A bag according to any one of claims 1 to 7 , The aforementioned rotating part is a grip part held by the user, which is a bag.
A bag according to any one of claims 1 to 8 , The wheel locking mechanism is The body and A rotating member is supported by the body so as to be rotatable around a rotation axis, has a recess formed on at least a portion of its outer circumferential surface around the rotation axis, and rotates together with the wheel, A linear body having a protrusion, connected to the control wire, configured such that when the control wire is in the first position, the protrusion does not engage with the recess, resulting in the unlocked state, and when the control wire is in the second position, the protrusion engages with the recess, resulting in the locked state; A bag that has a bag.
The bag according to claim 9 , A bag wherein the wheel locking mechanism is configured to transition from the locked state, in which the protrusion is fitted into the recess, to the unlocked state, as the linear body moves in a direction perpendicular to the rotation axis of the rotating member, thereby separating the protrusion from the recess.
A bag according to claim 9 or claim 10 , A plurality of recesses are formed in at least a portion of the outer circumferential surface of the rotating member. The linear body is a bag having a plurality of protrusions that can be fitted into each of the plurality of recesses.
The bag according to claim 11 , The linear body is a bag having a rack member on which a plurality of teeth that function as protrusions are formed.

Description

The technology disclosed herein relates to bags. Bags with a main body containing a compartment for storing luggage, a handle attached to the main body, and wheels attached to the bottom of the main body are widely used. In such bags, the user can move the bag while the wheels remain on the ground by gripping the handle and pulling it. Various bags have been proposed that have a wheel locking mechanism capable of restricting (locking) the rotation of the wheels to prevent unintended movement of the bag. Patent Document 1 discloses a bag in which the wheel locking mechanism has an electric actuator capable of restricting the rotation of the wheels, a button switch for operating the electric actuator is provided on the handle, and when an operation signal generated by the button switch is transmitted wirelessly to the wheel locking mechanism, the electric actuator restricts the rotation of the wheels.

A. Embodiments: A-1. Bag composition: Figures 1 and 2 are schematic diagrams illustrating the configuration of the bag in this embodiment. The bag 10 is a so-called suitcase and has a handle 200. Figure 1 shows the external configuration of the bag 10 with the handle 200 retracted, and Figure 2 shows the external configuration of the bag 10 with the handle 200 extended. Each figure shows mutually orthogonal X, Y, and Z axes. Hereafter, the positive Z-axis direction will be referred to as the upward direction, and the negative Z-axis direction will be referred to as the downward direction. In each figure, some components are shown transparently, and some components are omitted from the illustration. These points are also the same for Figures 3 and beyond. The bag 10 comprises a bag body 11, a handle 200, two casters 100, each containing a wheel 120, and a wheel locking mechanism 20. The wheel locking mechanism 20 switches between an unlocked state, allowing rotation of each wheel 120, and a locked state, restricting rotation of each wheel 120. Hereinafter, the surface of the bag 10 viewed from the positive Z-axis direction will be referred to as the top surface, the surface viewed from the negative Z-axis direction will be referred to as the bottom surface, the surface viewed from the positive Y-axis direction will be referred to as the front, the surface viewed from the negative Y-axis direction will be referred to as the back, and the surfaces viewed from the positive and negative X-axis directions will be referred to as the sides. The bag 10 will be described assuming that the handle 200 extends vertically (in the Z-axis direction), but the bag 10 can assume other orientations. The bag body 11 is a box-shaped structure with a space for storing luggage, and is, for example, a roughly rectangular parallelepiped. A lid 12 that can be opened and closed is provided on the front of the bag body 11. In Figures 1 and 2, the lid 12 is shown with a dashed line for convenience. The handle 200 is the part that the user grips when lifting or moving the bag 10, and is attached to the back side of the bag body 11 at approximately the center along the X-axis. The handle 200 has two pole sections 290 and a handle body section 210. Each pole section 290 is, for example, roughly rectangular in shape and is attached to the bag body 11 in a position that extends vertically. Each pole section 290 has a telescopic mechanism 292 that extends and retracts along the vertical direction. The telescopic mechanism 292 is configured to switch between a s
