Abstract
ABSTRACT OF THE DISCLOSURE:
Adjustable shoring device for supporting a small vessel when erected on land. It is made up of four supporting members, two disposed on either side of the vessel, one at the stern and the other at the stem, in an inclined position relative to the vessel. The upper free ends of the supporting members abut against the hull of the vessel while their length and angle of inclination are adjustable to enable the abutment against the hull to be adapted to the size and shape of the vessel. The lower end of each supporting member is pivotally connected to one end of a connecting member that extends in either the trans-verse or lengthwise direction of the vessel, the other end of this connecting member being releasably clamped on and, upon release, being adjustable relative to an elongated base member secured below the keel of the vessel and extending in its lengthwise direction.

Description
~(~9~3()~
This invention relates generally to shoriny devices for small crafts ana, more particularly, to an adjustable shoring device for supporting small vessels when erec-ted on land.
In prior art, as disclosed in U.S.A. patent No.
3,204,910, there is described a shoring device which comprises supporting numbers disposed at either side of the vessel and provided at their upper free end with a supporting face for abutment against the hull of the vessel, the length and angle of inclination of said supporting members being adjustable to enable the abutment of the supporting face against the sides of the vessel to be adapted to the size and shape of -the hull.
A similar construction is also described in U.S.A.
patent No. 3,586,285 and in Swedish patent No. 379,977.
These known shoring devices, however, have several disadvantages. For one thing, they generally comprise a plurality of different components which are not adapted to be readily disassembled and, for another, they do not provide for adequate stability of the structure.
~` 20 Accordingly, it is a principal object of the invention to eliminate these disadvantages by providing a shoring device consisting of a relatively~small number o components of substantially similar construction which can readily be ~; assembled and disassembIed and which, in the disassembled condition, take up a minimum of space so as to facilitate transportation and storage.
; ~ Moreover~ it is a special advantage of this shoring :: :
device that, when in use, it ac-ts as a safety locking device for interlo~king the structure with the hull of the vessel, thereby eliminating any danger of acciden~al overturning of the vessel.
According to the invention, as herein claimed, the adjustable shoring device is characterized by the features that i ~""~
f~ ' f',~
~97300 the lower end of each supporting member is pivotally connected to one end of a connecting member extending in either the trans-verse or lengthwise direction of the vessel, the other end of said connecting member being releasably clamped on and, upon release, being adjustable relatively to an elongated base member secured below the keel of the vessel and extending in the lengthwise direction thereof.
In an embodiment of the invention, the elongated base member is adjustably clamped to a pair of blocks for supporting the keel of the vessel. The elongated base member will thus be firmly clamped to the blocks which, in turn, are secured by the weight of the vessel.
Both the elongated base member extending longitudinally of the hull and the connecting members interconnecting the base member with the supporting means are preferably tubular, and the connecting members which extend transversely of the hull releasably clamped to the base member between the keel supporting blocks, whereas the connecting members extending in the length-wise direction of the vessel are releasably clamped to the base member forwardly and rearwardly, respectively, of the keel supporting blocks.
For a fuller understanding of the invention, reference is had to the following description of preferred embodiments taken in connection with the accompanying drawings in which:
Fig. 1 is a schematic perspective view of a shoring device including four supporting members, as shown in detail in Fig. 4, Fig. 2 is a side elevation, Fig. 3 is a front elevation of the shoring device, Fig. 4 is a perspective view showing the details of a pair of supporting members and their adjustable connections with the elongated base member, ~1 - 2 -. ,,,~"~
~ ~09~3~
Fig. 5 is a perspective view showing a modified embodiment of one of the supporting members, and Figs. 5a and 5b show details.
Referring now to the drawings, there is shown in Fig. 4 one supporting member 20' for supporting the stem or stern of a vessel and another supporting member 19 for supporting one side of the vessel, which members 19, 20' will now be described.
Each of the supporting members 19, 20' comprises a substantially plane isosceles triangle structure having a pair of side legs 9, 9' interconnected by a cross bar 22, 22' and a tubular leg 12, 12' extending upwardly between the supporting legs 9, 9'. The lower end of the tubular leg 12, 12' is secured to the cross bar 22, 22', e.g. by welding, and a threaded bar 14, 14' carrying a supporting pad 16, 16' is adjustably disposed within the leg 12, 12'.
' The lower ends of the side legs 9, 9' are supported on the ground so that the angle of inclination of the structure 9, 12, 22 - 9', 12', 22' may be adjusted by tilting the structure around a horizontal axis at ground level. The bar 14, 14' being adjustable in the ,lengthwise direction of the tubular leg 12, 121, it wiLl be observed that both the length and the angle of inclination of the supporting member , are adjustable, so as to enable the supporting pad 16, 16' to be adapted to the size and shape of the hull ~, as shown more clearly in Figs. 2 and 3.
In each supporting member 19 and 20', the tubular leg , , 12, 12' is pivotally connected at 11, 11' to one end of a tubular connecting member 10, 10', the other end o~ which is pivotally connected with an adjustable clamp 13, 13"'on a horizontally extending tubular bar 8 and 8" , respectively.
One end of this connecting bar is pivotally connected at 21, 22' to the cross bar 22, 22' of the supporting member 19 or 20'.
73~)0 The other end of the bar 8" is pivotally connected to a cla}ap 13', which is releasably associated with a lengthwise extending base member 17. Similarly, the bar 8 pertaining to the side supporting member 19 is slideably and adjustably connected with the base member 17through a double clamp 6 and 7.
The base member 17 which is preferably a longitudinally extending steel tube is secured by means of pairs of adjustable clamps 4, 4' - 4" , 4"' to a pair of keel supporting blocks 1, 1'. Thus, when -the vessel is disposed on the blocks 1, 1', the base member 17 will be firmly secured relatively to the ground.
When the shoring device, the complete structure of which comprises a pair of stem and stern supports 20' and a pair of side supports 19, as shown schematically in Fig. 1, shall be adapted to the shape and size of a hull A, as shown in Figs. 2 and 3, the angle of inclination is adjusted by tilting each supporting member around a horizontal axis at ground level, as described, and the length of the supporting legs 12, 14 -12', 14' is ad~usted until the supporting pads 16, 16' abut the hull. After this adjustment, the clamping devices 13' and 6, 6' are firmly clamped to the base member 17, and the clamps 7, 7' are similarly clamped to the connecting members 8' 8', thereby securing the supporting members 19 and 20' to the base member 17.
In the embodiment shown in Fig. 6, the shape of the supporting member 30 i5 modified by providing a subs-tan-tially U-shaped structure including two tubular legs 32, 34 with adjustable extensions 36, 37 carrying the supporting pads and interconnected by subs-tantially V-shaped structures 35 and 35'.
In this embodiment, each of the tubular legs 32, 34 is pivotally connec-ted with one end of a connecting bar 38, 39, the other end of which is pivotally connected with horizontally extending connecting bars 82, 84 corresponding to the bar 8 of Fig. 4.

Otherwise, the shoring device of this embodiment is identical with the embodiment described with reference to Figs. 1, 2, 3 and 4.
