Description

Description: BACKGROUND OF THE INVENTION [0001] The present invention relates to a range hood cover made of a metal foil such as an aluminum foil formed by press molding or the like, and particularly to a size of the range hood. The present invention relates to a range hood cover whose length can be adjusted together. [0002] Conventionally, a range hood cover has been used in which a filter is attached to a central portion of a molded product formed by pressing an aluminum foil. This molded body has a predetermined size and shape defined by a press molding die or the like. [0003] However, range hoods are available in various sizes and shapes, and many types of sizes and shapes of covers have been required in accordance with these sizes. For this reason, there is a problem that a consumer needs to check the dimensions of his / her own range hood before purchasing it, and a producer needs to produce a large number of types in a small amount, which increases the production cost. Therefore, the appearance of a range hood cover whose length can be adjusted according to the size of the range hood has conventionally been desired. [0004] Therefore, an object of the present invention is to provide a range hood cover which can freely adjust a dimension in a predetermined direction as required. [0005] The range hood cover of the present invention has a flat plate shape, and has two opposite sides provided with curled portions formed by curling the outer edge in the plane. A range hood cover comprising a first divided body and a second divided body, wherein a filter is attached to a space defined by the two sides of the metal foil molded body having at least: The second divided body provided with a fixture only at both ends, and provided with the other of the fixtures at each edge winding portion of two opposing sides of the first divided body provided with one of the fixtures. The first divided body and the second divided body can be slid with each other by inserting the edge winding portions of each of the two opposite sides, and the direction perpendicular to the sliding direction can be adjusted. Engage with each other to prevent separation In addition, it is characterized in that the cross-sectional shape of each overlapping portion of the divided bodies at the time of sliding in the direction crossing the curled portion is substantially the same including the curled portion. [0006] The range hood cover of the present invention has a flat plate shape, and is provided on each of the two side edges of the first divided body with the opposite side edges of the second divided body. By inserting the part, the first divided body and the second divided body can be slid with each other and engaged with each other so as to prevent separation in a direction perpendicular to the sliding direction. ing. For this reason, in the sliding direction while maintaining a stable engagement state, each divided body can be freely adjusted in its entire length without detachment, and provided in each of the divided bodies in that state. It can be attached to the object to be attached using the attached attachment. Moreover, the divided bodies are formed such that the cross-sectional shape in the direction traversing the curled portion in each overlapping portion of the divided bodies at the time of sliding is substantially the same including the curled portion, and the divided bodies slide with each other. The range hood cover of the present invention is used because it is formed in a flat plate shape, and the two divided bodies can be slid with each other and are not separated. The depth of the range hood is not particularly required, and the length can be adjusted in the sliding direction according to the size and shape of the range hood without detaching each divided body. Therefore, in this state, the divided body can be easily attached to the attached body by using the attachments provided at each end of the divided body, and the usability is good. In addition, since the rim winding portion for sliding each divided body is formed in the same plane as the metal foil molded body, the sliding operation becomes smooth. Also, by partially overlapping two metal foils,
The molding can be performed by the same molding process as in the past, and no extra molding process is required. Furthermore, since the dimensions can be increased by sliding after molding, even when the range hood cover has a large dimension when it is slid and extended, it can be molded with a mold having a smaller dimension. [0008] Further, since it can be slid into a small size and shape, it can be handled compactly in the distribution process. As a result, there are many merits such as saving of transportation costs and the like, and reduction of the space for display. Furthermore, since the cross-sectional shape in the direction crossing the curled portion in each overlapping portion of the divided bodies at the time of sliding is substantially the same including the curled portion, 1
It is also possible to separately mold and combine the divided bodies with one press molding die.
