Background of the Invention
1. Field of the Invention
[0001] The present invention relates to a display unit for storing a tool assembly, especially
a support for a tool assembly (such as sleeves), where the support is moveable and
rotatable with respect to a base (not about a fixed axis of rotation) such that the
tool assembly can be easily retrieved to use and stored in the display unit safely
and securely. The present application claims priority from PRC Patent Application
No. 200410091140.0.
2. Description of the Related Art
[0002] Fig. 1 shows a conventional display unit 100 for tool assembly. The display unit
100 comprises a base 101 with a plurality of slots 102 formed thereon for accommodating
a plurality of tool assembly parts such as sleeves 103. A fence 104 is disposed at
the front end of the base 101 to prevent the sleeves 103 from falling or sliding out
of the base 101. A lid 105 is disposed at the top rear edge of the base 101 and two
latches 106 are disposed at the front end of the lid 105. A slot 107 is formed in
each of the latches 106 to engage the corresponding protrusion 108 disposed at the
front end of the base 101 such that the sleeves 103 are received in the slots 102.
A slot 110 is formed at opposite sides of the lid 105 to engage a corresponding protrusion
109 disposed at the top opposite sides of the base 101. When retrieving sleeves 103,
a user has to manually disengage the two latches 106 with the protrusions 108 and
the slots 110 with the protrusions 109, respectively, to open the lid 105 first. With
this configuration, if sleeves 103 are received in the slots 102 too loosely, the
sleeves 103 may be likely to fall or slide out from the display unit 100 in the user's
hand when shaking. If the sleeves 103 are received in the slots 102 too tightly, although
the sleeves 103 can be secured to the base 101 effectively, it may not be easy to
retrieve the sleeves 103 when in a rush as they may be stuck in the slots 102. In
addition, as the lid 105 engages the base 101 by way of latching, it is likely to
break the latches 106 or protrusions 108, 109 when closing the lid 105, which render
the lid 105 unable to secure the sleeves 103 and therefore makes the display unit
100 useless.
[0003] Fig. 2 shows the other conventional display unit 200 for tool assembly comprising
a base 201. A shaft 202 spaced from and parallel to an inner surface of the base 201
is disposed in the base 201 for accommodating securing means 203. Rotation means is
disposed in the shaft 202 such that the securing means 203 can be rotated to a certain
angle respect to the base 201 and shaft 202. A fence 205 is disposed at one end of
the base 201 for preventing sleeves 204 from falling or sliding out of the base 201
or inappropriate retrieval. A rod 206 is disposed between the securing means and the
base 201 for preventing the securing means 203 from rotating when the sleeves 204
are in place and therefore ensuring a secured package. When the sleeves 204 are being
retrieved, one end of the rod 206 has to be cut and removed first and the sleeves
204 are then rotated and retrieved. However, such configuration is considered complicated,
inconvenient and spacey.
[0004] From the above, it is necessary for the industry to provide a display unit which
is easier to use, less spacey and can overcome the defects mentioned in the prior
art.

Detailed Description of the Invention
[0009] Figs. 3 to 5 illustrate exploded and schematic views of a display unit for storing
a tool assembly according to the present invention. The display unit 1 for storing
a tool assembly comprises a base 11, a moving-rotating mechanism and a support plate
13. The base 11 has a front end 111, a rear end 112 opposite the front end 111 and
two opposite sides 113. The moving-rotating mechanism comprises at least one moving-rotating
device 12. The support plate 13 has a front end 131 and two opposite sides 132 for
supporting the tool assembly, such as sleeves 14. At least one of the two opposite
sides 113 of the base 11 is coupled to at least one of the two opposite sides 132
of the support plate 13 by at least one moving-rotating device 12. As shown in the
figures, preferably each of the two opposite sides 113 of the base 11 is coupled to
the corresponding one of the two opposite sides 132 of the support plate 13 by the
respective moving-rotating device 12 such that the front end 131 of the support plate
13 is moveable and rotatable from a first position at the front end 111 of the base
11 (referring to Fig. 5 and the topmost view of Fig. 6A) to a second position at the
rear end 112 of the base 11 (referring to Fig. 4 and the bottommost view of Fig. 6A).
[0010] Now referring to Fig. 3, each of the moving-rotating devices 12 comprises a wing
121, a guiding slot 122 and a protrusion 123. The wing 121 is disposed perpendicularly
at each of the two opposite sides 113 of the base 11 while the guiding slot 122 is
formed in the wing 121. The protrusion 123 is disposed transversely at each of the
two opposite sides 132 of the support plate 13. When each of the two opposite sides
113 of the base 11 is coupled to the corresponding one of the two opposite sides 132
of the support plate 13, each protrusion 123 is then moveable and rotatable along
the guiding slot 122 of the wing 121. The guiding slot can be an arc curvedly extending
upwards and backwards (referring to Figs. 3 to 5), or can be a straight line shape
extending backwards (referring to reference numeral 122' in Fig. 7). The guiding slot
122 comprises a front section 1221 and a rear section 1222 and each section has a
narrowing neck 1223 formed thereof. When the protrusion 123 passes through the neck
1223, the protrusion 123 is provided with a proper friction force such that the protrusion
123 of the support plate 13 can be properly positioned at the front section 1221 or
the rear section 1222.
[0011] As mentioned above, the support plate 13 is for supporting tool assembly parts such
as sleeves 14. The sleeves can be a set with continuous or different sizes. The support
plate 13 can also comprise a plurality of supports 133 and each supports the corresponding
sleeve 14. Each of the sleeves 14 can be tightly fitted to the corresponding support
133, or can be loosely fitted to the corresponding support 133. Preferably, when the
sleeves 14 are loosely fitted to the corresponding supports 133, a stopping device
114 is further disposed at the front end 111 of the base 11 such that when the front
end 131 of the support plate 13 is moved and rotated to the second position at the
rear end 112 of the base 11, because the sleeves 14 contact the stopping device 114
and press the stopping device 114 which generates an elastic force against the sleeves
14, the stopping device 114 is then adapted to prevent the sleeves 14 from separating
or sliding from the supports 133 (referring to Figs. 4 and 6A), which in turn, secures
the sleeves 14 to the base 11. Similarly, when the front end 131 of the support plate
13 is moved and rotated to the first position at the front end 111 of the base 11
from the second position, because the sleeves 14 gradually disengage the stopping
device 114 which releases the elastic force, the sleeves 14 can return to a free state
from a secured state (referring to Figs. 5 and 6B). The stopping device can be of
any suitable design. As shown in Fig. 7, the stopping device can comprise a plurality
of stoppers 114' and each substantially corresponds to the respective support (not
shown in figure). The stoppers can also be removably mounted at the front end of the
base (referring to Fig. 12), or slidably mounted at the front end of the base (referring
to Fig. 13). The supports 133 as shown in Fig. 3 can also be modified to adjustable
supports 134 shown in Fig. 9, which can move along a slot 135 disposed in a support
plate 13' to suit sleeves of different sizes or quantity. In addition, supports 136
of a convex type shown in Fig. 10 or supports 137 of a concave type can also be employed
without departing from the spirit of the present invention.
[0012] From the above descriptions, it is apparent that the present invention provides a
display unit which has a simple configuration and stability and is easy to manufacture
and use. Not only can it be used alone, but it can also be employed in conjunction
with other tool display units. As shown in Figs. 14 and 15, a tool display 20 can
comprise a housing 21 having a bottom end 11' and two opposite sides defining two
displaying spaces. A display unit 1' can be received in one of the displaying spaces,
while the other displaying space can be used to receive tools such as wrenches, which
in turn, forms an integral and complete tool package to enhance the value of the product
and catch consumers' eyes. Preferably, the bottom end 11' of the housing 21 is an
extension of the base of the display unit 1' and each of the two opposite sides of
the tool display 1' is an extension of the corresponding wing 121'. It is possible
that the two displaying spaces can also be individually defined spaces where the bottom
end and the opposite sites of each are coupled to each other.
