DESCRIPTION STRUCTURE TO ATTACH REGULATORS AND METHOD TO ATTACH REGULATORS 5 Technical Field The present invention relates to a structure for attaching regulators and method for attaching regulators to an adjunct regulator within various types of boxes / structures in an air conditioner for a vehicle system or the like. k10 This application is based on a Japanese Patent Application No. Hei 11- I03344, of which its components are incorporated herein by reference.

Background Art 15 In an air conditioner for a car, it has been a conventional practice to attach regulators to make temperature adjustments or selective exchange of external ports within a box / structure. Figs. 5 and 6 show a view of an air conditioning unit used in a conventional air conditioning system for a vehicle. The ports of departure 2a, 2b and 2c open in a box / structure 1. The regulators 3a, 3b and 3c are attached to the output ports 2a, 2b and 2c respectively. In order to facilitate the coupling of each regulator 3a, 3b and 3c within the box / structure 1 in this case, the box / structure 1 is designed to be formed by a combination of two separate parts left and right (1 L lzq ., 1R / Der.). As a result of this design, facilitates easy assembly by passing rotating shafts provided at each end of the ? * , • 2 regulators in bearings in the box / structure 1, and when inserting these rotary shafts in these bearings. In addition, another conventional example shown in Fig. 7 employs a design in the • which box / structure 1 is divided into upper and lower part (1a, 1b) in one position in which a bearing 5 for supporting a rotary shaft 4 of a regulator 2 can be divided into upper and lower portions. This design also facilitates the assembly by inserting the rotary shaft 4 from a vertical direction to the bearing 5. The regulator 2 described above can be opened and closed by means of a lever 6 attached to the outer part of the box / structure 1. As shown in FIG. Fig. 8, this, lever 6 is attached by means of a fixing at the end of the rotating shaft 4, which is • projected to the exterior of the box / structure 1. Alternatively, as shown in Fig. 9, when the rotating shaft 4 is provided with a certain degree of thickness, then an axis 6a projecting outwards is provided from lever 6, and can be attached to the hook in a hole of axis 4a, which is provided on the rotary shaft 4. In this type of structure for attaching the lever, it is not necessary to provide the rotating shaft 4 projecting out of the regulator 2. As a result, the regulator 2 can be shortened for a quantity MR corresponding to the rotary axes 4 at either end thereof. Therefore, the regulator 2 can be incorporated into the structure box 1 when using a suitable opening such as an exit port or a port communicating to another box / structure. However, in the conventional design described above, it is typically necessary to decide where the box / structure will be divided after taking into account the incorporation of the regulator within the box / structure. Therefore, there are limitations in the inclination and direction of the plurality of installed output ports, which results • in less design freedom.

When using the structure to attach the lever, shown in Fig. 9, when the rotary shaft of the regulator has a certain thickness, the regulator can be assembled from an opening as an exit port without considering the division of the box / structure. • However, in the case where the rotating shaft is not thick enough 5 and it is not possible to employ a design in which the box / structure is divided into the bearing, or a design in which the box / structure is divided in left and right portion and the rotary axis is inserted in the middle of the portions, then it is not possible to incorporate the regulator inside the box / structure. Specifically, when there are a large number of regulators to be incorporated, then it is very difficult to employ a design to divide the box / structure that is suitable for all the regulators. The present invention was conceived considering the problems described above and aims to provide a structure for attaching regulators and a method for attaching regulators in which a regulator with a narrow rotary shaft can be assembled within a box / structure by using openings formed in Several types of 15 boxes / structures such as a box or duct.

BEST MODE FOR CARRYING OUT THE INVENTION A characterization of the structure for attaching regulators and method for attaching regulators according to the present invention based on the figures will now be explained.

As shown in Fig. 1, the structure for attaching regulators comprises a box structure 10, members of the walls 11 and 12 of the box / structure 10 positioned opposite one another, an opening 13 provided in the upper portion of the box / structure 10, a regulator 20 and a lever 30 for turning (opening / closing) the regulator 20. Fig. 1A shows a completed assembly in which both ends of the regulator 20, which is provided between the members of the opposite walls of the box / structure 10, are supported by the members of the walls 11 and 12 to allow free rotation of the regulator. In other words, Fig. 1A shows the state in which the regulator 20 is in the position of the center of the rotation. An orifice of the shaft 14 is provided in the wall member 11 to allow passage through the wall member 11 and reach the outer part of the wall member 11. A fixing member of the shaft 31 of the lever 30 explained below is inserted rotatably into the bore of the shaft 14. This bore of the shaft 14 has a larger cross section than that of a thin shaft member of the regulator 22 of the regulator 20 explained below, a support hole 15 is provided in the other wall member 12 and functions as a bearing for a regulator shaft member 21 projecting outwardly from the regulator 20. Note that this support hole 15 may come with an intermediate thickness as shown in the figure, or it may be a hole passing through the wall member 12, according to various conditions such as the thickness of the wall member 12. A concave groove 16 is provided on the inner surface 11a of the wall member 11 to which the lever 30 is attached. This concave groove 16 is rectangular in shape and is open at the upper end towards the opening 13. The width W of the concave groove 16 is smaller than the length I, in the vertical direction. A center line extending along the longitudinal direction of the concave groove 16 - M * t 'is in the vertical direction, and the concave groove 16 has a positional relationship with the regulator 20, said that deviates by approximately 90 ° from the longitudinal plane of the regulator 20 when the regulator 20 is horizontal and in position central rotation.

• The regulator 20 is a plate-shaped member provided with the shaft member 5 of the regulator 21 and the thin shaft member of the regulator 22 projecting outward from either end of the regulator 20. a rectangular positioning plate 23 which functions as A positioning member is provided on the base of the thin shaft member of the regulator 22 on the side of the regulator thereof, on the wall member 11 to which the lever 30 is attached. This positioning plate 23 is designed to enter the concave groove described above 16. The length and width of the positioning plate 23 is smaller than those of the concave groove 16. It is preferable that the thickness of the positioning plate 23 is smaller than the thickness of the positioning plate 23. depth of the concave groove 16. In the characterization shown in the figures, the thin shaft member of the regulator 22 is square in cross section. Since the objective is that the thin shaft member of the regulator 22 and the lever 20 explained below are connected in a manner that allows the transmission of torsion, not only square shapes may be used, but also polygonal shapes, such as a triangle or hexagon; which can be easily • manufactured. In other words, any of these shapes is acceptable for the transverse form of the thin shaft member of the regulator 22, as long as it fits into the shaft bore on the side of the lever 30 and allows torsion transmission. The shaft fixing member 31 projects out of a main body of the lever 32 so that the lever 30 has the L-shape. The lever 30 is typically connected to a driving member via a connecting structure or the like not illustrated. in the figures. As shown in Fig. 1C, this shaft fixing member 31 has a hollow cylindrical shape. A latching hole 33 is formed in the center of the i '»... -! r ~ - A.Jjj & - .. ^ rf-. . i. . - "- ,. < -, fixing member of the shaft 31 into which the thin shaft member of the regulator 22 is inserted, joining in such a way as to allow the transmission of torsion. The outer peripheral surface of the fixing member of the shaft 31 is circular in cross section and inserted into the hole of the shaft 14 of the wall member 11 in such a manner as to allow rotation. In other words, the latching hole 33 in this representation has a square cross-sectional shape, equivalent to that of the thin shaft member of the regulator 22 so that the thin shaft member of the regulator 22 can be engaged in the latching hole. without backlash. Furthermore, the circular cross-sectional shape of the fixing member of the shaft 31 has the same diameter as the hole of the shaft ^ fc 10 14, so that the fixing member of the shaft 31 is inserted in the hole of the shaft 14 to allow a smooth rotation without noise. The lever 30 is designed to connect the thin shaft member of the regulator 22 which has been inserted into the hole of the shaft 14 by pushing the lever 30 on the outside of the wall member 11 in the direction of the axis. As a result, this offers excellent operation and allows the lever 30 to be fixed securely in place. Now we will explain the operation of a structure to attach regulators of the above described design based on the method to attach the regulator (sequence). Fig. 2 shows the state before assembling the regulator 20. in the first step, the regulator 20 is inclined towards the concave groove 16 that is formed towards the inner surface 11a of the wall member 11 and is continuous from the opening of the opening. the box / structure 13. Mainly, the end of the thin shaft member of the regulator 22 and positioning plate 23, which is provided at the base of the thin shaft member of the regulator 22, are inclined downwards, inserted in a concave groove 16 and 25 descend by sliding along the concave groove 16. as "¿^. ,, ^ a« ^ ... ^ ^ UUUU * - - - - »« .- * > . * - result, the thin shaft member of the regulator 22 is inserted in the hole of the shaft 14 which opens in the concave groove 16 (see Fig. 3). The concave groove 16 functions as a recess for the shaft member of the • regulator 21 and the thin shaft member of the regulator 22. The hole of the shaft 14 is more 5 large in cross section than that of the thin shaft member of the regulator 22, so that the thin shaft member of the inclined regulator 22 is easy to insert. The presence of the concave groove 16 is a reason why the thin shaft member of the regulator 22 is inserted immediately into the hole of the shaft 14. The second step after the thin shaft member of the regulator 22 is inserted into the hole of shaft 14 is as follows. The positioning plate 23 is inserted ^ into the concave groove 16 and the shaft member of the regulator 20 is no longer tilted but leveled. The positioning plate 23 is in strong contact with the opposite surface in the concave groove 16 when moving the regulator 20 towards the side of the wall member 11 where the lever is attached. The lengths of the shaft member of the regulator 21 and the thin shaft member of the regulator 22, and the depth of the concave groove 16, are accommodated such that the end surface of the shaft member of the regulator 21 can be inserted into the the wall member 12 from its inner surface 12a. By horizontally moving the regulator 20 towards the member of the inner wall 12, the member of the axis of the regulator 21, which is circular in cross section, can be inserted into the support hole 15, which has the same circular cross section and is provided in the wall member 12. This arrangement is shown in Fig. 4. The thin shaft member of the regulator 22 is loose inside the hole of the shaft 14, which has a larger transverse shape than that of the thin shaft member of the regulator 22. In addition, a part or all of the positioning plate 23 is within the concave groove 16 and is Aa ^ jj ^^ extends in the central direction of the box / structure to this point in time. The regulator 20 is in the coupling position in this state. Subsequently, in the third step with the positioning plate 23 being out of the concave groove 16, the regulator 20 is rotated approximately 90 ° from the coupling position towards the rotation position. In the characterization shown in the figure, the regulator 20 moves 90 ° from the coupling position in which the regulator is vertical (see Fig. 4), to the rotational position in which the regulator is horizontal as shown in FIG. a Fig. 1A. The regulator 20 in the rotational position can oscillate using the horizontal as the center of rotation. The length of the positioning plate 23 is longer than the width W of the concave groove 16 in this rotating center, then the positioning plate 23 intersects the concave groove 16 (see Fig. 1B), and can not be inserted into the concave slit 16. As a result, the positioning plate 23 and the inner surface 11a of the wall member 11 come into contact, then positioning occurs along the axis direction of the regulator 20. Therefore, if the plate The rectangular positioner 23 does not have a certain length dimension, so the limits of which the regulator 20 can oscillate are reduced. Since the angle formed between the center line of the positioning plate 23 and the center line along the longitudinal direction of the concave groove 16 is set to be around 90 °, it is possible to increase the limits within which the regulator 20 can oscillate. Then, the shaft fixing member 31 having the same circular shape as the hole of the circular shaft 14 is inserted, and the thin shaft member of the regulator 22 which is square in cross section is engaged with the engagement hole 33 in the fixing member of shaft 31, engagement hole 33 having the same shape - transverse that the thin shaft member of the regulator 22. The thin shaft member of the regulator 22 and the lever 30 are connected in such a way as to allow the transmission of torsion, so that the shaft member of the regulator 21 and the limb Fixation of the shaft 31 can be rotated smoothly using the support hole 15 and the hole of the shaft 14 as their respective bearings. 5 The operation for attaching the lever 30 can also be performed before moving the regulator 20 to the rotational position. Mainly, in this case, the regulator 20 can be moved to the rotational position after attaching the lever 30. As described above, the structure for attaching regulators and the method for attaching regulators of the present invention allow the regulator 20 k 10 which is longer than the members of the walls 11 and 12 that are to be assembled within the box / structure upon insertion through the opening 13. As a result, it is not absolutely necessary to separate the box structure to the coupling position. for the regulator 20. Furthermore, when a plurality of regulators 20 are attached, it may be the case that the directions for inserting and attaching the regulators are not same. However, even in this type of situation, the present invention allows the regulators to be assembled without considering the division of the box / structure. As long as there is an opening, such as a connection opening of a box / structure or a properly shaped outlet port, then the present invention can be executed by employing these openings effectively. Furthermore, in the preceeding characterizations, the length of the positioning plate 23 is arranged to be level with the regulator 20. However, this can be altered properly after taking into account the position of the opening 13 and the limits of oscillation for the regulator 20. Mainly, the length of the positioning plate 23 can be set so that the angle between the long side of the positioning plate 23 and the regulator 20 is 90 ° or 60 °, for example.

Industrial Application The structure for attaching regulators and the method for attaching regulators of the present invention provide the following effects. # (1) Since an opening in the box or the like can be used to assemble the regulator shaft member 5, the box / structure does not need to be divided. Therefore, there is an improvement in the degree of design freedom allowed. (2) There is a greater freedom with respect to the placement of the regulator, since it can be attached in a position where the assembly of the regulator can not be done in a conventional design and method. 10 (3) There is a great improvement in the operability of the assembly operation for the • shaft fixing member on the lever that fixes the thin shaft member of the regulator in such a way as to allow torsion transmission. Therefore, it is possible to prevent damage to the box or the like due to improper assembly. ??? ¡& \ - ~ J * A? »**. l? dL - *, i -. ^ ".- ** &"; , - * -. «- ^ A * ...,. - ^ - "1. **, -. -, -.." - '.ifFr. * - ft f - t- »ÍlW¡M- > ..
