BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a musical instrument support rack for a drum set.

[0002]

2. Description of the Related Art A drum set is composed of a bass drum, a tom tom, a floor tom, a snare drum, a cymbal and a hi-hat cymbal.

When setting this drum set on a performance stage, conventionally, a bass drum is laid horizontally on the stage, a tom holder is mounted on the bass drum to support the tom tom, and the floor tom is used for supporting the tom tom. A trunk is attached to the torso and installed on the stage. Further, each of the snare drums and cymbals has a stand having a tripod type leg portion which stands on the stage and is supported by the stand.

However, if all the stands for snare drums and cymbals are set up on the stage in this way, the larger the number of musical instruments, the more stands stand on the stage. However, there is no foothold. For this reason, recently, it has been considered to install an instrument support rack on the stage and support some instruments on the rack without using a stand.

As this musical instrument support rack, the one described in the specification and drawings of Japanese Utility Model Application No. 57-149220 has been conventionally known. This instrument support rack has 1
A rack frame composed of a front beam member and two left and right side beam members connected to both ends of the front beam member, a pedestal for supporting the rack frame, and a detachable member that can be attached to any position of the rack frame. A plurality of musical instrument supporting pipe holders.

The front beam member and the side beam member of the rack frame are made of square pipes, and bent portions extending at right angles behind the front beam member are formed at both ends of the front beam member. There is. In addition, the left and right side beams are both straight beams, and each side beam is pivotally attached at one end to the tip of the bent portion of the front beam with a pin to It is connected so that it can be folded. The pedestals are provided at four positions, that is, both end portions of the front beam member and outer end portions of the side beam members, and the upper ends of the pedestals project from the lower surface of each beam member. It is detachably screwed to the bracket.

Further, the pipe holder is fitted to the outside of the beam member of the rack frame and screwed to the beam member, and the lower pipe of the musical instrument support arm is held and fixed to the pipe holder. A pipe holder is provided.

This musical instrument support rack is used in a state where the rack frame is expanded into a shape, and the rack frame is horizontally supported above the stage by pedestals provided at four positions thereof. Of the various musical instruments that make up the drum set, floor-standing type musical instruments such as bass drums are placed on the stage, and some musical instruments among other musical instruments have rack pipes on the lower pipes of their supporting arms. The pipe is attached to the pipe holder and is supported by the rack, and the rest of the musical instruments are set up on a stage.

Therefore, if the above-mentioned instrument support rack is used, some of the musical instruments that compose the drum set can be arranged without standing on the stage, so that the number of stands can be reduced and the number of stands can be reduced. You can set the drum set neatly.

By the way, the loading and unloading of the musical instrument support rack to and from the performance hall is carried out in a disassembled state in which the pipe holder is removed from the rack frame and the pedestals are removed from the rack frame. It is folded and transported. The rack frame is folded by first folding one side beam member on the rear surface of the front beam member and then folding the other side beam member on the outside thereof.

[0011]

However, the above-mentioned conventional musical instrument support rack has a problem that the rack frame is troublesome to carry. This is because even if the rack frame is folded, its size is reduced only to the width in which the beam members (the front beam member and the left and right side beam members) that form the rack frame are overlapped. Since it is bulky and difficult to hold, and the weight of the rack frame is the total weight of the beam members, considerable effort is required to transport the rack frame.

Even in the conventional instrument support rack,
If you remove the pin connecting each beam from the rack frame,
The rack frame can be separated into individual beam members for easy transportation.

However, when the rack frame is separated into individual beam members in this way, when the rack is disassembled, the pedestals are removed from the rack frame, and the pins are removed from the rack frame to remove the rack frame from each beam member. Must be separated into
Disassembling the rack becomes complicated. This is the same when assembling the rack. In this case, the rack frame must be assembled by connecting the beam members with the above pins and the pedestal must be attached to the rack frame. Becomes complicated.

An object of the present invention is to enable separation and connection of each beam member constituting the rack frame by removing and attaching the pedestal, and the rack frame is separated into individual beam members for easy transportation. (EN) Provided is a musical instrument support rack for a drum set which can be easily disassembled and assembled.
