【０００５】
【発明の実施の形態】
以下に、本発明のユニット部材の連結構造の好適実施例について図面を参照しながら説明する。
はじめに、この連結具で連結するユニット部材の一例について説明する。
図５および図６に示すユニット部材１は、本実施例の場合に硬質の合成樹脂材からなっており、平面矩形のプレートからなるベース面２上に略等間隔に柱状の筒部３を一連に複数突設した構造からなっている。
ここでユニット部材１の素材は、用途に応じて適宜変更することができ、金属製、陶磁性、その他適宜の素材を用いることができ、特に実施例に限定されるものではない。
【０００６】
そして、筒部３は、図示例の場合、ベース面２上に縦横３列、合計９個設けられており、ベース面２の底面で開口３ａして、頂部３ｂを閉塞した截頭円錐形状の筒部からなっている。
また筒部３の頂面に孔３ｃを設けてベース面２の裏面の下側の空気を筒部中空を介して上部（外部）へ放出しうるようにしてもよい。
また、このユニット部材１の縦横への連結手段として第１連結構成部と第２連結構成部が形成されている。
第１連結構成部は、縦横の一方（例えば横とする）の両端に設けられた係止受部４と係止突片５とからなっている。
【０００７】
この係止受部４は、図示例の場合に筒部３と略同じ高さ（必要に応じて筒部３より高くても低くても良い）で略山形状に折り返されて係止凹溝部４ａを形成している。
また、係止突片５は、上記係止凹溝部４ａ内に嵌合可能に僅かに後方へ傾斜する突出片からなっている。
【０００８】
従って、図８に示すように前後に連結されるユニット部材１の一方（後方）のユニット部材１の係止凹溝部４ａに他方（前方）のユニット部材の係止突片５を嵌合係止して連結する。
この連結に際して係止凹溝部５ａの隙間にシール部材Ｓを嵌着する等して、両ユニット部材の連結部分を密封するようにしてもよい。
なお、図示例の場合に上記係止凹溝部４ａが、やや後方へ傾斜した倒立断面略ＶまたはＵ字状の溝からなっているので、係止突片５を適宜傾斜させた状態で係合することができ、係止凹溝部の溝の厚みを係止突片の厚みよりもやや大きく設定することにより、設置面の傾斜や凹凸に合わせて多少撓ませて連結することができる。
【０００９】
次に、第２連結構成部は、図６に示すように、縦横の他方（例えば縦とする）の両端に設けられた凹溝部６ａを有する受部６と該凹溝部６ａに係合される突片７とからなっている。
従って、一方のユニット部材１の突片７を隣接する他方のユニット部材１の凹溝部６ａに嵌合係止して、縦方向に隣接するユニット部材相互を、隙間無く連結することができる。
ここで、突片は基板と段違い平行状で水平に突出されており、受部６はその凹溝部６ａに上記突片７が整合するよう水平に突出している。
【００１０】
これにより、左右方向に連結された多数のユニット部材は各ベース面２が一連に連続する面に設定され、連続するユニット部材の隙間が連通するので、左右方向に連続する一連の流路Ｌを形成することができる。
そして前後方向では、第１連結構成部４と５の係合個所が上記流路を形成する一連の周壁として機能する。
【００１１】
また、ユニット部材は、連結時に隙間無く連結されるので防水効果がある。
係合部分をシールすれば一層防水効果を高めることができる。
また、流路として使用しない場合でも、上記第１連結構成部が形成する周壁で囲まれた部分に砕石や土を入れ、植物を植えたり、芝生を植えたりすることができる。
従って、屋上等にこのユニット部材を連結して敷設すれば屋上庭園を造ることができる。
また瓦に代えて屋根材として屋根に葺いてもよい。
【００１２】
このように形成されるユニット部材１は、設置面に載置して使用に供されるが、設置面に固定したり、係止したりしてもよい。
固定方法としては設置面に接着剤を用いて接着する方法や固定ネジ、固定ボルトを使って固定する方法など、公知の固定手段を用いることができる。
【００１３】
上記のようなユニット部材１は、連結具により上下に連結される。
本実施例では、第１連結具１０を上下の連結用に用い、第２連結具２０と第３連結具３０とを補助に用いている。
ここで第１連結具１０では、図１および図２に示すように、中央に基板１１を有し、該基板１１の上面に第１係止突部１２を設け、基板１１の下面で第１係止突部１２と同軸線上に第２係止突部１５を突設した構成からなっている。
【００１４】
即ち、第１係止突部１２は、截頭円錐状からなっており、中央には穴部１３が形成されている。
図示例の場合、この第１係止突部１２は、ユニット部材１の筒部３の中空部に略隙間無く嵌合することができる外周形状からなっている。
この第１係止突部１２は、中実であってもよく、また長さは中空部の全長でなく中途位置まででもよい。その場合に第１係止突部１２は筒部３の内部中空の直径方向に略隙間無く嵌合可能な形状となっていればよい。
【００１５】
次に、第２係止突部１５は、前記筒部３に上から嵌め込まれ、この筒部３を直径方向に略隙間無く嵌合しうる大きさに設定された穴部１６を有する円筒形状からなっている。
即ち、第２係止突部１５は、穴部１６が、筒部３の上部形状に対応した截頭円錐形状の中空部からなっている。
従って、穴部１６には筒部３の上部を隙間無く嵌め込むことができる。
【００１６】
第２連結具２０は、図１および図３に示すように、中央にベース面２１を有し、該ベース面２１の上面に第１係止突部２２を設けた構成からなっている。
この第１係止突部２２は、前記第１連結部１０の第１係止突部１２とほぼ同様であって截頭円錐状からなっており、中央には穴部２３が形成されている。
そしてこの第１係止突部２２は、ユニット部材１の筒部３の中空部に略隙間無く嵌合することができる外周形状からなっている。
この第１係止突部２２も、中実であってもよく、また長さは中空部の全長でなく中途位置まででもよい。その場合に第１係止突部２２は筒部３の内部中空の直径方向に略隙間無く嵌合可能な形状となっていればよい。
また、設置面に載置するために扁平なベース面２１を用いたが、傾斜地などでは、基板の裏面に設置面に係止しうるような爪部を設けたり、あるいは設置面に貫入される杭部を設けたものであってもよい。
あるいは、基板そのものが杭状であってもよい。
【００１７】
第３連結具３０は、図１および図４に示すように、中央に基板３１を有し、該基板３１の下面に第２係止突部３２を設けた構成からなっている。
第２係止突部３５は、前記筒部３に上から嵌め込まれ、この筒部３を直径方向に略隙間無く嵌合しうる大きさに設定された穴部３６を有する円筒形状からなっている。
即ち、第２係止突部３５は、穴部３６が、筒部３の上部形状に対応した截頭円錐形状の中空部からなっている。
従って、穴部３６には筒部３の上部を隙間無く嵌め込むことができる。
【００１８】
この第１連結具１０は、上下に配置されたユニット部材を相互に連結する構造からなっているが、第２連結具２０は最下段に配置されたユニット部材１に係合し、第３連結具３０は最上段に配置されたユニット部材１に係合するようになっている。
従って、図１に示すように、上下多段にユニット部材が配置されたときに、所定の位置で上下に重なる筒部３を上記第１連結具１０、第２連結具２０、第３連結具３０を用いて係合することができる。
これにより、上記位置で同軸線上に並んだ筒部３、３、３は、第１連結具１０、第２連結具２０、第３連結具３０によって上下に拘束され連結される。
また上記縦に並んだ筒部３、３、３は第１〜第３連結具１０〜３０と一体になって、ユニット部材１を縦横且つ上下に連結して形成される構造体の柱部としてその強度を高めることができる。
また各第１〜第３連結具１０〜３０は、筒部３を介して相互に嵌合されるので、連結力を一層高めることができる。
【００１９】
このようにして、ユニット部材１は、縦または横方向および上下方向に連結して、一連の流路Ｌを形成することができる。
そして連結されたユニット部材は廃棄物の埋立地の底部に埋設されて、雨水などの排水を処理する構造としたり、地下の貯水部としたり、上下に積み重ねて通気部とする等種々に利用することができる。
また平面上に並べて、屋根材としたり、屋上の防水カバーとしたり種々の用途に用いることができる。
【００２０】
図７および図８は、上記各第１〜第３連結具１０、２０、３０をそれぞれ一体に複数連結した場合の異なる実施例を示す。
この実施例では、第１連結具１０が上記実施例の第１連結具と同一構成からなる連結部を４つ設けた構造からなっている。
そして各連結部の間隔は、ユニット部材１を連結した際の隣接するユニット部材１，１の隣接する筒部３、３間の間隔に合わせて設定しており、それらがプレート状の連設基板１１０により一体的に連設された構成からなっている。
このように第１連結具１０の各連結部は、隣接するユニット部材１の筒部３、３に跨って係合するように設定してあるので、上下と共に左右方向をも拘束することができる。
このように４つの連結部を設けた連結具は、図７に示すような４つのユニット部材のコーナーが接するクロス部分にそれぞれ１つづつ用いれば、全てのユニット部材を容易に連結することができる。
【００２１】
図７に一例を示すように、第１連結部１０が、縦横に連結された４つのユニット部材１で隣接する角部に配置された筒部３の間隔に合わせて４つ配置されており、それらが連設基板１１０により一体的に連設されているので、１つの第１連結具１０によって、上下各４枚のユニット部材を係止することができる。
第２連結部２０および第３連結部３０においても同様であって、第２連結部２０では、前記実施例の第２連結具と同一構成の連結部が連設ベース面２１０に４つ突設されており、第３連結部３０では、前記実施例の第３連結具と同一構成の連結部が連設基板３１０に４つ突設されている。
上記実施例ではコーナー部分の筒部を連結するために各連結部を４つ配置した構成を例示したが、２つ以上の連結部を設けるものであれば、その数は特に限定されるものではない。
ここで、各連結部は、前記実施例における第１連結具、第２連結具３０、第３連結具３０と同一構成であるのでその説明を省略する。
【００２２】
このように２つ以上の連結部を設けた場合に、隣接する筒部３に嵌合すると、第２係止突部の穴部１６、３３の周面がテーパ面となっており、また筒部３の外周面もテーパ面となっていることから、上記穴部と穴部の間隔を筒部と筒部の間隔よりも僅かに狭く設定しておけば、上記両方の筒部を接近方向に押し付けて連結することができる。
従って、図７で示したように隣接して係合するユニット部材１，１間に用いる連結部の間隔は、隣接するユニット部材でそれぞれ隣り合う筒部の間隔と同一ないし僅かに狭く設定しておくことが連結力を高めることができて好ましい。
【００２３】
上記実施例では、第１連結具１０と第２連結具２０と第３連結具３０を全て用いた場合を例示したが、第１連結具１０と第２連結具２０、または第１連結具と第３連結具３０を用いた場合であってもよい。
あるいは第１連結具１０だけを用いた構造であってもよい。
これらの場合に、補助的に用いる連結構造は特に限定されるものではない。
また、前記第１係止突部１２、２２は筒状からなるが、スリットを設けて拡縮可能とし拡大方向に弾性力が働く構成としてもよい。
前記第２係止突部１５、３２の筒部においても同様にスリットを設けて拡縮可能とし拡大方向に弾性力が働く構成としてもよい。
【００２４】
また、図示例ではユニット部材は筒部が上方へ延びる場合を例示したが、基板が起立しており筒部が横方向へ延びる場合には、連結具を横方向にして用いればよい。
またユニット部材の形状は実施例に限定されるものでないことは勿論であり、筒部が截頭円錐筒状に限らず、断面多角形や楕円形でもよく、要するに筒部が断面テーパ状の周壁を有するものであればよい。
そしてこの場合は、第１係止突部の外周壁や第２係止突部の穴部の形状は、上記筒部の外周形状に対応して筒部の直径方向に拘束しうるものであればよく、本実施例のような截頭円錐形状に限定されるものではない。
その他、要するにこの発明の要旨を変更しない範囲で種々設計変更しうる。
【００２５】
【発明の効果】
以上詳述した如く、本発明の連結具は、基板上に筒部を有する連結構成体を、その筒部を拘束して位置決めし、上下に配置された筒部を同時に係止することができるので、簡便に連結することができる。
また、筒部に連結具が嵌合されるので、筒部の強度を高めることができ、ユニット部材の支持力の向上を図ることができる。

[0005]
DETAILED DESCRIPTION OF THE INVENTION
In the following, preferred embodiments of the connecting structure for unit members of the present invention will be described with reference to the drawings.
First, an example of the unit member connected with this connector will be described.
The unit member 1 shown in FIGS. 5 and 6 is made of a hard synthetic resin material in the case of the present embodiment, and a series of columnar cylindrical portions 3 are arranged at substantially equal intervals on a base surface 2 made of a flat rectangular plate. It has a structure with multiple protrusions.
Here, the material of the unit member 1 can be appropriately changed according to the application, and metal, ceramics, and other appropriate materials can be used, and is not particularly limited to the embodiment.
[0006]
In the case of the illustrated example, the cylinder portion 3 is provided in a total of nine rows and columns on the base surface 2 in the form of a frustoconical shape having an opening 3a at the bottom surface of the base surface 2 and closing the top portion 3b. It consists of a cylinder.
Alternatively, a hole 3c may be provided on the top surface of the cylindrical portion 3 so that air below the back surface of the base surface 2 can be discharged to the upper part (outside) through the cylindrical portion hollow.
Moreover, the 1st connection structure part and the 2nd connection structure part are formed as a connection means to the vertical and horizontal of this unit member 1. As shown in FIG.
The 1st connection component consists of the latching receiving part 4 and the latching protrusion 5 which were provided in the both ends of vertical and horizontal (for example, let it be horizontal).
[0007]
In the case of the illustrated example, the latch receiving portion 4 is folded back into a substantially mountain shape at substantially the same height as the cylinder portion 3 (which may be higher or lower than the cylinder portion 3 as required). 4a is formed.
Moreover, the latching protrusion 5 consists of the protrusion piece which inclines slightly back so that it can fit in the said locking groove part 4a.
[0008]
Accordingly, as shown in FIG. 8, the locking protrusion 5 of the other (front) unit member is fitted and locked to the locking groove 4a of one (rear) unit member 1 of the unit members 1 connected back and forth. And connect.
At the time of this connection, the connecting portion of both unit members may be sealed by, for example, fitting the seal member S into the gap of the locking groove portion 5a.
In the case of the illustrated example, the engaging groove portion 4a is composed of a groove having an inverted cross section approximately V or U shape inclined slightly rearward, so that the engaging protrusion 5 is engaged in an appropriately inclined state. By setting the thickness of the groove of the locking concave groove portion to be slightly larger than the thickness of the locking protrusion, the connection can be made by being slightly bent according to the inclination or unevenness of the installation surface.
[0009]
Next, as shown in FIG. 6, the second connecting component is engaged with the receiving portion 6 having the recessed groove portions 6a provided at the other ends of the other of the vertical and horizontal sides (for example, vertical) and the recessed groove portions 6a. It consists of a projecting piece 7.
Accordingly, the projecting pieces 7 of one unit member 1 can be fitted and locked in the recessed groove portion 6a of the other unit member 1 adjacent to each other, so that the unit members adjacent in the vertical direction can be connected without a gap.
Here, the projecting piece protrudes horizontally in parallel with the substrate, and the receiving portion 6 projects horizontally so that the projecting piece 7 is aligned with the concave groove portion 6a.
[0010]
As a result, a large number of unit members connected in the left-right direction are set so that each base surface 2 is a continuous surface and the gaps between the continuous unit members communicate with each other. Can be formed.
In the front-rear direction, the engagement points of the first connection components 4 and 5 function as a series of peripheral walls that form the flow path.
[0011]
Further, since the unit members are connected without gaps when connected, there is a waterproof effect.
If the engagement portion is sealed, the waterproof effect can be further enhanced.
Moreover, even when not using as a flow path, a crushed stone and soil can be put into the part enclosed by the surrounding wall which the said 1st connection structure part forms, and a plant can be planted or a lawn can be planted.
Therefore, if this unit member is connected and laid on the rooftop or the like, a rooftop garden can be constructed.
Further, instead of tiles, the roof may be used as a roofing material.
[0012]
The unit member 1 formed in this way is placed on the installation surface for use, but may be fixed or locked to the installation surface.
As a fixing method, known fixing means such as a method of adhering to an installation surface using an adhesive, a method of fixing using a fixing screw or a fixing bolt can be used.
[0013]
The unit member 1 as described above is connected up and down by a connector.
In the present embodiment, the first connector 10 is used for upper and lower connections, and the second connector 20 and the third connector 30 are used for assistance.
Here, as shown in FIGS. 1 and 2, the first connector 10 has a substrate 11 at the center, a first locking protrusion 12 is provided on the upper surface of the substrate 11, and the first lower surface of the substrate 11 is the first. It has a configuration in which a second locking projection 15 is provided on the same axis as the locking projection 12.
[0014]
That is, the 1st latching protrusion 12 consists of truncated cone shape, and the hole 13 is formed in the center.
In the case of the illustrated example, the first locking protrusion 12 has an outer peripheral shape that can be fitted into the hollow portion of the cylindrical portion 3 of the unit member 1 without a substantial gap.
The first locking projection 12 may be solid, and the length may be up to the midway position instead of the full length of the hollow portion. In that case, the 1st latching protrusion 12 should just be a shape which can be fitted in the hollow direction inside hollow of the cylinder part 3 without a substantially clearance gap.
[0015]
Next, the second locking projection 15 is fitted into the cylindrical portion 3 from above, and has a cylindrical shape having a hole 16 that is set to a size that allows the cylindrical portion 3 to be fitted in the diametrical direction with almost no gap. It is made up of.
That is, the second locking projection 15 has a hole 16 formed of a frustoconical hollow portion corresponding to the upper shape of the cylindrical portion 3.
Therefore, the upper portion of the cylindrical portion 3 can be fitted into the hole portion 16 without a gap.
[0016]
As shown in FIGS. 1 and 3, the second connector 20 has a base surface 21 at the center and a first locking protrusion 22 provided on the upper surface of the base surface 21.
The first locking projection 22 is substantially the same as the first locking projection 12 of the first connecting portion 10 and has a frustoconical shape. A hole 23 is formed at the center. .
And this 1st latching protrusion 22 consists of the outer periphery shape which can be fitted in the hollow part of the cylinder part 3 of the unit member 1 without a substantially clearance gap.
The first locking protrusion 22 may also be solid, and the length may be up to the midway position instead of the full length of the hollow portion. In that case, the 1st latching protrusion 22 should just be a shape which can be fitted in the inside hollow diameter direction of the cylinder part 3 without a substantially clearance gap.
Further, the flat base surface 21 is used for mounting on the installation surface. However, on an inclined ground or the like, a claw portion that can be locked to the installation surface is provided on the back surface of the substrate, or the installation surface is penetrated. A pile portion may be provided.
Alternatively, the substrate itself may have a pile shape.
[0017]
As shown in FIGS. 1 and 4, the third connector 30 has a configuration in which a substrate 31 is provided at the center and a second locking projection 32 is provided on the lower surface of the substrate 31.
The second locking projection 35 is fitted into the cylindrical portion 3 from above, and has a cylindrical shape having a hole 36 that is set to a size that allows the cylindrical portion 3 to be fitted in the diameter direction without a substantial gap. Yes.
In other words, the second locking projection 35 has a hole portion 36 that is a frustoconical hollow portion corresponding to the upper shape of the cylindrical portion 3.
Therefore, the upper part of the cylinder part 3 can be fitted into the hole part 36 without a gap.

In this embodiment, the first connector 10 has a structure in which four connecting portions having the same configuration as the first connector of the above embodiment are provided.
And the interval of each connection part is set according to the space | interval between the adjacent cylinder parts 3 and 3 of the adjacent unit members 1 and 1 at the time of connecting the unit member 1, and these are plate-shaped connection boards. 110 is integrally connected by 110.
Thus, since each connection part of the 1st connection tool 10 is set so that it may straddle over the cylinder parts 3 and 3 of the adjacent unit member 1, it can restrain also the left-right direction with up-down. .
As shown in FIG. 7, all the unit members can be easily connected to each other by using one connecting portion provided with four connecting portions as shown in FIG. .
[0021]
As shown in an example in FIG. 7, four first connecting portions 10 are arranged in accordance with the interval between the cylindrical portions 3 arranged at the corner portions adjacent to each other by the four unit members 1 connected vertically and horizontally, Since they are integrally connected by the continuous substrate 110, each of the four upper and lower unit members can be locked by one first connector 10.
The same applies to the second connecting portion 20 and the third connecting portion 30. In the second connecting portion 20, four connecting portions having the same configuration as the second connecting tool of the above-described embodiment are provided on the continuous base surface 210. In the third connecting portion 30, four connecting portions having the same configuration as the third connecting tool of the above-described embodiment are provided on the continuous substrate 310.
In the above embodiment, the configuration in which four connecting portions are arranged in order to connect the cylindrical portions of the corner portions is illustrated, but the number is not particularly limited as long as two or more connecting portions are provided. Absent.
Here, since each connection part is the same structure as the 1st connection tool in the said Example, the 2nd connection tool 30, and the 3rd connection tool 30, the description is abbreviate | omitted.
[0022]
When two or more connecting portions are provided in this way, when fitted to the adjacent cylindrical portion 3, the peripheral surfaces of the holes 16 and 33 of the second locking projection are tapered, and the cylindrical portion Since the outer peripheral surface of the portion 3 is also a tapered surface, if the interval between the hole portion and the hole portion is set slightly narrower than the interval between the tube portion and the tube portion, both the tube portions are moved in the approach direction. Can be connected by pressing.
Accordingly, as shown in FIG. 7, the interval between the connecting portions used between the adjacent unit members 1 and 1 is set to be the same or slightly narrower than the interval between the adjacent cylindrical portions in the adjacent unit members. It is preferable that the connecting force can be increased.
[0023]
In the said Example, although the case where all the 1st connector 10, the 2nd connector 20, and the 3rd connector 30 were used was illustrated, the 1st connector 10, the 2nd connector 20, or the 1st connector The case where the 3rd connection tool 30 is used may be sufficient.
Or the structure using only the 1st coupling tool 10 may be sufficient.
In these cases, the auxiliary connection structure is not particularly limited.
Moreover, although the said 1st latching protrusions 12 and 22 consist of a cylinder shape, it is good also as a structure which provides a slit and can be expanded / contracted and an elastic force works in an expansion direction.
Similarly, the cylindrical portions of the second locking projections 15 and 32 may be provided with slits so that they can be expanded and contracted, and an elastic force acts in the expansion direction.
[0024]
Further, in the illustrated example, the case where the unit member extends the cylinder portion upward is illustrated, but when the substrate is erected and the tube portion extends in the lateral direction, the connecting member may be used in the lateral direction.
Of course, the shape of the unit member is not limited to the embodiment, and the cylindrical portion is not limited to the truncated conical cylindrical shape, and may be a polygonal or elliptical cross section. What is necessary is just to have.
In this case, the shape of the outer peripheral wall of the first locking projection and the hole of the second locking projection can be constrained in the diameter direction of the cylindrical portion corresponding to the outer peripheral shape of the cylindrical portion. What is necessary is just and it is not limited to the truncated cone shape like a present Example.
In addition, various design changes can be made without departing from the scope of the present invention.
[0025]
【The invention's effect】
As described above in detail, the connector of the present invention can position a connecting structure having a cylindrical portion on a substrate by restraining the cylindrical portion, and can simultaneously lock the cylindrical portions arranged vertically. Therefore, it can connect simply.
In addition, since the coupling tool is fitted to the tube portion, the strength of the tube portion can be increased and the support force of the unit member can be improved.
