The present invention relates to an improvement of a folding bed to make more efficient use of the interior space, and in particular, the bed is positioned horizontally on the floor by pulling forward while pulling the frame on which the mattress is mounted for the use of the bed. Folding type that makes it easy for anyone to operate the rotating frame of the mattress-mounted frame when you want to use it or to fold it vertically by pulling the frame with the mattress-mounted upward for the folding after use. It is to provide a frame rotating device of the bed.

In general, the bed is mainly used only for rest or sleep, and occupies a lot of indoor spaces when not in use, and thus becomes a barrier to efficient use of residential space.

In particular, when a general bed is used in a place such as a small house or a studio where the living space is narrow, it takes up a lot of space, and thus there are many difficulties in use.

Therefore, folding beds are provided for efficient use in places such as small houses or studios where the living space is small.

In other words, if you want to use the bed by rotating folding bed at the bottom of the front of the closet or various storage spaces, spread the bed horizontally when you don't want to use it. In this way, the residential space can be used more efficiently.

However, in the case of a folding bed that has been provided so far, the mattress-mounted frame is rotated while being pulled forward to be installed on the floor in a horizontal state, or rotated while being pulled upward for use of space after use. When the frame was to be folded upright, it was difficult to rotate the heavy bed so that it was not suitable for the elderly and the children, and the risk of a safety accident was caused.

The present invention in the construction of a folding bed for the efficient use of the living space to correct the problems of the conventional, the forward rotation operation for the use of the bed, and the vertical rotation to the rear for folding the bed after use The folding work is not hard and anyone can easily operate.

In order to achieve the above object, the present invention provides a conventional folding bed in which the frame on which the mattress is mounted is rotatably installed inside the lower end of the cabinet, and fixedly fixed to the fixed shaft on the side body of the cabinet. The frame on which the mattress is mounted is freely installed in an upright or horizontal state, but the frame on which the mattress is mounted is installed by elastically installing a tensioning spring which is spaced a certain distance from the fixed shaft and the fixed shaft which becomes the center of rotation of the frame. In the process of rotating forward to make the floor level with the floor, the tension spring increases, which strengthens the mattress and frame to support the weight of the mattress and frame, thereby significantly reducing the weight felt by the user who wants to rotate the bed forward. Mat for space after use When the user wants to fold the frame vertically, the user can easily fold the bed in the vertical position by adding the elastic force of the tension spring when the user pulls up the frame part with a small force by the force of the tension spring. .

Hereinafter, an embodiment of a folding bed to be provided in the present invention will be described in detail with reference to the accompanying drawings.

1 is a schematic perspective view of a folding bed 100 to be provided in the present invention, Figures 2 to 5 is a main state diagram of the present invention, the frame in which the mattress 130 is mounted on the inner bottom of the cabinet 120 ( 200 and horizontally and vertically configured to be rotatable, but in a state in which the frame 200 constituting the bed 110 is unfolded in a horizontal state, a wooden board (not shown) located in front of the bed 110 is vertically upright. It serves as a supporting leg while contacting the floor surface, and folding the frame 200 constituting the bed 110 in a vertical state for the space utilization is the same as the conventional folding bed that the wooden board serves as a cover and handle. .

However, the technical subject to be provided in the present invention is to install the mattress 130 on the upper surface of the frame 200 constituting the bed 110 by elastically installing the tension spring 210 to rotate the frame 200 to the front horizontal In the process of bringing the tension spring 210 increases as the tension of the frame 200 is reduced, on the contrary, when pulling the frame 200 upward and folding it in a vertical state, the tension spring 210 tries to restrain It is to provide a folding bed 100 that can be easily rotated even by applying a small force by pulling.

The above configuration will be described in more detail.

As shown in the drawing, a bracket 211 formed at the end of the fixed shaft 210 is positioned inside the lower end of the main body 122 of the storage cabinet 120 in which the storage space 121 is formed, and then fixed by fastening bolts 212. The shaft 210 is installed to be parallel to the inner bottom of the cabinet 120 side by side.

The fixing shaft 210 is installed in the center of the fixing body 214 is formed with a locking hole 213, but is fixed integrally without rotating from the fixed shaft 210 by using welding or locking means.

The folding bed 100 is configured by allowing the frame 200 on which the mattress 130 is mounted on the fixed shaft 210 to be rotated in a horizontal or vertical state.

The frame 200 is coupled to the fixed shaft 210 is as follows.

The frame 200 is manufactured to be generally configured to have a long shape, but the frame 200 is welded to the frame body 200 to be integrally fixed to the frame 200 by welding the rotating body 220 having a generally long guide groove 221 formed therein. In front of the rotating body 220, the support 230 is welded and fixed integrally with the frame 200.

As described above, the rotating body 220 and the support 230 which are integrally welded and fixed to the inside of the frame 200 are configured to be configured side by side on both sides of the frame 200.

In addition, the support member 230 has a bolt 243 formed in the front of the fixing plate 240 as shown in Figure 3 to be protruded forward through the support member 230 and then fastened with a nut 242, the nut 242 Rotating allows the fixing plate 240 to move back and forth with respect to the support 230.

When the guide groove 221 formed on the rotating body 220 in the above state is fitted to the outer surface of the fixed shaft 210, the fixed body 214 formed on the fixed shaft 210 is positioned in the rotating body 220, In the above state, the tension spring 250 is elastically installed between the locking hole 213 of the fixing body 214 and the locking hole 241 of the fixing plate 240.

As described above, when the nut 242 located in the front of the support 230 is rotated in the state in which the tension spring 250 is elastically installed, the fixing plate 240 integrally formed with the bolt 243 moves back and forth, The elasticity is adjusted.

Therefore, the frame 200 is held in the vertical or horizontal direction while being supported by the guide groove 221 of the rotating body 220 inserted into the fixed shaft 210 by the holding force of the tension spring 250 toward the fixed shaft 210. The rotation is free.

The upper and lower frames and the frame elastically installed around the fixed shaft 210 is attached to a conventional mattress 130 and a decorative wooden board (not shown) to form a folding bed (100).

The present invention configured as described above is to use the storage cabinet 120 is installed in the folding bed 100 is installed at the bottom of the furniture, such as a wardrobe or cabinet, such as a conventional folding bed, if you want to use for bed storage cabinet ( 120 to rotate the frame 200 on which the mattress 130 is mounted in a horizontal position and use it for a bed, and after use, the frame 200 on which the mattress 130 is mounted is placed in a vertical state. The folding and placing of the mattress 130 and the frame 200 into the storage space 121 of the cabinet 120 is to make efficient use of the residential space as in the prior art.

However, the folding bed 100 to be provided in the present invention rotates the frame 200 on which the mattress 130 is mounted forward to maintain the horizontal state, or rotates while pulling upwards to be folded vertically. Anyone can do it easily.

That is, when the frame 200 on which the mattress 130 is mounted is pulled forward and rotated, the frame 200 rotates forward with the rotating body 220 fitted to the fixed shaft 210.

However, since the fixed body 220 integrally formed on the fixed shaft 210 does not rotate, the distance between the fixed body 220 and the fixed plate 240 formed on the support 230 becomes gradually longer, and thus the fixed body 214. ) And the tension spring 250 elastically installed between the fixed plate 240 is extended.

In this case, as shown in FIG. 4, the fixing part of the tension spring 250, that is, the locking hole 213 of the fixing body 214, is positioned on the rear upper side of the fixing shaft 210, which is the center of rotation of the frame 200. In the 200, the force to rotate upward by the tension of the tension spring 250 is always operated around the fixed shaft 210, the tension of the tension spring 250 is rotated to the front frame 200 and the mattress Since the weight of the 130 is hardened, the weight of the mattress 130 and the frame 200 that the user feels is reduced, thus easily rotating the frame 200 on which the mattress 130 is mounted even with a small force. It can be positioned horizontally on the floor lightly without impact.

As described above, when the frame 200 on which the mattress 130 is mounted is rotated in a horizontal state to be used for a bed, and then the frame 200 is rotated while being pulled upwards to be used for a space, the frame 200 is folded in a vertical state. It will be easy to operate.

That is, as shown in Figure 4 in the frame 200 is in a horizontal state in the frame 200 because the fixed point of the tension spring 250 is located behind the fixed shaft 210 which is the center of rotation of the frame 200 is located in the frame 200 Always to force the tension spring 250 to act.

Therefore, in the above state by pulling the frame 200, the mattress 130 is mounted upwards and acts together with the resilient spring force of the tension spring 250, so that the user can easily assist the frame 200 without applying a large force. As in 5, it can be folded vertically.

As described above, if the tension force of the tension spring 250 is properly adjusted in the process of unfolding or folding the frame 200 in a horizontal or vertical state, the weight applied to the frame 200 can be adjusted.

The tension force adjustment of the tension spring 250 is adjusted by the nut 242 located in front of the support 230.

That is, in order to increase the tensile force of the tension spring 250, when the nut 242 located in front of the support 230 is tightened, the bolt 243 protrudes forward, so that the fixing plate 240 integrally formed with the bolt 243 is As the distance between the fixing body 214 and the fixing plate 240 is increased while moving forward, the holding force of the tension spring 250 installed therebetween becomes strong, and if the holding force of the tension spring 250 becomes strong, the frame ( Since the weight applied to the device 200 can be reduced by the weight, the weight of the frame 200 felt by the user is relatively reduced.

On the contrary, when the nut 242 located in front of the support 230 is loosened, the tension plate of the tension spring 250 decreases as the fixed plate 240 moves backward, thereby narrowing the distance from the fixture 214. The force that touches the weight of the frame 200 applied to the tension spring 250 is also reduced, so that the weight of the frame 200 that the user feels is slightly increased.

Therefore, when the folding bed 100 to be provided in the present invention intends to operate the frame 200 constituting the bed in a horizontal or vertical state according to the tensile strength of the tension spring 250 installed on the frame 200. Since it is possible to adjust the degree of weight felt, if the user adjusts to the optimal state, the user can easily operate the frame 200 in a horizontal or vertical state without a large force.

As described above, in the present invention, when constructing a folding bed that is used for efficient use of an indoor space, the horizontal or vertical folding operation of the frame constituting the bed can be easily operated by anyone. In addition, it is possible to provide a high-quality folding bed with high durability because it can reduce the impact on the fixed shaft portion by reducing the impact in the process of unfolding and folding the frame equipped with the mattress.
