[0031] FIG. 1 is a perspective view of an exemplary cover assembly according to one embodiment.

[0032] FIG. 2 is a perspective view of an exemplary cover assembly according to one embodiment.

[0033] FIG. 3 is a perspective view of an exemplary retaining element according to one embodiment.

[0034] All figures are schematic, not necessarily to scale and generally only show parts which are necessary in order to elucidate the invention, wherein other parts may be omitted or merely suggested.

DETAILED DESCRIPTION OF THE INVENTION

[0035] An exemplary insulating tool cover assembly (1) is shown in FIG. 1, arranged on a power tool PT (in the illustrated case a handheld angled tightening tool) to thereby provide electrical insulation by covering a front portion PT1 of the tool PT.

[0036] The cover assembly comprises a first cover portion 10 and a second cover portion 20 which as may be seen form FIG. 1 each from approximately one half of an assembled cover structure and together cover the front portion PT1 of the power tool, and a releasable retaining element 30 arranged at the front end 10a,20a of the cover assembly in order to hold the first and second cover portion 10, 20 together. In the illustrated embodiment, the first and second cover portion 10, 20 extend over approximately ⅔ of the axial length of the power tool and thus cover approximately ⅔ of the surface area of the tool PT. The remaining part of the power tool PT not covered is mainly the handle of the tool, which is in itself covered in rubber, i.e. it is non-conductive as such.

[0037] The first and second cover portion 10, 20 as well as the retaining element 30 are in order to provide the insulation needed made of a plastic material. Moreover, not visible in the black and white FIG. 1, the first and second cover portion 10, 20 have a bright color different from that of the power tool in order to visually convey to a user that the tool is provided with insulation.

[0038] The retaining element 30 is in the illustrated embodiment ring shaped, i.e. substantially cylindrical, and arranged at a first substantially circular end opening 40 of the assembled cover. A first portion 31 of the retaining element, in this case a cylindrical first portion comprising a thread is arranged in the opening 40. The retaining element 30 further comprises a second axially extending portion 32 adapted to, in use, partly cover a socket (not shown) attached at the front end PT1 of to the tool.

[0039] A second retaining structure 50 in the form of a resilient ring 50 is arranged at a suitable distance from a rear end of the cover 10b, 20b to hold the first and second cover portion together at this rear end.

[0040] A second exemplary embodiment of the insulating tool cover assembly (1) is shown in FIG. 2. As for the embodiment shown in FIG. 1, the cover assembly comprises a first cover portion 10 and a second cover portion made from an insulating plastic material 20 which together cover the front portion PT1 of the power tool, and a releasable retaining element 30 arranged at the front end 10a, 20a of the cover assembly. However, the embodiment of FIG. 2 is shorter compared to the first embodiment and the first and second cover portion 10, 20 extend over approximately ⅓ of the axial length of the power tool.

[0041] A first retaining element 30 according to one embodiment is shown in greater detail in FIG. 3. The illustrated retaining element 30 comprises a cylindrical surface portion 31 comprising a thread 32 adapted to cooperate with a corresponding thread on a cylindrical surface portion 40 formed by a first surface portion 40a comprised by the first cover portion 10 and a second surface portion 40b comprised by the second cover portion 20 together forming a first substantially circular end opening 40 of the assembled cover. The retaining element 30 further comprises a second axially extending portion 33 adapted to, in use, as mentioned above partly cover a socket.

[0042] In order to provide the electrical insulation, the user arranges the first and second cover portions to cover the front part of the tool followed by applying the first retaining element at the front end of the tool and the second rear retaining clamp 60 at the rear end of the cover in order to hold the cover portions firmly together. Preferably, the user is provided with not only one first retaining element 30 but a kit comprising a number of such elements 30 differing in size and design, such that, based on in the illustrated embodiment the choice of socket to be attached at the tool, a suitable retaining element 30 ensuring sufficient insulation may be chosen and applied by the user.

[0043] While the invention has been illustrated and described in detail in the drawings and foregoing description, such illustration and description are to be considered illustrative or exemplary and not restrictive; the invention is not limited to the disclosed embodiment. The skilled person understands that many modifications, variations, and alterations are conceivable within the scope as defined in the appended claims. Additionally, variations to the disclosed embodiments can be understood and effected by those skilled in the art in practicing the claimed invention, form a study of the drawings, the disclosure, and the appended claims.
