Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an external case for blinds used for windows of buildings.

[Problems to be solved by the prior art and the invention] In general, the external case of a blind used for a building window uses various parts such as a bracket, a case plate, a decorative edge, and a case angle, and is assembled by welding and screwing. They were twisted and pasted together to form a case. Therefore, assembling the external case has the drawbacks of poor workability and high material costs, resulting in high costs.

[Means for solving the problem] In view of the above-mentioned circumstances, the present invention was created with the aim of providing an external blind case that can eliminate these drawbacks. A unit case plate is formed by bending a plate material into a substantially U-shape in a plan view, and further bending both left and right ends of the plate material so as to extend outwardly to the left and right sides, and provided with mounting pieces.
A plurality of these unit case plates are arranged so that the upper and lower edges of adjacent unit case plates overlap with each other, and the mounting pieces of the unit case plates arranged so that these overlap sides overlap are screwed onto the side of the case body. It is characterized by having a structure in which it is stopped.

According to the present invention, with this structure, the unit case plates can be assembled from above so that the upper and lower edges are overlapped one after another, thereby simplifying the installation.

[Example] Next, an example of the present invention will be described based on the drawings. In the drawings, reference numeral 1 denotes a unit case plate, and the unit case plate 1 is formed by bending both left and right ends of a long and thin metal plate in the left-right direction into a substantially U-shape.
a, 1a are provided, and the left and right ends of these bent sides 1a are respectively bent outward in the left-right direction to form attachment pieces 1b, 1b. Further, a U-shaped upper edge connecting groove 1c is formed on the upper edge of the unit case plate 1, and a packing member 2 is filled in this upper edge connecting groove 1c. .
On the other hand, the lower edge of the unit case plate 1 is provided with a lower edge locking piece 1d bent inward so as to come into contact with and press against the packing member 2.

Reference numeral 3 denotes a sash for a window 4 installed in a building A, and a blind B is attached above the sash 3 on the outside. This blind B has a large number of blades 7 arranged in parallel, which are moved up and down by the rotation of a shaft 6 supported by a side plate 5 of a frame body of a blind case K, and whose angle is displaced. Transmission from
The rotation of the shaft 6 is transmitted through the universal joint 10 by the bevel gear of the transmission mechanism 8.

To assemble the case K, first, screws that pass through the screw holes 12 provided in the mounting piece 1b of the lowest unit case plate 1 are tightened and fixed to the stepped portion of the side plate 5 of the frame. Next, the packing member 2 is filled in the upper edge connecting groove 1c,
While firmly pressing the lower edge locking piece 1d of the next unit case plate 1 against this packing member 2, the mounting piece 1b is screwed onto the stepped portion of the side plate 5. Repeat this operation to attach the uppermost unit case plate 1, and press the packing member 2 in the upper edge connecting groove 1c with one side of the support plate 14, which is formed in a substantially O-shape. The other side is fixed to the top plate 13 of the eave 11 with screws or the like. This completes the installation of case K. In this embodiment, the case K5 is covered with an eaves 11, and the unit case plate 1 is secured to the eaves bottom plate (top plate) 13, but if there is no eaves 11, a top plate is provided, The uppermost end of the unit case plate 1 may be locked to the top plate.

In the embodiment of the present invention constructed as described above, a blind B consisting of a large number of blades 7 suspended in a vertically movable manner from a shaft 6 pivotally supported inside is provided outside the window 4, and the upper part of the window 4 is Attach the left and right mounting pieces 1b of the unit case plate 1 to the side steps of the blind case body provided in the upper part of the unit case plate 1 using screws. Mounted unit case plate 1
Apply the lower edge locking pieces 1d so as to overlap, and attach the attachment pieces 1b to the step part on the side of the frame.In this way, the uppermost unit case plate 1 is attached to the supporting plate 14 formed in an O-shape. Therefore, it is attached to the top plate 13 of the eaves 11 to constitute the case K. Therefore, the case K can be formed with an extremely simple structure simply by combining an appropriate number of unit case plates 1, the number of parts is significantly reduced, and the workability of the assembly work is also greatly improved. Therefore, it can be made at low cost.

Furthermore, the unit case plate 1 can be freely formed into an excellent design by processing the unit case plate 1 into irregularities using a roll forming machine or the like.

[Operation and Effect] In summary, since the present invention is constructed as described above, the upper and lower edges of adjacent unit case plates are arranged so as to overlap each other, and the mounting pieces formed on each of these unit case plates are The case is constructed by simply screwing and attaching the case to the frame. Therefore, the case is easy to assemble, and the unit case plates are arranged in order so that the upper and lower edges of adjacent ones overlap each other. Since the units are assembled by stacking them on top of each other, there is no need to manufacture the case in one piece each time according to the window opening dimensions as in the past, and it can be manufactured in advance in a planned manner, and the shape is simple. The price can be reduced from
