Description

本発明は、例えば車椅子の着座面や病院のベッドに載置され、着座者や患者に発生する褥瘡を防止するために用いられるクッションやマットレス等の支持具に関するものである。   The present invention relates to a support such as a cushion or a mattress that is placed on a seating surface of a wheelchair or a bed in a hospital and used to prevent pressure ulcers generated by a seated person or a patient.

一般に、この種の支持具としては、上方に向かって延びる袋状に形成された複数のエアーセルと、各エアーセルが水平方向に並設されるように各エアーセルの下端側を支持するベース部材と、各エアーセル内を互いに連通させるようにベース部材内に設けられた空気通路とを備え、各エアーセルによって任意の支持対象物を支持するようにしたものが知られている（例えば、特許文献１参照。）。
特表２００２−５０３１３６号公報 In general, as this type of support, a plurality of air cells formed in a bag shape extending upward, and a base member that supports the lower end side of each air cell so that each air cell is arranged in a horizontal direction, An air passage provided in a base member so as to communicate with each other in each air cell is provided, and an arbitrary support object is supported by each air cell (see, for example, Patent Document 1). ).
JP-T-2002-503136

ところで、前記支持具では、接着によって連結された上下２枚の平板状のゴムシートによってベース部材が構成され、上側ゴムシートは各エアーセルを下端が開口するように支持し、下側ゴムシートは上側ゴムシートの下面に接着によって連結されるとともに、各エアーセルの下端を閉鎖している。また、上側ゴムシートの下面と下側ゴムシートの上面とを一部非接着にするかチューブを埋設することにより前記空気通路が形成されている。   By the way, in the said support tool, a base member is comprised by the upper and lower two flat rubber sheets connected by adhesion | attachment, an upper rubber sheet supports each air cell so that a lower end may open, and a lower rubber sheet is an upper side. While being connected to the lower surface of the rubber sheet by adhesion, the lower end of each air cell is closed. The air passage is formed by partially unbonding the lower surface of the upper rubber sheet and the upper surface of the lower rubber sheet or by embedding a tube.

このため、非接着部によって空気通路を形成する場合は、例えば無用な接着剤によって空気通路用の非接着部分が接着されると、所望の空気通路が形成されないので、上側ゴムシートと下側ゴムシートとの接着による連結を正確に行う必要があり、また、チューブを埋設して空気通路を形成する場合は、チューブを所定位置に配置する作業が必要になり、上側ゴムシートと下側ゴムシートの連結作業が容易ではないという問題点があった。   For this reason, when the air passage is formed by the non-adhesive portion, for example, if the non-adhesive portion for the air passage is bonded with a useless adhesive, the desired air passage is not formed, so the upper rubber sheet and the lower rubber It is necessary to perform accurate connection with the sheet, and when the tube is embedded to form an air passage, it is necessary to place the tube at a predetermined position. The upper rubber sheet and the lower rubber sheet There has been a problem that the connecting work is not easy.

一方、各エアーセルをベース部材外に配置された複数のチューブによって連結し、各チューブによって空気通路を確保する場合もあるが、チューブが切断される可能性、複数のチューブを使用することによる部品点数の増大、連結部からの空気漏れの可能性、組立工数の増大等により、製造コストが高くつくという問題点があった。   On the other hand, there are cases where each air cell is connected by a plurality of tubes arranged outside the base member and an air passage is secured by each tube, but there is a possibility that the tube will be cut, the number of parts by using a plurality of tubes There is a problem that the manufacturing cost increases due to an increase in the number of parts, the possibility of air leakage from the connecting portion, an increase in the number of assembly steps, and the like.

本発明は前記問題点に鑑みてなされたものであり、その目的とするところは、各エアーセル内を互いに連通させる空気通路をベース部材に簡単且つ確実に形成することができ、しかも部品点数や組立工数の増大を招くことのない支持具を提供することにある。   The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to easily and surely form an air passage for communicating with each other in each air cell in the base member, and also to reduce the number of parts and assembly. An object of the present invention is to provide a support that does not increase man-hours.

上方に向かって延びる袋状に形成された複数のエアーセルと、各エアーセルが略水平方向に並設されるように各エアーセルの下端側を支持するベース部材と、ベース部材に設けられ、各エアーセル内を互いに連通させる空気通路とを備え、各エアーセルによって任意の支持対象物を支持する支持具において、前記ベース部材に、各エアーセルが略水平方向に並設されるように各エアーセルの下端側を支持する上側ベース部材と、上側ベース部材の下面に沿うように形成されるとともに上側ベース部材の下面に連結された下側ベース部材とを設け、上側ベース部材の下面または／及び下側ベース部材の上面に空気通路を構成する空気通路用溝を設けている。   A plurality of air cells formed in a bag shape extending upward, a base member that supports the lower end side of each air cell so that the air cells are arranged in a substantially horizontal direction, and provided in the base member. An air passage that allows the air cells to communicate with each other, and supports the lower end of each air cell so that each air cell is arranged in a substantially horizontal direction on the base member in a support device that supports an arbitrary support object by each air cell. And an upper base member formed along the lower surface of the upper base member and connected to the lower surface of the upper base member, the lower surface of the upper base member and / or the upper surface of the lower base member An air passage groove is provided in the air passage.

これにより、ベース部材には、各エアーセルが略水平方向に並設されるように各エアーセルの下端側を支持する上側ベース部材と、上側ベース部材の下面に沿うように形成されるとともに上側ベース部材の下面に連結された下側ベース部材とが設けられ、上側ベース部材の下面または／及び下側ベース部材の上面に空気通路を構成する空気通路用溝が設けられていることから、例えば上側ベース部材と下側ベース部材とを接着剤によって接着する場合でも、空気通路を構成する空気通路用溝が接着剤によって容易に閉鎖されることはない。また、空気通路用溝が空気通路を構成しているので、部品点数や組立工数の増大を招くことがない。   Thus, the base member is formed so as to be along the lower surface of the upper base member and the upper base member that supports the lower end side of each air cell so that the air cells are juxtaposed in a substantially horizontal direction. A lower base member connected to the lower surface of the upper base member, and an air passage groove that forms an air passage is provided on the lower surface of the upper base member and / or the upper surface of the lower base member. Even when the member and the lower base member are bonded to each other with an adhesive, the air passage groove constituting the air passage is not easily closed with the adhesive. Further, since the air passage groove constitutes the air passage, the number of parts and the number of assembling steps are not increased.

本発明によれば、上側ベース部材と下側ベース部材とを接着剤によって連結する場合でも、空気通路を構成する空気通路用溝が接着剤によって容易に閉鎖されることがないので、各エアーセル内を互いに連通させる空気通路をベース部材に簡単且つ確実に形成することができる。また、部品点数や組立工数の増大を招くことがないので、製造コストの低減を図る上で極めて有利である。   According to the present invention, even when the upper base member and the lower base member are connected by an adhesive, the air passage groove constituting the air passage is not easily closed by the adhesive. The air passages that communicate with each other can be easily and reliably formed in the base member. In addition, since the number of parts and the number of assembly steps are not increased, it is extremely advantageous in reducing the manufacturing cost.

When a seated person sits, the air in each air cell 10 circulates through the air passage groove 22a, and each air cell 10 The air pressure inside is adjusted. In addition, it is also possible to mount one support tool of this embodiment on the seating surface of a wheelchair, and it is also possible to mount a some support tool so that it may mutually align in a horizontal direction. In addition, the support of the present embodiment can be used as a mattress by placing it on a bed, and can also be used for other purposes. In addition, the number of each air cell 10 and the area of the base member 20 can be arbitrarily set according to a use.

このように、本実施形態によれば、ベース部材２０には上側ベース部材２１と下側ベース部材２２とが設けられ、上側ベース部材２１は各エアーセル１０が略水平方向に並設されるように各エアーセル１０の下端側を支持し、下側ベース部材２２は上側ベース部材２１の下面に沿うように形成され、上側ベース部材２１の下面に連結されている。また、各エアーセル１０内を互いに連通させる空気通路を構成する空気通路用溝２２ａが下側ベース部材２２の上面に設けられているので、例えば上側ベース部材２１の下面と下側ベース部材２２の上面とを連結を確実にするために接着剤で接着する場合でも、空気通路用溝２２ａが接着剤によって容易に閉鎖されることはなく、各エアーセル１０内を互いに連通させる空気通路をベース部材２０に簡単且つ確実に形成することができる。   Thus, according to the present embodiment, the base member 20 is provided with the upper base member 21 and the lower base member 22, and the upper base member 21 is configured so that the air cells 10 are arranged in parallel in a substantially horizontal direction. The lower base member 22 is formed along the lower surface of the upper base member 21, and is connected to the lower surface of the upper base member 21. Further, since air passage grooves 22a that constitute air passages that communicate with each other in the air cells 10 are provided on the upper surface of the lower base member 22, for example, the lower surface of the upper base member 21 and the upper surface of the lower base member 22 are provided. The air passage grooves 22a are not easily closed by the adhesive even when they are bonded with each other to ensure the connection, and the air passages that communicate with each other in the air cells 10 are formed in the base member 20. It can be formed easily and reliably.

また、空気通路用溝２２ａが空気通路を構成しているので、部品点数や組立工数の増大を招くことがなく、製造コストの低減を図る上で極めて有利である。さらに、空気通路用溝２２ａが下側ベース部材２２の上面に設けられていることから、金型で下側ベース部材２２を成形する際に空気通路用溝２２ａも同時に設けることができ、製造コストの低減を図る上でより有利である。   Further, since the air passage groove 22a constitutes an air passage, the number of parts and the number of assembly steps are not increased, which is extremely advantageous in reducing the manufacturing cost. Further, since the air passage groove 22a is provided on the upper surface of the lower base member 22, the air passage groove 22a can be provided at the same time when the lower base member 22 is formed with a mold, and the manufacturing cost is reduced. This is more advantageous in reducing the amount of the noise.

また、下側ベース部材２２の上面に係止突起２２ｂが設けられるとともに、上側ベース部材２１の下面に係止溝２１ｃが設けられ、係止突起２２ｂが係止溝２１ｃに上方から係止することにより上側ベース部材２１の下面に下側ベース部材２２が連結される。また、係止溝２１ｃが上側ベース部材２１の下面における係止突起２２ｂに対応する位置に設けられるとともに、係止突起２２ｂは空気通路用溝２２ａを囲むように設けられ、係止突起２２ｂは係止溝２１ｃに上方から係止する。このため、上側ベース部材２１と下側ベース部材２２とを連結すると、空気通路用溝２２ａによって構成される空気通路が係止溝２１ｃ及び係止突起２２ｂによってシールされ、空気通路からの空気漏れを防ぐことができる。   Further, a locking projection 22b is provided on the upper surface of the lower base member 22, a locking groove 21c is provided on the lower surface of the upper base member 21, and the locking projection 22b is locked to the locking groove 21c from above. Thus, the lower base member 22 is coupled to the lower surface of the upper base member 21. The locking groove 21c is provided at a position corresponding to the locking protrusion 22b on the lower surface of the upper base member 21, and the locking protrusion 22b is provided so as to surround the air passage groove 22a, and the locking protrusion 22b is engaged. It locks into the stop groove 21c from above. For this reason, when the upper base member 21 and the lower base member 22 are connected, the air passage constituted by the air passage groove 22a is sealed by the locking groove 21c and the locking projection 22b, and air leakage from the air passage is prevented. Can be prevented.

従って、係止溝２１ｃ及び係止突起２２ｂによって空気通路からの空気漏れを防ぐことができるので、上側ベース部材２１と下側ベース部材２２とを接着剤を用いずに連結することも可能となり、製造コストの低減を図る上で極めて有利である。   Therefore, since the air leakage from the air passage can be prevented by the locking groove 21c and the locking projection 22b, it is possible to connect the upper base member 21 and the lower base member 22 without using an adhesive, This is extremely advantageous in reducing the manufacturing cost.

一方、接着剤を用いて上側ベース部材２１と下側ベース部材２２とを連結する場合でも、下側ベース部材２２の全面に接着剤を塗布しないで係止突起２２ｂの部分のみに接着剤を塗布すれば、空気通路からの空気漏れを確実に防ぐことができるので、製造コストの低減を図る上で極めて有利である。   On the other hand, even when the upper base member 21 and the lower base member 22 are connected using an adhesive, the adhesive is applied only to the portion of the locking projection 22b without applying the adhesive to the entire surface of the lower base member 22. By doing so, it is possible to reliably prevent air leakage from the air passage, which is extremely advantageous in reducing the manufacturing cost.

尚、本実施形態では、下側ベース部材２２に図３に示す断面形状を有する係止突起２２ｂを設けたものを示したが、係止突起２２ｂを図７乃至図９に示す断面形状に形成することも可能である。この場合でも、係止突起２２ｂは下端側の幅寸法Ｌ１よりも上端側の幅寸法Ｌ２が大きくなるように形成されている。また、係止溝２１ｃは係止突起２２ｂに応じた形状にすることが好ましい。   In the present embodiment, the lower base member 22 is provided with the locking protrusion 22b having the cross-sectional shape shown in FIG. 3, but the locking protrusion 22b is formed in the cross-sectional shape shown in FIGS. It is also possible to do. Even in this case, the locking protrusion 22b is formed so that the width dimension L2 on the upper end side is larger than the width dimension L1 on the lower end side. The locking groove 21c is preferably shaped according to the locking projection 22b.

また、本実施形態では、図４に示すように、係止突起２２ｂが空気通路用溝２２ａの周縁に沿って延びるように形成されたものを示したが、図１０に示すように、空気通路用溝２２ａを囲むように係止突起２２ｂを形成することも可能である。   Further, in the present embodiment, as shown in FIG. 4, the locking projection 22b is formed so as to extend along the peripheral edge of the air passage groove 22a. However, as shown in FIG. It is also possible to form the locking protrusion 22b so as to surround the use groove 22a.

尚、本実施形態では、下側ベース部材２２の上面に係止突起２２ｂを設け、上側ベース部材２１の下面に係止溝２１ｃを設けたものを示したが、上側ベース部材２１の下面に係止突起を設け、下側ベース部材２２の上面に係止溝を設けることも可能である。この場合でも、上側ベース部材２１と下側ベース部材２２とを連結した際に、下側ベース部材２２に設けられた空気通路用溝２２ａが上側ベース部材２１に設けられた係止突起によって囲まれる。即ち、上側ベース部材２１に設けられた係止突起は下側ベース部材２２に設けられた空気通路用溝２２ａを囲むように形成されている。   In the present embodiment, the locking protrusion 22b is provided on the upper surface of the lower base member 22 and the locking groove 21c is provided on the lower surface of the upper base member 21, but the lower base member 22 is related to the lower surface of the upper base member 21. It is also possible to provide a stop projection and provide a locking groove on the upper surface of the lower base member 22. Even in this case, when the upper base member 21 and the lower base member 22 are connected, the air passage groove 22 a provided in the lower base member 22 is surrounded by the locking protrusion provided in the upper base member 21. . That is, the locking projection provided on the upper base member 21 is formed so as to surround the air passage groove 22 a provided on the lower base member 22.

また、本実施形態では、下側ベース部材２２の上面に空気通路用溝２２ａを設けたものを示したが、上側ベース部材２１の下面に空気通路用溝を設けることも可能であり、上側ベース部材２１の下面及び下側ベース部材２２の上面に空気通路用溝を設けることも可能である。   In the present embodiment, the air passage groove 22a is provided on the upper surface of the lower base member 22.
