Description

Technical field of the invention

• eine schalenförmige Kalotte mit einem Befestigungssystem, und
• ein Element für den Augenschutz, das in Verwendungsposition vor dem Gesicht des Benutzers zur Bildung der (Augenschutz-)Maske platziert ist.

The invention relates to a helmet and eye mask unit comprising:

• a bowl-shaped dome with a fastening system, and
• an eye protection element placed in use position in front of the user's face to form the (eye protection) mask.

State of the art

From the WO 2005/070359 A1 is a generic unit of helmet and eye mask known. The eye mask is locatable to the helmet in front of the user's face. For this, the eye mask is adapted in shape to a corresponding opening of the helmet. The operation of the eye mask is often not very user-friendly.

From the US 2006/268220 A1 is a unit of helmet and an eye protection element known.

The US Pat. No. 6,174,058 B1 discloses an assembly of a cap and a connectable with this eye protection glasses.

From the post-published EP 2 425 729 A1 An arrangement is known which comprises a helmet and an eye protection element. Helmet and eye protection element are magnetically connectable.

It is known that a helmet is combined with a pair of glasses to protect the head and eyes in certain outdoor sports activities or in industry and construction. For optimal protection, it is crucial to achieve perfect contact between the helmet and the eye protection element.

A first known type of helmet is provided with a transparent visor, which is pivotally mounted on the front of the helmet. Such a visor is part of the helmet and can be moved with a simple hand movement of the wearer between an active use position and an inactive position out of the field of view. In the use position, the distance between the visor and the face is not adjustable and the visor must have a shape that conforms to the rounded profile of the hood front. In the case of a visible visor on the front of the helmet, which is in the inactive position, the visor remains exposed to influences and scratches, resulting in premature wear and thus a poorer visibility. In addition, the presence of a visible visor prohibits the wearing of an additional shield on the helmet. Such a generic helmet is for example from the DE 29 18 587 A1 known.

There are also helmets with integrated folding visors, which can be retracted when not in use in a gap in the interior of the hood wall. The execution of such a helmet remains complicated and is associated with high production costs. From the DE 20 2011 101 138 U1 For example, such a helmet is known.

• die elastische Kraft übt im Allgemeinen einen großen Berührungsdruck auf das Gesicht aus, wodurch das Schwitzen zum Nachteil des Komforts gefördert wird,
• wenn der Benutzer das Augenschutzelement in die inaktive Stellung bringen möchte, die sich auf dem oberen, abgerundeten Teil der Haube befindet, kann das Augenschutzelement nach hinten rutschen und auf den Boden fallen und beschädigt werden,
• das Wiederanbringen des Augenschutzelements in der Gebrauchsposition erlaubt nicht immer, die vorherige bevorzugte Stellung zu finden, was ein zusätzliches Einstellen erfordert,
• das Sehfeld ist begrenzt und unzureichend,
• es wird unbedingt eine Befestigungsvorrichtung hinten am Helm benötigt.

A second known type of helmet has an eye protection element that is not integrated into the hood, but is a separate part. The DE 10 2004 005 757 A1 discloses, for example, such a known helmet-spectacle combination. The attachment of the eye protection element is effected by an elastic band which surrounds the rear part of the hood or the head of the user. The presence of this elastic band brings with it the following inconveniences:

• the elastic force generally applies a large contact pressure to the face, thereby promoting sweating to the detriment of comfort,
• if the user wishes to bring the eye protection element into the inactive position located on the upper, rounded part of the hood, the eye protection element may slip backwards and fall to the floor and be damaged,
• the replacement of the eye protection element in the use position does not always allow to find the previous preferred position, which requires an additional adjustment,
• the field of vision is limited and inadequate,
• It is absolutely necessary a fastening device behind the helmet.

Subject of the invention

The essence of the invention is to realize a whole of protective helmet and protective mask (= goggles), in which the eye protection element with a good contact surface to the face without excessive pressure can be quickly placed and easily removed again for stowing or cleaning.

The entirety of protective helmet and protective mask is characterized in that the upper edge or upper edge of the eye protection element conforms to the profile of the lower edge or lower edge of the Kalottenvorderteils and that a magnetic device disposed at the two edges for attaching the eye protection element to the calotte wherein the magnetic device comprises a first series of permanent magnets fixedly connected to one of the two edges and cooperating by magnetic attraction with corresponding elements of the opposite edge.

Thus, an effective grip of the glasses is achieved at the lower Kalottenkante and a good rejection of drafts and, in the case of tinted glasses, the sun's rays. The replacement of the classic rubber band for attachment by the magnetic connection device makes it possible to use larger glasses with a very wide field of view.

The contact pressure of the glasses on the face is less strong than that of a conventional glasses with elastic band, which provides more comfort and less sweating.

The front magnetic connection portion between the two respective edges includes means for tilting the glasses and for adjusting the attachment to the face. The tilting means are preferably located centrally in the front connection area and include detents and complementary notches for positioning the spectacles, thereby allowing adjustment movement about an inclination axis.

The eye protection element is preferably designed as glasses, visor, mask, visor or the like.

The term "first series" is preferably understood to mean a first arrangement.

By "complementary" elements are meant elements which are capable of interacting magnetically or interacting with the permanent magnets as counter-elements.

The complementary magnetic elements may be formed either of ferromagnetic parts or of a second series of permanent magnets with the magnets of the first series of opposite polarity.

The term "second series" is preferably understood to mean a second arrangement.

By "complementary" notches are preferably understood notches that are capable of interacting with the detents.

According to another embodiment of the invention, the permanent magnets of the lower edge sit in notches with the insertion of an elastic spring system.

Flexible connection means are advantageously arranged between the helmet and the spectacles, in order to prevent the spectacles from being lost when not in use.

The embodiment according to claim 10 allows a particularly simple and good adaptation of the eye protection element to the head of the user. In addition, the insert according to claim 10 is preferably guided displaceably on the shell of the dome between a lower position and an upper position. It is preferably guided displaceably within the shell.

The at least one swivel joint according to claim 11 preferably has exactly one swivel joint lever. This swivel joint lever is hinged to the glasses, preferably on a fitting part of the glasses, and the dome. According to an alternative embodiment, the at least one swivel joint has two swivel joint levers, which in turn are connected to one another in an articulated manner. The one swivel joint lever is again articulated to the glasses, while the other swivel joint lever is articulated to the calotte.

The at least one face-pressing spring element according to claim 12 is preferably arranged between the glasses and the dome. Conveniently, the at least one face-pressing spring element is designed as a helical spring, coil spring, torsion bar or the like.

The embodiment according to claim 13 allows a particularly safe and easy pivoting of the glasses. The glasses are so extremely good and easily adaptable to the user's face. It is advantageous if the fitting part is pivotably mounted on the spectacle frame of the spectacles or the upper part of the actual spectacles. Alternatively, the at least one face-pressing spring element between the adjusting part of the glasses and the remaining part of the glasses is arranged.

It is advantageous if the fitting part in its use position is additionally fixable in a form-fitting manner by first and second form-fitting parts on the calotte.

The pairwise cooperating first and second form-closure parts are expediently designed in such a way that removal of the fitting part from the calotte downwards in the direction of the upper part of the spectacle frame or the spectacles is prevented during their engagement. It is advantageous if the adjustment part is only removable by pivoting forward of the calotte.

It is advantageous if the fitting part is removable from both the spectacle frame or the upper part of the actual glasses and the calotte.

Detailed description of the invention

In the figures, a unit of helmet and protective mask (= protective goggles) designated by the numeral 10 is constituted by a cup-shaped dome 11 which is adapted to surround the head of the user and by an eye protection element 12 which is determined in front of the face to be placed to protect eyes from wind, moisture, cold and sun rays.

The dome 11 is formed by a rigid shell made of impact-resistant plastic, in particular of thermoplastic material of the types ABS, PC, PVC or PET, and a lower shell of shock-absorbing material of the EPS, EPP ... type. The calotte 11 is equipped with a conventional fastening system 13 equipped with chin strap 13a and buckle (not shown).

The eye protection element 12 of the spectacles consists in the figures of a transparent screen of low strength, tinted or untoned, covering the entire face at the level of the eyes. He may also have the profile of a pair of glasses (not shown) with a pair of umbrellas or glasses in front of his eyes. The transparent material of the eye protection element 12 has a high impact resistance and is preferably unbreakable.

The eye protection element 12 of the spectacles is fastened in the position of use by means of a magnet device 14 with a permanent magnet 15 on the helmet ( Fig. 2 ).

Flexible connection means 16 allow the connection of the glasses to the cap 11 to make them captive when the glasses are no longer in the use position on the helmet. These connecting means 16 may consist of a cord 17, one end of which is fastened to the spectacle base and the opposite end of which cooperates with a reel 18 in the interior of the calotte 11, in particular in a region near the user's ear. Of course, any other retaining band, for example made of elastic or inelastic material with or without reel, can be used.

In Fig. 2 the magnetic device 14 consists of a first row / series of permanent magnets 15, which are arranged along the lower edge 19 on the front side of the dome 11 spaced from each other and by magnetic Attraction cooperate with complementary elements 20 at the upper edge 21 of the eye protection element 12.

• nämlich als ferromagnetische Teile, die vom Magnetfeld der Dauermagneten 15 bei einer Annäherungsbewegung der Brille in Richtung auf die Unterkante 19 der Kalotte 11 angezogen werden. Es ist auch möglich, die Anordnung der Dauermagnete 15 und der komplementären Elemente 20 auf den Kanten 19 und 21 umzukehren.
• nämlich durch eine zweite Reihe/Serie von Dauermagneten, deren Polung denjenigen der ersten Reihe entgegengesetzt ist, so dass der Effekt der magnetischen Anziehung und der Zentrierung durch die gegensätzlichen Pole verstärkt ist.

These complementary elements 20 can be made as follows:

• namely as ferromagnetic parts, which are attracted to the magnetic field of the permanent magnet 15 in an approaching movement of the glasses in the direction of the lower edge 19 of the cap 11. It is also possible to reverse the arrangement of the permanent magnets 15 and the complementary elements 20 on the edges 19 and 21.
• namely, by a second row / series of permanent magnets whose polarity is opposite to that of the first row, so that the effect of magnetic attraction and centering is enhanced by the opposite poles.

The pole faces of the permanent magnets 15 and the contact surfaces of the complementary elements 20 with which they come into contact are preferably planar in order to achieve an optimal attraction effect.

The upper edge 21 of the eye protection element 12 conforms exactly to the shape of the lower edge 19 of the helmet front part, in order to avoid any gap in the magnetic connection region. Thus, an effective grip of the glasses is achieved at the lower edge 19 of the cap 11 and a good rejection of drafts and, in the case of tinted glasses, the sun's rays.

In the execution, as in the Figures 3 and 4 4, the front magnetic connection portion between the two respective edges 19 and 21 of the helmet and the glasses is formed to additionally incline to allow the eye protection element 12 of the glasses according to arrow F. Thus, regardless of the shape of the user, an optimal adjustment of the contact with the face can be achieved.

The central region of the lower edge 19 has a concave or convex shape and has position pawls 22 for tilt adjustment of the spectacles about the inclination axis XX '. The upper edge 21 of the spectacles advantageously has notches 23 which cooperate with one of the notches 22 in a selected position of the inclination adjustment. A permanent magnet 15 may be inserted in this central area opposite to a complementary magnetic element 20. Two other lateral areas are located adjacent to the central area and have permanent magnets 15 and complementary magnetic elements 20 for holding the goggles in place by applying a light pressure to the face.

The peripheral inner wall of the glasses is also coated with a foam layer 24, which ensures a pleasant and tight contact with the face.

In the execution of Fig. 2 certain permanent magnets 15 are housed in the lateral areas in notches 25 of the helmet lower edge with the insertion of a spring 26 or other elastic system. The width of the tilt adjustment is increased while maintaining an equal pressure on the face.

The lack of a rubber band for attachment allows the use of larger glasses with a very wide field of view.

The glasses are put on and taken off as follows:

For placement, it is sufficient to approximate the eye protection element 12 of the lower edge 19 of the calotte 11. The magnetic attraction exerted by the permanent magnets 15 on the complementary magnetic elements 20 causes the glasses on the lower edge 19 comes to a stop. This results in a stable contact surface on the face with good protection of the eyes against wind, moisture, cold and -with a window tint - against sun rays. The wearing comfort can be further improved by the tilt adjustment of the glasses. The contact pressure is less severe than that of conventional rubber-banded goggles, which provides more comfort and less sweating.

To remove the glasses, one exerts a slight pivoting movement from bottom to top on the glasses, which causes a skewed separation of the complementary elements 20 of the permanent magnet 15. This results in an air gap in Diederform, which has a strong reduction of the magnetic attraction forces and a very rapid separation of the complementary elements 20 result.

• die Brille kann unverlierbar auf der Vorderseite des Oberkörpers baumeln,
• die Brille ist zu Reinigungszwecken leicht zugänglich,
• sie kann schützend unter der Jacke verstaut werden.

When the glasses are in a separated position ( Fig. 5 ), the existing cord 17 of the connecting means 16 allows the following:

• the glasses can dangle captive on the front of the upper body,
• the glasses are easily accessible for cleaning purposes,
• It can be stowed under the jacket to protect it.

The cord 17 can take two different lengths, a shortened length in the use position of the glasses and the other, full length when not in use (inactive position).

The following is with reference to the FIGS. 6 to 9 a further embodiment of the invention described. In contrast to the previous embodiment, the helmet-eyeglass unit comprises an adapter-like fitting part 27, which is designed like a bar or bow. The fitting part 27 is part of the eye protection element 12. It has an elongated shape and extends in the mounted state above an upper edge of the spectacle 28 of the actual spectacles or a spectacle frame of the spectacles. The upper edge 21 of the glasses runs on the fitting part 27.

The fitting part 27 has two opposite ends 29. At each end 29 at least one complementary element 20 is arranged on the fitting part 27. Alternatively, the complementary elements 20 are provided spaced from the ends 29 on the adapter 27. It is advantageous if the course of the fitting part 27 is substantially adapted to the corresponding course of the upper spectacle edge 28.

It is advantageous if the first form-fitting part 30 is arranged centrally between the complementary elements 20.

At the fitting part 27, two first pivot bearing parts 31 are further arranged. It is advantageous if the first pivot bearing parts 31 are provided between the complementary elements 20 and opposite to the first form-fitting part 30. According to the FIGS. 8 and 9 the first pivot bearing parts 31 are designed as bearing receptacles. Conveniently, the first pivot bearing parts 31 are arranged at the bottom of the fitting part 27.

At the upper edge of the spectacle 28 or at the top of the spectacle frame two second pivot bearing parts are provided (not shown). The second pivot bearing parts are formed complementary to the first pivot bearing parts 31. They are each formed by aligned pivot pins, which define the tilt axis XX 'and extend in the width direction of the glasses.

In the assembled state of the fitting part 27, the first and second pivot bearing parts 31 are each in pairs with each other in pivotal connection and together form respective pivot bearings. The glasses can be pivoted about the inclination axis XX 'forward and backward.

At the lower edge 19 on the front side of the calotte 11, a second, helm-sided form-fitting part 32 is arranged, which is designed to be complementary to the first form-fitting part 30. The second form-fitting part 32 is according to Fig. 8 designed as a pin and is disposed between the permanent magnet 15. It projects down from the lower edge 19.

If the permanent magnets 15 interact magnetically with the complementary elements 20, the first and second form-fitting parts 30, 32 are also positively connected with one another and thus provide for an additional fixation of the fitting part 27 on the calotte 11. The form-fitting elements 30, 32 are arranged and designed so that they can be automatically brought together with each other in the approach of the permanent magnets 15 and the complementary elements 20 into engagement.

The pairwise cooperating first and second form-fitting parts 30, 32 are designed such that removal of the fitting part 27 from the calotte 11 downwards in the direction of the upper part of the spectacle frame or of the spectacle rim 28 is prevented during their engagement. The fitting part 27 is removable only by pivoting forward of the dome 11. The first form-fitting part 30 is open to the rear. It is keyhole-shaped. On the second form-fitting part 32 is also an over at least a portion of its peripheral portion extending, outwardly open receiving groove 33 is arranged in the form-locking engagement of the first and second form-fitting parts 30, 32 engages a corresponding web of the first form-fitting part 30 form fit. It is advantageous if surmountable noses of the first form-fitting part 30 prevent unintentional pivoting out of the fitting part 27 from the second form-fitting part 32.

According to an alternative embodiment, the first and second form-fitting parts 30, 32 are arranged reversed. According to an alternative embodiment, the first and second pivot bearing parts 31 are arranged reversed.

Referring to Fig. 10 At least one face-pressing spring element 34 is arranged on at least one of the adjusting part pivot bearings. The at least one face-pressing spring element 34 is arranged on the at least one first and / or second pivot bearing part 31.

At the at least one first and / or second pivot bearing part 31 corresponding latching elements 34a and locking counter-elements 34b are arranged. Alternatively, the at least one first and / or second pivot bearing part 31 corresponding latching elements 34a and latching counter elements 34b assigned.

Referring to Fig. 12 For example, the calotte 11 includes an insert 35 which is slidably guided between an upper position and a lower position on the shell of the calotte 11. The insert member 35 is manually operable from the outside by a handle member 36. On the insert part 35, the permanent magnets 15 are arranged. The permanent magnets 15 are thus adjustable in height.

The complementary elements 20 are arranged on the glasses and cooperate with the height-adjustable permanent magnet 15. The complementary elements 20 may be arranged on the fitting part 27 or directly on the spectacle frame or the spectacle edge 28. Due to the height adjustment of the permanent magnets 15 and the glasses in height with respect to the calotte 11 is adjustable. The higher the permanent magnets 15 are arranged, the higher the glasses sit. The deeper the permanent magnets 15 are arranged, the deeper the glasses sit.

Referring to the FIGS. 13 to 15 is at the fitting part 27 at the end in each case a pivot lever 37 pivotally mounted. The swivel joint levers 37 are also pivotable on the spectacle frame stored. Alternatively, they are pivotally mounted on the glasses and the cap 11. The swivel joint levers 37 together with the associated articulation points form pivot joints. By the swivel joint lever 37, the glasses is guided by their use position in their upper storage position displaced. In the storage position, the actual goggles are spatially separated from their fitting part 27, which remains in magnetic connection with the lower edge 19 of the dome 11.

In Fig. 13 the glasses are in their position of use. It adjoins the dome 11 in the lower front and is fixed magnetically to the latter via the magnetic device 14. The swivel joint levers 37 are in a first position. When relocating the glasses from their use position in their upper storage position and the pivot lever 37 are pivoted. When pivoting in the storage position, the glasses are moved by the pivot lever 37 also forward. In the storage position, the glasses are outside on the front of the calotte 11. The rocker arms 37 then assume a second position. As mentioned above, instead of the glasses and a screen, visor, a mask or the like can be used.
