Description

[Detailed explanation of the idea] This invention relates to a louver door device.

Conventionally, there have been louver doors 3 and 4 as shown in FIGS. 2 and 3 as a louver door 2 attached to the front opening of a large air-conditioning storage box 1 as shown in FIG. The louver door 3 in FIG. 2 has a lower louver door body 6 fitted into the lower opening of the door frame 5, and is rotatable about a pin 7 protruding from the inner peripheral surface of the door frame at the upper opening of the door frame 5. The upper louver door body 8 is attached to the upper louver door body 8. However, with the structure in which the upper louver door body 8 is pivotally supported by the pin 7, there is a problem that when the opening width of the storage box 1 becomes large, the center portion of the upper louver door body 8 is bent, making it impossible to support the upper louver door body 8 in rotation. It had

On the other hand, in the louver door 4 shown in Fig. 3, the center of the vertical frame member of the door frame 9 is pivoted with an embedded hinge 10 so that it can be folded forward or raised freely, but since the door frame 9 is separated at the center, the door When the frame 9 is stood up, the central joint part of the door frame 9 stands out and the aesthetic appearance is impaired.

Furthermore, both of these louver doors 3 and 4 had the disadvantage of poor productivity because it was necessary to counterbore holes in the door frames 5 and 9 in order to attach the pins 7 and the embedded hinges 10.

Therefore, the purpose of this invention is to create a louver that can accommodate large width dimensions, has an excellent design, improves productivity, and also allows for easy and reliable fixation of the hinge and prevents the hinge from bending backwards. It is an object of the present invention to provide a door device.

An embodiment of this invention will be described with reference to FIGS. 4 to 8. In other words, this louver door device is
As shown in FIGS. 4 and 5, the lower vertical bar 11 and the upper vertical bar 12 are connected by a hinge 13 so as to be flexible and extendable to form a wing support vertical bar 14, and the lower vertical bar 11 and the upper vertical bar Multiple blades 1 on each crosspiece 12
5 are orthogonally connected to form a lower louver door body 16 and an upper louver door body 17, and the lower louver door body 16 is fitted into the lower part of the opening of the door frame 18, and the upper louver door body 17 is connected to the upper part of the opening of the door frame 18. It is fitted so that it can be moved forward.

As shown in FIG. 6, the hinge 13 has a support shaft 13a.
It consists of an upper piece 13b and a lower piece 13c that rotate about a fulcrum, and rail mounting protrusions 13d and 13e are provided projecting from the tips of these upper pieces 13b and lower pieces 13c.
As shown in FIG. 5, a rivet 1 is attached to the lower part of the groove-shaped upper vertical bar 12 on the projecting piece 13d of the upper piece 13b.
9, and the upper part of the groove-shaped lower vertical bar 11 is similarly connected to the protruding piece 13e of the lower piece 13c with a rivet 20.

As shown in FIGS. 7 and 8, the lower louver door body 16 is constructed by orthogonally connecting a plurality of wings 15 to the front surface of the web of the lower vertical crosspiece 11, and the upper louver door body 17 is also constructed by connecting a plurality of wings 15 orthogonally to the front surface of the web of the lower vertical crosspiece 11. Multiple feather boards 15 between the crosspieces 12
These two louver door bodies 16 and 17 constitute a louver door body 21 (FIG. 4).

The door frame 18 has a decorative inner frame 22 fitted to the inner peripheral surface of its opening, and L-shaped pieces 23 and 24 for attaching the door frame are provided protruding from the back surfaces of the upper and lower frame members of the door frame 18.

To attach the louver door body 21 to the door frame 18, as shown in FIG.
5 and the decorative inner frame 22 are connected by a connecting member 25, and the lower end of the lower vertical bar 11 is fixed to the decorative inner frame 22. In addition, a support bar 26 is provided on the back side of the upper frame material of the door frame 18.
and attach a magnetic chuck 27 to its lower end surface.
At the same time, as shown in FIG. 7, attach the magnetic catch plate 28 to the back side of the uppermost wing plate 15, and use the magnetic chuck 27 to attract the magnetic catch plate 28 to raise the upper louver door body 17. It is possible to maintain the posture. Furthermore, as shown in FIG. 8, chain supports 29 and 30 are attached to the side surface of the support bar 26 and the back surface of the uppermost wing plate 15, respectively, and a chain 31 is strung between the two, and as shown in FIG. When the louver door body 17 is pulled down toward the front, the chain 31 restricts the front side of the upper louver door body 17 to a predetermined angle.

To attach the door frame 18, as shown in FIG. L for installing the door frame in the groove 36 of
This is done by fitting the shaped pieces 24 together.

As a result of this configuration, as shown in FIG. 4, the upper louver door body 17 can be opened by strongly pulling it down toward the front, and conversely, by pushing the upper louver door body 17, the plate 28 can be opened using the magnetic chuck 27. Can be closed by adsorption. In addition, the upper vertical bar 12 and the lower vertical bar 11 are pivotally connected by a hinge 13, and the upper louver door body 17 can be folded forward or raised freely using the hinge 13 as a fulcrum, so even if the door width becomes wider, the upper louver The door body 17 can be rotatably supported. Furthermore, since the door frame 18 is not divided at the center, there is no joint in the door frame 18, resulting in an excellent design. In addition, counterbore holes for attaching the pin 7 (FIG. 2) and the hinge 10 (FIG. 3) to the door frame 18 are not required, so productivity can be improved. Moreover, since the door frame 18 can be firmly fixed to the air conditioning storage box 32, it fits well.

As described above, in the louver door device of this invention, a plurality of blades are orthogonally connected to the lower vertical bar and the upper vertical bar to form the lower louver door body and the upper louver door body, and the lower vertical bar... A louver door body in which the upper part and the lower part of the upper vertical bar are connected by a hinge so as to be bendable and extensible, and the lower louver door body is fitted to the lower part of the own opening, and the upper louver door body is placed forward to the upper part of the own opening. A door frame that is fitted so that it can be collapsed, and an engaging member and an engaged member that can be freely engaged and disengaged from each other are respectively fixed to the upper louver door body and the door frame, and when the upper louver door body is erected, they do not touch each other. Since it is provided with a holding means that engages with the upper louver door body and holds the upper louver door body in an upright position, it can be used even with large width items, has an excellent design, and can improve productivity. Further, the structure of the hinge is such that mounting protrusions are provided on both side edges of the upper and lower pieces that are rotatably connected to each other, and the mounting protrusions of the upper piece are attached to the groove-shaped mounting protrusions. It is fixed to the inner surfaces of both flanges of the upper vertical bar, and both mounting protrusions of the lower piece are fixed to the inner surfaces of both flanges of the groove-shaped lower vertical bar. Therefore, the hinge can be easily and reliably fixed to the groove-shaped upper and lower vertical bars. Moreover, since there is a mounting protrusion, the rigidity of the upper and lower pieces is increased, and the reverse bending of the butterfly plate is reliably prevented.
Therefore, there is an effect that reverse bending of the upper louver door body and the lower louver door body does not occur.
