Abstract
Official abstract text for this publication.
A spring fixing structure includes a louver provided with a stopping member and a louver fixation portion thereon, and a spring disposed on the louver, the spring including a spring fixation portion fixed on the louver fixation portion and two arcuate spring legs. The stopping member is provided with a retaining mechanism for retaining the spring. The spring of the present invention can be easily mounted on the louver and prevented from being deformed.
First claim
Opening claim text (preview).
What is claimed is: 1. A spring fixing structure, comprising a louver provided with a stopping member and a louver fixation portion, and a spring disposed on the louver, the spring comprising a spring fixation portion fixed on the louver fixation portion and two arcuate spring legs, wherein the stopping member is provided with a retaining mechanism for retaining the spring legs of the spring, wherein an imaginary line is defined by linearly extending a bottom of the spring fixation portion in a direction in which the spring legs extend in a horizontal direction of the louver, and the spring legs each have a highest point defined as having a longest perpendicular distance from the imaginary line when the spring is horizontally laid to be parallel with the louver and is not restrained by the stopping member; and wherein a perpendicular distance from the stopping member to the imaginary line is smaller than a perpendicular distance from the highest points of the spring legs to the imaginary line when the spring is horizontally laid on the louver, wherein the retaining mechanism is provided on the stopping member, and the retaining mechanism is one of a notch, a recess, and a retaining tab, and the retaining mechanism holds the spring in a deformed state. 2. The spring fixing structure according to claim 1 , wherein the stopping member is in a form of a cross bar. 3. The spring fixing structure according to claim 1 , wherein the corners of the retaining tab are chamfered or rounded. 4. The spring fixing structure according to claim 1 , wherein the retaining tab is located at a position corresponding to the highest point of the arcuate spring leg. 5. The spring fixing structure according to claim 4 , wherein the corners of the retaining tab are chamfered or rounded. 6. The spring fixing structure according to claim 1 , the recess or notch being located at a position corresponding to the highest point of the arcuate spring leg. 7. The spring fixing structure according to claim 1 , wherein a hanging part is provided on a side of the retaining tab facing the imaginary line to protrude downwards.
