Description

[Detailed Description of the Invention] The present invention relates to a rearview mirror mounting device in which a movable hook suspended from the bottom of the stay is engaged with an inverted V-shaped locking piece (hook spring) on the seat plate side. By engaging the movable hook that is swingably hung from the bottom of the stay with the locking piece on the seat plate side, the range of movement of the engaged part is expanded using leverage, and the rearview mirror can be assembled with a light force of 0. and removal can be done accurately and easily.

Among tilting rearview mirrors, those intended to be installed or removed in one-touch manner without using tools such as spanners when attaching the stay part of the mirror to the vehicle body are disclosed in Japanese Utility Model Publication No. 53-11940. Already known from the official gazette. This rod is attached with a hook rod formed with a connecting hook portion on the upper side and a hook portion for temporary fixing on the lower side, and is constantly biased downward by a coil spring. A fixed connecting pin attached to the bottom surface of the stay is engaged with the lower hook portion, and the lower hook portion is configured to be hooked to an engaging protrusion provided on the seat plate. At first glance, this prior example appears to operate smoothly5, but upon experimentation, it became clear that smooth operation could not be expected.

In other words, as shown in Fig. 9, when removing the mirror once installed, the mirror stay S must be tilted backward using the rear end A of the stay as a fulcrum, but even if the stay is tilted, this The hook rod F connected to the stay is simply lifted up, and the lower hook portion F2 formed on the hook rod F does not catch on the ridge D provided on the seat plate C.
It only acts to lift the hook rod against the elasticity of spring E, and does not work. Therefore, in order to hook the hook part F2 on the ridge D, it is necessary to disengage the base of the stay S and the board B and forcefully engage the hook part F2 with the ridge D. In this case, coil spring E
The disadvantage is that the stay is pulled downwards and cannot be engaged as desired because of its elasticity. It was hot. In addition, in the case of the above-mentioned prior art, there are two upper and lower parts on the hook rod.
Since it is necessary to form the hook portion of the step, there is an inconvenience in that the number of processing steps is large and special parts have to be made. Here, the present invention provides a hook to be provided at the bottom of the stay, which is swingably hung from the stay, and correspondingly, an inverted-shaped locking piece is elastically held on the back surface of the seat plate. By engaging the upper end portion with a swingable hook, the back mirror can be attached and detached with a single touch, thereby eliminating all of the above-mentioned drawbacks.

Furthermore, in the present invention, the shape of the locking piece to be engaged with the movable hook attached to the stay side is a simple inverted V-shape, and unlike the conventional type, there are two upper and lower hook parts on the hook rod. This eliminates the hassle of setting up a holder, and also saves labor in terms of manufacturing man-hours. Incidentally, it is possible to form a hook portion on the expanded end portion of the above-mentioned inverted-shaped locking piece to engage it in the diametrical direction of the lower surface of the coil spring. Therefore, before assembly to the automobile body, the bifurcated portions of the inverted V-shaped locking piece are temporarily fixed using the protruding edges formed in the insertion holes of the seat plate, and then the base board and the seat plate are assembled and then the stay plate is attached. After tilting the bracket to the left or right and engaging the movable hook on the lower side of the stay with the locking piece, the locking piece can be removed from the temporary flange to easily and leverage the back mirror. It is designed so that it can be installed with a light amount of force. In addition, when removing it after assembly, tilt the stay to the right or left and hook the engaged movable hook and locking piece to the temporary fixing ridge, thereby making it free. The mirror can be easily removed from the vehicle body by removing the movable hook from the locking piece. The present invention will now be described in detail with reference to the drawings. In the figure, 1 is a stay for a bank mirror, 2 is a car body outer plate such as the front of a car, 3 is a board on which the stay 1 is fitted, 4 is a seat plate that is crimped and fixed to the board 3 on the lower surface of the car body outer plate 2, and 5 6 is a coil spring, 6 is a hook swingably hung from the bottom of the stay 1, and 7 is an inverted V-shaped locking piece hung between the coil spring 5 and the hook 6, and the hook spring is made of steel wire.
