[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to an air outlet suitable for spot air-conditioning in a factory, air-conditioning suitable for air conditioning in a bowling alley, hall, gymnasium, etc.

[0002]

[Prior art]

 Conventionally, it is composed of an air blowing member that opens toward the inside of a room and a mounting member that rotatably and tiltably supports the air blowing member, and the air blowing member includes a cylindrical air blowing portion and a hollow hemispherical portion continuous with the tubular air blowing portion. The mounting member comprises a strip ring surrounding the diametrical outer surface of the hollow hemispherical portion of the air blowing member and a mounting portion connected to the strip ring, and the hollow hemispherical portion on the inner surface of the strip ring. It is known to have an air outlet with a felt ring attached to it.

[0003]

[Problems to be solved by the device]

 The air blowing member of the air outlet is supported by a mounting member via a felt ring, and this felt ring is used to maintain airtightness between the air blowing member and the mounting member. Since the air blowing member of the air outlet easily moves with a slight force, there is a problem that if the air blowing member is adjusted to a desired angle and some force is applied, the member easily moves. If the felt ring is made thick to increase the contact pressure to the air blowing member, the air blowing member can be made difficult to move, but it is difficult to set the contact pressure to an appropriate value.

The present invention solves the above-mentioned problems of the conventional air outlets, allows the air outlet portion of the air outlet member to be easily rotated and tilted to a desired angle, and its position can be set with a slight force after setting. It is an object to obtain an air outlet that can be fixed so that it does not move and that the force for rotating and tilting the air outlet member can be easily adjusted to an appropriate value.

[0005]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention comprises an air blowing member that opens toward the inside of a room and a mounting member that supports the air blowing member so as to be rotatable and tiltable, and the air blowing member includes an air blowing portion and an air blowing portion. The attachment member comprises a strip-shaped ring surrounding the diametrical outer surface of the hollow hemispherical portion of the air blowing member and a attachment portion connected to the strip-shaped ring. The inner surface of the air spring is attached with a leaf spring and the airtight felt ring that comes into contact with the outer surface of the hollow hemispherical portion of the air blowing member, and both ends of the leaf spring are attached to them. It is characterized in that it is pressed against the hollow hemispherical portion via a flexible sheet piece. The air blowing member may have a flocked layer on the outer surface.

According to the present invention, an intermediate portion of one or more leaf springs is fixed to an inner surface of a band-shaped ring of a mounting member, and both ends of the leaf spring are attached to a hollow hemispherical portion of an air blowing member via a flexible sheet piece. Since they are pressed against each other, the air blowing portion of the air blowing member can be easily rotated and tilted to a desired angle, and after being set, it can be fixed so as not to move from that position with a slight force. The rotational tilting force of the air blowing member can be easily adjusted by adjusting the spring pressure of the leaf spring and / or by changing the number of leaf springs. When the flocked layer is provided on the outer surface of the air blowing member, the formation of dew condensation on the outer surface is prevented.

[0007]

[Embodiment of device]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

1, 2, and 3 show an example of the air outlet of the present invention.

In the drawings, 1 is an air blowing member, and 2 is a mounting member.

The air blowing member 1 is made of a thin aluminum plate, and is composed of a cylindrical air blowing portion 1a and a hollow hemispherical portion 1b connected to the air blowing portion 1a, and the surface thereof is anodized. The mounting member 2 comprises a strip-shaped ring 2a surrounding the diametrical outer surface of the hollow hemispherical portion 1b of the air blowing member 1 and a mounting portion 2b integrally connected to the strip-shaped ring 2a. It is composed of an upper ring 2a ₁ bent inward and a lower ring 2a ₂ bent inward at the lower end, and is fitted with a hollow hemispherical portion 1b from above and below, respectively, and then a snap fit or a screw and a nut. Are joined together and assembled to the hollow hemispherical portion 1b. Reference numeral 4 denotes a leaf spring which is fixed to the upper ring 2a ₁ by means of a screw and a nut 5 at four locations along the circumference of the belt-shaped ring 2a. Pieces 6 and 6 are attached, and both ends thereof are brought into pressure contact with the outer surface of the hollow hemispherical portion 1b via the felt pieces 6 and 6 by spring pressure. The leaf spring 4 to which the felt pieces 6, 6 are attached constitutes a support for the air blowing member 1. Reference numeral 7 is an airtight felt ring attached to the inner surfaces of the upper ring 2a ₁ and the lower ring 2a ₂ , respectively, and is in contact with the outer surface of the hollow hemispherical portion 1b. The air outlet is attached to the ceiling 8 at the attaching portion 2b as shown in FIG. 1, and the air outlet member 1 is connected to the duct 10 via the attachment tube 9. In FIG. 1, reference numeral 11 denotes a circular damper that is curved and formed on a spherical surface disposed at a connecting portion between the air blowing portion 1a and the hollow hemispherical portion 1b. The damper 11 is rotated by rotation of the knob 12. The air blowout portion 1a is opened and closed, and 13 is a leaf spring for pressing the damper 11 against the base portion of the air blowout portion 1a to open and close the air blowout portion 1a reliably.

A flocked layer may be provided on the outer surface of the air blow-out member 1, and the air blow-out port is attached to the ceiling 8, but should be directly attached to the duct 10 by an attachment portion having the same shape as the attachment portion. Alternatively, it may be attached to a duct that opens to the wall. The number of leaf springs 4 may be one to three. When the flocked layer is provided, and the slip between the felt piece 6 and the felt ring 7 is poor, a slippery sheet piece may be attached to the inside of the felt piece 6 and the felt ring 7. .

Explaining the operation of the above air outlet, both ends of the leaf spring 4 attached to the attachment portion 2b are pressed against the outer surface of the hollow hemispherical portion 1b of the air outlet member 1 via the felt pieces 6, 6. Therefore, the air blowing member 1 can be moved with a light force and does not move with a slight force after setting the desired tilt position. The force for rotating and tilting the air blowing member 1 is adjusted by bending the leaf springs 4 to adjust the spring pressure, and / or by adjusting the number of leaf springs 4 to, for example, 3 to 1.

[0013]

[Effect of device]

 According to the present invention, since the position of the air blowing member is held by the spring pressure, it is not necessary to generate an excessive contact pressure in the airtight felt ring, and the felt ring is crushed or solidified by the pressure to be airtight. There is no inconvenience to damage. The air blow-out portion of the air blow-out member can be easily rotated and tilted to a desired angle, and after being set, it can be fixed so as not to move from that position with a slight force, and this effect is obtained. Therefore, there is an effect that the force for rotating and tilting the air blowing member can be easily adjusted to an appropriate value.
