Description

    BACKGROUND OF THE INVENTION 1. Field of the Invention:
  • The present invention relates to a lampshade structure of a lamp, particularly to a magnetic lampshade frame structure with a convenient and secured assembly, and cost-effective and high-quality features.
  • 2. Brief Description of the Related Art:
  • Lamp is a common electric appliance used at home to provide necessary illuminations, create different atmospheres, and plays an important role in the interior design of modern homes. Various lamps such as ceiling lamps, floor lamps, wall lamps and table lamps are provided for different applications, and a lamp with a lampshade is usually used for creating indoor atmospheres. The lampshade can soften the light and adjust the brightness and color of the light. Conventional lampshades for a lamp are mainly divided into fixed lampshades and removable lampshades. However, the fixed lampshade has a large packaging volume which is unfavorable for transportation and storage, and incurs a higher cost or easier damage during the transportation process. Therefore, the removable lampshades are introduced to the market. For example, the removable lampshade as disclosed in R.O.C. Pat. No. M350672 provides a simple and easy way of installing and removing a lampshade frame and a hood connected by Velcro tapes, such that the lampshade frame and the hood can be packaged separately, and such removable lampshade can save packaging and transportation costs. Although such conventional lampshade structure can be assembled and disassembled, it still has the following drawbacks. For example, the upper frame and the lower frame are attached by the Velcro tapes, and they must have sufficient area for the tapes, so that that the upper frame and the lower frame will come with a larger volume and a heavier weight and result in a higher material cost. Furthermore, the lampshade assembled by the Velcro tapes gives a poor appearance. Obviously, the conventional lampshade frame structure requires improvement, and it is a main subject for related manufacturers and designers to provide an improved lampshade frame structure to overcome the aforementioned manufacturing and using drawbacks.
  • In view of the shortcomings and the weak structural design of the conventional the lampshade structure, the inventor of the present invention developed a magnetic lampshade frame assembly with the effects of saving the material, reducing the weight, and improving the quality of the lampshade frame.
  • SUMMARY OF THE INVENTION
  • Therefore, it is a primary objective of the present invention to provide a magnetic lampshade frame assembly capable of saving the material of the lamp, providing a quick and convenient way of assembling or disassembly a lampshade, and avoiding possible damages of a lampshade.
  • Another objective of the present invention is to provide a magnetic lampshade frame assembly, wherein a hood and a frame of the assembly can be combined more securely, and the texture of the assembly can be improved to enhance the added value of the lamp products.
  • To achieve the foregoing objectives, the technical measure taken by the present invention comprises: a frame device, including an upper frame and a lower frame; a hood device, including a hood, a connecting strip separately formed at upper and lower positions of an internal side of the hood, and an external side of the connecting strip being fixed to the hood, and an internal side of the connecting strip being magnetically coupled to the upper frame or the lower frame, and at least one of the connecting strip and the upper frame or at least one of the connecting strip and the lower frame is made of a magnetic material.
  • The technical characteristics and effects of the present invention will become apparent by the detailed description of the preferred embodiments together with the illustration of related drawings as follows:
