Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an attachment/detachment structure for an outlet blade body for removably fixing the blade body to a main body.

[Prior Art] In conventional blower outlet blades that can be attached and removed from the main body, a large number of blades are fixed to a frame, and the blades and frame are integrated. There is.

When attaching and detaching this blade body to the main body,
Attachment and removal were done by tightening or removing numerous screws, etc.

In response to this problem, an air conditioning vent device as shown in Japanese Utility Model Application Laid-Open No. 63-29042 has been proposed, which suggests a structure in which guide vanes can be mounted using coil springs.

[Problem to be solved by the invention] However, in the device structure disclosed in the above publication,
One end of the coil spring is fixed inside the air terminal box, and the other end is fixed to the guide vane, so when installing the guide vane, there is a person holding it and a person holding the guide vane. Two workers are required, including one to grasp the other end and pull it down to attach it to the guide vane, which not only increases labor costs, but also pulls down the coil spring to resist the spring force. The work of attaching it to the guide vane side while grasping the end of the guide blade is not something that can be done easily with one touch, but requires several attempts to obtain the set state, so the installation process is time-consuming. , it was inefficient.

In addition, since it is simply held in the upwardly pulled state by the tensile force of the coil spring, when a force is applied to pull the guide vane down, it elastically separates from the inside of the air terminal box, and in particular, it easily separates due to vibrations such as earthquakes. It was easy to do, but there were problems in terms of safety.

The present invention was developed in view of the above-mentioned problems, and its purpose is to allow a single worker to easily attach the blade to the main body with a single touch, greatly improving the work efficiency of attaching and detaching, and Another object of the present invention is to provide a structure for attaching and detaching an outlet blade body that also ensures safety during use.

[Means for Solving the Problems] In order to achieve the above object, the present invention includes a frame 3 provided on the main body 1 side, a blade 4 that can be removably fitted into the frame 3, This blade body 4 has:
When this is installed in the frame 3, a protrusion 6 is provided which is engaged with the frame so that it does not protrude at least from the inside of the frame. It is constructed of a structure for attaching and detaching an air outlet blade body, which is provided with a biasing member 7 that biases in the direction of protrusion from the frame body 3.

[Function] According to the attachment/detachment structure of the air outlet blade body of the present invention, after one end of the blade body is inserted and pushed into the frame body on the main body side, the other end side is further inserted into the frame body by the spring force of the elastic material. If the protrusion on the blade body side is engaged with the frame body on the main body side by pushing it in while resisting, the blade body will be fixed to the main body by the spring force of the elastic material.

The blade body can be removed by reversing the above procedure.

[Example] Hereinafter, with reference to the drawings, the features of the attachment/detachment structure of the outlet blade body of the present invention will be specifically explained based on an example.

FIG. 1 is a side cross-sectional view of the outlet including the attachment/detachment structure of the outlet blade in this embodiment.

The main body 1 is formed in a box shape and has an appropriate volume to maintain rectifying performance. A neck part 2 for connecting to a duct is formed at the upper part of the main body 1, and a frame body 3 is riveted around the lower part thereof. The cross section of this frame 3 is approximately L.
It has a shape that protrudes inward. and,
A space S having at least the height of the main body 1 is formed in the upper part of the frame 3.

The blade body 4 is inserted into a quadrilateral portion defined by the inner edge of the frame body 3 and attached to the main body 1 side.

Here, as shown in FIG. 2, the blade body 4 and the frame body 3 forming the above-mentioned quadrilateral portion are constructed so as to minimize the gap G therebetween from a design point of view.
Therefore, as shown in FIG. 3, the two opposing sides of the blade body 4 are bent inward, and the reinforcement structure 5
have. And the remaining two sides are the blade body 4
The protrusion 6 is formed by bending outward from the middle part of the thickness. In this embodiment, the protruding portion 6 is constituted by a flange formed by integrally bending the blade body 4. This flange engages with the inner edge of the frame 3 so that the blade 4 can be attached to the main body 1. When the blade body 4 is installed in the frame body 3, it is locked to the frame body 3 and at least the force in the direction of protruding from the inside of the frame body, that is, in the direction of popping out downward, is locked so that it does not protrude. That's what I do. Further, the thickness of the reinforcing structure part 5 is formed to be thicker than the flange part, so that when the blade body 4 is attached to the frame body 3, the reinforcing structure part 5 is positioned above the flange part.

The main body 1 is provided with a biasing member 7 for pressing and fixing the blade body 4 formed in this way to the inner wall of the frame body 3. This biasing member 7 always biases the blade body 4 in the direction of protruding from the frame body 3, and therefore, as described later, resists this biasing force and pushes the blade body 4 inside the frame body 3. The blade body 4 can be attached by a one-touch operation by inserting it into the frame and locking the flange portion as the protruding portion 6 to the inner edge of the frame by one worker. The blade body 4 is always urged in the direction of protruding from the inside of the frame body 3 to the outside, and this urging force is received by the protruding portion 6 to maintain the locked state. 3 is firmly fitted, and can be reliably locked inside. In this example,
The biasing member 7 is formed from a leaf spring. The leaf springs are provided on both sides of the ceiling plate 8 on the main body 1 side, which faces the side of the blade body 4 having the reinforcing structure portion 5 .

As shown in FIG. 4, this leaf spring has a substantially mountain-like shape when viewed from the side, and its central portion is riveted to the ceiling plate 8 of the main body 1. Both ends of the leaf spring are curled so that they can be pressed without damaging the reinforcing structure 5 of the blade body 4. The spring force of this leaf spring can be adjusted by adjusting the opening degree of the mountain-shaped wing portions.

The curled portion 9 of the leaf spring also touches the inner edge of the frame 3 and is locked therein.

In the figure, 10 is a mounting bracket for the outlet body 1.

Next, the procedure for attaching the blade body 4 will be explained.

As shown in FIG. 5, first, one side of the blade body 4 with the flange is inserted into the inside of the frame 3, and shifted in the direction in which the flange protrudes (FIG. 5A). Next, the other side of the blade body 4 is pushed in so that the collar does not touch the frame body 3. At this time, the reinforcing structure portion 5 of the blade body 4 comes into contact with the curled portion 9 of the leaf spring, and the blade body 4 is in a state of being pressed by the leaf spring. Next, in this state, the blade body 4 is shifted in the direction of arrow A, and the blade body 4 is set in the frame body 3 after fine adjustment of its position (FIG. 2B).
In this state, the reinforcing structure part 5 of the blade body 4 is pressed by the curl part 9 of the leaf spring, the collar part engages with the inner edge of the frame body 3, and the blade body 4 is fixed to the main body 1. It's getting warmer (Figure C).

When removing the blade body 4 from the main body 1, follow the procedure in reverse to the above.

In the above embodiment, a leaf spring is used as the elastic material, but the present invention is not limited to this. Any member that can press and fix the body 4 to the main body 1 may be used.

Furthermore, the elastic material does not necessarily have to press against the reinforcing structure 5 of the blade body 4, but may have a structure that presses against the flange.

Furthermore, although the structure of the flange integrally molded with the blade body 4 as a protrusion has been described, it may be a separate structure such as a bracket.

[Effects of the invention] As explained above, according to the detachable structure of the air outlet blade of the present invention, the blade and the main body can be easily attached by simply inserting the blade into the frame on the main body side. It can be attached and detached. In particular, only one person is required to install it, so labor costs are low, and
Since the installation process is as simple as pushing in and releasing, it can be installed with a single touch, reducing work time and ensuring that the biasing member and the protruding part are securely locked during use. This has the effect of maintaining safety by ensuring that.
