## Abstract

The present invention relates to the concept of a tripod having three separate legs which can placed on a surface such as the ground and which come together at a joint location at the top portion of the legs to retain a support member to which a piece of photographic equipment such as a camera can be attached. The present invention relates specifically to the field of photography tripod support equipment which contains tripod legs wherein each leg of the tripod is composed of a multiplicity of sections which can be folded up and retained in the folded condition for transport and thereafter, can be converted to legs which are immediately in the in-use condition after the mechanism which retains the legs in the folded condition is released to permit the three tripod legs to be quickly unfolded and automatically placed into the in-use condition.

## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to the field of tripods which are used to support photographic equipment. In particular, the present invention relates to the field of tripods wherein the legs of the tripod can be folded into a multiplicity of sections to facilitate transport and thereafter have the legs converted to an opened condition for use to support a camera or other photographic equipment at a given location.
2. Description of the Prior Art

The Davis patent discloses a collapsible tripod stool. Specifically, this patent discloses:

    
    
        “A collapsible tripod stool for bodily and tangible item support is described. The triangularly shaped seat is supported by a plurality of tubular legs, which may be fused, glued, or otherwise connected to the corners of the seat. In one embodiment, telescoping legs are comprised of upper, central, and lower sections, the central leg section having two different diameters to prevent section contact, and being case as one piece to eliminate welded surfaces. The central leg sections are attached to a triangularly-shaped central pivot joint by threaded members to prevent mobilization of the legs with respect to one another. The telescoping legs are angled to maximize ground surface contact and further stabilize the tripod stool of the present invention. In another embodiment, tubular legs are comprised of upper and lower sections which connect to one another and are coupled together by an elastic cord within each leg. The leg sections are conveniently detached at their approximate midpoints and folded together in a compact bundle. A pivot join comprises fabric straps secured to each leg and centrally joined to one another.”
    
    


In prior art tripods, the sections of each leg telescope into an adjacent leg with the lowermost section telescoping into the next section and the next section telescoping into a third section etc. until all the legs telescope into the uppermost section. There is a connection which fastens one section relative to another when the legs are moved from the telescoped position to the open position. However, to open and fasten each leg section to another so that the three legs can remain straight involves a lot of time consuming effort. In many cases, there is a requirement for a photographer to instantly have the tripod converted from the folded condition or telescoped condition to the in-use condition so that a shot which may only be available for a few seconds can be made with a camera. Accordingly, the time that it takes to transform a conventional tripod from the closed condition to the open condition is unacceptable where it is necessary to have a quick creation of a fully assembled tripod so that a camera can be used within a matter of seconds to take the appropriate shot. A significant disadvantage of the prior art is that the leg sections are interconnected to each other in a manner which requires each section to be affixed to an adjacent section by means such as a threaded collar which threads from one section to another or a connecting member. Either way, the assembling of the telescope is a time consuming process which is unacceptable for a photographer who needs to be able to have the telescope assembled within seconds so that a photograph can be quickly taken. Therefore, there is a significant need to improve this major deficiency in prior art tripods.
Although the prior art does disclose the general concept of having tripod legs which can be converted from a folded condition to an in-use condition, there is still a significant need for a device that enables the conversion of the tripod legs to the folded condition to the in-use condition to be achieved within a matter of seconds for quick and ready use at a remote location so that a piece of photographic equipment can be quickly mounted to the tripod and placed into the in-use condition.
SUMMARY OF THE INVENTION
The present invention relates to the concept of a tripod having three separate legs which can placed on a surface such as the ground and which come together at a joint location at the top portion of the legs to retain a support member to which a piece of photographic equipment such as a camera can be attached. The present invention relates specifically to the field of photography tripod support equipment which contains tripod legs wherein each leg of the tripod is composed of a multiplicity of sections which can be folded up and retained in the folded condition for transport and thereafter, can be converted to legs which are immediately in the in-use condition after the mechanism which retains the legs in the folded condition is released to permit the three tripod legs to be quickly unfolded and automatically placed into the in-use condition.
It has been discovered according to the present invention that if each of the legs of a tripod is comprised of a multiplicity of sections wherein for each leg, the lowermost section is attached to an end cap or rubber foot by which the section is supported on a surface, and partially within the end cap and extending therefrom is a transverse receiving member having an opening therethrough with an end of a flexible bungee cord extending through the opening and thereafter fastened, and if each of the leg sections is hollow to permit the bungee cord to extend through each respective leg section until the end of the bungee cord is affixed to a connecting pin by which the top section of the leg is attached to the tripod support member which supports photographic equipment, then the tension of the bungee cord will enable all leg sections to immediately align with each other to form a complete leg section within a matter of seconds. The flexible bungee cord also permits each section to be separated from each other and placed into a folded condition so that the leg sections can be retained in the folded condition for transport and thereafter once the leg sections are released from their folded condition, they can immediately be converted to their in-use condition by the tension action of the bungee cord causing each of the leg sections to open and be aligned with each other to form a fully comprised leg section for each of the three legs.
It has further been discovered according to the present invention that if each leg section is comprised of a hollow cylindrical outer wall and has a reduced interior cylindrical wall at one end which is located adjacent to an adjacent leg section, then upon activation of the tension of the bungee cord or flexible cord which retains the leg sections together, the reduced diameter section at one end is immediately inserted into the cylindrical opening of an adjacent leg section to form a secure affixation of one leg section relative to another leg section so that one leg section will not move relative to the other when the entire leg section is formed and is in the in-use condition.
It has further been discovered that to improve the ability of one leg section to be inserted into another, the lowermost section of the reduced cylindrical portion of one leg section has a beveled exterior end and the receiving openings of the adjacent leg section also have a beveled circumferential end so that the beveling enables one leg section to be smoothly inserted into another leg section without catching and without snagging so that the tripod leg sections can be quickly assembled by the tension of the bungee cord.
It has further been discovered according to the present invention that if the three topmost ends of the tripod legs are connected to a mounting base which is used to support a piece of photographic equipment, and the mounting base in turn contains a respective connecting pin by which each respective tripod leg is rotatably connected to the mounting base, then the flexible cord can be attached at the top end of the leg assembly to the mounting pin so that the leg sections can be folded up by virtue of the separation of one section from another but still retained together by the extended flexible cords and after the mechanism by which the legs are retained in the folded condition is released, the legs can be opened to the fully assembled condition by an instantaneous action of the flexible cord causing one leg section to be inserted into another leg section to form a fully assembled leg section for each of the three tripod legs.
It is therefore an object of the present invention to create a tripod assembly which comprises three legs wherein each leg has a multiplicity of separate sections wherein a respective section has a reduced diameter at one end which permits its reduced diameter section to be inserted into the opening of an adjacent section for secure attachment and the assembly can be quickly and automatically converted to a fully assembled leg section because the leg sections are held together by a flexible cord or bungee cord which is affixed at one end of the lowermost leg section and affixed at an upper end of the uppermost connecting section.
It has further been discovered according to the present invention that if the lowermost section comprises an end cap which includes a transverse receiving member with an opening extending therethrough, then the flexible cord can be attached to the transverse receiving member by extending the flexible cord through the opening in the transverse receiving member and tying a knot on the cord so that it is affixed to the transverse receiving member which is retained within the end cap at the lowermost leg section and if the uppermost end of the leg section is rotatably connected to a photographic equipment mounting base through a connecting pin, then the uppermost portion of the flexible cord can be attached to the rotatable connecting pin at the uppermost portion of the uppermost leg section in order to create a strong tension to retain all leg sections together and the fact that the leg sections can be separated by a pulling force to overcome the tension force of the connecting cord enables the leg sections to be folded into a multiplicity of smaller separate sections and retained in the folded condition for transport and upon release of the mechanism by which the legs are retained in the folded condition, the legs automatically will be converted to a fully assembled unitary leg section by virtue of the tension of the flexible cord causing each section to be retained into an adjacent section by virtue of the tension of the flexible cord.
Further novel features and other objects of the present invention will become apparent from the following detailed description, discussion and the appended claims, taken in conjunction with the drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Although specific embodiments of the present invention will now be described with reference to the drawings, it should be understood that such embodiments are by way of example only and merely illustrative of but a small number of the many possible specific embodiments which can represent applications of the principles of the present invention. Various changes and modifications obvious to one skilled in the art to which the present invention pertains are deemed to be within the spirit, scope and contemplation of the present invention as further defined in the appended claims.
The present invention is disclosed in two illustrative alternative embodiments which are shown in FIGS. 1-7 and in the photographs FIGS. 8-16. It will be understood that the two embodiments are simply alternative variations of the present invention tripod to support photographic equipment, wherein there are a different multiplicity of leg sections for each respective leg of the tripod. In the assembly shown in the drawings of FIGS. 1-7, there are three separate sections and in the assembly shown in the photographs of FIG. 8-16, there are four separate sections. However, it will be appreciated that the principles by which the present invention works for both sections are the same.
Referring to FIGS. 1-7, the tripod 10 has three leg sections 20, 30 and 40. Each leg section is broken into a multiplicity of separate sections such as three separate sections 20A, 20B and 20C for leg section 20; 30A, 30B and 30C for leg section 30; and 40A, 40B and 40C for leg section 40. Each leg section is comprised of a cylindrical member surrounding an interior hollow cavity. Within the interior hollow cavity of each section of a leg member is a flexible cord such as a bungee cord which creates a tension when the cord is stretched in the expanded condition. The lowermost sections 20A, 30A and 40A of each respective leg section terminate in a respective end cap 20E, 30E and 40E so that when in the assembled condition, the end cap enables the tripod to be firmly positioned on a horizontal surface such as the ground. Within the end cap is a receiving member which extends through the end cap and into an opening in the adjacent leg section. The receiving member contains an opening and the end of the bungee cord is threaded through the opening and thereafter fastened with a knot so that the bungee cord is affixed to the receiving member which partially extends out of the end cap and extends into the opening of the leg section to which the end cap is affixed.
The uppermost ends 20D, 30D and 40D of each section 20C, 30C and 40C are respectively connected to a connecting pin which in turn rotatably affixes the uppermost section of each leg member to a platform 50 by which each leg is rotatably connected to the platform. The rotation connection mechanism is a connecting pin. The upper end of the bungee cord or flexible cord is affixed to the connecting pin. In this manner, when the legs are in the open condition, a tension is created on the interior bungee cord which enables the legs to be immediately retained in an open condition wherein one leg section is affixed to an adjacent leg section so that the entire leg section is formed to create a fully assembled leg section 20, 30 and 40 so that the tripod is ready for use. A photographic equipment support member is affixed to the connecting pad 90 and by way of example, as illustrated in the drawings of FIGS. 1-7, the photographic equipment connecting member can be a ball quarter 80 and connecting member 70 by which a piece of photographic equipment such as a camera can be affixed to the ball quarter for movement and rotation so that the camera can be oriented in any direction.
The photographs of FIGS. 8-16 provide a more detailed view of the present invention.
Specifically, referring to FIG. 8, the present invention in this embodiment comprises a tripod having three legs wherein each of the legs have four separate sections. In the view of FIG. 8, the legs are in the folded condition so that each leg section is folded against an adjacent leg section so that the entire assembly of each of the three leg sections can be folded into a more compact length and retained together by a folding retention mechanism such as a wrap to retain the legs in the folded condition so that the tripod assembly can be easily transported from one location to another.
Referring to FIG. 9, the tripod assembly is shown in its fully assembled condition where the assembly has four sections. Specifically, the photograph of the tripod assembly 100 comprises three separate legs 120, 130 and 140, which have four separate leg sections 120A, 130A and 140A which are the lowermost leg sections respectively connected to a first intermediate section 120B, 130B and 130C respectively connected with separate intermediate sections 120C, 130C and 140C which in turn are respectively connected to a respective uppermost leg section 120D, 130D and 140D.
A closeup view of a location of two interconnecting sections is shown in the photograph of FIGS. 10, 11, 12 and 13.
Each specific leg section of a leg assembly is comprised of a hollow cylindrical member. Specifically, what is illustrated in FIGS. 10, 11 and 12 is the interconnection location of lowermost leg section 120A and intermediate leg section 120B. The lowermost leg section 120A has an exterior cylindrical wall 120AA and an interior hollow chamber 120AAA which is surrounded by the exterior wall 120AA.
The adjacent leg section 120B has a hollow cylindrical wall 120BB which surrounds the hollow interior chamber 120BBB. At its lowermost end of intermediate interconnecting section 120BB the diameter of the cylindrical wall is reduced so that there is a reduced diameter section 120BBR. The diameter of the reduced diameter section 120BBR is sufficiently small so that it can be inserted into the hollow opening 120AAA of the lowermost section 120A to form a strong press fit so that the two sections are securely retained together. Also illustrated in FIGS. 10, 11 and 12 is a portion of the interconnecting bungee cord 150A.
Referring to FIG. 13, to improve the efficiency by which one leg section is inserted into another, in the preferred embodiment of the interconnection section, the cylindrical circumference of the wall of the receiving opening and the cylindrical circumference of the reduced diameter portion of the adjacent leg section both have beveled circumferential surfaces. Specifically referring to FIG. 13, receiving leg 120A has an exterior circumferential surface at the receiving end, which exterior circumferential surface 120ACB is beveled. Similarly, on the reduced diameter portion 120BBR of the adjacent leg section, its circumferential edge at its end 120BCB is also beveled. In this way, the respective beveling members enable the one adjacent leg to be inserted into another adjacent leg. It will be appreciated that the respective adjacent ends of each leg section have circumferential beveled surfaces to facilitate the insertion of one leg section into another leg section.
Referring to FIG. 9, as shown in the fully assembled tripod, the lowermost sections of each leg 120A, 130A and 140A terminate in an end cap 120AC, 130AC and 140AC respectively so that the tripod can rest firmly on the ground. The end cap slides over the lowermost end of each respective leg section. A closeup of the end cap is shown in FIGS. 14 and 15. Referring to FIG. 14, end cap 120AC has within it an interior circumferential opening 120ACI and a transverse receiving member 120ACR with a receiving opening 120ACRO. One end of the bungee cord 150A is inserted through opening 120ACRO and knotted so that the lowermost end of the bungee cord is affixed to the opening. Thereafter, the end cap is slid over the lowermost portion of the leg section and in this way, the lowermost portion of the bungee cord is affixed in a permanent way. This is also true for respective end caps 130AC and 140AC.
Referring to FIG. 16 there is illustrated a closeup view of the rotatable attachment pin by which the uppermost end of uppermost section 120D is rotatably attached to a tripod platform 150. The uppermost end of flexible cord 150A is affixed to the transverse pin within the interior of the uppermost section 120D. It will be appreciated that the flexible cord 150A extends through the entire length of the four leg sections 120A, 120B, 120C and 120D, so that when the leg sections are in the opened condition, the tension on the bungee cord causes the leg sections to be affixed to one another. It will be appreciated that the same assembly is utilized for each of the other two leg sections 130 and 140. Leg section 130 has four sections, 130A, 130B, 130C and 130D, which are retained together by a separate flexible bungee cord or flexible cord comparable to the cord illustrated in FIGS. 10, 11 and 12 and the cord is affixed to a transverse receiving member retained in end cap 130A on the lowermost portion of the leg and is affixed to a transverse connecting pin 132 by which the uppermost section of leg section 130D is rotatably connected to the transverse platform.
For the embodiment with three sections illustrated in FIGS. 1-7, comparable wrapper members 60 and 50A are on a leg section as illustrated so that the three legs can be folded and tied together in the same manner as discussed above for the four leg section members. It functions exactly the same way in the same manner with the exception that it is used with three leg sections instead of four leg sections.
Leg section 140 has four sections, 140A, 140B, 140C and 140D, which are retained together by a separate flexible bungee cord or flexible cord comparable to the cord illustrated in FIGS. 10, 11 and 12 and the cord is affixed to a transverse receiving member retained in end cap 140A on the lowermost portion of the leg and is affixed to a transverse connecting pin 142 by which the uppermost section of leg section 140D is rotatably connected to the transverse platform.
A closeup view of the leg wrapper member is illustrated in FIG. 17. It will be appreciated that this is only one of many possible connecting members. The wrapper member 200 consists of a body 202 which can rotatably slide on one leg section and has a connecting flexible strap 250 extending through opening 210 and extending through second opening 220 in the body which in turn permits the strap to be wrapped around the three folded leg sections as illustrated in FIG. 18 and thereafter affixed into a slotted opening 220 in the wrapper member 200 so that the connection is securely retained to retain all three leg sections together in the folded condition. While one wrapper member 200 is illustrated, in the preferred embodiment there are two spaced apart wrapper members 200 and 200A on a leg section. The two spaced apart wrapper members are the same leg section and provide a double security retention when the tripod is in the folded condition.
As illustrated in FIG. 19, the flexible straps 250 and 250A of the wrapper members 200 and 200A serve to retain the three leg sections together. As further illustrated in FIG. 19, the flexible strap can also be used to retain the entire folded tripod to a portion of a camera bag such as the handle of a camera bag. In FIG. 19, the camera bag 500 has a handle section 510 with a left side handle section 520 and a right side handle section 530. As shown, the flexible strap 250 of wrapper member 200 can be not only wrapped around the legs, but also wrapped around one handle section 530 and the flexible strap 250A of wrapper member 200A can be wrapped around another portion 520 of the handle section 510 of the camera bag 500 so that the tripod in addition to being retained in the folded condition by the flexible straps of the wrapper member, can also be retained to the handle of a camera bag or other portion of the camera bag to be carried therewith. This eliminates the necessity of having a separate case to carry the tripod or having the tripod take up valuable space within the camera bag.
When in the folded condition, each of the separate bungee cords within the legs are in a stretched but not taut condition so that each section of each leg section is retained together but are retained in the folded condition so that the tripod assembly can be easily transported. When the wrapper member 200 is released from its slotted member 220, the tension on each respective bungee cord or flexible cord within each leg section immediately causes each leg section to extend into the open condition so that one reduced diameter section of a leg section is automatically forced into the opening of an adjacent leg section and the flexible bungee cord retains all four leg sections in a fully assembled condition. Because of the tension on the bungee cord, this action takes place within a matter of seconds. All three legs section are each assembled in to the in-use condition in this manner.
Each leg section is rotatably connected to a platform 150. The platform in turn as illustrated can support a photographic equipment mounting member which as illustrated in the photograph of FIG. 18 are hemispherical sections 300 and 310 which in turn support a rotatable ball member 340 which contains a platform 350 and a threaded member 360 extending through the platform, which threaded member can be threaded into a receiving member on a piece of photographic equipment such as a female threaded opening within a camera. The camera then can be rotated and adjusted to any desired angle based upon the rotation of the ball member 340 and an adjustment means on the ball member. It will be appreciated that the rotatable ball member is only one of many possible photographic attachment means which can be used with the present invention. The essence of the present invention is the tripod assembly wherein the legs can be positioned into a folded condition and retained therein as described above and upon release of the wrapping mechanism can automatically be extended into the in-use condition by the force of the bungee cord causing the leg sections to immediately open with an interior lower diameter section of one leg section forced into the interior chamber of an adjacent leg section and the four leg sections of a leg section retained in a taut condition for use.
While the reduced diameter portion is the preferred embodiment, it will be appreciated that it is also within the spirit and scope of the present invention for each leg section to have the same diameter and not have a reduced diameter portion at a location where it is adjacent another leg section so that in effect, the four leg sections are retained together simply by the force of the flexible cord or bungee cord. However, the reduced diameter feature is an improvement which enables the attachment to be far more secure so that one leg section will not bend relative to another leg section and so that all four leg sections can remain in a very strong secure position to support any piece of heavy photographic equipment which is placed on the photographic equipment attachment assembly at the top of the platform pad.
The present invention therefore enables the tripod to be placed into a folded condition for easy transport and when the mechanism by which the tripod legs are retained together is released, the legs immediately extend and open into the fully in-use condition within a matter of seconds because of the tension of the bungee cord forcing the multiplicity of leg sections together so that the tripod is in the fully assembled condition and ready for use within a matter of seconds.
While the disclosure has shown three leg sections in FIGS. 1-7 and four leg sections in FIGS. 8-18, it will be appreciate that it is within the spirit and scope of the present invention to have any multiplicity of leg sections forming the tripod assembly. While the most efficient way is to have the same number of leg sections on each of the three legs of the tripod, it will be appreciated that it is also within the spirit and scope of the present invention to enable each leg section to have a different multiplicity of leg sections therein. Therefore, one leg section may have three sections and one leg section may have four sections and one leg section may have five sections although the preferred embodiment is to have the same number of sections in each leg.
In the preferred embodiment, the legs are made of metal such as lightweight aluminum, steel or titanium. It is also within the spirit and scope of the present invention to have the leg sections made of strong plastic, strong polyvinyl or carbon fiber.
The preferred retention cord which retains the leg sections together is a bungee cord but it will be appreciated that any lengthwise mechanism which creates a tension to force the leg sections together is within the spirit and scope of the present invention to retain the leg sections in the fully assembled condition and also permit the leg sections to be separated and placed into a folded condition for transport.
Of course the present invention is not intended to be restricted to any particular form or arrangement, or any specific embodiment, or any specific use, disclosed herein, since the same may be modified in various particulars or relations without departing from the spirit or scope of the claimed invention hereinabove shown and described of which the apparatus or method shown is intended only for illustration and disclosure of an operative embodiment and not to show all of the various forms or modifications in which this invention might be embodied or operated.
