Abstract

PURPOSE: To easily exchange a housing by constituting a self standing type structure unit and the housing composed of only a covering part. CONSTITUTION: A metal frame 1 for which strings are stretched is gathered with a resonance plate, supporting poles, a keyboard supporting body 2 and an accessory mechanism so as to be the self standing type structure unit 4 by a foot base 3 provided with a pedal supporting piece. The housing including side parts 5 is used only for covering. The side parts 5 or the like are attached to the structure unit 4 by simple connection 6 used generally in furniture manufacture. Thus, the structure unit 4 is used without change to the upright piano of different appearance and the covering part for forming the housing is easily matched with the desire of a customer. Also, the expenses of a fund and inventory are reduced.

Description

[Detailed description of the invention]

0001

[Industrial Application Field] The present invention relates to a stringed metal frame,
This invention relates to a vertical piano having a soundboard, a soul pillar, a keyboard arranged on a support, an attached mechanism, and a housing.

0002

BACKGROUND OF THE INVENTION Traditionally, the main vertical piano or piano part was held by a housing, in particular by the piano side walls which also supported the keyboard support, and the inner part formed a structural unit with the housing or only the side parts. ing. A disadvantage of this construction style is that the housing cannot be replaced in order to adapt the housing profile and wood type to the customer's wishes. Rather, it is necessary to manufacture a new vertical piano according to this request or to stock a large number of vertical pianos with different external shapes.

It is also already known (US Pat. No. 4,941,63) to assemble the housing of a vertical piano from two mutually removable parts, in which case one part is assembled together with the keyboard support and the pedal support piece. The front part forms the front part, and the other part, together with the rear wall and the housing lid, constitutes a complement to the side walls, but nothing is said about the stringed frame, and it is not possible to disassemble the housing. , the only purpose is to make it easier to transport a vertical piano.

0004

The problem underlying the invention is to eliminate these drawbacks and to provide a vertical piano whose housing can be easily replaced.

[0005]

[Means for Solving the Problem] According to the present invention, this problem is achieved by providing a metal frame that supports the soundboard, the soul pillar, and the keyboard so as to be a self-supporting structural unit by means of a footrest having a pedal support piece. body and mechanism, and the housing consists only of covering parts, which are easily removably attached to the structural unit or can be connected to each other in a known manner. .

[0006]

[Effects of the Invention] The structural unit can be used without modification for vertical pianos with different external appearances, and it is only necessary to adapt the covered part forming the housing to the customer's wishes like furniture, and the external appearance These different coated parts can be grouped together, suitably packaged and stocked. As a result, capital or inventory expenses are significantly reduced for the manufacturer or seller who is able to offer a maximum supply of vertical pianos with different appearances. Since the piano can be transported not only as a structural unit, but also without the covering part forming the housing, transporting the piano becomes much easier.

[0007] In order to removably attach the housing part to the structural unit, it is preferable to use a simple coupling commonly used in furniture manufacturing, one part of which is attached to the structural unit; The other part is initially attached to the covering part and can be inserted into each other, and by twisting the simple coupling, the respective structural parts are fastened together via the threaded surfaces. To connect the footrest, which also forms the keyboard support, to the metal frame, screws are generally conceivable, but any other connection method is also conceivable.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The invention will now be described with reference to embodiments shown in the drawings.

The stringed metal frame 1 forms a keyboard support 2 and has a footrest 3 with a pedal support piece (not shown).
are assembled to form a self-supporting structural body 4. The housing, of which only the side parts 5 are shown, is used only for covering purposes. These lateral parts 5 are
In furniture manufacturing, the structural unit 4 is assembled by a simple joint 6 that is common in furniture manufacturing.
The same also applies to other covering parts if they are not connected to the side parts 5 in the usual way.

[Brief explanation of the drawing]
