Abstract
A mechanical holder is disclosed for holding Christmas trees of various sizes and trunk shapes. The holder includes a base, a vessel fixed to the base and provided with a centering spike, and several retaining elements regularly spaced apart around the vessel. In their retaining position above the vessel, the retaining elements can swivel independently of each other to align and retain the Christmas tree with their faces towards the axis of symmetry. According to the invention, the Christmas tree stand has a single tensioning device which applies to the tree trunk the force required to align and retain the tree. Through the action of several force transmitting elements and diverting elements, the retaining elements compensate for possible irregularities or slanted tree growth.
Claims21
A mechanical retaining device for receiving a pole member, comprising:
- retaining elements for engaging the pole member, the retaining elements being movably mounted on a base plate to move towards an axis of symmetry of the base plate;
- a force transmitting elements connected to the retaining elements so as to position said retaining elements upon tensioning of the force transmitting elements;
- a fastening element for anchoring first portions of said force transmitting element;
- a tensioning device for engaging second portions of said force transmitting elements and tensioning the force transmitting elements such that force is applied to the retaining elements to apply force to the pole member;
- a diverting element, for guiding the force transmitting elements, disposed between the retaining elements and the tensioning device;
- and
- the force transmitting elements being crossed with respect to one another between the diverting element and the retaining elements.
A mechanical retaining device for receiving a pole member, comprising:
- a base plate;
- retaining elements for engaging the pole member, the retaining elements being movably mounted on the base plate to move towards an axis of symmetry of the base plate;
- a force transmitting element connected to the retaining elements so as to position said retaining elements upon tensioning of the force transmitting element;
- a tensioning device for tensioning the force transmitting element;
- and
- a movable fastening element disposed on the base plate and having said force transmitting element anchored thereto, said movable fastening element being movable such that different ones of said retaining elements apply differing force levels to the pole member.
A mechanical retaining device for receiving a pole member, comprising:
- retaining elements for engaging the pole member, the retaining elements being movably mounted on a base plate to move towards an axis of symmetry of the base plate;
- first and second force transmitting elements respectively connected to ones of the retaining elements so as to position said retaining elements upon tensioning of the force transmitting elements;
- a first anchor for movably anchoring a first end of said first force transmitting element;
- a second anchor for movably anchoring a first end of said second force transmitting element;
- and
- a tensioning device for engaging second end of said first and second force transmitting elements and tensioning the first and second force transmitting elements such that force is applied to the retaining elements to apply force to the pole member.
