Description

head guard

The content of German patent application 10 2013 215 150.0 is hereby incorporated by reference.

technical field

The invention relates to a head guard, in particular for work protection. The invention also relates to a headgear arrangement comprising such a headgear.

Background technique

Head shields are known from the prior art, the rigid outer shell of which is equipped with padding elements on the inside, so that on the one hand the head shield can be worn comfortably and on the other hand it provides a very high protective effect against impacts . The filling element can be formed, for example, by a foam body, a sponge rubber body or a spacer fabric. A disadvantage of this known headgear is that it is very complicated to manufacture. Furthermore, the headgear no longer has sufficient protection capacity when the filling element is removed or lost.

DE 10 2007 028 759 A1 discloses a safety helmet having a helmet shell. The housing has an absorption channel in the top region, which is covered by a separate absorption structure. The absorption structure is formed by the absorber plate, the torsion sleeve on the absorber plate side and the rigid pin on the housing side. In the event of a force acting on the absorption structure from above, the torque sleeve is pushed axially onto the rigid pin, which causes it to twist. As a result, the torsion sleeve is deformed plastically and absorbs the impact energy. The manufacture of such known safety helmets is complicated.

A protective helmet with a spring system is known from DE 1 732 210 U. The protective helmet has an upper part and a lower part and an elastic middle part arranged between the upper part and the lower part. The middle part consists of flat irons interconnected by coil springs.

Contents of the invention

It is therefore the object of the present invention to provide a headgear which, on the one hand, can be produced very cost-effectively and, on the other hand, offers a very high protective effect for the wearer. Furthermore, the head guard should be able to be used particularly flexibly. A corresponding headgear arrangement should likewise be provided.

The headgear provided by the invention is used in particular for work protection, the headgear having a housing which: has a front forehead area for at least partially covering the forehead of the wearer of the headgear There is a rear region of the head for at least partially covering the rear of the head of the head shield wearer, wherein the region of the rear of the head faces away from the forehead region of the front; there is a forehead arranged at the front The top of the head region between the region and the back of the head region at the rear is used to at least partially cover the top of the head of the head shield wearer; and defines a head receiving cavity for receiving the head of the head shield wearer head. The core idea of the invention is that the head shield is provided with a damping structure comprising at least one damping spring device, which has: two connecting bodies arranged at a distance from each other and adjoining the housing , the connecting bodies each protrude outward from the housing; and at least one connecting web extending between two connecting bodies arranged in pairs in the form of a bridge. At least one connecting web is at least partially elastically displaceable for vibration damping. The connecting web is displaced when a corresponding external force acts on it, for example in the event of a collision or impact. It is advantageous if at least one connecting web is largely displaceable for vibration damping.

It is also advantageous if the at least one connecting web springs back into its rest position or initial position after an external impact force has acted. Preferably, the at least one connecting web itself is somewhat flexible or elastically yieldable, which improves the vibration-damping properties.

The at least one connecting web is preferably straight or curved outwards.

Advantageously, the head shield is designed symmetrically with respect to the plane of symmetry.

Advantageously, the housing also has a lateral side region for at least partially covering the side of the head of a wearer of the headgear.

The housing is preferably designed to be inflexible or inherently rigid. Advantageously, the housing is made of plastic material.

Suitably, the damping structure is fixedly connected to the housing.

Preferably, the head shield is insertable into a hat, in particular a peaked cap. Thereby, a head shield arrangement is provided comprising a hat and a head shield according to the invention inserted into said hat for reinforcing said hat. Expediently, the head shield can also be removed from the cap again. Unique adjustments are thus possible.

The one-piece design of housing and damping structure enables very simple and cost-effective production. Advantageously, the damping structure and the housing are produced in one piece from the same plastic material, for example by injection moulding. Alternatively, they are produced from different plastic materials, for example in a two-part injection molding process. Preferably, therefore, at least one connecting web, connecting body and housing are designed or injection molded in one piece. If present, at least one reinforcing element is also preferably designed in one piece with at least one connecting web. Preferably, the at least one reinforcing element is injection molded on the at least one connecting web.

Further advantageous embodiments of the invention are described below.

According to one configuration, the at least one damping spring device is in contact with the housing only via the connecting body. This refinement enables a headgear with a very high protective effect.

According to one refinement, the at least one damping spring device is at least mostly spaced outwardly from the housing. This design also provides a very high degree of protection for the wearer of the headgear. The at least one damping spring arrangement therefore has a particularly large maximum spring travel.

According to a preferred configuration of the damping structure, the damping structure extends in the overhead region of the housing. Alternatively or additionally, the damping structure is arranged in the front forehead region, the rear rear head region and/or the lateral side regions.

According to one refinement, the at least one damping spring arrangement is perpendicular to the direct connection line between the forehead area and the back of the head area. Alternatively, the at least one damping spring arrangement is inclined or parallel to a direct connecting line between the forehead area and the back of the head area.

According to a design solution, the at least one connecting web is hinged to the shell through a connecting body connected to the connecting web. This refinement enables a suitable deformation of the at least one damping spring arrangement in the event of external forces. Furthermore, a controlled deflection or displacement of the at least one connecting web can thus also be achieved via the at least one connecting body. Expediently, the external force is attenuated primarily by displacement of the at least one connecting web, by deflection of the at least one connecting body, and only secondarily by deformation of the at least one connecting web.

According to one configuration, each connector is designed to be stepped. This refinement also enables particularly targeted and controlled vibration damping.

This also applies to the following design scheme: each connection body (16) has a first connection part connected to the shell, a second connection part connected to the connection web, and a connection between the first connection part and the second connection part. The stepped portion between the connecting portions forms an inclination angle with the first connecting portion and the second connecting portion respectively, and the inclination angle is preferably between 60° and 120°. Suitably, both angles are the same. Preferably a right angle. Preferably, the first connecting portion and the second connecting portion of the connecting body are substantially parallel to each other.

According to one refinement, the housing is provided with recesses in the region of the at least one damping spring arrangement. This refinement also results in a particularly high spring travel of the at least one connecting web. Furthermore, this achieves a particularly high wearing comfort.

According to one design solution, the vibration damping structure also has at least one reinforcing element arranged adjacent to the at least one connecting web for strengthening the at least one connecting web, wherein preferably, the at least one reinforcing element Designed to strengthen the honeycomb body. The at least one reinforcement element achieves an increased protective effect for the wearer of the headgear. The at least one reinforcing honeycomb preferably opens towards the head receiving cavity. The reinforced honeycomb body may have a circular, oval, square or similar cross-section in cross-section. Combinations are also possible. Preferably, a plurality of reinforcing honeycomb bodies are provided on each connecting web. Instead of at least one reinforcing honeycomb body, at least one reinforcing rib, a reinforcing insert or the like is provided.

According to one refinement, the at least one reinforcing element is arranged below the connecting web to be reinforced and is preferably fixedly connected to this connecting web. The arrangement of the at least one reinforcing element enables a particularly visually attractive headgear. The at least one reinforcing element is thus arranged substantially invisible or concealed from the outside.

According to one refinement, a plurality of damping spring arrangements are provided, wherein preferably, the plurality of damping spring arrangements are parallel to each other. Advantageously, at least three, preferably at least five, more preferably at least ten damping spring arrangements are provided. Preferably, there are less than 30, preferably less than 20, more preferably less than 15 damping spring devices. Expediently, the damping spring arrangements are each arranged spaced apart from one another and have substantially the same distance from one another. Other arrangements are also possible.

According to a design solution, the housing and the vibration damping structure are designed as a one-piece plastic injection molded part. This refinement enables very simple and cost-effective production. It is advantageous if the damping structure and the housing are produced in one piece from the same plastic material, for example by injection moulding. Alternatively, they are produced from different plastic materials, for example in a two-part injection molding process. This preferably means that the at least one connecting web, connecting body and housing are designed or injection molded in one piece. If present, the at least one reinforcing element is also preferably designed in one piece with the at least one connecting web. Preferably, the at least one reinforcing element is injection molded on the at least one connecting web.

FIG. 7 shows a view from below showing the head shield shown in FIGS. 5 and 6 .

Detailed ways

The headgear arrangement in the unloaded normal state will first be described below. The head shield device generally includes an outer cap 1 and a head shield 2 inserted therein. The cap 1 is preferably made of a flexible material, such as a textile or fabric material, while the head shield 2 is basically designed to be inherently rigid and made of a plastic material. By means of the headshield 2 inserted into the cap 1, the safety of protecting the head of the headshield wearer from external mechanical influences is increased.

The cap 1 comprises a deformable cap shell 3 and a bill 4 connected to the cap shell at the front, which bill is preferably rigid to a certain extent. The cap shell 3 delimits a receiving cavity 5, while the visor 4 provides protection against light, in particular sunlight, or mechanical influences from above. The visor 4 may comprise at least one reinforcing element.

The head shield 2 is inserted into the receiving cavity 5 of the cap 1 from below. The head shield 2 is partially fixed in the receiving cavity 5 . For this purpose, at least one corresponding holder (not shown) is provided on the cap shell 3, such as a Velcro element, a hook, a button, a catch, a retaining strip, a receiving groove or the like. . Preferably, the head shield 2 is fixed partially by folding over a head strap (not shown) arranged on the peaked cap 1 .

The headshield 2 also includes a shell 6 which substantially matches the cap shell 3 in terms of size and shape. In the inserted state of the head shield 2 , the housing 6 is arranged next to the cap shell 3 . The housing 6 preferably rests at least partially on the inner side of the cap shell 3 .

The housing 6 has a front forehead region 7 , a rear occipital region 8 , a crown region 9 and two mutually opposite side regions 10 .

In the inserted state of the head shield 2 , the forehead region 7 is arranged adjacent to the bill 4 of the peaked cap 1 . The forehead region 7 is arranged adjacent to the head shield arrangement or the forehead of the wearer of the head shield if the head shield arrangement is worn correctly.

The crown region 9 directly adjoins the forehead region 7 . If the headgear arrangement is worn correctly, the crown region 9 covers the headgear arrangement or the top of the head of the wearer of the headgear.

The back of the head region 8 is connected to the rear of the top of the head region 9 . It is arranged substantially opposite the forehead area 7 . The back of the head region 8 at least partially covers the back of the head of the head shield arrangement or the wearer of the head shield if the head shield arrangement is worn correctly.

Extending laterally from (both sides of) the crown region 9 is a side region 10 in each case, which is thus arranged between the forehead region 7 and the back of the head region 8 . The side regions 10 are each formed by at least one segment 11 . In this embodiment, each side region 10 is essentially formed by two segment bodies 11 which are separated from each other by a separating notch 12 . Alternatively, other numbers of segment bodies 11 are also possible.

The head guard 2 is designed symmetrically with respect to a plane of symmetry 13 which extends centrally between the side regions 10 .

The housing 6 is designed in one piece. The forehead area 7 , the back of the head area 8 , the top of the head area 9 and the side areas 10 are thus connected to one another in one piece. The housing 6 defines a head receiving cavity 18 for receiving the head shield arrangement or the head of a wearer of the head shield.

The head shield 2 also has a damping structure 14 comprising a plurality of damping spring arrangements 15 . The damping spring devices 15 all have the same structural design. Their sizes may differ from each other.

Each damping spring arrangement 15 has two identical connecting bodies 16 , which adjoin the housing 6 in one piece and are arranged in pairs. In this case, the damping structure 14 is arranged substantially in the parietal region 9 . It also protrudes slightly into the forehead area 7 and into the back of the head area 8 . Alternatively, other arrangements are also possible.

Furthermore, each damping spring arrangement 15 has a connecting web 17 which extends bridge-like between the associated connecting bodies 16 . The connecting web 17 is of elongated and preferably spring-like design. The connecting web has essentially a constant width towards the forehead area 7 or the back of the head area 8 . The plane of symmetry 13 runs centrally through the damping spring arrangement 15 .

The connection body 16 protrudes outward from the housing 6 . The connectors are each designed stepwise. The connecting body 16 of the damping spring device 15 extends here from the housing 6 in a slightly converging manner. They each have a width in the direction of the forehead region 7 or the back of the head region 8 , which corresponds to the corresponding width of the corresponding connecting web 17 .

Each connecting body 16 has a first connecting portion 19 directly adjoining the housing 6 and a second connecting portion 20 directly adjoining the corresponding connecting web 17 . A stepped portion 21 is arranged between each first connection portion 19 and each connection portion 20 .

The connection body 16 of the damping spring arrangement 15 runs in the region of its first connection 19 from the housing 6 at a slight inclination or converges at an inclination to the plane of symmetry 13 . The first connection part 19 is designed as a plate.

The stepped portion 21 is designed as a plate. The stepped portion is connected on the inside to a corresponding first connecting portion 19 . The step 21 of the damping spring arrangement 15 extends obliquely from the first connection 19 in the direction of the plane of symmetry 13 . The stepped portions 21 are respectively designed to be shorter than the first connecting portion 19 and the second connecting portion 20 . The connecting body 16 protrudes obliquely in the direction of the symmetry plane 13 in the step 21 on the one hand, and protrudes inwards in the direction of the head receptacle 18 on the other hand.

The second connection part 20 is designed as a plate. The connection body 16 of the damping spring device 15 runs in the region of its second connection 20 starting from the step 21 at a slight inclination or converging at an inclination to the plane of symmetry 13 . The second connecting portion 20 is substantially displaced inwardly with respect to the first connecting portion 19 . An obtuse angle ws is provided between the second connecting portion 20 and the corresponding connecting web 17 .

The first connecting portion 19 and the second connecting portion 20 of the connecting body 16 are substantially parallel to each other. A substantially right angle wr1 is provided between the first connecting portion 19 and the adjacently arranged step portion 21 . A substantially right angle wr2 is provided between the stepped portion 21 and the adjacently arranged second connection portion 20 .

The connecting webs 17 are therefore shorter than the distance between the first connecting parts 19 of the damping spring arrangement 15 in the housing 6 .

Arranged on the inside of each connecting web 17 is a reinforcing honeycomb body 22 which is open in the direction of the head receptacle 18 and which is connected in one piece to the respective connecting web 17 . The reinforcing honeycomb bodies 22 are preferably arranged next to each other in rows and/or columns. They are preferably the same. In this embodiment, the reinforcing honeycomb body 22 has a hexagonal design and delimits an interior space 23 laterally outward.

The connection web 17 is substantially offset outwards relative to the housing 6 due to the connection body 16 .

Each damping spring device 15 is associated with a recess 24 provided in the housing 6 . The recess 24 is arranged substantially directly below the corresponding connection web 17 in the housing 6 . The recess 24 extends between the first connections 19 of the damping spring arrangement 15 . Advantageously, the recesses 24 are each slightly wider in the direction of the brow area 7 and the back of the head area 8 than the connection webs 17 . The individual recesses 24 are separated from each other by a transverse web 25 of the housing 6 . The transverse webs 25 are substantially parallel to each other and perpendicular to the direct connection line between the forehead area 7 and the back of the head area 8 . The course of the transverse web 25 approximately corresponds to the course of the adjacently arranged connecting web 17 . The transverse webs 25 and the adjacently arranged connecting webs 17 are for example curved to the same extent or straight. The transverse web 25 has a width in the direction of the brow region 7 and the back of the head region 8 which is smaller than the corresponding width of the adjacent connecting web 17 . Preferably, this width is approximately only half of the latter width.

The head shield 2 also has windows 26 which are spatially delimited on the inside by the transverse webs 25 , on the outside by the connecting webs 17 and laterally by the connection bodies 16 . The window 26 extends substantially perpendicularly outwards relative to the housing 6 . Very good ventilation can be achieved through the windows 26 and the recesses 24 , which results in a high wearing comfort.

The connecting web 17 extends next to the cap 1 when the head shield 2 is inserted into the cap 1 . It is advantageous if the connecting web 17 rests at least partially on the inner side of the cap shell 3 . The free edge 27 of the housing 6 terminates essentially adjacent to or set back relative to the free end of the cap 1 .

The head guard device is described below, where an external force acts on the vibration-damping structure 14 toward the head receiving cavity 18 . The force acts via the cap shell 3 and is transmitted to the head shield 2 . This force acts on the connecting web 17 , which is here bent or displaced at least partially inwardly in the direction of the head receptacle 18 . At least one connecting body 16 of the displaced connecting web 17 is also deflected. Preferably, the two corresponding connecting bodies 16 are deflected. Preferably, the connecting bodies 16 in question are deflected substantially uniformly. When the connecting bodies 16 are deflected, the connecting bodies 16 of the damping spring arrangement 15 move relative to each other.

The relevant deflection of the connection body 16 can take place in the first connection region 28 between the housing 6 and the corresponding first connection part 19 . The first connection area 28 then forms the first articulation area. Additionally or alternatively, a deflection of the respective connection body 16 can take place in a second connection region 29 which is located between the respective connection web 17 and the respective second connection part 20 . The second connection area 29 thus forms a second articulation area. Alternatively or additionally, a deflection of the connection body 16 can take place between the first connection part 19 and the step part 21 in the third articulation region 30 . Alternatively or additionally, a deflection can take place between the second connection part 20 and the step part 21 in the fourth articulation region 31 .

Deflection basically depends on the direction and magnitude of the force. The loaded faces also play an important role.

With sufficient force, the connecting web 17 can partially sink into the recess 24 . The window 26 thus changes its shape during the application of the force.
