Description

[Detailed description of the invention] This invention relates to a baby crib.

In recent years, cribs with various structures have been devised so that the entire bed can be folded into a compact shape in case of inconvenience. In a crib turtle frame with a framework of Attached to the X-shaped left and right connecting villages that are rotatably attached to the bracket at the other end of the side punch of the bottom punch above, a strong framework is obtained when in use, and the bed can be folded easily and smoothly. An application has already been filed for a device that can be folded into a
No. 333). This invention further simplifies the structure of the crib according to the above-mentioned earlier application, in which one ends of the front and rear vertically connecting punches are attached to approximately the center of the lower village portions of the front and rear frames, and A strong framework is created by attaching the other end to one end of the cross-shaped connecting village, and then attaching the pond end of this connecting pestle to the lower support punch provided between the lower ends of the front and rear frames by the horizontal connecting village. The purpose is to provide a crib that can be easily folded.

An embodiment of the present invention will be described below with reference to the drawings. Figures 1 through 5 show a crib according to one embodiment of the present invention. In the figure, "L2" is a U-shaped front frame having left and right side village parts a, lb, 2a, 2b, and lower part lc?2c, respectively, and the lower punch of the front frame turtle. Casters 3a and 3b are attached near both ends of the tortoise c.Front and rear frames 162, upper end bent portions la, lb, 2a, 2b of both sides of the tortoise &2d
The central village portions (upper village portions) 4a, 5a of the U-shaped front and rear upper frames 465 are rotatably attached by brackets 6, and the left and right side village portions of the upper frames 4, 5 are rotatably attached to the U-shaped front and rear upper frames 465.

0 and 21 are rotatably attached to the other ends of first and second coupling members 22 and 23, which are rotatably connected to each other in an x-shape. The first and second momentum-related punches 24, 25 are inserted into the through holes at the other ends of the punches 22, 23, and both ends of the horizontal linking holes 249, 25 are connected to the brackets 17b of the lower frames 15, 16. , ITa.

Note that the bottom, front and back, and both sides of this crib are covered with nets (not shown), and when in use, a futon is spread over the bottom.

However, since this baby B bed cannot be folded in the width direction, you may want to cover the front and back with hard sheets instead of netting. Next, we will explain how to use this crib.

The official drawing shows this crib in an open state, and in this state, the upper frames 4 and 5 have a cylindrical member 14.
The stopper 13 hits the head of the rivet 9, and the cylindrical member 4 is iron-plated across the front and rear side punch parts 4b, 5b, 4c, and 5c.
The side village portions 4b9 5bP 4c, 5c are locked to each other linearly.

In addition, in the lower frames 15 and 16, "side village wing 5b
? 35c, 16b, 16c bracket 1739 1
7b are partially overlapped and locked to each other L. As a result, the side village portions 15b, 16b, 15c, and 16c are also linear, and the vertical linkages 20 and 21 are connected to the side village portions 15b, 5c, and 5c. , 16b, and 16c. When folding the Baby Nagi bed from this state, first hold the cylindrical member 14 in your hand and move it in the direction of arrow B to move the cylindrical part tatami 4 to the side part of the upper frame 5. If only 5b and 5c are iron-clad, the locks of the side punch parts 4b?4c, 5b, and 5c of the upper frames 4 and 5 will be released and they will move downwards due to their own weight, that is, arrows C and D.
Rotate slightly in the direction.

Therefore, in this state, is the central punch portion 15a of the front or rear lower frame turtle 5.16 projecting outward from the bed? When stepping on 16a, the lower frames 15 and 16 rotate upwards around the pin 26, that is, in the direction of arrows E and F, and the sides of the lower frames 15 and 16 rotate in an inverted V-shape. , As a result, the interval between the front and rear frames ], 2 becomes narrower, and the upper frames 4 and 5 are further rolled in the C and D directions, and the side punch portions 4
b, 5b9 4c, 5c become V-shaped and
The rear vertically connected punches 20 and 21 are curved upward to form an inverted V shape. Then, when the front and rear frames 182 are brought closer to each other, the front frame body moves to the rear frame 2 side while remaining parallel to the rear frame 2, and the bed is moved! It is then folded into the state shown in FIG. Here, lower frame 1
The side village turtles 5b and 15c of No. 5 and the vertical connection village 20 and the side village portions 16b and 16c of the lower frame 16 and the vertical connection pestle 21 are in a substantially parallel state during and when the bed is folded. It remains as it is. In addition, when opening the bed from the folded state, the operation is the exact opposite of the above.

In the crib of this embodiment as described above, when the bed is opened, the front and rear frames 1 and 2 are also connected to the upper frame 4.

4, 25 to lower frame bracket 17a, 1
Since it is attached to 7b, only one set of connecting bolts is required, making the structure very simple and manufacturing easier.

In addition, since the framework is formed using the U-shaped frames 1, 2, 4, 5, 15, and 16, the number of connecting points can be reduced, which also simplifies manufacturing.
In addition, in this crib, the side villages 4b, 5b, 4c, and 5c are locked in a straight line by iron-fitting the cylindrical member 14 to the village parts 4b, 5b, 4c, and 5c on both sides of the upper frames 4 and 5. The structure of the locking means is very simple. In the above embodiment, the upper frame and the upper branch frame are integrally formed to connect the upper ends of the front and rear frames, but the upper frame and the upper branch frame may be separate bodies. Also, in the above embodiment, the side village portion and the lower village portion of the front and rear frames are integrally formed, but the side village portion and the lower village portion may be separate bodies.Also, in the above embodiment In this case, the lower ends of the front and rear frames are connected by a U-shaped lower frame, but the lower ends of the front and rear frames are connected only by the side villages of the lower frames, that is, only by the lower branch. Also, in the above embodiment, locking means are provided on both punches of the upper frame, but this locking means may be provided only on one side village of the upper frame, or on the side of the lower frame. It may also be provided on the punch.

Further, in the above embodiment, a cylindrical member is used as the locking means, but this locking means may have another structure.
Furthermore, in the above embodiment, one end of the right upper branch of the front and rear frames is rotatably attached to the upper end of the side punch part of the front and rear frames. It may be rotatably and slidably attached to the side punch part so that the upper branch can be locked at the upper end position of the side punch part, and in this case, infants can be taken in and out easily.

As described above, the baby bed according to the present invention has front and rear vertically connecting villages approximately in the center of the lower village of the front and rear frames, and is connected to both the ribbed connecting villages in an X-shape. By attaching the connecting punches to the lower supporting punches installed between the lower ends of the front and rear frames by the staff in charge of transportation, a strong framework was obtained with a simple structure, and it was easy to operate. This has the effect of allowing the bed to be folded up smoothly.
