Description

[Detailed Description of the Invention] The present invention relates to a spectacle attachment for a full-face mask.

In conventionally known full-face masks, protrusions with small holes are provided on both sides of the eyepiece inside the mask, and pin-shaped attachment pieces protruding from the eyeglass frame are inserted into the small holes. Glasses are attached to the glasses, but this structure has the disadvantage that it is difficult to put on and take off the glasses. Another disadvantage is that the position of the glasses relative to the wearer's eyes cannot be adjusted sufficiently.

An object of the present invention is to provide a spectacles mount for a full-face mask that is easy to put on and take off, and also allows for easy and sufficient adjustment of the position of the glasses relative to the wearer's eyes.

An embodiment of the present invention will be described below.

Figure 1 is a partially cutaway front view of the eyeglass mount according to the present invention with eyeglasses attached, Figure 2 is a right side view of the eyeglass mount shown in Figure 1, and Figure 3 is shown in Figures 1 and 2. FIG. 4, an exploded perspective view of the eyeglass mount, is an explanatory view showing the usage state of the eyeglass mount shown in FIGS. 1 to 3.

In the figure, reference numeral 1 denotes an eyeglass support body, which includes a columnar part consisting of a pair of metal wires 2 and 2' extending approximately parallel to each other at appropriate intervals, and an abutment part slidably attached to the lower end of the columnar part. It consists of 3. The lower end portions of the metal wires 2, 2' are slidably fitted into the abutting piece 3, and are biased in the direction of coming out by a spring 4 provided within the abutting piece 3. 5 is a plug that prevents the spring 4 from jumping out. An eyeglass attachment piece 6 made of rubber or synthetic resin is fitted in the upper part of the metal wires 2, 2' so as to be able to slide and stop astride the metal wires 2, 2'. That is, the eyeglass attachment piece 6 is fitted onto the metal wires 2, 2' in a press-contact manner, and is held at a predetermined position on the metal wires 2, 2' by the press-contact frictional force between the metal wires 2, 2'. (stops), and then its position can be changed by sliding it against the pressing friction force. As clearly shown in FIG. 3, each of the fitting holes 7 and 8 into which the metal wires 2 and 2' of the eyeglass attachment piece 6 fit is provided with the eyeglass attachment piece 6, respectively.
Since the cut grooves 9 and 10 that open on the side surfaces are connected, the eyeglass mounting piece 6 is inserted between the metal wires 2 and 2', as shown by the two-dot chain line A in FIG. When the eyeglass mounting piece 6 is rotated in the direction of the arrow toward the position shown by the chain line B, the fitting holes 7 and 8 of the eyeglass mounting piece 6 fit into the metal wires 2 and 2', respectively, so that the eyeglass mounting piece 6 can be attached to the eyeglasses. It can be easily attached to the support 1. The eyeglass mounting piece 6 is provided with a pair of holes 12, 12', and by fitting the pair of horns 14, 14' of the eyeglasses 13 into the holes 12, 12', the eyeglasses 13 can be attached.
is installed.

The usage of the eyeglass mount described above is as follows. The eyeglass mount (see FIG. 4) is configured such that the abutment piece 3 at the lower end of the columnar portion is pressed against the lower edge stepped portion of the eyepiece 16 inside the mask 15, and the upper end of the columnar portion is attached to the upper edge of the eyepiece. By engaging with the corners present in the mask 15, the mask 15 is firmly and securely attached to the inside of the mask 15. Therefore, to remove the glasses support 1 from the mask 15, simply grasp the upper part of the columnar part of the glasses support 1 with your hand and pull it away from the mask 15. After attaching the eyeglasses 13 to the eyeglass attachment piece 6, by sliding the eyeglass attachment piece 6 up and down along the columnar portion of the eyeglass support 1, the eyeglasses 13 can be set at an appropriate height position. In addition, the glasses mounting piece 6
The distance between the wearer's eyes and the spectacle lenses can be adjusted by adjusting the insertion depth of the horns 14, 14' of the glasses 13 that are fitted into the holes 12, 12'.

In the embodiment described above, the lower ends of the metal wires 2, 2' of the eyeglass support 1 are slidably fitted into the contact piece 3, and the elasticity of the spring 4 that presses the lower ends of the metal wires 2, 2' is controlled. The lower ends of the metal wires 2, 2' are fixed to the contact piece 3, and the bending elasticity of the metal wires 2, 2' themselves is used to attach the spectacle support 1 to the mask 15. Then, the spectacle support 1 may be attached to the mask 15. In this case, the lower ends of the metal wires 2, 2' may be appropriately bent and brought into direct contact with the lower edge step of the eyepiece inside the mask, without providing the abutment piece 3.

The columnar part of the eyeglass support 1 includes a pair of metal wires 2,
2′, it has moderate bending elasticity,
The whole or only the fitting portion of the eyeglass attachment piece 6 may be made of a rod-like material or a band-like material having a non-circular cross section. The purpose of making the cross section non-circular is to prevent the eyeglass mounting piece 6 from rotating around the columnar portion of the eyeglass support 1.

The eyeglass mounting piece 6 may be made of a suitable metal such as a light alloy.

The eyeglasses 13 may be attached to the eyeglass attachment piece 6 by other suitable coupling means without using the horns.
Further, the cross section of the horns of the glasses 13 may be made non-circular so that the number of horns is one.
