Description

Technical Field

[0001] The present invention relates to a hand tool having a working area and a gripping area, wherein the gripping area is arranged in a gripping sleeve, wherein the gripping sleeve has an end corresponding to the working area and an opposite free end, and may be provided with a functional component, wherein the gripping sleeve also has through holes extending longitudinally along the gripping sleeve and forming a first and a second opening with a free opening cross section even in the unused state, the functional component being inserted into the through holes to be held on the gripping sleeve.

[0002] The present invention also relates to a functional component for locking connection with the grip area of ​​a hand tool, wherein the functional component has an engaging section for engaging in a retaining recess in the grip area and a functional section. Prior Technology

[0003] Hand tools of this type are known, for example, in the form of pliers, such as combination pliers, side-cutting pliers, or pump pliers, or in the form of scissors, such as household scissors or garden scissors. The gripping area is provided with a grip sleeve. In this case, it is usually a plastic grip sleeve that can be manufactured using a plastic injection molding process. In this regard, grip sleeves that are manufactured separately, particularly injection molded, and thus fitted onto the gripping area are known. In this regard, several solutions are also known in which the gripping area is directly extruded and encapsulated. Furthermore, grip sleeves manufactured using a two-component injection molding process are known, which accordingly have a soft plastic area and a hard plastic area for easy gripping.

[0004] Possible arrangements of functional components on the grip sleeve are also known. These functional components may be adapted to support or impede the function of the hand tool, for example, in the form of spring elements or sealing plates. Such functional components may also have functions completely independent of the hand tool equipped with the grip sleeve that carries them, for example, when the functional component is constructed as an LED light or, further for example, as a non-contact voltage tester.

[0005] Regarding pliers, see also the prior art, including EP 528252 A1 (US 5845551 A), EP 0421107 A2, DE 3929323 C2, WO 2021 / 160598 A1, DE 102020103467 A1, DE 102018123705, WO 2019 / 207054 A1 (US 2021 / 0167586 A1) and WO 2018 / 146191 A1 (US 2020 / 0009750 A1).

[0006] A hand tool having a grip sleeve and a functional component disposed on the grip sleeve is known from DE 10 2017 101 197 A1. This functional component, in particular, has a deflectable wire clip, for example, for hanging the hand tool. For this purpose, the functional component is bonded or welded to the grip sleeve.

[0007] US 7,468,674 B2 discloses a hand tool with a grip sheath, wherein a mounting component is provided to be fitted onto the grip sheath, having correspondingly two openings: one for gripping the sheath and another for a functional component. US 2014 / 0013544 A1 discloses a hand tool in which a ring component surrounds the metal gripping area, and a second ring component is held within this ring component to secure a functional component.

[0008] A hand tool is known from EP 2 489 480 A2, wherein a through hole is constructed in one of the gripping sheaths, in which a spring component is accommodated. The first opening has an opening section facing the opposite gripping sheath of the pliers-like tool, and is constructed as a free end away from the gripping area, approximately at half the length of the gripping area. Summary of the Invention

[0009] Based on the aforementioned prior art, the object of the present invention is to advantageously design a hand tool of the type in terms of accommodating the functional components in a grip sleeve, and also to provide a hand tool having such functional components and to provide a functional component of the type of said type designed in an advantageous manner.

[0010] According to the first inventive concept, the solution to achieve this objective is a hand tool in which the following arrangement is adopted: its first and second openings are substantially rectangular in terms of cross-section relative to the through-hole direction, and the first opening corresponding to the free end is opposite to the second opening in the insertion direction of its functional component.

[0011] Regarding its functional components, one feasible solution to achieve this objective is provided, specifically in that its engaging section is constructed as a planar region that is adapted to a through hole having a substantially rectangular opening cross-section.

[0012] The rectangular cross-section of the through-hole not only allows for the pre-orientation of the functional component to be inserted, but also provides anti-torsion protection for the component during insertion. This solution is particularly effective when the functional component has a planar area that matches the cross-section of the through-hole.

[0013] The width of the through hole, preferably, is approximately 4 to 8 times the height of the through hole or the height of the planar area of ​​the functional component when viewed transversely in the cross section, and more specifically, approximately 5 to 7 times or approximately 6 times.

[0014] A through-hole, located on or within the grip sleeve in the region of the free end, forming a retaining area, advantageously provides a solution for selectively arranging functional components on the grip sleeve. Therefore, a grip sleeve with such a through-hole can be equipped with different functional components, and more preferably, the insertion and retention of the functional component in the through-hole can be selected so that the functional component can be replaced even if the insertion and retention is eliminated when necessary.

[0015] This hand tool can first and foremost be a hand tool with only a single gripping area. This point is, for example, related to a knife or screwdriver.

[0016] However, this hand tool can also be constructed with two tool parts arranged intersecting each other in the joint area, wherein each tool part forms a working area on one side of the joint area and a gripping area on the other side. In this case, each gripping area can be arranged in a first or second gripping sheath. Such hand tools are typically pliers or scissors.

[0017] For a hand tool having two gripping areas and corresponding two gripping sleeves, depending on the circumstances, only one of the two gripping sleeves may be provided with the through-hole described above for inserting and holding a functional component. In this case, for identical components that can be manufactured for the gripping sleeves, both gripping sleeves are preferably provided with such a through-hole, so that both gripping sleeves can be fitted with functional components, and different functional components can be fitted as appropriate. When the through-hole of one of the gripping sleeves holds a functional component, the through-hole of the other gripping sleeve may also remain unused, or only a component with a closed through-hole may be inserted.

[0018] Further preferably, the functional component cannot be inserted directly or alone into the through hole. Specifically, the functional component preferably has a functional section that is also located outside the through hole in the inserted state, and an insertion section that is fully or mostly inserted into the through hole in the use state.

[0019] Other features of the invention will be described below, and illustrated in the accompanying drawings, generally through preferred combination with the subject matter of claim 1 and / or other independent claims or features of other claims. However, these features may also be combined with individual features of claim 1 and / or other independent claims or other claims, or may be the essence of the invention in themselves.

[0020] Therefore, according to one feasible further embodiment of the inventive subject matter, it can be proposed that the through-hole is constructed within the grip sleeve itself as an indivisible component of the grip sleeve, and depending on the case, is constructed within the first and / or second grip sleeve itself. Therefore, more preferably, the through-hole of the grip sleeve can be accordingly considered and formed during the manufacturing process of the grip sleeve, particularly during the plastic injection molding process.

[0021] Even more preferably, the through-hole is selected and arranged so that hand tools equipped with such a grip sleeve can be used safely even when the functional components are not inserted and held in the through-hole.

[0022] Further preferably, in a side view of the grip sleeve drawn along its entire length, the grip sleeve has a taper forming a free end. A first opening may be constructed in this taper or at least form a transition to this taper. This first opening is particularly, and preferably, visible in the view of the free end of the grip sleeve. The first opening is located within the outline of the grip sleeve given in this view.

[0023] In the case of a hand tool having two grip sleeves, namely a first and a second grip sleeve, the through-hole is preferably constructed on the side of the first and / or second grip sleeve facing the corresponding other grip sleeve. This refers to the preferred spatial arrangement of the tunnel-like through-hole within the grip sleeve itself. In a top view, where both grip sleeves are visible along their entire longitudinal extension, the through-hole is correspondingly arranged on the side of the grip area of ​​the other grip sleeve. For hand tools of this type, such as pliers or scissors, this is particularly advantageous in that the through-hole is preferably located in an area of ​​the grip sleeve that is not or not completely surrounded by the user's hand.

[0024] The through-hole is constructed in a continuous manner, having a first opening corresponding to the free end of the grip sleeve and a second opening pointing in the opposite direction. For inserting and retaining functional components, the through-hole is correspondingly formed in the region of the free end of the grip sleeve. Here, with a tunnel-like design between the first and second openings, the through-hole is open on both sides. Preferably, the through-hole's direction is substantially aligned with the extension direction of the gripping area of ​​the grip sleeve or hand tool during normal use, and its direction also corresponds to the insertion direction of the functional component. Further preferably, the opening sections of the first and second openings can be interconnected through an imaginary linear displacement in the insertion direction. This imaginary interconnection can be achieved by extending the opening wall of the non-through or through-hole into the region of a given corresponding section between the first and second openings. This extended region can be used, alone or supplementarily, to retain functional components within the through-hole.

[0025] According to a preferred technical solution, the length of the through hole viewed along the insertion direction can be several times the aforementioned height, for example, approximately 5 to 20 times the height, and for example, 8 to 12 times the height for typing.

[0026] According to a feasible technical solution, the opening surface that limits the height of the through hole can preferably transition steplessly to the adjacent surface section of the grip sleeve.

[0027] As previously mentioned, the through hole is preferably constructed in the area of ​​the gripping area facing opposite to the gripping area of ​​the gripping sleeve or the area of ​​the inner surface of the gripping sleeve facing opposite to the gripping sleeve of the hand tool, thereby substantially forming the inner and / or end-side positioning of the plug-in retaining functional component.

[0028] The through-hole may have a free cross-section, constrained by the opening wall, along its length. This free cross-section is equivalent to or larger than the opening cross-section of the first or second opening. A free cross-section equivalent to the opening cross-section of the first or second opening may be unconstrained along the length of the through-hole. In a linear projection along the length of the through-hole, the opening cross-section of the first opening may be completely contained within the opening cross-section of the second opening, or the channel cross-section of the second opening may be completely contained within the through-section of the first opening, without any region of the wall portion of the through-hole being inserted into the cross-section when viewed over the entire length. However, it may also be proposed that, as described above, a reduction in cross-section is preferably achieved at a particular location along the length of the through-hole, particularly through an extended region, for example, to retain a functional component within the through-hole in the inserted state. Conversely, the functional component, i.e., the section of the functional component within the through-hole in the inserted state, may also have a widened portion that causes elastic deformation of the unextended region of the segment or opening wall in the inserted state, thereby achieving or contributing to the desired retention.

[0029] The functional component may have an engaging section and a functional section for receiving within a through-hole. The engaging section is preferably also configured as a planar region adapted to the cross-section of the through-hole. The planar region may also preferably have a covering surface smaller than the opening cross-section of the through-hole within a portion of its longitudinal extension. In one feasible embodiment, the functional section may have a greater width and / or height extension compared to the engaging section or planar region.

[0030] According to a feasible technical solution, the engaging section can be constructed as an insertion section. Therefore, the insertion section of the functional component can be further inserted into the through hole from the first opening. A portion of the functional component preferably extends longitudinally from the free end of the gripping sleeve along the gripping sleeve.

[0031] In particular, considering the insertion direction originating from the free end of the grip sleeve, in the inserted state, the functional component can at least partially cover the end face of the free end of the grip sleeve. In the inserted position, this functional section can, depending on the situation, completely or partially form the end face of the free end of the grip sleeve. Therefore, in the inserted position, this functional section can, depending on the situation, be embedded in a correspondingly sized groove in the region of the free end of the grip sleeve.

[0032] Furthermore, this functional area may also have a label. This label is preferably constructed on the outside of the functional area. The label can be a direct representation of symbols or alphanumeric characters, or a carrier for such symbols or characters. The type of hand tool can be identified through further markings, such as icons or color codes, for example, by constructing and attaching functional components held on the grip. Additionally, this label may include a name or category name.

[0033] The marking surface can extend in a cross section at a right angle or an obtuse angle to the insertion section of the functional component, in which the insertion direction is shown as a line. In this regard, an angle of about 90 degrees to 150 degrees can be set, more preferably an obtuse angle of about 135 degrees, wherein such an obtuse angle can be further given particularly between the inner surfaces of the insertion section and the functional section facing away from the marking surface.

[0034] When the functional component is inserted, the marking surface is exposed to the outside. Correspondingly, when the functional component is inserted and held in place, a marking surface visible from the outside can be formed on the free end of the grip sleeve, so that the marking surface can indicate the type of hand tool, for example, even when the hand tool usually has a working area that is housed in a pocket or the like and is therefore not usually directly visible.

[0035] The insertion section can be formed as a single-piece side arm or a single-piece tongue-like structure. However, as an alternative, the insertion section can also have two side arms that are transverse to the insertion direction and spaced apart from each other by a certain distance. During insertion, both side arms of the insertion section pass through or engage with the through hole.

[0036] The insertion and retention of the functional component can be achieved by inserting an insertion section into the through hole, without the free end of the insertion section protruding from the opening opposite the insertion opening. Alternatively, the insertion section can be configured to fully protrude from the opposing opening, for example, to achieve locking retention in the area at the edge of the through hole opening.

[0037] Further preferably, one side arm of the insertion section (or preferably two side arms if the insertion section has a two-part design) may be equipped with a locking structure. This locking structure can be formed, preferably with thickened ends, relative to the section of the insertion section extending into the insertion position, particularly in the region of the through hole, and may further have a control ramp for controlling the side arm or insertion section during the insertion overflow position. Upon reaching the insertion position, the locking structure preferably automatically falls into an engaging position behind the relative opening edge due to the spring return force generated by the material selected for the insertion section, thereby locking the functional component.

[0038] The insertion section of the functional component can also be inserted into the through hole from the second opening. In this regard, an arrangement can also be made in which a portion of the functional component is inserted into the through hole from the first opening, and a portion of the functional component is inserted into the through hole from the second opening.

[0039] When a functional component is inserted from the second opening, according to a feasible technical solution, the functional component can protrude outward from the first opening. In this regard, the relevant end region of the functional component can be positioned to protrude beyond the free end region of the grip sleeve. This end region can be the aforementioned functional section. This freely protruding region (functional section) can, for example, further have an opening for suspending or securing a hand tool, for example, to a hook, or further, for example, to a belt. Such a protruding portion of the functional component can also, for example, be used as a measuring instrument or as a lamp.

[0040] In cross-section, the functional component can be substantially U-shaped in its extension perpendicular to the through direction when viewed along the through direction, wherein, in the insertion position, the first side arm passes through the through hole, and the second side arm abuts against the outside of the grip sleeve. In this case, the U-shaped connecting plate of the functional component that connects the two side arms together preferably includes a section of the grip sleeve that restricts the second opening. In this case, the first side arm can further preferably have an extension length that allows the first side arm to protrude beyond the end face of the grip sleeve in the region of its free end.

[0041] Especially when the functional component adopts a U-shaped design in the cross-section, the side arms of the functional component can have different widths (viewed transversely to the insertion direction). In this case, the width of one side arm can be approximately 1.1 to 1.5 times the width of the other side arm, and further approximately 1.2 to 1.3 times.

[0042] Preferably, only the narrower side arm can be inserted into the through hole. This narrower side arm can be the inner side arm of the functional component as viewed from the grip sleeve. In this case, the outer second side arm can form a functional section.

[0043] In another technical solution, the functional component can also be constructed in a two-part or composite manner, having a detachable connection between two or more components. For example, it can be connected by locking, which preferably adjusts automatically when the functional component is arranged on the grip sleeve. In the inserted state, its connector is further preferably located within the through hole, that is, correspondingly located in a hidden area that the user cannot access, or at least cannot access without damage.

[0044] In the case of a functional component, for example, a two-part design, one part of the functional component can be inserted into the through hole through the first opening, and the second part of the functional component can be inserted into the through hole through the second opening.

[0045] In another technical solution, the planar region of the functional component may have a rectangular cross-section. Preferably, it may have a rectangular cross-section, the width of which may be approximately 4 to 8 times the height of the planar region viewed transversely, more specifically, approximately 5 to 7 times or approximately 6 times. Furthermore, the planar region in the cross-section may be further preferably adapted to the cross-section of the through hole holding the recess.

[0046] The planar region may have two side arms that extend generally parallel to each other. These side arms, in a cross-section extending transversely to its longitudinal direction, constrain the planar region to a preferably rectangular cross-section.

[0047] In a preferred embodiment, the side arms extend in a rod-like manner along the longitudinal direction of the planar region or along the insertion or penetration direction.

[0048] One or both side arms may have a locking structure, for example, to allow the functional component to be locked in the insertion position. In this case, the locking structure may be located, for example, in the region of the free end of the side arm.

[0049] According to a feasible technical solution, the functional section can be constructed as a ring. In this way, the functional component can be used, for example, as a suspension member for the hand tool. Furthermore, a guide strap or similar device can also be passed through the ring.

[0050] This functional area can also be constructed as an identification carrier. This identification carrier system can be marked or has labels or symbols pre-installed during the manufacturing process.

[0051] In addition, this functional area can also be an electronic component, such as a lamp or a voltage tester.

[0052] In another technical solution, the functional section may have a cross-section larger than that of the planar region. In this regard, the width of the functional section may, for example, be approximately 1.2 to 2.5 times or more the width of the planar region, but for example, not exceeding 5 times the width of the planar region. The height of the functional section, viewed perpendicular to its width, may further, for example, be approximately 2 to 10 times or more the height of the planar section, but for example, not exceeding 20 times the height of the planar section.

[0053] This functional section can essentially be constructed as a plastic section. It can be made of rigid plastic material.

[0054] Conversely, according to one feasible approach, the locking section can be constructed in a metallic manner, for example, in the form of wire clip components or sheet metal parts.

[0055] The metal engagement section can be encapsulated at its ends by extrusion molding, for example, plastic, to form its functional section.

[0056] It is also possible to construct a structure with two functional sections. Therefore, for example, such functional components can be provided at both ends of the engaging section, wherein the functional sections are separated along the longitudinal direction of the functional elements through the engaging section.

[0057] In addition, this functional component can also be constructed as a tripping spring, for example.

[0058] The same applies to the features of hand tools described above, as well as to supplementary or alternative features related to functional components. In the context of this invention, the ranges, numerical ranges, or multiples given above and below include all intermediate values, particularly those using 1 / 10 increments of the corresponding dimension, or dimensionless values ​​as appropriate. The description of 90 to 150 degrees also includes disclosures such as 90.1 to 150 degrees, 90 to 149.9 degrees, and 90.1 to 149.9 degrees; the disclosure of 3 to 10 times also includes disclosures such as 3.1 to 10 times, 3 to 9.9 times, and 3.1 to 9.9 times. This disclosure can be used to define the aforementioned range limits from below and / or from above, but can also alternatively or supplementarily disclose one or more specific values ​​from the corresponding given range.

[0060] The invention will now be described with reference to the accompanying drawings, which only illustrate embodiments. Any component described based on one of the embodiments may be considered as such in another embodiment if it is not replaced by another component in another embodiment due to the specificity emphasized therein. First, a hand tool 1 in the form of pliers, and more particularly in the form of side-cutting pliers, will be explained and described with reference to FIG1. ​​However, the following embodiments relate not only to this type of hand tool, but also particularly to other pliers, such as flat pliers, pump pliers, combination pliers, wrench pliers, etc., and also, for example, to scissors, such as household or garden shears. Embodiments for designing grip sleeves and / or functional components also relate to hand tools with grip areas, such as knives or screwdrivers.

[0061] Hand tool 1 has two tool parts 2 and 3 arranged intersectingly in the joint area 10. In this case, each tool part 2 and 3 forms a gripping area 4 and 5, which transitions away from the intersection and joint area of ​​tool parts 2 and 3 to the working areas 6 and 7. In the embodiment of hand tool 1 shown in FIG1, the working areas 6 and 7 form a cutting edge.

[0062] The aforementioned tool components 2 and 3 are sometimes referred to as half-tools. Here, the key point is not that they are precisely half, but rather that they are components that complement the other component, particularly in terms of the gripping area of ​​the tool. In particular, with regard to so-called wrenches (see, for example, EP 0 421 107 A2), the tool components may not be constructed in a continuous manner, but rather act on, for example, movable jaws through a leverage ratio.

[0063] The gripping area 4 and the working area 6 form tool component 2; the gripping area 5 and the working area 7 form tool component 3.

[0064] Each gripping area 4, 5 is preferably surrounded by a gripping sleeve 8, 9. This gripping sleeve is preferably made of plastic material and, where appropriate, is directly injection molded onto the tool components 2, 3. Here, known solutions propose manufacturing the gripping sleeves 8, 9 separately using a plastic injection molding process, employing a two-component or multi-component plastic injection molding process, where appropriate. The gripping sleeves 8, 9 can be fitted onto the gripping areas 4, 5 along their longitudinal direction L. Where the tool components are integrally or at least in the gripping areas are made of plastic material, the gripping sleeves 8, 9 can also be integrally molded with the gripping areas.

[0065] In a further preferred embodiment, the grip sleeves 8 and 9 adopt the same design, each grip sleeve having an end 11 facing the working area 6, 7, and, if applicable, facing the connector area 10, and a free end 12 away from the connector area 10.

[0066] At corresponding positions of the hand tool 1 with two tool parts, the grip sleeve 8 has an inner surface 13 facing each other and an outer surface 14 facing away from each other on the gripping areas 4 and 5 of the hand tool 1, as well as a side surface 15 connecting the corresponding inner surface 13 and the corresponding outer surface 14 (see in particular the cross-sectional view in FIG6).

[0067] Regarding the grip sleeve 8, in the region of its free end 12, that is, relative to the closed position of the hand tool shown in FIG2, it can be considered to be located in a plane E that is transverse to the center plane M of the hand tool 1 passing through the rotation axis x in the joint region 10 and oriented therein (see FIG2). The same consideration can also be made with respect to the grip sleeve for the hand tool according to FIG39 or 40, wherein the plane E here is perpendicular to the center plane M of the relevant hand tool.

[0068] The end faces 16 of the gripping sleeves 8 and 9 are substantially extended from the plane E, preferably at an acute angle α of about 30 to 60 degrees, or more preferably about 45 degrees, toward the joint area 10.

[0069] Corresponding to the free end 12 formed through the tapered portion 65 of the grip sleeve 8, in the hand tool according to FIG. 39 or 40, a retaining recess H, preferably in the form of a through hole 17, is constructed in the region of the inner surface 13 or the side surface for accommodating the functional component F in a plug-in retaining manner. In particular, as shown in the cross-sectional view of FIG. 6, when the through hole 17 and the corresponding gripping regions 4 and 5 are projected onto the same plane, for example, onto the central plane M, the through hole 17 can completely overlap with the gripping regions 4 and 5.

[0070] Preferably, the through hole 17, which is preferably substantially linearly extended along the insertion direction r, can be fully seen from the free end 12.

[0071] The through-hole 17 is preferably slit-shaped, and more preferably constructed with a rectangular cross-section, having a width a derived from the longitudinal extension L of the grip sleeves 8 and 9 transversely in the cross-section as shown in FIG. 6, and a height b perpendicular to this. The width a of the through-hole 17 is approximately 0.3 to 0.7 times, more preferably approximately 0.5 times, the maximum width c of the grip sleeve 8 viewed in the same direction between the sides 15. Furthermore, it is more preferably approximately 4 to 8 times, more preferably approximately 6 times, the height b of the through-hole 17. In a further preferred embodiment, the height b is approximately 0.05 to 0.2 times, more preferably approximately 0.1 times, the length d of the through-hole 17. Accordingly, the width c is preferably greater than the width a.

[0072] The through hole 17 has a first opening 18 corresponding to the free end 12 and a second opening 19 pointing in the direction of the connector region 10. The first opening 18 corresponds to the region of the tapered portion 65 of the grip sleeve 8.

[0073] The first opening 18 can form a transition from the through hole 17 to the recess 20 originating from the end face 16 or through the end side plane given by the end face 16.

[0074] In another technical solution, the height b of the through-hole 17, which has a defined opening surface 21 that can also be referred to as the bottom surface of the through-hole 17, is preferably stepless, that is, preferably transitions from the corresponding area of ​​the outer surface of the gripping sleeve, especially the inner surface (or side surface) 13, without shifting along the height direction of the through-hole 17. This surface can be directly the inner surface 13, or, as shown in the figure, the bottom surface 22 of the recess 23 extending from the inner surface 13 (see Figure 7).

[0075] The slit-like through-hole 17 is further laterally restricted by the bridging section 24, which is opposite to the opening surface 21. The bridging section is preferably integrally formed with the grip sleeves 8 and 9 and is made of the same material. In terms of its outer contour, the bridging section smoothly transitions to the contour of the area of ​​the grip sleeves 8 and 9 surrounding the grip areas 4 and 5 (see Figure 6).

[0076] A more significant distance can be achieved between the first opening 18 and the free end 12 through the acute angle of attack described by the end face 16 of each gripping sleeve 8, 9. However, when viewed from the free end toward the central plane M, the first opening 18 forms a portion of the end face of the gripping sleeve 8, 9.

[0077] Different functional components F can preferably be inserted into the through hole 17. Figures 8 to 14 show the insertion layout of a first embodiment of the functional component F together with the grip sleeve side. The functional component F is preferably formed as a plastic injection molded component.

[0078] The functional component F of the first embodiment first has a functional section 25 that is substantially plate-shaped. This functional section, in terms of its surface extension, peripheral design, and thickness, is preferably shaped to fit the recess 20 in the region of the end face 16 on the grip sleeve side. The functional section 25 forms an outer marking surface 26. The marking 27, which is schematically shown only in Figures 8 and 12, is printed on this marking surface, for example, in the form of an icon, or is added during the manufacturing process of the functional component F.

[0079] A engagement section 31 is formed on the functional section 25, opposite to the marking surface 26. In this embodiment, the engagement section 31 forms an insertion section 28, and preferably has two side arms 29 spaced apart from each other transversely to the insertion direction r. The width a' of the entire insertion section 28 in terms of its transverse longitudinal extension is preferably substantially equivalent to the width a of the through hole 17. The side arms 29 realize a planar region 60 that adapts to the cross-sectional design of the functional component F and the through hole 17.

[0080] The side arm 29 or the insertion section 28 formed therefrom preferably forms an obtuse angle β of about 120 to 150 degrees, or more specifically, about 135 degrees, with the functional section 25 (see Figure 11).

[0081] Each side arm 29 may initially extend from the functional section 25 and have a section of length d' including an extension perpendicular to the side arm 29, which is preferably of constant thickness b', and this thickness may be slightly less than the height b of the through hole 17. The aforementioned length d' of the side arm section is preferably adapted to the length d of the through hole 17.

[0082] Subsequently, a locking structure 30 is formed in a region with a relatively constant thickness, corresponding to the end of the side arm 29 opposite to the functional section 25. This locking structure has a larger thickness b'' compared to the aforementioned section and is substantially equivalent to the height b of the through hole 17.

[0083] In the first embodiment, the functional component F extends from the first opening 18 via its insertion section 28 or its side arm 29, and further substantially extends from the free end 12 of the holding sleeves 8 and 9, into the through hole 17. During the insertion of the functional component F along the insertion direction r, the insertion section 28 passes through the slit-like through hole 17 via its end-side locking structure 30, wherein, upon reaching the insertion position, the locking structure 30 of the side arm 29 engages in a locking manner with the opening edge of the second opening 19 (see FIG. 14).

[0084] In this insertion position, the functional section 25 is preferably completely located in the end face side recess 20, so that the marking surface 26 is preferably smoothly accommodated in the circumferential surface of the end face 16 (see Figure 12).

[0085] Figures 15 to 21 show a second embodiment of the functional component F and its arrangement on the grip sleeves 8 and 9. The functional component F in the second embodiment can also be implemented as a plastic injection molded component, but as an alternative, it can also be implemented as a sheet metal bending component.

[0086] With respect to a cross section oriented along the insertion direction r, or with respect to a correspondingly oriented side view according to FIG17, the functional component F is substantially U-shaped, having a first side arm 32 forming an insertion section 28, which forms a planar region 60 adapted to the through hole 17, and a second side arm 33 extending parallel to and at a distance from the first side arm 32. The two side arms 32 and 33 are connected through a connecting plate 34.

[0087] Side arms 32 and 33 extend from the connecting plate 34 and have different lengths d'' and d'''. Therefore, the first side arm 32 forming the insertion section 28 may have a length d'', which is approximately 1.5 to 2.5 times, or more specifically, approximately 2 times, the length d'' of the second side arm 33. Preferably, the length d'' of the first side arm 32 is greater than the length d of the through hole 17, for example, approximately 1.5 to 3 times, or more specifically, approximately 2 to 2.5 times.

[0088] Furthermore, relative to the aforementioned cross section or according to the side view of FIG17, a constant thickness b''' is preferably achieved within the range of the first side arm 32, the connecting plate 34 and the second side arm 33, which is essentially equivalent to the height b of the through hole 17.

[0089] In another technical solution, the width a'' of the first side arm 32 forming the insertion section 28 is preferably smaller than the width a''' of the second side arm 33, wherein the width a'' of the first side arm 32 is further preferably substantially equivalent to the width a of the through hole 17, so that the functional component F can be substantially clamped in the through hole 17 through the insertion section 28.

[0090] The width a''' of the second side arm 33 can be approximately 1.05 to 1.2 times the width a'' of the first side arm 32, and more specifically, approximately 1.1 times.

[0091] In particular, the longer first side arm 32 is provided with a window-shaped notch 35 in the region of its free end opposite to the connecting plate 34. According to the illustrated embodiment, the second side arm 33 may also be constructed with such a notch 36. The functional section 25 having notches 35 and 36 forms a ring 61.

[0092] Unlike the previous embodiments, the functional component F designed in this way is preferably inserted into the through hole 17 from the second opening 19 along the insertion direction r, correspondingly along the inner surface 13 or bottom surface 22 of the recess 23 toward the free end 12. Since the widths of the side arms 32 and 33 are different, the first side arm 32 is defined as the insertion section 28 to be inserted into the through hole 17.

[0093] Preferably, the guiding functional component F passes through the through hole 17 to the connecting plate 34, and stops and restricts the impact on the bridging section 24. In its usage position, the shorter second side arm 33 is preferably placed outside the bridging section 24 and then on the grip sleeves 8 and 9. In this case, it preferably extends along the insertion direction r approximately over the entire extension length of the bridging section 24 until it approximately reaches the bottom of the recess 20.

[0094] The first side arm 32 extends through the through hole 17 and over the second opening 19, preferably also over the recess 20, but more preferably terminates before reaching the aforementioned plane E. The notch 35 forming the ring 61 is accessible based on the end face 16 or the recess 20 extending at an angle β relative to the first side arm 32, so that, when using the notch 35 or the ring 61, for example, the functional component F designed in this way can be used to hang the hand tool 1.

[0095] In another technical solution, an information carrier 37 may also be arranged on the functional component F designed in this way, for example, on the outer side of the second side arm 33. Figure 21 schematically shows the layout of such an information carrier 37 in the form of dashed lines. The information carrier may be, for example, an RFID chip, further for example, an EAN code, or further for example, a positioning chip.

[0096] Furthermore, the functional component F according to the embodiments shown in Figures 22 and 23 may have or be a spring element 38, for example, in the form of a leaf spring, and have a function such as an open spring. For this purpose, the functional component F may, for example, be substantially based on the embodiments shown and described in Figures 8 to 11, wherein one of the side arms 29 of the insertion section 28 is further extended, for example, such that the side arm 29 and the spring element 38 freely protrude from the second opening 19 in the insertion position, and is further preferably supported on the opposing grip area or the inner surface 13 of the grip sleeve located thereon. The spring section freely protruding from the second opening 19 forms the functional section 25.

[0097] According to Figure 24, more preferably, the functional component F based on the aforementioned first embodiment may have a functional section 25 constructed as a cover sheet 39, for which the ring 40 is fixed, for example, to the outside of the functional section 25. This fixing is designed, for example, in a manner that allows it to pivot about a geometrical pivot.

[0098] The functional component F may further be, for example, a preferred non-contact voltage tester 41 (see FIG. 25). For this purpose, the housing 42, which includes the electronics 44, battery 45, and sensor unit 46, may have a cantilever constructed for passing through the through-hole 17, the cantilever having a locking structure 30 at its end. The bridging section 24, together with the housing section 43, is arranged in a manner similar to that of the functional component F in the second embodiment, supported on the bridging section 24, wherein the insertion direction r for securing the voltage tester 41 to the grip sleeves 8, 9 can point from the second opening 19 to the first opening 18. The function of the voltage tester 41 can be triggered or tested via a button 47 protruding from the housing 42.

[0099] Figures 26 and 27 show a two-part functional component F. As shown, this functional component can be an LED light 48 that can be fixed to the grip sleeves 8 and 9. In this case, one component 49 of the functional component F is provided with a light-emitting element 50 forming a first functional section 25, and the other component 51 is provided with a housing 42 forming a second functional section 25, in which an electronic device 44 and a battery 45 are housed, for example. In addition, a button 47 for turning on the light-emitting element 50 can be provided on the component 51.

[0100] Components 49 and 51 or functional section 25 are provided with side arm sections 52 and 53, wherein one side arm section 52 may have a plug-in protrusion 54 and the other side arm section 53 may have a corresponding fitting plug hole 55 (see enlarged view in Figure 26).

[0101] When the component 49 with the light-emitting element 50 is preferably inserted into the through hole 17 through the first opening 18 via its side arm section 52, the second component 51 with the housing 42 is inserted into the second opening 19 via its side arm section 53. The side arm sections 52 and 53 are locked within the through hole 17 by inserting the insertion protrusion 54 into the insertion hole 55. Then, the functional component F, thus designed, is fixed to the grip sleeves 8 and 9. In this case, the side arms 52 and 53 together form the insertion section 28 and the engagement section 31.

[0102] In the locked plug position, the stranded wire 56, which is guided through the side arm sections 52 and 53, is also electrically connected through the plug protrusion 54 and the socket 55, thereby realizing the electrical connection between components 49 and 51.

[0103] Alternatively, the functional component F can be fixed in the through hole 17 or fixed to the grip sleeves 8 and 9 using the through hole 17, for example, by means of a rotating snap or bayonet connection. Figures 28 to 32 show another embodiment with the functional component F, in particular, the functional component can be inserted through the through hole 17 from the second opening 19 along the insertion direction r.

[0104] The insertion section 28 is constructed here as a wire clamp section 58, which has two side arms 29 that are substantially parallel to each other and extend along the insertion direction r, and a functional section 25 on the end side that connects the side arms 29 together. In the illustrated embodiment, this functional section can be used as a loop 61.

[0105] The side arm 29 forms a planar region 60 for mating with the through hole 17.

[0106] The functional component 25, which is substantially U-shaped, preferably has a width e, which is greater than the width e' between the opposing outer surfaces of the side arms 29 in the planar region 60. The width e may, for example, be approximately 1.2 to 1.8 times the width e', and more specifically, approximately 1.5 times (see also Figure 30).

[0107] The side arm 29 is housed and held in the locking member 56 in the region of its free end opposite to the functional section 25. In the inserted position, the locking member is supported on the edge region surrounding the first opening 19, thereby limiting the insertion depth of the functional member F.

[0108] The locking component 56 can be a plastic component. Therefore, the free end of the side arm 29 can be extruded and encapsulated using this plastic to manufacture the locking component 56.

[0109] Furthermore, in the longitudinal cross-sectional view shown in Figure 29, the locking component 56 can be designed in a wedge shape, having a wedge surface that rises from the free end. This wedge surface can be constructed, for example, as a concave thumb seat 57, which allows the functional component F to be moved into the through hole 17 by the thumb resting on it.

[0110] The locking component 56 may also be a functional section 25 of the functional component F, which may have, for example, a marking surface.

[0111] During insertion, the functional section 25, which is in the form of a ring 61, is forced through the through hole 17 in advance. Based on the filament design, the functional section 25 can be compressed so that it can still be pushed through the through hole 17 despite being wider than the through hole 17.

[0112] Simultaneously or alternatively, the width e'' of the through hole 17 may be smaller than, preferably slightly smaller than, the width e' of the planar region 60, or a larger width adjacent to the annulus 61, but more preferably smaller than the width e of the functional component F. During the insertion of the functional component F, as a supplement or alternative to the deformation of the side arm of the functional component F, deformation of the elastic plastic in the wall region of the through hole 17 is achieved as appropriate. Overall, this clamps the functional component F within the through hole 17.

[0113] Through the first opening 18 on the outside, the functional section 25 can be reset based on its elastic reset capability and engage in a locking manner behind the opening 18. Alternatively or in combination, the reset of the elastically deformable plastic material of the grip sleeve can be achieved in the area of ​​the first opening 18. Thus, the functional component F is restrained between the functional sections 25 (locking component 56 and ring 61) which are supported as appropriate at the corresponding opening edges of openings 18 and 19.

[0114] Figures 33 to 35 show an embodiment in which, in particular the planar region 60 and the functional section 25 forming the ring 61 are constituted by the wire clip section 58 according to the aforementioned embodiment, an insertion direction r is generated from the end face 16 of the holding sheath in the direction from the first opening 18 toward the second opening 19.

[0115] The annular region 61 is also widened relative to the planar region 60 or the region limited by the side arm 29. During insertion of the widened functional section 25 through the through-hole 17, the annular region is compressed relative to its width, and / or the through-hole 17 is correspondingly elastically widened. When the annular 61 extends from the second opening 19, the annular 61, or the associated functional section 25, or the elastically deformed plastic, will self-reset.

[0116] In this case, the locking member 56, which is preferably constructed as a plastic injection molded component in contrast to the ring 61, can be molded such that the locking member abuts against the recess 20 on the end side of the grip sleeve in the insertion position of the functional component F (see FIG. 34). As described, for example, in conjunction with the embodiments in FIG. 8 to 14, the outward surface of the locking member 56 forming the second functional section 25 can, for example, provide a marking surface 26.

[0117] The functional component F of the embodiments shown in Figures 36 to 38 is essentially based on the embodiments described above in Figures 28 to 32, but in which the wire clip section 58, which forms the side arm 29 and the annular functional section 25, is provided with a plate section 59.

[0118] The plate section 59 is also provided with a planar region 60 having a width e' that extends in the through hole 17 in the insertion position. This planar region is connected at its end to a wider annular functional section 25, which has a notch 35. The description made with respect to the embodiments in Figures 28 to 31 also applies to the relationship between the width e of the functional section 25 and the width e' or the width of the through hole 17 when viewed in the same direction.

[0119] In this embodiment, the plate section 59 is also separated from the functional section 25 and is held in the locking member 56, which may form another functional member 25 as appropriate.

[0120] The insertion process also begins from the second opening 19, where the functional section 25, based on its width e which is larger than the opening width of the through hole 17, can also be compressed in a way that allows for elastic reset.

[0121] The functional component F in the embodiments shown in Figures 28 to 38 preferably has two functional sections 25 spaced apart from each other, which are interconnected by planar areas 60 forming engaging sections 31, in the form of wire clips or sheet metal sections. Although Figures 1 to 38 show embodiments of hand tools having two tool components 2 and 3 in the form of pliers 62, the embodiments shown in Figures 39 and 40 relate to a hand tool 1 having only one tool component 2. Figure 39 shows, for example, a cable stripper 63. Figure 40 shows a screwdriver 64.

[0122] The handle of the knife or screwdriver is formed by a grip sleeve 8, which surrounds the grip area 4 of the tool component 2. The working area 6 consists only of the blade or screwdriver shaft.

[0123] Here, the functional component F can also be arranged on the end side of the gripping area 4. Corresponding to the free end 12, a through hole 17 is formed in the gripping sleeve 8, through which the functional component F can be inserted according to the aforementioned embodiment.

[0124] Figures 39 and 40 show the functional component F according to the embodiment in Figure 31, but the layout of the functional component F according to, for example, Figures 15, 24, 25, 26 or 34 can also be adopted.
