Description

  BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a variable angle type finned air-conditioning air outlet and a frame material for forming the frame.

  In the air outlet apparatus used for the air conditioner, the angle of rotation around the axis is changed between the inner surfaces of the frame facing each other at both ends of the shaft integral with the wind direction adjustment fin on the inner surface of the frame whose front shape is rectangular. There is one that is attached as possible (see, for example, Patent Document 1).

  In such a blowout apparatus, when the end face of the fin is in contact with the inner surface of the frame and the shaft is attached to the frame, when changing the angle of the fin around the axis, the end face of the fin is the frame There is a risk that the coating on that portion may peel off or the angle adjustment of the fin may become uneven due to the friction at that time.

  In order to eliminate such a possibility, the shaft hole for inserting the shaft of the fin in the frame is subjected to burring to form a projecting cylindrical portion of a short dimension around the axial hole, and the projecting cylindrical portion is used as a spacer. There is one in which the end surface is not in direct contact with the inner surface of the frame (see, for example, Patent Document 2).

FIG. 3 is an enlarged cross-sectional plan view taken along line III-III of FIG. It is an expansion vertical rear view in the IV-IV line of FIG. It is a perspective view of a frame-forming mold material.

Hereinafter, an embodiment of the present invention will be described based on the drawings.
As shown in FIGS. 1 to 4, the variable-fin type air-conditioning air-outlet device with variable-angle fin is provided with a horizontally long rectangular rectangular tubular frame 1 that opens toward the front.

The frame 1 comprises a pair of left and right side pieces 2 and 2, an upper piece 3 and a lower piece 4.
The side pieces 2 and 2, the upper piece 3 and the lower piece 4 are rectangular frame shapes by cutting a mold material 5 as shown in FIG. 5 into an appropriate length and abutting and joining their end faces to each other. Is formed.

  The mold material 5 is formed by extruding a synthetic resin material having heat insulating properties, and has two flat plate-like base pieces 5a and two parallel parallel protruding pieces formed on one side face of the base piece 5a. An outwardly directed flange 5d extending perpendicularly to the base piece 5a in a direction opposite to the surface on which the ridges 5b, 5c are provided, from the side edges of the strips 5b, 5c and the base piece 5a The free end of the outward flange 5d is made up of a short folded edge 5e continuously provided so as to be folded back at a right angle to the base piece 5a side.

  Specific examples of the molding material 5 include, for example, urethane resin, vinyl chloride, vinylidene chloride resin, polyamide resin, polyimide resin, polyester resin, polyolefin resin, polystyrene resin, phenol resin, epoxy resin, melamine resin, vinyl acetate resin, Or it can be a fluoroplastic.

  As shown by a two-dot chain line in FIG. 5, the mold material 5 is expanded by 45 ° in the longitudinal direction of the mold material 5, with the surface of the base piece 5 a on which the ridges 5 b and 5 c are provided The two pieces 2 and 2 and the upper piece are made so that both end faces have an inclination angle of 45 ° with respect to the longitudinal direction by cutting to an appropriate length with two cut faces A and B inclined so as to open. 3 and the lower piece 4, and the end faces of the outer flange 5d are butted and fixed to each other as shown in FIGS. 1 and 4 and the outward flange 5d between the base piece 5a and the turning edge 5e. The frame 1 is formed by securing each side of the rear end L-shaped joining fitting 6 on the rear surface.

  As a result, on the inner surfaces of the side pieces 2 and 2 and the upper and lower pieces 3 and 4 in the frame 1, two front and rear ridges 5b and 5c directed in the longitudinal direction are formed, and the end faces are 45 ° to each other. The front plate 7 of the blowout device is formed by the outward facing flange 5d which is butted and joined at an inclination angle.

At the center of the front ridges 5b, 5b of the upper piece 3 and the lower piece 4, a plurality of shaft holes 8 directed vertically are aligned vertically at equal intervals and are drilled at equal intervals There is.
At the center of the rear ridges 5c, 5c in the two side pieces 2, 2, a plurality of shaft holes 9 facing in the left-right direction are drilled so as to be equal to each other and arranged vertically at equal intervals. .

At the front in the frame 1, a plurality of wind direction adjusting vertical fins 10 directed in the vertical direction can be changed in angle in the horizontal direction so that each can be angled about the axis L1 (see FIG. 2) directed in the vertical direction. They are arranged at equal intervals.
At the rear in the frame 1, a plurality of wind direction adjusting horizontal fins 11 facing in the left and right direction can be changed in angle around the axis L2 (see FIG. 3) respectively facing in the left and right direction. It is arranged side by side at intervals.

The cross-sectional shape of the vertical fins 10 and the horizontal fins 11 is a rhombus, and a rhombus insertion hole 12 having a similar shape to the outer shape is provided at the center thereof.
Each vertical fin 10 is in contact with each axial hole 8 from the outside of the frame 1 so that both end surfaces respectively abut on the top surfaces of the front ridges 5b and 5b of the upper piece 3 and the lower piece 4 facing each other. The fixing screw 13 as a tapping screw that has been inserted is screwed into the insertion hole 12 as a lower hole, and is attached to the frame 1 so as to be changeable in angle.
Similarly, each horizontal fin 11 also has each axial hole 9 from the outside of the frame 1 in such a manner that both end surfaces respectively abut on the top surfaces of the rear ridges 5c, 5c in the opposite side pieces 2, 2 facing each other. The fixing screw 13 inserted in the screw is screwed into the insertion hole 12 as a lower hole so that the angle can be changed to the frame 1 and attached.
Therefore, in this example, each fixing screw 13 is an axis for adjusting the vertical fins 10 and the horizontal fins 11 at an angle.

  In order to change the mounting angle of the vertical fins 10 and the horizontal fins 11, loosen the fixing screws 13 screwed to their both ends and rotate them in the desired direction around the axis L1 or the axis L2. After that, the fixing screw 13 may be tightened again.

The amount of protrusion of each of the ridges 5b and 5c in the mold material 5 from the base piece 5a is that when the vertical fin 10 or the horizontal fin 11 is angularly adjusted about the axis L1 or L2, the end faces of these fins 10 and 11 are base pieces It may be an extent not in contact with 5a, for example, about 0, 1 to 1 mm.
The width of each of the protrusions 5b and 5c may be larger than the diameter of the axial holes 8 and 9 formed therein, and for example, the diameter L + 2 to 6 mm of the axial holes 8 and 9 is preferable.

  By providing such ridges 5b, 5c on the inner surface of the frame 1, only the peripheral portion of the fixing screw 13 at the end face of the fins 10, 11 abuts on the top surfaces of the ridges 5b, 5c. Since portions other than the peripheral portion of the tapping screw 13 at the end face of the frame 11 are separated from the inner surface of the frame 1, the end faces of the fins 10 and 11 rub against the inner surface of the frame 1 and the coating of that portion is peeled off The friction at that time can prevent the angle adjustment of the fins 10 and 11 from becoming uneven.

Further, since it is only necessary to form the projections 5b and 5c in advance in the mold member 5 forming the frame 1, as in the prior art, the shaft holes 8 and 9 in the frame 1 are subjected to complicated processing such as burring. It does not need to be processed and can be easily manufactured.
Furthermore, each of the ridges 5b, 5c also acts as a reinforcing rib and can contribute to the improvement of the strength of the frame 1, and it becomes positioning when the shaft holes 8, 9 are provided. The drilling operation of 9 is facilitated.

  The front edge of the frame is provided with an outward flange 5d facing in a direction perpendicular to the surface forming the inner surface of the frame, and the ends of the outward flange 5d are joined to form the front plate 7, so a separate front plate The number of parts can be reduced.

In addition, since the frame 1 is formed of a synthetic resin material having heat insulating properties, it is possible not only to process easily but also to prevent condensation from occurring on the surface of the frame 1 at the time of cooling.
In particular, condensation is apt to occur on the surface of the outward flange 5d to be the front plate 7, but this can be effectively prevented.

  An L-shaped mounting bracket 14 in a side view is fixed by rivets 15 to the rear end both sides of the base piece 5 a in the upper piece 3 and the lower piece 4, and inward of the frame 1 in each mounting bracket 14. The frame 1 is attached to the open end of the air conditioning duct (not shown) with the fixing screw (not shown) inserted in the mounting hole 16 formed in the laterally extending long hole provided in the protruding attachment piece 14a. It can be done.

  By attaching the frame 1 to the open end of the air conditioning duct, the air outlet port is completed, and the air conditioning air that has circulated in the duct passes through the frame 1 and the horizontal fins 11 and While being rectified by the vertical fins 10, they are deflected by the attachment angles of the fins 11 and 10, and are fed from the frame 1 in a desired direction.

  According to the variable angle type air conditioner vent with air conditioner of the present invention configured as described above and the frame forming mold 5 thereof, the shaft holes 8 and 9 are subjected to complicated processing such as burring. Instead, most of the end faces of the fins 10 and 11 can be separated from the inner surface of the frame 1, whereby the end faces of the fins 10 and 11 rub against the inner surface of the frame 1 and the coating on that portion is peeled off The friction at that time can prevent uneven adjustment of the angles of the fins 10 and 11 and can also prevent condensation during cooling.

The present invention is not limited to the above embodiment, and can be implemented, for example, in the following modified form.
(1) The frontal shape of the cylindrical frame 1 is a circle, a polygon other than a tetragon, or the like.
(2) Either one of the vertical fins 10 and the horizontal fins 11 is omitted, and in accordance therewith, only one ridge 5b or 5c provided on the mold 1 is provided.
