請求項のネットスペーサは、嵌合凹部に抜け止め部を設けたことで、線材が嵌合部から外れることがなく、網目はネットスペーサにより安定して保持することができる。
According to the third aspect of the present invention, since the retaining portion is provided in the fitting concave portion, the wire does not come off from the fitting portion, and the mesh can be stably held by the net spacer.

以下、本発明のネットスペーサの実施形態について、図面に基づいて詳細に説明する。   Hereinafter, embodiments of the net spacer of the present invention will be described in detail with reference to the drawings.

図1は、実施例のネットスペーサ1の斜視図を示したものである。図2は、ネットスペーサ1の正面図である。図3は、ネットスペーサ1の側面図である。図4は、網目にネットスペーサ1を使用した状態の参考図である。   FIG. 1 is a perspective view of a net spacer 1 according to an embodiment. FIG. 2 is a front view of the net spacer 1. FIG. 3 is a side view of the net spacer 1. FIG. 4 is a reference diagram in a state where the net spacer 1 is used in the mesh.

ネットスペーサ1は、板体2,3を平面視十字状に結合して形成されている。板体2には、網目を受け嵌合凹部6に誘導するために円弧形状からなる誘導部4と、網目を固定する嵌合凹部6と、嵌合凹部6から網目が外れないように固定する抜け止め部5とが各々形成されている。   The net spacer 1 is formed by joining the plates 2 and 3 in a cross shape in plan view. In order to receive the mesh and guide it to the fitting recess 6, the plate member 2 is fixed so that the mesh is not removed from the guiding portion 4 having an arc shape, the fitting recess 6 for fixing the mesh, and the fitting recess 6. Each of the retaining portions 5 is formed.

一方、板体3は、脚8と網目を受ける係止部9とからなっている。そして、板体2の脚7と板体3の脚8とにより4方向で支えることで、倒れにくく安定性の高いネットスペーサとなっている。   On the other hand, the plate 3 is composed of legs 8 and locking portions 9 that receive the mesh. Further, by supporting in four directions by the legs 7 of the plate body 2 and the legs 8 of the plate body 3, it is a net spacer that is resistant to falling and has high stability.

そして、ネットスペーサ1の高さHは、法面から嵌合凹部6までの高さH1と、嵌合凹部6とつまみ10までの高さとからなる。したがって、高さH1によって法面から網目を浮かせる高さが決定する。   The height H of the net spacer 1 includes a height H1 from the slope to the fitting recess 6 and a height from the fitting recess 6 and the knob 10. Therefore, the height at which the mesh is lifted from the slope is determined by the height H1.

金網の網目の大きさをW1×W2とする。ネットスペーサ1は、左右の嵌合凹部6を繋ぐ距離がW1と同じである。板片3の左右の係止部9を繋ぐ距離は、W2と同じである。また、誘導部4,4の先端間の距離W3は、W1より長いことから網目を受けることが可能である。   The size of the wire mesh is W1 × W2. The distance between the left and right fitting recesses 6 of the net spacer 1 is the same as W1. The distance connecting the left and right engaging portions 9 of the plate piece 3 is the same as W2. Further, since the distance W3 between the tips of the guiding portions 4 and 4 is longer than W1, it is possible to receive a mesh.

また、ネットスペーサ1は、図5のような位置において網目の上から斜めに挿入するか、誘導部4に可撓性のある材質を用いることで上から押し込み、網目の下側へ通すことで設置可能となる。そして、ネットスペーサ1を持ち上げ、網目の一対の線材を誘導部4に沿って嵌合凹部6へ滑り込ませて2箇所で係止する。また、板体3の係止部9には、他の対の線材を係止させることにより安定した固定が行われる。   In addition, the net spacer 1 is installed by inserting it diagonally from above the mesh at a position as shown in FIG. 5 or by pushing in from the top by using a flexible material for the guide portion 4 and passing it through the bottom of the mesh. It becomes possible. Then, the net spacer 1 is lifted, and the pair of wires of the mesh is slid into the fitting recess 6 along the guide portion 4 and locked at two locations. Further, the fixing portion 9 of the plate body 3 is stably fixed by engaging another pair of wires.

上記の如く、ネットスペーサ1は、平面視十字状に結合される一対の板体2,3からなり、一方の板体2の上部には上部に金網の網目における平行な一対の線材が上方から嵌合可能な一対の嵌合凹部6と、その嵌合凹部6に夫々連設されて網目の外側に位置し、網目側への接近に従って嵌合凹部6へ夫々線材を誘導する一対の誘導部4とを備えている。
その結果、線材と嵌合凹部6との嵌合において、網目を下げるか、ネットスペーサ1自体を持ち上げることで、線材が板体2の誘導部4に沿って嵌合凹部6へ誘導され嵌合させることが容易にできる。
As described above, the net spacer 1 is composed of a pair of plates 2 and 3 coupled in a cross shape in plan view, and a pair of parallel wires in the mesh of the metal mesh is on the upper portion of one plate 2 from above. A pair of fitting recesses 6 that can be fitted, and a pair of guide portions that are respectively connected to the fitting recesses 6 and are located outside the mesh, and guide the wire to the fitting recesses 6 as they approach the mesh side. 4 is provided.
As a result, when the wire and the fitting recess 6 are fitted, the wire is guided to the fitting recess 6 along the guide portion 4 of the plate 2 by lowering the mesh or lifting the net spacer 1 itself. Can be easily done.

特に、板体2に嵌合凹部6を有し、対の線材と嵌合凹部6とが係止することと、板体3に係止部9を有し、他の対の線材と係止部9とが係止することと、その板体2,3を平面視十字状に結合することとにより、網目に対して安定した固定を行うことが可能となる。また、板体2の脚7と板体3の脚8とによって、平面視十字状に4箇所で法面を支持するので、1箇所で支持するものに比べ、倒れにくく安定性が高い。   In particular, the plate body 2 has a fitting recess 6 and the pair of wire rods and the fitting recess 6 are locked, and the plate body 3 has a locking portion 9 and locks with another pair of wire rods. By locking the portion 9 and connecting the plate bodies 2 and 3 in a cross shape in plan view, it is possible to perform stable fixing to the mesh. In addition, the leg 7 of the plate 2 and the leg 8 of the plate 3 support the slope at four locations in a cross shape in plan view, so that they are less likely to fall and more stable than those supported at one location.

また、誘導部4は、嵌合凹部6を最深部として外側へ行くに従って上昇する傾斜突片となっている。そのような傾斜突片によって、線材が誘導部4に沿って嵌合凹部6へ確実に誘導される。
また、嵌合凹部6に抜け止め部5を設けたことで、線材が嵌合部から外れることがなくなり、網目はネットスペーサ1により安定して保持することができる。
Moreover, the guide part 4 is an inclined protrusion that rises as it goes outward with the fitting recess 6 as the deepest part. With such an inclined protrusion, the wire is reliably guided along the guiding portion 4 to the fitting recess 6.
Further, by providing the retaining portion 5 in the fitting recess 6, the wire is not detached from the fitting portion, and the mesh can be stably held by the net spacer 1.

なお、本発明のネットスペーサの構成は、上記実施形態の態様に何ら限定されるものではなく、板体の形状、板厚、配置方法、嵌合凹部の形状、材質、構造等の構成を、本発明の趣旨を逸脱しない範囲で必要に応じて適宜変更することができる。   The configuration of the net spacer of the present invention is not limited to the aspect of the above embodiment, and the configuration of the shape of the plate, the plate thickness, the arrangement method, the shape of the fitting recess, the material, the structure, etc. The present invention can be changed as necessary without departing from the spirit of the present invention.

たとえば、ネットスペーサ1を構成する板体の数は、必要に応じて適宜変更することができる。また、実施例では、嵌合凹部6は板厚部分において網目と嵌合しているが、図6のように嵌合凹部6の肉厚を大きくしてもよい。この場合、嵌合凹部6において、線材に対して接地面積が増えることで、より強固な嵌合が可能となる。同様に、係止部9の肉厚を大きくしても良い。また、誘導部4の形状は、円弧を描いた形状を有しているが、使用状況に応じ、適宜変更しても良い。他には、板体3にも誘導部4を設けても良い。また、板体3の係止部9をなくして板体2の補助のみとして使用しても良い。   For example, the number of plates constituting the net spacer 1 can be appropriately changed as necessary. Moreover, in the Example, although the fitting recessed part 6 is fitted with the mesh | network in the plate | board thickness part, you may enlarge the thickness of the fitting recessed part 6 like FIG. In this case, in the fitting recess 6, the ground contact area increases with respect to the wire, so that a stronger fitting is possible. Similarly, the thickness of the locking portion 9 may be increased. Moreover, although the shape of the induction | guidance | derivation part 4 has the shape which drawn the circular arc, you may change suitably according to a use condition. In addition, the guide part 4 may be provided also in the plate body 3. Further, the locking portion 9 of the plate body 3 may be eliminated and the plate body 2 may be used only as an assist.
