Abstract

PURPOSE:To prevent an escassion from being made with small wall thickness by furnishing a boss in contact with the rear of a door trim and a pawl protruding from a door trim hole to the surface at the perimeter of the front end of a handle base, and providing a pawl detent protruding toward the hole at the perimetric edge of the escassion. CONSTITUTION:A plurality of bosses 13 extending laterally to the left and right peripheries are formed at the side wall 9 of a handle base 5 and are put in contact with a door trim 17. Approx. perpendicularly to the bosses 13, a pawl 15 is provided protruding therefrom being directed toward an opening 19 in the door trim 17. At the frame-shaped inner edge of an escassion 1 a tail part 25 is formed, which can contact the front end 11 of the handle base 5, while a detent part 29 which contacts the surface 27 of the door trim 17 when mounted and which admits detantion of a hook of the pawl 15, is formed at the peripheral edge in frame form. This constitution prevents the appearance from worsening due to thinned wall of the escassion 1 at the time of its shaping because of missing of any pawl or boss.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention mainly relates to a mounting structure for a handle escutcheon used for a door inside handle.

(Conventional technology) Conventional door inside handle escutcheon 101
The mounting structure of the escutcheon 101 is shown in a cross-sectional view in FIG. 3, and FIG. 4 is a perspective view of the escutcheon 101. Third
The cross-sectional view of the figure is III-II of the door 102 shown in FIG.
This is a cross section taken along the line I, and FIG. 6 shows an exploded perspective view of the mounting structure seen from the door inner panel side. See Utility Model Publication No. 64-1887 for a similar structure.

A handle base 105 on which the door inside handle 103 is rotatably provided is fixed to the door inner panel 106 of the door body, and the door inside handle 103 is inserted into the vehicle interior through a door inside handle protrusion hole 111 provided in the door trim 109. I'm looking into it. The gap between the periphery of the front end 115 of the handle base 105 and the hole 111 is covered by the escutcheon 101.

This escutcheon 101 is made of synthetic resin, and has a plurality of resilient claws 117 projecting rearward from the back surface.

At multiple locations around the hole 111 of the door trim 109,
A claw insertion hole 119 into which the claw 117 can be inserted is provided.

To attach the escutcheon 101, first attach the handle base 105 to the door inner panel, and then push the respective claws 117 of the escutcheon 101 into the corresponding claw insertion holes 119. The inclined portion of the claw 117 touches the inner peripheral edge of the claw insertion hole 119 and the claw 117 is pushed open.
It is elastically locked to the back surface 121 of the door trim 109 on the inner circumference of the door trim 109 . At this time, the outer peripheral end 125 and the rear end 127 of the escutcheon 101 come into contact with the surface of the door trim 109 and the front end 115 of the handle base 105, respectively, and the escutcheon 101 is attached to the door trim 109.

In this attached state, the hole 111, the claw 117, and the claw insertion hole 119 are hidden by the escutcheon l○1.

In the attached state, the door inside handle 103 is configured to interlock with a door lock mechanism (not shown) attached to the door body 107.

(Problems to be Solved by the Invention) However, the conventional mounting structure for the escutcheon 101 has the following problems.

(a) During molding, sink marks are likely to occur near part A on the surface of the root at the attachment of the claw 117, which weakens the engagement rigidity of the claw 117 and deteriorates the appearance.

That is, since the claw 117 extends from the back surface of the escutcheon 101, during molding, the molten resin flows to form the claw 117, so that the claw 117 is attached near part A on the surface of the root. In addition, the escutcheon 101 has an E-shaped cross section due to the rear end 127, the claw 117, and the outer end 125, making it difficult for the melted resin to flow to the corners. The surrounding area will lose weight.

(b) It is difficult to remove from the door trim 109.

That is, since the hook portion of the claw 117 is locked to the back surface 121 of the door trim 109, the tool for removing the hook portion of the claw 117 from the back surface 121 of the door trim 109 cannot be used from the front surface side of the door trim 109 on the outer periphery of the escutcheon 101. It is difficult to enter, and the operation of opening the claw 117 toward the outer circumference is extremely difficult.

If, for example, a flathead screwdriver is inserted between the rear end portion 127 and the front end portion 115 that are in contact with each other and pried, the handle base 105 is hard, so it is difficult to insert the screwdriver, and a crack will occur near the A section of the escutcheon 101. (There is a fear that this may occur.

This invention solves these problems of conventional mounting structures and proposes a mounting structure for a handle escutcheon that is devised so that sink marks do not occur during molding and removal from the door trim is easy. The purpose is to

[Structure of the Invention (Means for Solving the Problem) A handle base of an inside door handle is fixed to a door inner panel, and the inside door handle is made to look into the vehicle interior through a hole for protruding the inside door handle formed in the door trim. A space between the hole in the door trim and the handle base is covered with an escutcheon, a protrusion that contacts the back surface of the door trim and a claw protruding from the hole toward the front surface of the door trim are provided around the front end of the handle base, and an outer peripheral edge of the escutcheon is provided. The escutcheon is provided with a locking portion that protrudes toward the hole and locks the pawl while abutting against the surface of the door trim.

(Function) The claws and protrusions necessary to lock the escutcheon to the door trim are formed on the handle base and are no longer necessary for the escutcheon. The fear of losing weight and worsening its appearance has been resolved.

To install the escutcheon, insert the locking part of the escutcheon between the pawl and the door trim so that the rear end of the escutcheon faces the front end of the handle base, and the pawl will press the locking part to the surface of the door trim. The installation is then completed.

To remove it, simply insert a screwdriver or the like between the escutcheon and the door trim and press the nail. The door trim is soft and allows you to easily insert a screwdriver etc.

(Example) Next, one embodiment of the present invention will be described based on the drawings.

FIG. 1 shows a longitudinal sectional view of the mounting structure, and FIG. 2 shows a perspective view of the escutcheon 1. FIG. 1 is a sectional view taken at the same position as FIG. 3, and the structure is basically the same as that shown in the exploded perspective view shown in FIG.

The handle base 5 on which the door inside handle 3 is rotatably provided has a box shape with an open front, and includes a bottom 7, a side wall extending from the bottom 7, and a side wall 9 near the front end 11 to the bottom 7. It is composed of a plurality of protrusions 13 that extend outward from the left and right in parallel with the , and claws 15 that protrude from each protrusion 13 at a substantially right angle toward the opening.

The protrusion 13 may be provided all around the handle base 5 or may be provided partially.

This handle base 5 is fixed to a door inner panel (not shown) with screws or the like, and in this state, the protrusion 13 is in contact with the back surface of the door trim 17, and the hook of the claw 15 protruding from the hole 19 and the surface 27 of the door trim] 7 are in contact with each other. A gap will be formed in between.

The escutcheon 1 is made of synthetic resin and has a rectangular frame shape when viewed from the front, and the vertical cross section of the sides is formed into a channel shape.

The inner edge of the frame shape is formed with a rear end portion 25 that can sometimes come into contact with the front end 11 of the handle base 5 when attached, and the outer peripheral edge of the frame shape has a rear end portion 25 that can sometimes come into contact with the surface 27 of the door trim 17 when attached. In addition, a locking portion 29 is formed in which the hook of the claw 15 can be locked. The locking portion 29 may be provided around the entire circumference or may be provided partially.

The handle base 5 is fixed to the door inner panel,
In this state, the door inside handle 3 is coupled to a door lock 81 structure (not shown) so as to be interlocked with the door lock 81 structure.

Next, the installation and removal operations of the escutcheon 1 will be explained.

The rear end part 25 of the escutcheon 1 is opposed to the front end part 11 of the handle base 5 already fixed to the door inner panel so as to come into contact with it, and the escutcheon 1 is pressed against the handle base 5 as it is. When the locking portions 29 of the escutcheon 1 push the pawls 15 away while contacting the slopes of the pawls 15, and the locking portions 29 of the escutcheon 1 are positioned in the gaps between the hooks of each pawl 15 and the surface 27 of the door trim 17, the pawls 15 become elastic. The locking portion 29 is elastically pressed against the surface 27 of the door trim 17 by the claw 15. At the same time, the rear end 25 of the escutcheon 1 is pressed against the front end 11 of the door base 5, and the escutcheon 1 is pressed against the front end 11 of the door base 5.
7 and the handle base 5.

The escutcheon 1 fixed in this manner hides the hole 19 and the claw 15 of the door trim 17.

To remove the escutcheon 1, insert something like a flathead screwdriver between the surface 27 of the door trim 17 and the locking part 29 of the escutcheon 1, push the claw 15, and then push the locking part 29 between the claw 15. It ends when you remove it from the hook.

This operation can be performed from around the escutcheon 1, and since the door trim 17 is soft, a screwdriver or the like can easily enter it, making the removal operation extremely easy.

Claw 15 and protrusion 1 for attaching escutcheon l
3 is formed on the handle base 5 and there is no need to provide it on the escutcheon 1, so when these claws 15 and protrusions 13 are formed during resin molding, the flesh of the escutcheon becomes thinner and the appearance deteriorates. The conventional problem of escutcheon 1 has been solved and has sufficient decorative functions.
It becomes. Moreover, the engagement rigidity of the claw 15 is not impaired.

[Effects of the Invention] As is clear from the above, according to the configuration of this invention,
The claws and protrusions necessary to lock the escutcheon to the door trim are formed on the handle base, and it is no longer necessary to form them on the escutcheon side, so the material for molding these claws and protrusions is saved. This eliminates the disadvantages of thinning of the surface meat of the escutcheon, resulting in poor appearance, and loss of retention rigidity of the nails, and provides a sufficient decorative function.

With the escutcheon attached to the door trim, you can insert a tool between the outer circumference of the escutcheon and the surface of the door trim to release the claw, making removal extremely easy and improving work efficiency. did.
