Description
A DEVICE FOR LIFTING A SPA COVER
TECHNICAL FIELD
(oooy The present invention relates to spa cover lifting devices.
BACKGROUND OF THE INVENTION
(00021 Typically, a heated spa has an insulated spa cover to retain the heat of the spa water as well as to protect the water from debris when the spa is not in use. A
number of different spa cover configurations exist to conform to various spa constructions. Spa covers range from soft, single sheets of vinyl or other materials, to hard covers formed of thick, insulated foam padding enclosed by a protective, impervious casing. Often times, hard insulated spa covers are preferred as they significantly reduce heat loss which reduces the overall cost of operating a spa.
(00031 A conventional hard spa cover is commonly foldable formed of two halves joined along a central hinge. Such spa covers are often removed by first folding one cover half over onto the other cover half, and then lifting both cover halves from the spa.
A spa cover lifting device is employed to facilitate the removal and replacement of the spa cover by way of a pivoting lifting frame that engages the spa cover at its center hinge and transpouts the folded cover to a convenient vertical storage position or returns the folded cover from the storage position to on top of the spa.
(00041 Many different designs of spa cover lifting devices exist, however, most take up a lot of space and are cumbersome to install and use. Another problem frequently encountered with existing lifting devices is the lack of adaptability to various shapes, sizes and types of spas. For example, lifting devices ,including mounting brackets adapted to be mounted to the side walls of a spa cannot easily be secured to a spa having a non-uniform external surface. This is the case for spas that are being conshmcted from artificial stones, as it is desirable for the artificial stones to have a natLUal looking appearance. Even snore, the artificial stones being used are made of a light weight relatively. soft material that is unable to bare the load of a bracket mounted thereon.
Furthem~ore, few spa cover lifting devices are designed to operate on non-rectangular shaped spas, and those that can accommodate unconventional spa designs tend to be much higher in price.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
(ooi71 Figs. 1 and 2 illustrate a preferred embodiment of a spa assembly generally designated by reference numeral 1. The spa assembly 1 generally comprises a spa cover lifting device 10, a spa 12 and a spa cover 14. The spa cover lifting device t 0 depicted in this exemplary embodiment incorporates featltres of the present invention.
The lifting device 10 is shown mounted to the spa 12 with a foldable spa cover 14. The teen "spa" is used to generally describe a hot tub or bath facility with a whirlpool that is customarily used outside. The spa 12 has a plurality of opposite sides, and more specifically, four side walls 16 extending upwardly from an under surface 17 to define a generally rectangular structure with a top 18. It should be understood that the spa 12 can be of various shapes and sizes without departing in breath and scope from the present invention.
100181 The spa cover 14 shown in its folded position in Figs. 1 and 2 is designed to complement the spa shape and sit on the top 18 of the spa 12 to insulate and protect the spa water. The spa cover 14 is commonly provided in two parts 20, preferably in halves, that are connected along a folding joint 22. The folding joint 22 is frequently formed by a flexible material. More particularly, the flexible casing material encapsulating the insulation within the spa cover 14 is sewn to form a seam between the two encapsulated foam parts 20.
~ools~ Referring now to Fig. 3, a preferred embodiment of the lifting device 10 is illustrated. The lifting device 10 generally comprises a pivoting assembly 24 operatively attached at respective ends thereof 26 to a pair of brackets 28 for pivotal movement. The pivoting assembly 24 is pivotally movable from a first position with the spa cover 14 seated on the top 18 of the spa 12, to a second position with the spa cover folded over at the folding joint 22 and raised adjacent the spa. Preferably, the pivoting assembly 24 in the second position supports the spa cover 14 such that it is suspended about the pivoting assembly 24 folded at the folding joint 22 thereof. The pivoting assembly 24 is designed to carry the spa cover 14 from a resting position on the top 18 of the spa 12 to a raised position adjacent the spa as shown in Figs. 1 and 2. The raised position is preferably in a substantially vertical orientation adjacent one of the side walls 16 of the spa 12 to minimize space requirements.
100201 It should be noted at this point that the pivoting assembly 24 depicted in Figs. 1 to 3 is merely one possible configuration thereof. Generally, the pivoting assembly 24 comprises opposed side members 30 joined by a coupler 32 in a U-shaped formation. The side members 30 are each pivotally mounted to one of the brackets 28 at their respective ends 26.
100211 More specifically, the pivoting assembly 24 is preferably provided in multiple segments to form a kit so as to minimize the storage space required and thereby facilitate transportation of the lifting device 10. The pivoting assembly 24 kit includes the side members 30 provided as three separate segments: a pair of upper L-shaped corners 34 joined to a pair of lower L-shaped corners 36 respectively by vertical couplers 38.
The coupler 32 is adapted to be horizontally oriented, with respect to a flat surface on which the spa 12 is seated, and to join the pair of upper L-shaped corners 34.
As clearly shown in Fig. 3, the lower L-shaped corners 36 are positioned in a plane parallel to opposed side walls 16 of the spa 12 about which the brackets 28 are mounted, and perpendicular to the plane in which the remaining segments of the pivoting assembly 24 are positioned. Furthermore, the lower L-shaped corners 36 rest on the surface on which the spa 12 is rested by means of respective adjustable stoppers 37.
(00221 Notably, the side members 30 and coupler 32 are tubular to favor a light weight pivoting assembly 24. Thus, the open ends 26 of the pivoting assembly 24, and more specifically of the lower L-shaped corners 36, are capped to prevent the entrance of debris or water therein and to yield a more aesthetically pleasing design.
Caps 39 are preferably press-fit into the open ends 26.
(00231 Therefore, the distance between the side members 30 can be adjusted in accordance with the width of the spa cover 14 to permit the pivoting assembly 24 to connect with the brackets 28 located in spaced relation at opposed sides of the spa 12.
During installation, the pivoting assembly 24 is adjusted such that when in the first position the horizontal coupler 32 is aligned with the folding joint 20 of the spa cover 14, adjacent thereto. Thus, positioning the pivoting assembly 24 as such enables the spa cover 14 to be folded over the coupler 32 for removal thereof, and to be suspended over the coupler 32 for upright storage adjacent one side of the spa 12 when the pivoting assembly 24 is in the second position. Furthermore, the configuration of the pivoting assembly 24 having one end of the lower L-shaped corners 36 pivotally attached to the brackets 28 respectively, as best shown in Fig. 3, advantageously allows for the spa cover 14 to be minimally elevated during removal thereof. Thus, the design of the side members 30 allows for the spa cover 14 to be suspended proximal to the spa 12 and conveniently at a lower vertical position than would be the case if a straight side member were employed.
(00241 The multiple segments are adjusted and secured together during installation via fixation means. Particularly, the upper and lower L-shaped corners 34 and 36 have a series of holes 40 for receiving self tapping screws 42 that fixedly connect the horizontal and vertical couplers 32 and 38 respectively thereto. The couplers 32 and 38 are preferably slightly smaller in diameter than the corners 34 and 36 and are thus installed by telescopic insertion partly into the latter segments. Naturally, other fixation means commonly know in the art can also be used.
(00251 At this point it should be stated that the pivoting assembly 24 can also be provided in another embodiment without the coupler 32. Thus, the upper L-shaped corners 34 can engage the spa cover 14 at the folding joint 22 allowing the lifting device to function in a similar fashion as above-described. Preferably, in this alternative embodiment the folding joint 22 is provided with a sleeve (not shown) for receiving the free ends of the upper L-shaped corners 34.
(oo2s1 Now referring concurrently to Figs. 1 through 5, the brackets 28 of the spa cover lifting device 10 can be seen both installed on the spa 12 and separately therefrom.
In the preferred embodiment, the pair of brackets 28 are configured to be mounted on opposite sides of the spa 12 in one of a first and a second position. The pair of brackets 28 in the first position are horizontally oriented adapted to be inserted under the spa 12.
The pair of brackets 28 in the second position are vertically oriented adapted to be mounted to opposite side walls 16 of the spa 12. Preferably, the brackets 28 are vertically mounted to the base of the opposite side walls 16, proximal to the surface on which the spa is rested to keep the vertical position of the spa cover 14 when suspended to a minimum.
(00271 As illustrated in Figs. 1 and 2, the brackets 28 are configured to be mounted beneath the under surface 17 the spa 12 at opposite sides thereof, such that the brackets 28 are maintained in position by the weight of the spa 12 once the spa is filled with water. It should be understood that during installation, the brackets 28 should be inserted under the spa 12 when it is empty.
(oo2sl It is preferable that the brackets 28 are substantially identical and positioned in mirror relation to one another with respect to the spa 12;
therefore, only one bracket 28 will be described in detail with the understanding that the same description applies to the other.
(oo2s1 Referring concurrently to Figs. 4 and 5, a preferred embodiment of a bracket 28 for use in a spa cover lifting device 10 is illustrated. The bracket 28 comprises a substantially flat, elongated member 44 with respective ends 46, 48. The elongated member 44 defines a top and a bottom surface 50 and 52 respectively. The bracket 28 further comprises a suppouting member 54 projecting from the top surface 50 at one end 48 of the elongated member 44. The supporting member 54 has first and second attachment sites 56 and 58 respectively adapted to be pivotally engaged with one of the side members 30 of the pivoting assembly 24 of the spa cover lifting device 10. The first attachment site 56 defines a first pivot axis 60 substantially parallel to a plane defined by the elongated member 44 and proximal to the top surface 50 thereof. The second attachment site 58 defines a second pivot axis 62 substantially perpendicular to the plane defined by the elongated member 44.
(00301 The bracket 28 is selectively engageable with the spa 12 in one of a first and second position as depicted in Figs. 4 and 5 respectively. The bracket 28 in the first position is adapted to be inserted under the spa 12 with the spa 12 seated on the top surface 50 of the elongated member 44 and the supporting member 54 adjacent a side wall 16 of the spa 12. The bracket 28 in the second position is adapted to be mounted to a side wall 16 of the spa 12 with the supporting member 54 projecting away from the side wall 16. In this exemplary embodiment the bracket 28 selectively engaged in the first position is horizontally oriented and selectively engaged in the second position is vertically oriented.
(oo3i1 Still referring concurrently to Figs. 4 and 5, it can be seen that the supporting member 54 has a prismatic shape. Preferably, it is provided as an inverted U
construction projecting from the top surface 50 of the elongated member 44.
The supporting member 44 includes a first, a second and a third section 64, 66 and respectively, preferably intersecting at substantially right angles to form an inverted U
constmction. More specifically, the first section 64 projects vertically from one end 48 of the elongated member 44. The second section 66 projects horizontally from the first section 64 in parallel relation to the elongated member 44. The third section 68 extends substantially vertically from the second section 66 towards the top surface 50 in parallel relation to the first section 64. The third section 68 has a horizontal extension 70 that rests flush on the top surface 50 of the elongated member 44 to reinforce the supporting member 54. The extension 70 is fixed to the top surface 50 by way of adhesive or other fixation means commonly known in the art. Preferably, the supporting member 54 is an integral extension from the elongated member 44 such that the bracket 28 is substantially fabricated from a single piece of material bent into shape. The bracket design of the preferred embodiment is simple and compact. Thus, the bracket 28 can be inexpensively manufactured.
(00327 Fuuthermore, the first and second attachment sites 56 and 58 are disposed on the first and second sections 64 and 66 respectively. The first and second attachment sites 56 and 58 are selectively engageable with one of the side members 30 of the pivoting assembly 24 by way of threaded fasteners 72. It should be understood that only one of the first and second attachment sites 56 and 58 is selectively engaged during installation of the spa cover lifting device 10, the selection between the two depending on the desired bracket 28 position. When the bracket 28 is in the first position, the first attachment site 56 is selectively engaged and when the bracket 28 is in the second position, the second attachment site 58 is selectively engaged.
(00331 More specifically, the first and second attachment sites 56 and 58 define respective apertures 74 and 76 for selectively receiving a pin 78 in alignment with the selected one of the first and second pivoting axis 60 and 62 respectively. The threaded fasteners 72 as seen in Figs. 4 and 5 include threaded pin 78 that is adapted for insertion through a pair of opposing circumferential holes 80 defined at the end 26 of the lower L-shaped corner 36 and through the selected aperture 74 or 76. The axis detined through the holes 80 is perpendicular to the axial direction of the tubular corner 36.
Also included is a pair of spacers 82 with central holes 84 and semi-circular receiving portions 86 that is adapted to mate with the tubular corner 36 on opposite side thereof in alignment with holes 80. A pair of washers 88 and a nut 90 are also included Such that one of the washers 88 is positioned between the head of the pin 78 and one of the spacers and the other is positioned between the nut 90 and the inside surface of the second section 66 of the supporting member 54. Finally, a rounded pin head cap 92 is preferably provided to create a smooth surface by hiding the angular edges of the pin 78 head. The pin head cap 92 also helps create an aesthetically pleasing design.
[00341 Still referring concurrently to Figs. 4 and 5, it can be seen that the elongated member 44 of the bracket 28 is provided with a plurality of aperhires 94 for receiving fasteners (not shown) therethrough such that the bracket 28 can be mounted to a side wall 16 of the spa 12. Preferably, a gasket 96 configured to complement the shape of the elongated member 44 of the bracket 28 is provided for mating flush with the bottom surface 52 thereof. The gasket 96 is provided with a plurality of apertures 98 for alignment with apertures 94 of the elongated member 44. Thus, the gasket 96 is adapted to be mounted between the side wall 16 of the spa 12 and the bottom surface 52 of the bracket 28 such that the fasteners are inserted through the aligned apertures 94 and 98.
The gasket 96 acts as a protective layer for preserving the side wall 16 surface of the spa 12 and as a seal for keeping the fasteners (not shown) dry to prevent rust formation.
(00351 The gasket 96 can also be used when the bracket 28 is selectively engaged beneath the under surface 17 of the spa 12. Notably, the bracket 28 and gasket 96 do not need to be fastened via fasteners in this position as the weight of the spa 12 prevents movement thereof; therefore, the gasket 96 acts as a protective layer.
Preferably, the gasket 96 is made from an elastomeric material to ensure sealing capabilities.
The material selected is also preferably pliable.
~oo3s~ Therefore, it can be seen from the above description that the spa cover lifting device is advantageous over prior art designs. The lifting device 10 is versatile such that it can be selectively engageable in a first or a second position on the spa, and can therefore be used with many different types of spas. Also, the lifting device 10 is simple in construction with a minimum number of overall parts, and is space efficient requiring less material for construction. Thus, the lifting device 10 is relatively inexpensive. Furthermore, the lifting device 10 is simple to install and operate.
(00371 The above description is meant to be exemplary only, and one skilled in the art will recognize that changes may be made to the embodiments described without department from the scope of the W vention disclosed. Still other modifications which fall within the scope of the present invention will be apparent to those skilled in the art, in _g_ light of a review of this disclosure, and such modifications are intended to fall within the appended claims.

100181 The spa cover 14 shown in its folded position in Figs. 1 and 2 is designed to complement the spa shape and sit on the top 18 of the spa 12 to insulate and protect the spa water. The spa cover 14 is commonly provided in two parts 20, preferably in halves, that are connected along a folding joint 22. The folding joint 22 is frequently formed by a flexible material. More particularly, the flexible casing material encapsulating the insulation within the spa cover 14 is sewn to form a seam between the two encapsulated foam parts 20.
~ools~ Referring now to Fig. 3, a preferred embodiment of the lifting device 10 is illustrated. The lifting device 10 generally comprises a pivoting assembly 24 operatively attached at respective ends thereof 26 to a pair of brackets 28 for pivotal movement. The pivoting assembly 24 is pivotally movable from a first position with the spa cover 14 seated on the top 18 of the spa 12, to a second position with the spa cover folded over at the folding joint 22 and raised adjacent the spa. Preferably, the pivoting assembly 24 in the second position supports the spa cover 14 such that it is suspended about the pivoting assembly 24 folded at the folding joint 22 thereof. The pivoting assembly 24 is designed to carry the spa cover 14 from a resting position on the top 18 of the spa 12 to a raised position adjacent the spa as shown in Figs. 1 and 2. The raised position is preferably in a substantially vertical orientation adjacent one of the side walls 16 of the spa 12 to minimize space requirements.
100201 It should be noted at this point that the pivoting assembly 24 depicted in Figs. 1 to 3 is merely one possible configuration thereof. Generally, the pivoting assembly 24 comprises opposed side members 30 joined by a coupler 32 in a U-shaped formation. The side members 30 are each pivotally mounted to one of the brackets 28 at their respective ends 26.
100211 More specifically, the pivoting assembly 24 is preferably provided in multiple segments to form a kit so as to minimize the storage space required and thereby facilitate transportation of the lifting device 10. The pivoting assembly 24 kit includes the side members 30 provided as three separate segments: a pair of upper L-shaped corners 34 joined to a pair of lower L-shaped corners 36 respectively by vertical couplers 38.
The coupler 32 is adapted to be horizontally oriented, with respect to a flat surface on which the spa 12 is seated, and to join the pair of upper L-shaped corners 34.
As clearly shown in Fig. 3, the lower L-shaped corners 36 are positioned in a plane parallel to opposed side walls 16 of the spa 12 about which the brackets 28 are mounted, and perpendicular to the plane in which the remaining segments of the pivoting assembly 24 are positioned. Furthermore, the lower L-shaped corners 36 rest on the surface on which the spa 12 is rested by means of respective adjustable stoppers 37.
(00221 Notably, the side members 30 and coupler 32 are tubular to favor a light weight pivoting assembly 24. Thus, the open ends 26 of the pivoting assembly 24, and more specifically of the lower L-shaped corners 36, are capped to prevent the entrance of debris or water therein and to yield a more aesthetically pleasing design.
Caps 39 are preferably press-fit into the open ends 26.
(00231 Therefore, the distance between the side members 30 can be adjusted in accordance with the width of the spa cover 14 to permit the pivoting assembly 24 to connect with the brackets 28 located in spaced relation at opposed sides of the spa 12.
During installation, the pivoting assembly 24 is adjusted such that when in the first position the horizontal coupler 32 is aligned with the folding joint 20 of the spa cover 14, adjacent thereto. Thus, positioning the pivoting assembly 24 as such enables the spa cover 14 to be folded over the coupler 32 for removal thereof, and to be suspended over the coupler 32 for upright storage adjacent one side of the spa 12 when the pivoting assembly 24 is in the second position. Furthermore, the configuration of the pivoting assembly 24 having one end of the lower L-shaped corners 36 pivotally attached to the brackets 28 respectively, as best shown in Fig. 3, advantageously allows for the spa cover 14 to be minimally elevated during removal thereof. Thus, the design of the side members 30 allows for the spa cover 14 to be suspended proximal to the spa 12 and conveniently at a lower vertical position than would be the case if a straight side member were employed.
(00241 The multiple segments are adjusted and secured together during installation via fixation means. Particularly, the upper and lower L-shaped corners 34 and 36 have a series of holes 40 for receiving self tapping screws 42 that fixedly connect the horizontal and vertical couplers 32 and 38 respectively thereto. The couplers 32 and 38 are preferably slightly smaller in diameter than the corners 34 and 36 and are thus installed by telescopic insertion partly into the latter segments. Naturally, other fixation means commonly know in the art can also be used.
(00251 At this point it should be stated that the pivoting assembly 24 can also be provided in another embodiment without the coupler 32. Thus, the upper L-shaped corners 34 can engage the spa cover 14 at the folding joint 22 allowing the lifting device to function in a similar fashion as above-described. Preferably, in this alternative embodiment the folding joint 22 is provided with a sleeve (not shown) for receiving the free ends of the upper L-shaped corners 34.
(oo2s1 Now referring concurrently to Figs. 1 through 5, the brackets 28 of the spa cover lifting device 10 can be seen both installed on the spa 12 and separately therefrom.
In the preferred embodiment, the pair of brackets 28 are configured to be mounted on opposite sides of the spa 12 in one of a first and a second position. The pair of brackets 28 in the first position are horizontally oriented adapted to be inserted under the spa 12.
The pair of brackets 28 in the second position are vertically oriented adapted to be mounted to opposite side walls 16 of the spa 12. Preferably, the brackets 28 are vertically mounted to the base of the opposite side walls 16, proximal to the surface on which the spa is rested to keep the vertical position of the spa cover 14 when suspended to a minimum.
(00271 As illustrated in Figs. 1 and 2, the brackets 28 are configured to be mounted beneath the under surface 17 the spa 12 at opposite sides thereof, such that the brackets 28 are maintained in position by the weight of the spa 12 once the spa is filled with water. It should be understood that during installation, the brackets 28 should be inserted under the spa 12 when it is empty.
(oo2sl It is preferable that the brackets 28 are substantially identical and positioned in mirror relation to one another with respect to the spa 12;
therefore, only one bracket 28 will be described in detail with the understanding that the same description applies to the other.
(oo2s1 Referring concurrently to Figs. 4 and 5, a preferred embodiment of a bracket 28 for use in a spa cover lifting device 10 is illustrated. The bracket 28 comprises a substantially flat, elongated member 44 with respective ends 46, 48. The elongated member 44 defines a top and a bottom surface 50 and 52 respectively. The bracket 28 further comprises a suppouting member 54 projecting from the top surface 50 at one end 48 of the elongated member 44. The supporting member 54 has first and second attachment sites 56 and 58 respectively adapted to be pivotally engaged with one of the side members 30 of the pivoting assembly 24 of the spa cover lifting device 10. The first attachment site 56 defines a first pivot axis 60 substantially parallel to a plane defined by the elongated member 44 and proximal to the top surface 50 thereof. The second attachment site 58 defines a second pivot axis 62 substantially perpendicular to the plane defined by the elongated member 44.
(00301 The bracket 28 is selectively engageable with the spa 12 in one of a first and second position as depicted in Figs. 4 and 5 respectively. The bracket 28 in the first position is adapted to be inserted under the spa 12 with the spa 12 seated on the top surface 50 of the elongated member 44 and the supporting member 54 adjacent a side wall 16 of the spa 12. The bracket 28 in the second position is adapted to be mounted to a side wall 16 of the spa 12 with the supporting member 54 projecting away from the side wall 16. In this exemplary embodiment the bracket 28 selectively engaged in the first position is horizontally oriented and selectively engaged in the second position is vertically oriented.
(oo3i1 Still referring concurrently to Figs. 4 and 5, it can be seen that the supporting member 54 has a prismatic shape. Preferably, it is provided as an inverted U
construction projecting from the top surface 50 of the elongated member 44.
The supporting member 44 includes a first, a second and a third section 64, 66 and respectively, preferably intersecting at substantially right angles to form an inverted U
constmction. More specifically, the first section 64 projects vertically from one end 48 of the elongated member 44. The second section 66 projects horizontally from the first section 64 in parallel relation to the elongated member 44. The third section 68 extends substantially vertically from the second section 66 towards the top surface 50 in parallel relation to the first section 64. The third section 68 has a horizontal extension 70 that rests flush on the top surface 50 of the elongated member 44 to reinforce the supporting member 54. The extension 70 is fixed to the top surface 50 by way of adhesive or other fixation means commonly known in the art. Preferably, the supporting member 54 is an integral extension from the elongated member 44 such that the bracket 28 is substantially fabricated from a single piece of material bent into shape. The bracket design of the preferred embodiment is simple and compact. Thus, the bracket 28 can be inexpensively manufactured.
(00327 Fuuthermore, the first and second attachment sites 56 and 58 are disposed on the first and second sections 64 and 66 respectively. The first and second attachment sites 56 and 58 are selectively engageable with one of the side members 30 of the pivoting assembly 24 by way of threaded fasteners 72. It should be understood that only one of the first and second attachment sites 56 and 58 is selectively engaged during installation of the spa cover lifting device 10, the selection between the two depending on the desired bracket 28 position. When the bracket 28 is in the first position, the first attachment site 56 is selectively engaged and when the bracket 28 is in the second position, the second attachment site 58 is selectively engaged.
(00331 More specifically, the first and second attachment sites 56 and 58 define respective apertures 74 and 76 for selectively receiving a pin 78 in alignment with the selected one of the first and second pivoting axis 60 and 62 respectively. The threaded fasteners 72 as seen in Figs. 4 and 5 include threaded pin 78 that is adapted for insertion through a pair of opposing circumferential holes 80 defined at the end 26 of the lower L-shaped corner 36 and through the selected aperture 74 or 76. The axis detined through the holes 80 is perpendicular to the axial direction of the tubular corner 36.
Also included is a pair of spacers 82 with central holes 84 and semi-circular receiving portions 86 that is adapted to mate with the tubular corner 36 on opposite side thereof in alignment with holes 80. A pair of washers 88 and a nut 90 are also included Such that one of the washers 88 is positioned between the head of the pin 78 and one of the spacers and the other is positioned between the nut 90 and the inside surface of the second section 66 of the supporting member 54. Finally, a rounded pin head cap 92 is preferably provided to create a smooth surface by hiding the angular edges of the pin 78 head. The pin head cap 92 also helps create an aesthetically pleasing design.
[00341 Still referring concurrently to Figs. 4 and 5, it can be seen that the elongated member 44 of the bracket 28 is provided with a plurality of aperhires 94 for receiving fasteners (not shown) therethrough such that the bracket 28 can be mounted to a side wall 16 of the spa 12. Preferably, a gasket 96 configured to complement the shape of the elongated member 44 of the bracket 28 is provided for mating flush with the bottom surface 52 thereof. The gasket 96 is provided with a plurality of apertures 98 for alignment with apertures 94 of the elongated member 44. Thus, the gasket 96 is adapted to be mounted between the side wall 16 of the spa 12 and the bottom surface 52 of the bracket 28 such that the fasteners are inserted through the aligned apertures 94 and 98.
The gasket 96 acts as a protective layer for preserving the side wall 16 surface of the spa 12 and as a seal for keeping the fasteners (not shown) dry to prevent rust formation.
(00351 The gasket 96 can also be used when the bracket 28 is selectively engaged beneath the under surface 17 of the spa 12. Notably, the bracket 28 and gasket 96 do not need to be fastened via fasteners in this position as the weight of the spa 12 prevents movement thereof; therefore, the gasket 96 acts as a protective layer.
Preferably, the gasket 96 is made from an elastomeric material to ensure sealing capabilities.
The material selected is also preferably pliable.
~oo3s~ Therefore, it can be seen from the above description that the spa cover lifting device is advantageous over prior art designs. The lifting device 10 is versatile such that it can be selectively engageable in a first or a second position on the spa, and can therefore be used with many different types of spas. Also, the lifting device 10 is simple in construction with a minimum number of overall parts, and is space efficient requiring less material for construction. Thus, the lifting device 10 is relatively inexpensive. Furthermore, the lifting device 10 is simple to install and operate.
(00371 The above description is meant to be exemplary only, and one skilled in the art will recognize that changes may be made to the embodiments described without department from the scope of the W vention disclosed. Still other modifications which fall within the scope of the present invention will be apparent to those skilled in the art, in _g_ light of a review of this disclosure, and such modifications are intended to fall within the appended claims.
