Quick gliding lure
BACKGROUND OF THE INVENTION 
     The present invention relates to artificial lures. 
     Artificial lures which glide in water and widely known and used in great variety of constructions. Their purpose is to attract fish during gliding. It is advisable to propose new gliding artificial lures which have a higher attractiveness for fish and therefore can increase the fishing take. 
     SUMMARY OF THE INVENTION 
     Accordingly, it is an object of the present invention to provide a quick gliding lures which has a high attractiveness for fish. 
     In keeping with these objects and with others which will become apparent hereinafter, one feature of the present invention resides, briefly stated, in a quick gliding lure which has a cross section substantially corresponding to a cross section of a half of a falling water drop with a forward downwardly convex portion and a rearward downwardly concave portion. 
     When the artificial lure has the shape in accordance with the present invention, its resistance to water is reduced and therefore the speed of its gliding is increased. Also, the center of gravity of the lure is displaced toward the front end of the lure. The thusly designed lure has an angle of gliding of 20°-50° relative to a vertical line, so that the following tangential component of the weight of the lure is obtained: 
     
         P.sub.sin [90°-(20°÷50°)]=0.9-0.7P 
    
     This tangential component provides for a maximal speed of gliding of the lure, which attracts attention of fish of prey and increase the fishing take. 
     The novel features of the present invention are set forth in particular in the appended claims. The invention itself, however, both as to its construction and its manner of operation will be beat understood from the following description of preferred embodiments, which is accompanied by the following drawings.

     DESCRIPTION OF PREFERRED EMBODIMENTS 
     A lure in accordance with the present invention has a cross section which substantially corresponds to a cross section of a half of a falling water drop. As shown in FIG. 1 the body has an upper flat surface 1 and a lower surface which includes a front downwardly convex surface portion 2, a rear downwardly concave portion 3, and a rearmost small section 4 which is inclined from the portion 3 upwardly and rearwardly toward the upper surface 1. 
     In the lure shown in FIG. 2 the body has an upper surface 5 which is upwardly concave. The lower surface of this body corresponds to that of the body of FIG. 1. 
     In the lure shown in FIG. 3 the upper surface has an upwardly convex front portion 6 and an upwardly concave rear portion 7. As shown in FIGS. 4 and 5, the transverse cross section of the body is limited from above by a curved line 8 which can be arcuate. This cross section can be limited from below by curved lines 9 and 10 of different radii as shown in FIGS. 4 and 5. 
     For preventing lateral tilting of the lure and its spinning, the lower surface of the body can be provided with stabilizing formations. In FIG. 7 the stabilizing formation is formed as a central keel defined between two toroidal spherical surfaces as identified with reference numeral 11. In FIG. 8 a stabilizing keel 12 is formed by two conical surfaces. In FIG. 9 the stabilizing keel 13 is formed as a W-shaped projection. 
     FIGS. 10-13 shows the lures which the bodies having a pyramidal shape, an oval shape, an oval-triangular shape, and a prism-triangular shape. More particularly, the greatest cross section of the pyramid of the body of FIG. 10 is located closer to the front end, the greatest cross section of the oval-triangle of FIG. 11 is located at the front end, and a rounded surface of the prism-triangle of FIG. 13 which is the greatest is also located at the front end of the body. 
     In the lure of FIGS. 14 and 15 the rear end of the body is provided with a loop 14 for connecting a fishing line 15, while a fishing hook 16 is connected with the front end of the body. In the lure of FIGS. 16 and 17 the fishing hook 17 is connected with the front end of the body while the fishing line 19 extends through a rear rearwardly inclined loop 18 attached to the rear end of the body. In FIGS. 18 and 19 there are one front hook 20 and two lateral hooks 21 attached to the sides of the body. In FIG. 20 a hook 22 is attached to a loop 23 at the front end of the body, while in FIG. 21 a hook 24 is connected with a loop 25 at the rear end of the body and another hook 26 is fixedly connected with the front end of the body. 
     In the embodiment of FIG. 22 a fishing line 27 is attached to the body by a loop 28 which is located on a line which extends through the center of gravity of the body at an angle to an upper surface of the body, which is selected for a desired located of the longitudinal line of the lure during fishing. The same result is achieved in FIG. 23 in which instead of the loop a trough opening 29 is provided in the body at the above specified location. 
     FIG. 24 shows the body of the lure with closed holes 30, while FIG. 25 shows holes 31 in the body and communicating with an exterior of the body. The lures of FIGS. 26 and 27 are composed of at least two parts of different materials, wherein the lure of FIG. 26 has a main upper part 31 and a small lower part 32 of different materials, while the lure of FIG. 27 has a front part 33 and a rear part 34 of different materials. The materials differ from one another by their density weight. For example the materials can be metal and plastic. 
     In the embodiment of FIG. 28 the body is designed so that its center of gravity 32 is located lower than its center of resistance force of water 33. In this case the distance between the centers must be maintained at a maximum value. In the embodiment of FIG. 29 a center of gravity 34 is located higher than a center of resistance force 35, and in this case the distance between the centers must be maintained as small as possible, to provide a return of the body to the position shown in these Figures, during fishing. 
     The body of the lures must be designed so that an angle between the line which connects the center of the upper surface with the center of gravity of the body and the line connecting the rear and front upper ends of the body is between 60° (FIG. 30) and 30° (FIG. 31). As can be seen from FIG. 32, during gliding the lure glides at an angle of between 40° and 70°, since under the action of its weight the above mentioned angles of FIGS. 30 and 31 are increased by approximately 10°. 
     Fishing with the lure in accordance with the present invention is preformed in the following manner: 
     When the fishing line is connected to the rear end of the lure, the lure is sharply left up to 0.5-2 feet, then sharply lowered, then keep it still for several seconds, and repeat the cycle. 
     When the fishing line is connected near the center of gravity of the body, the lure is sharply lowered to 0.5-2 feet, and then lift it by short joits to the initial level, keep it still for several seconds, and repeat the cycle. 
     It should be additionally emphasized that the greatest width of the body of the inventive lure is provided at its uppermost surface. 
     The invention is not limited to the details shown since various modifications and structural changes are possible without departing in any way from the spirit of the present invention. 
     What is desired to be protected by Letters Patent is set forth in particular in the appended claims.
