Description

UMBRELLA OF PROTECTION OF PERSON NALITIES

The invention relates to the protection of personalities, and in particular the equipment intended for the protection of personalities likely to be attacked during official journeys or appearances in public.

VIP protection is a thorny issue for security services. Indeed, any movement of a personality in highly frequented public places presents risks. The personality can thus be the object of aggression or be taken in a crowd movement.

The protection of personalities can be achieved by means of a number of anti-projectile tools. Suitcases or anti-projectile vests may be used in particular. Such a bag comprises in particular several articulated panels, which can be deployed to form a protection plate.

A bulletproof vest can not be worn under any circumstance by personalities and provides relatively limited protection against projectile throws, jets of harmful products or crowd motions. Furthermore, an anti-projectile case proves to be relatively bulky for a reduced ease of deployment and an imitated protection surface. In addition, a suitcase balances them is easily identifiable by an aggressor.

US4860776 discloses a shield for the protection of persons, in the form of a deployable umbrella. The umbrella fabric is sized to withstand the impact of a dog or projectile. This umbrella is optimized, in particular an opening spring, to obtain a very fast opening speed.

Because of its optimization for quick opening, this umbrella has a lower resistance of its fabric and has easily flexible ribs, to withstand at least the opening force. The protection of people is thus limited, since projectiles easily induce the destruction of whales or their attachment to the flowing.

The invention aims to solve one or more of these disadvantages.

The invention thus relates to an umbrella for personal protection, comprising:

-Matt ;

a coulant slidably mounted on the mast;

-an anti-laceration canvas;

first whales supporting the anti-laceration fabric;

second whales integral with the flowing and the first whales, the second whales being configured to deploy or retract the canvas antilacérations during the sliding of the flowing on the mast;

the flowing comprising a monobloc support in which grooves are formed, these grooves housing one end of the second mounted whales pivoting through pins, said pin each extending perpendicular to the axis of a respective second whale.

According to one variant, said pin is a full metal pin.

According to another variant, the one-piece support is made of metal.

According to another variant, first ends of the second whales comprise endpieces provided with flat surfaces housed in said grooves with a smoothly sliding.

According to yet another variant, the umbrella comprises a nut attached to one end of the mast, the nut comprising a one-piece support in which grooves are formed, these grooves housing one end of the first whales pivotally mounted by means of pins, said pins each extending perpendicular to the axis of a respective first whale.

According to one variant, the mast is formed of a tube made of resin reinforced with carbon fibers.

According to another variant, the anti-laceration fabric comprises at least one impermeable outer layer superimposed on an anti-laceration layer.

According to one variant, the flange comprises a gripping handle having a gripping length greater than 60 mm.

According to another variant, the handle is not covered by the anti-laceration fabric when the umbrella is in the closed position.

According to yet another variant, the umbrella comprises another gripping handle sol idaire one end of the mast, the gripping handle of the flowing being disposed between the solitary gripping handle idaire mast and said goupil them.

Other characteristics and advantages of the invention will emerge clearly from the description which is given hereinafter, for information only and not at all imitative, with reference to the appended drawings, in which:

FIG 7 is a side view of a junction between two types of whales; FIG. 8 is a view from above of a component of a nut of the umbrella of FIG. 1; FIG 9 is a side view of the component of Figure 8;

FIG. 10 is a view from above of a stop of a nut of the umbrella of FIG. The invention provides an umbrella for protection of personalities having a mast, a runner mounted sliding on the mast and an anti-laceration cloth. The anti-laceration canvas is ideal soil of first whales. Second whales are integral with the flowing and the first whales to allow the deployment or retraction of the anti-laceration fabric during the pouring of the flowing.

The coulant comprises a monobloc support in which grooves are formed. A groove houses one end of a respective second whale. This second whale is pivotally mounted by means of a pin. This pin extends perpendicularly to the axis of this second whale.

Such an umbrella is particularly discreet, has a large area of protection and is usable with great maneuverability. The invention provides a fairly lightweight umbrella, optimizing its maneuverability. Furthermore, the securing of the second whales by such a pin system and the retention in the grooves ensures excellent mechanical strength at the junction between the second whales and the flowing, this junction being particularly stressed in case projectiles or thrust exerted on the anti-laceration cloth. Such an umbrella can thus be used as a shield to repel the crowd.

Figure 1 is a schematic sectional view of an embodiment of a protective umbrella 1 according to the invention. The umbrella 1 comprises in a manner known per se a mast 2, on which a handle 3 is fixed at its lower end. A coulant 4 is mounted coul issant on the outer surface of the mast 2. A nut 5 is fixed to the upper end of the mast 2.

An anti-laceration fabric 604 is secured to first whales 603. The anti-laceration fabric 604 is also attached to needles 650 placed at the free ends of the first whales 603. The attachment of the fabric 604 to the needles 650 may for example be made by means of a kevlar thread, guaranteeing a resistance of the link aiguillette / canvas to shocks. The umbrella 1 comprises in this case eight whales 603 distributed around the mast 2. The whales 603 comprise end pieces 640 through which these whales 603 are pivotally mounted on the nut 5. Each whale 603 is pivotally mounted relative to the nut 5 around a respective axis perpendicular to the axis of the mast 2 and to the axis of this whale 603.

Each whale 603 is coupled to a respective whale 602 of a group of second whales. Each second whale 602 has a tip 610 at a first end. Every 602 whale is mounted pivoting relative to the channel 4 via its tip 61 0. Each second whale 602 also has a tip 620 at a second end. The tip 620 is pivotally mounted on a stirrup 630. Each whale 602 is pivotally mounted relative to the channel 4 about a respective axis perpendicular to the axis of the mast 2 and to the axis of this whale 602. The stirrup 630 is attached to a respective whale 603, for example by clamping.

When the coulant 4 slides in the direction of the nut 5, the whale 603 is removed from the mast 2 by means of the whales 602, the whales 602 acting as biel lettes. This is the deployment of the umbrella 1.

The umbrella 1 further comprises bending springs 201 and 202 housed inside the mast 2. The bending springs 201 and 202 have a portion in line with the outside of the mast 2, respectively defining a deployment position and a retracting position for the flowing 4. The portions sail tied are pushed inside the mast 2 by the flowing 4 when the coulant 4 coulis isse on the mast 2.

Advantageously, the flange 4 comprises a gripping handle 43. The handle has a grip length greater than 60 mm, preferably greater than 80 mm. Such a handle 43 allows a user to deploy pl us easily and quickly the canvas 604 when opening the umbrella. This is particularly advantageous for such an umbrella, the deployment effort may be greater than on a commonly used umbrella and the speed of deployment of the fabric 604 proving crucial for such an umbrella of security. Advantageously, the handle 43 is not covered by the fabric 604 when the umbrella 1 is in the closed position. When the umbrella is in the open position, the handle 43 allows the user to apply greater effort with both hands. The gripping handle 43 is disposed between the gripping handle 3 and the pin 601 securing the ribs 602 to the flange 4.

The handle 43 of the illustrated example is aluminum and its outer surface is knurled to improve the grip of the hand of the user. The handle 43 comprises a median bore traversed by the mast 2. The handle 43 is attached to the flange 4 and fixed to the flange 4 by screwing with screws 44, for example 4 in number and angularly distributed. The umbrella 1 advantageously has a tape 302. The tape

302 ill ustré is nested at the end of the mast 2 and is fixed by col lage. The tape 302 is advantageously made of metal and has a conical end to use the umbrella 1 as a defense weapon. FIG. 2 is a top view of a set of components of the umbrella 1 at the level of the flange 4. The flange 4 comprises a slide 400 and a stop 450. Pins 601 are housed in a housing of the slide 400 and held by the stop 450. The isse 400 is made in one piece, the mechanical strength of the slide 400 is thus optimized. Advantageously, the 601 pins are solid pins to enhance their shear strength. The pin 601 can guide the tips 61 0 in rotation about their axes, and transmit forces between these tips 610 and the flowing 4.

FIGS. 3 and 4 are top and side views, respectively, of the isse 400. The isse 400 comprises a tubular wall 403 having an internal bore 420. The tubular wall 403 serves to guide the flow 4 by casting along the mast 2. The bore 420 is thus made with a smoothly sliding with the outer surface of the mast 2. Polytetrafluoroethylene rings 425 are advantageously fitted to both ends of the tubular wall 403. These rings 425 polytetrafluoroethylene allow to avoid scratching the mast 2 and promote easy sliding of the channel 4 on the mast 2. The tubular wall 403 has a groove 424 for receiving the projecting portion of the spring 201 or the spring 202, in order to immobilize the flowing deployment position or in retracted position.

A housing for the pins 601 is formed in the upper part of the slide 400. This housing is delimited by a peripheral wall 402, and by a bottom wall 401. The bottom wall 401 has a disk shape in the example. The bottom wall 401 has notches 422 for receiving the pins 601. Thus, in a cross section of the bottom wall 401 at the notches 422, the same plane passes through the pin 61, the side faces 41 1, 412. In this plane, the bottom wall 401 forms a junction of material continuous between two successive grooves 421. This junction of material is particularly resistant to stresses applied to the lateral faces 41 1 and 412. Thus, the strength of the connection between a tip 610 and the slide 400 is particularly strong, particularly with respect to a rotation about the axis of the whale attached to a tip 610 or vis-à-vis a rotation of the tip 610 about the axis of the mast 2. Grooves 421 are formed in the peripheral wall 402 and in the bottom wall 401. These grooves 421 are intended to receive end-pieces 610, as shown in FIG. 2. The grooves 421 are fitted in a smoothly sliding manner with the ends of the end-pieces 610. Thus, the end-pieces 610 can turn around the pins 601 but can not can not move transversely inside the grooves 421, since they are retained by the side faces 41 1 and 412 of the grooves 421. Each notch 422 extends on either side of a groove 421. Threaded bores 423 are formed in the bottom wall 401. The threaded bores 423 are intended for fixing the abutment 450 by screwing on the slide 400. Figure 5 is a top view of a stop 450 which is fixed on the slide 400 so as to maintain the pins 601 in the notches 422. The stop 450 has grooves 451 coming directly above the grooves 421. The stop 450 also comprises bores 453 coming directly above the bores 423 and intended to be traversed by screws. The stop 450 is in the form of a wall 452 having substantially the shape of a ring.

Although not il ustré, the coulant 4 may also comprise an additional abutment clamping the pivoting of the end pieces 610 in order to avoid a reversal of the fabric 604.

Figure 6 is a side view of a tip 61 0. The tip 610 has an inductive cyl portion 61 1 in which a bore 61 2 is provided. The bore 612 is for receiving a shaft of a whale 602. The tip 610 has a substantially flat end 614. This end 614 has a bore 613 to be traversed by a pin. The end pieces 620 and 640 may have a structure strictly identical to that of the endpiece 610.

Figure 7 is a top view of a junction component including a ferrule 620 and a stirrup 630. The ferrule 620 has a cylindrical portion 621 in which a bore 622 is provided. The bore 622 is intended to receive a rod of a whale 602. The tip 620 has a substantially flat end 624. This end 624 is disposed in a jaw 626 of a stirrup 630. The end piece 620 is pivotally mounted in the jaw 626 via a screw 625. The bottom of the jaw 626 has a bore 627 whose axis is perpendicular to the axis of the screw 625.

The bore 627 is intended to be traversed by the shaft of a whale 603. By tightening the screw 625, it is advantageous to tighten the bore 627 on the whale 603. Thus, it is possible to immobilize the stirrup 630 at a position 603. Such a configuration makes it possible to guarantee a high mechanical strength of the connection between a whale 602 and a whale 603.

Figures 8 and 9 are respectively top and side views of the nut 5 according to the embodiment of the invention. The nut 5 comprises a support 500 and a stop 550. Pins 601 are housed in a housing of the support 500 and held by the stop 550. The pin 601 can guide the end pieces 640 in rotation about their axes, and transmit efforts between these tips 640 and the nut 5.

The support 500 comprises a tubular wall 503 having an internal bore 520. The function of the tubular wall 503 is to position the nut 5 on the upper end of the mast 2.

A housing for the pins 601 is formed in the upper part of the support 500. This housing is delimited by a peripheral wall 502, and by a fund wall 501. The bottom wall has notches 522 for receiving the pins 601. Grooves 521 are formed in the peripheral wall 502 and in the bottom wall 501. These grooves 521 are intended to receive ferrules 640. The grooves 521 are fitted in a sliding fit with the ends of the ferrules 640. Thus, the ferrules 640 can rotate around the pins 601 but can not move transversely to the inside. grooves 521, since they are retained by the side faces 51 1 and 512 of the grooves 521. Thus, the tips 640 can rotate around the pins 601 but can not move transversely within the grooves 521. Each notch 522 extends on either side of a groove 521. Threaded bores 523 are provided in the bottom wall 501. The threaded bores 523 are intended for fastening the abutment 550 by screwing on the slide 500.

Figure 10 is a top view of a stop 550 attaching to the support 500 so as to maintain the pins 601 in the notches 522. The stop 550 has grooves 551 coming directly above the grooves 521. The stop 550 also comprises bores 553 coming directly above the bores 523 and intended to be traversed by screws. The abutment 550 is in the form of a wall 552 having substantially the shape of a ring. Since the abutment 550 closes the housing of the support 500 from above, a maintenance operation on the umbrella 1, for example to change a whale 603, is relatively easy.

The mast 2 typically has a hollow tubular shape. The mast 2 can be made of epoxy resin reinforced with carbon fiber. The tube forming the mast 2 can be generated from a filament winding of carbon fibers. The mast 2 may have an outer diameter of about 16 mm. The use of carbon fibers to reinforce the mast 2 makes it possible to give it an excellent slow compressive strength for a contained weight. Other fibers having a high resilience, such as fiberglass or aramid fiber, can also be added to the carbon fiber in the resin of the mast 2. The mast 2 having a high compressive strength it makes it easy for a bodyguard handling the umbrella 1 to use it as a stick to repel people by being able to exert significant outbreaks.

The handle 3 can be fixed on the mast 2 by any appropriate means. In order to have an optimal mechanical connection, the handle 3 can be fixed to the mast 2 by collar (for example by means of an epoxy adhesive) and mechanical pinch. A pin 301 thus extends through the handle 3 and the mast 2. The handle 3 may have a strap 7 allowing the user to easily keep a socket of umbrella 1 even in case of significant effort. The handle 3 further advantageously has a peripheral band 300 having a high coefficient of friction to mimic the risks of sliding the user 's hand on the handle 3.

The nut 5 is advantageously fixed to the mast 2 via a transverse pin 303 and a collar.

The flow 4, the nut 5, the end pieces 610, 620, 640, the needle 650 and the stirrup 630 are advantageously metal parts. The different metal parts may be made of titanium or Fortal, in order to have an excellent slow strength / weight ratio. Fortal thus has an excellent strength / weight ratio. Stainless steel may be used for the caliper 630. The caliper 630 may also be made of titanium.

The whales 602 and 603 can be made with an epoxy matrix reinforced with carbon fiber to ensure their mechanical strength and fiberglass to allow their flexion. The proportion of carbon fibers among the fibers may be between 10 and 50% by weight. The proportion of glass fibers among the fibers may be between 50 and 90%. The whales 602 and 603 may be made in the form of shafts or tubes having an outside diameter of 6 mm. The whales 602 and 603 may, for example, be made by pultrusion.

The bores of the end pieces 610, 620 and 640 are advantageously threaded, even if the whales inserted therein are limited. In fact, such threaded bores make it possible to include a large amount of glue and make it possible to ensure debulking when the respective whales are introduced into the interior.

604 anti-laceration fabric can withstand perforations or lacerations with knives. The anti-laceration fabric may for example comprise a fabric anti-laceration layer of a weight of approximately 500 gr / m ² containing a mixture of 70% polyethylene and 30% polyester. The anti-laceration layer extends substantially over the entire surface of the fabric 604. The anti-aging fabric 604 may also include an energy absorption layer, made for example with an aramid fabric extending substantially over the entire surface of the fabric. 604. Such a layer makes it possible to damp projectile shocks and to brake any balls. The laceration fabric 604 may also include a flame retardant layer or a chemical spray resistant layer.

When the umbrella 1 is deployed, the cloth 604 has a large projectile protection surface. Such a surface is also favorable for protection against harmful products or against flames. The fabric 604 may for example have a wingspan of between 100 and 160 cm, for example between 120 and 140 cm. Moreover, when the umbrella 1 is deployed, the fabric 604 provides a large surface to be able to repel several people as a shield.

The fabric 604 can be made with several layers of fabric superimposed. The fabric 604 may in particular comprise a waterproof outer fabric, one or more intermediate layers with anti-laceration and / or shock absorption properties, and a tight inner layer. To facilitate the manufacture of one or more intermediate layers while maintaining a very high resistance to impacts, the intermediate layers can be formed by the assembly by overlocking of several sectors, each sector extending between two successive whales. The outer fabric may be a polycotton, for example containing 35% cotton and 65% polyester.

The anti-laceration fabric 604 is advantageously opaque to hide the personality once the umbrella Ί is deployed. Such masking makes it possible to make the location of the personality more difficult, and thus to imitate the accuracy of different aggressions, by projectiles or firing. The antilacérations web 604 is advantageously secured to the whales 603 by means of seams made in its overjets.

The umbrella 1 may advantageously be provided with a belt for holding the fabric 604 in the retracted position. Such a belt has a first end attached to the fabric 604. The belt has a second end libre can be fixed on the first end to form a loop around the fabric 604. Advantageously, the first end of the belt is attached to the fabric 604 by means of a removable attachment, for example a velvet type fastening and hooks. Such removable attachment prevents a person in the crowd tears the umbrella 1 from the hands of his user is pulling on the belt. If a person tries to exert a significant traction on the belt, it then disengages from the umbrella 1.
