Rubber Strip Mounting Device for a Chair

Abstract

The present invention provides a rubber strip mounting device for a chair, including a rubber strip, a chair frame and at least two first mounting elements. The rubber strip has a cross section with a dovetail-shape. A groove is provided on an outer surface of the chair frame. At least two first mounting holes are formed on the chair frame such that they penetrate from the outer surface to an inner surface thereof. The rubber strip is disposed inside the groove. The at least two first mounting holes are respectively located in proximity to two ends of the groove and are in spatial communication with the groove. The at least two first mounting elements are configured to respectively mount through the at least two first mounting holes so as to fix the rubber strip.
