Description

[Detailed description of the invention] This invention is an automotive radiator in which the brackets installed on both sides of the radiator core can be used interchangeably for those equipped with a shutter and those without a shutter. Regarding the structure of the shutter installation part.

Conventionally, a shutter S installed in an automobile radiator has mounting pieces c, c fixed to brackets b, b' installed at both ends of the radiator core a, as shown in FIGS. 1 and 2. It is attached by hanging the shaft e in the hanging slits d and d' of ',
When in use, the operating string f is pulled in, and the brackets b,
Latching piece g, g' or h fixed to the lower part of b',
A latching pawl j is adapted to be latched in a latching groove i of h'.

By the way, some automotive radiators are equipped with a shutter, such as those used in cars for cold or high-temperature regions, and others are not equipped with a shutter. The brackets b and b' are not separately made with and without a shutter, but are equipped with a shutter, that is, the mounting pieces c and c' and the hanging pieces g, g' and h. ，
Only brackets b and b', which are provided with h', are made, and these are used in common for both those equipped with a shutter and those without, thereby preventing the increase in factors and making parts management easier. .

However, on the other hand, the brackets b and b' installed on a radiator not equipped with a shutter must be very expensive, which inevitably increases manufacturing costs. Incidentally, since the mounting pieces c, c' and the hanging pieces g, g', h, h' are fixed to the brackets b, b' by welding means such as spot welding, a shutter is not installed. Brackets b and b' result in a large amount of waste in addition to material and manufacturing costs.

Therefore, this invention provides a structure for a shutter installation part in an automobile radiator that can solve the above-mentioned problems.

An embodiment of this invention will be described below with reference to FIGS. 3 and 4.

In the figure, 1 and 1' are brackets fixedly installed on both sides of the radiator core 2, and these brackets 1 and 1' have shutter installation walls 3 and 3' that are bent parallel to the front of the radiator core 2. , has an L-shaped cross section.

And, on the shutter installation walls 3, 3',
As shown in FIG. 5, rectangular window holes 4, 4' for attaching the shutter mounting ring are provided at the upper part, and rectangular window holes 5, 5' and 6 for the shutter hook hook pieces are provided at the lower part.
6' are formed at regular intervals.
Each of the window holes 4 to 6' is provided with an H-shaped cut 7, as shown in FIG.
It is formed by pressing the lower tabs 8, 8' and bending them at right angles inward from the broken line.

Reference numeral 9 denotes a shutter mounting ring which is inserted into the window holes 4, 4' and is made of a single metal thin plate material such as a thin brass plate.As shown in FIG. A retaining curl 1 is continuously formed around the periphery of this, and a retaining curl 1 is formed at each insertion end.
Two facing plates 12,1 having 1,11'
2'. The facing plates 12, 12' are arranged at a constant interval, and the width of the interval is set to be considerably larger than the vertical width of the window holes 4, 4'. Therefore, in order to attach this shutter mounting ring 9 to the window holes 4, 4', the opposing plates 12, 1 are required.
2' is compressed while inserting the insertion part 13 into the window holes 4, 4'. When the insertion is completed,
The facing plates 12, 12' are brought into pressure contact with the upper and lower ear pieces 8, 8' of the window holes 4, 4', and at the same time, their retaining curls 11, 11' are brought into contact with the inner ends of the upper and lower ear pieces 8, 8'. It is latched. A shutter bobbin 15, which houses a wound shutter 14 therein, is fitted under pressure into the annular main portion 10 of the shutter attachment ring 9.

Reference numeral 16 denotes a shutter claw hooking piece that is inserted into the window holes 5, 5' and 6, 6' and is made of a single thin metal plate material such as a thin brass plate, similar to the shutter mounting ring 9. 8, the cross section U has a semicircular stopper groove 17 on the lower surface.
A letter-shaped main part 18, and two facing plates 21, 2 whose open ends extend through a step part 19 and have retaining curls 20, 20' at their insertion ends, respectively.
1'. The facing plates 21, 21' are arranged at a constant interval, and the width of the interval is set to be considerably larger than the vertical width of the window holes 5, 5' and 6, 6'. Therefore, in order to attach this shutter claw hooking piece 16 to the window holes 5, 5' and 6, 6', the opposing plates 21, 21' are compressed and the insertion portion 22 is inserted into the window holes 5, 5' and 6'. , 6', but when the insertion is completed, the facing plate 21,
21' is pressed against the upper and lower ear pieces 8, 8' of the window holes 5, 5' and 6, 6', and at the same time its retaining curls 20, 20' are pressed against the inner ends of the upper and lower ear pieces 8, 8'. It is hung on. And the shutter claw hooking piece 16
In the stop groove 17 of the main part 18, there is a radiator core 2.
When closing, the shutter pawl 24 of the winding shutter 14 pulled out from the shutter bobbin 15 by the operating string 23 is latched.

In summary, the structure of the shutter installation part in the automobile radiator according to this invention is such that brackets having shutter installation walls bent parallel to the front of the radiator core are installed on both sides of the radiator core, and The insertion part of the shutter installation element is formed in a predetermined part of the shutter installation wall in a through-hole for mounting the shutter installation element. Since the installation element is installed by inserting the insertion part in a compressed state, the shutter installation element can be freely attached and removed by simply compressing the insertion part, and the installation of the shutter installation element is easy. If a bracket is configured that has a shutter installation wall with a penetration part formed therein, this bracket can be installed as is for a radiator that is not equipped with a shutter, and for a radiator that is equipped with a shutter, as described in the embodiment. By inserting and installing the shutter installation element, which serves as the shutter attachment ring and the shutter hook hook piece, into the installation penetration part, the bracket can be installed as a bracket for the shutter equipment, and the brackets can be used interchangeably. be able to.

Therefore, as with the conventional structure, there is no need to prepare separate brackets for those equipped with a shutter and those without, making parts management easier.
In models without a shutter, there is no need to attach a shutter installation element unlike in conventional structures, resulting in a significant cost reduction.

In addition, with this invention, the shutter installation element can be installed by simply compressing the insertion part and inserting it, and moreover, it can be installed securely by its own elastic force and retaining mechanism. be able to.

Furthermore, since the shutter installation element used in this invention can be constructed by molding a single thin metal plate as in the embodiment, it is less expensive than the conventional structure constructed from a thick plate. It has many practical benefits such as being able to be manufactured, and is extremely valuable industrially.

Note that this invention is not limited to the structure of the embodiment. For example, the mounting penetration part of the shutter installation element formed in the shutter installation wall of the bracket may be a slit opening at the side edge of the shutter installation wall, as shown in FIG. 25, and the shutter installation element may be inserted from the side edge direction, and the retaining portion provided at the insertion end of the insertion portion of the shutter installation element may be a protrusion 26 as shown in FIG. Regarding the configuration, various design changes can be made without departing from the technical idea stated in the claims of the utility model registration.
