A collapsible play structure having a collapsed configuration and an opened configuration comprises: a left panel having a back surface, a front surface, a horizontal axis, and a vertical axis; a left fold out structure coupled to the left panel, the left fold out structure comprising one or more members rotatably coupled to the left panel to be rotatable about an axis parallel with the horizontal axis of the left panel; a right panel having a back surface, a front surface, a horizontal axis, and a vertical axis; a right fold out structure coupled to the right panel, the right fold out structure comprising one or more members rotatably coupled to the right panel to be rotatable about an axis parallel with the horizontal axis of the right panel; and a center panel having a back surface and a front surface, the center panel rotatably coupled to the left panel and the right panel in an orientation that aligns the vertical axes of the left panel and the right panel in a parallel alignment, wherein, in the opened configuration, the left fold out structure and right fold out structure are coupled together by at least one releasable joint.

A children's fort unit includes a first panel comprising a front and a first side permanently joined together and moveable relative to one another along a hinging crease and a second panel comprising a back and a second side permanently joined together and moveable relative to one another along a hinging crease. The fort unit also includes a roof section that includes a hinging crease that allows the roof to fold. The first panel is sized and configured to be releasably joined to the second panel and the roof section is sized and configured to be joined to both the first and second panels.

In accordance with the present invention, a stand-alone pop up assembly and method for making the same is provided comprising a roof structure connected with a plurality of wall panels by way of roof interface component for attaching the roof to the structure. The assembly is moveable between a first position being substantially flat into a one dimensional structure and a second position enfolded into a three dimensional structure by manipulating the outer structure and the internal base. The roof interface component may swivel into place during the movement to the three dimensional structure, thereby positioning the roof structure over the upper portions of the first and second panel walls or, alternatively, a sliding feature is provided with a tab from the roof inserted into a slot at the top of one of the panel walls, thereby sliding the roof into position.

A first grounded portion is at least one of portions of an apparatus that are grounded, and vibrates in accordance with a vibration of at least a first vibration unit. A second grounded portion is at least one of the portions of the apparatus that are grounded, and vibrates in accordance with a vibration of at least a second vibration unit. Then, a first control signal for controlling the vibration of the first vibration unit and a second control signal for controlling the vibration of the second vibration unit are generated, whereby, in a state where the apparatus is on a certain surface, the apparatus moves on the certain surface by a vibration of the first grounded portion grounded on the certain surface and/or a vibration of the second grounded portion grounded on the certain surface.

An inkjet recording apparatus includes an image forming device and a controller. The image forming device includes a recording head unit and forms on paper a fold line image representing a fold line. The controller includes a first selection section. The first selection section selects formation of the fold line image in a first manner or a second manner. In the first manner, the fold line image is formed so as to become invisible after a first period elapses from a first time point at which the fold line image is formed on the paper. In the second manner, the fold line image is formed so as not to become invisible even after a second period elapses from the first time point. The second period is longer than the first period.
