Abstract

A glue gun including a housing, an actuator, a carrier, and a stroke adjustment mechanism. The housing extends along an axis and includes a first end and a second end opposite the first end. The first end includes an outlet configured to dispense glue from the housing. The actuator is coupled to the housing. The carrier is supported by the housing and is configured to support a glue stick. The carrier is coupled to the actuator and movable a distance along the axis in response to actuation of the actuator to guide the glue stick toward the first end. The stroke adjustment mechanism is coupled to the carrier to adjust the distance that the carrier is movable along the axis.

First claim

The invention claimed is:

1 . A glue gun comprising:
a housing extending along an axis and including a first end and a second end opposite the first end, the first end including an outlet configured to dispense glue from the housing; an actuator coupled to the housing; a carrier supported by the housing and configured to support a glue stick movable on the axis, the carrier coupled to the actuator and movable a distance along the axis in response to actuation of the actuator to guide a glue stick toward the first end; and a stroke adjustment mechanism coupled to the carrier and including a knob rotatable to adjust the distance that the carrier is movable along the axis, the stroke adjustment mechanism further including a ram coupled to the knob and on the axis, the ram extending toward and engageable with the carrier, wherein rotation of the knob moves the ram to adjust the carrier along the axis.

2 . The glue gun of claim 1 , wherein the carrier has a first position in which a maximum quantity of glue can be dispensed in response to a full actuation of the actuator, and a second position in which a minimum quantity of glue can be dispensed in response to a full actuation of the actuator.

3 . The glue gun of claim 2 , wherein the housing defines an opening between the first end and the second end of the housing, and wherein the carrier is visible via the opening in any position between the first position and the second position.

4 . The glue gun of claim 3 , wherein the housing includes indicia proximate the opening to indicate a first position and the second position.

5 . The glue gun of claim 2 , wherein the carrier is movable between the first position and the second position by rotation of the knob.

6 . The glue gun of claim 1 , wherein rotation of the knob in a first direction increases the distance the carrier is movable by the actuator, and wherein rotation of the knob in a second direction decreases the distance the carrier is movable by the actuator.

7 . The glue gun of claim 6 , wherein the knob includes indicia to indicate the first direction and the second direction.

8 . The glue gun of claim 1 , wherein the distance that the carrier is movable along the axis defines a maximum quantity of glue that can be dispensed in response to the actuator being moved a full amount.

9 . The glue gun of claim 1 , wherein the ram includes a threaded portion that engages a body to transfer rotational motion of the knob to translational motion of the ram.

10 . A glue gun comprising:
a housing extending along an axis and including a first end and a second end opposite the first end, the first end including an outlet configured to dispense glue from the housing; a projection supported by the housing adjacent the second end; a trigger assembly including
a linkage mechanism having a first linkage coupled to a second linkage, and
a trigger operably coupled to the second linkage, the trigger actuatable to translate the linkage mechanism toward the first end of the housing; and
a carrier supported by the housing and configured to support a glue stick, the carrier coupled to the trigger via the linkage mechanism and movable a distance along the axis in response to actuation of the trigger and movement of the linkage mechanism to guide the glue stick toward the first end, the projection engaged with the carrier from behind the carrier to move the carrier absent actuation of the trigger to vary the amount of glue configured to be dispensed from the housing, wherein the first linkage and the second linkage are configured to move with the carrier in response to movement of the carrier absent actuation of the trigger, and wherein the projection is disengaged from the carrier on actuation of the trigger to move the glue stick.

11 . The glue gun of claim 10 , further comprising a stroke adjustment mechanism including a knob that has the projection and that is rotatable to vary the amount of glue configured to be dispensed from the glue gun, and wherein the knob and the trigger mechanism are independently operable.

12 . The glue gun of claim 11 , wherein the knob is rotatable counter-clockwise to increase or decrease the amount of glue to be dispensed from full actuation of the trigger, and wherein the knob is rotatable clockwise to move the projection and oppositely decrease or increase the amount of glue to be dispensed from full actuation of the trigger.

13 . The glue gun of claim 11 , wherein the stroke adjustment mechanism further includes a ram coupled to the knob and defining the projection such that rotation of the knob induces translational movement of the ram, and wherein the ram is engaged with the carrier to move the carrier along the axis when the trigger is in an unactuated position.

14 . The glue gun of claim 10 , wherein the carrier includes a guide arm engaged with the housing to inhibit rotation of the carrier when the trigger is actuated.

15 . The glue gun of claim 10 , further comprising a stroke adjustment mechanism coupled to the carrier and including a knob to adjust the distance that the carrier is movable.

16 . A glue gun comprising:
a housing extending along an axis and including a first end and a second end opposite the first end, the first end including an outlet configured to dispense glue from the housing; an actuator coupled to the housing and movable between an unactuated position and a full-actuated position; a carrier supported by the housing and configured to hold a glue stick, the carrier coupled to the actuator and movable a distance along the axis in response to actuation of the actuator to guide the glue stick toward the first end; and a knob positioned on or adjacent the second end and including an aperture configured to receive and surround the glue stick on insertion of the glue stick into the housing; and a projection coupled to or engaged with the knob and defining a rearward limit of the carrier, the projection engaged with the carrier in the unactuated position.

17 . The glue gun of claim 16 , wherein the knob is rotatable to adjust an amount of glue configured to be dispensed from the glue gun in response to movement of the actuator to the full-actuated position.

18 . The glue gun of claim 17 , wherein the knob includes indicia at least partially surrounding the aperture, and wherein the indicia indicate a first rotational direction of the knob configured to increase the amount of glue to be dispensed from the glue gun and a second rotational direction of the knob configured to decrease the amount of glue to be dispensed from the glue gun.

19 . The glue gun of claim 16 , wherein the knob has a threaded body and the projection extends forward from the threaded body to engage the carrier.

20 . The glue gun of claim 16 , wherein the projection includes an aperture configured to receive and surround the glue stick on insertion of the glue stick into the housing.
