Definitions

  • ABSTRACT OF THE DISCLOSURE A movable member for use with a camera objective whereby the operator may selectively change the member from a cap-closure, to a sunshade, to an inoperative position by means of a pivotal mounting including two pairs of elongated recesses or cut-outs disposed obliquely with respect to one another.
  • My invention has for its object an arrangement which may serve selectively as a cap .or as a sunshade for an objective.
  • said arrangement includes a member provided with a medial wall and two lateral walls, together with a mechanism for pivotally securing said member on the fitting of the objective, said member being adapted to engage the front edge of the objective through its medial wall when it is in its cap-forming position while it extends beyond the lateral and upper surfaces of the objective fitting when it is to act as a sunshade.
  • FIG. 1 is a lateral side View, partly sectional through line II of FIG. 3, .of an arrangement in its open sunshade position;
  • FIG. 2 is a similar view of the arrangement, when acting as a cap in its closed position;
  • FIG. 3 is a cross-section on a larger scale, through line III-III of FIG. 1, of the mechanism through which the arrangement is pivotally secured to the fitting of the objective;
  • FIG. 4 is a cross-section through line IV IV of FIG. 1.
  • the arrangement designated as a Whole by the reference 1 in the drawing, is incorporated with an objective system of which the fitting 2 has a square shape.
  • Said arrangement 1 includes a pivoting member 3 showing a medial transverse or top wall 4 and two depending lateral surfaces or side walls 5.
  • Said member 3 is connected with the objective fitting by a pivoting mechanism, to be described hereinafter.
  • the objective fitting 2 is provided with front edges 6 along which the medial wall 4 is engaged when the arrangement 1 is in a cap-forming position (FIG. 2) and with an upper surface 7 over which the medial surface of the member 3 lies when the arrangement is brought into its sunshade position (FIG. 1).
  • the fitting 2 is provided in each of its lateral surfaces 8 with an outer recess including two sections opening into each other and of which the section 9 has edges sloping with reference to each other while the section 10 is deeper and longer and has parallel edges.
  • the pivotal mechanism includes a slider 11 sliding in the section 10 of the recess in the fitting and provided with a notch 12 defined by two bosses 13 and 13a.
  • the notch 12 3,399,01 l Patented Aug. 27, 1968 "ice has substantially the same depth as the section 9 of the recess.
  • a screw 14 is revolvably carried in a sleeve 15 extending through or into a slot or cut-out 18 in each lateral wall 5 of the member 3 and is screwed into the corresponding slider 11.
  • the slot 18 is substantially parallel with the medial wall 4 of the pivoting member 3.
  • a spring 16 is wound, at one of its ends, round a pin 17 secured to the bottom of the shallow section 9 of the recess while the other end of said spring 16 engages the notch 12 in the slider 11 so as to abut against the rear boss 13a .on said slider.
  • the member 3 When in the position illustrated in FIG. 1, the member 3 is held against leftwards or rearwards shifting by an outwardly extending stop 19 against which the rear edge of the lateral surface 5 of said member 3 abuts.
  • said stop 19 is constituted by a socket sliding inside a blind hole 20 formed laterally in the objective fitting 2 and held inside said hole against the action of a spring 21 by a screw 22.
  • a displaceable member movable selectively to an inoperative, sunshade, or cap-closure position
  • said member including a transverse top wall and a pair of integral depending side walls, said fitting lateral surfaces provided with an elongated recess, pivot means sup-porting said member on said fitting adjacent said front edges
  • said means including a pivot carried by each said side wall and disposed within said elongated recesses, said side walls including elongated cutout portions extending in a direction parallel to said member top wall and through which said pivots pass, said recesses extending in an oblique direction with respect to said elongated cut-out portions, and means biasing said pivots toward one end of said recesses, whereby said member may be shifted about said pivot means from a capclosure position with said top wall engaging said fitting front edges to a sunshade position in which said members three walls extend forwardly
  • said slider includes a central notch and an end boss, and said biasing means engages said boss adjacent said notch.
  • said lateral surfaces include an outwardly projecting pin
  • said biasing means comprises a spring anchored to said pin and engaging said slider.
