Abstract

<P> The invention relates to a device preventing these rods from falling when they are no longer held. It consists of a sliding sleeve (1) installed on the rod base (2) on which are fixed opposite 2 annex feet (3) connected by 2 rods (10) to an oscillating bracket (4), fixed behind the sleeve. A stop ring (7) adjusts the stroke, 2 other links (12) connect the adjoining feet (3) to the rod base (2) by means of a ring (11) flanged on the latter. When the sleeve (1) controlled by a handle (9) is raised, the auxiliary feet (3) rise from the height of the stroke, are aligned as close as possible to the foot of the rod (2). A lock (9) installed on the handle (5) makes it possible to maintain this position. When the sleeve (1) is lowered, the auxiliary feet (3) deploy, thus constituting with the cane foot (2), a substantially equilateral tripod, allowing the cane to remain upright. </P>

RETRACTABLE FALL PROTECTION DEVICE
ADAPTABLE ON ENGLISH RODS
The present invention relates to a device preventing the English rods, when they are no longer held manually, from falling, whatever the ground.

 Traditionally, apart from a specific cane called "tripate" (fixed), there are no canes that can stand alone without falling.

 The device according to the invention overcomes this drawback.

 It has in fact, according to a first characteristic, 2 annex feet fixed opposite by an articulation, on a sliding sleeve between a stop ring and the base of the cane butt. This sleeve is provided with a control handle.

 According to a second characteristic, 2 symmetrical links between them, connect the annex feet to an oscillating stirrup fixed on the sleeve. The position of the latter (low or high) allows the lateral separation or the closing of the annex feet.

According to a third characteristic, 2 other symmetrical links between them connect the annex feet to the foot of

cane, via a second ring clamped on it.

These rods allow the auxiliary feet to move backwards or to close in perfect synchronization with the lateral spacing rods, making it possible to form with the cane foot, when the sleeve is lowered, a tripod whose base forms a substantially equilateral triangle and when the sleeve is raised, a perfectly compact and compact assembly, formed by the alignment of the adjoining feet along the cane foot.

The race of the sleeve, adjustable by the stop ring, allows the auxiliary feet to go up by the same amount, which allows normal use of the rod without any discomfort.

 According to a fourth characteristic, a keying groove is made, preferably inside the sleeve and the so-called stop ring. A sufficiently long key integral with the latter is intended to allow the control handle, fixed on the sleeve, to remain in permanent alignment with the axis of the rod handle.

 According to a fifth characteristic, the control handle comprises at its end, a locking system making it possible to keep the adjoining feet closed, the unlocking being done by simple pressure of the finger, or by striking the cane foot with a short blow on the ground.

<Desc / Clms Page number 2>

 According to the particular embodiments: - The articulations of the auxiliary feet and the rear spacing rods can be produced using ball joints or any other system allowing rear and lateral movement.

 The other joints can be made using screws, rivets or clips, as well as for adjusting the height of the ancillary feet.

 - The attachment of the additional feet can be offset backwards on the sleeve in order to reduce the size when they are closed.

 - The sliding of the sleeve can be helped by a compression, traction or spacing spring.

- In order to limit the clearances and the bulk, the fixing of the rods on the annex legs can be carried out by including them in lights practiced in them.

 - The sleeve and the rings are preferably made of cast aluminum or machined from a tube with a minimum thickness of 7 mm. Other materials may be used, provided they have at least equal sliding and weight qualities.

- The control handle can be locked by pinching, by rocking around the cane handle, or by any other means allowing the assembly of the system as a kit, without ever modifying the original cane.

 The accompanying drawings illustrate the invention: Figures 1,1a, 2 and 2a show the device according to the invention.

Figure 3 shows the detail of the sleeve and the rings.

With reference to these drawings, the device comprises, according to FIG. 2a, a sleeve (1) sliding on the upper part of the cane foot (2). On this sleeve are fixed: 2 feet

Figure img00020001

annexes (3), 1 oscillating bracket (4) and according to Figure 2, a control handle.

 According to Figure 3 in the sleeve (1) has been dug a keyway (6) as well as in a ring (7) (called stop).

In this groove has been inserted a key (8) made integral with the ring (7), in order to always guide the sleeve (1) in the axis.

 According to Figure 2, the control handle (5) has at its end a locking system (9) by pinching (in the chosen option).

<Desc / Clms Page number 3>

 According to Figure 2a, on the oscillating stirrup (4) are fixed 2 rods (10) (called lateral spacing), connected to the auxiliary feet (3).

On a second ring (11) are fixed 2 other rods (12) (called rear spacers), also connected to the adjoining feet (3).

The latter are adjustable in height by sliding the tubes (13).

 According to Figures 1 and 1a, the control handle (5) determines the position of the sleeve (1). Raised, the adjoining feet are raised and aligned along the cane foot. This can then be used normally.

 According to Figures 2 and 2a, the control handle (5) is lowered, the auxiliary feet (3) are deployed, the rod then stands alone.

Claims (6)

1) Retractable anti-fall device, adaptable to English rods, characterized in that it comprises a sliding sleeve (1) a control handle (5) with locking (9), a so-called stop ring (7), 2 symmetrical links between them, called lateral spacing links (10), of a second ring (11) on which are articulated 2 other symmetrical links between them, called rear spacing links (12).
 2) Device according to claim 1 characterized in that it comprises 2 annex feet (3) fixed opposite by an articulation on the sliding sleeve (1), itself controlled by a handle (5), rising or lowering according to use.
 3) Device according to claims 1 and 2 characterized in that the 2 links (called lateral spacing) (10) connect the auxiliary feet (3) to an oscillating stirrup (4) fixed behind the sleeve (1), the position of the latter (low or high) allowing the lateral spacing or the closing of the annex feet (3).
 4) Device according to claims 1 and 3 characterized in that the other two links (12) connect the adjoining feet (3) to the rod base (2) via a second ring (11), clamped on this latest. They allow the spacing of the annex feet (3) rearward or to close in perfect synchronization with the so-called lateral spacing rods (10) allowing, depending on the high or low position of the sleeve (1), the formation with the cane leg (2) of a tripod, the base of which forms a substantially equilateral triangle or of a perfectly compact assembly and of minimum bulk formed by the alignment of the ancillary feet (3) along the cane leg ( 2).
 5) Device according to claims 1 and 2 characterized in that a keyway (6) is preferably made inside the sleeve (1) and the so-called stop ring (7). The purpose of a sufficiently long key (8) integral with the latter is to allow the control handle (5) to remain permanently in the axis of the rod handle.
 6) Device according to claims 1 and 5, the control handle (5) comprises at its end, a locking (9), by pinching (in the chosen option), allowing to keep closed the attached feet (3). Unlocking is done at the touch of a finger.
