[0001] Headgear

[0002] DESCRIPTION

[0003] The invention relates to a visor for headgear, wherein the headgear comprises a headband worn around the head, namely around the forehead and back of the head, in the position of use for fastening the visor to the head of a wearer.

[0004] The term "use position" refers to the position in which the headgear is usually worn on the head by the end user. In other words, the headgear is "in use position" if this position represents a common way of wearing the headgear.

[0005] The visor serves to protect against direct and indirect sunlight. Depending on the size and shape of the visor, other parts of the body, such as the neck, throat, and shoulders, can be covered and shaded to a greater or lesser extent. However, the visor can also cover only certain areas of the head, for example, just the front of the head or parts of it, similar to sun visors, which primarily protect the face and eyes.

[0006] Unlike baseball caps, sun visors have only a peak but no crown, leaving the top of the head exposed.

[0007] Sun visors offer the wearer good ventilation and a more open feel and are particularly popular for outdoor activities such as golf, tennis or running, but also in everyday life as casual headwear for the summer.

[0008] As already mentioned, the headband primarily serves to secure the visor to the wearer's head. It is worn around the head, specifically around the forehead and back of the head, in the intended use position. Worn in this way, the headband represents an essential feature of the invention, without which the invention could not achieve its full effect. This feature also defines the type of headgear. The invention is limited to this type.

[0009] Over the years, various head coverings have been proposed to protect against sun exposure:

[0010] US 3,585,643 A (Ruby A. Ryan) describes a sun hat with a disc 10 having a diameter larger than the head to provide shade for the head, and provided with fastening means arranged to hold the disc 10 flat against the head. The head fastening means comprise, in one embodiment (Figs. 1-3), a flexible headband 12 and a pair of flexible straps 16 and 18, whose opposite ends 20 are attached to the headband 12.

[0011] A central portion of the straps is slidably guided through slots 22 and 23 in the pulley 10, allowing the pulley 10 to be adjusted to various angular positions on the head by relative displacement along the straps 16 and 18. Preferably, the pulley 10 is made of a lightweight but structurally stable material, such as expanded or foamed plastic.

[0012] Ruby A. Ryan's sun hat impresses with its simplicity. Nevertheless, sun hats of this type have not yet established themselves on the market. One reason for this is likely the cumbersome handling of the headgear. Handling is complicated due to the flexible straps 16 and 18, requiring the use of both hands. The distance of the disc 10 from the wearer's head is fixed and limited by the fact that the disc 10 rests against the head. To still effectively cool the head through convection, the inventor proposes designing the visor as a flat disc 10. However, this shape is not well suited to protecting the wearer's head from direct and diffuse solar radiation.

[0013] US 4,109,322 A (Charlotte A. Ott) describes a sun shield 10 consisting of a flat, heat-insulating protective element 11 that is held above the head 15 of a wearer by means of an arm 13. The arm 13 is pivotally attached to a headband 12 and, at the other end, is pivotally connected to the insulating element 11, so that the insulating element 11 can be moved by adjusting the arm 13 and rotating the headband 12 to shade the wearer's head 15 from above and from all sides. The headband 12 includes an elongated, arcuate plastic part 16 to which the arm 13 is pivotally connected.

[0014] The flat protective element 11 can be made of any suitable lightweight material, but is preferably made of a non-heat-conductive material such as a thin, elastic plastic, paper, foam rubber, or the like, with sufficient thickness to retain its shape and provide good protection from the sun. The arm 13 is essentially formed from a thin strip of elastic plastic.

[0015] Charlotte A. Ott's sun protection shield is a remarkable

[0016] This represents a further development in that the distance between the flat protective element 11 and the wearer's head 15 is no longer limited as in the previously described case, but can be freely selected by changing the length of the arm 13. This allows the wearer's head 15 to be cooled much more effectively by convection. However, this sun protection shield has not yet been able to establish itself on the market. A weak point is the arm 13, which, as mentioned, is essentially formed from a thin strip of elastic plastic. It seems questionable whether such an arm could hold the protective element 11 securely above the head. Such an arm would also be disadvantageous in terms of feel. Headgear is considered clothing. Wearers associate clothing with warmth, softness, and suppleness. The arm 13 exhibits none of these properties. The same applies to the elongated, curved plastic part 16, to which the arm 13 is pivotally mounted.

[0017] US 4,109,322 A further teaches that the protective element 11 should be flat. As already pointed out earlier, a flat or level shape is not well suited to protecting the wearer's head from direct and diffuse solar radiation. Certainly, someone could object that, in this specific case, the protective element 11 could be adjusted almost arbitrarily by adjusting the arm 13 and rotating the headband 12 in order to shade the wearer's head 15 from above and from all sides. However, this involves considerable effort: the wearer of the sun shield must continuously adjust the protective element 11 to ensure optimal protection from solar radiation. These constant adjustments would quickly tire the average end user.

[0018] To securely attach the protective element 11 to the head, it is proposed to design the headband 12 as an elastic rubber band 17. The elastic rubber band 17 can be flexibly pre-tensioned, thus ensuring a secure fit on the head. On the other hand, the rubber band 17 can quickly create a feeling of tightness in the wearer, which significantly impairs wearing comfort and is therefore considered a significant defect.

[0019] US 4,114,201 A (Harold K. Garrison) describes in one embodiment (Figs. 9-10) a hat having a central crown portion, generally designated C, with a brim 80 extending therearound and with an upper brim 80a positioned over the lower brim 80 and also extending around the crown portion C.

[0020] Furthermore, as shown, a hatband portion 81 extends around the wearer's head. A sweatband 23a is provided to support the hat on the wearer's head. Such sweatband 23a extends partially around the circumference of the hatband portion 81 and can also extend around the full circumference if desired.

[0021] A plurality of upwardly and inwardly curved struts 83 are arranged at circumferential intervals around the circumference of the hatband portion 81 to support the upper brim 80a and simultaneously form a plurality of circumferential air inlets or vents 85 which allow air to enter, move within, and exit the crown C.

[0022] The hat may be formed from a lightweight plastic foam material such as Styrofoam or the like and may consist of an integral one-piece construction.

[0023] The hatband section 81, as mentioned, extends around the wearer's head and serves to support the hat on the head via the sweatband 23a. Since heads vary considerably in size and shape, the hat must be offered in various sizes and, in the case of a different head shape, must also be adjusted to fit them. Today's end consumer often has neither the patience nor the leisure to adjust a hat to their head shape. If the retailer provided this service, the associated effort would ultimately lead to an increase in the price of the headgear.

[0024] There is also a concern that the hat band portion 81 which fits tightly to the head, especially if it is made of Styrofoam or the like as proposed, could impair air circulation around the head and the removal and evaporation of perspiration.

[0025] WO 87 / 01014 A1 (Anthony James Jephson Emmett) describes a hat

[0026] 10 comprising a hat body 11 with a circumferential brim 12. Near the junction 13 between them, a headband 14 is provided, which is placed around the wearer's forehead. Spacers 15 secure the headband 14 at intervals on the lower inner periphery.

[0027] 16 of the hat body 11, forming ventilation openings 17 between the wearer's head and the hat body 11. The hat body

[0028] 11 comprises a lower body portion 18 and an upper crown portion 19, which, as best shown in Fig. 6, are connected to one another via inclined supports 32 to form passage openings 20. The passage openings 20 allow air to flow from the inside of the hat to the outside. This allows the air heated by the wearer's head within the hat body 11 to pass through the lower ventilation openings.

[0029] 17 and pass below the crown portion 19 through the passage openings 20 to the outside of the hat to cool the wearer's head. The hat 10 can be supported by any suitable means effective to maintain the distance from the wearer's head. Furthermore, no further details are given regarding the spacers 15. It is also unclear how the spacers 15 are connected to the hat body 11 on the one hand and the headband 14 on the other.

[0030] It is clear that heads vary considerably in size and shape. The spacers 15 must therefore be adapted to the respective head size and shape in each individual case and connected to the hat body 11 and the headband 14. Apart from the fact that there is uncertainty about how this adaptation and the joining of the parts should be carried out—WO 87 / 01014 A1 provides no information on this—the associated effort would be considerable and unreasonable for the average end user.

[0031] WO 87 / 01014 A1 teaches that the headband 14 could alternatively be omitted. In this case, the spacers 15 support the hat body 11 directly against the wearer's head. However, this does not reduce the effort required to adjust the spacers 15.

[0032] The inadequate disclosure regarding the spacers 15 raises fundamental questions about the feasibility of the invention.

[0033] The invention is based on the object of eliminating the previously identified disadvantages of the arrangements known from the prior art. The invention is particularly based on the object of designing a visor for headgear of the type mentioned at the outset such that the wearer is optimally protected from incoming solar radiation, while the head is effectively cooled by convection. The visor should be held securely and stably on the head. The headgear should be safe to use and easy to handle. The headgear should be lightweight, consist of only a few parts, and be cost-effective to manufacture. Furthermore, the headgear should be easily adjustable to a specific head size and shape. Last but not least, the headgear should be perceived haptically as a piece of clothing and offer a high level of comfort.

[0034] The object is achieved in that the visor consists essentially of foam and, for its support, forms on the visor surface facing the head in the position of use at least one elevation with a joining surface overlapping the headband for connection to the headband, wherein the joining surface overlaps the headband in the position of use only at the forehead.

[0035] The term "forehead" refers to the protruding part of the front of the head above the eyes. The forehead is bounded by the edge of the frontal bone (Latin: os frontale).

[0036] The term "elevation" refers to a body that protrudes from the canopy's surface. This term does not restrict the shape of the body in any way.

[0037] The raised part is formed by the peak and is made of the same material as the peak, i.e., the same foam. Because the peak and its support, i.e., the raised part, are made of foam, impacts can be effectively absorbed. The integral construction of peak and raised part allows for a uniform feel for these components that define the headgear, thus increasing the headgear's comfort. The raised part holds the peak in its intended use position above the wearer's head. The raised part also acts as a spacer, creating a gap between the peak and the head. This improves air circulation around the wearer's head and thus helps cool the head.

[0038] The surface of the umbrella consists of: the surface facing the head in the use position, the surface facing away from the head in the use position, and the surface at the edge of the umbrella. The raised area is formed on the surface facing the head in the use position. The exact location of the raised area can be freely chosen. This design flexibility makes it possible to support even very large umbrellas.

[0039] The visor forms at least one raised portion with a joining surface that overlaps the headband to hold it in place, and can therefore also have several such raised portions. This creates several joining surfaces that overlap the headband.

[0040] A protrusion can also branch into several branches, each of which has a joining surface that overlaps the headband.

[0041] The joining surface of a raised portion can also be composed of several separate joining surfaces that overlap the headband.

[0042] As the examples show, there may be multiple joining surfaces and / or partial joining surfaces that overlap the headband. The characteristic that "the joining surface only overlaps the headband at the forehead in the wear position" then applies to all joining surfaces and partial joining surfaces. However, it may also be the case that several elevations merge and form a common joining surface that overlaps the headband. In this case, too, the joining surface only overlaps the headband at the forehead in the wear position.

[0043] The presence of a joining surface in itself represents an essential feature of the invention, as it allows the properties of the headband to be determined independently of the foam visor. The resulting design flexibility can be used to improve the comfort of the headgear. For example, a textile headband can be provided to secure the foam visor to the head. Joining foams with other materials, especially textiles, is only used in niche sectors and is therefore anything but obvious.

[0044] The joining surface overlaps the headband only at the forehead when in use. Thus, when in use, the headband is only connected to the raised area at the forehead, while its remaining sections fit flexibly and adaptably against the head. This allows the headgear to be produced in a standard size, at least for adults, and reduces manufacturing costs. Adjusting the headgear to an individual head size and shape is also simplified and is primarily achieved by adjusting the length of the headband.

[0045] The arrangement offers further potential: By carefully designing the raised portion and its joining surface, as will be shown later, the structural properties of the headgear can be adapted to those of a baseball cap. The headgear can then be handled like one. Given the widespread use of baseball caps in Western countries, it is advantageous to maintain a familiar handling method.

[0046] Apart from minor components, the headgear according to the invention consists of only two parts: the visor and the headband. This simple construction significantly reduces manufacturing costs. Despite its simplicity, the headgear still offers maximum comfort.

[0047] According to the invention, the raised portion overlaps the head only at the forehead when in use. Overlapping in the aforementioned context requires direct contact or close proximity. If multiple raised portions are present, the above feature naturally applies to all raised portions. This arrangement ensures that air circulation around the head is minimally disrupted.

[0048] In a further development of the invention, the elevation has a hump-like shape, i.e., a hump-like elevation whose surface forms a shell, with the joining surface arranged on the shell. The special geometry of the elevation and the arrangement of the joining surface create an exceptionally stable structure.

[0049] In an advantageous embodiment of the invention, the raised portion is hollowed. The hollowing of the raised portion can be performed from any side. For example, the hollowing can be performed from the side of the visor facing away from the head. Access to the hollow can optionally be closed with a lid.

[0050] It is particularly advantageous if the elevation has the shape of a protuberance. A protuberance is present when the elevation is hollowed out from the side of the visor facing away from the head, and the hollow at least approximately follows the shape of the elevation.

[0051] In a preferred embodiment of the invention, only a single protrusion is provided to secure the visor to the headband. Although foam is a relatively flexible material, it is surprising that even when using particularly lightweight foam types with low density and strength, a single foam protrusion is sufficient to secure the visor to the headband.

[0052] In an alternative embodiment of the invention, only two protrusions are provided to secure the visor to the headband. The two protrusions are advantageously arranged in mirror image on either side of a plane of symmetry of the visor. The two protrusions can be dimensioned narrower than a single protrusion. The gap formed between the two protrusions can be used for air circulation.

[0053] In a further development of the invention, the raised portion in the area of ​​the joining surface is provided with reinforcement in the form of a reinforcing insert, overlay, or / and covering. The reinforcement locally strengthens the foam. Stress and strain peaks in the foam are reduced, and deformations remain limited.

[0054] It is particularly advantageous if the reinforcement forms the joining surface. The reinforcement thus serves an additional purpose here, namely that of a connecting means by mediating the connection between the headband and the foam of the raised part. In this embodiment of the invention, the reinforcement is preferably made of solid plastic. According to the invention, the reinforcement is welded to the foam of the raised part. The welding of foam materials has only recently been explored and is used only in niche applications. The applicant is aware of only a few applications in which foam parts have been joined to solid plastic parts by welding.

[0055] In an advantageous embodiment of the invention, the reinforcement is formed by a sleeve through which the headband can be threaded. To reduce weight, the wall of the sleeve can optionally be perforated. In this case, the sleeve and headband form a positive connection. The positive connection is achieved through the geometric contact of active surfaces, in this specific case through the contact of the inner surface of the sleeve and the surface of the headband. In this embodiment of the invention, the joining surface is formed by the inner surface of the sleeve. By definition, the elevation has a joining surface for connection to the headband. Since, as previously stated, the joining surface is formed by the sleeve, the sleeve is part of the elevation. It is only logical and consistent to consider the reinforcement as part of the component it is strengthening.

[0056] In an alternative embodiment of the invention, the reinforcement is formed by a shell. To reduce weight, the shell can optionally be perforated. In this embodiment of the invention, the joining surface is formed by the shell, for example by welding it flat to the headband. By definition, the elevation has a joining surface for connection to the headband. Since, as stated above, the joining surface is formed by the shell, the shell is a component of the elevation. It is only logical and consistent to consider the reinforcement as a component of the component that is reinforced by it. The invention further relates to headgear with a visor, as described above, and a headband worn around the head in the use position, namely around the forehead and back of the head, for attaching the visor to the wearer's head.

[0057] A further embodiment of the invention relates to headgear with a visor, as described above, and a headband worn around the head, specifically around the forehead and back of the head, for securing the visor to the wearer's head in the use position. According to the invention, the headband is directly welded to the foam of the raised portion. In this case, the foam itself forms the joining surface. This design is impressive due to its minimalist construction, particularly due to the reduced number of components.

[0058] In a further development of the invention, the visor has a receptacle for a headrest on the visor surface facing the head in the use position. While the visor is primarily attached to the head by means of the headband and the raised area, the headrest serves to provide additional support for the visor. The headrest can only transmit supporting forces. However, its effect should not be underestimated. The headrest can noticeably increase wearing comfort because it allows the headband to sit more loosely on the head. Without a headrest, the weight of the headgear could only be kept in equilibrium by static friction between the headband and the head. However, static friction can only be created by tightening the headband, which can make the wearer feel tight.

[0059] In addition, it can be provided that the screen is on the

[0060] When in use, a rounded indentation forms near the front edge of the canopy, facing the head. The "front edge" is the section of the canopy that is at the very front when in use. The rounded indentation facilitates handling by providing support for the fingers.

[0061] Finally, the canopy can be designed with a bulge at the front edge. This bulge also provides a better grip for the fingers during handling. By stiffening the canopy at the front edge, the bulge also helps maintain the canopy's shape and thus the symmetry of the field of view.

[0062] The invention is explained in more detail below using two exemplary embodiments, which are illustrated in the figures. They show:

[0078] Fig. 22 is a sectional view according to the cutting line VV in Fig. 21.

[0079] Figs. 1-4 show a first embodiment of the headgear 1 according to the invention in its use position in various views. The headgear 1 includes a foam visor 2, which has a circular shape in the form of a bowl. As Fig. 5 shows, the visor 2 surrounds the head 3 of a wearer and, in the use position, is arranged at a distance above the head 3 such that the bowl base 4 is opposite the crown 5, i.e., the uppermost part of the head 3. In order not to restrict the wearer's field of vision too much, the front visor edge 6 is raised slightly.

[0080] In an area opposite the wearer's forehead 7 in the use position, the visor 2 forms a raised portion 8 extending in front of the forehead 7, where it is connected to the headband 9. The headband 9 serves to attach the visor 2 to the head 3 and, in the use position, is worn around the head 3, namely around the forehead 7 and the back of the head 10.

[0081] The elevation 8 holds the visor 2 in its position of use above the wearer's head 3 and simultaneously acts as a spacer by creating a gap or gap 11 between the visor 2 and the head 3. The gap 11 serves to facilitate air circulation around the wearer's head 3. Ambient air can thus directly reach and cool the wearer's head 3. Cooling occurs partly through convection and partly through evaporation of sweat. The sweat evaporates directly on the scalp, removing heat from it, which ultimately results in the cooling effect. The resulting water vapor is carried away by the surrounding ambient air, causing the water vapor partial pressure near the scalp to drop. This further promotes evaporation and enhances the cooling effect.

[0082] As shown in Figs. 1 and 4, only a single protrusion 8 is provided to secure the visor 2 to the headband 9. The protrusion 8 is arranged in front of the forehead 7 and, in the use position, overlaps the head 3 only at the forehead 7. This only slightly impedes the air circulation around the head 3.

[0083] Since the elevation 8 is formed by the screen 2, it is made of the same foam as the latter. The screen 2 and the elevation 8 thus form an integral, one-piece construction, which is preferably produced by foam molding. In foam molding, pre-expanded particles are sintered into molded parts, usually under steam, but more recently also steamless using electromagnetic waves. The raw material, i.e. the foam particles or beads, can be obtained, for example, from JSP Corporation (JSP), Shin-nisseki Building, 3-4-2 Marunouchi, Chiyoda-ku, Tokyo 100-0005 Japan, or from its subsidiaries. JSP markets such raw material under the trademarks ARPAK® and ARPRO®, where ARPAK® refers to expanded polyethylene (EPE) and ARPRO® refers to expanded polypropylene (EPP). The screen 2 including the elevation 8 can, for example, be foam-molded on molding machines from Kurtz GmbH & Co. KG, Frankenstraße 2, 97892 Kreuzwertheim, Germany.It has proven particularly advantageous to process foam beads with a bulk density of 12 to 35 grams per liter. These are the lightest beads commercially available today. Molded parts or visors 2 made from them are comparatively pliable and soft, feel warm to the touch, and are most similar to clothing in terms of feel. Headwear is considered a type of clothing. The haptic properties of a headwear product can determine whether a consumer accepts or rejects it.

[0084] It is surprising that even when using particularly lightweight foam types of lowest density and strength, a single elevation 8 is sufficient to securely hold even larger umbrellas 2 on the headband 9, wherein it is advantageous if the elevation 8 has a compact shape. In the exemplary embodiment of the invention shown here, the elevation 8 has a hump-like shape. The hump-like shape contributes to the stability of the structure. This is due to the compact shape that is typical of hump-like elevations. However, the invention is not limited to the hump-like elevation 8. The elevation 8 can also have a different shape.

[0085] 7 and 8 show the elevation 8 – in this specific case the hump-like elevation 8 – and its connection to the headband 9 in detail. Fig. 7 refers to Fig. 6 by showing detail E on an enlarged scale. As can be seen from Fig. 7, the elevation 8 is hollowed, i.e. has a recess 12. In this specific case, the hollowing out of the elevation 8 takes place from the side of the visor facing away from the head 3, but can in principle take place from any side. In the exemplary embodiment shown here, the recess 12 approximately follows the shape of the elevation 8. In this special case, the elevation 8 can also be considered a protuberance. However, the shape and size of the recess 12 can vary. By hollowing out the elevation 8, an accumulation of material can be avoided and the cycle time during foam molding can be reduced. Access to the recess 12 is closed with a cover 13. The lid 13 may bear a logo or trademark on its outside.

[0086] The elevation 8—in this specific case, the hump-like elevation 8—forms a lateral surface or casing 14 on its surface. The end of the hump-like elevation 8 is flattened, but could also be round. The hump-like elevation 8 is connected to the headband 9 via a sleeve, preferably a plastic sleeve 15, on the side of the casing 14 facing the head 3 in the position of use. This arrangement lends the structure exceptional stability. The plastic sleeve 15 is preferably manufactured by injection molding, although it may be advantageous to design the plastic sleeve 15 in two parts and to join the two halves, for example, by ultrasonic welding.

[0087] The headband 9 is threaded or can be threaded through the plastic sleeve 15, i.e., is detachably connected to the visor 2. The headband 9 can therefore be removed from the headgear 1 if it becomes unusable or needs to be cleaned.

[0088] The headband 9 consists of a flat, flexible, preferably textile band, for example a woven webbing, whose cross-section essentially corresponds to the opening of the plastic sleeve 15 through which the headband 9 is threaded or can be threaded. The connection between the headband 9 and the plastic sleeve 15 is thus a positive connection, with the joining surface 16 being formed by the inner surface of the plastic sleeve 15. The wall of the plastic sleeve 15 can be generously perforated for the purposes of ventilation and weight savings. Fig. 9 shows the plastic sleeve 15 with the threaded headband 9. Fig. 10 shows the plastic sleeve 15 and its two-part structure in detail.

[0089] The plastic sleeve 15 extends flat over the casing 14 of the raised portion 8 and is firmly bonded to the foam. This bond can be adhesively bonded. However, it is preferably welded, primarily because this allows for greater strength. The bonded connection to the comparatively stiff plastic sleeve 15 reinforces, i.e., reinforces, the foam in this area.

[0090] The joining surface 16, i.e., the inner surface of the plastic sleeve 15, overlaps the headband 9 in the use position only at the forehead 7. In this context, reference is also made to Figs. 1 and 4, from which the arrangement is already clearly evident, even if the plastic sleeve 15 is concealed. The arrangement has the effect that the headgear 1 can be manufactured in a standard size, at least for adults, and the adjustment of the headgear 1 to an individual head size and shape can be achieved primarily by means of the headband 9 by adjusting its length. The headband 9 is equipped with an adjustment mechanism for this purpose. This can consist, for example, of a buckle such as a ladder buckle, clamp buckle, clamp-ladder buckle, or a hook-and-loop fastener. Such adjustment and closure elements are commercially available. The adjustment mechanism is not shown in the figures.However, the arrangement has even further potential: Through targeted design of the elevation 8 and the plastic sleeve 15, the structural properties of the headgear 1 can be adapted to those of a baseball cap. The compact shape of the hump-like elevation 8 stiffens the visor 2 in the front visor area. The plastic sleeve 15 also has a slight curvature on the side facing the head 3 in the position of use, which follows the contour of the forehead 7. The inner region of the plastic sleeve 15, which forms a positive connection with the headband 9, is also curved accordingly. The curvature is thus also transferred to the headband 9. The headgear 1 is thus given a specific shape on the forehead 7, which replicates the contour of the forehead 7. Designed in this way, the headgear 1 bears similarities to baseball caps, whose comparatively stiff visor also follows the contour of the forehead. The headgear 1 can therefore be handled like a baseball cap.Given the widespread use of this headgear, it becomes clear how advantageous it is to be able to maintain a familiar way of handling.

[0091] The side of the plastic sleeve 15 facing the elevation 8 is flat. This flat geometry simplifies the joining processes, namely the ultrasonic welding of the two sleeve halves on the one hand and the creation of the welded connection between the plastic sleeve 15 and the elevation 8 on the other. The inwardly directed ribs 17 serve to guide the headband 9 in a form-fitting manner within the plastic sleeve 15. They force the headband 9 to assume a curvature that follows the contour of the forehead 7 and was already mentioned above.

[0092] Considering that the entire load transfer on the screen 2 occurs via the raised portion 8, it becomes clear that the integral connection between the plastic sleeve 15 and the foam must be resilient. As the applicant was able to demonstrate in its own welding tests, the welded joint represents a very strong and secure connection that can only be severed by destroying the material.

[0093] The welding of foams has only recently been explored and is used only in niche applications. When creating the welded joint, care must be taken to ensure that the material of the plastic sleeve 15 is selected from a single material. The general rule is that only identical thermoplastics can be welded together homogeneously. For example, if the foam is made of expanded polypropylene (EPP), the plastic sleeve 15 must also be made of polypropylene. If, on the other hand, the foam is made of expanded polyethylene (EPE), the plastic sleeve 15 must also be made of polyethylene.

[0094] The welded joint can be created using various methods. Examples include heated element welding and infrared welding. In the first case, the plastic sleeve 15 is melted on the side facing the foam by physical contact with a heating element – ​​i.e., by heat conduction – and then the plastic sleeve 15 is pressed, melted side first, against the foam. In the second case, the plastic sleeve surface is melted using an infrared radiator. Such radiators can be purchased, for example, from Excelitas Noblelight GmbH, Heraeusstraße 12-14, 63450 Hanau, Germany. Our own welding tests have shown that it is sufficient to melt only the surface of the plastic sleeve 15. The foam melts during joining solely through contact with the plastic sleeve 15. This is due to the extremely low density and low thermal conductivity of the foam.The weld can alternatively be created using ultrasound. During ultrasonic welding of plastics, ultrasonic waves are introduced into the component using a sonotrode. Frictional heat is generated and leads to the melting of the component surface. The joining partners can then be joined under additional pressure. In order to weld using ultrasound, the energy of the sound waves must be concentrated. For this purpose, the plastic sleeve 15 must be suitably designed on the side facing the foam by providing so-called energy directors. These are straight, protruding connecting elements, such as prongs, that extend into the foam and have pointed ends. The energy directors focus the sound waves and simultaneously create a positive connection.MultiMaterial-Welding AG, Zentralstrasse 115, 2503 Biel, Switzerland, has advanced ultrasonic foam welding to series production and offers this joining technology commercially under the name LiteWWeight® zEPP. The technology utilizes the MM-Welding® process, in which a thermoplastic joining element is driven into the foam using ultrasound. Partial melting creates a bonded joint, while the special geometry of the joining element also ensures a positive fit within the foam.

[0095] Finally, the welded connection between the plastic sleeve 15 and the foam can be created by particle foam composite injection molding (PVSG). In this process, which is commercially offered by Krallmann Kunststoffverarbeitung GmbH, Siemensstraße 24, 32120 Hiddenhausen, Germany, the thermoplastic compact material is injected directly onto the foam. Only the top layer of the foam is melted, so that both components are bonded together. According to the invention, when using this process, the plastic sleeve 15 would be injected directly onto the foam.

[0096] In order to avoid foam collapse at low particle foam densities, the procedure can alternatively be reversed, by inserting the plastic sleeve 15 into the tool cavity of the molding machine and then partially foaming it in the molding process.

[0097] Fig. 11-13 illustrate the headgear 1 in various assembly stages, in which add-on parts are added step by step. Fig. 11 shows the peak 2 as a semi-finished product after foam molding, but still without the plastic sleeve 15, i.e. before joining. In an industrial production environment, the handling, positioning and joining of the peak 2 and the plastic sleeve 15 is preferably carried out fully automatically, without manual intervention. For this purpose, the peak 2 must be brought into a defined joining position. It may be advantageous to mechanically support the elevation 8 to prevent bending during joining. The plastic sleeve 15 is then aligned on the peak 2, in turn brought into a defined joining position and pressed against the foam with the already melted side first without delay, whereby the plastic sleeve 15 is driven a predefined distance into the foam.This locally compresses the foam and increases the strength of the welded joint. Fig. 12 shows the headgear 1 after joining, and Fig. 13 shows it with the headband 9 threaded through the plastic sleeve 15. As Fig. 11 shows, the visor 2 has a recess next to the raised portion 8 on the visor surface facing the head 3 in the use position.

[0098] 18 for a headrest 19. The headrest 19 is most clearly shown in Figs. 5, 6 and 12.

[0099] While the umbrella 2 is primarily held above the head 3 by means of the elevation 8, the headrest 19 merely serves to provide additional support for the umbrella 2 on the head 3. In contrast to the elevation 8, the headrest

[0100] 19 only transmits supporting forces. However, its contribution as a fastening element should not be underestimated. If positioned correctly, it can even keep the umbrella 2 balanced on the head 3 all by itself.

[0101] The receptacle 18 serves to hold the headrest 19. In the specific embodiment of the invention, the receptacle 18 consists of a circular recess in the umbrella surface. The recess serves to assist the end user in correctly attaching the headrest 19 to the intended location. The attachment of the headrest 19 to the umbrella 2 is preferably carried out by the end user themselves. In this way, they can adapt the headgear 1 to their individual head shape. The headrest 19 has the shape of a cylinder whose circular end fits exactly into the receptacle 18, i.e., into the circular recess. To enable individual adjustment, the cylindrical headrest 19 can be offered in various lengths, so that the end user can select the headrest 19 that best suits their needs from a range.The circular end of the headrest 19 is preferably provided with a self-adhesive coating, which allows the headrest 19 to be attached to the screen 2 without additional tools. The receptacle 18 is by no means limited to a circular recess. A simple circular marking ultimately serves the same purpose and could alternatively serve as the receptacle 18.

[0102] The headrest 19 can, for example, be made of open-cell polyurethane foam, or PUR foam for short. The open-cell structure makes the foam particularly soft and flexible, allowing it to absorb sweat like a wick, store it, and release it through evaporation. The foam structure thus also contributes to cooling the head 3, since evaporation is always associated with heat removal from the environment. Headrests 19 made of PUR foam can be purchased ready-to-use from Oskar Pahlke GmbH, Linzer Straße 95, 53562 St. Katharinen, Germany.

[0103] Near the front edge 6 of the shield, the shield 2 forms a rounded recess 20 on the surface facing the head 3 in the use position. The rounded recess 20 serves for handling by providing support for the fingers. This feature is referenced in Fig. 6.

[0104] At the front edge 6 of the visor 2, a bulge 21 forms - see Fig. 6 and Fig. 14. The bulge 21 also serves to facilitate handling of the headgear 1 by providing grip for the fingers. The bulge 21 also improves the shape retention of the visor 2 in this area. The front edge 6 limits the field of vision. The field of vision should always be symmetrical. Deformations in this area lead to asymmetry and should therefore be avoided. The bulge 21 helps maintain the shape of the visor 2 and thus the symmetry of the field of vision.

[0105] The shield surface can be rubberized in the area of ​​the rounded recess 20 and / or in the area of ​​the bulge 21. The rubber coating gives the surface more grip and thus further improves handling.

[0106] Figs. 15 and 16 show an alternative design of the elevation 8. Two elevations 8 are arranged side by side to secure the visor 2 to the headband 9. The two elevations 8 are advantageously arranged in mirror image on either side of a plane of symmetry of the visor 2. The gap 22 between the two elevations 8 can be used for air circulation.

[0107] A plastic shell 23 bridges the gap 22 and forms the connecting means to the headband 9. The curvature of the plastic shell 23 approximately follows the contour of the forehead 7.

[0108] The plastic shell 23 is integrally connected, preferably welded, to the two elevations 8. Regarding the manufacture of the welded connection, reference is made to the corresponding explanations for the plastic sleeve 15, which are applicable analogously.

[0109] The convex side of the plastic shell 23 is optionally equipped with nubs 24, which penetrate the foam during joining and additionally provide a positive fit. If the parts are ultrasonically welded, pointed prongs can be provided instead of the nubs 24 to bundle and focus the sound energy.

[0110] Like the plastic sleeve 15, the plastic shell 23 is preferably manufactured by injection molding. The primary function of the comparatively rigid plastic shell 23 is to reinforce the foam by locally strengthening it.

[0111] On the headband side, the plastic shell 23 is welded flat to the headband 9. In this embodiment, the concave shell surface, which is flatly connected to the headband 9, forms the joining surface 16. Again, the joining surface 16 overlaps the headband 9 in the use position only at the forehead 7. The advantageous effects of this arrangement have already been explained earlier.

[0112] The welded connection with the headband 9 can be created, for example, by laser transmission welding – a single-step joining process in which the plastic surface is melted using laser light. For this to happen, one of the two joining partners, i.e., either the headband 9 or the plastic shell 23, must have high laser transparency, while the other joining partner largely absorbs the laser light. This must be ensured during component manufacture by using only suitable, possibly modified, raw materials. Before welding, the two joining partners are positioned in the desired final position, and a joining pressure is applied. The laser beam then passes through the transparent joining partner without significant heating.The laser beam hits the surface of the second joining partner and is largely absorbed there, melting the plastic in a layer close to the surface and bonding it firmly to the transparent joining partner. The welded joint can be produced, for example, using laser welding systems from Trumpf Laser- und Systemtechnik GmbH, Johann-Maus-Straße 2, 71254 Ditzingen, Germany.

[0113] The rule again applies that only identical thermoplastics can be welded together homogeneously. If, for example, the foam is made of expanded polypropylene (EPP), the plastic shell 23 must also be made of polypropylene. In this case, the headband 9 can consist of a textile, such as a woven fabric made of polypropylene fibers. Textile fibers made of polypropylene have properties that make them ideal for use in sports and outdoor textiles. The low weight of these fibers is worth highlighting. Textiles made of polypropylene also hardly absorb any moisture, but can very well transport moisture to the outside. There, on the surface of the textile, the sweat can quickly evaporate, leaving a pleasantly dry wearing feeling. In the simplest case, the headband 9 can consist of a woven webbing made of polypropylene. Such webbing is commercially available in various widths and thicknesses.

[0114] If, however, the foam is made of expanded polyethylene (EPE), the plastic shell 23 must also be made of polyethylene. In this case, the headband 9 can be made of a textile, such as a woven fabric made of polyethylene fibers. While polypropylene is widely used in textiles today, especially in functional textiles for outdoor use, this has not been the case for polyethylene to date. This is surprising, given that the excellent properties of this synthetic fiber were recently confirmed – see "Sustainable polyethylene fabrics with engineered moisture transport for passive cooling," Nature Sustainability Volume 4, 715-724 (2021).

[0115] Fig. 17-22 show a second embodiment of the headgear 1 according to the invention. In this embodiment, the visor 2, which is again made of foam, is significantly smaller and covers only parts of the head 3. The protection now applies primarily to the front part of the head 3 by shielding the face from direct sunlight and protecting the eyes from glare.

[0116] In this respect, the headgear 1 according to this second embodiment represents the equivalent of sun visors—called "visor caps" in English—with the difference that the peak 2 is positioned at a distance from the head 3. While in conventional sun visors the shield is directly connected to the headband via the rear edge, this connection and dependence are eliminated in the headgear 1. With the headgear 1 according to the invention, the design flexibility for the arrangement of the peak 2 on the wearer's head 3 is considerably greater. This makes it possible to optimally coordinate the shading effects and the air circulation around the head.

[0117] In an area which, in the use position, lies opposite the wearer's forehead 7, the visor 2 forms a raised portion 8 which extends in front of the forehead 7, where it is connected to the headband 9. The headband 9 serves to fasten the visor 2 to the head 3 and, in the use position, is worn around the head 3, namely around the forehead 7 and the back of the head 10. It consists of a flat, flexible, preferably textile band, for example a woven webbing, and has an adjustment mechanism at the back of the head 10 for adapting its length to the wearer's head circumference. This can, for example, consist of a buckle such as a ladder buckle, clamp buckle, clamp-ladder buckle, or a Velcro fastener. Such adjustment and fastening elements are commercially available. The adjustment mechanism is not shown in the figures.

[0118] The elevation 8 holds the visor 2 in its use position above the wearer's head 3 and at the same time acts as a spacer by creating a gap or gap 11 between the visor 2 and the head 3. The gap 11 serves to facilitate air circulation around the wearer's head 3. Ambient air can thus directly reach and cool the wearer's head 3. The cooling effects have already been described in more detail earlier. As Fig. 17 shows, only a single elevation 8 is provided to hold the visor 2 to the headband 9. The elevation 8 is arranged in front of the forehead 7 and, in the use position, only overlaps the head 3 at the forehead 7. As a result, air circulation around the head 3 is only slightly impeded.

[0119] Since the raised portion 8 is formed by the screen 2, it is made of the same foam as the screen. The screen 2 and the raised portion 8 thus form an integral, one-piece construction, which is preferably manufactured by molded foam. The molded foam process has already been described previously.

[0120] Once again, it proves particularly advantageous to process foam beads with a bulk density of 12 to 35 grams per liter. These are the lightest beads commercially available today. Shades made from these beads are lighter than those of conventional sun visors, even if they are larger. Shades made from such lightweight raw materials are also comparatively pliable and soft, feel warm to the touch, and are most similar to clothing in terms of feel.

[0121] As shown in Figs. 21 and 22, the elevation 8—in this specific case, the hump-like elevation 8—forms a shell surface or shell 14 on its surface. Fig. 21 refers to Fig. 20 by showing detail X on an enlarged scale. The end of the hump-like elevation 8 is flattened, but could also be round. The elevation 8 is connected to the headband 9 on the side of the shell 14 facing the head 3 in the position of use. In contrast to the previously illustrated embodiments of the headgear 1 according to the invention, the connection is not made indirectly, i.e., with the aid of a connecting means, but directly. Specifically, it is provided that the headband 9 is welded directly to the foam of the elevation 8.

[0122] The part of the lateral surface 14 on which the joining partners, i.e. the elevation

[0123] 8 and the headband 9 are welded together, forming the joining surface 16. The joining surface 16 overlaps the headband 9 in the use position only at the forehead 7. In this context, reference is also made to Fig. 17, from which the arrangement is already clearly evident, even if the joining surface 16 is concealed. The joining surface 16 has a slight curvature, which follows the contour of the forehead 7 - see Fig. 22. Due to the material connection between the elevation 8 and the headband

[0124] 9, the curvature is also transferred to the headband 9. The headgear 1 is thus given a specific shape at the forehead 7, which replicates the contour of the forehead 7. The compact shape of the hump-like elevation 8 also stiffens the visor 2 in the front area of ​​the visor. Designed in this way, the headgear 1 bears similarities to baseball caps and sun visors, whose comparatively stiff visors also follow the contour of the forehead, and can therefore be handled in the same way. Given the widespread use of these headgear, it becomes clear how advantageous it is to be able to maintain a familiar handling method.

[0125] Since the illustrated embodiment does not include reinforcement of the joining surface 16 in the form of a reinforcing insert, overlay, or covering, alternative measures can be taken if necessary to ensure the dimensional stability of the shield 2 and protect the foam structure from excessive stress. For example, it would be possible to locally increase the foam density in the area of ​​the joining surface 16 by, as an exception, incorporating foam particles or beads with a higher bulk density than usual into this critical area during foam molding. An increase in foam density is accompanied by an increase in the modulus of elasticity. According to Hooke's law, a higher modulus of elasticity leads to lower elongation and deformation.

[0126] Infrared welding, for example, is suitable for creating the welded connection between the raised portion 8 and the headband 9. The headband 9 is melted using an infrared heater in a surface area corresponding to the joining surface 16. It is recommended to specifically shield adjacent areas of the headband 9. The headband 9 is then pressed, with the melted side first, against the raised portion 8 without delay and welded to it. It is advisable to mechanically support the relatively flexible raised portion 8 during this process.

[0127] The rule again applies that only identical thermoplastics can be homogeneously welded together. For example, if the foam is made of expanded polypropylene (EPP), the headband 9 must also be made of polypropylene. In this case, the headband 9 can be made of a textile, such as a woven polypropylene fiber. The excellent properties of this chemical fiber have already been described in detail elsewhere. In the simplest case, the headband 9 can be made of a woven polypropylene webbing. Such webbing is commercially available in various widths and thicknesses.

[0128] If, however, the foam is made of expanded polyethylene (EPE), the headband 9 can advantageously be made of a textile, such as a woven fabric made of polyethylene fibers. The potential of this chemical fiber as a starting material for the production of functional textiles in the outdoor sector has already been discussed previously.

[0129] Foam beads made of expanded polyethylene (EPE) and expanded polypropylene (EPP) are primarily available in the classic basic colors of black and natural white. There are also varieties with improved UV resistance. The natural white foam beads have an advantage due to their high degree of reflection from sunlight. However, they are minimally translucent, which hardly impairs the protective function of the headgear. If this is not satisfactory, colored raw material can be used instead of the standard natural white material to optimize the protective function and add aesthetic accents. However, JSP Corporation (JSP) only offers a limited range of colors in its standard product range. The colored varieties are also only available in certain bulk densities.One example is "ARPRO 35 Ocean," which is made from 15% recycled marine industrial waste and features an attractive turquoise color. However, it can be assumed that JSP will expand the range as larger orders are placed, taking into account specific customer preferences.

[0130] It is also possible to provide the visor surface with a texture. Modern manufacturing technologies in mold making, such as fine structuring of the tool's inner surface using a laser, now allow the creation of fine and high-quality surface textures. This not only enhances the visor surface's appearance, but also allows its haptic properties to be specifically designed. The company T. Michel Formenbau GmbH & Co. KG, In der Zeil 10, 56355 Lautert, Germany, builds molds for foam molding and also offers laser texturing. Finally, it should be noted that the headgear 1 can be equipped with a sweatband that fulfills various functions. The most important of these are the functions of sweat transport and sweat evaporation. Furthermore, the sweatband is intended to increase the wearing comfort of the headgear 1 by sitting snugly and softly against the head 3.

[0131] The sweatband can, for example, be made of a functional textile that regulates moisture, dries quickly, and increases comfort through breathability. Alternatively, it can also be made of terry cloth. It is particularly advantageous if the sweatband is detachable from the headband 9. In this case, the sweatband can be cleaned separately. The sweatband is not shown in the figures.

[0132] The above description of preferred embodiments of the invention is for the purpose of explanation and illustration. It is not exhaustive and does not limit the invention to the specific embodiments described. Various modifications and variations will be apparent to those skilled in the art. The embodiments were chosen to best explain the principles of the invention and its practical applications, and they were described in sufficient detail to enable those skilled in the art to practice the teachings disclosed herein.

[0133] Embodiments and modifications such as those described below are also within the technical scope of the present invention:

[0134] In the illustrated embodiments, the headband 9 is always worn closed around the head 3, i.e., around the forehead 7 and the back of the head 10. However, this closed wearing manner is not mandatory. The headband 9 can alternatively be connected to the elevation 8 via two free ends. The design according to Fig. 15-16 could, for example, be modified by attaching two free ends of the headband 9 to the ends of the plastic shell 23. The attachment could be achieved, for example, by a welded connection. Alternatively, the plastic shell 23 could form slit-shaped openings at its ends through which the free ends of the headband 9 are threaded - similar to what is shown in US Pat. No. 4,109,322 A. These modified embodiments clarify that the headband 9 does not necessarily have to completely enclose the forehead 7.

[0135] In the illustrated embodiments, the headband 9 is always connected to the elevation 8 on the side of the casing 14 facing the head 3. However, this need not be the case. Two alternative embodiments are shown as examples:

[0136] In the first case, the headband 9 is worn closed around the head 3 and encloses the elevation 8 on the side of the jacket 14 facing away from the head 3. In this embodiment, the elevation 8 is clamped between the headband 9 and the forehead 7.

[0137] In the second case, the headband 9 has two free ends that are attached to the flanks of the raised portion 8. The term "flanks" refers to the lateral sections of the casing 14 where the casing surface facing the head 3 merges into the one facing away from it. The fastening is achieved, for example, by means of plastic tabs that are welded to the foam of the raised portion 8 and reinforce the raised portion 8 on its flanks.

[0138] The exemplary embodiments demonstrated that it is advantageous to match the structural properties of the headgear 1 to those of baseball caps, and presented concrete design approaches for this. These aimed to stiffen the headgear 1 in the front visor area and to shape it at the forehead 7 so that it follows the contour of the forehead 7. The adaptation of the structural properties can also be applied to the sections of the headband 9 that rest freely on the forehead 7. If the headband 9 consists of a textile band made of polypropylene or polyethylene fibers, it can be specifically shaped and stiffened by thermoforming, whereby the textile fibers partially sinter and / or fuse. The functional properties of the textile, such as absorbency and breathability, are retained.

[0139] The structural properties of the headgear 1 can be further adapted to those of baseball caps by reinforcing the headband 9 in the forehead area 7. If the headband 9 is made of a textile band, for example, the reinforcement can be achieved by additional textile layers or by a supporting reinforcement, such as a supporting fabric or an insert. Finally, a separate sweatband could also provide support for the headband 9.

[0140] The measures just described for adapting the structural properties of the headgear 1 to those of baseball caps can be taken independently or in a complementary manner.

[0141] For all embodiments of the invention, the joining surface 16 is the surface on which the elevation 8 is connected to the headband 9. The joining surface 16 is the specific location where the elevation 8 and the headband 9 are joined together. In the case of a positive connection, the joining surface 16 is the surface on which the elevation 8 and the headband 9 are in contact, i.e., the location where the effective surfaces of the positive connection touch each other. If the elevation 8 is provided with reinforcement and this forms the joining surface 16, then the reinforcement is to be considered a component of the elevation 8. It is only logical and consistent to consider the reinforcement as a component of the component that is reinforced by it.

[0142] It should also be mentioned that the headgear 1 according to the invention can optionally be equipped with a headlamp. The headlamp could, for example, be structurally integrated into the bead 21. The associated battery could be housed in the recess 12 and could be easily accessed after removing the cover 13.

[0143] Finally, it should be noted that while umbrella 2 is primarily designed for sun protection, it also offers good protection in the rain. Headgear 1 is therefore suitable for a variety of weather conditions.
