Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a structure for mounting a blow-out grill to an air-conditioning case body installed in an air-blowing part of an air-conditioner mounted on a vehicle, and in particular, a plurality of blow-out grills are rotated on one air-conditioning case body on the same axis. The present invention relates to a structure for mounting an outlet grill, which is freely supported in parallel and regulates the vertical rotation angle of each outlet grill, and is also capable of further rotation.

[0002]

[Prior art]

 When multiple air outlet grills are installed side by side on a single air conditioning case as described above, the conventional attachment structure for each air outlet grill to the air conditioning case has a spacer on the shaft of each air outlet grill, and the upper and lower sides of the air outlet grill. The rotation angle is regulated by forming an engaging surface or the like on a part of the inner wall of the rear part of the air conditioning case, which is the sliding contact surface of the outlet grill.

That is, as the braking force at the time of rotating the blowing grille, the frictional force generated between the side wall surface of the grille and the side wall surface of the spacer or the three-tone case body is used, and the vertical turning angle of each blowing grille is adjusted. The limit was specified by the above-mentioned attachment surface.

[0004]

[Problems to be solved by the device]

 However, according to such a mounting structure, in order to secure an appropriate braking force when the outlet grill is rotated, not only the spacer is required to be processed with high precision, but also the spacer is attached to the air-conditioning case body. At that time, a high degree of skill was required, leading to cost up.

Further, the vertical rotation angle of the blowout grill is restricted by the above-mentioned engaging surface and the like, and further rotation is not allowed. For example, the blowout grill is rotated beyond the above rotation angle to blow air. It was impossible to try to completely block the air blown into the passenger compartment by blocking the outlet.

The present invention has been made for the purpose of eliminating the above-mentioned problems, does not require the processing accuracy of the spacer, and is easy to attach the spacer to the air-conditioning case body. An object of the present invention is to provide a structure for mounting a blow-out grill that allows the grill to be rotated further beyond the same angle even though the vertical rotation angle of the grill is regulated with certainty.

[0007]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention is provided with two or more louvers on the front of which a plurality of wind direction adjusting plates that rotate in unison are mounted inside an air conditioning case body installed at an air conditioning outlet of a vehicle. The air-conditioning case body has an attachment portion for attaching and fixing a shaft portion support body of a butt end shaft portion of the air outlet grill, the attachment structure for attaching the blowout grills in series. The part support is composed of a rectangular plate-shaped spacer part and a pair of upper and lower locking claws which are formed at the tips of the legs extending in parallel from one end of the spacer part and which are engaged with the engaging part of the air conditioning case body. The ring-shaped bearing portions project from the left and right side surfaces of the spacer portion on the same axis, and the projections each having an arc-shaped cross section are formed on the outer peripheral surface of each of the ring-shaped bearing portions. , The butt of the blow-out grill That pin-like projection that abuts the projection of the support comprises protrudes have a major configuration.

[0008]

[Action]

 When installing the blowout grill to the air conditioning case body, first fix the air conditioning case body to the ceiling panel, etc. with screws, and then attach the horizontal shafts at the right and left ends of the two blowout grills that are connected in series to each other. And the horizontal shafts at the abutting ends of the left and right outlet grills are respectively fitted to the left and right ring-shaped bearings of the shaft support.

In this state, after each locking claw of the shaft support is fixedly attached to the engagement portion of the air conditioning case body, the finisher is fitted into the front surface of the air conditioning case body to complete the assembly. To assemble the shaft support to the air-conditioning case, simply push the spacer part of the shaft support into the engaging part, fit the leg into the case, and attach the locking claw at the tip of the leg to the leg. By elastically deforming the part, simply inserting it into the pawl engaging hole restores the legs elastically when the pawl passes through the pawl engaging hole, and at the same time the pawl is clawed. It is attached to the attachment hole and the installation is completed.

The blowout grill assembled in this way in the air conditioning case body rotates upward about the horizontal shaft portion, but when rotated by a predetermined angle, the pin-shaped projection protruding from the abutting side surface of the blowout grille is the shaft portion. The ring-shaped bearing portion formed on the spacer portion of the support member abuts against the protrusion on the outer peripheral surface, and further rotation is restricted. However, at this time, when the rotation power is further increased to rotate the blowout grill, the pin-shaped projections pass over the projections on the outer peripheral surface of the ring-shaped bearing portion and can be rotated by the rotation angle or more. Therefore, when trying to stop the blowing of air from a part of the outlet grills, if the outlet grills are rotated beyond the predetermined rotation angle as described above, a part of the plurality of outlet grills can be rotated. The blow-out grill part of is completely blocked, and no air is blown out at that part.

Further, a large number of wind direction adjusting plates 2 are connected by a single connecting rod 3 via a pin 2b, and when one wind direction adjusting plate 2 rotates about a rotating shaft portion 2a, the connecting rod 3 is moved. Through this, all the wind direction adjusting plates 2 are simultaneously rotated in the same direction. Therefore, an operation knob 4 for rotating operation is integrally attached to one of the wind direction adjusting plates 2. Further, in the center of the outer surface of the left and right side walls of the grill main body 1a, a pair of left and right horizontal shaft portions are provided in the air conditioning case body 5 for supporting the blowout grill 1 rotatably around the horizontal axis. 1c and 1d are projected. The above-mentioned blow grill structure is essentially the same as the conventionally known structure.

According to the present invention, two blowout grills 1 having such a basic structure are supported by connecting them to the air conditioning case body 5 with the horizontal shaft portions 1c and 1d on the same line. Therefore, in the present invention, the shaft support 6 which is a part of the feature of the present invention is attached to the abutting portion of the two outlet grills 1, that is, the central portion of the air conditioning case body 5. Further, in the present invention, pin-shaped projections 1e are projected on the abutment side surface of the blowout grill 1 in parallel with the horizontal shaft portion 1d at a predetermined interval in the radial direction. The outer ends of the two consecutively provided blowout grills 1 have their respective horizontal shaft portions 1c fitted and supported in shaft support holes 5a formed in the left and right side walls of the air conditioning case body 5, as in the conventional case. ..

As shown in FIG. 1, the coaxial portion support 6 includes a spacer portion 6a having a rectangular plate shape, a flange portion 6b formed at one end of the spacer portion 6a, and a leg portion 6c extending in parallel from the flange portion 6b. It is composed of a pair of upper and lower engaging claws 6d formed at the tip of each of them, and left and right ring-shaped bearing portions 6e having the same center are respectively projected from the left and right side surfaces of the spacer portion 6a. Further, on the outer peripheral surface of each of the left and right ring-shaped bearing portions 6e, protrusions 6f each having an arc-shaped cross section are formed.

On the other hand, in order to attach the shaft support 6, the central portion of the air conditioning case body 5 is integrally provided with an engaging portion 7 for engaging the above-mentioned pair of upper and lower engaging claws 6d. . As shown in FIGS. 3 and 4, the engagement portion 7 includes a case portion 7a into which the leg portion 6c of the shaft portion support body 6 is fitted from the front surface of the air-conditioning case body 5, and a rear wall surface of the case portion 7a. It is composed of a pair of upper and lower claw engaging holes 7b which are formed at the same time and through which the respective locking claws 6d at the tip of the leg 6c are inserted and at the same time are engaged by utilizing the elasticity of the leg 6c.

When the shaft supporting body 6 is attached to the engaging portion 7 of the air conditioning case body 5, the pair of left and right ring-shaped bearing portions 6d of the coaxial portion supporting body 6 have the two outlet grilles as described above. The horizontal shaft portions 1d protruding from the abutting side faces of 1 are fitted and supported. At this time, the pin-shaped protrusion 1e protruding from the abutting side surface of the blowout grill 1 is located close to the outer peripheral surfaces of the pair of ring-shaped bearing portions 6e. Further, as shown in FIG. 5, an arc-shaped guide wall 5b is formed in a part of the rear part of the air conditioning case body 5 along the rear end shape of the wind direction adjusting plate 2, and the guide surface of the guide wall 5b is formed. A protrusion 5c is formed at a predetermined portion, and the downward rotation angle of the blowout grill 1 is restricted by the protrusion 5c.

Further, according to the present invention, in the pair of left and right outlet grills 1, as shown in FIG. 3, at the mounting ends for the air-conditioning case body 5, a suspicious adjustment plate 8 having substantially the same shape as the wind direction adjustment plate 2 is provided. The fixing plate 8 for fixing the same is connected to the grill body 1a by a supporting plate 8a. The suspicious adjustment plate 8 and the support plate 8a are formed with screw mounting holes 5e in the rear walls 5d at the left and right ends of the air conditioning case body 5 in order to attach the air conditioning case body 5 to, for example, a ceiling panel (not shown). The support plate 8a shields the screw mounting hole 5e from the front surface, and at the same time, the hollow portion formed in the front portion of the rear wall 5d is suspected by the suspected adjustment plate 8 and blown out. The front of the grill 1 looks good.

In order to attach the air outlet grill 1 having the above structure to the air conditioning case body 5, the air conditioning case body 5 is first fixed to the ceiling panel or the like with screws, and then the right ends of the two air outlet grills 1 and 1 are connected. The horizontal shaft portions 1c, 1c at the left end are fitted into the shaft supporting holes 5a, 5a formed at the side ends of the air conditioning case body 5, respectively, and the horizontal shaft portions 1d at the abutting ends of the left and right outlet grills 1, 1 are 1d are respectively fitted to the left and right ring-shaped bearing portions 6e, 6e of the shaft support 6.

In this state, after fixing the respective locking claws 6d, 6d of the shaft support 6 to the engaging portion 7 of the air conditioning case body 5, the finisher 9 is fitted on the front surface of the air conditioning case body 5. The assembly is completed. To assemble the shaft support 6 to the air-conditioning case 5, simply push the spacer 6a of the shaft support 6 into the engagement part 7 to fit the leg 6c into the case 7a, and the end of the leg. When the locking claw 6d passes through the claw engaging hole 7b by simply inserting the locking claw 6d into the claw engaging hole 7b by utilizing the elastic deformation of the leg 6c, the leg 6c becomes the original shape. At the same time, the locking claw 6d is engaged with the claw engaging hole 7b, and the mounting is completed.

The blow-out grill 1 assembled in the air-conditioning case body 5 as described above rotates upward about the horizontal shaft portions 1c and 1d as shown in FIG. The pin-shaped protrusion 1e protruding from the abutting side face abuts against the protrusion 6f on the outer peripheral surface of the ring-shaped bearing portion 6e formed on the spacer portion 6a of the shaft support 6, and the further rotation is restricted. However, at this time, when the rotating power is further increased and the blowout grill 1 is rotated, the pin-shaped projection 1e rides over the projection 6f on the outer peripheral surface of the ring-shaped bearing portion 6e and can be rotated by the rotation angle or more. To Therefore, when trying to stop the blowout of the air from a part of the blowout grill 1, if the blowout grill 1 is rotated beyond the predetermined rotation angle as described above, as shown in FIG. The part of the blow-out grill 1 is completely closed and air is not blown out.

Further, by configuring the rotating mechanism of the blowout grill 1 with respect to the air conditioning case body 5 as described above, the air conditioning case body is assembled with the blowout grill 1 and the finisher 9 by using screws. It is also possible to attach and fix 5 to a ceiling panel or the like. In this case, driver insertion holes as shown by phantom lines in FIGS. 2 and 3 are formed in the upper and lower frame portions 1f and 1g of the outlet grill 1 at the portions corresponding to the screw mounting holes 5e formed in the air conditioning case body 5. It is preferable to form 10. By forming the driver insertion hole 10, the blowout grill 1 is installed inside the air conditioning case body 5 before the driver insertion hole 10 and the screw mounting hole 5e are opposed to each other before mounting on a ceiling panel or the like. It is rotated beyond the movement angle, the screw mounting hole 5b of the air conditioning case body 5 is brought into contact with a mounting portion such as a ceiling panel, and a driver is inserted into the driver insertion hole 10 of the blowing grill 1 to blow the grill. Tighten the screw from the outside of 1 to fix it.

According to the above-described embodiment, the downward rotation of the outlet grill 1 is restricted by the protrusion 5c formed on the guide wall 5b of the air conditioning case body 5 shown in FIG. Although the above rotation is disabled, a pin-shaped protrusion having a structure similar to that of the pin-shaped protrusion 1e instead of the protrusion 5c is provided at a symmetrical position with the center of rotation of the abutment side surface of the outlet grill 1 sandwiched. In addition to the projection 6e, projections each having an arc-shaped cross section are newly projected on the outer peripheral surface of the left and right ring-shaped bearing portions 6d at symmetrical positions with respect to the center of rotation.

With this configuration, the outlet grill 1 can be rotated in the vertical direction at a predetermined rotation angle, and further, when a turning force is further applied, one of the pair of pin-shaped projections is It becomes possible to go over one of the projections on the other side and turn more than the specified turning angle.

[0024]

[Effect of device]

 As is apparent from the above description, according to the attachment structure of the outlet grill of the present invention, the shaft support for supporting the abutting end shafts of two or more outlet grills can be easily attached to the air conditioning case body. In addition, between the coaxial support and the blowing grill, a projection with a semicircular cross section formed on the ring-shaped bearing of the shaft support and a pin-shaped projection protruding from the abutting end face of the grille collide. By contacting the grille, the vertical rotation angle of the grille is regulated to a predetermined angle, and if further rotation power is applied, the pin-shaped protrusions will pass over the protrusions having the semicircular cross section and easily exceed the rotation angle. Since the rotation is allowed, for example, when extra air is not blown out, a part of the grill can be largely rotated to close a part of the air outlet.
