Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a pot with a water level indicator, and particularly to a mounting structure for a water level pipe cover panel thereof.

[Conventional technology]

Conventionally, in a pot having a water level display device, a water level tube cover panel has been attached to the body of the pot with screws.

[The problem that the invention attempts to solve]

The purpose of this invention is to omit the above-mentioned screws, which are one of the factors that increase the cost of the pot, and to attach the water level tube cover panel to the body of the pot by forced fitting.

[Means for solving problems]

In order to solve the above-mentioned problems, this invention provides a pair of engagement protrusions each on the rear edge of both side plates of the water level pipe cover panel in three stages, upper, middle and lower, and at least the upper stage of these engagement protrusions is provided. and a hook-shaped bent part bent in the same direction in the length direction of the water level pipe cover panel on the lower engagement protrusion, corresponding to the engagement protrusion on each of the above stages, and longer in the vertical direction than the engagement protrusion. Each pair of insertion holes are formed in the pot body, and the distance between the middle insertion holes is formed to be slightly smaller than the distance between the middle engagement protrusions, and the hook shape is formed on the outer side of the middle insertion hole. An enlarged part of the insertion hole is formed by shifting toward the bending direction of the bent part, and a small protrusion is formed close to one side of the back surface of the upper and lower insertion holes on which the hook-shaped bent part of each of the upper and lower engagement protrusions rides. The structure is as follows.

[Effect]

The water level tube cover panel described above is attached by inserting the upper, middle, and lower engaging protrusions into corresponding insertion holes on the pot body side. In this case, the middle engagement protrusion is inserted by grasping the center part of the side plate of the water level tube cover panel with two fingers, bending it inward somewhat, and narrowing the interval. After insertion, move the water level tube cover panel either up or down in one direction, that is, upward if the bent direction of the hook-shaped bent portion is upward, or downward if it is downward, so that each of the upper and lower hook-shaped bent portions is aligned with the insertion hole. Place it on the small protrusion on the back side and bring the water level pipe cover panel and the pot body into close contact.

Next, when the fingertips gripping the center portion of the side plate of the water level tube cover panel are released, the middle engagement protrusion fits into the enlarged hole of the middle insertion hole to prevent vertical displacement.

〔Example〕

The pot 1 of the embodiment is equipped with a water level display device consisting of a water level pipe 2 and a water level pipe cover panel 3.

The water level pipe cover panel 3 includes a front plate 5 having a water volume display window hole 4, and side plates 6 slightly expanding laterally.
It is a plastic molded product in the shape of a vertically elongated box with an open back and upper and lower end plates 7 and 8.

On the inner surface of the rear edge of the both side plates 6, the upper stage,
Pairs of engagement protrusions 9, 9', 9'' are formed in each of the three middle and lower tiers.These engagement protrusions 9, 9', 9'' are hook-shaped bent portions 1 bent upward.
0 (Figures 4 and 5).

On the other hand, the pot body 12 is formed with insertion holes 13, 13' corresponding to the upper and middle engaging protrusions 9, 9', and the insertion holes corresponding to the lower engaging protrusions 9'' are formed at the water level. It also serves as the tube insertion hole 15.

The vertical lengths of these insertion holes 13, 13', 15 are formed to be somewhat longer than the respective engaging protrusions 9, 9', 9'' in the vertical direction.

Further, as shown in FIG. 4, the spacing between the middle insertion holes 13' is narrower by a certain distance a inwardly than the spacing between the middle engagement protrusions 9. Therefore, by bending the both side plates 6 of the water level tube cover panel 3 inward and shifting the position of the engaging protrusion 9' from the position shown by the dashed line to the position shown by the solid line, the engagement can be achieved. The protrusions 9' can be arranged at intervals equal to the intervals of the insertion holes 13'.

An enlarged part 16 is formed in the upper part of the outer side of the middle insertion hole 13', that is, in a part offset in the direction of bending of the hook-shaped bent part 10, and the hole is in the shape of an inverted L as a whole. The enlarged part 16 is formed in a size that allows the engagement protrusion 9' to be inserted therein, and a support plate 17 that protrudes inward is provided on the lower side of the enlarged part 16.

In addition, the pot body 12 is inwardly hammered out to form small protrusions 1 at the upper portions of the insertion holes 13, 13', and 15.
8, 18', 18''. These small protrusions 18, 18', 18'' form engaging protrusions 9, 9',
9'' into these insertion holes 13, 13', and 15, and when the water level tube cover panel 3 is pushed upward, the inner surface of the hook-shaped bent portion 10 rides up and protrudes to a height where it can be strongly pressed. ing.

In addition, in FIG. 3, 19 is a pot shoulder body 20.
A water level tube insertion hole is formed in the pot shoulder body 20, and a protruding edge 21 is formed on the front surface of the pot shoulder body 20, with which the upper surface of the water level tube cover panel 3 comes into contact.

The embodiment of this invention has the above-mentioned configuration, and its operation will be explained next.

Since the water level pipe cover panel 3 is made of plastic, if you grasp the center part of both side plates 6 with your fingertips and apply force, both side plates 6 will bend inward, and the engaging protrusion 9' in the center will move inward. deviates by a constant dimension a. At this time, the upper and lower parts of both side plates 6 do not bend, so
The spacing between the other engaging protrusions 9', 9'' remains unchanged.

Therefore, after inserting the upper and middle engaging protrusions 9, 9' into the corresponding insertion holes 13, 13', and inserting the lower engaging protrusion 9'' into the water level pipe insertion hole 15, Push up the cover panel 3 along the pot body 12. Then, the inner surfaces of the hook-shaped bent portions 10 of each of the engaging protrusions 9, 9', 9'' ride on the small protrusions 18, 18', 18'' and are pressed together. As a result, the water level pipe cover panel 3
is in close contact with the pot body 12.

Furthermore, when the fingertips gripping the side plates 6 are released, the deflection of the side plates 6 disappears, so the middle engagement protrusion 9' enters the enlarged portion 16, and at the same time the support plate 1
7 (Figures 8 and 9). This prevents the water level tube cover panel 3 from shifting upward or downward.

Incidentally, when removing the water level tube cover panel 3, the above operation may be performed in reverse.

In the case of the above embodiment, the middle engagement projection 9' is also provided with a hook-shaped bent portion 10, and a corresponding small projection 18' is provided on the pot body 12 side, so that the water level pipe cover panel 3 is Although the adhesion is further improved, the adhesion can also be sufficiently achieved by the hook-shaped bent portions 10 of the upper and lower engagement protrusions 9, 9'' and the corresponding small protrusions 18, 18''. The hook-shaped bent portion 10 and small projection 18' of the middle engagement projection 9' may be omitted. Omitting the hook-shaped bent portion 10 means omitting the upper portion of the portion indicated by the dashed line A in FIG. In this way, the middle engagement protrusion 9' without the hook-shaped bent part 10 becomes an engagement protrusion 9' that simply projects horizontally, and is supported by the support plate 17 by being inserted into the enlarged part 16, and the water level It acts to prevent the tube cover panel 3 from moving downward.

[Effect of idea]

As mentioned above, this design provides hook-shaped bent parts bent in the same direction on the upper and lower engaging protrusions provided on the water level pipe cover panel, and each bent part is bent over the small protrusion on the back side of the insertion hole in the pot body. By placing the water level pipe cover panel on the pot body, the water level pipe cover panel can be brought into close contact with the pot body.

In addition, by utilizing the deflection of the side plate to engage the middle engagement protrusion with the enlarged portion of the pot body insertion hole, it is possible to prevent the water level tube cover panel from shifting in the vertical direction.

Therefore, according to this invention, the water level pipe cover panel can be easily and securely installed without using any screws, and when repairing horizontal pipes, it can be easily done by using the deflection of the side plate. This has the effect of allowing the water level pipe cover panel to be removed.
