Abstract
Description
- This invention relates to ambulance cots and in particularly, to a multi-level roll-in ambulance cot having a kickstand.
- Ambulance cots typically comprise an essentially rectangular patient support frame with wheeled collapsible-leg assemblies enabling the stretcher to be stowed or loaded into the back of an ambulance. Examples of such prior art cots are disclosed in U.S. Pat. Nos. 4,097,941, 4,192,541, 4,767,148, 5,537,700, and 5,575,026. Although the prior art cots have been generally adequate for their intended purposes, they have not been satisfactory in all aspects.
- Patients transported on an ambulance cot often need to be weighed as part of a medical check upon admittance to a hospital or other health care facility. Due to the size of the wheelbase of a cot and the size of platform scales generally found in clinics, hospitals, nursing homes, or rehabilitation centers, patients typically must either stand on the platform scale or be placed in a wheelchair in order to be weighed. For many of these individuals, standing or being transferred from the ambulance cot to a wheelchair is difficult, or impossible, to accomplish. Consequently, forgoing the weighing of such patients has become commonplace, which can degrade the quality of medical care provided to them.
- It is against the above background that the present invention provides a kickstand to a cot construction. Cot constructions of the present invention include a cot frame supported by a stable wheeled undercarriage, which permits the cot frame to be raised and lowered to a plurality of positions of use. The kickstand is provided to the wheeled undercarriage, and may be situated in at least raised and lowered positions. The kickstand when placed in the lowered position lifts one of the two pairs of wheels provided to the wheeled undercarriage into the air. By lifting one of the two pairs of wheels, the kickstand reduces the footprint of the wheeled undercarriage upon a support surface such that a patient situated upon the cot may be conveniently weighed on a platform scale.
- In one embodiment of the present invention, an ambulance cot comprising a kickstand having a lowered position and a raised position is disclosed.
- In another embodiment of the present invention, an ambulance cot for transporting a patient is disclosed. The cot comprises a cot frame for support the patient thereon, a wheeled undercarriage supporting the cot frame, and a kickstand mounted to the undercarriage.
- In still another embodiment of the present invention, a method of weighing a patient on a platform scale is disclosed. The method comprises carrying the patient upon an ambulance cot having a kickstand and a pair of wheels, and supporting the ambulance cot on the platform scale with the pair of wheels and the kickstand.
- These and other features and advantages of the invention will be more fully understood from the following description of some embodiments of the invention taken together with the accompanying drawings. It is noted that the scope of the claims is defined by the recitations therein, and not by the specific discussion of features and advantages set forth in the present description.
- The present invention is illustrated by way of example and not limitation in the accompanying figures, in which like references indicate similar elements, and in which:
-
FIG. 1 is a side view of a cot structure embodiment of the invention having a kickstand situated in a raised position and also illustrating a conventional platform scale; -
FIG. 2 is a side view of a cot structure embodiment of the invention having a kickstand situated in a lowered position and also illustrating the cot situated upon the conventional platform scale ofFIG. 1 according to the present invention; and -
FIGS. 3 and 3 A are top sectioned view of a portion of the embodiment ofFIG. 1 taken along section line 3-3, and showing the kickstand in a raised position. - Skilled artisans appreciate that elements in the figures are illustrated for simplicity and clarity and have not necessarily been drawn to scale. For example, the dimensions of some of the elements in the figures may be exaggerated relative to other elements to help to improve understanding of embodiment(s) of the present invention.
- Referring to
FIGS. 1, 2 , 3, and 3A, illustrated is a cot structure embodiment, generally indicated bysymbol 10, having a kickstand, generally indicated bysymbol 12, according to the present invention. Thecot 10 has arectangular undercarriage 14 mounting pairs ofswivel caster wheels 16 at its opposite ends. Theundercarriage 14 includes opposingside frame members transverse frame members FIG. 3 . - Extending upwardly from the
undercarriage 14 are pairs of cross formingframe members undercarriage 14 with a cot frame, generally indicated bysymbol 30.Cot frame 30 includes opposing tubular side frame members 32 (same on side not shown) interconnected at the foot or trailing end by a transversetubular end member 34. At their leading or forward ends, theside frames 32 each terminate at a respective hinge pivot 36 (same on side not shown). Supported by the pair ofhinge pivots 36 is adrop frame 38 rotatably coupled thereto. - The
drop frame 38 is releasable engaged by the pair ofhinge pivots 36, which also limits the range of motion ofdrop frame 38. In particular, thedrop frame 38 is movable from the extended position, as seen inFIGS. 1 and 2 , to a collapsed position placing the drop frame below thecot frame 30. Thedrop frame 38 is provided with a pair ofloading wheels 40. - It will be understood that the
basic cot frame 30 may be provided with various adjustable features, such as folding side arms (not shown), a multiple-position backrest, indicated generally at 42, and an adjustable leg section for placing the patient in a shock position, indicated generally at 44, all of which are conventional features. Other conventional features also may be provided in other embodiments. - The
undercarriage 14 is configured to selectively secure thecot frame 30 in a number of elevational positions relative to theundercarriage 14. The lowermost ends of thecross-forming frame members transverse frame member cross-forming frame members cot frame 30, and thecross-forming frame members cot frame 30. Thecot frame 30 is height adjusted by releasing a locking bar (not shown) thereby permitting thecross-forming frame members slots 46. At the same time, extensible sections 48 (same on side not shown) telescope within the lowermost ends ofcross-forming members cot 10 is repositioned, the sets ofcross-forming frame members cot frame 30 relative to theundercarriage 14. - As mentioned above in the background section of the invention, patients transported on an ambulance cot often need to be weighed as part of a medical check upon admittance to a hospital or other help care facility. A
platform scale 100 generally found in clinics, hospitals, nursing homes, or rehabilitation centers, used to weigh patients either standing or situated in a wheelchair thereon is shown. - The
cot 10 at the undercarriage provides thekickstand 12 which may be moved between a raised position (FIG. 1 ) and a lowered position (FIG. 2 ). The kickstand 12 when placed in the lowered position lifts one of the two pairs ofwheels 16 provided to thewheeled undercarriage 14 into the air as illustrated byFIG. 2 . By lifting one of the two pairs ofwheels 16, thekickstand 12 reduces the footprint of thewheeled undercarriage 14 upon asurface 50. In this manner, by reducing the footprint of thewheeled undercarriage 14 by lowering thekickstand 12, a patient situated upon thecot 10 may be conveniently weighed on theplatform scale 100. It is to be appreciated that the distance between one of the pair ofwheels 16 and the kickstand 12 (i.e., the footprint) is such that the total weight of the cot and patient may be placed upon theplatform scale 100 for weighing, such as illustrated byFIG. 2 . Accordingly, the patient conveniently does not have to be removed from thecot 10 in order to be weighed. - As shown by
FIG. 3 , thekickstand 12 includes au-shaped support bar 52 that is rotatably mounted between theside frame members kickstand mounts 54. Eachkickstand mount 54 is removably secured to its respectiveside frame member support bar 52 is spring-biased, via at least onespring 56, to the dropped position. In this manner, the u-spacedsupport bar 52 is returned to the raised position from the lowered position against the force of the spring(s) 56. - In still another embodiment, the
kickstand 12 includes acatch 58 and arelease 60. Moving therelease 60 from a locked position (as illustrated) to a release position, which is indicated by moving therelease 60 in the direction ofarrow 62, clears thecatch 58 with an engagement with apin 64 on theu-shaped bar 52, thereby causing theu-shaped bar 52 under the force of one of thesprings 56 to lower to the surface supporting thecot 10. Thekickstand 12 is then fully deployed by continuing to rotate thecot 10 over theu-shaped support bar 52 until being stopped in the fully lowered positioned illustrated byFIG. 2 . In the lowered position, therelease 58 also will secured theu-shaped bar 52 from movement. In another embodiment illustrated byFIG. 3A , the catch and release may be an integral unit, such as a springbiased lever 66. In such an embodiment, when arelease portion 68 is pivoted downwards against spring bias from aspring 90, acatch portion 92 is released from its engagement withpin 64. As the movement and positioning of theu-shaped bar 52 is the same as described above in the previous embodiment no further discussion is provided. - Upon a desire to raise the
kickstand 12, such as after a patient has been weighed on theplatform scale 100, therelease 60 is again moved from the locked position to the release position, and thecot 10 is either raised or rotated over theu-shaped support bar 52. Once theu-shaped support bar 52 is clear of the surface supporting thecot 10, it will return to the raised position, which is illustrated byFIGS. 1 and 3 , under force of the at least one of thesprings 56. In other embodiments, theu-shaped support bar 52 is manually placed in either the raised or lowered position, or both. - Accordingly, it is to be appreciated that a method of weighing a patient on a platform scale with the present invention is also disclosed. The method comprises carrying the patient upon the
ambulance cot 10, and moving the cot into position upon theplatform scale 100. Once so positioned, thekickstand 12 is placed in the lowered position. In this manner, thecot 10 is supported upon theplatform scale 100 with one of the pairs of wheels and thekickstand 12, such as illustrated byFIG. 2 . After recording the combined weight of the cot and patient and the patient has been transferred to another support surface, such as an operating table, bed, wheelchair, etc., the cot without the patient is then weighed (if unknown) in the same fashion as before on the platform scale. Accordingly, subtracting the weight of the ambulance cot from the combined weight of the ambulance cot and patient provides the weight of the patient. - In compliance with the statute, the invention has been described in language more or less specific as to structural and methodical features. It is to be understood, however, that the invention is not limited to the specific features shown and described, since the means herein disclosed comprise preferred forms of putting the invention into effect. The invention is therefore, claimed in any of its forms or modifications within the proper scope of the appended claims appropriately interpreted in accordance with the doctrine of equivalents. Any modification of the present invention that comes within the spirit and scope of the following claims should be considered part of the present invention.
