`
`Description
`
`The present invention relates to a bayonet-type quick coupler for connecting two steering
`
`members, especially for a motor vehicle.
`
`In particular, the invention relates to a quick coupler for connecting two members, one of which
`comprises a socket provided with at least one slot for receiving a lateral protruding part of a shank of
`the other member, the coupler comprising means for locking the lateral protruding part of the shank in
`position inside the slot of the socket.
`
`A quick coupler of this type is already known in the prior art, in particular from document FR-A-2
`628 488 of the applicant, in which the socket comprises at least one helical slot and supports a guide
`and locking member that elastically pushes the lateral protruding part of the shank into the bottom of
`the helical slot so as to lock it in this position.
`
`Furthermore, grooves are provided between the socket and the guide and locking member to
`enable axial movement of this member relative to this socket, while at the same time preventing this
`member from moving angularly around the socket, in order to ensure that the shank is correctly locked
`in position inside the socket.
`
`However, it is understood that the structure of such a coupler is relatively complex and costly to
`implement.
`
`The purpose of the invention is therefore to solve these problems.
`
`For this purpose, the invention relates to a bayonet-type quick coupler for connecting two steering
`members, in particular for a motor vehicle, one of which comprises a socket provided with at least one
`slot for receiving a lateral protruding part of a shank of the other member, the coupler comprising
`means for locking the lateral protruding part of the shank in position inside the slot of the socket,
`characterized in that at least one of the sides of the socket delimiting the slot comprises stop means
`that delimit at least one locking position of the lateral protruding part and in that the locking means
`comprise wedge-shaped means movable in the slot between a first locking position, in which these
`wedge-shaped means prevent the lateral protruding part of the shank from disengaging from the stop
`means of the slot of the socket, and a second retracted position.
`
`The invention will be better understood upon reading the following description, given for illustrative
`purposes only, and with reference to the appended drawings in which:
`
` -
`
`Figure 1 shows an exploded perspective view of a quick coupler according to the invention; and
`Figures 2 and 3 illustrate the operation of this quick coupler.
`
`
`-
`
`A bayonet-type quick coupler denoted by the general reference 1 can be seen in these figures.
`
`This quick coupler enables two steering members, in particular for a motor vehicle, one of which
`
`comprises a socket 2 provided with at least one slot for receiving a corresponding lateral protruding
`part of a shank 3 of the other member.
`
`Furthermore, the quick coupler also comprises means 4 for locking the lateral protruding part of
`the shank 3 in position inside the slot of socket 2 for connection of the shank and socket.
`
`In the embodiment shown in these figures, the shank 3 comprises two lateral diametrically
`opposite protruding parts 5 and 6, for example, consisting of the ends of a rod passing through this
`shank.

`EP 0 791 758 A1
`
`These lateral protruding parts are adapted to be inserted into two corresponding slots 7, 8 of the
`
`socket 2.
`
`In the embodiment shown in these figures, these slots of the socket are axial slots and at least
`one of the sides of the socket 2 delimiting each slot comprises stop means that delimit at least one
`position for locking the corresponding lateral protruding part of the shank inside this socket.
`
`In the embodiment shown, the stop means, for example, consist of a lateral recess 9 and 10 of
`each corresponding side of the socket, respectively.
`
`The locking means 4 comprise wedge-shaped means movable in the or each corresponding slot
`of the socket between a first locking position, in which these wedge-shaped means prevent the
`corresponding lateral protruding part of the shank from disengaging from the stop means of the
`corresponding slot of the socket, and a second retracted position, as will be described in greater detail
`below.
`
`In fact, these locking means 4, for example, can comprise a ring arranged, for example, around
`the socket and denoted in the figures by the general reference 11, this ring being combined with
`resilient means, like a coil spring 12, which urges it axially toward its locking position, whereas the
`above-described wedge-shaped means include parts protruding radially toward the inside of this ring,
`as denoted in the figures by references 13 and 14, [and] these parts protruding radially toward the
`inside of the ring extend into the slots of the socket.
`
`Conventional means (not shown) for holding the ring on the socket are also provided to limit its
`axial movement toward the front end thereof, which is adapted to receive the shank.
`
`As can be seen more clearly in Figures 2 and 3, each radial protruding part of the wedge-shaped
`means 14, for example, of this ring 11, comprises, on one side, a first support surface 14a, for example,
`adapted to cooperate with the end of the socket delimiting the slot, opposite the one comprising the
`stop means 9, for example, and, on the other side, i.e., facing the stop means 9, at least one sloped
`surface for guiding and locking the corresponding lateral protruding part of the shank in the socket.
`
`In the embodiment shown, the corresponding side of the wedge-shaped means 14, for example,
`comprises first and second sloped surfaces 14b, 14c one being an extension of the other, which are
`angularly offset relative to each other, the first one [surface] 14b enabling movement of the wedge-
`shaped means 14 toward their second retracted position during insertion of the shank into the socket,
`by the corresponding lateral protruding part thereof coming to bear against this surface, and [thereby]
`guiding this lateral protruding part in the direction of the stop means 9 of the corresponding side of the
`slot, and the second one [surface] 14c enabling this laterally protruding part of the shank to be locked
`in position in these stop means of the socket.
`
`It is understood that, when the shank 3 is inserted into socket 2, each lateral protruding part 6, for
`example, of this shank, comes to bear against the first sloped surface 14b, for example, of the
`corresponding wedge-shaped means 14, for example, which extend into the corresponding slot 7 , for
`example, of the socket.
`
`This insertion of the shank into the socket then causes these wedge-shaped means, and therefore
`the ring 11, to retract against the resilient bias of means 12, in order to clear the way for this shank.
`
`In addition, the or each lateral protruding part 6 of the shank is guided by the first sloped surface
`14b of the corresponding wedge-shaped means, in the direction of the corresponding stop means
`consisting, for example, of recess 9 of the slot of the socket.

`

`

`EP 0 791 758 A1
`
`Once the lateral protruding parts of the shank are in this position, the resilient means 12 push the
`
`ring and the wedge-shaped means so that the second sloped surface 14c of these wedge-shaped
`means comes to bear against the corresponding lateral protruding part 6 of the shank, for example,
`and against the corresponding edge of the socket delimiting the slot, in order to ensure that the shank
`is locked in position inside the socket, while preventing the or each lateral protruding part of the shank
`from disengaging from the stop means of the socket.
`
`If the shank is not sufficiently inserted into the socket, the ring and the wedge-shaped means,
`under the action of the resilient means, cause this shank to be ejected from the socket so as to prevent
`any incorrect locking position thereof inside the socket.
`
`It is understood that various embodiments of this coupler may be considered.
`
`Thus, for example, various embodiments of the locking means, slots and stop means of the socket
`may be considered.
`
`It is therefore understood that the quick coupler according to the invention has a certain number
`of advantages relative to couplers of the prior art, insofar as its structure is extremely simple, reliable
`and easy to manufacture.
`
`It should also be noted that such a coupler may find numerous applications, especially in the
`automotive industry, for connecting two steering members, in particular for a motor vehicle, such as
`[for connecting] a steering wheel to a steering column member thereof, or the like.
