An elastic articulation comprising a first sleeve and a second sleeve is provided. The first sleeve and the second sleeve each include a respective outer armature, a respective inner armature, and a respective elastic body between their respective outer and inner armatures. The elastic articulation also comprises a ring longitudinally connecting the first sleeve and the second sleeve. The ring forms a radial stop between the inner armature and the outer armature of the first sleeve, and between the inner armature and the outer armature of the second sleeve. The elastic articulation improves damping control in different directions.

A stand for vertically aligning borehole charges on non-level surfaces. The stand has a support base. A ball and socket assembly includes a socket portion connected to the support base and a ball portion disposed in the socket portion. The socket portion includes a grip interface to press against the ball portion. A body is connected to the ball portion. A clamp is attached to the socket portion at an interface of the ball and socket assembly between the socket portion and the ball portion. The body is configured to contain a shaped explosive charge for making a borehole. The ball and socket assembly is substantially hollow. The clamp adjusts compression of the ball and socket assembly.

The present invention relates to a joining arrangement having a receiver with a receiving opening and having a ball joint which is spread open into the receiver, wherein the ball joint comprises a joint pin with a joint ball and a joint socket for receiving the joint ball, wherein the joint socket has at least two wings with in each case one internally situated joint surface, wherein the joint surfaces are in contact with the joint ball and enclose the joint ball in sections. According to the invention, the wings have in each case one reboundable resilience section by means of which the respective joint surface presses with a defined force onto the joint ball.

An adjustable mounting apparatus for electronic devices is configured to be adaptable to various support structures, and to facilitate a customized mount orientation for the electronic devices through several degrees of pivot freedom. The mounting apparatus is particularly adaptable to outdoor or industrial environments in which standard support structure modalities may not be available.

A spherical joint includes a body portion and a blocking portion. The body portion includes a ball portion and a joint portion. The ball portion and the joint portion have an inner surface that links the two portions together in an axial direction and an outer surface opposite to the inner surface. The outer surface of the ball portion includes a spherical surface. The body portion further includes a first section and a second section. Each of the first section and the second section intersects with the inner surface and the outer surface such that the two sections together define a gap. The blocking portion is detachably connected to the body portion and shaped to match the gap, so that the blocking portion blocks the gap to form a hollow spherical joint structure. Further disclosed in the present application are a spherical joint assembly and an ultrasonic imaging device.

The invention relates to a support of a ball-joint housing for a connecting rod of a windshield wiper actuating linkage system, the support having a ball-joint housing that extends along a longitudinal axis (B) and is configured to be received in a complementary orifice in the connecting rod. According to the invention, the support is configured to be rotationally joined to the connecting rod. The invention also relates to a connecting rod configured to be rotationally joined to such a support, and to the corresponding joining method.

An angle adjustment apparatus is provided, and includes a fastening component and an angle adjustment component rotatably connected to the fastening component. At least a part of the angle adjustment component is located in the fastening component, and the angle adjustment component can rotate in a horizontal direction and a vertical direction relative to the fastening component. In this way, angle adjustment efficiency is improved. In addition, a communication device can be prevented from being oblique after angle adjustment, thereby preventing a signal coverage function of the communication device from being affected.

A wall-mounted holder is used to fix a photographic equipment to a wall. The wall-mounted holder includes a seat, a cover, and a connecting member. The seat is fixed to the wall. The cover is engaged with the seat in a manner that allows the cover to be movable along an axis relative to the seat. The connecting member has a ball joint that is clamped between the cover and the seat. The connecting member has a shaft that is connected to the ball joint. A part of the shaft protrudes out of the cover, so that the photographic equipment could be mounted to the shaft. Thus, by adjusting the swinging position of the shaft, a camera shot angle of the photographic equipment could be changed.

A ball and socket joint (1) having non-smooth interlocking surfaces (15) wherein projections (8) and corresponding voids (7) mate when the socket (9) and ball (2) are clamped together to prevent the ball from slipping out of position while the ball and socket joint is in use and under pressure.

The invention relates to an indirect rear view system for a motor vehicle, having a bearing element for fastening at least one reflection element, wherein the bearing element forms a coupling region for variable-position attachment to a vehicle-attachable adjustment element, wherein the coupling region for contacting a spherical connection region of the adjustment element has a first contact area and a second contact area axially offset with respect thereto wherein an imaginary separation surface extends through the region of transition of a main body of the bearing element into the coupling region of the bearing element, wherein the first contact area is arranged on one side of the imaginary separation surface and the second contact area is arranged on the opposite other side of the imaginary separation surface. The invention also relates to an assembly method for coupling a bearing element of the indirect rear view system according to the invention to the adjustment element, wherein the bearing element is moved from the direction of the reflection element towards the adjustment element.
