　一方、空気調和機では、特許文献２に、筐体を持ち上げなくても容易に移動できるように、筐体の底部にキャスター輪を取り付け、取り扱いの利便性を向上させた構造が開示されている。また、特許文献３には、筐体の後面側下部に一対のキャスター輪を左右に取り付け、後面側上部に把手を設け、把手を持って筐体を後側に傾けた状態でキャスター輪により移動できるようにし、簡便な移動を可能とした空気調和機が開示されている。尚、特許文献２、３に記載のキャスター輪は、ロック機構を備えていない。 On the other hand, for an air conditioner, Patent Document 2 discloses a structure in which a caster wheel is attached to the bottom of a casing so that the convenience of handling is improved so that the casing can be easily moved without lifting the casing. . In Patent Document 3, a pair of caster wheels are attached to the left and right lower parts of the rear surface of the housing, a handle is provided on the upper rear surface, and the housing is moved by the caster wheels with the handle tilted to the rear side. An air conditioner has been disclosed that enables it to be moved easily. Note that the caster wheels described in Patent Documents 2 and 3 do not include a lock mechanism.

　特許文献１に記載の従来の車輪装置では、ロック機構が、車輪の内側面の環状の凹部に形成したロック用の内歯や、ロック用の内歯に噛み合うロック歯部などで構成されているため、複雑な構造の部品が必要であり、コストも高くなるという問題がある。 In the conventional wheel device described in Patent Document 1, the lock mechanism is configured by a lock internal tooth formed in an annular recess on the inner surface of the wheel, a lock tooth portion meshing with the lock internal tooth, or the like. Therefore, there is a problem that parts having a complicated structure are necessary and the cost is increased.
　本発明は、上述したような事情に鑑みてなされたものであり、比較的簡素な構造のロック機構でありながら安定したロック性能が得られる車輪装置、及び、該車輪装置を取り付けた空気調和機を提供することを目的とする。 The present invention has been made in view of the circumstances as described above, and is a wheel device capable of obtaining a stable locking performance while being a lock mechanism having a relatively simple structure, and an air conditioner having the wheel device attached thereto. The purpose is to provide.
　本発明に係る車輪装置は、車輪と、該車輪の側面に対向配置された制動片とを備えた車輪装置において、前記制動片は、前記車輪の軸方向に対して傾斜した被操作面を前記車輪とは反対側に有し、前記車輪の軸方向に変位可能であり、前記車輪の軸方向と交差する方向に移動して前記被操作面に当接し、前記制動片を前記車輪の側面に圧接する位置まで変位させるロック操作、及び、前記被操作面に当接又は離間して前記制動片を前記車輪の側面に接触しない位置に変位させるロック解除操作が可能な操作体を備えていることを特徴とする。 The wheel device according to the present invention is a wheel device including a wheel and a braking piece disposed opposite to a side surface of the wheel, wherein the braking piece has an operated surface inclined with respect to an axial direction of the wheel. It is on the opposite side of the wheel, is displaceable in the axial direction of the wheel, moves in a direction crossing the axial direction of the wheel, abuts on the operated surface, and the braking piece is placed on the side surface of the wheel. An operation body capable of a lock operation for displacing to a position to be pressed and a lock release operation for displacing the brake piece to a position not contacting the side surface of the wheel by contacting or separating from the operated surface. It is characterized by.
　本発明においては、操作体を車輪の軸方向と交差する方向の一方に移動して、車輪の側面に対向配置された制動片が車輪の反対側に有する被操作面に当接させると、該被操作面は車輪の軸方向に対して傾斜しているので、制動片を操作体の当接により車輪の側面に圧接する位置まで車輪の軸方向に変位させ、車輪の回転をロックすることができる。このロック状態から操作体を被操作面に当接したまま又は被操作面から離間するまで車輪の軸方向と交差する方向の他方に移動して、制動片を車輪の軸方向に車輪の側面と接触しない位置に変位させ、車輪の回転のロックを解除することができる。上記ロック状態で車輪に回転力が加わった場合、車輪の回転力は車輪の側面に接触している制動片には伝わるが、操作体に伝わらないので、操作体が移動して車輪のロック状態が解除されることはない。 In the present invention, when the operating body is moved in one of the directions intersecting with the axial direction of the wheel and the braking piece arranged opposite to the side surface of the wheel is brought into contact with the operated surface on the opposite side of the wheel, Since the operated surface is inclined with respect to the axial direction of the wheel, it is possible to displace the braking piece in the axial direction of the wheel to a position where it is pressed against the side surface of the wheel by the contact of the operating body to lock the rotation of the wheel. it can. From this locked state, the operating body is moved to the other of the directions intersecting with the axial direction of the wheel until the operating body is in contact with the operated surface or separated from the operated surface, and the braking piece is moved to the side surface of the wheel in the axial direction of the wheel. The wheel can be displaced to a position where it does not come into contact, and the rotation of the wheel can be unlocked. When a rotational force is applied to the wheel in the above locked state, the rotational force of the wheel is transmitted to the braking piece that is in contact with the side surface of the wheel, but not transmitted to the operating body. Will not be released.
　本発明に係る車輪装置は、前記操作体は、前記車輪の回転軸に回転自在に支持され、該回転軸回りの回転に伴い前記被操作面に当接及び離間可能であることを特徴とする。
　本発明においては、車輪の回転軸に回転自在に支持された操作体を該回転軸回りの一方側に回転し、操作体を制動片の被操作面に当接させ、制動片を操作体の当接により車輪の側面に圧接する位置まで車輪の軸方向に変位させて、車輪の回転をロックする。このロック状態から操作体を被操作面に当接したまま又は被操作面から離間するまで車輪の回転軸回りの他方側に回転して、制動片を車輪の軸方向に車輪の側面と接触しない位置に変位させ、車輪の回転のロックを解除する。従って、操作体の支持のために車輪の回転軸を利用するので、部品点数が削減され、コストも低減される。 The wheel device according to the present invention is characterized in that the operating body is rotatably supported by a rotating shaft of the wheel, and can be brought into contact with and separated from the operated surface with rotation around the rotating shaft. .

The wheel is displaced in the axial direction to a position where it comes into pressure contact with the side surface of the wheel by contact, and the rotation of the wheel is locked. From this locked state, the operating body is rotated to the other side around the rotation axis of the wheel until it is in contact with the operated surface or separated from the operated surface, and the braking piece does not contact the side surface of the wheel in the axial direction of the wheel. Displace to position and unlock wheel rotation. Therefore, since the rotating shaft of the wheel is used to support the operating body, the number of parts is reduced and the cost is also reduced.
　本発明に係る車輪装置は、前記制動片は、前記車輪の両側面に夫々対向するように２つ配置され、各制動片の前記被操作面は前記車輪の軸方向に対して反対側に傾斜し、前記操作体は、各制動片の前記被操作面に当接及び離間可能な２つの当接部を有していることを特徴とする。 In the wheel device according to the present invention, two braking pieces are arranged so as to face both side surfaces of the wheel, and the operated surface of each braking piece is inclined to the opposite side with respect to the axial direction of the wheel. The operating body includes two abutting portions that can abut and separate from the operated surface of each brake piece.
　本発明においては、操作体を車輪の軸方向と交差する方向の一方に移動させると、操作体が有する２つの当接部の夫々が車輪の両側面に夫々対向配置された２つの制動片の被操作面、即ち車輪の軸方向に対して反対側に傾斜した各被操作面に当接し、各制動片は車輪の軸方向に変位して車輪の各側面に接触し、車輪の回転を両側面でロックする。このロック状態から操作体を２つの当接部の夫々が各制動片の被操作面に当接したまま又は被操作面から離間するまで車輪の軸方向と交差する方向の他方に移動させ、車輪の回転のロックを解除する。従って車輪を両側から挟むように車輪の両側面に夫々制動片を接触させて回転をロックするので、より安定したロック性能が得られる。 In the present invention, when the operating body is moved in one of the directions crossing the axial direction of the wheel, the two brake pieces in which the two abutting portions of the operating body are respectively arranged opposite to the both side surfaces of the wheel. Abuts on the operated surface, that is, each operated surface inclined to the opposite side with respect to the wheel axial direction, and each brake piece is displaced in the wheel axial direction to contact each side surface of the wheel, thereby rotating the wheel on both sides.

　本発明においては、車輪の回転軸を回転自在に支持し、車輪の上側を覆うハウジングと一体に形成した制動片の基端部がハウジングに支持され、基端部から車輪の側面に沿うように延出し、前記被操作面を備えた制動部が前記操作体の当接により車輪の軸方向に変位して車輪の側面と接触し、また制動部が前記操作体と当接したまま又は離間して車輪の側面と接触しなくなる。従って、車輪の側面に沿うように延出した制動片の制動部が車輪の軸方向に変位し易い状態で基端部がハウジングに支持されると共に、制動片をハウジングに成形等により一体にすることにより、部品点数が削減され、コストも低減される。 In the present invention, the rotating shaft of the wheel is rotatably supported, and the base end portion of the braking piece formed integrally with the housing covering the upper side of the wheel is supported by the housing, so that the base end portion follows the side surface of the wheel. The braking portion that extends and the operating surface is displaced in the axial direction of the wheel by the contact of the operating body and contacts the side surface of the wheel, and the braking portion remains in contact with the operating body or is separated. Will not contact the side of the wheel. Accordingly, the base end portion is supported by the housing in a state where the braking portion of the braking piece extending along the side surface of the wheel is easily displaced in the axial direction of the wheel, and the braking piece is integrated with the housing by molding or the like. As a result, the number of parts is reduced and the cost is also reduced.
　本発明に係る空気調和機は、前記車輪装置を筐体の下部に取り付けた空気調和機であって、前記操作体は、前記筐体の側面から突出し、上下方向に変位自在なレバーを有し、該レバーの上下方向の変位に伴い前記被操作面に当接及び離間可能であることを特徴とする。 The air conditioner according to the present invention is an air conditioner in which the wheel device is attached to a lower part of a housing, and the operation body has a lever that protrudes from a side surface of the housing and is vertically displaceable. The lever can be brought into contact with and separated from the operated surface in accordance with the vertical displacement of the lever.
　本発明においては、空気調和機の筐体の下部に前記車輪装置が取り付けられ、筐体の側面から突出したレバーを上下方向に変位させると、操作体が制動片の被操作面に当接及び離間して制動片が車輪の軸方向に変位し、車輪の回転のロック及びロックの解除が行われる。 In the present invention, when the wheel device is attached to the lower part of the casing of the air conditioner and the lever protruding from the side surface of the casing is displaced in the vertical direction, the operating body abuts on the operated surface of the braking piece and The brake pieces are separated and displaced in the axial direction of the wheel, and the rotation of the wheel is locked and unlocked.
　本発明に係る空気調和機は、前記車輪装置は、前記筐体の左右方向に離隔して一対並置され、各車輪装置の車輪の軸方向は前記筐体の前後方向に向いていることを特徴とする。

　従って、左右の各車輪装置の車輪は筐体の左右方向に回転するので、移動を左右方向に制限して移動時の走行安定性を確保すると共に、移動停止時は移動方向である左右方向に離隔した一対の車輪装置をロックし、移動停止時の安定性を向上することができる。 In the air conditioner according to the present invention, a pair of the wheel devices are arranged side by side in the left-right direction of the casing, and the axial direction of the wheel of each wheel device is directed to the front-rear direction of the casing. And

Accordingly, since the wheels of the left and right wheel devices rotate in the left-right direction of the housing, the movement is restricted to the left-right direction to ensure traveling stability during movement, and when the movement is stopped, the left-right direction is the movement direction. A pair of separated wheel devices can be locked to improve the stability when the movement is stopped.
　本発明に係る空気調和機は、前記操作体は、前記レバーの下方向の変位に伴い前記被操作面に当接し、前記レバーは、下方に変位した場合に、載置面に接触可能であることを特徴とする。
　本発明においては、前記レバーを下方向に変位させると、操作体が制動片の被操作面に当接して制動片が車輪の回転をロックし、レバーが載置面に接触する。その結果、制動片が車輪の回転をロックして筐体の移動を防止することに加えて、レバーと載置面との接触によって筐体の移動を抑制することができる。 In the air conditioner according to the present invention, the operating body comes into contact with the operated surface with a downward displacement of the lever, and the lever can contact the mounting surface when displaced downward. It is characterized by that.
In the present invention, when the lever is displaced downward, the operating body comes into contact with the operated surface of the braking piece, the braking piece locks the rotation of the wheel, and the lever contacts the mounting surface. As a result, the brake piece locks the rotation of the wheel to prevent the movement of the casing, and the movement of the casing can be suppressed by the contact between the lever and the mounting surface.

　本発明に係る車輪装置１０は、車輪１と、車輪１の回転軸１ａを回転自在に支持し、車輪１の上側を覆う樹脂製のキャスタハウス４とを備えている。
　車輪１は、樹脂製のホイール１ｂと、ホイール１ｂの外周部を覆うゴム製のタイヤ１ｃとで構成されている。ホイール１ｂの中心には回転軸１ａを通すための貫通穴１ｂ１が開いている。 A wheel device 10 according to the present invention includes a wheel 1 and a resin caster house 4 that rotatably supports a rotating shaft 1 a of the wheel 1 and covers an upper side of the wheel 1.
The wheel 1 includes a resin wheel 1b and a rubber tire 1c that covers the outer periphery of the wheel 1b. At the center of the wheel 1b, a through hole 1b1 for passing the rotating shaft 1a is opened.
　キャスタハウス４は、略半円筒状の外周部４ａと、外周部４ａの両側に位置し、各縁部に連なる略半円板状の２枚の側板４ｂとを有する。両側の側板４ｂの下部中央には、内側にツメ４ｄを有する回転軸保持部４ｃが設けてある。車輪１の回転軸１ａは両端がツメ４ｄで固定され、車輪１は回転軸１ａを中心として回転可能である。 The caster house 4 has a substantially semi-cylindrical outer peripheral portion 4a and two substantially semi-disc-shaped side plates 4b which are located on both sides of the outer peripheral portion 4a and are continuous with each edge portion. A rotating shaft holding portion 4c having a claw 4d on the inside is provided at the lower center of the side plates 4b on both sides. Both ends of the rotating shaft 1a of the wheel 1 are fixed by claws 4d, and the wheel 1 can rotate around the rotating shaft 1a.
　次に、車輪１のロック機構について説明する。
　各側板４ｂは、外周部４ａの両側の同位置に上下方向に帯状の欠落部分４ｅを有する。各欠落部分４ｅには、上端部２ｃを外周部４ａに一体に支持され、車輪１の側面に沿って下向きに延出する板状の制動アーム２が設けてある。車輪１の側面と制動アーム２との間には空間が維持され、制動アーム２は上端部２ｃを基端部として回転軸１ａの軸方向に変位可能である。尚、図２及び図５では、キャスタハウス４の図示を省略している。 Next, the lock mechanism of the wheel 1 will be described.
Each side plate 4b has a strip-like missing portion 4e in the vertical direction at the same position on both sides of the outer peripheral portion 4a. Each missing portion 4e is provided with a plate-like braking arm 2 that is supported integrally with the outer peripheral portion 4a at the upper end portion 2c and extends downward along the side surface of the wheel 1. A space is maintained between the side surface of the wheel 1 and the braking arm 2, and the braking arm 2 can be displaced in the axial direction of the rotary shaft 1 a with the upper end 2 c as a base end. 2 and 5, the caster house 4 is not shown.
　制動アーム２の下端部２ｂの車輪１とは反対側に、回転軸１ａの軸方向及び上下方向に対して傾斜した傾斜面２ａが形成してある。両側の制動アーム２の傾斜面２ａは回転軸１ａの軸方向に対して反対側に傾斜している。具体的には、傾斜面２ａの下側部分と車輪１の側面との距離が上側部分と車輪１の側面との距離よりも短い。尚、図３では、両側の傾斜面２ａが回転軸１ａの軸方向に対して略同角度で反対側に傾斜しているが、回転軸１ａの軸方向に対して異なる角度で反対側に傾斜していてもよい。 An inclined surface 2a that is inclined with respect to the axial direction and the vertical direction of the rotating shaft 1a is formed on the opposite side of the lower end 2b of the braking arm 2 from the wheel 1. The inclined surfaces 2a of the braking arms 2 on both sides are inclined to the opposite side with respect to the axial direction of the rotating shaft 1a. Specifically, the distance between the lower portion of the inclined surface 2 a and the side surface of the wheel 1 is shorter than the distance between the upper portion and the side surface of the wheel 1. In FIG. 3, the inclined surfaces 2a on both sides are inclined to the opposite side at substantially the same angle with respect to the axial direction of the rotating shaft 1a, but are inclined to the opposite side at different angles with respect to the axial direction of the rotating shaft 1a. You may do it.
　平面視で車輪１を囲う略長方形の枠状をなし、両側を車輪１の回転軸１ａに回動自在に支持された枠体３を備えている。車輪１の両側面に面した枠体３の両側の枠部３ｃに、回転軸１ａが挿通される孔３ｄを設けている。各枠部３ｃには、各制動アーム２の略下側に位置し、傾斜面２ａと略同角度に傾斜した傾斜部３ａが設けてある。枠体３の傾斜部３ａとは反対側には、手で操作するためのレバー３ｂが設けてある。 A substantially rectangular frame shape surrounding the wheel 1 in a plan view is provided, and a frame body 3 that is rotatably supported on the rotating shaft 1a of the wheel 1 on both sides is provided. Holes 3d through which the rotating shaft 1a is inserted are provided in the frame portions 3c on both sides of the frame 3 facing both side surfaces of the wheel 1. Each frame portion 3c is provided with an inclined portion 3a that is positioned substantially below each brake arm 2 and is inclined at substantially the same angle as the inclined surface 2a. On the opposite side of the frame 3 from the inclined portion 3a, a lever 3b for manual operation is provided.
　枠体３の傾斜部３ａが持ち上げられていない場合、傾斜部３ａは制動アーム２の傾斜面２ａに当接している（軽く接触している）が、制動アーム２を変位させる力は与えていない。その結果、制動アーム２は車輪１の側面との間に空間を維持しているので、車輪１は回転可能な状態（非ロック状態）にある（図２、図３）。レバー３ｂを押し下げて枠体３を回転軸１ａ回りに回転させると（図５、図６）、枠体３の傾斜部３ａが持ち上げられ、制動アーム２の傾斜面２ａに当接し、制動アーム２の下端部２ｂを内側（車輪１の側面に接近する側）へ押し込んでいく。制動アーム２が内側に押し込まれて、車輪１の側面に圧接されると、制動アーム２と車輪１（タイヤ１ｃ）との間の摩擦抵抗により車輪１がロックされて回転できなくなる。このとき両側の制動アーム２は弾性変形しているので、枠体３は制動アーム２から外側向きに反力を受けている。この反力によって制動アーム２と枠体３との間に摩擦力が発生し、枠体３はロック位置で固定される。尚、枠体３の傾斜部３ａが持ち上げられていないとき、傾斜部３ａが制動アーム２の傾斜面２ａに当接せず離間していてもよい。また、枠体３の傾斜部３ａが持ち上げられていないとき、傾斜部３ａが制動アーム２の傾斜面２ａに当接して制動アーム２を変位させていても、制動アーム２が車輪１の側面に接触しない状態であればよい。 When the inclined portion 3a of the frame 3 is not lifted, the inclined portion 3a is in contact (lightly in contact) with the inclined surface 2a of the braking arm 2, but does not give a force to displace the braking arm 2. . As a result, the brake arm 2 maintains a space between the side surface of the wheel 1 and the wheel 1 is in a rotatable state (unlocked state) (FIGS. 2 and 3). When the lever 3b is pushed down and the frame 3 is rotated around the rotation axis 1a (FIGS. 5 and 6), the inclined portion 3a of the frame 3 is lifted and comes into contact with the inclined surface 2a of the brake arm 2, Is pushed inward (side approaching the side surface of the wheel 1). When the braking arm 2 is pushed inward and pressed against the side surface of the wheel 1, the wheel 1 is locked by the frictional resistance between the braking arm 2 and the wheel 1 (tire 1c) and cannot be rotated. At this time, since the brake arms 2 on both sides are elastically deformed, the frame 3 receives a reaction force from the brake arms 2 outward. This reaction force generates a frictional force between the braking arm 2 and the frame body 3, and the frame body 3 is fixed at the lock position. When the inclined portion 3a of the frame 3 is not lifted, the inclined portion 3a may be separated from the inclined surface 2a of the braking arm 2 without contacting. Further, when the inclined portion 3 a of the frame 3 is not lifted, even if the inclined portion 3 a is in contact with the inclined surface 2 a of the braking arm 2 to displace the braking arm 2, the braking arm 2 is placed on the side surface of the wheel 1. What is necessary is just the state which does not contact.
　本実施の形態１では、ロック時でも枠体３のレバー３ｂは床面（載置面）Ｆには接触していない（図５）。レバー３ｂを床面Ｆに接触させると、床面Ｆに傷がつくおそれがあるため、本実施形態１ではレバー３ｂの可動範囲を図２に示す位置と図５に示す位置との間に制限している。 In the first embodiment, the lever 3b of the frame 3 is not in contact with the floor surface (mounting surface) F even when locked (FIG. 5). If the lever 3b is brought into contact with the floor surface F, the floor surface F may be damaged. Therefore, in the first embodiment, the movable range of the lever 3b is limited between the position shown in FIG. 2 and the position shown in FIG. is doing.
　本実施形態１では、制動アーム２の内側は平面であり、特に加工を加えていないが、車輪１をロックする力を強くするために、制動アーム２の内側に凹凸を設けるなどの加工を加えてもよい。また、制動アーム２の車輪１（タイヤ１ｃ）との接触部にゴム等の摩擦抵抗の大きい部材を貼り付けてもよい。 In the first embodiment, the inside of the braking arm 2 is a flat surface and no particular processing is performed. However, in order to increase the force for locking the wheel 1, processing such as providing unevenness on the inside of the braking arm 2 is added. May be. Moreover, you may affix a member with large frictional resistance, such as rubber | gum, on the contact part with the wheel 1 (tire 1c) of the braking arm 2. FIG.
　上記構成のロック機構により、本発明に係る車輪装置１０を取り付けた機器が例えばロック時に横方向へ押された場合など、車輪１に回転力が加わるときでも、車輪１の回転力は制動アーム２（キャスタハウス４）に伝わるが、枠体３には直接伝わらない。したがって、車輪１に回転力が加わったときでも、枠体３がロックを解除する方向に回転してロックが緩んだり外れたりするということが防止される。これに対し、本発明とは異なり、枠体３が直接車輪１を押さえるような構造にした場合は（間に制動アーム２が存在しない場合）、車輪１に加えられた回転力が直接枠体３に伝わり、枠体３が回転してロックが解除してしまう可能性がある。 Even when a rotational force is applied to the wheel 1 such as when the device to which the wheel device 10 according to the present invention is attached is pushed laterally when locked, the rotational force of the wheel 1 is applied to the braking arm 2. It is transmitted to (caster house 4) but not directly to frame 3. Therefore, even when a rotational force is applied to the wheel 1, it is prevented that the frame 3 is rotated in the unlocking direction and the lock is loosened or detached. On the other hand, unlike the present invention, when the frame 3 is configured to directly press the wheel 1 (when the braking arm 2 does not exist between them), the rotational force applied to the wheel 1 is directly applied to the frame. 3, there is a possibility that the frame 3 rotates and the lock is released.
