A single control input is realized with the use of a combination slat angle adjustment and window covering opening lift set structure which may be operated by a single wand. A three segment relative control logic is realized which includes movement within in the middle segment that controls the angle of the slats, and movement to and beyond the position where the slats are maximally angled in one direction results in at least one of opening (raising) or closing (lowering) of the slat set by “winding up” a lift cord set which may operate on the interior or exterior of the slat set.

A cord-reel assembly comprises a cord-reel body rotatably installed in the electronic device, a brake member capable of selectively contacting with the cord-reel body, so that the brake member selectively restrains the rotation of the cord-reel body, a manipulation lever having a coupling part connected to the brake member, wherein the coupling part is moved between a first position at which the brake member is contacted with the cord-reel body by the manipulation of the manipulation lever by a user and a second position at which the brake member is spaced from the cord-reel body, a elastic member for elastically biasing the manipulation lever so that the coupling part is moved to the first position, and a damper unit for interfering with the movement of the coupling part in such a way that the returning velocity of the coupling part is delayed when the coupling part is returned from the second position to the first position by the elastic member. With this arrangement, a user does not have to continuously actuate the cord reel until the cord is completely wound.

A centrifugal clutch for motorcycles employs a cam-actuating mechanism having multiple rows of centrifugal force-responsive cam members of a selected density and size to force a series of clutch plates into clutching engagement over the shortest possible distance and least possible speed of rotation while assuring ease of positive engagement of the clutch members in response slight increases in speed of rotation. The cam-actuating mechanism can be employed with a manual override mechanism to manually control locking and release of the clutch members as well as utilizing a torque limiter to absorb shock loads without unduly increasing the size of the clutch so that it will readily fit into the space occupied by existing or standard clutch mechanisms.

A guidewire loader apparatus is provided for loading a guidewire into a lumen opening of a guidewire lumen of a medical device. The loader apparatus includes a first member defining a respective medical device receiving portion and a respective guidewire receiving portion in communication therewith via a respective interface portion. The loader apparatus further includes a second member configured for placement in an opposed relationship to the first member. The second member defines a respective medical device receiving portion and a respective guidewire receiving portion in communication therewith at a respective interface portion. The first member and the second member cooperatively associate with one another between a first position and a second position. In the first position, the medical device can be positioned into at least one respective medical device receiving portion. In the second position, the respective device receiving portions cooperate to align and support the medical device in a manner placing the lumen opening of the medical device substantially adjacent to the cooperating, respective interface portions. This permits aligned sliding receipt of an end of the guidewire into the cooperating, respective guidewire receiving portions, through the cooperating respective interface portions and into the lumen opening of the medical device.

An improved open end wrench having wrench heads at both ends of a shank whereon both wrench heads have arcuate surfaces and backup jaws coplanar with a common torqueing jaw whereby the torqueing jaw is a machined surface of the wrench shank that extends into the wrench heads and is terminated at reliefs at a depth less than half the thickness of the shank, at the intersection of the arcuate surfaces and said torqueing jaw, therein, when excessive torque is applied the relief tends to close whereby the backup jaw and torqueing jaw become nonplanar to each other, therefore wedging the polygonal fastener being worked.

A valve stem construction for a manipulable valve member used to control fluid flow through a valve. The valve stem extends externally of the valve housing for engagement by a valve handle used to manipulate the valve member between open and closed positions. The valve is formed with a plurality of circumferentially spaced concave splines extending longitudinally on the outer surface of the valve stem. The splines are spaced so as to maximize transmission of rotational torque while minimizing flexure and twisting of the valve stem. The spacing and configuration of the individual splines also ensure a strong mating fit with the valve handle.

A mounting assembly includes first and second mounts that connect two objects, such as an electronic instrument housing and a surface. The first mount engages the second mount at a receptacle by way of cooperating detent members. One mount includes a resilient member, upon which cooperating detent members are disposed. The resilient member provides a bias to cause secure engagement of the cooperating detent members. Other features of the mounting assembly include rotational engagement between first and second cooperating detent members such that the angle of the first mount may be adjusted with respect to the angle of the second mount. Also, lead-ins may be included on the second mount so that the resilient members on the first mount may be depressed to ensure proper engagement of the cooperating detent members.

A blow dryer attachment for vectoring directional flow of an airstream exiting a barrel of a blow dryer. The attachment features at least two body components in an articulated engagement having a central passage which may be curved by such articulation to reposition and exit aperture in a nozzle end opposite a connection to a blow dryer. A flexible coupling may be provided as an interface to connect the device to a broader range of blow dryers. A rotational engagement of the first component to the blow dryer allows for rotation of the exit aperture around the axis of the blow dryer barrel for additional adjustment of the angle and direction or vector angle of the exiting airstream from the attachment.

An improved multi-point locking mechanism in combination with a lamp assembly and a support assembly with mating, cooperating plug connectors providing a detachable lamp assembly for use on vehicles, such as boat trailers, for quick removal before exposure to corrosive water. The improved locking mechanism, in addition to providing a means for quick detachment and removal of the light assembly, provides a stronger and durable engagement with the support assembly preventing accidental dislodgement while towing vehicles, like boat trailers. The locking mechanism comprising a corrosive resistant L-shaped member having a horizontal extending plate with a hole through the distal end, and a downward depending section retractably positioned within the support assembly. In the engaged position, the L-shaped member being in a downward position, a receiving pin on the lamp assembly is mated with the support assembly by alignment with the hole in the horizontal plate and the depending section being in communication with a cut-out section in the cooperating plug connector providing the multi-point locking mechanism.

A buckle for a child safety seat comprising a body having an opening for receiving and selectively retaining in position a tang portion of a first belt portion connector, a loop element for connecting a second belt portion, the loop element engaging the tang portion to connect the first and second belt portions, the loop element comprising a base with a pair of legs extending therefrom and abutting at distal ends at a split surface. Each leg includes an anti-spread tab extending generally perpendicularly from the leg configured to engage the opening when the buckle is operably assembled to prevent separation of the split surface and retain the loop element engaged on the tang portion. The anti-separation tabs allow separation of the split surface as the tang is partially withdrawn from the opening so that the lop portion may be disengaged from the tang by movement generally transverse to the tang.

Supply items, such as toner bottles for laser printers, include substantially identical housings amongst the many different colors of toners. To distinguish the items and prevent improper installation, a keying structure attaches per each bottle and is indexed relative to adjacent items. In one aspect, indexing includes rotating a knob of the keying structure about a central axis to provide different keying orientations to an imaging unit in the printer. During installation, users mate the knob with variously arranged channels in a wall defining a slot for receiving the bottles. A lengthy flange on the bottle mates with a lengthy slit of the wall to provide installation stability. Other embodiments contemplate delaying engagement of a shutter on the bottle that prevents the toner from communicating with the imaging unit until the mating of the keying structure is assuredly made relatively proper. This prevents inadvertent mixing of toner colors
