Description

本発明は、二つの部材(対象物)を回動可能に連結するヒンジに関する。   The present invention relates to a hinge that rotatably connects two members (objects).

従来、複写機、ファクシミリ、スキャナー等、オフィスで使用される事務機器の本体と、原稿を事務機器の本体上部の読み取り部に圧着するための原稿圧着板と、を回動可能に連結するヒンジが知られている。例えば、特許文献1に記載の如くである。
特許文献1に記載のヒンジは巻きバネの付勢力によって原稿圧着板の重量を支え、フリーストップ機能(任意の回動角度で原稿圧着板を保持する機能)を達成する。
特許文献1に記載のヒンジは巻きバネの他、事務機器の本体に固定される取付部材、原稿圧着板に固定されるリフト部材に第2ヒンジピンを介して回動可能に連結されるとともに第1ヒンジピンを介して取付部材に回動可能に連結される支持部材、および支持部材に相対移動(摺動)可能に支持されるとともに巻きバネに押されて取付部材に固定された受圧ピンに当接するカムスライダを備える。
Conventionally, there is a hinge that rotatably connects a main body of office equipment used in an office such as a copying machine, a facsimile machine, a scanner, and the like, and a manuscript crimping plate for crimping a manuscript to a reading unit at the top of the main body of the office equipment. Are known. For example, as described in Patent Document 1.
The hinge described in Patent Document 1 supports the weight of the original pressing plate by the urging force of the winding spring, and achieves a free stop function (function to hold the original pressing plate at an arbitrary rotation angle).
The hinge described in Patent Document 1 is connected to a mounting member fixed to the main body of the office equipment and a lift member fixed to the original pressure plate in addition to a winding spring, via a second hinge pin, so as to be rotatable. A support member that is rotatably connected to the mounting member via a hinge pin, and is supported by the support member so as to be relatively movable (slidable), and is pressed by a winding spring to contact a pressure receiving pin fixed to the mounting member. A cam slider is provided.

特許文献1に記載のヒンジのように、巻きバネの付勢力を用いてフリーストップ機能を達成するヒンジ(以下、「従来型ヒンジ」と表記する。)は以下の問題点を有する。
第一に、従来型ヒンジは部品点数が多い。特許文献1に記載のヒンジの場合、フリーストップ機能を達成する最小限の構成としては巻きバネ、取付部材、第1ヒンジピン、支持部材、受圧ピンおよびカムスライダの六つの部品を要する。部品点数が多くなることにより、組み立て工数および製造コストの増大等を招来する。
第二に、従来型ヒンジを構成する部材群には常に巻きバネの付勢力が作用するため、巻きバネの付勢力が大きい場合には当該部材群を構成する材料には非常に高い強度が求められる。従って、当該部材群を構成する材料としては金属材料、あるいはクリープ変形に対する耐性が高い高強度の樹脂材料(例えば、エンジニアリングプラスチック等)を使用する必要が生じる。また、高強度の樹脂材料を用いる場合であっても、強度を確保するためには部材の形状を肉厚にする必要がある。結果として、一般的な樹脂材料を使用する場合に比べて材料コストが高くなる。
第三に、従来型ヒンジの場合、巻きバネの付勢力(弾性力)を大きくするためには巻きバネの外形寸法を大きくする必要が生じる。巻きバネの外形寸法が大きくなることにより、従来型ヒンジの外形寸法も全体として大型化し、ヒンジの小型化が困難となる。
Like the hinge described in Patent Document 1, a hinge that achieves a free stop function using the urging force of a winding spring (hereinafter referred to as “conventional hinge”) has the following problems.
First, the conventional hinge has a large number of parts. In the case of the hinge described in Patent Document 1, the minimum configuration for achieving the free stop function requires six parts: a winding spring, a mounting member, a first hinge pin, a support member, a pressure receiving pin, and a cam slider. An increase in the number of parts causes an increase in assembly man-hours and manufacturing costs.
Second, since the biasing force of the winding spring always acts on the member group constituting the conventional hinge, when the biasing force of the winding spring is large, the material constituting the member group is required to have a very high strength. It is done. Therefore, it is necessary to use a metal material or a high-strength resin material (for example, engineering plastic) having high resistance to creep deformation as a material constituting the member group. Even when a high-strength resin material is used, it is necessary to increase the thickness of the member in order to ensure the strength. As a result, the material cost is higher than when a general resin material is used.
Third, in the case of a conventional hinge, it is necessary to increase the outer dimensions of the winding spring in order to increase the urging force (elastic force) of the winding spring. As the outer dimension of the winding spring increases, the outer dimension of the conventional hinge increases as a whole, making it difficult to reduce the size of the hinge.

The trunk portion of the rotation shaft member 130L is connected to the right side of the head. A male screw is formed on the outer peripheral surface of the body portion of the rotating shaft member 130L. Since the shape of the rotation shaft member 130R of this embodiment is symmetrical with respect to the rotation shaft member 130L, detailed description thereof is omitted.

図2、図4および図5に示す如く、第一固定部材110の上半部が第二固定部材120の開口部123に差し込まれ、側面視で第一固定部材110の軸穴111L・111Rおよび第二固定部材120の軸孔124L・軸孔124Rが重ねられる。
また、回動軸部材130Lは軸孔124Lに貫装され、軸穴111Lに螺装され、第一固定部材110に固定される。同様に、回動軸部材130Rは軸孔124Rに貫装され、軸穴111Rに螺装され、第一固定部材110に固定される。
回動軸部材130L・130Rが第一固定部材110に固定されたとき、回動軸部材130Lの軸線(回動軸部材130Lの中心を通る左右方向に平行な直線)および回動軸部材130Rの軸線は一直線となり、回動軸部材130L・130Rは実質的には第一固定部材110に固定された一本の軸としての機能を果たす。
回動軸部材130L・130Rが第一固定部材110に固定されたとき、回動軸部材130L・130Rの頭部はそれぞれ軸孔124L・124Rの内部に収容される。また、回動軸部材130L・130Rの頭部の直径は軸孔124L・124Rの直径よりもわずかに小さい。従って、第二固定部材120は、回動軸部材130L・130Rの頭部の外周面と軸孔124L・124Rの内周面とが当接した状態を保持しつつ、回動軸部材130L・130Rひいては第一固定部材110に対して相対回転可能である。
このように、回動軸部材130L・130Rにより、第二固定部材120は第一固定部材110に回動可能に支持される。
As shown in FIGS. 2, 4, and 5, the upper half of the first fixing member 110 is inserted into the opening 123 of the second fixing member 120, and the shaft holes 111 </ b> L and 111 </ b> R of the first fixing member 110 are viewed from the side. The shaft hole 124L and the shaft hole 124R of the second fixing member 120 are overlapped.
The rotating shaft member 130L is inserted into the shaft hole 124L, screwed into the shaft hole 111L, and fixed to the first fixing member 110. Similarly, the rotation shaft member 130R is inserted into the shaft hole 124R, screwed into the shaft hole 111R, and fixed to the first fixing member 110.
When the rotation shaft members 130L and 130R are fixed to the first fixing member 110, the axis of the rotation shaft member 130L (a straight line passing through the center of the rotation shaft member 130L and parallel to the left-right direction) and the rotation shaft member 130R. The axis is a straight line, and the rotation shaft members 130L and 130R substantially function as a single shaft fixed to the first fixing member 110.
When the rotating shaft members 130L and 130R are fixed to the first fixing member 110, the heads of the rotating shaft members 130L and 130R are accommodated in the shaft holes 124L and 124R, respectively. Moreover, the diameter of the head of the rotating shaft members 130L and 130R is slightly smaller than the diameter of the shaft holes 124L and 124R. Accordingly, the second fixing member 120 maintains the state in which the outer peripheral surface of the head of the rotary shaft members 130L and 130R and the inner peripheral surface of the shaft holes 124L and 124R are in contact with each other, and the rotary shaft members 130L and 130R. As a result, it can rotate relative to the first fixing member 110.
In this manner, the second fixing member 120 is rotatably supported by the first fixing member 110 by the rotation shaft members 130L and 130R.

図4に示す如く、回動軸部材130L・130Rによって第二固定部材120が第一固定部材110に回動可能に支持されたとき、第二固定部材120に形成された嵌合溝125L(嵌合溝125R)は回動軸部材130L・130Rの軸線に平行な方向(左右方向)から見て当該軸線を中心とする円弧状となる。   As shown in FIG. 4, when the second fixing member 120 is rotatably supported by the first fixing member 110 by the rotating shaft members 130 </ b> L and 130 </ b> R, a fitting groove 125 </ b> L (fitting) is formed in the second fixing member 120. The joint groove 125R) has an arc shape centered on the axis when viewed from a direction parallel to the axis of the rotation shaft members 130L and 130R (left and right direction).

以下では便宜上、事務機器本体2に対する原稿圧着板3の回動角度をθ、ヒンジ100の回動角度(第一固定部材110に対する第二固定部材120の回動角度)をφと定義する。図1において実線で示す如く、事務機器本体2に対して原稿圧着板3が閉じているとき、θ=φ=0°である。また、事務機器本体2に対して原稿圧着板3が開いていく(図1において原稿圧着板3が時計回りに回動する)とき、θおよびφは大きくなる。本実施形態では、事務機器本体2に対して原稿圧着板3が最も大きく開いたとき、θ=φ=90°である(図1中の二点鎖線参照)。   Hereinafter, for the sake of convenience, the rotation angle of the original cover 3 with respect to the office equipment body 2 is defined as θ, and the rotation angle of the hinge 100 (the rotation angle of the second fixing member 120 with respect to the first fixing member 110) is defined as φ. As shown by a solid line in FIG. 1, θ = φ = 0 ° when the original cover 3 is closed with respect to the office equipment body 2. Further, when the original cover 3 is opened with respect to the office equipment body 2 (the original cover 3 is rotated clockwise in FIG. 1), θ and φ are increased. In the present embodiment, θ = φ = 90 ° when the original cover 3 is opened most with respect to the office equipment body 2 (see the two-dot chain line in FIG. 1).

ピン部材141L・141Rは本発明に係るピン部材の実施の一形態である。
図7に示す如く、ピン部材141L・141Rはその軸線方向が左右方向に平行となる概ね円筒形状の部材である。本実施形態のピン部材141L・141Rはいわゆるスプリングピンであり、バネ鋼あるいはステンレス鋼からなる金属板に曲げ加工を施すことにより製造される。ピン部材141L・141Rの上部にはピン部材141L・141Rの左端部から右端部にわたって外周面から内周面に貫通する切れ目(隙間)が形成されており、ピン部材141L・141Rの半径方向(ピン部材141L・141Rの軸線方向に垂直な方向)に弾性変形可能である。
The pin members 141L and 141R are an embodiment of the pin member according to the present invention.
As shown in FIG. 7, the pin members 141L and 141R are substantially cylindrical members whose axial direction is parallel to the left-right direction. The pin members 141L and 141R of the present embodiment are so-called spring pins, and are manufactured by bending a metal plate made of spring steel or stainless steel. On the upper part of the pin members 141L and 141R, a cut (gap) penetrating from the outer peripheral surface to the inner peripheral surface is formed from the left end portion to the right end portion of the pin members 141L and 141R. It can be elastically deformed in a direction perpendicular to the axial direction of the members 141L and 141R.

図2、図4および図5に示す如く、ピン部材141Lの右半部は第一固定部材110のピン穴112Lに差し込まれる。本実施形態ではピン穴112Lの直径は外力が作用していないときのピン部材141Lの直径(外径)よりもわずかに小さいので、ピン穴112Lに差し込まれたピン部材141Lの右半部はピン部材141Lの半径方向においてピン部材141Lの直径(外径)が小さくなる方向に弾性変形する。従って、ピン部材141Lの右半部の外周面はピン穴112Lの内周面に強く当接し、ピン部材141Lは第一固定部材110に脱落不能に固定される。
同様に、ピン部材141Rの左半部は第一固定部材110のピン穴112Rに差し込まれ、ピン部材141Rは第一固定部材110に脱落不能に固定される。
図4に示す如く、ピン部材141L・141Rが第一固定部材110に固定されたとき、回動軸部材130L・130Rの軸線およびピン部材141L・141Rの軸線は互いに平行となる(本実施例では、回動軸部材130L・130Rの軸線およびピン部材141L・141Rの軸線はいずれも左右方向に平行となる)。
図2に示す如く、第一固定部材110に固定されたピン部材141Lの左半部は第二固定部材120の嵌合溝125Lに嵌合する。同様に、図3に示す如く、第一固定部材110に固定されたピン部材141Rの右半部は第二固定部材120の嵌合溝125Rに嵌合する。
As shown in FIGS. 2, 4 and 5, the right half of the pin member 141 </ b> L is inserted into the pin hole 112 </ b> L of the first fixing member 110. In the present embodiment, since the diameter of the pin hole 112L is slightly smaller than the diameter (outer diameter) of the pin member 141L when no external force is acting, the right half of the pin member 141L inserted into the pin hole 112L is a pin. The pin member 141L is elastically deformed in a direction in which the diameter (outer diameter) of the pin member 141L decreases in the radial direction of the member 141L. Accordingly, the outer peripheral surface of the right half portion of the pin member 141L is in strong contact with the inner peripheral surface of the pin hole 112L, and the pin member 141L is fixed to the first fixing member 110 so as not to fall off.
Similarly, the left half of the pin member 141R is inserted into the pin hole 112R of the first fixing member 110, and the pin member 141R is fixed to the first fixing member 110 so as not to drop off.
As shown in FIG. 4, when the pin members 141L and 141R are fixed to the first fixing member 110, the axes of the rotating shaft members 130L and 130R and the axes of the pin members 141L and 141R are parallel to each other (in this embodiment). The axis of the rotating shaft members 130L and 130R and the axis of the pin members 141L and 141R are both parallel to the left and right direction).
As shown in FIG. 2, the left half of the pin member 141 </ b> L fixed to the first fixing member 110 is fitted in the fitting groove 125 </ b> L of the second fixing member 120. Similarly, as shown in FIG. 3, the right half of the pin member 141 </ b> R fixed to the first fixing member 110 is fitted into the fitting groove 125 </ b> R of the second fixing member 120.

以下では図4、図8および図9を用いてヒンジ100の回動角度φと嵌合溝125L・125Rの幅W(φ)およびピン部材141L・141Rの直径R(φ)との関係について説明する。   Hereinafter, the relationship between the rotation angle φ of the hinge 100, the width W (φ) of the fitting grooves 125L and 125R, and the diameter R (φ) of the pin members 141L and 141R will be described with reference to FIGS. To do.

図4に示す如く、嵌合溝125L・125Rの幅W(φ)は、ヒンジ100の回動角度がφのときの「嵌合溝125L・125Rを回動軸部材130L・130Rの軸線およびピン部材141L・141Rの軸線を通る平面5」と「嵌合溝125L・125Rの二つの内周面」と、の交線間の距離を指す。換言すれば、嵌合溝125L・125Rの幅W(φ)は、ヒンジ100の回動角度がφのときにおける嵌合溝125L・125Rの内周面のうち、ピン部材141L・141Rの外周面に対向する二つの部分(回動軸部材130L・130Rの軸線から近い部分および遠い部分)の間の距離を指す。
また、ピン部材141L・141Rの直径R(φ)は、厳密には「ヒンジ100の回動角度がφのときのピン部材141L・141Rのうち嵌合溝125L・125Rに嵌合している部分の直径」を指す。
As shown in FIG. 4, the width W (φ) of the fitting grooves 125L and 125R is “the fitting grooves 125L and 125R are connected to the axis and pins of the turning shaft members 130L and 130R when the rotation angle of the hinge 100 is φ. The distance between the intersecting lines of “the plane 5 passing through the axis of the members 141L and 141R” and “the two inner peripheral surfaces of the fitting grooves 125L and 125R” is indicated. In other words, the width W (φ) of the fitting grooves 125L and 125R is the outer circumferential surface of the pin members 141L and 141R among the inner circumferential surfaces of the fitting grooves 125L and 125R when the rotation angle of the hinge 100 is φ. Is a distance between two portions (portions near and far from the axis of the rotation shaft members 130L and 130R).
Strictly speaking, the diameter R (φ) of the pin members 141L and 141R is “the portion of the pin members 141L and 141R when the rotation angle of the hinge 100 is φ is fitted in the fitting grooves 125L and 125R. Of diameter ".

図9中の太い実線は、第二固定部材120が弾性変形しないと仮定した場合の嵌合溝125L・125Rの幅W(φ)を示す。図9中の太い実線で示す如く、本実施形態では嵌合溝125L・125Rの幅W(φ)はヒンジ100の回動角度φが0°以上13°未満のときにはW1で一定であり、ヒンジ100の回動角度φが13°以上21°未満のときにはヒンジ100の回動角度φの増大に伴ってW1からW2まで減少し(W1>W2)、ヒンジ100の回動角度φが21°以上90°以下のときにはW2で一定である。   The thick solid line in FIG. 9 indicates the width W (φ) of the fitting grooves 125L and 125R when it is assumed that the second fixing member 120 is not elastically deformed. As shown by the thick solid line in FIG. 9, in this embodiment, the width W (φ) of the fitting grooves 125L and 125R is constant at W1 when the rotation angle φ of the hinge 100 is 0 ° or more and less than 13 °. When the rotation angle φ of 100 is 13 ° or more and less than 21 °, the rotation angle φ of the hinge 100 decreases from W1 to W2 as the rotation angle φ of the hinge 100 increases (W1> W2). When it is 90 ° or less, W2 is constant.

図9中の太い点線は、ピン部材141L・141Rが弾性変形しないと仮定した場合のピン部材141L・141Rの直径R(φ)を示す。図9中の太い点線で示す如く、ピン部材141L・141Rの直径R(φ)は、W2よりも大きくかつW1よりも小さい値であるR1で一定である(W2<R1<W1)。   Thick dotted lines in FIG. 9 indicate the diameters R (φ) of the pin members 141L and 141R when it is assumed that the pin members 141L and 141R are not elastically deformed. As shown by the thick dotted lines in FIG. 9, the diameters R (φ) of the pin members 141L and 141R are constant at R1 that is larger than W2 and smaller than W1 (W2 <R1 <W1).

図4および図9に示す如く、ヒンジ100の回動角度φが0°以上17°未満であるときにはW(φ)<R(φ)となり、ピン部材141L・141Rの外周面は嵌合溝125L・125Rの内周面に当接しない(あるいは、当接していたとしても軽く触れる程度である)ため、ピン部材141L・141Rの外周面と嵌合溝125L・125Rの内周面との間に摩擦力が(ほとんど)発生しない。   As shown in FIGS. 4 and 9, when the rotation angle φ of the hinge 100 is not less than 0 ° and less than 17 °, W (φ) <R (φ), and the outer peripheral surfaces of the pin members 141L and 141R are the fitting grooves 125L.・ Because it does not come into contact with the inner peripheral surface of 125R (or touches lightly even if it is in contact), it is between the outer peripheral surface of the pin members 141L and 141R and the inner peripheral surface of the fitting grooves 125L and 125R. There is (almost) no frictional force.

図8の(a)および図9に示す如く、ヒンジ100の回動角度φが17°であるときにはW(φ)=R(φ)(=R1)となり、ピン部材141L・141Rの外周面はそれぞれ嵌合溝125L・125Rの内周面の二箇所(嵌合溝125L・125Rの内周面のうち、回動軸部材130L・130Rの軸線に近い部分および遠い部分)に当接する。   As shown in FIGS. 8A and 9, when the rotation angle φ of the hinge 100 is 17 °, W (φ) = R (φ) (= R1), and the outer peripheral surfaces of the pin members 141L and 141R are Respectively contact with two locations on the inner peripheral surfaces of the fitting grooves 125L and 125R (the portions of the inner peripheral surfaces of the fitting grooves 125L and 125R that are close to and far from the axis of the rotary shaft members 130L and 130R).

図8の(b)および図9に示す如く、ヒンジ100の回動角度φが17°よりも大きくかつ90°以下であるときにはW(φ)>R(φ)となり、ピン部材141L・141Rの外周面はそれぞれ嵌合溝125L・125Rの内周面の二箇所に当接する。このとき、ピン部材141L・141Rにおいて嵌合溝125L・125Rに嵌合する部分はピン部材141L・141Rの半径方向(より厳密には、ピン部材141L・141Rの直径が小さくなる方向)に弾性変形し、第二固定部材120の嵌合溝125L・125Rの内周面においてピン部材141L・141Rの外周面に当接する部分の周辺が弾性変形する。
その結果、ピン部材141L・141R(の外周面)と嵌合溝125L・125R(の内周面)とが強く当接し、かつピン部材141L・141Rおよび嵌合溝125L・125Rにおいて当接する部分の面積が大きくなるので、ピン部材141L・141Rおよび嵌合溝125L・125Rの内周面の当接部分に摩擦力が発生し、当該摩擦力が第一固定部材110に対する第二固定部材120の回動に抗するトルクとなる。
As shown in FIGS. 8B and 9, when the rotation angle φ of the hinge 100 is larger than 17 ° and not larger than 90 °, W (φ)> R (φ), and the pin members 141L and 141R The outer peripheral surfaces are in contact with two locations on the inner peripheral surfaces of the fitting grooves 125L and 125R, respectively. At this time, the portions of the pin members 141L and 141R that are fitted into the fitting grooves 125L and 125R are elastically deformed in the radial direction of the pin members 141L and 141R (more precisely, the diameter of the pin members 141L and 141R is reduced). And the periphery of the part contact | abutted to the outer peripheral surface of pin member 141L * 141R in the inner peripheral surface of fitting groove | channel 125L * 125R of the 2nd fixing member 120 deform | transforms elastically.
As a result, the pin members 141L and 141R (outer circumferential surfaces thereof) and the fitting grooves 125L and 125R (inner circumferential surfaces thereof) are in strong contact with each other, and the portions of the pin members 141L and 141R and the fitting grooves 125L and 125R are in contact with each other. Since the area increases, a frictional force is generated at the contact portions of the inner peripheral surfaces of the pin members 141L and 141R and the fitting grooves 125L and 125R, and the frictional force is rotated by the second fixing member 120 relative to the first fixing member 110. Torque against movement.

上記の如く、ヒンジ100の回動角度φが17°よりも大きくかつ90°以下であるとき、現実にはピン部材141L・141Rおよび第二固定部材120の嵌合溝125L・125Rの内周面においてピン部材141L・141Rの外周面に当接する部分の周辺は弾性変形する。従って、図9中において太い二点鎖線で示す如く、W(φ)およびR(φ)はヒンジ100の回動角度φが17°よりも大きくなるにつれて徐々に小さくなり、ヒンジ100の回動角度φが21°以上のときにはW2よりも大きくかつR1よりも小さい値であるW3となる(φ≧21°;W(φ)=R(φ)=W3,W2<W3<R1)。   As described above, when the rotation angle φ of the hinge 100 is larger than 17 ° and not larger than 90 °, the inner peripheral surfaces of the fitting grooves 125L and 125R of the pin members 141L and 141R and the second fixing member 120 are actually. In this case, the periphery of the portion in contact with the outer peripheral surface of the pin members 141L and 141R is elastically deformed. Therefore, as shown by the thick two-dot chain line in FIG. 9, W (φ) and R (φ) gradually decrease as the rotation angle φ of the hinge 100 becomes larger than 17 °, and the rotation angle of the hinge 100 When φ is 21 ° or more, W3 is larger than W2 and smaller than R1 (φ ≧ 21 °; W (φ) = R (φ) = W3, W2 <W3 <R1).

ヒンジ100は原稿圧着板3が比較的大きく開いているとき(θ=φ>17°のとき)にはトルクを発生させる。従って、原稿圧着板3が比較的大きく開いているときに作業者が原稿圧着板3から手を離しても事務機器本体2に対する原稿圧着板3の回動角度θは一定に保持される(フリーストップ機能が達成される)。
ヒンジ100は原稿圧着板3が事務機器本体2に対してほとんど閉じているとき(θ=φ≦17°のとき)にはトルクを発生させない。従って、原稿圧着板3が事務機器本体2に対してほとんど閉じた状態で作業者が原稿圧着板3から手を離した場合、原稿圧着板3は自重により事務機器本体2に向かって落下し、確実に閉じる(θおよびφが減少してゼロになる)。
The hinge 100 generates a torque when the original cover 3 is relatively wide open (when θ = φ> 17 °). Therefore, even if the operator releases his / her hand from the original pressure plate 3 when the original pressure plate 3 is relatively wide open, the rotation angle θ of the original pressure plate 3 relative to the office equipment body 2 is kept constant (fleece). Top function is achieved).
The hinge 100 does not generate torque when the original cover 3 is almost closed with respect to the office equipment body 2 (when θ = φ ≦ 17 °). Therefore, when the operator releases his / her hand from the document crimping plate 3 with the document crimping plate 3 almost closed with respect to the office device body 2, the document crimping plate 3 falls toward the office device body 2 by its own weight, Closes securely (θ and φ decrease to zero).

以上の如くヒンジ100を構成することは、以下の如き利点を有する。
第一に、ヒンジ100は従来型ヒンジに比べて部品点数を削減可能である。より詳細には、ヒンジ100は従来型ヒンジにおける巻きバネ、カムスライダ、受圧ピンの三つの部材を省略し、ピン部材を追加することになるため、差し引きで部材を二つ削減することが可能である。
第二に、ヒンジ100および従来型ヒンジはトルクを発生させるメカニズムにおいて根本的に異なり、ヒンジ100はピン部材141L・141Rおよび第二固定部材120(嵌合溝125L・125Rの周辺部分)の弾性変形により第一固定部材110に対する第二固定部材120の回動に抗するトルクを発生させる。そのため、ヒンジ100を構成する他の部材(第一固定部材110、回動軸部材130L・130R)にはトルクを発生させるための力(従来型ヒンジの場合、巻きバネの付勢力)に起因する大きな外力が作用しない。また、ヒンジ100はピン部材141L・141Rおよび第二固定部材120の弾性変形量が小さくても比較的大きなトルクを発生させることが可能である。従って、ヒンジ100は従来型ヒンジに比べて全体としては強度が小さく安価な材料で製造することが可能であり、ひいては製造コストを削減することが可能である。
第三に、ヒンジ100は従来型ヒンジに比べて小型化が容易である。より詳細には、従来型ヒンジの場合、トルク自体を大きくするためには線径および外径が大きい巻きバネを用いる必要があり、巻きバネの外形寸法が大型化する。また、回動角度に応じてトルクの大きさを調整するためには巻きバネの付勢力を大きくしなければならず、ひいては巻きバネの長手方向において巻きバネの伸長・収縮を許容する大きなスペースを確保する必要がある。これに対して、ヒンジ100はピン部材141L・141Rおよび第二固定部材120の弾性変形量を微調整する(例えば、嵌合溝125L・125Rの幅W(φ)を微調整する)だけで第一固定部材110に対する第二固定部材120の回動に抗するトルクの大きさを容易に調整(変更)することが可能である。また、ピン部材141L・141Rの外形寸法も巻きバネに比べて小型化が容易である。
第四に、ヒンジ100は回動角度φに応じてトルクの大きさを容易に調整することが可能である。より詳細には、従来型ヒンジの場合にはヒンジの回動角度と発生するトルクの関係を所望の関係(例えば、フリーストップ機能を達成するような関係)とするためにはカムスライダと受圧ピンとの当接部分の形状を複雑な計算に基づいて決定する必要があり、これらの部材の設計が容易ではないのに対して、ヒンジ100は回動角度φに応じて嵌合溝125L・125Rの幅W(φ)を微調整するだけでトルクの大きさを調整可能である。
このように、ヒンジ100は従来型ヒンジに比べて部品点数の削減、材料コストの低減および小型化を達成しつつ、回動角度に応じてトルクを発生することが可能である。
The construction of the hinge 100 as described above has the following advantages.
First, the hinge 100 can reduce the number of parts compared to the conventional hinge. More specifically, the hinge 100 omits the three members of the winding spring, the cam slider, and the pressure receiving pin in the conventional hinge and adds a pin member, so that two members can be reduced by subtraction. .
Secondly, the hinge 100 and the conventional hinge are fundamentally different in the mechanism for generating torque, and the hinge 100 is elastically deformed by the pin members 141L and 141R and the second fixing member 120 (the peripheral portions of the fitting grooves 125L and 125R). Thus, a torque that resists the rotation of the second fixing member 120 relative to the first fixing member 110 is generated. Therefore, the other members (the first fixing member 110 and the rotating shaft members 130L and 130R) constituting the hinge 100 are caused by a force for generating torque (the urging force of the winding spring in the case of the conventional hinge). Large external force does not work. Further, the hinge 100 can generate a relatively large torque even if the elastic deformation amount of the pin members 141L and 141R and the second fixing member 120 is small. Accordingly, the hinge 100 as a whole can be manufactured with an inexpensive material having a low strength compared to the conventional hinge, and thus the manufacturing cost can be reduced.
Third, the hinge 100 can be easily downsized as compared with the conventional hinge. More specifically, in the case of the conventional hinge, in order to increase the torque itself, it is necessary to use a winding spring having a large wire diameter and outer diameter, and the outer dimensions of the winding spring are increased. In addition, in order to adjust the magnitude of the torque according to the rotation angle, the urging force of the winding spring must be increased, and as a result, a large space allowing the extension and contraction of the winding spring in the longitudinal direction of the winding spring. It is necessary to secure. On the other hand, the hinge 100 only needs to finely adjust the elastic deformation amounts of the pin members 141L and 141R and the second fixing member 120 (for example, finely adjust the width W (φ) of the fitting grooves 125L and 125R). It is possible to easily adjust (change) the magnitude of the torque against the rotation of the second fixing member 120 relative to the one fixing member 110. Further, the external dimensions of the pin members 141L and 141R can be easily reduced as compared with the winding spring.
Fourth, the hinge 100 can easily adjust the magnitude of torque according to the rotation angle φ. More specifically, in the case of a conventional hinge, in order to make the relationship between the rotation angle of the hinge and the generated torque a desired relationship (for example, a relationship that achieves a free stop function), the cam slider and the pressure receiving pin It is necessary to determine the shape of the abutting portion based on complicated calculation, and the design of these members is not easy. On the other hand, the hinge 100 has a width of the fitting grooves 125L and 125R according to the rotation angle φ. The magnitude of the torque can be adjusted only by finely adjusting W (φ).
Thus, the hinge 100 can generate torque according to the rotation angle while achieving a reduction in the number of parts, a reduction in material cost, and a reduction in size as compared with the conventional hinge.

本実施形態では、ピン部材141L・141Rを構成する材料を金属材料(本実施形態ではバネ鋼)とし、嵌合溝125L・125Rが形成される第二固定部材120を構成する材料を樹脂材料(本実施形態ではPOM)としている。
このように構成することにより、ピン部材141L・141Rの外周面と嵌合溝125L・125Rの内周面とが当接したときにピン部材141L・141Rおよび第二固定部材120(嵌合溝125L・125Rの周辺部)がともに弾性変形し、これらの部材間の当接部分における面積が大きくなり、どちらか一方の部材のみが弾性変形する場合に比べて大きな摩擦力(ひいては、トルク)を発生させることが可能である。
また、ピン部材141L・141Rを構成する材料と嵌合溝125L・125Rが形成される第二固定部材120を構成する材料とが異なるため、ピン部材141L・141Rを構成する材料および嵌合溝125L・125Rが形成される第二固定部材120を構成する材料が同じである場合(全て金属材料である場合、あるいは、全て樹脂材料である場合)に比べてこれらの部材間の当接部分における摩耗を低減することが可能である。
In the present embodiment, the material constituting the pin members 141L and 141R is a metal material (spring steel in this embodiment), and the material constituting the second fixing member 120 in which the fitting grooves 125L and 125R are formed is a resin material ( In this embodiment, POM).
With this configuration, when the outer peripheral surface of the pin member 141L / 141R and the inner peripheral surface of the fitting groove 125L / 125R abut, the pin member 141L / 141R and the second fixing member 120 (fitting groove 125L)・ Around the 125R) is elastically deformed, and the area at the contact portion between these members increases, generating a larger frictional force (and thus torque) than when only one of the members is elastically deformed. It is possible to make it.
Further, since the material constituting the pin members 141L and 141R and the material constituting the second fixing member 120 in which the fitting grooves 125L and 125R are formed are different, the material constituting the pin members 141L and 141R and the fitting grooves 125L are different. -Wear in the contact portion between these members as compared to the case where the material constituting the second fixing member 120 on which 125R is formed is the same (when it is all a metal material or when it is all a resin material) Can be reduced.

本実施形態のヒンジ100は二本のピン部材141L・141Rを具備し、第二固定部材120には二本のピン部材141L・141Rがそれぞれ嵌合する二つの(ピン部材141L・141Rと同数の)嵌合溝125L・125Rが形成されるが、本発明はこれに限定されない。
例えば、ヒンジ100よりも発生させるトルクが小さい用途に用いられるヒンジの場合、ヒンジ100におけるピン部材141Rおよび嵌合溝125Rを省略した構成(一本のピン部材141Lを具備するとともに第二固定部材120にはピン部材141Lが嵌合する一つの嵌合溝125Lが形成される構成)としても良い。
The hinge 100 according to the present embodiment includes two pin members 141L and 141R, and the second fixing member 120 has two pin members 141L and 141R (the same number as the pin members 141L and 141R). ) Although the fitting grooves 125L and 125R are formed, the present invention is not limited to this.
For example, in the case of a hinge that is used for an application that generates less torque than the hinge 100, the pin member 141 </ b> R and the fitting groove 125 </ b> R in the hinge 100 are omitted (the second fixing member 120 is provided with a single pin member 141 </ b> L). May be configured such that one fitting groove 125L into which the pin member 141L is fitted is formed.

また、本実施形態ではピン部材141L・141Rの本数(二本)と第二固定部材120に形成される嵌合溝125L・125Rの数(二つ)が同数である(ピン部材と嵌合溝とが一対一で対応している)が、本発明はこれに限定されない。例えば、一本のピン部材の中央部を第一固定部材に固定するとともにピン部材の両端部を第二固定部材に形成された二つの嵌合溝にそれぞれ嵌合させても良く、一つの嵌合溝に二本以上のピン部材が嵌合しても良い。   In this embodiment, the number (two) of the pin members 141L and 141R and the number (two) of the fitting grooves 125L and 125R formed in the second fixing member 120 are the same (the pin member and the fitting groove). However, the present invention is not limited to this. For example, the center portion of one pin member may be fixed to the first fixing member, and both end portions of the pin member may be fitted into two fitting grooves formed on the second fixing member, respectively. Two or more pin members may be fitted in the groove.

本実施形態では第一固定部材110を事務機器本体2に固定し、第二固定部材120を原稿圧着板3に固定するが、本発明はこれに限定されない。例えば、第一固定部材110を原稿圧着板3に固定し、第二固定部材120を事務機器本体2に固定することも可能である。   In the present embodiment, the first fixing member 110 is fixed to the office equipment body 2 and the second fixing member 120 is fixed to the original cover 3. However, the present invention is not limited to this. For example, the first fixing member 110 can be fixed to the original cover 3 and the second fixing member 120 can be fixed to the office equipment body 2.

The left half of the pin member 242R is inserted into the pin hole 213R of the first fixing member 210, and the pin member 241R is fixed to the first fixing member 210 so as not to drop off.
As shown in FIG. 12, when the pin members 241L, 241R, 242L, and 242R are fixed to the first fixing member 210, the axes of the rotating shaft members 230L and 230R, the axes of the pin members 241L and 241R, and the pin members 242L and 242R (In this embodiment, the axis of the rotary shaft members 230L and 230R, the axis of the pin members 241L and 241R, and the axis of the pin members 242L and 242R are all parallel in the left-right direction).
As shown in FIG. 10, the left half portions of the pin members 241L and 242L fixed to the first fixing member 210 are fitted in the fitting grooves 225L and 226L of the second fixing member 220, respectively. Similarly, as shown in FIG. 11, the right half portions of the pin members 241R and 242R fixed to the first fixing member 210 are fitted in the fitting grooves 225R and 226R of the second fixing member 220, respectively.

ヒンジ200についてもヒンジ100と同様に、ヒンジ200の回動角度φが17°よりも大きくかつ90°以下であるときにはピン部材241L・241R・242L・242Rの外周面がそれぞれ嵌合溝225L・225R・226L・226Rの内周面の二箇所に当接する。このとき、ピン部材241L・241R・242L・242Rにおいて嵌合溝225L・225R・226L・226Rに嵌合する部分はピン部材241L・241R・242L・242Rの半径方向に弾性変形し、第二固定部材220の嵌合溝225L・225R・226L・226Rの内周面においてピン部材241L・241R・242L・242Rの外周面に当接する部分の周辺が弾性変形する。
その結果、ピン部材241L・241R・242L・242R(の外周面)と嵌合溝225L・225R・226L・226R(の内周面)とが強く当接し、かつピン部材241L・241R・242L・242Rおよび嵌合溝225L・225R・226L・226Rにおいて当接する部分の面積が大きくなるので、ピン部材241L・241R・242L・242Rおよび嵌合溝225L・225R・226L・226Rの内周面の当接部分に摩擦力が発生し、当該摩擦力が第一固定部材210に対する第二固定部材220の回動に抗するトルクとなる。
Similarly to the hinge 100, the hinge 200 has the outer peripheral surfaces of the pin members 241L, 241R, 242L, and 242R fitted in the fitting grooves 225L and 225R, respectively, when the rotation angle φ of the hinge 200 is greater than 17 ° and 90 ° or less. -Abuts at two locations on the inner peripheral surface of 226L and 226R. At this time, the portions of the pin members 241L, 241R, 242L, and 242R that fit into the fitting grooves 225L, 225R, 226L, and 226R are elastically deformed in the radial direction of the pin members 241L, 241R, 242L, and 242R, and the second fixing member In the inner peripheral surfaces of the fitting grooves 225L, 225R, 226L, and 226R of 220, the periphery of the portion that contacts the outer peripheral surface of the pin member 241L, 241R, 242L, and 242R is elastically deformed.
As a result, the pin members 241L, 241R, 242L, and 242R (the outer peripheral surfaces thereof) and the fitting grooves 225L, 225R, 226L, and 226R (the inner peripheral surfaces thereof) are in strong contact, and the pin members 241L, 241R, 242L, and 242R are in contact. Further, since the area of the abutting portion in the fitting grooves 225L, 225R, 226L, and 226R increases, the abutting portions of the inner peripheral surfaces of the pin members 241L, 241R, 242L, and 242R and the fitting grooves 225L, 225R, 226L, and 226R A frictional force is generated, and the frictional force becomes a torque that resists the rotation of the second fixing member 220 relative to the first fixing member 210.

図12に示す如く、ピン部材241L・242Lが第一固定部材210に固定されたとき、ピン部材241L・242Lの回動軸部材230L・230Rの軸線回りにおける位相差は均等となり、位相が互いに180°ずれている。
同様に、ピン部材241R・242Rが第一固定部材210に固定されたとき、ピン部材241R・242Rの回動軸部材230L・230Rの軸線回りにおける位相差は均等となり、位相が互いに180°ずれている。
従って、ピン部材241Lの外周面と第二固定部材220の嵌合溝225Lの内周面との当接部分に作用する力と、ピン部材242Lの外周面と第二固定部材220の嵌合溝226Lの内周面との当接部分に作用する力と、は回動軸部材230L・230Rの軸線を中心として対称形となる。同様に、ピン部材241Rの外周面と第二固定部材220の嵌合溝225Rの内周面との当接部分に作用する力と、ピン部材242Rの外周面と第二固定部材220の嵌合溝226Rの内周面との当接部分に作用する力と、は回動軸部材230L・230Rの軸線を中心として対称形となる。
このように、ヒンジ200は先に説明したヒンジ100の利点に加えて、対称形となる力同士が相殺することにより回動軸部材230L・230Rに作用する外力(負荷)が低減されるという利点も有する。
As shown in FIG. 12, when the pin members 241L and 242L are fixed to the first fixing member 210, the phase differences of the pin members 241L and 242L around the axis of the rotation shaft members 230L and 230R are equal, and the phases are 180 with respect to each other. ° Deviation.
Similarly, when the pin members 241R and 242R are fixed to the first fixing member 210, the phase differences of the pin members 241R and 242R around the axis of the rotating shaft members 230L and 230R are equal, and the phases are shifted from each other by 180 °. Yes.
Therefore, the force acting on the contact portion between the outer peripheral surface of the pin member 241L and the inner peripheral surface of the fitting groove 225L of the second fixing member 220, and the fitting groove of the outer peripheral surface of the pin member 242L and the second fixing member 220 The force acting on the abutting portion with the inner peripheral surface of 226L is symmetrical about the axis of the rotating shaft member 230L / 230R. Similarly, the force acting on the contact portion between the outer peripheral surface of the pin member 241R and the inner peripheral surface of the fitting groove 225R of the second fixing member 220, and the fitting between the outer peripheral surface of the pin member 242R and the second fixing member 220 The force acting on the contact portion of the groove 226R with the inner peripheral surface is symmetric with respect to the axis of the rotation shaft member 230L / 230R.
Thus, in addition to the advantages of the hinge 100 described above, the hinge 200 has an advantage that external forces (loads) acting on the rotating shaft members 230L and 230R are reduced by canceling the symmetrical forces. Also have.

本実施形態では二本のピン部材241L・242Lが回動軸部材230L・230Rの軸線回りにおける位相差が均等となるように配置されるが、本発明はこれに限定されない。
すなわち、回動軸部材に作用する外力(負荷)を低減する観点からは、複数本のピン部材が第一固定部材に固定されたとき、複数本のピン部材のうち隣り合うピン部材の回動軸部材の軸線回りにおける位相差を均等とする(位相差を(360/ピンの本数)°とする)ことが望ましい。
In the present embodiment, the two pin members 241L and 242L are arranged so that the phase differences around the axis of the rotating shaft members 230L and 230R are equal, but the present invention is not limited to this.
That is, from the viewpoint of reducing the external force (load) acting on the rotation shaft member, when a plurality of pin members are fixed to the first fixing member, the rotation of adjacent pin members among the plurality of pin members is performed. It is desirable that the phase difference around the axis of the shaft member be equal (the phase difference is (360 / number of pins) °).

その結果、ピン部材341L・341R・342L・342R(の外周面)と嵌合溝325L・325R・326L・326R(の内周面)とが強く当接し、かつピン部材341L・341R・342L・342Rおよび嵌合溝325L・325R・326L・326Rにおいて当接する部分の面積が大きくなるので、ピン部材341L・341R・342L・342Rおよび嵌合溝325L・325R・326L・326Rの内周面の当接部分に摩擦力が発生し、当該摩擦力が第一固定部材310に対する第二固定部材320の回動に抗するトルクとなる。
Similarly to the hinge 100 and the hinge 200, the outer peripheral surfaces of the pin members 341L, 341R, 342L, and 342R are fitted into the fitting grooves when the rotation angle φ of the hinge 300 is larger than 17 ° and not larger than 90 °. 325L, 325R, 326L and 326R are in contact with two locations on the inner peripheral surface. At this time, the portions of the pin members 341L, 341R, 342L, and 342R that fit into the fitting grooves 325L, 325R, 326L, and 326R are elastically deformed in the radial direction of the pin members 341L, 341R, 342L, and 342R, and the second fixing member In the inner peripheral surfaces of 320 fitting grooves 325L, 325R, 326L, and 326R, the periphery of the portion that contacts the outer peripheral surface of the pin member 341L, 341R, 342L, and 342R is elastically deformed.
As a result, the pin members 341L, 341R, 342L, and 342R (the outer peripheral surface thereof) and the fitting grooves 325L, 325R, 326L, and 326R (the inner peripheral surface thereof) are in strong contact, and the pin members 341L, 341R, 342L, and 342R are in contact. Further, since the area of the abutting portion in the fitting grooves 325L, 325R, 326L, and 326R is increased, the abutting portions of the inner peripheral surfaces of the pin members 341L, 341R, 342L, and 342R and the fitting grooves 325L, 325R, 326L, and 326R A frictional force is generated, and the frictional force becomes a torque that resists the rotation of the second fixing member 320 relative to the first fixing member 310.

図18に示す如く、ピン部材341L・342Lが第一固定部材310に固定されたとき、ピン部材341L・342Lの仮想回動軸線6回りにおける位相差は均等となり、位相が互いに180°ずれている。同様に、ピン部材341R・342Rが第一固定部材310に固定されたとき、ピン部材341R・342Rの仮想回動軸線6回りにおける位相差は均等となり、位相が互いに180°ずれている。
従って、ピン部材341Lの外周面と第二固定部材320の嵌合溝325Lの内周面との当接部分に作用する力と、ピン部材342Lの外周面と第二固定部材320の嵌合溝326Lの内周面との当接部分に作用する力と、は仮想回動軸線6を中心として対称形となる。同様に、ピン部材341Rの外周面と第二固定部材320の嵌合溝325Rの内周面との当接部分に作用する力と、ピン部材342Rの外周面と第二固定部材320の嵌合溝326Rの内周面との当接部分に作用する力と、は仮想回動軸線6を中心として対称形となる。
このように、ヒンジ300はピン部材341L・341R・342L・342Rと第二固定部材320との間に作用する力を対称形として相殺することにより第二固定部材320が第一固定部材310に対して回動するときに仮想回動軸線6がぶれることを防止し、ひいては(専ら回動軸としての機能を果たす部材が省略されているにも関わらず)滑らかに回動することが可能であるという利点を有する。
As shown in FIG. 18, when the pin members 341L and 342L are fixed to the first fixing member 310, the phase differences around the virtual rotation axis 6 of the pin members 341L and 342L are equal, and the phases are shifted from each other by 180 °. . Similarly, when the pin members 341R and 342R are fixed to the first fixing member 310, the phase differences around the virtual rotation axis 6 of the pin members 341R and 342R are equal and the phases are shifted from each other by 180 °.
Accordingly, the force acting on the contact portion between the outer peripheral surface of the pin member 341L and the inner peripheral surface of the fitting groove 325L of the second fixing member 320, and the fitting groove of the outer peripheral surface of the pin member 342L and the second fixing member 320 The force acting on the abutting portion with the inner peripheral surface of 326L is symmetric about the virtual rotation axis 6. Similarly, the force acting on the contact portion between the outer peripheral surface of the pin member 341R and the inner peripheral surface of the fitting groove 325R of the second fixing member 320, and the fitting between the outer peripheral surface of the pin member 342R and the second fixing member 320 The force acting on the contact portion of the groove 326 </ b> R with the inner peripheral surface is symmetric about the virtual rotation axis 6.
In this way, the hinge 300 cancels out the force acting between the pin members 341L, 341R, 342L, and 342R and the second fixing member 320 as a symmetrical shape, so that the second fixing member 320 is moved relative to the first fixing member 310. Thus, it is possible to prevent the virtual rotation axis 6 from being shaken when rotating, and to smoothly rotate (although the member that exclusively functions as the rotation axis is omitted). Has the advantage.
