Abstract

A wheelchair table includes: an attachment part configured to be attached to a side part of a wheelchair; an arm supported by the attachment part; and a table body provided at a tip part of the arm. The arm is supported so as to be movable upward and downward relative to the attachment part such that the table body can be lowered from an in-use position located above a user'"'"'s knees to a not in-use position located in front of and below the knees while the user sits in the wheelchair. With this wheelchair table, operability and safety during wheelchair travel can be enhanced while favorably maintaining the function as a table.

Claims

1. A wheelchair table comprising:

an attachment part configured to be attached to a side part of a wheelchair;

an arm supported by the attachment part; and

a table body provided at a tip part of the arm;

wherein the arm is supported so as to be rotatable in upward and downward directions relative to the attachment part such that the table body can be lowered from at least one in-use position located above a user'"'"'s knees to a not in-use position located in front of and below the knees while the user sits in the wheelchair;

wherein the arm includes

a latch part configured to engage an engagement part of the attachment part,

a spring configured to bias the latch part to engage with the engagement part, and

a lever configured to detach the latch part against a biasing force of the spring;

wherein the arm is configured to rotate relative to the attachment part when the lever is rotated by applying a pushing force to the lever to counter the engagement between the engagement part and the latch part; and

wherein a direction of rotation of the lever matches a rotational direction of the arm.

2. The wheelchair table according to claim 1, wherein the arm further comprises:

a framework configured to rotatably support the lever, the lever including a handle within the framework.

3. The wheelchair table according to claim 1, further comprising:
