Description
【０００１】[0001]
この考案は、自動車用のホイールカバーに関し、とくにその取付け機構に係る ものである。 The present invention relates to an automobile wheel cover, and particularly to a mounting mechanism thereof.
【０００２】[0002]
従来、この種の技術として、自動車のディスクホイールにホイールカバーを係 止させるに当たり、ホイールカバー本体の裏面周囲に設けた係止リブに、ワイヤ ーからなる環状体を内側から取り付けて、この係止リブを外側に弾力的に張り出 したり、この係止リブを外側に弾力的に張り出したり、さらにまたこの環状体の 一部を湾曲させて予圧（バイアスプレシュアー）を与えるようにしていた。また 一方、外側係止リブと内側係止リブの間に、Ｕ字状の板ばねなどを挿入して、こ のばね圧を調整することにより、ホイールカバーをディスクホイールに保持させ るようにした考案が本件出願人により提案されている（実願昭60-66209号）。 Conventionally, as a technique of this kind, when locking a wheel cover to an automobile disc wheel, an annular body made of a wire is attached from the inside to a locking rib provided around the back surface of the wheel cover body, and this locking is performed. The ribs are elastically extended to the outside, the locking ribs are elastically extended to the outside, and a part of the annular body is curved to give a preload (bias pressure). On the other hand, by inserting a U-shaped leaf spring or the like between the outer locking rib and the inner locking rib and adjusting the spring pressure, the wheel cover is held by the disc wheel. A device has been proposed by the applicant (Japanese Utility Model Application No. 60-66209).
【０００３】[0003]
内、外側係止リブの材料（合成樹脂材）の劣化による係止不良状態の早期に おける発生、ワイヤーによる環状体、板ばねのばね圧の劣化および適度のばね圧 の調整を得ることの難しさが問題点となり、加えてそれらばね材の製作費の高価 なことも原因となって、常に一定の圧力でホイールカバーをホイールディスクに 係止、脱着させるための良策が、解決を待つ課題として指摘されていた。 Occurrence of defective locking at an early stage due to deterioration of the material of the inner and outer locking ribs (synthetic resin material), deterioration of spring pressure of the annular body and leaf spring by the wire, and difficulty in obtaining appropriate spring pressure adjustment. However, due to the high manufacturing cost of these spring materials, a good measure to lock and remove the wheel cover on the wheel disc at a constant pressure is a challenge that needs to be resolved. It was pointed out.
【０００４】[0004]
この考案は、合成樹脂製ホイールカバーの内、外側係止リブ間に、常に一定の 予圧を付与するような構成を採用したものである。すなわち合成樹脂製ホイール カバー本体の裏面周囲に一体成形して設けた、内、外側係止リブの間に、Ｕ字状 の板ばねの一片を他片に弾力を付勢するように係止させたスプリングを挿入し、 ホイールディスクに係止するための予圧を付勢したことを特徴とする予圧機構を 有するホイールカバーである。 This invention employs a structure in which a constant preload is always applied between the outer locking ribs of the synthetic resin wheel cover. That is, one piece of a U-shaped leaf spring is locked between the inner and outer locking ribs integrally formed around the rear surface of the wheel cover body made of synthetic resin so as to bias the other piece. A wheel cover having a preload mechanism characterized in that a preload for biasing the wheel disc is inserted by inserting a spring.

ホイールカバーの裏面周囲に内、外側係止リブを一体成形し、これらの内、外 側係止アーム間に、Ｕ字状の板ばねの一片を他片に弾力を付勢するように係止さ せたズプリングを挿入することによって、この内、外側係止リブ間に予圧を付与 し、このホイールカバーをホイールディスクに取り付けるに当たり、ホイールデ ィスクのハンプ部にこれらの係止リブを挿入時、スプリングを押圧して内、外側 係止リブはその間隔を縮小して弾力的にホイールカバーのハンプ部に圧接されて 挿入され、挿入後、スプリングが拡がって内、外側係止リブ間に予圧状態を保持 し、外脱時には前記したのと同様の作動によってハンプ部を外れ、再び一定の予 圧状態となる。 Inner and outer locking ribs are integrally molded around the back surface of the wheel cover, and one of the U-shaped leaf springs is locked between these inner and outer locking arms so as to urge the other to elastically. A preload is applied between the inner and outer locking ribs by inserting the inserted springs, and when mounting this wheel cover on the wheel disc, when inserting these locking ribs on the hump part of the wheel disc, The inner and outer locking ribs are pressed into the hump part of the wheel cover and inserted elastically by reducing the gap between them, and after insertion, the spring expands and preloads between the inner and outer locking ribs. The hump part is held by the same operation as described above when it is pulled out, and a constant preload state is restored.

図１に示すのは、合成樹脂製ホイールカバー(H) 裏面周囲、数箇所において、 内側係止リブ(1) と外側係止リブ(2),(2')とが一体成形されており、これら内側 、外側係止リブ(1),(2),(2')間に図２（ａ) 、（ｂ）に示す予圧を付与するスプ リング(4) を挿着する。それはＵ字状の板ばね材の一片(e) の開放端、中央部分 より突出片(f) を形成し、これを折り曲げて他片(g) に係合させ、これら両方の 突出片(f) 、他片(g) 間に弾力を付勢したもので、これを図１に示す内、外側係 止リブ(1),(2),(2')間に挿入することによって、このスプリング(4) の有する予 圧によって、内、外側係止リブ(1),(2),(2')間に予圧状態を保持することができ るものである［図２（ｂ），図３参照］。 As shown in FIG. 1, the inner locking rib (1) and the outer locking ribs (2), (2 ') are integrally formed around the back surface of the synthetic resin wheel cover (H) at several places. A spring (4) for applying a preload shown in FIGS. 2 (a) and 2 (b) is inserted between the inner and outer locking ribs (1), (2), (2 '). It forms a protruding piece (f) from the open end and the central part of one piece (e) of U-shaped leaf spring, bends this and engages with the other piece (g), and both of these protruding pieces (f ), An elastic force is applied between the other pieces (g), and this spring is inserted between the outer retaining ribs (1), (2), (2 ') shown in FIG. By the preload of (4), the preload state can be maintained between the inner and outer locking ribs (1), (2), (2 ') [Fig. 2 (b), Fig. 3]. reference].
【０００７】 すなわち内、外側係止リブ(1),(2),(2')間にこのスプリング(4) を挿着するこ とによって、スプリング(4) は常時は一定の開き具合を保っているが、外側から の力を受けることによって、その弾力により内方に向かってその幅を縮小し、そ の外側からの力が無くなることによって、前述の一定の幅に戻る。このように常 に一定幅を保ち、外力に応じてその幅を縮小、拡大する作用を営むため、これを 内、外側係止リブ(1),(2),(2')間に挿入してあることによって、ホイールカバー (H) をディスクホイール(D) のハンプ部(d) に押し込む際に［図３参照］、外側 係止リブ(2) が内方に押され、そのときにスプリング(4) のばね圧に抗して挿入 され、ついでハンプ部(d) 内に拡がってホイールディスク(D) に完全に係止する ことになる。そして外脱時にはスプリング(4) のばね圧に抗して外側係止リブは 内方に入り、ハンプ部(d) より外れ、その後、内、外側係止リブ(1),(2),(2')間 には、またこのスプリング(4) の予圧が働く状態となる。That is, by inserting this spring (4) between the inner and outer locking ribs (1), (2), (2 '), the spring (4) always keeps a certain opening degree. However, when it receives a force from the outside, its elasticity reduces its width toward the inside, and when the force from the outside disappears, it returns to the aforementioned constant width. In this way, a constant width is always maintained, and the width is reduced and expanded according to the external force.Therefore, this is inserted between the inner and outer locking ribs (1), (2), (2 '). This ensures that when the wheel cover (H) is pushed into the hump (d) of the disc wheel (D) [see Fig. 3], the outer locking ribs (2) are pushed inward and the spring It is inserted against the spring pressure of (4), then spreads into the hump (d) and is completely locked to the wheel disc (D). Then, at the time of detaching from the outside, the outer locking rib enters inward against the spring pressure of the spring (4) and disengages from the hump (d). Between 2 '), the preload of this spring (4) is activated again.

この考案は、合成樹脂製ホイールカバー本体の裏面周囲に一体成形して設けた 内、外側係止リブ間に、常に一定の適度の予圧があるため、これによってホイー ルディスク側の係止箇所において、寸法のばらつきがあっても、挿着または外脱 時において、それを最大限に吸収でき得るものであり、また一方、ばね常数の少 ないばねを使用しても、予圧を働かすことにより、大きな係止力を得ることが可 能となるものである。なおこのような、予圧を働かさない場合には、合成樹脂材 で一体成形された係止リブには、常時、加圧力がかかり、それらを早期に劣化さ せることとなるが、この考案はそのような虞を解消するものである。なおまた、 従来のこの種のホイールカバーに用いられていた、環状体によるばね材などを不 要とすることによって、コスト減となる長所も大きい。 In this invention, there is always a certain amount of preload between the inner and outer locking ribs, which are integrally molded around the back surface of the wheel cover body made of synthetic resin, so that at the locking location on the wheel disc side. Even if there is a variation in dimensions, it can be absorbed to the maximum during insertion or removal, and on the other hand, even if a spring with a small number of spring constants is used, the preload works It is possible to obtain a large locking force. When such a preload is not applied, the locking rib integrally formed of the synthetic resin material is always subjected to a pressing force, which deteriorates them at an early stage. This is to eliminate such a fear. Further, since the spring member made of an annular body, which is used in the conventional wheel cover of this type, is not required, there is a great advantage that the cost is reduced.
