Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention belongs to the technical field of beds, and particularly to the technical field of nursing beds capable of adjusting the bending and stretching positions of knees and the like according to the physique of the user. In this specification, the nursing bed is a sick person,
It is not limited to a bed for nursing a user such as an elderly person or a disabled person, but broadly refers to a bed having bending and stretching functions such as knee bending and reclining.

[0002]

2. Description of the Related Art For example, Japanese Patent Application Laid-Open No. 9-84836 (Prior Art 1), Japanese Patent Application Laid-Open No. 9-313544 (Prior Art 2) and Japanese Utility Model Laid-Open Publication No. There is one disclosed in Japanese Patent No. 1059 (prior art 3). And in these prior arts, the curved bottom member capable of bending at a predetermined curvature was used for the bending portion.

That is, in the prior arts 1 and 2, the first frame and the second frame extending in the longitudinal direction (the height direction of the user) can be bent and stretched around the pivot to connect the first frame and the second frame to each other in the longitudinal direction. A hinge member was used. In order to adjust the position of the bent portion of the bottom (upper surface) of the bed according to the user's physique, in the prior art 1, the joint position between the hinge member and both frames can be adjusted in the longitudinal direction. Was designed to. on the other hand,
In the prior art 2, a hinge member having two pivots is used at a predetermined interval in the longitudinal direction, and one of the two pivots is fixed, so that the position of the bent portion is adjusted in two steps in the longitudinal direction. I was able to do it.

Further, a curved bottom member that can be bent at a predetermined curvature has been used as a bottom member that covers the hinge member and forms a part of the floor surface (upper surface of the bottom). Also, the hinge member that supports the curved bottom member in a bent state has an upper surface close to the pivot with an appropriate curvature so that a curved surface can be formed along the bottom surface of the curved bottom member.

[0005] Here, according to the prior art 3, the curved bottom member is configured such that a plurality of inverted trapezoidal strip-shaped bottom members are connected to each other at their upper surfaces so as to be bendable. That is, the plurality of strip-shaped bottom members are integrally connected to each other on the upper surface side, and have an appropriate gap on the lower surface side. Therefore, when the strip-shaped bottom member is curved upwardly convex, the connection portion on the upper surface side of the strip-shaped bottom member is bent, and the range of the curvature where the gap is collapsed and curved on the lower surface side is appropriately limited. I have. That is, the curved bottom member used in each conventional technique is a flexible integral member made of a hollow thermoplastic resin.

In the prior arts 1 and 2, it is necessary to prevent such a curved bottom member from being bent in the opposite direction when the hinge member is extended. For example, countermeasures such as providing a reverse bending regulating member on the gap side of the curved bottom member or providing a linear support member beside the hinge member provided with the curved bottom member are essential.

[0007]

However, in each of the above-described curved bottom members according to the prior art, since a plurality of strip-shaped bottoms are integrally connected on the upper surface side, the cross-sectional shape is large, and an appropriate gap is formed on the lower surface side. Must be formed between the strip-shaped bottoms. Therefore, since the size of the curved bottom member is large and the shape is complicated, the mold for manufacturing the curved bottom member is also greatly complicated, and the manufacturing cost of the mold is considerably increased.
The price of a curved bottom member is also high. Further, in order to mold such a curved bottom member, it is difficult to manufacture the curved bottom member by extrusion molding because the width of the curved bottom member in the longitudinal direction is large, and it has to be manufactured by injection molding. As a result, the manufacturing cost of the curved bottom member is still high, and the rise in the price of the curved bottom member has hindered the inexpensive provision of a care bed whose bending position can be adjusted.

Therefore, an object of the present invention is to provide a more inexpensive nursing care bed capable of adjusting the bending and stretching positions.

[0009]

SUMMARY OF THE INVENTION The present invention is directed to a first frame and a second frame extending in a longitudinal direction, and the frames are connected to each other in a longitudinal direction so as to be able to bend and extend, and to be connected to the frames. In a nursing bed that is adjustable in bending and stretching position having a hinge member that is adjustable in the longitudinal direction, and a bottom member that covers both the frame and the hinge member and forms a floor surface, the hinge member of the bottom member includes What is covered is a nursing care bed whose bending position can be adjusted, characterized by a plurality of strip-shaped bottom members which are separate from each other.

That is, in the nursing care bed of the present invention in which the bending position can be adjusted, the portion corresponding to the above-described curved bottom member of each prior art is constituted by a plurality of strip-shaped bottom members which are separate from each other. Therefore, each strip-shaped bottom member is
Since it is molded separately, the molding die is much smaller when molding the strip-shaped bottom member of the present invention than when molding a large curved bottom member that is integrally molded. As a result, the production cost of the mold is much lower than that of the conventional technology, and it is possible to manufacture the required number of strip-shaped bottom members in one bed at a lower cost. It is possible to provide a comfortable nursing bed.

In this case, it is desirable that the plurality of strip-shaped bottom members have the same shape. If the strip-shaped bottom members have the same shape, they become a single standard product, so there is no need to prepare a plurality of molding dies, and the strip-shaped bottom members can be manufactured more inexpensively. Become like Further, in the nursing care bed of the present invention in which the bending position can be adjusted, the bottom member does not need to be flexible, and the bending of the bending portion such as the knee portion does not cause any significant deformation of the bottom member. That is, in the present invention, since there is almost no deformation of the bottom member, the bottom member is prevented from being cracked even when used for a long time, and the life of the bottom member is long and the maintenance cost is low for a long time. It is suppressed.

Therefore, according to the present invention, not only can a bed for nursing care whose bending position can be adjusted be provided at lower cost, but also the maintenance cost of the bed can be reduced.

[0013]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention is characterized in that the bottom member covering the hinge member is a plurality of strip-shaped bottom members separately from each other, but these plurality of strip-shaped bottom members have the same shape. The bottom member covering the other parts may be the same strip-shaped bottom member. With such a configuration, since all the bottom members are made of a single standard product, there is no need to prepare a plurality of molding dies, and it is possible to provide a nursing care bed that can adjust the bending position more flexibly at a lower cost. become able to. Furthermore, if appropriate gaps are provided between the strip-shaped bottom members, the air permeability between the top and bottom of the bottom is improved through these gaps, and the moisture of the mat or the futon placed on the bottom is easily released. Therefore, the feeling of use of the bed of the present invention becomes more comfortable.

Here, it is desirable that the strip-shaped bottom member is made of an extruded product having a constant cross-sectional shape. With such a configuration, the strip-shaped bottom member can be manufactured at a lower cost by extruding an inexpensive thermoplastic resin or the like, so that a care bed capable of adjusting the bending and stretching position can be manufactured at a lower cost. Can be provided.

Further, the hinge member has at least a pair of left and right bolts or pins having a T-shaped head protruding upward for each of the strip-shaped bottom members, and each of the strip-shaped bottom members is connected to the head. It is still more desirable to adopt a configuration having an engagement groove having a T-shaped cross section for engagement. That is, by inserting the strip-shaped bottom member from the lateral direction of the bed, such that the heads of the locking members such as a pair of left and right bolts or pins are inserted into the engagement grooves of the strip-shaped bottom member made of the extruded product, The strip-shaped bottom member is fixed to the bed. Then, it becomes very easy to insert each strip-shaped bottom member into the bed of the present invention. In addition, since the locking members such as bolts and pins can be easily attached and detached, it is easy to reposition the positions properly, and there is an effect that the adjustment of the bending / extending position becomes easier.

Further, it is more preferable that the strip-shaped bottom member has a lightening hole formed so as to communicate left and right. This is because the strip-shaped bottom member having such a configuration reduces the material cost and the weight by the thickness of the lightening hole, and further improves the heat retention. Although the above description has been made with a focus on the characteristics of the strip-shaped bottom member, the adoption of the strip-shaped bottom member allows the hinge member to be manufactured at a lower cost, unlike the conventional technology. . That is, in the bed of the present invention, of the hinge member, a connecting portion that holds each of the strip-shaped bottom members and is coupled to the first frame or the second frame is configured by a linear member. And still better.

The reason is that a rectangular bottom member is employed instead of the curved bottom member, and therefore, it is inconvenient if the connecting portion is formed of a member having a curved shape as in the prior arts 1 and 2. is there. That is, when the hinge member is bent, the bottom may be formed with an appropriate curve, but when the hinge member is extended,
It is inconvenient if the strip-shaped bottom member drops along the connecting portion of the hinge member. Therefore, if both connecting portions of the hinge member are formed of a linear member, such a functional disadvantage is eliminated. In addition, there is an effect that the manufacturing cost of the hinge member can be reduced, and the cost can be further reduced.

Conversely, when the user's thigh is short, the hinge member 3 is connected to both frames 1 and 2 according to the user's physique, as shown by enlarging the portion B in FIG. 4 in FIG. 5B. 2 and is fixed in the waist direction (right side in the figure).

In order to fix the hinge member 3 to the frames 1 and 2 by shifting the longitudinal position with respect to the frames 1 and 2, first, the pivot portion 33 of the hinge member 3 is placed just below the knee joint of the user. The position of the hinge member 3 with respect to the two frames 1 and 2 is adjusted so that the frame is positioned. Here, on the side surfaces of the linear members 31 and 32 of the hinge member 3, a plurality of sets of fixing pin holes 30 are formed penetrating in the left-right direction. A corresponding pair of fixing pin holes 10, 20 are formed. Therefore, when adjusting the position by shifting the hinge member 3, the fixing pin holes 10 and 20 formed in both the frames 1 and 2 are adjusted.
And the position is adjusted so that one of the plurality of sets of fixing pin holes 30 formed in both linear members 31 and 32 of the hinge member 3 faces each other. That is, both frames 1,

Can be performed in a stepwise manner at the pitch where is formed.

Then, a fixing pin (not shown) is inserted into a plurality of fixing pin holes 30 penetrated in the left and right directions on the side surfaces of the frames 1, 2 and the hinge member 3, and the hinge member 3 is inserted.
And the two frames 1 and 2 are connected to each other. At this time, of the strip-shaped bottom members 6 ′, those that hinder the connection between the linear members 31, 32 and the frames 1, 2 are pulled out in either the left or right direction and removed from the hinge member 3.

Then, the hinge member 3 is connected to both frames 1, 2.
, An open portion is generated in one of the connecting portions 31 and 32 of the hinge member 3. Therefore,
The strips removed to the side opposite to the side from which the strip-shaped bottom member 6 ′ is removed of the linear members 31, 32, that is, to the side of the straight member (31 or 32) opposite to the side where the hinge member 3 is shifted. The bottom member 6 'is moved. as a result,
Since the relocated strip-shaped bottom member 6 ′ forms the bottom of the bed, the relocated strip-shaped bottom member 6 ′ is fixed by bolts 40.

The one connecting portion 31 of the hinge member 3
The first frame 1 and the first frame 1 are slidable by engaging with each other in cross-sectional shape. Similarly, the other connecting portion 32 of the hinge member 3 and the connecting portion 21 of the second frame 2 are slidable by engaging with each other in cross-sectional shape. Further, as described above, in the present embodiment, a plurality of sets of fixing pin holes are formed on the side surface of the hinge member 3, and a set of fixing pin holes corresponding to each side surface of both frames 1 and 2 are formed. . However, conversely, a set of fixing pin holes is formed on each of the side surfaces of the linear members 31 and 32 of the hinge member 3, and a plurality of sets of fixing pin holes corresponding to the respective side surfaces of the frames 1 and 2. May be formed. Alternatively, a configuration in which a plurality of sets of fixing pin holes are formed on the side surfaces of both the hinge member 3 and both frames may be adopted.

As shown in FIGS. 5A and 5B, five strip-shaped bottom members 6, 6 'covering the hinge member 3.
Are the same standard products having the same shape separately from each other, and the same appropriate spacing is provided between the strip-shaped bottom members 6, 6 'adjacent to each other. That is, the strip-shaped bottom members 6, 6 'are arranged at regular intervals at a predetermined pitch in the longitudinal direction. A pair of left and right bolts 40 (see FIG. 2) having T-shaped heads projecting upward by a predetermined distance are screwed into the hinge member 3 for each of the strip-shaped bottom members 6, 6 '.

Here, as shown in FIG. 6, the strip-shaped bottom members 6, 6 'are made of an extruded product made of a polypropylene resin (PP) and having a constant sectional shape. The openings at the left and right ends of the 'are sealed by caps (not shown). Each of the strip-shaped bottom members 6 and 6 ′ has an engagement groove 61 having a T-shaped cross section opened downward and engaged with the T-shaped head of each bolt 40 described above.
At the center, and has an axially symmetric cross-sectional shape having a pair of lightening holes 60 formed to communicate left and right. Also, in order to facilitate manufacture and not to damage the fingers and mats of the workers, the corners of the strip-shaped bottom members 6, 6 'are provided with appropriate rounds, and the corners are formed to prevent stress concentration. Is also fitted with the appropriate ares. In addition, the thickness of each part of the strip-shaped bottom members 6, 6 'is formed substantially constant. The uppermost portion of the portion forming the engagement groove 61 and the ceiling portion forming the upper surface are joined by a wall dividing the pair of lightening holes 60, and the vertical compressive strength is increased. .

The wide bottom member 7 is made of the same material as the above-mentioned strip-shaped bottom members 6, 6 ', except that the width of the user in the height direction is wide. Therefore, the bottom members 6, 6 ', 7
Consists of two types of extruded products, that is, strip-shaped bottom members 6 and 6 'and a bottom member 7, and only two small extruded dies required for the production thereof are required.

(Effects of Embodiment 1) The bed for nursing care of which the bending position can be adjusted according to the present embodiment is constructed as described above, and exhibits three main effects as follows. First, according to the present embodiment, there is an effect that it is possible to provide a bed for nursing care whose bending position can be adjusted at a lower cost.

That is, in the nursing care bed of the present embodiment in which the bending position can be adjusted, the portions corresponding to the above-described curved bottom members of the related arts are, as described above, a plurality of strip-shaped bottom members which are separate from each other and have the same shape. 6, 6 '. Therefore, since each of the strip-shaped bottom members 6, 6 'has the same standard as each other and is molded separately, a plurality of the plurality of strip-shaped bottom members in this embodiment are formed rather than molding a large curved bottom member integrally molded. The molding of the narrow strip-shaped bottom members 6, 6 'requires a much smaller mold.

Further, since the strip-shaped bottom members 6, 6 'are formed by extrusion molding with a constant cross-sectional shape, the strip-shaped bottom members 6, 6' can be made even more inexpensive by extruding an inexpensive polypropylene resin. Can be manufactured. Further, since the strip-shaped bottom members 6, 6 'have the lightening holes 60 formed so as to communicate left and right, the material cost is reduced by the lightening holes 60, the weight is reduced, and the heat insulation property is further improved. Is also good.

In addition, as described above, the bottom members 6, 6 ', 7 are composed of two types of extruded products, that is, strip-shaped bottom members 6, 6' and a bottom member 7. Only two types of small extrusion molds are required. Therefore, the bottom members 6, 6 ',
Since the manufacturing cost of the molding die required for 7 can be reduced, the bottom members 6, 6 ', 7 can be manufactured more inexpensively.

Therefore, according to the present embodiment, the production cost of the mold is much lower than that of the prior art, and the required number of strip-shaped bottom members 6, 6 ', 7 for one bed can be manufactured at lower cost. can do. As a result, there is an effect that it is possible to provide a care bed capable of adjusting the bending position at a lower cost. Secondly, according to the present embodiment, there is an effect that the maintenance cost of the nursing care bed whose bending position can be adjusted can be reduced.

That is, the bottom members 6, 6 ', 7 are not required to be flexible, and the bent bottom members 6, 6' are not required to bend when the hinge member 3 at the knee portion is bent. Then, since there is almost no deformation of the bottom members 6, 6 ', 7, even if the bottom members 6, 6', 7 are used for a long time,
7 is prevented from being cracked. As a result, the service life of the bottom members 6, 6 ', 7 is long, and the maintenance cost can be kept low for a long period of time in the care bed of the present embodiment in which the bending position can be adjusted.

Therefore, according to the present embodiment, not only can the nursing care bed capable of adjusting the bending and stretching position be provided at lower cost, but also the maintenance cost of the bed can be reduced. Thirdly, according to the nursing care bed of the present embodiment in which the bending position can be adjusted, there is an effect that the bending position of the knee portion can be easily adjusted while having a low-cost configuration as described above.

That is, the hinge member 3 has a pair of left and right bolts 40 each having a T-shaped head projecting upward for each of the strip-shaped bottom members 6, 6 '. , And has an engagement groove 61 having a T-shaped cross section for engaging with the heads of both bolts 40. Then, the strip-shaped bottom members 6, 6 'are inserted from the lateral direction of the bed such that the heads of the pair of left and right bolts 40 are inserted into the engagement grooves 61 of the strip-shaped bottom members 6, 6' made of an extruded product. By this means, the strip-shaped bottom members 6, 6 'are fixed to the bed.

More specifically, FIG. 5A and FIG.
As is clear from the comparison between (b) and (b), the longitudinal position of the hinge member 3 can be moved relative to the frames 1 and 2 by moving the three strip-shaped bottom members 6 '. That is, by moving three strip-shaped bottom members 6 ′ of the strip-shaped bottom members 6, 6 ′ locked to the connecting portions 31, 32 of the hinge member 3 with the bolts 40, the thigh portion has the shortest thigh. For both the user and the user with the longest thigh, the pivot 33 of the hinge member 3 can be adapted to the bending position of the knee joint. As a matter of course, by moving one or two of the three strip-shaped bottom members 6 ′, the pivot portion 33 of the hinge member 3 can be adjusted to an intermediate position. Therefore, the position of the pivot portion 33 of the hinge member 3 can be adjusted in the longitudinal direction with a step width corresponding to the pitch of the strip-shaped bottom member 6 '.

As a result, it becomes extremely easy to insert each of the strip-shaped bottom members 6 ′ into the bed of the present embodiment and to adjust the position of the pivot portion 33 of the hinge member 3 according to the physique of the user. Further, since the fixing pins and the bolts 40 provided in the fixing pin holes 10, 20, and 30 are easily attached and detached, it is easy to appropriately re-arrange their positions, and the bending and extension positions can be easily adjusted. There is an effect that there is.

Although the above description has been made focusing on the features of the strip-shaped bottom members 6, 6 'and the bottom member 7, the adoption of these components allows the hinge member 3 to be configured at a lower cost, unlike the prior art. Can be manufactured. That is, in the present embodiment, since both connecting portions 31 and 32 of the hinge member 3 are constituted by the linear members as described above, the joint members 31 and 32 can be manufactured at a lower cost than the curved members. In this respect, the cost can be reduced as compared with the conventional technology. Accordingly, there is an effect that the manufacturing cost of the two connecting portions 31 and 32 of the hinge member 3 can be reduced.

(Modification 1 of Embodiment 1) As Modification 1 of this embodiment, the bending and stretching position can be adjusted by changing the cross-sectional shape of the strip-shaped bottom members 6, 6 'to a simpler shape as shown in FIG. It is possible to implement a comfortable nursing bed. According to this modification, the manufacturing cost of the strip-shaped bottom members 6 and 6 ′ can be further reduced, so that there is an effect that a care bed whose bending position can be adjusted can be provided at a lower cost.

(Modification 2 of Embodiment 1) As a modification 2 of the present embodiment, as shown in FIG.
Can be used, and a nursing care bed in which all parts of the bottom can be adjusted only by strip-shaped bottom members 6 of the same standard arranged at predetermined intervals can be implemented. With such a configuration, all the bottom members are made of a single standard product (strip-shaped bottom member 6).
There is no need to prepare a plurality of molds, and it is possible to provide a nursing bed that can adjust the bending position more inexpensively. Further, since appropriate gaps are provided between the strip-shaped bottom members 6, air permeability between the top and bottom of the bottom is improved through these gaps, and moisture of the mat or the futon placed on the bottom is reduced. It becomes easy to fall out.
Therefore, according to the nursing care bed of this modified embodiment in which the bending position can be adjusted, not only the manufacturing cost is further reduced, but also the feeling of use becomes more comfortable.

[0043]

As described above in detail, according to the nursing care bed of the present invention capable of adjusting the bending position, the inexpensive strip-shaped bottom members 6, 6 'are employed without using the curved bottom members. Thus, there is an effect that the cost is lower than each of the above-mentioned prior arts. In addition, since the bottom lasts long even at the bent portion of the knee, there is also an effect that the maintenance cost can be reduced.
