Description

[Detailed explanation of the idea] <Industrial application field> The present invention relates to a folding bed.

<Conventional technology> Most conventional folding beds have to be folded by lifting both the front and rear legs, which takes a lot of effort. It was too tall for a child to hold, and it was expensive.

<Problems to be Solved by the Invention> In view of the above-mentioned circumstances, the present invention aims to provide an inexpensive folding bed that can be easily folded even by children by lifting only the rear legs and folding the middle part.

<Means for solving the problem> The side frame is made to be foldable in the middle using a parallel crank, and one end of the lower part of the parallel crank is extended to form a middle leg with a roller to make it easier to step on, making it easy for even children to fold. I made it possible. By eliminating unnecessary parts, we made it lighter and made it an inexpensive folding bed.

<Function> In order to fold the bed in a stable state, the front leg is fixed to the intermediate leg that slides on rollers, and the other end of the front frame that was in contact with the front leg is
need to be lifted. For this purpose, two link members are pivotally attached between the front legs and the front frame to ensure smooth folding.

On the other hand, the rear legs are folded by lifting them, but after lifting the rear legs, it is necessary to fold them vertically. For this reason, two link members are pivotally attached between the rear legs and the rear frame, so that the rear legs can be folded.

In addition, since the operation of the rear frame will be unstable if only the parallel crank is used, one of the front frame link members pivotally connected between the front legs and the front frame is protruded above the side frame, and an upper The other end of the rear frame link member, which was pivotally attached with a pin, was pivotally attached to the rear frame to function as a fall prevention fence.

<Embodiment> The attached FIG. 1 shows an assembled folding bed showing an embodiment of the present invention, FIG. 2 shows the same folding process, and FIG. 3 shows the same folded state.

One end of the front side frame 2 and one end of the rear side frame 3 of the side frame of the bed are pivotally connected by the parallel crank 1, and when assembled, one end 2a of the front side frame 2 and one end 3 of the rear side frame 3 are connected.
a comes into contact with the abutting state, and when folded up, it is erected on the side frames 2, 3 with one end 2a, 3a facing down.

One lower end of the parallel crank 1 is extended and bent into a U-shape with a bottom parallel to the width direction W of the bed, and both ends are pivoted near one end 2a of the front frame 2, and during the folding process. Rear B as shown in Figure 2
He fell to the side and was slid. For this purpose, a slidable roller 5 is provided on the bottom surface of the intermediate leg 4. Therefore, the two side frames 2 and 3 which are parallel to each other are connected to the connecting rods 6, 6, 7, 7 to form the frame bodies 8, 9.
It consists of These frames 8 and 9 have mats 1
0 and 11 are fixed with bolts and integrated to prevent wear.

The folding bed of the present invention is supported by front legs 12 and rear legs 13 in addition to the intermediate legs 4. The front leg 12 has an upper part bent in a U-shape to form a head frame, and the rear leg 13 also has an upper part bent in a U-shape to form a mat frame.

The front leg 12 and the front frame 2 are pivotally connected by two link members. That is, both ends of a front leg link member 14 are pivotally connected between the front leg 12 and the front frame 2 by pins 15 and 16, and the front leg link member 14 supports the front frame 2 when the bed is assembled and raised. Play a supporting role. On the other hand, the other end of the front leg 12 that protrudes downward is pivotally attached to the lower end of the front leg 12 with a pin 17, and the middle part is pivoted with a pin 18 at a position slightly closer to the rear B than the pin 16 of the front frame 2. A front frame link member 19 with one end projecting upward is provided. One end of the front frame link member 19 is pivotally connected to one end of the rear frame link member 21 by an upper pin 20, and the rear end of the rear frame link member 21 is
It is pivotally mounted in the middle of the rear frame 3 with a pin 22, and does not extend downward. The upper pin 20 is bent upward during folding.

The rear legs 13 and the rear side frame 3 are pivotally connected to two link members, and are fixed by a fixing piece 23 during assembly. That is, the rear leg 13 and the rear frame 3 are pivotally connected to the rear leg upper link member 24 by pins 25 and 26 at the slightly upper side of the rear leg 13 and near the other end of the rear side frame 3, and pins 28, 2 near the other end of the rear frame 3 to the rear leg lower link member 27.
The fixing piece 23 is rotatably attached to the rear leg 13 with a pin 30, and the engagement groove 31 at the tip end of the fixing piece 23 is engaged with a pin 32 near the other end of the rear frame 3. Fix it. Therefore, the rear leg 13 is the third
With the frames 2 and 3 on both sides standing vertically and folded up to the position indicated by the dotted line in the figure, attach and detach the fixing piece 23,
Fold the rear legs 13 vertically in the direction of arrow A to complete the folding.

When the bed is assembled and stood up, the other end 2b of the front frame 2 is fixed to the front leg 12, and the other end 3b of the rear frame 3 is fixed to the rear leg 13 in a protruding state.

<Effects of the invention> The folding bed of the invention has husband pins 15, 16, 1 so that the front and rear side frame link members 19, 21 and the front leg link member 14 can rotate in a well-balanced manner.
Since positions 7, 18, and 22 are selected, it can be folded smoothly.

Furthermore, the intermediate legs 4 are slidable by the rollers 5, providing an inexpensive, useful and practical folding bed that can be folded and assembled with light force.
