Abstract

A flexible sheet includes a collar portion and a belt portion, and both ends of the belt portion are connected to both ends of the collar portion via a basic folding line, and the belt portion is connected from the folding line. Provided is a sun visor in which a head size can be adjusted in a sun visor that is reversed and is put on the head using a space generated between a collar portion and a belt portion. In a sheet state, the collar part 2 and the belt part 3 are in contact with each other with a notch from the inner end of the foundation folds 5a, 5b, and the size adjustment is parallel to the foundation crease during this time. This is achieved by providing the folding lines 6a and 6b near the center of the collar portion. [Selection] Figure 2

Description

  The present invention relates to a sun visor that can be easily assembled by simply punching out a single flexible sheet, which is used to protect the eyes from sunlight by wearing it on the head.

A single sheet made of polypropylene sheet or paper sheet is divided into a collar part and a belt part by cutting both ends that do not reach the edge of the sheet in a straight line and a substantially arc shape in the center part. Various sun visors have been proposed that have a crease at the edge of the sheet and reverse the belt portion from the crease to create a space between the collar portion and the belt portion and cover the head (Patent Documents 1 and 2). . However, a common disadvantage is that the length of the belt portion is constant, so that the head size cannot be adjusted, and it has to be made with the average head size. That is, in these methods, the head size is determined by the cut length of the collar side and the length of the belt portion, and only one type of head size can be produced from one sunburner.

  The problem to be solved by the present invention is to make it possible to adjust the head size even in a simple assembling sun visor made by punching from a single sheet as described above.

  The first problem-solving means has a collar portion and a belt portion in a flexible sheet, and both ends of the belt portion are connected to both ends of the collar portion via a basic folding line. In the sun visor that covers the head using the space generated between the collar part and the belt part by reversing the belt part from the line, the collar part has a fold line for size adjustment parallel to the crease line. The sun visor is characterized.

  The second problem solving means is that, in the sheet state, at least part of the length from the inner end of the basic fold line is such that the collar part and the belt part are in contact with each other through a notch. Further, the sun visor described in the first problem solving means is characterized in that a locking cut having an incision side closer to the center of the collar portion as an edge is provided on the collar portion side.

  As shown in Patent Documents 1 and 2, both ends of the collar part and the belt part are connected via a crease, and in the method of covering the head by the space generated by inverting the belt part from the crease, the head is conventionally Although the size could not be adjusted, the head size could be easily adjusted with a simple sunburner with one sheet punched out according to the present invention.

  FIG. 1 is a development view of the sun visor of the present invention. In the 0.5 mm thick titanium pigment-filled polypropylene sheet 1, the collar portion 2 and the belt portion 3 are connected by the basic folding lines 5 a and 5 b, and the portions between the basic folding lines 5 a and 5 b at the ends 9 a and 9 b are cut into 8 a and 8 b, respectively. The collar portion and the belt portion are in contact with each other through 4a and 4b. The space N surrounded by the belt portion edge 4c and the collar portion edge 5 has no sheet. In this embodiment, the N portion is cut off, but the belt edge 4c may be folded or left as it is without affecting the essence of the present invention.

  In FIG. 1, size adjustment folding lines 6a and 6b parallel to the basic folding line are provided on the flange part side in the notches 4a and 4b, closer to the center of the collar part than the basic folding lines 5a and 5b. It shows that the locking cuts 7a and 7b are provided in the notches 4a and 4b sections on the inner side near the center.

  FIG. 2 is a perspective view showing a state in which the belt portion 3 is pulled up from the state shown in FIG. This state has the largest head size.

  FIG. 3 is a perspective view showing a state in which the size adjusting folds 6a and 6b are bent from the state shown in FIG. 2 and the side 4c of the belt portion 3 is inserted into the locking cuts 7a and 7b. The head size is reduced by bending from the size adjusting crease, and this state is fixed by inserting the belt portion into the locking cut.
