Description

  The present invention relates to a mattress device in which a mattress main body is constituted by an air tube.

  In general, a mattress device includes a mattress main body and a bag-shaped exterior body in which the mattress main body is accommodated. As a mattress device used for a hospital bed, there may be used a mattress device formed by arranging a plurality of air tubes in parallel as shown in Patent Document 1, instead of using a coil spring as the mattress body.

  According to the mattress body formed by arranging a plurality of air tubes side by side, it is possible to control the pressure of the compressed air supplied to each air tube. Therefore, the user may be able to adjust the hardness of the mattress body partially or entirely according to his / her preference.

  In addition, when a bedridden patient uses the mattress device having the above configuration for a long period of time, for example, if the air pressure supplied to each air tube is periodically changed, the patient has a heavy part of the body such as the buttocks as an air tube. Can reduce the incidence of humiliation because it does not continue to be squeezed for a long time with the same strength.

  By the way, when the mattress body is configured by arranging a plurality of air tubes, both ends in the longitudinal direction of the air tubes, which are both ends in the width direction of the mattress body, are easily deformed with respect to the load. is there. In other words, both ends of the mattress body in the width direction may be too soft compared to other portions.

  Therefore, if the user touches or sits on the end in the width direction of the mattress body, which is the end in the longitudinal direction of the air tube, the body is unstable due to large deformation of the end. Therefore, it is not preferable. In addition, if both ends of the air tube are easily deformed, the effective use area of the mattress device may be reduced.

Therefore, in Patent Document 2, a frame-like body formed of a relatively hard elastic material is provided at the periphery of a plurality of air tubes arranged in parallel to form a mattress body, and the periphery of the mattress body is defined as the frame-like body. Reinforced by.
JP 2000-354613 A Japanese Patent No. 3560800

  However, if a mattress body is configured by providing a frame body around the periphery of a plurality of air tubes arranged side by side, the mattress body may be enlarged due to the frame body, or the air tube and the frame body may be Because it is easy to separate, there are times when it becomes uncomfortable.

  Moreover, since the degree of compression with respect to the load, that is, the hardness, differs greatly between the end of the air tube and the frame-like body, the change in the hardness at the boundary between the air tube and the frame-like body becomes large, and the user May cause discomfort.

  In the present invention, the end in the width direction of the mattress body configured by arranging the air tubes can be reliably reinforced with a simple configuration, and the reinforcement at the end in the width direction of the mattress body It is an object of the present invention to provide a mattress device in which the temperature does not change rapidly.

The present invention is a mattress device including a mattress main body and a bag-shaped exterior body that accommodates the mattress main body.
The mattress body is
A plurality of air tubes arranged side by side along the longitudinal direction of the mattress body; and
A strip-shaped base portion and a plurality of reinforcing pieces provided at predetermined intervals on the base portion are formed of an elastic material, and the reinforcing piece is attached to at least one end portion in the width direction of the mattress body. And a reinforcing member that is detachably inserted between the end portions.

  The height of the reinforcing piece of the reinforcing member is set to be substantially the same as the height of the air tube, and the reinforcing member is located adjacent to the lower surface of the mattress body and the reinforcing piece is adjacent to the air tube. It is preferable to be inserted between the end portions of the two.

  It is preferable that the corner portion of the reinforcing piece located at the end in the width direction on the upper surface side of the mattress main body is formed on a slope.

  The reinforcing member is preferably provided by positioning the base portion on a side surface of the mattress body and inserting the reinforcing piece between the end portions of adjacent air tubes.

  It is preferable that the reinforcing piece is formed in a tapered shape in which the height dimension gradually decreases from the base end connected to the base portion toward the tip.

  It is preferable that the reinforcing member is detachably provided at an end of the mattress body in the width direction.

According to this invention, since the reinforcing piece of the reinforcing member is detachably inserted between the ends of the adjacent air tubes, the end of the mattress body in the width direction can be reinforced by the reinforcing piece. Moreover, since the reinforcing member is not easily separated from the air tube by inserting the reinforcing piece between the ends of the adjacent air tubes, the reinforcing piece can reliably reinforce the end of the air tube, Furthermore, since the reinforcing piece enters between the end portions of the air tube, the change in hardness at the end portion in the width direction of the mattress body can be moderated.

An embodiment of the present invention will be described below with reference to the drawings.
1 to 6 show a first embodiment of the present invention. FIG. 1 is a perspective view showing a hospital bed 1, which includes a bed frame 2. A pair of legs 3 are rotatably provided at both ends in the longitudinal direction of the lower surface of the bed frame 2 so as to be held at a predetermined rotation angle. If the rotation angle of the pair of legs 3 is adjusted, the support height of the bed frame 2 can be changed.

  The bed frame 2 is provided with a headboard 5a at one end in the longitudinal direction and a footboard 5b at the other end, and a pair of support pipes 8 provided at predetermined intervals on one side surface in the width direction. Side rails 6 are supported on the pair of support tubes 8 by inserting a pair of leg rods 7 in a detachable manner.

  A mattress device 11 is placed on the upper surface of the bed frame 2. The mattress device 11 includes a mattress main body 12 (shown in FIGS. 2, 5, and 6) and a bag-shaped exterior body 13 that houses and covers the mattress main body 12.

  The mattress body 12 has a rectangular base sheet 14 as shown in FIG. On the upper surface of the base sheet 14, a pair of holding belts 15 spaced apart at a predetermined interval in the width direction are provided along the longitudinal direction. The holding belt 15 is sewn to the base sheet 14 at a predetermined interval in a slack state. Thereby, the holding belt 15 forms a plurality of holding portions 15a.

  An air tube 17 having a rectangular cross section formed by an airtight resin sheet is inserted and held in the holding portion 15a. As shown in FIGS. 3 and 6, folded pieces 17a are formed on the upper and lower ends of the end surface of the air tube 17, and hooks 18 are provided on the folded pieces 17a.

  As shown in FIG. 2, the width dimension of the base sheet 14 is formed longer than the length dimension of the air tube 17. A pair of hooks 21 are provided to be fitted to hooks 18 provided on the piece 17a.

  That is, the width dimension of the base sheet 14 is formed long enough to fit the hook 21 to the hook 18 of the air tube 17. By fitting the hooks 18 and 21 together, the plurality of air tubes 17 arranged side by side are held by the base sheet 14 so as not to move. The length dimension of the base sheet 14 is set so as to protrude from both ends of the plurality of air tubes 17 arranged side by side with a length corresponding to the height dimension of the air tubes 17.

  As shown in FIG. 1, the exterior body 13 is formed by a town 13 a provided on the outer peripheral surface of the mattress body 12 and a mirror 13 b (only the upper surface is shown) provided on the upper and lower surfaces. Nearly the entire length of the upper edge of the town 13a and the peripheral portion of the mirror surface 13b on the upper surface side are connected by a fastener 19 so as to be opened and closed.

  When a plurality of air tubes 17 held by the holding belt 15 and arranged on the base sheet 14 are filled with compressed air of a predetermined pressure, the side surfaces of the adjacent air tubes 17 as shown in FIGS. Are elastically in close contact with each other.

  A reinforcing member 23 shown in FIGS. 4 to 6 is attached to one end of the mattress main body 12 in the width direction in a range indicated by A in FIG. 1, that is, a portion that is removed from the side fence 6 provided on the bed frame 2. The

  The reinforcing member 23 is provided on the base portion 23a at the same pitch as the interval between the strip-like base portion 23a and the air tube 17 held in parallel with the base sheet 14 by an elastic material such as semi-rigid urethane foam or polyurethane foam. A plurality of reinforcing pieces 23b are integrally formed. The reinforcing piece 23b has a rectangular side shape, and one of the pair of corners at the tip is formed on the slope 23c. Although not shown, the slope 23c may be formed on both of the pair of corners.

  5 and 6, the reinforcing member 23 has a pair of air tubes in which the base portion 23a is inserted between the lower surface of the air tube 17 and the upper surface of the base sheet 14, and the reinforcing pieces 23b are adjacent to each other. The mattress body 12 is inserted between 17 side surfaces and provided at the end in the width direction of the mattress body 12. At this time, the slope 23c formed at the corner of the reinforcing piece 23b is located at the end in the width direction on the upper surface side of the mattress body 12.

  Then, if the reinforcing member 23 is provided on the base sheet 14 with the air tube 17 held on the upper surface, the both ends of the base sheet 14 in the width direction are bent, and the hooks 21 provided at both ends are connected to the air tube 17. After fitting into the hook 18 of the folded piece 17 a on the end face, the air tube 17 is accommodated in the exterior body 13 together with the base sheet 14.

  According to the mattress device 11 having such a configuration, the reinforcing member 23 has the base portion 23a on the lower surface of the air tube 17 and the upper surface of the base sheet 14 in the range A of the one end in the width direction of the mattress main body 12 that is separated from the side fence 6. The reinforcing piece 23b is inserted between the side surfaces of a pair of adjacent air tubes 17 and provided.

  Therefore, one end portion in the width direction where the reinforcing member 23 of the mattress main body 12 is provided is reinforced by the reinforcing piece 23b, so that the portion corresponding to the longitudinal end portion of the air tube 17 is formed. Even if the user applies a load by putting his hand or sitting down, the air tube 17 is restricted from being greatly crushed by the load.

  As a result, when the user touches the end of the mattress body 12 in the width direction or sits down, the end of the air tube 17 is greatly compressed and deformed, and the user loses his / her balance and fluctuates. , And can be prevented from falling.

  If the interval between the plurality of reinforcing pieces 23b provided on the base portion 23a of the reinforcing member 23 is set to be narrower than the size in the width direction of an adult's hand, the user can reach the end of the mattress device 11 in the width direction. Since the hand always touches the reinforcing piece 23b, the end of the air tube 17 can be reliably prevented from being crushed by the reinforcing piece 23b.

  The reinforcing piece 23 b of the reinforcing member 23 is inserted and held between the side surfaces of the adjacent air tubes 17. That is, the side surfaces of the adjacent air tubes 17 are in close contact with each other in an expanded state due to air pressure, so that the reinforcing piece 23 b inserted between the side surfaces is elastically held by the air tubes 17.

  In addition, the base 23a of the reinforcing member 23 is held by the upper surface of the base sheet 14 and the lower surface of the air tube 17, and the holding state may be shifted depending on the weight of the user when the user lies on the mattress device 11. Absent.

Therefore, during use of the mattress apparatus 11, there is no necessity that the reinforcing piece 23a moves shift reinforcing member 23 is disengaged from between the side surface of the air tube 17 adjacent the mattress body 12, the reinforcing pieces 23a Thus, the reinforcement of the end portion in the width direction of the mattress body 12 can be reliably performed in a stable state.

A corner portion of the reinforcing piece 23a located on the upper surface side of the mattress body 12 is formed on a slope 23c. Therefore, the user's hand is prevented from being strongly pressed by the slope 23c provided at the corner of the reinforcing piece 23a when the user puts a hand on the end of the mattress device 11 in the width direction or sits down. can do.

  The hardness of the end portion in the width direction where the reinforcing member 23 of the mattress body 12 is provided is the hardness of the air tube 17 and the reinforcing piece 3 synthesized by the reinforcing piece 3 inserted between the air tubes 17. become.

For this reason, the end in the width direction reinforced by the reinforcing piece 23a of the reinforcing member 23 of the mattress main body 12 is in a state in which only the hardness of the reinforcing piece 23a is not transmitted to the user. Hard to give.

  That is, by inserting the reinforcing piece 3 between the air tubes 17, the boundary between the softness of the air tube 17 and the hardness of the reinforcing piece 3 is unlikely to occur. 12 end portions in the width direction can be reinforced.

  The reinforcing member 23 is detachably attached to the air tube 17. Therefore, when the side fence 6 is removed from the bed frame 2 and used, the fastener 19 connecting the town 13a and the mirror 13b of the exterior body 13 is opened, the reinforcing member 23 is removed from the end of the mattress body 12, and this You may make it mount | wear to the part corresponding to the location where the side fence 6 of the mattress main body 12 was provided.

  Alternatively, by preparing a plurality of reinforcing members 23, the reinforcing member 23 that reinforces the portion in the range A is left as it is, and the other reinforcing member 23 is attached to the portion where the side fence 6 was provided. It may be.

  As a result, one end in the width direction of the mattress body 12 is reinforced over almost the entire length in the longitudinal direction, so that the portion of the mattress body 12 that can be used effectively can be enlarged. The reinforcing member 23 may be provided not only at one end in the width direction of the mattress body 12 but also at the other end.

  7 to 9 show a second embodiment of the present invention. This embodiment shows a modification of the reinforcing member 123, and the reinforcing member 123 is similar to the first embodiment in that the base plate 123a having a band plate shape is formed of an elastic material such as semi-rigid urethane foam or polyurethane foam. A plurality of reinforcing pieces 123b provided on the base 123a are integrally formed at the same pitch as the interval between the air tubes 17 held side by side.

  The base 123a is formed thicker than the reinforcing piece 123b. Accordingly, the base 123a is less likely to be deformed with respect to the load than the reinforcing piece 123b. That is, it is formed hard. The upper and lower surfaces of the reinforcing piece 123b are tapered by a pair of inclined surfaces 123c whose width (hardness) gradually decreases from the base end connected to the base 123a toward the tip.

  As shown in FIG. 8, the reinforcing member 123 configured as described above has the base 123a positioned on the side surface in the width direction of the mattress body 12, that is, the end surface of the air tubes 17 arranged side by side, and the reinforcing pieces 123b are adjacent to the adjacent air tubes 17. It is provided by being inserted between the end portions.

  In this embodiment, as shown in FIG. 7, the reinforcing member 123 is provided at both ends in the width direction of the mattress main body 12 over the entire length in the longitudinal direction. However, as in the first embodiment, the reinforcing member 123 is the mattress main body. 12 may be provided only on one side in the width direction, or may be provided partially in the longitudinal direction.

  If the reinforcing member 123 is thus provided at the end in the width direction of the mattress main body 12, the end in the width direction of the mattress main body 12 is the reinforcing piece 123 b of the reinforcing member 123 inserted into the end of the air tube 17. Thus, the end portion of the air tube 17 is reinforced, and the side surface portion of the mattress body 12 is reinforced by the base portion 123a provided in contact with the end surface of the air tube 17.

As for the hardness in the width direction of the mattress body 12, the portion of only the air tube 17 indicated by X in FIG. 8 is the softest, the portion into which the reinforcing piece 123b indicated by Y is inserted is soft, and the base portion 123a indicated by Z is located. The part becomes the hardest. That is, the end in the width direction of the mattress body 12 gradually becomes hard as going outwardly, since it is difficult occur boundaries hardness greatly differs, given example flame Kunar discomfort to the user.

  Moreover, the reinforcing piece 123b of the reinforcing member 123 is formed in a tapered shape whose height dimension gradually decreases inward in the width direction of the mattress body 12 by a pair of inclined surfaces 123c. If the height dimension of the reinforcing piece 123b is low, the degree of reinforcement of the mattress body 12 is small.

  Therefore, the reinforcement of the end portion in the width direction of the mattress main body 12 by the reinforcing piece 123b of the portion indicated by Y in FIG. 8 gradually increases toward the outer side in the width direction, so that also in the width direction of the mattress main body 12 The change in the hardness of the end portion of the head becomes gradual, and the feeling given to the user is improved. That is, it becomes difficult for an extreme boundary to be generated in the end of the mattress body 12 in the width direction.

In the first embodiment, the base of the reinforcing member is positioned on the lower surface of the air tube. However, the base may be positioned on the end surface of the air tube.
In the first and second embodiments, the reinforcing member is detachably provided at the end of the mattress body in the width direction. However, the reinforcing piece or base of the reinforcing member is attached to the end of the air tube of the mattress main body. The reinforcing member may be fixed to the mattress main body by bonding to the portion.

  If the reinforcing member is fixedly provided on the mattress body, the mattress body can be used in a stable state since the reinforcing member does not move during use because it is detached from the end of the mattress body.
