Description

本発明は、プロジェクタ等の傾斜角を容易に調節できる傾斜角調節台および傾斜角調節台付きプロジェクターワゴンに関するものであり、特に傾斜角を２段階に調節できる傾斜角調節台および傾斜角調節台付きプロジェクタワゴンに関するものである。   The present invention relates to a tilt angle adjusting table and a projector wagon with a tilt angle adjusting table that can easily adjust the tilt angle of a projector or the like, and in particular, with a tilt angle adjusting table and a tilt angle adjusting table that can adjust the tilt angle in two stages. It relates to a projector wagon.

プロジェクタは使用時において、映像を投影するスクリーンまでの距離の関係、プロジェクタとスクリーンとの高さの関係等により、傾斜角を調節する必要がある。
従来よりプロジェクタの傾斜角の調節は、プロジェクタの下端部の隅部に設けたねじを出し入れして行うようにされているのが通常であるが、特開平８−２２７１０４号公報記載のプロジェクタ用傾斜角調節装置や特開平２００６−２３５１５６号公報記載のプロジェクタの設置スタンドにおいても、プロジェクタの傾斜角の調節手段が開示されたいる。
ところがこれらの傾斜角調節手段はいずれも、充分とはいえない。 When the projector is used, it is necessary to adjust the tilt angle depending on the relationship between the distance to the screen on which the image is projected and the relationship between the height of the projector and the screen.
Conventionally, the inclination angle of the projector is usually adjusted by inserting and removing a screw provided at the corner of the lower end portion of the projector. However, the inclination for the projector described in Japanese Patent Application Laid-Open No. 8-227104 is known. Also in the angle adjusting device and the projector installation stand described in Japanese Patent Application Laid-Open No. 2006-235156, means for adjusting the tilt angle of the projector is disclosed.
However, none of these tilt angle adjusting means is sufficient.

第１の通常の手段はプロジェクタ底部の隅に設けた雌ネジ部に雄ねじ部材を螺合し、この雄ねじ部材に形成されたつまみ部を手で廻して雄ねじ部材を出し入れして行うものであるから、その出入れ量に一定の制約があり、傾斜角調節範囲も充分とはいえない。そこで、下に本やノートを敷き重ねたり、他の物品を下に敷いたりすることが行われているが、使用時にこれらを用意することは非常に煩わしい。また、ねじ部材１回転当たりねじ１ピッチ分しか傾斜角が変化しないので、微調整の場合は都合がよいが、傾斜角を大きく変える場合には手間が掛かる。   The first normal means is to perform by inserting a male screw member into a female screw portion provided at the corner of the bottom of the projector and turning the knob formed on the male screw member by hand to insert and remove the male screw member. However, there are certain restrictions on the amount of movement, and the tilt angle adjustment range is not sufficient. Thus, books and notebooks are laid down underneath, and other articles are laid down underneath, but it is very troublesome to prepare them during use. Further, since the inclination angle changes only by one pitch per screw member rotation, it is convenient for fine adjustment, but it takes time to change the inclination angle greatly.

第２の手段（特開平８−２２７１０４号公報記載）は、プロジェクタの下端部コーナに同公報の図２に示すように、きのこ状の部材を傘の部分を下にして配置し軸状部分３３の上端部に複数のリング状溝３３aを設け、かつきのこ状の部材をばねにより下向きに付勢し、一方先端部が前記リンク状溝に係合し得る調節部材４０を、前記軸状部分に直角方向に摺動可能、かつリング状溝に係合する方向にばねで付勢され、リング状溝との係合位置を変えることにより、きの状の部材の出入りを加減してこ傾斜角を調節するようにされている。しかし、構造が複雑であり、また傾斜角調節台等の別部材を使用するものではないので、構造改変等の追加工事をしない限り他の機種のプロジェクタには適用できないという問題点がある。   As a second means (described in Japanese Patent Laid-Open No. 8-227104), as shown in FIG. 2 of the same publication, a mushroom-like member is arranged with an umbrella portion facing down at the lower end corner of the projector. A plurality of ring-shaped grooves 33a are provided at the upper end of the shaft, and an adjustment member 40 whose front end is engaged with the link-shaped groove while biasing the mushroom-shaped member downward by a spring is provided in the shaft-shaped portion. It is slidable in a right angle direction and is urged by a spring in a direction to engage with the ring-shaped groove, and by changing the engagement position with the ring-shaped groove, the entrance and exit of the mushroom-shaped member is adjusted to reduce the inclination angle. It is designed to adjust. However, since the structure is complicated and no separate member such as an inclination angle adjusting table is used, there is a problem that it cannot be applied to other types of projectors unless additional work such as structural modification is performed.

第３の手段（特開平２００６−２３５１５６号公報記載）は、同公報段落「００３０」によれば、プロジェクタ設置台としての天板２は一端が蝶番により連結され、傾斜可能とされると共にチルトつまみ７を回転させると、チルトつまみ７に連動するピニオンが回転し、ピニオンの回転運動を天板２と接続するラック（いずれも図示せず）で直線運動に変換することにより、天板２に傾きを持たせる。これによりプロジェクタの傾斜角を調節するようにされている。しかし、構造が複雑でコストが高くなるという問題点がある。
特開平８−２２７１０４号公報 特開平２００６−２３５１５６号公報 According to the third means (described in Japanese Patent Application Laid-Open No. 2006-235156), according to paragraph “0030” of the same publication, the top plate 2 as a projector installation base is connected at one end with a hinge so that it can be tilted and a tilt knob. When 7 is rotated, the pinion interlocked with the tilt knob 7 is rotated, and the rotational movement of the pinion is tilted to the top plate 2 by converting it into a linear motion with a rack (not shown) connected to the top plate 2. To have. Thereby, the inclination angle of the projector is adjusted. However, there is a problem that the structure is complicated and the cost is high.
JP-A-8-227104 JP 2006-235156 A

解決しようとする課題は、以下の通りである。
第１の手段では傾斜角調節範囲が小さいのでプロジェクタの下に敷く本やノートや他の物品を用意しなければならず、また傾斜角の微調整はできるが、大きく変える場合には不便である。第２の手段では、構造が複雑であり、また他の機種を使用する際には構造を改変する追加工事をしないと適用できない。第３の手段では、傾斜角調節用のピニオンやラック使用するので構造が複雑である。 The problems to be solved are as follows.
In the first means, since the tilt angle adjustment range is small, it is necessary to prepare a book, notebook or other article under the projector, and the tilt angle can be finely adjusted, but it is inconvenient when changing greatly. The second means has a complicated structure, and cannot be applied unless an additional work for modifying the structure is performed when using another model. The third means uses a pinion or a rack for adjusting the inclination angle, so that the structure is complicated.

以下本発明の実施の形態を図面に基づいて詳細に説明する。
図１において、１０は載置部材であり、矩形状の板状部材で構成され、その前端部は上方に折り曲げられて立上げ縁部１２が形成され、載置部材自体の強度向上と載置したプロジェクタの脱落防止を図っている。載置部材１０の前端寄りの下面には傾斜角調節部材１４が揺動可能に取り付けられている。傾斜角調節部材１４は所定高さの立面部１６とその下端部から略直角方向に延出した底面部１８を有する断面がＬ字状の部材であり、立面部１６の上端部は載置部材１０の前端部から所定距離Ａだけ離れた位置に蝶番２０により揺動可能に取り付けられている。このようにして、載置部材１０と傾斜角調節部材１４とにより傾斜角調節台２２が構成される。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
In FIG. 1, reference numeral 10 denotes a mounting member, which is formed of a rectangular plate-like member, and its front end portion is bent upward to form a rising edge portion 12 to improve the strength of the mounting member itself and to mount it. This prevents the projector from falling off. An inclination angle adjusting member 14 is swingably attached to the lower surface near the front end of the mounting member 10. The inclination angle adjusting member 14 is a member having an L-shaped cross section having a rising surface portion 16 having a predetermined height and a bottom surface portion 18 extending substantially perpendicularly from the lower end portion thereof, and the upper end portion of the rising surface portion 16 is mounted. A hinge 20 is attached at a position separated from the front end of the mounting member 10 by a predetermined distance A so as to be swingable. In this manner, the mounting member 10 and the tilt angle adjusting member 14 constitute the tilt angle adjusting table 22.

さらに、載置部材１０の後端部には蝶番２４が取り付けられ、この蝶番２４を介して傾斜角調節台２２は、プロジェクタを設置すべき設置台上の所定位置に揺動可能に取り付けられる。すなわち、図１（ロ）に示すように載置部材１０の前端部から立面部１６までの距離Ａは立面部１６の高さ寸法Ｂと同じかあるいは若干長くなるように決定される。   Further, a hinge 24 is attached to the rear end portion of the mounting member 10, and the inclination angle adjusting base 22 is attached to the projector at a predetermined position on the installation base where the projector is to be installed via the hinge 24. That is, as shown in FIG. 1B, the distance A from the front end portion of the mounting member 10 to the elevation surface portion 16 is determined to be the same as or slightly longer than the height dimension B of the elevation surface portion 16.

図２（イ）に示すように、立面部１６を立てると載置部材１０は設置台２６に対してθ１なる傾斜角をなすが、図２（ロ）に示すように立面部１６を載置部材１０の後端部寄りに倒すと、傾斜角調節部材１４は底面部１８の先端部が載置部材１０に接するまで倒れ傾斜角θ２となり、傾斜角が小さくなる。図２（ハ）に示すように、傾斜角調節部材１４を逆方向に倒すと立面部１６の一面側は載置部材１０の下面に接すると共に立面部１６の他面側は設置台２６の端面に接するようになり、載置部材１０は水平になり、傾斜角はゼロとなる。従って、傾斜角を大きく２段に調節することができる。   As shown in FIG. 2 (a), when the upright portion 16 is erected, the mounting member 10 has an inclination angle θ1 with respect to the installation table 26. However, as shown in FIG. When tilted closer to the rear end of the mounting member 10, the tilt angle adjusting member 14 is tilted until the tip of the bottom surface portion 18 comes into contact with the mounting member 10, so that the tilt angle θ <b> 2 is reduced. As shown in FIG. 2C, when the inclination angle adjusting member 14 is tilted in the reverse direction, one surface side of the elevation surface portion 16 contacts the lower surface of the mounting member 10 and the other surface side of the elevation surface portion 16 is the installation base 26. The mounting member 10 becomes horizontal, and the inclination angle becomes zero. Accordingly, the tilt angle can be adjusted to a large two-stage.

このように、傾斜角調節部材１４を立てたり、前後に起伏させることにより載置部材１０の傾斜角を容易に調節し、載置部材１０上に載置したプロジェクタの傾斜角を簡単に調節することができる。なお、通常プロジェクタは殆ど例外なくその底部の隅に、前述した傾斜角調節用のねじを設けているので、傾斜角を微調節するには、このねじを使用すればよい。従って、本発明の傾斜角調節台を使用すれば、傾斜角を大きく調節することも、微調節することも、極めて簡単かつ、容易である。   Thus, the inclination angle of the projector placed on the mounting member 10 can be easily adjusted by easily adjusting the inclination angle of the mounting member 10 by raising or lowering the inclination angle adjusting member 14 back and forth. be able to. Normally, projectors are provided with the above-described tilt angle adjusting screws at the bottom corners with almost no exception, and these screws may be used to finely adjust the tilt angle. Therefore, if the tilt angle adjusting table of the present invention is used, it is very simple and easy to adjust the tilt angle greatly and finely adjust it.

図３において、３０はプロジェクタワゴンであり、プロジェクタの設置台としての天板３２には、その前端寄りに図１に示す傾斜角調節台２２が配置され、かつその構成部品である載置部材１０は後端部側が蝶番２４により揺動可能に取付られている。その取付位置は図２（ハ）に示すように、傾斜角調節部材１４を前方に倒し、立面部１６が載置部材１０の裏面に接するようにしたとき、底面部１８は設置台としての天板３２の前端面に当接するか、あるいは前端面との間に若干の隙間を生ずる状態となるように決定する。そして、傾斜角調節台２２上には図３に示すようにプロジェクタ３１が載置される。   In FIG. 3, reference numeral 30 denotes a projector wagon. A top plate 32 as a projector installation base is provided with a tilt angle adjustment base 22 shown in FIG. 1 near the front end thereof, and a mounting member 10 which is a component thereof. The rear end side is swingably attached by a hinge 24. As shown in FIG. 2 (c), when the tilt angle adjusting member 14 is tilted forward and the upright surface portion 16 is in contact with the back surface of the mounting member 10, the bottom surface portion 18 serves as an installation base. It determines so that it may contact | abut to the front-end surface of the top plate 32, or it may be in the state which produces a some clearance gap between front-end surfaces. Then, the projector 31 is placed on the tilt angle adjusting table 22 as shown in FIG.

このような構成とすることにより、前述の如く傾斜角調節部材１４を立てたり前後に倒すことにより、プロジェクタ３１の傾斜角を簡単に大きく調節することができ、また通常のプロジェクタ３１の底部に設けられた傾斜角調節ねじを廻すことにより傾斜角の微調節が容易にできるという効果を奏する。   With such a configuration, as described above, the tilt angle adjusting member 14 can be easily and largely adjusted by raising or tilting the tilt angle adjusting member 14 forward and backward, and provided at the bottom of the normal projector 31. There is an effect that the tilt angle can be finely adjusted easily by turning the tilt angle adjusting screw.
