The present invention relates to handheld devices for pressing or creasing fabric.
The iron is one of the most widely owned and used household appliances. Since its introduction, the typical household iron has solved the problem of wrinkled attire for many a person. With advances such as steam production and thermostats, the iron has become more versatile as well as easier to use. However, there still exists those users and those particular jobs for which even the most technologically advanced irons are not proper.
One major drawback to the conventional household iron is that it requires a hard flat surface to support the garment or other fabric article to be pressed. Normally, an ironing board is the clear choice for such a surface. However, ironing boards take up significant space and may not be appropriate for all types of jobs. Often, when ironing boards are not available, flat surfaces such as those on tables or counter tops are utilized. However, pressing an article on a surface not particularly suited for use with a heated iron brings with it the possibility that the surface or the fabric article can be damaged.
Another drawback to the conventional household iron lies within the realm of hanging fabric articles. All too frequently, drapes in a house become wrinkled and detract from the aesthetic beauty of the decorum. With the pressing of articles such as these, the battle lies both in removing them from their vertical mounting and in manipulating their sheer size. Similarly, providing creases in the desired locations can be an overwhelming task.
Attempts have been made to improve upon the conventional household iron. For example, the prior art shows a hand tool for pressing garments. This device is essentially a handheld iron with a pivotably attached surface portion which can be pivoted into contact with a heated sole plate through actuation of a handle. In use, a piece of fabric is placed between the surface portion and the sole plate. The surface portion is then pivoted to capture the fabric between the surface portion and the sole plate. While the device taught in the prior art is useful, it has several drawbacks. For example, the pivotable nature of the connection between the surface portion and the sole plate greatly limits the displacement between the two elements at the rear or connection point and axiomatically limits the amount of fabric that can be inserted between them. The pivotable connection also prevents uniform pressing from occurring over a distance of fabric. Furthermore, prior art devices of this type do not teach combining a steam generating apparatus with the iron.
Therefore, there exists a need for a small, handheld iron which allows for the uniform pressing of fabric articles without an ironing board. A device of this type is useful in many circumstances including traveling or the pressing of hanging fabric articles.
A first aspect of the present invention is a handheld ironing device comprising a body portion having a substantially flat body surface and a platform having a substantially flat platform surface. The platform surface is moveably associated with the body portion such that the platform surface opposes the body surface and such that the body surface and the platform surface remain in substantially parallel planes throughout movement of the platform with respect to the body portion.
In some embodiments, the ironing device further includes an actuator for moving the platform with respect to the body portion. The actuator is associated with the body portion and the platform to move the platform between a close position at which the platform is closely juxtaposed to or touching the body surface and an open position at which the platform is separated from the body surface sufficiently to allow insertion of fabric between the platform and the body surface. The actuator includes a trigger, a spring, and a gear assembly which are assembled to maintain the platform in an initial position. In one embodiment, the initial position is an open position that allows for fabric to be placed between the platform and body surface. In another embodiment, the initial position is a closed position at which the platform is closely juxtaposed to or touching the body surface.
In some embodiments, the actuator is removable from the body portion. In other embodiments, both the actuator and platform are removable from the body portion. The handheld ironing device may include a removable brush attachment that may be connected to the body portion upon removal of the actuator and the platform.
In certain embodiments of the present invention, on of the body surface or platform surface is a heating surface. In one embodiment, the body surface is a heating surface and the body portion further includes a heating element adapted to transfer heat to the heating surface. In this embodiment, the heating surface may be a sole plate. The handheld ironing device may further include a thermostat for controlling the temperature of the heating surface and a water reservoir for providing water to the heating element to facilitate the production of steam. Water may be selectively provided to the heating element.
Another embodiment of the present invention is a handheld ironing device comprising a housing including an elongate handle portion, a heating element disposed with the housing, a substantially flat sole plate forming an exterior surface of the housing (the heating element transferring heat to the sole plate), a gear assembly removably attached to the housing, a platform having a substantially flat platform surface connected to the gear assembly, and a trigger associated with the gear assembly. The trigger is capable of operating in conjunction with the gear assembly to displace the platform with respect to the housing. In this embodiment, the sole plate and the platform surface are initially in substantially parallel planes and displacement of the platform with respect to the sole plate is in a direction substantially perpendicular to the parallel planes.
Another embodiment of the present invention is a handheld ironing device comprising a body portion including a substantially flat heating surface, a platform having a substantially flat platform surface, and an actuator connecting the body portion to the platform and facilitating movement of the platform with respect to the body portion. The platform is coupled to the body portion such that the platform surface opposes the heating surface. In this embodiment, the movement of the platform with respect to the body portion provides substantially uniform pressure to an article disposed between the heating surface and the platform surface.
Yet another embodiment of the present invention is a handheld ironing device comprising a body portion having a substantially flat heating surface and a platform having a substantially flat platform surface. The platform is movably associated with the body portion such that the platform surface is substantially parallel to the heating surface when the surfaces are closely juxtaposed or when the surfaces touch.
Yet another embodiment of the present invention is a handheld ironing device comprising a body portion having a body surface, a platform having a platform surface and a liquid container for facilitating the production of a gas. The platform movably associated with the body portion such that the platform surface opposes the body surface.
Yet another embodiment of the present invention is a handheld ironing device comprising a body portion having a heating surface, a platform having a platform surface, and an actuator for moving the platform with respect to the body portion. In this embodiment, the platform and the actuator are capable of being removed form the body portion.
A second aspect of the present invention is a method of removing wrinkles from fabric. This method includes the steps of providing a handheld ironing device having a heating surface and a platform surface opposed to the heating surface, situating a fabric article between the heating surface and the platform surface, and moving the platform and heating surfaces together to press the fabric article with substantially uniform pressure between the heating surface and the platform surface. This method may further include the step of heating the heating surface to a desired temperature. The moving step may further include actuating and actuator to move the platform surface with respect to the heating surface. The method may also further include the steps of producing steam and removing lint or other debris from an article of fabric.
The present invention will be better understood in reading the following detailed description of preferred embodiments which are only examples of the invention herein, the detailed description to be taken together with the drawings of preferred embodiments, in which:
In describing the preferred embodiments of the subject matter illustrated and to be described with respect to the drawings, specific terminology will be used for the sake of clarity. However, the invention is not intended to be limited to any specific terms used herein, and it is to be understood that each specific term includes all technical equivalents which operate in a similar manner to accomplish a similar purpose.
Referring to the drawings, wherein like reference numerals represent like elements, there is shown in
Housing 12 also includes elongated handle 22 for allowing the easy gripping and manipulation of iron 10, and power cord 30 for supplying power to the aforementioned heating element. It should be noted that in other embodiments elongated handle 22 can be of any shape or size, which can include ergonomic designs that are constructed to better facilitate grabbing by a user. It is also contemplated that power cord 30 can be of any length and can be engaged with an appropriate power supply, including standard electrical outlets. Furthermore, it is also contemplated that power cord 30 can be constructed so that it is retractable or disposed of within housing 12. Finally, in other embodiments of the present invention iron 10 may not include power cord 30. In these embodiments, iron 10 would include other means of providing the electrical power needed to properly operate the heating element. For example, iron 10 may be adapted to operate with the use of rechargeable or lithium batteries.
As best shown in
Actuator 16 also includes groove 44 and lateral guides 45a and 45b, located on gear box walls 43a and 43b which define the exterior of gear box 42 (best shown in
Teeth portion 51 of first gear 50 mates with transition gear 52. Transition gear 52 is a circular gear which rotates about a transition gear pivot 55 extending between gear box walls 43a and 43b. Second gear 54 is a semi-circular gear having a teeth portion 57, which also mates with transition gear 52, and non-teeth portion 59 connected to trigger 17. Trigger pivot 60 is the connection at which trigger 17 and second gear 54 are pivotably connected to gear box 42. Trigger pivot 60 extends between gearbox walls 43a and 43b and allows for trigger 17 to rotate around an axis extending through trigger pivot 60. Finally, spring 56 is connected to and biases trigger 17 at trigger pivot 60. Spring 56 is a torsion spring having two ends, one end connected to trigger 17 and the other end contacting cylindrical member 62, which extends between gear box walls 43a and 43b. A force in direction 64 applied to trigger 17 causes spring 56 to coil and build up energy. Upon the removal of the force applied to trigger 17, spring 56 uncoils and returns trigger 17 to its initial position.
In operation, upon the application of a force, trigger 17 is rotated about trigger pivot 60, which axiomatically displaces second gear 54. This displacement of second gear 54 causes teeth portion 57 to contact transition gear 52 and cause such to rotate. In turn, transition gear 52 contacts teeth portion 51 of first gear 50. Upon contact, and through further movement of second gear 54 and transition gear 52, first gear 50 translates. As mentioned above, this translation occurs in a linear direction with respect to channels 46a and 46b. In turn, platform 14 translates in a similar direction. As was also detailed above, when a force is no longer applied to trigger 17, spring 56 uncoils and biases trigger 17 back into an initial position, thereby bringing second gear 54, transition gear 52, first gear 50, and platform 14 back into their initial positions. This operation can be performed successively.
In the preferred embodiment, platform surface 40 lies within a plane that is substantially parallel to the plane in which sole plate 18 lies. The above-discussed rotation of trigger 17, and the corresponding translation of movement to other elements within gear box 42, causes platform surface 40 to move in a direction that is substantially perpendicular to the plane of sole plate 18. In other words, at all times throughout rotation of trigger 17 and the corresponding movement of platform surface 40, platform surface 40 remains in a plain that is substantially parallel to the plane in which sole plate 18 lies. In other embodiments, platform surface 40 and sole plate 18 may lie in initial planes which are not substantially parallel to each other. Rather, platform surface 40 and sole plate 18 may initially be in non-parallel planes, but upon being closely juxtaposed or upon touching each other, platform surface 40 and sole plate 18 enter substantially parallel planes. Various initial positions and subsequent transition positions are contemplated throughout the movement of platform surface 40 with respect to sole plate 18.
While in the preferred embodiment platform surface 40 contacts sole plate 18 upon actuation of trigger 17 (best shown in
Finally, a preferred embodiment of the present invention includes a cradle 100 for capturing and holding iron 10. As shown in
The preferred embodiment of the present invention is shown in
Another aspect of the invention relates to a method for utilizing a handheld ironing device. A method according to a preferred embodiment of the present invention includes utilizing a handheld ironing device, such as the iron 10 discussed above, to press an article of fabric without the use of an ironing board. It is noted that the above discussed iron 10 can be configured so as to allow for its use with a separate ironing board. Furthermore, as shown above, it is also possible for iron 10 to be configured to operate in conjunction with brush attachment 70 to facilitate the removal of lint or other debris.
In a preferred embodiment of the method of the present invention, the preferred iron 10, as discussed above, is employed. The user plugs power cord 30 into a standard wall socket and allows sole plate 18 to acquire a desired temperature level. A signal that sole plate 18 has reached the desired temperature level may be included. Upon reaching this desired temperature, a wrinkled fabric article is selected (although non-wrinkled fabrics for which a user wishes to form a crease in can also be utilized) . A portion of this fabric article is placed between sole plate 18 and platform surface 40. Trigger 17 is then actuated towards elongated handle 22. In the preferred embodiment, a user can grasp iron 10 with one hand, while actuating trigger 17 with a finger of the same hand. This allows for easy manipulation of iron 10 and gives the user freedom of his/her other hand. Actuation of trigger 17 causes platform 14 and platform surface 40 to displace towards sole plate 18, thereby clamping the article of fabric therebetween. The amount of actuation of trigger 17 directly determines the amount of displacement of platform 14. In turn, the pressure applied to the article of fabric may vary depending upon the amount of actuation of trigger 17. As stated above, sole plate 18 and platform surface 40 are initially in substantially parallel planes, and relative movement of platform surface 40 occurs in a direction substantially perpendicular to these planes. Therefore, substantially uniform pressure can be applied to the fabric article clamped therebetween.
Upon achieving the desired pressing of the fabric material (which may take some time, or multiple actuations of trigger 17), the user releases trigger 17, which is automatically biased to its original position, thereby returning platform 14 and platform surface 40 to their respective original positions. In these positions, the portion of the fabric article can be removed and additional portions of the article can be pressed. This process can be successively performed until all portions of the fabric article are pressed or all desired areas are creased. Additionally, at any time during the operation of iron 10, a user may selectively press button 38 to produce a desired amount of steam. Such steam may aid in pressing process. Button 38 is preferably situated so that a finger of the one hand of the user can be used to press it. Finally, a user may remove platform 14 and actuator 16 from housing 12, by biasing switch 26 and sliding gear box 42 from slot 24. With platform 14 and actuator 16 removed from housing 12, brush attachment 70 can be placed on housing 12. This attachment can be utilized to remove lint or other debris, or to simply steam an article of fabric through the operation of button 38. It should be noted that housing 12, with platform 14 and actuator 16 removed therefrom, can also be utilized in a manner similar to that for which conventional irons are utilized. A method of this type is well known in the art.
