Description

  The present invention relates to a handle attachment structure for an underfloor inspection port.

  As a conventional handle attachment portion structure in the seed floor inspection port, for example, as disclosed in Patent Document 1, a handle is constituted by a main body portion and a handle member, and the handle member is a horizontal shaft in the main body portion. It is provided in a pivotal manner, and this handle member is configured to be able to protrude from a long hole formed in the upper plate portion of the main body portion by rotating around the shaft, and the upper plate portion is a side plate parallel to each other of the main body portion. The upper end of the part is connected so as to protrude from the outer surface of the side plate part and both front and rear end faces, and the outer plate of the side plate part is provided with a spring locking piece so as to protrude from both sides of the main body part at a plurality of positions. This spring locking piece protrudes below the upper plate part protruding from the outer surface of the side plate part with an extension length shorter than the extension length of the upper plate part, and the spring locking piece of each step on the outer surface of both side plate parts is paired. In the notch hole formed in the lid of the underfloor inspection port In the state where the lower side of the upper plate part of the hand is fitted, a pair of spring locking pieces at appropriate height positions on the outer surface of the side plate part projecting downward from the notch hole part on the back side of the cover plate A structure in which a leaf spring is inserted and locked from both ends in the length direction is known.

  A long hole is formed in the upper end of the main body part used in the handle attachment part structure of Patent Document 1 above, and openings are formed between both end portions of the side plate parts parallel to each other. There is a problem in that air flows between the floor and the room, which affects the temperature control effect in the room during air conditioning.

  The object of the present invention is to solve such a problem, and in the attachment portion of the handle to the lid of the underfloor inspection port, the room above the lid and the floor below the lid are completely blocked, An object of the present invention is to provide a handle attachment structure for an underfloor inspection port in which air does not flow between the underfloor.

  The handle attachment structure of the underfloor inspection port according to claim 1 of the present invention is a handle attachment portion structure in which a handle attachment body is fitted from above into an opening formed in a lid that closes the underfloor inspection port. A cap made of a synthetic resin covering the opening from the back side of the lid, and a packing material is provided in the groove of the protruding portion at the upper end of the cap, and the cap is screwed to the handle attachment body to form the packing. The material is configured to be pressed against the back surface of the lid.

  As described above, the handle attachment portion structure of the underfloor inspection port according to the present invention is configured such that the packing material provided at the upper end of the cap is pressed against the back surface of the lid body in the attachment portion of the handle to the lid body of the underfloor inspection port. Therefore, it is possible to provide a handle attachment structure for an underfloor inspection port that completely shuts off the room above the lid and the floor below the lid and prevents air from flowing between the room and the floor. .

It is a perspective view which shows the rotary handle used for the handle attachment part structure of the underfloor inspection port in one embodiment of this invention. It is a front view of the same rotary handle. It is sectional drawing of the rotation handle. It is a perspective view of the cap used for the handle attachment part structure of the same floor under inspection port. It is a front view of the cap. It is a side view of the cap. It is a top view of the cap. It is a bottom view of the cap. It is sectional drawing of the same cap. It is a top view of the handle attachment part with respect to the cover body. It is sectional drawing of the handle attachment part with respect to the cover body. It is a partially broken expanded sectional view of the handle attachment part to the lid.

Hereinafter, an embodiment of the present invention will be specifically described with reference to FIGS.
In the figure, reference numeral 1 denotes a rotary handle provided in a lid body 4 that closes an underfloor inspection port 3 formed in a floor material 2, which fits into an opening 5 formed in the lid body 4, and the back surface of a surrounding collar portion 6 is It fits in the hole 8 of the handle attachment body 7 which contacts the upper surface of the lid 4 around the opening 5 and is attached to the handle attachment body 7 so as to be rotatable around the horizontal axis 9.

  In this rotary handle 1, when the lid 4 is closed, the upper surface of the horizontal portion 1 a is flush with the upper surface of the handle attachment body 7, and the circular portion 1 b at one end of the horizontal portion 1 a is pushed down with a finger. Accordingly, the grip 1c formed on the lower side of the horizontal portion 1a is configured to protrude upward from the hole 8 and rise up. Then, when the hand is released from the grip portion 1c, the rotary handle 1 is rotated to the original state so that the upper surface of the horizontal portion 1a is flush with the upper surface of the handle attachment body 7. The rotary handle 1 and the handle attachment body 7 are both made of metal, and female screw holes 10 and 10 are formed on the back surfaces of both ends of the handle attachment body 7.

  The handle attachment body 7 including the rotary handle 1 is fitted into the opening 5 so as to close the opening 5 formed in the lid 4 as described above. In this state, the grip portion 1 c of the rotary handle 1 protrudes downward from the back surface of the lid 4. In this state, the opening 5 is covered with the synthetic resin cap 11 including the rotary handle 1 and the handle attachment body 7 from the back surface side of the lid 4. Specifically, the cap 11 includes a bag-like recess 12 that protrudes downward so as to rotatably accommodate the grip portion 1c of the rotary handle 1, and the upper end connected to the recess 12 projects outward over the entire circumference. An overhanging portion 13 is provided, and a concave groove 13a is formed on the entire upper surface of the overhanging portion 13, and a sealing packing material 14 slightly extends upward from the groove 13a in the groove 13a. It is fitted to protrude. Reference numeral 15 denotes a screw insertion hole formed so as to be opposed to the female screw hole 10 of the handle attachment body 7 inside the groove 13a formation portion at both end positions of the projecting portion 13.

  In the above configuration, when the rotary handle 1 is attached to the lid body 4, the handle attachment body 7 is set so that the back surface of the surrounding flange portion 6 abuts the upper surface of the lid body 4 around the opening portion 5. The cap 11 is applied from the back surface side of the body 4 so that the upper end of the overhanging portion 13 abuts the back surface of the lid body 4 around the opening 5, and in this state, the screw insertion hole 15 from the back surface side of the lid body 4. By attaching the screw 16 inserted into the female screw hole 10 of the handle attachment body 7, the attachment of the rotary handle 1 to the lid body 4 is completed. In the attachment portion of the rotary handle 1 attached in this way, the cap 11 including the rotary handle 1 and the handle attachment body 7 and covering the opening 5 is covered with the packing material 14 provided in the groove 13a of the protruding portion 13 at the upper end. By press-contacting the back surface of the body 4, the room above the lid body 4 and the floor below the lid body 4 are completely blocked, and air does not flow between the room and the floor.

  The handle attachment structure of the underfloor inspection port according to the present invention completely shuts off the room above the lid of the underfloor inspection port and the floor below the lid, so that no air flows between the room and the underfloor. It is a handle attachment part structure of a mouth.
