Description

[0001] The invention relates to an arrangement comprising a face shield and an object-holding device. Furthermore, the invention relates to a head shield comprising at least one such arrangement.

[0002] Helmets with visors to protect the wearer and object-holding devices for holding various objects are generally known from the state of the art. However, the use or wearing of such helmets is often not user-friendly or comfortable.

[0003] The datasheet "3M Face and Hearing Protection Combination G500", 2014, reveals a face and hearing protection combination.

[0004] From DE 10 2020 209 772 A1 a helmet adapter for half masks or respiratory masks and a helmet are known.

[0005] From DE 20 2020 102 624 U1 a helmet is known which has an adapter for attaching an accessory, such as a helmet lamp.

[0006] A device mounting device for a helmet, according to the preamble of claim 1, is known from US 2015 / 223540 A1.

[0007] The invention aims to overcome the disadvantages associated with the prior art. In particular, it seeks to provide an arrangement that is especially user-friendly and extremely comfortable. Appropriate head protection is also to be supplied.

[0008] This problem is solved according to the invention by the features specified in main claims 1 and 12. The core of the invention lies in the independent adjustability of the face shield and the object-holding device relative to each other. For example, only the face shield is adjustable, which leaves the position or orientation of the object-holding device, in particular its set position, unaffected. Conversely, for example, only the object-holding device is adjustable, which leaves the position or orientation of the face shield, in particular its set position, unaffected. The face shield and the object-holding device are uncoupled with respect to adjustment. The arrangement is mounted directly or indirectly on the assembled head-guard body.

[0009] The design, whereby the object-holding device as a whole can be pivoted about the first axis, is extremely user-friendly. The object-holding device is thus particularly easy and precisely adjustable (guided). When the device or head protection is worn as intended, the first axis preferably extends (essentially) horizontally.

[0010] The design in which the first axis coincides with the face shield adjustment axis is again very user-friendly. Preferably, the first axis and the face shield adjustment axis each form a pivot axis.

[0011] The face shield is preferably symmetrical and, when worn, capable of protecting at least part of the wearer's face, particularly at least their eyes, from hazards such as mechanical impacts, light (sun), wind, or the like. It may be designed, for example, as a visor, shield, protective screen, visor, goggles, mesh element, or the like. It is advantageous if the face shield is adjustable between a (lower) protective / wearing position and an (upper) storage position. In the protective position, the face shield is preferably located (essentially) at least partially below the head protection base. The wearer is then preferably able to see through the face shield. In the storage position, the face shield advantageously covers at least part of the head protection base and thus does not interfere with the wearer's vision.It is advantageous if the face shield has at least one viewing area and preferably at least one lateral storage area, preferably two lateral storage areas.

[0012] The head protection body is preferably designed as a head protection shell or dome. It is preferably symmetrical and, when worn, capable of protecting at least part of the wearer's head from mechanical impacts, particularly from shocks, blows, or the like. For example, the head protection body is shock-absorbing. It may be padded on the inside or have a soft lining. Alternatively, the head protection body may be designed as a hard shell and be unpadded.

[0013] Preferably, a chin strap assembly is arranged on the head protection base body for locally fixing the head protection base body to the wearer's head.

[0014] Head protection comes in various forms, such as helmets, caps, hats, hoods, or similar items. It is primarily used in work, leisure, or sports settings.

[0015] The face shield retainer is capable of holding the face shield in a preset position. It may be, for example, integrally connected to the head guard body. Alternatively, the face shield retainer may be a separate component from the head guard body.

[0016] The object holding device is preferably designed as an object receiving device. It is capable of holding an object, such as a lamp, light fixture, camera, signaling device, communication device such as a loudspeaker, microphone, or the like, for example, by positive locking and / or friction locking, preferably releasably. It is adjustable and thus adaptable, for example, to the respective support or the prevailing situation.

[0017] The coupling device is directly or indirectly coupled to the head protection base when the assembly is mounted. It is in direct or indirect communication with the object holding device. It is advantageous if the object holding device is detachably attached to the head protection base.

[0018] Further advantageous embodiments of the invention are specified in the dependent claims.

[0019] The embodiment according to dependent claim 2 is particularly user-friendly. The face shield and the object holding device are each adjustable, particularly manually, with detents. To adjust the face shield or the object holding device from their respective detent positions, a corresponding detent force must be overcome. This makes unintended adjustment of the face shield or the object holding device more difficult or even impossible.

[0020] The object holding device according to dependent claim 3 is preferably adjustable incrementally or in steps. It is advantageously spatially unlimited or pivotable through 360°.

[0021] The at least one first locking element according to dependent claim 4 is, for example, configured as a tooth, head, knob, projection, or the like. The at least one first locking element is preferably configured as a depression, valley, or the like. They are preferably (essentially) complementary to each other. It is advantageous if a plurality of first locking elements are present. The first locking elements are then advantageously arranged along a circle or arc. Alternatively, a reversed arrangement of the at least one first locking element and locking element is possible.

[0022] The embodiment according to dependent claim 5 is also extremely user-friendly. The second axis preferably runs differently from the first axis. It advantageously extends perpendicularly or obliquely to the first axis. For example, the second axis runs (essentially) in a vertical plane when the device or head protection is worn as intended. Adjustment or pivoting about the first and second axes is preferably possible independently of each other. The object-holding device or object-holding assembly is thus particularly well adaptable to the respective wearer or the prevailing situation.

[0023] The embodiment according to dependent claim 6 also prevents or hinders unwanted adjustment of the object holding device relative to the coupling device. A detent force must be overcome for adjustment, particularly manually. The object holding device can be pivoted in steps or incrementally. It is preferably pivotable about the second axis within a spatially limited range.

[0024] It is advantageous if, according to subclaim 7, the at least one second locking element is configured as a valley, depression, or the like. The at least one second locking element is preferably configured as a tooth, head, knob, projection, or the like. They are preferably (essentially) complementary to each other. It is advantageous if a plurality of second locking elements are present. The second locking elements are preferably arranged at least along a partial circle or arc. Alternatively, a reversed arrangement of the at least one second locking element and locking element is possible.

[0025] The arrangement according to subclaim 8 is particularly reliable.

[0026] The arrangement according to dependent claim 9 is also very user-friendly. The face shield is safely adjustable, particularly manually, in increments or steps. Adjustment requires overcoming a corresponding detent force, which makes unintended adjustment of the face shield difficult or impossible.

[0027] The at least one third locking means according to dependent claim 10 is preferably configured as a pin, bolt, projection, or the like. It is advantageous if the at least one third locking countermeasure is configured as a depression, valley, or the like. They are preferably (essentially) complementary to one another. It is expedient if a plurality of third locking countermeasures are present. The third locking countermeasures are preferably arranged along a partial circle or arc. Alternatively, a reversed arrangement of the at least one third locking means and locking countermeasure is possible.

[0028] The embodiment according to dependent claim 11 is particularly practical. The face shield is easy to mount and dismount. It is replaceable, especially without tools. The retaining element is preferably displaceable against a spring force or restoring force, and more preferably slidable.

[0029] The head protection according to dependent claim 13 is very user-friendly and reliable. This design is space-saving and requires only a small installation space.

[0030] A preferred embodiment of the invention is described below by way of example with reference to the accompanying drawing. The drawing shows: Fig. 1 a perspective view of a head guard with an arrangement according to the invention, Fig. 2 an exploded view of the in Fig. 1 illustrated head protection, Fig. 3 a partial view of the in Fig. 1 , 2The head protection shown, which primarily depicts the face shield in a storage position, Fig. 4, essentially the one shown in Fig. 3 The view shown, with the face shield in its protective position, Fig. 5 essentially a longitudinal section through the arrangement shown, Fig. 6 an enlarged perspective view illustrating the object-holding device and part of the coupling device of the arrangement shown, and Fig. 7 a partial view of the arrangement, showing mainly first locking means and locking counter-measures of the arrangement.

[0031] One in the Fig. 1 , 2 The head protection shown in its entirety comprises a shell-like helmet shell 1 and a visor 2, which can be pivoted relative to the helmet shell 1 about a visor pivot axis 3.

[0032] The helmet shell 1 is rigid. It serves to cover at least part of the wearer's head (not shown). It is preferably symmetrical.

[0033] A visor retaining device 4, for example by means of detents, in particular detents, is arranged on each side of the helmet shell 1. The visor retaining devices 4 are arranged opposite each other and are, for example, structurally identical.

[0034] Each visor retaining device 4 has a one-piece main body 5. Each main body 5 is elongated and, when mounted, extends adjacent to a lower lateral edge of the helmet shell 1.

[0035] Each main body 5 carries a locking arc body 6 at its front, with several locking recesses 7 arranged along the locking arc body 6. The locking recesses 7 are identical in design. They face forward or downward and are open.

[0036] The visor 2 is made of plastic and is preferably manufactured in one piece. It is preferably transparent and may be tinted. The visor 2 has a pin-like or bolt-shaped visor locking projection 8 on each side on the inside. Each visor locking projection 8 has a circular outer contour in cross-section. The outer contour is (essentially) complementary to the locking recesses 7. When the head protection is assembled or mounted, the visor locking projections 8 engage with a locking recess 7 of the visor holding devices 4, thereby holding the visor 2 in a releasably detented position.

[0037] To form the sight pivot axis 3, the sight 2 carries a hollow cylinder body 9 on each side and inside. Each hollow cylinder body 9 has a base 10 and a free head 11 with an insertion ramp. Each hollow cylinder body 9 is tapered on its outer or circumferential side between the base 10 and the head 11, forming a locking device.

[0038] Each main body 5 has a bearing receptacle 12 adjacent to its locking arc body 6. Each bearing receptacle 12 is open laterally outwards and upwards.

[0039] Each visor holding device 4 comprises a retaining body 13, preferably plate-shaped, which is slidably guided in the respective bearing receptacle 12. Each retaining body 13 has an actuating button 14 at its top, which, in the home position of the respective retaining body 13, extends upwards through the adjacent main body 5.

[0040] Between each retaining body 13 and the adjacent main body 5, at least one return spring assembly 15, for example in the form of a coil spring, is arranged. Each return spring assembly 15 is supported on its bottom side against the associated main body 5 and is located below the corresponding retaining body 13. Each main body 5 has two boundary walls adjacent to the corresponding return spring assembly 15 in order to prevent, for example, lateral deflection of the assembly.

[0041] Each retaining element 13 has a central connecting projection 16 at its bottom, which engages the adjacent return spring assembly 15 from above. It also has a continuous circular retaining opening 17 between the actuating button 14 and the connecting element 16, which is completely closed on its circumference.

[0042] Each visor holding device 4 includes, in the area of ​​its bearing receptacle 12, a cylindrical bearing pin 18 projecting laterally outwards.

[0043] Furthermore, each sight-holding device 4 has a locking element 19 which, in its closed position, covers the adjacent bearing pin 18, the return spring assembly 15, and the return element 13 on the outside. Each locking element 19 can be positively locked and / or frictionally locked to the associated main body 5. For example, it is slidably guided on the associated main body 5.

[0044] When the sight 2 is mounted, each side section of the sight covers a locking element 19 on the outside. The respective hollow cylinder body 9 extends laterally through the adjacent locking element 19 and the retaining opening 17 of the retaining element 13. The adjacent bearing pin 18 engages the hollow cylinder body 9 from the inside. The at least one return spring 15 pushes the return element 13 upwards, so that it engages in the tapered section of the hollow cylinder body 9 between its base 10 and head 11, i.e., in its locking mechanism, particularly from below. This axially fixes the hollow cylinder body 9 relative to the corresponding sight retaining element 4 while still allowing it to pivot there. The sight 2 is thus held on the corresponding sight retaining element 4.

[0045] When the sight 2 is pivoted about the sight pivot axis 3, the sight detent projections 8 slide over the successively arranged detent recesses 7. This overcomes detent forces that hold the sight 2 in the corresponding detent positions. The hollow cylinder bodies 9 are pivoted relative to the retaining bodies 13 and the bearing pins 18.

[0046] To release the visor 2 from the visor retaining devices 4, the actuating buttons 14 are manually pressed downwards from their initial or retained position. This causes the retaining elements 13 to be moved downwards under compression by the return spring devices 15. The retaining elements 13 thus disengage from the hollow cylinder bodies 9, allowing them to be freely and axially guided outwards from the visor retaining devices 4. If no corresponding pressure is applied to the actuating buttons 14, the return spring devices 15 push the retaining elements 13 back upwards from the release position into their retained position.

[0047] The head protection also includes an object holding device 20, which is arranged laterally on the helmet shell 1. The object holding device 20 is adjustable and capable of holding an object (not shown), such as a lamp.

[0048] The object holding device 20 has a coupling device 21 and an object holding device 22.

[0049] The coupling device 21 is formed in one piece and has a cylindrical bearing base 23 which is hollow at least adjacent to its free end. The bearing base 23 has at least one longitudinal slot that allows the outer diameter of the bearing base 23 to be changed for assembly / disassembly. It also includes at least one outer detent projection adjacent to its free end.

[0050] Adjacent to the bearing base 23, the coupling device 21 has an outer stop body 24 which forms a ring projection.

[0051] The coupling device 21 also has two parallel and spaced-apart bearing arms 25, which project axially outwards relative to the stop body 24. The stop body 24 is arranged between the bearing arms 25 and the bearing base 23.

[0052] At least the main body 5, which is arranged adjacent to the object holding device 20, has a plurality of bearing foot detent recesses 26 on the outside of its bearing pin 18 ( Fig. 7 The bearing pin 18 has two locking projections 27 on its inner side, which are arranged opposite each other and spring inwards towards each other. A different number of locking projections 27 is possible.

[0053] When the bearing foot 23 is axially inserted from the outside laterally into the corresponding hollow cylinder body 9 for assembly, the bearing foot 23 is compressed.

[0054] In its assembled state, the bearing base 23 extends through the adjacent hollow cylinder body 9 and engages it in a detent-like manner. It extends through the sight 2 and engages the sight holding device 4 with the hollow cylinder body 9. The stop body 24 rests against the sight 2 on the outside, adjacent to the corresponding hollow cylinder body 9. The object holding device 22 is thus arranged on the outside of the sight 2. The bearing pin 18 engages axially in the bearing base 23. The detent projections 27 engage laterally in the detent recesses 26 of the bearing base. The object holding device 20 can thus be pivoted in its entirety about the sight pivot axis 3 in a detent-like manner. When pivoted accordingly, the object holding device 20 is pivoted relative to the adjacent sight holding device 4 and the sight 2. The detent projections 27 slide over the bearing foot detent recesses 26 and engage in a detent-like manner.A corresponding detent force must be overcome to swivel the device.

[0055] To release the bearing foot 23 from the hollow cylinder body 9, the detent force is overcome by the detent projection that engages behind the hollow cylinder body 9.

[0056] The object holding device 22 is designed as a hollow body. It is preferably made in one piece and, for example, is clamp-like. An object to be held can be detachably inserted into the object holding device 22 and fixed in place there.

[0057] The object-holding device 22 is pivotally mounted on the bearing arms 25. Each bearing arm 25 has an outer bearing head 28. The bearing heads 28 are arranged facing away from each other on the bearing arms 25. They are aligned with each other and form a (second) pivot axis 29. At least adjacent to a bearing head 28, a plurality of bearing arm detent recesses 30 are arranged on the outside of the corresponding bearing arm 25 on an arc line bounded at its ends around the pivot axis 29. The bearing arm detent recesses 30 face outwards. The object-holding device 22 has at least one detent projection 31 on its inner side adjacent to the bearing arm detent recesses 30, which engages with each bearing arm detent recess 30.

[0058] When the object holding device 22 pivots relative to the bearing arms 25 about the pivot axis 29, the detent projection 31 slides over the bearing arm detent recesses 30, overcoming a corresponding detent force.

[0059] The pivoting of the object holding device 22 about the pivot axis 29 is possible independently of the pivoting of the object holding device 20 about the sight pivot axis 3. Furthermore, the pivoting movements of the entire object holding device 20 and the object holding device 22 can be carried out independently of the pivoting of the sight 2.

[0060] When only the sight 2 is adjusted, the object holding device 20 or object holding device 22 remains stationary. It does not move with it.

[0061] The bearing foot detent recesses 26 form the first detent means, while the detent projections 27 form the first detent means. The bearing arm detent recesses 30 form the second detent means, while the at least one detent projection 31 forms a second detent means. The sight detent projections 8 form the third detent means, while the detent recesses 7 form the third detent means.

[0062] The terms "front", "back", "bottom", "top", "inside", "outside" or the like used here refer to the arrangement of the head protection when worn as intended.
