Abstract: A motorized viscous material dispenser, especially a caulking gun, comprises a motor (27), an operation parameter sensor (51), a data processing device (35), a memory device (37), and at least one operator activated switch (7, 10). The dispenser has a first dispensing mode in which the data processing device (53) records operation parameter values read by the operation parameter sensor (51), when a switch (7) is activated by an operator, and stores at least one operation parameter value in the memory device (37), the motor (27) being activated in accordance with the activation of said switch (7), and a second dispensing mode in which the data processing device (35) activates the motor (27) in accordance with the operation parameter values stored in the memory device (37) when a switch (7) is activated by an operator.

Abstract: A motorized viscous material dispenser (1), especially a caulking gun, comprises a drive unit (11) with a cylindrical pinion gear, a holder (15) attachable to a front side of the drive unit (11) for receiving at least one container containing viscous material, at least one piston (19), and at least one rack (17) meshing with the cylindrical pinion gear to drive said piston (19). A rear piece (51) attachable to a rear side of the drive unit (11) opposite the front side and a guide piece (45) attachable to the front side of the drive unit (11) comprises guiding apertures (55) through which the rack (17) is extending, whereby the guiding apertures (55) determine the position of the rack (17) relative to the cylindrical pinion gear, when the motorized viscous material dispenser (1) is assembled.

Abstract: An articulated driving mechanism for a dispenser which in one embodiment is a caulking gun has a series of rigid links that are secured to one another by pins. The pins can slide in a slot which allows the links to space away from one another in a first position or be squeezed side by side which then prevents any rotation in a second position. The links all have ratchet teeth to engage two different driving wheels. The two driving wheels rotate at different speeds which allows the links to be consistently opened before reaching a circumferential wheel so that then the spaced links can rotate and safely and reliably rotate as they follow the circumference of the wheel. The articulated driving mechanism is used as a substitute for a push rod in a caulking gun in at least one embodiment.

Abstract: An articulated driving mechanism (2) is composed of several inflexible links (1, 1?, 1?, 79, 84) in succession, the links of each pair of adjacent links being interconnected by means of a link pin (16, 16?, 16?), arranged in both the adjacent links in such a manner that the links are pivotal in relation to one another about the axis of the pin. The links of each pair of adjacent links are mutually displaceable in the transverse direction of the link pin between a first position, in which the adjacent links are pivotal in relation to one another about the axis of the link pin, and a second position, in which corresponding meshing surfaces of each adjacent link abut one another and lock against mutual pivoting of the adjacent links. The link pin is displaceable in an elongated hole (23, 82, 89) in at least one of the links.
