CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority from Canadian Patent Application No. 3,213,999 filed 22 Sep. 2023, the contents of which are hereby incorporated by reference.

TECHNICAL FIELD

The present disclosure relates to stencils, and in particular, the present disclosure relates to stencil sets used for painting designs on structures or vehicles.

BACKGROUND

Stencils are commonly used when a design or pattern is desired to be painted onto an item or structure. For example, if a certain design is to be painted on an item, this may be accomplished by attaching a stencil (containing a cut-out outline of the design) to the item and then applying paint onto the stencil. The cut-out portions of the stencil will allow paint to be transferred to the item, while the remainder of the stencil will prevent the transfer of paint, thus allowing the design to be painted, or applied, onto the item.

However, it is tedious and time-consuming to be continually attaching and removing the stencil from the item when the design is to be applied at multiple locations on the item or when the item is relatively large (compared to the stencil).

Therefore, there is a need for a stencil system that allows for convenient application of multiple designs or patterns on an item or structure. These and other objects will be better understood by reference to the description which follows.

DETAILED DESCRIPTION

Referring to FIGS. 1 to 3, the stencil assembly 10 in accordance with one embodiment comprises a handle 12 that is adapted to be gripped by a hand of a user. The handle 12 may be generally elongated and curved, as shown in FIG. 2. However, the handle 12 may also take on any suitable elongated shape. The handle 12 comprises first and second handle ends 14, 16.

The stencil assembly 10 further comprises a clamp assembly 18 extending proximate to the second handle end 16. The clamp assembly 18 comprises first and second portions 20, 22 that are pivotally connected together (at connection point 24).

The first portion 20 comprises a first clamp handle 26 and a first clamp member 28 extending from the first clamp handle 26. The second portion 22 comprises a second clamp handle 30 and a second clamp member 32 extending from the second clamp handle 30. The first clamp handle 26 may be fixedly attached to the handle 12. The second clamp handle 30 may comprise a handle surface 34 that is adapted to be pressed by the user.

The clamp assembly 18 further comprises a spring 36 that is connected to the first and second clamp handles 26, 30 and is adapted to bias the first and second clamp members 28, 32 together (i.e. when the clamp assembly 18 in a “closed” configuration, as shown in FIG. 2). When pressure is applied to the handle surface 34 (e.g. from the user pressing on the handle surface 34), the pressure causes the spring 36 to compress, causing the first and second portions 20, 22 to move pivotally at the connection point 24. This in turns causes the first and second clamp members 28, 32 to move apart from each other (i.e. transitioning the clamp assembly 18 into an “open” configuration). When pressure is no longer applied to the handle surface 34 (e.g. from the user no longer pressing on the handle surface 34), the release of pressure on the spring 36 biases the first and second clamp members 28, 32 together, transitioning the clamp assembly 18 back to the “closed” configuration.

Referring to FIGS. 3 and 4, the first clamp member 28 may comprise a first clamp surface 38 with a first leading edge 40, while the second clamp member 30 may comprise a second clamp surface 42 with a second leading edge 44. When the clamp assembly 18 is in the “closed” configuration, the first clamp surface 38 and the second clamp surface 42 engage with each other. In some embodiments, one or both of the first and second clamp surfaces 38, 42 comprise one or more grooves 46 extending from the first leading edge 40 and/or the second leading edge 44. Where the grooves 46 are present on both the first and second clamp surfaces 38, 42, the grooves 46 on the first clamp surface 38 may generally correspond with the grooves 46 on the second clamp surface 42 such that when the clamp assembly 18 is in the “closed” configuration, the grooves 46 on the first clamp surface 38 are generally aligned with the grooves 46 on the second clamp surface 42.

When the clamp assembly 18 is in the “closed” configuration, the grooves 46 may form channels 48 extending from the first and second leading edges 40, 44. For example, where the grooves 46 are present on both the first and second clamp surfaces 38, 42, the grooves 46 on the first clamp surface 38 may align with the grooves 46 on the second clamp surface 42 to define, at least in part, the channels 48. Alternatively, in some embodiments, where the grooves 46 are only present on one of the first and second clamp surfaces 38, 42, the channels 48 may be defined by, at least in part, the grooves 46 on one of the first and second clamp surfaces 38, 42 and the other one of the first and second clamp surfaces 38, 42.

In some embodiments, one or more of the channels 48 defined by the grooves 46 may have a diameter or width that are greater at least at some points away from the first and second leading edges 40, 44. For example, in the embodiment shown in FIGS. 3 and 4, a portion of some of the grooves 46 may be defined, at least in part, by a pair of generally parallel groove side walls 50 extending from the first and/or second leading edges 40, 44. The groove side walls 50 may be formed on the first and/or second clamp surfaces 38, 42. However, the grooves 46 may further comprise one or more cutout portions 52. At least a portion of the cutout portions 52 have a width greater than a width between the groove side walls 50. In the embodiment shown in FIGS. 3 and 4, the cutout portions 52 comprise a triangular shape; however, it is understood that other shapes (circles, rectangles, squares, other polygons) are also possible.

Referring again to FIGS. 3 and 4, one or more of the channels 48 defined by the grooves 46 may form a partial path within the first and/or second clamp surfaces 38, 42.

The stencil assembly 10 further comprises stencil attachments 54 that are adapted to engage with the channels 48. Referring to FIGS. 5 and 6, the stencil attachment 54 comprise a stencil design 56 (depicting a desired pattern or shape) and one or more attachment members 58 extending therefrom. For example, FIG. 5 depicts the stencil design 56 in the shape of a leaf; however, it is understood that other shapes, patterns, or designs are also possible. The attachment members 58 are adapted to fit, at least partially, within the channels 48. Accordingly, the attachment members 58 may have a shape that corresponds generally with the shape of the cutout portions 52. For example, in the embodiment shown in FIG. 5, the attachment member 58 comprises a stem 60 and a head 62. The stem 60 extends between the head 62 and the stencil design 56. The head 62 may have a shape that corresponds to that of the cutout portions 52. For example, in the embodiment shown in FIG. 5, the head 62 has a triangular shape generally corresponding to the shape of the cutout portion 32. One benefit of using a triangular shape is that rotation of the stencil attachment 54 within the channels 48 is prevented.

Other embodiments for the stencil attachments 54 are also possible. For example, referring to FIG. 6, the stencil attachment 54 may comprise a frame 64 onto which the stencil designs 56 may be attached.

Referring to FIG. 7, the operation of the stencil assembly 10 will now be described. The stencil assembly 10 initially has the clamp assembly 18 in the “closed” configuration, with no stencil attachments 54 attached to the clamp assembly 14. The user first applies pressure on the handle surface 34. This causes the first and second clamp surfaces 38, 42 to move apart from each other, thereby moving the clamp assembly 18 to the “open” configuration. One or more of the stencil attachments 54 are placed such that the stem 60 and the head 62 are located within the grooves 46, with the head 62 located within the cutout portions 52. The user then releases pressure on the handle surface 34, thereby causing the first and second clamp surfaces 38, 42 to bias towards each other, moving the clamp assembly 18 back to the “closed” configuration. Once the first and second clamp surfaces 38, 42 contact and engage with each other, the channels 48 are formed. Because of the configuration of the channels 48, the stencil attachments 54 are not able to move out of the channels 48 but are instead held in place when clamp assembly 18 is in the “closed” configuration. The user can then grip the handle 12 and place the stencil assembly 10 proximal to the object being painted and apply paint (e.g. through a paint spray, etc.).

In order to remove the stencil attachments 54, the user applies pressure to the handle surface 34, thereby moving the first and second clamp surfaces 38, 42 apart. The stencil attachments 54 can then be removed from the grooves 46.

In addition, stencil attachments 54 of differing sizes and configurations may also be used. For example, some stencil attachments 54 may be individual units, with each of the stencil attachments 54 attached to a single one of the channels 48. In other embodiments, a single one of the stencil attachments 54 may be used, with the frame 64 and multiple ones of the stencil designs 56 extending from the frame 64.

It will be appreciated by those skilled in the art that the preferred embodiment has been described in some detail but that certain modifications may be practiced without departing from the principles of the invention.
