不要再纠结为什么叫这么难理解的名字了。因为从golden arch直译过来的撒。金色的拱门。就叫金拱门咯。

"McDonald's logo" redirects here. For the sign, see McDonald's sign (Pine Bluff, Arkansas).The Golden Arches used on the exterior of the Times Square McDonald's restaurant.
The Golden Arches are the symbol of McDonald's, the global fast-food restaurant chain. Originally, real arches were part of the restaurant design. They were incorporated into the chain's logo in
1962, which resembled a stylized restaurant, and in the current Golden Arches logo, introduced 1968, resembling an "M" for "McDonald's".
In 1952, brothers Richard and Maurice McDonald decided they needed a new building to house their hamburger restaurant in San Bernardino, California. They wanted this building to have an entirely
new design which would achieve two goals: even greater efficiency, and an eye-catching appearance. They interviewed at least four architects altogether, finally choosing Stanley Clark Meston, an
architect practicing in nearby Fontana, in late 1952. The arches had a direct bearing on the interviewing process and their choice of Meston: the first architect they interviewed objected to the
arches the brothers wanted; a second wanted to change the arches; a third, prominent Los Angeles architect Douglas Honnold, said that if the brothers were going to tell him what to do they would be
better off doing it themselves.
Along with their practical knowledge, the brothers brought Meston a rough sketch of two half-circle arches drawn by Richard. The idea of an arch had struck Richard as a memorable shape to make
their stand more visible. After considering one arch parallel to the front of the building, he had sketched two half-circles on either side of the stand. Meston, together with his assistant Charles
Fish, responded with a design which included two 25-foot (7.6 m) yellow sheet-metal arches trimmed in neon, called "golden arches" even at the design stage. His design also included a third,
smaller arch sign at the roadside with a pudgy character in a chef's hat, known as Speedee, striding across the top, trimmed in animated neon.
According to architectural historian Alan Hess, "Meston and Fish turned the crude half-circle suggested by Richard McDonald's sketch into a tapered, sophisticated parabola, with tense, springing
lines conveying movement and energy." In the same article Hess added this footnote: "Who first suggested the parabola is unclear. Richard McDonald and George Dexter, the sign contractor who
fabricated the first arches, recalled that Dexter came up with the idea and added them to the plans. Charles Fish, who did the working drawings and aided Meston in the design, attributes the idea
to his familiarity with the form from a school project in which he used structural parabolas for a hangar. The form was one of many advanced engineering solutions, including folded plate roofs,
that were in common currency."
The first franchised outlet bearing Meston's design opened in May 1953 in Phoenix, Arizona. Subsequent franchisees of the McDonald brothers were also required to use Meston's design, although
Meston adapted the plans for each to the conditions and building codes of each site.
In 1962, seeking to upgrade its image, the company sought a new logo. Fred Turner sketched a stylized "V", but the company's head of engineering and design, Jim Schindler, extended the "V" into an
"M" resembling a McDonald's store viewed from an angle, with a red isosceles trapezoid "roof" serving as background for lettering.
While McDonald's dropped the physical arches from nearly all of its restaurants in the 1960s[citation needed], the Golden Arches have remained in the logo, and as a commonly understood term for the
company. This was partially due to Louis Cheskin's argument that the arches, which he likened to "mother McDonald's breasts", had "Freudian applications to the subconscious mind of the consumer and
were great assets in marketing McDonald's food." In Canada, all McDonald's stores and commercials have a maple leaf in the middle of the Golden Arches.
Alan Hess summarized the arch's origin in Googie architecture and ultimate significance as follows:
The arch was conceived by businessman Richard McDonald, an untrained designer with no knowledge of erudite architectural examples. His intent was pragmatic: to be noticed. This determined its
scale, position, and simple shape visible over long distances following the precedent of earlier drive-ins with which he was familiar. To McDonald, the arch was an arbitrary form, without symbolic
or historic associations, which he hoped would come to symbolize McDonald's. The arches' position implies no traditional use of the arch as an entry, nor are they structural. The architect
delineated this formal concept determined by the client in the energetic lines and machine-like surfaces of a popular commercial vernacular style current in the 1940s and 1950s ... Meston's design
proved successful as design and icon because of, not in spite of, its commercialism.
The term "Golden Arches" is sometimes used as metonym, symbolizing capitalism or globalization in phrases such as the "Golden Arches Theory of Conflict Prevention", since McDonald's is one of the
more prominent American corporations that have become global in their reach (along with Coca-Cola and Nike).
