Dismountable gymnastic device formed as a horizontal bar having a bayonet-closure feature

Claim 2

A dismountable gymnastic device formed as a horizontal bar, comprising a bow including a horizontal bar, a holding means, a central plug pin disposed on said bow and entering into said holding means in a vertical plug connection, as well as being coordinated to a bayonet-closure connection, and said bayonetclosure connection including escape recesses extending in upward direction, a bayonet-closure pin, a housing for said holding means, an axial-pressure bearing disposed in said housing and including an upper ring having an opening, and said bayonetclosure pin crossing said opening of said upper ring.

Claim 3

A dismountable gymnastic device formed as a horizontal bar, comprising a bow including a horizontal bar, a holding means, a central plug pin disposed on said bow and entering into said holding means in a vertical plug connection, as well as being coordinated to a bayonet-closure connection, said bayonet-closure connection including escape recesses extending in upward direction a bayonet-closure pin, said holding means including, a housing, a braking ring rigidly mounted in said housing, an upper bearing ring having an axial opening disposed underneath said braking ring rotatably and axially displaceably mounted in said housing and abutting said braking ring in an unloaded condition of said bow, and said upper bearing ring prevented from rotatable movement when abutting said braking ring, a compressible lower ring abuttingly disposed underneath said upper bearing ring, said upper bearing ring displaced axially downwardly spaced away from said braking ring in a loaded condition of said bow compressing said lower ring and permitting free rotation of said upper bearing ring, and said bayonet-closure pin crossing said axial opening of said upper bearing ring.

Claim 4

A dismountable gymnastic device formed as a horizontal bar, comprising a bow including a horizontal bar, a holding means, a central plug pin disposed on said bow and entering into said holding means in a vertical plug connection, as well as being coordinated to a bayonet-closure connection, said bayonet-closure connection including escape recesses extending in upward direction a bayonet-closure pin, said holding means including, a housing, a braking ring rigidly mounted in said housing, an upper bearing ring having an axial opening disposed underneath said braking ring rotatably and axially displaceably mounted in said housing and abutting said braking ring in an unloaded condition of said bow, and said upper bearing ring prevented from rotatable movement when abutting said braking ring, a compressible lower ring abuttingly disposed underneath said upper bearing ring, said upper bearing ring displaced axially downwardly spaced away from said braking ring in a loaded condition of said bow compressing said lower ring and permitting free rotation of said upper bearing ring, and said bayonet-closure pin crossing said axial opening of said upper bearing ring.
