The vibration reduction connecting component (50) comprises a vibration reduction connecting frame (53) connected to the frame structure (11), and an inverted U-shaped structure (51) positioned in the vibration reduction connecting frame (53), connected to the lower part of the vibration reduction connecting frame (53) through supporting legs and connected with the second fixing component (100). The vibration reduction device of the present disclosure can provide excellent vibration reduction and impact-prevention protection for electronic products and precision electronic equipment. It is especially able to protect electronic products and precision electronic equipment installed on mobile equipment, such as a vehicle, against physical damage while under severe travelling conditions, as well as ensure their normal operation. The vibration reduction device according to the present disclosure not only has a simple structure and occupies little space, but also has simple installation and long service life, and can be suitable for varying load conditions.

A variable stiffness spring is provided that includes a dielectric diaphragm having a biaxially pre-strained film, where the dielectric diaphragm includes an out-of-plane stiffness at zero voltage, a first electrode disposed on a first side of the dielectric diaphragm and a second electrode disposed on a second side of the dielectric diaphragm, where the out-of-plain stiffness is relaxed by an applied voltage between the first electrode and the second electrode.

Improved equipment bases and methods for making and using same are disclosed herein. The equipment base can include a first coated substrate including a first part having a first thickness sized to provide the load-bearing support for the equipment, a first elastomer coating the first part, a second coated substrate positioned adjacent to the first coated substrate, the second coated substrate including a second part having a second thickness sized to provide the load-bearing support for the equipment, and a second elastomer coating the second part. A first seam can be formed between the first and second coated substrates to allow for moisture to pass between the first and second coated substrates so that moisture is allowed to seep away from the bottom of the equipment.

The suspension strap assembly for a punching bag is an apparatus that is configured for use in physical training. The suspension strap assembly for a punching bag suspends a heavy bag in a manner appropriate for use in the physical training for boxing activities. The suspension strap assembly for a punching bag comprises a superior mount, a suspension apparatus, and a heavy bag. The suspension apparatus attaches the heavy bag to the superior mount. The heavy bag provides a target used for physical training. The superior mount suspends the suspension apparatus and the heavy bag from a load bearing structure such that the load of the suspension apparatus and the heavy bag are incorporated into the load path of a building or structure.

In some examples, a shock absorption bracket includes one or more damping pads coupled to a facing surface of an absorption leg. The absorption leg is attached to a support leg and defines an internal corner with the support leg. The support leg is configured to attach to an equipment cabinet. The shock absorption bracket may be configured to define a gap between the damping pads and one or more support surfaces of the equipment cabinet. The shock absorption bracket may be configured to attach to a rear section of an equipment cabinet having an equipment access in a front section of the equipment cabinet.

A vibration and sound deadening treatment applied to the exterior of downspouts or other gutter pieces which quiets any sound generated when water or other weather contacts the downspout. When placed on the exterior of the downspout, especially near turns in the spout, sound generated by rain and water moving through the downspout is dampened by reducing or removing completely the vibrations generated by the rain and water. This prevents the need to place anything inside of the downspout that may wind up clogging the spout and drain.

Elastic joint comprising:—an inner ring (1) provided with an axial opening (11) for being mounted on a shaft “E” and with an outer surface having: two opposite intermediate sections (13) having a decreasing cross-section towards opposite ends of said inner ring (1) and forming supporting zones for the metal wire cushions (3), and two end sections (14) having a smaller cross-section than the central section;—an outer ring (2) provided with an outer cylindrical surface (21) for mounting the ring to on a support (S) and with an inner surface with two intermediate portions (22) having a decreasing cross-section towards opposite ends of the outer ring (2), facing the intermediate sections (13) of the inner ring (2); and—metal wire cushions (3) arranged between the inner ring and the outer ring (2).

A spacer (1) for vibration-damped fastening of a mounting part (2) to a carrier part (3), wherein the spacer has a base body (4) with a first flange region (5) and a second flange region (6) which is opposite viewed in the longitudinal direction (L) of the base body and with a passage (7) in which a fastener (8) which is connected to the carrier part, can be received at least sectionally. The base body has an at least two-part design with a first body part (9) and at least a further, second body part (10), wherein the body parts can be detachable connected to one another to create the base body and wherein, in the connected state, a gap region (11) is provided between the first and second flange region, by which the border of a fastening hole (18) configured in the mounting part can be received.

The invention relates to an impact compactor which includes a first part on which at least one non-round compactor drum is rotatably mounted; and a second part which is connected to, and movable relative to, the first part. The impact compactor also includes a damping arrangement which is connected between the first and second parts and which is configured to provide a damping function for the relative movement between the first and second parts. The damping arrangement includes an outer tubular member which defines a non-circular inner channel/passage; a non-circular inner shaft member which defines a first axis of rotation and which is positioned, at least partially, in the channel/passage defined by the outer tubular member; and at least one wedge formation which is wedged between the shaft member and the tubular member. The wedge formation is at least partially resiliently deformable and is configured to resist/oppose relative rotation between the shaft member and the tubular member about the first axis of rotation. One of the members is connected to the first part, while the other member is connected to the second part.
