DESCRIPCIONDESCRIPTION

Cierre de bisagra combinado, especialmente en envolturas protectoras o embalajesCombined hinge closure, especially in protective wraps or packaging

La invencion se refiere a un cierre de bisagra combinado en embalajes, envolturas protectoras o revestimientos de instrumented cientificos asf como medicinales, herramientas, en paquetes, etc... pero especialmente en envolturas protectoras para cargas propulsoras dispuestas en una barra de las aletas estabilizadoras de una granada de mortero.The invention relates to a combined hinge closure in packaging, protective wraps or coatings of scientific instrumented as well as medicinal, tools, in packages, etc ... but especially in protective wraps for propellant charges arranged in a bar of the stabilizing fins of a mortar grenade.

En las granadas de mortero las cargas propulsoras estan colocadas, por ejemplo, como anillos hendidos alrededor de la barra de las aletas estabilizadoras que se une en el lado de la parte trasera al cuerpo del proyectil. En el almacenamiento y el transporte de las granadas de mortero las cargas propulsoras sensibles a menudo a la mecanica y a la temperatura se protegen mediante una envoltura protectora adicional que encierra las cargas propulsoras (tambien dentro del embalaje de la municion).In mortar grenades, the propellant charges are placed, for example, as split rings around the bar of the stabilizing fins that are attached at the side of the rear to the body of the projectile. In the storage and transport of mortar grenades, propellant charges often sensitive to mechanics and temperature are protected by an additional protective envelope that encloses the propellant charges (also inside the ammunition packaging).

Las envolturas protectoras que se componen por ejemplo de plastico, la mayona de las veces de varias piezas se mantienen unidas mediante bisagras, grapas, pero tambien mediante cintas de velcro o cintas adhesivas que envuelven las envolturas protectoras.Protective wraps that are made up of plastic, for example, mayona of several pieces are held together by hinges, staples, but also by Velcro tapes or adhesive tapes that wrap the protective wraps.

Lo desventajoso en estas envolturas protectoras conocidas es, especialmente, que la retirada de las envolturas protectoras requiere relativamente mucho tiempo porque, o bien las cintas de velcro o cintas adhesivas deben desenrollarse, o deben separarse varias grapas, debiendo girarse la municion por lo general alrededor de su eje longitudinal, de manera que para la retirada de la envoltura protectora se necesiten varios segundos. Ademas, se necesita habitualmente mucho espacio libre para la retirada de los elementos de envoltura protectora.The disadvantage in these known protective wraps is, especially, that the removal of the protective wraps requires relatively much time because either the velcro tapes or adhesive tapes must be unwound, or several staples must be separated, the ammunition usually must be turned around of its longitudinal axis, so that several seconds are required for the removal of the protective wrap. In addition, a lot of free space is usually needed for the removal of the protective wrap elements.

En el documento DE 10 2007 050 981 B3 se describe un deposito protector para cargas propulsoras que sirve para la proteccion frente a danos e influencias ambientales de los cuerpos de cargas propulsoras configurados en forma de herradura, dispuestos sobre la barra de las aletas estabilizadoras de una granada de mortero, presentando los cuerpos de carga propulsora una abertura central en cada caso, asf como una hendidura radial que pasa a la abertura central para colocar deslizando los cuerpos de carga propulsora sobre la barra de la granada. El cierre del deposito protector presenta en este caso una primera pieza de cierre que posee una zona central que puentea las hendiduras radiales, que se extiende dentro de las hendiduras radiales en la direccion periferica, de manera que los cuerpos de carga propulsora presentan una posicion predefinida dentro del deposito protector de carga propulsora. Ademas, sobre la primera pieza de cierre esta sujeta al menos una pieza de agarre por medio de la cual puede tirarse de la primera pieza de cierre hacia afuera para abrir el deposito protector de carga propulsora y puede extraerse el deposito protector de carga propulsora. La union a separar de las dos piezas de cierre puede ser en este caso, por ejemplo, un cierre de velcro.In document DE 10 2007 050 981 B3 a protective tank for propellant charges is described that serves to protect against damage and environmental influences of the bodies of propulsive loads configured in the shape of a horseshoe, arranged on the bar of the stabilizing fins of a mortar grenade, the propellant loading bodies having a central opening in each case, as well as a radial slit that passes to the central opening to place the propelling loading bodies sliding on the grenade bar. In this case, the closure of the protective tank has a first closure piece that has a central area that bridges the radial grooves, which extends into the radial grooves in the peripheral direction, so that the propellant loading bodies have a predefined position inside the propellant charge protective tank. In addition, at least one gripping piece is attached to the first closure piece by means of which the first closure piece can be pulled out to open the propellant charge protective tank and the propellant charge protective tank can be removed. The joint to be separated from the two closure pieces can be in this case, for example, a velcro closure.

La invencion se basa en el objetivo de indicar una envoltura protectora para instrumentos de medicion o similares, para cargas propulsoras, especialmente para granadas de morteros u otros grupos constructivos a envolver o proteger que puede extraerse manualmente y en la mayor brevedad.The invention is based on the objective of indicating a protective envelope for measuring instruments or the like, for propellant charges, especially for mortar grenades or other constructive groups to be wrapped or protected which can be removed manually and as soon as possible.

Este objetivo se resuelve de acuerdo con la invencion mediante las caractensticas de la reivindicacion 1 o 5 respectivamente. Las reivindicaciones dependientes divulgan configuraciones adicionales, especialmente ventajosas de la invencion.This objective is solved according to the invention by the features of claim 1 or 5 respectively. The dependent claims disclose additional configurations, especially advantageous of the invention.

La invencion se basa fundamentalmente en la idea de realizar una bisagra como cierre de bisagra combinado empleado en la practica para unir al menos dos piezas.The invention is fundamentally based on the idea of making a hinge as a combined hinge closure used in practice to join at least two pieces.

Continuando con la idea, la envoltura protectora, embalaje, envoltorio etc... que se compone de al menos dos piezas en forma de cuenco y estan configuradas de tal manera, que en el caso del empleo conforme al uso previsto, encierran los grupos constructivos como instrumentos de medicion, cargas propulsoras, etc. en el lado exterior fundamentalmente en arrastre de forma, estan dotados de al menos un cierre de bisagra de este tipo. En este caso, cada una de las dos piezas en forma de cuenco esta unida fijamente con una cinta de tejido en el lado exterior en las zonas de extremo superiores e inferiores de su primer borde lateral con una cinta de tejido, de manera que entre las zonas de extremo superiores e inferiores se produce una zona de cinta de tejido en forma de bucle de buen agarre. Las dos piezas en forma de cuenco presentan en el lado exterior en las zonas de extremo superiores e inferiores de sus segundos bordes laterales una zona en cada caso, sobre la que esta fijado un primer elemento de cierre de una union en arrastre de forma como la de un cierre de velcro. Ademas, la cinta de tejido respectiva presenta, al menos en una zona que se une a su zona de sujecion, un segundo elemento de cierre de la union en arrastre de forma que con el primer elemento de cierre forma conjuntamente la union en arrastre de forma, de manera que la envoltura protectora puede fijarse en su posicion conforme al uso previsto.Continuing with the idea, the protective wrap, packaging, wrapping etc ... which consists of at least two bowl-shaped pieces and are configured in such a way that, in the case of use according to the intended use, enclose the construction groups as measuring instruments, propellant charges, etc. on the outer side, essentially in a trailed shape, they are provided with at least one hinge closure of this type. In this case, each of the two bowl-shaped pieces is fixedly connected with a fabric tape on the outer side in the upper and lower end areas of its first side edge with a fabric tape, so that between the Upper and lower end zones produce a loop-shaped area of good-grip loop tape. The two bowl-shaped pieces have on the outer side in the upper and lower end areas of their second lateral edges an area in each case, on which a first closure element of a drag joint is fixed in a manner such as the of a velcro closure. In addition, the respective fabric tape has, at least in an area that joins its fastening area, a second closure element of the drag joint so that with the first closure element jointly forms the drag joint , so that the protective wrap can be fixed in position according to the intended use.

Mediante el empleo de una envoltura protectora de este tipo con disposicion de cintas de tejidos de varias piezas con efecto de cierre de velcro se consigue que la cinta de tejido pueda asumir tanto la funcion de un cierre como tambien de una bisagra.By using a protective wrap of this type with disposition of multi-piece fabric tapes with velcro closure effect, it is achieved that the fabric tape can assume both the function of a closure as well as a hinge.

Para abrir la envoltura protectora solo se necesita agarrar y tirar con fuerza de una de las dos zonas de cinta de tejido en forma de bucle. Por ello se separan los elementos de cierre laterales asociados a esta cinta de tejido y la envoltura protectora se abre. La segunda cinta de tejido sirve entonces de bisagra, de manera que las dos piezas de envoltura no se caen y pueden ensamblarse de nuevo facilmente. En ejemplos realizacion practicos de la invencion, todo el proceso relacionado con la apertura y retirada de las envolturas protectoras duraba menos de 1 segundo.To open the protective wrap you only need to grip and pull hard on one of the two zones of loop-shaped fabric tape. Therefore, the side closure elements associated with this fabric tape are separated and the protective wrap is opened. The second fabric tape then serves as a hinge, so that the two wrapping pieces do not fall off and can be easily reassembled. In practical examples of the invention, the entire process related to the opening and removal of protective envelopes lasted less than 1 second.

Las piezas configuradas en forma de cuenco pueden componerse preferentemente de plastico, dado que las piezas de este tipo pueden fabricarse de manera asequible. Tambien son concebibles materiales alternativos como metal, aluminio o carton.The bowl-shaped pieces can preferably be made of plastic, since parts of this type can be manufactured affordably. Alternative materials such as metal, aluminum or cardboard are also conceivable.

En el caso de las dos cintas de tejido puede tratarse de cintas de frisa, cintas terciopelo (velour) o cintas de tipo seta de manera que las zonas de velcro separadas en las cintas de tejido pueden omitirse.In the case of the two fabric tapes, they can be fisa tapes, velvet (velor) tapes or mushroom tapes so that the velcro zones separated in the fabric tapes can be omitted.

En el caso del primer elemento de cierre puede tratarse por ejemplo de secciones de gancho o secciones de cinta de tipo seta. Se ha demostrado que se alcanza una resistencia mas elevada del cierre si se combinan entre sf frisa y una cabeza de seta.In the case of the first closure element, for example, it may be hook sections or sections of mushroom tape. It has been shown that a higher strength of the closure is achieved if they are combined between a quick and a mushroom head.

Alternativamente pueden emplearse tambien piezas en forma de cadena o de cinta, o bien de cuerda con uniones en arrastre de forma como cierre de bisagra combinado.Alternatively, pieces in the form of a chain or of a tape, or of a rope with trailing connections in the form of a combined hinge closure, can also be used.

En una forma de realizacion de la invencion esta previsto que las zonas en las que las cintas de tejido estan sujetas en las piezas en forma de cuenco y/o en las que estan dispuestos los dos elementos de cierre de los cierres de velcro esten configuradas en forma de solapa.In an embodiment of the invention it is provided that the areas in which the fabric tapes are held in the bowl-shaped pieces and / or in which the two closing elements of the velcro fasteners are arranged are configured in lapel shape.

Para que con una envoltura protectora cerrada las cintas de tejido se mantengan en una posicion de reposo definida, las piezas en forma de cuenco presentan en su lado exterior zonas de velcro adicionales que fijan las cintas de tejido dotadas con zonas de velcro correspondientes.So that with a closed protective wrapping, the fabric straps are kept in a defined resting position, the bowl-shaped pieces have additional velcro zones on their outer side that fix the fabric straps equipped with corresponding velcro zones.

Otros detalles y ventajas de la invencion resultan de los ejemplos de realizacion siguientes, explicados mediante figuras.Other details and advantages of the invention result from the following embodiments, explained by figures.

la figura 3 una variante adicional de la envoltura protectora en su posicion abierta.Figure 3 an additional variant of the protective wrap in its open position.

En la figura 1 la envoltura protectora, embalaje, etc... de acuerdo con la invencion esta senalado con 1. Se compone fundamentalmente de dos piezas 2, 3 (redondas o angulosas) en forma de cuenco preferentemente de plastico que pueden separarse una de otra completamente, que estan configuradas de tal manera que en su uso conforme al previsto en este ejemplo de realizacion encierran cargas propulsoras (no mostradas) de un mortero 100 de granada (figura 2) fundamentalmente en el lado exterior.In figure 1 the protective wrap, packaging, etc ... according to the invention is marked with 1. It is composed essentially of two pieces 2, 3 (round or angular) in the form of a bowl preferably of plastic that can be separated from one of another completely, which are configured in such a way that in their use in accordance with that envisaged in this example of embodiment they enclose propellant charges (not shown) of a mortar 100 of grenade (figure 2) mainly on the outer side.

Las dos piezas 2, 3 presentan en cada caso solapas 4-7 y 4'-7' laterales en las dos zonas de extremo superiores y en las dos inferiores de los bordes 8, 9 laterales y 8' y 9'. En este caso, a las solapas 4, 5 y 4', 5' laterales correspondientes del primer borde 8, 8' lateral respectivo de las dos piezas 2, 3 en forma de cuenco esta unido un extremo de una cinta 10, 11 de tejido configurada como cinta de frisa, de manera que entre las zonas de extremo superiores e inferiores se produce una zona 12, 13 de cinta de tejido en forma de bucle.The two pieces 2, 3 have in each case side flaps 4-7 and 4'-7 'in the two upper end zones and in the lower two of the side edges 8, 9 and 8' and 9 '. In this case, to the corresponding side flaps 4, 5 and 4 ', 5' of the first side edge 8, 8 'of the two bowl-shaped pieces 2, 3, one end of a fabric tape 10, 11 is attached configured as a frying tape, so that between the upper and lower end zones a zone 12, 13 of loop-shaped fabric tape is produced.

En las dos solapas 6, 7 y 6', 7' laterales de los segundos bordes 9, 9' laterales de las piezas 2, 3 en forma de cuenco estan sujetas en cada caso en el lado trasero secciones 14, 15 y 14', 15' de cinta de gancho que actuan conjuntamente con las cintas 10, 11 de frisa.In the two side flaps 6, 7 and 6 ', 7' side of the second side edges 9, 9 'of the bowl-shaped pieces 2, 3 are clamped in each case on the rear side sections 14, 15 and 14', 15 'of hook tape acting in conjunction with the 10, 11 frisa tapes.

Para ello la cinta 10, 11 de frisa respectiva se une en una zona que se conecta a su zona de sujecion (es decir, en la zona de las solapas 4, 5 y 4', 5') con las secciones 14', 15' y 14, 15 de cinta de gancho de la pieza 2, 3 en forma de cuenco adyacente en cada caso para formar un cierre de velcro, de manera que la dos piezas 2, 3 en forma de cuenco (y con ello tambien la envoltura protectora) se fijan en una posicion conforme al uso previsto.For this purpose, the respective belt 10, 11 is joined in an area that connects to its fastening zone (that is, in the area of the flaps 4, 5 and 4 ', 5') with the sections 14 ', 15 'and 14, 15 of hook tape of piece 2, 3 in the form of an adjacent bowl in each case to form a velcro closure, so that the two pieces 2, 3 in the form of a bowl (and thus also the wrap protective) are fixed in a position according to the intended use.

En la figura 1 la envoltura 1 protectora esta representada en su posicion abierta, de manera que solamente la cinta 11 de frisa que esta sujeta en las solapas 4', 5' laterales de la pieza 3 en forma de cuenco forma con las secciones 14, 15 de cinta de gancho de la pieza 2 en forma de cuenco union de cierre de velcro. Por ello para las dos piezas 2, 3 en forma de cuenco se produce una union de bisagra provocada por la cinta 11 de frisa.In figure 1 the protective wrap 1 is shown in its open position, so that only the frying tape 11 which is held in the side flaps 4 ', 5' of the bowl-shaped piece 3 forms with the sections 14, 15 of hook tape of piece 2 in the form of a velcro closure union bowl. Therefore, for the two bowl-shaped pieces 2, 3, a hinge joint is produced caused by the fisa tape 11.

Si deben protegerse cargas propulsoras correspondientes de los morteros 100 de granada entonces las dos piezas 2, 3 en forma de cuenco se pliegan alrededor de las cargas propulsoras y tambien la cinta 10 de frisa se une con las secciones 14', 15' de cinta de ancho para formar un cierre de velcro (figura 2).If corresponding propellant charges of the pomegranate mortars 100 must be protected then the two bowl-shaped pieces 2, 3 fold around the propellant charges and also the frying tape 10 joins the sections 14 ', 15' of tape width to form a velcro closure (figure 2).

Para finalizar las cintas 10, 11 de frisa se unen con zonas 16, 16' de velcro adicionales dispuestas en el lado exterior de las piezas en forma de cuenco y por tanto se mantienen en una posicion definida.Finally, the frying straps 10, 11 are joined with additional 16, 16 'velcro zones arranged on the outer side of the bowl-shaped pieces and therefore kept in a defined position.

Para abrir la envoltura 1 protectora, la cinta 10, 11 de frisa colocada de manera mas favorable en cada caso se agarra y se tira de ella con fuerza. Con ello se separa la cinta 10, 11 de frisa de las secciones 14', 15' o 14, 15 de cinta de gancho laterales asociadas a ella, y la envoltura 1 protectora se abre de nuevo. La otra cinta de tejido respectiva sirve entonces de bisagra (figura 1) de manera que las dos piezas 2, 3 en forma de cuenco no se caen y tambien pueden ensamblarse de nuevo facilmente.To open the protective wrap 1, the fisa tape 10, 11 placed more favorably in each case is grasped and pulled tightly. This separates the frying tape 10, 11 from the sections 14 ', 15' or 14, 15 of side hook tape associated therewith, and the protective wrap 1 opens again. The other respective fabric tape then acts as a hinge (Figure 1) so that the two bowl-shaped pieces 2, 3 do not fall off and can also be easily assembled again.

La figura 3 muestra una realizacion adicional de la envoltura 1 protectora. Esta se diferencia frente a la de la figura 1 especialmente en que esta prevista una sujecion 17 por ejemplo grapada o cosida en la seccion 14' o 15' de cinta de gancho mediante las que estan unidas las cintas 10, 11 de frisa con las piezas 2, 3 en forma de cuenco.Figure 3 shows a further embodiment of the protective wrap 1. This differs from that of Figure 1 especially in that a fastener 17 for example stapled or sewn in the section 14 'or 15' of hook tape is provided by means of which the tapes 10, 11 are joined together with the pieces 2, 3 bowl-shaped.

La invencion naturalmente no esta limitada al ejemplo de realizacion mostrado. Asf, en lugar de cintas de velcro tambien pueden emplearse de la misma manera cintas adhesivas autoadhesivas, piezas en forma de cadena, en forma de cinta o en forma de cuerda con uniones en arrastre de forma. La envoltura protectora puede componerse, en lugar de dos cuencos, de mas de dos segmentos en forma de cuenco de manera que es necesario un numero correspondiente de cierres de bisagra. Ademas, tal como ya se ha expuesto, la envoltura protectora puede estar prevista en otros usos, como por ejemplo como envoltura protectora para instrumentos de medicion (cientfficos, medicinales, minena, etc.). La envoltura protectora puede hacer las veces en estos casos de embalaje. Si se trata de grupos constructivos (100) poligonales el contorno interior de la envoltura protectora debe seleccionarse de manera correspondiente. El cierre de bisagra combinado puede emplearse naturalmente tambien en paquetes, formandose la envoltura protectora en este caso mediante las piezas de paquete.The invention is naturally not limited to the exemplary embodiment shown. Thus, instead of Velcro tapes, self-adhesive adhesive tapes, pieces in the form of a chain, in the form of a tape or in the form of a rope with trailing joints can also be used in the same way. The protective wrap may be composed, instead of two bowls, of more than two bowl-shaped segments so that a corresponding number of hinge closures is necessary. In addition, as already stated, the protective wrap may be provided in other uses, such as as a protective wrap for measuring instruments (scientific, medicinal, minena, etc.). The protective wrap can do the times in these cases of packaging. In the case of polygonal construction groups (100), the inner contour of the protective envelope must be selected accordingly. The combined hinge closure can of course also be used in packages, the protective envelope being formed in this case by means of the package pieces.
