1. Field of the Invention
The present invention relates to a sun visor, and more particularly to a sun visor having two folded head bands to form a frustum-shaped head encircling device, and to comfortably and firmly attach the sun visor onto heads of users.
2. Description of the Prior Art
Various kinds of typical sun visors have been developed and include a head covering or cap provided for attaching onto heads of users.
For example, U.S. Pat. No. 1,718,867 to Mahlmann discloses one of the typical sun visors comprising a head covering or cap provided for attaching onto the heads of the users, and an eye shade attached to the head covering or cap for shielding eyes from sun shines. However, the head covering or cap is made of open mesh fabric and may not be easily made by users themselves.
U.S. Pat. No. 4,262,367 to Herrin discloses another typical sun visor comprising an elastic string having one end attached to a visor portion, and a retainer attached to the other end thereof, for engaging with the visor portion, and for attaching the sun visor onto the heads of the users. The elastic string should be made of resilient or elastomeric materials that is different from that of the visor portion.
U.S. Pat. No. 4,556,993 to Okamura, Sr. discloses a further typical sun visor comprising a head encircling band attached to a visor, for attaching the sun visor onto the heads of the users. The head encircling band should also be made of resilient materials that is different from that of the visor portion.
U.S. Pat. No. 4,670,910 to Rosasco discloses a still further typical sun visor comprising two head band portions extended from a center portion and having slits engageable with each other to provide an adjustable fit to the users' head size. However, the head band portions are directly extended from the center portion and sun visor and may form a cylindrical structure that may not be suitably or comfortably attached onto the heads of the users.
U.S. Pat. No. 5,010,590 to Haber et al. discloses a still further typical sun visor also comprising two head band portions extended from a center bill portion and having notched ends engageable with each other to provide an adjustable fit to the users' head size. However, similarly, the head band portions are directly extended from the center bill portion and may also form a cylindrical structure that may not be suitably or comfortably attached onto the heads of the users.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional sun visors.
The primary objective of the present invention is to provide a sun visor including two folded head bands to form a frustum-shaped head encircling device, and to comfortably and firmly attach the sun visor onto heads of users.
In accordance with one aspect of the invention, there is provided a sun visor comprising a central visor portion, and two head band portions extended from the central visor portion and each having at least one coupling member provided therein and engageable with each other, to couple the head band portions together and to form a head encircling device and to adjustably attach the sun visor onto a head of a user, and a first and at least one second folding lines provided and formed between the center visor portion and each of the head band portions, and inclined relative to each other, to form a superposed portion between the center visor portion and each of the head band portions after the head band portions are folded relative to the center visor portion along the folding lines, and to form a frustum-shaped structure, but not a cylindrical-shaped structure for the head encircling device, and thus to adjustably fit to the users' head size.
The coupling member includes a slot or a catch formed in the head band portions respectively. It is preferable that the head band portions are perpendicular to the central visor portion respectively.
The first folding line is preferably perpendicular to the head band portions respectively, and the second folding line is inclined relative to the first folding line and the head band portions respectively.
Further objectives and advantages of the present invention will become apparent from a careful reading of the detailed description provided hereinbelow, with appropriate reference to the accompanying drawings.
Referring to the drawings, and initially to
Two or more folding lines 16, 17 are provided or formed between the center visor portion 11 and each of the head band portions 12, 13, and are inclined relative to each other. For example, the head band portions 12, 13 may first be folded relative to the center visor portion 11 along the folding line 17 (
Alternatively, the head band portions 12, 13 may first be folded relative to the center visor portion 11 along the folding line 16 and then folded along the other folding line 17, to form the folded and/or superposed portion 18 between the center visor portion 11 and each of the head band portions 12, 13.
After the head band portions 12, 13 are folded relative to the center visor portion 11 along the folding lines 16, 17 to form the folded and/or superposed portion 18 between the center visor portion 11 and the respective head band portions 12, 13, and due to the inclination of the two folding lines 16, 17 relative to each other, a head encircling device 15 may be formed (
It is preferable that one of the folding lines 16 is perpendicular to the respective head band portions 12, 13, or perpendicular to the longitudinal axis 90 (
