Description

[Detailed Description of the Invention] The present invention relates to a louver, and its purpose is to facilitate assembly.

1 to 4 show an embodiment of the present invention, which is a louver in which unit louvers 1 are connected by pins 2 and assembled into an arbitrary size. The unit louver 1 consists of a rectangular outer circumferential wall 5 divided into a grid-like shape by a central wall 3, and the cross-sectional shape of the central wall 3 has a maximum width portion 4 slightly below the upper end, and a maximum width portion 4 on the upper side. The width is gradually narrower toward the lower side, and the inside is hollow. The cross-sectional shape of the outer peripheral wall 5 is approximately 2 mm vertically from the center wall 3.
The outer peripheral walls 5 are formed in a divided shape, and the outer peripheral walls 5 located at opposite positions are shaped to engage with each other. That is, a protruding piece 6 whose tip end is inclined downward is formed on one side, and a receiving surface 7 that is inclined inwardly and with which the protruding piece 6 is engaged is recessed on the other side. Furthermore, grooves 8 into which the pins 2 are inserted are formed on the outer circumferential surface of the corners of the outer circumferential wall 5 and the joint portion with the central wall 3. The pin 2 has a substantially cross-shaped cross section with locking pieces 10 protruding from all sides, and a trapezoidal head 9 having a jaw 11 is formed at the tip of each locking piece 10. The fitting groove 8 for the pin 2 is formed astride the adjacent unit louvers 1.

A plurality of unit louvers 1 formed in this manner are connected adjacently to form a louver of a desired size. First, the unit louvers 1 are placed adjacent to each other, the projecting piece 6 is engaged with the receiving surface 7, and the unit louver 1 is
The pins 2 are fitted into the fitting grooves 8 formed at the joints of the adjacent unit louvers 1 to extend over them, and the locking pieces are closed. The jaw 11 of the head 9 formed at the tip of the louver 10 prevents the two unit louvers 1 from being separated and completes the connection.

The present invention is constructed as described above, and can be used, for example, as a louver of a lighting equipment, and louvers of various sizes can be assembled more easily than a unit louver, and a projecting piece and a receiving surface are provided for engagement. By positioning and temporarily fixing the unit louvers in phase with each other, and fitting a pin into a fitting groove formed across both unit louvers, the connection can be firmly completed. In this way, temporary fixing and pin fitting can be easily performed, and each unit louver can be reliably connected without being displaced.

Claims (1)

[Scope of utility model registration request] A louver configured by connecting a plurality of unit louvers, each unit louver forming a projecting piece and a receiving surface that engage with each other on opposite sides of an outer peripheral wall, and
A pin insertion groove is formed spanning adjacent unit louvers, and the pin is inserted into the insertion groove spanning both unit louvers while the adjacent unit louvers are in a temporarily fixed state in which the protruding pieces and the receiving surfaces are engaged with each other. A louver characterized in that the unit louvers are connected to each other by attaching them to each other.
