BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to footrests and particularly to folding footrests.
2. Description of the Prior Art
People who fly frequently, especially over long distances, can experience discomfort during the trip. People who are of shorter stature suffer from not being able to place their feet fully on the floor of the aircraft. Also, sitting on chairs at home, at the office, or in other locations causes problems for many people. To that end, I developed a folding footrest that is the subject of U.S. Pat. No. D693,135. While this footrest is an improvement to having dangling legs and feet, it is bulky and heavy.
BRIEF DESCRIPTION OF THE INVENTION
The instant invention is an improvement on the aforementioned footrest. It is lighter in weight and far less bulky. It assembles quickly and can be adjusted to provide several different height levels. The design has two alternative embodiments. It consists of a central member that has slots formed in it to receive tabs. Attached to one side of this member is a lower bottom member that is hinged to the central member. This member has a tab face that extends upward and is secured from below in the lower portion of the central member. Note that the tab face is hinged to the bottom member so that it can fold up against the bottom member for storage. The tab face has one or more tabs that fit into the slots on the central member. Changing which slot(s) are selected, adjusts the height of the footrest. Similarly, a top member is hinged to the other side of the central member. Like the bottom member, the top member also has a tab face but which extends downward, and is secured from above in the upper portion of the central member. Note that the upper tab face is hinged to the top member so that it can fold up against the top member for storage. The tab face has one or more tabs that fit into the slots on the central member.
In this way, the footrest can be folded relatively flat into a small square or rectangular form and then be unpacked and unfolded for use. Once the tabs are secure, the footrest is ready for use. In addition, the footrest has open ends that allow a user to carry the footrest. A handle can also be provided to assist in opening the device. Finally, snap clips (with or without magnets) can be used to secure the tab faces in place for storage.

DETAILED DESCRIPTION OF THE INVENTION
Referring now to the drawings, and particularly FIGS. 1-6, my footrest 10 is shown. In this view, the invention 10 is a first embodiment of a folding footrest shown in in the assembled position. As shown, the footrest 10 has a top section 11, a bottom section 12 and a central member 13. The top section 11 consists of a top 11a and a front piece 11b. Similarly, the bottom section 12 consists of a bottom 12a and a back piece 12b. The central member 13 is a connecting piece that has a number of slots 13a formed therein (see, FIG. 13). These slots receive tab members 11c on the front piece 11b and 12c on the back piece 12b (see, FIG. 14). In the preferred embodiment two tabs are used. Of course the number of tabs can be changed as desired.
As shown, the top section is hingably attached to one end 13b of the central member 13 and the bottom section is hingably attached to the other end 13c of the center portion (as shown e. g., in FIGS. 2, 4 and 13). Note that the top and bottom sections are reversed attached to the central member such that the top section is pulled upwardly and the bottom section is pulled downwardly to open the footrest FIG. 5 is a top view of a first embodiment of my footrest showing the top 11a. FIG. 6 is a bottom view of a first embodiment of my footrest showing the bottom 12a. Note the handle 12d in the bottom is an option.
FIGS. 7-12 are views of a second embodiment 20 of my footrest. As before, this embodiment has a top section 21, a bottom section 22 and a central member 23. The top section 21 consists of a top 21a and a front piece 21b. Similarly, the bottom section 22 consists of a bottom 22a and a back piece 22b. The central member 23 is a connecting piece that has a number of slots 23a formed therein (see, FIG. 13). These slots The present disclosure should not be construed in any limited sense other than that limited by the scope of the claims having regard to the teachings herein and the prior art being apparent with the preferred form of the invention disclosed herein and which reveals details of structure of a preferred form necessary for a better understanding of the invention and may be subject to change by skilled persons within the scope of the invention without departing from the concept thereof. Receive tab members 21c on the front piece 21b and 22c on the back piece 22b. Note that FIGS. 13-17 apply to both embodiments.
The only real difference between these embodiments is the final shape of the assembled footrest. As shown in FIG. 2, the first embodiment is generally box-like, with substantially vertical front and back pieces. The second embodiment has angled front and back pieces as shown, e. g., FIG. 8.
FIG. 13 is a perspective view of the central member of my footrest. In both embodiments, the central member 13 or 23 acts as a bridge to connect the top section with the bottom section of the footrest. As noted above, it has a number of slots to receive the tab on the front and rear pieces. Note that the connection points between the central member 13 or 23 is hingably attached to the top and the bottom at their respective attachment points e. g., 13b and 13c and 23b and 23c respectively. This allows the device easily to be folded and unfolded. In the case of the second embodiment, these hinges are shown as 23b and 23c as shown in FIG. 9, for example.
Optional magnets snaps, clips or hook and loop type fastener dots 14, 15 and 16 (see FIGS. 1, 3, and 13) can be added to secure the footrest when folded.
FIG. 14 is a detail showing a recess 11e or 21e cut into the top panel for receiving the front and back flaps as described below (see also FIG. 15 when the footrest is folded (the bottom 12 is shown here)).
A unique feature of this footrest is its ability to fold generally flat. To do this, as mentioned above, the insides of the top and bottom have recess 11e or 21e and 12e or 22e, that are formed to receive the front and back pieces. Thus, as shown in FIG. 15, a back piece, either 12b or 22b is folded into the recess, either 12e or 22e (see FIG. 14 to see the recess), flat, for storage. The same applies to the front piece in both embodiments. Note that the connection between the top 11a and the front piece 11b forms a hinge 11f or 21f (FIG. 14) about which the front piece can be folded and unfolded. Similarly, the edge between the bottom 12a and the back piece 12b forms a hinge 12f or 22f for those parts to fold.
FIG. 16 shows the footrest partially folded for storage. In this view the bottom has been folded and the front piece is shown being folded into the top. FIG. 17 shows the footrest folded for storage. In this view, the folded footrest is shown with a fairly flat profile, that makes it easy to store and carry for use.
To fold the footrest for storage, first the front piece 11b in the first embodiment, is raised from the center portion 13 and is folded up into the recess 11e on the underside of the top 11a. The back piece 12b is raised from the center section and folded into the recess 12e against the inside of the bottom 12a. See, FIGS. 14 and 15. Then the top section 11 is folded against the top of the center section 13 and the bottom section 12 is folded against the center section 13. At this point, the footrest is folded, as shown in FIG. 17. In this way, the footrest can be carried to wherever it is needed. The footrest can then be quickly opened and the front and back portions can be secured in the central member. The device is then ready for use. Note, the different slots in the central member can be used to adjust the height of the footrest within limits. Again, the same steps apply to the second embodiment.
FIGS. 18-25 show the preferred embodiment of the invention 30. In the preferred embodiment, the central member 35 has a pair of notches 35a on each end as shown, to receive the front and back pieces 33 and 34. Unlike the center portion of the previous embodiments, which have a set of notches that allows the height of the foot rest to be adjusted, this central member has two openings 36 and 37 that are shaped to accept the front and back ends of the footrest, as discussed below. In this way, the foot rest can be folded flatter than the previous embodiments. FIG. 18 is a perspective view of the preferred embodiment shown opened for assembly. This view shows the device 30 in its open configuration. As noted above, this embodiment has a central member 35 has a pair of slots 35a on each end as shown, to receive the front and back pieces 33 and 34. Unlike the center portion of the previous embodiments, which have a set of slots that allows the height of the foot rest to be adjusted, this center portion has two openings 36 and 37 that are shaped to accept the front and back ends of the footrest. As before a top 31 and a bottom 32 are attached to the central member 35. Both the front and back pieces 33 and 34 as well as the top and bottom 31 and 32 are attached by living hinges 38, which are represented as shown, although the hinges are integral to the pieces—i. e., the front piece 33 is hinged to the top 31 by a thin member formed between them. In this way, the front and back pieces 33 and 34 are hinged to the top and bottom 31 and 32 and the top and bottom 31 and 32 are hinged to the central member 35.
FIGS. 19 and 20 show top and bottom views, respectively, of the preferred embodiment shown folded for storage.
FIG. 21 is a left side view of the preferred embodiment shown assembled. In this figure, note how the ends fit into the center portion in a similar manner to the other embodiments.
FIG. 22 is a front view of the preferred embodiment shown assembled. In this figure note how the tabs 33a and 33b fit into the center section 35.
FIG. 23 is a rear view of the preferred embodiment shown assembled. In this figure note how the tabs 34a and 34b fit into the central member 35. FIG. 24 is a top front perspective view of the preferred embodiment shown assembled. Finally, FIG. 25 is a right side view of the preferred embodiment shown assembled.
The present disclosure should not be construed in any limited sense other than that limited by the scope of the claims having regard to the teachings herein and the prior art being apparent with the preferred form of the invention disclosed herein and which reveals details of structure of a preferred form necessary for a better understanding of the invention and may be subject to change by skilled persons within the scope of the invention without departing from the concept thereof.
