【自宅介助】 電動昇降座椅子を製作

まずは歩けない家族を自宅介助するにあたっての問題点の一つを記したい.

室内でも屋外でも電動車椅子を使うのは謂うまでもないのだが、問題は、
どうやって電動車椅子に乗せるのか
にある.
例えばベッド→電動車椅子への移動は、ぶっちゃけ「よっこいしょ」とやるのだが、この動作は上下動が無いので比較的容易である.母親であってもなんとか移動可能だ.

ところが、ベッド→電動車椅子へ移動させるときに母親がよろめいて、
被介助者を落としてしまう
コトがある.確率的には落としてしまうのは5%ぐらいだ.

そうやって母親が介助をする場面というのは、もちろんわたしが不在な場面であって、わたしが帰宅した時に被介助者がリビングの床で寝転がっていたりすると、「あぁまた落としたのだな」と判る.なぜなら被介助者を落としてしまうと、
床から車椅子までの約50cmの高度差をリフトアップするのは母親には不可能
だからである.すなわち落としてしまうと、
二人の人生はその場所で永遠にSTOP
してしまうのである.これが提起したい問題なのである.

わたしが日中不在であっても夕方帰宅ならばさしたる不具合ではないのだが、当ブログの読者ならご存知のようにどこかの地方へ旅に出て数日間不在になる場面がしばしばあるのがこのわたしというわけで、残された家族にとっては落下による人生停止問題はとてもリスキーなのだ.
↓死んだその場から移動できないのはまるで伊藤潤二の「墓標の町」状態であり、エイメンとしか言いようがない.
↓被介助者をリフトアップする「電動昇降座椅子」という介助器具が存在する.新品で16万円、中古で4万円ぐらいで買えるだろうか? 滅多に使わないわりに少々高価である.
だがこの「電動昇降座椅子」の致命的な問題は価格にあるのではない.その重量なのだ.写真の製品の重量は28kgと比較的軽量なのだが、一般的製品では45kgもある.2階建ての我が家において、45kgもの重量物を母親が階段で2階まで運ぶのはアリエナイ.28kgならまだしも可能性はあろうが、引きずって2階に上げるのが精一杯であろう.すなわち、
電動昇降座椅子それ自体が重量物なのでは本末転倒 (泣)
電動昇降車椅子の導入は意味を成さない.

↓やっぱ作るしかないなぁと思って誰でも想像するのがクルマのジャッキだよね.だがストロークが短いのと、人間をリフトアップするには横方向強度が不足と思われるので断念.
↓使えそうなのがこちら.バイクをリフトするジャッキだ.柱が2本なので横方向強度もなんとかなるかもしれない.価格は¥6000ぐらい、重量は15kg、ストロークは310mm
↓それでもって上下に板を装着し、座れるようにしたのがこちらの自家製「電動昇降座椅子」(総重量15.5kg)である.動力はインパクトドライバである.

↓着座後にはVP管で作った着脱可能な背もたれ・肘掛で落下しないようにする.背もたれ・肘掛を着脱可能にしてある理由は、被介助者を乗せる時点では四辺がフラットだと便利だから.インパクトドライバのおかげで70kgのわたしが座ってもちゃんと上昇する.
これで安心して地方巡業の旅に出れる.

webcam logicool C500のディスクリプタ

USBとかwebcamの制御に興味の無い人は読んでも無意味ですので、飛ばしてください.

webcam logicool C500のディスクリプタをtsharkで表示させましたら、とてつもなく長文なので構造がよくわかりませんで、う~んと考えて下記のような構造になっているようでした.
 ・前半がvideoで、後半がaudioに関するディスクリプタ
 ・解像度をいろいろと選択できる
 ・圧縮無しのYUVまたはMJPEGを選択できる
 ・たとえば、1280x720のMJPEGで撮影したいならば、
CONFIG(1)→INTERFACE(1)→ALTSETTING(0)→FORMAT(2)→FRAME(10)
  のように設定するのだと思うが、ではその他の選択肢であるところの、
CONFIG(1)→INTERFACE(1)→ALTSETTING(1)
  などにはどういう意味があるのか?それは謎のままです.

レインボーブリッジの上でエンストしたリード100は修理できたか?

昨日、レインボーブリッジの途中でエンストしたわたしのリード100.これはかつてのエゴバー、いまのジン&トニックのマスターからタラバガニとの物々交換で譲ってもらった由緒あるバイクなのです.

基本的には近所のバイク屋に入院させるつもりではあるのですが、素人でも可能な基本的な点検ぐらいはしておこうと思いまして.

↓サイドカバーはネジ3本で外せます.赤丸がキャブレターで、黄色丸がキャブのドレーンです.キャブのドレーンネジを回して、ガソリンがドレーンからぴゅーっと出ることを確認.燃料系の詰まりではないようでした.
↓次にシートを外しました.ネジ4本でパカッと外れちゃいます.エンジンを覗いて、オイルの飛び散りとかはありませんでした.
↓股の間、かかとの辺りにプラグの窓があります.プラグを外してみましたら、、、、
↓こんなに汚れたプラグは初めて見ました.ここまでなるまで動くんだからエンジンってすごいわ.これのどこに火花が飛んでいたのか不思議なくらいです.
ワイヤブラシでゴシゴシやりましたら、ハンダみたいな金属性の物質でスパークギャップがショートしてやがる.ひどいひどい.掃除したけれど、電極が磨り減っていて交換するべきと思いました.

とりあえずプラグを装着して、エンジンをかけたら、一発始動.修理代が浮いた.

近隣を少し走ったら全然問題なしでした.

#プラグは交換します

↓ちょっと高価なインジウムだかイリジウムを使ったプラグに交換しました.近頃のプラグは尖っているんですね.ポテンシャル勾配がキツくなっていい感じです.(NGK BPR6HIX)

【ヅガン】 レインボーブリッジの上でエンストしてみた

ビッグサイトで3Dプリンタの展示会があり見学しました.バイクで行ったんです.

往路で大井町の「牛八」に寄り、「スタミナカレー」を昼食としたのですが、サイズが(大)(中)(小)と3段階になっていました(かつては小と大).よくわからんので(中)をオーダーしたらあまりにも巨大で危うく残しそうになりました.牛八は(小)で十分だ.牛ゆう時代よりも味は劣化しました.
↓その後、3Dプリンタを見学しました.細いファイバーを積み上げるタイプが廉価モデルとして多く展示されていました.水平の筋が入るので仕上がりが悪くファイバー型を好きではありません.廉価で導入できる3Dプリンタでワクワクするのは無いな.

帰り道、レインボーブリッジの登りでバイクのエンジンパワーが低下してしまい、時速40kmしか出なくて後続のトラックに迷惑をかけてしまいました.芝浦側に差し掛かり下り坂になって再び速度が出たので後続のトラックを引き離しましたが、グルグル回る道のところでなんとエンスト!

↓振り返るとここですぜ.こんなところでエンストなんかしてどうすりゃいいの???
オーバーヒートかと思ってしばらく待ちましたがエンジンかからず.感覚的には、ガソリンコックを閉じたような止まりかただったので、説明書を読んだけどガソリンコックは在りません.

白バイが2度通りかかりましたけど、わたしを無視して過ぎ去りました.

結局バイクを押してレインボーブリッジを降りました.

「芝浦ふ頭駅」近隣のバイクショップを調べたけど無くて、北品川にならそれっぽい店があった.北品川だと遠回りなので、札の辻→高輪→白金→恵比寿→中目黒 と辿って、バイクを押して家まで歩いてしまいました.
星飛雄馬が重いコンダラで試練の道を歩んだように、わたしもバイクを押して試練の道を歩んだのでありました.
相当疲れましたぞ.おかげでスタミナカレー(中)の摂取カロリーは消費できたはずだった.

エイメン
