In particular, these improvements have enabled the load to be transported to be securely attached to a backpack frame, and the transport characteristics have also been such that the device can handle carriers, stretchers or baskets, and sleds as well. be.

[Means and actions for solving the problem]

According to the present invention, the above object is as follows: four longitudinal beams are arranged in one space so as to substantially correspond to the ridgeline of the square column, and a pair of longitudinal beams on the carrying part side and a pair on the loading part side The two loading section side longitudinal beams form a sliding surface, and both pairs of one loading section side longitudinal beam and one carrying section side longitudinal beam form a backpack carrier frame 2. A backpack frame comprising two narrow side parts, a plurality of horizontal beams connecting the vertical beams, and having a carrier belt shape, the backpack frame having two lower ends connectable by a coupling, and A knapsack frame which can thus form a platform for transporting or towing on the ground, comprising a sliding plate parallel to the sliding surface of the longitudinal beam, and at least one shackle retainer on each of the two narrow sides. an element is provided remote from said sliding surface, at least one shackle is provided extending transversely to said sliding surface defined by a longitudinal axis, each of the two lateral arms of said shackle comprising:
A plurality of side wall elements are detachably held by the one holding element, and are made of a flexible material and are arranged on two longitudinal beams on the side of the carrying part, and the side wall elements on both sides are attached to the side of the cargo part. 1. A backpack frame, which can be connected on the carrier side in the same manner as in the above, and wherein the coupling ring is composed of a male insertion portion and a female coupling sheath.

achieved by.

The present invention provides a backpack frame in which a three-dimensional arrangement of four longitudinal beams forms a hollow space that accommodates normal support belt tensioning and accessory equipment, but does not accommodate cargo. This means that the width of the narrow sides is small, resulting in a good wearing sensation for the user. When used as a backpack, the load area is located outside the sliding surface and its volume is variable. Since the arrangement of the retaining elements can take any form desired at this location, the shackle is arranged one above the other with the retaining elements attached to the narrow side, whereby the plurality of retaining elements are arranged one above the other. The shackle is height adjustable. And two or more shackles can be arranged one above the other. The sliding surface required when the device is used as a sled has not been eliminated so that the sled has very good sliding properties. In this device, a single backpack frame can be used as one small, independent sled, and two
Two backpack frames can be arranged in a mirror image relationship one behind the other for use as a larger transport or rescue sled. When the backpack frame is used as a backpack, the load is fixed to the load side; when it is used as a carrier or as a stretcher, the load or person to be transported is fixed to the load side by means of flexible side wall elements. , in which case also the variable-volume loading area is located substantially outside the hollow space formed by the longitudinal beams. Since, of course, a plurality of holding elements are provided which are not covered by side wall elements, it is advantageous for several side wall elements to be arranged one above the other on each longitudinal beam on the carrier side.

This allows the covering length of each pair of side wall elements to be adapted to the size of the load or person required in this respect. In the case of particularly awkward shapes of lead roofing sheets, the opposing sidewall elements are stapled together and then seamed together.

When used as a backpack and a sled, it is advantageous if the longitudinal beams on the carrier side have a greater mutual distance than the longitudinal beams on the load side, since this results in a trough-like configuration.

In one preferred embodiment, the upper end of each load side longitudinal beam is curved from the sliding surface towards the carrier side, and the curved ends are connected by a distal side beam.

The spatial structure of the longitudinal beams with retaining elements on the narrow sides and, in a preferred embodiment, the sliding plate arranged between the load side longitudinal beams makes the device particularly suitable for roads. makes it very easy to use as a sled in rough terrain. It is advantageous for elastic and flexible plastic sliding plates to form the reinforced edge sliding part of the longitudinal beam on the load side, as this provides directional stability on steep slopes. . In order to prevent excessive ingress of snow into the loading area on the carrier side, it is envisaged that the skids will be curved upwards on the narrow sides of the backpack frame.
In this respect, a plurality of openings are left on the narrow side, and a plurality of handholds are formed on the longitudinal beam on the carrier side.

In a further embodiment, the sliding plate has, on its narrow side on the coupling side, an obliquely raised strip which projects freely between the two cross beams, and on its opposite width. It is fixed to the cross beam at the narrow side. As a result, when the two backpack frames are connected by means of a coupling, the lifting edge strips abut against each other, so that it is no longer necessary to provide a connecting device on the sliding plate. The contact point is thus curved upwards and is formed at the position of maximum ground clearance, where it has the least influence on the sliding properties.

Since the backpack frame according to the invention can also be used for military purposes, in this embodiment:
Primarily in the form of skids, they can also be constructed to be anti-bullet and anti-fragment with fabric inserts such as those used in military helmets.

The plastic sliding plate can have a sufficient thickness so that the longitudinal beam on the load side can be embedded in its edge area and act as a reinforcing element. Although this sliding board is extremely light in weight, it is extremely strong.
For example, it is made of a laminate of an outer layer of thermosetting plastic reinforced with glass fibers cured by ultraviolet irradiation and an inner layer of urethane foam. As a variant of this, the skid plate can also be provided with anti-bullet and anti-fragment properties by means of a woven insert.

Preferably, each holding element is formed in the region of the cross beam that connects the carrier side longitudinal beam and the load side longitudinal beam at the narrow side. In this regard, in one preferred embodiment, each retaining element is formed by a hollow cross beam joining two longitudinal beams, which cross beams are inclined upwardly towards the load side, and the hollow cross beams are It has an insertion opening on the load side, in which each end of the shackle forms a projecting part which is inserted into the holding element. When the device is used as a shuttlecock, this construction makes it possible to dispense with special fastening means to the shackle. It is preferable that the upward inclination angle with respect to the side of the cross beam loading section is approximately 10° from the horizontal.

For use as a sled, the shackle is removed from the load side and inserted into its head so as to form a grip for pulling the sled. For this,
For example, a ski stock is attached to a shoe or carrier frame by a webbing or belt. If the upper ends of the load side longitudinal beams have openings, and these ends, the transverse beams and the insertion projections of the shackle are in the same spatial arrangement with respect to each other, for example if they diverge only slightly, then the pulling handshake will not be possible. A push-in connection can be achieved.

In a further embodiment, the two load side longitudinal beams have a support element as a holding element for at least one shackle, which shackle projects across the load side longitudinal beams and has a support element as a holding element for at least one shackle. will be installed on the

However, in that case, each of the supporting members is
It is formed by a V-shaped curvature of the carrier side longitudinal beam extending toward the load side, and the curved area is supported by the cross beam on the adjacent load side longitudinal beam. A particularly suitable shackle for this purpose is one with a U-shaped end hook that is inclined upwardly relative to the vertical sliding plate. When used as a sled, the shackle of this embodiment is attached to the front end of the longitudinal beam on the carrier side.

In both of the above-described embodiments of the shackle, the two lateral arms of the shackle are provided with coupling members or transverse members that abut against the load side longitudinal beams or slide plates.

Flexibility is particularly important when sidewall elements made of textile materials are of overlapping construction, for example to form a covering, and have belts, webbing, buckles and other commonly used connecting elements. There is. If at least one of the sidewall elements of each pair facing each other has a folded extension and a free edge strip of said extension, and the longitudinal strips adjacent to the folded edges are connected If the elements form structured overlapping connection areas, the circumference of the cover can be adapted to a considerable extent to the load. In this case, Velcro strips are particularly suitable as these connecting elements.

Preferably, the covering lengths of the side wall elements are such that they overlap each other in order to immobilize the casualty so that when the casualty is transported, these overlaps form at least partially a double wall. . This additionally forms thermal insulation which is very pleasing.

A preferred embodiment of two backpack frames arranged lower end to lower end in series is such that the lower ends of the two longitudinal beams of each narrow side terminate in a common coupling, the coupling being On one narrow side is a female coupling sleeve.
A male insert is formed on the other narrow side to be inserted into the female coupling sleeve, thereby providing for a tensile connection of the coupling part.

The device does not require additional coupling elements in the connecting part since the carrying strap part must have a connecting element such as a buckle or the like. If the device is used as a sled, no additional coupling elements are necessary.

In this way, two or twice as many backpack frames are arranged adjacent to each other and connected. The carrying strap portion used in the tensile connection may pass through the coupling members if both coupling members have a tubular form and both longitudinal beams terminate in recesses formed on their outsides. be able to.

These coupling elements have very little resistance to slipping if the end of each longitudinal beam on the load side, which terminates in the coupling, is inclined towards the carrier.

If two backpack frames are inserted into each other as a transport or rescue sled, care must be taken to ensure that no snow enters the loading area at the contact points of the skids. For this purpose, it is envisaged that in each embodiment with a sliding plate made of elastic plastic, the free edge section of the sliding plate should be half as large as the insertion length of the insertion part. The two free edge pieces raised diagonally opposite each other are more elastically curved in the completed state of this connection, and so that an effective seal exists at the point of contact and even if the tension resistance They are pressed together so that even if the connections loosen slightly during use, they remain sealed.

Instead of using belts or straps to connect the coupling members, it would be more advantageous if these coupling members could be inserted directly into the clasp. For this purpose, in a preferred embodiment, the male insert forms an inverted hook;
The cutlet-shaped cutlet spring sleeve has a crosspiece,
These inverted hooks are locked to this crosspiece, and the inverted hooks of the male insert in the catch expand the two spring tabs from the opening opposite the push-in side of the female coupling sleeve. can be removed from the crosspiece using a stick or fingers.

Another possible means for obtaining an immediate locking effect is, for example, at least one fixing pin mounted in a resilient manner on the side wall of the male mold insert,
One female coupling sleeve per fixed pin
This is implemented by having each hole 22 corresponding thereto.

〔Example〕

The backpack frame 1 has four longitudinal beams 3, 4 in a spatial arrangement defined by the edges of one prism with the basic shape of a trapezoid (see FIGS. 3 and 11). The longitudinal beams 3 on the carrying section side are arranged at a greater distance from each other than the longitudinal beams 4 on the loading section side. There is a cross beam 13 between the longitudinal beams 3 on the side of each carrying section and the longitudinal beams 4 on the loading section side, and the longitudinal beams 4 on the loading section side are connected to each other by a horizontal bar 10. The two longitudinal beams 4 on the load side have on one side an edge slide running along the edge of the longitudinal beam (see FIG. 5) and/or an edge reinforcing member (see FIG. 5, FIG. 11). ), which are preferably made of plastic and which additionally have guide ribs, i.e. central runners or the like in their central part (these are not shown). (not). The front end cross section of the longitudinal beam 4 and the front portions of the sliding plates 5a, 5b on the loading section side are curved toward the carrying section side. The longitudinal beams 3 and 4 are coupled with coupling rings 17 and 1.
8, these couplings can be used to connect two backpack frames 1, as shown in FIG.

In the embodiment shown in FIGS. 1 to 7, the carrier side longitudinal beam 3, which is preferably made of an aluminum metal tube of circular cross section, has a plurality of retaining elements 6a for the shackle 7. are doing. These holding elements 6a each hold the longitudinal beam 4 on the load side.
It consists of a hollow cross-beam 13 welded to the outside, thereby forming a receiving opening 28 (FIG. 2) which is inclined upwardly towards the load side.

Due to this arrangement of the longitudinal beams, the carrying belt 31 shown in broken lines in FIG.
Recesses or recesses are provided in which the (shoulder and waist belts) are arranged to be carried and tightened in the usual manner. Furthermore, between the longitudinal beams 3 and 3 on the side of the carrier, there is a support net 29 that can be adjusted and expanded in order to increase the ease of carrying (Fig. 3) and the safety against accidents (Fig. 5). Something similar to this will be installed.

The shackle 7 is inserted into a socket opening 28 in the hollow cross beam 13 (FIG. 3). Furthermore, it is also conceivable to arrange a plurality of shackle 7 in upper and lower stages.
Each shackle 7 is essentially U-shaped and its side arms are curved towards each other to form suitable parallel inserts 30 at their ends, and these shackle 7
The length of the parallel insertion portion 30 approximately corresponds to the length of the cross beam 13. Additional cross members 14 connect the side arms of the shaft. When this device is used as a backpack, the two parallel insertion portions 30 of the backpack 7 are
It is inserted into the cross beams 13 facing each other at the desired height, and then the cross member 14 is placed on the longitudinal beam 4 on the load side and thus on the outside of the slide plate 5a. Therefore, the central portion of each shackle 7 projects toward the cargo area. In this state, the load (FIGS. 2 and 3) is placed on the protruding part of the shackle 7 forming the floor. Side wall elements 9, clearly shown in broken lines in FIGS. 1 and 2, are provided for securing this load. These side wall elements 9 are
constructed of flexible material, such as canvas or similar strong and weather-resistant material, and folded at one end to form a sleeve or curve, otherwise detachable by means of webbing or clasps. Attached to the ceremony. The connections between the side wall elements 9 are likewise implemented, for example by straps and clasps. Retaining element 6
Each part of the longitudinal beam 3 on the side adjacent to the carrier receives a movable side wall element 9, ie the part of the longitudinal beam 3 which passes through the ring of side wall elements 9 is used as a pivot axis for the side wall element 9. In this way, the side wall elements 9 are closed in pairs, either on the load side or on the carrier side, so as to form a covering element (FIGS. 3 and 5). It is preferred to provide four side wall elements 9 for each longitudinal beam 3, of which two
A set is shown in FIGS. 1 and 2.

The sliding plate 5, whose upper end is bent down toward the carrier section, extends above the head of the carrier. The sidewall element is divided into three or four sidewall elements 9, so that even in very different conditions and with various levels of loading, or if the loading is disassembled into several parts, it is possible to transport several shackles. 7, the degree of overlap of each individual pair of side wall elements 9 can be varied so that they can be securely and tightly fixed to each cover part. Similarly, if cargoes with irregular contours are to be transported, a reliable connection of side wall elements 9 of different heights can be carried out.

Once the shackle 7 has been removed, the backpack frame 1 can be used as a sled, for example for ground transportation of loads, without any modification to the device. In this regard, the side wall elements 9 are used to secure the load with the same connecting elements (FIG. 5).

Additional advantages of the basic design become apparent when the device is used as a sled. Since the sliding plate 5 forms a completely enclosed sliding surface and the shackle 7 is attached to the narrow sides, there are no parts extending outwardly beyond the sliding surface. As shown in FIG. 4, the already removed shackle 7 is reinserted into the front end of the backpack frame 1 and fixed in place with a strap or the like.
Used as a towing shackle. The raised ends of the plastic sliding plates 5 reduce the sliding resistance on either side.

The central region of the slide plate 5 between the longitudinal beams 4 on the load side is slightly curved upwards, so that the edge slide provides great directional stability. Two backpack frames 1 are joined to form a large transport sled (FIG. 4), since it is possible to transport injured persons or to form a sled. This bond consists of two
made by two couplings (6th and 7th
figure). Each backpack frame 1 has a female coupling sheath 18 on one side and a male insert 17 on the other side, these couplings being such that the two backpack frames 1 are assembled in mirror image relation to each other. so that when the two devices are coupled, these couplings alternately engage each other.

In cross section, both coupling elements have an approximately rectangular cross section and have lateral recesses 25, 26;
The two ends of the two longitudinal beams 3, 4 are inserted therein. The male insert 17 is also arranged within the female coupling sleeve 18 so that a tension-resistant coupling 33 can extend across this coupling element. This tensile coupling coupling 33 can be accomplished by a webbing or part of a carrying strap, but if carrying straps or the like are not required, when the device is used as a sled, it may be necessary to It is preferred to use self-locking coupling means as shown in FIGS.

In this embodiment, in particular, a sliding plate 5 of flexible, elastic material is used, which sliding plate 5 has, on the coupling side, an edge strip 24 extending freely and obliquely between the two cross beams 10. The edge strip 24 projects into the distal half of the coupling element. When the two backpack frames 1 are fitted together, the two edge strips 24 of the two sliding plates 5
collide with each other and curve upward, so
This provides a substantially rigid bond and furthermore prevents snow from penetrating into the transport area.

As shown in FIG. This is because since it is fixed, it somewhat conforms to the body, and at the same time serves as a heating cover. Each negative frame 1 is provided with at least one shackle 7 so that a tow or support bar is formed at both ends, the shackle 7 being an opening in the raised end of the longitudinal beam 4 on the load side. inserted within. In this case also, the connection 32 is carried out by a belt, band, strap or the like which surrounds the end crossbar 10 of the backpack frame 1 and the crosspiece 14 of the shell 7.
The ski stock can then be attached, for example, to a tow or support rod so as to form a rescue sled when skiing.

Support net 2 for transport with the bed side on the back.
9 (FIGS. 3 and 5), it is also formed by an adjustable section of the carrier strip 31. Sliding on snow is only slightly weakened by the contact point, the coupling. This is because the contact points do not lie within the sliding surface.

The bed surface can also be provided with continuous padding or fluffing material.
On the narrow side of the backpack frame 1, the sliding plate 5
is preferably lifted and fixed to the longitudinal beam 3 on the carrier side. Parallel insertion part 3 for shaft 7
A socket opening 28 of 0 is formed in the raised narrow side 34 of this opening 28 at the location of the cross beam 13, and in addition a handle 27 is provided, by means of which the two backpack carrier frames 1 connected together can be attached to a stretcher. It can be handled relatively easily when used as a In addition, the part of the carrying band material 31 is
can be passed through and attached to the longitudinal beam 3 on the carrier side, but it can also be provided with eyelets, so that four carrier strips of this type can be attached to Can be hung from a wire hook.

In a second variant of the invention shown in FIGS. 8 to 13, the sliding plate 5b is made of plastic, preferably of reinforced laminated construction, and the longitudinal beam 4 on the load side are embedded in the longitudinal edge of the sliding plate 5b. The front portion of the sliding plate 5b is curved upward toward the carrying portion like the tip of a ski. The rear end or lower end of the longitudinal beam 4 on the loading side is curved toward the carrying section, which also means that the longitudinal beams 3, 4 on the carrying section and loading section end in coupling rings 17, 18. It means that. The sliding plate 5b is also curved in the coupling area to match the longitudinal beam 4.

The longitudinal beam 3 on the carrier side comprises a plurality of members 6b formed by a V-shaped curvature on the load side, in which each curved area is directly supported by one of the cross beams 13. has been done. The support elements 6b formed by these V-shaped curvatures serve as holding elements for one or more shackle 7b. Each shackle 7b is essentially U-shaped and at its connection the side arms are inclined upwardly with respect to the sliding plate 5b and are caused to form a terminal hook 8 at the free end of the shackle. The horizontal member 14 is provided at the curved part of the side arm of the shaft, and is placed on the longitudinal beam 4 on the cargo side, and the longitudinal beam 4 is fitted into the sliding plate 5b, so that it does not slip. It is placed on the outside of the plate 5b.

In the overlapping connection part 15 the side wall element 9 is provided with a Velcro strip and has a plurality of closing pieces 19 in order to provide two dimensional changes to the closure in its connection, the two connection parts 15 being overlapped. The Velcro strips 19 are rotated through 90° relative to each other. (In FIG. 10, the Velcro strip 19 of the left side wall element 9 is of course provided on the inside).

As shown in FIG. 10, the deformed structure of the left side wall element 9 with the inwardly folded extension 16 is
Suitable for use with oversized cargo. The overlapping connecting part 15 is thus provided adjacent to the folding line on the side of the inwardly folded extension 16 and adjacent to the further connecting part 1
5b must be provided on the free edge of the extension 16 on the side facing the side wall element 9 if an oversized load is to be wrapped as shown in FIG. Therefore, in order to fix the folded extension part 16, attaching the Velcro strip 19 to the inside of the left side wall part 9 in FIG. This is the best as it is provided. Of course, the right-hand side wall element 9 can also have an extension 16 and an additional extension 16 folded back onto both side wall elements 9.
It is also possible to provide When used as a sled, the sidewall elements 9 are arranged with the overlap reversed, i.e. the overlapped sidewall elements 9 shown in FIG.
It can be closed with the outside facing inside.

As already mentioned, the end-lifting slide plate 5b is preferably constructed of a laminate of fibre-reinforced plastic and, in the case of military purposes, is provided with a separate additional insert to make it resistant to bullets and fragments. This is particularly preferred since the distal end of the slide plate 5a is curved forward to provide head cover when used in backpack form. Thus, for example, the skid can be wrapped with an outer layer of glass fiber reinforced thermoset plastic with a core of polyurethane foam.

Figures 12 and 13 show a first embodiment of a self-locking coupling. The female coupling sleeve 18 has a substantially rectangular cross section;
At this connection, the ends of both longitudinal beams 3, 4 are
It is inserted into the female coupling sleeve on the carrier side. A hole 22 is formed in each narrow side.
The male insert part 17 with the two longitudinal beams 3, 4 at the other end has a covered space 23 in which U-shaped springs 20 are arranged, these springs has fixing pins 21 projecting outward at both ends thereof. When inserting, insert the fixing pin 21 into the hole 22.
This completes the connection of the two backpack frames 1. By pressing on the fixing pin 21 these two assemblies can be separated very easily.

14 to 19 show a second embodiment of the self-locking coupling. The male insert 17 and the female coupling sleeve 18 essentially correspond to the coupling elements used in the embodiments shown in FIGS. 1 to 7, i.e. both have a sleeve configuration and a longitudinal beam. 3,4
It has lateral recesses 25, 26 into which the ends of the two are inserted.
A crosspiece 35 is formed approximately in the center of the female coupling sleeve 18, which connects with spring-acting side elements 36. On the side of the female coupling sleeve 18 which is connected to the longitudinal beams 3, 4, the lateral elements 36 of the spring project from its side walls 40. Crosspiece 3
5 are held by inverted hooks 39 when the male insert 17 is inserted into the female coupling sleeve (FIG. 18), these inverted hooks 39 having spring tabs 38 at their ends. The spring tab 38 extends along the entire length of the male insert 17 and projects from the crossbar 37, which is connected to the longitudinal beams 3, 4 on the side of the male insert 17 and to the side walls 41 thereof.

Since the female coupling sleeve 18 is also open on the carrier side, the spring tab 38 in the detented state is also expanded from the open side.
This connection is released again. Furthermore, the spring tab 38 with reverse hook 39 is free from undesired expansion; for example, a cap, slide, etc. (not shown) may be provided to prevent the spring tab from returning. It is attached to a male insert 17 or a female coupling sleeve 18 for the purpose of making the coupling.

〔Effect of the invention〕

Therefore, the backpack frame 1 according to the present invention is a multifunctional device that can be combined as described above, and this structure allows it to be used for its individual functions (as a backpack, or as a sled with an additional belt attached). The stretcher (stretcher) is now better adapted than ever before, with excellent carrying ease and safety due to the hollow space, adjustment of the height of the load due to the shackle and its holding elements and side wall elements, stability, safety and ease of use when used on a sled. The arrangement of the sliding plates provides excellent directional stability of sliding, cargo protection, versatility of the sliding plates, and excellent traction ability, allowing it to function in a way that is close enough to a dedicated device for use in achieving a specific mission.
