The present invention relates to a socket mounted post system. More specifically, the present invention is a crowd control stanchion including a spring mechanism and a miniature socket mounted post that provides for easy installation in a floor with minimal impact to the surface of the floors. The post could alternatively be used in connection with panels, railings, signage, bollards or other types of posts.
A stanchion is a sturdy upright post that provides support for belt, rope, chain or cord that is often used for crowd control or engineering the flow of people. A stanchion system utilizes the upright post which may include a rope support at the top of the post; or, alternatively, it may include a retractable belt. The ropes, chains or retractable belts may be linked together at the stanchions to form a crowd control or crowd flow system. These crowd flow systems are called a queue or a maze. The stanchions are often not intended to be a permanent fixture, so that the post may be expediently implemented or removed, as desired. The stanchion and rope system are typically implemented to form a queue or maze for people to move through.
Typically, the post of a stanchion is typically mounted on a weighted base. There are several problems with a post that is mounted on a weighted base. First, the base often protrudes into the area of the queue or maze in which people walk—often times causing people to trip on the base. Second, the weighted base is movable. If bumped, the base along with the ropes or belts will move causing the queue to become misaligned. Movement of the post interferes with the movement of traffic through the queue. Third, the base takes up valuable floor space and often interferes with movement of carts or language through the queue. The standard base for a stanchion post has a footprint of almost one square foot which is not desirable in space-constrained areas. When several stanchions are employed, the amount of floor space dedicated to the numerous bases becomes quite significant. Fourth, the base is not aesthetically pleasing and may be considered unacceptable given the aesthetic desire of customers. The design of the weighed bases may not be preferred by the owner of the venue implementing the queue. Fifth, the post, along with the base, may be knocked over because the base is not securely mounted to the floor. Finally, since the base and post are not secured to the floor, the base and post may be picked up by a patron and used as a weapon. This is undesirable in any public forum. A typical prior art weighted base stanchion is shown in
Alternatively, the post of the stanchion may be easily removably mounted into the floor of the facility implementing the queue or maze. The floor mounted posts are commonly implemented in applications where the flow of traffic is steady or constant or where portability of the stanchions becomes impractical. The floor mounted solution is not without its own set of problems. For example, the stanchion posts must be mounted into holes in the floor of the venue which are either pre-formed or drilled into the floor after construction. The floor mounted system is not flexible or moveable. The posts can only be positioned within the pre-formed holes within a venue. Worse, the hole depth must be 6 inches or more in order to accommodate the post; and the diameter of the hole is typically 2 to 3 inches or more. The posts are also easily removable and can be used as a weapon by a customer standing in the queue. Finally, in the floor mounted system, the posts are not flexible. The post does not absorb any impact should a person run into a post, or if a piece of luggage or cart is run into a post. Another problem with the easily removeable stanchion post is that when the post is removed, there is a 3 inch diameter by 6 inch deep hole left in the floor.
What is desired, therefore, is a post which may be semi-permanently mounted within the floor of a venue without having to install the standard 3 inch by 6 inch hole deep into the floor. There is also a need for a flexible mounting system between the post and the floor which permits the post to absorb impact to the post. It is, thus, desirable to have a semi-permanent post that has minimal impact on the existing flooring of a venue. Providing a post that is easy to install and that has the ability to flex once installed into the floor is highly desirable.
Accordingly, one of the objects of the invention is to provide a post that does not have a weighted base which provides a cleaner aesthetic and further provides maximum floor space.
A further object of the invention is to eliminate a weighted base from the post to prevent luggage from rolling over the base and moving the post from its desired position.
Another object of the present invention is to provide a semi-permanent securing mechanism to affix the post to the ground which prevents the post from shifting or moving from its desired position in securing the queue or maze and thus causing disorder in the queue lines.
An alternative embodiment of the present invention is to implement a threaded member in the post such that the threaded member engages with threads with the floor to prevent unwanted removal of the post, yet are easily removable for cleaning, re-routing or other reasons for moving the post.
An object of the present invention provides for a spring mechanism that is attached to or included as part of the post to permit the post to move from its vertical position when the post is secured to the mount in the floor. The movement may be any amount, but in situations where there may be an abundance of people, the post may move from the vertical position. The flexibility of the spring mechanism absorbs any impact forces impaired upon the post which can cause an anchor or threaded member to fail.
A further object of the present invention is the use of two interfering tabs which allow for approximately 350 degree adjustment, yet ensure the tension in the spring and securement into the socket to remain intact. This is important for queue posts because the belts must align in some undetermined direction for each layout. The belts may be aligned upon installation of the post, and may be easily rotated to change the configuration of the queue.
Since there is expected movement in the post from the flex and rotational adjustment the edge of the metal posts can cause damage to floors over time. With the addition of a thick nylon wear disc or other protective cap, the floor is protected and all friction from the movement is removed allowing for a softer and smoother functioning unit.
The larger sockets have at least a 3 inch diameter raised flange which is unsightly and becomes a potential tripping hazard. Often times building owners will want the holes for the stanchions to be removed and the floors repaired, thus, adding more cost to the system.
The prior art stanchion 10 has no method of securing the insert portion 50 of the post 14 to the hole 60. There is a simple slip-fit of the insert portion 50 into the top 62 of the floor hole 60. The posts can easily be removed by unauthorized individuals. There have been times where posts have been used as weapons. The prior art systems are more prone to that risk. A cap 64 may be placed in the top 62 of the hole 60.
A second prior art embodiment is shown in
The lower portion of the post 114 includes a spring assembly 300 and base cap 140. The spring assembly is described in more detail below with respect to
The flexible stanchion 110 may be mounted in a wide range of floor 120 materials. As shown in
The post 114 is typically between 40 inches to 72 inches in height. Because of the height of the post 114, accidental contact with the flexible stanchion 110, may cause exceedingly high torsion force to be placed on the pillar 150. The pillar 150 has a smaller diameter than the post 114. As such, the torsional force placed upon the pillar 150 can overcome the shear strength of the pillar 150 material causing the pillar 150 to structurally fail. In some instances, any more than 10 degrees of travel may cause the post 114 to snap back to the vertical position 170 and injure a person.
The socket 200 may be up to 4 inches in depth. The benefit of having a socket approximately 2 inches to 4 inches in depth is that there is less chance of contacting decking rebars, electrical supply lines, plumbing or other utilities running below the surface of the floor. The floor socket 200 is typically installed into a preexisting floor 120. A hole is drilled into the pre-existing floor that is slightly larger size of the floor socket 200. In an alternative embodiment, the floor socket 200 may be coated with an adhesive and inserted into the hole in the floor such that the top surface of the socket 200 is flush with the surface of the floor 120. The installation may take as little as 10 minutes per hole, whereas the installation of the standard removable base designs of the prior art would take more than 60 minutes per hole to install. Installation of the socket includes the following steps:
1) Tapered drive pin which would flare out the bottom of the socket 200 when hammered into a hole in the floor;
2) Threaded screw that drives into a tapered hole, thus spreading the bottom of the socket; and
3) Outside slip collar.
Often queue layouts may change over time. Additionally, a vendor may prefer to have more than one queue design installed in an existing space. The smaller diameter hole is less intrusive in those scenarios where the queue layouts may change. Even after the installation of the floor socket is complete, it is still easy to modify a layout. The ⅞ inch socket 200 mounts nearly flush to the ground. The socket 200 may include threads 208 to receive either a pillar 150 that has corresponding threads or a socket cap (
There are embodiments of the current invention that do not require a spring 308. For example, a rubber block may be used in place of a compression spring to add flexibility to the post 114. Also, a series of belleville washers may be utilized in place of a spring 308. The spring may be tensioned to constrain movement of the post 114 to no more than 10 degrees from the vertical position 180. However, the reason fora limitation of movement to no more than 10 degrees from vertical is to prevent accidental snap-back of the post. That is not a requirement of all applications. In fact, in some instances, it may be desirable that the post 114 extend to a substantially parallel position with respect to the floor.
The preferred method of assembly of the spring loaded assembly 300 comprises the steps of selecting the hex bolt 302 and one or more washers onto the hex bolt 302. Next, a washer is made of a thermoplastic material, such as delrin, is placed on the hex bolt 302. A tube 306 surrounded by the helical spring 308 are positioned on the hex bolt 302. A second thermoplastic washer 390 is placed on the hex bolt 302 as the hex bolt 302 is inserted through a hole 341 in the disc member 340.
A nylon lock nut 320 has a pin, tab or set screw 322. The nylon lock nut 320 is tightened until the spring 308 becomes loaded. In the preferred embodiment, a force is applied to the spring 308 by the nylon lock nut 320 at which time the lock nut 320 is turned 5½ turns. At this point, the disc 340 is installed on the shaft 301 such that approximately two to four inches of the hex bolt 302 extends beyond the disc 340. The cup member 310 is mounted to the bottom portion of the post 314. Alternatively, the cup member 310 could be inserted inside a hollow end of the bottom portion 316 of the post 314 and secured to the post 314. Finally, the cup member 310 could be eliminated completely, and the spring would be affixed to the inside wall of the post 314.
The spring-loaded assembly 300 includes a cup member 310. The cup member 310 is a cylindrical hollow H-cup having a flange 312 including a centered hole 311 to receive the threaded hex bolt 302. The flange 312 receives at least a portion of the threaded hex bolt 302, the washers 304 and the compression spring 308. The flange 312 of the cup member 310 has a hole 314 to receive a space screw 316. Alternatively, the flange 312 could be fixed directly to the inside wall of the post 314.
Positioned below the flange portion 312 of the cup member 310 and adjustably affixed to the hex bolt 302 is a nylon lock nut 320. The nylon lock nut 320 includes a hole for receiving a space screw 322 with lock washers. The set screw 322 may be tightened to secure the nylon lock nut 320 to the threaded hex bolt 302. The set screw 322 in the locknut 320 and the set screw 324 in the flange 312 provide for a 350 degree rotation of the post 314 upon installation of the post into the floor 340. The set screws 322 and 324 are positioned such that the two set screws 322 and 324 interfere with the rotational movement of the post 314 and hex bolt 302 upon installation of the post 314. As the finger portion 350 is threaded into the threads 208 of the socket 200, the friction between the threads on the finger portion 350 and the threads 208 of the socket 200 cause the hex bolt 302 to rotate with the set screw 322 until the set screw 322 contacts the second set screw 324. The contact between the set screws 316 and 322 causes the hex bolt 302 to rotate with the post 314, such that the finger 350 is threaded into the socket 200. Once the disc 340 contacts the floor 340, the post 314 will cease rotation due to contact between the set screws 322 and 324. Rotation of the post 314 can then be reversed to back out from the pillar socket 200 up to a 350 degree rotation at which point the set screws 322 and 324 again contact each other. The 350 degree of rotation is important because it permits the cap 130 of the post 110 to be aligned with the cap 130 of another post. The coupling 132 of one post 110 may be aligned with coupling 133 and retractable belt 131 of a second post 110 to form a queue as shown in
There is a base disc 340 that has a hole with threads 341. The disc 340 is threaded onto the threads 303 of the hex bolt. The base cap 340 serves two purposes: (1) it prevents the cup member 310 and post 314 from scratching the floor 120 and (2) it protects the inner elements of the spring-loaded assembly 300. There is a portion of the bottom of the threaded hex bolt 302 that extends beyond the disc 340. The finger 350 may be threaded 330 as shown in
The spring-loaded assembly 300 permits the post 314 to lean approximately 10 from the vertical position 180. The spring-loaded assembly 300 permits movement of the post 314 in order to absorb impact from contact with the post 314 from carts, or the like, which would impact the force onto the finger 350 engaged with the socket 160. The post 110 may be positioned on the floor 120 by aligning the pillar 316 with the opening 220 of the socket 200. The pillar 316 is inserted into the opening 220 of the socket 200 and adjusted to a vertical position 180. If the pillar 316 is threaded, the pillar 316 is aligned with the threads 208 of the socket 200. The post 314 is rotated such that the threads of the pillar 316 engage the threads 208 of the socket 200. The post 314 is rotated until the disc 340 contacts the floor 120 and the post 314 is in a vertical position 180 at 90 degrees in relation to the plane of the floor 120. The post 314 can be rotated an additional plus or minus 350 degrees from the point the disc 340 contacts the floor 120 to align the belts on the retractable member 130 or to change the queue configuration. To remove the stanchion from the socket 200, the post 314 is rotated until the threads of the finger 350 are disengaged from the threads of the socket 200.
If desired, a cap 490, may be secured to the socket 400 by engaging the threads 491 of the cap 490 with the threads 408 of the socket 400 as shown in
Although the invention has been described with reference to a particular arrangement of parts, features and the like, these are not intended to exhaust all possible arrangements or features, and indeed many other modifications and variations will be ascertainable to those of skill in the art.
