According to one aspect of the invention there is provided a martial arts equipment device comprises;
a frame;
the frame having a horizontal base for resting on the ground and a pair of vertical posts upstanding from the base;
the vertical posts having a slidable member;
the slidable member being arranged for holding one or more parallel boards being placed side by side in a vertical orientation for breaking;
wherein the frame includes a collapsible inclined rear posts which supports the vertical posts;
the collapsible inclined rear posts being mounted on a hinge;
the hinge being located on the horizontal base arranged to support the collapsible inclined rear post;
the vertical post being collapsible and mounted on a second hinge;
the second hinge being located on the horizontal base for supporting the vertical post.
Preferably the frame includes a wheel for movement across the ground.
Preferably the frame includes a plurality of cross bars to support the vertical post, the horizontal base and the collapsible inclined rear post, the cross bars being mounted on the vertical post, the horizontal base and the collapsible inclined rear post such that the cross bars are perpendicular to the vertical post, the horizontal base and the collapsible inclined rear post.
According to a second aspect of the invention there is provided a martial arts equipment device comprising;
a frame;
the frame having a horizontal base for resting on the ground and a pair of vertical posts upstanding from the base;
the vertical posts having a slidable member;
the slidable member being arranged for holding one or more parallel boards placed side by side in a vertical orientation for breaking;
wherein the slideable member has a member for supporting one or more parallel boards placed side by side in a vertical orientation for breaking;

the rigid arms co-operating with the pivotal arms to clasp the boards;
an abutment being fixed to the slidable member and positioned to break the boards;
the abutment being located below the pivotal arms for increased support.
Preferably the extending members have a cross member in which forms a lip that is formed to hold the boards in position;
Preferably the extending members are spring mounted to allow one or more boards to be placed on the slidable member;
Preferably the pivotal arms are mounted on a hinge in which is located on the slidable member so that the pivotal arms can be adjusted to allow boards to be inserted onto the rigid arms and held by the pivotal support arms.
