A T-shaped fan blade arm attachment is disclosed for securing ceiling fan blades to a rotor of a ceiling fan motor. The fan blade arms have T-shaped ends with an elastomeric ring disposed adjacent the T-shapes ends. A mounting bracket has mounting holes with opposed slots for receiving the T-shaped ends of the fan blade arms. The opposed slots are preferably aligned at an angle to the horizontal when mounted to a ceiling fan motor. The mounting bracket has a flat surface exteriorly disposed on the mounting bracket adjacent to respective ones of the mounting holes. The mounting bracket has two cams with lock grooves disposed on interior surfaces of the mounting bracket, adjacent to respective ones of the mounting holes. The T-shaped ends insert into the mounting holes and are rotated to guide the T-shaped ends of the fan blade arms into the lock grooves.

The invention proposes a device for attaching an actuator (2) to a housing (4), in particular for an automotive vehicle, the actuator being provided for driving a movable equipment (41) disposed within the housing. The device comprises attaching means for attaching the actuator on the housing. The mounting means comprise two conjugated connection flanges (20, 40), respectively mounted on a connexion face (28) of the actuator (28) and on a connection face (48) of the housing. The connexion flanges are adapted to be assembled according to a male/female type connection at the outside of the housing.

A coupling means having a first member provided with a first diaphragm and a second member provided with a second diaphragm. The coupling means include an additional device having a plurality of protrusions circumferentially distributed on a first cylinder of the first member and a plurality of abutments distributed circumferentially on a second cylinder of the second member, each protrusion presenting at least one sliding face facing a first bearing face of an abutment, each protrusion presenting a blocking face facing a face of the second member referred to as a second bearing face.

The invention relates to a device for supporting and centring a fuel injector in a turbine engine combustion chamber, which includes means for centring a fuel injector along an axis, which are movable in a plane that is radial to the centring axis (52) in supporting means intended for being attached to the bottom of an annular chamber (18). According to the invention, the centring means include at least two radially external tabs (54, 56) each inserted respectively in a circumferential recess (60, 64) of the supporting means, the device including circumferential abutment means (78, 80, 74, 76, 82, 86, 84, 88) of the radial tabs (54, 56) of the centring means in the circumferential recesses (60, 64), the circumferential abutment means being configured such as to enable a greater angular displacement of a first (54, 154) one of the radial tabs in a first circumferential recess (60) relative to a second (56, 156) one of the radial tabs in a second circumferential recess (64).

Provided is a latch member. The latch member, in one aspect, includes an upper portion and a lower portion extending from one or more surfaces and defining a central axis, the lower portion including first and second lower portions circumferentially spaced from one another and axially spaced from the upper portion to form first and second channels, the first and second lower portions having respective first and second leading peaks opposite the first and second channels, the first leading peak axially offset from the second leading peak, wherein the first and second channels are configured to each receive one of two pins of a related hook member and cause the latch member to rotate relative to the hook member, wherein the latch and hook member are configured to alternate between latched and unlatched configurations as the latch member reciprocates substantially along the central axis relative to the hook member.

A one-part male bayonet connector, by means of which at least two components are releasably connectable to one another in a non-destructible manner via an opening, which bayonet connector has a double T-like form in a side view, consisting of a head, a central shaft extending therefrom, and two radial webs extending diametrically from the shaft, which each comprise a fastening means of the bayonet connector facing the head so that, in addition to an interlocking bayonet connection, a frictional connection of the at least two components can be produced between the head and the fastening means of the radial webs.

A vertical joint system for substrates is formed with joints which engage by relative motion in a direction perpendicular to major surfaces and of the substrate. The joints are configured to enable relative rotation of up to 3 degrees while maintaining engagement of the joints. The joints are further configured to form two locking planes one on each of the inner and outer most sides of the joint. Engagement about the locking planes is provided by transverse outward extending surfaces. At least one surface in each pair of engaging surfaces is smoothly curved. The joints can be further arranged to provide a third locking plane parallel to and between the locking planes. The joints are disengaged by combination of a downward rotation of one joint relative the other then application of a downward force.

A quick-release fastener structure includes a body portion and an engaging portion. The body portion is fitted to a first object. The engaging portion is movably fitted to the body portion. The engaging portion has a head portion, a bar portion with an end connected to the head portion, and an engaging-connecting portion disposed at another end of the bar portion. The engaging-connecting portion is insertedly engaged with or separated from a second object. Therefore, the quick-release fastener structure operates by fitting the body portion to the first object and allowing the engaging portion to be engagedly connected to the second object or removed from the second object, such that the at least two objects are coupled together and separated repeatedly and quickly.

A fastening device system for connection at least a first and a second overlapping mats placed on the ground wherein the first mat is aligned over at least one connecting hole of the second mat, the fastening device system comprising, a housing having a first half and a second half wherein the first half and second half are attached together forming the housing. A pin having a foot disposed at the lower end thereof and a shaft having a helical shelf that engages the helical channel of the housing. The pin is configured so that when it rotates 90 in one direction to the housing the pin draws the foot closer to bottom of housing and provides at least one locking position of the foot and locking the foot in place.
