The invention is an umbrella-like canopy assembly and the container in which it can be stored. The resulting apparatus can be secured to a hand-controlled mobile carrier. The canopy assembly can be moved from a storage position within the container and then opened to cover, in the least, a portion of the container and preferably one or more areas designated by the user of the mobile carrier. With the apparatus secured to the mobile carrier, for instance, the user and also preferably the contents of the carrier can be shield from the sun and other environmental elements (e.g., rain, snow, and wind). The main parts of the apparatus are the canopy assembly, which is attached to the inside of the container, and means for securing the container to the mobile carrier.

A purification device of baby carriage is provided and includes a main body, a purification unit, a gas guider and a gas detection module. The purification unit, the gas guider and the gas detection module are disposed in the main body to guide the gas outside the main body through the purification unit for filtering and purifying the gas, and discharge a purified gas. The gas detection module detects particle concentration of suspended particles contained in the purified gas. The gas guider is controlled to operate and export a gas at an airflow rate within 3 minutes. The particle concentration of the suspended particles contained in the purified gas, which is filtered by the purification unit, is reduced to and less than 0.75 μg/m.sup.3. Consequently, the purified gas is filtered, and the baby inside the baby carriage can breathe with safety.

A multi-function stroller may comprise a lower chassis shell and an upper occupant shell connected by a quick release pivot joint that provides occupant accommodation that is secure and comfortable. In addition, the structural architecture is designed to allow safe adaptations to the axle configuration. Through flexible suspension arm mounting the suspension-hub-wheel/tire assembly can be quickly assembled/disassembled to provide alternative usage axle layouts. An ergonomic handle assembly may be coupled with the structure for pushing, pulling, towing, carrying, etc. When disassembled, the multi-function stroller can be folded into a compact storage mode. Thus, non-compromised performance, versatility, and usage functionality can be readily achieved and accomplished in a safe manner.

An air-supply device (1) for supplying breathing air into a breathing-air region (2) has at least one inflow opening (4, 6) for supplying breathing air, and also has an interior (10) and at least one outflow region (11), via which breathing air flows out into the breathing-air region (2). The inflow opening (4, 6) is connected to the outflow region (11) via the interior (10). The outflow region (11) is connected to the outflow region (11) via the interior (10). The outflow region (11) is formed on a flexible, air-permeable material (12). In order to provide for flexible use of the air-supply device (1) and to avoid any significant adverse effect to a user, provision is made for the air-supply device (1) to have a sheet-like, flexible portion (16), which has a first flat side (7) and a second flat side (8), located opposite the first. The outflow region (11) is arranged on the first flat side (7). The interior (10) is formed between the first flat side (7) and the second flat side (8). In the interior (10), at least the outflow region (11) has arranged on it at least one spacer, which prevents the outflow region (11) from butting against the second flat side (8).

A seat baffle and a baby stroller are introduced. The baby baffle is disposed in a baby carrier. The baby carrier includes a seat and a support rod erected relatively to the seat and straddling a front end of the seat, the seat baffle includes a baffle cloth, one end of the baffle cloth is fixed to the front end of the seat, the other end of the baffle cloth is detachably fixed to the support rod for shielding the front end of the main body. When the baffle cloth is fixed on the support rod, the front end of the main body is shielded, which is suitable for small babies; after the baffle cloth is detached from the support rod, the front end of the main body becomes open, which is suitable for large babies. The seat baffle can switch between two usage statuses in the baby carrier.

A multi child stroller includes a stroller frame, a first seat and a second seat. The stroller frame includes a front section member, a rear section member, a driving member and a handle member. The driving member is movably connected to the rear section member. An end of the handle member is rotatably connected to the front section member, and a segment of the handle member adjacent to the foresaid end is rotatably connected to the rear section member. When the front section member and the handle member are rotated relative to each other, the driving member is rotated relative to the rear section member, the first link is utilized to rotate the first seat back relative to the first seat body, and the second seat body is utilized to rotate the second seat back relative to the second link.

A protective cover for use in connection with seated persons or pets in a moving conveyance protects the seated person from the effects of environmental elements, such as sun, rain and wind, motion effects, noise, interaction with other people and airborne contaminants, while providing a calming and restful environment for rest or sleep. The protective cover may incorporate antimicrobial treatments or materials to reduce organic load on the exposed side of the cover and the number of washings.

Various embodiments of collapsible canopies for chairs and other objects are described, which have a sheet of material coupled to a frame that when expanded creates the canopy. The frame preferably comprises first and second support pieces that can be coupled together at opposite ends. Each of the support pieces can comprises two or more struts that are hingedly coupled in series, such that the at least two struts can pivot or move about a hinge from (i) a collapsed configuration where one of the struts is stacked on top of the other strut to (ii) an expanded configuration where the at least two struts extend in opposite directions from the hinge.

An air filtering cover is configured to engage over an infant carrier to filter air communicated into an interior cavity thereof. A cover body has a top wall having a pocket with two sidewalls and a filter element and form a flowpath for air communicating through the body and filter to remove dirt, dust, and pathogens from air reaching the occupant of the interior cavity. The filter may be replaceable within a pocket formed in the cover body. A gauge strip may be positioned on the filter which changes in appearance when the filter needs replacement.
