This relates to a protective frame for infants that prevents

[Conventional technology]

As a conventional technology for a protective frame for infants that partitions doorways, entrances and exits of stairs, etc., there is
There are some published in the official gazette.

The above-mentioned infant protection frame has a pillar material provided on one side of a pair of left and right side frames attached to a wall or pillar, etc., and when the operating member is rotated in the direction of falling down, the remaining side By extruding the frame and pressing the vertical surface of the extruded side frame against a wall or pillar, rotation in the opening direction is stopped and the frame is held in a fixed position.

In addition, the operation member is rotated in the rising direction and the remaining side frame is pulled against one side frame to release the above-mentioned pressing, so that the infant protection frame can be rotated in the opening direction and moved in and out. ing.

[The problem that the idea aims to solve]

Since the side frame is pressed and released by sliding the side frame by operating the operating member, there is a problem in that the operating member must be operated each time before and after passing.

In addition, the up-and-down rotation of the operating member is converted into a sliding movement of the side frame via the link, and the engagement between the hook and the pin prevents the tilted operating member from rotating in the up-and-down direction, resulting in a complicated structure. There was a problem that caused the cost to rise.

[Means to solve the problem]

In order to solve the above-mentioned problems, this device is designed to rotatably attach the end side of the protective frame to one side of the opposite side of the passage, and to maintain the closed state when the protective frame crosses the passage. In the protective frame, a latch bolt that can freely come out and retract and is given protrusion is provided on the front end surface of the protective frame, and the latch bolt is recessed into the other side of the opposite side of the passage just before the protective frame is closed, and A receiver that engages with the latch bolt at the end of closing is provided so as to be movable up and down, and a force is applied to the receiver to return it to the position where it engages with the latch bolt, and the engagement relationship between the latch bolt and the receiver is released. In addition, the protection frame is provided with a sliding operation member and is provided with the ability to rotate in the closing direction.

[Effect]

When opening the protective frame, the receiver is pulled up by the operating member to release the engagement between the receiver and the latch bolt.

Then, open the protective frame while pushing the tip side (free end side).

In addition, when the protection frame starts to open, the raising of the receiver is canceled.

When you release your hand from the open protection frame after passing the above,
Automatically close the protection frame.

Just before the protection frame is closed, the latch bolt is retracted by the receiver, and when the protection frame is finished closing, the latch bolt is automatically engaged with the receiver to maintain the closed state of the protection frame.

〔Example〕

As shown in the figure, a protective frame 1 is installed at a passageway such as a doorway or an entrance or exit of stairs, which is closed across the passageway and opened by rotating in one direction on the opposite side of the passageway.
The protective frame 1 is provided with the ability to rotate in the closing direction.

The above protective frame 1 has two rods 2 and 2 on both sides as shown in the figure.
The upper and lower ends of the rods 2, 2 and the middle of the upper and lower ends are connected to each other and protrude inwardly from each other,
Connecting rods 3, 3 whose opposite ends are slidably fitted
A bolt 4 is screwed into the outer connecting rod 3 and fixes the inner connecting rod 3 to the outer connecting rod 3, and the upper and lower connecting rods 3 are supported by fitting the bag portions on the upper and lower edges. Although the space between the rods 2, 2 on both sides can be freely adjusted depending on the width of the passage, other structures may be used.

In addition, the method of attaching the protective frame 1 is as follows: In the case shown in the figure, two pillars 6, 6 made of pipe are brought into contact with the passage surface, and the pillars 6, 6 are connected from the upper and lower ends of the pillars 6, 6 and protrude inwardly from each other. At the same time, when the support rods 7, 7 whose opposite ends are slidably fitted and the operating member 8 rotatably attached to one support rod 7 are rotated parallel to the support rod 7, the other side is rotated. The support rods 7, 7 are pushed out in opposite directions through a link 9 whose both ends are rotatably connected to the support rod 7 and the operating member 8, and the pillars 6, 6 are placed on opposite sides of the passage. A frame body 10 is provided to press and support the protection frame 1, and at least two upper and lower U-shaped holding fittings 11 attached to one of the supports 6 are passed through the side rods 2 on the distal side of the protective frame 1 so that the protection frame 1 can be opened and closed freely. Although the protective frame is attached, the end edge of the protective frame may be attached to a pillar or wall of the passageway via a hinge or the like.

Furthermore, the rotatability in the closing direction given to the protection frame 1 is as follows:
In the case shown in the figure, a coil spring 12 is installed in the side rod 2 made of pipe, and the coil spring 12 is engaged with both ends of the coil spring 12 and incorporated into the side rod 2 on one side, and one side is fixed to the side rod 2 with screws, welding, etc. The fixed receiving seat 13 and the other upper part are attached to the pipe side rod 2.
A receiving seat 14 rotatably fitted to the lower end of the seat 14 and a screw 15 fixing this lower receiving seat 14 to the pillar material 6.
When the protective frame 1 is opened, the coil spring 12 is wound around the coil spring 12, but the coil spring 12 may be applied by other methods.

Further, a latch bolt 17 is provided on the front end surface of the protective frame 1, and is capable of coming out and retracting freely and is provided with a protruding property.

In the illustrated case, the latch bolt 17 is inserted into a rectangular through-hole 18 provided on the front end surface of the protective frame 1, and is pushed back by a spring 19.

Further, on the other side of the opposite surface of the passage, a receiver 20 is provided which is movable up and down, into which the latch bolt 17 is inserted just before the protection frame 1 is closed, and into which the latch bolt 17 is fitted and engaged when the protection frame 1 is closed. There is.

Further, when the operating member 21 is operated, the receiver 20 slides to a position where the engagement relationship between the latch bolt 17 and the receiver 20 is released, and the operating member 21
When the operation is released, the latch bolt 17 and receiver 20
and are automatically returned to the position where they are in an engaged relationship.

With the above configuration, when opening the protective frame 1, operating the operating member 21 and sliding the receiver 20 upward in the figure will remove the receiver 20 from the latch bolt 17, so push or pull the protective frame 1. Can be opened.

The operation of the operating member 21 is released when the protective frame 1 is opened, and the receiver 20 is pushed back to the regular position as the protective frame 1 is released. Therefore, when the protective frame 1 is closed, the latch bolt 17 comes into contact with the receiver 20 just before the closing is completed. The latch bolt 17 is retracted and passes through, and the latch bolt 17 that projects when the protective frame 1 is closed is caught by the receiver 20 or the closed state of the protective frame 1 is maintained.

In the illustrated case, the above-mentioned receiver 20 uses a planar U-shaped bent plate, and is fitted on the outside of the pillar 6, and
Two pins 22, upper and lower, whose ends are supported on the upper and lower sides of the opposing sides of the receiver 20, are passed through the longitudinal long holes 23 provided in the column 6, and a cylindrical manipulator is installed on the outside of the column 6. A pin 24 into which the member 21 is slidably fitted and whose both ends are supported by the operating member 21 is inserted into a longitudinally elongated hole 25 provided in the pillar member 6.
through the pins 24 and 22, and connect the connecting plate 26 to the pins 24 and 22.
Both ends of the pin 24 are fixed, and a spring 27 for pushing down the pin 24 is incorporated into the column 6, so that when the operating member 21 is not normally operated, the receiver 20 is pushed back to the normal position.

In the figure, reference numeral 16 denotes rubber pieces that are provided at the upper and lower ends of the pillar material 6 and pressed against the opposing surface.

〔effect〕

As described above, according to the infant protection frame of this invention, when the receiver is slid by operating the operating member, the engagement between the receiver and the latch bolt is released, so the protection frame is rotated and opened. can do.

Also, when the operation of the operating member is released, the receiver returns to its original position, and the protective frame is rotated in the closing direction due to the rotatability provided, and the latch bolt automatically engages with the receiver, and the protective frame is closed. This prevents children from pushing open the protective frame and running outside or falling down the stairs.
