  As shown in FIG. 8, a gap α is formed between the end of the foot side F in the oblong hole 56a and the pin 53a. Thus, even when the first drive mechanism 53 is stationary, the back bottom 21 can be rotated in the vertical direction around the bottom hinge 64d within the gap α. For example, when there is no gap α, the end of the head side H of the back bottom 21 may be pressed against the second vertical member 37 by the driving force of the first driving mechanism 53.

(Leg bottom)
As shown in FIG. 1, the leg bottom 23 includes a knee bottom 24 and a foot bottom 25. The knee bottom 24 and the foot bottom 25 are arranged in this order from the head side H to the foot side F. The knee bottom 24 supports the waist from the user's knee. The foot bottom 25 supports the foot tip from the user's knee.
The knee bottom 24 and the foot bottom 25 are connected so as to be rotatable around a bending shaft 27 extending in the left-right direction. Therefore, when the knee bottom 24 rotates around the bottom hinge 64e, the leg bottom 23 bends upward so that the bending shaft 27 forms a vertex.

  Knee bottom support plates 69 are fixed to the left and right ends of the knee bottom 24, respectively. The knee bottom support plate 69 is formed with a through hole penetrating the knee bottom support plate 69 in the left-right direction. Since the through hole of the knee bottom support plate 69 and the bottom hinge 64e of the side member 64 are inserted by a common pin, the knee bottom 24 rotates in the vertical direction around the bottom hinge 64e.

A foot bottom support plate 67 is fixed to each of the left and right ends of the foot bottom 25. The foot bottom support plate 67 supports the foot bottom 25. The distance between the foot bottom support plate 67 and the side fence 13b is, for example, less than 60 mm. The distance between the foot bottom support plate 67 and the side fence 13b satisfies the requirements defined in the IEC standard.
As shown in FIG. 3, two sliding members 28 are attached to the foot side F end of the foot bottom 25. The sliding member 28 is formed of a material having excellent slidability such as industrial resin.

  As shown in FIG. 9, the sliding member 28 has a mattress restricting portion 28a (second mattress restricting portion), an attaching portion 28b, and a sliding surface 28c. The attachment portion 28b is formed in a C shape in a side view and sandwiches the foot bottom 25. The mattress restricting portion 28a extends upward from the end portion on the foot side F of the upper surface of the attachment portion 28b. The mattress restricting portion 28a extends upward from the mattress placement surface of the foot bottom 25. The sliding surface 28c is the lower surface of the attachment portion 28b.

  Next, the operation of the bed apparatus 10 configured as described above will be described.

  When the second drive mechanism 54 is driven, the knee bottom 24 rotates about the bottom hinge 64e. In conjunction with this, the foot bottom 25 rotates around the bending shaft 27. At this time, as shown in FIG. 9, the sliding surface 28 c of the sliding member 28 attached to the foot F side end of the knee bottom 24 slides on the second vertical member 37 of the main frame 32. Thereby, it can prevent that the edge part of the leg bottom 25 and the 2nd vertical member 37 slide directly, and peeling of a coating etc. arise.

  As described above, according to the bed apparatus 10 according to the present embodiment, the side material 64 disposed on the lateral side portion of the waist bottom 22 regulates the position of the mattress by the mattress regulating portion 64a, and the bag. Since it has a function of holding the urine collection bag by the holding part 64b and a function of regulating the belt position by the belt receiving part 64c, these functions can be realized with a simple configuration.

  Furthermore, since the mattress restricting portion 64a extends upward, the distance between the side member 64 and the side rails 13a and 13b satisfies the requirements defined in the IEC standard, so the configuration is simple. It is possible to prevent an object or the like from being caught between the side member 64 and the side fences 13a and 13b. Further, since it is possible to prevent objects and the like from being caught by the mattress regulating portion 64a, for example, as compared with the case where the objects are prevented from being caught by increasing the height of the mattress placement surface of the waist bottom 22. Further, it is possible to prevent an object or the like from being caught in a state where the height of the mattress mounting surface is arranged below the side rails 13a and 13b. As a result, the mattress placement surface can be lowered to facilitate the so-called low flooring.

The bottom hinge 64d is disposed above the mattress placement surface of the back bottom 21. For this reason, compared with the case where the back bottom 21 rotates around the center of rotation arranged at the position equal to or below the mattress placement surface, the back at the time of raising the back. The mattress placement surface of the bottom 21 can be rotated upward while being moved toward the head side H. Thereby, it can suppress that the back bottom 21 presses a user's body at the time of back raising.
Furthermore, since the side member 64 has the bottom hinge 64d to realize the function of suppressing the above-described compression, this function can be realized with a simple configuration while suppressing an increase in parts.

  In addition, since the back bottom 21 has a plurality of vent holes 21a, it is possible to improve the air permeability of the bed apparatus 10 and to make it comfortable to sleep, and the back bottom 21 is a belt receiving portion that regulates the position of the belt. Since it has 21b, these functions can be realized with a simple configuration.

  Further, since the side member 64 has the bottom hinge 64e which is the rotation center of the knee bottom 24, the function as the rotation center of the knee bottom 24 is realized while suppressing an increase in parts, and the slide attached to the foot bottom 25. Since the moving member 28 has a function of sliding between the foot bottom 25 and the second vertical member 37 and a function of regulating the position of the mattress by the mattress regulating part 28a, these increases while suppressing an increase in parts. Function can be realized.

  The technical scope of the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present invention.

  For example, the board 14 and the option 15 may be omitted.

Moreover, in the said embodiment, although the waist bottom 22 was made into the multifunctional bottom and the side material 64 which has various functions was arrange | positioned at the both sides of the waist bottom 22, this invention is not limited to this. For example, the side members 64 may be disposed on both sides of the back bottom 21, the knee bottom 24, or the foot bottom 25 in the left-right direction, and the bottoms other than the waist bottom 22 may be multifunctional bottoms.
Alternatively, the side member 64 may be disposed only on one side of the waist bottom 22 in the left-right direction.

In the above-described embodiment, a 4ACT (4-motor) gatch bed is adopted, in which both the back bottom 21 and the leg bottom 23 are movable bottoms that rotate, and that has an elevating mechanism 33 that elevates and tilts the bed 11. The present invention is not limited to this. For example, 3ACT (3 motor) without tilting mechanism, 2ACT (2 motor) without lifting mechanism 33, 1ACT (1 motor) where only one of back bottom 21 or leg bottom 23 rotates is adopted. It is also possible to do. In the case of a 1ACT (one motor) gatch bed, the bed apparatus 10 can be preferentially mounted with a back raising function using the back bottom 21 as a movable bottom. That is, the present invention can employ a configuration in which at least one of the back bottom 21 and the leg bottom 23 is a movable bottom, and at least the back bottom 21 of the back bottom 21 and the leg bottom 23 is movable bottom. The configuration described above can be adopted.

For this reason, the same code | symbol is attached | subjected to the same structure, the description is abbreviate | omitted, and only a different point is demonstrated.
The bed apparatus 10 according to the present embodiment is different from the above-described embodiment in that X-ray imaging can be easily performed with a user on the bed apparatus 10.

As shown in FIG. 10, the back bottom 21 of the present embodiment includes a bottom-side scale portion 21c. Further, the back bottom 21 of the present embodiment is formed of a material that can transmit X-rays. A pair of bottom scale portions 21 c are arranged at both left and right end portions on the upper surface of the back bottom 21. The scale of the bottom scale part 21c displays, for example, the position of the user's lungs in the front-rear direction.
FIG. 12 is a perspective view showing a state in which a cassette holder 70 described later is pulled out, and the back bottom 21 is indicated by a two-dot chain line. As shown in FIG. 12, the back bottom 21 of the present embodiment includes an abutting portion 21d and a pair of holder holding portions 21e. The abutting portion 21d and the pair of holder holding portions 21e are disposed on the lower surface side of the back bottom 21. The end of the foot side F of the cassette holder 70 is abutted against the abutting part 21d. Thereby, the abutting portion 21d determines the position of the cassette holder 70 in the front-rear direction. Each of the pair of holder holding portions 21e is formed in a rail shape bent into an L shape. The pair of holder holding portions 21 e can hold the cassette holder 70. The pair of holder support portions 21e hold the cassette holder 70 so as to be slidable and detachable in the front-rear direction.
The back bottom 21 shown in FIG. 10 may include a plurality of vent holes 21a shown in FIG.

  As shown in FIGS. 10 and 12, a cassette holder 70 is disposed on the lower surface side of the back bottom 21. The cassette holder 70 is held by the pair of holder holding portions 21e. A cassette for X-ray imaging (not shown) can be accommodated in the cassette holder 70. As shown in FIG. 11, the cassette holder 70 includes a handle portion 71, a holder main body 72, a positioning mechanism 76, and a holder-side scale portion 75. The holder main body 72 is formed in a rectangular shape that is long in the front-rear direction in plan view. A cassette (not shown) can be placed in the holder main body 72. The handle portion 71 is disposed at the end portion on the head side H of the holder main body 72. The positioning mechanism 76 determines the position of the cassette accommodated in the cassette holder 70 within a range corresponding to the holder-side scale portion 76. The positioning mechanism 76 includes a pair of positioning portions 73 and a positioning bar 74. Each of the pair of positioning portions 73 has positioning holes 73a to 73e. The positioning holes 73a to 73e are each connected to a long hole 73f that is long in the front-rear direction. The end of the positioning bar 74 is inserted through the positioning holes 73a to 73e. The position of the positioning bar 74 in the front-rear direction is determined depending on which of the positioning holes 73a to 73e the end of the positioning bar 74 is inserted into. That is, the positioning unit 73 can determine that the position of the positioning bar 74 in the front-rear direction can be switched. The positioning bar 74 serves as a reference for determining the position of the cassette in the front-rear direction when a cassette (not shown) is accommodated in the cassette holder 70. The position of the positioning bar 74 in the left-right direction is regulated by the tip of the end of the positioning bar 74 coming into contact with the holder holding portion 21e in the left-right direction. The holder side scale part 75 has a scale corresponding to the position of the positioning holes 73a to 73e in the front-rear direction. The position of each scale of the holder side scale part 75 corresponds to the position of each scale of the bottom side scale part 21c.

Next, the operation of each part in this embodiment will be described.
For example, when X-ray imaging of the user's lungs is performed, the user is placed on the bed apparatus 10 and the position of the user's lungs in the front-rear direction is read by the bottom scale portion 21c. The result read by the bottom scale portion 21 c is reflected in the position of the positioning bar 74 of the cassette holder 70. For example, when the position of the user's lung at the bottom scale portion 21c is “3”, the end of the positioning bar 74 is inserted into the positioning hole 73c. As a result, the position of the positioning bar 74 is determined as the position “3” in the holder-side scale portion 75. Next, the cassette is placed on the holder main body 72 and abutted against the positioning bar 74. Then, the cassette holder 70 is slid to the foot side F on the holder holding portion 21 e, and the end of the foot side F of the cassette holder 70 is abutted against the abutting portion 21 d of the back bottom 21. Thereby, the relative position of the cassette holder 70 and the back bottom 21 is determined.
As described above, the position in the front-rear direction of the cassette accommodated in the cassette holder 70 matches the position in the front-rear direction of the user's lung, and X-ray imaging can be easily performed.

In addition, although the said embodiment demonstrated the case where a user's lung was radiographed, this invention is not limited to this. For example, a cassette holder 70 having a bottom scale portion 21c on the waist bottom 22 or the leg bottom 23 and including a holder scale portion 75 corresponding to the bottom scale portion 21c may be employed. In this case, it is possible to easily perform X-ray imaging of parts such as the user's waist and legs.
Moreover, the scale of the bottom side scale part 21c may display the position of the user's body in the left-right direction. In this case, positioning holes 73a to 73e and a positioning bar 74 that determine the position of the cassette in the left-right direction may be used.
Moreover, although the positioning mechanism 76 of the said embodiment determined the position of the cassette accommodated in the cassette holder 70 by the positioning holes 73a-73e and the positioning bar 74, this invention is not limited to this. For example, a positioning mechanism 76 that determines the position of the cassette in the cassette holder 70 by providing a positioning wall that can slide in the cassette holder 70 and abutting the cassette against the positioning wall may be employed. Or you may employ | adopt the positioning mechanism 76 which determines the position of the cassette in the cassette holder 70 by inserting the pin which protrudes from a cassette in either of the positioning holes 73a-73e.
Moreover, in the said embodiment, although the cassette holder 70 was arrange | positioned in the center part in the left-right direction of the back bottom 21, this invention is not limited to this. For example, the cassette holder 70 may be arranged so as to be biased to the left or right with respect to the back bottom 21. In this case, the back bottom 21 may be provided with a display unit that displays the position of the cassette holder 70 in the left-right direction.

  In addition, it is possible to appropriately replace the constituent elements in the embodiment with well-known constituent elements without departing from the spirit of the present invention, and the above-described modified examples may be appropriately combined.
