Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a baby bed for laying an infant.
[0002]
[Prior art and problems to be solved by the invention]
In general, in a baby bed where an infant is laid down, a vertical lattice-shaped side frame having a predetermined height is provided around the circumference of the baby bed to prevent the infant from falling down due to turning over. However, if all of the side frames are fixed, the mother or the like needs to bend his / her waist greatly when the baby is put in and out of the baby bed or when the diaper is changed.
[0003]
Therefore, in particular, the front side frame on the side where the baby is put in and out is a front opening type or a descending slide type, usually the front side frame is held in the closed position, and when the baby is put in and out, the front side frame is opened, There are things that make workability better.
[0004]
Such a front side frame is normally configured so that both sides thereof are fixedly held by latches to the left and right corner columns.
[0005]
However, in the case where the front side frame can be opened and closed in this way, when the baby is standing and playing with a bed, the front side frame will be opened if the baby unlatches for some reason. In addition, there are problems such as the possibility that an infant may fall from the bed.
[0006]
In view of these points, the present invention provides a baby bed that prevents the front side frame from opening naturally even when the latch that holds the front side frame in the normally closed position is released. The purpose is to obtain.
[0007]
[Means for Solving the Problems]
The present invention, in a baby bed having a side frame on the outer peripheral portion, constitutes an open / close door by mounting the front side frame on the long side so as to be vertically slidable with respect to the left and right corner columns, and constitutes the open / close door A first locking device is provided on both sides of the front side frame to engage with the left and right corner posts to hold the front side frame in the closed position, and the front side frame or the left and right corner posts A second locking device for preventing the front side frame from descending at the closed position is provided on the upper horizontal rail connecting the intermediate portions.
[0008]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
[0009]
FIG. 1 is a perspective view of a baby bed according to the present invention, which is rectangular in plan view, and corner posts 1a, 1b, 1c, 1d are arranged at corners of the rectangle. A vertical grid-like side frame is provided between the columns.
[0010]
That is, the lower left and right corner support pillars 1a and 1b are connected to each other at the bottom by the lower crosspiece 2, and the rear side frame 3 on the long side is disposed in the upper half between the corner support pillars 1a and 1b. The left and right corner columns 1a, 1b are integrally connected by the rear side frame 3. The front and right corner struts 1c and 1d are connected to each other at the middle and lowermost portions by an upper horizontal rail 4 and a lower horizontal rail 5. Further, between the corner struts 1b and 1c and between the corner struts 1d and 1a, side frames 6 and 7 on the short side are respectively disposed in the upper half portions. 1c and corner posts 1d and 1a are connected.
[0011]
On the other hand, a front side frame 8 on the long side is disposed between the left and right corner columns 1c, 1d at the front. Engagement pieces (not shown) project from both side portions of the front side frame 8, and the engagement pieces slide in longitudinally extending grooves 9 provided on the opposing surfaces of the left and right corner columns 1c and 1d. The front side frame 8 is slidably movable along the left and right corner columns 1c and 1d. That is, an openable / closable door is configured by the front frame 8.
[0012]
The left and right vertical frame members 8a and 8b of the front side frame 8 are provided with slide slides 10 that are biased so as to protrude from the inside to the outside by springs (not shown). When the front side frame 8 is in the upper closed position, the front end of the slide latch 10 is inserted into a locking hole (not shown) provided on the opposing surfaces of the left and right corner columns 1c, 1d. The front side frame 8 is held in its closed position.
[0013]
Then, the front latch 8 is moved downward by operating the slide latch 10 and pulling out the tip of the slide latch 10 from the engaging holes of the corner struts 1c and 1d, and the front frame 8 is opened as shown in FIG. Can be placed in a state. In the figure, reference numeral 11 denotes a mat laid on the floor board, and 12 denotes casters provided on the lower horizontal rails 2 and 5.
[0014]
Incidentally, the upper horizontal rail 4 is provided with a second lock device 13 for preventing the front side frame 8 from being lowered at the closed position (upper position). FIG. 3 is an enlarged perspective view of the locking device 13, and a notch groove 14 extending in a direction perpendicular to the axis of the upper horizontal beam 4 is formed at a substantially central position of the upper horizontal beam 4. A notch recess 15 wider than the width of the notch groove 14 is formed in the front part of the notch groove 14. And the guide groove 16 extended in a horizontal direction is provided in the left-right opposing surface of the said notch groove 14.
On the other hand, a lock piece 17 slides in the cutout groove 14 in a direction perpendicular to the axis of the upper horizontal rail 4 and can be projected and retracted from the front surface of the horizontal rail 4. A protrusion 18 is provided on both sides of the lock piece 17, and the protrusion 18 is engaged with the guide groove 16 and is guided by the guide groove 16 so that the lock piece 17 can be projected and retracted. Further, on the lower surface of the lock piece 17, a front face and a rear part are formed with a stopper surface 19 that comes into contact with the vertical surface 15a of the notch recess 15 or the back surface of the upper horizontal rail 4, and the movement of the lock piece 17 Is regulated.
[0015]
Thus, when the lock piece 17 is pulled out toward both sides, the front portion of the lock piece 17 protrudes from the front surface of the upper horizontal rail 4 by a predetermined amount, supports the lower surface of the front side frame 8, and the front side The lowering of the frame 8 is prevented. On the other hand, when the lock piece 17 is pressed, the lock piece 17 moves rearward, the front part of the lock piece 17 is notched into the recess 15, and the front side frame 8 can be lowered.
[0016]
Therefore, when the infant is in the bed, the front side frame 8 is held at the upper closed position by the slide latch 10 and the lock piece 17 is pulled out (FIG. 1). Even when the slide latch 10 is disengaged, the front side frame 8 is prevented from descending, and an accident of falling of an infant can be prevented.
[0017]
On the other hand, when the baby is taken in and out or when the diaper is replaced, the front side frame 8 can be slid downward by pushing the lock piece 17 into the notch 15 and then releasing the slide latch 10. it can.
[0018]
By the way, in the said embodiment, although what provided the 2nd locking device 13 in the upper crosspiece 4 was shown, you may provide the 2nd locking device 13 in the lower part of the front side frame 8. FIG. That is, the second locking device 13 is provided on the lower surface of the front side frame 8 in the direction opposite to that shown in FIG. The front side frame 8 may be prevented from being lowered. Further, instead of the second locking device 13, a slide latch 20 may be provided at the lower portion of the front side frame 8 as shown in FIG. In this embodiment, it is only necessary to attach an existing slide switch, and the cost can be reduced.
[0019]
【The invention's effect】
As described above, the present invention is provided with the second locking device for preventing the front side frame from descending on the front side frame on the long side or the upper horizontal rail connecting the middle part of the left and right corner columns. Therefore, even if the latch for holding the normal front side frame is removed, the front side frame does not fall naturally, and the infant can be prevented from falling. In addition, when the lock piece can be moved in and out, the configuration can be made extremely simple.
