Patent Application
20150075046
The present application claims priority from Australian Provisional Patent Application No. 2012901018 filed 14 Mar. 2012, the entire contents of which are incorporated herein by reference.
The present invention relates to a retainer device for a picture frame assembly, and in particular, to a retainer device for a picture frame assembly that assists in holding a backing of a picture frame in position.
Picture frame assemblies come in a variety of types and sizes. Picture frames generally comprise a frame or border having a recess within which is received a picture, such as a photograph. The frame essentially forms a dual purpose, namely to provide an aesthetic border around the picture and to provide a structure to hold and retain the picture in a position for display.
Most picture frame assemblies generally comprise a rigid body having a central recess into which the picture is received. A window region is generally provided in the body of the frame assembly that extends over the recess to provide a means for viewing the picture. To provide an enclosed setting, the window may have a glass or plastic cover to protect the picture positioned underneath. A backing member in the form of a piece of plywood or similar material is located within the recess to be positioned at the rear of the picture when the picture is located within the frame assembly. The backing member is generally shaped to conform to the shape of the recess so that the backing member acts to sandwich the picture between the backing member and the frame/glass, so that it is retained in position for viewing.
In order to keep the backing member in position, a variety of retainer devices have been proposed. Generally the retaining elements are in the form of metal pins or nails that are inserted into the body of the frame assembly so as to extend into the recess behind the backing member. The pins then act to engage with the rear of the backing member so as to prevent it from falling out of the recess. Typically, the retaining members are inserted into the body of the frame assembly by way of tool such as a staple gun or the like, such that the pin penetrates the body a desired depth, typically around 6-7 mm, to prevent the pin inadvertently falling out of the frame assembly.
Whilst existing retaining members of the type described above have proven adequate in retaining a backing member of a picture frame assembly in position, such devices cannot be used in all situations, especially where the frame assembly is thin and/or the material of the frame is brittle. In such situations, the act of inserting the pin into the body of the frame for use may result in the pin penetrating through the walls and damaging the frame assembly, which is highly undesirable.
Thus, there is a need to provide a retainer device for a picture frame assembly that is capable of retaining a backing of a picture frame assembly in position, and which can be used in variety of applications, especially those applications where the walls of the picture frame assembly are thin and easily damaged by conventional retainer members.
The above references to and descriptions of prior proposals or products are not intended to be, and are not to be construed as, statements or admissions of common general knowledge in the art. In particular, the above prior art discussion does not relate to what is commonly or well known by the person skilled in the art, but assists in the understanding of the inventive step of the present invention of which the identification of pertinent prior art proposals is but one part.
The invention according to one or more aspects is as defined in the independent claims. Some optional and/or preferred features of the invention are defined in the dependent claims.
Accordingly, in one aspect of the invention there is provided a retainer device for a picture frame assembly, the picture frame assembly having a body with a recess for receiving an item for display and a backing member configured to be positioned behind said item to retain the item within the recess, the retainer device comprising:
In an embodiment, the one or more engagement members are teeth are formed on an underside of the head portion and are configured to penetrate into the body upon application of a force to the head portion. The one or more teeth may have a length of approximately 2 mm.
The retainer device may be mounted to extend substantially perpendicular to a rebate formed in the body.
A weakened region may be formed in the elongate tail portion adjacent the head portion to facilitate bending movement of the elongate tail portion with regard to the head portion.
The weakened region may be formed by forming an elongate slot through the elongate tail portion at the junction where the head portion and the elongate tail portion meet.
According to a second aspect, the present invention provides A picture frame comprising:
The invention may be better understood from the following non-limiting description of preferred embodiments, in which:
Preferred features of the present invention will now be described with particular reference to the accompanying drawings. However, it is to be understood that the features illustrated in and described with reference to the drawings are not to be construed as limiting on the scope of the invention.
The present invention will be described below in relation to a conventional picture frame assembly of the type having a frame body defining a central recess into which a picture, such as a photograph or the like is received and positioned for display. The recess has a rebate formed about the perimeter thereof, which acts as a means for receiving a backing member to retain the picture in position. In order to complete the assembly, a glass panel or window is located in the recess to provide a means for viewing the picture from a front surface of the picture frame assembly. It will be appreciated that the present invention could equally be applied to a variety of different types of picture frame assemblies, and still fall within the scope of the present invention.
Referring to
Around an outer rear edge of the recess 13, there is provided a rebate 14. The rebate 14 in the form of a stepped edge that defines a ledge positioned below the surface of the rear of the body 12. A glass panel 16 is configured to be received within the recess 13 such that it is supported at its periphery by the rebate 14. The glass panel 16 acts as a window or viewing area through which a picture (not shown) can be viewed when the picture frame assembly 10 is in an upright manner.
The picture (not shown) may be a print or photograph having a visual display formed on a surface thereof. The picture is typically placed on the glass panel 16 such that the visual display is against the glass panel and centred as desired by a user. Once positioned in such a manner, a backing member 15 is positioned within the recess 13 so as to be located behind the picture. The backing member 15 has a shape that substantially conforms to the recess 13 and functions to hold the picture in position against the glass panel 16.
In order to retain the backing member 15 in position within the recess 13, a plurality of retainer devices 20 are provided. The retainer devices 20 are mounted to an inside wall of the body 12 at predetermined positions about the recess 13. In the embodiment as shown in
An embodiment of a retainer device in accordance with a preferred aspect of the present invention is shown in isolation in
In order to fix the device 20 in position, the device 20 is positioned against the wall of the body 12 and a force is applied thereto, by way of a hammer, press or the like, to cause the teeth 23 to penetrate into the body 12. Each of the teeth 23 has a length of approximately 2 mm such that the device 20 can be used in applications where the wall of the body 12 is very thin. In order to facilitate secure engagement between the device 20 and the body 12, the teeth 23 may be configured so as to diverge away from each other, such that when the teeth penetrate the body 12 a degree of lateral force is created between the teeth 23.
The device 20 is typically made from a metal such as an steel or the like, and the teeth may be formed by punching a hole 21 in the head portion 22. In this regard, the teeth 23 are formed as a residual of the punching process. However, it will be appreciated that the teeth may be formed by a variety of other means and still fall within the scope of the present invention.
The tail portion 24 extends from the head portion 22 and has a length substantially greater than the length of the head portion 22. In a preferred form, the tail portion has a length of approximately 9.5 mm and the head portion 22 has a length of approximately 5.5 mm. A slot 25 is formed in the tail portion 24 at a region proximal the head portion to provide a region of reduced strength at or adjacent to the junction between the head portion 22 and the tail portion 24. The region of reduced strength enables the tail portion 24 to be bent about axis A-A with respect to the head portion, in a manner to be described in more detail below.
Referring to
This arrangement is shown in
As is shown in
It will be appreciated that the retainer device 20 of the present invention can be employed without the need for dedicated application devices and stapler guns and can be merely press fitted into position on the frame body 12. Due to the nature of the teeth provided on the retainer device the device can be employed in situations where the material of the frame body is made from a thin material, without fear of damage to the structure of the frame assembly. Thus, the retainer device of the present invention provides a simple yet effective alternative to conventional nail and pin arrangements used for retaining a backing of a picture frame in position.
