A multiaxial arm joint is provided between an end part of the elastic band and the headphone unit, and includes a first arm, one end of which is connected turnably to the end part of the elastic band, and a second arm, one end of which is connected turnably to the other end of the first arm and the other end of which is connected turnably to the headphone unit. By turning the connecting portions of the multiaxial arm joint, the headphone units are housed within an internal space encircled by the elastic band.

A foldable implement frame is foldable about multiple axes to provide a compactly folded implement. The implement is foldable from a wide, field working position to a relatively narrow position for transport between fields, along roadways, and through field gates or storage doors. The frame is generally comprised of a center frame section that may be hitched to a prime mover, a pair of inner frame sections, and a pair of outer frame sections. The outer frame sections may be folded about their connections to the inner frame sections, and the inner frame sections are foldable about their connections to the central frame section. The central frame section may be rotated to rotate the inner and outer frame sections forward to an upright position, and the inner and outer frame sections may then be folded forward to fold the frame into a narrow position for transport and / or storage.

A balance bike includes a frame, front and rear wheels, a seat, a joining structure, a front fork, and a steering handle. The joining structure is pivotally joined to the frame and pivotal between first and second positions. The joining structure includes a joining end and a receiving end. The front and rear wheels are disposed apart from each other, and the balance bike defines a first longitudinal dimension when the joining structure is in the first position. The front and rear wheels are disposed adjacent to each other, and the balance bike defines a second longitudinal dimension when the joining structure is in the second position. The first longitudinal dimension is larger than the second longitudinal dimension.

There is provided a folding structure of disposable pants which includes an outer wear sheet of pants shape and an absorbent main body adhered to a skin-contacting surface side in the outer wear sheet, wherein elastic members are added at least to circumferences of a waist opening and a leg opening. The structure is formed by folding back a crotch part 5 of the disposable pants over a center pants part 7 on the upside of the crotch part, folding back a left lateral part 8 and a right lateral part 6 of the pants over the center pants part 7, respectively, and then folding back an upper pants part 9 in which the left and the right lateral parts of the pants are overlapped with each other, over a downside part 10 thereof.

A folding chair may include an upper frame, two armrests, two side frames, a front linking unit and a rear linking unit. When the user moves the armrests down to start chair folding process, the front linking unit and rear linking unit start to shrink and bring the side frames closer to each other. In the mean time, two side connecting rods are driven to bring the upper frame to moves down and further squeeze a seat fabric into a space between two side frames to form a compact structure of the folding chair. The size of the folding chair can be determined by extended length of the front linking unit and a rear linking unit. The folding chair proposed in the present invention is comfortable and stable for the user to sit, and all elements of the folding chair can be easily and closely folded into a compact size.

Disclosed is a folding sheet music stand that is capable of being folded into a very compact package. In the folded position, the folding sheet music stand is easily transportable and less susceptible to damage. A carrying bag can be used to transport the folded sheet music stand. The folding sheet music stand can be easily assembled and provides a sturdy platform for displaying folded sheet music to musicians. The folding sheet music stand is fully adjustable so that the folding sheet music stand can be used by musicians using various different types of instruments.

According to various illustrative embodiments of the present invention, a device for a light projection system includes a single light emitting diode array comprising at least one green die, at least one blue die, and at least one red die, a single light collection, integration, and etendue-matching optic element comprising a tapered light pipe capable of collecting substantially all light emitted by the single light emitting diode array and spatially integrating the substantially all the light emitted by the single light emitting diode array, and a telecentric relay using at least one of spherical and aspherical refractive and reflective components. The device also includes an illumination wedge prism, a digital micromirror device capable of modulating the substantially all the light emitted by the single light emitting diode array, and a projection total internal reflection prism, the projection total internal reflection prism disposed between the illumination wedge prism and the digital micromirror device. The device also includes a projection lens, wherein the telecentric relay provides the substantially all the light emitted by the single light emitting diode array through the illumination wedge prism and through the projection total internal reflection prism to the digital micromirror device that reflects the substantially all the light emitted by the single light emitting diode array back through the projection total internal reflection prism that totally internally reflects the substantially all the light emitted by the single light emitting diode array through the projection lens.

A combinative pet cage comprises a front meshed board, a rear meshed board, a left meshed board, a right meshed board, a top meshed board, a bottom meshed board, a plurality of screw parts, and a plurality of connecting parts. The frame of each of the meshed boards is provided with screw holes for the insertion of the screw parts, whereby the meshed boards will be assembles to form a cage body. The top and bottom faces of the frames of the front meshed board and the rear meshed board are further provided with a plurality of insertion holes, whereby two such combinative pet cages can be connected vertically by the connecting parts. A plurality of pet cages can be connected in the same way, and the combined structure thereby formed will be stable.

A multipurpose tool is provided that includes a carabiner and that is designed to fold into a closed position that is relatively compact. As such, the carabiner of the multipurpose tool can be utilized to secure the multipurpose tool to a user, such as to a belt loop or the like, while permitting the multipurpose tool to be folded into a compact form. A handle that includes a carabiner and that can be utilized by such a multipurpose tool as well as a method of forming the handle are also provided. Still further, a multipurpose tool is provided that includes a handle defining a pocket for storing at least one bit in instances in which the bit is not engaged by the bit driver, thereby reducing the likelihood that the bit will be lost or otherwise separated from the multipurpose tool.

A balance bike balance bike includes a frame, front and rear wheels, a seat, a joining structure, a front fork, and a steering handle. The joining structure is pivotally joined to the frame and pivotal between first and second positions. The joining structure includes a joining end and a receiving end. The front and rear wheels are disposed apart from each other and the balance bike defines a first longitudinal dimension when the joining structure is in the first position. The front and rear wheels are disposed adjacent to each other and the balance bike defines a second longitudinal dimension when the joining structure is in the second position. The first longitudinal dimension is larger than the second longitudinal dimension.
