Description

  The present invention relates to a bed, and more particularly to a bed from which a side fence can be removed.

  In recent years, electric beds used in hospitals and homes have become widespread. The electric bed includes a bottom (floor plate body) that supports a human body and a drive mechanism that changes the posture of the bottom. The bottom whose posture can be changed includes a back bottom, a waist bottom, a knee bottom, and a foot bottom that are rotatably connected.

  Furthermore, the electric bed has an insertion port on the side surface of the bed from which the side rail can be attached and detached. Side rails include types such as side rails and bed grips (or assistance bars). A side rail is a fence for preventing a person sleeping in a bed from falling or a bedding from falling. The bed grip is a fence for assisting operations such as getting up and getting up from the bed.

  The insertion port to which the side fence can be attached is usually at a position protruding slightly from the side edge of the bottom. In a state where the side fence is removed, there is a possibility that the insertion port and a person or an object come into contact. For example, when a person moves from a wheelchair to a bed, there is a problem that the insertion port is obstructive even though he wants to bring the wheelchair as close to the bed as possible.

  For this reason, Patent Documents 1 to 3 each propose a bed in which the insertion port can be stored inside the side edge of the bottom.

(Embodiment 1)
FIG. 1 is a perspective view illustrating a configuration example of a bed according to Embodiment 1. FIG. FIG. 2 is a top view illustrating a configuration example of the bed. The bed according to FIGS. 1 and 2 is an electric bed used in hospitals, homes, and the like, and a side fence having two columns can be attached and detached. This bed includes a frame 11, a bottom 20, and four side fence support portions 30 as main portions. In addition to this, the bed includes a head side board, a foot side board, an electric motor, an operation remote controller, and the like.

  The frame 11 is a frame that serves as a bed base. Side fence support portions 30 are attached to four locations of the frame body 11.

  The bottom 20 has a plurality of parts that are sequentially connected by a hinge or the like, that is, a back bottom 21, a waist bottom 22, a knee bottom 23, and a foot bottom 24.

  Each of the side fence support portions 30 can be attached and detached with a side fence having two columns. That is, each of the side fence support part 30 has the 1st and 2nd support members 31 and 32 with the insertion port into which the support | pillar of a side fence is inserted.

  The first support member 31 is rotatably attached to the frame body 11 and has a first insertion hole 37 that receives one of the two columns of the side fence.

  The second support member 32 is rotatably attached to the frame body 11 and has a second insertion hole 38 that receives the other of the two columns of the side fence.

  Each of the first and second support members 31 and 32 has a first position inside the side edge of the bed and a second position where the insertion holes 37 and 38 are exposed outside the side edge of the bed. It is possible to rotate between the two. That is, each of the first and second support members 31 and 32 protrudes outward from the side edge of the bed in the state where it is housed inside the side edge of the bed in the first position. The two states, ie, the state (non-storage state), are taken alternatively. Moreover, the first and second support members 31 and 32 rotate in conjunction with one rotation.

  Here, the side fence will be described.

  FIG. 3 is a diagram illustrating a configuration example of a side fence. In the same figure, the side fence 40 has support columns 41 and 42. The support columns 41 and 42 are inserted into the first and second support members 31 and 32 and function as a bed side fence. In general, there are a plurality of types of side rails such as side rails and bed grips (or assistance bars). The side rail mainly refers to a fence for preventing a person sleeping in the bed from falling or a bedding from falling. The bed grip mainly refers to a fence for assisting operations such as getting up on the bed and getting up from the bed. The bed of FIGS. 1 and 2 can be equipped with four side rails. As for each side fence support part 30, a side fence can be attached or detached, and it is also possible to replace | exchange for another side fence. Moreover, the front-end | tip part of the support | pillar 41 and the support | pillar 42 is a cap type which puts a front-end | tip member on a support | pillar main body in the figure.

  Next, the detailed structure of the side fence support part 30 which has the 1st and 2nd support members 31 and 32 which rotate in conjunction is demonstrated.

  FIG. 4A is a perspective view illustrating a detailed configuration example of the side fence support portion 30 in the non-storing state according to the first embodiment. FIG. 4B is a perspective view showing a detailed configuration example of the side fence support portion 30 in the housed state. The non-storing state refers to a state where the first and second support members 31, 32 are in the first position. The stowed state refers to a state where the first and second support members 31 and 32 are in the second position.

  In FIG. 4A and FIG. 4B, the side fence support portion 30 includes a first support member 31, a second support member 32, a connecting rod 33, a first bracket 35, and a second bracket 36.

  The first support member 31 has a first insertion hole 37 for receiving one of the two columns of the side fence 40 and is attached to the first bracket 35 so as to be rotatable about the connecting rod 33 as an axis. It is done.

  The second support member 32 has a second insertion hole 38 that receives the other of the two columns of the side fence 40, and is attached to the second bracket 36 so as to be rotatable about the connecting rod 33 as an axis. It is done.

  The connecting rod 33 rotates the other of the first and second support members 31, 32 in conjunction with the rotation of one of the first and second support members 31, 32. 4A and 4B, the connecting rod 33 is fixed to each of the first and second support members 31 and 32 and functions as a rotation shaft.

  The first bracket 35 rotatably holds the first support member 31 and is fixed to the frame body 11. Further, the first bracket 35 has a holding portion 34 that holds a detachable fixing member for fixing the first support member 31 at the second position. 4A and 4B is a pin hole for holding a pin as a fixing member. This pin hole is formed in both side plates of the first bracket 35. Further, the fixing member 34a may be a pin as shown in FIG. 5, for example. In the non-storage state shown in FIG. 4A, the first support member 31 is prevented from rotating by holding the fixing member 34a (pin) in the holding portion 34 (pin hole). That is, it is possible to prevent the upper end of the side fence 40 from wobbling in the lateral direction of the bed with the side fence 40 attached.

  The second bracket 36 rotatably holds the second support member 32 and is fixed to the frame body 11. Furthermore, the second bracket 36 has a holding portion 34 that holds a detachable fixing member for fixing the second support member 32 in the second position. The holding portion 34 of the second bracket 36 is the same as the holding portion 34 of the first bracket 35.

  4A and 4B show an example in which the holding portion 34 is formed on both the first bracket 35 and the second bracket 36, the holding portion 34 has the first bracket 35 and the second bracket. It may be formed on any one of 36.

  Moreover, the side fence support part 30 may be provided with the other holding part which hold | maintains the pin shown in FIG. 5 secondarily in the accommodation state shown to FIG. 4B. For example, the other holding portion may be a cylindrical body fixed to the first bracket 35 or the second bracket 36 and configured to hold the pin.

  According to the bed according to the first embodiment configured as described above, if one of the first support member 31 and the second support member 32 is rotated, the other is also rotated by the rotation of the connecting rod 33. . Therefore, a user such as a caregiver can very easily perform the operation of storing and taking out the first support member 31 and the second support member 32. For example, the storing operation and the extracting operation can be facilitated with one hand. In other words, the non-storage state shown in FIG. 4A and the storage state shown in FIG. 4B in the first support member 31 and the second support member 32 can be easily changed with one hand.

  Moreover, the wobbling of the side fence 40 can be suppressed by attaching the pin to the pin hole in the non-storage state.

  As described above, the bed according to the first embodiment is attached to the frame 11 serving as a bed base to which a side fence having two support columns can be attached, and the frame 11 so as to be rotatable. A first support member 31 having a first insertion hole 37 that receives one of the columns, and a second insertion hole 38 that is rotatably attached to the frame 11 and receives the other of the two columns. A second support member 32 and a connecting rod 33 that connects the first and second support members 31 and 32 to each other are provided. Each of the first and second support members 31 and 32 exposes the first position inside the side edge of the bed and the first and second insertion holes 37 and 38 outside the side edge of the bed. It rotates between the second position to be made. The connecting rod 33 rotates the other of the first and second support members 31, 32 in conjunction with the rotation of one of the first and second support members 31, 32.

  According to this, the connecting rod 33 rotates the other of the first and second support members 31, 32 in conjunction with the rotation of one of the first and second support members 31, 32. Therefore, when a user such as a caregiver rotates only one of the first and second support members 31 and 32, both the first and second support members 31 and 32 are in the stored state (that is, the first support member 31 and 32). 1 position) or non-storage state (that is, the second position) can be changed simultaneously. That is, it is possible to easily take out and store the insertion opening of the side fence. For example, the outlet can be taken out and stored with one hand.

  Here, each of the first and second support members 31, 32 may be fixed to the connecting rod 33 and rotated about the connecting rod 33.

  According to this, the storage state and the non-storage state are easily changed by rotating only one of the first and second support members 31 and 32 in the vertical direction (or vertical direction). be able to.

  Here, the bed holds the first support member 31 rotatably, holds the first bracket 35 fixed to the frame body 11 and the second support member 32 rotatably, and the frame body. 11 and a second bracket 36, and at least one of the first and second brackets 35, 36 is detachable to fix the first or second support member 31, 32 in the second position. You may have the holding | maintenance part 34 which hold | maintains the fixing member 34a.

  According to this, the 1st and 2nd support members 31 and 32 can be attached to the frame 11 by the 1st and 2nd brackets 35 and 36 so that rotation is possible.

  Here, the fixing member 34 a may be a pin, and the holding portion 34 may be a pin insertion hole provided in at least one of the first and second brackets 35 and 36.

  According to this, the wobbling of the side fence can be reduced while the side fence is attached, and the side fence can be stabilized.

(Embodiment 2)
Then, the side fence support part 30 which concerns on Embodiment 2 is demonstrated. In the first embodiment, the example in which the first and second support members 31 and 32 rotate vertically (that is, the example in which the rotation shaft is horizontal) has been described. (In other words, an example in which the rotation axis is vertical) will be described. The schematic configuration of the bed according to the present embodiment is the same as that shown in FIGS. Hereinafter, different points will be mainly described.

  FIG. 6A is a perspective view illustrating a detailed configuration example of the side fence support portion 30 at the time of non-storage according to the second embodiment. FIG. 6B is a perspective view illustrating a detailed configuration example of the side fence support portion 30 at the time of storage according to the second embodiment.

  6A and 6B includes a first support member 31, a second support member 32, a connecting rod 33, a first bracket 35, and a second bracket 36.

  The first support member 31 has a first insertion hole 37 that receives one of the two columns of the side fence 40 and rotates in parallel (that is, laterally) with the upper surface of the bed.

  The second support member 32 has a second insertion hole 38 that receives the other of the two columns of the side fence 40, and rotates in parallel (that is, laterally) with the upper surface of the bed.

  The connecting rod 33 rotates the other of the first and second support members 31, 32 in conjunction with the rotation of one of the first and second support members 31, 32. The connecting rod 33 is connected to the first and second support members 31 and 32 so as to rotate the first and second support members 31 and 32 in directions opposite to each other.

  The first bracket 35 is fixed to the frame 11 and holds the first support member 31 in a rotatable manner. In order to hold the first support member 31 rotatably, the first bracket 35 has a shaft bar 39a perpendicular to the upper surface of the bed. The shaft bar 39a is fitted into a bearing (for example, a through hole) of the first support member 31.

  The 2nd bracket 36 is fixed to the frame 11, and hold | maintains the 2nd support member 32 so that rotation is possible. In order to hold | maintain the 2nd support member 32 so that rotation is possible, the 2nd bracket 36 has the axial bar 39b perpendicular | vertical to the upper surface of a bed. The shaft bar 39b is fitted into a bearing (for example, a through hole) of the first support member 31.

  Next, a more detailed configuration example of the side fence support portion will be described with respect to the connecting rod 33 that rotates the first and second support members 31 and 32 in opposite directions.

  FIGS. 7A and 7B are a top view and a front view showing a detailed configuration example of the side fence support portion 30 when not housed according to the second embodiment. FIG. 8 is a top view and a front view showing a detailed configuration example of the side fence support portion 30 at the time of storage according to the second embodiment. 7 and 8 are the same as FIGS. 6A and 6B, and therefore, here, a description will be given focusing on a connection mechanism using the connection rod 33 that is not sufficiently represented in FIGS. 6A and 6B.

  The first support member 31 includes a support body 31a and a shaft body 31b. The support body 31 a has a first insertion hole 37. The shaft body 31b is fixed to the support body 31a and is rotatably connected to one end of the connecting rod 33 at a position separated from the support body 31a by a predetermined distance or more. Here, the predetermined distance is a distance sufficiently larger than a human finger (for example, 3 cm or more), and the first support member 31 and the connecting rod 33 are provided so as not to pinch the human finger. 7 and 8, the distance from the shaft body 31b to the frame body 11 is smaller than the distance from the shaft bar 39a to the frame body 11. In other words, the shaft body 31b is closer to the bed than the shaft bar 39a.

  The second support member 32 includes a support body 32a and a shaft body 32b. The support main body 32 a has a second insertion hole 38. The shaft body 32b is fixed to the support body 32a and is rotatably connected to the other end of the connecting rod 33 at a predetermined distance from the support body 32a. Here, the predetermined distance is as described above. Further, the distance from the shaft body 32b to the frame body 11 is larger than the distance from the shaft bar 39b to the frame body 11. In other words, the shaft body 32b is located farther from the bed than the shaft body 31b. Thereby, the 1st supporting member 31 and the 2nd supporting member 32 can be rotated in a reverse direction.

  One end of the connecting rod 33 is connected to the shaft body 31b, and the other end is connected to the shaft body 32b. The shaft body 31b and the shaft body 32b are positioned so as to sandwich the straight line with respect to the straight line passing through the shaft rods 39a and 39b of the first and second support members 31. With such a coupling mechanism, the coupling rod 33 can rotate the first and second support members 31 and 32 in directions opposite to each other.

  As described above, according to the bed in the present embodiment, if one of the first support member 31 and the second support member 32 is rotated, the other is also rotated by the connecting rod 33. Therefore, a user such as a caregiver can very easily perform the operation of storing and taking out the first support member 31 and the second support member 32. For example, the storing operation and the extracting operation can be facilitated with one hand. In other words, the non-storage state shown in FIG. 6A and the storage state shown in FIG. 6B in the first support member 31 and the second support member 32 can be easily changed with one hand.

  Further, if the first and second support members 31 and 32 are rotated in the same direction, the side rail 40 can be rotated even when the side rail 40 is attached, and the side rail 40 can swing in the longitudinal direction of the bed. Become. However, in the bed according to the second embodiment, the first and second support members 31 and 32 rotate in opposite directions, so that the side fence 40 is in the longitudinal direction of the bed with the side fence 40 attached. The mounting position can be prevented from swinging.

  As described above, in the bed according to the second embodiment, each of the first and second support members 31 and 32 rotates in parallel with the upper surface of the bed, and the connecting rod 33 supports the first and second supports. The members 31 and 32 are rotated in the opposite direction.

  According to this, the non-storage state and the storage state in the first support member 31 and the second support member 32 can be easily changed with one hand.

  Here, the bed is held by a first bracket 35 having a shaft bar 39 a held by the bearing of the first support member 31 and fixed to the frame body 11, and by a bearing of the second support member 32. The first support member 31 is attached to the shaft rod 39a of the first support member 31 and has a first insertion plug. A first support body 31a having a hole 37 and a first support body 31a which is fixed to the first support body 31a and connects one end of the connection bar 33 to a position closer to the inside of the bed than the shaft bar 39a of the first support body 31a. The second support member 32 is attached to the shaft bar 39b of the second support member 32 and has a second insertion hole 38, and the second support member 32 has a first shaft body 31b. 2 is fixed to the support body 32a of the second main body 32 and is higher than the shaft bar 39b of the second main body 32. It may have a second shaft 32b for connecting the other end of the connecting rod 33 to the outboard position of de.

  According to this, the connection mechanism in which the first support member 31 and the second support member 32 rotate in opposite directions can be realized with a simple configuration.

  Here, the distance between the connecting rod 33 and the first support body 31a and the distance between the connecting rod 33 and the second support body 32a may be separated by a predetermined distance or more.

  According to this, when a user such as a caregiver rotates one of the first and second support members 31, 32, the first and second support members 31, 32 and the connecting rod 33 are human. You can avoid pinching your fingers.

  Although the bed according to the present invention has been described based on the embodiment, the present invention is not limited to the embodiment. Without departing from the gist of the present invention, various modifications conceived by those skilled in the art have been made in the present embodiment, and other forms constructed by arbitrarily combining some components in the embodiments and modifications are also possible. Are included within the scope of the present invention.

  For example, the bed in each of the above embodiments may be an electric bed or may not be an electric bed.

  Moreover, although the support | pillars 41 and 42 of the side fence 40 are a cap type in FIG. 3, they may not be a cap type. For example, the structure which inserts a support | pillar main body directly in the insertion holes 37 and 38 may be sufficient.

  Moreover, although the support | pillars 41 and 42 showed the example which is a cylinder, a prism may be sufficient. In this case, the horizontal cross-sectional shape of the first and second insertion holes 37, 38 of the side fence support part 30 may be the same shape as the horizontal cross-section with the support columns 41, 42, or a different shape. Also good.

  4A and 4B may be circular or polygonal in cross section.

  Furthermore, although the example in which the holding portion 34 and the fixing member 34a in FIGS. 4A and 4B are pin holes and pins has been described, the present invention is not limited thereto. For example, the fixing member 34a is a plate-shaped small piece, and the holding portion 34 is a hinge attached to the upper end of the first or second bracket 35 or 36, and the small piece is turned inside the bracket. A hinge that can be freely attached may be used.

  In addition, the connecting rod 33 in FIG. 6A and FIG. 6B only needs to have connecting holes connected to the shaft body 31b and the shaft body 32b at both ends. Also good.

  6A and 6B, the shaft body 31b and the shaft body 32b are provided at a position about 45 degrees from the shaft rod 39a or the shaft rod 39b with respect to the straight line passing through the shaft rod 39a and the shaft rod 39b. For example, the position may be about 90 degrees, and may be anywhere as long as it is provided at a position sandwiching the straight line. This is because the first and second support members 31 and 32 can be rotated in opposite directions if they are provided at positions sandwiching the straight line.

  Moreover, although FIG. 2 demonstrated the example in which the side fence support part 30 was installed in four places of the side edge of a bed, you may install in the other edge | side of a bed.
