The first ledge 24 further includes a first end 24c opposite to the first surface 21c of the body 21 of the anchor 20. The first ledge 24 defines a slot 24d at the intersection of the second surface 24b and the first end 24c. As illustrated in the figures, the first end 24c of the first ledge 24 of the anchor 20 is enlarged relative to the rest of the first ledge 24.

[0072] In another embodiment, the first end 24c may be convex with respect to the first surface 21c of the body 21 of the anchor 20. In yet another embodiment, the first end 24c may be a convex bulb with respect to the first surface 21c of the body 21 of the anchor 20. In yet another embodiment, the first end 24c may be bulbous with respect to the first surface 21c of the body 21 of the anchor 20. In one specific embodiment, the radius of first end 24c may be of about 0.075-0.175 inches.

[0073] Referring still to FIG. 7A, the second ledge 25 of the attachment end 23 includes a first surface 25a and a second surface 25b opposite to one another. The second ledge 25 further includes a first end 25c opposite the first surface 21c of the body 21 of the anchor 20. The second ledge 25 defines a passage 25d at the intersection of the first surface 25a and the first end 25c. Further, the first surface 25a of the second ledge 25 is continuous with the first side 23A of the attachment end 23.

[0074] The second ledge 25 further defines an inset 25e between the second surface 25b of the second ledge 25 and the second surface 21d of the body 21, and extending upwardly towards the first surface 25a of the second ledge 25. Because of the presence of inset 25e, second ledge 25 is thinner proximate body 21 than remote from body 21. Second ledge 25 may therefore be able to flex somewhat relative to body 21. The first end 25c of the second ledge 25 is enlarged relative to the rest of the second ledge 25.

[0075] In another embodiment, the first end 25c of the second ledge 25 may be convex with respect to the first side 23A of the attachment end 23. In yet another embodiment, the first end 25c may be a convex hook with respect to the first side 23A of the attachment end 23. In yet another embodiment, the first end 25c may be hooked with respect to the first side 23A of the attachment end 23. In this other embodiment, the length of the convex hook is of a length of about 0.1-0.4 inches. Further in this embodiment, the length between the first side 23A of the attachment end 23 and the passage 25d of the second ledge 25 is about 0.5-0.8 inches. Even further in this embodiment, the distance between the first end of 24c of the first ledge 24 and the first end 25c of the second ledge 25 is of about 0.25-0.6 inches.

[0076] The attachment end 23 of the anchor 20 is configured to detachably engage and is complementary to the protrusion 10C of the embed grate frame 2. Moreover, the attachment end 23 is selectively engageable with the protrusion 10C.

[0077] Having now described the embed grate frame 2 and the anchor 20 of grate frame assembly 1, a method of installing the grate frame assembly 1 at a worksite will now be described in greater detail. Embed grate frame 2 and a plurality of separate anchors 20 will be shipped to the worksite separately. The plurality of separate anchors 20 will then be engaged with the embed grate frame 2 at the worksite. Shipping these components separately helps to ensure that there is less opportunity for damage to the components before installation and also reduces shipping costs because the embed grate frame 2 occupies less space. The engagement of one anchor 20 of the plurality of anchors 20 with the embed grate frame 2 to form the grate frame assembly 1 will now be described in more detail below.

[0078] Referring now to FIG. 8A, the anchor 20 removably attached to the embed grate frame 2. More specifically, the attachment end 23 of the anchor 20 removably attached to the protrusion 10C of the embed grate frame 2.

[0079] The user may introduce the anchor 20 to the embed grate frame 2 by placing the first ledge 24 of the attachment end 23 of the anchor 20 atop the first flange 18 of the protrusion 10C of the main body 10A wherein the first flange 18 of the protrusion 10C is in the channel 23B of the attachment end 23. Referring now to FIG. 8B, once the first ledge 24 of the attachment end 23 is positioned, the user may press on the anchor in an arch motion away from the main body 10A of the embed grate frame 2 also depicted as arrow A on FIG. 8B to secure the attachment end 23 of the anchor 20 to the protrusion 10C of the embed grate frame 2. In particular, anchor 20 is snap-fittingly engaged with protrusion 10C.

[0080] Referring now to FIG. 8C, once the attachment end 23 of the anchor 20 is snap-fittingly secured onto the protrusion 10C of the embed grate frame 2, the following depicts the relationship between the attachment end 23 of anchor 20 and the protrusion 10C.

[0081] The first flange 18 of the protrusion 10C of the embed grate frame 2 is operably engaged with attachment end 23 of the anchor 20. Specifically, the first section 18a of the first flange 18 of the protrusion 10C is contiguous with the first end 24c of the first ledge 24 of the attachment end 23, wherein the recess 18d of the first flange 18 of the protrusion 10C is contiguous with the first end 24c of the first ledge 24 of the attachment end 23 of the anchor 20. The second section 18b of the first flange 18 of the protrusion 10C is contiguous with the second surface 24b of the first ledge 24 of the attachment end 23. The junction between the first section 18a and the second section 18b of the first flange 18 of the protrusion 10C is contiguous with the slot 24d of the first ledge 24 of the attachment end 23. Further, the peak of the second surface 18c of the first flange 18 of the protrusion 10C is contiguous with the first surface 25a of the second ledge 25 of the attachment end 23, wherein there is empty space ES (FIG. 8C) between second surface 18c of the first flange 18 of the protrusion 10C and the first side 23A of the attachment end 23.

[0082] Further, the second flange 19 of the protrusion 10C of the embed grate frame 2 is operably engaged with the second ledge 25 of the attachment end 23 of the anchor 20. The first end 19c of the second flange 19 of the protrusion 10C is contiguous with the first end 25c of the second ledge 25 of the attachment end 23. More specifically, the first section 19d of the first end 19c is contiguous with the passage 25d of the second ledge 25 of the attachment end 23. The second section 19e and the third section 19f of the first end 19c of the second flange 19 of the protrusion 10C is contiguous with the first end 25c of the second ledge 25 of the attachment end 23.

[0083] Further, when the protrusion 10C and the attachment end 23 are operably engaged, there is void space VS (FIG. 8C) extending from the first surface 25a of the second ledge 25 to the second edge 19b of the second flange 19 and between the channel 17c of the protrusion 10C and the first surface 25a of the second ledge 25 of the attachment end 23.

[0084] Having now described the engagement between the embed grate frame 2 and the anchor 20 to form the grate frame assembly 1, a method for installing the grate frame assembly 1 into a worksite will now be described.

[0085] Referring now to FIG. 8D, the user lowers the grate frame assembly 1 into the worksite. In particular, the worksite comprises a sidewalk S (FIG. 1) in which an opening has been defined. At least a portion of the opening is bounded and defined by the wall W. Concrete form CF is placed a distance away from wall W such that free space FS is defined between wall W and concrete form CF. It will be understood that if a square or rectangular grate frame assembly 1 is to be installed in sidewalk S, then the wall W defining the opening will be generally square or rectangular in configuration. Furthermore, the concrete form CF utilized to support the entire grate frame assembly 1 will similarly be square or rectangular in configuration.

[0086] When concrete form CF is in place, embed grate frame 2 is lowered into position such that leg 10B of embed grate frame 2 rests upon concrete form CF as will be discussed hereafter. It will be understood that anchors 20 may be engaged with embed grate frame 2 before embed grate frame 2 is lowered into the free space FS or after embed grate frame 2 is lowered into free space FS and/or seated on concrete form CF. The lowering of the embed grate frame 2 is depicted in FIG. 8D by arrows B. More specifically, the second region 14 of the leg 10B is configured to engage the concrete form CF. Even more specifically, the leg 10B is configured to engage an uppermost end of the concrete form CF. Particularly, the corner 10B of the leg 10B is configured to engage an uppermost end of the concrete form CF at the part of the concrete form CF furthest from the wall W. The first region 13 of leg 10B curves away from protrusion 10C and the corner 10B of leg 10B engages the uppermost corner of the concrete form CF that is located furthest from wall W. Once the leg 10C is placed atop the concrete form CF the main body 10B of the embed grate frame 2 is positioned where the main body 10B does not touch the concrete form CF.

[0087] In one specific embodiment, the leg of the embed grate frame may be differently configured from what is illustrated in the attached figures. For example, a first region of the leg may curve towards the protrusion and the corner between the first region and the second region may receive the uppermost corner of the concrete form CF which is closest to the wall W. In other embodiments, the leg may be of any configuration that can engage concrete form CF and help retain embed grate frame 2 in place within the free space FS.

[0088] Further, when the user lowers the grate frame assembly 1 into the worksite, the anchor 20 is configured to engage wall W. More specifically, the support end 22 of the anchor 20 is configured to engage wall W. Even more specifically, the junction between the first side 22d and the third section 22c of support end 22 contacts wall W and the junction between the second side 22e and the third section 22c of support end 22 contacts floor F. When the anchor 20 is engaged with the wall W and floor F, there is gap G between the wall W and the third section 22c of the support end 22 of the anchor 20.

[0089] The user fills the free space FS with compound material CM. Either before or after the compound material CM sets, i.e., dries and hardens, the user engages the bearing bars 3 with embed grate frame 2. Specifically, the first arm 11 and the second arm 12 of the main body 10A of the embed grate frame 2 is configured to receive the bearing bars 3 of the embed grate frame 2. Even more specifically, a lowermost region of the ends of the bearing bars 3 are seated on first side 11a of the first arm 11 and abut the second side 12b of the second arm 12. The bearing bars 3 may be welded or otherwise secured to embed grate frame 2. (It will be understood that in other embodiments, not illustrated herein, bearing bars 3 may simply rest upon first arm 11.) FIG. 8E shows the embed grate frame 2 and anchor 20 secured in place by compound material CM and bearing bars 3 engaged with embed grate frame 2.

[0090] FIGS. 9-12 illustrate a second embodiment of an embed grate frame 102. The anchor 20 described previously herein is adapted to be engaged with either of the embed grate frame 2 or the embed grate frame 102 and therefore will not be described in any further detail herein. It should be understood that embed grate frame 102 includes a first member 2A, a second member, a third member, and a fourth member similar to embed grate frame 2 which includes first member 2A, second member 2B, third member 2C, and fourth member 2D. Each of the first member 2A, the second member, the third member, and the fourth member of embed grate frame are identical in configuration to one another but are differently configured relative to the members 2A, 2B, 2C, and 2D

[0091] First member 2A of embed grate frame 102 comprises a main body 110A, a leg 110B, and a protrusion 110C. Main body 110A comprises a first arm 111 and a second arm 112. First member 2A of embed grate frame 102 is identical in structure and function to first member 2A of embed grate frame 2 first embodiment of the embed grate frame in all aspects except with respect to the configuration of the second arm 112. In view of this, the following discussion relates substantially entirely to the structure and function of second arm 112.

[0092] Referring now to FIGS. 10 and 11, the second arm 112 of the main body 110A includes a first side 112a and a second side 112b opposite one another. The second arm 112 further includes a first end 112c which extends between first side 112a and second side 112b. First end 112c is substantially parallel to the first side 111a of the first arm 111. The first end 112c of the second arm 112 is continuous with the first side 112a and the second side 112b of the second arm 112.

[0093] Referring now to FIGS. 12 and 12A the second arm 112 of the main body 110A may be generally an hourglass shape wherein the first side 112a and the second side 112b have a curve or are angled with respect to the first end 112c. The first side 112a and the second side 112b have wider portions at the top further from the first arm 111 and the end closer to the first arm 111 and narrow to a thinner portion 112d at around the middle of the second arm 112. The thinner portion 112d may be of a thickness around 0.05-0.25 inches.

[0094] In one specific embodiment, the second side 112b of the second arm 112 may be of a width, similar to width W2 (FIG. 5), of about 1-2 inches. Further, the first end 112c of the second arm 112 may be of a height, similar to height H2 (FIG. 5A) of about 0.1-0.3 inches. In yet another embodiment, the first side 112a, and the second side 112b of second arm 112 may have some curvature.

[0095] Referring to FIGS. 9 and 10, first member 2A comprises a main body 110A, a leg 110B, and a protrusion 110C. Leg 110B and protrusion 110C are integral with main body 110A and extend outwardly therefrom, as will be described later herein.

[0096] Main body 110A is generally L-shaped and includes a first arm 111 and a second arm 112 which intersect one another at a corner 110A. The intersection of the first arm 111 and the second arm 112 is at any angle which will allow bearing bars to be securely set into an area created by the intersection of the first arm 11 and the second arm 112. As illustrated, first arm 111 is orthogonal to second arm 112.

[0097] Referring now to FIGS. 10, 11, 12 and 12A, the first arm 111 includes a first side 111a opposite to a second side 111b. Second side 111b includes a first section 111b and a second section 111b. First section 111b and second section 111b are substantially aligned with one another. The first section 111b extends from corner 110A to leg 110B. The second section 111b extends from leg 110B to an end 111d of first arm 111. End 111d is substantially perpendicular to the first side 111a and the second side 111b and is the furthest most point on the first arm 111 from the corner 110A. The end 111d is further continuous with the first side 111a and the second side 111b. The first side 111a of the first arm 111 further defines a groove 111e therein. Groove 111e extends downwardly from the first side 111a to the second side 111b. As illustrated, the groove 111e is located closer to the end 111d of first arm 111 than to the corner 110A of the first arm 111 and the second arm 112. Groove 111e extends for substantially the entire length of first member 2A. Groove 111e is V-shaped in configuration. In other embodiments, groove 111e may be of a different configuration, for example, the groove may be concavely curved.

[0098] As shown in FIGS. 9, 10, 11, 12 and 12A, leg 110B extends outwardly from first arm 111 of main body 110A. In particular, leg 110B extends outwardly away from second side 111b of first arm 111. Leg 10B includes a first region 113 and a second region 114, which intersect one another at a corner 110B. The first region 113 is arcuately curved and includes a first surface 113a and a second surface 113b opposite to one another.

[0099] The first region 113 of the leg 110B is continuous with the second side 111b of the first arm 111 of the main body 110A. In particular, the first surface 113a of first region 113 is continuous with the first section 111b of second side 111b. The second surface 113b of the first region 113 of the leg 110B is continuous with the second section 111b of second side 111b of first arm 111.

[0100] The second region 114 of the leg 110B includes a first side 114a and a second side 114b opposite to one another, wherein both the first side 114a and the second side 114b are substantially parallel to the end 111d of the first arm 111 of the main body 110A. Second region 114 terminates in an end 116. The end 116 of the leg 110B is continuous with the first side 114a and second side 114b of the second region 114 of the leg 110B. The end 116 is substantially perpendicular to the first side 114a and the second side 114b.

[0101] The first region 113 and the second region 114 are integral with one another and the first surface 113a of the first region 113 and the first side 114a of the second region 114 intersect at the corner 110B.

[0102] Unless explicitly stated that a particular shape or configuration of a component is mandatory, any of the elements, components, or structures discussed herein may take the form of any shape.

[0103] Various inventive concepts may be embodied as one or more methods, of which an example has been provided. The acts performed as part of the method may be ordered in any suitable way. Accordingly, embodiments may be constructed in which acts are performed in an order different than illustrated, which may include performing some acts simultaneously, even though shown as sequential acts in illustrative embodiments.

[0104] While various inventive embodiments have been described and illustrated herein, those of ordinary skill in the art will readily envision a variety of other means and/or structures for performing the function and/or obtaining the results and/or one or more of the advantages described herein, and each of such variations and/or modifications is deemed to be within the scope of the inventive embodiments described herein. More generally, those skilled in the art will readily appreciate that all parameters, dimensions, materials, and configurations described herein are meant to be exemplary and that the actual parameters, dimensions, materials, and/or configurations will depend upon the specific application or applications for which the inventive teachings is/are used. Those skilled in the art will recognize, or be able to ascertain using no more than routine experimentation, many equivalents to the specific inventive embodiments described herein. It is, therefore, to be understood that the foregoing embodiments are presented by way of example only and that, within the scope of the appended claims and equivalents thereto, inventive embodiments may be practiced otherwise than as specifically described and claimed. Inventive embodiments of the present disclosure are directed to each individual feature, system, article, material, kit, and/or method described herein. In addition, any combination of two or more such features, systems, articles, materials, kits, and/or methods, if such features, systems, articles, materials, kits, and/or methods are not mutually inconsistent, is included within the inventive scope of the present disclosure.

[0105] All definitions, as defined and used herein, should be understood to control over dictionary definitions, definitions in documents incorporated by reference, and/or ordinary meanings of the defined terms.

[0106] The articles a and an, as used herein in the specification and in the claims, unless clearly indicated to the contrary, should be understood to mean at least one. The phrase and/or, as used herein in the specification and in the claims (if at all), should be understood to mean either or both of the elements so conjoined, i.e., elements that are conjunctively present in some cases and disjunctively present in other cases. Multiple elements listed with and/or should be construed in the same fashion, i.e., one or more of the elements so conjoined. Other elements may optionally be present other than the elements specifically identified by the and/or clause, whether related or unrelated to those elements specifically identified. Thus, as a non-limiting example, a reference to A and/or B, when used in conjunction with open-ended language such as comprising can refer, in one embodiment, to A only (optionally including elements other than B); in another embodiment, to B only (optionally including elements other than A); in yet another embodiment, to both A and B (optionally including other elements); etc. As used herein in the specification and in the claims, or should be understood to have the same meaning as and/or as defined above. For example, when separating items in a list, or or and/or shall be interpreted as being inclusive, i.e., the inclusion of at least one, but also including more than one, of a number or list of elements, and, optionally, additional unlisted items. Only terms clearly indicated to the contrary, such as only one of or exactly one of, or, when used in the claims, consisting of, will refer to the inclusion of exactly one element of a number or list of elements. In general, the term or as used herein shall only be interpreted as indicating exclusive alternatives (i.e. one or the other but not both) when preceded by terms of exclusivity, such as either, one of, only one of, or exactly one of. Consisting essentially of, when used in the claims, shall have its ordinary meaning as used in the field of patent law.

[0107] As used herein in the specification and in the claims, the phrase at least one, in reference to a list of one or more elements, should be understood to mean at least one element selected from any one or more of the elements in the list of elements, but not necessarily including at least one of each and every element specifically listed within the list of elements and not excluding any combinations of elements in the list of elements. This definition also allows that elements may optionally be present other than the elements specifically identified within the list of elements to which the phrase at least one refers, whether related or unrelated to those elements specifically identified. Thus, as a non-limiting example, at least one of A and B (or, equivalently, at least one of A or B, or, equivalently at least one of A and/or B) can refer, in one embodiment, to at least one, optionally including more than one, A, with no B present (and optionally including elements other than B); in another embodiment, to at least one, optionally including more than one, B, with no A present (and optionally including elements other than A); in yet another embodiment, to at least one, optionally including more than one, A, and at least one, optionally including more than one, B (and optionally including other elements); etc.

[0108] While components of the present disclosure are described herein in relation to each other, it is possible for one of the components disclosed herein to include inventive subject matter, if claimed alone or used alone. In keeping with the above example, if the disclosed embodiments teach the features of A and B, then there may be inventive subject matter in the combination of A and B, A alone, or B alone, unless otherwise stated herein.

[0109] As used herein in the specification and in the claims, the term effecting or a phrase or claim element beginning with the term effecting should be understood to mean to cause something to happen or to bring something about. For example, effecting an event to occur may be caused by actions of a first party even though a second party actually performed the event or had the event occur to the second party. Stated otherwise, effecting refers to one party giving another party the tools, objects, or resources to cause an event to occur. Thus, in this example a claim element of effecting an event to occur would mean that a first party is giving a second party the tools or resources needed for the second party to perform the event, however the affirmative single action is the responsibility of the first party to provide the tools or resources to cause said event to occur.

[0110] When a feature or element is herein referred to as being on another feature or element, it can be directly on the other feature or element or intervening features and/or elements may also be present. In contrast, when a feature or element is referred to as being directly on another feature or element, there are no intervening features or elements present. It will also be understood that, when a feature or element is referred to as being connected, attached or coupled to another feature or element, it can be directly connected, attached or coupled to the other feature or element or intervening features or elements may be present. In contrast, when a feature or element is referred to as being directly connected, directly attached or directly coupled to another feature or element, there are no intervening features or elements present. Although described or shown with respect to one embodiment, the features and elements so described or shown can apply to other embodiments. It will also be appreciated by those of skill in the art that references to a structure or feature that is disposed adjacent another feature may have portions that overlap or underlie the adjacent feature.

[0111] Spatially relative terms, such as under, below, lower, over, upper, above, behind, in front of, and the like, may be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if a device in the figures is inverted, elements described as under or beneath other elements or features would then be oriented over the other elements or features. Thus, the exemplary term under can encompass both an orientation of over and under. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly. Similarly, the terms upwardly, downwardly, vertical, horizontal, lateral, transverse, longitudinal, and the like are used herein for the purpose of explanation only unless specifically indicated otherwise.

[0112] Although the terms first and second may be used herein to describe various features/elements, these features/elements should not be limited by these terms, unless the context indicates otherwise. These terms may be used to distinguish one feature/element from another feature/element. Thus, a first feature/element discussed herein could be termed a second feature/element, and similarly, a second feature/element discussed herein could be termed a first feature/element without departing from the teachings of the present invention.

[0113] An embodiment is an implementation or example of the present disclosure. Reference in the specification to an embodiment, one embodiment, some embodiments, one particular embodiment, an exemplary embodiment, or other embodiments, or the like, means that a particular feature, structure, or characteristic described in connection with the embodiments is included in at least some embodiments, but not necessarily all embodiments, of the invention. The various appearances an embodiment, one embodiment, some embodiments, one particular embodiment, an exemplary embodiment, or other embodiments, or the like, are not necessarily all referring to the same embodiments.

[0114] If this specification states a component, feature, structure, or characteristic may, might, or could be included, that particular component, feature, structure, or characteristic is not required to be included. If the specification or claim refers to a or an element, that does not mean there is only one of the element. If the specification or claims refer to an additional element, that does not preclude there being more than one of the additional element.

[0115] As used herein in the specification and claims, including as used in the examples and unless otherwise expressly specified, all numbers may be read as if prefaced by the word about or approximately, even if the term does not expressly appear. The phrase about or approximately may be used when describing magnitude and/or position to indicate that the value and/or position described is within a reasonable expected range of values and/or positions. For example, a numeric value may have a value that is +/0.1% of the stated value (or range of values), +/1% of the stated value (or range of values), +/2% of the stated value (or range of values), +/5% of the stated value (or range of values), +/10% of the stated value (or range of values), etc. Any numerical range recited herein is intended to include all sub-ranges subsumed therein.

[0116] Additionally, the method of performing the present disclosure may occur in a sequence different than those described herein. Accordingly, no sequence of the method should be read as a limitation unless explicitly stated. It is recognizable that performing some of the steps of the method in a different order could achieve a similar result.

[0117] In the claims, as well as in the specification above, all transitional phrases such as comprising, including, carrying, having, containing, involving, holding, composed of, and the like are to be understood to be open-ended, i.e., to mean including but not limited to. Only the transitional phrases consisting of and consisting essentially of shall be closed or semi-closed transitional phrases, respectively.

[0118] To the extent that the present disclosure has utilized the term invention in various titles or sections of this specification, this term was included as required by the formatting requirements of word document submissions pursuant the guidelines/requirements of the United States Patent and Trademark Office and shall not, in any manner, be considered a disavowal of any subject matter.

[0119] In the foregoing description, certain terms have been used for brevity, clearness, and understanding. No unnecessary limitations are to be implied therefrom beyond the requirement of the prior art because such terms are used for descriptive purposes and are intended to be broadly construed.

[0120] Moreover, the description and illustration of various embodiments of the disclosure are examples and the disclosure is not limited to the exact details shown or described.
