Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0014] FIG. 1 shows an elevational view of a dispenser assembly with portions cut-away according to embodiments of the disclosed technology.

[0015] FIG. 2 shows a cut-away side elevational view of a dispenser assembly with two opposing handles according to embodiments of the disclosed technology.

[0016] FIG. 3 is a stand-alone view of a holding assembly and trigger mechanism that may be used to carry out embodiments of the disclosed technology.

[0017] FIG. 4 shows an exemplary compound cartridge that may be used in one or more embodiments of the dispenser of the disclosed technology.

[0018] A better understanding of the disclosed technology will be obtained from the following detailed description of embodiments of the disclosed technology, taken in conjunction with the drawings.

DETAILED DESCRIPTION

[0019] References will now be made in detail to the present exemplary embodiments, examples of which are illustrated in the accompanying drawings. Certain examples are shown in the above-identified figures and described in detail below. In describing these examples, like or identical reference numbers are used to identify common or similar elements. The figures are not necessarily to scale and certain features and certain views of the figures may be shown exaggerated in scale or in schematic for clarity and/or conciseness.

[0020] Referring now to FIG. 1, an elevational view is shown of a dispenser assembly with portions cut-away according to embodiments of the disclosed technology. The dispenser includes a plunger or contacting element 151 having a plunger shaft or longitudinal actuator 130 with teeth 131 which is driven by a first holding assembly 100. The first holding assembly 100 has a fixed handle 110. The dispenser includes a housing 138, and a trigger member 120 pivoted at a screw hinge located piston above the longitudinal actuator 130. At an end of the housing 138, a cuff or lip 136 is employed to retain compound containing cylinders within the housing. The compound containing cylinders are contained within a void or an open area 137 defined by the housing 138.

[0021] In further embodiments, the first assembly 100 may further include a bearing assembly located on or near a portion of trigger 120 which extends above screw hinge. In addition, a trigger stop mechanism may be provided on the downwardly extending handle 110 to adjust the arc of trigger 120 for reducing hand fatigue.

[0022] Referring still to FIG. 1, a second holding assembly 200 may be provided opposite to the first holding assembly 100 with respect to the actuator 130. The second holding assembly 200 may likewise have a second handle 210 and a second trigger 220. Each of the holding assemblies 100, 200 may be used to hingedly thrust the actuator 130 forward. The teeth 131 are contacted by portions of the triggers 120, 220 to cause the actuator 130 to thrust away from the assemblies to cause compound to be extruded from a cylindrical cartridge. The actuator 130 extends through an opening 135 disposed at an end of the housing 138.

[0023] FIG. 2 shows a cut-away side elevational view of a dispenser assembly with two opposing handles according to embodiments of the disclosed technology. In this embodiment, the second handle assembly 200 is disposed on the opposite end of the housing 138 from the first handle assembly 100. Likewise, the second trigger 220 in oriented in the opposite direction from the first trigger 120. This embodiment enables a user to use two hands to carefully eject and apply compound.

[0024] FIG. 3 is a stand-alone view of a holding assembly and trigger mechanism that may be used to carry out embodiments of the disclosed technology. More particularly, FIG. 3 shows the second holding assembly 200 of FIG. 2 in greater detail. As depicted, the second holding assembly has a second handle 210 and a second trigger 220 which, when pressed towards one another, cause the actuator to be incrementally biased through the housing.

[0025] The stand-alone view of FIG. 3 is also indicative of the ability of the second holding assembly 200 to be detached from dispenser and releasably attached to another portion of the dispenser. Thus, for example, the second assembly 200 of FIG. 1 may be detached, and reattached in a configuration similar to that of FIG. 2. The different arrangements may be suitable for different uses and applications of the dispenser.

[0026] FIG. 4 shows an exemplary compound cartridge that may be used in one or more embodiments of the dispenser of the disclosed technology. The term caulk and/or compound are used throughout the application, but it will be readily understood that the invention is not limited to any one particular material, and that the material being dispensed may be selected from a wide variety of materials such as sealants and adhesives, viscous grinding compounds and lubricating materials, paints, colors and colorants, and even food materials. Such compounds are typically stored in a cartridge 10 having an elongated, cylindrical tube 12. The cartridges 10 are disposable and have a nozzle 20 at one end 16, and an opening at the other end 22. In the opening a plate or actuator 14 sits firmly within the tube 12. In order to extrude compound material, the actuator 14 (not to be confused with the longitudinal actuator of the dispenser) is pushed towards the nozzle 20 to forcibly eject the viscous compound through an opening 24 in the nozzle.

[0027] While the disclosed invention has been taught with specific reference to the above embodiments, a person having ordinary skill in the art will recognize that changes can be made in form and detail without departing from the spirit and the scope of the invention. The described embodiments are to be considered in all respects only as illustrative and not restrictive. All changes that come within the meaning and range of equivalency of the claims are to be embraced within their scope. Combinations of any of the devices described hereinabove are also contemplated and within the scope of the invention.
