Definitions

• This type of device is already known and generally used by alpinists when abseiling or by speleologists when descending into chasms.
• An already old device on the market is in the form of an eight consisting of two closed rings. This device presents a delicate phase during its use. Indeed, during its installation this device must be completely free, which means that any awkward gesture can result in the loss of the descender by fall. Unfortunately this situation often occurs in the mountains or in the caves due to the cold and humidity.
• the present invention aims to provide a descender which remedies the faults mentioned above, that is to say a descender which cannot be lost and which requires simple manipulations which can be done quickly. These goals are achieved with the descender according to the invention.
• the invention will be better understood on reading the
• Figure 1 is a sectional view of an embodiment of the descender.
• FIG 2 is the same view as Figure 1 in which there is shown the different positions of the spring locking means.
• Figure 3 is the same view as Figure 1 where the loop is shown at the time of the dropout.
• Figure 4 is a view showing the attachment of the descen ⁇ deur harness.
• Figure 5 is a plan and side view of the loop.
• Figure 6 is a plan view, in profile and in section.
• Figure 7 is a plan view of a variant of the ring.
• Figure 8 is a perspective view of the spring means.
• the protuberance 24 comprises at its lower end an opening 28 (fig. 6) allows the free end of the loop 4 to come castrated, so as to constitute a closed carabiner 25.
• the two lower ends of the opening 28 for ⁇ two nose 6 and the loop 4 has a recess 7 constituting a hook.
• the spring 5 comes to hang on the nose 6 and is supported at the bottom of the recess 7.
• the loop 4 appears as a loop of a known carabiner comprising at one of its ends a hole 20 in which the axis 8 will pass and at the other end a hooking nose comprising a terminal surface 18 and two surfaces 19.
• the loop has, in addition to a known carabiner loop, two holes 12 intended to receive the spring 5.
• FIG. 6 shows that the ring 2 includes an opening 21 intended to receive the end of the loop 4 com ⁇ carrying the bore 20.
• the ring 2 in section to see how the protrusions 3 are formed.
• the latter each comprise a rectilinear part 3 and at their ends a return 23 at ninety degrees so as to constitute hooks.
• FIG. 7 represents a variant of the ring 2, in which instead of being circular the ring has the shape substantially of a semicircle.
• the descender 1 is used in the following manner: first of all the user fixes it to his harness by pressing on the spring 5 and by moving aside the loop 2 of the ring 4 as shown in FIG. 4. This manipulation can be done far from the vacuum and allows to use both hands which makes it safer, even if the hands are a little numb.
• the protrusions 3 have been provided to allow the user to stop in his descent with both hands free. It suffices for this that during the descent it surrounds the two protrusions 3 with the end of the rope while describing eight in the same way that the ropes are secured on the boats.
