Numeral 65 is a joint shaft made of a metal rod, which is longer than the length of the collar 62 and whose outer diameter is
Are formed substantially equal to the inner diameter of the through hole 63, and a ring groove 66 is provided on one side in a biased manner. Reference numeral 67 denotes an E-ring that is mounted in the ring groove 66.

In the mounting mechanism 7, reference numeral 71 denotes an adjusting screw, which includes a disk-shaped head 72 made of, for example, a synthetic resin, and a screw rod 73 which is inserted into the head 72 via a detent means and integrated therewith. And the screw rod 73 is a collar 62
Has an outer diameter that allows it to be slidably inserted into the through hole 63. Numeral 75 designates an adjusting handle made of synthetic resin and having a substantially disk shape and having, for example, uneven anti-slip on the outer periphery thereof, and a screw hole 73 of an adjusting screw 71 screwed into a through hole 76 provided at the center. Are inserted and integrally formed, and one surface is provided with a concave portion 78 into which the head 72 of the adjusting screw 71 is fitted.

Next, the procedure for assembling the joint mechanism 6 composed of the above components will be described. First, color 6
2a provided in the frame cover 28a of the support frame 21
0a is fitted into the hole 26a provided in the vertical frame 23a of the frame 23, and the flange 64 is brought into contact with the side surface of the frame cover 28a. The metal pipe 61 is inserted into the hole 31 provided in the adjustment panel 3a, and the collars 62b and 62c are fitted into both ends of the metal pipe 61, respectively.

The supporting panel 22a of the support frame 21 has an adjusting panel 3a
When connecting the E-ring 67 of the joyton shaft 65, the longer one from the ring groove 66 into which the E-ring 67 is mounted
And the E-ring 67 is brought into contact with the flange 64 of the collar 62a. When the collar 62b provided on the adjustment panel 3a is inserted into the other end of the joint shaft 65, the support frame 21 and the adjustment panel 3a are integrally connected.

Further, the screw rod 73 of the adjustment screw 71 is screwed into the nut 77 provided on the adjustment handle 75 of the fixing mechanism 7 until the head 72 of the screw rod 73 is located in the recess 78 of the adjustment handle 75.

Next, an example of a procedure for mounting the above-configured infant gate G between the opposing walls will be described. (1) The adjustment panels 3a, 3b are connected to both the columns 22a, 22b of the support frame 21 by the joint mechanism 6, and the adjustment handle 75 is screwed into the through hole 63 of the collar 62c from outside the adjustment panels 3a, 3b. The screw rod 73 of the adjusted screw 71 is inserted.

(2) The support frame 21 and the adjustment panels 3a and 3b integrated with the support frame 21 are disposed at predetermined positions between the opposing walls. (3) In this state, the adjusting handle 75 of each mounting mechanism 7 is rotated to move the adjusting screw 71 in a direction away from the adjusting panels 3a and 3b, and the heads 72 are pressed against the opposing walls. Thus, the adjustment panels 3a and 3b are also pressed against the columns 22a and 22b of the support frame 21, and the adjustment panel 3
a, 3b and the support frame 21
Along with the reaction force of the a and 23b, it is firmly installed between the opposing walls.

(4) The door body 11 is inclinedly inserted between the opposing columns 22a and 22b, and the bearing 1 provided on the upper part thereof is provided.
3a is connected to the frame cover 28 of the support 22a of the support frame 21.
Then, the door 13 is fitted to the support shaft 29a provided at the upper part of a, and the bearing 13b provided at the lower part is fitted to the support shaft 29b to lower the door body 11. At this time, when the tip of the lock bar 58 interferes with the lower frame 24 of the support frame 21, the lock of the lock mechanism 4 may be temporarily released and the lock bar 58 may be pulled up. Note that a spacer may be fitted to the support shaft 29b. Thus, the door body 11 is supported by the support frame 21 so as to be openable and closable.

(5) Next, the door body 11 is fixed to the support frame 21.
When the lock handle 41 is pressed down and lowered, the locking claw 53 is locked to the locking portion 17 and the lower opening of the lock handle 41 is provided on the frame cover 28b of the support 22b. The lock bar 58 is inserted into the lock hole 25 (or cap 32) provided in the lower frame 24 of the support frame 21, and the door body 11 is securely locked.

The distance between the opposing walls such as passages is not always constant, and may be wide or narrow. In the above example, the case where the distance between the opposing walls is wide has been described. However, the present invention can also cope with the case where the distance between the opposing walls is narrow as follows. That is, as shown in FIG. 11, the adjustment panel 3 is connected to one side of the support (for example, 22a).
And the other side is provided with a support frame 2 as shown in FIG.
The joint shaft 65 is not inserted into the collar 62 mounted on the first support 22b, and the screw rod 73 of the adjustment screw 71 screwed into the adjustment handle 75 of the mounting mechanism 7 is directly inserted into the through hole of the collar 62. Things.

As described above, the adjustment panel 3 is provided only on one side of the door 1, and the adjustment panel 3 is omitted on the other side.
The screw rod 73 of the mounting mechanism 7 is directly inserted into one of the columns (for example, 22b) of the support frame 21, and the head 7 of each adjusting screw 71 is inserted.
If the 2 is pressed against the opposing wall, the width of the infant gate G can be narrowed by the width of the adjustment panel 3, so that it can be easily installed even between the narrow opposing walls.

Further, when the distance between the opposing walls is small, the adjustment panels 3 on both sides of the door 1 are omitted, and the support columns 2 of the support frame 21 are omitted.
If the mounting mechanism 7 is directly mounted on the 2a, 22b, the width of the infant gate G can be reduced by twice the width of the adjustment panel 3, so that it can be easily provided between narrower opposing walls. Can be installed in

As described above, according to the present invention, the width of the infant gate G is adjusted in three steps, and the width can be finely adjusted by the adjusting screw 71 of the mounting mechanism 7. It can be easily and widely installed between walls, and the degree of freedom of installation can be greatly expanded.

Although the embodiment of the present invention has been described above, the present invention is not limited to this, and can be appropriately changed without departing from the gist of the present invention.
