[0001] The present invention relates to a hand-held circular saw having a saw blade receiving portion, which is used to fix the saw blade and can be rotated about a drive axis by means of a drive component, wherein a protective cover is provided, which surrounds a chip guide space, and a saw blade receiving area is formed in the chip guide space, and the saw blade receiving area is arranged and constructed to receive the saw blade in the working position, wherein the protective cover has a side outer wall, and the side outer wall limits the chip guide space on the side facing away from the drive component, wherein the lighting component is provided with at least one light-emitting element to at least partially illuminate the cutting area of ​​the hand-held circular saw, and wherein the light-emitting element is arranged behind the saw blade receiving area and / or the cutting area along the feed direction of the hand-held circular saw. Background Art

[0002] JP2022-46093 discloses a handheld circular saw with a protective cover that encloses a chip guide space. A saw blade is housed in the chip guide space. A light-emitting assembly is arranged in the chip guide space behind the saw blade in the feed direction. The light-emitting assembly emits light transversely to the saw blade's axis of rotation, toward both sides of the saw blade. Consequently, the saw blade, located in the light path of the light-emitting assembly, casts a shadow on the workpiece being machined. Summary of the Invention

[0003] The object of the present invention is to provide a hand-held circular saw of the type mentioned at the outset which offers improved operating comfort with a high degree of operational reliability.

[0004] This object is achieved in that the lighting component is arranged and oriented so that the light emitted by the lighting element is mainly emitted in the feed direction of the hand-held circular saw, and the light emitted by the lighting element extends at least partially, preferably completely, in a light guiding area, which is separated from the dust guiding area of ​​the chip guide space.

[0005] By arranging the light-emitting element behind the saw blade receiving area and / or behind the cutting area, as well as behind the saw blade, in the feed direction, the entire working area of ​​the saw blade can be illuminated as desired by the user. Furthermore, illumination is improved by emitting the light emitted by the light-emitting element primarily in the feed direction of the handheld circular saw. This improves operating comfort even in working positions with poor visibility. By causing the light emitted by the light-emitting element to extend at least partially, and preferably completely, in a light guidance area separated from a dust guidance area, the light path is not affected by chips separated from the workpiece during machining operation. Consequently, the working area, in particular the cutting area, can be illuminated reliably and without glare for the user of the handheld circular saw, even during machining operations.

[0006] Preferably, the light emitting element is arranged separately from the dust guiding region of the chip removal guide space so that the light emitting element is not soiled.

[0007] According to a variant of the present invention, the light-emitting element can illuminate the cutting zone of the handheld circular saw on the outside of the side outer wall. The cutting zone is understood to be the area where the saw blade cuts the surface of the workpiece to be machined when the handheld circular saw is positioned on the workpiece to be machined. Preferably, the cutting zone is illuminated on the outside of the side outer wall where the saw blade cuts into the workpiece. For example, an adjustment device can be provided to focus the light-emitting element in this area.

[0008] It can preferably be provided that the protective cover has, on its outer side facing away from the chip guide space, a rear area marking for marking the rear end of the cutting area in the feed direction and a front area marking for marking the front end of the cutting area in the feed direction, and the light emitted by the light-emitting element illuminates at least a sub-area, preferably at least the entire area, between the two area markings.

[0009] The handheld circular saw according to the present invention can be designed with a light carrier that holds a light element in an area facing away from the chip guide space. The light element is mounted so that it is easily accessible to the user. Furthermore, the light element effectively illuminates the working area of ​​the handheld circular saw.

[0010] If it is arranged that the lamp carrier has a fastening assembly, the light emitting assembly is replaceably connected to the fastening assembly, and now the user can appropriately access the light emitting assembly when necessary. If the light emitting assembly is no longer needed, the user can disassemble the light emitting assembly and place it aside.

[0011] Preferably, it can be provided that the light-emitting element is held in the region of the lateral outer wall of the protective cover, particularly preferably fixed to the lateral outer wall. Preferably, the light-emitting element is then detachably connected to the protective cover. In particular, sawing in the region of the outer side of the protective cover near the wall is not affected.

[0012] Preferably, the light-emitting element is pivotably connected to the hand-held circular saw, either indirectly or directly via the cutting region. This allows for the light beam of the light-emitting element to be suitably adjusted. For this purpose, it can be provided that the lamp carrier comprises a support element, which is coupled to a support element, in particular a protective cover, of the hand-held circular saw via a fastening element, a counter-support element is movably connected to the support element, the light-emitting assembly is preferably releasably coupled to the counter-support element, and the support element and the counter-support element form an adjustment bearing for adjusting the position of the light-emitting assembly.

[0013] For a suitable focusing of the light assembly, it is advantageous if the light assembly is adjustable, in particular pivotable, about at least one rotational degree of freedom relative to a support element of the hand-held circular saw, in particular relative to the protective cover. Additionally or alternatively, however, it is also conceivable to provide an adjustment assembly by means of which the light assembly can be moved translationally, in particular to achieve a suitable alignment with the protective cover.

[0014] For space-saving positioning of the lighting component, it can be provided that the protective cover has a suction connection including a connecting tube behind the saw blade receiving area in the feed direction, the connecting component is preferably replaceably fixed to the connecting tube, the connecting component has a connecting element, and the lamp carrier is preferably replaceably fixed to the connecting element.

[0015] To reduce component costs, it can be provided that the connecting assembly has a channel section for chip removal, the channel section carrying the connecting element, a carrier connected to the connecting element at a distance from the channel section, the carrier having a fastening receptacle for coupling a lamp carrier.

[0016] A particularly preferred embodiment of the present invention provides that the drive assembly is pivotably coupled to the guide plate by means of a rear bevel bearing arranged behind the saw blade receiving area in the feed direction, so that the drive assembly can be pivoted relative to the guide plate to set the bevel angle. The bevel bearing has a stationary support and a movable support, wherein the stationary support is coupled to the guide plate and the movable support is coupled to the drive assembly. The light element is attached to the stationary support or to the movable support. The light element is positioned so that the light is emitted substantially or entirely in the feed direction. Furthermore, the light element is mounted in a space-saving manner and does not or only insignificantly affect the movement space of the hand-held circular saw.

[0017] Some handheld circular saws are designed with a protective cover having a delimiting element on its underside facing the workpiece, which is curved toward the cutting area. A variant of the present invention utilizes a protective cover designed in this manner, wherein the light-emitting element is arranged so that it emits its light along the delimiting element in the feed direction. This allows the light to pass very closely along the actual position of the saw blade, thereby improving working precision.

[0018] If the lighting assembly comprises a lamp housing, which accommodates the light element, and the lamp housing comprises or carries a fastening section, by means of which the light element is replaceably fastened to a lamp carrier, wherein preferably the lamp carrier is arranged on the outer side of the protective cover facing away from the chip guide space, preferably on the outer side of the lateral outer wall facing away from the chip guide space, the user can then easily attach or detach the light element to the handheld circular saw. In addition, the user can use the lighting assembly separately in the form of a flashlight.

[0019] If it is provided that the lamp housing is replaceably connected to the lamp carrier by means of a magnetic connection, the installation of such a lighting assembly can be achieved particularly simply. If it is further provided that the lamp housing has a form-fitting connection element, which forms a form-fitting connection between the lamp housing and the lamp carrier transverse to the action of the magnetic forces, the position of the lamp housing can be reliably maintained by the form-fitting connection even in the event of external mechanical stresses, such as vibrations.

[0020] A particularly preferred embodiment of the present invention provides that the protective cover separates the magnetically connected ferrous component from the magnetically connected magnetic component. In this case, the magnetic component (or ferrous component) can remain concealed on the inner side of the protective cover facing the chip guide channel (or be integrated into the protective cover itself). As a result, the magnetic component (or ferrous component) does not cause any visual disturbance.

[0021] In order to avoid or prevent the risk of injury when the light-emitting element is activated, a variant of the invention provides that the light housing carries an electrical switch in its region facing away from the guide plate of the hand-held circular saw.

[0022] For optimal positioning of the light element, it can be provided that the lamp housing holds the light element in the region of its end facing the guide plate in the region of the free end of the lateral outer wall and laterally alongside the lateral outer wall.

[0023] A possible variant of the present invention can be provided in which a cover is arranged in the chip removal space, the cover at least partially separating the light guide area from the dust guide area of ​​the chip removal guide space. Preferably, the light-emitting element is arranged outside the chip removal guide space, or the cover or another cover element separates the area in the chip removal guide space where the light-emitting element is arranged, so that the light-emitting element is arranged separately from the dust guide area. In this case, the light-emitting element is integrated behind the protective cover in a space-saving manner, the light-emitting element remaining separated from the chip removal guide channel to avoid contamination of the light-emitting element and / or an influence on the light path.

[0024] In order to achieve suitable illumination in the area outside the protective cover in this arrangement, it can be provided that the protective cover, in particular the side wall, has a light passage through which light from the light-emitting element passes and is guided out of the chip guide space. Preferably, the light passage is provided at least partially on a delimiting element, which is configured at the lower free end of the side wall in the form of a bend pointing inwardly toward the chip guide space, so that the area near the cutting area of ​​the saw blade can be illuminated.

[0025] A conceivable variant of the present invention provides that the protective cover, in particular the side outer wall, has at least one fastening receptacle to which the light module is fastened, wherein the fastening receptacle is introduced into the protective cover as a recess or as a depression. This allows for space-saving installation of the light module. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] Figure 1A typical working situation is shown in which an operator P uses a handheld circular saw 10 to process a workpiece 45 located on a work table 44. The handheld circular saw 10 is used to separate sections 46 of the workpiece 45. For this working process, the guide rail 40 is placed with its rail underside 42 on the upper side of the workpiece 45. The handheld circular saw 10 rests on the rail upper side 41 of the guide rail 40. The handheld circular saw 10 can be guided in the longitudinal direction of the rail on a guide element 43 of the rail 40 in a known manner.

[0041] According to the present invention, a light emitting assembly 70 is mounted on the handheld circular saw 10 , and light can be guided to the upper side of the workpiece via the light guiding area 24 . 13 by the light emitting assembly.

[0042] Figure 2 and Figure 3 The technical concept of a hand-held circular saw 10 is shown. As can be seen from the figure, the hand-held circular saw 10 has a guide plate 11, with which the hand-held circular saw can be placed on a guide rail 40. The hand-held circular saw 10 has a guide receptacle on its downward-facing support side 12, which interacts with a guide element 43 of the guide rail 40 for longitudinal guidance. The guide plate 11 has a retaining structure in the area of ​​its top side 13, via which the drive assembly 20 can be connected to the guide plate 11.

[0043] The drive assembly 20 includes a drive motor 21, which can rotate the saw blade support 33. The saw blade 30 is fixed to the saw blade support 33 in a replaceable manner. Figure 2 The position of the drive axis 34 is shown, about which the saw blade 30 can rotate. The saw blade 30 has a saw blade inner side 31 on its side facing the drive motor 21 and a saw blade outer side 32 opposite thereto, which can be rotated. Figure 2 The inner side 31 of the saw blade is Figure 3 Shown in.

[0044] The saw blade 30 is mounted in the saw blade receiving area 24.12 of the protective cover 24 in the installed state. The present hand-held circular saw 10 is a plunge saw, for which the drive assembly 20 can be driven with the saw blade 30 around a direction perpendicular to the direction of rotation. Figure 2 and Figure 3 The saw blade 30 is pivoted about the pivot axis of the drawing plane so that the saw blade 30 is at least partially pivoted out of the protective cover 24 into the insertion position. This insertion position with maximum pivoting of the saw blade 30 is Figure 2 and Figure 3 Shown in.

[0045] The protective cover 24 may have a connecting pipe 22.1, which is preferably integrally connected to the protective cover 24. The connecting pipe 22 serves as a suction connection 22. A coupling 22.1 can be removably fastened to the suction connection 22 by means of a locking element 22.3. The coupling 22.2 may be part of a suction hose of a chip extraction device or a connecting piece for such a suction hose. During machining operations, the chip extraction device removes the chips from a chip channel 25 enclosed by the protective cover 24 and spatially connected to a chip guide space 24.11.

[0046] like Figure 2 As shown, the protective cover 24 can form a lateral outer wall 24.6 which delimits the chip guide space 24.11 on the side facing away from the drive assembly 20. In other words, the lateral outer wall 24.6 delimits the chip guide space 24.11 in the region of the outer side 32 of the saw blade.

[0047] The lateral outer wall 24 . 6 extends essentially perpendicularly to the drive axis 34 .

[0048] The lateral outer wall 24.6 has a strip-shaped delimiting element 24.7 at its lower end. The delimiting element 24.7 forms an outer delimiting surface 24.8, which is angled inwardly toward the saw blade 30.

[0049] Figure 2 It is also shown that the lateral outer wall 24.6 carries two markings, namely a rear area marking 24.1 and a front area marking 24.2. The cutting area of ​​the saw blade 30 is marked between the two area markings 24.1 and 24.2, which are visible to the user P. The two area markings 24.1 and 24.2 thus show the rear and front saw blade boundaries in the maximum insertion position of the saw blade 30.

[0050] like Figure 4 As shown, in the front cutting area of ​​the saw blade 30, there is a recess 24.3 in the lateral rear wall 24.6, through which the front cutting area of ​​the saw blade 30 is visible. The recess 24.3 can be covered by a removable and transparent window 24.4. This window 24.4 can carry a front area marking 24.2.

[0051] For example, the transparent window 24.4 can separate the light guiding area 24.13 from the dust guiding area of ​​the chip removal guide space 24.11, wherein it is preferably provided that the light-emitting element 71 is arranged outside the chip removal guide space 24.11 so that the light-emitting element is arranged separately from the dust guiding area, in particular separated from the chip removal guide space 24.11 by the transparent window 24.4.

[0052] Therefore, the transparent window 24.4 forms a light passage 24.10 in the protective cover 24, in particular in the side wall 24.6, through which the light of the light-emitting element 71 passes, wherein it is preferably provided that the light passage 24.10 is arranged on the limiting element 24.7, and the limiting element is constructed in the form of a curved portion pointing inwardly in the direction of the chip removal guide space 24.11 at the lower free end of the side wall 24.6 or the transparent window 24.4.

[0053] Figure 4 It is also shown that the protective cover 24 can have an upper covering area 24 . 5 which forms the aforementioned chip guide channel 25 .

[0054] Figure 2 and Figure 3 Also show that drive assembly 20 can be connected with guide plate 11 to realize bevel cutting with swinging. For this reason, drive assembly 20 is connected with guide plate 11 by means of rear bevel bearing 26 and front bevel bearing 27.

[0055] The rear bevel bearing 26 has a stationary support part 26.1, which is connected to the guide plate 11. A movable support part 26.2 is connected to the stationary support part 26.1 by means of a pivot bearing, wherein the movable support part 26.2 is coupled to the drive assembly 20.

[0056] The front bevel bearing 27 is constructed in the same manner and has a fixed support 27.1 and a movable support 27.2. In order to lock the set pivot position, the two bevel bearings 26 and 27 each have a locking device 26.3, 27.3.

[0057] The arrangement and guidance of the handheld circular saw 10 is simplified by means of the handle 23 of the drive assembly 20 , wherein the handle 23 can also have a trigger for activating the drive motor 21 in a conventional manner.

[0058] Figures 4 to 4b It is shown that the lighting assembly 70 can be replaceably connected to the handheld circular saw 10 .

[0059] The light emitting assembly 70 includes a light emitting element 71 , which is mounted in a lamp housing 75 .

[0060] The light emitting assembly 70 can be replaceably connected to the handheld circular saw 10. The light emitting assembly 70 is fixed using the connecting assembly 50. Here, the connecting assembly 50 is connected to the handheld circular saw 10. The lamp carrier 60 can be replaceably mounted on the connecting assembly 50. The lamp carrier 60 can have another interface, and the lamp housing 75 can be replaceably fixed to the other interface.

[0061] In the illustrated embodiment, the connecting assembly 50 has a carrier part 57 with a fastening receptacle 58. A fastening element 61 of a lamp carrier 60 can be fastened to the carrier part 57 by means of a fastening element 62. As shown in the figures, the fastening element 62 has a screw which is screwed into the fastening receptacle 58.

[0062] In order to enable the lamp carrier 60 to be movable relative to the connecting assembly 50 , a pivot bearing, a rotary bearing, a linear guide or a combination of a pivot bearing or a rotary bearing and a linear guide may be provided.

[0063] In the present embodiment, a pivot bearing is used, wherein the pivot axis is formed by the longitudinal center axis of the fixing element 62 designed as a fastening screw. Figure 4a and Figure 4b As shown, the lamp carrier 60 can be adjusted in a snap-fit ​​manner relative to the connecting component 50. For this purpose, it can be provided that the connecting component 50 has a snap-fit ​​portion 59. A mating snap-fit ​​element of the lamp carrier 60 engages in the snap-fit ​​portion 59 to enable snap-fit ​​adjustment.

[0064] Figure 4b It is also shown that the lamp carrier 60 can also have a supporting element 63, which is pivotably coupled to a counter-supporting element 64. The counter-supporting element 64 indirectly or directly carries the lamp housing 75 and is used to pivotally set the lighting assembly 70. Figure 4a and Figure 4b As shown, according to a variant of the invention, provision can be made for the lighting assembly 70 to be adjustable about two pivot axes (two rotational degrees of freedom) in order to suitably focus the light emitted by the lighting assembly 70 .

[0065] The lighting assembly 70 is fixed using a fastening assembly 65. Preferably, the fastening assembly 65 is mounted on a counter-support element 64 and is configured to establish a releasable connection with a lamp housing 75. In the present embodiment, the fastening assembly 65 forms a clamp.

[0066] In a variant of the present invention, the connecting assembly 50 can form a channel section 51. The channel section 51 can be releasably connected to the coupling head 22.1, such as Figure 4a For example, a locking element 22.3 can be used to connect the channel section 51 to the coupling head 22.1.

[0067] The channel section 51 has a plug projection 52 that can be inserted into the coupling head 22.1. This insertion movement is limited by a stop 53 of the channel section 51. On the side of the stop 53 opposite the plug projection 52, a connecting piece 54 is provided that can be used to couple the coupling piece 22.2.

[0068] In order to arrange the coupling 22.2 on the coupling head 22.1 so that it cannot rotate relative to each other, the connecting assembly 50 has a positive connection element that cooperates with a counterpart positive connection element of the coupling 22.2. For example, the positive connection element can be configured as a toothing 55 that engages in the front end of the connecting pipe 54.

[0069] Figure 4a It is also shown that the connecting assembly 50 carries a connecting element 56 , to which a carrier 57 is fixed, preferably integrally molded. The connecting element 56 can be integrally molded onto the stop 53 .

[0070] To install the light assembly 70, the connecting assembly 50 is fixed to the hand-held circular saw 10 as described above. The lamp carrier 60 can then be fixed to the supporting portion 57 of the connecting assembly 50 by means of the fixing element 62. The light assembly 70 is fixed by means of the fastening assembly 65. The user P can oscillate the light assembly 70 to appropriately align the light cone generated by the light assembly 70 to illuminate the sawing area.

[0071] As can be seen from the figure, the light assembly 70 is arranged behind the saw blade 30 in the feed direction of the handheld circular saw 10. The light emitted by the light assembly 70 is directed substantially in the feed direction V, so that the light at least partially illuminates the sawing area between the two zone markings 24.1 and 24.2. In particular, the user P can set the light assembly 70 to sufficiently illuminate the area around the front zone marking 24.2.

[0072] Figure 5 A section is shown perpendicular to the support side 12 of the guide plate 11 through the protective cover 24 and through the drive axis 34 .

[0073] As shown, different lighting areas L1, L2, and L3 are formed depending on the arrangement of the lighting assembly 70 relative to the lateral outer wall 24.6. Lighting areas L1 and L2 form particularly suitable lighting areas according to the present invention. Lighting area L1 is bounded by the lateral outer wall 24.6 and the surface of the workpiece 45 to be machined. Lighting area L2 is bounded by the workpiece surface and the boundary surface 24.8 of the boundary element 24.7 and extends to or almost to the side of the saw blade receiving area 24.12 facing the lateral outer wall 24.6 or to the outer side 32 of the saw blade.

[0074] The light emitting area L3 is less suitable because it does not illuminate the workpiece surface in the cutting area.

[0075] By following Figures 4 to 4b The embodiment can particularly illuminate the luminous area L1.

[0076] Figure 6 and Figure 6aAn embodiment is shown for illuminating in particular the luminous region L2 and partially illuminating the luminous region L1. In the figures, identical components are denoted by identical reference numerals, so that reference will be made to the above to avoid repetition.

[0077] As shown, the light assembly 70 is connected to a portion of the rear miter bearing 26. Preferably, the light assembly 70 is connected to the movable support 26.2 so that the support and the protective cover 24 swing together when the miter angle of the handheld circular saw 10 is set.

[0078] The figures show that the lighting assembly 70 is preferably arranged at least partially in the area formed by the extension of the lateral outer wall 24.6 and the boundary surface 24.8 of the boundary element 24.7. The lighting element 71 emits its light in the feed direction V or substantially in the feed direction V to illuminate the lighting area L2 and, if necessary, also partially illuminate the lighting area L1.

[0079] exist Figure 7 and Figure 7a Other variations of the present invention are shown in FIG. Figure 7 and Figure 7a An embodiment is shown for illuminating, in particular, the luminous areas L1 and L2. In the figures, identical components are denoted by identical reference numerals, so that reference will be made to the above to avoid repetition.

[0080] As shown in the figure, the lighting assembly 70 can be replaceably connected to the protective cover 24, preferably to the lateral outer wall 24.6 of the protective cover 24. For this purpose, the lighting assembly 70 has a fixing section 76 that can be replaceably connected to the protective cover 24.

[0081] The lighting assembly 70 has a lamp housing 75 in which the lighting element 71 is mounted. A power supply device, in particular a battery, can also be arranged in the lamp housing 75 to supply power to the lighting element 71 .

[0082] The lamp housing 75 has a contact surface 72 in the region of the mounting side, which is arranged and designed to rest against the outer side of the lateral outer wall 24.6. A positive-locking element 73 may be present in the region of the contact surface 72, which rests against a counter-positive-locking element of the protective cover 24 in order to prevent the lamp housing 75 from moving in the plane of the outer side of the lateral outer wall 24.6. The positive-locking element 73 may be designed to engage a recess in the contact surface 72. The counter-positive-locking element may be formed by a raised portion projecting onto the outer side of the lateral outer wall 24.6.

[0083] The connection between the light emitting assembly 70 and the protective cover 24 can be magnetic. For example, the lamp housing 75 can have a magnet 74 (or an iron component) that cooperates with the iron component (or magnet) of the protective cover 24 to form a magnetic connection.

[0084] In the present embodiment, the iron component (or magnet 74) is attached to the outside of the lateral outer wall 24.6 and preferably also forms a mating positive connection element at the same time. However, it is also conceivable that the iron component (or magnet 74) is at least partially integrated into the material of the lateral outer wall 24.6 or is arranged on the inside of the lateral outer wall 24.6 facing away from the outside of the lateral outer wall 24.6.

[0085] The lamp housing 75 forms a cover section on its upper side, which is used together with the switch 77 to switch the light-emitting element 71 on or off.

[0086] Preferably, in the mounted state of the lighting assembly 70, the lamp housing 75 carries the lighting element 71 at its end facing the guide plate 11. Particularly preferably, the lamp housing 75 holds the lighting element 71 in the region of the boundary surface 24.8 and thus can also at least partially illuminate the lighting area L2, as shown in FIG. Figure 7a This is shown by the light guiding area 24.13 which is shown symbolically here.

[0087] The figure also shows that it is advantageous to arrange the switch 77 on the light housing 75 on the side facing away from the guide plate 11 , since the user P can activate the light-emitting element 71 away from the cutting area.

[0088] Figure 8 Another variant of the present invention is shown. Here, a light emitting assembly 70 is shown, which is used in accordance with Figures 1 to 5 Therefore, reference is made to the above description of the design of the hand-held circular saw 10.

[0089] like Figure 8 As shown, the light assembly 70 includes a lamp housing 75, which carries at least one protruding form-fitting connection element 73. The protective cover 24, preferably the lateral outer wall 24.6, has one or more fastening receptacles 24.9, which can be configured, in particular, as recesses. To secure the lamp housing 75, the form-fitting connection elements 73 engage in the fastening receptacles 24.9. The form-fitting connection elements 73 and the fastening receptacles 24.9 preferably form a releasable connection, allowing the user P to selectively install the light assembly 70.

[0090] Preferably, the fastening receptacle 24 . 9 and the form-fitting connection element 73 form a snap-in connection, which simplifies assembly or disassembly.

[0091] like Figure 8 As shown, the form-fitting connection element 73 can have a contact surface 72 which prevents a displacement of the lamp housing 75 in the direction of the plane formed by the outer side of the lateral outer wall 24 . 6 .

[0092] Figure 9Another embodiment of the present invention is shown, which can be applied in Figures 1 to 5 In order to avoid repeated reference to the above structure of the handheld circular saw 10.

[0093] As shown, a cover 78 is arranged within the chip guide space 24.11. The cover at least partially separates the light guide area 24.13 from the dust guide area of ​​the chip guide space 24.11. Preferably, the cover 78 also separates the light-emitting element 71, and in particular the entire light-emitting assembly 70, from the chip guide space 24.11. This allows the light-emitting element 71 to be protected from the chip guide space 24.11.

[0094] The figures show that the cover 78 can be fastened to the inner side of the lateral outer wall 24 . 6 .

[0095] Figure 9 The light-emitting element 71 is shown to emit its light through a light-guiding area 24.13 enclosed by the top cover 78. The protective cover 24 has a light-passing portion 24.10, which is preferably configured as a notch in the delimiting element 24.7. Through this light-passing portion 24.10, the light from the light-emitting element 71 shines into the area outside the protective cover 24 and is preferably guided into the light-emitting area L2 and / or the light-emitting area L1 to generate light on the upper side of the workpiece 45.

[0096] In the aforementioned embodiment of the present invention, the lighting assembly 70 is arranged and oriented such that the light emitted by the lighting element 71 is emitted primarily in the feed direction V of the handheld circular saw 10. The light emitted by the lighting element 71 extends at least partially, and preferably completely, within the light guide area 24.13, which is separate from the dust-guiding area of ​​the chip guide space 24.11. The lighting assembly 70 holds the lighting element 71 behind the cutting area, viewed in the feed direction.
