The present invention relates to a new manner for assembly and quick disassembly, if required, of housing halves of toys (defining a cavity therebetween) and to a tool designed to easily and quickly disassemble toys comprised of housing halves or shells which otherwise, i.e, according to the prior art, are secured together with screws. The present invention relates to toy housings assembled by means of one or more snap joints formed of a T shaped member and a pair of parallel and resilient walls with opposed apertures which will snap around the outside edges of the T, to hold the two halves of the housing together. The present invention relates to a new manner of creating and manufacturing housing halves for a plastic toy housing and a method of easily and quickly assembling the same and then disassembling, if required. A tool used in the disassembly is disclosed.
Children's toys are often comprised of multiple plastic and mating components, very commonly these are plastic housing halves which mate together, are held together with screws and, yet, as a consequence take time to assemble and time to disassemble, if repair or replacement of components (batteries, wheels, spools, etc.) within the housing is required. In the prior art, to affix the multiple plastic housing components or halves to one another, screws are commonly utilized, with the screw shaft being configured to pass through one housing half, with the screw head held outside, and with the remainder of the threaded body of the screw passing into and being captured by blind bores, on the inside of the mating plastic housing half. The housing halves or components are thus held together with screws which have the threaded bodies of the screws pass through screw holes and then the tips of the threaded bodies of the screws held by internal screw receivers or bores for the screws. However, in manufacturing these toys, the screw-based attachment mechanism requires many steps, such as those relating to adding and securing the screws, and additional elements, particularly the screws. Often, these toys require a substantial number of screws to adequately secure the plastic components together and completely secure the housing halves together to form a toy hosuing. Thus, there is a time and production cost to manufacturing toys with screw-based attachment mechanisms for mating housing components. And, of course, if disassembly is required, for repair or replacement of internal pieces within the housing cavity, that, too, is time and labor intensive as the plastic housing components and their holding screws take time to remove and then reinsert, as required for reassembly, after the repair or replacement of internal components is accomplished. In light of these deficiencies associated with screw-based attachment mechanisms for plastic toy housing halves or components, there exists a need for a new and superior mechanism for affixing toy component housing halves together, preferably without the need for additional elements or screws, as well as a simple and quick mechanism or tool for disassembling the toy halves of a housing wherein the holding mechanism is not a set of metal screws. If a mechanism is developed, as set forth herein, which allows for ease of assembly (simply snapping the two housing halves together) and a quick, easy and simply method for disassembly, even requiring a new dedicated tool for use in that process, it would be highly advantageous to the manufacturer-resulting in cost and labor savings.
Towards that goal, the present invention relates to a new mechanism for securing the halves of a toy or housing to one another and a tool which can be used for disassembly, as required or desired. Snapping the two halves together to form an integrated housing with a central open cavity, wherein the halves of the housing are not secured by screws, is clearly highly beneficial to the manufacturer. The quickness and ease of use of a tool for quick and easy disassembly with respect to the plastic halves or components of the housing will result in significant cost and time savings. A superior end product is thus achieved.
In general, in one aspect, the invention relates to a new manner of assembling the plastic halves of a housing for a toy without the need for a multiple of screws holding the halves together. When assembled, the housing components or halves form a toy housing with an air-filled cavity, which often contain other components, e.g., hubs for turning gears, batteries, etc. And, the present invention discloses a new tool for use in quickly and easily disassembling a toy formed of mating housing components, preferably plastic halves which secured to one another. The tool generally includes a first arm formed with a handle and an opposed second arm with a handle, hinged to the first arm and handle, similar to that of a pair of pliers or a wrench but instead of the user using his/her hands to compress the handles to force the gripping end of the arms together, like a wrench, the mechanics of the device and a spring bias require that a pressing or compression of the handles results in the distal ends of the arms spreading apart. A first prong at the end of one of the arms opposes a second prong at the end of the other arm. When the handles are compressed together, against the force of the spring biasing the same toward one another, the distal extension of the arms and their prongs are separated. When disassembly of a toy housing is desired, the prongs of the tool are passed through small slots and into the cavity of the housing. Use of the tool on the housing halves of the toy will allow the holding mechanisms of the housing halves to be easily and quickly separated. Thus, unscrewing is not needed as there are no holding screws. The tool and the spreading of the prongs of the distal ends of the tool, causes opposed parallel and resilient (plastic) walls to separate and that allows the ends of a T-shaped member (held in aligned and opposed apertures of the walls) to be released from the walls. Thus, the two housing halves can be quickly and easily separated without the use of a screw driver as there are no screws holding the housing halves together. Planar pieces on the sides of the tool's hinged arms have opposed planar edges. These allow the tool to be easily abutted against the surface of the housing, with the prongs passing through holes in one of the housing's halves, between the opposed, parallel and resilient walls. Then, when the compression of the handles is manually accomplished, the housing halves are disengaged from one another. The arms of the tool, with their projecting prongs, as mentioned, are separated by a spring which biases the prongs and the arms towards one another. Yet, the arms are hinged to one another, about a mid point, so that squeezing together of the handles of the arms results in the arms and their distal prongs separating. A central hinge holds the arms and handles as a single tool, like a pair of pliers, and allows for compression of the handles to separate the prongs while the tendency of the spring, after the manual compression is removed, allows the arms and the prongs to close back towards one another. Compression of the handles will cause the distal prongs to separate. As they are placed within the housing, this causes the opposed, resilient, plastic walls to separate. This allows for a T shape, on the opposed housing half, to have its arms clear the holes of the opposed walls, so that the halves can be easily separated, thus providing the user with quick access to the cavity between the housing halves.
The tool is preferably provided with a mechanism limiting the amount of separation allowed by compression of the opposed handles. The spring between the arms tends to draw the handles back toward one another.
The plastic housing halves are manufactured such that one half will have, projecting from its inside surface, a plastic projection in the shape of a T with outwardly extending arms. The base of the T is secured to the inside surface of the half of the housing. The outwardly extending arms of the T are distal to the inside surface of the half to which the base of the T is attached. The arms of the T are received and held into an opposed set of parallel, resilient, preferably plastic, spaced walls, with opposed and aligned arm-receiving holes, with those walls projecting from the inside surface of the second or opposed half of the housing. The walls are somewhat resilient such that if they can be cammed or pushed outwardly by the action of the arms of the T shape being forced toward the inside surfacer of the opposed half. Then, when the arms are aligned with the apertures of the parallel, resilient walls, the arms snap into the apertures of the walls to capture the arms within the apertures of the walls. This, in effect, captures the first housing half (with the T shaped component) to the opposed, resilient, parallel walls, with aligned apertures of the second housing half, to integrate the two components into a single housing. When the tool is selectively used, the opposed walls are cammed outwardly, releasing the arms of the T shapes from the aligned apertures and, if separating force is applied to both halves of the housing, the two components can be easily separated. Thus, assembly and disassembly can be accomplished without the use of screws nor a screwdriver.
Implementations of the present invention may include one or more of the following features. The first arm of the tool with a distal prong and the second arm of the same tool, with a second distal prong, may be configured to move outward from one another when the first arm and the second arm are moved or squeezed together i.e., moved toward each other. This is, as mentioned, against a spring bias tending to push outwardly on handles of the arms and thus the distal prongs are normally biased towards one another. A central hinge point is provided in the tool, located between the ends of the prongs and the handles for the arms. A coil tension spring may be attached to and disposed between the handles of the first arm and the second arm. The spring tends to separate the handles and tends to move the distal ends toward one another. A portion of each of the first arm and the second arm may be provided with a rubber or plastic grip. The first prong or tip and the second prong or tip may include tapered portions or more preferably small round-shaped tips. The first prong and the second prong, with the tips projecting forwardly, may include substantially cylindrical tapered or small square end or tip portions having a dimension of their widths far smaller than the width of the remaining portions of the forwardly projecting first and second arms. The tips will extend through spaced apertures in the wall of one of the housing halves and the arms will lie between the opposed walls. When the handles of the tool are squeezed together, the tips of the prongs or arms will separate and bear against the resilient, flexible opposed walls. With the user pulling the two halves physically apart, the outwardly extending arms of the T shapes will be released from the apertures of the opposed apertures of the spaced walls, due to the resilience of the walls and the outward movement of the walls by the tool, to thereby release one half of the housing from the other.
In general, in another aspect, the invention features a system for assembling and disassembling a toy comprised of a pair of mating plastic shell housings. The toy generally is made of a first toy housing or shell component which is mated to and forms an enclosed shell or housing with a second toy housing or shell component. These components are generally formed of molded plastic. The first housing component has one part of a mating connector inside its shell with the other or second housing component having a mating component to that of the first housing component. Thus, together, there are one or more snap joints which hold the halves or shell components together into an integrated whole. One half will be provided with a set of two, inwardly (with respect to the outer wall of one half of the housing) substantially parallel, spaced but outwardly flexible or resilient side walls extending from an inside surface of the inner portion of the first toy component. Those resilient and preferably plastic walls are preferably formed when the housing is formed. The side walls extend toward the opposed inside surface of the opposed half shell of the housing. Each side wall includes an opening or aligned hole or aperture disposed therein and an aperture at a portion in which the side walls contact to the first toy component, with the apertures passing through the surface of the housing half. The two holes or openings of the side walls face one another. The side walls, on the inside of the first half shell of the housing extend from the inside wall of the first toy shell component towards the other shell's inside surface. Those walls, with their openings or holes, can be flexed or moved outwardly, due to their resilience, if a tool is inserted through holes in the first half of the shell, such that the tips of the tool force the walls to spread apart. The walls will also spread apart as the two shell halves are pressed together as the arms of the T shape of one shell bear against and outwardly flex on the parallel, resilient walls of the second shell.
The second half shell of the toy housing component has an inner surface or portion including one or more T-shapes extending from the inside surface of the first shell towards the other shell. These T-shapes are also integrated with the inside wall of the housing half and extend towards the opposed walls of the other shell. The head of the T-shape is aligned across the opposed walls of the shell half having the parallel walls such that the outward arms of the T-shapes are adapted to slide into and be held by the opposed openings in the opposed resilient walls. The outward edges of the arms of the T-shapes are angled so that a physical pushing of one shell towards the other has the edges of the T's arms slide against the parallel walls and cam outwardly the opposed walls of the shell half with the opposed walls until the arms, with the outside edges, “pop” and are held in the opposed openings or slots of the parallel, resilient, spaced side walls. When the two halves are aligned and the arms of the Ts slid into the openings of the opposed side walls of the opposed shell half, the housing halves are held together until desirably separated, by use of the tool disclosed herein. The opposed side walls are spread outwardly by the edges of the T shaped walls and then resiliently snap back, after the arms of the Ts, and the outside edges of the Ts, align with the openings of the opposed walls. Then, the walls snap back and the arms of the Ts are captured such that the edges of the arms are located within the holes of the opposed walls. Clearly, the outside edges of the arms of the T's are greater in width than the distance between two opposed, resilient side walls, when unflexed, and, yet, when the walls are bent outwardly, and the halves of the housing pulled apart, the distance between the apertures of the opposed, flexible, resilient walls exceeds the distance between the outside edges of the arms of the Ts, to release the same. This is the general manner of releasing (and securing) the two halves or half shells to one another to form an integrated toy housing. No screws nor extra pieces are required as the T shapes and their outwardly extending arms and the opposed and resilient walls with holes or apertures for capturing the arms of the Ts are formed as components of the plastic housing at the same time as the rest of the housing is formed. The components cooperate together to form connectors for the housing shells.
And, to disassemble or gain access to the inside of the housing, if needed, a simple new tool can be inserted having a pair of opposed arms, with protruding prongs and tips, through the outside holes of one of the housing halves, such that the prongs extend between the opposed walls and when the handles of the tool are pressed together to compress against the outward bias of the spring to thereby push the arms and prongs of the tool outwardly the arms of the T of one housing shell half can be simply pulled apart from the walls because the walls are separated, temporarily, by the tool. This, then, disengages the arms of the Ts from the capturing holes of the parallel walls and allows the halves of the housing to be easily separated. Again, the assembly and disassembly of the housing is done without any screws and this saves both time and money.
Implementations of the invention may include one or more of the following features. A coil tension spring may be attached to and disposed between the first arm and the second arm of the tool. That, in well-known mechanical fashion, will bias the arms and the prongs (and tips) of the tool, inwardly toward one another. That is because the arms and prongs of the tool are connected to the opposite handles, in much the manner of a pliers or wrench, with a central hinge and a biasing spring. A portion or handle of each of the first arm and the second arm of the tool may be provided with a rubber or plastic grip. The first prong and the second prong of the tool, at the ends of the arms, may include tapered end or tip portions. The first prong and the second prong of the tool may include substantially cylindrical end portions having a width much smaller than a width of the remaining portions of the first prong and the second prong. The arms and handles are hinged to one another by a screw member passing through the center section, like the arms and handles of a wrench or pair of pliers, and are hinged about a post. In a preferred embodiment of the invention, the arms of the tool are maintained at a spaced initial distance apart by a post or screw extending between the opposed arms. Thus, the arms cannot contact one another but can further be spread by the compression of the handles of the opposed arms. And, in another embodiment, the arms and prongs of the tool are surrounded by one or more planar members which ease location of the arms and prongs into the holes of the housing, with the prongs bearing against the surface of the parallel walls, such that the planar member(s) ease alignment of the tool against the flat outer section of the housing.
In general, in another aspect, the invention features a method of disassembling a toy, including providing a toy comprised of mating and opposed housing half shells, along with a tool, where the toy includes a first toy shell component having a cavity-like inner portion including one or more snap joints composed of two substantially parallel and resilient side walls extending from a surface of the inner portion of the first toy shell component, with the opposite shell component, also cavity like, having a T-shaped member, with outwardly extending arms, extending across the parallel walls of the opposed shell half. The walls of the shell half are capable of accepting the arms, when the parallel walls are allowed to be bent away from perpendicular to the inside surface of the housing, such that the arms of the T shapes slide into the apertures of the T walls and then capture the arms when the walls are allowed to snap back to their original, position i.e., perpendicular to the inside surface of the shell housing half. The prongs of the tool can reach through adjacent slots, reach between the opposed vertical walls of the shell and when the tool's handles compressed, that action causes the walls to gently and resiliently be pushed apart to release the edges and arms of the T-shapes from being captured by the holes of the opposed, parallel walls. This release allows the two shell halves to be manually separated. If the housing halves are desired to be reassembled, the halves are aligned, with arms of the T-shapes extending across the opposed vertical, parallel walls and then the two halves can be pushed together. That action will allow the edges of the T-shape to cam in between the side walls until they first push outwardly, the arms sliding down into the apertures of the side walls, and then snap back to capture the arms of the Tshapes within the holes of the walls. This will result in a firm, unitary housing, made of a pair of opposed housing halves. Assembly of the two halves does not require any tool and no screws are needed.
Implementations of the invention may include one or more of the following features. A coil tension spring may be attached to and disposed between the first arm and the second arm of the tool. A portion of each of the first arm and the second arm of the tool may be provided with a rubber grip or a plastic grip. The first prong and the second prong of the tool, at the ends of the arms, may include tapered or tip portions. The first prong and the second prong of the tool may include substantially cylindrical end portions (or rectangular in cross section profiles) having a width smaller than a width of the remaining portions of the first prong and the second prong. Mechanical devices can be provided to the tool to prevent over separation of the arms and also prevent the arms from coming completely together, i.e., the arms can be maintained at a predetermined separation.
A first half shell of the housing will have a pair of opposed, vertical parallel walls. The bottom of that shell half will be provided with a set of holes which allow for the prongs of the tool to pass therethrough, when selective disengagement of the two halves is desired. The opposed and parallel, outwardly resilient walls extend toward the inside cavity of the shell/housing. The walls are provided with opposed and aligned holes or apertures. The walls are resilient and can be flexed outwardly by the action of sliding the two halves of the housing toward one another for assembly or by use of the tool, for selective disassembly. The opposed shell of the housing is provided with a T-shaped extension, extending across the opposed walls of the first shell half. The T-shape has a pair of opposed, outwardly extending arms with edges. The edges extend or taper inwardly, from the base of the T-shape toward its top. The T-shape extends generally across the vertical walls of the opposing shell half and the arms are separated a determined distance so that they will be captured by the opposed holes of the walls. The two housings preferably are connected together by simply pressing the two mating halves together, without the need for any tools nor screws. When the two halves are pressed together, the vertical walls of the first shell half will flex outwardly and glide over the edges of the arms of the T-shape until the arms of the T-shape pop into the holes of the walls. Since the walls are outwardly resilient, they will gently and easily glide over the edges of the arms of the T-shape. Once captured, the arms within the holes of the walls, will be maintained until and unless the tool is used to force the walls outwardly so that the arms of the T-shape are released. The width of the arms of the T-shape exceeds that of the distance between the opposed holes and, yet, the arms can be released when the walls are spread outwardly by the tool. This will allow the T-shape to be separated from the spaced and temporarily separated walls, allowing the two housing shells to be separated. One or more of these connections between the two shell halves should be employed to hold the housing together. The number of such connections will be primarily determined by the size of the device. As mentioned, the T-shapes extend from one housing shell component or half with the opposed and parallel walls extending from the other housing shell. The T-shapes and the opposed, resilient walls (the latter being resilient to flex outwardly and when stress is removed to snap back into a position wherein the walls are substantially perpendicular to the inside surface of the shell half) cooperate to hold the shell halves together. The tool can be used to separate the halves, if desired. However, the tool is not required when initial assembly is performed as merely pressing the T-shape between the walls, with the edges of the T-shape camming outwardly the walls, will result in the T-shape and its arms gliding along the surfaces of the spaced walls and then the edges of the T-shapes are captured between the opposed holes of the walls.
The tool 10 is best shown in
As can be appreciated by one of skill in the art, the left handle 101 continues on as left projecting piece 112 and the right handle 102 continues as the right projecting piece 111. Alternatively, the forwardly projecting arms and their prongs or tips can be mechanically connected in other ways but, in any event, the squeezing of the handles is meant to result in a small further separation of the prongs or tips. A spring 103 is provided between the two handles to bias the handles of the tool apart from one another. This keeps the prongs or tips near to one another. The spring 103 biases the projecting pieces 111 and 112, along with their prongs or tips 151 and 153 so the tool, when not squeezed, has the prongs or tips close to one another. Squeezing the handles together, against the outward bias of the spring 103, will cause the handles to near one another and in turn causes the tips 151 and 153, to further separate. However, as can be seen in
Turning back to the toy housing, the top half or shell 12 is snapped to the bottom half or shell 14 by one or more interior snap connectors. These avoid the use of screws to connect together the halves of the housing. Simple alignment of the outside rims of the two halves and pressing of the halves together will cause the opposed and engaging snap connector pieces to mate and secure the housing into a single toy housing with an interior cavity. The inside surface 20 of the top half or shell 12 is provided with one component of the snap connectors while the inside surface 22 of the bottom shell or half 14 is provided with the other and mating component of the snap connectors 16. Each snap connector is comprised of a T shaped plastic piece extending into the cavity (with the arms or larger part of the T being disposed away from the inside surface of the housing half) while the inside surface of the bottom half (the components of the snap connectors can, of course, be switched) is provided with a pair of opposed parallel walls 26 and 27 which extend into the cavity and extend toward the inside surface 20 of the top shell. When connected together the outwardly extending arms of the T shaped component is captured and held within the opposed and aligned holes or apertures 28 of the opposed parallel and resilient walls 26 and 27. The distance between the opposed walls 26, 27 (when the walls are not cammed outwardly) is less than the distance between the edges 32 and 33 of the top or arms of the T shaped component.
In practice and use, to mate the two halves and form an integrated cavity-containing housing, the two halves of the housing are merely aligned and pushed toward one another. The outward edges of the top or arms of the T shaped component, which slant downwardly and outwardly from bottom of arms of the T to the top of the T, cam or push the opposed parallel walls of the other member of the snap connector outwardly (See
To selectively disassemble the two halves, if required, a tool is provided. The tips of the tool are first inserted into the housing through aligned apertures in that housing half's surface. Those apertures are aligned to be just inside the space defined by the parallel walls. Then, a user preferably operates tool 10 by placing first arm 101 and second arm 102 within the user's hand and applying pressure to, i.e., squeezing together, first arm 101 and second arm 102. First arm 101 and second arm 102 may optionally be configured with a grip, such as a rubber or plastic grip, on a portion thereof. A coil tension spring 103 may be attached to and disposed between first arm 101 and second arm 102 to provide a release of the splitting apart tension of the tool, a consequence of the squeezing of the handles towards one another.
Tool 10 includes a first prong 111 and a second prong 112; each provided with a distal tip member. First prong 111 and second prong 112 are connected to first projecting arm 101 and second projecting arm 102 via a bottom screw 124. First prong 111 and second prong 112 may taper down toward their respective ends, preferably the tip ends are round or square in cross section, at a portion distally located from the connection between prongs 111 and 112 and arms 101 and 102. First prong 111 and second prong 112 may be configured with an additional cylindrical or substantially cylindrical point at their respective ends, preferably the ends distally located from the connection between prongs 111 and 112 and arms 101 and 102.
Tool 10 may also include a housing engaging, planar stopper element 120. Stopper 120 may have a first stopper side 121 and a second stopper side 122, disposed on opposite sides of the assemblage of prongs 111 and 112 and arms 101 and 102. The tips project past the front edge of the stopper element 120. First stopper side 121 and second stopper side 122 are affixed to one another via a top screw 123 and the separate bottom screw 124. Top screw 123 passes between first prong 111 and second prong 112 in affixing first stopper side 121 and second stopper side 122 together. Therefore, as a result of the placement of top screw 123, first prong 111 and second prong 112 do not fully close to contact each other but rest against the outside diameter or screw threads of the top screw 123 when tool 10 is inactive. This prevents the prongs and tips from coming into contact with one another. Bottom screw 124 passes between prongs 111 and 112 and arms 101 and 102 in affixing first stopper side 121 and second stopper side 122 together. The front and preferable U-shaped edges of the stopper 120 prevents tool 10, specifically prongs 111 and 112, from fully penetrating certain objects, and rests on an outer surface, the true bottom of the bottom half or shell 14, when the tool is deployed to separate the halves of the housing. The U shaped front edges of the stopper rests against the housing bottom surface when prongs 111 and 112 and their tips are inserted into toy housing 20 for disassembly.
The bottom half or shell 14 is preferably the shell half provided with the inwardly projecting (i.e., towards the center of the cavity), originally parallel, yet outwardly bendable, resilient walls. These have their “free” ends extending toward the inside of the housing, and project toward the inside surface of the top half or shell 12. Those walls are provided, near their distal ends, with a pair of opposed, aligned apertures. It is those apertures that capture the sides or edges of the arms of the T shaped extension. Those T shaped extensions (See
The tool however can be selectively inserted into holes in the bottom housing. These holes are located just on the inside i.e., between the parallel walls. The holes accept the tips of the projecting arms and the surface of the stopper will abut the outside surface of the bottom half or shell of the housing. With the tips inserted into the cavity of the housing, the forwardly projecting arms will glide on the inside of the opposed walls. Then, with the tips and part of the arms inserted between the walls, the user can gently squeeze the handles of the tool. That will cause the tips and the arms to separate. They are on the inside, i.e. between the parallel walls of the bottom shell. Squeezing of the handles separates the tips. Separating the tips causes the resilient walls, extending from the inside surface of the bottom shell, to be pushed or cammed outwardly. As those walls separate outwardly and along with the pulling of one housing half away from the other housing half, the apertures of the walls clear beyond the outward extension of the arms of the T shaped component (both arms of the T). These, it will be recalled, project from the inside of the housing and are distal from the inside surface of the top half or shell. Then, at the same time as maintaining the walls separated (so that they are no longer parallel within the cavity) the mechanic can continue to pull and thus easily separate the top shell from the bottom shell for easy access to the cavity. A pair of slots or apertures are located through the bottom shell or half 14, aligned with the inside surfaces of the opposed walls and it is through those apertures or slots that the tips of the tool and part of the tool's arms project when the tool is placed into engagement (stopper against the surface of the housing) with the toy housing's bottom surface. The tips and a portion of the projecting arms separate the parallel walls so that the edges of the arms of the T shaped component “clear” the apertures of the resilient and outwardly spread side walls.
It should be easily appreciated and understood that the T shaped snap prongs are spaced about the top shell of the housing to coordinate with the opposed walls of the bottom shell. The snap prongs extend across the parallel walls so that, when assembled, the arms of the snap prongs will snap into the aligned and opposed holes of the parallel walls.

To use the tool for disassembly, prongs 111 and 112 of tool 10 may be inserted into slits or openings 213 and 214 of the bottom shell. Those openings pass completely through the bottom shell's wall's thickness. Upon squeezing arms 101 and 102 of tool 10, prongs 111 and 112 move outward from one another. Since prongs 111 and 112 have already been inserted into slits 213 and 214, such outward movement of prongs 111 and 112 causes first side wall 211 and second side wall 212 to bend away from each other. This bending releases the snap prong 220, particularly the wider (outward extension of the arms of the T) portion of snap prong 220, from openings 215 and 216. This bending and release is illustrated in
