Supporting post for motor shade
View Patent ↗A supporting post for motor shade includes a length-adjustable extendable post, a protective sleeve movably mounted on the extendable post, a movable fixing assembly mounted on the extendable post to provide an elastic tension, and a bottom seat with a universal joint connected to a lower end of the extendable post. The supporting post is upright erected beside a car with the movable fixing assembly elastically upward abutting on a lower edge of the car. The protective sleeve prevents the rigid extendable post from abrading the car, and the bottom seat with the universal joint allows the extendable post to stably stand on a rough or slope ground surface. A shade supported on four pieces of the extendable posts is distantly located above a car to effectively shield the car from sunlight, heat, and rainwater when the car is parked in an open-air place.
1. A supporting post for motor shade, comprising:
an extendable post having a freely adjustable overall length, and being provided at a top with a supporting bracket;
a movable fixing assembly including a supporting element, an elastic element, and a locating device; said supporting element including a hollow sleeve for movably mounting around said extendable post, and a supporting arm sideward extended from one side of said hollow sleeve; said elastic element being mounted on said extendable post below said supporting element; and said locating device being axially movable along and discretionally fixed on said extendable post below said elastic element; and
a ground seat being connected to a lower end of said extendable post;
whereby when said supporting element of said movable fixing assembly is adjusted to a desired height on said extendable post and said locating device is fixed to a suitable position on said extendable post to compress said elastic element between said supporting element and said locating device, an elastic tension is produced by said compressed elastic element to firmly push said supporting arm upward.
2. The supporting post for motor shade as claimed in claim 1 , further comprising a soft hollow protective sleeve being axially adjustably mounted on said extendable post immediately above said supporting element.
3. The supporting post for motor shade as claimed in claim 1 , wherein said extendable post includes at least two hollow pipes connected to each other end to end, and wherein said supporting bracket defines a U-shaped space.
4. The supporting post for motor shade as claimed in claim 1 , wherein said locating device includes an upper ring, a lower ring, and a tension ring positioned between said upper and said lower ring, whereby when said upper ring is screwed into said lower ring to compress said tension ring, said tension ring is forced against and thereby tightly attached to an outer surface of said extendable post to lock said locating device to said extendable post.
5. The supporting post for motor shade as claimed in claim 1 , wherein said bottom seat includes a ground plate and a universal joint; said ground plate being formed at an end with an upward extended socket; and said universal joint including a lower spherical portion downward fitted in said socket on said ground plate, and an upper column portion upward extended into the lower end of said extendable post, such that said ground plate is freely turnable to different angular positions relative to said extendable post.
