【考案の詳細な説明】 〔産業上の利用分野〕 この考案は、軽金属やプラスチック等で押出し成形され
た額縁のフレームに関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a frame frame extruded from light metal, plastic, or the like.
軽金属製の額縁のフレームは、押出し加工によって比較
的自由な断面形状が得られることから、従来から額縁の
大小にかかわらず多用されており、その断面形状も様々
である。Since a frame of a light metal frame has a relatively free cross-sectional shape obtained by extrusion processing, it has been widely used regardless of the size of the frame, and the cross-sectional shape is also various.
しかし、基本的には、側壁の前端に板ガラスを止める前
面壁を有し、後端部に裏板を止めるための段部と、フレ
ームどうしの組み立てのための蟻溝とを有する形状とな
っている。However, basically, the front end of the side wall has a front wall for stopping the plate glass, and the rear end has a step portion for stopping the back plate and a dovetail groove for assembling the frames. There is.
第１図は、その最も基本的なフレームの一例を示したも

品を納める必要とか、裏板を止める掛止具の特殊性とか
の理由によって、裏板の掛止段部３から前端までの側壁
１の寸法Ｌを比較的長く形成してある。FIG. 1 shows an example of the most basic frame, but in order to make the picture frame look sharp, a front wall 2 having a relatively narrow width W is provided at the front end of the side wall 1, and Due to the interior relations, such as the need to store the work deeply by decoration such as mats, and the peculiarities of the hooks that stop the back plate, the size of the side wall 1 from the hook step 3 to the front end of the back plate. L is formed relatively long.
一方、主として額縁のデザインや機能上の必要性から、
種々の複雑な断面形状のフレームが用いられ、従来、そ
の中には、複雑な形状にしたために生じた余り部分を中
空に形成したものもあった。On the other hand, mainly because of the design and functional needs of the frame,
Frames having various complicated cross-sectional shapes have been used, and in the past, some of them have hollow portions formed due to the complicated shapes.
また、押出し形材においては、中空部を設けるとそれが
補強になることが知られていた。Further, it has been known that, in the extruded shape member, providing a hollow portion provides reinforcement.
従来、軽金属製の額縁のフレームは、このように中空部
を有していたとしても、それは設計上の余りとして形成
されたものであったから、中空部が補強となっても、そ
の位置が不適切であるために、補強的役割を十分に果た
し得なかった。Conventionally, a frame of a light metal frame has such a hollow portion, but since it is formed as a design excess, even if the hollow portion is reinforced, its position is not correct. Being adequate, it could not play a sufficient reinforcing role.
また、第１図に示すようなフレームにおいても、蟻溝４
にＬ字形の連結板を挿入することによって、縦横フレー

中心になるのであるが、組み立ての中心が不完全中空の
蟻溝であって、強度的安定性が確保し難いこと、また側
壁１が組み立ての中心から前端までの距離Ｌが長く、し
かもリブの作用を果たす前面壁２の巾Ｗも狭いことか
ら、殊に、大きいサイズの額縁を組み立てた場合には、
そのようなことからフレームが捩れたり撓だりして額縁
が歪み、延いては、湿気の影響で裏板が反ったり、ある
いは巾狭との関係もあって、板ガラスや裏板が見苦しく
外れた感じになる等の問題があった。Further, in the frame as shown in FIG. 1 also, the dovetail groove 4
By inserting the L-shaped connecting plate into the vertical and horizontal frames, the dovetail groove 4 becomes the center of the assembly, but the center of the assembly is an incomplete hollow dovetail. In particular, it is difficult to ensure strength stability, and the distance L from the center of the assembly to the front end of the side wall 1 is long, and the width W of the front wall 2 that acts as a rib is also narrow. If you assembled the picture frame,
As a result, the frame is twisted or flexed, the frame is distorted, and the back plate warps due to the influence of moisture, or the plate glass or back plate is unsightly removed due to the narrow width. There was a problem such as becoming.
この考案は、上記のような実情に鑑みて、基本的断面形
状であって、しかも裏板の掛止段部から前端までの側壁
の寸法が長く、前面壁の巾が狭いフレームであっても、
最適箇所に補強の中空部を最適形状に設けることによっ
て、捩れや撓みの発生しないようにすることを目的とし
たものである。In view of the above-mentioned circumstances, the present invention provides a frame having a basic cross-sectional shape, a long side wall from the hook step of the back plate to the front end, and a narrow front wall. ,
The purpose is to prevent the occurrence of twisting or bending by providing a reinforcing hollow portion in an optimum shape at an optimum position.
上記の目的を達成するためのこの考案の構成は、側壁の
後端近くに、蟻溝の底部壁と、一側部壁と、一方の掛止

端には前面壁を突設して形成した額縁のフレームにおい
て、側壁にはさらに蟻溝の底部壁よりも前方にその底部
壁と平行に補強壁を突設し、側壁の一部と、蟻溝の底部
壁と、前記補強壁と、蟻溝の側部壁の延長壁とからなる
中空部を前記掛止段部兼用として設けたことをその要旨
とするものである。In order to achieve the above object, the structure of the present invention is such that an inversion refraction wall consisting of a bottom wall of a dovetail groove, one side wall, and one hooking piece is provided near the rear end of the side wall, At the rear end, the other hooking piece is projected to form a rear opening type dovetail groove, the side wall from the hooking step of the back plate to the front end is made long, and the front wall is at the front end of the side wall. In the frame of the frame formed by projecting, a reinforcing wall is projected further in front of the bottom wall of the dovetail groove in parallel with the bottom wall of the dovetail groove, and a part of the side wall and the bottom wall of the dovetail groove are formed. The gist of the invention is to provide a hollow portion, which is composed of the reinforcing wall and an extension wall of the side wall of the dovetail groove, as the hanging step portion.
額縁のフレームを上記のように構成したから、これによ
り額縁を組み立てるときには、Ｌ字形の連結板を縦横フ
レームの蟻溝に挿入し、その切断端面を互に突き合わせ
て連結板を締め付ける。そうすると、連結板を介して、
組立ての中心が蟻溝の位置になることは従来のものと同
様であるが、蟻溝の前に丁度隣接して中空部を設けてあ
るため、その組立ての中心が直接的に補強される。Since the frame frame is configured as described above, when assembling the frame, the L-shaped connecting plates are inserted into the dovetail grooves of the vertical and horizontal frames, and the cut end faces thereof are butted against each other to tighten the connecting plates. Then, via the connecting plate,
Although the center of the assembly is located at the position of the dovetail, it is similar to the conventional one, but since the hollow portion is provided just in front of the dovetail, the center of the assembly is directly reinforced.
しかも、中空部は構成において蟻溝および側壁と共通部
分が多く、また蟻溝と同位置において平行状態に、且つ
同巾に形成されているため、補強効果が大きく、またバ
ランスの取れた補強となることから、捩れや撓みが容易
には発生しないものである。Moreover, since the hollow part has many common parts with the dovetail groove and the side wall in the configuration, and is formed in parallel with the dovetail groove at the same position and with the same width, a large reinforcing effect and a well-balanced reinforcement can be obtained. Therefore, twisting and bending do not easily occur.
次に、この考案を実施例の図面に基づいて説明する。 Next, this invention will be described with reference to the drawings of the embodiments.
図面は一実施例を示したもので、そのフレームＦは、ア
