Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     This invention relates to an improved excrement pickup device, said device having an excrement engaging portion, and a conventional bag holding portion so arranged as to hold the mouth of the bag open for ready reception of the excrement therein together with positive retention means for the bag which is quickly releasable. 
     2. Description of the Prior Art 
     A common problem with previous devices for picking up excrement and other undesirable substances is that the user of the device normally still has to touch some portion of the device which has come into contact with the excrement, and/or physically touch portions of the bag or container in which the excrement ends up. 
     Another problem with known prior art devices is that special bags and containers are necessary for proper use of said devices which increase the expense of using same as well as making said devices more inconvenient. Many times special bags and containers are not readily available &#34;at any price&#34; and therefore renders the over-all device inoperative. 
     Another problem of known prior art devices is that they are not provided with adaptable structure for picking up excrement or grass or turf-type surfaces as well as solid pavements, floors, patios, etc. 
     Prior art devices which are known to the applicant which may be pertinent to this invention are: Soergel, U.S. Pat. No. 3,711,141 and Anderson, U.S. Pat. No. 3,754,785; these patents cover devices intended primarily for holding lawn and leaf type bags open for filling during lawn cleanup operations. They are not directed toward pickup and disposal of animal excrement as is the device of this invention. A patent to Bredt, U.S. Pat. No. 3,819,220 and a patent to Johnson, U.S. Pat. No. 3,052,214 also are known; these devices are not intended for use in gathering excrement off ground or pavement, but are for the purpose of catching or receiving the excrement as it is being dropped. Also these devices require special bags or receptacles for proper use thereof. The Fisher U.S. Pat. No. 3,281,178 and the Prescott U.S. Pat. No. 3,830,423 are both directed to devices intended for pickup of excrement from the ground, but they both require special bags and/or containers for use of same. None of the known prior art devices offer the simple, inexpensive, easy-to-use and operate, excrement pickup structure as disclosed by this invention. 
     SUMMARY OF THE INVENTION 
     An object of the present invention is to provide an excrement pickup device which is easy and simple to use, and yet completely sanitary. 
     Another object of this invention is to provide an excrement pickup device usable with conventional type bags which are easily slipped onto the support portion of the device and just as easily released therefrom by simply squeezing the handle. 
     A further object of this invention is to provide a conventional bag supporting structure having a single retention hook as part of the structure so that the bag will be positively retained thereon while excrement is being picked up and the bag is being filled, and yet allowing easy, sanitary release for disposal of said bag. 
     A still further object of this invention is to provide a sanitary excrement pickup device having flexibility in that the device may be used either on ground and turf, or just as satisfactorily be used on solid pavements and floors. 
     A still further additional object of this invention is to provide an excrement pickup device which is more sanitary in operation as well as being simpler in operation than previous devices of the type. 
     These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     FIG. 1 shows the preferred embodiment of this invention indicated in general by reference numeral 10. One of the features of this device is that it is usable with conventional readily attainable shopping bags indicated by reference numeral 12. For proper use of these bags a hole 13 must be provided along one upper side thereof, but said hole is easily punched into any regular bag without requiring special bags. However the manufacturer and distributor of the excrement pickup device of this invention may, if desired, provide and sell bags with holes 13 already provided therein. 
     Looking at FIG. 2 the main features of this device may be seen. A bag supporting frame comprising two identical side portions indicated by reference numeral 14 are connected by a bend 15 at one end and attached to member 18 by welding or other fastening means 20, 32 at the other ends thereof. The upright rods 18 complete the side bag holding portion of the device and continue onto handle portion 22 as best seen in FIGS. 1 and 4. The rest of the handle includes member 24 which is a heavy wire or rod of metal similar to the rods already described. A spring-like convolution 26 is provided at one end of the rod 24 with one end of this handle being welded at 25 to the members 22 to complete the lower handle structure of the device. The other portion of the handle 27 extends to the front of the pickup device where it continues in a curved portion 28 in a U shape back under to a hook portion 30. This unique flexible handle and retention structure is part of the new and novel features of this invention. As can be seen in FIG. 2, because of the spring action of coil 26, the hook 30 will normally retain the bag 12 on the bag support sides 14 by passing through hole 13 in said bag. This will positively retain the bag on the holder and yet permit quick and easy release of said bag when the bag is to be disposed of. The dash lines of FIG. 2 indicate the release condition of said handle/holder structure. 
     Further important structure of this device consists of the excrement pickup portion best seen in FIGS. 1 and 3. A rod 16 is welded between the side rods 14 at 35 and excrement engaging members 34 are suitably welded to rod 16 at points 33. These excrement engaging members or prongs 34 readily pick up excrement from lawn or grass surfaces. 
     In operation, looking at FIG. 1, the excrement 11 shown in a clump of grass on a lawn is readily engageable by the prongs 34 therebeneath and the user of the device lifts the over-all device with the excrement resting on the top of prongs 34 and tilts the device so said excrement falls into the bag 12. Since the bag is positively retained on the holder by means of the hole 13 and hook 30 a number of pickups may be made without fear of the bag slipping off. After the bag is filled to the desired capacity it is then easily deposited in a trash pickup or other disposal container by merely holding the complete device over the container and squeezing the handle members 24, 27 together to disengage hook 30 from hole 13 and gravity force will cause the bag to drop into the disposal container. Thus the operator can pick up excrement without ever coming close to same and it is not necessary at any time to directly contact the bag. The prong members are the only portion of the over-all device that come into actual contact with the excrement and they may be readily cleaned underneath the normal outside faucet or by use of a garden hose. The rod material for the device normally would be of metal having some spring-like flexibility and preferably of the rustproof type. 
     Another embodiment of this invention is shown in FIG. 4, wherein the basic structure of the pickup device and holder is the same as that described above, and corresponding reference numerals are used. The additional feature is the member 40 which is preferably made of metal or plastic or other flexible yet rigid material. The member 40 has clips formed at two corners thereof as indicated by reference numerals 42, 44. This flat plate 40 is installed on the device on top of the tines 34 and forced rearwardly so that the offset formed in the clips hook under the horizontal bar 16 on which the tines are attached, thereby securing the plate for use as a scoop on hard surfaces. Thus as can be readily visualized the addition of this member to the previously described device makes the over-all structure readily usable for any type surface. In other words, attach the flat plate 40 for use on pavement, sidewalk, floor or other hard surface or detach the plate and use the tines for pickup of excrement from grass or turf surfaces. 
     A further embodiment of this invention is shown in FIGS. 6 and 7 wherein an envelope 50 made of thin, rigid, waxed or oiled cardboard designed to fit snugly over the tines is provided. The envelope is of the proper size to fit over the tines 34 with a slightly snug fit, thereby being retained thereon by said friction fit. With the envelope slipped over the tines as shown in FIGS. 6 and 7 the over-all device can be used as a scoop on hard surfaces and then after using, the envelope can be disposed of and a new one attached for the next use. An additional advantage of using the envelope modification is that it virtually eliminates the need for cleaning the device after use, since very little, if any, of the excrement comes in contact with the frame of the device. 
     Another variation of this embodiment is to use an envelope 50&#39; made of plastic material similar to the envelope described in the preceding paragraph. However, the plastic envelope would not necessarily be disposable, but could be used similar to the metal or plastic plate 40 described with FIGS. 4 and 5. 
     The present invention affords simple, economic means for collecting pet excreta easily and effectively without soiling the person or the individual using te device, uses readily obtainable conventional bags, said bags being readily disposable, and the need for cleaning the over-all device is practically eliminated. 
     The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
