Description

本発明は、折り畳めば小型化出来るとともに開脚すれば椅子として活用出来て嵩張らず携行が容易な折り畳み椅子、および、椅子機能に付加して重量荷物等を持ち上げなくても移動することが出来る機能を有した嵩張らず携行が容易なキャスター付き折り畳み椅子、ならびに、前述の機能を有した嵩張らず携行が容易な折り畳み椅子付き鞄に関する。 The present invention is a folding chair that can be reduced in size when folded and can be used as a chair if it is opened, and is easy to carry without being bulky, and a function that can be moved without lifting heavy luggage etc. in addition to the chair function The present invention relates to a folding chair with casters that is easy to carry without being bulky, and a folding chair with folding chair that has the above-mentioned functions and is easy to carry without being bulky.

屋外において行動する場合において、途中で座りたくなる場合でも適当なベンチや椅子等が必ずしも近くに有るとは限らず、また、釣りやキャンプ等の屋外活動での腰掛けを必要とする場合を含めて、嵩張らず容易に持ち運べる簡易椅子の要望が有る。従来から、前述の要望に応えるいくつかの提案が既になされており、例えば、□型の部材を２個用いて中間部を回動可能に支承し脚部がＸ形状で上部側の腰掛け時の尻受け部に布状部材等を配設した簡易椅子が提案がなされ用いられて来ているが、□型部材を用いた簡易椅子では嵩張るという問題の解決策としては充分とは言えず、例えば、通勤・通学時等を含めた電車待ちやイベントでの順番待ち等で疲れていたり体調の変調を来し座りたくなっても其のために前述の□型部材を用いた簡易椅子を持ち運ぶことは負担感が大きく利用され難い。この様な要望を満たす提案として、例えば、非特許文献１，特許文献１等の様に、背負いの□型部材を用いた簡易椅子を付設したリュックサック、ナップサック等が提案され用いられて来てもいる。しかし、□型部材を用いた簡易椅子の嵩張るという短所は解消されていなく、背負い形態に留まっている様に見うけられる。また、別な観点から、例えば、特許文献２の様にステッキを利用した簡易組立椅子も提案されているが、ステッキは中高年や足等が不自由な人には必要であるが一般の通勤・通学者には必要が無く、また、非特許文献２，非特許文献３等の折り畳み傘の様な形態の折り畳み椅子も提案されているが、何れも携行が容易とは言い難く、前述の通勤・通学時等での座りたい要望への対応策としてわざわざ携行してその見返りの満足を得られる提案とは言い難いと考えられる。 Even if you want to sit outdoors, you may not always have a suitable bench or chair nearby, and you may need to sit in outdoor activities such as fishing or camping. There is a demand for a simple chair that can be easily carried without being bulky. Some proposals have been made to meet the above-mentioned demands. For example, when using two □ -shaped members, the middle part is pivotably supported, the leg part is X-shaped, and the upper side is when sitting on the upper side. A simple chair with a cloth-like member or the like arranged on the buttocks receiving portion has been proposed and used, but it cannot be said that it is sufficient as a solution to the problem that the simple chair using the □ -type member is bulky. Even if you are tired or want to sit down due to waiting for a train, commuting, attending school, etc. Is difficult to use because of the large burden. As proposals that satisfy such demands, for example, as in Non-Patent Document 1, Patent Document 1, etc., rucksacks, knapsacks, etc. with a simple chair using a □ -shaped member on the back have been proposed and used. There is also. However, the disadvantage of the bulkiness of the simple chair using the □ -type member has not been solved, and it seems that it remains in the backpack form. From another point of view, for example, a simple assembly chair using a walking stick as in Patent Document 2 has been proposed. The walking stick is necessary for people who are middle-aged or disabled, but can be used for general commuting. There is no need for commuters, and folding chairs in the form of folding umbrellas such as Non-Patent Literature 2 and Non-Patent Literature 3 have also been proposed, but it is difficult to say that they are easy to carry.・ It is difficult to say that it is a proposal that can be carried around to get the satisfaction of paying back as a response to the desire to sit at school.

一方、海外旅行や営業での資料・サンプル等の携行の場合には荷物が多くなり嵩張り重量化するため、これを容易に移動させる手段が欲しいとの要望がある。その手段として、例えば、非特許文献４、特許文献３、特許文献４、等の幾多の提案が既になされていて、取っ手が伸縮可能で比較的大きなキャスター付きの鞄・バック等が評価され広く利用されて来ている。また、前述の手段に類似したものでキャスターと荷物受けと取っ手の骨組み部だけで鞄・バック等を着脱可能とした用具も提案されている。しかし、前述の用途は荷物が嵩張り重量化することが明確である用途であるため、従来の提案の多くは鞄・バック自体が嵩張る形態であり、非特許文献５の様な鞄部を折り畳み式にした様な嵩張りの課題を改善する提案もなされているが、何れの提案も嵩張る形態であり、通勤・通学等で用いられる鞄・バック等の代替とはなり難いとともに簡易椅子としても利用し難いと考えられ、通常の通勤・通学時等での時間・順番待ち等で近辺に座れる適当なベンチや椅子が無いが座りたくて椅子が欲しいという場合の要望に対応出来る提案とは言い難いと考えられる。 On the other hand, in the case of carrying materials / samples for overseas travel or business, there is a demand for a means for easily moving the baggage because it increases the amount of luggage and makes it bulky. As its means, for example, a number of proposals such as Non-Patent Document 4, Patent Document 3, Patent Document 4, etc. have already been made, and the handle can be expanded and contracted, and a relatively large caster bag / back is evaluated and widely used. Have been. There has also been proposed a tool similar to the above-described means in which a bag, a bag, and the like can be attached and detached only by a caster, a luggage receiver, and a handle frame. However, since the above-mentioned application is an application in which it is clear that the baggage becomes bulky and heavy, many of the conventional proposals have a form in which the bag and the bag itself are bulky, and the hook part as in Non-Patent Document 5 is folded. There are proposals to improve the bulky problem as expressed in the formula, but each proposal is also a bulky form, and it is difficult to substitute for bags and bags used for commuting and attending school, and also as a simple chair It is difficult to use, and there are no suitable benches or chairs that can sit in the vicinity due to time and waiting time during normal commuting, attending school, etc. It seems difficult.

この様なことから、屋外において行動する場合で、通勤・通学時等を含めた電車待ちや何かのイベントでの順番待ち等で列を外れることが出来ないのに疲れていたり体調の変調を来し座りたくなる場合や、釣りやキャンプ等の屋外活動での腰掛けを必要とする場合を含めて、従来の簡易椅子の嵩張るため携行が容易でないという課題点が解決出来て嵩張らず小型化出来て容易に携行出来る簡易椅子が望まれていると考えられる。 Because of this, when you are acting outdoors, you may be tired or unable to change your physical condition even if you cannot wait for the train including commuting, attending school, or waiting for a turn at some event. It can solve the problem that it is not easy to carry because of the bulk of conventional simple chairs, including when you want to sit down and need to sit in outdoor activities such as fishing and camping. Therefore, a simple chair that can be carried easily is considered desirable.

また、当初は重量携行物は無く途中から重量携行物が生じる場合、若しくは、当初は重量携行物があり途中から重量携行物から解放される場合等で、重量携行物を持ち上げて運搬移動するのは苦痛を感じる場合に、持ち上げ運搬することなく転がし移動が出来るキャスター付き台車の代替が出来て其の目的が終了した場合には小型化出来て嵩張らず携行が容易な移動台車代替用具が望まれていると考えられる。

If you feel distress, you can replace a cart with casters that can be rolled and moved without lifting and transporting it. When the purpose is over, a mobile cart replacement tool that can be miniaturized and easy to carry without being bulky is desired. It is thought that.
