Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates generally to a concrete funnel and placement system, and more particularly to a funnel-type apparatus removably securable to a concrete chute comprising a retainer element coupled to a funnel element having an aperture for directing the flow of concrete to a desired location.

2. Description of the Related Art

It is common practice to make concrete in a transit-mixer truck during transit from a supply station to a worksite and to dispense the mixed slurry of concrete by means of an elongate, rigid, upwardly opening U-shaped metal concrete chute having a receiver end related to the discharge end of a mixing drum rotatably mounted relative to the transit-mixture truck and a discharge end which is adapted to be arranged upwardly from the situs of the item onto or into which the slurry is to be deposited. The receiver end of the concrete chute is typically mounted adjacent to the mixing drum so that it can be swung or pivoted in a horizontal plane as circumstances require. Further, ordinary concrete chutes are mounted so as to provide for the horizontal and/or vertical adjustments of its discharge end.

These ordinary concrete chutes are often inconvenient and difficult to use, especially if the concrete is intended for deposit in a narrow or irregularly-shaped form or in a form where the dimensions are exceptionally small. Typical of the confined spaces are footings, wall forms, masonry block cells, wall framings, casting molds or other confined spaces. While these forms are very useful, they are difficult to make. The tight space confines in these and other closely confined areas lead to great difficulties while pouring concrete.

An advantage of the funnel-type apparatus is that it can be secured to a variety of different types of chutes. In this fashion, the funnel-type apparatus can be moved from one concrete chute to another without the necessity of having a plurality of funnel-type apparatus in stock.

It is therefore desirable to provide a concrete funnel and placement system having a funnel-type apparatus removably securable to a concrete chute that efficiently and effectively directs the flow of concrete from the concrete chute in order to minimize or avoid waste and clean up.

It is further desirable to provide a funnel-type apparatus removably securable to a concrete chute which avoids wasting material and assists in the directing of the material flow.

It is still further desirable to provide a funnel-type apparatus removably securable to a concrete chute for directing the flow of concrete from a concrete chute of a concrete mixer.

It is yet further desirable to provide a funnel-type apparatus removably securable to a concrete chute that permits filling of masonry block walls.

It is yet further desirable to provide a funnel-type apparatus removably securable to a concrete chute that permits the filling of confined spaces with concrete.

It is yet further desirable to provide a funnel-type apparatus removably securable to a concrete chute that may be fitted to a variety of concrete chutes.

DETAILED DESCRIPTION OF THE INVENTION

The devices and methods discussed herein are merely illustrative of specific manners in which to make and use this invention and are not to be interpreted as limiting in scope.

While the devices and methods have been described with a certain degree of particularity, it is to be noted that many modifications may be made in the details of the construction and the arrangement of the devices and components without departing from the spirit and scope of this disclosure. It is understood that the devices and methods are not limited to the embodiments set forth herein for purposes of exemplification.

Referring to the figures of the drawings, wherein like numerals of reference designate like elements throughout the several views, and initially to FIG. 1, a concrete placement and funnel system comprising a funnel-type apparatus 10 removably secured to a concrete chute 12 on the rear end of a mixer truck 14. Existing concrete chutes 12 may be retrofitted or utilized with the funnel-type apparatus 10 or a specially designed concrete chute 12 may be utilized. The specially designed concrete chute 12 may replace the last segment in existing concrete chutes. The specially designed concrete chute 12 may include hinge holes for receipt of a hinge bar 44. The specially designed concrete chute 12 may further include alignment holes for receipt of an alignment bolt (not shown). The specially designed concrete chute's 12 hinge holes and alignment holes allow the funnel-type apparatus 10 to be leveled and oriented for a particular job. For purposes of illustration, the funnel-type apparatus 10 is shown removably secured to a rear discharge mixing truck 14; however, the funnel-type apparatus 10 disclosed herein should not be so limited. Those skilled in the art will appreciate that the funnel-type apparatus 10 may be used on front discharge mixing trucks, portable concrete mixers or any other concrete mixing/delivery devices. The funnel-type apparatus 10 includes a retainer element 16 coupled to a funnel element 18. The funnel element 18 has a base 26, which slopes downwardly and forms an aperture 20 for directing the flow of concrete 22 to a desired location, as shown in FIGS. 1 and 2 as a retaining or masonry wall 24. The base 26 should have sufficient rigidity to withstand the weight of the concrete 22. The retainer element 16 may be coupled to the funnel element 18 to form a unitary funnel-type apparatus 10.

Referring now to FIGS. 3 through 10, the funnel-type apparatus 10 is removably securable to the concrete chute 12 and includes the retainer element 16 coupled to the funnel element 18. The funnel element 18 includes a downwardly sloping base 26 forming the aperture 20 for concrete 22 to flow through. The aperture 20 may be any size or shape to fit the particulars of a specific job. The size and shape of the aperture 20 may be adjusted in order to accurately control the flow of the concrete 22. The downwardly sloping base 26 having the aperture 20 formed therein may be exchangeable or replaceable with bases having different shaped, sized and/or patterned apertures.

The retainer element 16 of the funnel-type apparatus 10 includes a sidewall 34 and a receiving section 36 for receipt of the concrete chute 12. The sidewall 34 may be generally U-shaped and may include a first terminal end 38 and a second terminal end 40. The first and second terminal ends 38 and 40 of the sidewall 34 may include a primary hinge hole 42 for receipt of a hinge bar 44 to adjustably secure the funnel-type apparatus 10 to the concrete chute 12. The primary hinge hole 42 and hinge bar 44 allow the level and orientation of the funnel-type apparatus 10 to be adjusted independently of the angle of the concrete chute 12, to which the funnel-type apparatus 10 is removably secured. The first and second terminal ends 38 and 40 of the sidewall 34 may further include a plurality of adjustment holes 46 circumferentially spaced from the primary hinge hole 42. The adjustment holes 46 may receive an adjustment bar or pin (not shown) to fix the orientation and level of the funnel-type apparatus 10 once it has been adjusted to suit the particular job.

The retainer element 16 may be hingedly secured to the concrete chute 12 allowing the retainer element 16 to be adjusted such that it is substantially horizontal while pouring concrete, independent of the angle of the concrete chute 12. The funnel-type apparatus 10 may be in communication with the mixer truck 14, thus allowing the rotation and adjustment of the funnel-type apparatus 10 to be controlled by electronics, such that the operator may be located in the cab of the mixer truck or other location.

The retainer element 16 may be rotatably coupled to the funnel element 18. When rotatably coupled to the retainer element 16, the funnel element 18 is capable of rotating 360° with respect to the retainer element 16. This rotation may be locked by the operator to prevent the funnel element 18 from inadvertently rotating during operation. The retainer element 16 may include a gasket 30 forming a seal with the funnel element 18 to prevent concrete 22 from impeding rotation.

The lower section 32 of retainer element 16 may be substantially annular and may include a collar 35. Collar 35 of the retainer element 16 may include a plurality of bearings 28 or other rotating support. The funnel element 18 may be substantially annular and include a lip 50. The lip 50 of the funnel element 18 may be rotatably coupled to the collar 35 of the retainer element 16. The funnel element 18 may also include a handle or knob 48 to aid the operator in rotating the funnel element 18.

The funnel element 18 may be rotatably coupled to the retainer element 16 using a lever lock ring 52. The lever lock ring 52 may be generally U-shaped and have a channel 54 on an interior portion. The lever lock ring 52 relies on a lever-activated mechanism 56 to bring the ends 58 and 60 of the lever lock ring 52 together. The lever lock ring 52 may include a plurality of bearings 28 allowing the funnel element 18 to rotate independently of the retainer element 16. Using of the lever lock ring 52 allows the retainer element 16 and the funnel element 18 of the funnel-type apparatus 10 to be taken apart for ease of cleaning and maintenance between uses.

The funnel-type apparatus 10 may be constructed of any light-weight, non-reactive and structurally resilient materials, including but not limited to a polymer, plastic or metal. The funnel-type apparatus 10 may also be constructed in varying sizes and shapes according to the type of mixer truck 14 or concrete chute 12 to which it is removably secured. The funnel-type apparatus 10 may also be remotely controlled allowing the operator to adjust the level and orientation, along with rotating the funnel element 18, from the cab of the mixer truck or other location.

The aperture 20 of the funnel element 18 may be of any size, shape and/or configuration to meet the needs of a particular job. An interchangeable discharge plate 62 may be removably securable to the downwardly sloping base 26 of the funnel element 18 in order to alter the size, shape and/or configuration of the aperture 20 through which the concrete flows to the desired location. For example, the interchangeable discharge plate 62 may include an opening 64 for a 6″ wall as illustrated in FIG. 14a, an opening 64 for a 4″ wall as illustrated in FIG. 14b, an opening 64 for an 8″ pier/tube as shown in FIG. 14c and openings 64 for an 8″ block filler as illustrated in FIG. 14d. It will be appreciated that a hose (not shown) may be attached to the bottom of the interchangeable discharge plate 62 illustrated in FIG. 14c using a hose clamp in order to reduce splatter, such as when pouring walls with insulation in the middle. It will be further appreciated that other interchangeable discharge plates 62 may be utilized having differing shaped, sized and configured openings 64.

Turning now to FIG. 15, the interchangeable discharge plate 62 may be removably secured to the downwardly sloping base 26 of the funnel element 18 using two (2) clips 66 secured to the bottom of the interchangeable discharge plate 62. The clips 66 are axially aligned and aligned in parallel with two (2) shoulders 68 secured to the opposing side of the bottom of the interchangeable discharge plate 62. The cooperation between the clips 66 and the shoulders 68 snuggly retain the downwardly sloping base 26 intermediate of the respective clip 66 and the bottom of the interchangeable discharge plate 62. Alternatively, the aperture 20 of the funnel element 18 may be selectively adjustable to accurately control the flow of concrete. For example, a knob may act in cooperation with the downwardly sloping base 26 to selectively open/close the aperture 20 similar to a camera shutter. In either event, when the concrete funnel and placement system is utilized with the interchangeable discharge plate 62 or selectively adjustable aperture 20, the operator must take into account slump and plate size.

Referring now to FIG. 16, which illustrates another example of the concrete funnel and placement system comprising the funnel-type apparatus 10 having the retainer element 16 rotatably coupled to the substantially annular funnel element 18. The retainer element 16 comprises the substantially annular lower section 32, a generally arcuate upstanding sidewall 34 and a receiving section 36. The receiving section 36 is removably securable to the concrete chute 12 of a mixer truck 14. The substantially annular or U-shaped upstanding sidewall 32 of the retainer element 16 includes a first terminal end 38 and a second terminal end 40. The first and second terminal ends 38 and 40 of the upstanding sidewall 34 may include a plurality of adjustment holes 46 circumferentially spaced about the pivot axis. The adjustment holes 46 may receive an adjustment bar or pin 72 to fix the orientation and level of the funnel-type apparatus 10 once it has been adjusted to suit the particular job. Further, the receiving section 36 may include a downward slope towards the funnel element 18 in order to further assist the flow of concrete from the concrete chute 12 to the desired point.

The funnel element 18 includes a downwardly sloping base 26 forming the aperture 20 for concrete 22 to flow through. As previously discussed, the aperture 20 may be any size or shape to fit the particulars of a specific job or the size and shape of the aperture 20 may be adjusted in order to accurately control the flow of the concrete 22. The downwardly sloping base 26 having the aperture 20 formed therein may be exchangeable or replaceable with bases having different shaped, sized and/or patterned apertures. The funnel element 18 may also include a handle or knob 48 to aid the operator in rotating the funnel element 18 with respect to the retainer element 16 of the funnel-type apparatus 10 of the concrete funnel and placement system disclosed herein. As illustrated in FIG. 16, the handle 48 may be elongated to enable the operator to rotate the funnel element 18 while standing upright during jobs low to the ground.

The concrete funnel and placement system may include a generally arcuate concrete chute attachment member 74 secured to the receiving section 36 of the retainer element 16 using a hinge 70. The hinge 70 is secured between the concrete chute attachment member 74 and the receiving section 36 of the retainer element along a pivot axis allowing the retainer element 16 to be adjusted such that it is substantially horizontal while pouring concrete, independent of the angle of the concrete chute 12. The concrete chute attachment member 74, being arcuate in shape, forms a channel 76 corresponding to the channel of the concrete chute 12. The concrete chute attachment member 74 includes a pair of hooks 78 to enable the concrete chute attachment member 74 to be removably secured to the concrete chute 12.

In addition, the concrete funnel and placement system may include a generally arcuate chute adapter 80 removably attachable to the concrete chute attachment member 74 for jumping from one mixer truck 14 to another. The chute adapter 80 includes a channel 82 corresponding to the channel 76 of the concrete chute attachment member 74 and a pair of opposing pegs 84 for attachment to the hooks 78 of the concrete chute attachment member 74. Also, similarly to the concrete chute attachment member 74, the chute adapter 80 includes a pair of hooks 86 to enable the chute adapter to be removably secured to the concrete chute 12 of the mixer truck 14. It will be appreciated that the chute adapter can come in varying sizes and configurations enabling the funnel-type apparatus 10 of the concrete funnel and placement system to be utilized with varying mixer trucks and concrete chutes. For example, the funnel-type apparatus 10 may be constructed to fit McNeilus mixer trucks and be provided with a chute adapter 80 to fit a KMC mixer truck.

The retainer element 16 is rotatably coupled to the funnel element 18, such as via a bearing assembly 88 enabling the funnel element 18 to rotate 360° with respect to the retainer element 16. This rotation may be locked by the operator to prevent the funnel element 18 from inadvertently rotating during operation. A gasket 30 intermediate of the funnel element 18 and the retainer element 16 forms a seal to prevent concrete 22 from impeding rotation. Referring to FIG. 17, the bearing assembly 88 may include an inner bearing block 90 secured to the lower section 32 of the retainer element 16 and an outer bearing block 92 secured to the funnel element 18. Located within a bearing channel 96 intermediate of the inner bearing block 92 and the outer bearing block 94 is at least one bearing 98 for rotatably coupling the retainer element 16 to the funnel element 18. As shown, the inner bearing block 92 includes at least one grease channel 100 for fluidly connecting the bearing channel 96 to a grease port 102, thereby providing a means for lubricating the bearings 98 within the bearing channel 96. It will be appreciated that the grease channel 100 could be located in other positions, such as within the outer bearing block 92, in keeping with the sprint and scope of the concrete funnel and placement system disclosed herein.

It will be further appreciated that the concrete funnel and placement system illustrated in FIG. 16 is designed for easy transport and will fit in the front of most mixer trucks. Further, the concrete funnel and placement system illustrated in FIG. 16 is designed to be utilized with concrete chutes that have pegs near an end section, whereas the concrete funnel and placement system illustrated in FIG. 2 is designed to be utilized when the end section of the concrete chute of the mixer truck does not have pegs or is old and distorted. Furthermore, the concrete funnel and placement system illustrated in FIG. 2 may be utilized as an extension of the concrete chute of the mixer truck, if needed.

Whereas, the devices and methods have been described in relation to the drawings and claims, it should be understood that other and further modifications, apart from those shown or suggested herein, may be made within the spirit and scope of this invention.
