BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a crib bed, and more particularly, to a crib bed having a simple structure and being easy to install and carry.

Recently, more and more people are enjoying camping as part of their leisure activities. As a result, demand for various camping equipment is also increasing. These camping equipments include tents, a simple chair, a simple table, a cot, and a cooking utensil.

Among them, a rollaway bed will help you to sleep more comfortably while avoiding the chill from the floor when you sleep outdoors. However, since these cribs must also be transported during camping, it is important to enhance portability by minimizing weight and volume during transportation.

Conventional portable cushions (see Japanese Patent Application Laid-Open No. 2001-3258) have a structure in which the respective components are housed while being separated while being carried, and assembled when used. However, it is impossible to control the height of the bed during use, and a cot that can adjust the height as needed is required.

In addition, a simple structure requires a rigid structure capable of sufficiently supporting the load while controlling the height of the crib bed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a liner according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

Referring to FIG. 1, a cradle 100 according to an embodiment of the present invention includes a seat portion 110 that provides a space in which a user can sit down or sit, and a support assembly (130).

Referring to FIG. 2, the seat portion 110 includes a pair of horizontal pawls 111 arranged side by side and a cloth 121 having horizontal pawls 111 at both ends thereof. On the other hand, the seat portion 110 is not limited to this, and may be composed of a mattress or a net structure.

The support assembly 130 includes an intermediate connection frame 131, a pair of upper support frames 141 extending upward from both ends of the intermediate connection frame 131, A pair of lower support frames 151 and a pair of connection hubs 161 connecting the upper support frames 141 and the lower support frames 151 at both ends of the intermediate connection frame 131.

Meanwhile, two or more supporting assemblies 130 are included in the seat 100, and the number of the supporting assemblies 130 can be changed by various factors such as the material of the elements, the weight, and the magnitude of the load to be borne.

Each upper support frame 141 has an upper end connected to the horizontal pole 111 of the seat portion 110 and a lower end connected to the end of the intermediate connection frame 131 by a connection hub 161. In addition, the upper support frames 141 may be connected to the intermediate connection frame 131 in such a manner that the upper support frames 141 are spaced apart from each other. Thus, the load transmitted from the seat portion 110 to the upper support frame 141 can be dispersed by the intermediate connection frame 131.

Each of the lower support frames 151 is connected at its upper end to the end of the intermediate connection frame 131 by a connection hub 161. At this time, the lower support frame 151 is detachably connected to the connection hub 161. 2 (a), when the lower support frame 151 is coupled to the connection hub 161, it can be used at a relatively high height. As shown in FIG. 2 (b) When the lower support frame 151 is separated from the connection hub 161, it can be used at a low height.

Since the lower supporting frame 151 is detachably connected, the height of the seat part 110 can be selected, so that the usability of the simple bed 100 can be improved and the lower supporting frame 151 It can be separated and stored, and the portability can be improved. Meanwhile, the manner in which the lower support frame 151 is engaged will be described in detail later.

Meanwhile, the intermediate connection frame 131, the upper support frame 141, and the lower support frame 151 may be hollow tubes. By doing so, the weight of the crib bed 100 can be reduced and the portability can be improved.

3, the connection hub 161 includes an intermediate connection portion 162 that is laterally opened and into which the intermediate connection frame 131 is inserted, an upper connection portion 163 that is opened upward and into which the upper support frame 141 is inserted, And an engaging hole 164 which is opened downward and into which the lower supporting frame 151 is inserted.

An end of the intermediate connection frame 131 is inserted into the intermediate connection portion 162 of the connection hub 161. That is, a pair of connection hubs 161 are connected to both ends of the intermediate connection frame 131, respectively. The lower end of the upper support frame 141 is inserted into the upper connection portion 163 of each connection hub 161. The upper end of the lower support frame 151 is inserted into the engagement hole 164 of each of the connection hubs 161.

The coupling hole 164 may be formed with an upper bent portion 165 bent inward to prevent the coupled lower supporting frame 151 from falling downward. This is explained in detail in Fig.

Meanwhile, the connection hub 161 may include two lower coupling holes 164 to couple the two lower support frames 151 to one coupling hub 161. Thus, the cushion bed 100 can more stably support the load, and more lower support frames 151 may be connected as needed.

4 and 5, the lower support frame 151 may be detachably coupled to the connection hub 161 by a connecting member 170 and an elastic stopper 180. [

The connecting member 170 is vertically opened and has a substantially cylindrical shape, and at its upper end, a plurality of elastic pieces 171 extending in the longitudinal direction are formed at predetermined intervals in the circumferential direction. By the elastic pieces 171, a plurality of cutting grooves 172 are formed in the upper end of the connecting member 170 between the respective elastic pieces 171.

The connecting member 170 has an upper coupling groove 173 formed along the outer periphery of the elastic pieces 171 for coupling with the coupling hub 161. The coupling member 170 may further include a lower coupling groove 174 formed along the outer periphery of the lower end for coupling with the lower support frame 151. In addition, the connecting member 170 may further include a lower bent portion 175 formed to be bent inward so as to restrict an excessive insertion of the elastic stopper 180 downward.

The elastic stopper 180 is inserted into the connecting member 170 to open the elastic piece 171 of the connecting member 170 in the outward direction. The elastic plug 180 has a protruding portion 181 formed at a predetermined interval in the circumferential direction on the upper outer peripheral surface. The elastic stopper 180 may have a bent portion on the outer peripheral surface between the lower end and the upper end so that the lower end has a smaller diameter than the upper end.

4 (b), the protrusion 181 of the elastic stopper 180 is inserted into the incision groove (not shown) of the connection member 170, 172. Accordingly, the elastic stopper 180 can stably fix the position in the circumferential direction within the connecting member 170, and can prevent the elastic piece 171 from moving in the circumferential direction.

The elastic pieces 171 of the connecting member 170 are opened outward by the insertion of the elastic stopper 180 so that the connecting member 170 is firmly fixed to the lower supporting frame 151. The elastic stopper 180 is prevented from being excessively inserted downward by engaging the bent portion between the upper end portion and the lower end portion with the lower end bent portion 175 of the connecting member 170. [ The lower end of the elastic stopper 180 is inserted into the lower end bending portion 175 of the connecting member 170 and pushes the lower end bending portion 175 in the lateral direction. Thereby, the outer circumferential surface of the connecting member 170 and the inner circumferential surface of the lower support frame 151 can be brought into close contact with each other.

5, when the lower support frame 151 is inserted into the coupling hole 164 of the coupling hub 161, the upper coupling groove 173 of the coupling member 170, which is exposed upward, And the upper bent portion 165 of the upper portion 161 is inserted. Thus, the lower support frame 151 is engaged with the engagement hole 164 of the connection hub 161.

When the upper bent portion 165 is inserted into or withdrawn from the upper engagement groove 173, the elastic pieces 171 of the coupling member 170 are temporarily deformed inward and recovered. That is, the elastic pieces 171 are elastically contacted with the connection hub 161. At this time, the elastic cap 180 is made of a highly elastic rubber material, which is preferable in that the elastic piece 171 is pressed outward to provide a stable fixing force at the time of coupling and can be separated by applying an appropriate force.

On the other hand, a ring-shaped coupling protrusion 152 corresponding to the lower coupling groove 174 of the coupling member 170 may be formed on the inner peripheral surface of the lower support frame 151. The lower support frame 151 can be more firmly fixed to the coupling member 170 by inserting the coupling protrusion 152 of the lower support frame 151 into the lower coupling groove 174 of the coupling member 170. [

An elastic piece 171, an upper coupling groove 173 and a lower coupling groove 174 are formed in the coupling member 170 so that the coupling hub 161 and the lower supporting frame 151 can be firmly fixed . By inserting the elastic stopper 180 into the connecting member 170, the fixing force of the lower supporting frame 151 is increased, and easy detachment is possible. The elastic stoppers 180 can be stably fixed to the connecting member 170 by inserting the protruding portions 181 into the cutout grooves 172 and engaging the bent portions on the outer circumferential surface of the elastic stopper 180 with the lower end bent portions 175. [ Lt; / RTI >
