SIMPLE LEAF-TYPE FOLDING FRAME
Abstract
A simple leaf-type folding frame is bent into a fully U-shaped
lamella. A slot is formed between the front-side lamella and
rear-side lamella, where a lamella, such as a perpetual calendar
card, a photo, a product label or the like, may be inserted for
combination. Especially, the rear-side lamella is cut to form at
least one pair of inner and outer cut grooves that are symmetrical
to each other. The inner cut groove is formed in the coverage of
outer cut groove. Thus, the inner cut groove may be used to pull
half a cut joint flake so that the joint flake may be turned and
folded in a reverse direction to sustain a sidewall of the
rear-side lamella, thereby a 3D folding frame being formed.

Description
BACKGROUND OF THE INVENTION
[0001] (a) Field of the Invention
[0002] This invention relates to a folding frame and particularly
to a simple leaf-type folding frame.
[0003] (b) Description of the Prior Art
[0004] A conventional frame that, for example, is used for a photo,
a perpetual calendar, a product label, a post-and-rank card and the
like is a frame base that is generally made of a rigid acryl and
structured with a slant stand side and a bottom side that may be
placed the basal plane of a table. Alternatively, another
conventional frame base is formed with a support foldable that is
pulled up for achievement of a standing frame. It costs very much
to manufacture the conventional frames mentioned above, and the
frame provided with a standing support easily topples because not
standing securely.
[0005] Consequently, because of the technical defects of described
above, the applicant keeps on carving unflaggingly through
wholehearted experience and research to develop the present
invention, which can effectively improve the defects described
above.
SUMMARY OF THE INVENTION
[0006] This invention is mainly to provide a simple leaf-type
folding frame that is bent into a U-shaped structure. Inner and
outer cut grooves on a rear-side flake are used for reverse folding
and orientation, and then a 3D folding frame may be fast formed
where a random-shaped lamella, such as a perpetual calendar card, a
photo, a product label or the like, may be inserted for
combination. The whole structure is very simple and light, thin in
physical volume before being unfolded, it is extremely easy to use
and pack or collect the frame, the frame stands securely after
being unfolded, and the cost of manufacturing is very low.
[0007] This invention is further to provide the simple leaf-type
folding frame of which the inner and outer cut grooves are formed
with two ends, each of which is formed with a long strip of
aperture, such as a long oval-shaped aperture, which communicates
with a cut groove. Thus, when the joint flake is turned out, the
end may be prevented from splitting for assurance of the joint
flake that cannot crack and be broken after turning up.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0015] Now, the present invention will be described more
specifically with reference to the following embodiments. It is to
be noted that the following descriptions of preferred embodiments
of this invention are presented herein for purpose of illustration
and description only; it is not intended to be exhaustive or to be
limited to the precise form disclosed.
[0016] As shown in FIG. 1, a simple leaf-type folding frame
according to this invention is formed with a U-shaped lamina 1
having a front-side lamina 11 and a rear-side lamina 12. A slot 13
of which the gap is adequate is formed between the front-side
lamella 11 and rear-side lamella 12 of the U-shaped lamella 1. The
rear-side lamella 12 is cut to form at least one pair of inner and
outer cut grooves 121 and 122 that are symmetrical to each other.
The inner and outer cut grooves 121 and 122 are distributed to
match with each other. The inner cut groove 121 is formed in the
coverage of outer cut groove 122 and thus the inner and outer cut
grooves 121 and 122 are formed. Thus, the inner cut groove 121 may
be used to pull half a cut joint flake 123 so that the joint flake
123 may be turned and folded in a reverse direction to sustain a
sidewall 124 of the rear-side lamella 12, as shown in FIG. 2, or
flexibly support a lamella inserted into the slot 13; the lamella
may be flexibly supported by means of the two pairs of turned and
folded joint flake 123 for fear of falling. Accordingly, a 3D
folding frame is formed that may be unfolded to stand securely and
balance, as shown in FIG. 3.
[0017] The inner and outer cut grooves 121 and 122 may be
distributed in U shape that correspond to each other so that the
inner cut groove 121 may be used to pull outwards half the cut
joint flake 123. Alternatively, the inner and outer cut grooves 121
and 122 may be various in shape, if any, but half the cut joint
flake 123 may be pulled outwards. After the joint flake 123 is
turned out, a 3D support portion 125 is formed so that the support
portion 125 may help the folding frame stand.
[0018] A long strip of aperture A, such as a long oval-shaped
aperture as shown in the figure, which communicates with each other
are formed at the two ends of inner and outer cut grooves 121 and
122, so when being turned up, the joint flake 123 may be prevented
from suddenly splitting open that is caused by the turn-up of the
end for assurance of the integrity of joint flake 123, after being
turned up, and for prevention of the joint flake 123 from cracking
and splitting.
[0019] The slot 13 between the front-side lamella 11 and rear-side
lamella 12 is formed where a lamella, such as a perpetual calendar
card, a photo, a product label or the like, may be inserted for
combination so that the 3D folding frame may be used as a random
frame without any limitation. Further, at least one end 14 of the
U-shaped lamella 1 is bent, or alternatively in the figure
illustrating the embodiment, the other end 15 is also bent to make
a random lamella to be inserted securely.
[0020] Surely, depending on the requirements of use, the
advertisement, trademark, symbol, character, or a random pattern
may be further printed or transferred on a determined site of
surface of the front-side lamella 11 for achievement of various
demonstrations. Likewise, on the surface of rear-side lamella 12,
an advertisement character, a trademark, a symbol, or a pattern may
be printed.
[0021] In this invention, the U-shaped lamella 1 is not limited in
the aspects of shape, size, and color; the shape of frame may be
common rectangle and may also be round, oval, polygonal, or
regularly or irregularly shaped, which may fully be replaced.
[0022] In an embodiment shown in FIGS. 5 and 6 that illustrates a
single pair of inner and outer cut grooves 121 and 122, the
rear-side flake 12 of U-shaped lamella 1 is formed with only one
single pair of inner and outer cut grooves 121 and 122 that are
symmetrical to each other and the inner and outer cut grooves 121
and 122 thus match with each other; further, the inner cut groove
121 is formed in the coverage of outer cut groove 122 so that the
inner cut groove 121 may be used to pull half a single joint flake
123 and may be turned and folded in a reverse direction for
clamping, as shown in FIG. 6, and may be likewise unfolded to bring
a 3D folding frame that may stand securely and balance.
[0023] The fully bent U-shaped lamella 1 is generally made of
plastics and is preferably transparent in a color or no color. The
front-side lamella 11 of U-shaped lamella 1 may be formed into a
sealed surface or a surface on which one or more determined
apertures 111, as shown in FIG. 7, for achievement of various
requirements. For example, FIG. 7 illustrates the combination of a
perpetual calendar, in which a plurality of apertures 111 are
formed on a determined site of the front-side lamella 11 of
U-shaped lamella 1 for insertion and combination of a lamella 2 on
which a perpetual calendar is printed. Each aperture 111 may be
corresponding to a site indicating Year, Month, Date, or Day on the
perpetual calendar to show correct time when the perpetual calendar
2 shifts.
[0024] While the invention has been described in terms of what is
presently considered to be the most practical and preferred
embodiments, it is to be understood that the invention needs not be
limited to the disclosed embodiment. On the contrary, it is
intended to cover various modifications and similar arrangements
included within the spirit and scope of the appended claims which
are to be accorded with the broadest interpretation so as to
encompass all such modifications and similar structures.
