Description
FIELD OF THE INVENTION
[0001] The present invention relates to an extendable and
expandable positioning structure of a trunk bag, and especially to
a retaining structure with a slidable buckling device for expanding
the length of the box.
BACKGROUND OF THE INVENTION
[0002] In travelling, many clothes are carried and some articles
are bought, and thus a small baggage becomes a large baggage.
Therefore, many packages are necessary. In a long traveling, this
is not convenient, moreover, as one goes to foreign.
[0003] Referring to FIGS. 12 to 14, a telescopic box is
illustrated. In that design, middle section 31 of an package 3 is
formed, which can be formed as a layer to be hidden. As the package
3 at the middle section 31 is unused, it can be hidden in the box.
And a zipper can be used to combine the lower end at the upper half
33 of the package 3 and the upper end of the lower half 34 of the
package 3 so as to be formed as a complete box.
[0004] The inner surface of the box is classified as a soft surface
and a hard surface. The soft surface has no inner liner. It is a
packaging structure by the package 3 with the zipper 32. However,
some box requires a preferred protection for placing objects with
weak structure, and thus, the extension of the structure must be
enhanced.
[0005] As shown in the figures, two sides of the package 3 each are
installed with an extending retaining structure 35 having a track
36 at the lower half of the lateral side. A sliding plate 37 is
connected to the track 36. The sliding plate 37 is moved upwards
and downwards at the lateral surface of the track 36. Since the
upper end of the sliding plate 37 is fixed to the lower end of the
upper half 33 of the package 3, and the track 36 is fixed near the
upper end of the lower half 34 of the package 3. The upper half and
lower half of the package 3 is a middle section 31 which serves to
provide space for expanding the box. Since the sliding 37 is hard,
a preferred bearing force can be generated at the lateral surface
of the box.
[0006] Since the upper end of the sliding plate 37 is connected to
an upper female sticky strip 38 and the lower and of the sliding
plate 37 is connected to a lower female sticky strip 39. Moreover,
since the lower half 31 of the package 3 is extended with a
connecting strip 30, and a male sticky strip 301 is connected to
the connecting strip 30. When the sliding plate 37 is motionless,
as shown in FIG. 13, the male sticky strip 301 will stick to the
lower female sticky strip 39 at a lower end of the sliding plate
37. When the sliding plate 37 moves upwards to an expansion
position, as shown in FIG. 14, the male sticky strip 301 is
connected to the upper female sticky strip at the upper end of the
sliding block 37.
[0007] The sliding plate 37 can be fixed to the upper frame 331.
The track 37 can be fixed to a lower frame 341. The upper frame 331
and the lower frame 341 are connected to the upper half 33 and
lower half 34 of the package 3. In the prior art structure, by the
sticky property between the upper and lower female sticky strips 38
and 39 and the sticky property of the male sticky strip 301, the
connecting strip 30 is positioned with respect to the sliding block
37.
[0008] Therefore, the extending retaining structure 35 can be
conveniently adjusted and positioned since the cover of the box
must be opened at first, and the objects at two sides of the box
must be removed, then the sticky strips 39 and 301 at the lower
side of the sliding plate 37, and then the package 3 is lifted, so
that the sliding plate moves upwards. Then, the male sticky strip
301 is adhered to the sticky strips 38 and 301 at the upper
position of the sliding block 37 so as to be positioned in a new
position. Thus, the package 3 may be used in a large volume.
[0009] However, each time the box must be opened, and thus the
operation is inconvenient. Furthermore, if after positioning, if
the box is extruded, the sliding plate and the track are possible
compressed and deformed so as to lose of affect.
SUMMARY OF THE INVENTION
[0010] Accordingly, the primary object of the present invention is
to provide an extendable and expandable positioning structure of a
trunk bag, wherein the volume of the box can be expanded while the
cover is unnecessary to be opened. When a heavy pressure is applied
on the present invention, it will release automatically so that the
slidable buckling device will not be destroyed. Furthermore, the
transferring and stacking of a trunk are performed conveniently.
Since the buckling device can be adjusted preferably, the space of
the box can be adjusted easily. It is only needed to match the bag
receiving portion of the bag, the bag can be adjusted to be thicker
or thinner. Since a box frame is added so that resistance of the
box is increased.
[0011] To achieve above objects, the present invention provides a
extendable and expandable positioning structure of a trunk bag
comprising a bag body and a movable buckling device at two sides of
the bag. The bag body is divided into a bag receiving portion at
the middle section thereof. The bag receiving portion has an upper
bag at the upper side thereof and a lower bag at the lower side
thereof. An inner side of the upper bag is connected to an upper
box frame. The lower box frame is connected to a retaining plate
and the retaining plate is installed with at least one long groove.
The long groove is installed with at least one positioning female
element. The upper bag is connected to the sliding block. The
sliding block is installed with a positioning male element at
position with respect to the positioning female element so that the
positioning male element is capable to be buckled to the
positioning female element. The thickness of the sliding block
extends out of the long groove and two outer edges of the sliding
block being engaged with the surface of the retaining plate so that
as the bag body is pulled upwards, the sliding block is driven to
be moved in the long groove.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0027] Referring to FIGS. 1 to 11, three embodiments of the
extendable and expandable positioning structure of a trunk bag are
illustrated.
[0028] The first embodiment is illustrated in FIGS. 1 to 4. In the
first embodiment, a slidable buckling device 4 is installed. The
bag body 1 is divided into a bag receiving portion 12 at the middle
section thereof. The bag receiving portion 12 has an upper bag 11
at the upper side thereof and a lower bag 13 at the lower side
thereof. The inner side of the upper bag 11 is connected to an
upper box frame 15. The lower bag 12 is also connected to a lower
box frame 14. The lower box frame 14 is connected to a retaining
plate 41. The retaining plate 41 is installed with at least one
long groove 42. At least one inner edge of the long groove 42 is
installed with a positioning female element 40. The positioning
female element 40 is a pair of positioning buckling legs 43. The
positioning buckling leg 43 is installed with a buckling groove
431. The two buckling groove 431 of the positioning buckling legs
at two sides are protruded outwards and are back to back. The pair
of the positioning buckling legs 43 are installed at the inner edge
of the top of the long groove 42.
[0029] The upper box frame 15 is firmly secured to a sliding block
45 at a position with respect to the long groove 42. The sliding
block 45 is installed with a positioning male element 450 at
position with respect to the positioning female element 40 so that
the positioning male element 450 is capable to be buckled to the
positioning female element 40. The positioning male element 450 is
a protruded buckle 46 protruded from the top of the upper side of
the sliding block 43. Since the positioning buckling leg 43 is
installed at the upper end of the inner edge of the long groove 42,
the protruded buckle 43 is installed, respectively. At two sides of
the protruded buckle 43 like a piece each are installed with
respective protrusion 47. The protrusion 47 may be buckled to the
buckling groove 431. The thickness of the sliding block 45 is
extended out of the long groove 42 and two outer edges 48 are
engaged with the surface of the retaining plate 41. A pair of
through holes 451 are installed at the middle portion of the
sliding block 45, and then a pair of respective retainer 49 pass
through the through holes 451 so that the sliding block 45 is
firmly secured to the upper box frame 15.
[0030] When the bag body 1 is pulled, at the upper bag 11, the
upper box frame 15 and the sliding block 45 are driven to move with
respect to the long groove 42 of the retaining plate 41 to be moved
upwards or downwards so as to be positioned. As shown in FIG. 3,
the positioning is at a position illustrated in the condition of
FIG. 4 and at position as illustrated from the solid line of the
FIG. 3 to the dashed line of FIG. 3. It is shown that the
protrusions 47 at two sides of the protruded buckle 46 protruded
from the upper end of the sliding block 45 will enforce the inner
end surfaces of a pair of positioning buckling legs 43 at the inner
edge of the long groove 43 of the retaining plate 41 to be opened
so that the protruded buckle 46 slides into the positioning female
element 40 formed by the two positioning buckling legs 43 and then
the buckling groove 431 of each positioning buckling leg 43 will
buckle the protrusion 45 of the protruded buckle 46. Thus, the
retaining positioning to the sliding block 45 of the positioning
male element 450 is accomplished. Another, the upper box frame 15
moves to an upper position from a lower position for combining and
positioning.
[0031] As shown in FIGS. 1 to 4, the lower end of the sliding block
45 is connected with an inserting rod 452. A spring 453 encloses
the inserting rod 452. The upper end of the spring 452 is
positioned. A rod groove is installed with respect to the long
groove 42. When the sliding block 45 moves downwards to be
positioned so that the inserting rod 452 is inserted into the rod
groove 421, while the spring 453 is compressed to be out of the rod
groove 421. When the box is to be opened for expansion, the sliding
block 45 will release the zipper at the bag receiving portion
12.
[0032] FIGS. 5 and 6 shows the second embodiment of the present
invention, a slidable buckling device 5 is installed. The bag body
1 is divided into a bag receiving portion 12 at the middle portion
thereof. The bag receiving portion 12 at the middle portion has an
upper bag 11 at the upper side thereof and a lower bag 13 at the
lower side thereof. The inner side of the upper bag 11 is connected
to an upper box frame 15. The lower bag 12 is also connected to a
lower box frame 14. The lower box frame 14 is connected to a
retaining plate 51. The retaining plate 5 1 is installed with at
least one long groove 52. At least one inner edge of the long
groove 52 is installed with a positioning female element 50. The
positioning female element 50 has a positioning buckling groove 53
which is installed at the inner edges at two sides of the long
groove 52.
[0033] The upper box frame 15 is firmly secured to a sliding block
55 at a position with respect to the long groove 52. The sliding
block 55 is installed with a positioning male element 550 at
position with respect to the positioning female element 50 so that
the positioning male element 550 is capable to be buckled to the
positioning female element 50. The positioning male element 550 is
installed with a retaining groove 552 at the outer lateral side
(the lateral side near the bag) on the sliding block 55. Two
lateral sides of the retaining groove 552 are installed with
respective bead hole 553 so that the retaining groove 552 can be
placed with a spring 45 conveniently. Beads 57 at two ends of the
spring 56 at two ends of the spring 56 protrudes from the bead
holes 553 of the retaining groove 552 by the elastic force of the
spring 56 so that the exposing portion of the bead 56 is buckled in
the positioning groove 53. When the sliding block 55 moves upwards,
the spring 56 will compress, so that the bead 57 is received in the
retaining groove 552 so as to be moved upwards to the positioning
groove 53 and then is elastic out for positioning. The inner
lateral surface of the sliding block 55 have two outer edges 58
which can protrude out of the long groove 52. At the outer edges 58
connected to the surface of the retaining plate 51, when the bag
body 1 is pulled upwards, the bead 57 of the sliding block 55 can
be driven to be moved upwards at the positioning groove 53 of the
long groove 52 of the retaining plate 51 so as to be
positioned.
[0034] The third embodiment of the present invention is illustrated
in FIGS. 7 to 11. In this, Two sides of the bag body 1 are
installed with respective slidable buckling devices 2. The bag body
1 is divided into a bag receiving portion 12 at the middle portion
thereof. The bag receiving portion 12 has an upper bag 11 at the
upper side thereof and a lower bag 13 at the lower side thereof.
The inner side of the upper bag 11 is connected to an upper box
frame 15. The lower bag 12 is also connected to a lower box frame
14. The lower box frame 14 is connected to a retaining plate 21.
The retaining plate 21 is installed with at least one long groove
22. At least one of the two lateral sides of the long groove 22 is
installed with a positioning female element 20. The positioning
female element 20 is a positioning buckling groove 23. The lower
end of the retaining plate 21 is connected to the lower box frame
14 through at least one retainer 24.
[0035] The upper box frame 15 is firmly secured to a sliding block
25. An elastic buckle 26 of the positioning male element 250 is
installed on the sliding block 25 at a direction with respect to
the positioning groove 23 so that on hook head 27 of the elastic
buckle 26 may be engaged to the positioning groove 23, as shown in
FIG. 8. The sliding block 25 cause the elastic buckle 26 to be
installed at the middle portion at the left and right sides of the
main body. The middle portion had a groove 261. A protruded buckle
26 at the groove 261 extends from one side (upper side illustrated
in the figure) to another side (lower side). While the protrusion
end of the protruded buckle 26 is not to connect with the groove at
another side. Near the distal end of the protruded buckle 26 is
protruded with a hook head 27. The main body of the sliding block
25 projects from the long groove 22. Two outer edges 28 are
connected to the surface of the retaining plate 21. In practical
assembly, the retaining plate 21 is at first connected to the lower
box frame 14. Then, it is fixed by the retainer 25. Then the
sliding block 25 protrudes from the long groove to be positioned to
the upper box frame 15 so as to be fixed by the retainer 29.
[0036] In using the present invention, the bag body 1 is pulled
upwards so as to drive the long groove 22 in the sliding block 25
to move upwards and downwards. Furthermore, the hook head 27 is
buckled in the positioning groove 23. Each sliding block 25 is
connected to the upper box frame 15 through a retainer 29 and is
placed near the lower end of the upper box frame 15. The retainers
24 and 29 are pins for fixing which may be correspondent to each
other.
[0037] In the aforesaid structure, FIG. 9 shows the moving
condition. That is to say, the positioning grooves 23 at the upper
and lower sides have two positioning positions for before used and
after used. However, if the bag body 1 is matched to the groove,
the positioning groove 23 may be positioning in three positions for
adjustment. The bag body 1 is a structure enclosing the surface of
the box, which may be made of soft cloth or a hard case. If it is a
hard case, in order to save material, the upper and lower box
frames may not be installed. In order to fix the appearance of the
bag body 1, similarly, in the present invention, a zipper 16 serves
to hidden the bag receiving portion 12 at the middle portion so as
to achieve the object of fixing the upper bag and lower bag. FIGS.
10 and 11 shows the embodying of the present invention, which shows
the combination of the present invention and the bog.
[0038] In summary, in the present invention, a special buckling
device is used so that the height of the box can be adjusted
without opening the box. The present invention is primary formed by
a retaining plate and a sliding block. A positioning male element
(protrusion from the protruded buckle, spring, bead, hook head of
the elastic buckle) installed on the sliding block serves to
position the positioning female element (buckling groove of the
positioning buckling leg, positioning groove, positioning buckling
groove) in the long groove by the guiding of the retaining plate.
Through the elasticity of the positioning male element, the fixing
structure connected to the positioning female element can be
adjusted rapidly. If it is pressed heavily, since the positioning
male element is slightly buckled to the positioning female element,
even a slightly releasing, no effect will apply to the objects in
the box. That is to say, if the object is too much, the box can
still be used. Therefore, the present invention has a preferred use
and provides a good variation to the content space.
[0039] Although the present invention has been described with
reference to the preferred embodiments, it will be understood that
the invention is not limited to the details described thereof.
Various substitutions and modifications have been suggested in the
foregoing description, and others will occur to those of ordinary
skill in the art. Therefore, all such substitutions and
modifications are intended to be embraced within the scope of the
invention as defined in the appended claims.
