An improved ergonomically efficient tool having two adjustable and lockable bends allowing the handle to be bent to selected angles at each bend. An alternate embodiment includes a telescoping feature between the two bends allowing the handle length to be adjusted to the height of a user. The two bends and the telescoping feature cooperate to minimize a user's need to stoop over to use the tool and make it easier and more ergonomically efficient to use. A coupling feature in a further embodiment allows multiple tool heads to be easily attached to the bendable handle.

A sliding-type portable communication apparatus, which has an pop-up type display device, including a first housing; a second housing adapted to slide on the first housing along the longitudinal direction thereof; and a display device having a first region, which is exposed or concealed according to the position of the second housing, and a second region, which is disposed adjacently to the first region and which remains exposed regardless of the position of the second housing, the display device being adapted to advance or retract in a direction perpendicular to the upper surface of the first housing, while remaining in a plane to the upper surface of the first housing.

A manually-operable shovel for efficiently moving material, including a shovel blade, a shovel handle, a joint for attaching the shovel blade to the shovel handle, and an articulation device cooperating with the joint for permitting the operator to position the blade to a predetermined fixed angle in relation to the direction of blade movement for moving the material in a predetermined desired relation to the direction of blade movement. The articulation device is moveable between an unlocked position wherein the angle of the blade in relation to the direction of blade movement is variable and a locked position wherein the angle of the blade is locked into a fixed angle in relation to the direction of blade movement. The articulation device automatically assumes the locked position during a forward, material engaging movement of the shovel and automatically assumes the unlocked position during a rearward material disengaging, movement of the shovel.

In a stereoscopic image conversion panel and a stereoscopic image display apparatus, the stereoscopic display panel includes a first lens substrate, a second lens substrate, a stereoscopic image lens part and a lens liquid crystal layer. The stereoscopic image lens part is disposed between the first and second substrates, and includes a main lens and sub-lenses with a concave shape. At least one sub-lens is disposed at opposite edge portions of the main lens. The lens liquid crystal layer is received by the main lens and the sub-lenses, is disposed between the first and second lens substrates, and includes liquid crystal molecules having an anisotropic refractive index. The lens liquid crystal layer refracts a polarized light at an interface between the lens liquid crystal layer and the stereoscopic lens part, to convert a flat image into a stereoscopic image. Therefore, the thickness of the stereoscopic image panel can be reduced.

A combined shovel and clearing tool with a shovel and a clearing tool member for being coupled to the shovel. The clearing tool member can be selectively retained in a usage disposition, such as relative to a leading edge of a shovel blade, and in a storage disposition, such as relative to a trailing edge of the shovel blade or relative to a handle of the shovel. The clearing tool member can be retained by, for example, a clip arrangement, an elastic tether, or a rigid arm. Bristles can project from an obverse side of the shovel blade. The handle and the blade can be reconfigurable by, for example, a relative pivoting or a selective coupling of the handle with multiple receiving portions on the blade. A universal clearing tool can be coupled to a standard shovel.

A shovel for manual use, comprising a shovel blade having concave and convex faces and defining a longitudinal center-line and having side edges, an upper edge and a forward cutting edge. The shovel blade defines a handle connector receptable having a shovel handle fixed therein. A root cutting blade is fixed to the shovel blade substantially along the longitudinal center-line and projects from the concave face of the shovel blade. A sharpened root cutting edge is defined on the root cutting blade and is oriented toward the forward cutting edge of the shovel blade. The root cutting edge of the central blade preferably defines an intermediate edge recess and forms a slightly inclined sharp edge section for enhancing root cutting action. A pair of side blades are fixed to side edge portions of the shovel blade and are oriented in diverging relation projecting from the convex face of the shovel blade. The side blades also preferably define forwardly inclined sharpened cutting edges and are located for cutting surface roots at respective sides of the shovel blade to facilitate efficient fracturing of the soil when the shovel blade has penetrated into the soil and is pivoted to pry a soil load loose from the surrounding soil.

A device for gathering and lifting leaves that utilizes a specially designed pair of leaf scoops that are pivotally secured to each other in opposing orientation via their handles. Each of the leaf scoops is provided with a separate pivotal axis that extends through the handle of the leaf scoop. The leaf scoops are offset from each other so that the handles can be operated like the handles of a pair of scissors in order to open and close the heads of the leaf scoops relative to each other, thereby capturing leaves between the scoop heads so the leaves can be transported and so the leaves can be released when the leaves have been transported to the desired location. The device is provided with a central handle that attaches midway between the pivotal axes so that the user can grasp the central handle when lifting the device and the leaves.

A manual snow plow with ergonomic features comprises a snow scoop, two (2) articulating struts extending upward from the scoop and two (2) hinged rounded braces placed against a user's shoulders during use. The struts are provided with cross bracing which provide size adjustability and stability to the plow. A set of position adjustable hand grips extend from each strut in a rearward fashion to control the device during use. A pair of casters provided on a rear of the snow scoop allows the device to ride over cracks and other uneven surface variations. The snow plow becomes an extension of the user's body and thus enables the user to use the force of their entire body to move snow.

The invention relates to an exercise device for use by a user on a selected surface material comprising a grasping member having a first end and a second end, a first tool head mounted to the first end of the grasping member and a second tool head mounted to the second end of the grasping member.

The socket has a slot configured to receive a proximal end of a blade at its distal end, the slot. The slot is further configured to receive the blade such that the proximal end of the blade is positioned continuously through the slot without interruption. The shovel further includes a foot step having platform for accommodating a person's foot at the proximal end of the blade. The footstep has a support integral with the platform such that the support contacts the bottom surface of the blade at a location distal from the proximal end to provide support to the blade and the platform.

An ergonomically-configured handle for tools such as cleaning devices and, more particularly, to a handle for a broom or mop (for example) is formed with curved end terminations to reduce back strain and provide ease of use. A first curved end termination is attached to a tool head (such as a brush, rake head or the like) via an elbow joint. A straight section of handle is then attached to the first curved end termination, where a second curved end termination is then attached to the opposite end of the straight section. A handle grip may be disposed over the termination of the second curved end termination.
