Abstract
An improved blade structure for ceiling fan includes a plurality of brackets and a blade element. The brackets are made of wood, bamboo, metal, plastic or the like. The blade element is made of paper, cloth, plastics, thin metal sheet, rubber, synthetic paper or the like. The blade element is bonded to the brackets by adhering, clamping, nailing, snapping, threading, screwing, meshing, stitching, gluing, laminating, riveting or the like to form a foldable blade structure.
Description
- This invention relates to an improved blade structure for ceiling fan and particularly a blade structure for ceiling fan that is foldable.
- Conventional blades for ceiling fan are usually made by integral forming. The blade has a relatively great thickness. It consumes more materials and is heavier. When in use, it also adds more workload for the motor and consumes more electricity power, and tends to lower the rotation speed and reduces air ventilation volume. There are still rooms for improvement.
- In view of the foregoing disadvantages, it is therefore an object of this invention to provide an improved blade structure for ceiling fan that comprises a plurality of brackets and at least one blade element bonded to the brackets to form a foldable structure. The blade structure may be fastened to a blade frame or an impeller. The blade structure thus formed can greatly reduce costs, size and weight, and may be folded to a smaller size to facilitate transportation. When in use, it also can reduce workload to the motor and increase motor rotation.
- The invention, as well as its many advantages, may be further understood by the following detailed description and drawings. The drawings are only to serve for reference and illustrative purpose, and do not intend to limit the scope of the present invention.
- FIG. 1 is a perspective view of this invention
- FIG. 2 is an exploded view of this invention.
- FIG. 3 is a top view of this invention assembled to a ceiling fan.
- FIG. 4 is a top view of this invention at an extended state.
- FIG. 5 is a top view of this invention at a folded state.
- FIGS. 6A, 6B and6C are schematic views of other embodiments of this invention.
- Referring to FIGS. 1 and 2, the blade structure according to this invention includes a plurality of
brackets 10 and at least oneblade element 11. Thebrackets 10 are made of wood, bamboo, metal (such as aluminum, zinc, steel or the like), plastics, or the like. Theblade element 11 is made of paper, cloth, plastics, thin metal sheet, rubber, synthetic paper, or the like. Each of thebrackets 10 has a selected length and may be formed in a shape desired (such as the ones shown in FIGS. 6A and 6B). Theblade element 11 is extended and bonded to thebrackets 10. The outer edge of theblade element 11 may be bent to form a coveringsection 14 to shroud the outer end of thebrackets 10. Thebrackets 10 andblade element 11 may be bonded together by adhering, clamping, nailing, snapping, threading, screwing, meshing, stitching, gluing, laminating, riveting, or any other fastening means known in the art to form a foldable structure (shown in FIG. 5). Thebrackets 10 support theblade element 10 like a sail or kite, and may be formed in a polygon, or in a solid or hollow structure. - FIGS. 1, 2 and3 illustrate detailed structure of this invention. The
brackets 10 have respectively one end fastened to a blade frame 12 (or impeller) by means of afastener 13. The outmost bracket 10 (according to rotational direction) is fixed toblade frame 12 by thefastener 13 at one end thereof. Theremaining brackets 10 are pivotally engaged with theblade frame 12 at one end thereof by means of thefasteners 13. Hence when the fan rotates, thepivotal brackets 10 will swing about thefasteners 13 and be folded or extended selectively. Referring to FIG. 5, when the blade structure rotates counterclockwise (or clockwise), the leftmost (or rightmost)bracket 10 will remain fixedly mounted on theblade frame 12 without moving, butother brackets 10 pivotally engaged with theblade frame 12 will swing to the right (or left) side for controlling the extension of the blade element 11 (as shown in FIG. 4) to form a larger area whereby to achieve air ventilation purpose through the driving of the motor. FIG. 6C shows that thebrackets 10 may also be stacked at one end to engage with theblade frame 12 by means of onefastener 13. - Through this invention, the brackets and blade element may be organized and assembled to a wide variety of forms. It is easy to assemble and install by users in a DIY fashion. It can greatly reduce cost, shrink size, reduce weight, and be folded to a smaller size for package (as shown in FIG. 5) to lower transportation cost. When in use, it can reduce motor workload and consequently reduce consumption of silicon steel and coils used in the motor. Because of its lighter weight, motor rotation efficiency will also be improved.
- In summary, this invention provides an improved blade structure which effectively resolves the problems and disadvantages happened to conventional ceiling fans such as integrally formed blades, thicker blade element, consuming more materials, weight heavier, and added motor workload.
- It may thus be seen that the objects of the present invention set forth herein, as well as those made apparent from the foregoing description, are efficiently attained. While the preferred embodiments of the invention have been set forth for purpose of disclosure, it would be obvious to those skilled in the art that various other changes and modifications can be made according to the embodiments. Accordingly, the appended claims are intended to cover all embodiments which do not depart from the spirit and scope of the invention.
