  • Patent number: 9758110
    Abstract: A coupling system comprises a receiving component, an opening in the receiving component defined by a receiving wall and a mating component, configured to be placed into the opening in the receiving component and comprising a mating wall. A plurality of spaced receiving protrusions extends radially from one of the receiving wall or the mating wall, and are located serially to define a retaining groove. A locating rib is formed on, and extends about, the other of the receiving wall or the mating wall such that the mating component is pressed into the receiving component until the locating rib contacts the receiving protrusions. As additional insertion force is exerted upon the mating component the receiving protrusions yield in a radial direction, allowing the locating rib to enter the retaining groove for retention of the mating component relative to the receiving component.

  • Patent number: 7246563
    Abstract: A pivot assembly is provided for attaching a closing wheel frame to a planter. The closing wheel frame has a pair of closing wheels attached at a rear end and a pair of mounting openings formed at a front end. The pivot assembly includes ball bearings having outer races fit loosely within each of the mounting openings of the closing wheel frame. The inner races of the ball bearings are secured to the planter frame using threaded nut and bolt assemblies. The closing wheel frame is pivotal relative to the planter frame during normal operation by relative movement between the inner and outer races of the bearing. Variations of the mounting openings in the closing wheel frame are disclosed, including a tubular part, heavy washer or other annular structure welded to an outside surface of the closing wheel frame, or a bearing housing formed integral with the closing wheel frame.

  • Patent number: 7222862
    Abstract: A tool holder for a power tool, in particular a drilling and/or hammering tool comprising a manually actuable sleeve (40) wherein components of the tool holder are held within the sleeve by a snap ring (100) which snap ring is fitted within the sleeve. The snap ring has at least one resilient arm (102) and the sleeve has a corresponding number of through holes (105) which extend to a radially outwardly facing surface of the sleeve, arranged such that the or each arm is engageable with a corresponding through hole in a snap fit. Each arm and through hole cooperate so that the portion (104) of the or each arm which can be viewed from the radially outwardly facing surface of the sleeve appears in the shape of a symbol. Thus, the snap ring (100) has the dual function of maintaining components, such as a locking ring (42) within the sleeve (40) and of providing an external indication to a user of how to actuate the sleeve.

  • Patent number: 7156575
    Abstract: The present invention relates to a shaft-hub connection having an attachment flange and a clamping element, particularly a clamping ring, attachable thereto, by means of which the shaft end assigned to the attachment flange may be friction-locked to the attachment flange, with an interposed bushing which receives a slip torque. The present invention is based on the object of refining a device of the type initially cited in such a way that the lifetime of the attached components in the drivetrain is increased. This object is achieved according to the present invention in that the bushing is designed in multiple parts in the axial direction.

  • Patent number: 7055655
    Abstract: A bicycle assembly includes a frame portion, a component and a shim. The frame portion has a component mounting section. The component has a frame mounting section. The frame mounting section is removably coupled to the component mounting section by a fastener. The shim is mounted between the component mounting section and the frame mounting section on the fastener to space the component a predetermined distance from the frame portion. The shim includes a shim portion and a handle portion. The shim portion includes two shim sections connected together. The shim sections have free ends spaced from each other to form an open ended fastener opening with the fastener selectively received therein. The shim portion has a predetermined thickness in an axial direction of the fastener opening to space the component a predetermined distance from the frame section. The handle portion extends outwardly from the shim portion.

  • Patent number: 6865791
    Abstract: A method of generating force between a structure and an additional member, particularly for reinforcing an existing structure so that an additional member can share existing load. Pre-cooled or pre-heated shims of shape memory alloy (SMA) are inserted between the additional member and the existing structure, or between different sub-units of the additional member, or between the additional member and shoes fixed for this purpose to the existing structure. On subsequent warming or cooling the SMA shims expand to apply compressive forces to the portions of the structure, additional member or shoe(s) with which they are in contact on their opposite sides. Further compressive, tensile, flexural or torsional forces will be developed within other parts of the structure and additional member as a result of the shim expansion depending on the particular arrangement.
