The present invention provides a means of easily attaching and detaching a member that reinforces an envelope of a balloon to and from the envelope. Balloon 1 according to an embodiment of the present invention comprises Inner Member 121 and Outer Member 123. Each of Inner Member 121 and Outer Member 123 is a disk-shaped member made of a plastic, a light metal, or other lightweight material. Inner Member 121 and Outer Member 123 are attached to Envelope 11 by tightening Bolts 125 and Nuts 126, with Envelope 11 therebetween. A donut-shaped Rubber Seal 122 is located on the surface of Inner Member 121 in contact with Envelope 11, and a donut-shaped Rubber Seal 124 is located on the surface of Outer Member 123 in contact with Envelope 11. Rubber Seal 122 and Rubber Seal 124 are pressed tightly against Envelope 11 as Bolts 125 and Nuts 126 are tightened, and Holes H2 provided in Envelope 11 to accommodate Bolts 125 are sealed.

A storage clip includes a first finger having a top surface and a bottom surface, and a second finger having a top surface facing the first finger and a bottom surface facing away from the first finger. The second finger is connected to the first finger with an integral hinge that produces a biasing force such that a first end of the first finger is biased towards a first end of the second finger. An integral connector extends from the bottom surface of the second finger.

A tree stand platform assembly includes a platform that has a perimeter edge with a front edge, a rear edge, a first lateral edge and a second lateral edge. The platform has a top surface, a bottom surface and an outer surface positioned between the top and bottom surfaces. The front edge is configured to engage a tree. A plurality of gripping protuberances is attached to and extends outwardly from the outer surface of the rear edge. The gripping protuberances are engageable by a user for stability when the user rotates relative to the platform.

The disclosure relates to the technical field of automobile maintenance and repair as well as device calibration, and in particular, to a bracket apparatus. The bracket apparatus includes a base, a vertical rod and a clamping assembly. One end of the vertical rod is mounted to the base. The clamping assembly is mounted to the vertical rod. The clamping assembly includes a sliding member, a push rod assembly, a handle and an elastic member. One end of the sliding member is sleeved on the vertical rod. The sliding member is movable along the vertical rod. An other end of the sliding member is configured to carry a calibration element. The push rod assembly can be movably mounted to the sliding member in a preset direction. Two ends of the elastic member respectively abut against an inner wall of the sliding member and the push rod assembly. The elastic member can drive one end of the push rod assembly to be tightly pressed against the vertical rod. The sliding member is fixed to the vertical rod to prevent the sliding member from free falling and smashing. In addition, the handle is rotatably mounted to the sliding member to drive one end of the push rod assembly to be removed from contact with the vertical rod, so that the sliding member is slidable freely along the vertical rod. Therefore, the height of the calibration apparatus hung on the sliding member can be adjusted as needed, to meet different height requirements and calibration requirements.

A device holder includes a base portion, the base portion attachable to an object. The device holder further includes a ball portion mounted on the base portion. The device holder further includes a cage portion, interconnected with the base portion, the cage portion shaped to hold a mobile device.
