Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
[0001] The present invention relates generally to an electric bed
and more particularly, to an electric bed package.
2. Description of the Related Art
[0002] A conventional electric bed generally has considerable
volume and weight as well as a relatively longer length. As a
result, it is inconvenience and not cost-effective to transport the
conventional electric bed, especially when the bed is shipped with
a bouffant mattress having bulky volume. To solve the aforesaid
problem, various foldable or dismantlable electric bedsteads, which
have reduced volume to facilitate transportation, are developed and
commercially available. However, no matter that the mattress and
the bedstead are combinedly or individually packed, the package of
current design still occupies a certain volume, resulting in that
the usage efficiency of the space of the cargo container is not
optimized. Therefore, a technical issue of reducing volume of the
electric bed package so as to enhance the usage efficiency of the
space of the cargo container and/or to increase convenience of
transportation needs to be solved by manufacturers and
practitioners in this industry field.
SUMMARY OF THE INVENTION
[0003] The present invention has been accomplished in view of the
above-noted circumstances. It is an objective of the present
invention to provide an electric bed package, which has a reduced
volume so as to enhance the usage efficiency of the space of the
cargo container for accommodating a plurality of the packages
and/or to increase convenience of transportation thereof.
[0004] To attain the above objective, the present invention
provides an electric bed package comprising a bedstead and a
packing member. The bedstead includes an upper body supporting
unit, a lower body supporting unit and a buttock supporting unit,
which all have a flat shape. The upper and lower body supporting
units are parallel stacked in a way that the buttock supporting
unit is arranged by a lateral side of a stack of the upper and
lower body supporting units and the buttock supporting unit is
substantially perpendicular to the upper body supporting unit. The
packing member packs and retains the bedstead therein. As such, the
electric bed package has a reduced volume, thereby enhancing the
usage efficiency of the space of the cargo container for
accommodating a plurality of the packages, reducing the
transporting cost, and increasing the convenience of transportation
thereof.

DETAILED DESCRIPTION OF THE INVENTION
[0012] The structure and technical features of the present
invention will be detailedly described hereunder by three
embodiments and accompany drawings. As shown in FIG. 4, an electric
bed package 1 provided in accordance with a first embodiment of the
present invention is composed of a bedstead 10, a mattress 60, and
a packing member 70. The bedstead 10 is composed of an upper body
supporting unit 20, a lower body supporting unit 30 and a buttock
supporting unit 40.
[0013] In FIG. 4, the bedstead 10 of the package 1 is shown in a
stacked manner. For better understanding the structure of the
bedstead 10, FIGS. 1-3 show the detailed structure of the bedstead
10 of the first embodiment. As shown in FIG. 1, the mattress 60 is
to be placed on the bedstead 10.
[0014] The upper body supporting unit 20 includes a front base 22,
a back supporting rack 23 provided with a rear side pivotally
connected with the front base 22, and a front actuator 24 having
two ends pivotally connected with the front base 22 and the back
supporting rack 23, respectively. The front base 22 has a rear
section 25 pivotally connected with the back supporting rack 23. As
such, the front actuator 24 can drive the back supporting rack 23
to swing between a horizontal position as shown in FIG. 1 and an
inclined position as shown in FIG. 2. It is to be noted that the
so-called front direction mentioned in the present invention is
directed to the left direction of FIG. 1, and the so-called rear
direction is directed to the right direction of FIG. 1. When the
back supporting rack 23 stays at the horizontal position, the upper
body supporting unit 20 is shaped like a flat member having a first
outer surface S1 facing upward, and a first inner surface S2, which
is opposite to the first outer surface S1 and faces downward. It is
to be especially mentioned that the first outer surface S1 is
mainly formed by the top surface of the back supporting rack 23 and
the top surface of the rear section 25 of the front base 22 and the
first outer surface S1 is approximately located on a same plane.
The first inner surface S2 is mainly formed by the bottom surface
of the front base 22 and the first inner surface S2 is
approximately located on a same plane. Further, a front portion of
the front base 22 is optionally equipped with two support legs 29
so as to raise the height of the bedstead 10.
[0015] The lower body supporting unit 30 includes a rear base 32, a
thigh supporting rack 33 provided with a front side pivotally
connected with the rear base 32, a lower leg supporting rack 34
having a front side pivotally connected with a rear side of the
thigh supporting rack 33, a rear actuator 35 having two ends
pivotally connected with the rear base 32 and the thigh supporting
rack 33, respectively, and a link 36 having two ends pivotally
connected with the rear base 32 and the lower leg supporting rack
34. The rear base 32 has a front section 37 pivotally connected
with the thigh supporting rack 33. As such, the rear actuator 35
can drive the thigh supporting rack 33 to swing between a
horizontal position as shown in FIG. 1 and an inclined position as
shown in FIG. 2. During the process of swinging the thigh
supporting rack 33 from the horizontal position to the inclined
position, the lower leg supporting rack 34 will also swing from a
horizontal position as shown in FIG. 1 to a lifted position as
shown in FIG. 2. When the thigh supporting rack 33 and the lower
leg supporting rack 34 both stay at the horizontal positions
thereof, the lower body supporting unit 30 is shaped like a flat
member having a second outer surface S3 facing upward, and a second
inner surface S4, which is opposite to the second outer surface S3
and faces downward. The second out surface S3 is mainly formed by
the opt surface of the front section 37 of the rear base 32, the
top surface of the thigh supporting rack 33 and the top surface of
the lower leg supporting rack 34, and the second outer surface S3
is approximately located on the same plane. The second inner
surface S4 is mainly formed by the bottom surface of the rear base
32 and the second inner surface S4 is approximately located on a
same plane. Further, a rear portion of the rear base 32 is
optionally equipped with two support legs 39 so as to raise the
height of the bedstead 10.
[0016] The buttock supporting unit 40 includes two middle bases 41,
and a buttock supporting rack 50 detachably and transversely
disposed on the two middle bases 41. Each middle base 41 has a
front end 42 detachably connected with the front base 22, and a
rear end 43 detachably connected with the rear base 32. The
connecting ways among the middle bases 41, the front base 22 and
the rear base 32 may vary and have many modifications. In this
embodiment, four connecting members 46 are transversely inserted
through one of the two middle bases 41 and threaded with the front
base 22 and the rear base 32 respectively, such that the middle
base 41, the front base 22 and the rear base 32 are connected
together. In this embodiment, the connecting members 46 are
realized as screws; however, in other embodiments, the connecting
members 46 may be realized as pins or other members having
connecting function. The amount of the connecting members 46 may
vary, and the connecting members 46 may be horizontally arranged or
vertically arranged. Further, each middle base 41 may be optionally
equipped with a support leg 48 so as to raise the height of the
bedstead 10.
[0017] The buttock supporting rack 50 has a flat shape with five
longitudinal rods 51 extending in the front-and-rear direction and
two transverse rods 52 extending in the left-and-right direction.
Each transverse rod 52 has an outer lateral side E, and the two
lateral sides E of the two transverse rods 52 are opposite to each
other. Each middle base 41 includes a vertically extending limiting
wall 49 located by one of the longitudinal rods 51. The buttock
supporting rack 50 and the two middle bases 41 are connected by two
pins 54 in a way that each pin 54 penetrates through the limiting
wall 49 of one of the two middle bases 41 and associated
longitudinal rod 51. By means of pulling off the two pins 54, the
buttock supporting rack 50 can be separated from the two middle
bases 41. The way of dismantling and assembling the buttock
supporting rack 50 and the middle bases 41 can be conveniently
operated thanks to the pins 54.
[0018] With the above-described structural design, the upper body
supporting unit 20, the lower body supporting unit 30 and the
buttock supporting unit 40 can be conveniently dismantled from each
other by means of detaching the connecting members 46. Further, by
means of detaching the pins 54, the buttock supporting rack 50 can
be conveniently dismantled from the two middle bases 41.
Furthermore, the support legs 29, 39 and 48 are respectively
mounted to the front base 22, the rear base 32 and the middle bases
41 by screws, such that these support legs 29, 39 and 48 can be
conveniently and respectively dismantled from the front base 22,
the rear base 32 and the middle bases 41 by means of turning and
loosening these support legs 29, 39 and 48.
[0019] The mattress 60 is integrally made by foam material, such as
EVA sponge, in a foldable manner. In other embodiment, the mattress
60 includes a plurality of cushion bodies.
[0020] To pack the bedstead 10 and the mattress 60, the lower body
supporting unit 30 is parallel stacked on above the upper body
supporting unit 20 in a way that the first inner surface S2 of the
upper body supporting unit 20 faces the second inner surface S4 of
the lower body supporting unit, such that the first outer surface
S1 is opposite to the second outer surface S3, as shown in FIG. 4.
Thereafter, the buttock supporting rack 50 of the buttock
supporting unit 40 is vertically arranged by a lateral side of the
stack of the upper and lower body supporting units 20 and 30 in a
way that the buttock supporting rack 50 is perpendicular or
substantially perpendicular to the upper body supporting unit 20 or
the lower body supporting unit 30, and the two lateral sides E are
flush with the first outer surface S1 of the upper body supporting
unit 20 and the second outer surface S3 of the lower body
supporting unit 30 respectively, such that the upper body
supporting unit 20, the lower body supporting unit 30 and the
buttock supporting unit 40 approximately form a flat cube as a
whole. And then, the other members of the buttock supporting unit
40, such as the two middle bases 41, the connecting members 46 and
the pins 54, and the legs 29, 39 and 48 can be placed in between
hollows of the upper body supporting unit 20 and the lower body
supporting unit 30. In this way, the bedstead 10 can be flatly
stacked with a relatively smaller volume. Especially, after the
bedstead 10 is stacked, the longitudinal length of the bedstead 10,
i.e. the length of the bedstead 10 in the front-and-rear direction,
can be reduced to an extent that is less than a half of the
original length (the longitudinal length of the bedstead 10 when
the bedstead 10 extends). In this embodiment, the longitudinal
length of the stacked bedstead 10 is reduced to about 45% of the
original length of the extended bedstead 10. Thereafter, the
mattress 60 is folded in half and placed on above the lower body
supporting unit 30 in a way that the mattress 60 is attached on the
second outer surface S3. Because the mattress 60 can be compressed
by an external force to deform, the length of the folded and/or
compressed mattress 60 is about equal to the length of the stack of
the bedstead 10. As such, the folded and/or compressed mattress 60
and the stack of the bedstead 10 can be concurrently placed in a
flat box, i.e. the packing member 70 in this embodiment. In other
words, the packing member 70 packs and retains the bedstead 10 and
the mattress 60 therein.
[0021] With the above-disclosed structural design, the electric bed
package 1 may have a reduced volume, thereby enhancing the usage
efficiency of the space of the cargo container for accommodating a
plurality of the packages and reducing the transportation cost. In
particular, the length of the package 1 of the present invention is
reduced to less than a half of the original length of the extended
bedstead 10, which breaks through the limitation that the length of
the conventional package is about or more than a half of the
original length of the extended bedstead, so that the volume of the
package 1 is more in line with the requirement of mailing, air
freight or ocean shipment, thereby reducing the transportation
costs so as to achieve the objective of the present invention.
[0022] In other embodiments, the mattress 60 may be placed under
the upper body supporting unit 20 and abutted against the first
outer surface S1 of the upper body supporting unit 20. Further, a
rope, belt, beg or other feasible member that can pack and retain
the bedstead 10 and the mattress 60 may be used as the packing
member 70 of the present invention in other embodiments.
[0023] It is to be noted that the electric bed package 1 of the
present invention may comprise the bedstead 10 only in other
embodiments. That is, the mattress 60 may be omitted in the
electric bed package 1.
[0024] Based on the technical features of the present invention,
various modifications to the structure of the electric bed package
1 of the present invention may be made. For example, the upper body
supporting unit 20 and the lower body supporting units 30 may be
respectively placed upside down and/or flipped left to right, or
the upper body supporting unit 20 and the lower body supporting
units 30 may exchange their positions, i.e. the upper body
supporting unit 20 is stacked on above the lower body supporting
unit 30. In any event, when the upper body supporting unit 20 and
the lower body supporting unit 30 are overlappingly stacked
together, the upper body supporting unit 20 and the lower body
supporting unit 30 are arranged in a way that the first inner
surface and the second inner surface are abutted with or face to
each other and the first outer surface and the second surface are
opposite to each other. For example, FIG. 5 shows an electric bed
package 1a provided in accordance with a second embodiment of the
present invention, which has a structure basically same as the
structure of the electric bed package 1 of the first embodiment,
except that the upper body supporting unit 20 is arranged upside
down and stacked on above the lower body supporting unit 30. In
this embodiment, the top surface of the upper body supporting unit
20 is regarded as the first outer surface S1' and the bottom
surface is the first inner surface S2'. Similarly, the bottom
surface of the lower body supporting unit 30 is regarded as the
second outer surface S3' and the top surface of the lower body
supporting unit 30 is the second inner surface S4'. The two lateral
sides E of the buttock supporting rack 50 are flush with the first
outer surface S1' and the second outer surface S3', respectively.
No matter how the orientations and positions of the upper body
supporting unit 20 and the lower body supporting unit 30 are
changed, they should fall within the scope the claims of the
present invention.
[0025] FIG. 6 shows an electric bed package 1b provided in
accordance with a third embodiment of the present invention, which
has a structure basically same as the structure of the electric bed
package 1 of the first embodiment, except that the electric bed
package 1b further comprises a sealing beg 80. After the mattress
60 is folded and received in the sealing beg 80, the air contained
in the sealing beg 80 is expelled out by vacuum cleaner or other
ways, such that the air pressure inside the sealing beg becomes
less than one standard atmosphere (1 atm), thereby reducing the
volume of the mattress 60. In particular, the longitudinal length
of the mattress 60 is reduced to an extent that is about less than
or equal to the longitudinal length of the upper body supporting
unit 20 or the longitudinal length of the lower body supporting
unit 30, such that the folded mattress 60 can be sandwiched between
the upper and lower body supporting units 20 and 30. In this way,
the mattress 60 is abutted against the first inner surface S2 of
the upper body supporting unit 20 and the second inner surface S4
of the lower body supporting unit 30.
[0026] Another differentiated feature lies in that the longitudinal
length of the buttock supporting rack 50 in this embodiment is
greater than that of the first embodiment, and the longitudinal
lengths of the upper and lower body supporting units 20 and 30 are
less than those of the first embodiment. As such, the total length
of the whole package can be reduced to less than 40% of the
original length of the extended bedstead 10. Though the thickness
of the package increases, the size of the package in this
embodiment more fulfills with the transportation specification in
other conditions.
[0027] It is to be further mentioned that the structures of the
upper body supporting unit 20, the lower body supporting unit 30
and the buttock supporting unit 40 are not limited to the
above-disclosed embodiments. Various modifications to the
structures of the aforesaid units 20, 30 and 40 may be made. For
example, the upper body supporting unit 20 may further comprise a
head supporting rack pivotally connected with the back supporting
rack 23 with an actuator for driving the head supporting rack to
swing. That is, no matter how the structures of the upper body
supporting unit 20, the lower body supporting unit 30 and the
buttock supporting unit 40 are modified, they should fall within
the scope of the claims of the present invention as long as the
upper body supporting unit 20, the lower body supporting unit 30
and the buttock supporting unit 40 are arranged in a flat-shaped
manner when they are packed. Further, in other embodiments, the
buttock supporting rack 50 may be arranged in a way that the two
lateral sides E of the buttock supporting unit 50 are not flush
with the first outer surface S1 or S1' and the second outer surface
S3 or S3', respectively.
[0028] The invention being thus described, it will be obvious that
the same may be varied in many ways. Such variations are not to be
regarded as a departure from the spirit and scope of the invention,
and all such modifications as would be obvious to one skilled in
the art are intended to be included within the scope of the
following claims.
