Technical Field
The present invention relates to a respiratory half mask for filtering the respiratory air of a wearer of the respiratory half mask. In addition, the present invention concerns a method for producing such a respiratory half mask.
Background
Generic breathing half masks are previously known, for example from WO 96/28216 a 1.
US 2004/0069302 a1 discloses a breathing half-mask which can be converted from a folded position into a wearing position. The upper nose portion and the lower chin portion of the respiratory half mask are connected to the base portion of the respiratory half mask by a weld.
US 2011/0155138 a1 discloses another prior art respiratory half mask, which is implemented as a folding mask. The breathing half-mask has a base part on which an upper nose part and a lower chin part are arranged.
Disclosure of Invention
The invention is based on the object of providing an improved breathing half-mask. In particular, respiratory half masks would be very useful or easy to manufacture. A corresponding production method will also be created.
According to the invention, this object is achieved by the features specified in the
It is advantageous if the base part and the chin part extend adjacent to or parallel to each other in the chin part storage position. The base part and the nose part advantageously extend adjacent or parallel to each other in the nose part storage position. The breathing half-mask is particularly flat when both the chin portion and the nose portion are disposed in the stowed position. The respiratory half-mask then presents itself, in particular, in the storage position.
Conversely, the breathing half-mask is preferably disc-shaped when both the chin portion and the nose portion are disposed in the as-worn position. The breathing half-mask is then presented in its particular wearing position. It is appropriate that the base portion, nose portion and/or chin portion comprise at least one reinforcement means, such as a seam, a clip or the like.
The breathing half-mask is preferably realized as a folding or hinged mask. Advantageously the breathing half-mask is symmetrical with respect to the centre plane. As an alternative to this, the breathing half-mask is asymmetric.
The base portion, nose portion and/or chin portion are each preferably multi-layered. Alternatively, the base portion, nose portion and/or chin portion are each a single layer.
The base portion, nose portion and chin portion are advantageously formed of the same material. Advantageously, the breathing half-mask is formed from a filter material. The filter material is, for example, a non-woven material and advantageously enables breathing directly through it. The filter material filters the breathing air. It is advantageous if the breathing half-mask has a particle filter or can be used with gases and vapors.
The respiratory half mask may have at least one inhalation valve and/or exhalation valve. When at least one inhalation valve and/or exhalation valve is present, the base portion, nose portion, and/or chin portion may be made of a material that is air impermeable.
In an advantageous manner, the base part, the nose part and the chin part are already connected together and communicate with each other, for example by means of hinge lines or fold lines. Alternatively, the base portion, nose portion and chin portion are, for example, initially realized separately and then bonded together to form the respiratory half mask. Seams may be used, for example, to join them together.
The at least one head holding device is realized as a belt, a string or the like, for example. It is formed, for example, of rubber or textile. It is advantageous if the length of at least one head restraint is adjustable.
Advantageously, the head restraint receiver is completely circumferentially closed. The head restraint receiver is preferably opened last. Advantageously, at least one head holder is guided, in particular movably guided, in the head holder receiver. Preferably, the at least one head holder is guided, in particular in a movable manner, by the head holder receiver.
Further advantageous designs of the invention are detailed in the dependent claims.
At least one material bonding point of attachment according to the dependent claim 3 is advantageously a non-releasable connection. It is preferably in the form of dots and/or lines. Advantageously, at least one point of material attachment is formed by welding, in particular ultrasonic welding or bonding. The material bonding points are preferably produced by heat and/or pressure. It is advantageous if the side regions and/or the basic part temporarily soften or melt in the region to seal with one another. The fixed connection between the base part and the respective side area is preferably produced after cooling thereof.
The dimensions of the local recess of the nose portion detailed in the
The dimensions of the local recess of the chin portion detailed in the
According to the
The dependent claims 12 to 13 preferably also relate to advantageous designs of the object according to
