Description
FIELD OF THE INVENTION
[0001] This invention relates to a container for disk, which can
evenly balance the disk inside and prevent the disk from being
damaged during use, delivery or transport.
BACKGROUND OF THE INVENTION
[0002] Most of the existing containers adopt central support to
hold the disk. For example, in the product with Chinese Patent No.
00262204.1, the area of the compact disk contacting the central
support is designed smaller, and the disk is easy to incline
inside. The surface of the data area may be scratched in case of
negligence. Meanwhile, the disk will be forced to deviate the
support base by the pressing force owing to the insufficient
rigidity of the support base, so, affecting the sound effect and
the image quality.
OBJECTS AND SUMMARY OF THE INVENTION
[0003] The object of the present invention is to provide a new disk
container to improve the containers in many aspects, including
optimizing structure of the central support, decreasing the
pressure of the button, strengthening the hardness of the support,
setting the central ring and enlarging the central support area for
the non-data area.
[0004] According to the present invention, there is provided a disk
container, the back side of said container is respectively
connected with the bottom side and the cover side; the container is
formed by folding the three sides, that is the bottom, the back and
the cover; a disk support is designed on the inner side of the
container bottom and composed of connecting button, elastic small
sector and locking slip; a small ring is located at the outer
circular on support base of the bottom.
[0005] The diameter of the small ring is smaller than that of the
central non-data area, and vertically placed to the inner side of
the container bottom; the vertical height of the small ring is as
same as that of the larger arc shoulder designed on the big sector
area on the upside of the container bottom.
[0006] On the core of the support base, the top is a ring-type core
neck composed of a pair of rigid disk protection slip and elastic
locking slip; the diameter of the protection slip is a bit bigger
than that of the locking slip; the height of the disk protection
slip is a bit higher than that of the locking slip and the
button.
[0007] The vertical height of the small ring is as same as that of
the inner ring of larger outer gear-shaped circle and the arc
shoulder on the outer ring, thus form the disk supporting
assembly.
[0008] The three radial lines from the sector centre in the
container bottom is connected in segments with the small ring,
hence forming the central rigid supporting assembly, the height of
the extending enforced tendon is a bit lower than that of the small
ring.
[0009] The protruding paper-holding spring with long arc existed on
the center of the container back The length of the protruding arc
is a bit shorter than that of the container back.
[0010] The bottom side of the container exists a large ring
supporting base.
[0011] Compared with the prior art, this invention offers a elastic
bridge structure with rigid and flexible interaction composed by
the button, small elastic sector and the locking slip. And this
container is also designed with a small circular support ring,
hence, avoiding the problems such as the smaller support area in
the central support base and the imbalance of the support force
borne by the disk. Meanwhile, a concave slot is designed in the
position between the button bottom and the bottom of the small
sector area so that the button can evenly distribute the axial
pressing force in surfaces of the two elastic bridge, hence, it
becomes easier and more convenient to hold the disk, with excellent
reliability, safety and endurance.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0031] As shown in the figures, the container back 13 is
respectively connected with the container bottom 12 and the
container cover 11; a book-like container is formed by folding the
container bottom 12, the container back 13 and the container cover
11 together; a disk support base 18 is designed in the inner side
of the container bottom 12; said support base 18 includes button
21, a pair of small elastic sector area 15 and locking slip 20,
which form a straight elastic bridge together with connection piece
15D and the concave slot 28; The button 21 is a cylindrical button
with a flat top; said a pair of small sector area 15 is in symmetry
of the core of the disk support base; the two ends of the elastic
bridge are connected with the cone-shaped pier 15A and extended to
be connected with the base of the small ring 26; the small elastic
sector area 15 is designed with a locking slip 20 which is equipped
with a locking wing 20A.
[0032] The disk support base 18 also includes a rigid support large
sector area 16, which is respectively connected with the inner side
of the container bottom 12 in segments by the rigid tilting surface
16C and small ring 26. The small ring 26 is vertical to and
connected with the container bottom. The rigid support large sector
area 16 is designed with an arc support shoulder 17 and disk
protection slip 19. On the top of the core of the support base 18,
a ring neck is formed by a pair of rigid disk protection slip 19
and a pair of elastic locking slip 20 in segments. The diameter of
the protection slip 19 is a bit bigger than that of the locking
slip 20, but a bit smaller than the diameter of the central hole of
the disk. A segment circle is formed by the rigid disk protection
slip 19 and the locking slip 20. The protection slip 19 is vertical
to and connected with the larger sector area 16. And the height of
the disk protection slip 19 is a bit higher than that of the
locking slip 20 in its static status. The small ring 26 has the
same core with arc shoulder 17 over the rigid support large sector
area 16. Besides, the small ring 26 has the same height with the
arc shoulder 17 and the protrudent support shoulder 12D of the
bottom 12.
[0033] The support base 18 also includes three radial strengthening
tendons designed in the back of the container bottom 12. With the
core of the large sector area 16 as the radial point, the tendon
extends along the base of the sector area and the central line of
the sector area to form three radial lines 16A, 16B, these three
radial lines 16A, 16B extend to the rigid tilting surface 16C in
the inner side of the container bottom and form enforced keels 27,
which are respectively connected with the rigid tilting surface 16C
and the small ring 26. The enforced keels 27 have the same height
with the radial lines 16A, 16B.
[0034] The center of the container back 13 is designed with an
extended and protrudent arc baffle 13A, which enhances the rigidity
of the container back and prevents the container from being
deformed.
[0035] The container is designed with a cylindrical button 21 with
a flat top. And a straight elastic bridge is formed by the button
21, a pair of small sector area 15 with the core of the support
base 18 as the symmetrical point and the concave slot 28. The two
ends of the elastic bridge are connected with the cone-shaped pier
15A. When adding pressing force, the bridge will elastically sink
to become a concave arc, the concave slot 28 and the cone-shaped
pier 15A will incline towards the center. When the pressing force
is released, the bridge will quickly return to its original
position owning to its upward elasticity and the transverse
eccentric force from the two ends of the cone-shaped pier applied
to the bridge. At the same time, the concave slot 28, the locking
wing 20A of the locking slip 20 and the button 21 will also quickly
return to their original position.
[0036] The central button 21 and the arc locking slip 20 which is
symmetric to the button 21 and with some extended space are located
in the two ends of the bridge center. The cylindrical button 21 is
located in the center of the bridge. When force is applied to the
button 21, it will be transmitted to the concave slot 28 at the two
ends of the bridge center and the small sector area 15 through the
base of the button 21. The force applied to the two ends of the
bridge will cause the bridge surface to elastically deform at the
central point as the symmetrical position. Meanwhile, the concave
slot 28 connected with the bridge surface, the locking slip 20 and
the locking wing 20A in the top will also be turned inward, with
even downward shift along the axial direction. When the diameter of
the locking wing 20A is smaller than that of the central hole of
the disk, the central hole of the disk shall upward deviate the
core neck and locking wing along the axial direction, the lower
edge of the center hole will be placed over the locking wing 20A.
The location of concave slot 28 will make the central button 21
become easy, convenient and safe to be touched on by finger.
[0037] The small ring 26 has the same core with the center of the
small sector area 15 and the large sector area 16, the outside
diameter of the small ring 26 is a bit smaller than that of the
non-date area near the central hole of the disk. The small ring 26,
the protrudent support shoulder 12D of the large ring and the arc
shoulder 17 on the rigid large sector area 16 have the same height,
with the function of effectively supporting the non-data area of
the disk. The disk will be kept at the same level without any
distortion.
[0038] The outer diameter of a pair of the arc protection slip 19
is greater than that of the arc locking slip 20, but a bit smaller
than that of the central hole of the disk. The disk protection slip
19 is a bit higher than the button 21 in its natural status, with
the functions of placing the disk and protecting the button from
being activated so as to securely holding the disk when the
container is closed.
[0039] The small ring 26 and the enforced keels 27 not only enhance
the strength of the whole support base 18, preventing it from being
deformed, but also keep the front and back surfaces of non-data
area on the disk from being affected its stable storing owing to
the pressing force from axial and diameter direction. In addition,
the whole structural assembly of the support base 18 shall
permanently retain the designed position, avoid of deformation.
[0040] When container is used to hold the disk, the edge of the
central hole of the disk 25 shall be put right toward the disk
protection slip 19A, the two locking slips 20 and the above locking
wing 20A. Under the navigation of the disk protection slip 19, the
locking wing 20A shall hold the two symmetrical edges 25A of the
central hole of the disk 25, making the disk stay in the temporary
suspension status. When applying moderate force to lightly press
the disk, the two locking wings 20A will receive downward axial
pressing force from the edge of disk center hole. The force shall
be transmitted to the locking slip 20, the concave slot 28 and the
elastic bridge surface 15C which appears to be concave surf, when
the diameter of two locking wings 20A is smaller than the diameter
of 25A, the incline degree of the elastic bridge surface 15C will
be close to the maximum value. In this case, the edge 25A of the
central opening of the disk 25 shall move downward through the
locking wing 20A due to the push of the finger. And the non-data
area of the disk shall contact the rigid arc shoulder 17 on the
large sector area 16, the small ring 26, arc shoulder 12C and the
protrudent support shoulder 12D inside the large ring. Meanwhile,
the elastic force from the pier 15A and the elastic bridge surface
15C will be released; the concave slot 28, the locking slip 20 and
the locking wing 20A will quickly return to their original
position; the locking slip 20 and the locking wing 20A will be
meshed with the relevant position on the edge of 25A. The center
non-data area and edge non-data area on the disk are evenly
positioned on the symmetrical and rigid arc support shoulder 17,
small ring 26, arc shoulder 12C and the outer arc-shaped protrudent
support shoulder 12D. Due to the three enforced radial lines 16A
and 16B of the large sector 16 extending to the inner side of the
ring 26 to form enforced keels 27 along the rigid tilting surface
16C, the strength of the support base 18 is enhanced. In addition,
the small ring 26, the arc shoulder 12C, the outer circular
protruding support shoulder 12D respectively and properly support
the non-data area of the disk 25 and the outer edge of the disk
25B, so the disk can be stably located on the support base 18. The
button 21 and the locking slip 20 are a bit lower than the disk
protection slip 19. The rigid disk protection slip 19 may resist
the external force and prevent the button 21 from being improperly
activated owing to the force. Then close the cover 11. Now the
inner arc disk pressing slip 11 C and the extended arc spring 13A
on the container back 13 will moved consequently, so as to be
closed with the container bottom 12, also the edge of the under
surface of the disk 25C is symmetrically limited inside the large
ring. The spring 13A can not only firmly holding the disk and
instruction of the disk, but also enhance the rigidity of the
container back. Therefore, the container can bear more pressing
force, in avoid of being damaged caused by pressing or over-weight
during transportation or moving.
[0041] When taking out the disk, the user shall lightly press the
button 21 which evenly transmits the force to the concave slot 28
and the elastic bridge 15C. With the equal downward axial force
from reverse direction, the bridge 15C shall gradually sink to
become the concave surface; the two locking slips 20 and the above
locking wing 20A shall shrink toward the center in the radial
direction and downward in the axial direction due to the light
distortion force of the concave slot 28. Due to the the three
radial lines 16A, 16B on the back of the two large sector area 16
respectively extending to the inner surface of the container bottom
to form the enforced keels 27 and the small ring 26 in the inner
surface of the container to form the rigid support base so as to
resist the elastic pressing force, hence firmly holding the
non-data area of the disk and preventing the supported disk from
being deformed owing to the elastic force. When the diameter of the
two locking wings 20A is forced to be less than that of the central
hole 25A of the disk 25 by the pressing force from the button 21,
the central hole 25A of the disk 25 shall not be affected by the
friction force from the locking wing 20A, and the disk shall move
upward. Then the gradient of the elastic bridge 15C shall be close
to the maximum value. The arc shoulder 17 on the larger rigid
sector area 16 is designed to share the same surface with small
ring 26 in order to prevent the disk from moving downward. When the
pressing force of the button 21 is released, the locking wing 20A
shall firstly return to the initial outer position along the radial
direction; the top of the locking wing 20A shall hold the edge of
the lower surface of the central hole 25A of the disk 25. Under the
force of the elastic bridge 15C, the whole disk shall quickly move
upward with the navigation of the disk protection slip 19, and be
ejected from the support base 18. Then the disk shall be easily
taken out.
[0042] Compared with the prior art, the present invention has the
following achievements and advantages:
[0043] 1. The small ring is designed to enhance the rigidity of the
core base, so as to obtain the stable, safe and reliable
effect.
[0044] 2. A concave slot is designed in the connection between the
elastic bridge and the button, hence making the connection parts
smaller and thinner, decreasing the pressing force of the button
and increasing the elastic force for returning to the original
position, making it easier and more convenient to take out the
disk.
[0045] 3. The disk protection slip is a bit higher than the locking
slip, thus effectively preventing the pressure on the core base
from the outside of the container cover, preventing the central
hole of the disk from deviating the support base, effectively
protecting the disk from deviating the support base.
[0046] 4. The three radial enforced tendons on the rear of the
container bottom extend to the inside of the container and connect
with the small ring to form the core base with greater stability
and rigidity, hence effectively prevent the disk from being
deformed and damaged. Meanwhile, they shall restrict the two large
sector areas on the core base from being tilted and deformed owing
to the external force.
