Description

CHAIR STORAGE UNIT DESCRIPTION OF THE INVENTION The present invention relates to permanent, semi-permanent, portable and / or folding seat storage containers that are designed to fit and fold to the bottom of chairs. Folding chairs have long been the standard for most forms of massive seating. Whether in a theater, a sporting event, a stage event or a reading room, the spring-loaded folding seats where the base / seat cushion is pushed up when the participant is not seated have become the standard Worldwide. That popularity is logical: the folding seats allow to locate a large number of people in relatively narrow spaces and still have enough comfort to keep people seated for long periods. A disadvantage of folding seats is that they do not allow easy storage of various personal items, programs, etc. Instead, such items often end up on the sides, corridors, or require the use of a remote locker. Such alternatives obviously add inconvenience and cost. In addition, existing designs do not solve the inherent danger of providing storage that easily affects the content. For example, in stationary chairs, such as those commonly used in schools, a basket can be provided under the legs of the chair to store books etc. Such an arrangement in a folding chair makes it inoperable to the chair or very inconvenient from a storage point of view. To overcome such disadvantages, attempts have been made for a long time to provide a storage alternative. In fact, a number of those intended solutions have been patented. For example, U.S. Patent No. 5,573,288 to Raffensperger discloses a portable seat cushion and storage container that can be attached to a folding chair. VELCRO® hook and loop fasteners are used to easily attach the cushion storage member to the seat. A disadvantage of the Raffensperger patent is that it requires user installation and is not used for permanent storage. Furthermore, to use this arrangement a very rough operation is required where the user has to wrap the container around the chair, hold the storage unit towards the bottom of the chair and then reconnect the cushion to the storage container from the back of the seat. In a situation of massive seats, that amount of work can easily cause crowds.

Another much simpler arrangement is described in the US Patent Number. 5,490,712 for Drelick. The Drelick patent describes a storage container that can be closed for removable attachment to the bottom of a stadium seat. The Drelick container is suspended under the seat when in use and held in the seat by means of a strip (very similar to a strip for a paperback). However, Drelick provides a construction that must be removed from the stadium by the user. If you forget, valuable items can be left behind. In addition, the container in the Drelick patent is effectively formed as a box that does not serve when objects larger than the dimensions of the box are placed in the container. Finally, there is no user ability to see inside the Drelick storage compartment. Therefore, articles can easily be forgotten. Another patent of little interest is French Patent Number 1,829,486 to Kimbrig, et al. Kimbrig emerges to describe pivotal theater seating combined with d-e cloth containers placed under those seats for storing items. In Kimbrig, a rope pattern is attached to the seat by means of a metal structure. However, the unit is not portable or removable by a user or a stadium attendant.

Finally, there are a number of storage devices described in U.S. Patent Nos. 4,854,637, 4,521,637, 4,131,313, 3,151,909 and 2,865,433 which are designed to be foldable and act as a seat and storage device. Most of these devices, however, provide covers or bags that are located in front of the seat. Therefore, these bags can cause some discomfort of the seat, can be annoying for the use and can result in articles that fall from the bags if the person using the seat moves his legs in the wrong way. Finally, in addition to the deficiencies described above, there are other varied problems with respect to storage under the seat that do not comply with the references described above. First, there is a lack in the technique of storage containers under the seat that can be fixed permanently to the bottom and that are still easily removable. Additionally, storage devices are not available under the seat that (1) are easily expandable depending on the amount of material provided therein; (2) can be installed and permanently or semi-permanently, quickly and inexpensively; (3) flexible materials are designed, thereby making the storage units applicable to any type of surface material such as a rough surface as well as a contour, whether flat, curved or angular; (4) are transparent to provide the user with access to information such as advertising and promotions; (5) they are easily cleaned by a hose without requiring any additional operation from the stadium staff; (6) is usable despite the inclement weather and (7) includes a bag that is transparent or has a window and that is releasable or fixed permanently to the storage container such a bag allowing the display of the materials contained in the same, such as promotions, programs or samples etc. In addition, the flexible material can adhere to the surface through a variety of fastening means, making installation inexpensive and easy to engrave. Finally, there is a need in the art for a seat storage container that can be made inexpensively and can also allow printing or engraving thereon by advertisers, stadium or theater authorities or others. In view of the foregoing, there is a need in the art for an invention that satisfies one or more of the above-identified objects. It is a main object of the invention to provide an article storage device that allows the user to transport the device, fix it to the underside of a seat, expand the device in use or contract the device for transport, see through the device such items as advertising and remove the device, at the option of the user and / or the option of the owner. It is a further object of the invention to provide a universally applicable under-the-seat storage device that is flexibly foldable to the bottom of a seat having any type of contour and that can be attached to the seat through hook and loop fasteners , such as VELCRO®, screws, bolts, fastening magnets, adhesives, wing nuts, bolts and coupling hole slots or other appropriate fastening devices or substances. Furthermore, it is an object of the invention to provide a storage device under the seat where permanent installation is an option or serai-permanent installation is another option, or the completely removable installation is also an option. It is another object of the device to provide a mounting unit for a storage device under the seat whereby the storage device is held in the seat by any number and type of fastening substances or holding devices, such as magnets that They provide metal-to-metal connection.

It is a further object of the invention to provide a storage device under the seat that is expandable, such as an accordion-shaped container and that can be differentially expanded so that an inner portion of the expandable material (i.e. the nearest to the back of the seat) expand more than a front portion of the cover (closest to the front of the seat), so that when the seat is vertical, the step in front of the chair is not restricted. It is a further object of the invention to provide a storage unit under the seat which is made of transparent plastic having multiple openings therein to allow drainage when washing or during inclement weather, etc. It is another object of the invention to provide a storage unit under the seat made from the material, such as fabric, and having similar or inferior plastic or tops to which the material is connected along the sides allowing this so that the storage unit under the seat is washed and allowed to be breathable and still have sufficient structural strength to hold heavy objects. A further object of the invention provides a storage device under the seat made entirely of spandex or other material having similar properties having a plastic upper part attached thereto to allow Spandex, etc. of the sheath will expand differentially towards the back. It is a further object of the invention to provide a seat storage unit in which part or all of the material is an insulating material so that the temperatures of the articles placed in the storage unit can be maintained when they are stored. Said in a few words, this and other objects of the invention are achieved by means of a storage device under the seat made of an expandable material for example comprising a configuration in the form of accordion, Spandex or other expandable material. The material has an upper portion having a plurality of hook and loop fasteners, fasteners, magnets, screws, bolts, adhesives, wing nut, etc. attached thereto, three side portions having folded accordion surfaces and a front portion having an articulated flange opening to a lower portion and a hook and loop fastener (or other fastening material) in the center thereof. A plurality of hook and loop fastener strips are also located at the bottom of a collapsible seat so that the cover can be easily and / or detachably joined from the bottom of the chair by pushing the hook and loop fastener strips or pulling them. The storage case may also include a smaller central container or attached to the storage case. The smallest container can be made of a clear or translucent plastic that can be attached separately to the storage case by means of hook and loop fasteners, rubber cement, fasteners, magnets, bolts, screws, wing nut etc. . or they can slip inside the storage device. Finally, the sleeve can be completely portable and disposable, and made of inexpensive material such as Tyvek. These and other objects and advantages of the invention will now be described with respect to the drawings appended hereto as well as the detailed description of the invention and the claims.

Figure 9 is a perspective view of a second embodiment of the container for the present invention. Figure 10 is a perspective view of a third embodiment of a container for the present invention. Figure 11 is a perspective view of a fourth embodiment of a container for the present invention; and Figure 12 is a perspective view of a fifth embodiment of a container for the present invention. Referring to the diagram where similar reference numbers are. Refer to similar objects, Figure 1 is a perspective diagram of a first embodiment of the invention mounted on a stadium chair 10. As shown, the chair 10 includes standard components that include a backrest portion 32, arms 34 legs 36 and a seat base 12. The seat portion is hinged up and down so that when an individual wishes to use the chair, the user can push the seat 12 of the chair down and it is known that the seat remains substantially horizontal in relation to the stadium floor. The base of the seat may for example include a cushion portion 12 and a structure portion 16. However, any conventional type of stadium or auditorium seating may be used. Therefore, the base portion of the seat may also not have a cushion, have a substantial cushion or a structure made of any number of materials including plastic, wood and / or metal. The seat structure and a lower portion 14 which, when the seat is not occupied, can articulate in a substantially vertical position. As illustrated in Figure 1, the first embodiment of the present invention comprises a device 18 that includes a storage compartment (not shown) that is designed to be attached to the lower surface of the seat 15. The storage device 18 is attached to the seat by means of a plurality of connection members 26A-26D. The connecting members 26A-26B are capable of making the storage device 18 easily removable / foldable to the seat. Alternatively, members 26A-26B can be permanent connection members. The storage device 18 also includes an enclosure 20 with closure means 30 as well as a connection cover device 22 having a window portion 24 to provide a separable cover capable of storing the appropriate material, such as advertisements, flyers, sheets of results, scripts, team logos, colors or messages, etc. As shown, the storage member 18 is designed to provide storage under the seat for stadium / theater type seating. The storage member 18 is designed so that it can be attached only to the lower part of the seat so as not to deteriorate or disturb the comfort of the user, as well as to provide any type of obstruction for those who must pass in front of the seat. The storage unit is shown in greater detail with respect to Figure 2. Specifically, the storage unit 18, as shown in Figure 2 is completely made of a flexible plastic material. However, the storage unit can comprise any known material that has a sufficient degree of flexibility and transparency. In addition, the material can be insulator by nature so that the temperature of the material of the storage device is maintained at a desired level despite weather or construction conditions. The plastic material or the like may be transparent to provide the user with an indication that the sheath contains articles therein. As a consequence, the user is less likely to forget what has been stored under his seat and for security purposes, security personnel can easily see any potentially damaging items under the chairs. However, if promotional material is contained in the cover, its transparency obviously promotes access to that information. It should be noted, for example, that the storage device 18 can be made of inexpensive disposable material such as Tyvek, or can be releasably or flexibly fastened not only to the bottom of a seat, but to the back of the seat, a wall, column, seat side or any other desired surface. In addition to the plastic material the storage unit 18 includes an accordion-shaped side portion 202. The accordion shape is differentially expandable so that such as the front portion of the cover 20 of the storage container will expand to the distance 207 as shown in FIG. indicated by the arrows. On the other hand, towards the rear portion 208 of the storage container, the expansion will be at a much greater distance 205. The importance of this differential expansion of the accordion-shaped container is illustrated in Figure 2b. As shown in that diagram, the seat 12 is in an unoccupied substantially vertical position. In that position, the storage container 18 is differentially expandable so that the lower portion 204 expands less than the upper portion 206. The closure means such as the hook and loop fasteners, adhesive, pressurized or any other device of Appropriate reclosable fastener 212 is located in the center of the accordion-shaped container. In use, these fastening means can be used to close the container when it is empty by pressing the center of that container. As a result, a distended container can be compressed back to a position where it remains relatively flush with the lower surface of the seat. As a consequence, due to the vertical seat angle, the storage sleeve 18 does not impede passage. In addition, the flexible configuration ensures that the maximum amount of storage space is maintained since the larger objects can be stored towards the rear portion 208 of the container 18. A further object of the container 18 is that its rear portion 208 include at least an opening along the lower right and / or left rear corners 214 and the upper right and / or left rear corners 216 (the left sides are not illustrated) to provide draining of the container 18 when that container 18 is flooded. As a result, permanently or semi-permanently installed devices can be cleaned by a hose, adjusted in a closed position, and still continue to drain the water due to the vertical position of the seat that induces flow to the rear corners 214, 216 Such drainage also has obvious advantages if the devices are exposed to rain, snow, spills, etc. Referring to Figure 2a, storage container dl8 is attached to the lower portion of chair 14 by means of a plurality of fastening means 26A-26D. The securing means may consist of a number of different types of device. For example, each can comprise an anchor bolt (not shown) threaded through a properly dimensioned washer. The anchor bolts are of sufficient height so that when they are inserted into the lower portion of the chair 14 they do not impact the user through the seating or the seat surface of the chair. Alternatively, the clamping units may comprise double-sided mounting tape or mounting frames. Mounting frames, for example, can be those sold by Minnesota Mining and Manufacturing. Another material for the fastening means may be the hook and loop fasteners. However, if the hook and loop fasteners are used, a corresponding coupling piece would need to be attached to the lower portion 14 of the seat 10. Finally, if the metal seat structures and the lower seat portions 14 are used, then the means The fastening elements can comprise a plurality of magnets that can be attached to the storage device 18. Magnets of sufficient strength are highly desirable for a metal frame chair as they can be attached very easily to the bottom of the chair and do not require alignment to a lower part of the chair in particular. For example, the magnet arrangement would have an advantage over the hook and loop fastener arrangement that requires the alignment of the fasteners. Referring now to Figure 3, a perspective diagram of cover container 22 is shown. The container or fastener 22 can be formed from a folded arrangement similar to a standard mail envelope or for that purpose from any other suitable transparent cover for the material. However, the container 22 can be made of completely transparent or translucent plastic to ensure long loop life. The container 22 is attached to the storage container 18 by means of four securing means 302A-D. The container 22 also includes fastening means 34 which may consist of a hook or loop fastener or a suitable metal clamping and / or plastic clamping arrangement or magnets, fasteners, screws, bolts, wing nuts, adhesive or other device or substance of appropriate support. Finally, container 22 must be easy to close in use. The container 22 may include the window portion 24. For example, if the container 22 is of a translucent or solid material that does not allow the user to easily determine what is contained therein. The present window 24 can be used as shown in the drawings to show the appropriate portions of what is contained in the container 22. The container 22, in use can be an article that is designed to be easily attached by means of fasteners 302A-D to the storage container 18. An example of its application would be in a situation such as a flyer or advertising sheet in a sporting event. For example, the promotional material can be placed in the transparent container 22 and delivered to the users in the game or mounted on the underside of the seats before the game. Therefore, when the user goes to his particular seat a piece of promotional material is visible to the user before he places his seat down. Therefore, advertising is located at the point where the user is most likely to see and use it. Since the container 22 can be mounted in the storage container 18 by means of the detachable assembly 302A-D, such as hook and loop fasteners or snaps or a double tape or adhesive, magnets, etc., the container 22 can being easily foldable / detachable from the storage container 18, and / or having the ability to slide over the storage container 18 (as shown in Figure 3b), and / or having a slot or opening for placing the advertising materials / promotional or similar in the storage container 18. Referring now to Figure 4 and Figure 5, an alternative embodiment for the fastening means for connecting the storage container 18 to the lower portion 14 of the chair 10 is shown. As shown in Figure 4, a number of fasteners 400 is designed to hold the storage container 18. , at suitable points, to the lower portion of the chair 14. As shown, the fastener 400 is designed to be inserted through a slot 402 in the side portion 202 of the container 18. An inner portion 404 secured to the interior of the container 18. An upper collapsible portion 406, on the other hand, is designed to hold onto the side of the chair structure 16 or the lower portion 14. The distance of the front portion 414 of the main portion 408 of the fastener is greater than the distance of the lower folded portion 409 from the main portion of the fastener 408. (see Figure 5). As a result, the upper portion 406 of the fastener 400 is adapted to adjust the structure of different sizes 16 or lower portions 14. It should be noted that the slot 402 can be reinforced by an appropriate washer or reinforcing material. Referring now to Figure 6, an alternative embodiment for a closure of the container 18 is shown. A tab 600 is provided with a strip 604. A portion of the bottom side of the tab 600 has a hook and loop fastener tab 602 or metal / plastic snap, magnetic adhesive, etc., located therein. The hook and loop fastener tab 602 is positioned such that it can contact a tongue of equivalent size 608 located on the underside of the upper portion 610 of the container 18. The hook and loop fastener tab 608 pulls the tab toward above and on the material contained within the storage container 18. A third embodiment of the closure is shown in Figure 7. In that Figure, the hook and loop fastener material or the metal / plastic snap, magnetic adhesive, etc. 702 is located across the entire lower flange 700 and the upper flange 704 is positioned along the upper portion 610 of the cover 18. The upper flange 704 contains a hook and loop fastener strip complementary or snap fastener. metallic / plastic pressure, magnet, adhesive, etc., 710 extending substantially through the upper flange 704. As a consequence, the closing of the flange occurs by attaching the fastener 702 to the fastener 710 so that a seal through the entire closure is achieved. Finally, Figure 8 illustrates a third embodiment of the closure. In this embodiment a lower pad or metal / plastic pressure fastener, magnet, adhesive, etc., 810 is designed to butt against an upper pad 812 so that when the user presses the two surfaces together they adhere to facilitate closure of the container Storage 18. Referring now to Figure 9, a second container mode 900 is shown. This embodiment 900 comprises a container having an upper portion 902, a lower portion 904, side portions 906 and 908, a rear portion 912, a front portion 914 and a closure 910. The upper and lower portions 902, 904 are made of a semi-rigid plastic or similar materials. The side portions 906, 908 on the other hand, comprise a flexible mesh fabric. Finally the closure 910 is made of a flexible plastic that is adapted to move up and down. The importance of the sides of mesh fabric 906, 908 is that it provides breathability and drainage in case the container 902 is washed. The cloth sides also allow the container to be expanded flexibly to accommodate a large load. In addition, the fabric sides 906, 908 are formed such that their rear portions 912 are wider than the front portions 914. Thus, the same advantages achieved by the sides 202 in the first embodiment (ie allow the passage without interference). when the seat is in the vertical position and the container is full) are achieved. Figure 10 illustrates a third embodiment 1002 of the container. In this embodiment, which is similar to Figure 9, the side portions 1006 and 1008 are made of a net type material instead of a cloth mesh. The network provides similar advantages to the fabric mesh: breathability, expandability and flexibility. However, an additional advantage is that the user can see inside the container from the sides which obviously provides better visibility. Figure 11 represents a fourth embodiment of the storage container. In this embodiment, an upper portion 102 is made of a semi-rigid plastic material. Secured to the top is a body portion 1104. The body portion 1104 may be secured to the upper portion of semi-rigid plastic by means of heat fastening or other appropriate methods to form a permanent bond. The material of the body portion 1104 is an expandable water resistant type fabric material, such as Lycra® or Spandex®. The body portion includes an opening 1106 that allows the user to place items within the container. Because the opening is made from the same material as the body, the opening can be widened to accommodate larger objects and then automatically retracted to its smaller size. Figure 12 represents a fifth final embodiment of the represented invention. Specifically, Figure 12 illustrates a storage container under the seat 1202 made of a plurality of rigid materials including wood, plastic, metal. The container 1202 is designed to be connected to the lower part of a seat through connection anchors 1204A-D. The appropriate anchors for a wooden or metallic box may require the use of an anchor bolt, as previously described with respect to the first embodiment. The storage container includes a door portion 1206 that is operated by means of a key operated key 1210 located in a central portion of the door. An identification plate can be added and it can be located under the lock. The plate can contain the name of the user or the company, the seat number or any other appropriate identifier.
