Description

DESCRIPTION

Fan

TECHNICAL SECTOR

The present application refers to a fan with folding rods, so that when it is in its closed position it can be folded, thus reducing its size.

STATE OF THE ART

Multiple types of fans made of various materials and with various configurations are known which, in their closed position, have a longitudinal dimension equivalent to the length of the rods.

This has the drawback of being cumbersome to store and transport, for which reason the invention provides a folding fan that aims to overcome said drawback.

The applicant does not know of any fan similar to the invention.

BRIEF EXPLANATION OF THE INVENTION

The invention consists of a fan according to the first claim. Its different variants solve the problems outlined.

The fan of the invention is made up of a series of main rods all joined together at the same end by means of a pin on the handle or another fixing element that allows them to rotate around said element.

Each main rod is divided into two parts, a lower or handle rod and an upper fan country fixing rod.

At the end opposite the nail of the handle, each of the lower rods is hinged to an upper rod preferably of the same length as the lower rod. Each pair of lower and upper rods is articulated by means of a pin of the rod or fixing element that allows them to rotate around said element. All the pins on the rods are coaxial when the fan is retracted.

Each pair of lower and upper rods has a relative articulated motion of approximately 180 °, allowing them to fold substantially parallel to one another and extend into a straight line. To do this, the pins of the rods are located to one side of the longitudinal axis of the main rod to allow these positions.

The rods are of a suitable lightweight rigid or semi-rigid material, such as wood, mother-of-pearl, plastic, cardboard and the like.

Preferably, the lower rod has a triangular shape.

The fan country can be made of cloth, paper or other suitable lightweight material and is attached to the upper ribs in the conventional way.

In use, each pair of upper and lower rods is aligned. To carry out the folding of the fan of the invention, first the fan is closed in the conventional way and then, once all the pairs of lower and upper rods are superimposed, all the upper rods are rotated at the same time in the same direction of rotation, until they are practically parallel to the lower rods.

For the deployment of the fan of the invention, the previous steps are carried out in the reverse order, and then the fan can be opened for use. To ensure strength, it is preferable that the upper rods snap into place (temporary deformation of a retaining element) on the lower rods, or vice versa.

Other variants can be seen in the rest of the report.

DESCRIPTION OF THE FIGURES

For a better understanding of the invention, the following figures are included.

Figure 1: Schematic general view, in plan, of an embodiment with the fan of the invention unfolded.

Figure 2: Schematic representation, in plan, of the fan of the invention folded in figure 1.

MODES OF EMBODIMENT OF THE INVENTION

Next, an embodiment of the invention will be briefly described, as an illustrative and non-limiting example thereof.

The figures show an example of an embodiment of a fan with a series of main rods (1) joined by a pin in the handle (2) and with a country at the other end.

Figure 1 shows an embodiment that comprises a main rod (1) formed by a lower rod (1a) and an upper rod (1b) articulated with each other.

The lower rods (1a) are all articulated with each other by means of the handle pin (2).

At the end opposite the handle pin (2), each lower rod (1a) is hinged to each upper rod (1b) by the rod pin (3).

In figure 1, the open position of the fan is observed, where each pair of lower and upper rods (1a, 1b) is deployed forming a straight line. This is the fan use situation.

In figure 2, the folded position of the fan of the invention is shown schematically. It can be seen that to obtain this position, all the main rods (1) must start from a position in which they are superimposed on each other (closed position of a conventional fan). From this position, all the upper rods (1b) are rotated at the same time around the rod pin (3) to a position where the upper rods (1b) are substantially horizontal to the lower rods (1a).

In order to carry out the aforementioned relative movement and obtain the fully folded and unfolded positions, the pin of the rod (3) can be misaligned with respect to the axis of the rods (1a, 1b).

In the embodiment shown, the end of the lower rod (1a) in which the rod pin (3) is placed is shaped as two circles whose centers are on a line perpendicular to the axis of the main rod (1). Both centers are displaced approximately the thickness of the main rod (1), each center being located on either side of it. Both circles are slightly overlapping.

In this embodiment, one of the circles will have the pin (3) of the rod located in its center. The other circle will have a cutout coinciding with the axis of the rod (1a) and of the same thickness. This allows that, when unfolding the fan and aligning the lower rod (1a) with the upper rod (1b), they coincide and remain in this position, pinched by the circles.

Claims (3)
