DESCRIPTION OF SPECIFIC EMBODIMENTS OF THE INVENTION

(18) The present invention, in some embodiments thereof, relates to an assembly for attaching decorative objects to a vertical surface, and more particularly, but not exclusively, to a wall hanging decorative assembly including a flexible strip with a removable adhesive and a non-adhesive gap.

(19) Before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not necessarily limited in its application to the details of construction and the arrangement of the components and/or methods set forth in the following description and/or illustrated in the drawings and/or the Examples. The invention is capable of other embodiments or of being practiced or carried out in various ways.

(20) Referring to FIGS. 3A-3D, embodiments of a decorative object assembly for attachment to a vertical surface are shown, in a cross-sectional or lateral view. Referring first to FIG. 3A, assembly 10 includes attachment assembly 11 and decorative block 12. Decorative block 12 may be any three-dimensional object suitable to be hung on a vertical surface. Decorative block 12 may be substantially planar. In one exemplary embodiment, decorative block 12 is a polystyrene foam 8?8 wall tile with a picture printed thereon. Alternatively, decorative block 12 is any other object that is hung onto a vertical surface, such as a picture printed onto cardboard, canvas, or poster board; or a framed art picture or painting; or an art work made of synthetic fabric, textile, paper, foam, glass, wood, or clay art. The vertical surface onto which the decorative block 12 may be hung may be, for example, a wall, a door, or a window.

(21) The attachment assembly 11 includes flexible planar strip 18. In the embodiment of FIG. 3A, flexible planar strip 18 is made of a thermoplastic polymer, such as polyethylene terephthalate or polypropylene. Flexible planar strip 18 defines an upper edge parallel to the upper edge of the decorative block 12, and a lower edge parallel to the lower edge of the decorative block 12. As used in the pending disclosure, the terms parallel to the upper edge and parallel to the lower edge describe the general orientation of the upper edge and lower edge of the flexible planar strip, and are not meant to restrict the assembly 10 to orientations that are exactly parallel.

(22) Flexible planar strip 18 is oriented in a vertical direction between the upper and lower edges thereof. As used in this disclosure, the term vertically upward refers to a direction toward the upper edge of planar strip 18, and the term vertically downward refers to a direction toward the lower edge of flexible planar strip 18.

(23) First layer of adhesive 20 extends vertically downward from the upper edge of flexible planar strip 18. The area of the flexible planar strip 18 onto which the first layer of adhesive 20 is attached is referred to herein as the upper vertical section. First layer of adhesive 20 is a removable adhesive, such as a pressure-sensitive adhesive. In one exemplary embodiment, first layer of adhesive 20 is the removable adhesive that is incorporated into RemoOne? removable adhesive strips.

(24) Attachment mechanism 14 extends vertically upward from the lower edge of flexible planar strip 18, and occupies a lower vertical section of the flexible planar strip. In the embodiment of FIG. 3A, attachment mechanism 14 is a mechanical attachment mechanism that cooperates with a corresponding attachment mechanism in decorative block 12, as will be described further below.

(25) A gap portion is defined on the flexible planar strip 18 in between the upper vertical section and the lower vertical section. The gap portion has neither an adhesive nor an attachment mechanism.

(26) FIG. 3B depicts a second embodiment of a decorative object assembly 110. Decorative object assembly 110 is similar in most respects to decorative object assembly 10, and accordingly similar components are assigned similar reference numerals, except that the reference numerals are preceded by a 1, as shown in the element first layer of adhesive 120. Attachment assembly 111 differs from attachment assembly 11, in that, instead of a mechanical attachment mechanism, second layer of adhesive 116 extends vertically upward from the lower edge of flexible planar strip 118. Second layer of adhesive 116 is a permanent adhesive, and may be any permanent adhesive known to those of skill in the art, for example, a solvent coated adhesive. Second layer of adhesive 116 serves as an attachment mechanism for attaching the flexible planar strip 118 to the decorative block 12.

(27) FIG. 3C depicts a third embodiment of a decorative object assembly 210. Decorative object assembly 210 is similar in most respects to decorative object assembly 10, and accordingly similar components are assigned similar reference numerals, except that the reference numerals are preceded by a 2 as shown in the elements first layer of adhesive 220 and attachment mechanism 214. Attachment assembly 211 differs from attachment assembly 11, in that in place of a flexible planar strip made of a thermoplastic polymer, such as polyethylene terephthalate or polypropylene, the flexible planar strip 219 is made of ethylene-vinyl acetate (EVA) foam. A film layer 221 is attached to the EVA foam planar strip 219. Film layer 221 may be made of polyethylene terephthalate or polypropylene. However, film layer 221 is very thin in comparison to flexible planar strips 18, 118. Film layer 221 provides structural support for the EVA foam planar strip 219. In addition, film layer 221 prevents the EVA foam from being pulled apart and losing its original shape or surface.

(28) FIG. 3D depicts a fourth embodiment of a decorative object assembly 310. Decorative object assembly 310 is similar in most respects to the prior embodiments, and accordingly similar components are assigned similar reference numerals, except that the reference numerals are preceded by a 3 as shown in the element first layer of adhesive 320. Attachment assembly 311 includes a second layer of adhesive 316, identical to second layer of adhesive 116. In addition, attachment assembly 311 includes an EVA foam flexible planar strip 319 and a film layer 321, identical to planar strip 219 and film layer 221.

(29) The use of polyethylene terephthalate, polypropylene, or EVA foam as the material for the flexible planar strip 18,118, 219, 319 is merely exemplary. Any other material may similarly be used for the flexible planar strip 18, 118, 219, 319, so long as it is sufficiently strong to support the decorative object 12, 112, 212, 312, and sufficiently flexible to flex when the decorative object 12, 112, 212, 312 is removed from the vertical surface, in the manner described below.

(30) Referring now to FIG. 4, a method for removing a decorative object assembly from a vertical surface is illustrated. While embodiment shown in FIG. 4 is that of FIG. 3A, the method depicted in FIG. 4 is equally applicable to any of the embodiments of FIGS. 3B-3D. As shown in the left frame of FIG. 4, first layer of adhesive 20 is releasably attached to a vertical surface 50. Thus, at this stage, decorative object 12 is releasably hung onto the vertical surface 50. In the middle frame of FIG. 4, a user begins to pull the decorative object 12 off of vertical surface 50, by applying a horizontal and upward removal force onto the bottom of the decorative object 12. Instead of the removal force being transferred directly onto the first layer of adhesive 20, as in the prior art depicted in FIG. 1, the removal force is initially applied on the flexible planar portion 18. As shown in the middle frame of FIG. 4, the removal force causes the flexible planar strip 18 to flex, beginning at the gap portion, while the first layer of adhesive 20 remains completely attached to the vertical surface. As shown in the rightmost frame of FIG. 4, continued horizontal and upward movement causes the upward vertical portion of the flexible planar strip to flex. This flexing, in turn, causes the first layer of adhesive 20 to peel off of the vertical surface 50 in a bottom-to-top direction, while the flexible planar strip remains flexed.

(31) Advantageously, the adhesive detaches gradually from the vertical surface 50, reducing the pull strength required to remove the decorative object assembly 10. This, in turn, reduces the stress on a wall surface, and decreases the likelihood of damage to the wall. In addition, the removal is performed in with a simple and ergonomically intuitive motion.

(32) Factors that influence the force required to remove a decorative object from a vertical surface, according to embodiments of the invention, include: the material of the flexible planar strip, the thickness of the flexible vertical strip, and the length of the gap section. The interplay of these factors is illustrated in FIGS. 5A and 5B.

(33) As shown in FIGS. 5A and 5B, for each of the embodiments of attachment assembly 11, 111, 211, 311, the flexible planar strip 18, 118, 219, 319 is divided into three vertical sections, delineated as A, B, and C. Section A is the upper vertical section, on which the removable adhesive is adhered. Section C is the lower vertical section, on which either the mechanical attachment mechanism is formed, or on which the permanent adhesive is adhered. Section B is the gap section, on which no adhesive is adhered.

(34) The following criteria influence the absolute and relative lengths of sections A, B, and C. With respect to section A, the length of section A directly correlates to the amount of removable adhesive that is used, and thus directly affects the strength of a bond between the removable adhesive and a vertical surface. This, in turn, can be selected to vary depending on the weight of the decorative object. The larger the dimension of upper vertical section A, the more adhesive that is used per weight of decorative object.

(35) With respect to dimension C, the length of dimension C depends on the type of permanent adhesive used. In general, it is advantageous to use the minimal possible amount of permanent adhesive, so long as there is no risk of detachment of the decorative object from the flexible planar strip.

(36) The optimal length of the gap section, or dimension B, depends on the flexibility and thickness of the carrier material forming the flexible planar strip. A more flexible material allows for a smaller B dimension, and a more rigid material allows for a larger B dimension.

(37) For example, when the flexible planar strip is made of 0.3 mm thick polyethylene terephthalate (PET), it was determined that: a gap section of 0-3 mm increases significantly the peeling strength needed. A gap section of 4-7 mm was optimal. A gap section of more than 8 mm resulted in a bad user experience, because the picture is lifted far from the wall before the peeling is started, and the user has to peel the frame to complete the peeling. Thus, for flexible planar strips made of PET, an optimal vertical length of the gap section is approximately between 10 and 25 times a thickness of the flexible planar strip.

(38) In another example, the flexible planar strip is made of 1/16 inch thick EVA foam. For flexible planar strips made of EVA foam, an optimal vertical length of the gap section is between 2 and 4 times a thickness of the flexible planar strip. In one preferred embodiment, the flexible planar strip made of 1/16 inch thick EVA foam, and the total combined length of sections A, B, and C is 1.4 inches. Section A is 1.0 inches long, section B is 0.15 inches long, and section C is 0.25 inches long.

(39) The width of the flexible planar strip can be customized to the width of the decorative object that it supports. For example, a flexible planar strip that is used to support an 8?8 decorative block may be 7.5 inches wide.

(40) FIGS. 6A and 6B depict additional elements that may be included in the adhesive assemblies 11, according to embodiments of the invention. The elements depicted in FIGS. 6A and 6B may also be incorporated into adhesive assemblies 211. FIG. 6A depicts the attachment assembly 11 prior to attachment of the flexible planar strip 18 to the first layer of adhesive 20, and FIG. 6B depicts the attachment assembly 11 after attachment of the flexible planar strip 18 to the first layer of adhesive 20. As shown in FIGS. 6A and 6B, a foam pad 22 may be disposed between first layer of adhesive 20 and flexible planar strip 18. In an exemplary embodiment, foam pad 22 is 1/16 thick. When a decorative object 10 is mounted against a wall, the foam pad 22 absorbs minor inconsistencies in a surface of the wall. The foam pad 22 thereby reduces the chance of separation of the first layer of adhesive from the wall due to surface bumps.

(41) Foam pad 22 is adhered to flexible planar strip 18 with third layer of adhesive 24. Third layer of adhesive 24 is a permanent adhesive, such as a solvent-based adhesive or any other type of permanent adhesive known to those of skill in the art. Removable siliconized liner 26 is adhered onto the vertical surface-facing side first layer of adhesive 20. Liner 26 may be siliconized on both sides thereof, so that it may be removed and reapplied onto first layer of adhesive 20 from either side. Liner 26 serves to protect removable adhesive 20 and prevent it from accidentally sticking onto surfaces.

(42) FIGS. 7, 8, and 9A-9B depict one embodiment of a mechanical attachment mechanism between attachment assembly 11 and decorative object 12, according to embodiments of the invention. The descriptions of FIGS. 7-9B are also applicable to attachment assembly 211 and decorative object 212. In FIG. 7, a wall-facing side of the decorative object 12 includes a frame 28. A visible portion 32 of attachment assembly 11, which includes first layer of adhesive 20, is attached to the decorative object 12. The frame 28 defines a border around central interior portion 30 and visible portion 32.

(43) Referring to FIG. 8, attachment mechanism 14 includes holes 34 in the lower vertical section. The holes 34 may be formed, for example, with a die cutting machine. Visible portion 32 may also include finger lift 36, which protrudes laterally beyond the flexible planar strip 18. Finger lift 36 may be grasped by a user when mechanically attaching the attachment mechanism to the decorative block.

(44) As shown in FIGS. 9A and 9B, a slot 40 is formed within the frame 28. Slot 40 contains protrusions 42, which are aligned with the corresponding holes 34 in the lower vertical section. To attach the attachment assembly 11 to the decorative object 12, a user slides the lower vertical section into the slot 40, and clicks the holes 34 over the protrusions 42. When thus attached, the visible portion 32 lays flat against the decorative object 12.

(45) The above-described mechanical attachment mechanism is merely exemplary, and other forms of mechanical attachment may be employed, as is known to those of skill in the art.

(46) FIGS. 10A and 10B depict additional elements that may be included in the adhesive assemblies 111, according to embodiments of the invention. The elements depicted in FIGS. 10A and 10B may also be incorporated into adhesive assemblies 311. FIG. 10A depicts the attachment assembly 111 prior to attachment of the flexible planar strip 118 to the first layer of adhesive 120, and FIG. 10B depicts the attachment assembly 111 after attachment of the flexible planar strip 118 to the first layer of adhesive 120. FIGS. 10A and 10B include foam pad 122, third layer of adhesive 124, and siliconized liner 126, which are equivalent to foam pad 22, third layer of adhesive 124, and siliconized liner 26, described above.

(47) Foam pad 122 is depicted as extending along the entire length of flexible planar strip 118, so that, when the decorative object 110 is mounted against the wall, a portion of the foam pad 122 directly abuts the wall. This configuration may further allow the foam pad 122 to absorb minor inconsistencies in a surface of the wall. This configuration is also possible in the embodiment of FIGS. 6A and 6B, and vice versa.

(48) The main difference between the embodiment of FIGS. 6A and 6B, versus the embodiment of FIGS. 10A and 10B, is that the attachment assembly 111 includes second layer of adhesive 116.

(49) As shown in FIG. 11, attachment assembly 111 is attached to the wall-facing side of decorative block 112, by applying second layer of adhesive 116. Because attachment assembly 111 is attached to decorative block 112 is with the second layer of adhesive 116, decorative block 112 is frameless. Following the attachment, visible portion 132 protrudes from the face of decorative block 112.

(50) In the embodiments of FIGS. 3C and 3D, in which the flexible planar strip 219, 319 is made of EVA foam, the EVA foam strip 219, 319, also absorbs minor inconsistencies in a surface of the wall, similar to foam pads 22, 122. In these embodiments, the aesthetics of the adhesive assemblies 211, 311 are improved, as a user sees only a single, whole piece of foam, rather than seeing a film with a piece of foam over it.

(51) It is expected that during the life of a patent maturing from this application many types of adhesive and many suitable polymeric and foam materials for flexible planar strips will be developed and the scope of the terms adhesive, polymer, and foam is intended to include all such new technologies a priori.
