Description

本発明は、調整可能な多機能急速伸縮装置に関し、特に一体成型で、且つ、製造コスト及び労務費を節約でき、従って、多用途を具備する自由に急速昇降或いは伸縮できる調整可能な伸縮装置を提供することに関するものである。   The present invention relates to an adjustable multi-function rapid expansion / contraction device, and more particularly, to an adjustable expansion / contraction device that is integrally molded and that can save manufacturing costs and labor costs, and thus can be freely moved up and down or expanded and contracted freely. It is about providing.

例えば、２プレート間、２筒状物間、２管間、伸縮式三脚、伸縮式テーブル脚或いは折り畳み自転車などの一般的な伸縮可能な２物体の間において、摺動を防止するため、その伸縮はいずれもねじばね係止片又は嵌め輪を外付け、若しくは外枠を付加する方法により、２物体の間の高さ、長さの増減或いは固定することを実現してきた。   For example, in order to prevent sliding between two plates, between two cylindrical objects, between two tubes, two telescopic objects such as telescopic tripods, telescopic table legs or folding bicycles. In either case, the height and length between two objects have been increased or decreased or fixed by a method in which a screw spring locking piece or a fitting ring is externally attached or an outer frame is added.

例えば、現行の路面に用いるマンホール蓋は、蓋を嵌める方法で開口部を覆っているが、これでは高さを調整できない。これにより路面を補修する時、改めてアスファルトを舗装しなければならないため、補修した路面と既存の路面に段差が生じ、この段差が既存の路面より高くなる、または既存の路面より低くなる可能性がある。   For example, a manhole cover used for the current road surface covers the opening by a method of fitting the cover, but this cannot adjust the height. As a result, when repairing the road surface, the asphalt must be paved again, creating a step between the repaired road surface and the existing road surface, which may be higher than the existing road surface or lower than the existing road surface. is there.

この場合、一般的なマンホール蓋受枠では、高さを調整できないため、路面補修を完成した後もマンホール蓋と舗装した路面に段差が生じることにより、路面に不陸、凸起或いは凹み現象が生じる。この現象は、容易に道路利用者の安全上の危害を招き、特に、オートバイ又は自転車に搭乗する道路利用者にとって、安全上の更なる重大な危害となる。   In this case, since the height cannot be adjusted with a general manhole cover receiving frame, a level difference occurs between the manhole cover and the paved road surface even after completing the road surface repair, resulting in unevenness, protrusions or depressions on the road surface. . This phenomenon easily causes safety hazards for road users, and is a further serious safety hazard for road users riding motorcycles or bicycles in particular.

このため、現在の市場において、上述の問題を改善するため、高さを調整できるマンホール蓋受枠が市販されている。しかし従来の構造設計の構造は、いずれも極めて複雑であり、製造も不便で、且つ操作においても非常に困難であり、しかもその機能に制限があり、高さを速やかに微調整することができず、コストも比較的高くなる。   For this reason, in the current market, in order to improve the above-mentioned problem, a manhole cover receiving frame whose height can be adjusted is commercially available. However, the structures of the conventional structural design are all extremely complicated, inconvenient to manufacture, very difficult to operate, have limited functions, and can be finely adjusted in height quickly. In addition, the cost is relatively high.

上記の従来の問題点に鑑み、本発明の発明者は数年に渡り当該製品の研究、設計、製造などに従事することで豊富な経験を蓄積し、更に積極的に研究、創作に力を注ぐことで、ついに本発明の「調整可能な多機能急速伸縮装置」の開発に成功した。   In view of the above-mentioned conventional problems, the inventors of the present invention have accumulated abundant experience by engaging in research, design, manufacture, etc. of the product for several years, and more actively research and creation. By pouring, we finally succeeded in developing the “adjustable multi-function rapid expansion and contraction device” of the present invention.

本発明は、主に製造コスト及び労務費を節約でき、且つ諸多の伸縮が必要とする各種製品に運用でき、速やかに高さを微調整でき、或いは一体成型を兼用でき調整可能な多用途伸縮装置を提供することを目的とする。   The present invention mainly saves manufacturing costs and labor costs, and can be used for various products that require various expansion and contraction. An object is to provide an apparatus.

上述の目的を達成するため、本発明の調整可能な多機能急速伸縮装置には、一体成型できる外枠以及内枠を含み、その外枠と内枠の間において主にスロープ原理により昇降調節を行う係止突起の設計を利用して、その内枠が外枠内において速やかに微調整する昇降動作を行わせ、従って内枠が外枠内に高さの微調整効果を実現させる。
その他、本発明では現行のマンホール蓋受枠と組み合わせて使用することもでき、従って現行のマンホール蓋受枠の最も微小な変化を行うことで、本発明の調整可能な多機能急速伸縮装置を組み立てることができる。こうすることで、大幅にマンホール蓋受枠の取替コストを削減できるだけではなく、更に経済的便益を具備する速やかに調整可能な多用途伸縮装置を提供する。 In order to achieve the above-described object, the adjustable multi-function rapid expansion / contraction device of the present invention includes an outer frame that can be integrally molded and an inner frame, and the vertical adjustment is mainly performed between the outer frame and the inner frame by the slope principle. Utilizing the design of the locking projections to be performed, the inner frame performs a lifting operation in which fine adjustment is quickly performed in the outer frame, and thus the inner frame realizes a fine adjustment effect on the height in the outer frame.
In addition, in the present invention, it can be used in combination with the current manhole cover receiving frame. Therefore, by making the smallest change of the current manhole cover receiving frame, it is possible to assemble the adjustable multi-function rapid expansion and contraction device of the present invention. it can. In this way, not only can the manhole cover frame replacement cost be greatly reduced, but also a rapidly adjustable multipurpose telescopic device with further economic benefits.

以下、添付図面の実施形態により本発明の構造特徴及びその他作用、目的を詳細に説明する。   DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, structural features and other functions and objects of the present invention will be described in detail with reference to embodiments of the accompanying drawings.

（第１の実施形態）
まず、本発明の調整可能な多機能伸縮装置の第１の実施形態について、図１に図２及び図３を組み合わせてこれを参照にして説明する。該調整可能な伸縮装置には外枠１０及び内枠２０が含まれる。 (First embodiment)
First, a first embodiment of an adjustable multifunction expansion / contraction device of the present invention will be described with reference to FIG. 1 combined with FIG. 2 and FIG. The adjustable telescopic device includes an outer frame 10 and an inner frame 20.

外枠１０は、一体成型した中空管体で、且つ中空管体の内壁面１１に複数の内壁面１１から突出する第１係止部１２を設けた。図２を参照して説明し、該図は外枠１０の展開図で、第１係止部１２は下から上へ斜めに内壁面１１に配列し、外枠１０の実物において第１係止部１２の配列方式が螺旋状を呈する。   The outer frame 10 is an integrally molded hollow tube body, and a first locking portion 12 protruding from the plurality of inner wall surfaces 11 is provided on the inner wall surface 11 of the hollow tube body. 2, which is a developed view of the outer frame 10, and the first locking portions 12 are diagonally arranged on the inner wall surface 11 from the bottom to the top, and the first locking portion of the actual outer frame 10 is The arrangement system of the parts 12 exhibits a spiral shape.

内枠２０も一体成型で、外枠１０内部に収納でき、その内枠２０の側周壁２１に複数の第２係止部２２を設けた。図３を参照して説明し、該図は内枠２０の展開図で、第２係止部２２は下から上へ斜めに側壁周縁２１に配列し、内枠２０の実物において第２係止部２２の配列方式が螺旋状を呈する。該第２係止部２２と第１係止部１２が相互に対応し、且つ相互に係合できる。   The inner frame 20 is also integrally molded and can be stored inside the outer frame 10, and a plurality of second locking portions 22 are provided on the side peripheral wall 21 of the inner frame 20. Referring to FIG. 3, the drawing is a development view of the inner frame 20, and the second locking portions 22 are diagonally arranged from the bottom to the side wall peripheral edge 21, and the second locking portion is actually attached to the inner frame 20. The arrangement system of the parts 22 exhibits a spiral shape. The second locking portion 22 and the first locking portion 12 correspond to each other and can be engaged with each other.

次に、図４を参照して説明する。内枠２０を外枠１０内部に収納する時、内枠20と外枠１０は第１係止部１２と第２係止部２２の相互係合を通じて内枠２０と外枠１０の相対位置と相対高さを固定させることができる。そのほか、図５を参照して説明する。内枠２０と外枠１０の相対位置
が変位した時、第１係止部１２と異なる位置高さの第２係止部２２と相互に係合させることができる。これにより、内枠２０が外枠１０に相対的に微調整の昇降動作を発生できる。つまり内枠２０が外枠１０に相対的に回転すると、内枠２０が昇降動作を発生させることができる。 Next, a description will be given with reference to FIG. When the inner frame 20 is housed inside the outer frame 10, the inner frame 20 and the outer frame 10 are positioned relative to each other between the inner frame 20 and the outer frame 10 through mutual engagement of the first locking portion 12 and the second locking portion 22. The relative height can be fixed. In addition, it demonstrates with reference to FIG. When the relative position of the inner frame 20 and the outer frame 10 is displaced, the second locking portion 22 having a position height different from that of the first locking portion 12 can be engaged with each other. As a result, the inner frame 20 can generate a fine adjustment lifting operation relative to the outer frame 10. That is, when the inner frame 20 rotates relative to the outer frame 10, the inner frame 20 can generate a lifting operation.

第１係止部１２と第２係止部２２の形状は、四角形、歯形、円弧形とすることができ、第１係止部１２と第２係止部２２の相互係合条件を満たすことができる状態で、任意の幾何形状はいずれも適用できる。   The shapes of the first locking portion 12 and the second locking portion 22 can be quadrangular, tooth-shaped, arc-shaped, and satisfy the mutual engagement condition of the first locking portion 12 and the second locking portion 22. Any arbitrary geometric shape can be applied.

（第２の実施形態）
次に、本発明の調整可能な多機能伸縮装置の第２の実施形態について、図６を参照して説明する。隣接する第１係止部１２の間に適当な間隔を有することができる。隣接する第２係止部２２の間に適当な間隔も有することができ、隣接する第１係止部１２の間隔が第２係止部２２の寸法より大きくさせ、隣接する第２係止部２２の間隔が第１係止部１２の寸法より大きくさせる。この設計は外枠１０と内枠２０を組み立てる時、第１係止部１２が隣接する第２係止部２２の隙間を直接通過させることができる。相対的に第２係止部２２が隣接する第１係止部１２の隙間も直接通過でき、任意の２組の係止部の間隔はまたも該係止部の寸法より大きいため、外枠１０と内枠２０は急速に所要の相対的高さ位置に組み立てた後、対応回転して第１係止部１２と第２係止部２２を相互に係合させると、組み立て又は調整を完了できる。且つ第１係止部１２と第２係止部２２は、直角三角形を形成する時、第３係止部３２と第４係止部３３は斜辺が逆となる直角三角形を形成し、こうすることで１つの反力を発生して外枠１０と内枠２０間の移動を制止できるよう安定力を発生させることで、いかなるアクセサリーも要せず、固定させることができる。 (Second Embodiment)
Next, 2nd Embodiment of the multifunctional expansion-contraction apparatus which can be adjusted of this invention is described with reference to FIG. An appropriate interval can be provided between the adjacent first locking portions 12. There can also be an appropriate interval between the adjacent second locking portions 22, and the interval between the adjacent first locking portions 12 is made larger than the size of the second locking portion 22, so that the adjacent second locking portions 22 The interval of 22 is made larger than the dimension of the 1st latching | locking part 12. FIG. In this design, when the outer frame 10 and the inner frame 20 are assembled, the first locking portion 12 can directly pass through the gap between the adjacent second locking portions 22. Since the second locking portion 22 can pass directly through the gap between the adjacent first locking portions 12 and the interval between any two sets of locking portions is again larger than the size of the locking portion, the outer frame 10 and the inner frame 20 are rapidly assembled to the required relative height positions and then rotated correspondingly to engage the first locking portion 12 and the second locking portion 22 to complete the assembly or adjustment. it can. In addition, when the first locking portion 12 and the second locking portion 22 form a right triangle, the third locking portion 32 and the fourth locking portion 33 form a right triangle whose hypotenuses are opposite to each other. Thus, by generating one reaction force and generating a stabilizing force so that the movement between the outer frame 10 and the inner frame 20 can be stopped, it is possible to fix without requiring any accessories.

（第３の実施形態）
次に、本発明の調整可能な多機能伸縮装置の第３の実施形態について、図７を参照して説明する。本発明を現行の丸形マンホール蓋の構造に応用した時、該内枠２０の内壁面に複数の第２係止部２２を設けてスロープ状になり、その頂上部が内枠２０の適正高さを超えず、また水や泥の浸入を防止するため、内枠側周壁２１にワッシャーを設置して遮蔽壁になる。 (Third embodiment)
Next, a third embodiment of the adjustable multifunction telescopic device of the present invention will be described with reference to FIG. When the present invention is applied to the structure of the current round manhole cover, a plurality of second locking portions 22 are provided on the inner wall surface of the inner frame 20 to form a slope, and the top of the inner frame 20 has an appropriate height. In order to prevent the water and mud from entering, a washer is provided on the inner frame side peripheral wall 21 to form a shielding wall.

また外枠１０の内壁１１に複数の単体第１係止部１２を設け、内壁の上に固定させ、その頂上部の高さも内枠２０の適切な高さを超えず、第２係止部２２と対応させるようになっている。   Further, a plurality of single first locking portions 12 are provided on the inner wall 11 of the outer frame 10 and fixed on the inner wall, and the height of the top does not exceed the appropriate height of the inner frame 20, and the second locking portion 22 is made to correspond.

高さを調整する時、内枠２０を嵩上げて左右に少し回転するだけで、第１、第２係止部位置の変化によって内枠２０の外枠１０高さに対応する昇降を発生でき、この時両係止部の高さがわずかマンホール高さの半分或いは以下になったため、その上部は密封状態を維持できることで、水や泥の浸入を防止できる。その側壁及びその受け座にもう１つのワッシャー１３を設けると、騒音の防止及び密封の目的を達成できる。同時に図１６を参照して説明する。本発明は、第１係止部１２のうちのいずれか又は複数の高さをアップすることで、マンホール３０に傾斜を発生させて地表面の勾配に合わせることができ、巨額の労務費及びコストをかけて特殊な傾斜できるマンホールに交換する必要がなく、従って二酸化炭素削減の環境保全という目的を達成できる。   When adjusting the height, the inner frame 20 can be raised and raised slightly corresponding to the height of the outer frame 10 of the inner frame 20 by changing the position of the first and second locking portions by slightly rotating left and right. At this time, since the height of both locking portions is slightly less than or equal to half the manhole height, the upper portion can be kept in a sealed state, thereby preventing water and mud from entering. If another washer 13 is provided on the side wall and the receiving seat, the purpose of noise prevention and sealing can be achieved. At the same time, description will be made with reference to FIG. In the present invention, by increasing the height of one or more of the first locking portions 12, the manhole 30 can be inclined to match the gradient of the ground surface, resulting in huge labor costs and costs. Therefore, it is not necessary to replace the manhole with a special inclination, so that it is possible to achieve the objective of environmental conservation by reducing carbon dioxide.

図８を参照して説明する。本発明をマンホール蓋体３０の構造に実施し、実際に応用する時、マンホール蓋体３０の上面と路面４０を面一となるようにしなければならず、同時にその段差の許容誤差が一定の範囲を超えてはならない。路面４０を補修、再舗装する時（図９に示す）、新路面４０’とマンホール蓋体３０の段差が往々にして許容誤差値を超える。この際、内枠２０を嵩上げて蓋体３０の上面と新路面４０’を同じ高さにし、並びに第１係止部１２と第２係止部２２の係合、固定を通じて蓋体３０を新路面４０’と同じ高さの位置に固定できる。   This will be described with reference to FIG. When the present invention is applied to the structure of the manhole cover 30 and actually applied, the upper surface of the manhole cover 30 and the road surface 40 must be flush with each other, and at the same time, the tolerance of the step is within a certain range. Must not be exceeded. When the road surface 40 is repaired and re-paved (shown in FIG. 9), the step between the new road surface 40 'and the manhole cover 30 often exceeds an allowable error value. At this time, the inner frame 20 is raised so that the upper surface of the lid 30 and the new road surface 40 ′ are at the same height, and the lid 30 is renewed through engagement and fixation of the first locking portion 12 and the second locking portion 22. It can be fixed at the same height as the road surface 40 '.

簡易な回転動作を通じて、急速に昇降の微調整作業を行うことができ、並びに現行のマンホール蓋を本発明と組み合わせて使用でき、従って微調整が可能で且つ速やかに調整できるマンホール蓋の構造を実現でき、新しいマンホール蓋に交換する必要がない。   Through simple rotation operation, it is possible to perform fine adjustment work of raising and lowering rapidly, and the current manhole cover can be used in combination with the present invention, thus realizing a manhole cover structure that can be finely adjusted and adjusted quickly. Yes, there is no need to replace it with a new manhole cover.

（第４の実施形態）
次に、本発明の調整可能な多機能伸縮装置の第４の実施形態の内枠２０が外枠１０に昇降動作を行う断面動作見取図について、図１０Ａ乃至図１０Ｃを参照して説明する。図に示すように、該第１係止部１２と第２係止部２２は、他の実施形態で呈し、主に該第１係止部１２がのこぎり歯形形状の設計を呈し、該第２係止部２２も第１係止部１２と対応するのこぎり歯形形状の設計を呈し、且つ第３係止部３２と第４係止部３３上ののこぎり歯形形状の設計は逆方向配列設計を呈し、こうすることで第１、と第２係止部に反力を発生して摺動を防止し、またマンホール蓋受枠の内枠２０が微調整の昇降動作を発生させることができ、つまり第１係止部１２と第２係止部２２の相互噛合を介して、モノレール式係止突起を形成でき、従って位置決め効果を実現する。特に該第１係止部１２と第２係止部２２はいずれもスロープ状の構造を呈し、そのマンホール受座の内枠２０が回転方法によりマンホール受座の外枠１０内部において微調整の昇降動作を実現させることができる。 (Fourth embodiment)
Next, a sectional operation sketch in which the inner frame 20 of the fourth embodiment of the adjustable multi-functional telescopic device of the present invention moves up and down on the outer frame 10 will be described with reference to FIGS. 10A to 10C. As shown in the figure, the first locking portion 12 and the second locking portion 22 are present in other embodiments, and the first locking portion 12 mainly has a sawtooth shape design, and the second The locking portion 22 also has a saw tooth shape design corresponding to the first locking portion 12, and the saw tooth shape design on the third locking portion 32 and the fourth locking portion 33 has a reverse arrangement design. In this way, reaction force is generated in the first and second locking portions to prevent sliding, and the inner frame 20 of the manhole cover receiving frame can generate a fine adjustment lifting / lowering operation. A monorail type locking projection can be formed through the mutual engagement of the first locking portion 12 and the second locking portion 22, thus realizing a positioning effect. In particular, the first locking portion 12 and the second locking portion 22 both have a slope-like structure, and the inner frame 20 of the manhole seat is moved up and down by fine adjustment within the outer frame 10 of the manhole seat by the rotation method. Operation can be realized.

第２係止部２２の高さは全壁体の適正高さを超えず、その上部に遮蔽壁２６を構成し外枠１０間と密封状態になると、水や泥の浸入を防止できる。   The height of the second locking portion 22 does not exceed the appropriate height of the entire wall body. If the shielding wall 26 is formed on the upper portion and the space between the outer frames 10 is sealed, water and mud can be prevented from entering.

図１０Ａに示すように、該第１係止部１２と第２係止部２２は完全に噛み合う時、そのマンホール蓋体３０とマンホール受座の外枠１０及びマンホール受座の内枠２０が面一となる。 As shown in FIG. 10A, when the first locking portion 12 and the second locking portion 22 are completely engaged, the manhole cover body 30, the outer frame 10 of the manhole seat, and the inner frame 20 of the manhole seat face.
