Description
本発明は屋内の扉用レバーハンドルに係り、殊更その握りバーにおける着色カラーの濃淡度又は明暗度が、これに当る光の方角やこれを見る方角によって興趣変化し、高い格調(高級感)の飽きない動的装飾効果を演出し得るように工夫したものである。 The present invention relates to an indoor door lever handle, and in particular, the shade or brightness of the colored color in the grip bar changes according to the direction of the light hitting it or the direction of viewing it, and has a high tone (high quality). It is devised to produce a dynamic decoration effect that never gets tired.
屋内の扉用レバーハンドルは、扉に取り付けられてラッチボルトを操作するブラケットと、その取付ブラケットの頭部からほぼL字型に張り出して、扉に沿い延在する一定長さの握りバーとを備えている通例である。 An indoor door lever handle has a bracket that is attached to the door and operates a latch bolt, and a grip bar of a fixed length that extends from the head of the mounting bracket into a substantially L shape and extends along the door. It is a common practice.
その握りバーの装飾効果を昂めるために提案されている各種特許文献のうち、特開2000−356053号発明が握りバー(把持体)として透明又は半透明の筒体を採用しており、その筒体に凸レンズ効果を持たせている点で、本発明に最も近似する公知技術であると考えられる。
ところが、上記特開2000−356053号発明の第1、2実施形態(図1〜5)に示された構成では、把持体である透明又は半透明の筒体(6)と、その筒体(把持体)(6)の芯材となる軸部(4)のほかに、適宜の模様(13)が印刷された別個な合成樹脂フィルムや布、紙などの柔軟性装飾シート(5)も準備した上、これを模様(13)が表側となるように丸めて、上記筒体(把持体)(6)の内部へ挿入セットしなければならない。 However, in the configuration shown in the first and second embodiments (FIGS. 1 to 5) of the invention of the above Japanese Patent Laid-Open No. 2000-356053, a transparent or translucent cylinder (6) as a gripping body and its cylinder ( A flexible decorative sheet (5) such as a separate synthetic resin film, cloth or paper on which an appropriate pattern (13) is printed is prepared in addition to the shaft (4) which is the core of the gripping body (6). In addition, this must be rounded so that the pattern (13) is on the front side and inserted and set into the cylinder (gripping body) (6).
この点、柔軟な装飾シート(5)が布である場合には、筒体(把持体)(6)の内部へ丸めて挿入セットしても、その表面が筒体(把持体)(6)の内面に密着することは困難であり、その挿入セット状態の正確さや安定性に劣る。 In this regard, when the flexible decorative sheet (5) is a cloth, the surface of the flexible decorative sheet (5) can be rolled into the cylinder (gripping body) (6) and inserted into the cylinder (gripping body) (6). It is difficult to be in close contact with the inner surface, and the accuracy and stability of the inserted set state are inferior.
又、上記装飾シート(5)の模様(13)が隠蔽されてしまうことを予防すべく、その筒体(把持体)(6)の両端部を一対の係止リング(18)(19)によって、ハンドル本体(3)とグリップエンド(7)へかぶせ付け状態に固定維持する必要があり、茲に係止リング(18)(19)の一対とグリップエンド(7)も不可欠な構成部品として、その組立部品点数が増加すると共に、組立作業が煩雑化するため、扉用レバーハンドル(ハンドル部材)の量産効果を最大限に発揮させることができず、握りバー(把持体)の表面に発生する段差部が、握り持ち使用上の違和感を与えるおそれもある。 Further, in order to prevent the pattern (13) of the decorative sheet (5) from being concealed, both ends of the cylindrical body (gripping body) (6) are attached by a pair of locking rings (18) (19). The handle body (3) and the grip end (7) need to be fixed and maintained. A pair of locking rings (18) and (19) and the grip end (7) are also indispensable components. As the number of assembly parts increases and the assembly work becomes complicated, the mass production effect of the lever handle (handle member) for the door cannot be maximized and occurs on the surface of the grip bar (grip body). The stepped portion may give a sense of incongruity in gripping use.
それにもまして、上記装飾シート(5)に印刷された模様(13)を、その透明又は半透明な筒体(把持体)(6)の外部から透視するようになっており、予じめ選択される模様(13)自体の装飾効果を与えるに過ぎない構成であるため、たとえ上記筒体(把持体)(6)の凸レンズ機能により、その模様(13)を浮き上がらせ拡大するとしても、これに当る光の方角やこれを見る方角によって、上記模様(13)の興趣変化することは起らず、誰もが飽きやすい静的・単調な装飾効果を得られるにとどまる。その誰もが飽きない普遍性と、建物の内装材や扉などと融和した高い格調(高級感)の斬新な装飾効果を演出できないのである。 In addition, the pattern (13) printed on the decorative sheet (5) is seen through from the outside of the transparent or translucent cylinder (grip body) (6), and is selected in advance. Since the pattern (13) itself is merely a decorative effect, even if the pattern (13) is lifted and enlarged by the convex lens function of the cylinder (grip body) (6), this The interest of the pattern (13) does not change depending on the direction of the light hitting or the direction of viewing it, and only a static and monotonous decoration effect that everyone can get tired of can be obtained. The universality that nobody gets tired of, and a high-class (luxurious) novel decoration effect that is compatible with the interior materials and doors of the building cannot be produced.
そして、このような興趣変化に富む装飾効果については、芯材(10)と一対の装飾体(5a)(5b)並びに一対の把持体(6a)(6b)を、対応的な異形断面の金属製組立部品として、その芯材(20)へ装飾体(5a)(5b)と把持体(6a)(6b)との一対づつを、順次被着一体化させた第3実施形態(図6、7)の構成や、上記第1、2実施形態の別個な装飾シート(5)や上記第3実施形態の別個な装飾体(5a)(5b)を省略して、把持体(6a)(6b)の内面に対する塗装又はメッキにより、模様(13)付きの装飾層(23a)(23b)を形成した第4実施形態(図8、9)の構成においても、到底期待することができない。 And about such a decorative effect rich in interest, the core material (10) and the pair of decorative bodies (5a) and (5b) and the pair of gripping bodies (6a) and (6b) are made of metal with corresponding irregular cross sections. As a manufactured assembly part, a third embodiment (FIG. 6, FIG. 6), in which a pair of decorative bodies (5a) (5b) and grip bodies (6a) (6b) is sequentially attached and integrated to the core (20). 7), the separate decorative sheet (5) of the first and second embodiments and the separate decorative body (5a) (5b) of the third embodiment are omitted, and the gripping bodies (6a) (6b) are omitted. In the configuration of the fourth embodiment (FIGS. 8 and 9) in which the decorative layers (23a) and (23b) with the pattern (13) are formed by painting or plating on the inner surface of).
本発明はこのような課題の解決を目的としており、その目的を達成するために、請求項1では屋内の扉に対する取付ブラケットと、その取付ブラケットの頭部から扉に沿って張り出し延在する一定長さの握りバーとを備えた扉用レバーハンドルにおいて、
SUMMARY OF THE INVENTION The present invention aims to solve such problems, and in order to achieve the object, in
上記取付ブラケットをその頭部が円弧凸曲面として丸味のある角柱型に造形し、 The mounting bracket is shaped into a round prismatic shape whose head is an arc convex curved surface,
上記握りバーを芯棒とその別個な化粧カバーに分割して、その芯棒をステンレス鋼やアルミ合金などの金属から、上記取付ブラケットの円弧凸曲面と面一な円弧凸曲面を頭部に有する断面長方形の角棒状として、その取付ブラケットと連続一体に造形する一方、 The grip bar is divided into a core rod and a separate decorative cover, and the core rod is made of a metal such as stainless steel or aluminum alloy, and the head has an arc convex curved surface that is flush with the arc convex curved surface of the mounting bracket. While shaped as a rectangular bar with a rectangular cross section, it is molded integrally with its mounting bracket,
上記化粧カバーを着色顔料が含有された光透過性の合成樹脂から、上記芯棒と対応する断面U字型の差込み溝が開口延在する丸棒状に一体成形すると共に、The decorative cover is integrally molded from a light-transmitting synthetic resin containing a color pigment into a round bar shape having an insertion groove having a U-shaped cross section corresponding to the core rod, and extending.
その化粧カバーにおける差込み溝の差し込み嵌合によって被覆されることとなる芯棒の円弧凸曲面を除くフラットな3辺面を、メッキや塗装、真空蒸着などの表面処理によりシルバーメタリック調又はゴールドメタリック調の光反射面として仕上げ、The flat three sides except for the arc convex curved surface of the core rod, which is covered by the insertion fitting of the insertion groove in the decorative cover, are made of silver metallic tone or gold metallic tone by surface treatment such as plating, painting, vacuum deposition, etc. Finish as a light reflecting surface,
上記握りバーの丸棒状化粧カバーから角棒状芯棒の光反射面に入射する光の方角やこれを見る方角により、その化粧カバーにおける着色カラーの濃淡度又は明暗度が自づと変化するように定めたことを特徴とする。Depending on the direction of the light incident on the light reflecting surface of the square bar-shaped core rod from the round bar-shaped decorative cover of the grip bar and the direction of viewing the same, the shade or brightness of the colored color in the decorative cover may change by itself. It is characterized by having decided.
又、請求項2では角棒状芯棒の張り出し先端部だけに、頭部の円弧凸曲面とほぼ対称な化粧カバー抜け止め用となる円弧凸曲片を突設する一方、Further, in claim 2, an arc-shaped curved piece for preventing a decorative cover from coming off is provided almost only symmetrically with the arc-shaped curved surface of the head, only on the projecting tip portion of the square-shaped core rod,
その芯棒の円弧凸曲片と嵌合する凹段面を、化粧カバーにおける断面U字型差込み溝の溝底面に対応形成して、A concave step surface to be fitted to the arc-shaped convex piece of the core rod is formed corresponding to the groove bottom surface of the U-shaped insertion groove in the cross section of the decorative cover,
上記化粧カバーの差込み溝を芯棒の底側から差し込み嵌合させて、その化粧カバーを複数の固定ビスにより、上記芯棒との全体的な丸棒型をなす握りバーに組み立て一体化したことを特徴とする。The insertion groove of the decorative cover is inserted and fitted from the bottom side of the core rod, and the decorative cover is assembled and integrated with a grip bar that forms an overall round bar shape with the core rod by a plurality of fixing screws. It is characterized by.
請求項1の上記構成によれば、扉用レバーハンドルの握りバーが剛性な金属製の芯棒と、これを被覆する別個な合成樹脂製の化粧カバーとから成り、その芯棒は扉への取付ブラケットと連続一体に造形されているため、レバーハンドルとしての充分な耐久強度を確保できる効果がある。According to the said structure of
しかも、上記金属製の芯棒がその化粧カバーによって被覆される内部の表面は、シルバーメタリック調又はゴールドメタリック調の光反射面として仕上げ処理されている一方、上記化粧カバーが着色顔料を含有する光透過性の合成樹脂から丸棒状に一体成形されているため、上記握りバーへ使用中に当る光の方角や、これを見る方角の如何により、化粧カバーにおける着色カラーの濃淡度又明暗度が、その内部から上記光反射面の光反射作用を受けて自づと変化することになり、上記丸棒状化粧カバーの凸レンズ機能とも相俟って、興趣変化に富む優美な装飾効果を得られるのである。Moreover, the inner surface of the metallic core covered with the decorative cover is finished as a silver metallic or gold metallic light reflecting surface, while the decorative cover contains a light pigment. Since the synthetic resin is integrally formed in a round bar shape, depending on the direction of the light hitting the grip bar during use and the direction of viewing it, the shade or brightness of the colored color in the decorative cover is The light reflecting action of the light reflecting surface from the inside changes itself, and in combination with the convex lens function of the round bar-shaped decorative cover, an elegant decoration effect rich in excitement can be obtained.
又、このような装飾効果を得るための構成としても、冒頭の特開2000−356053号発明が具備する特別な装飾シートや、その面倒な挿入セット作業を一切必要としない。Also, the configuration for obtaining such a decoration effect does not require any special decoration sheet provided in the opening Japanese Patent Application Laid-Open No. 2000-356053 or the troublesome insertion and setting work.
この点、特開2000−356053号発明の装飾効果は、装飾シートに印刷された模様自体の静的なそれであるため、その装飾シートを交換しない限り、別異の装飾効果を得ることはできないが、本発明の構成では化粧カバーを交換しなくとも、その芯棒の光反射面に入射する光の方角やこれを見る方角によって、その化粧カバーの着色カラーが濃く(暗く)又は淡く(明るく)自づと興趣変化する動的な装飾効果を演出できるのである。In this respect, the decoration effect of the invention of Japanese Patent Laid-Open No. 2000-356053 is a static one of the pattern itself printed on the decoration sheet. Therefore, unless the decoration sheet is replaced, a different decoration effect cannot be obtained. In the configuration of the present invention, even if the decorative cover is not replaced, the colored color of the decorative cover is dark (dark) or light (bright) depending on the direction of light incident on the light reflecting surface of the core rod and the direction of viewing the light. It is possible to produce a dynamic decoration effect that changes itself and interests.
更に、握りバーの芯棒が断面長方形の角棒状をなし、その化粧カバーにより被覆されることとなるフラットな3辺面が、シルバーメタリック調又はゴールドメタリック調の光反射面として表面処理されている一方、化粧カバーは凸レンズとして機能し得る丸棒状に造形されているため、言わば角棒状芯棒と丸棒状化粧カバーとの組み合わせにより、上記濃淡度又は明暗度の興趣変化する装飾効果をますます昂めることができる。Furthermore, the core bar of the grip bar has a rectangular bar shape with a rectangular cross section, and the three flat sides to be covered with the decorative cover are surface-treated as light reflecting surfaces in silver metallic tone or gold metallic tone. Because the decorative cover is shaped like a round bar that can function as a convex lens, the combination of a square bar-shaped core bar and a round bar-shaped decorative cover, so to speak, is increasingly complimenting the decorative effect of changing the above shade or brightness. Can.
請求項2の構成を採用するならば、握りバーの芯棒とその化粧カバーとを表面全体の均斉な丸棒型に組み立て一体化することができ、握り持ち使用上の安全性に役立つほか、上記芯棒が化粧カバーの断面U字型差込み溝から露出する表面を、握りバーの長手方向に沿い延在する言わば筋骨として、意匠的なアクセント効果を与え得る利点もある。If the construction of claim 2 is adopted, the core bar of the grip bar and its decorative cover can be assembled and integrated into a uniform round bar shape over the entire surface, which is useful for safety in gripping use, There is also an advantage that a design accent effect can be given by using the surface exposed from the cross-sectional U-shaped insertion groove of the decorative cover as a muscular bone extending along the longitudinal direction of the grip bar.
又、芯棒の円弧凸曲片とその化粧カバーの凹段面との差し込み嵌合により、化粧カバーが芯棒の長手方向に沿って抜け出すおそれを防止できるほか、その芯棒の円弧凸曲片を言わば調芯ガイドとして、これに沿い化粧カバーの断面U字型差込み溝を芯棒へ、自づと正しく円滑に差し込み嵌合することもでき、その組立作業性の向上に役立つ。In addition, by inserting and fitting the arc-shaped convex piece of the core rod and the concave step surface of the decorative cover, it is possible to prevent the decorative cover from coming out along the longitudinal direction of the core rod, and the arc-shaped convex piece of the core rod. In other words, as a centering guide, the U-shaped insertion groove of the decorative cover can be properly and smoothly inserted and fitted into the core bar along this, which helps to improve the assembling workability.
以下、図面に基いて本発明の具体的構成を詳述すると、先ず図1〜12は本発明に係る扉用レバーハンドル(A)の第1実施形態を示しており、これは言うまでもなく屋内の扉(D)に対する取付ブラケット(B)と、これから扉(D)に沿って張り出し延在する握りバー(G)とを備え、全体としてほぼL字型を呈しているが、茲に握りバー(G)は本発明の場合、取付ブラケット(B)と連続一体の芯棒(11)と、これを被覆する別個な化粧カバー(12)とから成り立っている。Hereinafter, specific configurations of the present invention will be described in detail with reference to the drawings. First, FIGS. 1 to 12 show a first embodiment of a door lever handle (A) according to the present invention. It has a mounting bracket (B) for the door (D) and a grip bar (G) extending over the door (D). The grip bar (G) is almost L-shaped as a whole. In the case of the present invention, G) consists of a mounting bracket (B) and a continuous and integral core rod (11) and a separate decorative cover (12) covering the same.
そして、その取付ブラケット(B)と握りバー(G)の芯棒(11)とが、ステンレス鋼やアルミ合金、その他の剛性な金属製品として、次のとおり連続一体に造形されている。The mounting bracket (B) and the core bar (11) of the grip bar (G) are continuously and integrally formed as stainless steel, aluminum alloy, and other rigid metal products as follows.
即ち、上記扉用レバーハンドル(A)の取付ブラケット(B)はほぼ正方形(例えば約22mm×約22mm)の角柱状をなし、一定の取付高さ(H1)(例えば約53mm)を有するが、その頭部だけの円弧凸曲面(13)として丸味が与えられている。(14)は同じく取付ブラケット(B)のフラットな根元部から連続的に張り出す径小な円盤であり、扉(D)の化粧台座(15)へ差し込み嵌合されることになる。That is, the mounting bracket (B) of the door lever handle (A) has a substantially square prism shape (for example, about 22 mm × about 22 mm), and has a fixed mounting height (H1) (for example, about 53 mm). The roundness is given as an arc convex curved surface (13) of only the head. Similarly, (14) is a small-diameter disk continuously projecting from the flat base portion of the mounting bracket (B), and is inserted and fitted into the decorative base (15) of the door (D).
又、(16)はその円盤(14)から取付ブラケット(B)の中心線上に沿って、一定深さ(H2)(例えば約34mm)だけ穿設されたほぼ正方形の軸穴であり、ここにはラッチボルトの出没機構(図示省略)を構成するラッチ操作軸(ハンドルカム軸)(17)が差し込み嵌合されることになる。(18)はそのラッチ操作軸(17)を固定するピン挿入穴であり、円形又は楕円形に開口されている。Further, (16) is a substantially square shaft hole drilled from the disk (14) along the center line of the mounting bracket (B) by a certain depth (H2) (for example, about 34 mm). The latch operating shaft (handle cam shaft) (17) constituting the latch bolt retracting mechanism (not shown) is inserted and fitted. (18) is a pin insertion hole for fixing the latch operating shaft (17), which is opened in a circular or elliptical shape.
そして、握りバー(G)の芯棒(11)は図1〜9から明白なように、上記取付ブラケット(B)における頭部の円弧凸曲面(13)と面一な円弧凸曲面(19)を備えたほぼ長方形(例えば厚み:約8mm×深さ:約14mm)の角棒として、その取付ブラケット(B)から一定長さ(L)(例えば約115mm)だけ直線的に張り出し延在している。The core rod (11) of the grip bar (G) is, as is apparent from FIGS. 1 to 9, an arc convex surface (19) flush with the arc convex surface (13) of the head of the mounting bracket (B). As a rectangular bar having a rectangular shape (for example, thickness: about 8 mm × depth: about 14 mm), it extends linearly from the mounting bracket (B) by a certain length (L) (for example, about 115 mm). Yes.
(20)はその芯棒(11)のフラットな底面に開口分布された複数のネジ穴、(21)は同じく芯棒(11)の張り出し先端部に位置しつつ、その底面から上記円弧凸曲面(19)とほぼ対称に突出された円弧凸曲片であり、上記芯棒(11)の長手方向に沿う化粧カバー(12)の抜け止めストッパーとして働くほか、その芯棒(11)に対する化粧カバー(12)の円滑な差し込み調芯ガイドとしても機能し得る。(20) is a plurality of screw holes distributed on the flat bottom surface of the core rod (11), and (21) is located at the projecting tip of the core rod (11), and the arc convex curved surface from the bottom surface. (19) is an arc-shaped convex piece projecting almost symmetrically with (19), and serves as a stopper for preventing the decorative cover (12) along the longitudinal direction of the core rod (11), as well as a decorative cover for the core rod (11) It can also function as a smooth insertion alignment guide of (12).
握りバー(G)の芯棒(11)が剛性な金属製として、ほぼ長方形の角棒状に造形されていることを上記したが、その化粧カバー(12)により被覆されることとなる芯棒(11)のフラットな3辺面は、特にメッキや塗装、真空蒸着、スパッタリングなどの各種表面処理により、シルバーメタリック調又はゴールドメタリック調の光反射面(22a)(22b)(22c)として仕上げられている。As described above, the core bar (11) of the grip bar (G) is made of a rigid metal and is shaped like a substantially rectangular square bar, but the core bar (12) covered by the decorative cover (12) The flat three side surfaces of 11) are finished as light reflecting surfaces (22a), (22b) and (22c) of silver metallic tone or gold metallic tone by various surface treatments such as plating, painting, vacuum deposition and sputtering. .
他方、同じく握りバー(G)の上記化粧カバー(12)はその芯棒(11)との相関々係上、適当な着色顔料を含有する透明の合成樹脂や好ましくは半透明の合成樹脂から、次のとおり射出成形されている。このような合成樹脂としては、光透過性を有するならば、特に限定されず、スチロール樹脂やAS樹脂などのスチレン系樹脂を初め、メタクリル系樹脂、カーボネート系樹脂、ポリエチレンテレフタレート樹脂などを挙げることができ、又建物の内装材や扉などと調和する褐色や、その他の適当な着色顔料に代えて、光拡散剤を含有させることにより、乳白色の着色カラーを与えても良い。On the other hand, the decorative cover (12) of the grip bar (G) is made of a transparent synthetic resin containing an appropriate coloring pigment, preferably a translucent synthetic resin, in relation to the core bar (11). It is injection molded as follows. Such a synthetic resin is not particularly limited as long as it has optical transparency, and examples thereof include styrene resins such as styrene resins and AS resins, methacrylic resins, carbonate resins, and polyethylene terephthalate resins. Alternatively, a milky white colored color may be provided by incorporating a light diffusing agent in place of brown or other suitable coloring pigments in harmony with the interior materials and doors of the building.
即ち、握りバー(G)の化粧カバー(12)は図1〜9から明白なように、上記芯棒(11)の円弧凸曲面(19)と面一状態になる丸棒型(例えば直径:約20mm)として、しかもその長手中心線上に沿い開口する断面U字状の差込み溝(23)を備えており、その差込み溝(23)が上記芯棒(11)へ差し込み嵌合されて、その芯棒(11)の上記光反射面(22a)(22b)(22c)を被覆するようになっている。That is, as apparent from FIGS. 1 to 9, the decorative cover (12) of the grip bar (G) is a round bar type (for example, diameter :) that is flush with the arcuate curved surface (19) of the core rod (11). About 20 mm), and has an insertion groove (23) having a U-shaped cross section that opens along the longitudinal center line. The insertion groove (23) is inserted and fitted into the core rod (11). The light reflecting surface (22a) (22b) (22c) of the core rod (11) is covered.
その場合、芯棒(11)の張り出し先端部には円弧凸曲片(21)が突出しているため、その差し込み調芯ガイド作用により、ここから先行して化粧カバー(12)の差込み溝(23)を、上記芯棒(11)へ正しく円滑に差し込み嵌合させることができる。In that case, since the arc-shaped curved piece (21) protrudes from the projecting tip of the core rod (11), the insertion groove (23) of the decorative cover (12) precedes from here due to the insertion alignment guide action. ) Can be correctly and smoothly inserted and fitted into the core rod (11).
又、化粧カバー(12)における芯棒(11)の被覆部分は、先に例示した数値との関係上、比較的大きな約5〜6mmの一定厚み(T)を保っており、それ自体が透明又は半透明であることとも相俟ち、凸レンズとして機能し得る。尚、上記芯棒(11)の円弧凸曲面(19)は言わば背骨として露出状態にあり、握りバー(G)に意匠上のアクセント効果を与えることができる。In addition, the covering portion of the core rod (11) in the decorative cover (12) has a relatively large constant thickness (T) of about 5 to 6 mm in relation to the numerical values exemplified above, and is itself transparent. Alternatively, it is also translucent and can function as a convex lens. The arc-shaped curved surface (19) of the core rod (11) is in an exposed state as a spine, and can give a design accent effect to the grip bar (G).
(24)は化粧カバー(12)における差込み溝(23)の溝底面に貫通形成された複数のビス挿入穴であって、上記芯棒(11)のネジ穴(20)と対応位置し、ここからネジ穴(20)ヘ螺合締結する固定ビス(25)によって、その芯棒(11)へ化粧カバー(12)が取り付け一体化されることとなる。(24) is a plurality of screw insertion holes formed through the groove bottom surface of the insertion groove (23) in the decorative cover (12), and is located corresponding to the screw hole (20) of the core rod (11). The decorative cover (12) is attached to and integrated with the core rod (11) by the fixing screw (25) that is screwed into the screw hole (20).
その固定ビス(25)の頭部は化粧カバー(12)の円弧外周面から沈没する埋め込み状態にあり、これを抜き出すことによって、上記化粧カバー(12)を別異の着色カラーが与えられたそれと交換することも可能である。The head of the fixing screw (25) is in an embedded state sinking from the outer peripheral surface of the arc of the decorative cover (12), and by pulling out the head, the decorative cover (12) is given a different colored color. It is also possible to exchange.
更に、(26)は上記芯棒(11)の張り出し先端部と対応位置する化粧カバー(12)の一端部において、その差込み溝(23)のフラットな溝底面から若干深く陥没された凹段面であり、上記芯棒(11)の対応的な円弧凸曲片(21)と嵌合することによって、その化粧カバー(12)が芯棒(11)の長手方向に沿い抜け出すおそれを防ぐ。Further, (26) is a concave step surface that is slightly deeply recessed from the flat groove bottom surface of the insertion groove (23) at one end portion of the decorative cover (12) positioned corresponding to the protruding tip of the core rod (11). By fitting with the corresponding arc-shaped curved piece (21) of the core rod (11), the decorative cover (12) is prevented from coming out along the longitudinal direction of the core rod (11).
本発明の上記レバーハンドル(A)を屋内の扉(D)へ取り付け施工するに当っては、従来からの常法に従って、その扉(D)のラッチボルト出没機構(図示省略)を構成するラッチ操作軸(ハンドルカム軸)(17)の両端部へ、図10〜12のように内外方向から一対のレバーハンドル(A)における取付ブラケット(B)の軸穴(16)を差し込み固定し、そのレバーハンドル(A)の握りバー(G)を回動操作すれば、ラッチボルト(図示省略)が扉(D)の木口面(フロント板)から没入する関係状態となるように組み立てれば良い。When the lever handle (A) of the present invention is attached to the indoor door (D), the latch that constitutes the latch bolt retracting mechanism (not shown) of the door (D) according to a conventional method. The shaft holes (16) of the mounting bracket (B) in the pair of lever handles (A) are inserted and fixed to both ends of the operation shaft (handle cam shaft) (17) from the inside and outside as shown in FIGS. As long as the grip bar (G) of the lever handle (A) is rotated, the latch bolt (not shown) may be assembled so as to be in a relational state where the latch bolt (not shown) is immersed from the wooden face (front plate) of the door (D).
本発明のレバーハンドル(A)では上記構成のように、握りバー(G)の芯棒(11)が取付ブラケット(B)と連続一体の金属製品として、その芯棒(11)にはシルバーメタリック調又はゴールドメタリック調の光反射面(22a)(22b)(22c)が設けられている一方、その芯棒(11)の光反射面(22a)(22b)(22c)を被覆する化粧カバー(12)が、着色顔料を含有する透明又は半透明の合成樹脂から、凸レンズとして機能し得る丸棒状に造形されているため、その握りバー(G)へ使用中に当る光の方角や、これを見る方角によって、上記化粧カバー(12)における着色カラーの濃淡度又明暗度が自づと変化し、言わば動的な装飾効果を得られることになる。In the lever handle (A) of the present invention, as described above, the core bar (11) of the grip bar (G) is a metal product continuously integrated with the mounting bracket (B), and the core bar (11) has a silver metallic tone. Alternatively, a decorative cover (12) covering the light reflecting surfaces (22a), (22b), and (22c) of the core rod (11), while the gold metallic light reflecting surfaces (22a), (22b), and (22c) are provided. ) Is formed from a transparent or translucent synthetic resin containing a colored pigment into a round bar shape that can function as a convex lens, so that the direction of light hitting the grip bar (G) during use and see this Depending on the direction, the shade or brightness of the colored color in the decorative cover (12) changes by itself, so that a dynamic decorative effect can be obtained.
つまり、握りバー(G)の化粧カバー(12)を透過して、芯棒(11)の光反射面(22a)(22b)(22c)に入射する光が、その光反射面(22a)(22b)(22c)による内部からの光反射作用を受けるため、化粧カバー(12)の着色カラーが淡く(明るく)鮮やかに照り出したり、逆に濃く(暗く)曇った状態に反映したり、その芯棒(11)と化粧カバー(12)との濃淡差(明暗差)がある所謂ツートンの階調状態になったり、更に入射光の方角如何では芯棒(11)と化粧カバー(12)とが同じ濃淡度(明暗度)として、その芯棒(11)の見えない隠蔽状態になったりすることさえ起るのであり、化粧カバー(12)が凸レンズとして働くこととも相俟ち、興趣変化に富む動的な装飾効果を演出することができる。That is, light that passes through the decorative cover (12) of the grip bar (G) and enters the light reflecting surfaces (22a), (22b), and (22c) of the core rod (11) is reflected on the light reflecting surfaces (22a) ( 22b) Because of the light reflection effect from the inside due to (22c), the colored color of the decorative cover (12) shines lightly (brightly) vividly, or conversely reflects in the dark (darkly) cloudy state, There is a so-called two-tone gradation state in which there is a difference in contrast (brightness / darkness) between the core rod (11) and the decorative cover (12), and depending on the direction of incident light, the core rod (11) and the decorative cover (12) May have a concealed state in which the core rod (11) cannot be seen with the same lightness (intensity), and the cosmetic cover (12) works as a convex lens. It is possible to produce a rich dynamic decoration effect That.
