Description

本発明は、第１の中空部材と、第１の中空部材の内側に配置される第２の中空部材とが相対移動可能な伸縮ユニット及びこの伸縮ユニットを用いて室内空間の広さを調整可能な建物ユニットに関する。   INDUSTRIAL APPLICABILITY The present invention provides a telescopic unit in which the first hollow member and the second hollow member disposed inside the first hollow member are relatively movable, and the size of the indoor space can be adjusted using the telescopic unit. Related to building units.

従来の種の伸縮ユニットとしては、例えば図８に示したように、中空部材からなる第１ユニット１と、この第1ユニット１内に挿入された第２ユニット２とからなり、第1ユニット１に対して第２ユニット２を伸縮可能としたものが知られている（特許文献１参照）。また、伸縮ユニットを用いた建物ユニットとしては、例えば図９に示したように、下端が下梁３に接続された第１小柱４と、上端が上梁５に接続された第２小柱６と、これら第１、第２小柱４，６に跨って配設され、いずれか一方の小柱に対して摺動自在とされる中間柱７とからなるものが知られている（特許文献２参照）。   As a conventional type of telescopic unit, for example, as shown in FIG. 8, the first unit 1 includes a first unit 1 made of a hollow member and a second unit 2 inserted into the first unit 1. On the other hand, what made the 2nd unit 2 extendable is known (refer patent document 1). Moreover, as a building unit using an expansion / contraction unit, for example, as shown in FIG. 9, the first small column 4 whose lower end is connected to the lower beam 3 and the second small column whose upper end is connected to the upper beam 5. 6 and an intermediate column 7 which is arranged across the first and second small columns 4 and 6 and is slidable with respect to any one of the small columns (patent) Reference 2).

しかしながら、上述した従来の伸縮ユニット及び建物ユニットにあっては、インナパイプとアウタパイプとを嵌め合わせただけのスライド構造であるため、例えばインナパイプを伸縮移動させる際にはアウタパイプとの間に発生する摩擦抵抗によってスムーズにスライド動作しないおそれがあった。特に、建物ユニットの柱に伸縮ユニットを用いる場合には、少なくとも部屋の四隅に配置した各柱を同時に且つ均等に伸縮させるのがきわめて困難であった。   However, since the conventional expansion unit and building unit described above have a slide structure in which the inner pipe and the outer pipe are simply fitted together, for example, when the inner pipe is expanded and contracted, it is generated between the outer pipe and the outer pipe. There was a risk that the sliding operation would not be smooth due to the frictional resistance. In particular, when an expansion / contraction unit is used as a pillar of a building unit, it is extremely difficult to extend / contract the pillars arranged at least at the four corners of the room simultaneously and evenly.

It is provided at a position coinciding with 31b. After the bolt insertion holes 37a and 37b of the second hollow member 11 are aligned with the bolt insertion holes 31a and 31b of the first hollow member 10, the bolts 34 are inserted, and the nuts 35 are tightened on the opposite side, whereby the second The hollow member 11 can be fixed in an extended state. The opening positions of the bolt insertion holes 37a and 37b are appropriately set depending on the extent to which the second hollow device 11 is extended by various devices using the extension unit S. The bolt insertion holes 37a and 37b are provided at one place when the second hollow member 11 is extended by one stage, and at a plurality of places when the second hollow member 11 is extended by a plurality of stages. The bolt insertion holes 33a and 33b in the upper position are for aligning and fixing the bolt insertion holes 31a and 31b of the first hollow member 10 when the second hollow member 11 is contracted. By this fixing, it is possible to prevent rattling during truck transportation.

なお、第１の中空部材１０の前側壁２１には、その上端近付近にストッパボルト３６が設けられている。このストッパボルト３６は、第２の中空部材１１を縮小させたときに、案内孔１９の上端１９ａに係止して第２の中空部材１１の落下を防ぐためのものである。   A stopper bolt 36 is provided in the vicinity of the upper end of the front side wall 21 of the first hollow member 10. The stopper bolt 36 is used to prevent the second hollow member 11 from falling by being locked to the upper end 19a of the guide hole 19 when the second hollow member 11 is contracted.

この実施例に係る伸縮ユニットＳは、図１乃至図３に示されるような振れ止め機構４０を備えている。この振れ止め機構４０は、第２の中空部材１１を伸縮させる際に、第２の中空部材１１に生じた振れを有効に防ぐためのものである。第２の中空部材１１の振れを左右から抑えるように、第１の中空部材１０の左右側壁３０ａ，３０ｂの上端部にそれぞれ設けられるのが望ましい。各振れ止め機構４０は、第１の中空部材１０に六角穴付きボルト４１で固定される固定ブロック４２と、この固定ブロック４２の内側面に設けられた凹部４３と、この凹部４３に嵌め込まれるホルダ４４と、このホルダ４４に凹設された湾曲部４５に転動可能に収容される円柱体４６とで構成される。また、固定ブロック４２には凹部４３の底面に貫通するネジ孔４７が設けられ、このネジ孔４７には円柱体４６の突出量を調整する手段として六角ネジ４８が螺合している。なお、固定ブロック４２の両側には六角穴付きボルト４１の挿通孔４９が３個ずつ設けられ、第１の中空部材１０の左右側壁３０ａ，３０ｂには対応するネジ孔５０が３個ずつ設けられている。前記円柱体４６はシリコン樹脂など摩擦係数の小さな材料からなり、第２の中空部材１１の外側面を転動する押当て部材である。   The telescopic unit S according to this embodiment is provided with a steadying mechanism 40 as shown in FIGS. The anti-sway mechanism 40 is for effectively preventing the shake generated in the second hollow member 11 when the second hollow member 11 is expanded and contracted. It is desirable that the second hollow member 11 is provided at the upper ends of the left and right side walls 30a and 30b of the first hollow member 10 so as to suppress the deflection of the second hollow member 11 from the left and right. Each steady stop mechanism 40 includes a fixed block 42 that is fixed to the first hollow member 10 with a hexagon socket head bolt 41, a recess 43 provided on the inner surface of the fixed block 42, and a holder that is fitted into the recess 43. 44 and a cylindrical body 46 that is accommodated in a curved portion 45 that is recessed in the holder 44 so as to be able to roll. Further, the fixing block 42 is provided with a screw hole 47 penetrating the bottom surface of the recess 43, and a hexagon screw 48 is screwed into the screw hole 47 as a means for adjusting the protruding amount of the cylindrical body 46. Three insertion holes 49 for the hexagon socket head cap bolt 41 are provided on both sides of the fixed block 42, and three corresponding screw holes 50 are provided on the left and right side walls 30a, 30b of the first hollow member 10. ing. The cylindrical body 46 is made of a material having a small friction coefficient such as silicon resin, and is a pressing member that rolls on the outer surface of the second hollow member 11.

図３には上記構成からなる振れ止め機構４０が第１の中空部材１０の左右側に一対配置された状態が示されている。このとき、円柱体４６は第２の中空部材１１の左右側壁３２ａ，３２ｂの外側面に押し当てられた状態にある。第２の中空部材１１を伸縮移動させると、円柱体４６は第２の中空部材１１の外側面に押し当てられた状態で外側面を転動し、第２の中空部材１１を両側から押さえ込むことで振れを有効に抑えることができる。なお、円柱体４６による押し当て力の調整は、固定ブロック４２の背面に突出する六角ネジ４８を回転させホルダ４４を押し出したり引っ込めたりすることによって、円柱体４６の突出量を調整することで行なわれる。また、円柱体４６が摩り減ったような場合には六角ネジ４８を調整することで、円柱体４６を適正な位置に押し出すことができる。   FIG. 3 shows a state in which a steady rest mechanism 40 having the above configuration is disposed on the left and right sides of the first hollow member 10. At this time, the cylindrical body 46 is pressed against the outer surfaces of the left and right side walls 32a and 32b of the second hollow member 11. When the second hollow member 11 is expanded and contracted, the cylindrical body 46 rolls on the outer surface while being pressed against the outer surface of the second hollow member 11, and presses the second hollow member 11 from both sides. This effectively suppresses the shake. The adjustment of the pressing force by the cylindrical body 46 is performed by adjusting the protruding amount of the cylindrical body 46 by rotating the hexagon screw 48 protruding to the back of the fixed block 42 to push out or retract the holder 44. It is. Further, when the cylindrical body 46 is worn out, the cylindrical body 46 can be pushed out to an appropriate position by adjusting the hexagon screw 48.

次に、上記構成からなる伸縮ユニットＳの作用について説明する。図２に示したように、第２の中空部材１１は、実線で示された位置が縮小した状態であり、仮想線で示された位置が伸張した状態である。第２の中空部材１１を伸張させる際には、第１の中空部材１２に固定された移動ブロック１５に対して、第２の中空部材１１に固定された軌道レールが転がり運動を伴って相対的に移動するため、第２の中空部材１１の動きはきわめてスムーズである。また、第１の中空部材１０と第２の中空部材１１との間に形成された隙間２０は、第２の中空部材１１が伸張する間、カラー２５によって確保されるために、第１の中空部材１０と第２の中空部材１１とが接触するなどして移動トラブルを起こすようなおそれもない。さらに、上記実施例の伸縮ユニットＳは左右一対の振れ止め機構４０を備えているので、第２の中空部材１１を伸張する際の振れも有効に抑えることができる。   Next, the operation of the telescopic unit S having the above configuration will be described. As shown in FIG. 2, the second hollow member 11 is in a state in which the position indicated by the solid line is reduced and the position indicated by the phantom line is extended. When the second hollow member 11 is extended, the track rail fixed to the second hollow member 11 is relative to the moving block 15 fixed to the first hollow member 12 with a rolling motion. Therefore, the movement of the second hollow member 11 is extremely smooth. In addition, the gap 20 formed between the first hollow member 10 and the second hollow member 11 is secured by the collar 25 while the second hollow member 11 extends, so that the first hollow There is no fear that the member 10 and the second hollow member 11 come into contact with each other to cause a movement trouble. Furthermore, since the expansion / contraction unit S of the said Example is equipped with the left-right paired steadying prevention mechanism 40, the vibration at the time of extending | stretching the 2nd hollow member 11 can also be suppressed effectively.

第２の中空部材１１を所定の高さ位置まで伸張させた後、第１の中空部材１０のボルト挿通孔３１ａ，３１ｂと第２の中空部材１１のボルト挿通孔３７ａ，３７ｂとを位置合せしてからボルト３４を挿通させ、反対側でナット３５締めすることで、図２及び図３に示したように第２の中空部材１１が第１の中空部材１０から伸びた状態で固定される。   After extending the second hollow member 11 to a predetermined height position, the bolt insertion holes 31a, 31b of the first hollow member 10 and the bolt insertion holes 37a, 37b of the second hollow member 11 are aligned. Then, the bolt 34 is inserted, and the nut 35 is tightened on the opposite side, whereby the second hollow member 11 is fixed in a state extending from the first hollow member 10 as shown in FIGS.

なお、上記実施例では第２の中空部材１１側を伸縮させる場合について説明したが、両部材は相対移動が可能な構成となっているので、第１の中空部材１０側を伸縮させることも可能である。また、上記の実施例では第１の中空部材１０と第２の中空部材１１とを１本ずつ設けた場合について説明したが、これら部材を複数本組み合わせて伸縮ユニットＳとして構成することも可能である。   In addition, although the said Example demonstrated the case where the 2nd hollow member 11 side was expanded-contracted, since both members become a structure which can be moved relatively, it is also possible to expand-contract the 1st hollow member 10 side. It is. In the above-described embodiment, the case where the first hollow member 10 and the second hollow member 11 are provided one by one has been described. However, a plurality of these members can be combined to form the expansion unit S. is there.

上記の伸縮ユニットＳは、後述する建物ユニットのみならず、住宅機器、オフィス機器、福祉機器などに用いられるスライド機構に幅広く利用することができる。   The telescopic unit S described above can be widely used not only for a building unit described later but also for a sliding mechanism used for housing equipment, office equipment, welfare equipment and the like.

次に、上記構成からなる伸縮ユニットＳを建物の柱などに応用した建物ユニットについて説明する。図６は伸縮ユニットＳを縮小させた時の建物ユニットＴを、図７は伸縮ユニットＳを伸張させた時の建物ユニットＴをそれぞれ示している。   Next, a building unit in which the telescopic unit S having the above configuration is applied to a pillar of a building will be described. 6 shows the building unit T when the telescopic unit S is contracted, and FIG. 7 shows the building unit T when the telescopic unit S is expanded.

この建物ユニットＴは、建物の４隅の柱に伸縮ユニットＳを用いており、伸縮ユニットＳの第１の中空部材をアウタ側の下柱６１として用い、第２の中空部材をインナ側の上柱６２として用いている。このように、伸縮ユニットＳを建物の柱として用いる場合には、下柱６１の下端は建物の床６３を構成するために配設される骨格部材としての下梁６４に固定され、上柱６２の上端は建物の天井６５を構成するために配設される骨格部材としての上梁６６に固定される。なお、伸縮ユニットＳの構成は既に説明してあるので、ここでは詳細な説明を省略する。   This building unit T uses the telescopic unit S for the pillars at the four corners of the building, uses the first hollow member of the telescopic unit S as the lower pillar 61 on the outer side, and the second hollow member on the inner side. It is used as the pillar 62. In this way, when the telescopic unit S is used as a building column, the lower end of the lower column 61 is fixed to the lower beam 64 as a skeleton member arranged to constitute the floor 63 of the building, and the upper column 62 Is fixed to an upper beam 66 as a skeleton member disposed to constitute the ceiling 65 of the building. In addition, since the structure of the expansion-contraction unit S has already been demonstrated, detailed description is abbreviate | omitted here.

この建物ユニットＴは、図６に示したように上柱６２を縮小した状態でトラックなどに積んで運搬される。このように建物ユニットＴの高さを抑えることで、一般のトラックによる運搬が可能となる。建物ユニットＴを建設場所まで運んだ後、図７に示したように上柱６２を伸ばして上梁６６を高くする。上柱６２を伸ばす作業はクレーンなどを用いて行なわれるが、建物ユニットＴの４隅の上柱６２を同時に且つ均等に引き上げる必要がある。この点、本発明では各柱が上記の伸縮ユニットＳによって構成されているので、４本の上柱６２をスムーズに且つ均等に引き上げることができる。即ち、上柱６２のスムーズな移動は、下柱６１と上柱６２との間に設けられた直線案内装置１２や位置規制部材としてのカラー２５、さらには振れ止め機構４０によって確保されることになる。   As shown in FIG. 6, the building unit T is carried on a truck or the like with the upper pillar 62 being reduced. By suppressing the height of the building unit T in this way, transportation by a general truck becomes possible. After the building unit T is carried to the construction site, the upper column 62 is extended and the upper beam 66 is raised as shown in FIG. The work of extending the upper column 62 is performed using a crane or the like. However, it is necessary to pull up the upper columns 62 at the four corners of the building unit T simultaneously and evenly. In this regard, in the present invention, each column is constituted by the above-described telescopic unit S, so that the four upper columns 62 can be pulled up smoothly and evenly. That is, smooth movement of the upper column 62 is ensured by the linear guide device 12 provided between the lower column 61 and the upper column 62, the collar 25 as a position restricting member, and the steadying mechanism 40. Become.

上柱６２を所定の高さ位置まで伸ばしたのち、各柱について下柱６１と上柱６２を締結ボルトで固定する。これにより建物ユニットＴの骨組み作業が完了する。そのあと、天井６５、間仕切り壁６７、外装壁６８、ドア６９、各種窓７０などの取り付けや、内装工事などを行なって建物が完成する。このようにして完成した建物ユニットＴは、天井６５が上柱６２の伸張分だけ高くなって室内空間が広くなるので、居住性の向上につながり、各種のプレハブ住宅、簡易型の店舗や事務所などに最適なものとなる。なお、建物ユニットＴを建設場所から撤去する場合には、天井６５や間仕切り壁６７などを外したのち、４隅の上柱６２を全て縮小させて図６に示したように下柱６１内に収容する。その状態でトラックに積み込み、次の建設場所まで運搬したのち、再び上述した天井を高くする作業を行なう。このように、本発明では建物ユニットＴを解体することなく、次の建設現場に運び込んで、そのまま再利用することができる。   After extending the upper column 62 to a predetermined height position, the lower column 61 and the upper column 62 are fixed with fastening bolts for each column. Thereby, the framework work of the building unit T is completed. After that, the building is completed by attaching the ceiling 65, the partition wall 67, the exterior wall 68, the door 69, various windows 70, etc., and interior work. The completed building unit T has a ceiling 65 that is higher by the extension of the upper pillar 62 and has a larger indoor space, leading to improved comfort and various prefabricated houses, simplified stores and offices. It will be the best for such. When the building unit T is removed from the construction site, the ceiling 65 and the partition wall 67 are removed, and then all the upper pillars 62 at the four corners are reduced and placed in the lower pillar 61 as shown in FIG. Accommodate. After loading in a truck in that state and transporting to the next construction site, the above-described work for raising the ceiling is performed again. Thus, in the present invention, the building unit T can be carried to the next construction site and reused as it is without dismantling.

なお、上記の建物ユニットＴにおいても、上柱６２に対して下柱６１の方を移動させてもよく、また下柱６１と上柱６２を複数本連結して一本の柱としてもよい。さらに、上記の建物ユニットＴでは伸縮ユニットＳを柱として利用した場合について説明したが、本発明では伸縮ユニットＳを横方向で伸縮するバー材として利用し、室内空間を横方向に広げ又は狭めることのできる建物ユニットにも適用することができる。   In the building unit T described above, the lower pillar 61 may be moved with respect to the upper pillar 62, or a plurality of lower pillars 61 and upper pillars 62 may be connected to form a single pillar. Further, in the building unit T described above, the case where the expansion / contraction unit S is used as a column has been described. It can also be applied to building units that can be used.
