The invention relates to an anchor for arrangement in lightweight building boards, wherein a lightweight building board has a first covering layer and a second covering layer made from compact material that is stiff in compression, and a core layer, which is arranged between the covering layers and is made from material with a low density in comparison with the covering layers, in particular paper honeycomb, foam or solid wood of low density, having a first anchor part and a second anchor part, wherein the first and the second anchor part are designed to be movable relative to one another, in which a travel between a first end position and a second end position is limited, wherein the first end position is defined by means of first stop means on the first and the second anchor part, and the second end position is defined by means of second stop means on the first and the second anchor part.

The invention relates to a method for applying a joint (2, 102) onto a plate (3), in particular a plate having shape defects. An edge of interest is defined on a portion of the plate (3) onto which the joint (2, 102) is intended to be applied. The plate (3) is then placed on a tool (4, 104) comprising a supporting element (5, 105) made of solid material and a supporting element (6, 106) made of flexible material, in such a way that the edge of interest rests on a portion of the supporting element made of flexible material. While the joint is applied onto the edge of interest, the plate is maintained in a predetermined reference position and the element made of flexible material is pushed against the plate, perpendicularly to an outer surface of the element made of flexible material, the outer surface being opposite to the surface on which the edge of interest rests.

A method for joining two objects by anchoring an insert portion provided on one of the objects in an opening provided on the other one of the objects. The anchorage is achieved by liquefaction of a thermoplastic material and interpenetration of the liquefied material and a penetrable material, the two materials being arranged on opposite surfaces of the insert portion and the wall of the opening. Before such liquefaction and interpenetration, an interference fit is established in which such opposite surfaces are pressed against each other, and, for the anchoring, mechanical vibration energy and possibly a shearing force are applied, wherein the shearing force puts a shear stress on the interference fit.

An internal tensioning structure for use in an inflatable product fulfills the basic function of maintaining two adjacent inflatable surfaces in a desired geometric arrangement when the inflatable product is pressurized. The tensioning structure is formed by connecting a pair of plastic strips sheets via spaced-apart strands, such as strings or wires. When pulled taut, the strands provide a high tensile strength between the two opposed plastic strips. At the same time, the plastic strips facilitate a strong, long-lasting weld between the tensioning structure and the inflatable product.

A method of fastening at least one second object to at least one first object, wherein mechanical vibration acts from a sonotrode on the second object to fasten the second object to the first object. Between the sonotrode and the second object, an auxiliary sheet is placed, for example of paper. After the vibration stops, the auxiliary sheet is displaced relative to the sonotrode for a next fastening step.

A method of anchoring a connector element (10) in a receiving object (66) comprises inserting a distal end of the connector element (10) into a mounting hole in an insertion direction along an insertion axis; inserting a sleeve (36) comprising a thermoplastic material into the mounting hole, the sleeve (36) enclosing the connector element (10); and transferring energy to liquefy at least a portion of the thermoplastic material of the sleeve (36). A machine (500) configured for carrying out the method and a connector element anchoring kit comprising a connector element (10) and a sleeve (36) comprising thermoplastic material.

A plastic component having a core that has a thermoset matrix and an add-on part anchored to the core. At least the securing region of the add-on part can be formed from a thermoplastic and is secured by the securing region to the core of the plastic component, the securing region being attached to the core or inserted or pressed into the core, bonding, in a fusible state produced by the application of energy, in particular by ultrasonic vibrations, with the core and being anchored thereto or therein after solidification, in particular, as a connection anchor.

A precision shaving razor with low cost assembly. A bridge is unitarily molded having a leading platform, a handle attachment mechanism and first and a second cross member each molded to extend substantially perpendicularly to the leading platform. A plurality of base members is each unitarily molded to have a first peg and a second peg for attachment to the cross pieces. A plurality of blade covers each unitarily molded. A razor blade is sandwiched between each blade cover-base pair. In some instances, the blade covers are molded to have hard stops to facilitate precise blade position. In some cases, the bases define angular wash through channels and blade guards spaced to facilitate wash through. In some cases, the skin contacting surfaces of the razor are textured during molding to have a glide improving texture.

A method of manufacturing a lightweight building element assembly is disclosed. The assembly firstly comprises a first object (1) being a lightweight building element that has a first outer building layer (11) and an interlining layer (13). The assembly further comprises a second object (2) secured to the first object. The method comprises firstly providing the first object, wherein the first object has an indentation (19) formed by the first outer building layer. The indentation may form a blind opening or a through opening in the first object. The method further comprises providing the second object (2), wherein the second object comprises an outer surface portion of a thermoplastic material, wherein the outer surface portion is a lateral outer surface portion with respect to an axis. The second object is brought in contact with the first object so that the lateral outer surface is in physical contact with the sidewall (14), and mechanical energy is coupled into the second object so as to cause energy absorption due to friction between the lateral outer surface and the lateral wall, until a flow portion of the thermoplastic material becomes liquefiable and flows relative to the lateral wall. After re-solidification of the thermoplastic material, the flow portion secures the second object to the first object.

A method of bonding a first object to a second object includes the steps of: providing the first object including thermoplastic material in a solid state, providing the second object including a proximal surface, applying a mechanical pressing force and a mechanical excitation capable to liquefy the thermoplastic material until a flow portion of the thermoplastic material is flowable and penetrates into structures of the second object, and stopping the mechanical excitation and letting the thermoplastic material resolidify to yield a positive-fit connection between the first and the second object. The second object has a region of low density, wherein the protrusion penetrates the region of low density at least partly before the thermoplastic material is made flowable, and wherein the first object includes a protruding portion after the step of letting the thermoplastic material resolidify, the protruding portion at least partly penetrates the region of low density.
