JPH1170055A - Fixing structure of inspection hole lid of bathroom - Google Patents

Abstract

PROBLEM TO BE SOLVED: To make fixing operation easier without requiring a metal fitting, etc., for fixing, by engaging an inward facing engaging protrusion protruded from an engaging protrusion of the outer lid of an inspection hole with an outward facing engaging protrusion to fix the outer lid of the inspection hole to the inspection hole. SOLUTION: An inner lid 2 is mounted on the periphery part of an inspection hole of a bathroom and an outward facing engaging protrusion 221 is equipped on an engaging protrusion 22 of the inner lid 2. The engaging protrusion 31 of an inspection hole outer lid 3 is inserted in between the inspection hole periphery wall 14 and the protrusion 22 of the inner lid 2 and an inward facing engaging protrusion 311 of the engaging protrusion 31 of the inspection outer lid 3 is engaged with the outward facing engaging protrusion 221 of the protrusion 22 of the inner lid 2. Since the inspection hole outer lid 3 is fixed thereby, the inspection hole outer lid 3 can be mounted by only inserting in a gap of the inspection hole periphery wall 14. When the inspection hole outer lid 3 is to be mounted, since elastic deformation of the engaging protrusion 31 of the inspection hole outer lid 3 and the engaging protrusion 22 of the inner lid 2 is utilized, dimension accuracy of the engaging protrusion 31 of the inspection hole outer lid 3 and the engaging protrusion 22 of the inner lid 2 is not required to be especially high.

A locking projection 31 of the inspection port outer lid 3 is inserted between the inspection port peripheral wall 14 and the locking projection 22 of the inner lid 2, and an inward locking projection of the locking projection 31 of the inspection port outer lid 3. The inspection door outer lid 3 is fixed by the engagement of the projection 311 and the outward locking projection 221 of the locking projection 22 of the inner lid 2.

In the structure for fixing the inspection port in the bathroom shown in FIG. 1, the locking projection 31 of the inspection port outer lid 3 is inserted between the inspection port peripheral wall 14 and the locking projection 22 of the inner lid 2, and the exterior of the inspection port is removed. When the inward locking projection 311 of the locking projection 31 of the lid 3 and the outward locking projection 221 of the locking projection 22 of the inner lid 2 are engaged, the inspection port outer lid 3 is fixed. Therefore, it can be mounted simply by inserting the inspection port outer cover 3 between the inspection port peripheral walls 14.

When the inspection opening outer cover 3 is attached, the elastic deformation of the locking projection 31 of the inspection opening outer lid 3 and the locking projection 22 of the inner lid 2 is used. The dimensional accuracy and the like between the base 31 and the locking projection 22 of the inner lid 2 do not need to be particularly high.

FIG. 2 is a partially cutaway front view showing another example of the inspection palate fixing structure of the bathroom of the present invention, and FIG. 3 is III-I of FIG.
FIG. 4 is a cross-sectional view taken along line II-IV in FIG. 2.

In the fixing structure for the inspection port of the bathroom shown in FIGS. 2 to 4 according to the present invention, positioning projections 23 project from the side edge and the lower edge of the inner lid 2. The locking projection 22 is provided so as to project from a middle portion of the positioning projection 23, and an outward locking projection 221 is provided at the tip of the locking projection 22.

As shown in an enlarged view in FIG. 5, a peripheral wall 32 is provided on the peripheral edge of the outer lid 3, and the locking projection 31 and the peripheral wall 32 are provided.
And a slit 33 is provided between the two slits 3
The locking projections 31 existing between 3 and 33 are easily deformed,
For example, it can be easily attached to and detached from the inner lid 2 by using the tip of a driver.

The other points are the same as those in the fixing structure of the inspection lid of the bathroom shown in FIG. 1 according to the present invention. The same reference numerals as those used in FIG. 1 are used in FIGS. .

In the fixing structure of the inspection port lid of the bathroom shown in FIGS. 2 to 5, since the positioning projections 23 project from the side edge and the lower edge of the inner lid 2, the inner lid 2 is connected to the inspection port 12. When it is installed on the peripheral wall 1 of the inspection port 12
4, the inner lid 2 can be automatically positioned, and can be attached to a proper position of the recess 13 around the inspection port 12 by the screw screw 21.

FIG. 6 is a front view showing still another example of the fixing structure of the inspection palate of the bathroom according to the present invention, and FIG. 7 is a view VII- of FIG.
It is sectional drawing in the VII line. 6 and 7, a recess 141 is formed in the peripheral wall 14 of the inspection port 12, and the distal end of the locking projection 31 of the inspection port outer lid 3 is locked in the recess 141. The engagement of the projection 311 causes the outer cover 3 of the inspection port to be attached to the peripheral wall 14 of the inspection port 12.
Is to be fixed. Central bulge 2 of inner lid 2 attached to recess 11 of waist wall 1 with screw screw 21
A packing 25 is interposed between 4 and the back surface of the inspection port outer cover 3.

In the fixing structure of the inspection port lid of the bathroom shown in FIGS. 6 and 7, the tip of the locking projection 31 of the inspection port outer lid 3 is outwardly engaged with the concave portion 141 formed in the peripheral wall 14 of the inspection port 12. The inspection cover outer cover 3 is engaged with the stop projection 311.
Is fixed to the peripheral wall 14 of the inspection port 12, when the inspection port outer cover 3 is mounted, the inspection port outer lid 3 is elastically deformed as shown by a two-dot chain line in FIG. It can be installed simply by inserting it.

The attachment of the inspection port outer lid 3 utilizes the elastic deformation of the inspection port outer lid 3 as described above, and therefore, the recess 141 is used.
The dimensional accuracy and the like of the locking projection 31 need not be particularly high.

Although the embodiment of the present invention has been described with reference to the drawings, the configuration of the present invention is not limited to the illustrated embodiment, and design changes within the scope of the present invention are included in the present invention. It is.

For example, in the inspection port cover fixing structure of the bathroom of the present invention shown in FIGS. 6 and 7, if the recess 141 formed in the peripheral wall 14 of the inspection port 12 is a concave groove extending along the vertical direction, the inspection port outer cover 3 can be used. The outward locking projection 311 at the tip of the locking projection 31 of the inspection port outer lid 3 may be engaged with the recess 141 by sliding from above without elastic deformation.

[0028]

According to the first aspect of the present invention, in the fixing structure for the inspection lid of the bathroom, the inward locking projection of the locking projection of the inspection lid is merely engaged with the inner lid by simply inserting the outer lid. Since the engagement protrusion is engaged with the outward locking projection of the stop projection, it is easy to mount the inspection opening outer lid, and when mounting, the elastic deformation of the locking projection of the inspection opening outer lid and the locking projection of the inner lid is used. This eliminates the need for high dimensional accuracy.

According to the second aspect of the present invention, when the inner lid is installed in the inspection opening, the positioning projection contacts the peripheral wall of the inspection opening, and the inner lid is automatically positioned. Since it is possible, the inner lid can be attached to an appropriate position of the inspection port by using a screw screw or the like.

According to the third aspect of the present invention, in the inspection port fixing structure for a bathroom according to the present invention, the outwardly projecting locking projection of the locking projection of the inspection port outer lid is formed by simply inserting the inspection port outer lid. In this case, the inspection cover is easily attached to the recess, and the mounting does not require high dimensional accuracy or the like by utilizing the elastic deformation of the inspection opening.
