Abstract
A prop body (10) has, in addition to its telescopically adjustable outer section (11) and inner section (12), a screw (13) threadedly engaged in the distal end of the inner section (12). Sole plates (23, 24) are connected to the ends of the body (10), one sole plate (23) being connected rotatably to the outer telescopic section (11), the other sole plate (24) being non-rotatably connected to the screw (13). With the screw (13) held against rotation of its sole plate (24), the telescopic sections (11, 12) can be rotated in one direction or the other for screw-threaded extension or retraction of the prop body (10). Either or each sole plate (23, 24) may be connected to the prop body (10) by a universal joint (25, 31) so the prop can be used as a compression or tension member between surfaces to one or both of which it is oblique.
Description
_TτIT-τL-E: ADJUSTABLEBRACEORPROP
BACKGROUND OF THE INVENTION
(1) Field of the Invention
This invention relates to an improved adjustable brace or prop.
(2) Description of the Prior Art
Adjustable braces or props are well known and widely used in the building industry, such a device having an adjustably extensible body of two main parts telescopically interfitted, each having an apertured sole plate fixed to its outer end. The inner body part may be releasably locked in any of a number of adjusted positions by a retaining pin passed through longitudinal slots in the outer body part and round holes in the inner part and bearing against a nut engaged on a threaded portion of the outer body part, fine adjustment to the length of the device being obtained by rotation of the nut by means of an appropriate tool.
These articles, although very extensively used, have certain disadvantages. They can be used for angle bracing only with difficulty, this involving the install¬ ation of wedging blocks or the like, and their adjustment is rather laborious and time consuming.
The present invention has been devised with the general object of providing a brace, prop or strut of the general type set out which is far more versatile in its applications than those previously used, and which can be very quickly and easily adjusted for effective length. Other objects achievable in preferred embodiments of the invention are to provide such a device which can be used in tension as well as in compression, and which is simple and economical to manufacture, though particul¬ arly sturdy and durable in use.
BRIEF DESCRIPTION OF THE INVENTION With the foregoing and other objects in view,
the invention resides broadly in a prop of the type having a telescopically extensible or retractable body with sole plates at its extremities wherein the body includes a first end section, a second end section, an intermediate section telescopically engaged with the first end section and screw-threadably engaged with the second end section, means for releasably locking the intermediate section in selected slidably adjusted positions relative to the first end section, means for restraining the intermediate section against rotation relative to the first end section, means for connecting the distal end of the first end section rotatably to a first sole plate and means for connecting the distal end of the second end section non—rotatably to a second sole plate.
The first end section may be of square cross- section in which intermediate section, also of square cross-section, is slidably but non-rotatably engaged, a retaining pin through the sleeve and selected holes through the intermediate section releasably holding the two parts in desired telescopic adjustment; or the two parts may be of round section, the retaining pin then serving also to restrain one part against rotation relative to the other. A universal joint may be provided to connect the first end piece rotatably to the first sole plate, and a similar joint may be used for the non- rotatable connection of the second end piece to the second sole plate. After the prop has been brought to approximately required length by telescopic adjustment of the first end section and the intermediate section, final screw-threaded adjustment may be quickly obtained by rotation of the first end section by means of a handle, the second end section being restrained from rotation by its connection to the second sole plate. BRIEF DESCRIPTION OF THE DRAWINGS
In order that the invention may be readily understood and carried into practical effect, reference is now made to the accompanying drawings, wherein:- FIG. 1 is a perspective view of a prop according to the invention applied as an oblique stay or brace,
FIG. 2 is a sectional detail drawing showing parts of the prop,
FIG. 3 is a side elevation of a prop according to a modification of the invention, and
FIG. 4 is a side elevation of a further modified form of the invention.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring initially to FIGS. 1, 2 and 3 of the drawings, the telescopically adjustably body 10 of the prop includes a first end section or sleeve 11, an intermediate section 12 and a second end section or screw 13.
The sleeve 12 is a square-section metal tube with a capping plate 14 welded on its upper end.
The intermediate section 12 is a square-section metal tube slidably engaged in the sleeve 11 and having a sturdy cylindrical nut 15 welded to its lower or extended end. At its upper or enclosed end the inter- mediate section 12 has a limit piece 16 fixed on one of its faces and, when the intermediate section is fully extended, the limit piece is brought onto a stop piece 17 welded across the bottom of the corresponding face of the sleeve 11 and extending inwards for a short distance. Thus the intermediate section is prevented from being withdrawn from the sleeve.
The intermediate section 12 of the body is releasably retained in desired telescopically adjusted position relative to the sleeve 11 by means of a retaining pin 18, on a keeper chain 19, passed through
OMPI
._. _
a hole in one side of the sleeve 11, through any selected one of a series of pairs of opposed holes 20 in the intermediate section 12, and threadedly engaged in an axially bored and tapped boss 21 on the sleeve 11.
The second end section or screw 13 of the body 10 is engaged in the nut 15 of the intermediate section 12. By means of a handle 22 on the sleeve 11, this sleeve and the intermediate section 12 engaged in it may be quickly and easily rotated so that, if the screw 13 is restrained against rotation, the effective length of the body 10 will be increased, when the sleeve is rotated in one direction, and decreased with rotation in the opposite direction. A top sole plate 23 is connected to the upper end of the body 10, rotatably about the axis of the device, and a bottom sole plate 25 is connected non-rotat- ably to the lower end of the body.
In the embodiment shown in FIG. 1 the top sole plate 23 is connected to the top of the sleeve 11 of a universal joint indicated generally at 25, and consisting of a yoke 26 welded to the top sole plate 23, a further yoke 27 rotatable on a pivot 28 fixed to the capping plate 14 of the sleeve 11, and a connector piece 29 having its ends engaged on pivots 30, at right angles to each other, between the arms of the two yokes 26 and 27.
The bottom sole plate 24 is connected non-rotat- ably to the bottom of the screw 13 by a similar universal joint 31, consisting of yokes 32 and 33 welded respect¬ ively to the bottom sole plate 24 and the screw 12, and a connector piece 34 with its ends engaged on pivots 35 between the arms of the two yokes and at right angles. The two sole plates 23 and 24 are apertured to accept bolts 36, or screws, nails or other fasteners, by
means of which the sole plates may be secured in place.
As shown in FIG. 1, this prop may be used as an oblique brace, the bottom sole plate 24 being bolted to a horizontal surface, the top sole plate 23 being bolted to a vertical wall after the sleeve 11 and the intermediate section 12 of the boss- 10 have been telescopically extended or retracted to an approp¬ riate length and locked by the retaining pin 18, final adjustment of the prop being obtained by using the handle 22 to rotate the sleeve 11 and the partly enclosed intermediate section 12 relative to the screw 13. Although this final adjustment will usually be such as to cause the application of compressive force by the prop, the device may serve equally well as a tension member if necessary or desirable.
The embodiment shown in FIG. 1 is of course usable also as a vertical prop if it is not required to resist tilting," and it may be used as a jack for raising or lowering a structure supported thereby.
In the modified form of the invention shown in FIG. 3, the universal joints are dispensed with, the bottom sole plate 24 being welded to the bottom of the screw 13, a yoke 37 rotatably mounted the top of the sleeve 11 as before described having its arms welded to the top sole plate 23. In this form of the invention both sole plates are preferably more or less square rather than rectangular as shown in the embodiment of FIG. 1. In the embodiment of the invention shown in
FIG. 4, the sleeve 11a and the inter mediate section 12a of the body 10a are both of round-section tube, the retaining pin 18a being relied on to prevent relative rotation of the slidably interfitted parts as well as to hold these in telescopically adjusted relationship. The
P
form of the invention shown in FIG. 4, with the bottom sole plate 24a welded to the screws 13a and the top sole plate 23a connected rotatably to the top of the sleeve 12a by a universal joint 25a as before described, may be used to support an inclined structαr-e or formwork above a horizontal surface.
Any of the embodiments illustrated may also be used horizontally, for staying the sides of a trench, for example. Props according to the invention will be found to be very effective in achieving the objects for which they have been devised. It will, of course, be understood that the embodiments of the invention herein described and illustrated may be subject to many modific- ations of constructionaldetail and design, which will be readily apparent to persons skilled in the art, without departing from the scope and ambit of the invention hereinafter claimed.
