shells 3, 4 is provided with wheels 5. The wheels 5 are disposed on the front and
rear shells 3, 4 which are independent structures from each other, therefore, the
height positions of the wheels 5 are difficult to control during the assembling process,
which will cause wobbling of the wheels 5 when the assembling of the hard luggage
case 1 is completed. Therefore, a wheel mounting seat capable of covering the bottom
of the hard luggage case 1 is used to improve the accuracy of installation of the
wheels 5. However, the wheel mounting seat is still an independent structure, the
bottom of the

DETAILED DESCRIPTION
[0011] The present invention will be clearer from the following description when viewed
together with the accompanying drawings, which show, for purpose of illustrations
only, the preferred embodiment in accordance with the present invention.
[0012] Referring to Figs. 3-15, a hard luggage case in accordance with the preferred embodiment
of the present invention comprises: a case body 10, a cover 40, a connecting assembly,
and four wheels 50.
[0013] The case body 10 includes a top portion 100, a bottom portion 101, a left lateral
portion 102, a right lateral portion 103, a connecting portion 31 and a back portion
104. The top portion 100 and the bottom portion 101 are connected to the left lateral
portion 102, the right lateral portion 103 and the back portion 104. The connecting
portion 31 is connected to the left lateral portion 102, the right lateral portion
103 and the bottom portion 101. The height of the connecting portion 31 is smaller
than that of the back portion 104, so as to form an opening 11 above the connecting
portion 31. The case body 10 includes an inner space 12, and the opening 11 communicates
with the inner space 12. The bottom portion 101 is an independent unitary structure
and includes a plurality of connecting ends 32, and each of the connecting ends 32
is in the form of a cavity formed at each of the four corners of the bottom portion
101. The back portion 104 is provided with a draw bar 20.
[0014] In this embodiment, the connecting portion 31 extends horizontally outwards from
the bottom portion 101 by a width W and then extends upwards by a height H, as shown
in Figs. 9-13, an arc-shaped concave portion 120 is located at lower end of each of
two lateral edges of the opening 11 to connect the connecting portion 31.
[0015] The cover 40 is pivoted to the edge of the opening 11 of the case body 10 by the
connecting assembly 41. The design of the arc-shaped concave portion 120 greatly facilitates
the assembling of the cover 40, and the connecting assembly 41 can be disposed at
different positions according to the direction the cover 40 opens. For example, as
shown in Figs. 8 and 9, the cover 40 can be side open or top open, and the connecting
assembly 41 can be a zipper. As shown in Figs. 6-9, the connecting assembly 41 is
disposed around the peripheral edge of the cover 40 and the opening 11 of the case
body 10. As shown in Figs. 10-12, the connecting assembly 41 can be a clip assembly
which includes a plurality of clipping pieces and clipping rings disposed at corresponding
positions on the cover 40 and the case body 10. Or as shown in Figs. 13-14, the connecting
assembly 41 can be a magnetic assembly which includes pairs of magnets (or magnets
and objects attracted to magnetically attractive objects, such as iron metal) disposed
at corresponding positions on the cover 40 and the case body 10. Or as shown in Fig.
15, the connecting assembly 41 includes a locking member 411 and a retaining seat
412 disposed at corresponding positions on the cover 40 and the case body 10. The
locking member 411 can be a combination lock which cannot be opened unless a correct
sequence of numbers is known.
[0016] The four wheels 50 are disposed at the four connecting ends 32 of the bottom portion
101.
[0017] The key characteristic of the present invention is the improvement to the case body
10. The case body 10 is an integral structure, there is the connecting portion 31
of H height at the lower end of the opening 11 to connect the bottom portion 101.
The four connecting ends 32 of the bottom portion 101 are in the form of cavities
which have the same depth, and each of the connecting ends 32 is provided with the
same wheel 50, so that the wheels 50 can be maintained at the same level.
[0018] Besides, since the case body 10 is an integral unitary structure provided with the
connecting portion 31, the design of the connecting portion 31 can improve the anti-collision
strength of the case body 10, strengthen the structure strength of the bottom portion
101 of the case body 10, and enable the luggage case to stand firmly without falling.
[0019] Furthermore, the inner space 12 of the case body 10 is provided for carry objects,
the draw bar 20 allows the user to pull the luggage case, and the cover 40 is connected
to the edge of the opening 11 by the connecting assembly 41. The connecting assembly
41 ensures that the cover 40 is locked to the case body 10, which prevents the opening
of the cover 40 during transportation of the luggage case, consequently preventing
dropping of the objects from the inner space 12 of the case body 10.
[0020] When the luggage case is big, with the wheels 50 directly mounted to the bottom portion
101 of the case body 10, forces will all be acted directly on the wheels 50, which
improves the stability and smoothness when the case body 10 moves or stands upright.
The luggage case is less likely to fall or tilt over since the ground contact area
is increased. Besides, since the bottom portion 101 covers the wheels 50 of the case
body 10, the bottom structure strength of the case body 10 is strengthened.
[0021] While we have shown and described various embodiments in accordance with the present
invention, it is clear to those skilled in the art that further embodiments may be
made without departing from the scope of the present invention.
