The invention relates to a support for a temple front portion.
In particular, the support can be deployed in numerous contexts. An exemplary area of application arises in connection with a hearing protector. Such a hearing protector is, in particular, used in environments in which the hearing and the eyes or the face of persons are to be protected. In this way, for example, enhanced safety at the workplace is established, for example for forestry workers, at construction sites or in other occupations involving a risk to the hearing and eyes of persons. Also, eyeglasses with tinted glasses are used as sun protection.
Here, the term “hearing protector” is used. It is to be understood in a very broad sense. It also relates to devices provided for communication or only just for listening to music or for performing other communication. A conventional headphone having ear cushions and head pieces is, insofar, also a “hearing protector” within the meaning of the present disclosure. The generic approximation of “hearing protector” and “headphones” becomes obvious in that modern hearing protection means are frequently equipped with communication means. In other words, the protecting ear protectors frequently contain a loudspeaker and possibly an interface to a microphone to render communication possible to the persons concerned.
Underlying the invention is the object to provide a support for a temple front portion so that the glasses are comfortably pivotable between a work position, i.e. a position in front of the eyes of a wearer, and a parking position, i.e. a position in which the glasses are not positioned in front of the eyes of a wearer and are, in particular, folded upwards, in which connection it is, in particular, to be avoided that the glasses are unintentionally pivoted between the two positions.
This object is solved by the features of the independent claim. Advantageous embodiments of the invention are indicated in the dependent claims.
The invention relates to a support for a temple front portion including an lug and a spring arm, the temple front portion being clippable into the lug by means of spring tabs provided on the temple front portion, the temple front portion being pivotable between a work position and a parking position by a rotation of the spring tabs in the lug, and the spring arm being moved against a spring force during a pivoting movement of the temple front portion and securing the temple front portion in the parking position. The thus established connection of the temple front portion to the support is releasable so that the glasses can be exchanged in a simple manner. Furthermore, one and the same glasses can be used for various applications. The temple front portion may be pivotable against the spring force of the spring arm without effort, the spring arm securing the parking position of the temple front portion. In general, the parking position is a folded-up position of the glasses. The glasses seek to leave this position due to gravity. This is prevented by the spring arm.
Usefully, it is contemplated that the spring arm is located in a base plane which is parallel or identical to a plane defined by the lug is in a relaxed position, and that the spring arm leaves the base plane with the pivoting movement. In this way, the lug and the spring arm provide for a compact configuration of the support. A slight departure of the spring arm from the base plane is sufficient to allow for a pivoting movement of the temple front portion. When regarding a pivoting movement from the work position to the parking position the spring arm is preferably first positioned in its base plane, a certain bias and a departure from the base plane also being possible as early as in this stage. When the temple front portion is pivoted, the spring arm is pivoted out of the base plane. After having reached the parking position, the spring arm is again pivoted in the direction toward the base plane or fully into the base plane. Then, the spring arm can prevent the temple front portion from pivoting back from the parking position to the work position.
This is, in particular, realised by a securing projection non-parallelly extending away from the spring arm and securing the temple front portion in the parking position being disposed on the spring arm. The securing projection prevents the temple front portion from unintentionally leaving the parking position like a catch so that the parking position is reliably secured.
In this way, a temple including a temple front portion and a support is provided, the temple front portion having spring tabs via which it can be clipped into the lug of the support, and the temple front portion having a protrusion adjacent to the spring tabs, the protrusion abutting to the securing projection during a pivoting movement of the temple front portion thus moving the spring arm out of the base plane and being held in the parking position by the securing projection to secure the temple front portion in the parking position.
The invention further relates to glasses including at least one temple according to the invention.
Further, a hearing protector including glasses is provided in this way, the hearing protector including at least one ear protector and a head piece, and the glasses including two temples for attaching the glasses to the hearing protector, the attachment of the glasses to the hearing protector being effected by attaching the temple to the head piece. The attachment of the glasses to the head piece of the hearing protector is the basis of a particularly simple design solution. The fixation point of the glasses on the hearing protector is preferably so far removed from an ear protector connectable to the head piece that the glasses and the ear protector can be moved independently and, in particular, do not interfere with each other in their movement. It is not required to provide the hearing protector with support brackets for the ear protector which themselves offer the possibility to attach the glasses thereto. Rather, the hearing protector may be provided with diverse support brackets since the interface between the glasses and the hearing protector is allocated to the basic design element of the hearing protector, namely the head piece. It is therefore ultimately the constructive design of the head piece and the glasses on which the basic idea of the invention is based. On this basis, the hearing protector has a high design variability. It should be noted that, apart from the various aforementioned types of hearing protectors, namely without communication means, with communication means, or as mere headphones, also diverse glasses can be used. For example, the glasses may merely have a mechanical protective function, they may be open at the edge to render a good rear ventilation possible. They may be closed at the edge to prevent any harmful substances, for example chemicals, from entering from the periphery. The glasses may provide for sun protection. The glasses may also be a viewing aid, i.e. they may have so-called optical glasses. The glasses may also be formed so that they can also be referred to as a visor. In this case, they may be a full-face visor or a half visor. All of the abovementioned features of glasses can, in part or in whole, be combinable.
Usefully, it is contemplated that the head piece includes at least one pivot axis on which the at least one ear protector is pivotably supported, and that a support of a temple is fixed on the at least one pivot axis. The pivot axis provided for the ear protector serves to ensure that the hearing protector can be conveniently put on, and it provides for a variable and thus secure abutment of the hearing protector against the ears of the wearer. The pivot axis is given a dual function according to this embodiment. It does not only serve to fasten the ear protector, but also to fasten the glasses. In this way, a particularly simple and rational design is provided.
Furthermore, it is particularly advantageous that the at least one pivot axis includes receptacles at its ends and that the support of the temple is fixed on the at least one pivot axis via mating parts fitting into the receptacles. The mating parts provided on the glasses fit into the receptacles of the pivot axis so that, in this way, a secure support of the glasses on head piece is ensured. The mating parts are disposed on clip-like end portions of the temples, the clip-like end portions positively and/or frictionally enclosing the head piece.
Here, it is advantageous that the mating parts are journals.
It is particularly useful that at least one temple is formed of at least three parts, a portion of the head piece provided as the support being articulately coupled to an intermediate portion, and a front portion being slidably supported in the intermediate portion. The intermediate portion and the front portion together form the temple front portion. In this way, the glasses are not only pivotably attached to the head piece, but the temples are also adjustable in length. In this way, the fit of the glasses can be varied, for example for selecting various settings under different working conditions. Further, it is ensured in this way that the hearing protector fits any wearer. Articulation may also be provided between the front portion and the intermediate portion, slidability then being located between the head piece portion and the intermediate portion.
In this connection, it is advantageous that the front portion can take at least two latched positions in the intermediate portion. The latched positions ensure that the length of the temples does not unintentionally change.
Furthermore, the hearing protector according to the invention can be configured so that the at least one ear protector is supported on the at least one pivot axis via a fork-like support bracket. The fork-like support brackets are pivotably connected to the head piece via the pivot axis to which also the glasses are attached. The actual ear protectors can be readily mounted in the support brackets.
Here, it is particularly useful that the ear protector is supported on the support bracket via two journals. The support of the ear protector via journals on the support bracket ensures that the ear protector is pivotable in the support bracket.
