JPS59654Y2 - Reflective shade mounting structure - Google Patents

Description

[Detailed Description of the Invention] The present invention is for attaching a reflective shade to the opening of the device body using a decorative frame.

In the conventional device shown in FIGS. 1 and 2, the decorative frame 2 and the reflective shade 3 are secured with screws, and the decorative frame 2 and the appliance main body 1 are secured with adhesive.

3' is the main piece for mounting, and 4 is a set screw.

This method requires screwing and gluing, which is cumbersome.

Furthermore, since the total of three main pieces 3' need to be arranged symmetrically with respect to the upper and lower center lines, they must be accurately positioned during bonding.

There is no problem if the three main pieces 3' are arranged in a Y-shape or in an inverted Y-shape, but if they are arranged in a diagonal Y-shape, it looks unnatural.

As a result, the product value declines. If the number of main pieces 3' is increased to 6 or more, preferably 8 or more, it will not look unnatural even if the arrangement is asymmetrical, but it will take a lot of effort to screw each one of them. .

This proposal is intended to eliminate the above-mentioned difficulties.

The embodiments shown in FIGS. 3 to 7 will be described below.

1 is a nearly bowl-shaped instrument body. Since this is for a stand, it is fixed to the pillar 5 of the base 6.

Reference numeral 9 denotes a male screw carved on the outer periphery of the opening of the instrument body 1.

Reference numeral 2 denotes a decorative frame made of synthetic resin, which has a shape that covers the thick end face portion and the outer peripheral portion of the opening of the main body of the instrument.

Reference numeral 8 indicates a female thread that is screwed into the male thread 9.

This female thread 8 is divided by two or more grooves running in the direction of thread movement.

The illustrated example is divided into two.

The groove between the dividing screws 8 is very wide.

3 is a reflective shade that receives the light emitted from the light bulb 7 in its center.

This reflective shade 3 has a hemispherical part large enough to easily pass through the opening of the instrument main body and the inside of the decorative frame 2, and a number of main pieces 3' and auxiliary pieces 3'' extending radially from the outer periphery of the hemispherical part. It consists of the ’ part.

The diameter of the hemispherical portion is smaller than the dimension e shown.

The area corresponding to the difference is used as the heat dissipation slit 10.

The base pieces of the main piece 3' and the auxiliary piece 3'' are arranged so that the distance between adjacent pieces is constant.

Further, the base pieces have the same shape except for their length.

Therefore, under a situation where the tip of the base piece is hidden, the base piece appears to have the same shape.

The tip of the base piece is connected to the thick end face of the instrument body 1 and the decorative frame 2.
sandwiched between.

The decorative frame 2 is fixed to the instrument main body 1, and at that time, the reflective shade 3 between them is fixed to the opening of the instrument main body.

The length of the main piece 3' is such that its tip is a female thread 8 in the decorative frame 2.
It is determined to be located between the valley and the mountain.

Therefore, the relationship between the illustrated dimensions a, l), and c is a<C<b.

The length of the auxiliary piece 3'' is determined so that its tip does not touch the thread of the female thread 8.

Therefore, each auxiliary piece 3'' falls within the range of dimension a.

However, it does not fall within the range of dimension e.

By aligning the main piece 3' with the groove between the split screws 8, the reflective shade 3 can be moved without being obstructed by the female screws 8 (each split screw).
It can be placed inside the decorative frame 2.

In this state, surround the reflective shade 3 a little and align the main piece 3' to position 3'' in FIG.

The main piece 3' is thereby located on the back side of the dividing screw 8.

As a result, the reflective shade 3 is temporarily fixed to the decorative frame 2.

This temporary fixing has the effect of smoothing the work of screwing the decorative frame 2 onto the instrument body 1.

This is because there is no need to press the reflective shade 3 by hand at that time.

By providing a foreign stopper for the main piece 3' on the back side of the dividing screw 8, it is possible to prevent the reflective shade 3 from being turned too much during temporary fixation.

The installation work is completed by screwing the decorative frame 2 to which the reflective shade 3 is temporarily fixed to the appliance body 1.

When tightening the screws, the female screw 8 is rotated relative to the male screw 9, so when the installation is complete, the arrangement of each main piece 3' and auxiliary piece 3'' is relative to the upper and lower center line l shown in Fig. 4. It doesn't necessarily have to be symmetrical.

In Fig. 4, it is tilted counterclockwise by about 10 degrees.

However, it doesn't feel unnatural.

This is because there are a large number of main pieces 3' and auxiliary pieces 3'' that look the same.

The role of the auxiliary piece 3'' is to add up the total number of pieces.

The width f of the dividing screw 8 must be smaller than the distance g between adjacent main pieces 3'.

The width f is independent of the auxiliary piece 3''.

However, if there is no auxiliary piece 3'' and all eight pieces are the main piece 3', if there is a female thread 8, it must be divided into many fine threads to maintain the strength of a female thread. However, this complicates the mold for forming the decorative frame 2 and makes cutting the mold difficult.

When the light bulb 7 is turned on, heat is trapped inside the appliance body 1, but some of this heat is discharged outside the appliance through the heat dissipation slits 10 on the outer circumference of the reflective shade.

As described above, according to the present invention, the reflective shade is temporarily fixed to the decorative frame using the female thread for fixing the decorative frame to the appliance body, so the installation work is easy.

In addition, since the decorative frame and reflective shade are attached while rotating, the orientation of the reflective shade is not specified, but we added auxiliary pieces to the outer periphery of the reflective shade and increased the total number of main and auxiliary pieces, so they can be Even if they are not placed symmetrically,
Don't make people feel unnatural.
