Description
FIELD OF THE INVENTION
[0001] The present disclosure deals with table tennis tables.
BACKGROUND
[0002] Table tennis is a racket sport played on a table with a hard
playing surface. A net divides two halves of the table and players
standing on opposite ends of the table take turns hitting a ball
back and forth over the net with a racket. A base is typically
attached to the playing surface to keep the playing surface at a
fixed height above the ground and to keep the playing surface from
shifting during play.
[0003] Often, assembling a table tennis table can be a lengthy
process, as the base must be securely attached to the playing
surface. Additionally, although the table tennis table may take up
a lot of space when not in use, it is often too time consuming to
disassemble the table and then reassemble the table when it is
needed. Some table tennis tables are foldable to reduce the storage
space needed. Other table tennis tables are capable of being split
into four sections allowing for easier display in stores or for
easier transportation. However, for these tables the seams between
adjacent quarter sections are present on the playing surface of the
table and can cause bad bounces, decreasing the quality of game
play.
[0004] Thus, there is a need for improvement in this field.
SUMMARY
[0005] Certain embodiments include a collapsible table tennis table
that is capable of being arranged in a collapsed configuration for
storage and an expanded configuration for game play. The table
tennis table has a table top having a top surface and a bottom
surface. The table top includes a first table section and a second
table section separated by a seam and typically connected by one or
more hinges. The second table section is foldable with respect to
the first table section about the one or more hinges. In use, a
vertical table tennis net extends substantially perpendicularly
from the top surface of the table top and across the width of the
table top.
[0006] The table tennis table includes a base assembly that has a
plurality of legs. The legs are adjustably spaced so that the base
assembly has an adjustable length and an adjustable width. Each leg
includes a telescoping pole that extends between a table pad and a
floor pad. Struts extend from each leg along the length and the
width of the base assembly to each adjacent leg.
[0007] The base assembly is configurable between a collapsed
configuration and an expanded configuration in which the base
assembly has a greater length and width than in the collapsed
configuration. The telescoping poles allow the length of the legs
to change to accommodate the change between the collapsed
configuration and the expanded configuration. Each of the legs has
a longer length in the collapsed configuration and adjusts to a
shorter length in the expanded configuration.
[0008] For game play, the table top is supported by the plurality
of legs of the base assembly with the base assembly in the expanded
configuration. In some embodiments, the base assembly includes a
total of six legs. Two of the legs support an outer end of the
first table section and two more legs support an outer end of the
second table section. The middle two legs support the table top
along the seam and contact both the first table section and the
second table section.
[0009] Further forms, objects, features, aspects, benefits,
advantages, and embodiments of the present invention will become
apparent from a detailed description and drawings provided
herewith.

DESCRIPTION OF THE SELECTED EMBODIMENTS
[0025] For the purpose of promoting an understanding of the
principles of the invention, reference will now be made to the
embodiments illustrated in the drawings and specific language will
be used to describe the same. It will nevertheless be understood
that no limitation of the scope of the invention is thereby
intended. Any alterations and further modifications in the
described embodiments, and any further applications of the
principles of the invention as described herein are contemplated as
would normally occur to one skilled in the art to which the
invention relates. One embodiment of the invention is shown in
great detail, although it will be apparent to those skilled in the
relevant art that some features that are not relevant to the
present invention may not be shown for the sake of clarity.
[0026] The present disclosure pertains generally to the field of
table tennis tables and more particularly to a collapsible table
tennis table. In certain embodiments, the table tennis table
includes a table top and a base assembly which are separable from
each other. In the illustrated embodiment, the table top is formed
from at two sections. In a collapsed configuration, the two
sections are folded with respect to each other and the base
assembly is collapsed. In an expanded configuration, the two
sections are adjacent each other and lie in the same plane and the
base assembly is expanded.
[0027] The base assembly is formed from two or more legs. Each leg
includes a telescoping pole positioned between a table pad and a
floor pad. Each of the legs is connected to an adjacent leg using
at least one strut that extends from the table pad of a first leg
to a floor pad of an adjacent leg. In some embodiments, each leg is
connected to each adjacent leg using two struts. The second strut
extends from the floor pad of the first leg to the table pad of the
second leg. The first strut and the second strut form a pair of
struts connected at a pivot point where the first strut and second
strut cross so that the two struts are arranged between the
adjacent legs to form a deformable X-shape.
[0028] The base assembly includes a collapsed configuration and an
expanded configuration. In the collapsed configuration, the struts
connecting the legs of the base assembly are arranged to be
substantially vertical so that the struts are close to parallel to
the legs. In this position, each leg is positioned close to the
attached adjacent legs and in some instances may be touching an
adjacent leg or legs. To expand the base assembly into the expanded
configuration, the legs are moved away from each other. As the
distance between the legs increases, the struts pivot with respect
to the legs, moving from being substantially parallel to the legs
to being at an oblique angle with to respect to the legs.
[0029] Additionally, as the legs of the base assembly are spread
farther apart, the telescoping pole allows the height of the legs
to change to accommodate the changing distance between each
adjacent leg. The height of each leg is reduced as the distance
between legs is increased, while the height of each leg is
increased as the base assembly is collapsed.
[0030] With the base assembly in the expanded configuration, the
table top is placed on top of base assembly. Each leg of the base
assembly provides support to the table top so that the table top is
kept level and forms a surface on which to play table tennis.
[0031] FIG. 1 is a view of a representative embodiment of a table
tennis table 20 in an expanded configuration. Table tennis table 20
includes a table tennis net 25, a table top 30 and a base assembly
50. Table top 30 rests on top of base assembly 50. In some
embodiments, table top 30 is attached to base assembly 50 using an
adhesive or other suitable attachment mechanism such as screws,
bolts, or Velcro.RTM. fasteners. In other embodiments, table top 30
is placed on base assembly 50 without the use of an attachment
mechanism.
[0032] Table tennis net 25 may extend between a pair of posts and
is held in tension. The posts may be clamped to opposing sides of
table top 30 across the width or may be attached to table top 30
using any other suitable method such as fasteners or adhesive.
Table tennis net 25 extends vertically from table top 30 so that
table tennis net 25 is substantially perpendicular with respect to
table top 30.
[0033] A perspective view of table top 30 is shown in FIG. 2. Table
top 30 includes a top surface 32 and a bottom surface 34. Top
surface 32 acts as a playing surface and bottom surface 34 contacts
base assembly 50 when table top 30 is placed atop base assembly 50.
Court markings such as a centerline 33 and/or side lines and end
lines may be included on top surface 32.
[0034] Table top 30 is formed from a first table section 38 and a
second table section 42. First table section 38 is separable with
respect to second table section 42 about a seam 44. In some
embodiments, seam 44 may be a joint that separates first table
section 38 and second table section 42. In some embodiments, the
inner edges of table sections 38, 42 do not touch each other. In
other embodiments, seam 44 may be a portion where first table
section 38 and second table 42 are abutting. Typically, table
tennis net 25 is positioned above seam 44 so that a table tennis
ball hit on the playing surface fainted by table top 30 does not
land on seam 44 during play.
[0035] In certain embodiments, one or more hinges 46 connect the
first table section 38 and the second table section 42 at the seam
44. As shown in FIG. 3, although not required, it is preferable
that the hinges 46 are located on the bottom surface 34 of table
top 30 so that hinges 46 are not exposed on the playing surface
formed by top surface 32 when table top 30 is in use. In some
embodiments, a single hinge 46, such as a piano hinge may extend
the entire length or substantially the entire length of seam 44. In
alternate embodiments, seam 44 is formed when the inner edges of
table sections 38, 42 are adjacent during play, but the table
sections 38, 42 may not be physically connected.
[0036] In the embodiment shown, the seam 44 is positioned about
halfway along the length of table top 30 so that first table
section 38 and second table section 42 are approximately the same
size. In other examples, table top 30 may include no seam 44 so
that the table top is not foldable and is merely removable from
base assembly 50.
[0037] In some embodiments, table top 30 follows the rules of the
International Federation of Table Tennis. The top surface 32 of
table top 30 is rectangular and is 274 cm (9 ft.) in length and
152.5 cm (5 ft.) in width. Table top 30 is supported so that top
surface 32 is 76 cm (2.5 ft.) above the floor. Top surface 32 is a
uniform, dark color with a matte finish. A white line extends along
each side along the length of top surface 32 and a white end line
extends along each side along the width of top surface 32. Table
sections 38, 42 are of equal size and separated by a vertical net
running along the width of table top 30. Table top 30 is formed
from any is material that yields a uniform bounce of 23 cm (81/4
in.) from any standard table tennis ball that is dropped from a
height of 30 cm (12 in.).
[0038] FIG. 4 illustrates base assembly 50 in an expanded
configuration. Base assembly 50 includes an arrangement with a
plurality of legs 52. The legs 52 are adjustably spaced relative to
each other so that base assembly 50 has a length, L, and a width,
W. Each leg 52 includes a telescoping pole 54 extending between a
table pad 70 and a floor pad 71. The table pad 70 is positioned at
an upper end of telescoping pole 54 and contacts the table top 30.
The floor pad 71 is positioned at a lower end of telescoping pole
54 and contacts the ground or a support surface when table top 30
is positioned on base assembly 50.
[0039] Each leg 52 is connected to an adjacent leg 52 by at least
one strut 65 that is angled between the legs 52. In some
embodiments, strut 65 is angled approximately 45 degrees with
respect to leg 52 in the expanded configuration. A first strut 65
extends from the table pad 70 of a first leg 52 to the floor pad 71
of the adjacent leg 52, for instance with one end of first strut 65
pivotally attached to the table pad 70 of a first leg and a second
end of the first strut pivotally attached to the floor pad 71 of a
second leg. A second strut 65 may extend from the floor pad 71 of
the first leg 52 to the table pad 70 of the adjacent leg 52 so that
the two struts 65 form a deformable X-shape between the adjacent
legs 52. In some embodiments, fewer struts 65 may be used so that
some of or all of the legs 52 are only connected to an adjacent leg
52 by one strut 65.
[0040] When base assembly 50 is not used to support table top 30,
base assembly 50 may be arranged in a collapsed position as shown
in FIG. 5. In the collapsed position, the distance between the legs
52 of base assembly 50 is greatly reduced so that the legs are
adjacent to each other and the base assembly 50 takes up less space
for easy storage. Struts 65 are pivoted with respect to legs 52
such that struts 65 are approaching vertical and are close to
parallel with regard to legs 52. As shown, the length, L, of base
assembly 50 in the collapsed configuration is less than the length,
L, of base assembly 50 in the expanded configuration. Likewise, the
width, W, of base assembly 50 in the collapsed configuration is
less than the width, W, of base assembly 50 in the expanded
configuration. In some embodiments, although not required, legs 52
may be in direct contact with adjacent legs when base assembly 50
is in the collapsed position.
[0041] An embodiment of a leg 52 of base assembly 50 is illustrated
in FIG. 6. As shown, leg 52 includes a telescoping pole 54
extending between a table pad 70 and a floor pad 71. Telescoping
pole 54 includes a male portion 56 that is slidable within a female
portion 58, allowing the height of leg 52 to be adjusted by sliding
male portion 56 with respect to female portion 58.
[0042] The table pad 70 is positioned at an upper end of
telescoping pole 54 and may include a table support surface 86.
Table support surface may include a non-slip material on the outer
surface of table pad 70. Table support surface 86 is arranged to
contact table top 30 when table top 30 is supported by base
assembly 50. When table top 30 is positioned on base assembly 50,
the bottom surface 34 of table top 30 rests on table support
surface 86 and table support surface 86 prevents table top 30 from
sliding with respect to leg 52.
[0043] A floor pad 71 is positioned at the opposite end of
telescoping pole 54 from the table pad 70. The floor pad 71 is
arranged to contact a support surface such as the ground or a floor
when base assembly 50 is in use. The outer surface of the floor pad
71 may include a floor contact surface 88 that is made from a
non-slip material. Floor contact surface 88 is in contact with the
ground or support surface and assists to provide stability to base
assembly 50 by preventing leg 52 from slipping on the ground when
the table tennis table 20 is in use.
[0044] FIG. 7 illustrates an example of a table pad 70. Although a
table pad 70 is shown in FIG. 7, it should be noted that a floor
pad 71 may have the same structure as table pad 70 and may be
arranged symmetrically with respect to table pad 70 on leg 52.
Table pad 70 includes a base 74 and a body portion 76 extending
vertically from base 74. Base 74 may include anchor openings 75
extending through base 74. Anchor openings 75 may receive an
anchoring mechanism for securing table pad 70 to the bottom surface
34 of table top 30. Similarly, anchor opening 75 may receive an
anchoring mechanism for securing a floor pad 71 to the ground or
other support surface. It is not required that anchoring mechanisms
be used with table pad 70. In some embodiments, table top 30 rests
on table pad 70 and is sufficiently secure without an anchoring
mechanism. Likewise, in some embodiments, floor pad 71 may rest on
a support surface without being anchored to the support surface
using an anchoring mechanism.
[0045] Body portion 76 defines a pole end cavity 78 that is sized
to allow an end of telescoping pole 54 of leg 52 to fit within pole
end cavity 78. Pole end cavity 78 is dimensioned to fittingly
receive an end of pole 54 of leg 52 and connect pole 54 to table
pad 70. Pole 54 may be snugly held within pole end cavity 78 using
a friction fit or may be kept within pole end cavity 78 using any
other suitable attachment method such as a fastener or
adhesive.
[0046] Body portion 76 also includes vertical and lateral flanges
80 that extend outward relative to pole end cavity 78. Each flange
80 defines a horizontal strut attachment opening 81 for to
receiving an attachment mechanism such as a screw or a bolt that
may serve as an axle. The attachment mechanism received in strut
attachment opening 81 may be used to rotatably attach a strut 65 to
table pad 70 so that strut attachment opening 81 defines a pivot
axis about which strut 65 is able to pivot with respect to leg 52.
Although each flange may include a strut attachment opening 81 for
attaching a strut 65, it is not required that each strut attachment
opening 81 is used when table pad 70 is included in base assembly
50. In some embodiments, table pad 70 may attach to only two struts
65 or only three struts 65. In the embodiment shown, there are four
flanges 80 each spaced at 90 degrees from an adjacent flange 80;
however in other embodiments there may be more or fewer flanges 80
as desired. Floor pad 71 has a corresponding structure to the
structure of table pad 70 described above.
[0047] Various views of an embodiment of the assembled table tennis
table 20 are shown in
[0048] FIGS. 1 and 8-11. In this embodiment, there are six legs 52
arranged in in two rows with three legs 52 in each row. This forms
a rectangular shaped base assembly 50 that is suited for supporting
a rectangular table top 30. The corner legs 52 are each attached to
the two adjacent legs 52 along the length and width of base
assembly 50 by struts 65. The legs 52 in the middle are each
attached to three adjacent legs 52 along the length and width of
base assembly 50 by struts 65. Although base assembly 50 is shown
having six legs 52, in other embodiments that may be less desired,
more or fewer legs 52 may be included in base assembly 50. For
example, the middle legs may be removed so that base assembly 50
has four legs with corresponding alterations to the table top. In
other examples, extra legs 52 may be added to provide greater
support, for example base assembly 50 could include eight legs.
[0049] In the embodiment shown in FIGS. 9-10, in the expanded
configuration, the legs 52 are positioned so that two of the legs
support the outer end of first table section 38 of table top 30 lo
and two of the legs 52 support the outer end of second table
section 42 of the table top 30. The middle two legs 52 support the
table top 30 along the seam 44. The table pads 70 of these middle
legs 52 straddle seam 44 and are in direct contact with both the
first table section 38 and the second table section 42.
[0050] In some embodiments, as shown in FIG. 12, table tennis table
20 may include an apron 90 that covers base assembly 50. Apron 90
hangs from table top 30 to hide base assembly 50 while also
preventing table tennis balls and other debris from becoming
trapped underneath table top 30. In some embodiments, apron 90 is
positioned between table top 30 and base assembly 50. For example,
apron 90 may be supported by table pads 70 and table top 30 is
positioned on top of apron 90 to clamp the apron in place. In some
embodiments, apron 90 hangs from a peripheral edge 35 of table top
30.
[0051] Apron 90 may be attached to table tennis table 20 using any
suitable method of attachment. As an example, apron 90 may be
attached to table tennis table 20 using screws, grommets, or snap
features. Other options such as hook and loop fasteners like
Velcro.RTM. may also be used. In some embodiments, apron 90 is
attached to table top 30, for example, on a side edge of table top
30 or on the bottom surface 34 of table top 30. In some
embodiments, apron 90 is attached to base assembly 50, such as to
table pad 70.
[0052] In some embodiments, apron 90 is easily changeable so one
apron 90 can be swapped for an apron 90 having a different color or
design. Apron 90 may be made from a variety of fabric options. For
example, apron 90 can be made from vinyl, nylon, cotton, spandex,
lycra, or any other suitable material. Apron 90 may also include
graphics or text such as team logos, advertising, or any other
desired visual indicia.
[0053] Typically, when table tennis table 20 is not in use, it may
be stored in the collapsed lo configuration. In the collapsed
configuration, table top 30 is folded in half as shown in FIG. 3
and base assembly 50 is configured as shown in FIG. 5 to reduce the
size of table top 30 and base assembly 50.
[0054] When table tennis table 20 is desired to be used, table
tennis table 20 is converted from the collapsed configuration into
the expanded configuration. To convert table tennis table 20 to the
expanded configuration, the legs 52 of base assembly 50 are pulled
away from each other. In the collapsed configuration as illustrated
in FIG. 13, the struts 65 extending between adjacent legs 52
approach being positioned vertically, so that the struts are close
to parallel with respect to telescoping pole 54 of each leg 52 to
which strut 65 is attached. However, as the legs 52 are pulled
apart from each other, the struts 65 pivot with respect to legs 52
so that each strut 65 is positioned at a significantly oblique
angle with respect to each leg 52 to which the strut 65 is attached
(see FIG. 14). As an example, a significantly oblique angle is
considered to be an angle between 15 and 75 degrees. In some
embodiments, the oblique angle formed between strut 65 and leg 52
in the expanded configuration may be approximately 45 degrees.
[0055] As shown in FIGS. 13-14, the length A, of a strut 65 is
fixed yet struts 65 are pivotable. Therefore, the vertical height,
H.sub.C, a strut 65 spans when base assembly is in the collapsed
configuration is greater than the vertical height, H.sub.E, strut
65 spans when base assembly 50 is in the expanded configuration. As
the vertical height span of strut 65 decreases from H.sub.C to
H.sub.E, the angle, B, between strut 65 and leg 52 is
increased.
[0056] To accommodate the changing vertical height span of strut
65, the male portion 56 of telescoping pole 54 telescopes within
the female portion 58 of telescoping pole 54 to decrease the length
of leg 52 when legs 52 are pulled away from each other into the
expanded configuration. Likewise, as base assembly 50 is changed
from the expanded configuration to the collapsed configuration,
male portion 56 of telescoping pole 54 extends from female portion
58 of telescoping pole 54 to increase the length of leg 52.
[0057] The expansion of base assembly 50 is limited by the minimum
length of legs 52 as expansion of base assembly 50 may continue
until the length of legs 52 may no longer decrease. The minimum
length of legs 52, and thus the table height, is determined by the
movement of male portion 56 of telescoping pole 54 within female
portion 58. Once the lower end of male portion 56 reaches the lower
end of female portion 58, it will rest against floor pad 71 or the
lower end of female portion 58, so that male portion 56 may not
slide any further within female portion 58. Once male portion 56
can no longer slide within female portion 58, a minimum height is
reached. In this configuration, the weight from table top 30 may be
carried solely by male portion 56. If female portion 58 has an open
lower end, none of the weight of table top 30 is supported by
female portion 58.
[0058] Once base assembly is arranged in the expanded
configuration, table top 30 is unfolded so that first table section
38 and second table section 42 lie within the same plane. Table top
30 is then placed on top of base assembly 50 so that the bottom
surface 34 of table top 30 contacts table pads 70 of the legs 52 of
base assembly 50. The table pads 70 of base assembly 50 provide
support points for table top 30. A table tennis net 25 may be
attached or mounted to table top 30 and table tennis table 20 may
be used for table tennis games or practice.
[0059] Table tennis table 20 is collapsible into a collapsed state
for storage or transport by reversing the process described above.
The table top 30 is removed from the top of base assembly 50. Table
top 30 may then be folded in half by folding or separating first
table section 38 with respect to second table section 42 at the
seam 44. Base assembly 50 is then moved from the expanded
configuration to a collapsed configuration by moving the legs 52
closer to each other and causing struts 65 to pivot into an
orientation in which the struts are substantially parallel to legs
52.
[0060] A collapsible table tennis table kit 100 is illustrated in
FIG. 15. Kit 100 includes a table top 30 that includes a first
table section and a second table section and a table tennis net 25.
The second table section of table top 30 is connected to the first
table section by one or more hinges and is foldable with respect to
the first table section about the hinges.
[0061] Kit 100 also includes a base assembly 50, such as base
assembly 50 shown in FIG. 4. In some embodiments, kit 100 also may
include at least one table tennis paddle 105 and one or more table
tennis balls 110. Kit 100 may also include an apron 90.
[0062] While the invention has been illustrated and described in
detail in the drawings and foregoing description, the same is to be
considered as illustrative and not restrictive in character, it
being understood that only the preferred embodiment has been shown
and described and that all changes, equivalents, and modifications
