Description

[Detailed explanation of the invention] (1) Industrial application field The present invention relates to goggles for helmet wearers used by occupants of motorcycles, competition cars, etc.
In particular, it relates to improvements in goggles whose frames are received in helmet windows.

(2) Prior Art In conventional goggles, the upper surface of the frame is formed into a flat surface (see, for example, Japanese Utility Model Application Publication No. 159918/1983).

(3) Problems to be solved by the invention When the goggles having the structure described above are used by a person wearing a helmet, the frame received in the window of the helmet may come into contact with the upper edge of the window. Due to the abutment, there is no gap between the frame and the upper edge of the window, so the helmet wearer's forehead is less likely to be exposed to the wind while driving, resulting in the inconvenience of feeling hot and humid in the summer.

The present invention was developed in view of the above circumstances, and a ventilation passage is secured between the frame and the upper edge of the helmet window over a wide range in the left and right directions, and the ventilation path is provided between the frame and the upper edge of the helmet window. To provide goggles for a helmet wearer which can apply a well-balanced running wind and is effective in preventing bending deformation of a frame.

B. Structure of the device (1) Means for solving the problem In order to achieve the above-mentioned object, the present invention has a structure in which the upper surface of the frame is formed so as to be able to abut the upper edge of the window of the helmet, so that ventilation can flow between them. The frame is characterized in that a pair of left and right protrusions defining a path are provided close to both ends of the frame in the left and right direction.

(2) Effect Even if the goggle frame approaches the upper edge of the window of the helmet due to relative movement between the goggles and the helmet due to vibrations, etc., by bringing the pair of left and right protrusions into contact with the upper edge, Since a ventilation path can be secured between the upper edge and the top surface of the frame over a wide range in the left and right directions, the driving wind that enters the helmet through the ventilation path is distributed in a well-balanced and wide range to the left and right of the wearer's forehead. can be applied to.

In addition, the pair of left and right protrusions, which are located near both left and right ends of the frame, disperse the load received by contact with the upper edge of the window to the left and right, so that the upper side of the frame has relatively high bending rigidity, The upper part of the frame can receive the same load stably and firmly.
There is no risk that the central portion, which has relatively low bending rigidity, will undergo bending deformation.

(3) Embodiment An embodiment of the present invention will be described below with reference to the drawings.

1 is a perspective view of the goggles G of the present invention, and FIG. 2 is a sectional view taken along the line -- in FIG. 1, showing the relative positions of the frame 1 and the helmet H when the goggles G are in use.

The frame 1 of the goggles G is made of synthetic resin and includes an endless peripheral wall 2 and a front flange 3 protruding from each inner and outer peripheral surface of the front and rear ends of the peripheral wall 2.
and a rear flange 4.

A groove 5 is formed in the inner circumferential surface of the front flange 3, into which the peripheral edge of a synthetic resin windshield lens 6 is attached, thus closing the open front surface of the frame 1.

Further, a plurality of ventilation holes 7, 7... are bored in the peripheral wall 2 at appropriate intervals, and these ventilation holes 7, 7...
A band-shaped filter 8 made of urethane foam is bonded to the outer peripheral surface of the peripheral wall 2 so as to cover it.

Further, an endless pad 9 is bonded to the end face of the rear flange 4.

Furthermore, a pair of attachment rings 10, 10 are fixed to both left and right ends of the front flange 3, respectively, and both ends of an elastic band 11 for attachment are connected to both attachment rings 10, 10.

The frame 1 is adapted to be received in a window Ha of a helmet H, as shown in FIG.
On the upper surface of the front flange 3 of this frame 1, a first
As shown in FIGS. 1 and 2, a pair of left and right protrusions 12, 12 are provided in close proximity to both left and right ends of the frame 1, and these protrusions are formed so as to be in contact with the upper edge of the window Ha. A ventilation path 13 is defined between 12 and 12.

Next, the operation of this embodiment will be explained.

When the helmet wearer puts on the goggles G, the pad 9 is brought into close contact with the face of the operator M at the window Ha of the helmet H, and the elastic band 11 is
Put it under tension and hang it on the outer circumferential surface of the helmet H.

In this way, when a helmet wearer wearing goggles G operates, for example, a motorcycle, the frame 1 of goggles G and the helmet H may be damaged due to vibration etc.
When frame 1 approaches the upper edge of window Ha due to the relative movement of
2 and 12 abut against the upper edge of the window Ha, respectively, to regulate the approach distance uniformly over the entire horizontal direction of the frame 1, and between these projections 12 and 12, a ventilation passage 13 is formed over a wide range in the left and right direction. Since this still exists, the helmet wearer can receive the running wind on his forehead in a well-balanced manner in the left and right directions through this ventilation passage 13.

In addition, since the wind passing through the ventilation path 13 reliably acts on the ventilation hole 7 on the top surface of the frame 1 through the filter 8, ventilation within the frame 1 is promoted and the inner surface of the windshield lens 6 is prevented from fogging. can.

It goes without saying that the helmet used with the goggles G of the present invention may be of any type, such as a full-face type or a jet type.

C. Effects of the invention As described above, according to the invention, on the upper surface of the frame of the goggles, there are a pair of left and right protrusions that are formed so as to be able to abut the upper edge of the window of the helmet, respectively, and define a ventilation path between them. are provided close to both left and right ends of the frame, so even if the goggle frame approaches the upper edge of the helmet window due to relative movement between the goggles and the helmet due to vibrations, the upper edge will not touch the upper edge. By bringing the pair of left and right protrusions into contact with each other, a ventilation path can be secured between the upper edge and the top surface of the frame over a wide range in the left and right direction, and the driving wind that enters the helmet through the ventilation path is installed. Since it can be applied to the left and right sides of a person's forehead in a well-balanced manner over a wide area, a refreshing feeling can be obtained even in summer. In addition, the pair of left and right protrusions located near both left and right ends of the frame distributes the load received by contact with the upper edge of the window to the left and right, so that the upper side of the frame is
Since the parts near the left and right ends, which have comparatively high bending rigidity, can be stably and firmly received, it effectively prevents bending deformation of the upper center of the frame caused by the above loads, and by extension distortion of the goggle's windshield lens. can do.
