  The utility model will be described in detail below with reference to examples and drawings. In these drawings, the same reference numbers indicate the same or equivalent parts of this utility model.

  The drawings show a preferred embodiment of this utility model electric bed.

According to FIG. 1 and FIG. 2, the electric bed of this embodiment includes a bed frame 1 including two mutually parallel longitudinal rods 11 parallel to the longitudinal direction of the bed frame 1, and
A fixed bed frame 2 fixed to the bed frame 1;
A drive motor 4 that drives and tilts the bed bed 3 to be folded;
A link mechanism that connects the bed frame 3 and the bed frame 3 that can be folded and the drive motor 4;
A pair of handrails 6 provided on the bed frame 1;
Three folding bed platforms provided in the bed frame 1,
Including
The three folding bed platforms include a bed frame that can be folded on the head side, a folding bed frame that supports the thigh, and a folding bed frame that supports the shin, and the folding bed frame 3 described below is a bed that can be folded on the head side. Two vertical slide rails 31 are attached to the bed bed 3 to be folded, and the vertical slide rails 31 are close to one side of the bed bed 3 to be folded.

The link mechanism is provided between two longitudinal rods 11 and has a lateral drive bar 53 that can rotate with respect to the bed frame 1 with the central axis of the lateral drive bar as a rotation axis. ,
One end thereof is fixed to the lateral drive bar 53 and can be rotated together with the lateral drive bar. A slide block 511 is provided at the other end, and the slide rail 511 of the bed frame 3 on which the slide block 511 is folded is attached. A pair of first connecting rods 51 slidable along,
A pair of second connecting rods 52 provided on the bed frame 3 that is provided at the bed frame 1 so that one end thereof can be rotated and the other end can be rotated,
One end thereof is provided on the longitudinal rod 11 so as to be rotatable, and the other end includes a pair of support arms 54 provided on the bed frame 3 which is folded so as to be rotatable.

  One end of the drive motor 4 is fixed between two longitudinal rods 11 of the bed frame 1 and the other end is connected to a lateral drive bar 53 so as to be rotatable.

  3a to 3d show a process in which the degree of inclination of the bed frame 3 in which the electric bed of the embodiment is folded is raised from low to high.

  In this process, the bed frame 3 that is folded first is in a horizontal state (not shown), and at this time, the first connecting rod 51 and the second connecting rod 52 of the link mechanism are all in a horizontal state, The slide block 511 on the rod 51 is on the top of the slide rail 31, that is, on the edge closest to the bed frame 3 to be folded. In the process of raising one side of the folding bed frame, the drive motor 4 drives the horizontal drive bar 53 and rotates it around its center. Then, the first connecting rod fixed to the horizontal drive bar 53 is fixed. One end of 51 is raised, and one side of the bed frame 3 to be folded is raised by one end of the raised first connecting rod 51. At the same time, the slide block 511 provided at the end of the first connecting rod 51 is folded. Since the slide rail 31 of the bed frame 3 is slid and one end portion of the folding bed frame 3 is raised, the length of the second connecting rod 52 connected to the folding bed frame 3 is a constant value. One side that cannot be raised is moved horizontally in the direction of the longitudinal rod 11 of the bed frame 1 so as to be separated from the fixed bed frame 2 by the second connecting rod 52, Since the length of the support arm 54 does not change, the horizontally moving one side of the bed base 3 that is folded is separated from the fixed bed base 2 and at the same time is slightly raised by the support arm 54. 1 is not in contact with the longitudinal rod 11. When one side of the folding bed frame 3 is raised to the highest position, as shown in FIG. 3d, the slide block 511 on the first connecting rod 51 is at the lower end of the slide rail 31, that is, the bed frame on which the slide rail can be folded. 3 at the end closest to the middle position.

  4A is a bird's-eye view of the electric bed when the bed bed 3 to be folded is in a horizontal state, and FIG. 4B is a bird's-eye view of the electric bed when the bed bed 3 to be folded is most inclined. According to FIGS. 4a and 4b, when the folding bed frame 3 is changed from the horizontal state to the largest tilted state, one side of the folding bed frame 3 that moves horizontally is moved by the distance S, and the distance S is about 3 to 8 cm. Therefore, S = 5 cm is preferable. In this case, the user feels best and can also protect the mattress.

  The process of bringing the folding bed frame 3 into the horizontal state is opposite to the process of raising the inclination, and the drive motor 4 slowly rotates the lateral drive bar 53 in the opposite direction, so that the first connecting rod 51 is moved horizontally. The slide block 511 on the first connecting rod 51 is slid from the bottom end of the slide rail 31 to the tip, and the bed base 3 that is folded is also rotated and raised so as to be in a horizontal state. At the same time the side is slowly lowered, the second connecting rod 52 moves the unfolded side of the folding bed frame 3 horizontally toward the fixed bed frame 2. At this time, the folding bed frame 3 is in a horizontal state by the support arm 54. The horizontal moving side of the bed bed 3 that is folded still does not come into contact with the longitudinal rod 11 of the bed frame 1 until it returns to.

  In addition, as shown in FIG. 5, at the moment of returning to the horizontal state, in order to relieve the collision or friction between the folding bed frame 3 and the longitudinal rod 11 of the bed frame 1, or when there is a load on the electric bed In order to prevent the folding bed frame 3 and the longitudinal rod 11 of the bed frame 1 from colliding or rubbing, the folding bed frame is provided with a friction heel block 32.

  As shown in FIG. 5, each friction heel block 32 has two flanges 321, and the distance between the two flanges 321 is slightly larger than the width of the longitudinal rod 11, so that the longitudinal rod 11 has two flanges 321. The frictional heel block 32 is interposed between the folding bed frame 3 and the longitudinal rod 11 of the bed frame 1. It came to be. In addition, each friction heel block 32 may have a fixing hole 322. By using such a fixing hole 322, the friction heel block 32 is fixed to the bed base 3 that can be folded. It is possible to more effectively prevent sliding of the folding bed base 3.

  FIG. 6a shows the state of the friction heel block 32 when the folding bed frame 3 is in a horizontal state. FIG. 6 b shows the state of the friction heel block 32 when the bed bed 3 to be folded has the greatest inclination. According to FIG. 6a, when the bed base 3 to be folded is in a horizontal state, the friction heel block 32 and the longitudinal rod 11 of the bed frame 1 are brought into contact with each other, and the collision and friction can be reduced. If the bed bed 3 to be folded has the greatest inclination and there is no load on it, the frictional heel block 32 does not come into contact with the longitudinal rod 11 of the bed frame 1 as shown in FIG. When the bed cradle 3 falls on the bed or when the bed is loaded, the folding bed pedestal 3 is lowered by gravity and comes into contact with the vertical rod 11. It acts as a shock absorber intervening between the two.

  The above embodiments are merely examples, and do not limit the scope of the utility model. On the basis of this, those skilled in the art can imagine other implementations that can achieve the same function within the scope of the claims of this utility model. For example, the combination of a slide block and a slide rail is replaced with a combination of a slide block and a concave groove, or a combination of a pulley and a slide rail. The position of the guard rail is not limited to the position described in the embodiment, and the link mechanism is An “X” -shaped link mechanism may be substituted, and the mechanism is not limited to being provided on the head side.

  Those skilled in the art know a plurality of embodiments and modifications and their improvements, and the above features, modifications, and / or specific embodiments of this utility model, except for situations where there are obvious contradictions or situations where they cannot be combined, Can be combined. All embodiments, variations and improvements are all within the scope of protection of this utility model.
