FIELD OF THE INVENTION
The present invention relates to a support stand which supports a heating tool.
BACKGROUND OF THE INVENTION
The assembly and repair of electrical devices generally requires a human operator to utilize several different tools, including various hand-held heating devices such as a soldering iron for electrically securing components, a de-soldering tool for melting and removing solder to allow rework or repair, and a hot air device that may be required for heat shrink insulation. Often the operator may require all of these heating devices, along with a number of hand tools and electrical components, on the work surface of a work bench to work efficiently. However, the heating devices may easily damage electrical components, or injure the operator if they are carelessly set aside when not in use.
A diligent user may prefer placing the heating devices in some type of holder or support stand. The positioning of the heating devices in the holder or stand often depends on the user. Some users prefer putting the handle of the heating device obliquely downward toward the top surface of the work bench, and others prefer putting the handle of the heating device obliquely upward with respect to the top surface of the work bench. The orientation may depend upon how the particular user lifts and holds the heating device.
BRIEF DESCRIPTION OF THE INVENTION
The present invention provides various alternative embodiments of a support stand for heating devices that may accommodate a number of different heating devices and user preferred positioning of the heating devices when they are not in use. In addition, the present invention provides a shield to isolate the hot portion of the heating devices so that they do not damage electrical components or injure the user.
In one embodiment of the invention, the support stand includes a cradle pivotally mounted to a base, the cradle including one or more projections or stepped section on the inner surface of the cradle to engage portions of the heating device when the handle of the heating device is placed in the cradle of the support stand. The user can hook or engage the handle of the heating device on the projections or stepped section regardless of the direction of placement of the handle. Therefore the user can place the heating device on the support stand easily and stably.

DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a perspective view of a first embodiment of a support stand 10. The support stand includes a base 12 including a sloped upper surface 13, a leg member 14 and a cradle 16. The cradle 16 includes a mount 18 to secure the leg member 14 to the cradle. Alternatively, the mount 18 may be configured so that the leg member 14 may be removable to allow easy repair or replacement. The cradle 16 defines a partial generally cylindrical section 20 defining an inner surface 22, a first upwardly projecting side 24 and a second upwardly projecting side 26 so that a handle of a heating device may be rested in a space between said first side and said second side as described below. The cradle 16 further includes at least one type of projection 30 on the inner surface 22, strategically positioned to allow balance.
FIG. 2 is a perspective view of an exemplary configuration of a heating device 40. The heating device 40 may be a hot air blower, a soldering iron, a de-soldering tool or another type of tool which uses thermal energy. The heating device 40 is intended to be connected to a power supply by a cable 42, and held by a user gripping an insulated handle section 44. A heating assembly portion 46 extends from a distal end 48 of the insulated handle section 44. The insulated handle section 44 further includes a first cylindrical section 50, a beveled section 52 that flares to a greater diameter than the diameter of the cylindrical section 50, a groove 54 at the distal end of the beveled section 52, and a second cylindrical section 56 extending from the groove 54 to the distal end 48 of the handle section 44.
The configuration of the support stand 10 and the heating device 40 allows the heating device 40 to be placed in the support stand in either direction so that the heating device 40 may be oriented in either an upward angled or downward angled direction. To illustrate this concept, FIG. 3 is a simplified top-view of the cradle portion of the support stand of FIG. 1 and the central portion of the heating device 40 of FIG. 2 positioned in a first orientation obliquely upward. FIG. 4 is a simplified top-view of the cradle portion of the support stand of FIG. 1 and the central portion of the heating device of FIG. 2 positioned in a second or opposite orientation obliquely downward. In the configuration of FIG. 3, the beveled portion 52 of the handle section 44 engages the projection 30 on the inner surface 22 of the cradle 16. In the configuration of FIG. 4, the distal end of the beveled portion 52 (or the distal end of the second cylindrical section depicted in FIG. 2), engages the projection 30 on the inner surface 22 of the cradle 16. In either orientation, the engagement with the projection 30 prevents the heating device 40 from slipping downward.
In FIGS. 1, 3 and 4, the projection 30 is depicted as a ridge 30 projecting inwardly from the inner surface 22. Alternative configurations of the projection 30 on the inner surface 22 of the cradle 16 are depicted in FIGS. 5, 6 and 7. In FIG. 5, the projection 30 comprises projecting pillars 32 on the inner surface 22 of the cradle 16. The projecting pillars 32 may be configured as low-height quadratic prisms. In FIG. 6 the projection 30 comprises projecting bumps 34 on the inner surface 22 of the cradle 16. Projecting bumps 34 may be formed in hemispherical shapes. In FIG. 7, projection 30 comprises a step 36 on the inner surface 22, whereby the cradle 16 has first thickness and a second thickness. In each of these configurations, the beveled portion 52 (or the distal end of the second cylindrical section depicted in FIG. 2), engages the projecting pillars 32, projecting bumps 34, the step 36 or ridge 30.
To accommodate a user's preferences as well as various configurations for the heating devices to be rested in the support stand 10, the inner surface 22 may include a plurality of holes or openings 28 positioned in a pattern and the projecting pillars 32, the projecting bumps 34 or the ridge 30 each include a underside having projections sized to securely fit in the holes or openings of the inner surface 22, whereby the user can reposition the pillars 32, bumps 34 or ridge 30 in various locations of said inner surface 22. Thus, a user may place the respective projection at different locations along the axial length of the cradle 16 to balance different configurations of the heating device 40.
FIG. 8 is a perspective view of the first embodiment of the support stand 10 for a heating device with an additional cover unit 60 defining a heat shield assembly. The cover unit 60 includes two projection rods 62 that may be inserted into receiving sections 64 attached to the mount 18 of the cradle 16. The cover unit 60 further includes a seat shaped section including a base curving into an end section 66 and two sidewalls 68. The section 66 and sidewalls 68 may be fabricated from metal or high temperature resistant plastic materials to prevent the heating assembly portion 46 of the heating device 40 from damaging nearby electrical components or burning the user. The cover unit 60 has an open upper side that allows for heat dissipation.
FIG. 9 is a perspective view of the support stand 10 and cover unit 60 of FIG. 8 with an exemplary heating device 40. When the heating device 40 is placed in the cradle 16 of the support stand 10, the beveled section 52 of the handle section 44 engages the projection 30 in the inner surface 22 of the cradle 16, preventing axial movement. Alternatively, when the heating device 40 is placed in the cradle 16 of the support stand 10, the groove 54 at the distal end of the beveled section 52 of the handle section 44 may engage the projection 30 on the inner surface 22 of the cradle 16. The heating assembly portion 46 extends into the cover unit 60, without contacting the end section 66 or sidewalls 68. As depicted in FIG. 9, a hot air blower attachment is secured to the heating assembly portion 46. The hot air from the attachment collides with the cover unit 60 and goes up, so that objects around the hot air blower attachment are not exposed to high temperature.
FIG. 10 is a perspective view of an alternative configuration of a support stand 110 and cover unit 60 with an exemplary heating device, and FIG. 11 is a perspective view of the alternative configuration with the heating device oriented in an opposite position. In the embodiments of FIGS. 10 and 11, support stand 110 includes a base 112 having a slopped upper surface 113 and a leg 114. The support stand 110 further includes an elongated receiving slot 108 on the upper surface 113 into which a bottom end 104 of the leg 114 is inserted and secured. The configuration of the elongated receiving slot 108 allows the user to position the leg 114, and thus the cradle 116, in a comfortable position for the user while maintaining the balance for the heating device 40. The user may fix the location of the leg 114 mounting to the receiving slot 108 using screws (not shown) accessed from the underside of the base 112. In this configuration, the support stand 110 has an adjusting mechanism in order to prevent the heating device 40 from interfering with the work bench.
