本考案は設置や撤去作業が容易な、道路工事現場等における歩行用の組立式ゴムマットを提供せんとするものである。  The present invention is intended to provide an assembly-type rubber mat for walking on road construction sites and the like that can be easily installed and removed.

本考案は歩行用の組立式ゴムマットであって、円板状の連結盤（Ａ）と正三角形状の展開盤（Ｂ）とからなる。  The present invention is an assembly-type rubber mat for walking, and comprises a disk-shaped connecting board (A) and a regular triangular developing board (B).

連結盤Ａは、所定形状の円板１について、円板１と同一レベルの上面をなし厚さが円板１の３分の１で所定外径の円板部２と、円板１の円板部（２）以外を円環部３とするものとからなり、円板１は中心を通る垂直面で６等分されている各円弧区分４を左右均等な角度（α度）で縮小されて新規な円弧区分５が形成されるとともに挟角が２α度の第３の円弧区分６が形成されているものに対し、円弧区分５にあたる円環部３に対し厚さ３分の１の中間部位に、空洞部７を形成しており、円板部２の中心と、円弧区分５の中心線上の円環部３寄りにそれぞれ円環部３の下面のレベルに達する円柱突起８が垂下していて、これら両方の円柱突起８の中間に所定内径の円孔９が設けられていている。  The connecting board A is a disk 1 having a predetermined shape, having a top surface at the same level as that of the disk 1 and having a thickness of one third of the disk 1 and a predetermined outer diameter. The circular plate 3 is composed of the circular portion 3 other than the plate portion (2), and the circular plate 1 is reduced by an equal angle (α degrees) on each arc segment 4 divided into six equal parts by a vertical plane passing through the center. A new arc segment 5 and a third arc segment 6 with an included angle of 2α degrees are formed, and the intermediate thickness of the annular portion 3 corresponding to the arc segment 5 is one third of the thickness. A hollow portion 7 is formed in the part, and cylindrical protrusions 8 that respectively reach the level of the lower surface of the annular portion 3 hang down near the center of the circular portion 2 and the annular portion 3 on the center line of the arc segment 5. In addition, a circular hole 9 having a predetermined inner diameter is provided in the middle of both the cylindrical protrusions 8.

また、以上の連結盤Ａに組込まれる展開盤Ｂは、原型が円板１と同じ厚さで適宜大きさの正三角形とし、各頂角部１０が円弧区分５と合致する形状をしており、頂各部１０を除く正三角形の各辺が円弧区分４の両辺の延長と一致するようにしてあり、各頂角部１０の先端は円柱突起８の円柱面に当接するように湾曲しており、また、頂角部１０の中心線上に円柱突起８と嵌合する円孔１２が設けられており、ここにおける円柱突起８はその先端付近のみテーパを付して円孔１２を嵌合しやすくしてあるが、図面での記載は省略してある。なお、該正三角形の頂角部１０以外の上面に滑止用の溝１１を適宜設けてある。  Further, the unfolding board B incorporated in the connecting board A described above has a shape in which the prototype is an equilateral triangle having the same thickness as the disk 1 and an appropriate size, and each apex 10 matches the arc segment 5. The sides of the equilateral triangle excluding the apex portions 10 are made to coincide with the extension of both sides of the arc segment 4, and the tips of the apex corner portions 10 are curved so as to contact the cylindrical surface of the cylindrical projection 8. In addition, a circular hole 12 is provided on the center line of the apex portion 10 so as to be fitted to the cylindrical protrusion 8. The cylindrical protrusion 8 is tapered only near the tip of the circular protrusion 12 so that the circular hole 12 can be easily fitted. However, description in the drawings is omitted. A non-slip groove 11 is appropriately provided on the upper surface other than the apex portion 10 of the equilateral triangle.

さらに、連結盤Ａに対する展開盤Ｂの固定を強固にするため、展開盤Ｂの頂角部１０の上面の中心線上、円環部３と嵌合用円柱突起８の中間に、垂直断面が直角二等辺三角形をなす横長の展開盤Ｂ脱出防止用の小突起片があり、連結盤Ａの円板部２下面にそれを係止する凹陥溝を設けておくと好適である。  Further, in order to firmly fix the developing plate B to the connecting plate A, the vertical cross section is perpendicular to the center line of the top surface of the apex angle portion 10 of the developing plate B and between the annular portion 3 and the fitting cylindrical projection 8. It is preferable that there is a small projection piece for preventing escape of the horizontally long developing board B that forms an equilateral triangle, and that a concave groove for locking it is provided on the lower surface of the disk part 2 of the connecting board A.

そして、連結盤Ａに対する展開盤Ｂの嵌入による組立で、１個の連結盤Ａに６個の展開盤Ｂを挿入し、連結盤Ａの嵌合用円柱突起８に展開盤Ｂの円孔１２を嵌合し、必要に応じて、連結盤Ａの円板部２下面にある凹陥溝に、展開盤Ｂに設けてある展開盤Ｂ脱出防止用の小突起片を嵌入しておくとよい。連結盤Ａに対する展開盤Ｂの嵌入による組立が済んだならば、組立式ゴムマットの使用ができる。  Then, by assembling the expansion plate B into the connection plate A, six expansion plates B are inserted into one connection plate A, and the circular holes 12 of the expansion plate B are formed in the fitting column projections 8 of the connection plate A. It is good to fit the small protrusion piece for preventing the expansion | deployment board B escape provided in the expansion | deployment board B in the recessed groove in the disk part 2 lower surface of the connection board | substrate A as needed. When the assembly by inserting the development board B into the connection board A is completed, an assembly-type rubber mat can be used.

なお、本考案の組立式ゴムマットを撤去収納する場合は、使用状態のゴムマットの連結盤Ａの円孔９に手の指を差し込んで連結盤Ａから展開盤Ｂを外すようにし、ときには展開盤Ｂを少し押し下げて引き、展開盤Ｂ脱出防止用の小突起片を連結盤Ａの凹陥溝から外すことも必要になる場合がある。組立式ゴムマットの解体が済んだならば、円板状の連結盤Ａと正三角形状の展開盤Ｂをそれぞれ重ねて収納し、容易に運搬することができる。  When the assembly type rubber mat of the present invention is removed and stored, a finger is inserted into the circular hole 9 of the connecting plate A of the used rubber mat to remove the developing plate B from the connecting plate A, and sometimes the developing plate B It may be necessary to remove the small protrusion piece for preventing the unfolding of the developing plate B from the recessed groove of the connecting plate A by pushing down slightly and pulling. When the assembly type rubber mat is disassembled, the disk-like connecting board A and the equilateral triangle-like developing board B can be stored in a stacked manner and transported easily.

本考案の建設工事現場等における歩行者通路に使用する歩行用の組立式ゴムマットは設置や撤去作業が容易で、設置時の安定性がよく、収納時に嵩張らないので、広く用いられることが予測される。  Assembled rubber mats for walking used in pedestrian passages at construction sites etc. of the present invention are easy to install and remove, have good stability during installation and are not expected to be bulky during storage, and are expected to be widely used. The
