Definitions

  • the present invention is related to a display frame for two pictures changing at fixed positions used as a picture frame or an advertisement billboard, and especially to a display frame for two pictures in which the two different pictures can fast change automatically, and the pictures can be entirely presented for a long time.
  • the conventional structure has two defects: one is that the motor is rotated with a fixed rotational speed, when an eccentrically rotating round member with an axle as a rotating center drives the pictures to make changing, the times for entirely presenting the pictures before they get into the processes of cross changing for changing picture are short, the important effect for customers to clearly see the contents of the advertisements hence is unable to get.

  • the rotating eccentric pushing leaf 903 takes advantage of the rotating eccentric pushing leaf 903 to render the two different pictures always to keep the processes of slowly cross changing, so that the times for entirely presenting the pictures are short, the effect for presenting the entire pictures in predetermined times can not be achieved.
  • the main improvement of the present invention is that, the conventional mode to change the positions or angles of pictures or a grating plate by a moving force of a motor is changed to that one or more than one coil generates a specific magnetic force by means of a control circuit board for moving a magnet, and thereby effects that the two pictures are automatically changed and entirely presented in prolonged times can be achieved.

  • the switch is turned on to render the control circuit board to start to supply electric current for the coil 1711, and the grating plate 102 with the pictures will move to and fro between the two fixed positions, a person away from the grating plate 102 carrying pictures will naturally see changing of the different pictures alternatively.
  • Fig. 19A showing how the seventh embodiment of a picture frame of the present invention is used to change two pictures alternatively, assuming that the control circuit board has not yet supplied electric current for the coil 1611, the fixed magnet 1615 on the fixed plain plate 1614 of the "U" shaped plate adsorbs the iron sheet 1620 on the left "L" shaped movable plate 1616, at this time, if none of the pictures on the grating plate is at a correct completely presenting angular position, the position of the movable screw 1618 is micro-adjusted, the position of a plain plate 1628 having pictures thereon naturally changes, when the movable screw 1618 is micro- adjusted to make one of the pictures be completely presented, the movable screw 1618 is locked, and a fixed correct position can be obtained.
  • the "U" shaped movable plate is moved right to make the magnet 1622 on the upper plain plate 1621 at the right side of the "U” shaped plate adsorbs the iron sheet 1627 on the "L" shaped movable plate 1623; at this time, if the other picture on the grating plate is not at a correct angular position for completely presenting the picture, the movable screw 1625 is micro-adjusted, then the position of the plain plate 1628 having pictures thereon is naturally changed; when the movable screw 1625 is micro-adjusted to make the other picture be completely presented, the movable screw 1625 is locked, and the other fixed correct angular position can be obtained.
  • the two magnets 1615 and 1612 fixed on the "U" shaped plate adsorb the iron sheets 1620, 1627 on the "L” shaped movable plate 1623 to only have a function to keep the grating plate at a given angular position, their magnetic forces are designed to be constantly smaller than the rushing force generated by the magnet 1612; while the iron sheets 1620, 1627 on the "L” shaped movable plate 1623 renders the range of adsorbing area of the magnet 1612 designed to be smallest which is sufficient to make the magnet 1612 unmoved.

  • the switch is turned on to render the control circuit board to start to supply electric current for the coil 1611, and the grating plate with the pictures will move to and fro between the two fixed positions, a person away from the grating plate carrying pictures will naturally see changing of the different pictures alternatively.
  • light emitting elements can be installed under the pictures in a picture frame or an advertisement billboard, such as is depicted in Fig. 15 having a light emitting element 8121 which is suitable for a lamp case used at night or in the dark, these all fall into the scope of the present invention.
  • a plain plate 8105 has thereabove a framework 8120 that can frame four edges and a back side of a grating plate 8102 and has on two lateral sides thereof protruding cylindrical columns; the front face of the framework 8120 can be mounted with a transparent glass or plastic panel (not shown) to press flat the pictures on the grating plate 8102 to be fixed by the framework 8120, in order that the plain plate 8105 can move the grating plate 8102 carrying the pictures with a sufficient force.
  • the brand-new structures of a picture frame and an advertisement billboard for two pictures changing at fixed positions provided by the present invention can surely achieve the expected object thereof to get the effect that the two pictures are entirely presented in prolonged times.
