Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a mounting structure for decorative parts such as automobile interior parts, and more particularly to a mounting structure for decorative parts that can be mounted very easily.
[0002]
[Prior art]
A shift indicator for indicating the current position of the shift lever is arranged around the shift lever for a console of an automobile having an automatic transmission, and a decorative frame is interposed between the shift indicator and the console cover. The design is improved by covering the gap at the boundary. This decorative frame body is generally formed by resin molding, and is subjected to metal plating treatment in order to improve design properties.
[0003]
A through hole larger than the size of the shift indicator is formed in the console cover. First, the decorative frame body is fixed to the console cover by sandwiching the periphery of the through hole. Then, the assembly is completed by assembling a console cover having a decorative frame on the console on which the shift lever protrudes and the shift indicator is mounted.
[0004]
By the way, when fixing the decorative frame body to the peripheral edge portion of the through hole of the console cover, it is necessary to absorb a dimensional error or the like so that no gap is generated. Therefore, conventionally, a mounting structure as shown in FIGS.
[0005]
In this mounting structure, a decorative frame 100 and a fixing member 200 are used. A holding projection 101 having a U-shaped cross section is formed to protrude from one end of the decorative frame 100 on the back side, and a plate-shaped welding projection 102 is formed to protrude from the other end. The fixing member 200 is formed in a rod shape having a substantially L-shaped cross section along the other end of the decorative frame 100, and a through hole 201 is formed at a position corresponding to the welding protrusion 102. By inserting the welding protrusion 102 into the through hole 201, the other end portion of the decorative frame body 100 and the fixing member 200 form a U-shaped holding portion.
[0006]
The opposite ends of the peripheral edge of the through hole of the console cover 300 are held between the holding protrusion 101, the other end of the decorative frame 100 and the holding member 200 having a U-shaped cross section. Then, the decorative projection 100 is fixed to the console cover 300 by fixing the decorative frame 100 and the fixing member 200 by heat caulking the welding projection 102 protruding from the through hole 201.
[0007]
According to this mounting structure, the decorative frame 100 can be easily fixed to the console cover 300 without a gap by forming the decorative frame 100 larger than the size of the through hole of the console cover 300. Can do.
[0008]
Japanese Utility Model Laid-Open No. 5-054805 discloses a structure in which an interior part having a U-shaped cross section is attached to a vehicle body sheet metal using spring elasticity of its side wall. According to this mounting structure, since all can be formed from resin without using a metal pin or the like, no abnormal noise is generated due to rust or interference. It can also be removed.
[0009]
[Problems to be solved by the invention]
However, the mounting structures shown in FIGS. 8 and 9 have a problem that the number of man-hours is large because a heat caulking process is required.
[0010]
Furthermore, the decorative frame 100 is often subjected to metal plating for the purpose of providing a sense of unity with the shift indicator. However, if metal plating is applied up to the welding protrusion 102, welding becomes difficult. Therefore, man-hours for masking and plating the welding protrusions 102 and peeling the metal plating formed on the welding protrusions 102 are required, which further increases the man-hours and increases the cost.
[0011]
In addition, a metal-plated resin decorative part is too rigid to be attached using spring elasticity as disclosed in Japanese Utility Model Publication No. 5-054805.
[0012]
The present invention has been made in view of such circumstances, and an object of the present invention is to make it possible to easily attach a decorative part subjected to metal plating without requiring a welding process.
[0013]
[Means for Solving the Problems]
The feature of the decorative part mounting structure of the present invention that solves the above-mentioned problems is that the decorative part has a design surface on the front surface and has a hard decorative part having a locking projection protruding from the back side, and a resin made to be engaged and fixed to the locking member. The locking member and at least a part of the mounting member in the form of a plate are decorated in a state of being in contact with the surface of the mounting member by sandwiching a part of the mounting member between the decorative part and the locking member. A mounting structure for a decorative part to which the part is attached,
The locking projection is composed of a substantially L-shaped first projection consisting of a neck protruding from the back of the decorative part and a head bent from the neck, and a second protrusion protruding from the back of the decorative part,
The locking member includes a first through hole that protrudes through the head of the first protrusion and protrudes toward the back surface, a flexure that can be elastically deformed by the second protrusion contacting and pressing, and the locking member as a decorative part. has a locking recess for engaging the sliding movement is allowed first protrusion rides over the second projections flexures when the relative sliding movement of the first through-hole with respect to,
The relative movement of the locking member and the decorative member in the sliding direction is restricted by engaging the second protrusion with the locking recess, and the head of the first protrusion protrudes from the first through hole and engages with the back surface of the locking member. By combining, the movement in the direction in which the decorative member and the locking member are separated is restricted.
[0014]
The decorative member can be a plated resin part. The second protrusion has a substantially triangular shape having a locking surface extending substantially at right angles from the back surface of the decorative part and a tapered surface extending inclined from the front end of the locking surface in the direction in which the head extends. It is desirable to have a second tapered surface that is in sliding contact with the surface.
[0015]
DETAILED DESCRIPTION OF THE INVENTION
In the decorative part mounting structure of the present invention, the locking protrusion is mechanically engaged with the decorative part, so that the locking member is fixed to the decorative part. The decorative part and the locking member hold the end of the mounted member. The decorative part is attached to the member to be attached by clamping. Therefore, the heat caulking process is not necessary, and the number of assembling steps can be reduced. In addition, since a heat caulking process is not required, a masking or metal plating peeling process is not required even for a metal-plated decorative part. As a result, the number of man-hours can be further reduced, and the cost can be greatly reduced.
[0016]
In order to form the decorative part mounting structure of the present invention, first, the decorative part is disposed along a part of the plate-like shape of the member to be mounted, and the locking member is disposed on the back side. Then, the head of the L-shaped first protrusion is inserted through the first through hole of the locking member and penetrated, and the second protrusion is brought into contact with the bending portion. Subsequently, the locking member is moved relative to the decorative part, and the neck portion of the first protrusion is slid in the first through hole. At this time, the bent portion is elastically deformed by the pressing of the second protrusion, and the second protrusion gets over the bent portion and engages with the locking recess. Then, the head portion of the first protrusion protrudes from the first through hole, contacts the back surface of the locking member at the peripheral edge portion thereof, and the peripheral edge portion of the first through hole is sandwiched between the back surface and the head portion of the decorative component; Become.
[0017]
Therefore, when the second protrusion is engaged with the locking recess, the relative movement of the locking member and the decorative member in the sliding direction is restricted, and the head of the first protrusion is the peripheral portion of the first through hole and the back surface of the locking member. Since the movement in the direction in which the decorative member and the locking member are separated by being engaged with each other is restricted, the decorative member and the locking member are integrally fixed. In this state, a part of the plate shape of the attached member is sandwiched between the decorative member and the locking member, so that the decorative member can be easily attached to the attached member without the need for heat caulking or the like.
[0018]
The decorative member is not limited to the decorative frame of the shift indicator described in the prior art, and can be various parts used in the interior and exterior of automobiles, ornaments, design marks for home appliances, and the like. Moreover, the material should just be a hard thing which a latching protrusion does not deform | transform, Hard resin, such as ABS, resin by which metal plating, a metal, etc. can be used. If the decorative member is formed from a metal-plated resin, the design is enhanced and the metal plating makes it harder. Therefore, the deformation of the locking protrusion can be further prevented compared to the case of the resin alone, and the decorative member is decorated. It is possible to further prevent a problem that the member comes off.
[0019]
The first protrusion and the second protrusion of the decorative member are formed integrally with the main body of the decorative member. The position is appropriately determined according to the shape of the decorative member. For example, in the case of the above-mentioned decorative frame, it can be formed on one side or on the back side of two sides facing each other, and can also be formed on all four sides. In the case of an ornament or the like, it can be formed at the center of the back surface. The positional relationship between the first protrusion and the second protrusion is not particularly limited. However, in the case of a decorative part having a narrow width such as the above-described decorative frame body, it may be arranged on a straight line parallel to the relative movement direction described later. desirable.
[0020]
The locking member can be formed of a resin such as ABS, PP, PA, etc., since the bent portion is elastically deformable and requires a certain degree of strength.
[0021]
The second protrusion of the decorative member has a shape that can press the bending portion with the force of relative movement. For example, a substantially triangular shape having a locking surface extending substantially at right angles from the back surface of the decorative part and a tapered surface extending in a direction parallel to the direction in which the head of the first protrusion extends from the tip of the locking surface may be formed. Desirably, the bent portion of the locking member preferably has a second tapered surface that is in sliding contact with the tapered surface. In this way, since the taper surface of the second protrusion and the second taper surface of the bending portion are in sliding contact with each other during the sliding movement, the bending portion can be stably elastically deformed by the sliding movement force. It is possible to prevent the engagement from becoming unstable due to permanent deformation of the portion. Further, since the locking surface of the second protrusion is engaged with the end of the bending portion, the relative movement between the decorative member and the locking member after attachment can be further prevented.
[0022]
