Description

Bracket for a temple part

The invention relates to a holder for a temple part.

The bracket can be used in many contexts. An example of use arises in connection with hearing protection. Such hearing protection is used in particular in environments in which the hearing and eyes or face of people are to be protected. This creates, for example, increased safety in the workplace, for example for forest workers, on construction sites or for other occupations that are associated with a risk to the hearing and eyes of people. Glasses with tinted lenses are also used as sun protection.

The term "hearing protection" is used here. This is very general to understand. It also relates to devices that are provided for communication or only for listening to music or for perceiving other communications. A conventional headphone with ear cups and headband is "hearing protection" in the sense of the present disclosure. The generic combination of "hearing protection" and "headphones" is evident as modern hearing protection devices are often equipped with means of communication. In other words, the protective earmuffs often contain a loudspeaker and possibly an interface for a microphone in order to enable the persons concerned to communicate.

The invention has for its object to provide a bracket for a temple part so that glasses can be swiveled comfortably between a working position, that is, a position in front of a wearer's eyes, and a parking position, that is, a position in which the glasses are not is in front of a wearer's eyes and is in particular superscript, in particular to avoid that the glasses are unintentionally pivoted between the two positions. This object is achieved with the features of the independent claim. Advantageous embodiments of the invention are specified in the dependent claims.

The invention consists in a holder for an eyeglass front part, with an eye and a spring arm, the eyeglass front part can be clipped into the eye by means of spring lugs provided on the eyeglass front part, the eyeglass front part being pivotable between a working position and a parking position by rotation of the spring lugs in the eye is and wherein the spring arm is moved against a spring force during a pivoting movement of the eyeglass temple front part and secures the eyeglass temple front part in the park position. The connection between the front part of the temple and the holder is detachable, so that the glasses can be replaced in a simple manner. One and the same pair of glasses can also be used for different applications. The eyeglass temple front part can be pivoted against the spring force of the spring arm without effort, the spring arm securing the parking position of the eyeglass temple front part. In general, the park position is a raised position of the glasses. The glasses want to leave this position due to gravity. The spring arm prevents this.

It is usefully provided that the spring arm lies in a relaxed position in a base plane that is parallel or identical to a plane that is defined by the eye, and that the spring arm leaves the base plane during the pivoting movement. In this way, the eye and the spring arm provide a compact configuration of the holder. A slight exit from the base plane by the spring arm is sufficient to allow the front part of the temple to pivot. If you consider swiveling from the working position to the park position, the spring arm is preferably initially in its base plane, although a certain preload and leaving the base plane are already possible. If the temple is swiveled at the front, the spring arm swings out of the base plane. After reaching the parking position, the spring arm pivots again in the direction of the base plane or entirely into the base plane. Then the spring arm can prevent a swiveling back of the temple part from the park position into the working position.

This is realized in particular in such a way that a securing extension is arranged on the spring arm, which does not extend parallel away from the spring arm and secures the eyewear front part in the parking position. The securing extension prevents an intentional leaving the parking position by the front part of the temple like a hook, so that the parking position is reliably secured.

In this way, an eyeglass temple is provided with an eyeglass temple front part and a holder, the eyeglass temple front part having spring lugs, via which it can be clipped into the eye of the holder, and wherein the eyeglass temple front part adjacent to the spring lugs has a projection which, when the The front part of the temple strikes the securing extension and thus moves the spring arm out of the base plane and which is held in the parking position by the securing extension in order to secure the front part of the temple in the parking position.

The invention further relates to glasses with at least one glasses bracket according to the invention.

Furthermore, such a hearing protection with glasses is made available, the hearing protection having at least one earmuff and a headband and the glasses having two glasses for fastening the glasses to the hearing protection, wherein the fastening of the glasses to the hearing protection by fastening the glasses bracket done on the headband. The attachment of the glasses to the headband of the hearing protection is the basis for a particularly simple constructive solution. The point of attachment of the glasses to the hearing protection is preferably so far away from an earmuff that can be connected to the headband that the glasses and the earmuffs can be moved independently and in particular do not hinder their movement. It is not necessary to equip the ear protectors with earhooks that provide the option of attaching the glasses to them. Rather, the hearing protection can be equipped with different types of carrying arms, because the interface between glasses and hearing protection is assigned to the constructive basic element of hearing protection, namely the headband. Thus, it is ultimately the constructive construction of headband and glasses in which the basic idea of the invention is anchored. Based on this, the hearing protection has a high degree of design variability. It should be noted that in addition to the different types of hearing protection mentioned above, namely without means of communication, with means of communication or as mere headphones, different glasses can also be used. The glasses can have a purely mechanical protective function, they can be open at the edge to allow good ventilation. It can be closed at the edge to also prevent any harmful substances from penetrating from the edge, for example wise of chemicals. The glasses can provide sun protection. Likewise, the glasses can be a visual aid, so-called optical glasses. The glasses can also be designed so that they can also be called visors. This can be a full visor or a half visor. All of the above-mentioned properties of glasses can be combined in part or in total.

It is usefully provided that the headband has at least one pivot axis on which the at least one earmuff is pivotally mounted, and that a bracket for a spectacle arm is attached to the at least one pivot axis. The swivel axis provided for the earmuffs is used so that the hearing protection can be put on comfortably, and it provides a variable and therefore secure installation of the hearing protection on the hearing of the wearer. The pivot axis receives a dual function on the basis of this embodiment. It not only serves to attach the earmuffs, but also to attach the glasses. This provides a particularly simple and rational construction.

Furthermore, it is of particular advantage that the at least one pivot axis has receptacles at its ends and that the bracket of the eyeglass temple is attached to the at least one pivot axis by means of counterparts that fit into the receptacles. The counterparts provided on the glasses fit into the receptacles of the swivel axis, so that the glasses are thereby securely held on the headband. The counterparts are arranged on clip-like end pieces of the temple piece, the clip-like end pieces encompassing the headband in a positive and / or non-positive manner.

It is advantageous that the counterparts are pegs.

It is particularly useful that at least one temple piece is at least three parts, a headband part provided as the holder being articulated with an intermediate part and a front part being slidably mounted in the intermediate part. The intermediate part and the front part together form the front temple part. As a result, the glasses are not only pivotally attached to the headband, but the length of the glasses temple is also adjustable. As a result, the fit of the glasses can be varied, for example in order to choose different settings under different working conditions. This also ensures that the hearing protection fits every wearer. The articulation can also be present between the front part and the intermediate part, while the displaceability is then arranged between the headband part and the intermediate part. In this context, it is advantageous that the front part can take at least two locking positions in the intermediate part. The locking positions ensure that the temples do not accidentally change in length.

Furthermore, the hearing protection according to the invention can be designed such that the at least one ear protector is mounted on the at least one pivot axis via a fork-shaped support bracket. The fork-shaped carrying arms are pivotally connected to the headband via the pivot axis, to which the glasses are also attached. The actual earmuffs can easily be hung in the bracket.

It is particularly useful that the earmuff is mounted on the support bracket via two pins. The storage of the earmuffs on pins on the bracket allows light that the earmuffs can be pivoted in the bracket.

The invention further relates to glasses for use with hearing protection according to the invention.

The invention further relates to a headband for use with a hearing protection according to the invention.

In the following description of the drawings, identical reference symbols designate identical or comparable components.

FIG. 1 shows part of a hearing protection device 10 with an eyeglass temple according to the invention, an eyeglass temple front part 112 being in a working position. FIG. 2 shows part of a hearing protection device 10 with an eyeglass temple according to the invention, an eyeglass temple front part 112 being in a parking position. FIG. 3 shows a holder for an eyeglass temple front part 112 fastened to a support bracket of a hearing protector 10. FIG. 4 shows part of an eyeglass temple front part 112. FIG. 5 shows part of an eyeglass temple front part 112. FIG. 6 shows a holder for an eyeglass temple front part 112. The eyeglass temple front part 112 comprises a Intermediate part 36 and a front part 34. The front part 34 is connected to the spectacle lenses 124. Spring lugs 118 are arranged on the intermediate part 36. Furthermore, a projection 122 is provided adjacent to the spring lugs 118. see. The bracket 110, which is also referred to in the present case as a headband part 32, comprises an eye 114 and a spring arm 116. A securing extension 120 is arranged on the spring arm 116, which in the present exemplary embodiment extends perpendicular to the spring arm 116. In FIG. 6, the securing extension 120 emerges from the plane of the paper in the direction of the viewer. The assembly of an eyeglass temple 20, 22 can be illustrated with the aid of FIGS. 5 and 6. For this purpose, the eyeglass front part 112 is pressed with its spring lugs 118 into the eye 114 of the holder 110, namely from the direction of the viewer into the plane of the paper. As soon as the temple part 112 and the holder 110 are locked together, the temple part 112 can be pivoted in the holder 110. If one looks at the pivoting from the working position shown here to the left using the example of FIG. 1, the projection 122 comes into contact with the securing extension 120, as a result of which the spring arm is moved against a spring force, namely toward the viewer in the illustration according to FIG 6 away from the viewer. As soon as the projection 122 has passed the securing extension 120 completely, the spring arm 116 can move back with the spring force. This state is reached in Figure 2. The spring arm 116 with the securing extension 120 now represents an obstacle for the projection 122. In general, gravity is not sufficient for the projection 122 in turn to spring the spring arm so far that the glasses 12 unintentionally fall back into the parking position. This usually only works if the wearer of the glasses 12 puts his hand on and actively causes the glasses 12 to pivot from the park position into the working position.

FIG. 7 shows a frontal view of a hearing protection device 10. The hearing protection device 10 comprises a headband 18. Supporting clips 38 are attached to the headband 18 in an articulated manner. The pivot axes 24, which make the articulation available, run essentially in the viewing direction of the viewer of FIG. 1. Ear protectors 14, 16 are articulated on the support brackets 38. The articulation is provided by pins 40 and corresponding measures on the earmuffs 14, 16. Neither the pegs nor the receptacles can be seen in the illustration, since they are covered by the support brackets 38 or the earmuffs 14, 16. An earmuff 14 is an earmuff equipped with communication means. It contains a loudspeaker and a microphone 42 is connected to it. The communication means can work via a wireless radio communication interface, for example a Bluetooth interface. The other earmuff 16 is a passive earmuff, that is, it only serves to protect the ear, and it does not contain any means of communication. It is also possible that the other ear protector 16 is also equipped with communication means, similar to the first ear protector 14. In another variant, one of the ear protectors, for example the first ear protector 14, is equipped with communication means, as described, while the other ear protector, for example the ear protector 16 , it makes it possible to listen to music, for example via a digital radio function. This need not necessarily be integrated into the earmuffs 16, but it can be made available with the aid of a digital radio function of a mobile telephone, in particular a smartphone, so that it is sufficient if the earmuffs 16 have means for receiving, possibly also for transmitting , and means for reproducing sound are easily seen. Spectacles 12 are also attached to the headband 18. These glasses 12 include, among other components, a transparent pane 44 and attached eyeglass temples 20, 22. At the ends of the eyeglass temples 20, 22, clip-like holders 46, 48 are provided. These holders 46, 48 partially surround the headband 18.

FIG. 8 shows a perspective side view of a hearing protection device 10. The multi-part construction of the spectacle arms 20, 22 can be seen here. Each eyeglass temple 20, 22 comprises a headband part 32, that is to say the holder 110 for the front eyeglass temple part 112, the end of each headband part 32 being provided with the holder 46, 48 via which the eyeglass temples 20, 22 are connected to the headband 18. Each headband part 32 is connected to an intermediate part 36 via a hinge axis 50. These hinge axes 50 make it possible to pivot the glasses 12 upwards, that is to say in the direction of the headband 18. The intermediate parts 36 slidably receive front parts 34. An intermediate position is shown. The front part 34 can be pulled out further from the intermediate part 36 or it can be pushed further into the intermediate part 36. In this way, the length of the temple 20, 22 is changed overall. Figure 2 fer ner shows in some detail at which point the pivot axis 24, via which the support bracket 38 are connected to the headband 18, relative to the holders 46, 48 of the temple 20, 22 is. In particular, the pivot axis 24 connects the clip-like extensions of the holders 46, 48. The active earmuffs 14 have operating elements 52 on their outside for controlling the communication.

FIG. 9 shows a perspective side view of hearing protection 10, the glasses 12 being detached from the headband 18 on one side. Due to the release of its holder th 48 you can now see more precisely the pivot axis 24, via which the carrier 38 are connected to the bracket 18. Such a pivot axis 24 comprises a pin 54, which in each case penetrates one end of the headband 18 and the carrier 38. The ends of each pin 54 has receptacles 26 (see FIG. 5). If the holders 46, 48 clasp the headband 18 in this area, pins 28, 30 (see FIG. 4) are received by the receptacles 26, so that the holders 46, 48 find a secure hold on the headband 18.

FIG. 10 shows a detail of the fastening device with which an eyeglass temple 20, 22 can be fastened to the headband 18. The holder 46, which is designed as a clip-like end piece of a temple 20, comprises a central part lying in the rear viewing direction, and two end pieces which jump towards the viewer in the viewing direction. Pins 28, 30 are arranged on the end pieces and extend essentially in the paper plane of FIG. 4. These pins 28, 30 are held in the receptacles 26 (see FIG. 5).

FIG. 11 shows a detail of the fastening device to which an eyeglass temple 20, 22 can be fastened. Here the pin 54 serving as pivot axis 24 is recognizable at the end and is represented by two concentric circles. The inner circle marks the outer circumference of a receptacle 26 for one of the pins 28, 30 (see FIG. 4).

FIG. 12 shows a detail of the hearing protection 10, the three-part construction of an eyeglass temple 20, 22 being recognizable. In this respect, it comprises a headband part 32 with Hal ter 48, an intermediate part 36 and a front part 34.
