GRADUATED, RETRACTABLE, LATERALLY ROTATING SPREADING DEVICE FOR CLASSROOM DESKS

Abstract

This invention relates to a mechanical spacer used for positioning classroom desks at a selected spacing relative to adjacent desks. The device comprises a mounting body attached to the support profile of the classroom desk, an inner spacer arm that moves linearly within a closed-section guide channel of the mounting body, a spring-loaded locking pin that secures the inner spacer arm in various outward positions, a mechanical status indicator showing the locking status, an outer spacer arm connected to the outer end of the inner spacer arm by a vertical hinge pin, a centering ball and centering housing that holds the outer spacer arm in line with the inner spacer arm, a contact lug located at the free end of the outer spacer arm, and a retraction centering device. When the locking pin enters the selected locking housing, it secures the inner spacer arm in its working position and makes the colored indicator surface visible in the indicator window. The contact lug makes contact with the adjacent desk without forming a locking connection.When the torque generated by the lateral force applied to the outer spacer arm exceeds the holding moment of the centering mechanism, the centering ball dismounts from its centering housing, and the outer spacer arm rotates around the vertical hinge pin. During the retraction of the inner spacer arm towards the mounting body, the opposing centering surfaces bring the outer spacer arm to the center position. At the end of use, both the inner and outer spacer arms are retracted into the guide channel of the mounting body.
