BACKGROUND
[0002] Trampolines are commonly used in outdoor and indoor activities. Trampolines comprise
a frame structure and a mat connected to the frame structure with stretching elements
such as springs or similar. The frame structure comprises transverse and horizontal
tubes. Trampoline activities include playing basketball. A basketball hoop designed
for trampolines include traditional basketball hoop parts such as a rim, a backboard
and arrangements for attaching the basketball hoop to the frame structure, which is
in this case the trampoline frame structure. However, installing a basketball hoop
onto the trampoline may lead to accidents when the trampoline users collide with the
hoop. This is because the users can injure themselves by colliding with the hoop during
the upward bounce.
[0003] Patent publication
US7429224 discloses a basketball hoop and a backboard for a trampoline. It provides a basketball
hoop assembly that absorb energy to avoid injury to players. This is implemented by
having two pairs of springs that are deployed in such a way that the rim assembly
can flex in the vertical direction, absorbing the collision energy. However, this
kind of spring arrangement is hard to construct, and it has many parts that can break
and thus render the whole hoop construction unusable. Furthermore, having this many
springs that extend and contract can cause irritating sounds when the basketball hoop
assembly is in active use.
BRIEF DESCRIPTION
[0004] The object of the invention is a solution that can significantly reduce the disadvantages
and drawbacks of the prior art. In particular, the object of the invention is a solution
where a basketball hoop structure is provided that improves safety and still is silent
and easy to construct.
[0005] The objects of the invention are attained with a basketball hoop structure that is
characterised by what is stated in the independent patent claim. Some advantageous
embodiments of the invention are disclosed in the dependent claims.
[0006] The invention is a basketball hoop structure that is configured to be fixed onto
a trampoline. The basketball hoop structure comprises a frame, a rim and a backboard,
and the rim has a horizontal position and is connected to the frame and is vertically
pivotable from the horizontal position. The rim comprises a connection arrangement
having a first branch and a second branch for connecting the rim to the frame. The
basketball hoop structure further comprises a first elastic arrangement and a second
elastic arrangement, and parts of the first branch and the second branch are positioned
between said elastic arrangements. The elastic arrangements dampen the movements of
the rim and return it to the original position.
[0007] When reference is made in the text to the upper or the lower parts or respective
directions such as down or up, a situation is described in which the basketball hoop
structure according to the invention is in use, i.e. attached to the trampoline. Also,
when reference is made to the vertical or horizontal directions or surfaces, the basketball
hoop structure is placed similarly.
[0008] In one embodiment of the invention is a basketball hoop structure for a trampoline.
The basketball hoop structure comprises a frame, a rim and a backboard, and the rim
has a horizontal position and is connected to the frame in such a way that the rim
is vertically pivotable from the horizontal position and the rim is padded at least
partially with a layer of elastic material. The frame is configured to be affixed
to the trampoline. In one advantageous embodiment of the invention, the rim comprises
a connection arrangement having a first branch and a second branch for connecting
the rim to the frame. The frame comprises a support structure having at least a horizontal
lower surface, and the basketball hoop structure further comprises two elastic arrangements:
a first elastic arrangement and a second elastic arrangement, and parts of the first
branch and the second branch are positioned between the first elastic arrangement
and a second elastic arrangement, and the first elastic arrangement is positioned
on the lower surface.
[0009] In one embodiment of the basketball hoop structure, the layer of elastic padding
material on the rim surrounds the rim in such a way that the part of the rim between
the first branch and the second branch is uncovered at least partly.
[0010] In a second embodiment of the basketball hoop structure, the basketball hoop structure
comprises an attaching arrangement for attaching the first elastic arrangement and
the second elastic arrangement to each other and onto the frame. In a third embodiment
of the basketball hoop structure, the attaching arrangement penetrates at least the
first elastic arrangement, the second elastic arrangement and the lower surface. In
a fourth embodiment of the basketball hoop structure, the attaching arrangement is
a bolt-like structure and is positioned between the first branch and the second branch.
[0011] This feature improves the elasticity and makes construction easier and keeps the
elastic arrangement firmly in place.
[0012] In a fifth embodiment of the basketball hoop structure, the elastic arrangements
are made of rubber or of another material having properties similar to rubber. The
inventors have discovered that the durability and elasticity of rubber are very suitable
for the basketball hoop structure according to the invention.
[0013] In a sixth embodiment of the basketball hoop structure, the elastic arrangements
are continuous objects, and the ends of the elastic arrangements extend over the first
branch and the second branch. This feature improves the elasticity and makes construction
easier and keeps the elastic arrangement firmly in place. Also, the durability of
the structure improves in this kind of embodiment.
[0014] In a seventh embodiment of the basketball hoop structure, the connection arrangement
is configured in such a way that the directions of the first branch and the second
branch on the elastic arrangements are dissimilar. This feature improves the bouncing
effect of the rim without having to widen the elastic arrangement, because longer
sections of the branches touch the elastic arrangement compared to a situation where
the branch slot is perpendicular to the elastic arrangement.
[0015] In an eighth embodiment of the basketball hoop structure, the elastic arrangements
have front sides and back sides, and the front side of the elastic arrangement is
toward the rim and the back side is of the elastic arrangement is on the opposing
side in relation to the front side, and the distance between the first branch and
the second branch is larger at the front side than at the back side. This feature
makes it possible to implement more compact connection arrangements and basketball
hoop structures.
[0016] In a ninth embodiment of the basketball hoop structure, the connection arrangement
is a loop, i.e. the first branch and the second branch are interconnected. This feature
improves the durability and safety of the connection arrangement.
[0017] In a tenth embodiment of the basketball hoop structure, the support structure comprises
an upper surface and the elastic arrangements are between the upper surface and the
lower surface.
[0018] In an eleventh embodiment of the basketball hoop structure, the support structure
is at least partly behind the backboard. In a twelfth embodiment of the basketball
hoop structure, there is a hole in the lower part of the backboard, and the lower
surface is configured to fit into said hole. In a thirteenth embodiment of the basketball
hoop structure, the front surface of the lower surface is approximately at the same
level as the backboard. In a fourteenth embodiment of the basketball hoop structure,
the connection arrangement connections to the frame are positioned behind the backboard.
These features make the basketball hoop structure more compact and thus safer.
[0019] It is an advantage of the invention that it provides a basketball hoop structure
for a trampoline that improves safety and is easy to manufacture.
[0020] One advantage of the invention is that it is relatively silent.
[0021] It is a further advantage of the invention that it can be easily optimized for different
kinds of trampolines.

DETAILED DESCRIPTIONS OF THE FIGURES
[0023] The embodiments in the following description are given as examples only and someone
skilled in the art can carry out the basic idea of the invention also in some other
way than what is described in the description. Though the description may refer to
a certain embodiment or embodiments in several places, this does not mean that the
reference would be directed towards only one described embodiment or that the described
characteristic would be usable only in one described embodiment. The individual characteristics
of two or more embodiments may be combined and new embodiments of the invention may
thus be provided.
[0024] Figures 1 shows an embodiment of a basketball hoop structure 100 that is fixed to
a trampoline frame 112 with a fixing arrangement. The basketball hoop structure comprises
a frame 101, a rim 102, a backboard 103, a connection arrangement 113, a support structure
107 and two elastic arrangements (not visible in Figure 1): a first elastic arrangement
and a second elastic arrangement.
[0025] The rim 102 is a metal structure with an attached net affixed onto a backboard. The
structure is at least partially circular; it is a bent rod or a similar construction.
The rim of the trampoline basketball hoop does not necessarily require a net and in
some embodiments is the net is omitted for safety reasons. The rim 102 is padded at
least partially with a layer of elastic material 104.
[0026] The frame 101 connects the rim 102 and the backboard 103 and keeps the whole basketball
hoop structure 100 together. Also, the frame provides structural integrity for the
basketball hoop structure. The connection arrangement 113 comprises a first branch
and a second branch (not visible in Figure 1) for connecting the rim to the frame.
The branches comprise first ends and second ends. The first ends of the branches are
fixed to the rim and the second ends are connected to the frame. The connection between
the branches and the frame is such that the rim pivots in the vertical direction and
the pivot point (the point that forms its centre of rotation) is the connection point
between the branches and the frame. In some embodiments the rim is not a continuous
circle but the rod, which forms the rim, is bent toward the branches, and there is
a gap in the rim between first ends of the branches.
[0027] The support structure 107 serves to support the elastic arrangements and keeps them
in predetermined positions in relation to the frame. Some parts of the first branch
and the second branch are positioned between the first elastic arrangement and a second
elastic arrangement. The first elastic arrangement is resting on the bottom part of
the support structure. When a vertical force, acting upward or downward, is affecting
the rim in its horizontal position, the rim pivots toward the direction of the force.
The elastic arrangements deform and resist the movement and then regain their original
form and return the rim to its horizontal position.
[0028] Figure 2 shows a detail of the basketball hoop structure 100 presented in Figure
1 as seen from above the level of the rim. The basketball hoop structure comprises
the frame 101, the rim 102, the backboard 103, the connection arrangement 113, the
support structure 107 and two elastic arrangements: a first elastic arrangement 109
and a second elastic arrangement 110. The rim is is padded with a layer of elastic
material 104 for protective purposes. The connection arrangement comprises the first
branch 105 and the second branch 106. The branches have first ends and second ends.
The first ends are connected to the rim and the second ends are connected in an adjustable
way to the frame. In this embodiment the rod forming the rim is bent toward the branches.
Between the branches there is a gap in the rim. The layer of elastic material leaves
the gap uncovered. In this embodiment, the branches are parallel and perpendicular
to the longitudinal axis of the elastic arrangement. In some embodiments, the directions
of the first branch and the second branch on the elastic arrangements are dissimilar.
In that case, the lengths of the branches between the elastic arrangements are longer
than in the situation where the branches are perpendicular to the longitudinal axis
of the elastic arrangement. In some embodiments, the branches converge when they approach
the backboard 103. In some embodiments, the second ends of the branches are interconnected,
and this loop is placed into a tunnel or a groove when connected to the frame.
[0029] The support structure 107 serves to support and hold the first elastic arrangement
109 and the second elastic arrangement 110 and the branches between them. The support
structure comprises at least a lower surface 108 and an upper surface. Said surfaces
are horizontal plate-like structures or extensions and the distance between them is
adjustable. Advantageously, the upper surface is removable for maintenance purposes.
The basketball hoop structure 100 comprises an attaching arrangement 115 for attaching
the first elastic arrangement and the second elastic arrangement to each other and
onto the frame 101 and more particularly to the support structure. The attaching arrangement
is a vertical bolt-like structure and is positioned between the first branch and the
second branch. The attaching arrangement penetrates at least the first elastic arrangement,
the second elastic arrangement and the lower surface. In this embodiment, the attaching
arrangement presses the lower surface against the upper surface, sandwiching the elastic
arrangements between the two.
[0030] On the lower part of the backboard 103 is a hole 115. The support structure fits
at least partly inside said hole. The frame 101 is positioned at least partly behind
the backboard. The lower surface 108 is connected to the frame 101. Fitting the support
structure at least partly inside the hole makes it possible to move the rim closer
to the backboard and thus secure the moving parts in order to minimise the possibility
of accidents.
[0031] The first elastic arrangement 109 and the second elastic arrangement 110 have first
ends and second ends, front sides and back sides, and upper sides and lower sides.
The front side of the elastic arrangement is positioned toward the rim 102 and its
back side is positioned toward the backboard 103 or toward the same level as the backboard.
The elastic arrangements are both continuous objects that extend over the first branch
105 and the second branch 106, i.e. the first branch and the second branch are between
the ends of the elastic arrangements. The first elastic arrangement is positioned
on the lower surface 108. The second elastic arrangement is positioned on the first
elastic arrangement. The first branch and the second branch are positioned between
the upper side of the first elastic arrangement and the lower side of the second elastic
arrangement. In some embodiments, the distance between the first branch and the second
branch is larger at the front sides than at the back sides. The elastic arrangements
are made of rubber or of another material having properties similar to rubber. Rubber
maintains its properties even if the basketball structure is extensively used. The
structure of the support structure 107 makes it possible to change the elastic arrangement
if required.
[0032] Figure 3 shows a detail of the basketball hoop structure 100 presented in Figure
1 as seen from somewhat below the level of the rim 102 when it is in its horizontal
position. The basketball hoop structure comprises the frame 101, the rim 102, the
backboard 103, the support structure 107, the first elastic arrangement 109, the second
elastic arrangement 110, the first branch 105 and the second branch 106. The frame
comprises a horizontal beam 116 at the lower part of the basketball hoop structure.
The horizontal beam forms the bottom edge of the frame.
[0033] The support structure 107 further comprises an attachment plate 117. The attachment
plate is fixed onto the horizontal beam 116. At least some of the parts of the support
structure that support the elastic arrangements are fixed onto the attachment plate.
In this example, the lower surface (not marked in Figure 2) is fixed onto the attachment
plate. The lower surface forms a shelf-like structure and the first elastic arrangement
109 is positioned on the lower surface. On the lower part of the backboard 103 there
is the hole 115. In this embodiment, the hole is positioned in such a way that it
is open toward the bottom edge of the backboard, i.e. the bottom edge has a curvature
that forms the hole. The attachment plate is positioned partly inside the hole and
the lower surface extends horizontally from one side of the hole to the other side
of the hole. The attaching arrangement 111 extends from the lower surface to the upper
surface (not marked in Figure 3) and joins said surfaces together and at the same
time, joins the elastic arrangements and branches between the elastic arrangements
as well. The attaching plate makes fixing the support structure onto the frame easier
and it provides more alternative positions for the rim. In some embodiments, the connection
arrangement (not marked in Figure 3) is configured to be fixed onto the frame with
the attaching plate.
[0034] Figure 4 shows an exploded view of the basketball hoop structure 100 as presented
in Figure 1. The basketball hoop structure comprises the frame 101, the rim 102, the
backboard 103, the support structure 107, the first elastic arrangement 109, the second
arrangement 110, the hole 115 and the branches (not shown it Figure 4) fixed onto
the rim from one end and attached in a vertically adjustable way onto the frame from
the other end. The frame is attached onto the trampoline frame 112. The trampoline
frame comprises at least a horizontal tube, and the basketball hoop structure is attached
to it. Advantageously, the attachment of the basketball hoop structure to the trampoline
frame is implemented in such a way that the bottom edge of the frame is positioned
below the horizontal tube. This arrangement prevents cracks from forming between the
trampoline frame and the basketball hoop structure, in which the user's fingers can
get stuck, thus increasing safety.
