また、フロアマット22の傾斜面部22Bは、図7に示すように、足乗せ部9の平板部9A(フロアマット22の底面)に対し傾斜角αをもって傾斜している。この傾斜面部22Bの傾斜角αは、その上面がマット挟持部26の上面板26Bの開口側に対し傷付かないように徐々に当接し、足乗せ部9との間にしっかりと挟まれるような角度に設定されている。また、傾斜面部22Bは、靴に付着した泥が乗車時に最も付着する部分であるが、外側に向けて低くなるように傾斜することで、泥を自動的に排出でき、または容易に掃き出すことができる。   Further, the inclined surface portion 22B of the floor mat 22 is inclined at an inclination angle α with respect to the flat plate portion 9A (the bottom surface of the floor mat 22) of the footrest portion 9, as shown in FIG. The inclination angle α of the inclined surface portion 22B is such that the upper surface of the inclined surface portion 22B gradually comes into contact with the opening side of the upper surface plate 26B of the mat holding portion 26 so as not to be damaged, and is firmly sandwiched between the footrest portion 9. It is set to an angle. Further, the inclined surface portion 22B is a portion where mud adhering to the shoe adheres most when getting on, but by inclining so as to become lower toward the outside, the mud can be automatically discharged or easily swept out. it can.

さらに、フロアマット22は、例えば足乗せ部9の収容凹部9Cに収容される工具の出し入れ、空調ユニットの室内機のメンテナンス等を容易に行うことができるように、取付け、取外しが困難な後述のペダル側マット23と別個に形成されている。これにより、フロアマット22は、左側の端部を滑止め部材24のマット挟持部26から引出すだけで、容易に剥がし取ることができ、また差し込むだけで容易に敷設することができる。   Furthermore, the floor mat 22 is difficult to attach and detach, which will be described later, so that, for example, the tool accommodated in the accommodating recess 9C of the footrest 9 can be easily taken in and out and the indoor unit of the air conditioning unit can be easily maintained. It is formed separately from the pedal side mat 23. Thereby, the floor mat 22 can be easily peeled off simply by pulling out the left end portion from the mat holding portion 26 of the non-slip member 24, and can be easily laid simply by being inserted.

23はフロアマット22の前側に位置してフロア部材8のレバー・ペダル取付部10に敷設されたペダル側マットである(図2参照)。このペダル側マット23は、フロアマット22とほぼ同様に、弾性を有する樹脂材料、ゴム材料等を用いて左,右方向に細長い長方形状に形成されている。   Reference numeral 23 denotes a pedal-side mat positioned on the front side of the floor mat 22 and laid on the lever / pedal mounting portion 10 of the floor member 8 (see FIG. 2).

Further, the non-slip member 24 has a function of holding the floor mat 22 in a positioning state on the footrest portion 9 of the floor member 8. As shown in FIGS. 8 and 9, the non-slip member 24 is generally constituted by a footrest plate part 25, a mat holding part 26, and a non-slip protrusion 27 described later.

25は滑止め部材24のベースとなる足掛け板部である。この足掛け板部25は、オペレータが乗降するときに足を掛けるもので、例えば前,後方向に延びる略長方形状の金属製の板体として形成されている。また、足掛け板部25は、足乗せ部9の左端に沿うように前,後方向に延び長方形状の平面部25Aと、該平面部25Aの右前側に位置してフロア部材8の足乗せ部9に取付けられる前側取付部25Bと、前記平面部25Aの右後側に位置して足乗せ部9に取付けられる後側取付部25Cと、前側取付部25Bの左側に位置して前記平面部25Aから下向きに屈曲した前側折曲部25Dと、後側取付部25Cの左側に位置して前記平面部25Aから下向きに屈曲した後側折曲部25Eと、前記各取付部25B,25Cから下向きに突出するようにそれぞれ固着されたボルト25Fと、前記各折曲部25D,25Eの近傍に位置して平面部25Aの下面に固着されたナット25Gとにより構成されている。   Reference numeral 25 denotes a footrest plate portion serving as a base of the non-slip member 24. This footrest plate portion 25 is used when an operator gets on and off, and is formed, for example, as a substantially rectangular metal plate extending in the front and rear directions. Further, the footrest plate portion 25 extends in the front and rear directions along the left end of the footrest portion 9 and has a rectangular flat surface portion 25A and a footrest portion of the floor member 8 that is positioned on the right front side of the flat surface portion 25A. 9, a front mounting portion 25B mounted on the right side of the flat portion 25A, a rear mounting portion 25C mounted on the footrest portion 9 and a left side of the front mounting portion 25B. A front bent portion 25D bent downward, a rear bent portion 25E located on the left side of the rear mounting portion 25C and bent downward from the flat surface portion 25A, and downward from the mounting portions 25B and 25C. The bolt 25F is fixed so as to protrude, and the nut 25G is positioned near the bent portions 25D and 25E and fixed to the lower surface of the flat portion 25A.

一方、各折曲部25D,25Eは、平面部25Aの前,後の端縁から下側に折曲げることにより形成されている。そして、下側に折曲げてなる各折曲部25D,25Eは、図6に示す如く、足乗せ部9の側板部9Bに当接することができ、足掛け板部25の踏付け強度を高めることができる。さらに、各ナット25Gには、外装カバー19のサイドカバー19Dを取付けるためのボルト21が螺着される。   On the other hand, the bent portions 25D and 25E are formed by bending downward from the front and rear edges of the flat portion 25A. And each bending part 25D, 25E bent downward can contact | abut to the side plate part 9B of the footrest part 9, as shown in FIG. 6, and raises the stepping strength of the footrest board part 25. Can do. Further, a bolt 21 for attaching the side cover 19D of the exterior cover 19 is screwed to each nut 25G.

26は足掛け板部25に設けられたマット挟持部で、該マット挟持部26は、前側取付部25Bと後側取付部25Cとの間に位置して平面部25Aの右側に設けられている。このマット挟持部26は、フロアマット22の乗降口12側の端部となる傾斜面部22Bを、フロア部材8を構成する足乗せ部9の平板部9Aとの間で上,下方向に挟んで保持するものである。また、マット挟持部26は、足掛け板部25と一緒に切出された金属製の板体に所定の曲げ加工を施すことにより、該足掛け板部25と一体形成されている。   Reference numeral 26 denotes a mat holding portion provided in the footrest plate portion 25. The mat holding portion 26 is provided between the front mounting portion 25B and the rear mounting portion 25C and is provided on the right side of the flat surface portion 25A. The mat sandwiching portion 26 sandwiches an inclined surface portion 22B, which is an end portion of the floor mat 22 on the entrance 12 side, with the flat plate portion 9A of the footrest portion 9 constituting the floor member 8 in the upward and downward directions. It is to hold. The mat sandwiching portion 26 is integrally formed with the footrest plate portion 25 by subjecting a metal plate cut out together with the footrest plate portion 25 to a predetermined bending process.

そして、マット挟持部26は、図6、図7に示す如く、前,後の取付部25B,25Cの間に位置して、平面部25Aのフロアマット22側となる右側の端部から上方に立上がると共に右側に延びて形成されている。即ち、マット挟持部26は、平面部25Aの右端部から右斜め上方に立上がった斜面板26Aと、該斜面板26Aの先端からフロアマット22に向け右側に延びた上面板26Bとにより、右側に向けて開口するように形成されている。   As shown in FIGS. 6 and 7, the mat sandwiching portion 26 is located between the front and rear mounting portions 25B and 25C and extends upward from the right end on the floor mat 22 side of the flat portion 25A. It is formed so as to rise and to the right. That is, the mat sandwiching portion 26 includes a slope plate 26A that rises obliquely upward to the right from the right end portion of the flat portion 25A and an upper surface plate 26B that extends to the right from the tip of the slope plate 26A toward the floor mat 22. It is formed so that it may open toward.

ここで、図7に示すように、フロアマット22の傾斜面部22Bの傾斜角をα度とし、マット挟持部26の上面板26Bの傾斜角をβ度とすると、このマット挟持部26の上面板26Bの傾斜角βは、フロアマット22の傾斜面部22Bの傾斜角αよりも小さな値に設定されている(β<α)。これにより、マット挟持部26の上面板26Bは、開口側から奥所の斜面板26Aに向け傾斜することにより、上面板26Bの開口側を広くすることができ、フロアマット22の端部をスムーズに差し込むことができる。   Here, as shown in FIG. 7, when the inclination angle of the inclined surface portion 22B of the floor mat 22 is α degrees and the inclination angle of the upper surface plate 26B of the mat holding portion 26 is β degrees, the upper surface plate of the mat holding portion 26 The inclination angle β of 26B is set to a value smaller than the inclination angle α of the inclined surface portion 22B of the floor mat 22 (β <α). Accordingly, the upper surface plate 26B of the mat sandwiching portion 26 can be inclined from the opening side toward the inclined plate 26A in the back, so that the opening side of the upper surface plate 26B can be widened, and the end portion of the floor mat 22 can be made smooth. Can be plugged into.

しかも、上面板26Bは、フロアマット22の傾斜面部22Bの傾斜角αよりも小さな傾斜角βをもって開口側から奥所に向け傾斜しているから、フロアマット22の端部を所定寸法差し込んだ位置で、上面板26Bの開口側をフロアマット22の傾斜面部22Bの上面に当接させることができる。これにより、マット挟持部26の上面板26Bは、フロアマット22の傾斜面部22Bをフロア部材8の足乗せ部9との間で挟んで保持することができ、フロアマット22の位置ずれ、めくれ上がり等を防止することができる。   Moreover, since the upper surface plate 26B is inclined from the opening side toward the back with an inclination angle β smaller than the inclination angle α of the inclined surface portion 22B of the floor mat 22, the end portion of the floor mat 22 is inserted at a predetermined dimension. Thus, the opening side of the upper surface plate 26B can be brought into contact with the upper surface of the inclined surface portion 22B of the floor mat 22. As a result, the upper surface plate 26B of the mat holding portion 26 can hold the inclined surface portion 22B of the floor mat 22 with the footrest portion 9 of the floor member 8, and the floor mat 22 is displaced and turned up. Etc. can be prevented.

27は足掛け板部25の平面部25Aに設けられた複数個の滑止め突起で、該各滑止め突起27は、平面部25Aから上向きに突出することにより、靴底に係合して乗降時の足の滑りを防止するものである。そして、各滑止め突起27は、図6等に示す如く、平面部25Aから上向きに突出した円柱状のピン部材27Aと、該ピン部材27Aの下部に拡径して設けられ、平面部25Aの下面に溶接された円板状の取付板27Bとにより構成されている。   Reference numeral 27 denotes a plurality of non-slip projections provided on the flat surface portion 25A of the footrest plate portion 25. Each of the anti-slip projections 27 protrudes upward from the flat surface portion 25A, thereby engaging the shoe sole when getting on and off. This prevents slipping of the foot. As shown in FIG. 6 and the like, each of the anti-slip protrusions 27 is provided with a cylindrical pin member 27A projecting upward from the flat surface portion 25A, and with an enlarged diameter at the lower portion of the pin member 27A. It is comprised by the disk-shaped attachment board 27B welded to the lower surface.

ここで、滑止め突起27は、図5、図8に示す如く、前,後方向に並べて配置された複数個を1列とし、この1列目の右側に間隔をもって前,後方向にずらした状態で2列目を配置している。これにより、各滑止め突起27は、広い範囲で足の滑りを防止できる上に、1列目、2列目で各滑止め突起27を前,後方向にずらして配設しているから、少ない本数で効率よく滑りを止めることができる。   Here, as shown in FIG. 5 and FIG. 8, the anti-slip protrusion 27 is arranged in a row with a plurality arranged in the front and rear directions, and is shifted in the front and rear directions with an interval on the right side of the first row. The second row is arranged in the state. Accordingly, each of the anti-slip protrusions 27 can prevent slipping of the foot in a wide range, and the anti-slip protrusions 27 are arranged to be shifted in the front and rear directions in the first and second rows. Slip can be stopped efficiently with a small number.

このように構成された滑止め部材24は、図4、図6に示すように、足掛け板部25の各ボルト25Fをフロア部材8を構成する足乗せ部9の挿通孔9Eに挿通し、ボルト25Fの先端にナット28を螺着することにより、前記足乗せ部9の乗降口12側に取付けることができる。そして、滑止め部材24を足乗せ部9に取付けた状態では、足乗せ部9の平板部9Aとマット挟持部26の上面板26Bとの間で、フロアマット22の左端部(傾斜面部22B)を挟んで保持することができる。   As shown in FIGS. 4 and 6, the non-slip member 24 configured as described above is configured such that each bolt 25 </ b> F of the footrest plate portion 25 is inserted into the insertion hole 9 </ b> E of the footrest portion 9 constituting the floor member 8. By screwing a nut 28 to the tip of 25F, the footrest 9 can be attached to the entrance 12 side. And in the state which attached the non-slip | skid member 24 to the footrest part 9, between the flat plate part 9A of the footrest part 9, and the upper surface board 26B of the mat clamping part 26, the left end part (inclined surface part 22B) of the floor mat 22 is provided. Can be held.

そこで、フロア部材8の足乗せ部9上にフロアマット22を敷設する場合には、このフロアマット22の乗降口12側の端部となる傾斜面部22Bを足乗せ部9の平板部9Aとマット挟持部26の上面板26Bとの間に差し入れるだけで、足乗せ部9とマット挟持部26との間にフロアマット22の傾斜面部22Bを挟んで保持することができる。このように、足乗せ部9とマット挟持部26との間にフロアマット22の傾斜面部22Bを挟んで保持した場合、この傾斜面部22Bとの間には隙間がないから、フロアマット22の端部は、足乗せ部9とマット挟持部26との間で振動することもなく、摩擦力の働きによって前,後方向に動くこともできない。   Therefore, when the floor mat 22 is laid on the footrest portion 9 of the floor member 8, the flat surface portion 9A of the footrest portion 9 and the mat are provided with the inclined surface portion 22B which is the end portion of the floor mat 22 on the entrance / exit 12 side. The inclined surface portion 22B of the floor mat 22 can be sandwiched and held between the footrest portion 9 and the mat sandwiching portion 26 simply by being inserted between the upper surface plate 26B of the sandwiching portion 26. Thus, when the inclined surface portion 22B of the floor mat 22 is sandwiched and held between the footrest portion 9 and the mat holding portion 26, there is no gap between the inclined surface portion 22B. The part does not vibrate between the footrest part 9 and the mat holding part 26, and cannot move forward and backward by the action of frictional force.

一方、フロア部材8の足乗せ部9からフロアマット22を取外す場合には、フロアマット22の傾斜面部22Bは、フロアマット22自体の弾性力でマット挟持部26に向け押付けているだけであるから、フロアマット22の傾斜面部22を足乗せ部9とマット挟持部26との間から引抜くだけで、簡単に取外すことができる。   On the other hand, when the floor mat 22 is removed from the footrest portion 9 of the floor member 8, the inclined surface portion 22B of the floor mat 22 is simply pressed against the mat holding portion 26 by the elastic force of the floor mat 22 itself. The inclined surface portion 22 of the floor mat 22 can be easily removed simply by pulling it out between the footrest portion 9 and the mat holding portion 26.

本実施の形態による油圧ショベル1は上述の如き構成を有するもので、次に、その動作について説明する。   The hydraulic excavator 1 according to the present embodiment has the above-described configuration, and the operation thereof will be described next.

まず、フロア部材8に乗り込む場合に、オペレータは、乗降口12が設けられた上部旋回体3の左側に位置して下部走行体2の履帯2C上に乗り、この履帯2C上からフロア部材8の足乗せ部9上に乗り込んで運転席13に着座する。このときに、オペレータは、乗降口12を通る自然な乗降動作の中でフロア部材8の左側に設けられた滑止め部材24に足を掛ける。この滑止め部材24には、複数個の滑止め突起27を設けているから、オペレータは、各滑止め突起27に靴底を係合させることにより、足を滑らせることなくフロア部材8上に乗り込むことができる。また、フロア部材8から足を滑らせることなく降りることもできる。   First, when getting on the floor member 8, the operator gets on the crawler belt 2C of the lower traveling body 2 and is located on the left side of the upper swing body 3 provided with the entrance 12 and from the crawler belt 2C, Get on the footrest 9 and sit on the driver's seat 13. At this time, the operator puts his / her foot on the non-slip member 24 provided on the left side of the floor member 8 in a natural getting-on / off operation through the entrance 12. Since the anti-slip member 24 is provided with a plurality of anti-slip protrusions 27, the operator engages the shoe soles with the anti-slip protrusions 27 so that the foot does not slide on the floor member 8. I can get in. It is also possible to get off the floor member 8 without sliding the foot.

そして、運転席13に着座したオペレータは、走行用レバー・ペダル14を操作することにより、下部走行体2を走行させることができる。また、作業用レバー16を操作することにより、作業装置4を俯仰動させて土砂の掘削作業等を行うことができる。   The operator seated in the driver's seat 13 can drive the lower traveling body 2 by operating the traveling lever / pedal 14. Further, by operating the working lever 16, the working device 4 can be moved up and down to perform excavation work of earth and sand.

かくして、本実施の形態によれば、フロア部材8の乗降口12側の端部に設けた滑止め部材24には、フロアマット22の乗降口12側の端部となる傾斜面部22Bをフロア部材8の足乗せ部9との間で上,下方向に挟んで保持するマット挟持部26を設ける構成としている。これにより、前記足乗せ部9上にフロアマット22を敷設するときには、フロアマット22の傾斜面部22Bを足乗せ部9と滑止め部材24のマット挟持部26との間に差し込むだけで、フロアマット22の傾斜面部22Bを、足乗せ部9と滑止め部材24のマット挟持部26との間で上,下方向に挟んで保持することができる。   Thus, according to the present embodiment, the non-slip member 24 provided at the end portion on the entrance / exit 12 side of the floor member 8 is provided with the inclined surface portion 22B serving as the end portion on the entrance / exit 12 side of the floor mat 22. A mat sandwiching portion 26 that is sandwiched and held upward and downward between the eight footrest portions 9 is provided. Accordingly, when the floor mat 22 is laid on the footrest portion 9, the floor mat 22B is simply inserted between the footrest portion 9 and the mat holding portion 26 of the non-slip member 24. The 22 inclined surface portions 22B can be sandwiched and held between the footrest portion 9 and the mat sandwiching portion 26 of the non-slip member 24 in the upward and downward directions.

この結果、フロアマット22は、その傾斜面部22Bの端部を足乗せ部9とマット挟持部26との間に差し込むという簡単な作業で、足乗せ部9上に確実に保持することができ、位置ずれやめくれ上がりを防止して、作業性や信頼性を向上することができる。   As a result, the floor mat 22 can be securely held on the footrest portion 9 by a simple operation of inserting the end portion of the inclined surface portion 22B between the footrest portion 9 and the mat holding portion 26, Misalignment and turning up can be prevented, and workability and reliability can be improved.

しかも、滑止め部材24にマット挟持部26を設けているから、従来の滑止め部材をマット挟持部が設けられたものに変更するだけで、フロアマット22の端部を簡単に、かつ確実に保持することができる。また、滑止め部材24にマット挟持部26を設けたことにより、滑止め部材24に2つの機能(滑止め機能、マット保持機構)を持たせることができ、足乗せ部9上を狭くすることなく、少ない部品点数でフロアマット22の端部を確実に保持することができる。さらに、マット挟持部26は、フロア部材8との間でフロアマット22の端部を挟むという簡単な方法を用いているから、マット挟持部26は、略L字状に曲げ加工を施すだけで簡単に形成することができる。   Moreover, since the mat holding portion 26 is provided on the non-slip member 24, the end of the floor mat 22 can be easily and reliably changed by simply changing the conventional anti-slip member to one provided with the mat holding portion. Can be held. Further, by providing the mat holding portion 26 in the non-slip member 24, the anti-slip member 24 can have two functions (slip prevention function and mat holding mechanism), and the top of the footrest portion 9 can be narrowed. In addition, the end of the floor mat 22 can be reliably held with a small number of parts. Furthermore, since the mat sandwiching portion 26 uses a simple method of sandwiching the end portion of the floor mat 22 with the floor member 8, the mat sandwiching portion 26 is simply bent into a substantially L shape. It can be easily formed.

また、滑止め部材24は、足乗せ部9の乗降口12側に取付けられオペレータが乗降するときに足を掛ける足掛け板部25と、該足掛け板部25の右側の端部から上方に立上がると共にフロアマット22に向け右側に延びたマット挟持部26と、前記足掛け板部25に上側に突出して設けられた複数個の滑止め突起27とにより構成している。   The anti-slip member 24 is attached to the entrance / exit 12 side of the footrest portion 9 and rises upward from a footrest plate portion 25 on which the operator gets his / her foot when getting on and off, and an end portion on the right side of the footrest plate portion 25. A mat sandwiching portion 26 extending to the right side toward the floor mat 22 and a plurality of anti-slip projections 27 provided on the footrest plate portion 25 so as to protrude upward.
