点があった。By the way, in the conventional wall inspection port shown in FIG. 13, deterioration of appearance due to exposure of the hinge member 191 can be solved. However, if the hinge member 191 is arranged on the inner side of the inner rim 130 of the outer frame 121, the gap S between the inner rim 130 of the outer frame 121 and the inner frame 151 is increased. You have to make it bigger. That is, in the conventional inner frame 151, the opening / closing trajectory when the inner frame 151 is opened / closed is such that the deeper edge 153 a of the base wall 153 of the inner frame 151 is the largest, and the deeper edge 153 a The gap S between the lining protruding edge 130 of the outer frame 121 and the front edge 153b of the base wall 153 of the inner frame 151 must be set large in accordance with the opening / closing locus to be formed. For this reason, there is a problem that the gap S between the inner rim 130 of the outer frame body 121 and the inner frame body 151 becomes large, and the gap S deteriorates the appearance.

縁の張り出し寸法が設定されている。In order to achieve the above object, a wall inspection port according to the present invention is provided with an outer frame attached to an opening formed in a wall of a building, and an outer frame thereof. An inner frame body that is openably and closably attached to the opening of the body by hinge means having a hinge axis, wherein the outer frame body includes:
A base wall portion substantially parallel to an inner side surface of the opening of the wall, and an outer projection edge projecting from a front end of the base wall toward at least a front surface of the wall; The body has a base wall that is substantially parallel to the base wall of the outer frame, and an overhanging edge that extends from the front end of the base wall toward at least the opening of the outer frame. The hinge means is provided in a space defined by a mutual base wall portion of the outer frame body and the inner frame body and an overhanging edge of the inner frame body, and the inner frame body is centered on a hinge axis of the hinge means. The outer projection of the inner frame body does not protrude outside the opening / closing locus formed by the outer end of the outer projection edge of the inner frame body when the inner frame body is opened and closed. The overhang dimension of the edge is set.

とができる。Therefore, when the inner frame is closed with respect to the outer frame, the hinge means is provided in the space defined by the base wall of the outer frame and the base wall of the inner frame and the overhanging edge. The hinge means is concealed without being exposed to the outside. When the inner frame is opened and closed about the hinge axis of the hinge means with respect to the outer frame, all of the inner frame is moved with respect to the outside of the opening / closing locus formed by the outer end of the extended edge of the inner frame. Since the overhanging dimension of the outer projection edge of the inner frame is set so that the portion does not protrude to the outside, especially at the free end side of the inner frame, the inner frame is opposed to the opening of the outer frame. The body is satisfactorily opened and closed without collision, and the gap between the opening of the outer frame and the overhanging edge of the inner frame can be made as small as possible.

の向上を図ることが可能となる。When opening and closing the inner frame 51 with respect to the outer frame 21, the locking device 100 is first unlocked. In this unlocked state, the inner frame 51 is opened and closed with respect to the outer frame 21 about the hinge shaft 92. When the inner frame body 51 is opened and closed around the hinge shaft 92, all of the inner frame body 51 is moved outside the opening / closing locus formed by the peripheral edge of the outer projection 59 of the inner frame body 51. Part, for example, base wall 5
The extension of the outer projecting edge 59 of the inner frame 51 is set so that the folded edge 58 at the rear end of the inner frame 3 does not protrude outside the opening / closing locus. For this reason, in particular, on the free end side of the inner frame member 51, that is, on the left inner frame member 52d side, the folded edge 58 of the left inner frame member 52d is opposed to the lining projection 30 of the left outer frame member 22d. It is possible to open and close satisfactorily without collision and by reducing the distance between the inner and outer frames. As a result, it is possible to improve the appearance by making the gap between the rim 30 of the outer frame 21 and the rim 29 of the inner frame 51 as small as possible.

In order to prevent the outer projection edge 59 of the right outer frame member 22c from colliding with the right outer frame member 22c, the inner extension edge 30 of the right outer frame member 22c and the front base wall 2 are prevented.
4 and a recess 37 surrounded by the step 25
Are formed. Therefore, when the inner frame member 51 is opened and closed, the outer projecting edge 59 of the right inner frame member 52c is connected to the right outer frame member 2.
The problem of collision with and damage to the lining projection 30 and the front base wall 24 of the 2c is eliminated.
