1. A collapsiblefoldable structure comprising:
a top roof and a bottom platform defining a top and bottom of said structure, including a vertically disposed lower side section on said bottom platform;
front and rear collapsible walls each movably positioned relative to said vertically disposed side section and which are configured to collapse inwardly into said collapsiblefoldable structure so that said front and rear collapsible walls may rest upon one another and one of said front and rear collapsible walls may rest on said bottom platform;
said front wall having an opening for egress and ingress of an animal;
a pair of sidewalls each pivotally attached to said roof to facilitate inward collapse of said sidewalls when said sidewalls are pivoted toward said bottom platform, said sidewalls further containing upper and middle sections, wherein said upper and middle sections are pivotally attached to one another so that said upper and middle sidewall sections can be pivoted inwardly towards said bottom platform;
and wherein said top roof further comprises a roof section pivotally attached to the upper sidewall sections, so that said roof section can collapse downwardly along said pivotable attachment toward said bottom platform;
said sidewalls having an outer and an inner surface thereof, and the middle wall section being pivotally attached to the vertically disposed lower side section along an inner edge of the middle wall section to permit folding of said middle sidewall inwardly toward said base, the upper wall section being pivotally attached to said middle wall section at the outer edge thereof to permit said upper wall section to collapse into contact with the outer surface of said lower wall section, and said roof section being pivotally connected to said two upper sidewall sections along the inner edges thereof to permit said top to be collapsed into contact with the inner surface of said upper wall sections.
2. The structure of claim 1 wherein said top roof, bottom platform and vertically disposed side section, pair of sidewalls and said front and rear walls are made from a thermally insulating polymeric material, polymeric foam material, expanded polystyrene foam, polyurethane foam, or structural foam material.
3. The structure of claim 1 wherein said middle and lower sections that are pivotally attached to one another are pivotally attached to one another substantially along a length of said sidewalls.
4. The structure of claim 1 wherein said sidewalls pivotally attached to said roof, are pivotally attached substantially along a length of said sidewalls.
5. The structure of claim 1 wherein said upper and middle sections pivotally attached to one another are pivotally attached substantially along a length of said sidewalls.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. An implant fixture remover comprising:
a remover screw including a first thread formed on one side thereof to be screwed to a female screw portion of an implant fixture implanted into an alveolar bone, and a second thread formed on the other side thereof; and,
a remover driver including a torque transmitting portion slide-inserted into the remover screw, and a torque providing portion formed to be separated from the torque transmitting portion and screwed to the second thread so that the torque transmitting portion maintains contact with the fixture,
wherein a force, which is applied to facing surfaces of the torque providing portion and the torque transmitting portion by a torque generated by turning the torque providing portion after the torque providing portion is screwed to the second thread, is transmitted to the fixture through the torque transmitting portion and works as a repulsive force so that the fixture is extracted from the alveolar bone,
whereby the torque transmitting portion is pressurized toward the fixture.
2. The fixture remover of claim 1, wherein a degree of slide insertion of the torque transmitting portion into the remover screw is determined based on a degree of screw coupling of the torque providing portion and the second thread.
3. The fixture remover of claim 2, further comprising a connection portion connecting the torque transmitting portion to the torque providing portion so that the torque providing portion is screwed to the second thread and so that the torque transmitting portion and the torque providing portion coact.
4. The fixture remover of claim 3, wherein the connection portion allows the facing surfaces to be in contact with each other before the torque providing portion is screwed to the second thread.
5. The fixture remover of claim 3, wherein the torque providing portion and the torque transmitting portion respectively comprises a first concavity and a second concavity recessed in a circumferential direction, and further comprises a first elastic ring and a second elastic ring respectively inserted into the first concavity and the second concavity and elastically deformed by contacting the connection portion so that the torque providing portion and the torque transmitting portion are temporarily fixed to coact by the connection portion.
6. The fixture remover of claim 1, wherein a direction of the first thread is formed to be opposite a direction of the second thread.
7. The fixture remover of claim 1, wherein the facing surfaces are defined by at least two normal vectors.
8. The fixture remover of claim 1, wherein the facing surfaces are symmetrically formed based on a virtual plane including a central axis.
9. The fixture remover of claim 8, wherein the facing surfaces comprise:
a first facing surface having a first slope based on the central axis;
a second facing surface formed continuously with the first facing surface and having a second slope greater than the first slope; and
a third facing surface formed continuously with the second facing surface and having a third slope greater than the second slope.
10. The fixture remover of claim 9, wherein the third facing surface is perpendicular to the virtual plane including the central axis.
11. The fixture remover of claim 9, wherein the first facing surface, the second facing surface, and the third facing surface are each provided in a plural number and formed spaced apart from each other.
12. The fixture remover of claim 9, wherein the number of the third facing surfaces is smaller than that of the first facing surface and the second facing surface.
13. The fixture remover of claim 1, wherein the facing surfaces of the torque providing portion and the torque transmitting portion are formed corresponding to each other.
14. The fixture remover of claim 1, wherein the torque transmitting portion includes a concave-convex contact surface in contact with the fixture so that a pressure applied toward the fixture, which is generated by the torque providing portion, is increased.
