Description

  The present invention relates to a bottom pivoting head structure of a baby bed, and by controlling opening and closing of a bed frame, operation is further simplified, stabilized, and the structure is simplified. In addition, when the entire frame is opened, the bottom frame is fixed to prevent a reduction due to malfunction, and after folding, simply turning the rods will arrange the bed's cloth surface, further reducing the overall size and reducing the volume. Things.

  In the well-known folding crib structure, a folding switch is installed on all four sides of the upper frame of the crib, and when the folding switch is pressed, the engaging protrusion set on the folding switch enters the folding switch unit. , Fold the frame. In addition, a pivotal head is installed at the bottom of the bed, and the pivotal head pivots the frame at the bottom of the bed, and the frame at the bottom is also folded.

  As an example, in the structure of the known document 1, a fixed base and a movable base are pivoted, and a plurality of fixed support rods are installed on the side of the fixed base. In addition, movable support rods are respectively installed on two opposing sides of the movable base, and engaging rods are fixed to other two opposite sides of the movable base. Elastic parts are installed between suitable positions of the movable support rod and the fixed support rod, and when each fixed support rod and the movable support rod are attracted in the same plane, the movable table rotates, and the hanging rod is further moved on the fixed support rod. Fold and support and fix each fixed support rod and movable support rod simultaneously. In addition, when the movable base is rotated and the hanging rod is removed from the fixed supporting rod and folded, the fixed supporting rod and the movable supporting rod are simultaneously folded by the elasticity of the elastic component.

However, the pivotal head structure described above is complex and has a direct impact on cost. Further, the assembly is not easy, and the stability is insufficient. Further, when the baby bed is folded, the baby bed wall surface and the cloth surface on the bottom face swell and cannot be folded firmly, so that the volume cannot be reduced. For this reason, the work becomes difficult when successively folded.

    The problems to be solved are that the stability of the whole baby bed is insufficient, and the structure of the pivoting head is complicated, so that the cost is increased and the operation is complicated.

  In the present invention, the outer and inner support legs are installed, and the outer and inner support legs overlap and are connected. A tank hole is separately provided on the outer support leg, a pivot shaft is fitted therein, and a hook tub is formed on the inner support leg. A compression spring connects between the pivot shaft and the shaft rod fitted to the outer and inner support legs. The shaft rod is pulled by the elasticity of the compression spring, the rod body is opened, the first and second joints are engaged with each other, and the first and second joints are engaged with each other and fixed. In addition, when the drawstring provided on the pivot shaft is pulled, the first and second joints are separated from the hook tub and separated and folded. Separately, the rod to be installed in the first and second joints has an elongated hole, and after folding the bed by installing in the elongated hole, rotate the rod a little to reduce the overall volume. The most important feature.

  The bottom pivoting head structure of the baby bed according to the present invention has the advantages that the stability of the whole baby bed is good, the structure of the pivoting head is simple, the cost is low, and the operation is simple.

As shown in FIG. 1, the pivot head structure of the present invention is installed at the bottom of the crib frame. As shown in FIG. 2, the structure of the pivot head includes a first joint 1, a second joint 2, a pivot 3, a shaft 4, and a plurality of compression springs 5. The main body of the first joint 1 is provided with downward and outward supporting legs 11 on both sides thereof, and a storage space 111 is provided inside the outer supporting legs 11. A cutout 15 is formed at the upper end of the main body between the two outer support legs 11, and an inclined tank hole 12 and a pivot hole 13 are formed at appropriate positions above and below the outer support legs 11, respectively. Through holes 14 are formed on both sides of the main body of the support leg 11 on each side.
Downward vertical inner support legs 21 are installed on both sides of the main body of the second joint, and the two inner support legs 21 are simultaneously placed between the two outer support legs 11 of the first joint 1. At the upper end of the main body between the two inner support legs 21, a plurality of convex lumps 23 placed in the cutout 15 of the first joint 1 are installed. An inclined hook basin 211 and a pivot hole 212 are formed at appropriate positions above and below the inner support leg 21, respectively. Further, the pivot hole 212 corresponds to the position of the pivot hole 13 of the first joint 1, and two sides of the through holes 22 are provided on the other side of the main body of the inner support leg 21.

The shaft rod 4 is inserted into the pivot hole 13 of the outer support leg 11 of the first joint 1 and the pivot hole 212 of the inner support leg 21 of the second joint to connect the first and second joints 1 and 2, The two inner support legs 21 are placed between the two outer support legs 11 and overlapped. Separately, the pivot shaft 3 is inserted into the tank hole 12 of the first joint 1. The shaft rod 4 and the pivot shaft 3 are engaged by a compression spring 5 and are connected by the compression spring 5. Also, the compression spring 5 is stored in the storage space 111 of the outer support leg 11 so that the external appearance of the entire pivoted head can be clearly seen (see FIG. 7). Further, the pivot shaft 3 is pulled downward in the tank hole 12 by the elastic force of the compression spring 5. In the four rods 6 pivotally mounted on the pivotal head, elongated holes 61 are formed on the relative wall surfaces near the ends, and the rods 6 are inserted into the through holes 14 and 22 of the first joint 1 and the second joint 2. After that, the pin 62 is passed through the elongated hole 61 to connect the first and second joints 1 and 2 (see FIGS. 3 and 5).

The drawstring 7 is installed on the pivot shaft 3 having the above-described structure (see FIG. 3), and by pulling the drawstring 7, the pivot shaft 3 is disengaged from the hook tub 211 of the second joint 2. Open and separate the second joint (see FIGS. 4 and 6). When the first and second joints 1 and 2 are engaged, the pivot shaft 3 is inserted into the hook basin 211 by the elastic force of the compression spring 5 to fix the first and second joints 1 and 2. Since the operation is simple and the structure is simple, the manufacturing cost is also reduced.
In addition, when the pin 62 is pivotally provided in the elongated hole 61 of the rod 6, when the crib is folded and the rod 6 is further rotated, the expanded bed cloth surface is arranged to further reduce the volume. Therefore, it is easier to store.

FIG. 3 is an overall perspective view of the pivot head according to the present invention installed at the bottom of the crib. FIG. 3 is an exploded view of parts of the pivot head according to the present invention. FIG. 4 is a three-dimensional view of a state of the present invention when the pivotal head is closed. FIG. 3 is a perspective view of the pivotal head of the present invention when it is opened and separated. FIG. 3 is a plan view of the present invention when the pivot head is closed. FIG. 4 is a plan view of the pivotal head of the present invention when it is completely opened and separated. FIG. 7 is an overhead plan view of FIG. 6.
