FR2747352A1 - Support cradle for gas bottles - Google Patents

Abstract

The support cradle has an articulated connection of the two cradle halves of tubular steel of 3/8 inch diameter welded to a steel plate (5). The gas bottle can be held by bungee cords passing through the hollow cradle tubes. The two half cradles can be folded together for compact transport. The folding can be allowed by hinges formed by pin and tube connections. The frames can have moulded rubber stops for the gas bottle. the half cradles can be held in a use position by a spring.

Description

DESCRIPTION
Db gas cylinder block cradle
This device is designed to immobilize domestic gas cylinders (13Kg butane / propane) during transport in a vehicle or for flat storage (FIG 1 to 8).

The extension of this invention (following Figures) will fulfill the same function for couples, or single bottles of larger dimensions (Ex: Model B20 or B50 oxy-acetylene of AIR LIIQUIDE) and will then be used rather for professionals (FIG 9 to 15).

Figure 1 is an isometric perspective (same unit on the 3 axes offset by 1200) representing the device (thick lines: 2) when in use, gas cylinder connected (thin lines: 1).

This connection is made using commercial tensioners
(ss), one of which can possibly be lodged in the throat
existing on this type of bottle.

The bottle then rests on the rubber pads of
cylindrical shape, split for placement, celled in
continued for their maintenance, and blocked in translation by a
welding point.

The device is also equipped with four tips in the
same material, or similar material fulfilling the same function
tion (anti-slip, anti-shock, anti-noise). These are em
force-cut or glued (FIG 2 on a 1/5 scale and its neck
partial eg).

The profile of the cradle alone (FIG 3), released from its bottle
shows the retaining spring in the tank position
stretched between the two joints (black parts).

The top view (FIGURE 4) shows the two half-cradles (4), linked together by a flat iron (5) folded at the ends, (stop function), with 4 small side plates, welded in the first fold and drilled for the passage of a split pin (6). (detail also in FIG 6)
The best solidity (longevity) / sale price ratio will certainly be obtained by using the commercial black steel heating tube f / 8 "(internal lkmm 17mm ext.) For the manufacture of the half-cradles. (Coating: epoxy resin paint).

As indicated on the front view (FId 5), the half-cradles are mainly made up of 4 pieces under s between 111: (autogenous welding, soldering, arc welding).

- 1 straight piece receiving the two end pieces
- 1 hot bent piece as a guide
and sheath to the tensioner
- 2 small straight pieces of binding
stiffness.

It remains to weld two small dishes and a small piece
angle iron transversely, at the base and in the middle of the
half-cradles, to make the joints (FIG 6/7/8).

SETTING UP LN PLACb OR REPLACING A TLNDbUR
- Cut the trade tensioner to the right of one of the two
metal hooks
- Introduce the cut end into one of the song entries
bent, push, bring it out to the other, slide
the hook in the same direction as at the origin (released before
washing of its rubber fall) over it.

- Tie the end (simple knot tightened with the vice, or bou
key crimped by a jumper) and push back the hook by
above.

Other materials (PVC, Polymers, Resin, Galvanized steel
Stainless steel, Brass, Aluminum) or other processes such as molding, gluing, machining, stamping or mechanical mounting are obviously possible for the manufacture of the 3 main elements (two 1/2 cradles + 1 connection), but a cost price study is necessary before a small series or industrialization.

- The pr.ototype exists and will simply be painted with a spray gun.

The partial section (full size) of Figure 6 shows the detail of the joint, with the 2 side pieces of flat iron and the end of angle iron (8) pierced (fi
spring fixing (7), length 250mm. 12mm) always
welded together and welded to the half-cradle.

The purpose of these joints is to be able to fold the 2
half cradles, to store the appliance flat with a
reduced dimensions (for example in the bottom of a trunk
private car where he can stay permanently).

as can be seen in the bottom view (FIG 7, the
spring is tight).

The tensioners then serve to keep the device folded,
the 4 hooks fixed on the large straight pieces of
half cradles (FIG b).

The perspective of FIG 9, gives the general conception
of the extension of the invention to twin-cylinder blocks
- the folding system is then produced using ar
ticulations of 4 pieces of tube (3/8 ") between the 2
half cradles (FIG 9/10/11/12).

- the locking in position of use is carried out with
of 2 sliding sleeves (FIG 13/14), thus forming
2 spacers.

FIG 10 gives the dimension of the two half-cradles for the B50 models of AIR LIQUIDE (10m3 ext. 229 / 242mu, height 1500 / 1650mm), a smaller model being necessary for the B20 models (4m3 d ext. 203mm, height 940 / 960mm).

We can also notice in FIG 10, the two superimposed tubes necessary for the passage of the two folds, one above the other.

As can be seen (FIG 11), the folded position is maintained by the free tensioners, as before.

The semi-folded position of FIG 12, gives the operation of the mechanism, the useful position of transport (sleeves blocked on the welding points 15 FIG 13) giving respective fixed axes X & 2 (FIG 9) of 1000 and 800mm for B50 and BSO models.

In FIG 13, scale 1/1, we can see the detail of the blocking using a sliding sleeve.

The articulations on the half-cradles and between the tubes are made by hinges in three parts welded alternately as shown in FIGS 14 & 15, and centered by a simple nail cut and hot-stamped at the other end.
