Description

The present invention relates to a support device that supports the upper body of a lying user.

To prevent acid reflux, including reflux esophagitis, and acid reflux, which can cause heartburn when you wake up, it is effective to raise your back to some extent (generally about 15 cm to 20 cm) at bedtime. Is. Focusing on this point, the applicant has developed a mat capable of raising the back that can easily realize such a sleeping posture (see Non-Patent Document 1). According to the mat, it is possible to support the upper body of the lying user at a predetermined angle.

On the other hand, not only is there an individual difference in the optimum degree of back-raising, but even when the same person uses it, the desired degree of back-raising varies depending on the situation at that time. Therefore, in order to deal with such a problem, it is conceivable that the angle for supporting the upper body (support angle) can be adjusted. Here, a conventional mechanism that allows the support angle to be adjusted is disclosed in, for example, Patent Document 1.

In Patent Document 1, the backrest plate that receives the upper body of a lying user is made rotatable on a rotation axis, and the support angle can be adjusted by fixing the backrest plate at an arbitrary position using an angle adjusting fixing screw. A simple backrest bed is disclosed.

According to the support angle adjusting mechanism disclosed in Patent Document 1, a sufficiently strong support member (along the upper surface of a bed or the like) is used to fix the backrest plate at an arbitrary angle so as to withstand the weight of the user. Components such as (a member that extends) and an angle scale plate (a member that enables screw fixing of the backrest plate) are indispensable. Therefore, if a mechanism similar to this is adopted to make the support angle adjustable, it is difficult to make a product with a simple configuration that can be easily used.

In view of the above-mentioned problems, an object of the present invention is to provide a support tool that makes it easy to have a simple configuration while making it possible to adjust the support angle of the upper body of a lying user.

The support tool according to the present invention is a tool that is arranged on a base surface such as a floor and supports the upper body of a lying user, and is movable with respect to the main body portion that receives the upper body portion with the head on the front side and the main body portion. It is provided with a projecting portion provided so as to project from the main body portion, and the rear side portion of the main body portion and the projecting direction tip portion of the projecting portion are arranged so as to be supported by the base surface. By moving the protruding portion, the angle of the main body portion with respect to the base surface in a lateral view can be adjusted. According to this configuration, while the support angle of the upper body of the lying user can be adjusted, it becomes easy to make a simple configuration.

More specifically, as the above configuration, the protruding portion is provided so as to be rotatable by a shaft extending laterally, and the angle can be adjusted by changing the amount of rotation of the protruding portion. good. Further, more specifically, the main body portion has a substantially plate shape having an upper surface and a lower surface, the shaft is set in the vicinity of the lower surface, and the upper surface is formed so as to receive the upper body. The protruding portion may be formed so as to protrude from the shaft and increase the angle as the amount of rotation is increased from the basic state of protruding substantially forward.

Further, more specifically, the configuration may be such that the lower surface of the protruding portion in the basic state and the portion of the lower surface on the rear side of the axis are included in the same plane. According to this configuration, the contact area between the support tool and the base surface can be made as large as possible to further stabilize the posture of the support tool, and a large load is locally suppressed on both the support tool and the base surface. Is possible.

Further, more specifically, the main body portion may be formed so that the thickness increases from the rear end portion to the front end portion. According to this configuration, the effect of raising the back can be obtained even if the support tool is used with the protruding portion as the basic state. More specifically, the ratchet mechanism may be used to change the amount of rotation in a plurality of stages.

According to the support tool according to the present invention, it is possible to adjust the support angle of the upper body of the lying user, but it is easy to make a simple configuration.

It is explanatory drawing about the structural example of support tool 1. It is explanatory drawing about the usage form of the support tool 1. It is explanatory drawing about another use form of support tool 1. It is explanatory drawing about still another usage form of the support tool 1.

An embodiment of the present invention will be described with reference to each drawing. FIG. 1 is a schematic perspective view of the support tool 1 according to the present embodiment. FIG. 2 is a schematic configuration diagram of the support tool 1 viewed from the side, and shows both the first form S1 in which the support angle θb is the minimum θb1 and the second form S2 in which the support angle θb is the maximum θb2. Shown. Further, FIG. 3 is an external perspective view of a sample of the support tool 1.

In the following description, the vertical, horizontal, and front-back directions (directions orthogonal to each other) are as shown in each figure, and "lateral" corresponds to the left-right direction. Further, the support angle θb is an angle for supporting the upper body of the user (the angle of the degree of raising the back), and corresponds to the angle of the upper surface 11a of the main body 11 with respect to the base surface F viewed from the side in the support tool 1. ..

As shown in FIG. 1 and the like, the support tool 1 includes a main body portion 11 and a protruding portion 12. Further, as shown in FIG. 2, the support tool 1 is arranged on a base surface F such as a floor, and is a tool for supporting the lying user with his / her upper body raised.

The main body 11 has a substantially plate-like shape having a flat upper surface 11a and a lower surface 11b, respectively, and is formed on the upper surface 11a so as to receive the upper body of a user lying with his head on the front side. The main body 11 is configured by arranging a cushion material on the upper side of the frame, and is considered to elastically support the upper body of the user and provide a comfortable feeling of use.

The upper surface 11a has a rectangular shape having front and rear and left and right sides, and is formed in a size sufficient to receive the upper body of the user. The shape and size of the lower surface 11b are the same as those of the upper surface 11a. Further, in the lateral view, the main body portion 11 is an isosceles triangle having the rear end portion 11c as the apex, the upper surface 11a and the lower surface 11b as equal sides, and the apex angle of about 9 degrees (almost equivalent to the angle θb1 shown in FIG. 2). It has the shape of. As described above, the main body portion 11 is formed so as to increase in thickness from the rear end portion 11c toward the front end portion 11d.

The protruding portion 12 is movable with respect to the main body portion 11 and is provided so as to protrude from the main body portion 11. More specifically, the projecting portion 12 projects from a laterally extending shaft 13 set in the vicinity of the lower surface 11b of the main body portion 11 and is rotatably provided by the shaft 13. The size of the protruding portion 12 in the left-right direction is substantially the same as the size of the main body portion 11 in the left-right direction. Further, the position of the shaft 13 in the front-rear direction is preferably on the front side of the center of the main body 11 in the front-rear direction from the viewpoint of posture stability and the like. Only about 20 to 30% of the size in the front-back direction is on the rear side.

The range in which the protrusion 12 can rotate is from the basic state in which the protrusion 12 protrudes forward and is substantially parallel to the lower surface 11b (the state in which the support tool 1 is in the first form S1), and the protrusion 12 is the lower surface 11b. The range is up to a state in which the support tool 1 is in a substantially vertical state (a state in which the support tool 1 is in the second form S2). In the first form S1, the positions of the front ends of the main body 11 and the protruding portion 12 in the front-rear direction are substantially the same. A ratchet mechanism is adopted for the shaft 13, and the amount of rotation of the protruding portion 12 is changed to a plurality of stages (for example, 13 stages), and the protruding portion 12 is fixed at the changed position (angle θa shown in FIG. 1). It is possible to prevent it from moving in the direction in which becomes smaller. As described above, in the support tool 1, a mechanism for fixing the protrusion 12 at the position where the amount of rotation is adjusted is also provided in the vicinity of the shaft 13, which is advantageous in terms of simplification of the configuration, weight reduction, and miniaturization. ..

Specifically, when increasing the angle θa (the angle between the protruding portion 12 and the lower surface 11b), the protruding portion 12 may be rotated in that direction. On the contrary, when reducing the angle θa, first, the protrusion 12 is rotated until the angle θa becomes 90 degrees or more to unlock the ratchet mechanism, and the protrusion 12 is turned in the opposite direction until the angle θa becomes 0 degrees. After rotating to, the protrusion 12 may be rotated again in the direction in which the angle θa increases.

In the deformation range from the first form S1 to the second form S2, as the angle θa is increased, the distance between the lower surface 11b and the protruding portion 12a of the protruding portion 12 becomes longer and the protruding portion 12a moves backward. However, as shown by the dotted arrow in FIG. 2, the support angle θb also increases. The position of the shaft 13 in the front-rear direction is set sufficiently closer to the front side than the center of the main body portion 11 in the front-rear direction, and the position of the tip portion 12a in the protruding direction is the deformation range from the first form S1 to the second form S2. All of them are on the front side of the shaft 13. Therefore, even if a load due to the weight of the user is applied to the main body portion 11, the protruding portion 12 can firmly receive this load.

As shown in FIG. 2, the support tool 1 is arranged so that the rear end portion 11c of the main body portion 11 and the protruding portion 12a of the protruding portion 12 are supported by the base surface F. As a result, the main body 11 is in a state where it can support the upper body of the lying user. Further, the support angle θb at this time can be adjusted in the range of θb1 to θb2 by changing the amount of rotation of the protruding portion 12.

Regarding these angles, θb1 is set to 9 degrees and θb2 is set to 23 degrees in the present embodiment, but different angles may be set depending on various circumstances. The user can maximize the effect of the support tool 1 by adjusting the amount of rotation of the protrusion 12 so as to obtain the optimum support angle θb for himself / herself. If the support tool 1 is used during sleep or the like, it can suppress acid reflux including reflux esophagitis and gastric acid reflux which causes heartburn when waking up.

Further, in the support tool 1 in the first form S1, since the protruding portion 12 and the lower surface 11b are substantially integrated, a wide range of the lower surface 11b comes into contact with the base surface F, and the posture can be particularly stabilized. .. In the present embodiment, the main body 11 itself has a difference in thickness in the front-rear direction, and the upper surface 11a and the lower surface 11b are angled. Therefore, even if the support tool 1 is used as the first embodiment S1, it corresponds to the angle. The effect of raising the back can be obtained.

Next, an example of the skeleton of the support tool 1 (the skeleton adopted in the sample shown in FIG. 3) will be described with reference to FIGS. 4 to 6. FIG. 4 is an overall configuration diagram of the skeleton of the sample, and FIG. 5 is a configuration diagram of a form in which the movable portion 30 is rotated in the skeleton. Further, FIG. 6 is a partially enlarged view of a main part (near the ratchet mechanism 40) of the frame.

As shown in these figures, the framework of the support tool 1 includes a rear rod-shaped portion 21 and a front rod-shaped portion 22 extending to the left and right, a right-side rod-shaped portion 23 and a left-side rod-shaped portion 24 extending to the front and back, a string-shaped body 25, and a movable portion. 30 and the ratchet mechanism 40 are used. The front, rear, left and right rod-shaped portions 21 to 24 are connected to each other so as to form a rectangular body, and are arranged in the vicinity of the lower surface 11b of the main body portion 11. The distance between the right-side rod-shaped portion 23 and the left-side rod-shaped portion 24 is substantially the same as the left-right dimension of the main body portion 11.

Further, inside the rectangular body, a plurality of string-shaped bodies 25 are provided on the left and right at substantially constant intervals so as to connect the rear-side rod-shaped portion 21 and the front-side rod-shaped portion 22, and the right-side rod-shaped portion 23 and the left-side rod-shaped portion 24 are provided. A plurality of string-like bodies 25 are provided in the front-rear direction at substantially constant intervals so as to connect the two. These string-shaped bodies 25 play a role of supporting the cushion material arranged on the upper side of the rectangular body.

A metal material is used for each of the rod-shaped portions 21 to 24 so that sufficient strength can be obtained, while a thin resin material is used for the string-shaped body 25, so that the weight of the support tool 1 can be reduced. Has been done. In the main body 11 of the sample shown in FIG. 3, a cushion material is mainly arranged on the upper side of the frame formed of the rod-shaped portions 21 to 24 and the string-shaped body 25, and the entire body is covered with a soft cover. It is formed.

Ratchet mechanisms 40 are provided at positions (positions corresponding to shafts 13) closer to the front side of each of the right side rod-shaped portion 23 and the left side rod-shaped portion 24, and movable portions 30 are connected to these left and right ratchet mechanisms 40. .. The movable portion 30 is formed by bending a rod-shaped body made of a metal material into a "U" shape, and one end is connected to the ratchet mechanism 40 on the right side and the other end is connected to the ratchet mechanism 40 on the left side. There is. The protruding portion 12 of the sample shown in FIG. 3 is formed so as to cover the movable portion 30 with a soft cover.

According to the support tool 1 formed by using the above-mentioned framework, when in use, the movable portion 30 extends in the left-right direction and the rear rod-shaped portion 21 (two rod-shaped portions separated from each other in the front-rear direction) is the base surface F. Supported by. Therefore, even if an unbalanced load is applied, the support tool 1 is prevented from tilting in the front-rear direction or the left-right direction as much as possible, and the posture can be stabilized and the support tool 1 can be used comfortably.

Further, regarding the specific configuration of the support tool 1, by providing a step on the lower surface 11b, the lower surface of the protruding portion 12 (the protruding portion 12 in the basic state) in the first embodiment S1 and the lower surface 11b of the main body 11 The rear side portion (the portion on the rear side of the shaft 13) may be included in the same plane. FIG. 7 shows a configuration example of the support tool 1 configured in this way from a side view. FIG. 7 (a) shows the case of the first form S1, and FIG. 7 (b) shows the case of the second form S2. Each case is shown. In this configuration example, a step is provided so that the front side portion of the lower surface 11b is located above the rear side portion, and the protrusion 12 in the basic state fits in the space of the step. Further, in this state, the positions of the front ends of the main body portion 11 and the protruding portion 12 in the front-rear direction are substantially the same.

According to the support tool 1, both the lower surface of the protrusion 12 and the rear portion of the lower surface 11b can be brought into contact with the flat base surface F in the first form S1, and the support tool 1 and the base surface F can be brought into contact with each other. The contact area of the support tool 1 can be made as large as possible to further stabilize the posture of the support tool 1, and it is possible to suppress a large local load from being applied to both the support tool 1 and the base surface F.

Next, a specific use example of the support tool 1 will be described with reference to FIGS. 8 to 10.

According to the usage examples shown in FIGS. 8 to 10, the mattress X2, the mattress Y2, or the bed pad Z3 is interposed between the user and the support tool 1, and the user keeps the sleeping posture with the upper body raised. You can sleep comfortably without worrying about the support tool 1. However, the usage pattern of the support tool 1 is not limited to the above example, and may be used in a form in which nothing is interposed between the user and the support tool 1.

As described above, the support tool 1 according to the present embodiment is a tool that is arranged on the base surface F such as the floor and supports the upper body of the lying user, and the upper body of the user with the head on the front side. It includes a main body portion 11 that receives the main body portion 11 and a protruding portion 12 that is movable with respect to the main body portion 11 and is provided so as to project from the main body portion 11. Further, the support tool 1 is arranged so that the rear end portion 11c of the main body portion 11 and the protrusion direction tip portion 12a of the protrusion portion 12 are supported by the base surface F, and the support angle θb can be adjusted by moving the protrusion portion 12.
