1. A greeting card display for displaying cards comprising:
a. a series of circular loops, where each loop is capable of receiving a card;
b. a wire between the circular loops where the wire coils in order to create each circular loop to create the card display; and
c. a backside, where the backside support the card display.
2. The greeting card display according to claim 1, where each circular loop is configured to receive a card.
3. The greeting card display according to claim 1, where the backside is split into two sides joined by a hinge.
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. A constant velocity universal joint comprising:
an outer joint member having track grooves formed at three positions on an inner circumference thereof, each of the track grooves having roller guiding faces provided so as to face each other in a circumferential direction and a large inner diameter portion provided between the roller guiding faces;
a tripod member having three trunnions protruding in a radial direction; and
roller assemblies attached to the respective trunnions of the tripod member, each of the roller assemblies being capable of oscillating with respect to each of the trunnions and having a roller guided in an axial direction of the outer joint member along the roller guiding faces,
wherein hardened layers are formed on the roller guiding faces of the track groove and on both end sides of the large inner diameter portion in a circumferential direction except in the vicinity of the center of the track groove.
2. The constant velocity universal joint according to claim 1, wherein
a value of FD is equal to or less than 0.45, where a distance from the center of the track groove to an end of the hardened layer on the side of the center of the track groove is F and a diameter of the outer circumference of the roller assembly is D.
3. The constant velocity universal joint according to claim 1,
wherein a value of FD is greater than 0.15 and less than or equal to 0.45 where a distance from the center of the track groove to an end of the hardened layer on the side of the center of the track groove is F and a diameter of the outer circumference of the roller assembly is D.
4. The constant velocity universal joint according to any one of claims 1 to 3, wherein
the roller assembly comprises: the roller; and a ring fitted onto the trunnion so as to rotatably support the roller.
5. The constant velocity universal joint according to claim 4, wherein
an outer circumferential face of the trunnion has a straight shape on a longitudinal section thereof, is in contact with an inner circumferential face of the ring in a direction perpendicularly crossing an axial line of the joint on the cross section, and forms a gap between the inner circumferential face of the ring in an axial direction of the joint and itself.
