Description

Technical Field

[0001] The invention relates to a light emitting module for a handheld circular saw. Background Art

[0002] JP2022-46093 discloses a hand-held circular saw with a protective cover, which surrounds a chip guide space. A saw blade is accommodated in the chip guide space. A light-emitting component is arranged in the chip guide space behind the saw blade in the feed direction. The light-emitting component emits its light transversely to the rotation axis of the saw blade to both sides of the saw blade. Therefore, the saw blade located in the light path of the light-emitting component casts a shadow on the workpiece to be processed. With this arrangement, the working area located on the side of the hand-held circular saw is not sufficiently illuminated. Summary of the invention

[0003] The object of the present invention is to provide a lighting module for a handheld circular saw, by which a user can appropriately illuminate a working area beside the handheld circular saw according to needs.

[0004] This object is achieved by a lighting module according to technical solution 1. Therefore, a lighting module having a lamp housing is proposed, a power source is installed in the lamp housing, and a light-emitting element is electrically connected to the power source, wherein the light-emitting element is arranged to emit light in an emission area on one side of the lamp housing to a working area of ​​a hand-held circular saw, and wherein the lamp housing has a fixing section, the fixing section forms a fixing side having an abutment surface, and the abutment surface is arranged and oriented to be detachably fixed on a fixing surface of the hand-held circular saw.

[0005] Therefore, a light module is provided for the user, which the user can mount on the outside of the hand-held circular saw as required in order to appropriately illuminate the working area. The light module forms an independent unit with a power supply, which is therefore independent of the power supply of the hand-held circular saw. In certain working situations, for example when sawing close to a wall or when sawing at a large angle, it may happen that the light module, for example, collides with a workpiece. The user can then simply remove the light module from the circular saw and carry out the sawing work. The light module can then be simply placed on the hand-held circular saw again with its fixed side. The user can thus mount the light module as required and optimally illuminate the working area. Preferably, the hand-held circular saw has a mechanical interface to which the light module can be mounted with its fixed side. Preferably, the preset interface is arranged on the outer side of a protective cover of the hand-held circular saw, which covers the saw blade.

[0006] Preferably, the light module is designed in a rod-like shape, so that the light module can be easily handled when it is mounted on the handheld circular saw and has a compact design.

[0007] Preferably, it can be provided that the contact surface of the light housing is designed to be flat, in order to bear flatly against a flat fastening surface of the hand-held circular saw.

[0008] According to a preferred variant of the invention, it can be provided that the fixing side extends between the housing upper side of the lamp housing and the housing lower side of the lamp housing, and that the emission region of the light-emitting element is arranged in the region of the housing lower side of the lamp housing, preferably in a region which is spaced apart from the housing lower side by less than 30 mm in the direction of the housing upper side of the lamp housing. In this arrangement, the light-emitting module can be mounted on the outer side of the hand-held circular saw so that the housing lower side of the lamp housing is located near above the workpiece to be processed. The emission region is therefore also arranged near above the upper side of the workpiece. The emission region is therefore arranged so that the light emitted by the light-emitting element can be guided onto the upper surface of the workpiece to achieve optimal illumination. Ideally, the light-emitting element emits its light in the feed direction of the hand-held circular saw so that the light-emitting element is not invisible to the user.

[0009] In this case, it can be provided that the lamp housing carries a switch for activating and deactivating the light element. Preferably, the switch is arranged at least 30 mm from the underside of the lamp housing and / or the switch is arranged in the region of the housing upper side of the lamp housing. Thus, the user can switch the light module arranged on the hand-held circular saw on and off away from the cutting area of ​​the hand-held circular saw, which eliminates or at least significantly reduces the risk of injury.

[0010] It is provided that the cone axis of the light cone generated by the light module extends in a direction parallel to the fastening side, so that the light emitted by the light element can be guided intensively on the fastening side, which leads to better illumination of the cutting area when the light module is arranged on the handheld circular saw.

[0011] According to a preferred variant of the invention, it can be provided that the cone axis of the light cone generated by the light module is pivotable about a lamp housing axis extending parallel to the fastening side and / or between a housing underside and a housing top side of the lamp housing.

[0012] The light module can be easily handled if it is dimensioned such that its maximum outer dimension is less than 90 mm, wherein preferably the maximum width and depth are each less than 40 mm and the maximum length is less than 90 mm. Preferably, the depth of the light module is the dimension extending perpendicularly to the fastening side and / or the length of the light module is the dimension extending parallel to the fastening side. The light module protrudes only slightly on the outside of the hand-held circular saw and only slightly delimits the working area.

[0013] The width of the light module preferably extends in the feed direction in the installed state. For example, the height of the light module can extend perpendicularly or transversely to the workpiece surface of the workpiece to be processed.

[0014] A possible variant of the invention can be designed so that the fastening side, the light emission direction, in particular the cone axis of the light cone generated by the light module and the longest dimension of the lamp housing extend perpendicularly to one another. Such a light module can be fastened in a particularly space-saving manner on the outside of a protective cover that covers the saw blade of a hand-held circular saw.

[0015] A secure fit of the light module to the machine tool is provided if the light housing has a form-fitting connection element in the region of the fastening side, which is designed and arranged to interact with a counter-form-fitting connection element of a hand-held circular saw or a similar machine tool to form a form-fitting connection in the direction of the plane of the fastening side. In particular, a secure fit of the light module to the machine tool can be ensured even in harsh applications with low fastening forces perpendicular to the fastening side.

[0016] In this case, it can also be provided, for example, that the form-fitting connection element is designed to engage in a recess in the fixing side of the lamp housing. A mating form-fitting connection element of the hand-held circular saw can engage in the recess to produce a form-fitting connection. The mating form-fitting connection element can be formed, for example, by a component that protrudes from the hand-held circular saw. In particular, the mating form-fitting connection element can be a separate component that is mounted or can be mounted on a protective cover covering the saw blade. In this way, the mating form-fitting connection element can be easily added to existing hand-held circular saws in order to be able to arrange the lighting module according to the invention on the hand-held circular saw. However, it is also conceivable that the mating form-fitting connection element is molded in one piece on the protective cover of the hand-held circular saw.

[0017] According to the invention, the lighting module has a mechanical interface, by means of which the lighting module can be detachably connected to the handheld circular saw. Therefore, in particular, the lamp housing can carry a connecting component, which is configured to form a releasable connection with the handheld circular saw or similar machine tool.

[0018] Preferably, the connection component is a magnet or a ferromagnetic component, which is preferably held in the lamp housing or at least partially embedded in a wall element of the lamp housing. Such a magnetic connection is easy to operate for the user and can also be used reliably in harsh construction site work.

[0019] However, it is also conceivable that the connecting component is part of a chain connection or that the connecting component is part of an adhesive connection or that the connecting component is part of a snap connection, in particular a snap element.

[0020] If the light cone emitted by the lighting element is designed in such a way that at least 50% of the light is emitted at an angle of less than 10°, a focused light cone is produced which allows particularly good illumination of the workpiece surface.

[0021] As mentioned above, the lighting module has its own power supply, which can be formed, for example, by a battery. In order not to suddenly switch off the lighting module in the case of an excessively low charge level of the battery and thus scare the user, a variant of the invention can provide a regulating device which dims the lighting element in stages or continuously when the charge level of the power supply falls below a preset level. This improves operational reliability.

[0022] A possible variant of the invention may be that an adjustment mechanism is provided between the fixing side and the light element, by means of which the position of the light element relative to the fixing side and / or the cone axis of the light cone and / or the position of the lamp housing can be changed, wherein preferably provision is made for the adjustment mechanism to have a pivot bearing and / or a thrust bearing. In this way, the user can influence the light path of the light element and adapt it to his needs.

[0023] The object of the present invention is also achieved by a handheld circular saw having a light emitting module according to any one of technical solutions 1 to 13.

[0024] Particularly preferably, the hand-held circular saw may have a saw blade holder for fixing the saw blade, the saw blade holder being rotatable about a drive axis by means of a drive assembly, wherein a protective cover is provided, the protective cover enclosing a chip guide space, a saw blade accommodating area being formed in the chip guide space, the saw blade accommodating area being arranged and constructed to accommodate the saw blade in the working position, wherein the protective cover has a side outer wall, the side outer wall delimiting the chip guide space on a side facing away from the drive assembly, wherein a light-emitting module is fixed on an outer side of the side outer wall facing away from the saw blade accommodating area by means of its fixing section, wherein the light-emitting module at least partially illuminates a cutting area of ​​the hand-held circular saw, and wherein the light-emitting element is preferably arranged behind the saw blade accommodating area along the feed direction of the hand-held circular saw.

[0025] In this case, it is also provided according to a variant of the invention that the light-emitting module is arranged and oriented so that the light emitted by the light-emitting element is mainly emitted along the feed direction of the hand-held circular saw, and the light emitted by the light-emitting 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, thereby achieving not only a simple structural form but also reliable and glare-free illumination of the cutting area.

[0032] Figure 5a Shown according to Figure 5 Schematic diagram of the installed state. DETAILED DESCRIPTION

[0033] Figure 1 A typical working situation is shown in which an operator P uses a hand-held circular saw 10 to process a workpiece 45 located on a workbench 44. The hand-held 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 hand-held circular saw 10 is placed on the rail upper side 41 of the guide rail 40. The hand-held circular saw 10 can be guided in a known manner on a guide element 43 of the rail 40 in the longitudinal direction of the rail.

[0034] According to the present invention, a lighting module 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 means of the lighting module.

[0035] Figure 2 and Figure 3 The technical solution 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 downwardly pointing support side 12, which cooperates with a guide element 43 of the guide rail 40 for longitudinal guidance. The guide plate 11 has a retaining structure in the region of its upper side 13, by means of which a drive assembly 20 can be connected to the guide plate 11.

[0036] The drive assembly 20 has a drive motor 21, through which the saw blade support 33 can be rotated. The saw blade 30 is fixed on 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 the 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.

[0037] 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 vertical axis according to the embodiment of the present invention. 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.

[0038] The protective cover 24 can have a connecting pipe 22.1, which is preferably connected in one piece to the protective cover 24. The connecting pipe 22.1 serves as a suction connection 22. A coupling 22.2 can be detachably fixed to the suction connection 22 by means of a locking element 22.3. The coupling 22.2 can be part of a suction hose of a chip suction device or a coupling for such a suction hose. During the machining application, the chips are sucked away from the chip guide channel 25 surrounded by the protective cover 24 via the chip suction device, which is spatially connected to the chip guide space 24.11.

[0039] 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.

[0040] The lateral outer wall 24 . 6 extends essentially perpendicularly to the drive axis 34 .

[0041] 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.

[0042] Figure 2 It is also shown that the side outer wall 24.6 carries two markings, namely a rear area marking 24.1 and a front area marking 24.2. Between the two area markings 24.1 and 24.2, the cutting area of ​​the saw blade 30 is marked visibly for the user P. The two area markings 24.1 and 24.2 thus show the rear saw blade boundary and the front saw blade boundary in the maximum insertion position of the saw blade 30.

[0043] like Figure 4As shown, in the front cutting area of ​​the saw blade 30, there is a recess 24.3 in the side outer wall 24.6, through which the front cutting area of ​​the saw blade 30 can be seen. The recess 24.3 can be covered by a removable and transparent window 24.4. The window 24.4 can carry a front area marking 24.2.

[0044] Figure 4 It is also shown that the protective cover 24 can have an upper covering area 24 . 5 which forms the above-mentioned chip guide channel 25 .

[0045] Figure 2 and Figure 3 Also show that the drive assembly 20 is connected to the guide plate 11 to realize the bevel cutting in a swingable manner. For this reason, the drive assembly 20 is connected to the guide plate 11 by means of a rear bevel bearing 26 and a front bevel bearing 27.

[0046] The rear bevel bearing 26 has a stationary bearing part 26.1 which is connected to the guide plate 11. A movable bearing part 26.2 is connected to the stationary bearing part 26.1 by means of a pivot bearing, wherein the movable bearing part 26.2 is coupled to the drive assembly 20.

[0047] The front bevel bearing 27 is constructed in the same manner and has a stationary 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.

[0048] The arrangement and guidance of the hand-held 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.

[0049] Figure 5 and Figure 5a It is shown that the lighting module 70 can be connected to the hand-held circular saw 10 in a replaceable manner.

[0050] The light emitting module 70 includes a light emitting element 71 , which is mounted in a lamp housing 75 .

[0051] The light module 70 can be replaceably connected to the hand-held circular saw 10. The light module 70 can be fixed using a connecting assembly.

[0052] As can be seen from the figure, the lighting module 70 is arranged behind the saw blade 30 in the feeding direction of the hand-held circular saw 10. The light emitted by the lighting module 70 is guided substantially in the feeding direction V, so that the light at least partially illuminates the sawing area between the two area markings 24.1 and 24.2. In particular, the lighting module 70 is sufficient to illuminate the area around the front area marking 24.2.

[0053] Figure 4A section is shown perpendicularly to the support side 12 of the guide plate 11 through the protective cover 24 and through the drive axis 34 .

[0054] As shown in the figure, different luminous areas L1, L2, L3 are formed according to the arrangement of the luminous module 70 relative to the side outer wall 24.6. The luminous areas L1 and L2 form particularly suitable luminous areas. The luminous area L1 is bounded by the side outer wall 24.6 and the surface of the workpiece 45 to be processed. The luminous 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 side outer wall 24.6 or to the outer side 32 of the saw blade.

[0055] The light emitting area L3 is not suitable because it does not illuminate the workpiece surface.

[0056] By following Figure 5 and Figure 5a In an embodiment, the light emitting areas L1 and L2 may preferably be at least partially illuminated.

[0057] As shown, the lighting module 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 module 70 has a fixing section 76 which can be replaceably connected to the protective cover 24.

[0058] The lighting module 70 has a lamp housing 75 in which a lighting element 71 is installed. A power supply device, in particular a battery, may also be arranged in the lamp housing 75 to supply power to the lighting element 71 .

[0059] The lamp housing 75 has a contact surface 72 in the region of the fixing side, which is arranged and designed to contact the outer side of the lateral outer wall 24.6. In the region of the contact surface 72, there can be a positive connection element 73, which contacts the mating positive connection element of the protective cover 24 in order to prevent the lamp housing 75 from moving in a plane parallel to the contact surface 72 and thus in the direction of the outer side of the lateral outer wall 24.6. The positive connection element 73 can be designed as a recess that engages in the contact surface 72. The mating positive connection element can be formed by a protrusion that protrudes onto the outer side of the lateral outer wall 24.6.

[0060] The connection between the light emitting module 70 and the protective cover 24 may be magnetically connected. For example, the lamp housing 75 may have a magnet 74 (or a ferromagnetic iron component) that cooperates with the ferromagnetic iron component (or magnet) of the protective cover 24 to form a magnetic connection.

[0061] In the present embodiment, the iron component (or magnet 74) is mounted on the outside of the side outer wall 24.6 and preferably also forms a matching 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 side outer wall 24.6 or arranged on the inner side of the side outer wall 24.6 facing away from the outer side of the side outer wall 24.6.

[0062] 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.

[0063] Preferably, in the installed state of the light module 70, the lamp housing 75 carries the light element 71 at its end facing the guide plate 11. Particularly preferably, the lamp housing 75 holds the light element 71 in the region of the boundary surface 24.8 and can thus also at least partially illuminate the light-emitting region L2, as shown in FIG. 7a by the light guide region 24.13 symbolically shown here.

[0064] The figure also shows that it is advantageous to arrange the switch 77 on the upper side of the light housing 75 facing away from the guide plate 11 , since the user P can activate the light-emitting element 71 away from the cutting area.

[0065] Figure 5 A shows that the fixing side of the fixing section 76 of the lamp housing 75 extends between the upper side of the housing and the lower side of the housing. The emission area of ​​the light emitting element 71 is arranged in the area of ​​the lower side of the housing and is preferably arranged to be spaced less than 30 mm from the lower side in the direction of the upper side of the lamp housing 75, so that it can illuminate near the workpiece.

[0066] The light emitting module 70 generates Figure 5a The light cone schematically shown in FIG. The cone axis of the light cone forms a main optical axis 78, which extends in the direction of the fixed side, preferably in a direction parallel to the fixed side. Particularly preferably, the main optical axis 78 runs along the feed direction V or substantially along the feed direction V.

[0067] As shown, it is advantageous if the light module 70 projects as little as possible on the lateral outer wall 24.6, so that the light module has a structural depth of as little as possible <40 mm in a direction perpendicular to the contact surface 72. The longest extension of the light module 70 extends perpendicular to the workpiece surface, so that the switch 77 is arranged as far as possible from the cutting area of ​​the saw blade 30.

[0068] The drawings also show that the lighting module 70 is designed so that the fixing side (especially the contact surface 72 ), the light emission direction (especially the cone axis of the light cone generated by the light module 70 ) and the longest dimension of the lamp housing 75 extend perpendicularly to each other.

[0069] In the above-mentioned variant of the invention, the lighting module 70 is arranged and oriented so that the light emitted by the lighting element 71 is emitted mostly in the feed direction V of the hand-held circular saw 10. The light emitted by the lighting element 71 extends at least partially, preferably completely, in the light guide area 24.13, which is separated from the dust-guiding area of ​​the chip guide space 24.11. The lighting module 70 holds the lighting element 71 behind the saw blade receiving area 24.12, as viewed in the feed direction.
