Description

DETAILED DESCRIPTION OF THE INVENTION << Industrial Application Field >> The present invention relates to a mounting structure of a finisher to be mounted on the front surface of an air conditioning case body for a vehicle.

<< Prior Art >> FIGS. 9 to 12 relate to a finisher mounting structure for a vehicle air conditioner, which is known from Japanese Utility Model Laid-Open No. 63-157514.

In the figure, reference numeral 1 is an air-conditioning case body, and insertion grooves 2 are formed on both upper and lower sides on the blowing side. A finisher 3 has two pairs of insertion pieces 4 integrally projecting from the upper and lower sides on the air conditioning case body 1 side. A locking claw 5 as an engaging projection is formed in the insertion groove 2 and engages with a locking hole 6 as an engaging recess of the insertion piece 4. Reference numeral 7 denotes a horizontal grill formed on the front surface of the finisher 3 and has a function of rectifying blown air. Reference numeral 8 is a bracket for mounting the air conditioning case body 1 on the instrument panel.

In order to assemble the finisher 3 to the air conditioning case body 1 as shown in FIG. 9, the insert piece 4 as shown in FIG. 10 and FIG. Is engaged with the locking hole 6 and the state shown in FIG. 12 is obtained.

<Problems to be solved by the device> However, when the insert piece 4 is deformed as shown by the chain double-dashed line in FIG. 12 due to initial deformation after molding, twisting of the product due to molding strain, and thermal deformation due to temperature increase in the vehicle, the finisher 3 There was a problem that it came off.

The present invention has been made in view of the above problems of the conventional technique, and an object thereof is to prevent the insert piece of the finisher from coming off the insertion groove even if deformation occurs after molding or after mounting. An object of the present invention is to provide a finisher mounting structure for an air conditioner for a vehicle which does not exist.

<< Means for Solving the Problem >> In order to achieve the above object, the finisher mounting structure for a vehicle air conditioner according to the present invention has an insertion groove for guiding an insertion piece projecting from both sides of the finisher toward the air conditioning case body, A vehicle air conditioner which is formed on both sides of an air conditioning case body on the blow-out side so that the engaging concave portion of the insert piece is fitted into the engaging convex portion of the insert groove, and the insert rises from the outside of the insert groove. It is configured to have at least one elastic stopper having a tapered guide that slightly projects near the tip of the piece.

<Operation> While pushing out the insert pieces on both sides of the finisher, insert the insert pieces into the insert groove of the air conditioning case body, slightly displace the tapered guides of the stoppers outward, and press fit to complete the assembly.

<< Example >> Hereinafter, this invention is demonstrated based on drawing.

1 to 3 show a first embodiment of the present invention. In the figure, 11 is an air-conditioning case body, and two pairs of insertion grooves 12 are formed on both upper and lower sides on the outlet side. A finisher 13 has two pairs of insert pieces 14 integrally formed on both sides of the air conditioning case body 11 from both sides. An engaging claw 15 as an engaging convex portion is formed in the insertion groove 12 and engages with an engaging hole 16 as an engaging concave portion of the insert piece 14. Reference numeral 17 is a horizontal grill formed on the front surface of the finisher 13 and has a function of rectifying blown air. Reference numeral 18 is a bracket for mounting the air conditioning case body 11 on the instrument panel. Reference numeral 19 denotes an elastic stopper, which is a tapered guide which rises from two outer sides of the insertion groove 12 which face each other and slightly protrudes near the tip of the insertion piece 14.
have a.

Therefore, as shown in FIG. 2, the insertion piece 14 is brought close to and inserted into the insertion groove 12, and the tapered guide 19a of the elastic stopper 19 is inserted.
When it is press-fitted while displacing slightly outward, it is assembled as shown in FIG.

4 and 5 show a second embodiment of the present invention. In the figure, reference numeral 29 denotes an elastic stopper, which has a tapered guide 29a that rises from two outer sides of the insertion groove 22 that face each other and slightly overhangs near the tips of the leg piece 29b and the insertion piece 24. On the other hand, a projecting piece 28 having substantially the same height as the leg piece 29b is provided at a portion of the insertion piece 24 facing the elastic stopper 29.
With this configuration, since the elastic stopper 29 can be displaced outward with a slight force when the engaging concave portion 26 is fitted into the engaging convex portion 25, the elastic stopper 29 can be easily inserted, and the protrusion 28 prevents rattling.

6 to 8 show a third embodiment of the present invention.

In the figure, 39 is an elastic stopper, which has a tapered guide 39a rising from the outside on the center line of the insertion groove 32 and slightly protruding to the tip of the insertion piece 34, and further having a through hole 38 immediately below the protruding portion. It has a slide core for the mold that can move forward and backward.

Therefore, when the insertion piece 34 is brought close to the insertion groove 32 as shown in FIG. 6 and pushed in, the engagement concave portion 36 is fitted into the engagement convex portion 35 as shown in FIGS. 7 and 8.

<Effect of the Invention> As described above, the present invention inserts the engaging recesses of the insert pieces protruding from both sides of the finisher into the engaging projections of the insertion grooves formed on both sides of the air conditioning case body. Since at least one elastic stopper having a tapered guide that rises from the outside of the groove and slightly protrudes near the tip of the insert piece is provided, the initial deformation after molding of the finisher,
Even if the insert piece is deformed due to twisting of the product due to molding strain and thermal deformation due to temperature rise in the vehicle, the inserter is completely suppressed by the elastic stopper, so the finisher does not fall off from the air conditioning case body.
