The present invention relates to a double bed that is changed to a single bed when folded and stored in a lower bed while the lower bed is set up on the upper bed, especially when the legs are extended, It is about the bed either.

The double beds proposed prior to the present invention include Japanese Patent Laid-Open Nos. 60-95054 and 60-175163. However, the bedding (also called a second mattress or a small bed) in these prior arts has a structure in which the legs mounted beneath it can be folded and raised, but the standing position is unstable. This is because it is just as opened and does not have a holding device, so it is easy to be folded or retracted at any time when the pressure applied from the opposite side of the unfolding direction is applied.

The present invention is just an improvement. In other words, if you set a space for a bed in the bed and store it in a bed, it will be converted into a single bed. If you take out a bed from the bed, it will be a double bed for two people. In addition, by adding a stabilizer to the leg folding device of the bed, the extended position is maintained intact even when the external force is applied in a direction opposite to that when the leg is extended, and after the safety device is released, It was reorganized to stabilize the legs of the sleeping bed spread by attaching to the bed.

Hereinafter, a preferred embodiment of the present invention will be described in more detail.

The bed 1 is composed of a mother bed 100 and a bed 200. The mother bed 100 is suspended on the flat rectangular bed frame 101 with the cushion assembly 102 suspended thereon, and a base plate 103 such as plywood is fixed to the bottom of the bed frame 101 with screws 104. The bed frame 101, the cushion assembly 102, and the support plate 103 are fixed with screws 104, and the bed frame 101, the cushion assembly 102, and the support plate 103 are fixed to the bed 106. , Sponge 107, wrapped in a patch 108 to prevent the unsightly appearance from appearing to form a bed frame 105, and under the short side of the bed frame 105, the leg member 110 is set up.

In addition, the leg member 110 is formed under the four corners of the bed frame 105 by forming a screw 112 on the upper end of the leg 111, the support plate (113) attached to the lower end of the leg 111 ( The bolts 115 placed in the center of the upper surface of the 114 are screwed to be used for fine adjustment of the height. The mattress 120 is placed on an upper portion of the bed frame 105 surrounded by the outer shell, and a decorative cloth 121 is wrapped around the leg 11 to cover up.

On the other hand, the bed 200 is composed of a bed frame 210, a leg 220 and a folding device 230. Bed frame 210 is also placed on the mattress 211. Leg 220 of the bed 200 is made of a metal material having a U-shaped cross-folded folded to change as shown in FIG. 6a when folded, and folded as shown in FIG. As shown in FIG. 8, the leg folding apparatus includes a support plate 240 and a leg support piece 250 for the operation lever, an operation lever 260 and the folding section 270, and a link 280.

The legs 220 are axial holes 221 and 222 perforated at the top and middle height, and pivots 223 and 224 are formed by inserting pivots 223 and 224 formed with collars 223 a and 224 b in the middle from the outside. ) Is supported by the shaft hole 252 of the leg support piece 250 and the pivot 224 of the middle half of the activity hole when the inner half is loosely inserted into the activity hole 272 of the folding section 270 to fold and unfold. 272). In addition, near the edge of the leg 220, the threaded hole 225a is welded with the lean flat H-shaped support piece 225, and the bolt hole 255a is fitted with the bolt 226b of the support 226. When the legs 220 are folded to form a ground.

The operating lever support plate 240 is fixed to the inner side of the short side of the bed frame 210 with a screw 241, and both side holes 242 and 243, the operating lever support pivot 263 and the link 280 is formed in the middle of the link 280 ) And the pivot 276 penetrating through the folding section 270 are respectively supported.

In addition, the leg support piece 250 forms a pair with the support plate 240 for the operation lever, is fixed to the inner back front of the long side of the bed frame 210 with a fixing screw 251, the shaft hole 252 drilled in the intermediate position ) Is fitted into the inner portion of the peak support pivot 223 of the leg 220. Accordingly, the leg 220 can be folded or unfolded at an obtuse angle with the pivot 223 almost in parallel with the bed frame 210.

The operation lever 260 is bent in a letter C. The shaft holes 261 and 262 are drilled in the vicinity of the outer and inner ends of the sides, respectively, and the support plates 240 and the shaft holes 242 and 262 of the operating lever 260 are aligned. The pivot 263 is sandwiched between these shaft holes 242 and 262 in a state where the image is centered so that the pivot lever 263 is pivoted in position while the pivoting lever 260 is supported.

The folding section 270 punctures the shaft hole 271 and the N-shaped activity hole 272 at both ends, and forms a streamlined protrusion 273 at the front end of the shaft hole 271. The shaft hole 271 of the folding section 270 coincides with the inner shaft hole 243 of the operating lever support plate 240 and connects the pivot hole 276 therein, and the activity hole 272 has an intermediate pivot of the leg 220. The washer 274 and the C ring (275) is fixed to the ring groove (224b) protruded outward to be inserted into (224). When assembled, the pivot 224 is folded under the guidance of the activity ball 272, and the pivot 224 of the extended leg 220 is caught in the activity ball 272 that is curled up from the inner end. Finally, the extended position of the leg 220 is stabilized.

The link 280 is perforated or fixed with shaft holes 281 and 282 on both sides, and an outward fixing pin 283 in the center, and the outer shaft hole 281 is centered on the inner shaft hole 261 of the control lever 260. The center pin hole 282 is connected to the shaft hole 276 drilled at the tip of the folding section 270, and the fixing pin according to the up and down turning motion of the folding section 270. As the 283 is driven, the protrusion 273 of the folding section 270 is forcibly contacted so that the locked state can be fixed or released.

12 and 13 is another embodiment of the present invention, casters (300,301) having a stop button (300a, 301b) in place of the support (114,226) installed on the legs (110, 220) of the bed 100 and the bed 200 ) To give mobility. The caster 300 may be installed only on the rear leg 110 among the legs 110 of the mother bed 100. However, this change is well known in the bed sector.

In the present invention configured as described above, FIG. 1 is a modified example of a double bed, FIG. 2 shows a state in which a bed is taken out to be inserted into a concealed bed or a double bed. It is shown. 6A and 7A show the state when the bed 200 is unfolded, and FIGS. 6B and 7B show the case where the bed 200 is folded, respectively.

When you want to use the bed 200, the bed 200 is pushed out to cover the concealed bed 200 is used to extend the leg 220 of the bed 200. Next, the procedure for unfolding and folding the leg 220 of the bed 200 will be described.

First, when the operation lever 260 is pushed up in the direction of the vertical arrow of FIG. 10a, the operation lever 260 pivots like a two-point break line about the pivot 263, and the inner end of the operation lever 260 is lowered oppositely. Accordingly, the link 280 connected to the pivot 284 at the inner end pivots downward about the pivot 276. On the other hand, since the pivot 276 at the inner end of the link 280 is fixed to the operating lever support plate 240 and cannot move up and down, the link 280 has a free end side (outer end) around the pivot 276. You will turn down. Accordingly, as the fixing pin 283 pushes the protrusion 273 of the folding section 270 downward by the pivoting movement of the link 280, the folding section 270 is counterclockwise about the pivot 276. You will turn.

As a result of the counterclockwise turning movement of the folding section 270, the free end of the activity ball 272 also rises like the two-point breaking line of FIGS. 10a and 11, so that the pivot 224 of the leg 220 moves the activity ball 272. Outside of the inner bent side of the Subsequently, when the force that lifts the bed frame 210 is removed, the weight falls automatically by the weight of the bed 200, and the pivot 224 of the leg 220 is folded into the long side of the activity ball 272, so that the leg ( 220 is to be folded by pivoting around the pivot (223). At this time, the leg 220 is no longer folded when the pivot 224 is caught at the end of the long side in the pupil hole 272, the support 226 is in contact with the ground as shown in 10b. If both legs are folded like this, it becomes like FIG. 6 and FIG. 7B.

The intermediate support pivot 224 of the leg 220 moves along the activity hole 272 of the folding section 270 and is applied to the bed frame 210 when it is located at the bent end of the activity hole 272. By removing the pivot 224 is to be folded to the side of the bent end of the active hole 272 to fix the stretched leg 220 (figure 6 and 7a state).

The above folding is simply made according to the momentary movement of lifting and lowering the bed frame 210. The feet 114 and 226 attached to the legs 110 and 220 of the mother and mother bed 100 and 200 are to allow the sliding movement smoothly in contact with the ground, and instead of the supports 114 and 226, the casters 300, 300a, b, 301 and 201. If you change to a, b), you can use cloud movement to add convenience.

In this way, the present invention is a double bed consisting of a mother bed and a sleeping bed, when the chair is not in use, fold it up and put it in the bed, and when using, take out the bed and stretch out the legs. Since the posture of the legs is stable during use, it can be used with confidence, surpassing the existing bedding in terms of safety, and it is much less effortless to fold and unfold the legs by lever lever linkage between the operation lever, link and folding.
