Description

  The present invention relates to a foot bottom support mechanism that supports a foot bottom of a bed apparatus.

  There is known a bed apparatus including a mechanism portion that performs a back raising operation and a knee raising operation (for example, Patent Document 1). In the back raising operation, the back bottom mounted on the upper frame is operated to raise the back of the user in contact with the back bottom so that the user is sitting from a lying state (a supine state). . In the knee raising operation, the knee of the user is raised by operating the knee bottom placed on the upper frame.

  Such a bed apparatus is used at home by a user who is physically disabled, for example. The user can make his / her preferred posture by causing the bed apparatus to perform a back raising operation or a knee raising operation.

  In addition, the caregiver can easily care for the user by causing the bed apparatus to perform a back raising operation or a knee raising operation. As described above, the bed apparatus can assist the operation of the user who is used at home, and can also care for the caregiver who cares for the user.

  One end of the foot bottom is rotatably connected to the knee bottom. A support mechanism (foot bottom support mechanism) is provided below the other end of the foot bottom, and the foot bottom support mechanism is positioned at the other end of the foot bottom when the knee-lifting operation is performed, that is, the user's foot. The previous position can be adjusted to a first position (high position) or a second position (low position) lower than the first position (for example, Patent Document 2).

  With the foot bottom support mechanism of the conventional bed apparatus, when the caregiver adjusts the position of the user's foot to a low position, the end of the foot support stay is set to the lower step of the foot support stay support. By arranging, the position of the user's feet can be kept at a low position no matter how many times the transition from the knee raising operation to the knee lowering operation is performed. In addition, when the caregiver adjusts the position of the user's foot to a high position, by placing the end of the foot support stay at the engaging portion of the support for the foot support stay, The position of the user's toes can be kept high no matter how many times the transition to the knee lowering operation is performed.

  However, in the foot bottom support mechanism of the conventional bed apparatus, there are two places where the end of the foot support stay is arranged on the support part for the foot support stay. There is a possibility that it is difficult to understand how to do. In other words, the caregiver places the end of the foot support stay on the foot support stay, regardless of whether the user's foot position is adjusted to a low position or the user's foot position is adjusted to a high position. The care supporter may find it difficult to understand how to place the foot support stays.

  Further, in the foot support stay support portion, the lower step portion is positioned above the engagement portion. For this reason, when the caregiver adjusts the position of the user's foot to the “low position”, the end of the foot support stay is placed on the lower step on the “upper” of the foot support stay support. Will be placed. On the other hand, when the position of the user's foot tip is adjusted to the “high position”, the end portion of the foot tip support stay is disposed in the engagement portion at the “lower stage” of the foot tip support stay support portion (engagement). Will be). Therefore, the caregiver is in two states in which the foot support stay is arranged (specifically, the end of the foot support stay is arranged in the upper stage or the lower stage with respect to the adjustment (high / low) of the user's toes. Two states) must be understood. For this reason, there is a possibility that a caregiver who cares for the user may be burdened by machine operation.

  The present invention has been made in view of the above points, and when the caregiver adjusts the position of the user's toes, the arrangement of the foot support stays becomes easier to understand than before, and the caregiver An object of the present invention is to provide a foot bottom support mechanism for a bed apparatus that can reduce the burden on the bed as compared with the prior art.

  The foot bottom support mechanism of the bed apparatus according to the present invention includes a bed frame, a knee bottom supported at one end of the bed frame so as to be capable of rotating up and down, and one end rotated at the other end of the knee bottom. In a foot bottom support mechanism of a bed apparatus including a foot bottom that is operatively coupled, a foot tip support stay that is pivotally coupled to the lower side of the other end of the foot bottom, and is provided on the bed frame, A foot support stay support for movably supporting the tip of the foot support stay when the other end of the foot bottom is adjusted to the first position; and a lower surface of the foot bottom. A foot support stay fixing member for fixing the foot support stay to the foot bottom when the other end of the foot bottom is adjusted to a second position lower than the first position. It is characterized by that.

  In the foot bottom support mechanism of the bed apparatus of the present invention, the foot tip support stay fixing member is formed with a groove portion to which the foot tip support stay can be attached and detached, and the other end portion of the foot bottom is adjusted to the second position. The foot support stay is attached to the groove portion of the foot support stay fixing member, and when the other end of the foot bottom is adjusted from the second position to the first position, The foot support stay is removed from the groove portion of the foot support support fixing member, and the tip of the foot support support is movably supported by the foot support stay support. .

  In the foot bottom support mechanism of the bed apparatus of the present invention, when the mattress is provided on the upper surface of the bottom, the foot bottom is prevented from shifting in the length direction of the mattress above the other end of the foot bottom. A footrest mattress stopper including a mattress displacement suppression portion for supporting the mattress displacement suppression portion on the lower surface of the foot bottom, and a lower surface of the foot bottom. Is provided with a mattress stopper fixing member for a foot for fixing the mattress displacement suppressing portion support of the mattress stopper for the foot to the bottom of the foot, and the mattress stopper fixing member for the foot includes A groove portion on which the mattress displacement suppressing portion support of the mattress stop portion for the foot tip is detachable is formed, and the foot support stay fixing member is the mattress stop for the foot tip. It is the same member as the constant member, characterized in that.

  In the foot bottom support mechanism of the bed apparatus of the present invention, the foot tip support stay support portion engages the tip end portion of the foot tip support stay when the other end portion of the foot bottom is adjusted to the first position. It is characterized by having an engaging portion for joining.

  According to the present invention, when the caregiver adjusts the position of the user's foot to a low position, by fixing the foot support stay to the foot support support fixing member on the lower surface of the foot bottom, The position of the user's toes can be kept low no matter how many times the transition to the knee lowering operation is performed. In addition, when the caregiver adjusts the position of the user's toes to a high position, the support for the toe support stays is supported by the support for the toe support stays, so that the transition from the knee raising operation to the knee lowering operation is performed. No matter how many times it is done, the position of the user's toes can be kept high.

  Furthermore, according to the present invention, the caregiver only needs to arrange the foottip support stay on the support portion for the foottip support stay only when adjusting the position of the user's foottip to a high position. Is easier to understand than the conventional way of arranging the foot support stays.

  The reason is that the foot support stay support portion is not provided with the low step portion in the conventional bed apparatus. Instead, a foot support stay fixing member for fixing the foot support stay is provided on the lower surface of the foot bottom. For this reason, the caregiver may fix the foot support stay to the foot support stay fixing member on the lower surface of the foot bottom when the position of the user's foot tip is adjusted to the “low position”. On the other hand, when adjusting the position of the user's foot to the “high position”, remove the foot support stay from the foot support stay fixing member and place the foot support stay on the support portion for the foot support stay. That's fine.

  That is, the caregiver arranges the foot support stay on the support portion for the foot support stay only when the position of the user's foot is adjusted to the “high position”. Therefore, the caregiver is in a state in which the foot support stay is arranged with respect to the user's foot adjustment (high or low) (conventionally, the end of the foot support stay is arranged in the upper stage or the lower stage). There is no need to understand (two states). For this reason, the burden by a machine operation is not given with respect to the caregiver who cares a user.

  As described above, according to the present invention, when the caregiver adjusts the position of the user's toes, the arrangement of the toe support stays becomes easier to understand than before, and the caregiver's burden is reduced more than before. Can be reduced.

  Next, the operation of the foot bottom support mechanism of the bed apparatus 1 according to the present invention will be described.

  First, when the caregiver adjusts the position of the user's toes to a low position and the user or the caregiver performs the knee lifting operation on the bed apparatus, 6 and FIG.

  As shown in FIG. 6, one of the support stays 107 of the foot support stay 170 is attached to the groove 192 of the foot support stay fixing member 190, and the knee bottom 102 is turned up. It is in a state. In this state, the support stay portion 107 does not support the other end portion of the foot bottom 106, so that one end portion of the foot bottom 106 is raised together with the knee bottom 102, but the other end portion is positioned on the bed frame 101. Yes. That is, the position of the user's foot is in the low position.

  When the knee bottom 102 is pivoted and lowered from this state, the other end of the foot bottom 106 moves in the direction of the foot while being supported on the bed frame 101.

  It is assumed that the knee bottom 102 is further rotated and lowered from this state, and the knee bottom 102 and the foot bottom 106 are in a horizontal state. When the knee bottom 102 is rotated and raised from this state (the knee bottom 102 and the foot bottom 106 are in a horizontal state), one end of the foot bottom 106 follows the reverse of the rotation and descends. The other end is located on the bed frame 101. That is, the position of the user's foot is again in the low position.

  Next, a case where the caregiver adjusts the position of the user's foot from the low position to the high position will be described with reference to FIGS. 8 and 9.

  As shown in FIG. 8, the caregiver lifts the other end of the foot bottom 106. Thereafter, the caregiver releases the fixation of the foot support stay 170 by the foot support stay fixing member 190. Specifically, the caregiver removes the support stay 107 of the foot support stay 170 from the groove 192 of the foot support support fixing member 190 on the lower surface of the foot bottom 106.

  In this state, when the foot bottom 106 is lowered, the tip 109 of the support stay 107 reaches the inclined surface 114 formed in the engaging portion 113 and is further lowered as shown in FIG. In this case, the engagement portion 113 is brought into contact with the wall constituting the engagement portion 113 to be in an engaged state.

  Next, when the caregiver adjusts the position of the user's foot to a high position and the user or the caregiver performs the knee lifting operation on the bed apparatus, the knee lowering operation is performed. This will be described with reference to FIGS.

  As shown in FIG. 9, the tip 109 of the support stay 107 is located at the engaging portion 113, and the knee bottom 102 is turned up. In this state, the tip 109 of the support stay 107 is positioned in the direction of the head of the engaging portion 113, and the support stay 107 supports the other end of the foot bottom 106. The part rises with the knee bottom 102, and the other end is located above the bed frame 101. That is, the position of the user's foot is in a high position by the support stay 107.

  When the knee bottom 102 is pivoted and lowered from this state, the other end of the foot bottom 106 moves in the direction of the foot while being supported by the support stay 107, and as shown in FIG. 102 and the foot bottom 106 are in a horizontal state.

  In this state, the tip 109 of the support stay 107 is positioned at the engaging portion 113. However, since the support stay 107 supports the other end of the foot bottom 106, this state (with the knee bottom 102 and When the knee bottom 102 is rotated and raised from a state where the foot bottom 106 is in a horizontal state, one end of the foot bottom 106 rises together with the knee bottom 102 and the other end is positioned above the bed frame 101. That is, the position of the user's foot is again set to the high position by the support stay portion 107.

  As described above, in the foot bottom support mechanism of the bed apparatus 1 according to the present invention, when the caregiver adjusts the position of the user's foot tip to the low position, the foot tip support stay 170 is attached to the bottom surface of the foot bottom 106. By fixing to the tip support stay fixing member 190 (specifically, by attaching the support stay portion 107 of the foot tip support stay 170 to the groove portion 192 of the foot tip support stay fixing member 190 on the lower surface of the foot bottom 106) The position of the user's toes can be kept at a low position no matter how many times the transition from the knee raising operation to the knee lowering operation is performed. Further, when the caregiver adjusts the position of the user's foot to a high position, the foot support stay 170 is supported by the foot support stay support 111 (specifically, the foot support stay 170). No matter how many times the transition from the knee-raising operation to the knee-lowering operation is performed by engaging the distal end portion 109 of the 170 support stay portion 107 with the engagement portion 113 of the foot support stay support portion 111) The position of the person's toes can be kept high.

  Furthermore, in the foot bottom support mechanism of the bed apparatus 1 according to the present invention, the caregiver can change the foot support stay 170 to the foot support support support 111 only when the position of the user's foot is adjusted to a high position. Therefore, it is easier for caregivers to understand how to place the foot support stays 170 than in the past.

  The reason is that the foot support stay supporting portion 111 is not provided with the low step portion 1016 in the conventional bed apparatus. Instead, a foot support stay fixing member 190 for fixing the foot support stay 170 is provided on the lower surface of the foot bottom 106. Therefore, when the caregiver adjusts the position of the user's foot to the “low position”, the caregiver should fix the foot support stay 170 to the foot support stay fixing member 190 on the lower surface of the foot bottom 106. Specifically, the support stay 107 of the foot support stay 170 may be attached to the groove 192 of the foot support stay fixing member 190 on the lower surface of the foot bottom 106. On the other hand, when adjusting the position of the user's toes to the “high position”, the toe support stays 170 are removed from the toe support stay fixing members 190 and the toe support stays 170 are attached to the support parts for the toe support stays. 111 (specifically, the support stay 107 of the foot support stay 170 is removed from the groove 192 of the foot support stay fixing member 190 on the lower surface of the foot bottom 106, and the foot support stay 170 is removed. The distal end 109 may be engaged with the engaging portion 113 of the foot support stay support 111).

  That is, the caregiver arranges the foot support stay 170 on the support 111 for the foot support stay only when adjusting the position of the user's foot to the “high position”. Accordingly, the caregiver is in a state where the foot support stay 170 is disposed with respect to the adjustment (high / low) of the user's foot (conventionally, the end portion of the foot support stay is disposed on the upper stage or the lower stage. It is not necessary to understand these two states). For this reason, the burden by a machine operation is not given with respect to the caregiver who cares a user.

  As described above, according to the foot bottom support mechanism of the bed apparatus 1 according to the present invention, when the caregiver adjusts the position of the user's foot tip, the manner of arrangement of the foot tip support stay 170 can be understood more than before. It becomes easy and the burden of a caregiver can be reduced more than before.

  The embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration is not limited to this embodiment, and the design and the like within the scope of the present invention are also within the scope of the claims. include.

  The present invention can be used for various bed devices such as a home care bed device, a facility care bed device, and a hospital bed device.
