A very strong framework is obtained by the connection structure of the connection villages 18a, 18b, 18c, 18d and the connection holes 15a, 15b, 15c, 15d that cross each other.

In particular, the side village portions 12b, 12c, 13b of the bottom punches 12, 13
, 13c and the linking punches 18a, 18b, 18c, 18d remain almost parallel both in the open state and during the folding operation, making the frame of the bed very strong. In addition, when folding this bed, it is only necessary to rotate the tips of the first and third upper branches 4a and 4c upward to bring the front frame 1 and the rear frame 2 closer to each other. , 2, the bed is folded by moving in parallel, so there is no jerky feeling and the folding operation is very smooth and easy. FIG. 4 shows the structure of a locking device for a baby bed according to another embodiment of the present invention, in which 4a, 4b,
Reference numeral 6a indicates the same bracket as in the above embodiment, and 5c indicates a bracket 43 that is slightly different from the bracket 5a in the above embodiment.
The second upper branch 4b is rotatably connected to this bracket 5c by a pin 27.

In addition, 28 is the pond edge of the first upper supporting punch 4a and the second upper supporting punch 4b.
A locking body is inserted into both of the other ends to hold both the upper support punches 43, 4b in a straight line, and this locking body 28 is connected to the fixing pin 26. The spring 29 inserted between the left end of the hook body 28 in FIG.
It is urged in the direction of the upper branch village 4b. Further, 30 is a U-shaped lock lever that is rotatably attached to the grip 6b with pins 31a and 31b, and a wire locking lever is provided at a location slightly apart from the pins 31a and 31b of this lock lever 30. The wire 3 is inserted between the lock body 30a and the lock body 28 through a through hole 40 provided in the first upper punch 4a.

, can be attached to the third upper support 4a, 4c,
It may be attached to only one side.

Note that when this locking device is installed, the locking knobs 20a and 20b shown in FIG. 1 are not necessary. Next, a method of operating the rock diamond layer of this embodiment will be explained.

In the open state of the bed corresponding to Fig. 1, the lock body 2
8 and the lock lever 30 are in the state shown in FIG. The upper punches 4a and 4b are held in a straight line.

Therefore, even if some external force is applied to the bed, both Kamishibura 4a
, 4b remain straight and the bed is not folded. To fold the bed from this state, hold the grips 6a and 6b with both hands.

When the lever 30 is rotated in the direction of arrow A, the wire 32
is pulled to the left in the figure, and the lock body 28 moves to the left in the figure while compressing the spring 29. and lock lever 30
When the wire 32 is laid out to the position shown in FIG. Since it is pulled to the right, the lock lever 30 is locked in this state. In this state, the lock body 28 is completely removed from the second upper branch 4b, so the second upper branch 4b and the first upper branch 4a can be folded into a V-shape, and the following steps are as described above. The bed can be folded like this. In this embodiment, since the lock lever 30 is attached to the grip 6a, the unlocking operation and the folding operation can be performed with a single touch, making the operation extremely easy.

FIG. 5 shows a lock lozenge according to still another embodiment of the present invention, in which turtles a and 4b' are the same first and second upper punches as in the first embodiment, and 33 is the same as the first embodiment. Both upper supports 4a,
4b are rotatably connected in a linear and lockable manner.

The connecting punch 33' is made up of a disc-shaped bottom 3, a cylindrical lid 35, and a knob 38 fixed to the lid 35. Three characters?
3. It is mounted so that it can rotate freely. Also, on the left and right sides of the cylindrical cover gun flea, there are three cutouts into which the above-mentioned Kamishimura &a and filler are inserted. 39b is formed, and a cylindrical spring housing portion 48 is formed in the center thereof.
A pin 1 fixed to the bottom plate 341 is inserted through the center of the spring accommodating portion 48. A spring 42 is inserted between the bottom surface 40a and the bottom surface 40a.In this embodiment as well, the locking device is
, 4d, but it may also be attached to only one of the first, second, or third L and fourth upper punches.

Next, the operating method of this embodiment will be explained.

FIG. 5 shows the locked state of this locking device. In this state, the lid 35 is urged upward in FIG.
, 39b and the bottom plate 34 to form a straight line.
In this state, both upper branches 4a, 4b cannot rotate relative to each other, and the bed is thus locked in the open state. To fold the crib from this open position,
If you hold the knob 36 in your hand and pull it toward you by a distance equal to or greater than the thickness of both upper punches 4a and 4b, against the force of the spring &2,
The upper support punches 4a, 4b are disengaged from the notches 39a, 39b, and the upper support punches 4a, 4b can freely rotate relative to the bottom plate 34. Therefore, if the locking device 33 is pushed down while pulling the knob 36 toward you in this way, both upper branches 4a and 4b will form a V-shape downward, and the crib can be folded in the same manner as above. . In this embodiment, the operation of unlocking the locking device and the operation of folding the bed can be performed successively by holding the knob, so the operation is very easy.

Moreover, unlike the first and second embodiments, it is not necessary to make one ends of the first and third upper supports 4a, 4c protrude outward from the front frame 1, so there is no protrusion, making it safe and aesthetically pleasing. The upper part is also preferable.In the first embodiment, rotating parts are attached to the side parts of the front and rear frames so that the upper part of the ichiyanagi side can be rotated outward and downward so that infants can be taken in and out easily. However, “
This round punch may be omitted; in this case, the first and second upper branches are directly attached to the side punch portions of the front and rear frames. In the claims of the present application, the device that does not have this rotation is defined as the first invention, and the device that has a turning point is defined as the second invention. Further, in the first embodiment, the rotating arm 23,
A first operating punch 24 and a second operating lever 25 are provided, and by gripping the grips a and 6b and rotating them upward, the user can step on the center section 122 of the bottom part 12 to make it easier to fold. However, this spreading arm 23 and the first and second operating elements 24 and 2 do not need to be installed.Furthermore, in the above embodiment, the side village portion and the upper village portion are integrally formed in an inverted U shape. Although the front and rear frames are used, the side village part and the upper village part may be separate bodies, or a lower village part may be further provided between the lower ends of the side punch.

In addition, in the above embodiment, even if the upper ends of the side punches of the front and rear frames are connected by the upper branch, the upper ends of the side punches of the rear frame are connected between the front ends or the rear ends of the upper branch punch. They may be connected by a U-shaped frame having a central village part.Also, in the above embodiment, a U-shaped bottom village in which the side punch part and the central punch part are integrally formed is used. The side punch portion and the central village portion may be separate bodies. One end is attached to the side punches of the front and rear frames, and the other end is attached to the bracket at the edge of the pond at the bottom of the bottom village, so the frame of the crib is very strong. When folding, the upper branch is folded into a V-shape and the front and rear frames are moved in parallel, thereby making it possible to perform the folding operation very smoothly and easily.
