Description
本発明は、門扉用車輪に関する。さらに詳しくは、地面に敷設されたガイドレール上を自走することができる電動門扉に用いられる門扉用車輪に関する。 The present invention relates to a gate wheel. More specifically, the present invention relates to a gate wheel used for an electric gate that can be self-propelled on a guide rail laid on the ground.
近年、門幅の広い出入り口に設置される門扉には、電動移動柱にモーターを設け、このモーターで電動移動柱下部に設けた車輪を駆動することにより、地面に施設されたガイドレール上を自走できるようにした電動門扉が広く採用されている。

しかるに、ステンレス車輪は、雨天時などにガイドレールや車輪が濡れるとスリップしやすくなり、ひいては門扉の開閉ができなくなるという問題があった。
また、材料費が高く、生産コストが高いという問題があった。
In recent years, gates installed at wide entrances and exits are equipped with motors on electric moving columns, and the motors on the lower side of the electric moving columns are driven by these motors, so that the guide rails installed on the ground can be driven automatically. Electric gates that can run are widely used.
Conventionally, stainless steel wheels manufactured by cutting out stainless steel have been used as wheels used for the electric gates.
However, the stainless steel wheels are prone to slip when the guide rails or wheels get wet in rainy weather, and as a result, the gate cannot be opened or closed.
In addition, the material cost is high and the production cost is high.

And the flange, wheel, and metal board are integrally fixed.
Since the wheel portion is made of rubber and has high friction, even when the guide rail or wheel gets wet during rainy weather, it is difficult to slip and the gate can be opened and closed reliably. In addition, material costs are low and production costs can be reduced.
しかるに、一般に、電動門扉の電動移動柱はモーターなどの駆動機構が備わっているため重く、特許文献１の門扉用車輪では、長時間門扉を動かさない場合には、電動移動柱
の重量でゴム製車輪部が変形し、その変形がすぐには戻らないという問題がある。
変形した状態の車輪を駆動し門扉を動かそうとすると、変形した形状のままで車輪が回転するので、門扉を円滑に開閉できなかったり、門扉の震動により騒音が発生したりするという問題がある。
However, in general, the electric moving column of the electric gate is heavy because it is equipped with a driving mechanism such as a motor. In the gate wheel of Patent Document 1, when the gate is not moved for a long time, the electric moving column is
There is a problem that the rubber wheel part is deformed by the weight of and the deformation does not return immediately.
If you try to move the gate by driving the deformed wheel, the wheel will rotate with the deformed shape, and there is a problem that the gate cannot be opened and closed smoothly or noise is generated due to the vibration of the gate. .

According to the first invention, since the rubber wheel portion and the hard wheel portion have substantially the same diameter, the weight of the electric moving column can be supported by the hard wheel portion, and the electric moving column can be supported without moving the gate for a long time. The rubber wheel is not deformed by weight. Therefore, there is no possibility that the gate cannot be opened and closed smoothly or noise is generated due to vibration of the gate. Further, since the rubber wheel portion is made of rubber and has high friction, even when the guide rail or wheel gets wet during rainy weather, it is difficult to slip and the gate can be opened and closed reliably.

According to the sixth aspect, since the movement of the wheel in the lateral direction can be restricted by the flange coming into contact with the guide rail, it is possible to prevent the wheel from derailing from the guide rail.
つぎに、本発明の実施形態を図面に基づき説明する。 Next, an embodiment of the present invention will be described with reference to the drawings.
（第１実施形態）
図１および図２に示すように、本発明の第１実施形態に係る門扉用車輪Ａは、主にゴム車輪部１０とステンレス車輪部２０とフランジ３０からなる。ゴム車輪部１０およびステンレス車輪部２０はともに円盤状の車輪であり、略同径となっている。本実施形態におけるステンレス車輪部２０は特許請求の範囲に記載の「硬質車輪部」に相当する。本明細書において、「略同径」の意味は、走行に問題となる変形がゴム車輪部に生じない程度の異なる径を含む意味である。
(First embodiment)
As shown in FIGS. 1 and 2, the gate wheel A according to the first embodiment of the present invention mainly includes a rubber wheel portion 10, a stainless wheel portion 20, and a flange 30. The rubber wheel part 10 and the stainless steel wheel part 20 are both disk-like wheels and have substantially the same diameter. The stainless steel wheel portion 20 in the present embodiment corresponds to a “hard wheel portion” recited in the claims. In the present specification, the meaning of “substantially the same diameter” is meant to include different diameters to such an extent that deformation causing problems in running does not occur in the rubber wheel portion.
フランジ３０はステンレスで形成されており、これも円盤状であるが、ゴム車輪部１０、ステンレス車輪部２０に比べて径が大きくなっている。 The flange 30 is made of stainless steel, which is also disk-shaped, but has a larger diameter than the rubber wheel portion 10 and the stainless steel wheel portion 20.
ゴム車輪部１０、ステンレス車輪部２０、フランジ３０は側面の４か所の同位置にネジ孔４０が設けられており、このネジ孔４０にネジ４１を螺着することで、それらの中心軸を同一として接合されている。
すなわち、ゴム車輪部１０とステンレス車輪部２０とで１つの車輪を構成し、その車輪の側面にフランジ３０が設けられて門扉用車輪Ａが形成されている。
The rubber wheel part 10, the stainless steel wheel part 20, and the flange 30 are provided with screw holes 40 at the same positions on the four sides, and by screwing screws 41 into the screw holes 40, their central axes can be adjusted. They are joined as the same.
That is, the rubber wheel portion 10 and the stainless wheel portion 20 constitute one wheel, and a flange 30 is provided on the side surface of the wheel to form the gate wheel A.
図３に示すように、門扉用車輪Ａは図示しない電動門扉の電動移動柱の車軸Ｓに取り付けられ、ガイドレールＲ上を転がるように設置される。
門扉用車輪Ａの中心軸には、軸孔５０が設けられており、この軸孔５０に車軸Ｓを取り付けることが可能となっている。軸孔５０は円形断面の一部を平坦にした断面Ｄ字状をしており、この断面Ｄ字状の軸孔５０に一致する形状の車軸Ｓを嵌合することで、車軸Ｓに対して門扉用車輪Ａを回転不可能に取り付けることができる。
本実施形態では、軸孔５０を断面Ｄ字状としたが、これに限られず、門扉用車輪Ａと車軸Ｓとの締結をキーやスプラインなどで行ってもよい。
As shown in FIG. 3, the gate wheel A is attached to an axle S of an electric moving column of an electric gate (not shown) and is installed so as to roll on the guide rail R.
A shaft hole 50 is provided in the central axis of the door wheel A, and the axle S can be attached to the shaft hole 50. The shaft hole 50 has a D-shaped cross section in which a part of the circular cross section is flattened. By fitting the axle S having a shape matching the shaft hole 50 having the D cross section, the shaft hole 50 is fitted to the axle S. The door wheel A can be mounted in a non-rotatable manner.
In the present embodiment, the shaft hole 50 has a D-shaped cross section. However, the present invention is not limited to this, and the gate wheel A and the axle S may be fastened with a key or a spline.
電動門扉においては、電動移動柱に設けられたモーターで車軸にトルクを与え、そのトルクを車輪を介してガイドレールに伝えることで走行を行う。そのため、門扉用車輪Ａと車軸Ｓとを回転不可能に取り付けることで、車軸Ｓのトルクを門扉用車輪Ａに伝えることができる。また、前述のネジ４１はゴム車輪部１０とステンレス車輪部２０を貫通して挿入されているため、車軸Ｓから伝わったトルクを分散してゴム車輪部１０とステンレス車輪部２０とが一体となって回転運動することができる。 In the electric gate, the vehicle is driven by applying torque to the axle by a motor provided on the electric moving column and transmitting the torque to the guide rail through the wheels. Therefore, the torque of the axle S can be transmitted to the door wheel A by attaching the door wheel A and the axle S so as not to rotate. Further, since the aforementioned screw 41 is inserted through the rubber wheel portion 10 and the stainless steel wheel portion 20, the torque transmitted from the axle S is dispersed and the rubber wheel portion 10 and the stainless steel wheel portion 20 are integrated. Can be rotated.
門扉用車輪Ａをモーターのトルクを伝達する駆動軸の車輪として用いない場合は、門扉用車輪Ａと車軸Ｓとの間に軸受けを設けて、回転自在に締結してもよい。 When the gate wheel A is not used as the wheel of the drive shaft for transmitting the torque of the motor, a bearing may be provided between the gate wheel A and the axle S, and the gate wheel A may be fastened.
なお、ゴム車輪部１０には、天然ゴムや合成ゴムなどの摩擦係数の高い材質が用いられる。 The rubber wheel portion 10 is made of a material having a high friction coefficient such as natural rubber or synthetic rubber.
また、本発明において、硬質車輪部の材質はステンレスに限られず、電動門扉における電動移動柱の重量を支えることができる硬質の材質であればよい。硬質車輪部が支えるべき重量によって、他の金属や硬質の樹脂などを選択することができる。 In the present invention, the material of the hard wheel portion is not limited to stainless steel, but may be a hard material that can support the weight of the electric moving column in the electric gate. Other metals or hard resins can be selected depending on the weight that the hard wheel portion should support.
以上のような構成であるので、ゴム車輪部１０とステンレス車輪部２０は一体となりガイドレールＲに接する。これにより、ステンレス車輪部２０で電動移動柱の重量を支えることができる。一方、ゴム車輪部１０は電動移動柱の重量を支える必要がなく、駆動力をガイドレールＲに伝える役割を担う。すなわち、ステンレス車輪部２０は鉛直方向にかかる電動移動柱の重量を支え、ゴム車輪部１０は車軸Ｓから伝わるトルクをガイドレールＲに伝え水平方向の駆動力に変換するのである。 Since it is the above structures, the rubber wheel part 10 and the stainless steel wheel part 20 are united, and contact the guide rail R. Thereby, the weight of the electric moving column can be supported by the stainless steel wheel portion 20. On the other hand, the rubber wheel portion 10 does not need to support the weight of the electric moving column and plays a role of transmitting the driving force to the guide rail R. That is, the stainless steel wheel portion 20 supports the weight of the electric moving column applied in the vertical direction, and the rubber wheel portion 10 transmits the torque transmitted from the axle S to the guide rail R and converts it into a horizontal driving force.
ゴム車輪部１０は電動移動柱の重量により変形することはないので、たとえ長時間門扉を動かさないとしても、ゴム車輪部１０が変形して元の形状に戻らないということがない。そのため、門扉を円滑に開閉できなかったり、門扉の振動により騒音が発生したりする恐れがない。 Since the rubber wheel portion 10 is not deformed by the weight of the electric moving column, the rubber wheel portion 10 is not deformed and does not return to its original shape even if the gate is not moved for a long time. Therefore, there is no fear that the gate cannot be opened and closed smoothly or noise is generated due to vibration of the gate.
また、ゴム車輪部１０はゴムで形成されており摩擦が高いため、雨天時などにガイドレールＲや門扉用車輪Ａが濡れた場合でもスリップし難く、確実に門扉の開閉を行うことができる。 Further, since the rubber wheel portion 10 is made of rubber and has high friction, even when the guide rail R or the gate wheel A is wet in rainy weather, it is difficult to slip, and the gate can be opened and closed reliably.
門扉用車輪Ａに設けられたフランジ３０はガイドレールＲの側面に接触し、門扉用車輪Ａの横方向の動きを制限する。フランジ３０により、門扉用車輪ＡがガイドレールＲから脱線することを防ぐことができる。 The flange 30 provided on the gate wheel A contacts the side surface of the guide rail R and restricts the lateral movement of the gate wheel A. The flange 30 can prevent the gate wheel A from derailing from the guide rail R.
また、図１から図３に示すように、ゴム車輪部１０の外周には、その中心軸と平行に多数の溝１１が形成されている。
この多数の溝１１により、ゴム車輪部１０の摩擦を高めることができ、効率よくガイドレールに駆動力を伝えることができる。また、雨天時などにガイドレールＲや門扉用車輪Ａが濡れた場合に、溝１１をつたって排水することができるため、よりスリップし難く、確実に門扉の開閉を行うことができる。
Further, as shown in FIGS. 1 to 3, a large number of grooves 11 are formed on the outer periphery of the rubber wheel portion 10 in parallel with the central axis.
The large number of grooves 11 can increase the friction of the rubber wheel portion 10 and can efficiently transmit the driving force to the guide rail. Further, when the guide rail R and the gate wheel A are wet in rainy weather or the like, the drainage can be made through the groove 11, so that it is difficult to slip and the gate can be opened and closed reliably.
（引張荷重測定）
つぎに、門扉用車輪Ａと従来のステンレス車輪およびゴム車輪の引張荷重の測定について説明する。
(Tensile load measurement)
Next, the measurement of the tensile load of the gate wheel A and the conventional stainless steel wheels and rubber wheels will be described.
引張荷重の測定は、図５に示すように、バネ秤の一端を電動移動柱に紐で結びつけ、他端を試験者が持ち、電動移動柱を閉方向に動かして、電動移動柱の引張力をバネ秤で測定することで行った。引張荷重とは、電動移動柱がガイドレール上を自走する時の水平方向の力の大きさを意味する。
測定は、ガイドレールを水没状態として、電動移動柱の車輪を門扉用車輪Ａ、ステンレス車輪、ゴム車輪に変更し、さらに電動移動柱内に積み込む錘の数を変更して、それぞれの条件で行った。なお、本測定において電動移動柱の重量は３０kg、錘は１つあたり１０kgのものを用いた。また、各条件において電動移動柱の車輪がスリップした時と、スリップから復帰する時の引張荷重を測定した。
As shown in FIG. 5, the tensile load is measured by connecting one end of the spring balance to the electric moving column with a string, holding the other end by the tester, moving the electric moving column in the closing direction, and pulling the tensile force of the electric moving column. Was measured with a spring balance. A tensile load means the magnitude | size of the force of a horizontal direction when an electrically-driven movable column self-propels on a guide rail.
The measurement is performed under each condition with the guide rail submerged, the wheel of the electric moving column changed to the gate wheel A, stainless steel wheel, and rubber wheel, and the number of weights loaded in the electric moving column is changed. It was. In this measurement, an electric moving column having a weight of 30 kg and a weight of 10 kg was used. Moreover, the tensile load when the wheel of the electrically-driven moving column slips and returns from the slip under each condition was measured.
以上の測定により、図６および図７に示す結果が得られた。図７のグラフに示すように、門扉用車輪Ａの引張荷重は、すべての条件において、ゴム車輪と比較して小さいが、ステンレス車輪と比較して大きい。
前述のとおり、ゴム車輪は電動移動柱を長時間動かさないと変形するという問題があり、ステンレス車輪は滑りやすい（引張荷重が小さい）という問題がある。以上のことを考慮すれば、ステンレス車輪よりも滑りにくく（引張荷重が大きく）、長時間動かさない場合でも変形することのない門扉用車輪Ａは門扉用車輪として好適である。
With the above measurement, the results shown in FIGS. 6 and 7 were obtained. As shown in the graph of FIG. 7, the tensile load of the gate wheel A is smaller than the rubber wheel but larger than the stainless steel wheel in all conditions.
As described above, the rubber wheel has a problem that it deforms unless the electric moving column is moved for a long time, and the stainless steel wheel has a problem that it is slippery (the tensile load is small). Considering the above, the gate wheel A that is less slippery (has a larger tensile load) than the stainless steel wheel and does not deform even when it does not move for a long time is suitable as a gate wheel.
（他の実施形態）
第１実施形態に係る門扉用車輪Ａには、その側面にフランジ３０が設けられているが、フランジ３０を設けない実施形態としてもよい。
図４（Ｂ）に示すように、門扉用車輪Ｂは門扉用車輪Ａにおいてフランジ３０が設けられていない構成をしている。その余の構成は門扉用車輪Ａと同様であるので説明を省略する。
電動門扉に、フランジ３０以外の方法でガイドレールＲからの脱線を防ぐ処置が施されている場合、あるいはガイドレールＲではなく、地面を直接走行する場合に好適である。
(Other embodiments)
The gate wheel A according to the first embodiment is provided with the flange 30 on the side surface, but the flange 30 may not be provided.
As shown in FIG. 4B, the gate wheel B has a configuration in which the flange 30 is not provided in the gate wheel A. Since the remaining structure is the same as that of the gate wheel A, the description thereof is omitted.
This is suitable when the electric gate is treated to prevent derailment from the guide rail R by a method other than the flange 30, or when the electric gate is traveling directly on the ground instead of the guide rail R.
図４（Ｃ）に示す門扉用車輪Ｃは、ゴム車輪部１０を中央とし、そのゴム車輪部１０を２つのステンレス車輪部２０で挟んだ構成をしている。その余の構成は門扉用車輪Ａと同様であるので説明を省略する。
前述のとおり、ステンレス車輪部２０は鉛直方向にかかる電動移動柱の重量を支える役割を担うが、ステンレス車輪部２０が車輪の両側にあるので、電動移動柱の重量をバランスよく支えることができる。
なお、本実施形態の場合、フランジ３０側に位置するステンレス車輪２０と、フランジ３０を同一部材として形成することで、部品点数が少なくなり、生産コストを抑えることができる。
A gate wheel C shown in FIG. 4C has a configuration in which the rubber wheel portion 10 is centered and the rubber wheel portion 10 is sandwiched between two stainless steel wheel portions 20. Since the remaining structure is the same as that of the gate wheel A, the description thereof is omitted.
As described above, the stainless steel wheel portion 20 plays a role of supporting the weight of the electric moving column in the vertical direction. However, since the stainless wheel portion 20 is on both sides of the wheel, the weight of the electric moving column can be supported in a balanced manner.
In the case of this embodiment, by forming the stainless steel wheel 20 located on the flange 30 side and the flange 30 as the same member, the number of parts is reduced, and the production cost can be suppressed.
図４（Ｄ）に示す門扉用車輪Ｄは、ステンレス車輪部２０を中央とし、そのステンレス車輪部２０を２つのゴム車輪部１０で挟んだ構成をしている。その余の構成は門扉用車輪Ａと同様であるので説明を省略する。
前述のとおり、ゴム車輪部１０は車軸Ｓから伝わるトルクを水平方向の駆動力に変換する役割を担うが、ゴム車輪部１０が車輪の両側にあるので、ガイドレールＲにバランスよく駆動力を伝えることができる。
A gate wheel D shown in FIG. 4 (D) has a configuration in which the stainless steel wheel portion 20 is centered and the stainless steel wheel portion 20 is sandwiched between two rubber wheel portions 10. Since the remaining structure is the same as that of the gate wheel A, the description thereof is omitted.
As described above, the rubber wheel portion 10 plays a role of converting the torque transmitted from the axle S into a horizontal driving force. However, since the rubber wheel portion 10 is on both sides of the wheel, the driving force is transmitted to the guide rail R in a balanced manner. be able to.
以上の実施形態の他にも、ゴム車輪部１０とステンレス車輪部２０とで多層構造にした実施形態としてもよい。ただし、第１実施形態に係る門扉用車輪Ａのように、単純な構成とすれば、生産が容易で、生産コストを抑えることができる。 In addition to the above-described embodiment, a multi-layer structure may be used with the rubber wheel portion 10 and the stainless wheel portion 20. However, if it is set as a simple structure like the gate wheel A according to the first embodiment, the production is easy and the production cost can be suppressed.
本発明に係る門扉用車輪は、電動門扉の電動移動柱の車輪として用いられる。その電動門扉はアコーディオン式、引き戸式などの区別なく利用することができる。 The gate wheel according to the present invention is used as a wheel of an electric moving column of an electric gate. The electric gate can be used without distinction between accordion type and sliding door type.
