Abstract:
A hybrid structure configured for detachably attaching thereto an add-on element by at least one connector, comprises a core member having an outer surface and at least one connector receiving element positioned within the core member; and a covering layer connected to the core member by a connection arrangement other than the connector. The covering layer has an internal surface configured to face the core member and an opposite external surface. The covering layer comprises at least one hole extending between its internal surface and external surface, and this at least one hole is aligned with the at least one connector receiving element, for providing access thereto for the connector in a first orientation. The connector receiving element is configured to allow displacement of the connector into a second orientation within the connector receiving element, thereby locking the connector therein.
Abstract:
The invention is directed to novel tripod having a fast opening and positioning mechanism configured to allow a user to open said tripod in a photographing location while maintaining eye contact with an object to be photographed, said tripod comprising legs having telescopic segments and a central locking mechanism operated by a handle having a trigger connected to a loaded spring positioned on a central column, wherein upon pressing on said trigger said central locking mechanism is unlocked to allow spacing of said tripod legs and free fall of said telescopic segments of each one of said legs towards the ground according to the height of the ground in the vicinity of each of said legs, and wherein upon sliding of said handle downward along said central column, said legs with said extended segments become locked in an open form.
Abstract:
A hybrid structure comprises a core member, a covering layer connected to the core member and a reduceable-volume layer disposed at least at a number of regions between the covering layer and at least a plurality of areas of the core member. The covering layer is configured so that, upon application of a flexing force at any of a plurality of areas of the covering layer corresponding to the regions, each such area of the covering layer flexes inwardly into the reduceable-volume layer while maintaining the thickness of the covering layer and flexes back when the force is removed, thereby providing the structure with a suspension quality. The structure further comprises an array of lockable portions associated with the covering layer and an array of corresponding locking portions in the core member, configured to lockingly engage, at least indirectly, the corresponding lockable portions. The locking portions are reinforced relative to portions of the core member which at least partially surround the reinforced locking portions.
Abstract:
In one main aspect the present invention is directed to a compact tripod comprising at least: a) A central column having one or more telescopic segments; b) Two or more tripod legs, each leg having one or more telescopic segments, each of the segments maximally overlap in length and connected to the central column trough a side hinge positioned at the upper side of a multi lobes connector; c) A tripod head; d) A hollow multi lobes connector configure to connect the tripod legs to the central column and to allow at least partial insertion of the head into it in a folded compact state; and e) A central locking mechanism configured to allow opening of the telescopic segments of the central column, said central locking mechanism being operated by at least one opening handle said opening handle having at least one release button connected to a central piston positioned on the central column; wherein in a folded state the central column, the tripod legs and the tripod head are all aligned in one upper line to obtain minimal dimensions of the tripod in a compact close state while keeping a maximal length of the tripod in an open state. In some variations, in a folded position the tripod head may be partially protruding above said upper line.
Abstract:
This presently disclosed subject matter is directed to a bi-directional toy configured to be used as a trampoline and further to be used, upon turning said bi- directional toy upside down, in at least one of the following functions: a playpen-like device, a water pool, and a sphere pool. The toy comprises at least a frame with a plurality of legs configured to elevate the trampoline from a base surface; a bounce mat configured to allow usage of the toy as a trampoline; and the encircling member configured to be attached to the legs for creating a delimited area for use in at least one of the functions.
Abstract:
This invention is directed to a foldable bi-directional toy configured to be used as a trampoline and further to be used as at least one of the following usages: a playpen, a water pool, and a sphere pool, upon turning said bi-directional toy upside down. The toy comprises at least a frame having a pentagon shape connected at each vertex to a leg assembly; a leg assembly configured to allow folding of the toy into a compact flat form, to elevate the trampoline from the ground for enabling jumping and also to serve as a basis for dressing onto it an encircling fabric for creating a delimited area when used as at least one of said usages; a bounce mat configured to allow usage of the toy as a trampoline; and an encircling fabric having a pentagon shape configured to be attached to each of said legs for creating said delimited area when used as at least one of said usages.
Abstract:
A swivel wheel device (Fig. 1) is disclosed, designed to be mounted underneath a load bearing surface (21). The swivel wheel device (Fig. 1) comprises a substantially horizontal bar (2) adapted to pivotally turn about a vertical axle (20); at least one of a plurality of main wheels (3), provided at the bottom of the horizontal bar (2), so that the vertical axle (20) lies in the plane of rotation of the main wheel (3); and at least one of a plurality of support wheels (5), provided at the top of the horizontal bar (2), the axis of rotation of the at least one of a plurality of support wheels (5) is aligned radially with respect to the axis of rotation of the bar (2). When the swivel wheel device (Fig. 1) is positioned on a surface and moved in a predetermined direction, the load bearing surface (21) is supported by the at least one support wheel (5), and the bar (2) is caused to swivel about the vertical axle (20) and align the at least one of a plurality of main wheels' plane (see 3) of rotation in the predetermined direction, thus facilitating motion of the device (Fig. 1) in any desired horizontal direction.
Abstract:
A hybrid structure having suspension quality, comprises a core member having an outer surface, a reduceable-volume layer associated with the outer surface of the core member and having a reduceable volume at least at a number of regions thereof, and a covering layer having an exterior and an interior surface and connected to the core member via the reduceable-volume layer by a connection arrangement. The reduceable volume can be constituted by air gaps spaced from each other; or such gaps and an elastic foam layer portions accommodated within said gaps; or an elastic foam layer sandwiched between the outer surface of the core member and the covering layer, the elastic foam layer constituting a plurality of said regions free of any spacing therebetween. The covering layer is made of such material and has such thickness between said interior and exterior surfaces that areas thereof overlying the reduceable volume are capable of flexing into the reduceable volume, when a flexing force is applied to such area, while maintaining the thickness of the covering layer at said area, and flexing back when the flexing force is released, thereby providing the suspension quality to the hybrid structure.
Abstract:
The invention is directed to novel wheels useful for various products including strollers, vehicles for children, carts, luggage trollies and bags, tricycles, bicycles and toys, and methods of production. The novel wheel comprising a flexible annular segment manufactured by a blow molding process, said segment having at least one layer made of a thermoplastic elastomer; and a wheel hub configured to support the flexible annular segment from each of its sides and to create a cylinder for insertion of an axle therethrough so as to allow connection of the wheel to other components of a product. In one alternative implementation of the invention, the flexible annular segment manufactured is manufactured by extrusion molding process. The invention is further directed to methods for manufacturing the novel wheel.
