torx profiles, in which the Torx profile of the additional torque transmission profile 6 has a smaller outer diameter than the Torx profile of the torque transmission profile 5.

[0034] Furthermore, the invention is not limited to the design of the torque transmission profile 5 and the additional torque transmission profile 6 to two differently sized Torx profiles. Alternatively, the torque transmission profile 5 and the additional torque transmission profile 6, which is integrally connected to the torque transmission profile 5, can each be designed as a hexagonal profile, for example, an external hexagon profile, for various screws with internal hexagon profiles as a torque absorption profile. Alternatively, the torque transmission profile 5 and the additional torque transmission profile 6, which is integrally connected to the torque transmission profile 5, can each be formed from profiles commonly used on the market, for example, Robertson profiles, Triple Square profiles, Torq profiles, or Tri-Wing profiles.
