Description

  The present invention relates to a building basic inspection port.

  In recent years, for example, efforts have been made to save energy by using a space below a bathroom using a unit bath as an airtight and heat insulating structure. Specifically, the airtightness and the heat insulation are improved by blocking the ventilation into the lower space of the bathroom surrounded by the concrete cloth foundation and spreading the heat insulating material on the inner wall of the cloth foundation. At this time, it is necessary to provide a through hole or an inspection port (basic inspection port) for checking the floor under the cloth foundation.

  The applicant of the present invention can adopt a frame body fixed to the fabric foundation, a lid made of foamed resin having heat insulation, and a lock for pressing the lid body to the frame body, which can be adopted for such a basic inspection port. A basic inspection port having a mechanism is proposed (see Patent Document 1). In this basic inspection port, the lock body is released and the lid body is pulled forward, so that the lid body can be removed from the frame body, and when the lid body is fitted to the frame body and locked again, the original state is restored. That is, the basic inspection port can be easily opened and closed any number of times, and the bathroom section can be easily inspected.

  The lock mechanism in the basic inspection port described in Patent Document 1 is configured by a slide-type lock that is slidable left and right by a lock pressing plate that is bonded to the left end portion of the lid with an adhesive or the like. Since the lock pressing plate is bonded to the surface side of the relatively brittle foamed resin lid, there is a possibility that the slide-type lock may fall off by repeatedly using the slide-type lock, and the slide-type lock may also fall off from the lid.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a basic inspection port that can reduce the dropping of the locking member from the lid even if the lid is made of a relatively fragile material.

  The basic inspection port of the present invention has a frame portion having an opening portion, a frame body having a locked portion provided on an inner peripheral edge portion of the frame portion, and a heat insulating property that can be fitted into the opening portion. A lid, and a lid having a locking member that can be locked to the locked portion in a state in which the lid is fitted to the opening, and the locking member includes the lid Are attached so as to be sandwiched from the front-rear direction parallel to the thickness direction.

  According to this, since the locking member is attached to the lid so as to be sandwiched from the front-rear direction parallel to the thickness direction, even if the lid is made of a relatively fragile material such as foamed resin, It becomes possible to reduce that a member falls off from a cover part.

  In the present invention, it is preferable that the locked portion is constituted by a locked member attached so as to sandwich the frame portion from the front-rear direction. Thereby, since the to-be-latched member which comprises a to-be-latched part is attached to a frame part so that it may clamp from the front-back direction, even if a frame part is comprised from comparatively brittle materials, such as foamed resin, It becomes possible to reduce that the to-be-latched member falls off from the frame portion.

  In the present invention, the locking member includes a front portion, a rear portion, and a side portion that connects the front portion and the rear portion, and a sandwiching portion that sandwiches an outer peripheral end portion of the lid portion. An operation portion that is integrally formed with the clamping portion and is movable in the left-right direction orthogonal to the front-rear direction by elastic deformation, and the lid is fitted into the opening portion in the operation portion It is preferable that a protrusion that is locked to the locked portion is formed by moving the operation portion in the left-right direction by elastic deformation when the operation portion is moved. Thus, the lid can be easily locked, that is, locked to the frame simply by fitting the lid to the opening. In addition, the manufacturing cost is lower than that in which the locking member is composed of a combination of a plurality of separate members.

  In the present invention, it is preferable that at least one of the front part and the rear part is formed with a protrusion for restricting movement of the clamping part in the left-right direction with respect to the lid part. Thereby, when the operation unit moves in the left-right direction, the clamping unit becomes difficult to move in the left-right direction. For this reason, the lid can be effectively locked to the frame.

  In the present invention, the locking member has a front part, a rear part, and a side part connecting the front part and the rear part, and the front part is connected to the locked part. It is preferable that the stopper can be moved by elastic deformation so that the stopper can be unlocked. As a result, the cover body can be locked to the frame body by using the elastic deformation of the locking member, so that no special separate member is required for locking, and the lid body can be locked and unlocked by a simple operation. It can be carried out.

  According to the basic inspection port of the present invention, since the locking member is attached to the lid so as to be sandwiched from the front-rear direction parallel to the thickness direction, the lid is made of a relatively fragile material such as foamed resin. However, it is possible to reduce the dropping of the locking member from the lid.

The rear portion 53 has a long rectangular shape in the vertical direction C when viewed from the rear, and is integrally connected to the rear end of the side portion 52. A protrusion 53 a that protrudes forward is formed at the tip (right end) of the rear portion 53. The protrusion 53 a is formed in a shape that can be fitted into the groove 26.

  The operation part 42 is arranged at a position sandwiching the side part 52 in the vertical direction C and connects the first part 43 and the rear part of the side part 52 when viewed from the front. A pair of second portions 44. The first portion 43 is made of a plate-like member in which a circular hole 43a penetrating in the front-rear direction B is formed. The second portion 44 is formed of a plate-like member that extends leftward from the left end portion of the first portion 43 and then bends backward along the shape of the stepped portion 30. Further, a locking projection 46 is formed on the pair of second portions 44. The locking projection 46 has a front inclined portion 46a that is inclined so as to be separated from the second portion 44 as it goes rearward, and a rear inclined portion 46b that is inclined so as to be separated from the second portion 44 as it goes forward. doing.

  Such a locking member 23 is attached to the recess 22a1 so that the projection 51a is fitted in the groove 25 and the projection 53a is fitted in the groove 26. Thereby, the locking member 23 is attached so that the left end portion of the lid portion 22 is sandwiched in the front-rear direction B by the sandwiching portion 41 as shown in FIG. As shown in FIG. 10, the operation unit 42 is separated from the clamping unit 41 through a slit 45 except for a connection portion with the side part 52. Accordingly, the first portion 43 of the operation portion 42 of the locking member 23 attached to the lid portion 22 can be moved in the left-right direction A by the elastic deformation of the second portion 44. Therefore, when the user puts a finger into the circular hole 43a and the recess 22a2 of the first portion 43 and moves the first portion 43 in a direction approaching the recess 22a2, the second portion 44 is elastically deformed and the first portion 43 is moved. Approaches the recess 22a2. That is, the first portion 43 moves to the right. At this time, since the front portion of the second portion 44 also moves to the right, the locking projection 46 inserted into the groove 11c and locked to the locked member 13 is released from the groove 11c, and the locking is released. The Thus, the lid 21 can be removed from the frame 11 forward when the locking projection 46 and the locked member 13 are unlocked.

  In addition, the frame 11 in this embodiment is formed in line symmetry with respect to a center line parallel to the vertical direction C passing through the center in the left-right direction A. For this reason, the lid 21 can be attached to the frame 11 regardless of whether the locking member 23 is on the left or right.

  As described above, according to the basic inspection port 10 of the present embodiment, since the locking member 23 is attached to the lid portion 22 so as to be sandwiched from the front-rear direction B, the lid portion 22 is a relatively brittle material. Even if it is made of (foamed resin), it is possible to reduce the dropping of the locking member 23 from the lid portion 22.

  Further, the locked member 13 is attached so as to sandwich the frame portion 12 from the front-rear direction B. Thereby, even if the frame part 12 is comprised from a comparatively brittle material (foamed resin), it becomes possible to reduce that the to-be-latched member 13 falls from the frame part 12. FIG.

  Further, the protrusion 51 a is formed on the front portion 51 of the sandwiching portion 41 and the protrusion 53 a is formed on the rear portion 53, so that the sandwiching portion 41 is restricted from moving in the left-right direction A with respect to the lid portion 22. . Thereby, when the operation part 42 moves in the left-right direction A, the clamping part 41 becomes difficult to move in the left-right direction A. For this reason, the lid 21 can be effectively locked to the frame 11.

  The preferred embodiments of the present invention have been described above. However, the present invention is not limited to the above-described embodiments, and various modifications can be made as long as they are described in the claims. For example, in the above-described embodiment, the locking member 23 is disposed in one of the left and right directions A of the lid portion 22, but may be disposed in one of the vertical directions C. In this case, the locked portion (locked member) may also be disposed on one side in the vertical direction C of the frame portion 12 so as to correspond to the locking member. Also in this case, the same effect as described above can be obtained.

  Moreover, although the to-be-latched member 13 in the above-mentioned embodiment is attached so that the frame part 12 may be clamped from the front-back direction B, you may form integrally with the frame part 12. FIG. In this case, a groove or a recess (locked portion) that can be locked with the locking protrusion 46 of the locking member 23 may be provided on the inner peripheral edge of the frame portion.

  Further, only one of the protrusion 51a and the protrusion 53a formed on the locking member 23 may be formed, or both of them may not be formed.
