FIG. 3 is a plan view and a partially enlarged view of the belt according to the first embodiment. In addition, the cylindrical shape in the present disclosure includes an elongated rod-like object, and the inside is not necessarily empty.
　図１および図２に示すように、保持装置１は、ベルト２、ベルトテーブル３、ナット４、第１の台座５および第２の台座６を備えている。ベルト２は、ナット４を回転させることで上下自在に移動する。このため、ベルト２とベルトテーブル３との間に保持対象物（例えばカメラなどの筒状の物体）を配置した後、ナット４を回転させて筒状の物体をベルトテーブル３に押し付けて保持することができる。 1 and 2, the holding device 1 includes a belt 2, a belt table 3, a nut 4, a first pedestal 5, and a second pedestal 6. The belt 2 moves freely by rotating the nut 4. For this reason, after a holding object (for example, a cylindrical object such as a camera) is disposed between the belt 2 and the belt table 3, the nut 4 is rotated to hold the cylindrical object against the belt table 3. be able to.
　ベルト２は、屈曲性のある材料（例えば熱可塑性ポリエステルエラストマーなど）からなる。図３に示すように、ベルト２のおもて面（保持対象物と接触しない面）側において、ベルト２の両端部における所定の長さの領域２ａ、２ｂにラックねじ７が形成されている。領域２ａ、２ｂのそれぞれの長さは、例えばベルト２の長さの１／５～１／４程度であるが、この範囲内に含まれる必要はなく、適宜設定することができる。また、領域２ａ、２ｂのそれぞれにおいてベルト２の中心に近い側（保持対象物側）の所定位置に、隣接するラックねじ７同士を繋ぐようにストッパー８が形成されている。図３ではストッパー８はベルト２の幅方向（図３における短手方向）の両端部に形成されているが、ストッパー８はベルト２の幅方向のどの位置に形成されていてもよい。また、図２に示すように、ベルト２の裏面（保持対象物と接触する面）側において、ベルト２の両端部に抜け止め（突起）９が形成されている。 The belt 2 is made of a flexible material (for example, a thermoplastic polyester elastomer). As shown in FIG. 3, rack screws 7 are formed in regions 2 a and 2 b having predetermined lengths at both ends of the belt 2 on the side of the front surface of the belt 2 (surface that does not contact the object to be held). . The length of each of the regions 2a and 2b is, for example, about 1/5 to 1/4 of the length of the belt 2, but does not need to be included in this range and can be set as appropriate. Further, a stopper 8 is formed at a predetermined position on the side close to the center of the belt 2 (the holding object side) in each of the regions 2a and 2b so as to connect the adjacent rack screws 7 to each other. In FIG. 3, the stopper 8 is formed at both ends in the width direction of the belt 2 (short direction in FIG. 3), but the stopper 8 may be formed at any position in the width direction of the belt 2. Further, as shown in FIG. 2, retaining (protrusions) 9 are formed at both end portions of the belt 2 on the back surface (surface in contact with the object to be held) side of the belt 2.
　図２に示すように、ベルトテーブル３は、テーブル上部３ａとテーブル下部３ｂとから構成される。テーブル上部３ａは円形状である。テーブル上部３ａは、ベルト２の両端部がそれぞれ挿入される２つのガイド孔１０を有している。ガイド孔１０は、例えば弧状を有する孔部である。テーブル下部３ｂは、水平断面の四角形のうち対向する２辺が弧状を有する筒状の物体である。テーブル下部３ｂの一部（弧状部分の一部）に切り欠き１１を設けている。切り欠き１１は、ベルト２がガイド孔１０を介して上下する際にベルト２の抜け止め９が通過する部分である。テーブル下部３ｂにはビス孔１２を設けている。 As shown in FIG. 2, the belt table 3 includes a table upper part 3a and a table lower part 3b. The table upper part 3a is circular. The table upper portion 3a has two guide holes 10 into which both end portions of the belt 2 are inserted. The guide hole 10 is a hole having an arc shape, for example. The table lower part 3b is a cylindrical object in which two opposing sides of the quadrangle of the horizontal section have an arc shape. A notch 11 is provided in a part of the table lower part 3b (a part of the arc-shaped part). The notch 11 is a portion through which the belt 9 comes off when the belt 2 moves up and down via the guide hole 10. Screw holes 12 are provided in the table lower part 3b.
　ナット４は筒状であり、ナット４の内側に雌ねじ１３を形成している。この雌ねじ１３がベルト２のラックねじ７と係合し、ナット４を回転させることでベルト２は上下自在に移動する。このとき、雌ねじ１３は一条ねじでもよいし、二条ねじでもよい。ナット４の下面（保持対象物側の面）には全周にわたって円周溝１４（図４参照）を形成している。 The nut 4 has a cylindrical shape, and an internal thread 13 is formed inside the nut 4. The female screw 13 engages with the rack screw 7 of the belt 2 and rotates the nut 4 so that the belt 2 moves up and down freely. At this time, the internal thread 13 may be a single thread or a double thread. A circumferential groove 14 (see FIG. 4) is formed on the entire bottom surface of the nut 4 (the surface on the holding object side).
　第１の台座５は、筒状の筒状部５ａと、仕切り部５ｂと、連結部５ｃと、ビス挿入部５ｄとを有している。筒状部５ａには、ビス１６を挿入するビス孔１７が設けられている。筒状部５ａの上面には、全周にわたって頭部１５を形成している。頭部１５がナット４の円周溝１４に嵌りこむことにより、ナット４をベルトテーブル３のテーブル上部３ａと第１の台座５との間に回転可能に保持している。 The first pedestal 5 has a cylindrical cylindrical part 5a, a partition part 5b, a connecting part 5c, and a screw insertion part 5d. The cylindrical portion 5a is provided with a screw hole 17 into which the screw 16 is inserted. A head portion 15 is formed on the entire upper surface of the cylindrical portion 5a. By fitting the head 15 into the circumferential groove 14 of the nut 4, the nut 4 is rotatably held between the table upper portion 3 a of the belt table 3 and the first base 5.
　第２の台座６は、固定部６ａを有している。固定部６ａの下部（筒状部分）の裏面側には雌ねじが設けられており、この雌ねじによって保持装置１を所望の場所に取り付けることができる。固定部６ａは、ビス１６が挿入されるビス孔１９を有している。ビス１６は、第１の台座５のビス孔１７と、ビス挿入部５ｄおよびビス孔１８と、ベルトテーブル３のビス孔１２とを経由して第２の台座６のビス孔１９に固定される。これにより、ビス１６によってベルトテーブル３および第１の台座５が第２の台座６に固定される。 The second pedestal 6 has a fixed portion 6a. A female screw is provided on the back surface side of the lower portion (tubular portion) of the fixing portion 6a, and the holding device 1 can be attached to a desired place by this female screw. The fixing portion 6a has a screw hole 19 into which the screw 16 is inserted. The screw 16 is fixed to the screw hole 19 of the second pedestal 6 via the screw hole 17 of the first pedestal 5, the screw insertion portion 5 d and the screw hole 18, and the screw hole 12 of the belt table 3. . Accordingly, the belt table 3 and the first pedestal 5 are fixed to the second pedestal 6 by the screws 16.
　図４は、図１においてベルト２の幅方向の中央で切った４－４断面の概略断面図および部分拡大図であり、第１の台座５および第２の台座６については記載を省略している。図１および図４は、ナット４を左回転させてベルトテーブル３のガイド孔１０からベルト２を最大限引き出した状態を示している。図４に示すように、ベルト２の両端部に形成された抜け止め９が、ベルトテーブル３の抜け抑制部２０と接触しており、この状態からベルト２の両端部がさらに上方に移動することが抑制されている。すなわち、ベルト２の抜け止め９とベルトテーブル３の抜け抑制部２０によって、ベルト２がさらに上方に動いてガイド孔１０から抜けてしまうことを抑制している。このため、使用者が保持装置１によって物体（保持対象物）を保持する操作（保持操作）を行う際、ベルト２とベルトテーブル３とで囲まれた空間に保持対象物を配置してベルト２を締め付ければよい。その結果、使用者にとって保持操作が容易となり操作性が向上する。 FIG. 4 is a schematic cross-sectional view and a partially enlarged view of a section 4-4 cut at the center in the width direction of the belt 2 in FIG. 1. The description of the first pedestal 5 and the second pedestal 6 is omitted. Yes. 1 and 4 show a state where the nut 2 is rotated counterclockwise and the belt 2 is pulled out from the guide hole 10 of the belt table 3 to the maximum. As shown in FIG. 4, the stoppers 9 formed at both ends of the belt 2 are in contact with the stoppers 20 of the belt table 3, and the both ends of the belt 2 move further upward from this state. Is suppressed. That is, the stopper 2 of the belt 2 and the stopper 20 of the belt table 3 prevent the belt 2 from moving further upward and coming out of the guide hole 10. For this reason, when the user performs an operation (holding operation) for holding an object (holding object) by the holding device 1, the holding object is arranged in a space surrounded by the belt 2 and the belt table 3 and the belt 2. Can be tightened. As a result, the holding operation is easy for the user and the operability is improved.
　また、ナット４を右回転させるとベルトテーブル３に対してベルト２の両端部が下方に移動する。このとき、ナット４を所定量右回転させ、ナット４の雌ねじ１３の端部１３ａ（図２参照）がベルト２のストッパー８（図２、図３参照）と接触すると、ナット４の右回転を続けることはできなくなる。すなわち、ナット４の雌ねじ１３の端部１３ａとベルト２のストッパー８によって、ベルト２の両端部が所定位置を越えて下方に移動することを抑制している。 Also, when the nut 4 is rotated clockwise, both ends of the belt 2 move downward with respect to the belt table 3. At this time, when the nut 4 is rotated clockwise by a predetermined amount and the end 13a (see FIG. 2) of the female screw 13 of the nut 4 comes into contact with the stopper 8 (see FIGS. 2 and 3) of the belt 2, the nut 4 is rotated clockwise. You can't continue. In other words, the end portion 13a of the female screw 13 of the nut 4 and the stopper 8 of the belt 2 prevent both end portions of the belt 2 from moving downward beyond a predetermined position.
　保持装置１は、ナット４を回転させることでベルト２を上下させている。このとき、ベルト２の両端部のそれぞれ（以下、ベルト２の両端部とする）がベルトテーブル３のガイド孔１０と、ベルトテーブル３のテーブル下部３ｂの一部分（ガイド孔１０の下方に位置する部分）に挿入されることによってベルト２の可動する位置が制限される。これにより、ベルト２の両端部のラックねじ７とナット４の雌ねじ１３とを係合させた状態で、ベルト２を上下させることができる。すなわち、ベルトテーブル３のガイド孔１０と、ベルトテーブル３のテーブル下部３ｂの一部分（ガイド孔１０の下方に位置する部分）は、ベルト２の両端部のラックねじ７とナット４の雌ねじ１３とが係合する位置にベルト２の両端部をガイドする。また、ベルトテーブル３のテーブル上部３ａと第１の台座５は、ナット４が上下方向に可動する位置を制限するとともにナット４を回転可能に保持している。なお、ベルト２はＵ字状で保持されることが好ましいが、例えばＶ字状であってもよい。また、ガイドするものの他の例として、例えばベルトテーブル３の上面に溝を２つ形成してラックねじ７の両端部を挿入させる構成としてもよい。 The holding device 1 moves the belt 2 up and down by rotating the nut 4. At this time, each of both end portions of the belt 2 (hereinafter referred to as both end portions of the belt 2) is a guide hole 10 of the belt table 3 and a part of the table lower portion 3b of the belt table 3 (a portion located below the guide hole 10). ), The movable position of the belt 2 is limited. Thereby, the belt 2 can be moved up and down in a state where the rack screws 7 at both ends of the belt 2 and the female screws 13 of the nut 4 are engaged. That is, the guide hole 10 of the belt table 3 and a part of the table lower part 3 b of the belt table 3 (the part located below the guide hole 10) are formed by the rack screw 7 at both ends of the belt 2 and the female screw 13 of the nut 4. Both ends of the belt 2 are guided to the engaging positions. The table upper portion 3a and the first pedestal 5 of the belt table 3 restrict the position where the nut 4 can move in the vertical direction and hold the nut 4 rotatably. The belt 2 is preferably held in a U shape, but may be in a V shape, for example. As another example of the guide, for example, two grooves may be formed on the upper surface of the belt table 3 and both ends of the rack screw 7 may be inserted.
　図５は、保持装置１を用いて筒状のカメラ２１を保持した状態を示す図である。撮影された映像が傾かないようにするためには、カメラ２１を所定の状態で保持装置１に保持する必要がある。カメラ２１をベルト２で締め付けるとき、カメラ２１が回転しない方が操作しやすく好ましい。ナット４を回すとベルト２の両端部が同時に引き込まれるので、保持対象物をベルト２で締め付ける際に、カメラ２１が回転することなくカメラ２１を締め付けることができる。 FIG. 5 is a view showing a state in which the cylindrical camera 21 is held using the holding device 1. In order to prevent the captured image from tilting, it is necessary to hold the camera 21 in the holding device 1 in a predetermined state. When the camera 21 is fastened with the belt 2, it is preferable that the camera 21 does not rotate because it is easy to operate. When the nut 4 is turned, both ends of the belt 2 are drawn simultaneously, so that the camera 21 can be tightened without rotating the camera 21 when the object to be held is tightened with the belt 2.
　なお、保持対象物として、例えば筒状のカメラ２１を例にしているが、カメラ２１は必ずしも筒状でなくてもよく、例えば三角形や四角形など他の断面形状を有するものも含む。また、保持対象物はカメラでなくてもよく、例えば、ライトやプロジェクターなどでも保持装置１を用いて締め付け固定できる。 In addition, although the cylindrical camera 21 is taken as an example of the holding object, for example, the camera 21 does not necessarily have a cylindrical shape, and includes, for example, those having other cross-sectional shapes such as a triangle and a quadrangle. Further, the object to be held need not be a camera. For example, a light or a projector can be fastened and fixed using the holding device 1.
　また、一般的には、保持装置１の組み立てに際し、ベルト２の両端部をガイド孔１０に挿入し、仮保持した状態では、両端部のラックねじ７が半ピッチずれてしまう。実施の形態１では、ラックねじ７を二条ねじで形成したため、両端部のラックねじ７は同時に係合を開始できるので、組立て作業が容易になっている。 In general, when the holding device 1 is assembled, both ends of the belt 2 are inserted into the guide holes 10 and temporarily held, and the rack screws 7 at both ends are shifted by a half pitch. In the first embodiment, since the rack screw 7 is formed by a double thread, the rack screws 7 at both ends can start to be engaged at the same time, so that the assembling work is facilitated.
　（変形例）
　図６は実施の形態１に係る保持装置の変形例を示す斜視図である。図６に示すように、保持装置１ａでは、ベルトテーブル３の上面（保持対象物側の面）の中央部に係合受け部２２を設けている。係合受け部２２は、ベルトテーブル３の上面から上方に突出しており、上方に付勢されている。すなわち、係合受け部２２は基台部材に設けられた収容可能な係合受け部である。カメラ２１などの保持対象物に係合穴がある場合、保持対象物を保持装置１ａに締め付け固定する際に、係合受け部２２が保持対象物の係合穴に係合する。このため、保持対象物が移動すること、あるいは回転することが抑制され、保持対象物を保持装置１ａに安定的に締め付け固定することができる。なお、変形例では、カメラ２１などの保持対象物に係合部（凹部）を設け、ベルトテーブル３に係合受け部２２（凸部）を設けた構成としたが、逆であってもよい。また、保持対象物に係合穴が無い場合には、係合受け部２２が保持対象物と接することによって下方に移動した状態で、保持対象物が保持装置１ａに締め付け固定される。 (Modification)
6 is a perspective view showing a modification of the holding device according to Embodiment 1. FIG. As shown in FIG. 6, in the holding device 1 a, the engagement receiving portion 22 is provided at the center of the upper surface (the surface on the holding object side) of the belt table 3. The engagement receiving portion 22 protrudes upward from the upper surface of the belt table 3 and is biased upward. That is, the engagement receiving portion 22 is a retractable engagement receiving portion provided on the base member. When the holding object such as the camera 21 has an engagement hole, the engagement receiving portion 22 engages with the engagement hole of the holding object when the holding object is fastened and fixed to the holding device 1a. For this reason, it is suppressed that a holding target object moves or rotates, and a holding target object can be stably clamped and fixed to the holding device 1a. In the modified example, the holding object such as the camera 21 is provided with the engaging portion (concave portion) and the belt table 3 is provided with the engaging receiving portion 22 (convex portion). . In addition, when there is no engagement hole in the holding object, the holding object is clamped and fixed to the holding device 1a in a state where the engagement receiving portion 22 is moved downward by contacting the holding object.
