The present technology relates to brackets for supporting portable equipment, and more specifically although not exclusively to brackets for supporting portable medical equipment.
Support for portable equipment, such as medical equipment, can be provided using brackets. Such brackets may be configured to be attachable to the portable equipment, and may include a handle for ease of carrying the portable equipment. In some cases, an attachment system may be provided for attaching the portable equipment and the bracket to a transportation system such as a stretcher, a wheelchair or a portable bed.
These types of brackets tend to have a plate-like structure and are made of metal in order to provide enough strength and rigidity to support heavy portable equipment. The portable nature of the equipment also requires that the bracket weight is kept to a minimum without compromising the strength of the bracket. However, material failure of these brackets is not uncommon, especially following impact to the bracket such as when dropped and other high load impact occasions.
Therefore, there is a need for brackets suitable for supporting portable equipment such as portable medical equipment and which overcome or reduce at least some of the above-described problems.
Embodiments of the present technology have been developed based on inventors' appreciation of at least one shortcoming associated with the prior art approaches to brackets for supporting portable equipment. Fractures and deformations of the brackets have been observed, especially after being dropped.

Referring initially to
The bracket 10 comprises a body 14 which is plate-like. The body 14 has an upper surface 16 and a lower surface 18. A portion of the upper surface 16 is arranged to contact the portable equipment 12 for supporting the portable equipment.
For ease of description, although the body 14 has a one-piece construction, it can be described as comprising three portions: a central portion 20, a first wing portion 22 extending from one side of the central portion 20, and a second wing portion 24 extending from another side of the central portion 20. The sides from which the first wing portion 22 and the second portion 24 extend are oppositely facing. The body 14 is symmetrical in that the first wing portion 22 is a mirror image of the second wing portion 24. However, in certain embodiments, the body 14 may be asymmetric (not shown).
Legs 26 extend from the lower surface 18 of the body 14. In the illustrated embodiment, four legs 26a, 26b, 26c, 26d are provided: a first leg 26a and a second leg 26b extending downwardly from the first wing portion 22, and a second leg 26c and a third leg 26d extending downwardly from the second wing portion 24. The legs are integrally formed with the body 14. In other words, the legs 26a, 26b, 26c, 26d and the body are a single piece. In other embodiments, the legs 26a, 26b, 26c, 26d may be separate and attached thereto. In yet other embodiments, there may be provided more or less than the four legs 26 illustrated herein. In use and in a resting position, when the legs 26 of the bracket 10 rest on a surface, the bracket can space the portable equipment from the surface.
The bracket 10 further comprises a handle 27 integral with the body. In other words, the body 14 and the handle 27 are a single piece. The handle 27 is formed in the central portion 20 of the body 14. In other embodiments, the handle 27 may be separate and attached thereto. In yet other embodiments, the handle 27 may be omitted.
Each of the first wing portion 22, the second wing portion 24, and the central portion 20 has a planar surface 28, 30, 32 which together define the upper surface 16 of the bracket 10. The planar surface 28 of the first wing portion 22 and the planar surface 32 of the central portion 20 is off-set by a first angle 34. The planar surface 30 of the second wing portion 24 and the planar surface 32 of the central portion 20 is off-set by a second angle 36. As best seen in
In alternative embodiments (not shown), the first angle 34 and the second angle 36 may be different to one another. In further alternative embodiments (not shown), the first angle 34 and the second angle 36 may be the same or different to one another and may range from about 2° to about 15°, or from about 3° to about 10° degrees, or from about 3° to about 7°.
Each of the first wing portion 22 and the second wing portion 24 are substantially trapezoidal in shape. A width 56 of the central portion 20 is more than a width 58 of each of the first wing portion 22 and the second wing portion 24. In the embodiment that is illustrated in
The central portion 20, at the upper surface 16 of the body 14, comprises a recessed portion 62 for receiving a plate 64 for connecting the portable equipment 12 to the bracket 10. The plate 64 is best seen in
Unlike the central portion 20, the first wing portion 22 and the second wing portion 24 are each a single piece with no openings. In other words, the planar surface 28 of the first wing portion 22 is uninterrupted, and the planar surface 30 of the second wing portion 24 is uninterrupted.
A total surface area of the upper surface 16 of the body 14, comprising a sum of the planar surface 28 of the first wing portion 22, the planar surface 30 of the second wing portion 24 and the planar surface 32 of the central portion 20, is more than about 35 in2 and less than about 100 in2, and in certain embodiments about 40-80 in2, about 50-80 in2, or about 70 in2.
The bracket 10 including the body 14 (first wing portion 22, second wing portion 24, and central portion 20), the legs 26 and the handle 27 are a single piece. The bracket 10 is made of a material having a higher impact toughness than aluminium or an aluminium alloy. The bracket 10 is made of a material which can withstand a static load of 200 lb or more. In certain embodiments, the bracket is made of acrylonitrile butadiene styrene (ABS). In other embodiments, the bracket 10 can be made of any other polymer such as a thermoplastic, an elastomer, or a thermoset polymer.
The bracket 10 can be made by any suitable method, such as injection moulding, casting, additive manufacturing, or the like.

A shoulder 158 extends around a portion of a periphery 160 of the planar contact portion 156 to define a pocket 162 for receiving at least a portion of the release member 136. The shoulder 158 is engageable with a portion of the flange 150 of the release member 36 when the release member 136 is positioned on the base member 134.
The base member front side 152 has an open access end 164 through which the release member 136 can be slidingly inserted and removed from the pocket 162. As can be seen, the base member 134 is four-sided, with the shoulder 158 extending around three of the four sides and the fourth side being the open access end 164. In other embodiments, the base member 134 may have different numbers of sides.
A stop member 166 is positioned in a recess 168 within the planar contact portion 156 of the base member 134 and is moveable relative to the planar contact portion 156. The stop member 166 is moveable to extend out of the recess 168 and to be housed fully in the recess 168 by a coupling lock mechanism 170 and an actuator 172. The stop member 166 is actuatable between a lock position in which at least a portion of the stop member 166 extends from the recess 168 and a release position in which the stop member 166 is retracted into the recess 168 and does not extend from the recess 168. In the lock position, when the base member 134 and the release member 136 are coupled together, the stop member 166 can abut an edge 174 of an opening 176 defined in the release member contact face 144 to delimit movement of the release member 36 towards the open access end 64 (
The actuator 172 is positioned at the open access end 164. The actuator 172 is a push button 178 housed within a groove 180 formed at the open access end 164. The actuator 172 can be moved between a neutral position and a deployed position. When the actuator 172 is in the neutral position (
