Goggles with Ventilation Structure

Abstract

Goggles with a ventilation structure have a frame, a lens, and a strap. The frame has multiple ventilation portions formed on an inner peripheral surface of the frame. The lens is mounted on the frame and has multiple through holes disposed along a peripheral edge of the lens and respectively communicating with the ventilation portions. The strap has two ends respectively connected to two opposite sides of the frame. Air outside the goggles can ventilate a space defined between the lens and a face of a wearer via the ventilation portions and the through holes, so as to dissipate heat accumulated in the space and to prevent the lens from fogging. Formation of the ventilation portions and the through holes does not require expanding a shape of the frame of the goggles. Thus, the goggles have compact volume and light weight and are comfortable for wearing.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0019] With reference to FIGS. 1 and 2, goggles with a ventilation structure in accordance with the present invention comprise a frame 10, a lens 20, a cushion pad 30, and a strap 40.

[0020] With further reference to FIGS. 3 and 5, the frame 10 has an upper frame portion 101, a lower frame portion 102, a rear peripheral surface, an inner peripheral surface, an inner peripheral recess 11, and multiple ventilation portions 14. The rear peripheral surface of the frame 10 faces toward a wearer of the goggles. The inner peripheral surface of the frame 10 surrounds a vision area AA of the goggles. The inner peripheral recess 11 is formed in and disposed along the inner peripheral surface of the frame 10, such that the frame 10 is divided into a front frame strip 12 and a rear frame strip 13.

[0021] The ventilation portions 14 are separately formed on the inner peripheral surface of the frame 10 and are disposed on the upper frame portion 101 and the lower frame portion 102 of the frame 10. Each of the ventilation portions 14 has a front ventilation hole 141 and a rear ventilation hole 142. The front ventilation hole 141 is formed through the front frame strip 12 of the frame 10. The rear ventilation hole 142 is formed through the rear frame strip 13 of the frame 10 and aligns with the front ventilation hole 141.

[0022] With further reference to FIG. 4, the lens 20 is mounted on the frame 10 and has a peripheral edge and multiple through holes 21. The peripheral edge of the lens 20 is inserted in the inner peripheral recess 11 of the frame 10, so as to mount the lens 20 on the frame 10. The through holes 21 are separately formed through the lens 20, are disposed along the peripheral edge of the lens 20, and respectively correspond in position to the ventilation portions 14 of the frame 10. Each of the through holes 21 communicates with the front ventilation hole 141 and the rear ventilation hole 142 of a corresponding one of the ventilation portions 14.

[0023] The cushion pad 30 is attached to the rear peripheral surface of the frame 10. When the wearer wears the goggles, the cushion pad 30 is fitted on a face of the wearer, so as to provide comfort to the wearer.

[0024] The strap 40 is elongated, is with an adjustable length, and has two ends respectively connected to two opposite sides of the frame 10. When the wearer wearers the goggles, the strap 40 pulls the frame 10, so the frame 10 stably abuts the face of the wearer. By adjusting the length of the strap 40, tightness of the strap 40 can be adjusted.

[0025] As shown in FIG. 4, with the ventilation portions 14 of the frame 10 and the through holes 21 of the lens 20, when the wearer wears the goggles, air outside an inner space defined between the lens 20 and the face of the wearer can flow into the space via the ventilation portions 14 that are disposed on the lower frame portion 102 of the frame 10 and the through holes 21 of the lens 20 that correspond in position to the ventilation portions 14 that are disposed on the lower frame portion 102. Then the air together with heat accumulated in the inner space flows out of the inner space via the ventilation portions 14 that are disposed on the upper frame portion 101 of the frame 10 and the through holes 21 of the lens 20 that correspond in position to the ventilation portions 14 that are disposed on the upper frame portion 101. Accordingly, the lens 20 can be prevented from fogging and vision of the wearer is not be blurred by fog.

[0026] The goggles as described have the following advantages. Since the ventilation portions 14 are formed on the inner peripheral surface of the frame 10 and the through holes 21 are disposed along the peripheral edge of the lens 20, formation of ventilation structure, i.e. the ventilation portions 14 and the through holes 21, does not require expanding a shape of the frame 10. Thus, the goggles have a compact volume and light weight and are comfortable for wearing.

[0027] Even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and features of the invention, the disclosure is illustrative only. Changes may be made in the details, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
