Adjustable folding table
Abstract
This utility model discloses a type of adjustable, folding
table, composed of a table top and a table frame, wherein the table
frame comprises two cross bars, at least two longitudinal bars, two
leg sets, and two support rods, and wherein the table top comprises
two fastened and joined main table tops and at least one auxiliary
table top. The bottom of each table top is shaped to have sliding
grooves corresponding to two crossbars. The two main table tops of
this folding table slide relative to the two cross bars of the
table frame. Therefore, when it becomes necessary to increase the
area of the table top, one can move the two main table tops
relative to the cross-bars towards the two sides, join the
auxiliary table tops between the two main table tops, and set them
on the cross-bars to form a table top with a large surface area.
When it becomes necessary to reduce the size of the table top, then
one needs only detach the auxiliary table tops. After this folding
table has been folded, the auxiliary table tops can be fastened to
the underside of the main table tops, without having to take up
excess volume. Thus, it is easy to use and quite practical.

Description
TECHNICAL FIELD
[0001] This utility model relates to a type of folding table. In
particular, it relates to a type of adjustable folding table.
PRIOR ART
[0002] Increasingly high functional requirements are being placed
on modern furniture, whether of home or office, in order to make it
more practical. This is the reason that foldable furniture has
appeared. FIG. 1 shows a folding table that can be used for outdoor
activities. Its main components are a table top 1' and a table
frame 2', comprising cross-bars 21', longitudinal bars 22', two leg
sets 23', and two support rods 24'. The cross-bars 21' are fixed to
the underside of the table top 1'. The longitudinal bars 22' are
separately and pivotally attached to the two ends and the center of
the two cross-bars 21'. The two leg sets 23' are separately fixed
to the two ends of the longitudinal bars 22'. The support rods 24'
are secured, at one end, to the table legs 23'. At the other end,
they are pivotally attached to the longitudinal bar 22' at the
center of the cross-bars 21'.
[0003] When one wants to carry or store it, one turns the table top
1' face down, and forcefully pulls down the legs 23'. Because of
the pivotal connections between the table legs 23' and the
longitudinal bars 22' and between the support rods 24' and the
table legs 23', the legs 23' come to rest on the underside of the
table top 1', thereby reducing its volume and performing its
folding function.
[0004] However, in the folding table with this structure, the area
of table top 1' is fixed. It is not possible to adapt it to
different numbers of people.
[0005] Contents of the Utility Model
[0006] The goal of this utility model is to provide a type of
folding table with an adjustable table top area.
[0007] To reach the above-stated goal, the solution of this utility
model is: an adjustable folding table, composed of a table top and
a table frame, wherein the table frame comprises two cross-bars, at
least two longitudinal bars, two leg sets, and two support rods,
and wherein the table top comprises two main table tops fastened
and joined together and at least one auxiliary table top. The
bottom of each table top is shaped to have sliding channels that
correspond to two cross-bars.
[0008] Inside the sliding channels of said two main table tops,
steel channels are separately fixed to couple and slide with the
cross-bars. Between the steel channels and the cross-bars are
provided support blocks to prevent rocking of the table top and the
cross-bars with respect to each other.
[0009] Opposing sides of said two main table tops are shaped to
have mutually fastening protruding portions and recessed portions,
and two sides of the auxiliary table top are also shaped to have
protruding portions and recessed portions that correspond to and
couple with the two main table tops.
[0010] The underside of the main table tops is provided with
protruding portions or recessed portions that fasten to the
auxiliary table top, and, corresponding to said protruding portions
or recessed portions, the bottom of the auxiliary table top is also
shaped to have recessed portions or protruding portions.
[0011] The sides of said recessed portions are shaped to have
grooves or ridges.
[0012] The sides of said protruding portions are shaped to have
ridges or grooves.
[0013] Because, in using the above-described structure, the two
main table tops of this folding table slide relative to the two
cross bars of the table frame, when it becomes necessary to
increase the area of the table top, one can move the two main table
tops relative to the cross-bars towards the two sides, join the
auxiliary table tops between the two main table tops, and set them
on the cross-bars to form a table top with a larger surface area.
When it becomes necessary to reduce the size of the table top, then
one need only detach the auxiliary table tops. After this folding
table has been folded, the auxiliary table tops can be fastened to
the underside of the main table tops, without having to take up
excess volume. Thus, it is easy to use and quite practical.

SPECIFIC EMBODIMENTS
[0022] A type of folding table of this utility model, as shown in
FIGS. 2, 3 and 4. Its main components are a table top 1 and a table
frame 2.
[0023] The table top 1 comprises two main table tops 11 and at
least one auxiliary table top 12. (There are two auxiliary table
tops in this embodiment.)
[0024] The bottoms of the two main table tops 11 are shaped to have
sliding channels 111. Secured to the insides of the sliding
channels 11 are steel channels 3. Opposing sides of the two main
table tops 11 are shaped to have mutually-fastening protruding
portions 112 and recessed portions 113. The coupling surfaces of
the protruding portions 112 and the recessed portions 113 are
provided with ridges 1121 and grooves 1131. The bottom surface of
the main table tops 11 is provided with recessed portions 114 for
fastening the auxiliary table tops 12. The coupling surfaces of the
recessed portions 114 are also provided with grooves 1141.
[0025] Two sides of the auxiliary table tops 12 are shaped to have
protruding portions 121 and recessed portions 122 corresponding to
and coupling with the main table tops 11, and its coupling surfaces
are also provided with ridges 1211 and grooves 1221. The bottoms of
the auxiliary table tops 12 are shaped to have protruding portions
123 corresponding to the aforesaid recessed portions 114 of the
main table tops 11, and their coupling surfaces are also provided
with ridges 1231.
[0026] The table frame 2 comprises two cross-bars 21, four
longitudinal bars 22, two leg sets 23, and two support rods 24,
wherein:
[0027] The cross-bars 21 are mobilely nested together with the
steel channels 3. Between the cross-bars 21 and the steel channels
3, support blocks 4 are provided to prevent rocking between the
cross-bars 21 and the steel channels 3. The support blocks 4 are
fixed to the steel channels 3 and can slide relative to the
cross-bars 21.
[0028] The longitudinal bars 22 are separately and pivotally
attached to the two ends and centers of the two cross-bars 21. The
two leg sets 23 are separately fixed to the longitudinal bars 22 of
the two ends. The support rods 24 are fixed at one end to the legs
23 and at the other end are pivotally attached to the longitudinal
bars 22 of the center of the cross-bars 21.
[0029] During assembly, as shown in FIG. 4, after setting the two
main table tops 11 on the table frame 2, all the protruding
portions 112 and all the recessed portions 113 of the main table
tops 11 separately fasten and couple with each other to form a
table.
[0030] As shown in FIGS. 5 and 6, when the area of the table top 1
needs to be expanded, apply force to pull apart the two main table
tops 11. At this point, because the steel channels 3 under the main
table tops 11 are nested together with the cross-bars 21 of the
table frame 2, the table tops 11 can drive the steel channels 3 and
support blocks 4 so that they slide relative to the cross-bars 21.
Then fasten the auxiliary table tops 12 between the two main table
tops 11. Couple and fasten with the protruding portions and
recessed portions of each table top to assemble a table with a
table top 1 that has a larger area.
[0031] As shown in FIG. 7, when it is necessary to increase the
area of the table top 1, one can accomplish this goal by adding two
or more auxiliary table tops 12.
[0032] As shown in FIG. 8, when the folding table of this utility
model is folded, first detach the auxiliary table tops 12 from the
two main table tops 11. After joining the two main table tops 11,
turn them face down and forcefully pull down the table legs 23.
Because of the pivotal relations between the legs 23 and the
longitudinal bars 22 and between the support rods 24 and the legs
23, the legs 23 will come to rest on the underside of the table top
1. Then, use the protruding portions 123 shaped on the bottom of
the two auxiliary tables 12 to fasten them to the recessed portions
114 of the bottom surface of the main table tops 11 and thus
achieve a reduction in its folded volume.
