Description

State of the art

[0001] The invention relates to a protective device 1. Protective devices with a head attachment unit for fastening to a user's head are already known in the prior art. On the one hand, protective devices with protective units in the form of visors, for example welding visors, with a headband for fastening to a user's head are known, see, for example, US 2016 / 361201 A1. On the other hand, protective devices with protective units in the form of hard hats, for example, construction helmets, are known. A disadvantage for users to date is that, depending on the type of work to be carried out, either a protective device in the form of a visor or a protective device in the form of a hard hat must be worn, and these two types of protective devices can only be combined with great difficulty, if at all, for example, because the brim of a hard hat makes it impossible to properly put on a visor.This significantly restricts flexibility. Furthermore, it negatively impacts workplace safety, as the associated effort reduces the motivation to comply with safety regulations requiring the use of different protective equipment for different tasks.

[0002] The object of the invention is, in particular, to provide a generic device with improved flexibility. This object is achieved according to the invention by the features of claim 1, while advantageous embodiments and further developments of the invention can be found in the dependent claims. Advantages of the invention

[0003] The invention relates to a protective device with a head mounting unit for attachment to a user's head and with a mounting unit which is designed to connect a protective unit to the head mounting unit.

[0004] It is proposed that the mounting unit be designed to connect at least one further protective unit to the head mounting unit.

[0005] Such a design advantageously provides a protective device with increased flexibility. Since both the protective unit and the additional protective unit, especially individually or in combination, can be connected to the head mounting unit via the mounting unit, particularly flexible use of the protective device can be advantageously achieved. Furthermore, a protective device with improved ease of use can be advantageously provided. In addition, user safety can be increased. In particular, occupational safety for users can be enhanced. Specifically, the particularly simple and quick connection of the protective unit and / or the additional protective unit can advantageously motivate users to comply with occupational safety regulations, such as the mandatory wearing of helmets on construction sites or the like.

[0006] The protective device is intended for occupational safety, particularly on construction sites and / or in hazardous areas and / or during the performance of dangerous work, such as welding. Preferably, the protective device is designed as a multifunctional device and intended for protection during the performance of various hazardous tasks.

[0007] A "head mounting unit" is understood to be a unit designed for attaching, in particular fixing, the protective device to the user's head. Preferably, the head mounting unit is designed to at least partially encircle the user's head. In this context, "at least partially encircle" means that the head is enclosed by the head mounting unit in at least one plane within an angular range of at least 160°, preferably at least 180°, more preferably at least 270°, and particularly preferably at least 360°. Particularly preferably, in a normal operating state, the head mounting unit is designed to rest against at least the forehead and the back of the user's head.Preferably, the head fastening unit has at least one clamping element by means of which a circumference of the head fastening unit can be adjusted, particularly for different users, and fixed to the respective user's head. Preferably, the head fastening unit includes a sweatband.

[0008] The mounting unit is designed to connect the protective unit and / or the additional protective unit to the head mounting unit, in particular in a detachable manner. The protective device can be designed for use by a user with the connection between the head mounting unit and the protective unit established, but without the additional protective unit. Likewise, the protective device can be designed for use by a user with the connection between the head mounting unit and the additional protective unit established, but without the protective unit. Furthermore, the protective device is designed for use by a user with both the connection between the head mounting unit and the protective unit established and the connection between the head mounting unit and the additional protective unit established simultaneously. The mounting unit has at least one fastening element that is connected to the head mounting unit.Preferably, the mounting unit comprises at least one first fastening element and at least one further first fastening element, which are arranged on a first side, for example, the left side, of the head fastening element. Preferably, the mounting unit comprises at least one second fastening element and at least one further second fastening element, which are arranged on a side opposite the first side, for example, the right side, of the head fastening element. The fastening element(s) of the mounting unit could be detachably connected to the head fastening unit, for example, by a positive and / or force-fit connection. The mounting unit further comprises at least one, preferably at least two, mounting elements.A first mounting element is provided for connection to the head mounting unit on the first side of the head mounting unit via the first mounting element and the second mounting element. A second mounting element is provided for connection to the head mounting unit on the second side of the head mounting unit via the second mounting element and the second mounting element. Preferably, the mounting elements are designed for detachable connection to the respective mounting elements, preferably by means of a positive and / or non-positive connection, for example, a snap-fit ​​connection and / or a clamping connection and / or the like. The mounting unit also has at least one receiving element, preferably at least two receiving elements. A first receiving element of the mounting unit is designed for detachable, in particular positive and / or non-positive, connection to the first mounting element.A second receiving element of the mounting unit is provided for a detachable, in particular positive and / or force-fit, connection with the second mounting element. To connect the protective unit to the head mounting unit, the first receiving element is designed to engage in a first receiving opening of the protective unit. To connect the protective unit to the head mounting unit, the second receiving element is designed to engage in a second receiving opening of the protective unit, located opposite the first receiving opening. Preferably, when connected to the head mounting unit, the protective unit is rotatably mounted on the receiving elements of the mounting unit via the receiving openings. Preferably, the protective unit has a locking element by means of which the protective unit can be fixed in at least two positions relative to the head mounting unit.Preferably, the protective unit can be fixed in a first position relative to the head mounting unit by means of the locking unit, wherein a principal extension plane of the protective unit is oriented at least substantially perpendicular to a principal extension plane of the head mounting unit. Preferably, the protective unit can be fixed in a second position relative to the head mounting unit by means of the locking unit, wherein the principal extension plane of the protective unit is oriented at least substantially parallel to the principal extension plane of the head mounting unit. Furthermore, the protective unit can be fixed in other positions relative to the head mounting unit by means of the locking unit, in particular at various angular positions between the first position and the second position.A "principal extension plane" of an object is understood to be a plane which is parallel to a largest side face of a smallest imaginary cuboid which just completely encloses the object, and which in particular passes through the center of the cuboid.

[0009] Preferably, a horizontal distance between the protective unit and the head mounting unit is adjustable, particularly via the mounting unit. For this purpose, the mounting elements of the mounting unit preferably have several horizontally adjacent detent recesses into which corresponding detent lugs of the receiving elements can be engaged according to the desired horizontal distance. This advantageously allows a distance between the protective unit and the face of the user of the protective device to be set. It is thus possible to switch between an arrangement for users who wear glasses and an arrangement for users who do not. Users without glasses can thereby achieve an optimal field of vision, while those who wear glasses benefit from enhanced wearing comfort.

[0010] A "protective unit" is defined as a unit which, in a connected state with the head attachment unit, is designed to provide at least one protective function to protect the user. This protective function may, but is not limited to, include, for example, face protection, eye protection (e.g., glare protection), head protection (e.g., protection against impacts and the like), respiratory protection (e.g., protection against toxic fumes), and / or skin contact with hazardous substances (e.g., acids and the like). Preferably, the protective unit comprises at least one protective element for providing the at least one protective function. The protective unit may have multiple protective elements, particularly for providing different protective functions.The protective unit may have a frame element in which at least one protective element is received and in which, in particular, the receiving openings for the receiving element of the mounting unit may be arranged. The protective unit may also be designed without a frame element. The protective element may also constitute the entire protective unit. For example, the protective element may be designed as a frameless visor. An "additional protective unit" is understood to be a unit which, in a connected state with the head mounting unit, is intended to provide at least one additional protective function, different from the protective function of the protective unit, for the protection of the user. For example, the protective unit could be intended to provide face protection and / or eye protection, and the additional protective unit could be intended to provide head protection.

[0011] In this document, the term "at least substantially" shall be understood to mean that the deviation from a specified value is less than 25%, preferably less than 10% and particularly preferably less than 5% of the specified value.

[0012] In this document, numerical prefixes such as "first" and "second" serve solely to distinguish between objects and / or to indicate relationships between objects, and do not imply a total number or ranking of the objects. In particular, a "second object" does not necessarily imply the existence of a "first object".

[0013] The term "intended" should be understood to mean specifically designed and / or equipped. The fact that an object is intended for a specific function should be understood to mean that the object fulfills and / or performs this specific function in at least one application and / or operating state.

[0014] The protective device can be designed for use by a user with the connection between the head mounting unit and the protective unit already established, without the additional protective unit. Likewise, the protective device can be designed for use by a user with the connection between the head mounting unit and the additional protective unit already established, but without the protective unit itself. In an advantageous embodiment, it is further proposed that the mounting unit be designed to connect the protective unit and the additional protective unit simultaneously with the head mounting unit. Such a design advantageously improves flexibility and also enhances occupational safety during particularly hazardous work.

[0015] Furthermore, it is proposed that the protective device include a protective unit designed as a shield unit with at least one protective element. This advantageously provides a protective device for the effective protection of a user's face. A "shield unit" is understood to be a unit that, in a normal operating position, is positioned in front of the user's face. Preferably, in its normal operating position, the shield unit is designed to cover at least a substantial part of the user's face. Preferably, in its normal operating state, the shield unit is designed to protect the face, for example, from flying sparks. More preferably, the shield unit is designed to form a protective barrier between a work area and the user's face.

[0016] Furthermore, it is proposed that the protective device include an additional protective unit designed as a helmet shell, in particular a construction helmet shell. This advantageously improves safety. In particular, it enables effective protection of the user's head. The helmet shell is designed to absorb at least a large portion of the impact energy. The term "at least a large portion" is understood to mean at least 55%, advantageously at least 65%, preferably at least 75%, particularly preferably at least 85%, and most advantageously at least 95%. The helmet shell is therefore designed to protect the user's head from falling objects and / or swinging loads and / or during work in confined spaces. Preferably, the helmet shell is made of a plastic, in particular a thermoplastic, for example, polyethylene.The helmet shell can be manufactured using a plastic injection molding process, for example. The helmet shell can be available in various colors, especially warning colors.

[0017] Furthermore, it is proposed that the helmet shell have a forehead cutout. This can advantageously improve wearing comfort for users of the protective device. A particularly compact helmet shell can be advantageously provided. Moreover, simultaneous use of the shield unit and helmet shell can be advantageously enabled if the helmet shell has a forehead cutout.

[0018] Furthermore, it is proposed that the shield unit be designed to cover the forehead opening regardless of its position relative to the head mounting unit. Such a design advantageously increases safety. Preferably, the protective device, in a state where both the shield unit and the helmet shell are connected to the head mounting unit, is designed as a complete protective helmet, particularly a construction helmet, certifiable according to DIN EN 397.

[0019] Furthermore, it is proposed that the mounting unit include a height adjustment mechanism for setting the distance between the helmet shell and the head mounting unit. This can advantageously improve the wearing comfort for users of the protective device. It also allows for easy adjustment of the distance between the helmet shell and the head mounting unit, thus enabling the protective device to be adapted to the individual needs of different users and / or to different application situations.

[0020] Furthermore, it is proposed that the protective device include a harness unit which can be positioned between the helmet shell and the head mounting unit and is designed to transmit force from the helmet shell to the user's head. This advantageously improves safety. The harness unit preferably has at least two straps which are oriented at an angle to each other, particularly perpendicularly, and which can be connected at their respective ends to the helmet shell and / or to the head mounting unit. The straps of the harness unit could be separate from each other and connected to each other, for example, by sewing. The harness unit could be made at least partially of fabric and / or leather or the like. Preferably, the straps of the harness unit are formed in one piece.Preferably, the belt unit is made at least largely, and preferably entirely, of a plastic, for example, a thermoplastic or thermosetting plastic. Preferably, the belt unit is designed as an injection-molded part and manufactured using a plastic injection molding process. This advantageously simplifies manufacturing and assembly.

[0021] Furthermore, it is proposed that the harness unit include a chin strap holder. Such a design advantageously improves the flexibility and ease of use of the protective device. The chin strap holder is designed for the detachable attachment of a chin strap to the protective device. The detachable attachment of the chin strap to the chin strap holder can be achieved by means of a positive and / or non-positive connection, for example, by means of a snap-fit ​​connection and / or a hook-and-loop fastener and / or a clamp connection and / or the like. The chin strap can be part of the protective device. It is also conceivable that the chin strap is an accessory for the protective device. The chin strap advantageously improves the attachment of the protective device to the user's head. Preferably, the chin strap holder of the harness unit has at least two chin strap retaining elements.In an assembled state, in which the strap unit is arranged between the helmet shell and the head mounting unit, a first chin strap retaining element of the chin strap retainer is preferably arranged on a first side of the head mounting unit and a second chin strap retaining element of the chin strap retainer is arranged on a second side of the head mounting unit opposite the first side.

[0022] Furthermore, it is proposed that the shield unit be designed as a welding visor. Such a design advantageously provides a protective device with a particularly high level of safety, especially for use during welding work.

[0023] Furthermore, it is proposed that the protective element of the shield unit incorporate an optical glare protection filter. This can advantageously improve the safety of users of the protective device. An "optical glare protection filter" is understood to be an optical filter that forms a protective glass and / or a plastic protective lens. Preferably, the optical glare protection filter is designed as an optical filter whose light transmission is adjustable. Preferably, the optical glare protection filter is an optical welding protection filter with automatic darkening. Particularly preferably, the optical glare protection filter has at least one liquid crystal layer whose transmission can be switched. Various embodiments of the optical glare protection filter that would appear sensible to a person skilled in the art are conceivable.The optical glare protection filter can also be designed as a so-called "automatic darkening filter" (ADF) or "automatic welding protection filter". Preferably, the optical glare protection filter is fixedly, and in particular positionally, mounted in the shield unit.

[0024] Furthermore, it is proposed that the protective device include at least one additional protective unit, designed as a further shield unit and interchangeable with the shield unit. Such a design advantageously enhances flexibility. In particular, the protective device's range of applications can be extended to a wide variety of work areas, and it can be easily and flexibly adapted to specific requirements if it includes at least one additional protective unit designed as a further shield unit and interchangeable with the shield unit.

[0025] In an advantageous embodiment, it is proposed that the additional shield unit be designed as a transparent visor. This advantageously provides a protective device with increased flexibility. The additional protective unit designed as a transparent visor can, but is not limited to, also provide a splash guard function, for example, when working with high-pressure cleaners or the like.

[0026] In a further advantageous embodiment, it is proposed that the additional shield unit be designed as a forestry sight. Such a design advantageously increases flexibility. In particular, the protective device can be advantageously used for protection during forestry work by means of the additional shield unit designed as a forestry sight. Preferably, the additional protective unit designed as a forestry sight has a further protective element, which is designed as a protective grid, for example, for protection against branches during tree felling and the like.

[0027] Furthermore, it is proposed that the additional shield unit has another protective element, designed as a sunshade. This would advantageously increase flexibility even further. In particular, it would be advantageous to provide sun protection for users of the protective device. Preferably, the sunshade has a UV protection filter. It is also conceivable that the protective element of the shield unit could be interchangeable with the additional protective element of the second shield unit.

[0028] Furthermore, it is proposed that the helmet shell incorporate a ventilation unit with at least one ventilation opening. This can advantageously improve user comfort. Wearing comfort, particularly in warm working environments, can be enhanced by ensuring sufficient ventilation of the user's head via the ventilation unit.

[0029] Furthermore, it is proposed that the ventilation unit include at least one cover element designed to at least partially cover the ventilation opening. Such a design advantageously increases flexibility even further. In particular, it allows for flexible adaptation of the ventilation unit to various application situations of the protective device. For example, during welding work where the user's face is protected by the shield unit, the top of the user's head can simultaneously be reliably protected from sparks if the ventilation opening is at least partially or completely covered by the cover element. Preferably, the degree of coverage of the ventilation unit is adjustable, particularly continuously, between a minimum and a maximum, especially complete, covering of the ventilation opening.

[0030] Furthermore, it is proposed that the mounting unit be formed at least partially integrally with the head mounting unit. Such a design advantageously enables particularly efficient manufacturing. "Integrated" is understood to mean materially bonded, such as by welding and / or bonding, etc., and particularly advantageously molded, such as by single-casting and / or single- or multi-component injection molding. "At least partially integral" is understood to mean that at least one element of the mounting unit is formed integrally with the head mounting unit. Preferably, the mounting element(s) of the mounting unit are formed integrally with the head mounting unit.Alternatively or additionally, further elements of the mounting unit, for example at least one mounting element and / or at least one receiving element of the mounting unit, can be formed integrally with the head mounting unit.

[0031] The protective device according to the invention is not intended to be limited to the application and embodiment described above. In particular, the protective device according to the invention may, to achieve a functionality described herein, comprise a different number of individual elements, components, and units than the number specified herein.
