An adaptor is secured to a first object. The adaptor includes an anchoring part and an adjustment part. The anchoring part includes a distally facing anchoring surface and a proximally facing first control surface. The adjustment part has a distally facing second control surface positioned to abut against the first control surface. The first control surface or the second control surface or both is/are helical. Thereby a relative z position of the adjustment part with respect to the anchoring part is defined by the relative orientation of the adjustment part with respect to the common axis while the second control surface abuts against the first control surface. This is used to adjust the z position of the adjustment part relative to the first object, in connection with the orientation of the adjustment part being defined and possibly fixed by the function of the adaptor/the adjustment part.

A joint structure is provided in which a first panel and a second panel are joined together by mechanical clinching. The joint structure includes a join region that is formed so as to extend in an elongated shape by forming plural clinched portions in a given arrangement by mechanical clinching. At least one clinched portion of the plural clinched portions is clinched from an opposite panel side from other clinched portions of the plurality of clinched portions.

There is provided a joint structure for a vehicle, the joint structure including: a plate-shaped first member; a plate-shaped second member, of which at least a portion is superposed with the first member in a plate thickness direction of the first member; plural crimped portions provided in a region at which the first member and the second member are superposed, the first member and second member being joined at the crimped portions by mechanical clinching from a side at which the first member is disposed; and a reinforcing portion provided at the first member, the reinforcing portion being inflected toward a substantially normal direction in a vicinity of the crimped portions.

An assembly for a braking system for a vehicle, in particular utility vehicle is provided. The assembly is adapted for holding and fixing at least a first component and a second component, and the assembly includes a base element and a first clamping feature, arranged so that at least one edge area of said first component and/or said second component is clamped by said first clamping feature. To improve the fixation and clamping of the internal components, said assembly also includes at least a rivet-shaped second clamping feature. The base element, the first clamping feature, and the rivet-shape second clamping feature may be integrally formed via injection molding around and/or through the first and second component.

A self-piercing rivet for joining workpieces comprises: a head defining a head diameter, and a shank which defining a shank diameter. The shank on a foot end opposite to the head, partially defines an axial recess which has an axial depth. The shank further includes a flat surface portion or a circular cutter on the foot end. And an axial circular recess is partially defined in a transition portion between the head and the shank.

A joining method for joining a first member having a hole that is opened on at least one surface, to a second member including a material of which a melting temperature is lower than that of a constituent material of the first member, includes: laminating the second member on the first member so as to cover an opening of the hole; and introducing that material of the second member which is softened or melted into the hole through the opening and curing the material of the second member.

An upset protrusion joining gun for joining two parts together by forging a protrusion of one part that extends through an opening in the other part to form a boss that extends over a portion of the other part surrounding the opening.

A joining tool unit including a hold-down device, a linearly movable tool, and a tool counter element. The hold-down device and the tool counter element are provided opposite each other, a workpiece lies on the tool counter element when the workpiece is arranged on the joining tool unit, and the hold-down device is arranged to be supported on a surface of the workpiece. The hold-down device has a light-guiding system, and the light-guiding system is designed to guide a light beam of a light in the direction of a joint location of the workpiece when the workpiece is arranged on the joining tool unit. The light-guiding system is provided on the hold-down device such that the light beam is irradiated onto the joint location solely at an angle which is greater than 0? relative to a movement axis of the linearly movable tool.

To improve the visual probability of the quality of a fixed state of a fixing object fixed to a fixation item, the fixing object includes the supporting part having a hole and a groove formed in proximity to the hole. The groove is provided with a one-way open part, opened in a surface of the supporting part in which one exit of the hole is located and not opened in a surface of the supporting part in which the other exit of the hole is located, and the distance from the center of gravity of the hole to the portion of the groove that is farthest from the center of gravity of the hole is greater than the distance from the center of gravity to a side-surface portion in the hole that is closest to the groove without touching the groove.

Method and apparatus for joining superimposed sheet formed material with an intermediate layer of adhesive together by means of gluing in combination with clinching, at which a tool comprising a first and a second co-axial tool parts, co-operate for producing said joint, said first tool part comprising a punch (1) with an impact surface, surrounded by a stripper (2) with an impact surface, said second tool part comprising a die with an impact surface surrounding a die cavity at the bottom of which an anvil with an impact surface is arranged. In a step before making the clinch joint positioning and locking said punch (1) and said stripper (2) of said first tool part relative to each other so that said impact surfaces present a first, common, squeezing surface (6) of the first tool part, having essentially the same size and form as a second, squeezing surface of the second tool part. Then squeezing together the work pieces (9, 10) with the intermediate layer of adhesive over a surface corresponding to said squeezing surfaces in order to laterally displace excessive adhesive out from the corresponding area of the work pieces.
