Abstract

A portable grout device is provided. The device includes a grout hopper, a cylindrical tube portion connected to and operable to receive grout from the grout hopper, and a drive shaft and auger assembly within the cylindrical tube portion. The drive shaft and auger assembly includes a central shaft and a helical auger screw operable to push the grout out of an end of the cylindrical tube portion.

Claims (49)

1. A portable grout device comprising:

a grout hopper;

a cylindrical tube portion connected to and operable to receive grout from the grout hopper, wherein the cylindrical tube portion includes:

a constant inner diameter along a length of the cylindrical tube portion; and

a dispensing end with an inner diameter equal to the constant inner diameter and configured for dispensing the grout from the portable grout device; and

a drive shaft and auger assembly within the cylindrical tube portion including:

a central shaft including a first end portion, a second end portion distal from the first end portion, and a central point on the central shaft between the first end portion and the second end portion;

a disk-shaped thrust washer formed upon the first end portion; and

a helical auger screw operable to push the grout out of the dispensing end of the cylindrical tube portion, wherein the helical auger screw extends from the central point to the second end portion and wherein the central shaft includes a helical auger screw-free portion between the central point and the disk-shaped thrust washer; and

wherein the portable grout device is configured for the grout to flow from the dispensing end to be utilized upon a working surface at a diameter equal to the constant inner diameter; and

wherein the portable grout device is configured to be handheld.

2. The portable grout device of claim 1 , wherein the dispensing end of the cylindrical tube portion includes a second end of the cylindrical tube portion; and

wherein the drive shaft and auger assembly further includes a drive shaft shank formed upon the first end portion and extending from a first end of the cylindrical tube portion, wherein the drive shaft shank is operable to be driven by a handheld torque generating device.

3. The portable grout device of claim 2 , further comprising a removeable end cap fastened upon the first end of the cylindrical tube portion, wherein the removeable end cap includes a central aperture through which the drive shaft shank extends therethrough; and

wherein the disk-shaped thrust washer is disposed within the cylindrical tube portion and is held within the cylindrical tube portion during operation of the portable grout device by the removeable end cap.

4. The portable grout device of claim 1 , wherein the grout hopper includes a handle.

5. A portable grout system, comprising:

a portable grout device including:

a grout hopper;

a cylindrical tube portion connected to and operable to receive grout from the grout hopper, wherein the cylindrical tube portion includes:

a constant inner diameter along a length of the cylindrical tube portion; and

a dispensing end with an inner diameter equal to the constant inner diameter and configured for dispensing the grout from the portable grout device;

a drive shaft and auger assembly within the cylindrical tube portion including:

a central shaft including a first end portion, a second end portion distal from the first end portion, and a central point on the central shaft between the first end portion and the second end portion;

a disk-shaped thrust washer formed upon the first end portion; and

a helical auger screw operable to push the grout out of the dispensing end of the cylindrical tube portion, wherein the helical auger screw extends from the central point to the second end portion and wherein the central shaft includes a helical auger screw-free portion between the central point and the disk-shaped thrust washer; and

a portable torque generating device connected to the drive shaft and auger assembly; and

wherein the portable grout device is configured for the grout to flow from the dispensing end to be utilized upon a working surface at a diameter equal to the constant inner diameter; and

wherein the portable grout device is configured to be handheld.

6. The portable grout system of claim 5 , wherein the portable torque generating device includes a cordless drill device.

7. The portable grout system of claim 5 , wherein the dispensing end of the cylindrical tube portion includes a second end of the cylindrical tube portion; and

wherein the drive shaft and auger assembly includes a drive shaft shank formed upon the first end portion and extending from a first end of the cylindrical tube portion, wherein the drive shaft shank is operable to be driven by the portable torque generating device.

8. The portable grout system of claim 7 , further comprising a removeable end cap fastened upon the first end of the cylindrical tube portion, wherein the removeable end cap includes a central aperture through which the drive shaft shank extends therethrough; and

wherein the disk-shaped thrust washer is disposed within the cylindrical tube portion and is held within the cylindrical tube portion during operation of the portable grout device by the removeable end cap.

9. The portable grout system of claim 5 , wherein the grout hopper includes a handle.

10. A portable grout device comprising:

a grout hopper including a handle portion;

a cylindrical tube portion connected to and operable to receive grout from the grout hopper, wherein the cylindrical tube portion includes:

a constant inner diameter along a length of the cylindrical tube portion;

a second end, wherein the second end is a dispensing end with an inner diameter equal to the constant inner diameter and configured for dispensing the grout from the portable grout device; and

a first end;

a drive shaft and auger assembly within the cylindrical tube portion including:

a central shaft including a first end portion, a second end portion distal from the first end portion, and a central point on the central shaft between the first end portion and the second end portion;

a disk-shaped thrust washer formed upon the first end portion;

a helical auger screw operable to push the grout out of the second end of the cylindrical tube portion, wherein the helical auger screw extends from the central point to the second end portion and wherein the central shaft includes a helical auger screw-free portion between the central point and the disk-shaped thrust washer; and

a drive shaft shank formed upon the first end portion and extending from the first end of the cylindrical tube portion, wherein the drive shaft shank is operable to be driven by a handheld torque generating device; and

a removeable end cap fastened upon the first end of the cylindrical tube portion, wherein the removeable end cap includes a central aperture through which the drive shaft shank extends therethrough; and

wherein the disk-shaped thrust washer is disposed within the cylindrical tube portion and is held within the cylindrical tube portion during operation of the portable grout device by the removeable end cap;

wherein the portable grout device is configured for the grout to flow from the dispensing end to be utilized upon a working surface at a diameter equal to the constant inner diameter; and p 1 wherein the portable grout device is configured to be handheld.
