Description

BACKGROUND

An anchoring adhesive is necessary to secure heavy machinery to masonry. However, the anchoring adhesive is exceedingly difficult to dispense, especially in cold temperatures. The anchoring adhesive has a high viscous level and known dispensing guns either cannot handle the required dispensing pressure and will break, or the dispensing task causes excessive fatigue in a user. Current dispensing guns also require awkward positions of the wrist and undesirable forceful and repetitive contractions of the finger and wrist flexors. The wrist and hand have been reported to have the second-highest prevalence of musculoskeletal disorders in construction workers, partially due to years of having to work with ineffective dispensing guns.

The inventors herein have recognized a need for an improved adhesive dispensing assembly that minimizes and/or reduces the above-mentioned problems.

Referring to FIGS. 1-15, a flowchart of a method for dispensing the adhesive 71 from the adhesive holding cartridge 20 in accordance with another exemplary embodiment will now be explained.

At step 320, the user provides an adhesive holding cartridge 20 having a cartridge body 70 holding an adhesive 71 therein, a dispensing tip 72 coupled to the cartridge body 70, and a slidable inner cap 76 disposed in the cartridge body 70 communicating with the adhesive 71.

At step 322, the user provides an adhesive dispensing assembly 30 having a U-shaped frame 100, a screw receiving portion 102, a cartridge holding portion 104, a screw member 106, a plunger pad 108, a handle 110, and a bolt head 112. The U-shaped frame 100 has a first end portion 141 and a second end portion 142. The screw receiving portion 102 is coupled to the first end portion 141 of the U-shaped frame 100. The screw receiving portion 102 has a threaded aperture 160 (shown in FIG. 7) extending therethrough. The cartridge holding portion 104 is coupled to the second end portion 142 of the U-shaped frame 100. The cartridge holding portion 104 has a tubular wall 180 and a ring-shaped wall 182. The tubular wall 180 has a first end 191, a second end 192, and a groove 196 extending through the tubular wall 180 from the first end 191 toward the second end 192. The ring-shaped wall 182 is coupled to the second end 192 of the tubular wall 180. The first end 191 defines a receiving aperture 198 (shown in FIG. 7). The screw member 106 has a first end portion 231, a central portion 233, and a second end portion 232. The central portion 233 is coupled to and between the first and second end portions 231, 232 of the screw member 106. The central portion 233 is threadably received through the threaded aperture 160 of the screw receiving portion 102. The plunger pad 108 is coupled to the second end portion 232 of the screw member 106. The handle 110 is coupled to the first end portion 231 of the screw member 106. The bolt head 112 is coupled to an end of the first end portion 231 of the screw member 106.

At step 324, the user couples the adhesive holding cartridge 20 to the adhesive dispensing assembly 30 such that the dispensing tip 72 extends through an aperture 210 (shown in FIG. 7) in the ring-shaped wall 182 of the cartridge holding portion 104 and a portion of the cartridge body 70 is disposed in a region 199 defined by the tubular wall 180 of the cartridge holding portion 104.

At step 326, the user rotates the screw member 106 in a first rotational direction such that the plunger pad 108 contacts the slidable inner cap 76 disposed in the cartridge body 70.

At step 328, the user removes a tip portion of the dispensing tip 72.

At step 330, the user rotates the screw member 106 in the first rotational direction such that the plunger pad 108 moves the slidable inner cap 76 further into the cartridge body 70 such that the adhesive 71 is dispensed out of the dispensing tip 72.

At step 332, the user rotates the screw member 106 in a second rotational direction such that the plunger pad 108 is moved away from the slidable inner cap 76 and outside of the cartridge body 70.

At step 334, the user de-couples the adhesive holding cartridge 20 from the adhesive dispensing assembly 30 by removing the dispensing tip 72 from the aperture 210 in the ring-shaped wall 182 of the cartridge holding portion 104 and removing the cartridge body 70 from the region 199 defined by the tubular wall 180 of the cartridge holding portion 104.
