Abstract:
A two-wheeled wheelbarrow, cart or transporter has an assisted lift dumping barrow providing continuously biased forward tilting of the barrow relative to the frame thereof through two gas springs while maintaining the legs and wheels on the ground. A first gas spring is connected to a right side handle of the frame of the wheelchair and to a right rear underside of the barrow. A second gas spring is connected to a left side handle of the frame of the wheelbarrow and to a left rear underside of the barrow. Each gas spring provides a continuous bias or pressure against the rear of the barrow for assisting in pivoting and lifting the rear of the barrow for dumping its contents. A latch keeps the barrow from raising until released. A separate rear barrow handle aids in overcoming bias of the gas springs for lowering the rear of the barrow.

CROSS-REFERENCE TO RELATED APPLICATIONS 
       [0001]    This U.S. non-provisional patent application is a continuation-in-part of pending U.S. non-provisional patent application Ser. No. 14/546,570 filed Nov. 18, 2014 titled “Wheelbarrow With an Assisted Lift Dumping Barrow” the entire contents of which is specifically incorporated by this reference. 
     
    
     BACKGROUND OF THE INVENTION 
       [0002]    1. Field of the Invention 
         [0003]    The present invention relates to wheelbarrows and, more particularly, to wheelbarrows of various number of wheels and similar carts whose barrow can be caused to dump while the wheel(s) and frame thereof are maintained on the ground. 
         [0004]    2. Background Information 
         [0005]    Wheelbarrows to manually haul material have been in use for a long time. While wheelbarrows are generally an efficient way to move material from one point to another, a recognized problem is the ability to easily and/or precisely dump the contents of the barrow rather than merely unload its contents. This is because the barrow of a traditional wheelbarrow is fixed to the frame. Therefore, the frame must be lifted and tilted relative to its wheel in order to dump the barrow&#39;s contents. Because the load within the barrow can be 200 to 300 pounds, it may be difficult for even a strong individual to manually lift and/or tilt the wheelbarrow in order to dump its contents at a particular spot. Even when the load is light, it may not be easy for some individuals to lift and tilt the entire wheelbarrow in order to dump the contents from the barrow. 
         [0006]    In view of the above problem, various wheelbarrows have been designed throughout the years with dumping barrows. Some of these wheelbarrows are shown and described in the following U.S. Pat. Nos. 726,931; 1,063,112; 2,037,222; 2,852,304; 2,973,224; 3,092,418; 4,270,786; 6,886,838; 7,547,026; 7,775,531; 7,937,859; and 8,474,855. While these wheelbarrows all have dumping barrows, the manner in which dumping is achieved is, of course, different for each patent. Given the variety of dumping wheelbarrows, it is apparent that they must be deficient in some respects. A review of the various patented dumping mechanisms shows that it would still take an individual of particular strength to operate the dumping mechanisms and thus dump the barrow&#39;s contents. 
         [0007]    U.S. Pat. No. 4,270,786, however, recognized the aforementioned problem and thus provides a wheelbarrow in which a hydraulic piston is used to assist in forward tilting (dumping) of the pivoting barrow of the wheelbarrow. While the hydraulic piston tilts the barrow forward regardless of the weight of the barrow&#39;s contents, the wheelbarrow suffers from several deficiencies that makes its use undesirable in many situations. Particularly, the frame of the wheelbarrow must be heavy in order to support a hydraulic piston. The heavier the frame, the harder it is to lift the wheelbarrow via its handles and wheel (move) the wheelbarrow. Also, the single, center mounted hydraulic piston makes it inherently unstable during dumping of various types of barrow contents. Moreover, the user does not have complete control of the wheelbarrow or barrow during dumping since the user has to operate the hydraulic pump for the hydraulic piston. Furthermore, the use of hydraulic fluid is problematic in many respects. All of these deficiencies therefore makes its use undesirable. 
         [0008]    It is also not just one-wheeled wheelbarrows, but two-wheeled wheelbarrows, carts and the like having dumping barrows that are deficient for the above reasons, or whose dumping mechanisms, if any, are deficient. 
         [0009]    In view of the above, there is a need for an improved assisted lift dumping wheelbarrows, carts and the like of one or more wheels that overcomes the deficiencies of the prior art. 
         [0010]    It is therefore an object of the present invention to provide an improved assisted lift dumping wheelbarrow, cart or the like of one or more wheels that overcomes the deficiencies of the prior art. 
       BRIEF SUMMARY OF THE INVENTION 
       [0011]    An assisted lift dumping wheelbarrow has a forwardly pivoting barrow, and left and right biasing members that normally exert a force against the left and right rear underside of the barrow to forward tilt the barrow relative to the wheelbarrow&#39;s wheel(s) for dumping the contents of the barrow. A latch system retains the rear of the barrow onto the wheelbarrow frame against the normal bias of the left and right biasing members when not dumping. A handle is provided at the rear of the barrow to aid in overcoming the bias of the left and right biasing members when lowering the rear of the barrow for latching. 
         [0012]    The left and right biasing members are left and right gas springs, pistons, cylinders, or shocks. Because gas springs are made with different biasing strengths or forces, the amount of biasing force applied against the rear of the barrow may be easily changed as desired, needed, or required by replacing the gas spring. In this regard, the frame and underside of the barrow have left and right mounting brackets for easily attaching the left and right gas springs to the wheelbarrow. 
         [0013]    The latch system includes a spring loaded latch mounted to the underside of the barrow, preferably, but not necessarily, generally midway between the left and right sides of the barrow. The latch is operatively connected to an actuation lever that controls opening and closing of the latch, and thus the raising or lifting of the rear of the barrow and the holding or retention of the rear of the barrow. The actuation lever may be mounted the barrow handle, the frame handles, or another location as desired. A retention bar associated with the wheelbarrow frame receives the latch thereby holding the rear of the barrow onto the frame. 
         [0014]    The barrow is pivotally attached to the front of the wheelbarrow frame via one or more pivot rods that extend through left and right pivot brackets mounted to the left and right front underside of the barrow and a pivot tube connected to and between the front of the wheelbarrow frame, or separate tube brackets mounted to risers of the frame. 
         [0015]    The assisted lift dumping wheelbarrow optionally includes a foot lever attached to the rear of the barrow to aid in overcoming the bias of the left and right biasing members when lowering the rear of the barrow for latching. 
         [0016]    In one form, the assisted lift dumping wheelbarrow has a single wheel per traditional wheelbarrows. In another form, the assisted lift dumping wheelbarrow, cart, or transporter has two or more wheels. 
         [0017]    The present invention will be more apparent upon reading the following detailed description in conjunction with the accompanying drawings.

Some of these non-discussed features as well as discussed features are inherent from the figures. Other non-discussed features may be inherent in component geometry and/or configuration. 
       DETAILED DESCRIPTION OF THE INVENTION 
       [0032]    Referring to  FIGS. 1-7 , there is depicted an exemplary embodiment of a one-wheeled wheelbarrow, transporter or cart having an assisted lift dumping barrow, generally designated  10  (“assisted lift dumping wheelbarrow  10 ”), fashioned in accordance with the present principles. The assisted lift dumping wheelbarrow  10  is designed to provide easy dumping of the contents of its barrow  13  through an assisted barrow lift system  12  as described herein. The assisted barrow lift system  12  forwardly and upwardly tilts the barrow  13  relative to a frame  14  of the assisted lift dumping wheelbarrow  10 . 
         [0033]      FIGS. 1 and 2  show respectively left side and right side views of the assisted lift dumping wheelbarrow  10  (per the perspective of a user at the rear of the wheelbarrow). The assisted lift dumping wheelbarrow  10  has a frame  14  that supports the barrow  13  and includes the assisted barrow lift system  12 . The frame  14  has a left side arm  22  and a right side arm  23  that each extend from a front connector  24  to become left and right wheelbarrow handles. The left and right side arms may be any type of material such as wood, plastic or metal. Likewise, the front connector  24  may also be any type of material such as wood, plastic or metal. Preferably, however, but not necessarily, the front connector  24  is metal while the left and right side arms  22 ,  23  are wood. An axle  26  is supported on and between the left and right side arms  22 ,  23  at a front of the assisted lift dumping wheelbarrow  10  proximate the front connector  24 . The axle  26  rotatably supports a wheel (e.g. tire)  28 . 
         [0034]    A left leg  30  extends downwardly from the left side arm  22  while a right leg  32  extends downwardly from the right side arm  23 . A brace  31  is connected to and extends between the left and right legs  30 ,  32 . As is typical of wheelbarrows in general and best seen in  FIG. 7 , the left and right legs  30 ,  32  are dimensioned such that the left and right arms  22 ,  23  slant upwardly from the wheel  28  when the left and right legs  30 ,  32  are resting on the ground. 
         [0035]    The left side arm  22  holds a left barrow support  34  while the right side arm  23  holds a right barrow support  36 . The left barrow support  34  is wedge shaped having its taller end proximate the wheel  28  and thus its shorter end distal the wheel  28 . Likewise, the right barrow support  36  is wedge shaped having its taller end proximate the wheel  28  and thus its shorter end distal the wheel  28 . The wedge shape of the left and right barrow supports  34 ,  36  holds the barrow, and more particularly the bottom of the barrow, generally level with the ground (see, e.g.  FIG. 7 ) by counteracting the upward slant of the left and right side arms  22 ,  23  relative to the wheel  28 . As best seen in  FIGS. 5 and 6 , a left hinge or pivot rod bracket  70  is provided at the taller end of the left barrow support  34 , while a right hinge or pivot rod bracket  72  is provided at the taller end of the right barrow support  36 . A pivot rod tube  39  is connected at one end to the left hinge  70  and at the other end to the right hinge  72  such that the tube  39  extends between the left and right barrow supports  34 ,  36 . 
         [0036]    As best seen in  FIGS. 5 and 6 , a left side tubular bracket  40  is attached to the front left underside of the barrow  13 , while a right side tubular bracket  41  is attached to the front right underside of the barrow  13 . The left side tubular bracket  40  is positioned on the underside of the barrow  13  such that its tube is coaxial with the longitudinal axis of the pivot rod tube  39  and axially outward thereof. Likewise, the right side tubular bracket  41  is positioned on the underside of the barrow  13  such that its tube is coaxial with the longitudinal axis of the pivot rod tube  39  and axially outward thereof. A longitudinal pivot rod  42  extends through the tubes of the left and right tubular brackets  40 ,  41  of the barrow  13  and the longitudinal pivot rod tube  39  of the frame  14 . As shown in the figures, this arrangement allows the barrow  13  to pivot from an un-pivoted position (see e.g.  FIGS. 1, 2, and 7 ) relative to the frame  14  through a fully pivoted or tilted position (see  FIG. 7 ). Particularly, the front end of the barrow  13  pivots about the front portion of the frame  14  such that the rear end of the barrow  13  can tilt upwardly while the front end of the barrow  13  tilts downwardly. The forward slant of the barrow  13  dumps the contents of the barrow  13 . 
         [0037]    In accordance with the principles of the present invention, as part of the assisted barrow lift system  12 , a left side biasing member  44  is provided at a left side of the wheelbarrow, while a right side biasing member  47  is provided at a right side of the wheelbarrow. Each biasing member provides a normally outwardly bias or force particularly, but not necessarily, of the same biasing strength. The amount of outward bias or force depends on several factors such as, but not limited to, the weight of the barrow, the weight of anticipated loads, and the ability of a user to overcome the bias when lowering the rear of the barrow from a raised position to a lowered position. Biasing members having sixty pounds (60 lbs.) of compression have been successfully used. 
         [0038]    In a preferred form, the left side biasing member is a gas spring  44  (e.g. a telescoping gas spring such as known in the art) that is removably and pivotally connected at its lower end to the left side arm  22  via a lower left connection bracket  46 , and removably and pivotally connected at its upper end to the left rear underside of the barrow  13  via an upper left connection bracket  45 . The right side gas spring  47  (e.g. a telescoping gas spring such as known in the art) is removably and pivotally connected at its lower end to the right side arm  23  via a lower right connection bracket  49 , and removably and pivotally connected at its upper end to the right rear underside of the barrow  13  via an upper right connection bracket  48 . Preferably, but not necessarily, a reinforcing strip  54  is mounted to or part of the underside of the barrow  13  from the left to right side thereof. The upper left and right connections brackets  45 ,  49  would therefore be attached to the reinforcing strip  54 , otherwise directly to the underside of the barrow  13 . Other types of biasing members may be used. 
         [0039]    If the barrow  13  is not restrained, the left and right side gas springs  44 ,  47  normally upwardly bias against the rear underside of the barrow  13  to upwardly push the rear of the barrow  13  to forwardly pivot the barrow. Since there are two gas springs each located at sides of the barrow  13 , there is equal balance upon the underside of the barrow  13 . This helps prevent sideways tilting of the barrow  13  during dumping. Moreover, this equal balance aids in helping the user maintain dumping control of the wheelbarrow  10 . In order to prevent the barrow from normally being biased into a dumping position, a latch or latching system is provided that retains the rear of the barrow  13  until released. 
         [0040]    Particularly, a latch  56  is provided on the underside of the barrow  13  preferably, but not necessarily, located at a mid-point between the upper left connection bracket  45  for the left side gas spring  44  and the upper right connection bracket  48  for the right side gas spring  47 . Referring to  FIGS. 3 and 4 , the latch  56  is easily seen. The latch  56  includes a reception hook  65  and a spring-loaded arm  66  that is configured to hook onto and hold a retention bar  52  that is held by and extends between the left barrow support  34  and the right barrow support  36 . Preferably, but not necessarily, the retention bar  52  has a reduced diameter portion  53  at the middle of the retention bar  52  that is sized to be received by the latch  56 . 
         [0041]    The spring-loaded latch  56  is connected to a release mechanism that is controlled by the user. Particularly, the spring-loaded latch  56  is connected to a cable  58  within a sheath  57  that is in turn connected to an actuation lever  20 . A weight  59  may be attached to the cable  58  for aiding in latching and releasing the latch. The actuation lever  20  is coupled to a handle  16  associated with the barrow  13 . The handle  16  spans the length of the rear end of the barrow  13  and allows the user to control the barrow  13 , especially during dumping of the barrow  13  and returning the barrow  13  into the latched position. The handle  16  is attached at a left side thereof to a left vertical support  18  and at a right side thereof to a right vertical support  19 . The left and right side vertical supports  18 ,  19  extend generally from the top or rim of the barrow  13  to below the bottom or underside of the barrow  13 . In a latched position, wherein the rear of the barrow  13  is retained on the frame  14  (e.g. as in  FIGS. 1 and 2 ), the spring-loaded arm  66  of the latch  56  is normally biased to engage the rod portion  53 , thereby holding down the rear of the barrow  13  against the upward bias of the left and right side gas springs  44 ,  47 . Movement of the actuation lever  20  pulls the cable  58  within the sheath  57  to unlatch the latch  56 . 
         [0042]    The dumping wheelbarrow  10  may optionally include a mechanism that allows the user to use their foot in addition to using the handle  16  of the barrow  13  in order to lower the rear end of the barrow  13  from a dumping position to a closed, lowered, or latched position. Because the rear of the barrow  13  is biased upwardly by the left and right side gas springs  44 ,  47 , pressure needs to be exerted against this bias in order to lower the rear end of the barrow  13 . While this may be accomplished solely through the handle  16  of the barrow  13 , a pedal or stirrup  50  is provided. The pedal  50  is preferably as shown, but not necessarily, attached to a yoke  62  via a pivot rod  63  to allow the pedal  50  to swing freely about the pivot rod  63  to accommodate different foot orientations during use. The yoke  62  is in turn suspended via a connecting rod  61  to a cross member  60  which is connected to and extends between the left vertical support  18  and the right vertical support  19 . The yoke  62  is preferably as shown, but not necessarily, adjustable relative to the connecting rod  61  and thus the cross member  60  to allow for user adjustment. 
         [0043]      FIG. 7  shows the barrow  13  of the dumping wheelbarrow  10  in its latched position wherein the rear of the barrow  13  is held onto the frame  14 , and an unlatched position wherein the rear of the barrow  13  is elevated from the frame  14 . In the latched, non-dumping, lowered, loading, or transportation position, the bottom of the barrow  13  is generally parallel with respect to the left and right side arms  22 ,  23 . In the un-latched, dumping, pivoted, raised, unloading, or non-transportation position, the bottom of the barrow  13  is vertical with respect to the left and right side arms  22 ,  23 . The two-headed arrows illustrate the movement of the barrow  13  during pivoting of the barrow  13  when the barrow  13  goes from the latched position to the un-latched position and vice versa. 
         [0044]    It should be appreciated that the principles, features, components, functions and characteristics of the one-wheeled wheelbarrow  10  is applicable to two-wheeled or more wheelbarrows, carts, transporters, and/or the like having barrows. 
         [0045]    Referring to  FIGS. 8 and 9 , a two-wheeled wheelbarrow, cart, transporter, or the like (collectively, transporter)  10   a  is shown. The two-wheeled transporter  10   a,  has the same features, components, functions, and/or characteristics as the one-wheeled wheelbarrow  10 , and therefore the two-wheeled transporter  10   a  has the same reference numbers as the one-wheeled wheelbarrow  10 , the differences being those features, components, functions, and/or characteristics having reference numbers with an “a” designation. 
         [0046]    The transporter  10   a  has the assisted lift dumping barrow  13  with its left side gas spring  44 , right side gas spring  47  and attendant components that are the same as the wheelbarrow  10 , including its lift, latch and other mechanisms. The transporter  10   a  however, has first and second wheels/tires  28   a,    28   b  supported by the axle  26  outside of the right and left frame members  22 ,  23 . This adds stability to the barrow  13  and the transporter  10   a  in general. Other wheel configurations, including supports may be changed as desired. 
         [0047]    Referring to  FIG. 10 , a one-wheeled wheelbarrow, cart, transporter, or the like (collectively, transporter)  10   b  is shown. The one-wheeled transporter  10   b , generally has the same features, components, functions, and/or characteristics as the one-wheeled wheelbarrow  10 , and therefore the one-wheeled transporter  10   b,  where applicable, has the same reference numbers as the one-wheeled wheelbarrow  10 , the minor differences being those features, components, functions, and/or characteristics having reference numbers with an “a” designation, and those features, components, functions and/or characteristics that deviate more, having reference numbers not shown for the one-wheeled wheelbarrow  10 . 
         [0048]    The transporter  10   b  has the assisted lift dumping barrow  13  with its left side gas spring  44 , right side gas spring  47  and attendant components that are the same as the wheelbarrow  10 , including its lift, latch and other mechanisms. However, while not shown, the latch actuation lever/mechanism may be carried on the rear (distal the wheel  28   d ) of one of the frame arms  22 ,  23 . The transporter  10   b  however, has a single wheel  28   d  supported by the axle  26  between the right and left frame arms/members  22 ,  23 . 
         [0049]    The transporter  10   b  has a foot pedal  50   a  whose function is the same as the pedal  50  of the wheelbarrow  10 , but of a different configuration. In particular, the pedal  50   a  is a lower beam that extends between a lower end of a right vertical bar  502  and a lower end of a left vertical bar  503 . An upper end of the right vertical bar  502  is attached to a right rear underside of the barrow  13 , while an upper end of the left vertical bar  503  is attached to a left rear underside of the barrow  13 . Thus, downward pressure on the lower cross bar/foot pedal  50   a  pushes down on and lowers the barrow  13  so the barrow can latch. The right vertical bar  502  carries a stop  500  that, when the barrow  13  is in a lowered position (as shown in  FIG. 10 ), rests or stops upon the right frame arm  23 . While not seen in  FIG. 10 , the left vertical bar  503  carries a stop that, when the barrow  13  is in a lowered position (as shown in  FIG. 10 ), rests or stops upon the left frame arm  22 . 
         [0050]    The transporter  10   b  also has a right beam  510  that extends from a front right underside of the barrow  13  to a rear right underside of the barrow  13 . A generally transverse member  511  extends from the rear of the right beam  510  upwards along the rear of the barrow  13 . A left beam (not seen in  FIG. 10 ) extends from a front left underside of the barrow  13  to a rear left underside of the barrow  13 , in like manner to the right beam  510 . A generally transverse member (not seen in  FIG. 10 ) extends from the rear of the left beam upwards along the rear of the barrow  13 . A handle (like handle  16  of the wheelbarrow  10 ) but not seen in  FIG. 10 , extends between the right and left generally transverse members. The handle may carry the actuation lever  20 . While not seen, the latch  56  is provided on the underside of the barrow  13  that attaches to the cross rod  52  (see  FIG. 3 ). Cabling  57  is also provided. 
         [0051]    The transporter  10   b  further has a right support  514  that is attached to and extends from the right frame arm  23  near the front of the barrow  13 . The right support  514  carries the hinge bracket  41 . A leg  516  is attached to the front right underside of the barrow  13  that is pivotally connected to the hinge bracket  41  via hinge pin  42 . A left support  515  that is attached to and extends from the left frame arm  22  near the front of the barrow  13 . The left support  515  carries the hinge bracket  40 . A leg  517  is attached to the front left underside of the barrow  13  that is pivotally connected to the hinge bracket  41  via hinge pin  42 . The hinges of the hinge bracket  41 /right leg  516  and the hinge bracket  40 /left leg  517  allow the barrow  13  to pivot forwardly and back. 
         [0052]    Referring to  FIG. 11  a two-wheeled wheelbarrow, cart, transporter, or the like (collectively, transporter)  10   c  is shown. The two-wheeled transporter  10   c , generally has the same features, components, functions, and/or characteristics as the one-wheeled transporter  10   b,  and therefore the two-wheeled transporter  10   c,  where applicable, has the same reference numbers as the one-wheeled transporter  10   b.  The transporter  10   c  thus has the assisted lift dumping barrow  13  with its left side gas spring  44 , right side gas spring  47  and attendant components that are the same as the transporter  10   b,  including its lift, latch, beams, handle, and other components/mechanisms. The transporter  10   c  however, has first and second wheels/tires  28   e,    28   f  supported by the axle  26  outside of the right and left frame members  22 ,  23 . This adds stability to the barrow  13  and the transporter  10   c  in general. Other wheel configurations, including supports may be changed as desired. 
         [0053]    While not shown, transporters, wheelbarrow and/or carts having more than two wheels are also envisioned having a dumping barrow, tub or the like fashioned in accordance with the present principles, and are covered by the present claims. 
         [0054]    Moreover, while not shown, various members, beams or the like may be provided between the frame members in order to brace the frame, make the frame sturdier sturdy, less susceptible to movement, and/or provide lateral support for the frame and the barrow/barrow mount. For instance, one or more cross beams may be provided by and/or between the legs  30 ,  32  or the frame arms  22 ,  23  proximate the legs. Beams or members may be added elsewhere without departing from the scope of the invention. 
         [0055]    While the invention has been illustrated and described in detail in the drawings and foregoing description, the same is to be considered as illustrative and not restrictive in character, it being understood that preferred forms have been shown and described and that all changes and modifications that come within the spirit of the invention are desired to be protected.
