Description

この発明は、送電線鉄塔などの構造物を昇降するために足場として取り付けられる昇降用ステップに関する。   The present invention relates to an ascending / descending step attached as a scaffold for elevating a structure such as a transmission line tower.

例えば、送電線鉄塔は、アングル材（等辺山型鋼）で主柱材（メインポスト）が構成され、主柱材には足場としてのステップボルトが取り付けられているが、保安上、第三者が鉄塔に昇らないように、地上から所定の高さまではステップボルトが外されている。このため、作業や点検などのために鉄塔を昇降する場合には、ステップボルトを所持して主柱材に取り付けたり、取り外したりしなければならない。しかしながら、通常のステップボルトはボルトとナットから構成されているため、手間と時間を要するばかりでなく、主柱材にボルトを挿入するための孔が形成されていなければならず、任意の位置に取り付けることができない。   For example, the transmission line tower is composed of angle materials (equal mountain type steel) and main pillar materials (main posts), and the main pillar materials are equipped with step bolts as scaffolding. Step bolts are removed from the ground at a predetermined height so as not to climb the tower. For this reason, when raising or lowering a steel tower for work or inspection, it is necessary to carry a step bolt and attach it to or remove it from the main pillar material. However, since ordinary step bolts are composed of bolts and nuts, not only labor and time are required, but holes for inserting the bolts into the main pillar material must be formed at any position. It cannot be installed.

このため、臨時的に任意の位置に取り付けることができ、かつ、堅牢で着脱可能な足場が知られている（例えば、特許文献１参照。）。この足場は、相対向する内側面がプレート（構造物の部材）にそれぞれ当接される平面で、かつ内側面の反対面であるそれぞれの外側面が一方向に向けて肉厚を漸増させる傾斜面となっている一対の楔部材と、コ字状の相対向する面に、楔部材の傾斜面に当接し得る傾斜面が形成され、一方向に向けて楔部材に嵌入される固定部材と、固定部材の少なくとも一つの外周面から一方向に交差する方向に突出させて固定部材に固着されたステップボルトと、を有するものである。   For this reason, a scaffold that can be temporarily attached to an arbitrary position and is detachable and detachable is known (see, for example, Patent Document 1). In this scaffold, the inner surfaces facing each other are flat surfaces that are in contact with the plates (members of the structure), and the outer surfaces opposite to the inner surfaces are inclined so that the thickness gradually increases in one direction. A pair of wedge members that are surfaces, and a fixed member that is formed in the U-shaped opposing surfaces so that an inclined surface that can contact the inclined surface of the wedge member is formed and is fitted into the wedge member in one direction. And a step bolt fixed to the fixing member so as to protrude in a direction crossing in one direction from at least one outer peripheral surface of the fixing member.

特開２０１３−１７０３９９号公報JP 2013-170399 A

ところで、特許文献１の足場を送電線鉄塔などに取り付けるには、楔部材の平面間にアングル材（プレート）の両面を相対向させて、ハンマーで固定部材の上端面を下方に叩き込む。これにより、固定部材の傾斜面が楔部材の傾斜面に沿って下降して、楔作用により楔部材がアングル材に固定される。また、足場を送電線鉄塔などから取り外すには、ハンマーで固定部材の下端面を上方に叩き上げる。これにより、固定部材の傾斜面が楔部材の傾斜面に沿って上昇して、楔部材によるアングル材の挟持力が緩み、アングル材から取り外れるものである。   By the way, in order to attach the scaffold of Patent Document 1 to a transmission line tower or the like, both surfaces of an angle member (plate) are opposed to each other between the planes of the wedge member, and the upper end surface of the fixing member is struck downward with a hammer. Thereby, the inclined surface of the fixing member descends along the inclined surface of the wedge member, and the wedge member is fixed to the angle member by the wedge action. In addition, to remove the scaffold from the transmission line tower, the lower end surface of the fixing member is struck upward with a hammer. Thereby, the inclined surface of the fixing member rises along the inclined surface of the wedge member, and the clamping force of the angle member by the wedge member is loosened and removed from the angle member.

このように、足場を取り付けたり取り外したりするのに、両手を使わなければならないばかりでなく、ハンマー（工具）を所持して叩く必要があり、手間と時間を要する。殊に、高い位置で足場を着脱する場合には、不安定で作業者に負担となる。しかも、鉄塔などからハンマーを落下させるおそれがある。   Thus, in order to attach and detach the scaffold, not only must both hands be used, but it is necessary to carry and hit a hammer (tool), which takes time and effort. In particular, when the scaffold is attached and detached at a high position, it is unstable and burdens the operator. Moreover, there is a risk of dropping the hammer from a steel tower.

そこでこの発明は、工具を使わずに片手で着脱することが可能な昇降用ステップを提供することを目的とする。   Accordingly, an object of the present invention is to provide an elevating step that can be attached and detached with one hand without using a tool.

ここで、足場体４の強度・剛性、径および長さは、人の足を安定して載せることができ、かつ、持ち運びしやすいように設定されている。   Here, the strength / rigidity, diameter, and length of the scaffold body 4 are set so that a person's foot can be stably placed and easy to carry.

次に、このような構成の昇降用ステップ１の作用などについて説明する。   Next, the operation of the ascending / descending step 1 having such a configuration will be described.

送電線鉄塔を昇降するに際して、昇降用ステップ１を主柱材１０１に取り付けるには、まず、主柱材１０１の一片部１０２の所望箇所を挟持体２の挟持部２１、２２間に挿入する。これにより、弾性体３と第２の挟持部２２とで一片部１０２が仮挟持されて、挟持体２つまり昇降用ステップ１が主柱材１０１に仮保持される。次に、足場体４を締め込むと、足場体４と第２の挟持部２２とで一片部１０２が強固に挟持されて、足場体４つまり昇降用ステップ１が主柱材１０１に固定される。この際、一片部１０２の長手方向に対して足場体４が略垂直に延びるように取り付けられる。   In order to attach the lifting / lowering step 1 to the main column member 101 when moving up and down the transmission line tower, first, a desired portion of one piece 102 of the main column member 101 is inserted between the holding portions 21 and 22 of the holding member 2. Thus, the one piece portion 102 is temporarily clamped by the elastic body 3 and the second clamping portion 22, and the clamping body 2, that is, the lifting step 1 is temporarily held by the main column member 101. Next, when the scaffold body 4 is tightened, the one piece portion 102 is firmly sandwiched between the scaffold body 4 and the second sandwiching portion 22, and the scaffold body 4, that is, the lifting step 1 is fixed to the main column member 101. . At this time, the scaffold body 4 is attached so as to extend substantially perpendicular to the longitudinal direction of the one piece portion 102.

そして、この足場体４に足を載せたり手を掛けたりして送電線鉄塔を昇降する。この際、ハンドル４３をスライドさせて邪魔にならないようにハンドル４３を位置させたり、あるいは、抜け止め４４を外してハンドル４３を足場体４から取り外したりする。その後、昇降用ステップ１を取り外すには、足場体４を緩めて挟持体２を一片部１０２から外せばよい。   And a foot is put on this scaffolding body 4, and a hand is put, and a power transmission line tower is raised / lowered. At this time, the handle 43 is slid so as not to get in the way, or the handle 43 is removed from the scaffold body 4 by removing the stopper 44. Thereafter, the lifting step 1 can be removed by loosening the scaffold body 4 and removing the sandwiching body 2 from the one-piece portion 102.

以上のように、この昇降用ステップ１によれば、挟持部２１、２２間に一片部１０２を挿入して足場体４を締め込むだけで、容易かつ迅速に主柱材１０１に取り付けることができ、また、足場体４を緩めて挟持体２を一片部１０２から外すだけで、容易かつ迅速に主柱材１０１から取り外すことができる。つまり、容易かつ迅速に足場を送電線鉄塔に着脱することが可能となる。しかも、挟持部２１、２２間に一片部１０２を挿入することで、昇降用ステップ１が主柱材１０１に仮保持されるため、片手で着脱することが可能となる。つまり、片手で挟持部２１、２２間に一片部１０２を挿入して片手で足場体４を締め込んだり、片手で足場体４を緩めて片手で挟持体２を一片部１０２から外したりすることができる。   As described above, according to the step 1 for raising and lowering, it is possible to easily and quickly attach the main pillar 101 by inserting the one piece 102 between the holding portions 21 and 22 and fastening the scaffold body 4. Moreover, it is possible to easily and quickly remove the scaffold body 4 from the main column member 101 simply by loosening the scaffold body 4 and removing the sandwiching body 2 from the one piece portion 102. That is, the scaffold can be easily attached to and detached from the transmission line tower. In addition, by inserting the one piece 102 between the sandwiching portions 21 and 22, the elevating step 1 is temporarily held by the main pillar 101, so that it can be attached and detached with one hand. That is, insert the one piece 102 between the holding portions 21 and 22 with one hand and tighten the scaffold body 4 with one hand, or loosen the scaffold body 4 with one hand and remove the holding body 2 from the one piece 102 with one hand. Can do.

また、足場体４を締め込んだり緩めたりするだけでよいので、工具（ハンマーやレンチなど）を使わずに着脱することが可能となる。しかも、ハンドル４３を持って足場体４を回すことで、所定の力・トルクで足場体４を適正に締め込むことができる。さらに、足場体４が回転体を兼ねているため、構成が簡易となり、取り扱いも容易となる。また、仮保持手段が弾性体３で構成されているだけであるため、構成がより簡易となる。   Further, since the scaffold body 4 only needs to be tightened or loosened, it can be attached and detached without using a tool (such as a hammer or a wrench). In addition, the scaffold body 4 can be properly tightened with a predetermined force and torque by holding the handle 43 and rotating the scaffold body 4. Furthermore, since the scaffold body 4 also serves as a rotating body, the configuration is simplified and the handling is facilitated. Further, since the temporary holding means is only composed of the elastic body 3, the configuration becomes simpler.

一方、送電線鉄塔の主柱材１０１にボルトを挿入するための孔などを加工、形成する必要がなく、任意の位置に取り付けることができる。このようにして、容易かつ安定して安全に、しかも、任意の位置に足場を送電線鉄塔に着脱することが可能となる。また、一片部１０２を挟む挟持体２（弾性体３を含む）と足を載せる足場体４とを備えるだけであるため、小型化、軽量化が可能で、持ち運びや取り扱いが容易となる。   On the other hand, there is no need to process and form holes for inserting bolts into the main pillar 101 of the transmission line tower, and it can be attached at an arbitrary position. In this way, the scaffold can be attached to and detached from the transmission line tower at an arbitrary position easily, stably and safely. In addition, since only the sandwich body 2 (including the elastic body 3) sandwiching the one piece portion 102 and the scaffold body 4 on which the foot is placed are provided, the size and weight can be reduced, and the carrying and handling are easy.

（実施の形態２）
図２は、この実施の形態に係る昇降用ステップ１を示す平面図（一部断面図）である。この実施の形態では、仮保持手段として弾性体３に代って磁石３１を備える点で実施の形態１と構成が異なり、実施の形態１と同等の構成については、同一符号を付することでその説明を省略する。 (Embodiment 2)
FIG. 2 is a plan view (partially sectional view) showing step 1 for raising and lowering according to this embodiment. In this embodiment, the configuration is different from that of the first embodiment in that a magnet 31 is provided instead of the elastic body 3 as a temporary holding means, and a configuration equivalent to that of the first embodiment is denoted by the same reference numeral. The description is omitted.

磁石３１は、第２の挟持部（一方の挟持部）２２の内面２２ａ側に設けられ、挟持部２１、２２間に一片部１０２を挿入することで、磁石３１の磁力によって第２の挟持部２２が一片部１０２に付着し、昇降用ステップ１が主柱材１０１に仮保持される。ここで、磁石３１の磁力と大きさは、昇降用ステップ１を安定して仮保持できるように設定されている。   The magnet 31 is provided on the inner surface 22 a side of the second clamping part (one clamping part) 22, and the one clamping part 102 is inserted between the clamping parts 21, 22, whereby the second clamping part is obtained by the magnetic force of the magnet 31. 22 is attached to the one piece portion 102, and the lifting step 1 is temporarily held by the main pillar 101. Here, the magnetic force and magnitude of the magnet 31 are set so that the lifting step 1 can be temporarily held stably.

また、足場体４は、第１の挟持部（他方の挟持部）２１に形成されたネジ孔２１ａを貫通して螺合されている。そして、足場体４を回転体として締め込むと、足場体４と第２の挟持部２２とで一片部１０２が強固に挟持されて、足場体４つまり昇降用ステップ１が主柱材１０１に取り付けられる。   In addition, the scaffold body 4 is screwed through a screw hole 21 a formed in the first clamping part (the other clamping part) 21. When the scaffold body 4 is tightened as a rotating body, the one piece 102 is firmly sandwiched between the scaffold body 4 and the second sandwiching section 22, and the scaffold body 4, that is, the lifting step 1 is attached to the main column member 101. It is done.

この実施の形態によれば、実施の形態１と同様に、昇降用ステップ１を工具を使わずに、かつ片手で着脱することが可能で、容易かつ安定して安全に、しかも、任意の位置に足場を送電線鉄塔に着脱することが可能となる。また、仮保持手段が磁石３１で構成されているだけであるため、構成がより簡易となるとともに、挟持体２つまり昇降用ステップ１を主柱材１０１により確実に仮保持することが可能となる。   According to this embodiment, as in the first embodiment, the lifting step 1 can be attached and detached with one hand without using a tool, easily, stably and safely, and at any position. In addition, the scaffold can be attached to and detached from the transmission line tower. In addition, since the temporary holding means is only composed of the magnet 31, the configuration becomes simpler, and the holding body 2, that is, the lifting step 1 can be securely temporarily held by the main column member 101. .

（実施の形態３）
図３〜図６は、この実施の形態を示し、実施の形態１と同等の構成については、同一符号を付することでその説明を省略する。
この実施の形態では、仮保持手段が、挟持部２１、２２間に配設されたバネ材２４で構成され、挟持部２１、２２間に一片部１０２を挿入することで、バネ材２４の弾性力によって両挟持部２１、２２で一片部１０２を仮挟持する。すなわち、平板状の第１の挟持部２１と第２の挟持部２２とが一端部において、棒状の連結部２３を介して接続され、第２の挟持部２２は連結部２３に沿ってスライド自在となっている。また、連結部２３に巻き付くように圧縮コイルバネであるバネ材２４が、挟持部２１、２２間に配設され、これにより、洗濯バサミのように、挟持部２１、２２の他端部側が接近・当接するようになっている。 (Embodiment 3)
3 to 6 show this embodiment, and the same components as those in the first embodiment are denoted by the same reference numerals and the description thereof is omitted.
In this embodiment, the temporary holding means is constituted by the spring material 24 disposed between the sandwiching portions 21 and 22, and the elastic member of the spring material 24 is inserted by inserting the one piece portion 102 between the sandwiching portions 21 and 22. One piece part 102 is temporarily clamped by both clamping parts 21 and 22 by force. That is, the flat plate-like first clamping part 21 and the second clamping part 22 are connected to each other at one end via a bar-like connecting part 23, and the second clamping part 22 is slidable along the connecting part 23. It has become. Further, a spring material 24, which is a compression coil spring, is disposed between the sandwiching portions 21 and 22 so as to wrap around the connecting portion 23, so that the other end side of the sandwiching portions 21 and 22 approaches like a clothespin.・ It comes in contact.

さらに、挟持部２１、２２の他端部側の内面には、ゴムなどで構成されて弾性を有するグリップ２５が配設されている。そして、挟持部２１、２２間の他端部側に一片部１０２を挿入すると、図３に示すように、バネ材２４の弾性力によって両挟持部２１、２２で一片部１０２が仮挟持される。また、挟持部２１、２２の一端部側を接近させてバネ材２４を縮めると、図４に示すように、挟持部２１、２２の他端部側が開いて一片部１０２の仮挟持が解除される。   Furthermore, grips 25 made of rubber or the like and having elasticity are disposed on the inner surfaces of the holding parts 21 and 22 on the other end side. When the one piece portion 102 is inserted into the other end portion between the holding portions 21 and 22, the one piece portion 102 is temporarily held between the holding portions 21 and 22 by the elastic force of the spring material 24 as shown in FIG. . Moreover, when the one end part side of the clamping parts 21 and 22 is approached and the spring material 24 is contracted, as shown in FIG. 4, the other end part side of the clamping parts 21 and 22 is opened and the temporary clamping of the one piece part 102 is released. The

足場体５は、両挟持部２１、２２の中央部を貫通し、足を載せる側とは反対側の端部にネジ部５１が形成されている。すなわち、鉄鋼製の丸棒状で、一端部にネジ部５１が形成され、このネジ部５１が両挟持部２１、２２を貫通して第２の挟持部２２の外面（一片部１０２側の反対面）から突出している。また、ネジ部５１が貫通する第２の挟持部２２の挿入孔２２ａは、外面側に大径の略円錐台状で、ネジ部５１との間に隙間を有し、図３、図４に示すように、第２の挟持部２２が可動（揺動）自在となっている。一方、第１の挟持部２１は、貫通部において足場体５に固定されており、第１の挟持部２１の外面に当接するストッパ５２が足場体５に設けられている。   The scaffold body 5 has a threaded portion 51 formed at the end opposite to the side on which the foot is placed, penetrating through the central portions of the sandwiching portions 21 and 22. That is, it is in the shape of a round bar made of steel and has a threaded portion 51 formed at one end, and this threaded portion 51 penetrates both the sandwiching portions 21 and 22 to the outer surface of the second sandwiching portion 22 (the opposite surface on the one piece portion 102 side). ). Further, the insertion hole 22a of the second clamping part 22 through which the screw part 51 penetrates has a large truncated cone shape on the outer surface side, and has a gap between the screw part 51, as shown in FIGS. As shown, the second clamping part 22 is movable (swingable). On the other hand, the first sandwiching portion 21 is fixed to the scaffold body 5 at the penetrating portion, and a stopper 52 that contacts the outer surface of the first sandwiching portion 21 is provided on the scaffold body 5.

そして、回転体６をネジ部５１に締め込むことで、両挟持部２１、２２で一片部１０２が挟持される。すなわち、回転体６は、図５、図６に示すように、ナット６１とハンドル６２とが一体化したもので、第２の挟持部２２から突出したネジ部５１に、ハンドル６２を手で回してナット６１を締め込むことで、両挟持部２１、２２で一片部１０２が挟持されて、足場体５つまり昇降用ステップ１が主柱材１０１に固定される。一方、回転体６を緩めると、図３に示すように、バネ材２４によって昇降用ステップ１が主柱材１０１に仮保持され、挟持体２を一片部１０２から引き抜けば昇降用ステップ１を取り外せるものである。ここで、ハンドル６２は、手で回しても所定の力・トルクでナット６１を締め込める形状に形成されている。   And the one piece part 102 is clamped by both the clamping parts 21 and 22 by tightening the rotary body 6 in the screw part 51. That is, as shown in FIGS. 5 and 6, the rotating body 6 is formed by integrating a nut 61 and a handle 62, and the handle 62 is manually turned around the screw portion 51 protruding from the second clamping portion 22. By tightening the nut 61, the one piece portion 102 is held between the holding portions 21 and 22, and the scaffold body 5, that is, the lifting step 1 is fixed to the main column member 101. On the other hand, when the rotating body 6 is loosened, as shown in FIG. 3, the lifting step 1 is temporarily held by the main column member 101 by the spring material 24, and if the clamping body 2 is pulled out from the one piece portion 102, the lifting step 1 is performed. It can be removed. Here, the handle 62 is formed in such a shape that the nut 61 can be tightened with a predetermined force and torque even if it is turned by hand.

この実施の形態によれば、実施の形態１と同様に、昇降用ステップ１を工具を使わずに、かつ片手で着脱することが可能で、容易かつ安定して安全に、しかも、任意の位置に足場を送電線鉄塔に着脱することが可能となる。また、バネ材５の弾性力によって両挟持部２１、２２で一片部１０２を仮挟持するため、挟持体２（昇降用ステップ１）を一片部１０２により確実に仮保持することが可能となる。また、足場体５の端部のネジ部５１に回転体６を締め込んで、両挟持部２１、２２で一片部１０２を挟持するため、挟持体２を一片部１０２により強固に固定することが可能となり、その結果、足場としての安定性、安全性が向上する。   According to this embodiment, as in the first embodiment, the lifting step 1 can be attached and detached with one hand without using a tool, easily, stably and safely, and at any position. In addition, the scaffold can be attached to and detached from the transmission line tower. Moreover, since the one piece part 102 is temporarily clamped by the both clamping parts 21 and 22 by the elastic force of the spring material 5, the clamping body 2 (step 1 for raising / lowering) can be reliably temporarily held by the one piece part 102. In addition, since the rotating body 6 is fastened to the screw portion 51 at the end of the scaffold body 5 and the one piece portion 102 is held by the both holding portions 21 and 22, the holding body 2 can be firmly fixed by the one piece portion 102. As a result, stability and safety as a scaffold are improved.

（実施の形態４）
図７は、この実施の形態に係る昇降用ステップ１を示す（ａ）平面図と（ｂ）正面図である。この実施の形態では、支持部７を備える点で実施の形態１、２と構成が異なり、実施の形態１、２と同等の構成については、同一符号を付することでその説明を省略する。 (Embodiment 4)

この支持部７は、挟持体２に下方に延びて設けられ、足場体４に人の足が載せられた際に、主柱材１０１に当接することで足場体４の撓みを抑制するものである。すなわち、平面形状が略コ字状の挟持体２の第１の挟持部２１の内面２１ａ側に磁石３１が設けられ、第２の挟持部２２に形成されたネジ孔２２ｂに、ネジ棒状の締付バー（回転体）８が貫通して螺合されている。ここで、締付バー８の一端部（主柱材１０１側の端部）には円盤状の押圧部８１が設けられ、他端部には、ハンドル８２がスライド自在に設けられている。   The support portion 7 is provided to extend downward on the sandwiching body 2 and suppresses the bending of the scaffold body 4 by contacting the main pillar material 101 when a human foot is placed on the scaffold body 4. is there. That is, the magnet 31 is provided on the inner surface 21a side of the first clamping part 21 of the clamping body 2 having a substantially U-shaped planar shape, and the screw hole 22b formed in the second clamping part 22 is screwed in the shape of a screw rod. A bar (rotating body) 8 is threaded through. Here, a disc-shaped pressing portion 81 is provided at one end portion (end portion on the main column member 101 side) of the fastening bar 8, and a handle 82 is slidably provided at the other end portion.

また、第１の挟持部２１の外側面に足場体４が設けられ、この足場体４と直交するように、第１の挟持部２１の下面から支持部７が下方に延びて設けられている。この支持部７は、略直方体状で、足場体４に人の足などが載せられていない状態では、一片部１０２にわずかに接しているか、一片部１０２からわずかに離れるように形成されている。また、支持部７の長さ、厚みは、足場体４の撓みをより抑制できるように設定されている。   Further, the scaffold body 4 is provided on the outer surface of the first sandwiching portion 21, and the support portion 7 is provided extending downward from the lower surface of the first sandwiching portion 21 so as to be orthogonal to the scaffold body 4. . The support portion 7 has a substantially rectangular parallelepiped shape, and is formed so as to be slightly in contact with the one piece portion 102 or slightly away from the one piece portion 102 when a human foot or the like is not placed on the scaffold body 4. . Moreover, the length and thickness of the support part 7 are set so that the bending of the scaffold body 4 can be suppressed more.

そして、挟持部２１、２２間に一片部１０２を挿入すると、磁石３１の磁力によって第１の挟持部２１が一片部１０２に付着し、締付バー８を締め込むと、締付バー８と第１の挟持部２１とで一片部１０２が挟持されて、昇降用ステップ１が主柱材１０１に取り付けられる。この状態で足場体４に人の足などが載せられると、支持部７に矢印Ｄ方向のモーメントが生じて、支持部７が主柱材１０１に当接（押圧）する。これにより、支持部７が主柱材１０１で支持されて、足場体４が下方に撓むのが抑制される。   When the one piece portion 102 is inserted between the holding portions 21 and 22, the first holding portion 21 adheres to the one piece portion 102 by the magnetic force of the magnet 31, and when the tightening bar 8 is tightened, One piece portion 102 is held by one holding portion 21, and the elevating step 1 is attached to the main column 101. When a human foot or the like is placed on the scaffold body 4 in this state, a moment in the direction of arrow D is generated in the support portion 7, and the support portion 7 abuts (presses) the main pillar material 101. Thereby, the support part 7 is supported by the main pillar material 101, and it is suppressed that the scaffold body 4 bends below.

このような実施の形態によれば、足場体４に人の足などが載せられた際に、支持部７によって足場体４の撓みが抑制されるため、足場としての安定性、安全性が向上する。   According to such an embodiment, when a human foot or the like is placed on the scaffold body 4, the support section 7 suppresses the bending of the scaffold body 4, so that stability and safety as a scaffold are improved.
