Description

Device to Aid Persons Rising frotn a Seated Position Field of tlle Invention 'hhis invention relates to devices that assist people as tliey rise up from.
ol- sit down into, a seated position, and, more particularly, to a reversible aid for such use which can be placed on either side of a chair.

Backs,round of the Invention Many persons have difticulty rising from, or sitting down into a seated position.
Tbis nlight be because of an intirmity due to injury, illness, advanced age, or some otlier debilitation. This difficulty is of special concern wben padded chairs and eouches are used as seating devices, as the individual may sit deeply in the cushioning, and tlius aggravating any difticulty in getting up. Devices that utilize a handle to pernlit the seateci person to grab hold of and pull on while rising are well known. In some cases, these devlCCs are nornlally not ConneCt'ed to any partlClllar piece Of ftll'1lItLIrC
and, t1lUs. nlay he enlployed anywhere the individual Inay be seated.
Typical devices utilize a pair of bars which are positioned in front of the person as he rises. These devices normally must be positioned under and in front of the chair and typically will block the view of the user or are obtrusive. Known prior art includes U.S. Pat. Nos. 3553746; 4844107: 4922560; 4843661; 3591874; 3739793; 4941495:
and I., S P 001 3695609. These devices can generally be described as "chair assist" devices.
Additionally, in US Patent No. 5295498, Van Metei- et al. provide a chair assist having a brace that would rest Lulder the legs of a chair. couch, sofa or the like. and an upri(Tht arm that could be utilized by a user to assist in pulling theniselves upright. In the enibodiment shown by Van Meter, the arm is essentially a straight rod with an upright liandle, but a recent development has artns with a curved configuration but Which project outward in a plane which is parallel to a longitudinal axis of the base, and which is thus parallel to the plane of the side of the chair, couch, sofa or the like.

While these devices have proven to be useful, additional development is desired in ordei- to provide an improved benefit to persons requiring these features.

In particular. it would be desirable to provide a cllair assist device, or more generally, a transferring tool device, that would be less intrusive when not in use.
Additionally, it would be desirable to provide a chair assist that was adjustable to better fit a variety of cliairs, couclies, sofas or the like. Further, it would be desirable to provide a chair assist wherein a handle can be provided that would better assist the user, while not being a impedinient to use by, or an obstruction to, the user.

Still further. the weight of the seat is the primary mechanism to hold the pi-ior art ehaii- assists in place. This can be a problem if the chair is light in weight, andJor a relatively large force is applied to the chair assist. As a result, the chair assist of the prior art can move and possibly upset the balance of the user. This could occur as the user was sitting down in the seat, or was rising fi-oni the seat. As such, it would be desirable to provide a chair assist that could be niore securely fastened to the chaii-, couch. sofa or the like in order to prevent inadvertent movement of the assist with respect to the seat.
To overconie these difficulties, in accordance witli the pi-esent invention, it would tllerefore be advantageous to provide a chair assist wherein a folding handle is pi-ovided that extends partially aci-oss the user that can be used to facilitate rising from a chair, which handle can be moved out of the way when the user is being seated. or while the user is seated.

Further, it would be advantageous to provide a chair assist wlierein a support arm was either foldable to be removed out of the way when not needed, and/or which was adjustable, or preferably telescopic in nattu-e, so that it could be fitted to a particular chair, couch, sofa o-- the like (hereinafter collectively ternled as a 'seat").

Yet further, it would be advantageous to provide a chair assist wherein the base of the cliair assist can be even nlore securely fastened to the seat.

Suninlary of the Invention The advantages set out hereinabove, as well as other objects and goals inherent thereto, are at least partially or fully provided by the device of the present invention, as set out herein below.
In one aspect. therefore, the present invention provides a device to aid persons rising fi-om, or sitting down into, a seated position in a seat, comprlslng:

an elongated, generally horizontal, support base which base is adapted to be positioned under the legs of said seat;
an upwardly extending sleeve attached at one end to said base, and having an opening at an opposite end for receiving an elongated vertically orientated support arm;
an elongated support arnl extending upwardly fi-om said sleeve and having a first end adapted to fit witliin said opening in said sleeve and a second end extending, in use, to a position above said seat; and a nlovable handle extending from said second end of said support arm, wherein said movable liandle is nioveable from a storage position to an active position so that when said moveable handle is in said active position, said handle extends at least partially across the front of said seat.

Detailed Description of the Pi-eferred Embodiments For the purposes of the present description, the term "seat" is used. As previously described, the pi-esent application is therefore primarily directed to a device that is of use with a chair liaving one of more legs on its side. However, the skilled artisan will be aware that the device may used in a wide val-iety of seats including, for example. chairs, couches, sofas, lounges, chesterfields, benches, or the like. Accordingly.
while the pi-esent application will hereinafter be desci-ibed with particular refel-ence to a"seat'", the skilled artisan would be aware that the device of the present application is useful with a wide variety of different types of seats.

Tlie novel features whicll are believed to be characteristic of tbe present invention, as to its structure, organization, use and method of operation, togetller with fui-tliel- objectives and advantages tliereof, will be better understood from the followin"
drawings in which a pi-esently pi-efei-i-ed elnbodiment of the invention will now be illustrated by way of example only. In the drawings, like reference numerals depict like elenlents.

It is expressly undelstood, however, that the drawings are for the purpose of illustration and desci-iption only and are not intended as a definition of the limits of tlie Inventloll.

Referrini, to Figure 1 a device to aid pei-sons rising fi-om, oi- sit down into a

-4-seatcd position 10 is sllown. Device 10 may be fabricated li=om any suitable material that can provide the structural integrity necessary fOn- use. This can include, without limitation, materials such as iron, steel, aluminum, wood, plastics or the like, or conlbinations thereof. Preferably, however, the device is nlade essentially entirely ol' steel.

Device 10 can be painted or have other sin-face treatnlents in order to provide sonie aesthetic ifeatures, such as blending in to the design of the room wllere it is used.
Altei-natively or additionally, it can be painted to include safety features such as a brightly coloured sections which will be clearly visible.
Device 10 has a base unit 12 which is preferably provided with structural end rails 14 and a side rail 16 on one side. The opposite side of base unit 12 preferably does not have a side rail in order to facilitate sliding the device undei- the legs of a seat (not shown).

Base 12 of device 10 is essentially flat and horizontal and intended to be fitted under at least one leg, and preferably at least 2 legs of a seat (not sllown).
Base 12 has a length of approximately I meter and is therefore adapted to be fitted under most seats.
An extension plate, not shown, can be fitted to base 12 if additional length is reduired to fit Luider the legs of a seat.

The bottom of base 12 can be a flat surface which would be suitable for restin(T
on a carpet or the like. Preferably, however, the base can additionally comprise any of a number of non-slip or protective devices, such as foani rubber or neoprene mats l'). pads or coatings, to allow the base to rest on a tlooi- and mininlize the possibility of slippinOof the base unit, and/or protect the floor surface.

Attaclied to side rail 16 are two seat leg locking devices 18 whicll are slidable on side rail 16 in agroove 19 formed in locking device 18. Locking devices 18 prefcrably include a V-shaped notch 20, which is adapted to receive a the front and rear legs of a seat. Notches 20 can be any suitable sliape, but a V-shaped clamp has been found to be of use in the practice of the present invention. In use, base 12 is slid under the legs of the

-5-seat until the seat legs are aligned with notches 20 in locking device 18.
Lockin", devices 18 are then moved by sliding along side rail 16 until the seat legs are positioned within notches 20. Locking devices 18 are then fixed into position by tightening bolts 22 Vvhich press against side rail 16 to hold the locking device in position.

Alternatively, one locking device 18 might be permanently altixed to base 12.
with a second locking device being capable of moving so that it can be positioned against a second scat leg once the permanent locking device was in position agaiiist a f-irst seat leg. Preferably, however, at least I leg locking device is provided. and more preferably, at least 2 leg locking devices are provided. Still fiirthei-, it is prcferred that at least one leg locking device be moveable in order to provide adjustability for diffei-ences in the distances between seat legs. In the most preferred enlbodiment, the device has two moveable leg locking devices.

In the prior art, the weight of the seat holds device 10 in place by having the leos rest on the base unit. In the present invention, however, base unit 12 is also prevented from movitig, as it is being used by person rising from the seat, since locking devices 18 pi-event sideways or back and forth movenient of device 10. As such. device 10 is more lirmly held in a proper position than prior art devices.

Further. non-slip iiiats 17 made of; foi- example, neoprene or rLibbei-, can bc litted to an upper surface of base 16 in the areas where the legs of the seat would commonlv rest, in order to further reduce the risk of havina the seat slide uniutetitionally.

Interior 24 and exterior 26 L-shaped attachment plates are used to hold sleeve in piace using bolts 28. In the embodiment sllown in Figure 1. interior plate 24 and exterior plate 26 are bolted to side rail 16, by bolts 28, and thus are firmly connected to base 12. Sleeve 30 might also be held to base unit 12 by welding. or sonie othei- method.

However, as shown in the figures, the use of attachment plates 24 and 26, or some other releasable attaclullent means. allows sleeve 30 to be temporarily removed from base uuit 12 for transportation or storage.
Attachment plates 24 and 26 could be any of a variety of shapes. However.

-6-preferably these plates are L-shaped so as to be able to assist in preventing inadvertent tilting of device 10 in a sideways direction when weight is placed on a support arm 32.
This is particularly true with exterior L-sllaped attachment plate 26 since it reduces the possibility of device 10 tipping over in a direction away from base 12.

As a result, device 10 is very stable in that the leg locking devices prevent the device from moving sideways, or back and fortll, while the L-shaped attacliment plates prevent tipping of the device to the side. The length of base 12, with the weight of the seat, acts to prevent device 10 fronl tipping to the fi=ont or back.

Sleeve 30 is welded to sleeve attachment plates 27 and 29 at a desired angle.

Plates 27 and 29 are then bolted to, for exanlple, L-shaped attaclvnent plates 24 and 26 using bolts 28, and thus, effectively connect sleeve 30 to side rail 16.

Sleeve 30 is preferably a hollow tube which extends upwards from base 12 at a desired sleeve angle. In a alternative design, shown in Fi_gure 6, sleeve 30A
may be bolted to attachment plates 24A and 26A using one of a number of additional bolt holes 31. One end of sleeve 30A is bolted using bolt 33 so that sleeve 30A is pivotable about bolt 33. Sleeve 30A is fixed in position with a second bolt which migbt be inserted into any one of bolt holes 31. This allows the sleeve angle of sleeve 30A to be adiusted with respect to base 12. This miglit also include a bolt hole 35 that allows sleeve 30A to be nioved to a storage position where sleeve 30A would be essentially parallel to base 12.

However, most commonly, sleeve 30 is fixed into position, as shown in FigLu=e 1.
A support arm 32 is fitted within sleeve 30. The inner diameter of sleeve 30 is sLifficiently large so as to receive one end of support arm 32, and a C-clip 34 fixed to the side of arm 32. In use, arm 30 can be essentially fLilly inserted into sleeve 30 so as to provide a lowered arin height. Arm 32 can also be raised so that clip 34 fits over thc cnd of sleeve 30, and tllus holds arm 32 at a raised height. Arm 32 can be titted with a plurality of clips. or other temporary attaclnnent means, in order to adjust the heiglit of arm 32. 'I'his can be used to adjust the heigllt of the arin depending on the height of the seat, or the height of the user, for example, or also allows arm 32 to be lowered in order

-7-I>SP 001 to lacllltate storage or trarlsportatlon.

Arni 32 might also be preferably removed completely from sleeve 30 for stora"e or transportation. Also, although sleeve 30 and arm 32 are shown as being square tubes, any suitable shape of sleeve andlor arm might be used.

Sleeve 30 is preferably of a length which is approximately equal to the length of support arni 32. However, the relative lengths of slecve 30 and support arnl 32 can varv significantly. Together, however, sleeve 30 and support arm 32 prefei-ably have a conibined length, in use, of between 0.5 meters and 1 meter. Sleeve 30 preferably has a minimum length of at least 10% of the conibined useable length of sleeve 30 plus arm 32, and more preferably, has a ulinimum length of at least 30% of the combined length. At the opposite end of arni 32, a handle portion 40 is provided.
Preferably, handle portion 40 is movable from an active position, as shown in Figure 5A to a stored position, as shown in Figure 5B. In the stored position, handle portion 40 does not interfere with a user when the user is seated in the seat. While handle 40 might be moved from one position to the other by a variety of means, including, slidinb the liandle section, or by providing a telescopic handle section, preferably the liandle is rotated into the storage and/or active position, when required, by rotating handle 40 arocuid bolt 44.
When not required, the handle is pi-eferably rotated at least 75, and more preferably 90 degrees, to a position which preferably is at least co-linear with the support arm. More preferably, handle 40 may be rotated fiirther to a position that is 180 degrees to its position when in use. Even niore preferably, liandle portion 40 is rotated 270 degrees to a position that rests along side arnl 32, as sllown in Figtu-e 513. The direction of movement of handle portion 40 is shown by arrows A and B in Figures 5A and 5B.
Other handle storage arrangements are also possible, but preferably the llandle is rotatable to a storage position that is between 45 and 300 degrees to its active position, and niore preferably, is rotatable to a position which is between 90 and 270 degrees to its active position.
Handle portion 40 is preferably fitted to arm 32 using handle attachnient plates

-8-46 which are connected to arm 32. Handle attachment plates 46 are preferably weldcd to arm 32 although otlier attachnlent means might be used. Bolt 44 extends through plates 46 and handle 40 and thus connects handle 40 to arm 32. Handle portion 40 is fi-ee to rotate aroluid bolt 44, and thus, can be moved fronl its stored position to its active position. As such, bolt 44 acts as an axis of rotation for handle 40. which axis of rotation is located at the end of support arm 32.

Handle 40 is prevented from nloving past the active o-- storabe positions since it will move to a position where a portion of the handle will rest on, or be adjacent to arm 32, i-espectively.

Handle 40 nlay include a grip section 42, such as, for exaniple, a rubberized or foam grip 44 to cover at least part of the handle, in order to better enable a person seated in the seat to grasp the handle.

Plates 46 niiglit also be fitted with a rubberized oi- foam grip section 48, wliich a user can also use as a temporaiy rest while standing neai- device 10.

It is to be noted that a primary advantage of the rotatable handle is that liandle 40 can be rotated into an active position w11en required to assist the user in rising from the seat, or when sitting down into the seat. In the active position, handle 40 has a length of preferably between 10 and 30 cni, and thus preferably only partially extends in front of the user. This allows the user to more easily grasp the handle than prior art devices. This position also assists in pulling the user straight forward out of the seat.
However, liandle 40 preferably does not extend completely aci-oss the user so as to block the user attempting to rise from, or sit down into, the seat.

When the user is seated in the seat, or when the seat is tised by a user that does not require handle 40. handle 40 is preferably moved to its storage position so that the user is not impeded while sitting in, oi- rising from, the seat. As such, in the storage position, the liandle preferably does not extend across in front of the seat, and in the preferred embodiment. in the storage position, the llandle is positioned essentially cqual to, or outside of, the second end of support arnl 32, as shown in Tigure 5B.
Also, in the

-9-storage position, the device is not obtrusive while the seat user is seated since the handle is not located directly in front of the user..
Also, it is to be noted that in the embodiment shown in Figure 1, sleeve 30 might also be moved to the other end of base 16, and the sleeve attachnlent can be reversecl so that sleeve 30 points in the opposite direction. As a result, device 10 is preferably reversible, in that it can be positioned on either side of the chair.

When device 10 is not required, support ai-m 32 (witb handle 40) can be removed from sleeve 30. Sleeve 30 can tlien be optionally folded flat to the base, and lockin~
devices 18 i-eleased. The entire device 10 can then be easily moved or stored, for exainple, tulder the seat, where it is ready for later use.
Thus, it is apparent that there has been provided, in accordance with the present invention, a device to aid persons rising from, or sitting down into, a seated position which fully satisfies the goals, objects, and advantages set forth hereinbefore. Therefore, having described specific embodinlents of the present invention, it will be tuiderstood that altei-natives, modifications and variations thei-eof may be suggested to those sl:illed in the art, and that it is intended that the present specification embrace all such alternatives, niodifications and variations as fall within the scope of the appended clainis.

Additionally, for clarity and Lulless othei-wise stated, the word *'cornprise"
and variations of the word suc11 as "colnpi-ising" and "conlprises'", when used in the desci-iption and claims of the present specification, is not intended to exclude other additives, components, integers or steps.
Moreover, the words "sLibstantially" or "essentially", when tised with an adjective or adverb is intended to enhance the scope of tbe particular characteristic;
e.g., substantially planar is intended to mean planar, nearly planar and/or exhibiting characteristics associated wit11 a planar eleulent.
Also, while this discussion has addi-essed pi-ior art known to the inventor, it is not an admission that all ai-t discussed is citable against the pi-esent application.
