A retractable leash device (e.g., for pets, children, or the like) having a length control system for limiting the extendable length of a main line is provided. The device includes a cover plate mounted on a wind-up spool and having at least one ridged channel that interacts with a length control switch during line extension to control the extendable length of the main line while simultaneously maintaining the retractability of the main line.

The cord reel device includes a reel body provided with a rotation shaft, a housing that stores inside the reel body in a rotatable manner, and a cord which is wound around the reel body so as to be extractable and which is extracted to an outside through an opening of the housing. The reel body has disk-shaped members on a plane perpendicular to the rotation shaft, and the cord is stored in a space formed between the disk-shaped members. A guide section inclined relative to the rotation shaft of the reel body is provided around peripheries of the disk-shaped members of the reel body. While the cord is wound around the reel body, the guide section guides the cord to the rotation shaft of the reel body.

Apparatus for covering product containers loaded in a cargo container is disclosed. The apparatus includes an automated cord reel including a spool and a motor configured to drive the spool. The spool when activated reels in a cord attached to a cargo blanket to spread the cargo blanket over product containers in the cargo container in a smooth motion and/or relatively constant speed to prevent snagging on the product containers. The automated cord reel may be configured as a mobile unit with wheels. A brake system may be provided to prevent movement of the automated cord reel during operation. The automated cord reel may have a battery to provide electric power to the motor. A magnetic floor brake may be configured to hold a cart body in a selected position.

A reel holding device is provided. The device includes: a case which accommodates the plurality of component supply reels to be aligned in a direction of a reel axial line; outer circumferential support members which are built between two sides walls of the case, and support outer circumferences of the multiple component supply reels to be rotatable; and a deviation preventing member which prevents the component supply reels from deviating from the outer circumferential support members. At least one of the outer circumferential support members and the deviation preventing member is an integrated rod-like member which is built between the two side walls.

A protractible and retractable mast system for an autonomous mobile robot includes an elongate flexible member including a first lateral end and a second lateral end, and a fastener having a first portion extending along a length of the first lateral end and a second portion extending along a length of the second lateral end. The flexible member is configured to be at least partially coiled within a body of the robot, and a portion of the flexible member is vertically movable away from the body when the flexible member is being uncoiled. The fastener is configured to connect the first lateral end to the second lateral end when the flexible member is being uncoiled, and disconnect the first lateral end from the second lateral end when the flexible member is being coiled.

The present application provides a wiring harness device a display device. A wiring harness device applied to a wire connected between two interfaces comprises: a wiring harness structure having a first wire inlet and a first wire outlet, the wire entering the wiring harness structure through the first wire inlet and exiting the wiring harness structure through the first outlet, the wiring harness structure configured to store and provide the wire, the wire being controlled to be in a relaxed state upon provision through stretching the wire.

Disclosed is a shoelace folding and releasing device, comprising: a thread reel used for winding thread, a knob device in transmission connection with the thread reel, and a position limiting device and arresting disk arranged between the thread reel and the knob device. After the knob device is pressed, both the thread reel and the arresting disk are locked with the knob device. The arresting disk restricts the clockwise or counterclockwise rotation of the knob device, and the knob device drives the thread reel to rotate so as to tighten a shoelace. When the knob device is pulled out, both the thread reel and the arresting disk are unlocked from the knob device, and the thread reel releases the shoelace, and at the same time, the position limiting device restricts the separation of the knob device.

In a reel assembly, a repositionable level wind may be selectively coupled to a drum to enable powered rotation of the level wind from a first position to a second position. In some embodiments, the assembly may include two arced guide rails, a rotating adjustment arm, a roller bracket, a winding assembly and two fork plates, which may be adjustably mounted on the drum. In operation, the fork plates may be moved to an engaged position that couples the adjustment arm and the roller bracket to the reel flanges so that rotation of the reel causes the winding assembly to be rotated along the guide rails. Once a desired position is reached, the adjustment arm and roller bracket may be bolted to the guide rails and the fork plates may be moved to a disengaged position to allow the reel to rotate independently of the winding assembly.

The present invention discloses a cable reel, comprising an outer frame and a reel assembly. The reel assembly is installed on a lower part of the excavator. The structural point is that: the reel assembly comprises a left reel and a right reel; an inner bracket is arranged in the outer frame; the inner bracket comprises a left bracket and a right bracket which are respectively connected with the left reel and the right reel; and a telescopic cylinder for controlling the swing is arranged between the left bracket and the right bracket. The present invention has the beneficial effects that: the present invention is reasonable in design, increases working efficiency and can roll multiple cables.
