This invention relates to improvements. in' and connected with supporting brackets for blinds and the like and has been devised particularly for outwardly and downwardly inclined sun blinds such as those usedin small sizes for'the windows; of sedan automobiles and in larger sizes above windows, porches andv the like, of buildings} The invention broadly consists in attaching a 'portion'of a 'blind or thelilge to a pivotedmemf her and in'providing the-pivotal support'for the member with non-circular interlocking members which may be engaged at one for more predetermined'positions to prevent relatitve movement therebetween, and retain-the said pivoted member in adjusted positions corresponding thereto.

, In one form of the invention, the pivoted memr V ber for the blind is provided with a pivot pin hav ng, a relatively narrow tongue which is mounted in'a bearing having one or more substantially radial slots adaptedto aecommodate the said tongue of the pivot pin atithe said predetermined locking positions whereby the blind will be firmly supported in snch operative positions. 7

'The engagement between the interlocking the tension exerted on the blind by the "roller tends to aut matically lock the arms inwtheir Itwill be understood'tha t the interlocking me e ima esc a ran t t he suppers ing arms maybe securely retained in one or more alternative positions.
