Description

BACKGROUND OF THE PRESENT INVENTION

1. Field of Invention

The present invention relates to flag pole devices and more particularly, to such a flag pole device, which assures synchronous rotation of the flag-mounting upper and lower rotary barrels relative to the pole, avoiding tangling of the flag on the pole.

2. Description of Related Arts

A conventional flag pole generally comprises two bearing portions for the fastening of the inner upper and lower corners of a flag. During application, the flag may be tangled on the pole due to the effect of wind force. To avoid the flag from tangling on the pole, a flag pole device is disclosed using a connection rod to connect two or three rotary members that are pivotally mounted on the pole for securing the flag. When the flag is flying upon the wind, the rotary members can be synchronously rotated relative to the pole, avoiding the flag from tangling on the pole. This improved design is seen in Taiwan Patent M263591. However, as the connection rod is a round rod coupled between the rotary members. During application, the connection between the connection rod and each rotary member may be loosened. When this condition occurred, the rotary members may be not rotated synchronously relative to the pole. If the rotary members cannot be rotated synchronously relative to the pole, the flag may be tangled on the pole when flying in the wind.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIGS. 1 and 2, a flag pole device in accordance with the present invention is shown comprising a pole 1, an upper rotary barrel 2, a lower rotary barrel 3, a connection rod 4 and an anchoring member 5.

The pole 1 has a convex top edge 11 (see FIG. 3), and a screw hole 12 located on the center of the convex top edge 11 for the mounting of an ornament 6 (see FIG. 4).

The upper rotary barrel 2 comprises a top wall 24 supported on the convex top edge 11 of the pole 1 and rotatable with the upper rotary barrel 2 relative to the pole 1 (see FIG. 4), a through hole 25 cut through the top wall 24 and in axial alignment with the screw hole 12 for the passing of the bottom screw rod 61 of the ornament 6 for enabling the bottom screw rod 61 to be threaded into the screw hole 12, a lug 21 protruded from the peripheral surface thereof at one side near the top wall 24 for the hanging of the inner upper corner of a flag 7 (see FIG. 3), and a side column 22 formed integral with the peripheral surface and longitudinally disposed opposite to the lug 21. After the bottom screw rod 61 of the ornament 6 is inserted through the through hole 25 and threaded into the screw hole 12, a gap G is left between the ornament 6 and the top wall 24, allowing free rotation of the upper rotary barrel 2 relative to the pole 1. The side column 22 comprises a through hole 23 cutting through opposing top and bottom sides thereof. The through hole 23 comprises a flat bottom hole portion 231, a crossed hole portion 232 disposed at the top side of the flat bottom hole portion 231, and a step 233 defined between the flat bottom hole portion 231 and the crossed hole portion 232.

The lower rotary barrel 3 is sleeved onto the pole 1, comprising a lug 31 protruded from the peripheral surface thereof at one side for the hanging of the inner lower corner of the flag 7 (see FIG. 3), and a side column 32 formed integral with the peripheral surface and longitudinally disposed opposite to the lug 31. The side column 32 comprises a through hole 33 cutting through opposing top and bottom sides thereof. The through hole 33 comprises a flat top hole portion 331, a crossed hole portion 332 disposed at the bottom side of the flat top hole portion 331, and a step 333 defined between the flat top hole portion 331 and the crossed hole portion 332.

The connection rod 4 is coupled between the upper rotary barrel 2 and the lower rotary barrel 3, comprising opposing flat top end portion 41 and flat bottom end portion 42 disposed in the same plane (see FIG. 3). The flat top end portion 41 is inserted upwardly through the flat bottom hole portion 231 of the through hole 23 of the upper rotary barrel 2 (see FIGS. 5 and 6) and then rotated through a predetermined angle and then lowered and positioned in the crossed hole portion 232 and stopped at the step 233 of the through hole 23 of the upper rotary barrel 2 (see FIGS. 7 and 8). The flat bottom end portion 42 is inserted downwardly through the flat top hole portion 331 of the through hole 33 of the lower rotary barrel 3 (see FIGS. 9 and 10) and then rotated through a predetermined angle and then lifted and positioned in the crossed hole portion 332 and stopped at the step 333 of the through hole 33 of the lower rotary barrel 3 (see FIGS. 11 and 12). Further, an upper stop member 26 is plugged into the top end of the through hole 23 of the side column 22 of the upper rotary barrel 2 to stop the connection rod 4 in the side column 22 of the upper rotary barrel 2 (see FIGS. 4 and 7); a lower stop member 34 is plugged into the bottom end of the through hole 33 of the side column 32 of the lower rotary barrel 3 to stop the connection rod 4 in the side column 32 of the lower rotary barrel 3 (see FIGS. 4 and 11).

The anchoring member 5 comprises a round tube 51, and an angle bar 52 fixedly fastened to the bottom end of the round tube 51 (see FIG. 1). The angle bar 52 has a pointed bottom end piece 53 for fastening to the ground. The round tube 51 has a pin hole 511 transversely cut through the tube wall thereof at a selected location (see FIG. 2). Further, the pole 1 comprises a spring-supported retainer rod 13 disposed near the bottom end thereof, which, when the bottom end of the pole 1 is inserted into the round tube 51 is engaged into the pin hole 511 of the round tube 51 (see FIG. 13). Pressing the spring-supported retainer rod 13 allows separation of the pole 1 from the round tube 51. Further, the angle bar 52 has a hitting lug 54 at one lateral side thereof for the grasping of the hitting to apply force to the anchoring member 5.

During application, the flat top end portion 41 and flat bottom end portion 42 of the connection rod 4 are respectively positioned in the through hole 23 of the side column 22 of the upper rotary barrel 2 and the through hole 33 of the side column 32 of the lower rotary barrel 3 and respectively stopped at the respective steps 233;333 and kept in the same plane. Thus, the upper rotary barrel 2 and the lower rotary barrel 3 are synchronously rotatable relative to the pole 1. When the upper and lower parts of the flag 7 are forced by different wind forces to oscillate in different directions, the upper rotary barrel 2 and the lower rotary barrel 3 are synchronously rotated relative to the pole 1, avoiding tangling of the flag 7 on the pole 1. Further, the upper stop member 26 and the lower stop member 34 are respectively fastened to the top end of the through hole 23 of the side column 22 of the upper rotary barrel 2 and the bottom end of the through hole 33 of the side column 32 of the lower rotary barrel 3, avoiding separation of the connection rod 4 from the upper rotary barrel 2 or the lower rotary barrel 3, assuring a high level of structural stability.

Further, the anchoring member 5 is conveniently detachably fastened to the pole 1. By means of the pointed bottom end piece 53 of the angle bar 52, the anchoring member 5 can easily be driven into the soil.

Although a particular embodiment of the invention has been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the invention. Accordingly, the invention is not to be limited except as by the appended claims.
