The present invention is directed to an object construction device configured to enclose a specified assembly area and assemble objects, such as toys, using standardized interlocking assembly units. The construction device includes processor with a memory device configured to access an instruction set encoding the assembly instructions of the object. The processor executes the instruction set in order to control and direct an assembly unit manipulator to additively construct or assemble the object from the interlocking assembly units. The assembly units are configured with surface features that interconnect the assembly units such that once connected they are substantially permanently attached to one another.

An assembling device is disclosed. The assembling device is used to assemble a plastic frame and a back plate together and includes: a pressing mechanism configured to press a region of the plastic frame; and a supporting device. The supporting device includes: a supporting platform configured to support the back plate and the plastic frame; and a supporting frame configured to support the pressing mechanism. The pressing mechanism is configured to contact the plastic frame at least one contact point, and a direction of a resultant force of forces applied at the at least one contact point by the pressing mechanism is at an acute angle with respect to a plane where a top surface of the plastic frame lies.

A golf club head includes a metallic section, a polymeric section, and an adhesive material. The metallic section defines an opening and the polymeric section extends over the opening. The adhesive material is disposed between the metallic section and the polymeric section to form an adhesive joint therebetween. The adhesive joint has an adhesive retaining strength configured to inhibit the polymeric section from being detached from the metallic section when the adhesive material is at least partially cured. The metallic section and the polymeric section are also mechanically engaged with one another to form a mechanical joint therebetween having a mechanical retaining strength configured to inhibit the polymeric section from being detached from the metallic section. The adhesive retaining strength of the adhesive joint, alone, is greater than the mechanical retaining strength of the mechanical joint, alone, only when the adhesive material is at least partially cured.

A method is provided for producing a component connection. The method includes the steps of: providing a first component that is made of a thermoplastic plastic material at least in the region of a portion of the surface thereof; providing a ball that is made of a thermoplastic plastic material in at least one region of the surface thereof; pressing the ball on the first component such that the thermoplastic plastic material of the ball comes into contact with the thermoplastic plastic material of the first component; vibrating the ball using an ultrasonic sonotrode and welding the ball with the first component; providing a second component having a through hole; bringing the second component to the first component in such a way that the ball projects at least into the through hole of the second component or a portion projects to a certain extent through the through hole; clipping a clip element to the ball, wherein the clip element projects beyond the through hole and joins both components to one another in an interlocking and/or force-locked manner.

Assembling blow molded parts to form cantilevered structures incorporating a joint among three blow molded parts. A joint incorporates connector components from each part. One part comprises a cantilever, and has a tab with a through hole disposed substantially at the fixed end. The other two parts are assembled using a barbed post-and-hole joint, such that the post is inserted through the hole in the tab. The tab acts in tension at an angle to oppose the moment and shear generated by the weight of the cantilever. Other aspects of the invention include an additional dovetail joint connecting the cantilever part and the other part or parts, The dovetail joint may be blind, and may contribute to supporting the weight of, as well as opposing the moment and shear.

A blank for a box made from an expandable material which is initially moulded generally flat in which, where folds forming hinges are to be made to enable the formation of the box, the tooling which defines the shape of the blank is such as to provide a thickness of the expanded material less than the thickness of the major part of the blank where the folds are to be made having defined edges generally in the direction of each fold the fold and subsequently applying pressure along the area where folds are to be permitted to reduce the thickness of the this blank without removing material therefrom thereby providing hinges to permit formation of the box. The invention also provides a method of making the blank and a box made from the blank.
摘要:
The present apparatus relates to a standardized assembly unit for building objects by utilizing connection elements that mechanically attach together permanently. By utilizing particular surface features and characteristics, such as compressive tabs and interlocking structures, the interlocking units described herein are able to impart structural stability to various objects without the need to provide overlapping layers of material or fasteners. More specifically, utilizing only mechanical linkages and connectors, a collection of interlocking units are utilized to assemble complex objects having high strength, durability and permanence.
