Abstract

A stand includes a lateral spanning member, a connecting member configured to be fixed to the lateral spanning member and having a first engagement portion and a second engagement portion, and a front leg comprising a first engagement target portion configured to be brought into engagement with the first engagement portion and a back leg comprising a second engagement target portion configured to be brought into engagement with the second engagement portion, and a first engagement construction in which the first engagement target portion is brought into engagement with the first t engagement portion and a second engagement construction in which the second engagement target portion is brought into engagement with the second engagement portion are different from each other.

First claim

What is claimed is:

1 . A stand comprising:
a lateral spanning member a connecting member configured to be fixed to the lateral spanning member and having a first engagement portion and a second engagement portion; and a front leg comprising a first engagement target portion configured to be brought into engagement with the first engagement portion and a back leg comprising a second engagement target portion configured to be brought into engagement with the second engagement portion, wherein a first engagement assembly in which the first engagement target portion is brought into engagement with the first engagement portion and a second engagement assembly in which the second engagement target portion is brought into engagement with the second engagement portion are different from each other.

2 . The stand according to claim 1 , comprising:
a brace configured to fit between the front leg and the back leg and span a space defined therebetween.

3 . The stand according to claim 1 ,
wherein a leg adjustment member is provided on at least one of a bottom surface of the front leg and a bottom surface of the back leg.

4 . The stand according to claim 1 ,
wherein the front leg comprises a first internally threaded portion, and the back leg comprises a second internally threaded portion, wherein the connecting member comprises a first hole portion in which a first screw configured to be screwed into the first internally threaded portion is inserted and a second hole portion in which a second screw configured to be screwed into the second internally threaded portion is inserted, and wherein a height of the first internally threaded portion from a setting surface and a height of the second internally threaded portion from the setting surface are different from each other.

5 . The stand according to claim 1 ,
wherein the front leg comprises a first externally threaded portion, and the back leg comprises a second externally threaded portion, wherein the connecting member comprises a first hole portion in which the first externally threaded portion is configured to be inserted and a second hole portion in which the second externally threaded portion is configured to be inserted, and wherein a height of the first externally threaded portion from a setting surface and a height of the second externally threaded portion from the setting surface are different from each other.

6 . The stand according to claim 1 ,
wherein the front leg and the back leg each comprise an upper leg attachment surface and a lower leg attachment surface, and wherein the connecting member comprises an upper leg attachment portion to which the upper leg attachment surface is configured to be fixed and an extended portion extended from the upper leg attachment portion and to which the lower leg attachment surface is configured to be fixed.

7 . The stand according to claim 6 ,
wherein in one of the front leg and the back leg, a direction of a normal of an attachment surface of the upper leg attachment portion and a direction of a normal of an attachment surface of the extended portion are different from each other.

8 . The stand according to claim 1 ,
wherein the connecting member comprises a left connecting member configured to be fixed to a left side of the lateral spanning member and a right connecting member configured to be fixed to a right side of the lateral spanning member.

9 . The stand according to claim 8 ,
wherein the front leg and the back leg each comprise an upper leg attachment surface and a lower leg attachment surface, wherein one of the left connecting member and the right connecting member comprises a front upper leg attachment portion to which the upper leg attachment surface of the front leg is configured to be fixed, a front extended portion to which the lower leg attachment surface of the front leg is configured to be fixed, a back upper leg attachment surface to which the upper leg attachment surface of the back leg is configured to be fixed, and a back extended portion to which the lower leg attachment surface of the back leg is configured to be fixed, and wherein directions of normals of attachment surfaces of the front upper leg attachment portion, the front extended portion, the back upper leg attachment portion, and the back extended portion are different from one another.

10 . The stand according to claim 1 ,
wherein the connecting member comprises a first indicator portion which is a mark for assisting proper engagement of the first engagement target portion with the first engagement portion, and a second indicator portion which is a mark for assisting proper engagement of the second engagement target portion with the second engagement portion, the first indicator portion being different from the second indicator portion such that the first indicator portion and the second indicator portion can be discriminated from each other.

11 . The stand according to claim 1 ,
wherein a leg comprising the front leg and the back leg comprises a first leg, a second leg, and two third legs having an identical configuration.

12 . A keyboard instrument set comprising:
the stand according to claim 1 ; and a keyboard instrument configured to be attached to the stand.

13 . The stand according to claim 10 ,
