Description
RUGBY SCRUMMAGING TRAINING APPARATUS
Field of the Invention
This invention relates to a Rugby scrummaging training apparatus.
Background of the Invention
Rugby football incorporates scrummaging or “scrums” as a part of gameplay.
A scrum requires players from each team to engage so that the player’s
heads ock with those of the opposing team. To t play from a
stoppage the ball is played between the feet of the opposing players. The
players then push against each other to retrieve the ball for their teammates
using their feet.
A variety of machines and apparatus have been developed to assist players
practicing their scrummaging technique and to develop strength for
scrummaging play. These existing machines generally consist of a series of
pads ted to a frame mounted to a sled or a similar form of carriage.
Players engage with the pads and push against the frame with the weight of
the sled acting as resistance to their attempts to move forward. Some more
sophisticated forms of scrummaging es also incorporate hydraulic
rams or springs which are used to resist the forward motion of the players
pushing against the pads of the machine.
These existing scrum machines are relatively simple devices which do not
accurately te aging play. In practice players experience a
range of forces coming from different directions during aging — not
just a single force originating from directly in front of the player.
For example, a team may deliberately apply a lateral twisting force to the
scrum to upset the play of an opposing team with the ball feed to the scrum.
Furthermore the opposing forward forces generated by the scrum can have a
ilising effect and result in upward or downward res which must
be resisted if the scrum is not to collapse.
Existing scrum machines are also limited in terms of their performance or
the scrummaging behaviors they can simulate. Simple sled based machines
present less resistance to players once in motion, while scrum machines
incorporating s or hydraulic rams present varying levels of resistance
or active rds pushing force when compressed or activated.
Prior art scrum machines are also large heavy pieces of equipment which are
difficult to transport and store. Furthermore, due to the heavy nature of the
uction materials used these existing aging machines are also
relatively expensive to construct.
It would therefore be of advantage to have improvements over the prior art
which addressed the above issues or at least provided the public with an
alternative choice. In particular, it would be of advantage to have a rugby
scrummaging training apparatus which provides a better simulation of
scrummaging gameplay. An apparatus which could be used effectively by a
single player in isolation or a group of players er would also be of
advantage. An improved scrummaging training apparatus which has a
portable character and which is ffective to manufacture would also be
of advantage.

the engagement member of the second apparatus.
The t invention is arranged to provide a rugby scrummaging ng
apparatus, and in some preferred embodiments a rugby scrummaging
training device formed from two or potentially more of such tus.
A training apparatus provided by the ion es at least one
engagement member. An engagement member may in some ces be
arranged or configured to mount one or more pads to the apparatus,
ng a user to engage with and push against the apparatus in a r
way to which prior art scrum machines are used. Alternatively in other
embodiments where a training device is provided an engagement member
may not necessarily mount a pad or pads, but instead can be fixed to the
3O base member or members of a further training apparatus.
In a preferred embodiment a training apparatus may include two or
potentially more engagement members orientated substantially parallel to
one another and connected together to form an engagement frame. In such
embodiments one or more intermediate g bars may be deployed
between the engagement members and can be used to fix the distance
between these members. Those skilled in the art will appreciate that in some
embodiments the ion may be implemented using a single engagement
member of an appropriate size and shape - or alternatively using a number
of smaller engagement members used to define an engagement frame.
A ng apparatus ed by the invention includes at least one base
member. In some embodiments a base member may be configured to
connect the apparatus to a stationary t such as — for example — the
wall of a building or the rear of a vehicle by way of towing hitch. Preferably
the stationary element involved may be large and/or heavy. In such
embodiments this connection allows the apparatus to be deployed and used
effectively in a range of environments. Alternatively in other embodiments
where a training device is provided by the invention a base member may be
fixed to the engagement member or members of a r training
apparatus.
In a preferred embodiment a training apparatus may include two or
potentially more base members orientated substantially parallel to one
another and connected together to form a base frame. In such embodiments
one or more intermediate spacing bars may be deployed between the base
s and can be used to fix the distance between these members.
Those skilled in the art will appreciate that in some embodiments the
invention may be implemented by a single base member of an appropriate
size and shape or alternatively a number of smaller base members used to
define a base frame.
Reference throughout this specification is made to various components of
the ion being connected together — be it by pivoting connections, fixed
connections and/or translating connections. Those skilled in the art will
appreciate that these connection references include both a direct contact
3O between the components, in on to indirect connections ented by
intermediary ents. For example, in some embodiments a variable
length drive element may be connected to an engagement member or base
member through an intermediary spacing bar connected to the relevant
. Furthermore in various embodiments ating connections
between linking members and engagement or base s may be made
through an intermediary carriage element. In yet other embodiments base
members may again be connected to building, vehicles or other engagement
members by intermediary elements.
A ng apparatus provided by the invention also includes at least one
g member. A linking member is connected through at least two pivots
to both an engagement member and a base member. Preferably a g
member may be formed from a substantially straight length of material with
its ends having a pivoting connection to an ment member and a base
member.
A linking member incorporated into a training tus also includes one
ating connection which is associated with or connected to either a base
member or an engagement member. A translating connection is configured
to move parallel to the longitudinal axis of the member it is connected to.
For e in some embodiments a translating connection may be provided
by a carriage element configured to travel along a locating guide such as a
track or a channel attached to or formed in at least a section of the length of
a base member or engagement member. One end of a linking member can
be connected to this carriage by way of a pivot to provide a pivoting
translating connection.
Providing linking members with a translating connection allows the
associated training tus to be expanded or compressed when used.
This system of pivoting and translating tions are provided to allow an
engagement member to move towards and away from a base member, in
addition to allowing one end of the engagement member to tilt inwards
towards the base member while its opposite end stays approximately in the
same place.
3O A training apparatus provided in accordance with the present invention also
includes at least one variable length drive element. The length of this drive
element can be expanded or contracted to impart motion to the translating
connections of the linking member or members. A drive or power system
associated with a drive element can therefore e the energy required to
resist the efforts of a user employing the invention during aging
training.
Those skilled in the art will appreciate that the ends of a drive element may
be connected to various components of a training apparatus to achieve the
above results. For example, in one embodiment one end of a drive element
may be fixed to a base or an engagement member, with its opposite end
connected to the ating or moving portion of a translating connection
engaged with the same base or engagement member. In yet another
embodiment one end of a drive element can include a pivoting connection to
a base member and the opposite end of the drive element can include a
pivoting connection to an engagement member.
In a red embodiment the t invention may include a
microprocessor control element configured to control the activation of said at
least one drive element. This control t can preferably be used to
control both the tion of a drive element in addition to the degree to
which the drive element is extended or the degree of force applied by the
drive element. In embodiments where the invention includes a plurality of
drive ts a single microprocessor control element may also be used to
independently control the tion and performance of each of these drive
elements.
In a preferred embodiment a variable length drive element may be formed
by a pneumatic ram. In these embodiments an air pump may be used to
pressurise and power this form of ram, working to extend the length of the
ram to push back against forces applied by a user. Those skilled in the art
will iate that these types of rams may be provided with a pressure
release value, where the r value of this valve can be adjusted to
control the performance of the apparatus. In various ments players
may push against — or be pushed backwards — by a ram concurrently being
supplied with pressurised air. In other instances a ram may not necessarily
3O be concurrently supplied with pressurised air, with the ram’s pressure
release valve being set to a re value which must be overcome by
players as part of a training exercise.
In a red embodiment a training apparatus provided by the ion
may include a number of drive elements deployed along the length of its
base and engagement members. For example in one further preferred
embodiment a training apparatus may include two drive elements, each
being deployed adjacent to either end of the base and engagement members
provided. Each of these drive elements can in combination resist the forward
motion of a user pushing against the engagement member. Furthermore
each of these drive elements may be controlled or powered independently to
present varying degrees of resistance to the user at either end of the
engagement member.
Reference in general throughout this specification will also be made to the
invention incorporating a number of variable length drive elements formed
by pneumatic rams. r those skilled in the art will appreciate that
other configurations or arrangements of the ion are envisioned and
reference to the above should in no way be seen as limiting.
In a preferred embodiment a drive ram provided with a ng tus
may also include a re release valve operated or controlled by a
microprocessor control element. These components can provide an operator
of the apparatus with c control of the resistance forces applied by
each drive ram, and ore the resistance forces experienced by a user of
the invention. For example in some embodiments a microprocessor-based
control element may be able to set the air pressure values which will trigger
opening of the associated pressure release valve.
This control system can therefore provide a constant level of resistance to
the efforts of the user, or can modify the resistance experienced by a user at
various portions or ends of an engagement . For e, the
driving pressure of a ram at one end of the engagement member may be
reduced while increasing pressure at the opposite end to simulate the tilting
or wheeling of a scrum by an opposing team.
3O As indicated above the invention may be used to implement a rugby
scrummaging training apparatus in addition to a rugby scrummaging training
device formed from two such apparatus. Such a device may be provided by
connecting together two the training apparatus referenced above with the
ment member or members of the second apparatus g any pads.
Preferably a training device may be provided by two training apparatus
connected together with a substantially dicular orientation. In such
embodiments one apparatus may be used to simulate lateral turning of a
scrum, while the other may simulate vertical tilting forces experienced within
a scrum. This arrangement of a training device therefore provides a
relatively accurate simulation of the forces experienced by a player in a real
scrum.
The present invention may provide many potential advantages over the prior
A training tus or training device implemented by the ion can be
provided with a lightweight and portable character. The invention does not
require a large heavy sled as is the case with the prior art, and can simply
be mounted to any ient large static element or surface. Furthermore
when not in use the engagement and base members can be sed
towards one another to allow for ease of storage and transportation.
The invention may also provide a dynamic resistance facility capable of
simulating the actual forces experienced in a scrum. The invention can be
used to apply a constant resistance force, or may be dynamically
igured to stimulate scrum wheeling or upwards and downwards scrum
forces.

Further aspects of the invention will become apparent from the following
ption of the invention which is given by way of example only of
particular ments.
Best modes for carrying out the invention
Figures 1 to 3 show a number of views of a rugby scrummaging training
apparatus as provided in accordance with a preferred embodiment. In the
embodiment shown the apparatus is configured for use by three players at
the same time.
The apparatus 1 includes a pair of parallel aligned engagement members 2
which are connected together by a set of spacing bars 15 to form an
engagement frame. Each of these engagement members has a U-shaped
profile which defines a channel as discussed further below. This engagement
frame is used to mount a set of pads for a user to push comfortably against.
Pad ng brackets 4 can be connected at various points to the
engagement frame using a series of connection holes 5.
Also provided are a pair of parallel aligned base members 6 which are
connected together by a set of spacing bars 15 to form a base frame. In use
the base frame can be bolted to a wall of a structure (not shown).
Each engagement member is connected to a corresponding base member by
two linking members 7 d at either end of the base and engagement
members. Each linking member has a pivoting connection 8 to the base
member and a pivoting connection 8 to the engagement member.
Each linking member is connected to an engagement member by a
translating connection 9. This translating connection includes a carriage
arranged to run inside a channel or track formed in the U- shaped
engagement member, with the linking member connected to the carriage
using a pivot. The travel of the carriage along the track is terminated by a
stop bolt 10.
These translating connections allow one end of each linking member to move
parallel to and along the longitudinal axis of the engagement member,
compressing or expanding the form of the training apparatus when used.
Furthermore, a force applied to one end only of the engagement member
directed towards the base member will reduce that ends distance to the base
member while maintaining the distance between the opposite end of the
engagement member and the base member.
The training apparatus also includes two variable length drive elements
formed in this ment by pneumatic drive rams 11. The rams 11 are
powered by a compressor 12 which es high pressure air by way of a
set of on/off switches 13 and pressure e valves 14. The trigger
pressure value of each release valve 14 is dynamically controlled by a
microprocessor controller (not shown) which can receive input commands
from a user to change the behaviour of the training apparatus.
A drive ram 11 is provided at each end of the engagement and base ,
with the ends of the ram being connected with pivoting connections 8. Each
ram is arranged to move the translating connection of the linking member in
a direction parallel to the longitudinal axis of the engagement member. This
motion applies a force which increases or ins the ce between
the engagement frame and the base frame and which resists forces applied
by the user to urge the engagement frame towards the base frame.
3O Each pneumatic drive ram includes a re release valve 14 linked to a
control element (not shown). These pressure release valves and control
element are configured to dynamically adjust the force applied by the drive
ram to increase or maintain the ce between the base member and
engagement member.
The control element can ore be used to apply a constant resistance
force to the efforts of the user, or may dynamically adjust the force applied
to each end of the ment frame. The application of unequal pressures
to the rams of the apparatus can therefore be used to simulate turning of
the scrum, or vertical forces experienced within the scrum.
Figures 4 through 6 shows a rugby aging training device formed in
accordance with an alternative embodiment to that shown in relation to
figures 1 to 3. In the ment of figures 4-6 a training device is provided
for use by a single .
A similar arrangement is provided in this ment to that of the three
player device, other that the engagement members and base members
having shorter lengths, and the device including a single linking member 7
and pneumatic ram 11 only. Again the ram is arranged to move the
translating connection of the linking member in a direction parallel to the
longitudinal axis of the engagement member. This motion again applies a
force which increases or maintains the distance between the engagement
frame and the base frame and which s forces d by the user to
urge the engagement frame towards the base frame.
Figure 7a and 7b show a perspective views of a training apparatus as
provided in accordance with an alternative embodiment to that of figures 1
to 6. Figure 7a shows the apparatus 101 when placed in an extended
configuration, while shows the apparatus when placed in a compressed
configuration.
The views provided by figures 7a and 7b show a simplified version of the
apparatus with it’s two variable length drive elements not shown. In this
embodiment a drive t is again formed by a pneumatic ram, with rams
being provided between each set of engagement members 102 and base
3O members 106 running from the middle of the base members to the outer
ends of the ment members.
Again a set of linking members 107 are connected via pivoting connections
108 to the base members 106. The opposite ends of the linking members
are connected by translating connections 109 through to the engagement
members 102.
Each ating connection 109 is formed by a ring shaped carriage 116
which runs over a cylindrical track 117. The freedom of movement provided
to the apparatus by these translating connections 109 is shown by the
contrasting extended and compressed configurations of figures 7a and 7b
tively. Players pushing against the extended ment members
can move the apparatus into the compressed configuration of figure 7b
