特開2002−188298号公報JP 2002-188298 A

特許第5263746号公報Japanese Patent No. 5263746

近年、電車などの車両の通路に貼られた長尺シートの張り替えやオフィスビルの一室やマンションの通路の床の張り替えなど、狭い空間での床材剥離作業が増えており、小回りが効き取り扱いし易く、床材を剥離する力が強い床材剥離装置が要求されている。   In recent years, there has been an increase in floor material peeling work in narrow spaces, such as the replacement of long sheets affixed to the passages of vehicles such as trains, and the replacement of floors in rooms in office buildings and apartment passages. There is a demand for a floor material peeling device that is easy to do and has a strong force to peel the floor material.

このような要求に対し、特許第5263746号の装置は小回りが効き取り扱いし易いが、床材を剥離する力は弱いものである。   In response to such a requirement, the device of Japanese Patent No. 5263746 has a small turning effect and is easy to handle, but has a weak force to peel off the flooring.

特許第2608829号の装置は床材を剥離する力が強く、プーリーに掛け渡されたクローラにより前進や後退や旋回ができ、作業者に大きな力を強いることは少ないが、床材離用刃板から手押しハンドルに至るまでの装置の全長が長いので、装置を旋回させる際に広い旋回半径を必要とするものである。   The device of Japanese Patent No. 2608829 has a strong force to peel off the flooring material, and can be moved forward and backward and swiveled by a crawler hung around a pulley. Since the total length of the device from the hand to the handwheel is long, a large turning radius is required when turning the device.

また、特開2002−188298号広報の装置は、床材を剥離する力は十分あるが、装置を旋回させる場合には作業者に苦労を強いるものである。   Further, the device disclosed in Japanese Patent Application Laid-Open No. 2002-188298 has a sufficient force to peel off the flooring material, but when the device is swung, it is difficult for the operator.

図3を用いて特開2002−188298号広報の装置を旋回させる方法を説明する。図3(a)は装置を旋回させる為に、床材剥離用刃板を床から浮かせた状態である。装置の上面には重りが取り付けてあり、装置の自重は約120Kgあるので、作業者は自身の上半身の体重を手押しハンドルの先端にかけて装置を傾ける。この時、装置が後方に傾くので、手押しハンドルを握っている作業者の身体は、装置の後方へ離れる。作業者はこのような姿勢で、床材剥離用刃板が床につかない様に保ちながら、自分自身が車輪を中心に回りながら装置を旋回させる。   A method of turning the device disclosed in Japanese Patent Laid-Open No. 2002-188298 will be described with reference to FIG. FIG. 3A shows a state in which the floor material peeling blade plate is lifted from the floor in order to turn the apparatus. A weight is attached to the upper surface of the apparatus, and the weight of the apparatus is about 120 kg. Therefore, the operator tilts the apparatus by applying the weight of the upper body of the apparatus to the tip of the hand handle. At this time, since the device is tilted rearward, the operator's body holding the handwheel is moved backward from the device. In such a posture, the worker turns the device while turning around the wheel while keeping the floor material peeling blade plate not touching the floor.

図3(b)は、装置を時計回りに180°旋回させた時の軌跡を示している。点Oは旋回の中心であり、左右の車輪の中間点である。円弧A1からA2は床材剥離刃板の移動軌跡であり、点Oから円弧A1からA2までが床材剥離装置の回転半径である。円弧B1からB2は作業者の腰の移動軌跡であり、点Oから円弧B1からB2までが作業者の回転半径である。Wは装置の回転半径と作業者の回転半径の和であり、特開2002−188298号広報の装置ではWは約1400mmであり、装置を旋回させる際には少なくとも1400mmの床幅を必要とする。   FIG. 3B shows a trajectory when the apparatus is turned 180 ° clockwise. Point O is the center of turning and is the midpoint between the left and right wheels. Arcs A1 to A2 are the movement trajectories of the floor material peeling blade plate, and the rotation radius of the floor material peeling device is from point O to arcs A1 to A2. Arcs B1 to B2 are movement trajectories of the operator's waist, and points O to arcs B1 to B2 are the rotation radius of the operator. W is the sum of the turning radius of the device and the turning radius of the operator. In the device disclosed in Japanese Patent Laid-Open No. 2002-188298, W is about 1400 mm, and a floor width of at least 1400 mm is required when turning the device. .

また、従来の装置では、床材剥離用刃板を交換するなど、メンテナンスの際には、装置を横に倒したり、ひっくり返したりする必要があり、この動作は作業者にとっては負担となるものである。   Also, with conventional devices, it is necessary to lay the device sideways or upside down when performing maintenance such as replacing the blade material for peeling the flooring. This operation is a burden on the operator. It is.

以上の様に、従来技術の床材剥離装置は、装置を旋回させる際に、広い床幅を必要とするので、作業現場での装置の取り回しが困難であるという課題と、装置を旋回させる時やメンテナンスの際に作業者に大きな力を強いるという課題を有しており、床材を剥離する力が強くて小回りが効いて取り扱いし易い床材剥離装置はまだ提案されていない。
As described above, the prior art floor material peeling device requires a wide floor width when turning the device, so that it is difficult to handle the device at the work site, and when turning the device. In addition, there is a problem that the operator is forced to exert a great force during maintenance, and a floor material peeling device that has a strong force to peel off the floor material and is easy to handle with a small turn has not yet been proposed.

本発明は上記した課題を解決するもので、床材剥離装置の車台と、前記車台の後部に取り付けられた車輪と、前記車台の前方に取り付けられた床材剥離刃板と、前記車台に取り付けられた手押しハンドルと、前記車台の、前記床材剥離刃板と前記車輪との間に取り付けられた旋回部材を備え、前記床材剥離装置を旋回させる際には、前記旋回部材を、前記床材剥離刃板の先端と前記車輪が床と接地する点を結ぶ直線よりも下方に位置させて床に接地させることにより、前記床材剥離装置の重心より前方で旋回させることを特徴とする。   SUMMARY OF THE INVENTION The present invention solves the above-described problem, and is a chassis of a floor material peeling device, a wheel attached to a rear portion of the chassis, a floor material peeling blade plate attached in front of the chassis, and attached to the chassis. And a swivel member attached between the floor material peeling blade plate and the wheel of the chassis, and when the floor material peeling device is swung, the swivel member is It is made to turn ahead from the center of gravity of the floor material peeling device by positioning it below the straight line connecting the tip of the material peeling blade plate and the point where the wheel comes into contact with the floor and grounding it.

また、前記手押しハンドルの根元を前記車台の、車輪回転軸と旋回部材支持軸の間に取り付けたことを特徴とする。   Further, the base of the hand handle is attached between the wheel rotation shaft and the turning member support shaft of the chassis.

また、前記旋回部材が床材剥離装置の略重心位置から左右へ等距離に2箇所設けられていることを特徴とする。   Further, the swivel member is provided at two positions equidistant from side to side from a substantially center of gravity position of the floor material peeling device.

また、前記旋回部材は、前記床材剥離装置に回動自在に取り付けられたアームに設けられ、アームセットレバーを旋回させることにより、前記アームセットレバーに設けた係止部が前記アームに係止することにより、前記旋回部材を、前記床材剥離刃板の先端と前記車輪が床と接地する点を結ぶ直線よりも下方に位置させて床に接地させることを特徴とする。   The swivel member is provided on an arm that is rotatably attached to the floor material peeling device, and the arm set lever is swung so that a locking portion provided on the arm set lever is locked to the arm. By doing so, the swivel member is placed below the straight line connecting the tip of the floor material peeling blade plate and the point where the wheel contacts the floor, and is grounded to the floor.

また、床材剥離装置の車台と、前記車台の後部に取り付けられた車輪と、前記車台の前方に取り付けられた床材剥離刃板と、前記車台に取り付けられた手押しハンドルと、前記車台の、前記床材剥離刃板と前記車輪との間に取り付けられた旋回部材を備え、前記床材剥離装置を旋回させる際には、前記旋回部材を、前記床材剥離刃板の先端と前記車輪が床と接地する点を結ぶ直線よりも下方に位置させて床に接地させることにより、前記床材剥離装置の重心より後方で旋回させることを特徴とする。   Further, a chassis of a floor material peeling device, a wheel attached to the rear part of the chassis, a floor material peeling blade plate attached to the front of the chassis, a hand handle attached to the chassis, and the chassis, A swivel member attached between the floor material peeling blade plate and the wheel is provided, and when the floor material peeling device is swung, the swivel member is connected to the tip of the floor material peeling blade plate and the wheel. The floor material peeling device is swung behind the center of gravity of the floor material peeling device by being positioned below the straight line connecting the floor and the point to be grounded and being grounded to the floor.

また、床材剥離装置の車台と、前記車台の後部に取り付けられた車輪と、前記車台の前方に取り付けられた床材剥離刃板と、前記車台の、前記床材剥離刃板と前記車輪との間に取り付けられた旋回部材と、前記旋回部材を駆動源を用いて昇降させる手段を備え、前記床材剥離装置を旋回させる際には、前記旋回部材を、前記床材剥離刃板の先端と前記車輪が床と接地する点を結ぶ直線よりも下方に位置させて床に接地させることにより、前記床材剥離装置の重心より前方又は後方で旋回させることを特徴とする。

Further, the chassis of the floor material peeling device, the wheel attached to the rear part of the chassis, the floor material peeling blade plate attached to the front of the chassis, the floor material peeling blade plate and the wheel of the chassis. A swiveling member attached between and a means for moving the swiveling member up and down using a drive source, and when swiveling the floor material peeling device, the swiveling member is positioned at the tip of the floor material peeling blade plate. And the wheel is positioned below a straight line connecting the point where the wheel contacts the floor and is grounded to the floor, thereby turning forward or backward from the center of gravity of the floor material peeling device.

本発明の床材剥離装置では、旋回部材を床材剥離刃板の先端と車輪が床と接地する点を結ぶ直線よりも下方に位置させて床に接地させ、床材剥離装置の重心より前方で旋回させるので、床材剥離装置を旋回させる際の床材剥離装置の回転半径と作業車の回転半径の和が小さいので狭い床幅で旋回できる。   In the floor material peeling device of the present invention, the swivel member is positioned below the straight line connecting the tip of the floor material peeling blade plate and the point where the wheel contacts the floor, and is grounded to the floor, and forward of the center of gravity of the floor material peeling device. Since the sum of the rotation radius of the floor material peeling device and the rotation radius of the work vehicle when turning the floor material peeling device is small, the vehicle can turn with a narrow floor width.

また、手押しハンドルのハンドルグリップは床材剥離装置の後端より前方に位置しているので、作業者は床材剥離装置から離れることなく旋回できるので、作業者が旋回時に必要とする幅は小さい。   In addition, since the handle grip of the push handle is located in front of the rear end of the floor material peeling device, the operator can turn without leaving the floor material peeling device, so the width required by the operator when turning is small. .

また、手押しハンドルの根元は、床材剥離装置の重心に近いところに取り付けられているので、作業者は小さい力で床材剥離装置の安定を保持することができる。    Moreover, since the base of the handwheel handle is attached at a position close to the center of gravity of the floor material peeling device, the operator can maintain the stability of the floor material peeling device with a small force.

本発明の床材剥離装置では、床材剥離装置の後部端面よりも後方へ突き出しているセットレバー取手を押し下げることにより、アームセットレバーが旋回して、旋回部材を、床材剥離刃板の先端と車輪が床と接地する点を結ぶ直線よりも下方に位置させて床に接地させることができるので、作業者は床材剥離装置の手押しハンドルに設けられたハンドルグリップを握っている手を放すことなく旋回準備ができる。 In the floor material peeling device of the present invention, the arm set lever pivots by pushing down the set lever handle protruding rearward from the rear end face of the floor material peeling device, and the swiveling member is moved to the tip of the floor material peeling blade plate. And the wheel can be placed below the straight line connecting the point where the wheel contacts the floor, so that the worker can release the hand holding the handle grip provided on the push handle of the floor material peeling device. You can prepare for turning without any trouble.

また、車輪と旋回部材が床に接地して床材剥離用刃板が床から離れた状態で床材剥離装置を保持できるのでメンテナンス時に作業者は床材剥離装置を倒す必要はない。   Further, since the floor material peeling device can be held in a state where the wheel and the turning member are grounded to the floor and the floor material peeling blade plate is separated from the floor, the operator does not need to defeat the floor material peeling device during maintenance.

以上の様に、本発明の床材剥離装置は、作業現場で装置を旋回させる時やメンテナンスの際に作業者に大きな力を強いることなく、床材を剥離する力が強くて小回りが効いて取り扱いし易い床材剥離装置である。

車台(2)の前方に、床材剥離用刃板(11)を取り付けた刃物ブラケット(10)が設けられ、刃物ブラケット(10)はコネクティングロッド(9)を介して偏芯回転軸(8)に取り付けられており、偏芯回転軸(8)にはチェーン(図示せず)と歯車(図示せず)によりモーター(7)の回転が伝達され、床材剥離用刃板(11)は床材剥離装置(1)の前後方向に摺動運動する。   A blade bracket (10) to which a floor material peeling blade (11) is attached is provided in front of the chassis (2), and the blade bracket (10) is connected to the eccentric rotation shaft (8) via the connecting rod (9). The rotation of the motor (7) is transmitted to the eccentric rotation shaft (8) by a chain (not shown) and a gear (not shown), and the floor material peeling blade (11) is attached to the floor. The material peeling device (1) slides in the front-rear direction.

また、車台(2)の上部には、床材剥離装置(1)の重量を重くして、床材剥離用刃板(11)を床に押さえつける力を強くする為の重り(6)がボルト(図示せず)により、車台(2)に脱着可能に取り付けられている。本発明の床材剥離装置(1)は重り(6)も含めて約120Kgである。   Further, a weight (6) for increasing the weight of the floor material peeling device (1) and pressing the floor material peeling blade (11) against the floor is bolted to the upper part of the chassis (2). (Not shown) is detachably attached to the chassis (2). The floor material peeling apparatus (1) of the present invention is about 120 kg including the weight (6).

続いて、旋回部材(13)について説明する。旋回部材(13)は床材剥離用刃板(11)と車輪(12)の間に位置し、床材剥離装置(1)の前後方向の重心付近の底部に、左右一対のアーム(14)に軸支された旋回部材支持軸(27)に回転可能に取り付けられてた旋回軸(13b)と、旋回軸(13b)に回転可能に設けた接地板(13a)と、旋回部材支持軸(27)に対して旋回軸(13b)の位置がずれないように係止するための2つの係止部材(13c)から構成されている。また、アーム(14)は、アーム支点(15)により車台(2)に回動可能に取り付けられているので、旋回部材(13)はアーム支点(15)を支点に上下に移動可能に構成されている。   Then, a turning member (13) is demonstrated. The swivel member (13) is positioned between the floor material peeling blade (11) and the wheel (12), and a pair of left and right arms (14) at the bottom of the floor material peeling device (1) near the center of gravity in the front-rear direction. A swivel shaft (13b) rotatably attached to a swivel member support shaft (27) pivotally supported by the shaft, a grounding plate (13a) rotatably provided on the swivel shaft (13b), and a swivel member support shaft ( 27) It is comprised from the two latching members (13c) for latching so that the position of a rotating shaft (13b) may not shift | deviate with respect to 27). Moreover, since the arm (14) is rotatably attached to the chassis (2) by the arm fulcrum (15), the turning member (13) is configured to be movable up and down with the arm fulcrum (15) as a fulcrum. ing.

また、本発明の床材剥離装置(1)では、セットレバー(18)は床材剥離装置(1)の後部端面よりも後方へ突き出しているので、作業者は床材剥離装置(1)の手押しハンドル(28)に設けられたハンドルグリップ(3)から手を放すことなく、床材剥離装置(1)から離れることなく、セットレバー取手(25)を押し下げることができる。   Moreover, in the floor material peeling apparatus (1) of this invention, since the set lever (18) protrudes back rather than the rear part end surface of the floor material peeling apparatus (1), an operator is a floor material peeling apparatus (1). The set lever handle (25) can be pushed down without releasing the hand from the handle grip (3) provided on the push handle (28) and without leaving the floor material peeling device (1).

また、旋回部材(13)を接地させて床材剥離装置(1)を旋回し易い状態にするため、床材剥離装置(1)の左右一対のセットレバー(18)が、セットレバー支点(21)により、車台(2)に回動可能に取り付けられており、左右一対のセットレバー(18)はセットレバー取手(25)により連結されている。また、セットレバー(18)には、アーム(14)に設けられた係止受部(16)にはまり込むことでアーム(14)の回動を係止する係止部(19)が設けられている。また、セットレバー(18)にはセットレバー重り(20)が取り付けられている。   In addition, in order to make the swivel member (13) ground and make the floor material peeling device (1) easy to swivel, the pair of left and right set levers (18) of the floor material peeling device (1) are connected to the set lever fulcrum (21 ) Is rotatably attached to the chassis (2), and the pair of left and right set levers (18) are connected by a set lever handle (25).

Since it hits the stopper screw (24) provided on the chassis (2), the set lever (18) does not rotate further counterclockwise.

続いて、旋回部材(13)の上下移動について説明する。
図1(a)は、床材剥離装置(1)は凹凸の無い平らな床の上に置かれ、旋回部材(13)は、自重により床に接地している状態である。
Next, the vertical movement of the turning member (13) will be described.
FIG. 1A shows a state in which the floor material peeling device (1) is placed on a flat floor without unevenness, and the turning member (13) is in contact with the floor by its own weight.

また、床が上に膨らんでいる場合は、旋回部材(13)は床の膨らみに沿って上へ移動し、アーム(14)の下面がセットレバー(18)に設けられている係止部(19)に当接してアーム(14)の回動が規制される位置まで移動する。   When the floor is swollen upward, the swiveling member (13) moves upward along the swollen floor, and the lower surface of the arm (14) is a locking portion (provided with the set lever (18)). 19) and moves to a position where the rotation of the arm (14) is restricted.

続いて、旋回部材(13)を床に設置させ方を説明する。図1(a)の状態で、作業者により、セットレバー取手(25)が押し下げられると、セットレバー(18)は、(図1(a)では)時計回りに回動しセットレバー(18)に設けられた係止部(19)がアーム(14)の下面に設けられている係止部受部(16)の左に当接する。この位置から更にセットレバー取手(25)が押し下げられると、アーム(14)が反時計方向へ旋回するので旋回部材(13)が接地した状態で床材剥離装置(1)の前方が持ち上がり床材剥離用刃板(11)の先端が床から離れる。
そして、係止部(19)が係止部受部(16)にはまり込むと、アーム(14)の回動は止められ旋回部材(13)が接地された状態で固定される。床材剥離装置(1)では、旋回部材(13)は、床材剥離装置(1)の前後方向の重心よりも前方で床に接地する様にしているので、床材剥離用刃板(11)が床から離れ、車輪(12)と旋回部材(13)により床に接地された状態となる。本発明の床材剥離装置(1)では、床材剥離用刃板(11)は約50mm床から離れる。
Then, the method of installing a turning member (13) on a floor is demonstrated. When the set lever handle (25) is pushed down by the operator in the state of FIG. 1 (a), the set lever (18) rotates clockwise (in FIG. 1 (a)) and the set lever (18). The locking part (19) provided on the left side of the locking part receiving part (16) provided on the lower surface of the arm (14) comes into contact with the left side. When the set lever handle (25) is further pushed down from this position, the arm (14) turns counterclockwise, so that the front of the floor material peeling device (1) is lifted with the turning member (13) grounded. The tip of the peeling blade plate (11) is separated from the floor.
Then, when the locking part (19) fits into the locking part receiving part (16), the rotation of the arm (14) is stopped and the turning member (13) is fixed in a grounded state. In the floor material peeling device (1), the swivel member (13) is in contact with the floor in front of the center of gravity in the front-rear direction of the floor material peeling device (1). ) Leaves the floor and is grounded to the floor by the wheel (12) and the turning member (13). In the floor material peeling apparatus (1) of the present invention, the floor material peeling blade (11) is separated from the floor by about 50 mm.

続いて、本発明の床材剥離装置(1)を用いて床材剥離作業を行っている状態を説明する。運転スイッチ(5)をONしてモーター(7)を回転させると、床材剥離用刃板(11)は前後に摺動し、車輪(12)は前進方向に駆動するが、床材が剥がれにくい所もあるので、作業者は手押しハンドル(28)を前方へ押して力を加えながら、蛇行しないように修正しながら床材を剥がしていく。   Then, the state which is performing the floor material peeling operation | work using the floor material peeling apparatus (1) of this invention is demonstrated. When the operation switch (5) is turned on and the motor (7) is rotated, the floor material peeling blade (11) slides back and forth and the wheel (12) is driven in the forward direction, but the floor material is peeled off. Since there are some difficult places, the operator pushes the push handle (28) forward to apply force, and peels off the floor material while correcting so as not to meander.

また、図1(a)の状態では旋回部材(13)は固定されていないので、アーム(14)の係止受部(16)を設けている側の重量を重り(図示せず)を設けるなど重くしておき、旋回部材(13)が接地しないようにしている。   Further, in the state of FIG. 1 (a), since the turning member (13) is not fixed, a weight (not shown) is provided on the side of the arm (14) where the locking receiving portion (16) is provided. The swivel member (13) is prevented from being grounded.

また、前進を一時停止させたり、進め方向を変えたい場合は、作業者はクラッチレバー(4)を握って車輪(12)の回転を止める。   Further, when the advance is temporarily stopped or the advance direction is desired to be changed, the operator holds the clutch lever (4) and stops the rotation of the wheel (12).

続いて、本発明の床材剥離装置(1)を旋回させる方法を説明する。図2(a)は、旋回部材(13)が床に接地されて固定され、車輪(12)と旋回部材(13)が床に接地して床材剥離用刃板(11)だけが床から離れた状態から、作業者が手押しハンドル(28)を前方へ押して、車輪(12)も床から浮かせて保持している状態である。   Next, a method for turning the floor material peeling device (1) of the present invention will be described. In FIG. 2A, the swivel member (13) is grounded and fixed to the floor, the wheel (12) and the swivel member (13) are grounded to the floor, and only the floor material peeling blade (11) is removed from the floor. From the separated state, the operator pushes the hand handle (28) forward, and the wheel (12) is also lifted from the floor and held.

本発明の床材剥離装置(1)では、手押しハンドル(28)の根元を、車台(2)の、旋回部材(13)に近いところに取り付けているので、作業者は小さい力で床材剥離装置(1)を図2(a)の状態に、旋回部材(13)だけ接地した状態に保持できる。   In the floor material peeling apparatus (1) according to the present invention, the base of the push handle (28) is attached to the chassis (2) near the turning member (13). The device (1) can be held in the state shown in FIG.

図2(a)の状態で、作業者は床材剥離装置(1)を、旋回部材(13)の旋回中心で旋回させる。すなわち旋回部材(13)の接地板(13a)を床に接地させて旋回軸(13b)を接地板(13a)に対して旋回中心で旋回させるのである。   In the state of FIG. 2A, the operator turns the floor material peeling device (1) around the turning center of the turning member (13). That is, the grounding plate (13a) of the turning member (13) is grounded to the floor, and the turning shaft (13b) is turned around the turning center with respect to the grounding plate (13a).

本発明の床材剥離装置(1)では、ハンドルグリップ(3)が、車台(2)の後端よりも前方の位置になるように手押しハンドル(28)を取り付けているので、作業者は床材剥離装置(1)から離れることなくの旋回の中心に近いところに立つことができる。   In the floor material peeling apparatus (1) according to the present invention, the hand grip (28) is attached so that the handle grip (3) is in front of the rear end of the chassis (2). It is possible to stand near the center of turning without leaving the material peeling device (1).

図2(b)は、床材剥離装置(1)を時計回りに180°旋回させた時の軌跡を示している。点Oは旋回の中心であり、旋回部材(13)の旋回中心点である。円弧A1からA2は床材剥離刃板(11)の移動軌跡であり、点Oから円弧A1からA2までが床材剥離装置(1)の回転半径であり、円弧B1からB2は作業者の腰の移動軌跡であり、点Oから円弧B1からB2までが作業者の回転半径である。
Wは床材剥離装置(1)の回転半径と作業者の回転半径の和であり、発明の床材剥離装置(1)では、Wは約1000mmであり、1000mmの床幅がれば床材剥離装置(1)を旋回させることができる。
FIG. 2B shows a trajectory when the floor material peeling device (1) is turned 180 ° clockwise. Point O is the center of turning, and is the turning center point of the turning member (13). Arcs A1 to A2 are the movement trajectory of the floor material peeling blade plate (11), the point O to the arc A1 to A2 are the turning radius of the floor material peeling device (1), and the arcs B1 to B2 are the waist of the operator. The moving radius of the operator is from the point O to the arcs B1 to B2.
W is the sum of the rotation radius of the floor material peeling device (1) and the rotation radius of the operator. In the floor material peeling device (1) of the invention, W is about 1000 mm, and if the floor width is 1000 mm, the floor material The peeling device (1) can be turned.

続いて、旋回部材(13)の固定、すなわちアーム(14)とセットレバー(18)を解除する方法について図2(a)を用いて説明する。作業者は手押しハンドル(28)を自分の方向へ引いて図2(a)の状態から車輪(12)を床に接地させ、更に手押しハンドル(28)を自分の方向へ引くとアーム(14)は反時計回りに回動し、係止部(19)が係止部受部(16)から外れる。セットレバー(18)は、セットレバー重り(20)により反時計回りに回動し、プランジャー(22)がプランジャー受け孔(22)にはまり込む直前で停止する。作業者はセットレバー取手(25)を持ち上げて、プランジャー(22)をプランジャー受け孔(22)にはまり込ませるとセットレバー(18)は固定される。アーム(14)の係止受部(16)を設けている側の重量を重り(図示せず)を設けるなど重くしているので、アーム(14)が図2(a)において時計周りに回動して旋回部材(13)が浮き上がり解除が完了する。   Next, a method of fixing the turning member (13), that is, a method of releasing the arm (14) and the set lever (18) will be described with reference to FIG. The operator pulls the hand handle (28) in his / her direction to ground the wheel (12) from the state of FIG. 2 (a) to the floor, and further pulls the hand handle (28) in his / her direction to the arm (14). Rotates counterclockwise, and the locking portion (19) is disengaged from the locking portion receiving portion (16). The set lever (18) is rotated counterclockwise by the set lever weight (20), and stops immediately before the plunger (22) gets into the plunger receiving hole (22). When the operator lifts the set lever handle (25) and inserts the plunger (22) into the plunger receiving hole (22), the set lever (18) is fixed. Since the weight of the arm (14) on which the latch receiving portion (16) is provided is increased in weight (not shown), the arm (14) rotates clockwise in FIG. 2 (a). The swiveling member (13) is lifted to complete the release.

図3は、旋回部材(33)の別の実施形態を説明した図である。床材剥離装置(1)の構成はほぼ同じであるので、同じ作用のものは図1の符号と同様の符号で表示している。   Drawing 3 is a figure explaining another embodiment of turning member (33). Since the structure of the floor material peeling apparatus (1) is substantially the same, the thing of the same effect | action is displayed with the code | symbol similar to the code | symbol of FIG.

旋回部材支持軸(27)はアーム(14)に固定されて回転しないようにされており、旋回部材支持軸(27)に旋回部材(33)が図3(b)に示すように旋回部材支持軸(27)の中央付近に固定されている。この旋回部材(33)は、床に接地する接地面(33a)が球面とされており、床面に点で接地するようにしており、旋回部材(33)だけで接地させた状態とした場合に旋回しやすい構成としているのである。旋回部材(33)だけで接地させる手順や、解除の手順は図1、図2を用いた実施形態で説明した内容と同様の手順である。本実施形態においても、床材剥離装置(1)の前後方向の重心よりも前方で床に接地する様にしているので、床材剥離用刃板(11)が床から離れ、車輪(12)と旋回部材(33)により床に接地された状態となる。   The turning member support shaft (27) is fixed to the arm (14) so as not to rotate. The turning member support shaft (27) is supported by the turning member (33) as shown in FIG. 3B. It is fixed near the center of the shaft (27). The swivel member (33) has a ground contact surface (33a) that is grounded to the floor, and is grounded at a point to the floor surface, and is in a state of being grounded only by the swivel member (33). The structure is easy to turn. The procedure for grounding only by the turning member (33) and the releasing procedure are the same as those described in the embodiment using FIGS. Also in this embodiment, since the floor material peeling device (1) is in contact with the floor in front of the center of gravity in the front-rear direction, the floor material peeling blade (11) is separated from the floor and the wheel (12). And it will be in the state grounded to the floor by the turning member (33).

図4は、図3の旋回部材(33)と同様の部材を旋回部材支持軸(27)に床材剥離装置(1)の本体左右端部付近にそれぞれ旋回部材(43a)と旋回部材(43b)として設けたものである。旋回部材(43a)には接地面(43c)が、旋回部材(43b)には接地面(43d)がそれぞれ旋回部材(33)と同様に球面状に設けられている。   FIG. 4 shows a turning member (43a) and a turning member (43b) in the vicinity of the left and right ends of the main body of the floor material peeling device (1) on the turning member support shaft (27). ). The swivel member (43a) is provided with a ground contact surface (43c), and the swivel member (43b) is provided with a ground contact surface (43d) in the same spherical shape as the swivel member (33).

右旋回する場合は右の旋回部材(43b)を中心に回転させてもよく、あるいは、左旋回する場合は左の旋回部材(43a)を旋回の中心として床材剥離装置(1)を回転させるのである。   When turning right, the right turning member (43b) may be rotated around the center, or when turning left, the floor material peeling device (1) is rotated around the left turning member (43a) as the center of turning. To make it happen.

本実施形態においても、床材剥離装置(1)の前後方向の重心よりも前方で床に接地する様にしているので、床材剥離用刃板(11)が床から離れ、車輪(12)と旋回部材(43a)、旋回部材(43b)により床に接地された状態となる。   Also in this embodiment, since the floor material peeling device (1) is in contact with the floor in front of the center of gravity in the front-rear direction, the floor material peeling blade (11) is separated from the floor and the wheel (12). And the swivel member (43a) and the swivel member (43b) are grounded to the floor.
