Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates to the field of collapsible, folding tables. More specifically, the invention relates to collapsible, folding massage tables with folding leg assemblies and stabilizing features that increase load capacity of the massage tables.




2. Description of Related Art




Collapsible tables with foldable leg braces are generally known and practiced in the art. These collapsible folding tables have some distinct advantages over conventional tables because they can be transported to various locations more easily and can be stored in small spaces. Such portability and small size is very important to various professional trades such as massage services where massage practitioners who visit numerous clients at various locations need specialized massage tables to provide their services. The collapsible folding massage table is often transported in the massage practitioner's vehicle from one location to another and carried and set up by the massage practitioner at the client's location. Therefore, such collapsible folding massage table must be portable, small, light weight and easy to set up and collapse.




One of the disadvantages of such collapsible, folding table is that it is not as strong or structurally stable as a conventional table. The joints and hinges used to allow the table to be collapsible and foldable also decrease the structural rigidity of the table and diminish the table's strength and stability. This weakness and instability is especially problematic for a massage table because clients lay on the table surface when the massage practitioner provides his or her services. Thus, if the table collapses or if the table is unstable, the client will fall off the table and will likely to be injured. Consequently, the collapsible table must also have high strength, rigidity and stability so that it will not collapse during use.




In addition, to facilitate their use, massage tables having mechanisms that automatically erect the legs of the table as the table is unfolded has been also created. For example, U.S. Pat. No. 4,833,998 to Everett et al. discloses a collapsible massage table with two table top sections that are hingedly connected and two pairs of legs hingedly connected to the table top sections. Each leg is supported by a foldable leg brace having two brace members hingably connected together, an end of the first brace member being attached to the leg and an end of the second brace member being attached to a table top section. The table disclosed also includes cable leg which extends downwardly from a table top section and a pair of cables interconnecting the upper corners of the table top section via the cable leg. However, because the foldable leg braces and their components are typically made of a heavy rigid material, it has been found that Everett's tables are relatively heavy thereby diminishing their portability. In addition, it has been found that Everett's tables are relatively expensive because of the amount of materials used in the numerous foldable leg braces and because of the associated costs of assembling these leg braces and attaching them to the massage table. Furthermore, while providing adequate support for light loads, this table design has been found to be inadequate for supporting very heavy loads unless the brace members are made even more robust which has the disadvantage of further increasing costs and weight.




Moreover, it has been found that the foldable leg braces, the pair of cables as well as the cable leg provided in the Everett table all limit access underneath the massage table when the massage table is unfolded. In particular, because these components extend substantially up to the peripheral edges of the table top sections, massage practitioners cannot use the space underneath the table top sections when such use is desirable. For instance, in certain circumstances, it may be desirable for the massage practitioner to place his/her leg, thigh and/or foot underneath the table in order to attain a stance which will allow exertion of additional force for proper massaging of the client laying on the table surface. In another instance, the massage practitioner may want to sit down on a chair or a small stool with his/her knees underneath the table so that a light massage may be given without tiring the legs massage practitioner. Because the foldable leg braces, the pair of cables as well as the cable leg all limit access underneath the massage table, the massage practitioner cannot attain such positions and cannot properly massage the client when such prior art tables are used. Thus, the above noted disadvantages of this and other conventionally designed massage tables diminish their appeal and utility.




An alternative massage table design is shown in U.S. Pat. No. 5,335,676 to O'Brien where sliding cables are used to erect the table legs when the massage table is unfolded and also to support the table legs under load. The table disclosed includes a v-shaped truss which support the sliding cables and improve accessibility to the space underneath the midportion of the massage table in the region where the two table top sections are hinged. However, the table still includes a set of first cables that extend from a midportion of the legs to the tip of the truss that substantially impede accessibility to the space underneath the massage table in other regions of the table such as underneath each of the two table top sections themselves. Moreover, it has been found that the numerous sliding cables in the table in accordance with O'Brien stretch under load thereby causing the table to be unstable. This stretching of cables has been found to be even more pronounced under high loads thereby rendering O'Brien's table inadequate for supporting large loads such as the weight of a person. Thus, similar to the other prior art massage tables, the limitations in stability and load carrying capacity as well as limited accessibility to the space underneath the massage table diminishes the O'Brien table's appeal and utility.




Therefore, there is a substantial and unfulfilled need for an improved collapsible, folding massage table which is easy to set up and collapse. There is also an unfulfilled need for such an improved collapsible folding massage table with reduced weight and reduced cost. In addition, there is an unfulfilled need for an improved collapsible folding massage table which is rigid and stable, even under heavy loads. Lastly, there is also an unfulfilled need for such an improved collapsible folding massage table which provides improved accessibility to the space underneath the massage table.




SUMMARY OF THE INVENTION




In view of the foregoing, it is an object of the present invention to provide an improved collapsible foldable table that is easy to set up and collapse.




A second object of the present invention is to provide an improved collapsible foldable table with reduced weight and reduced cost.




Another object of the present invention is to provide an improved collapsible foldable table that is structurally rigid and stable, even under heavy loads.




Yet another object of the present invention is to provide an improved collapsible foldable table which provides improved accessibility to the space underneath the massage table.




In accordance with one embodiment of the present invention, these and other objects are obtained by a collapsible, foldable table including at least two table top sections, at least one hinge connecting the table top sections to allow the table top sections to be moved between a working configuration where the table top sections are co-planar and a collapsed configuration where the table top sections are folded into a substantially parallel orientation, a plurality of table legs rotatably attached to the table top sections, and a set up and rigidifying means for outswinging the plurality of table legs into an extended position as the table top sections are unfolded and for maintaining the table top sections in their co-planar position even when subjected to substantial forces. The set up and rigidifying means includes a pair of bracing means for supporting the plurality of table legs in their extended position when the pair of bracing means are moved to an operative position, at least one of the pair of bracing means including a brace member, a central brace member, and a pivoting means for pivotally connecting the v-brace member to the central brace member. The set up and rigidifying means also includes a central cable extending between the pair of bracing means, the central cable being adapted to cause the outswinging of the plurality of table legs into an extended position when the table top sections are unfolded.




In one preferred embodiment of the collapsible, foldable table, both bracing means includes a v-brace member, a central brace member, and a pivoting means for pivotally connecting the v-brace member to the central brace member. The v-brace member may be hingably attached to at least two table legs and the central brace member may be hingably attached to one of the table top sections. In this embodiment, the central cable may extend between the pivoting means of the pair of bracing means. In addition, the central cable may extend from the pivoting means to the table top sections thereby preventing over displacement of the pivoting means. Moreover, the pivoting means for each of the pair of bracing means may be a molded pivoting member adapted to be affixed to an end of the central brace member, the pivoting means also having a through hole sized to receive the v-brace member. Of course, in other embodiments, the pivoting means may alternatively include a hinge pin that hinges the central brace member and the v-brace member together.




In yet another embodiment of the collapsible, foldable table in accordance with the present invention, the set up and rigidifying means may further include a truss member that extends from at least one of the at least two table top sections, a midportion of the central cable being attached to an end of the truss member. Additionally, in this embodiment, the set up and rigidifying means may further include a first reinforcing cable and a second reinforcing cable, the first and second reinforcing cables each extending from one table top section to the other table top section and the midportions of the first and second reinforcing cables being fixedly attached to an end of the truss member.




In another embodiment of the present invention, the at least one hinge connecting the table top sections may include an integral brace attaching means for hingably attaching the central brace member. In this regard, the at least one hinge may include a plurality of brackets for attachment to the table top sections, the plurality of brackets being hingably joined together to allow the table top sections to be pivoted relative to one another. The at least one hinge may also include a receiving means integrally formed from at least one of the plurality of brackets for receiving and hingably attaching an end of the central brace member.




Similarly, in yet another embodiment, the at least one hinge connecting the table top sections may include an integral truss attaching means for hingably attaching the truss member. The at least one hinge may include a plurality of brackets for attachment to the table top sections, the plurality of brackets being hingably joined together to allow the table top sections to be pivoted relative to one another. The at least one hinge may also include a receiving means integrally formed from at least one of the plurality of brackets for receiving and hingably attaching an end of the truss member.




These and other objects, features and advantages of the present invention will become more apparent from the following detailed description of the preferred embodiments of the invention when viewed in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS





FIG. 1

illustrates one embodiment of an improved collapsible, folding massage table


10


in accordance with the present invention which is easy to set up and collapse. As will be discussed herein below, the massage table


10


provides significant reduction in weight and cost over prior art massage tables while providing rigid and stable massage surface, even under heavy loads. Moreover, the massage table


10


provides significantly improved accessibility to the space underneath the massage table


10


as compared to prior art massage tables thus improving the utility and desirability of the massage table


10


.




As can be seen,

FIGS. 1 and 2

illustrates a massage table


10


in accordance to the preferred embodiment of the present invention that includes a pair of hingedly-connected table top sections


12


and


12


′, illustrated in their operative co-planar position, and four substantially identical table legs


14


(only two being shown) which are pivotally connected adjacent each of the four outer corners of the table top sections


12


and


12


′. The massage table


10


is further provided with an automatic set up and rigidifying mechanism


16


for outswinging all four table legs


14


into operative extended positions as the table top sections


12


and


12


′ are unfolded into their the co-planar position illustrated. In addition to simplifying set up, the automatic set up and rigidifying mechanism


16


further automatically actuates a unique undergirding system of braces, a truss and cables to maintain the table top sections


12


and


12


′ in their co-planar operative position, even when subjected to loading and forces that would cause sagging or even failure in more conventional folding table designs. Moreover, the massage table


10


in accordance with the present invention provides significantly improved accessibility to the space underneath the massage table


10


as compared to prior art massage tables thereby significantly improving the utility and desirability of the massage table


10


.




As can be more easily seen in

FIG. 3

which is a cross-sectional view of the massage table


10


, each table leg


14


is rotatably attached to one of the outer comers of a table top sections


12


and


12


′ via a leg block


16


or other appropriate table structure. The pair of table legs


14


which are rotatably attached to the same table top section further support one another by cross members


17


which provide lateral strength and stability to the legs. Furthermore, the table legs


14


of the embodiment shown in

FIGS. 1 and 3

are adjustable type so that the heights of the table top sections


12


and


12


′ may be adjusted. In this regard, the table legs


14


may be made of an adjustable leg member


15


that can be used to raise the standing height of the massage table


10


by aligning the alignment holes


19


and setting the position with a retaining pin (not shown). Whereas in the illustrated embodiment, these table legs


14


(including the adjustable leg member


15


) and the cross members


17


are made of aluminum tubes, these components may also be made of wood, composites, plastics and/or other sufficiently strong, and preferably light weight material, in any combination.




The table legs


14


of the massage table


10


in accordance with the present invention are further supported by a pair of braces


18


which support the table legs


14


when the pair of braces


18


are moved to an operative position. Each of the braces


18


includes a v-brace member


20


, a central brace member


22


, and a pivoting member


24


, the brace members being more clearly shown in FIG.


4


. The central brace member


22


is hingably attached at one end to the underside of a table top section and pivotally attached at the other end to a radially angled corner end


21


of the v-brace member


20


via the pivoting member


24


. The central brace member


22


may be attached to the underside of a table top sections


12


and


12


′ in the manner discussed in further detail below. The v-brace member


20


is also hingably attached to two table legs


14


which are attached to the same table top section thereby further providing lateral reinforcement and support for the table legs


14


and correspondingly, the massage table


10


.




As can be seen, the v-brace members


20


converge such that the radially angled corner end


21


is positioned at the center midportion of the table top sections


12


and


12


′ and substantially align with a longitudinal axis LA of the massage table


10


. The pivoting member


24


which is more clearly illustrated in the enlarged view of

FIG. 5

, is provided at the radially angled comer end


21


to pivotally attach the central brace member


22


to the v-brace member


20


. As can be appreciated, the automatic set up and rigidifying mechanism


16


in accordance with the present invention eliminates an extra brace member used in prior art massage tables thereby decreasing weight and cost of the massage table


10


. At the same time, the massage table


10


in accordance with the present invention maintains the structurally rigid brace members to avoid the limitations and cable stretching problems of prior art all cable systems.




In addition, as can also be seen, the v-brace members


20


allow the central brace members


22


to be centrally attached to the underside of the table top sections


12


and


12


′ in a substantial alignment with the longitudinal axis LA which is positioned away from the edges


26


of the massage table


10


thereby providing the massage practitioner significantly improved accessibility to the space underneath the massage table


10


as compared to prior art massage tables. Since there are no rigid brace members proximate to the edges


26


in the midportions of the massage table


10


when the massage table


10


is unfolded into an operative configuration, the massage practitioner can use the space underneath the massage table


10


to provide improved massage services thereby improving the utility and desirability of the massage table


10


. In particular, the massage table


10


in accordance with the present invention allows the massage practitioner to place his/her leg, thigh and/or foot underneath the table in order to attain a proper stance for performing certain massage techniques and also allows the massage practitioner to sit down on a chair or a small stool with his/her knees underneath the massage table


10


.




In this embodiment, the central brace member


22


and the v-brace member


20


are made from aluminum tubes. However, it should be appreciated that these components may also be made of wood, composites, plastics and/or other sufficiently strong, and preferably light weight material, in any combination. In addition, as can be seen, the v-brace member


20


is preferably made of a single piece aluminum tube which has been radially bent into a v-shape. This single piece aluminum tube construction provides additional structural rigidity and strength to the v-brace member


20


and also to the table legs


14


which they support. In other embodiments however, these components may be made from a different material and the v-brace member


20


may be constructed from two or more pieces. Moreover, in the present embodiment as most clearly shown in

FIG. 5

, the pivoting member


24


is a molded component member adapted to be affixed to an end of the central brace member


22


such as by plug member


27


. The pivoting member


24


also has a through hole


25


which is sized to receive and pivotably retain the v-brace member


20


. Of course, in other alternative embodiments, the central brace member


22


and the v-brace member may be pivotally attached by different pivoting means such as a via a hinge and/or hinge pin.




The massage table


10


accordance with the preferred embodiment of the present invention also includes a central cable


28


extending between the pair of braces


18


which is adapted to cause the outswinging of the plurality of table legs


14


into an extended position when the at least two table top sections


12


and


12


′ are unfolded. In particular, in the embodiment shown, the central cable


28


extends between the pivoting members


24


of the pair of braces


18


and are attached to the pivoting members


24


as shown in FIG.


5


. Because the central cable


28


is of a fixed length and attached to the pivoting members


24


of the pair of braces


18


, when the at least two table top sections


12


and


12


′ are unfolded, the central cable


28


causes the pair of braces


18


to be hinged into an operative position shown thereby causing the plurality of table legs


14


to be erected into the operative position. In this manner, the central cable


28


facilitates the setup of the massage table


10


by unfolding the plurality of legs


14


and erecting them automatically when the hingably connected table top sections


12


and


12


′ are unfolded to a co-planar position. Correspondingly, the central cable


28


also prevents any upward folding of each of the pair of braces


18


when the table top sections


12


and


12


′ are unfolded to a co-planar position thereby preventing the plurality of table legs


14


from collapsing when the massage table


10


is being used.




As can also be seen in

FIGS. 4 and 6

, the central cable


28


also extends from the pivoting members


24


to the table top sections


12


and


12


′ to prevent the over-displacement of the pivoting members


24


. In this regard, an end of the central cable


28


is fixedly attached to the table top section


12


by a retaining member


30


as most clearly shown in FIG.


6


. Thus, when the pair of braces


18


are hinged into an operative position, the central cable


28


is tensioned between the pivoting members


24


and the table top sections


12


and


12


′ thereby preventing the over-displacement of the pivoting members


24


so as to maintain the operative positions of the pair of braces


18


, i.e. the central brace member


22


and the brace member


20


. In the preferred embodiment, the central cable


28


shown is a single piece cable attached to the pivoting members


24


at intermediary portions of the cable as shown in FIG.


5


.




Of course, while the details of the central cable


28


and its attachment in the preferred embodiment is discussed above, the present invention is not limited thereto. For instance, while in the illustrated embodiment, the central cable


28


is attached to the pivoting members


24


, in other embodiments, the central cable


28


may also be attached at locations on the braces


18


which is slightly offset from the pivoting members


24


. However, attachment of the central cable


28


at the pivoting members


24


is preferred since it minimizes the forces required to hinge the pair of braces


18


into an operative position. In addition, whereas the central cable


28


itself is used to prevent the over-displacement of the pivoting members


24


, other means may also be used such as a displacement limiting flange or other mechanisms. Moreover, the central cable


28


need not be a single unitary cable but instead, may be separate cables attached between the pivoting members


24


and between the pivoting members


24


and the table top sections


12


and


12


′. However, the use of a single unitary cable is preferred since this allows the minimization of material and assembly costs as well as ensuring compact and simple packaging of the components.




As shown in

FIGS. 1-4

, the set up and rigidifying mechanism


16


in the illustrated preferred embodiment of the collapsible, foldable massage table


10


, further includes a truss member


32


that extends downwardly from at least one of the two table top sections


12


and


12


′. As can be most clearly seen in

FIG. 2

, the truss member


32


is also v-shaped such that it converges away from the edges


26


of the massage table to an end


33


thereby providing the massage practitioner with easy accessability to the area underneath the massage table


10


. A midportion of the central cable


28


may be attached to the end


33


of the truss member


32


via a crimped retainer (not shown) so that better management of the central cable


28


and hinging of the pair of braces


18


into an operative position are attained. Again, the truss member


32


shown may be made of an aluminum tube or other materials such as wood, composites and/or plastics.




Additionally, as most clearly illustrated in

FIG. 4

, the set up and rigidifying mechanism


16


further includes a first reinforcing cable


34


and a second reinforcing cable


34


′ that extend from a comer of one table top section


12


to the corner of the other table top section


12


′ in the manner shown. The midportions of the first and second reinforcing cables


34


and


34


′ are fixedly attached to the end


33


of the truss member


32


via crimped retainers (not shown). The mounting of the first reinforcing cable


34


to the comer of the table top section


12


is better illustrated in FIG.


7


. As can be seen, the first reinforcing cable


34


is wrapped into a loop around a circular member


36


and affixed using a retainer


38


thereby securing the first reinforcing cable


34


such that it increases the structural rigidity and load carrying capacity of the massage table


10


. The second reinforcing cable


34


′ is also attached in a similar manner to further increase the structural rigidity and load carrying capacity of the massage table


10


. In this regard, as weight is placed upon the surface of the table, the weight is transferred to the truss member


32


. Because the first and second reinforcing cables


34


and


34


′ are fixedly attached to the end


33


of the truss member


32


, any tendency to downwardly displace the truss member


32


is resisted by the tensioning of the first and second reinforcing cables


34


and


34


′ as well as the pair of braces


18


. Thus, the illustrated massage table


10


having the first and second reinforcing cables


34


and


34


′ have substantially increased load carrying capacity as compared to a massage table which does not incorporate such reinforcing cables. In laboratory testing, the present inventors have found that the presently illustrated preferred embodiment of the massage table


10


with the first and second reinforcing cables


34


and


34


′ exhibits substantially increased load carrying capacity over the prior art tables while at the same time, being lighter in weight and more economical in cost.




Moreover, in accordance with the illustrated embodiment, the first and second reinforcing cables


34


and


34


′ do not substantially impede the massage practitioner's access to the area underneath the massage table


10


. In particular, as can be clearly seen in

FIGS. 1 and 4

, the first and second reinforcing cables


34


and


34


′ converge together and away from the edges


26


of the massage table as they downwardly approach the end


33


of the truss member


32


to which they are attached. This provides the massage practitioner with easy accessability to the area underneath the massage table


10


at the midportion of the unfolded table. As shown in

FIG. 4

, the first and second reinforcing cables


34


and


34


′ are positioned more closely to the edges


26


of the massage table closer to the corners of the table top sections


12


and


12


′ where they are also attached. However, as most clearly shown in

FIG. 2

, because the reinforcing cables are positioned progressively closer to the table top sections


12


and


12


′ as the comers of the table top sections are approached, the cables do not substantially impede the access to the area underneath the massage table


10


. Thus, in the above described manner, the first and second reinforcing cables


34


and


34


′ in accordance with the illustrated embodiment of the massage table add to the load carrying capacity of the massage table


10


while providing minimal negative impact to the massage practitioner's access to the area underneath the massage table


10


.




In accordance with the illustrated embodiment of the present invention, the table top sections


12


and


12


′ are hingably attached together by an optional integral hinge


40


and optional integral hinges


50


which are discussed in further detail herein below. In particular, the integral hinge


40


which is most clearly shown in

FIGS. 8A and 8B

, includes a plurality of brackets


44


which are attached to the table top sections


12


and


12


′ via fasteners


41


. The plurality of brackets


44


are hingably joined together by a hinge


46


that allow the table top sections


12


and


12


′ to be pivoted relative to one another. The integral hinge


40


also includes a receiving area


42


integrally formed from the plurality of brackets


44


for receiving and hingably attaching an end of the central brace member


22


via fasteners


48


. Thus, the integral hinge


40


combines the functions of a conventional hinge with the functions of a brace attachment in a single, lighter, stronger and more compact component. In addition, because the central brace member


22


is directly connected to the integral hinge


40


via the receiving area


42


and the fasteners


48


, the central brace member


22


gives direct support to forces exerted on the integral hinge


40


thereby providing increased strength to the attachment of the two table top sections


12


and


12


′ and increased structural stability and rigidity of the present massage table


10


.




Similarly, the integral hinge


50


which is most clearly shown in

FIGS. 9A and 9B

, includes a plurality of brackets


54


which are attached to the table top sections


12


and


12


′ via fasteners


51


. The plurality of brackets


54
