At the top of the semi circular member 23 is a pivotally mounted latch 33 which has one end 33″ pivotally mounted to the top of the semi circular member 23.
Mounted to the top 32 of the base 21 of the storage device 20 is a V shaped plate 34 with a curved pointed member 35 fixed to the top 29, adjacent to V shaped plate 34 and spaced inside the V shaped plate.
The conventional telescoping sleeve apparatus 26 of a conventional panel lift device, which acts to lift the cradle 27 of the conventional panel lift device, has a V shaped column 26′ along the front side of the outermost sleeve 30 with two telescoping sleeves 30′ and 30″ mounted inside the outer sleeve 30 to telescope upward out of the sleeve 26′ to raise the cradle 27
When attaching the telescoping sleeve component 26 to the storage device 20, the telescoping sleeve is placed so the bottom 26″ of the V shaped column 26′ is received between the V shaped plate 34 and pointed member 35 of the base of the storage device, when mounting the bottom of the telescoping member 26 of a panel lift device to the storage device 20.
The top of the V shaped column 26′ of a panel lift device is thereafter engaged against the diverging flanges 36 and 36′ fixed to the top of the semi circular member 23 of the storage device 20, when mounting the top of the telescoping member 26 of the panel lift to the semi circular member at the top of the storage device 20.
The latch 33 is pivotally mounted to the top of the semi circular member of the storage device about pivot 65. The latch 33 has a downwardly pointed end member 33′ which is spring loaded downwardly by a spring 33′″ at the opposite end of the latch. The latch has a projection 64 at its opposite end with the spring 33′″ surrounding the projection and with the spring engaging the floor 64 to which the latch is pivotally mounted so that the spring urges the pointed end 33′ of the latch downward as shown in the drawing. The latch may be manually lifted counter clockwise upward about its pivot 65, as viewed from
The horizontal bar or horizontal post 37 is fixed to the upright post 22 of the storage device, intermediate the height of the post 22 of the storage device. The horizontal post 37 extends horizontally to each side of the post. On one side 37′ of the horizontal post are a pair of frusto conical channel plates 38 and 38′ each having downward and inward converging channel portions 39 and 39′ along their outer edges.
To attach the lateral brace members 28 and 28′ of the conventional panel lift device to the storage device 20, the brace members are attached and stored on the conical plates 38 and 38′ on the horizontal post 37 of the storage device. Each brace member 28 and 28′ has a frusto conical plate 58 and 59, which when the panel lift device is assembled fit into the frusto conical plates with channels 48 and 48′ of the cradle. The frusto conical plates 58 and 59 of the brace members are adapted to be slide downward into the channel portions 39 and 39′ of the channels 38 and 38′ pf the storage device to their positions, as shown in
The floor support tripod 25 of a conventional panel lift device has three arms outer 41, center 41′, and outer 41″ which are pivotally mounted to a center support 42. The center support has a v shaped flange 32 with a pointed flange 32′, which receives the bottom of the V shaped column 26′ of the telescoping sleeve when assembling the panel lift device.
Each arm of the floor support has a rotatable wheel 43′ mounted to their our ends. The three arms 41, 41′, and 41″ of the floor support are pivotally moved outward radially to 120 degree spacing between them when using the floor support to support telescoping sleeve with the cradle thereon and lateral support components of the panel lift device.
The V shaped flange 32 and point flange 32′ of the floor support is similar to the storage V shaped flange 34 and pointed member 35 on the base 21 of the storage device, and which also receives the bottom of the V shaped column 26′ of the telescoping sleeve in a similar manner when storing the telescoping sleeve 26.
The legs of the floor support 25 of the conventional panel lift are adapted to be attached to the other side 37″ of the horizontal post 37 of the storage device, opposite the mounting location of the with the other side 37′ of the post adapted to receive the lateral braces 28 and 28′ of the conventional panel lift device.
On the base 21 of the storage device is a V shaped cover 43, which is fixed to a horizontal bar 29 fixed at the front of the base 21 of the storage device. Beneath the cover 43 is an upright flange 44.
To attach the floor support 25 to the storage device for storage, the center support 32 of the floor support of the panel lift device is lowered and the end of the V shaped flange 32 is inserted beneath the V shaped cover and placed on the upright flange 44 in its position as generally shown in
The pivoting cover 45 on the horizontal post 27 will be pivoted outward about its horizontal axis 45′ relative to the post 37 to allow the legs of the floor support to be pivoted onward rearward toward and against the horizontal post 37 to a vertical position as shown in
Whereupon, the pivoting cover will be released and it is spring loaded to pivot counterclockwise laterally toward and against the brace 42 of the leg or arm 41 of the floor support to allow thea lateral front edge 45″ to engage around and in front against the front of the brace 42 of leg 41 as shown in
A projecting plate 45′″ is fixed to the bar or post 37 on the opposite side of brace 42 and projects forward to prevent any lateral movement of the brace 42 of the leg 41 laterally away from the cover toward the center post of the storage device. The pivoting plate 45, together with the projecting plate 45′″ act to lock the brace 42 of the leg 41 to the post 37. A second projecting plate 45″″ is fixed to the horizontal post 37 closer to the center post to prevent the leg 41″ of the floor support from moving toward the center post of the storage device.
An upper horizontal post 46 and lower horizontal post 47 are fixed to the main vertical post 31 of the storage device and extend horizontally outward. The posts 46 and 47 of the storage device are used to attach and support the main cradle 27 of a conventional panel lift device.
The main cradle 27 of a conventional panel lift device has a pair of tapered channel members 48 and 48′. Each channel member has confronting channels 49 and 49′ at the edges of a main plate portion 50 for receiving the frusto-conical shaped plates 58 and 59 of the lateral supports on a conventional panel lift device when operating and assembling the panel lift device.
When storing the cradle 27, the lower post 47 on the storage device has a slot 52 to receive the channel 48′ on the lower channel member of the cradle.
The upper post on the storage device has a lever 53 pivotally mounted to the upper post about axis 53′, and spring urged by spring 54 to pivot counterclockwise its hook end 53′″ pivoting rearward to engage about the edge of the main plate portion 50 of channel 48, when viewed from
When storing the cradle 27 on the storage device, the channel 49 of the channel 48′, at the lower end of the cradle, will first be fitted into the slot 52 on the lower post 47 of the storage device, and the upper end of the cradle will then be pivoted toward the upper end of the semi circular portion of the storage device until the upper channel 49′ of the upper channel member 48 rests against the slanted bottom of the upper post 46.
Whereupon, the lever 53 will be released and guided and urged by the spring 54 to pivotally move about the edge of the portion 50 of channel 48 to lock the upper end of the cradle 27 to the storage device as shown in
The pair of channel members 38 and 38′ of the storage device, which are fixed to the other side 60 of the horizontal post 37 and as indicated previously, act to receive the frusto conical plates 58 and 59 on the lateral supports 28 and 28′ of the panel lift device by sliding the plates down into the channel members as shown in
The lateral supports 28 and 28′ of a conventional panel lift device are customarily constructed with spring metal strips or straps 60 and 61, respectively. The straps each have their lower one ends 60′ and 61′, respectively, fixed to their respective lateral support and their other upper ends 60″ and 61″ preformed to spring out away to the left from their respective support to their position, as shown in
When the lateral supports are mounted to the channel members 38 and 38′ of the storage device, as shown in
The spring straps similarly serve, when the lateral supports are mounted to the channel members of the cradle of a conventional panel lift device, to lock the lateral supports to the cradle by their upper ends 60″ and 61 ″ of the straps engaging the lower edge 62 and 62′ of the channel members 48 and 48′ to prevent the straps 60 and 61 of the lateral braces 28 and 28′ from sliding out of the channel members 48 and 48′ of the cradle, thereby preventing the frusto conical plates 58 and 59 on the lateral supports 28 and 28′ from sliding out of the channel members 48 and 48′ of the panel lift device.
A pivotally mounted plate 63 is pivotally mounted to the channel members 38 and 38′ on the storage device to pivot about a horizontal axis 55 and has a handle 63″ to grasp to pivot the plate 63 upward relative to the channel members 38 and 38′ to cause the plate 63 at its forward edge 63″ to engage against the spring metal straps engage against back side of the of the upper portions 60″ and 61″ of spring metal straps 60 and 61 to urge them to the right when viewed from
The releasing of the handle 63′ will allow the spring straps to spring back to their normal position shown in
The storage device is constructed so that five components of the panel lift device, namely the telescoping sleeve mechanism 26, the leg support mechanism 40, the cradle 27, and the two lateral supports 28 and 28′ for the cradle may be removed or attached to the storage device in any desired order. The storage construction is such that none of the components interfere with one another so that none need to be attached or detached before the next component may be attached or detached. This enables easy removal or attachment of the components relative to the storage device.
Also, the storage device is provided with a positive locking mechanism for each of the components so that the components will remain locked to the storage device is a relatively fixed position so as not be become disengaged or loose on the storage device, when the storage device is upright or when it is tilted or placed horizontal with semi circular strap serving a rear leg support for the device to engage the ground with the two wheels serving as a front support for the device.
Thus it will be seen that a novel storage device has been provided for quickly and easily storing a conventional panel lift device thereon when not in use and which can be a conveniently wheeled to and from storage to a location for use and which provided a means for rapidly detaching and removing the components from the storage device when it is desired to assemble and use the panel lift device.
