DETAILED DESCRIPTION

A portion of an exemplary frame pool 100 is shown in FIGS. 1 and 2. The illustrative portion of the frame pool 100 includes two adjacent horizontal frame members 6 (e.g., horizontal pipes) that cooperate to form an upper rim of the frame pool 100 and a vertical frame member 7 (e.g., vertical pipe) that extends downward from the horizontal frame members 6 to support the frame pool 100 on the ground. Although not shown in FIGS. 1 and 2, similar frame members 6 and 7 may be provided around the remaining perimeter of the frame pool 100. The frame pool 100 may vary in size and shape. For example, the frame pool 100 may be rectangular, circular, elliptical, or other suitable shapes.

Referring still to FIGS. 1 and 2, a T-shaped joint 10 may be used to removably couple the two adjacent horizontal frame members 6 to the adjacent vertical frame member 7. Although a single T-shaped joint 10 is shown in FIGS. 1 and 2, similar T-shaped joints 10 may be provided around the remaining perimeter of the frame pool 100. Each T-shaped joint 10 illustratively includes two horizontal joint portions 1 configured to couple to the horizontal frame members 6 and a vertical joint portion 2 configured to couple to the vertical frame member 7. To form the T-shape, the vertical joint portion 2 is centered between and perpendicular to the two horizontal joint portions 1. The orientation of the horizontal joint portions 1 determines the orientation of the adjacent horizontal frame members 6. In the illustrated embodiment of FIG. 1, for example, the horizontal joint portions 1 define an obtuse angle α therebetween, so the horizontal frame members 6 define the same angle α therebetween. In another embodiment, the horizontal joint portions 1 may be collinear with each other, so the horizontal frame members 6 would also be collinear with each other. In another embodiment, the horizontal joint portions 1 may be perpendicular to each other, so the horizontal frame members 6 would also be perpendicular to each other, such as along a corner of a rectangular frame pool 100.

Some or all components of the frame assembly, including the horizontal frame members 6, the vertical frame members 7, and/or the T-shaped joints 10, may be constructed of a polymer, specifically plastic, such as by injection molding. Compared to metallic components, the plastic components may be smooth and elastic to facilitate assembly and disassembly of the frame assembly. Also, the plastic components may be more resistant to galling and corrosion to promote extended use. With respect to the T-shaped joint 10, in particular, the horizontal joint portions 1 and the vertical joint portion 2 may be integrally formed as a single piece of plastic. Alternatively, the horizontal joint portions 1 and the vertical joint portion 2 may be formed as multiple pieces of plastic and then fixedly coupled (e.g., adhered, welded) together. The upper end of the T-shaped joint 10 may include a raised rim 22 (FIG. 3) to give the appearance that the vertical joint portion 2 wraps around the horizontal joint portions 1.

The illustrative frame pool 100 of FIG. 1 also includes a pool liner 8 supported by the frame members 6 and 7 to form an interior water cavity for swimming and/or bathing. The pool liner 8 may be wrapped and secured around the horizontal frame member 6 to form a loop or fold 81. The fold 81 of the pool liner 8 may also define a gap or hole 82 to expose the T-shaped joint 10, as described further below.

The illustrative T-shaped joint 10 is described in more detail with reference to FIGS. 3 and 4.

The horizontal joint portions 1 of the illustrative T-shaped joint 10 are configured to couple with the adjacent horizontal frame members 6 (FIG. 2). The horizontal joint portions 1 may be configured to fit within the adjacent horizontal frame members 6 in a sleeved manner. Thus, the external cross-section of the horizontal joint portions 1 may match the internal cross-section of the horizontal frame members 6. In the illustrated embodiment of FIG. 3, the external cross-section of the horizontal joint portions 1 is generally triangular with rounded edges to resist rotation between the horizontal joint portions 1 and the horizontal frame members 6. It is also within the scope of the present disclosure for the external cross-section to be circular, rectangular, elliptical, or another suitable shape to match the internal cross-section of the horizontal frame members 6.

Each horizontal joint portion 1 of the T-shaped joint 10 includes a coupling assembly 3 for removable attachment to the adjacent horizontal frame member 6 (FIG. 2). As shown in FIGS. 3 and 4, each coupling assembly 3 includes a base 31 received in the horizontal joint portion 1, a helical spring 32 held in place by the base 31, and a pin 33 extending radially outward (e.g., downward) through a hole 35 in the horizontal joint portion 1. Each horizontal joint portion 1 may include an internal horizontal reinforcing rib 11 and/or an internal horizontal support member 5 to help support base 31 within the T-shaped joint 10. In an assembled or locked state, spring 32 may bias pin 33 radially outward through hole 35 to engage a corresponding recess or hole (not shown) of the horizontal frame member 6 (FIG. 2). In a disassembled or unlocked state, a user may press pin 33 radially inward to compress spring 32 and disengage the horizontal frame member 6 (FIG. 2).

The vertical joint portion 2 of the illustrative T-shaped joint 10 is configured to couple with the adjacent vertical frame member 7 (FIG. 2). The vertical joint portion 2 may be configured to fit within the adjacent vertical frame member 7 in a sleeved manner. Thus, the external cross-section of the vertical joint portion 2 may match the internal cross-section of the vertical frame member 7. In the illustrated embodiment of FIG. 3, the external cross-section of the vertical joint portion 2 is generally triangular with rounded edges to resist rotation between the vertical joint portion 2 and the vertical frame member 7. It is also within the scope of the present disclosure for the external cross-section to be circular, rectangular, elliptical, or another suitable shape to match the internal cross-section of the vertical frame member 7.

The vertical joint portion 2 of the T-shaped joint 10 includes a coupling assembly 4 for removable attachment to the adjacent vertical frame member 7 (FIG. 2). As shown in FIGS. 3 and 4, each coupling assembly 4 includes a base 41 received in the vertical joint portion 2, a helical spring 42 held in place by the base 41, and a pin 43 extending radially outward (e.g., rearward) through a hole 45 in the vertical joint portion 2. The vertical joint portion 2 may include one or more internal vertical reinforcing ribs 21 to help support base 41 within the T-shaped joint 10, such as by compressing fingers 46 of base 41 together within the T-shaped joint 10. In an assembled or locked state, spring 42 may bias pin 43 radially outward through hole 45 to engage a corresponding recess or hole 71 of the vertical frame member 7 (FIG. 2). In a disassembled or unlocked state, a user may press pin 43 radially inward to compress spring 42 and disengage the hole 71 of the vertical frame member 7 (FIG. 2).

According to an exemplary embodiment of the present disclosure, and as shown in FIG. 4, the size of the T-shaped joint 10 may be minimized such that the size of the corresponding hole 82 in the pool liner 8 (shown in phantom) may also be minimized. The small hole 82 in the pool liner 8 may improve the appearance and water containment of the frame pool 100 (FIG. 1) while still leaving the coupling assemblies 3 and 4, specifically the pins 33 and 43 of the coupling assemblies 3 and 4, accessible for subsequent disassembly.

The width of the T-shaped joint 10 may be minimized such that the width of the corresponding hole 82 in the pool liner 8 may also be minimized. For example, the total width W_J1 of the T-shaped joint 10 may be about 5 inches to about 7 inches, specifically about 5¾ inches, the width W_J2 between the pins 33 of the coupling assemblies 3 may be about 3 inches to about 5 inches, specifically about 3 13/16 inches, and the width W_J3 of the vertical joint portion 2 may be about 1 inches to about 3 inches, specifically about 2⅜ inches. In the illustrated embodiment of FIG. 4, the width W_L of the hole 82 in the pool liner 8 is greater than both the width W_J3 of the vertical joint portion 2 and the width W_J2 between the pins 33 to expose the pins 33 of the coupling assemblies 3 for subsequent disassembly while being less than the total width W_J1 of the T-shaped joint 10. For example, the width W_L of the hole 82 in the pool liner 8 is about 3 inches to about 7 inches, specifically about 4½ inches.

To help minimize the size of the T-shaped joint 10, the pins 33 of the coupling assemblies 3 may be positioned close to the vertical joint portion 2. Due to this close positioning, the width W_J3 of the vertical joint portion 2 may account for a majority of the width W_J2 between the pins 33 of the coupling assemblies 3. For example, the width W_J3 of the vertical joint portion 2 may account for 50%, 60%, 70%, 80%, or more of the width W_J2 between the pins 33 of the coupling assemblies 3. In the illustrated embodiment of FIG. 4, in particular, the width W_J3 of the vertical joint portion 2 accounts for about 70% of the width W_J2 between the pins 33 of the coupling assemblies 3. The width W_J3 of the vertical joint portion 2 may also account for a significant portion of the total width W_J1 of the T-shaped joint 10. For example, the width W_J3 of the vertical joint portion 2 may account for 40%, 50%, 60%, 70%, or more of the total width W_J1 of the T-shaped joint 10. In the illustrated embodiment of FIG. 4, in particular, the width W_J3 of the vertical joint portion 2 accounts for about 50% of the of the total width W_J1 of the T-shaped joint 10.

Additionally, the height of the T-shaped joint 10 may be minimized such that the height of the corresponding hole 82 in the pool liner 8 may be minimized. For example, the total height H_J of the T-shaped joint 10 may be about 3 inches to about 5 inches, specifically about 3⅞ inches. Because the pin 43 of the coupling assembly 4 may be accessible in front of the pool liner 8 and behind the T-shaped joint 10, the hole 82 in the pool liner 8 need not extend downward beneath the pin 43. Thus, in the illustrated embodiment of FIG. 4, the height H_L of the hole 82 in the pool liner 8 is less than the total height H_J of the T-shaped joint 10 while still allowing access to the pin 33 of the coupling assembly 3 and the pin 43 of the coupling assembly 4 for subsequent disassembly.

While this invention has been described as having exemplary designs, the present invention can be further modified within the spirit and scope of this disclosure. This application is therefore intended to cover any variations, uses, or adaptations of the invention using its general principles. Further, this application is intended to cover such departures from the present disclosure as come within known or customary practice in the art to which this invention pertains and which fall within the limits of the appended claims.
