Transportation device for a musical instrument
The transportation device for a musical instrument, preferably for a cello, is made to fit over a conventional everyday case which is made of a hard material and which is provided with hinges. There is provided a protective cover for the everyday case which is adapted to the shape of the everyday case, is impact resistant and is completely surrounding the everyday case, when the everyday case is placed therein. The protective cover is inflatable and deflatable, and it is surrounded by an outside cover made of a puncture-proof and flexible fabric. The protective cover and the outside cover are attached to each other. Both covers are light-weight compared to the everyday case.
The invention refers to a transportation device for a musical instrument, preferably for a cello, intended to be used in conjunction with and to fit over and around a conventional everyday case made of a hard material, which is provided with hinges and whose interior is intended for the admission of the musical instrument.
BACKGROUND OF THE INVENTIONNowadays musicians, e.g., soloists and members of leading symphony orchestras, must travel frequently by air. To protect the instrument and its case during air transport, the secure packing of the instrument and its case requires special measures. It must be protected against external impact, such as sudden knocks, falls or drops, or abrasion on sharp corners, points, edges, and the like.
A particular risk is the flight itself. The musician delivers the instrument accommodated in a transport container (such as an everyday case) to the baggage check-in and receives it only upon arrival at the baggage claim. Unfortunately, serious damage can take place in transport, and sometimes the instrument is completely destroyed. The instrument in its container is treated improperly, it can be thrown from the airplane hold onto the baggage conveyancing system, or it can even be dropped from the airplane hold onto the tarmac from a height of several meters.
For everyday use, the musician ordinarily transports his instrument in an upholstered transport cover made from flexible material or in a hard shell case (“everyday case”). Such containers are absolutely suitable for daily use, where there is minimal risk from serious impact. These cases are advantageous because they are relatively lightweight. A hard-shell case for a cello weighs between 3 to 6 kg.
Under the name “flight case”, there are special hard shell-cases on the market which are offered for use on airline flights and are equipped with special features to prevent damage during flight transport. There is a hard shell case for a stringed instrument (Gill, D-91088 Bubenreuth) which is manufactured using fiber glass and contains an internal suspension fixture and velvet upholstery to help protect the instrument. Such a hard shell case possesses a weight of 9.5 kg for a cello and 23 kg for a double-bass.
Another available hard shell case (GEWA, D-82477 Mittenwald) employs a shell made from fiberglass-reinforced synthetic resin. An internal suspension fixture for the instrument is also provided. Another internal feature is foamed plastic upholstery for the back and ribs of the stringed instrument. Such hard shell cases for a double bass weigh 25 kg. So-called “flight cases” possess as a rule a weight considerably above that of the everyday case. This also accounts for the higher purchase price.
Nevertheless, insurance societies who provide insurance cover for musical instruments declare that hard shell cases, even if they are conceived and equipped for the rough conditions of flight transport, do not withstand occasional damage and therefore do not guarantee full protection.
Hence, a solution would be desirable which on the one hand offers full protection against destruction of the instrument during air transport, in particular as it relates to impact, and, on the other hand, is also relatively lightweight. The transportation device should dispense with the need for an additional and special flight container which is expensive to purchase, takes up considerable space, and is heavy to transport.
From the German patent application DE 100 38 467 A1 a foldable case from a soft, malleable material is designed for use with a musical instrument. The shape conforms to a typical musical instrument and is obtained here by inflating of inner tubes or aerial chambers located in the interior of the soft-case. These inner tubes or aerial chambers offer an additional protection for the musical instrument. It is to be stressed, however, that these inner tubes or aerial chambers are located in the interior of the soft-case. In the event of impact against a sharp object, the case might be punctured or pierced and with it the protecting inner tube, so that the air can escape. Such a soft-case is not planned for flight transportation and is designed especially for an acoustic guitar.
Another inflatable transportation device for a musical instrument is known from U.S. Pat. No. 4,215,778. This device comprises an inflatable bottom portion and an inflatable lid portion with a space in which the instrument is accommodated, completely encased by independently inflatable structures. In addition it must be stressed that a conventional everyday case is not used here.
A transportation device which comprises a conventional hard shell case (“everyday case”) and an external protective cover is offered for journeys by air and available on the market. (BAM, F-14160 Dives-sur-Mer). The protective cover consists of two halves made of an impact resistant and extremely strong, respectable material, which are adapted to the shape of the everyday case and which are connected with each other by a completely running around zipper. The inside of the protective cover is laid out with a thick layer from a foamed plastic of high density which protects the everyday case and the instrument against impact and thermal charges. The protective cover is provided with three handles and two backpack belts. The protective cover when conceived for a cello case weighs 8 kg. Its weight lies therefore above the weight of the everyday case which usually amounts to 3 to 6 kg.
Also it must be emphasized that such protective covers are sized for specified everyday cases. Nevertheless, a varied use with different everyday cases of different manufacturers would be desirable. In addition, the owner of the protective cover needs a considerable space for keeping and storing it when not in use. When in use while traveling certain difficulties can arise because of the size, weight and solidity, e.g., with accommodation in a normal sized taxi, while getting on and off a bus or a streetcar, or with the transport over an escalator.
OBJECTS OF THE INVENTIONIt is an object of the invention to provide a transportation device for a musical instrument made to fit over a conventional hard shell everyday case and comprising an external protective cover to increase the security, in particular concerning journeys by air.
It is another object of the invention to improve the handling and still to reduce the weight of the complete transportation device.
And it is still another object of the invention to design the protective cover is such a way that it can be folded and stored when not in use.
SUMMARY OF THE INVENTIONAccording to the invention, a transportation device is provided
-
- wherein a protective cover for the everyday case and the musical instrument contained therein is provided, wherein the protective cover is adapted to the shape of the everyday case, is impact resistant and is completely surrounding the everyday case, when the everyday case is placed therein,
- wherein a zipper is provided, when said zipper is open, the everyday case is easily accommodated within the protective cover and easily removable from the protective cover,
- wherein the protective cover is inflatable and deflatable,
- wherein the protective cover is surrounded by an outside cover made of a puncture-proof and flexible fabric,
- wherein the protective cover and the outside cover (are attached to each other, and
- wherein the protective cover together with the outside cover is light-weight compared to the everyday case.
Such a transportation device can be used with all kinds of musical instruments, thus, e.g., with stringed- and plucked instruments, woodwind and brass instruments. It offers by the use of at least one aerial chamber and the puncture-proof outside cover an effective protection against sudden knocks, falls or drops or other improper external treatment. The protective cover can be adapted to different or various contours of everyday cases and therefore can be used with everyday cases of different manufacturers.
In connection with the transportation device a carrying bag may be used which is constructed of a light synthetic fabric and in which the protective cover, surrounded by the outside cover, can be accommodated after removal from the everyday case and after being folded. In such a carrying bag the protective cover and the outside cover (with the air deflated) may easily be stored away when not in use during a trip or at home. Proper handling is guaranteed, e.g., while traveling by taxi, and the transport by hand causes no serious problems, because the weight of the protective cover with outside cover and carrying bag is relatively low and amounts to approximately 3 kg, while the everyday case itself weighs between 3 to 6 kg.
The protective cover and the outside cover may be connected with each other, e.g., by glueing or welding or by a Velcro closing. The outside cover should be waterproof or provided with a water-proof layer.
The protective cover may possess one or several aerial chambers. If several aerial chambers exist, e.g., 2 or 3 which contribute to an increased level of security, these chambers should each be inflatable independently from one another. Each of these aerial chambers may consist of a series of single segments or partial aerial chambers, for instance, in the form of tubes, and the segments of every series should be connected with each other in parallel. The segments of the individual series should be arranged alternately beside each other. It is for safety reasons that the segments of the different series are arranged alternately beside each other. The thickness of the inflatable protective cover should be between 5 to 10 cm when inflated.
Additional embodiments are described in the subclaims.
The foregoing and other objects, features and advantages of the invention will be apparent from the more particular description of preferred embodiments of the invention, as illustrated in the accompanying drawings. For identical elements, the same reference numerals will be used.
BRIEF DESCRIPTION OF THE DRAWINGS
According to
In the conventional manner, the everyday case 6 has two hinges 10 and a number of locks 12 located around the circumference. A handle 14 is arranged on the opposite side of the hinges 10.
The protective cover 4 is illustrated—for reasons of clarity—at some distance from the everyday case 6. In reality in its inflated condition it lies close to the everyday case 6. It is at least roughly adapted to the contour of the everyday case 6. Also the puncture-proof outside cover 8 is shown at some distance from the protective cover 4. In reality adjoins the protective cover 4. As a matter of preference, they will be attached to each other, e.g., by glueing or by welding.
In the embodiment of
In the inflated state these layers 16, 18 have a distance D to each other. This distance D characterizes the thickness of the inflated protective cover 4 and therefore the thickness of the protecting air cushion (air bladder). The thickness D should lie in the area of about 5 to 10 cm to guarantee an effective impact protection during air transportation. Given the flexibility of the material used for the protective cover 4, it can expand while inflating, thus the dimensions will change upon inflation. Then the pressure, measured by a pressure gauge (not shown), determines the thickness D.
As mentioned, the outside cover 8 is made of an adaptable and puncture-proof material. There may be a water-proof layer or water-proof finish. This material should be abrasion-resistant at the same time. As a suitable material, in particular a bullet-proof fabric, such as the one known under the name “Kevlar”, or another fabric called “Zylon” may be used. The protective cover 4, together with the outside cover 8, is light-weight in comparison to the weight of the everyday case 6.

In this particular design it comprises a first series 4A and a second series 4B of segments or partial air chambers 34, 36. All air chambers 34 of the first series 4A are connected with each other and are jointly inflatable as well as deflatable. Also the air chambers 36 of the second series 4B are connected with each other. They are also jointly inflatable and deflatable, but independently of those of the first series 4A. The air chambers 34, 36 are arranged alternately next to each other.
They can have the design of air tubes which have, e.g., been glued or welded together and possess—deviating from the representation in
The air can be supplied jointly to all air chambers 34 of the first series 4A via a first valve 38. The air can be deflated again via this same valve 38 before packing away the device 4, 8. The corresponding is true with regard to the air chambers 36 of the second series 4B and a second valve 40. Deviating from the representation, both valves 38, 40 should be placed well-protected, i.e. preferably underneath the surface of the outside cover 8.
Of course more than a first and second series 4A, 4B can be provided.
