Description

(1) and integral with one of its two vertical profiles (5, 6).

  The present invention relates to a button turn key

  intended to receive and imprison the ring of a flat key.

  Over the past few years, locksmith specialists have been

  realizes [the use of flat keys, tent for the actuation of locks equi s external doors of any buildings or apartments that of locks equipping internal doors or leaves, in particular

  service doors, cupboards or window doors.

  These flat keys generally have a standard length

  dart about 6 cm and wind schematically constituted by a part o of grasp of any shape (square, round, hexagonal, ...) cited <. key ring>, which is extended by a longitudinal part cited. <part

  >> wear cut-outs cut to allow manucu-

  use an associated lock to open or close a door or leaf.

  For this purpose, the lock is equipped at its internal part with a rotating mounted part, the barrel, whose rotation in one was started the displacement of a bolt so that it can engage in a metallic piece forming a case. or "ache fixed to the door frame to allow its closing or to be extracted to allow the opening thereof. o More precisely, the barrel of a lock is equipped on its internal part with a multiplicity of elements mobiles or fittings suitable for

  cooperate with the cutouts of the operative part of the associated key.

  When this key is pressed and correctly positioned in the barrel, the linings are moved to the correct positions

  corresponding to a cited condition of unlocking the lock in the-

  which the barrel can be rotated by the key and therefore the bolt can be moved to allow the opening or closing of the door. Flat keys have the advantage of being robust, sim

  magpies to be cut from universal blanks and also easy to transport

  wear in keychain accessories that can have multiple configurations.

  However, the small size of these keys constitutes an in-

  convenient when these are intended for certain uses (keys

  3s service doors, hotel rooms, ...) because they can be made

  cleverly lost, and furthermore the key ring can be awkward

to seize.

  In addition, the aesthetics of these keys is generally not compatible with the style of decoration of an interior, which is particularly annoying in the case of keys intended to remain permanently on a

door or leaf.

  The object of the present invention is to remedy these in conveniences by proposing a versatile key-turning button capable of receiving and imprisoning the ring of a standard flat key by letting the operative part of this key pass beyond allowing its intro.

  duction in the barrel of the associated lock.

  io According to the invention, this key-turning button is characterized in that it is constituted on the one hand by a gripping body comprising a tap hole in its internal part and of which one extremity or first ex tremite is open while the opposite end or second end is provided with a median orifice dimensioned so as to retain the key ring but to allow the passage of the operative part thereof, and on the other hand a locking screw adapted to tapping of the per Ocage of the gripping body and being able to be moved to the internal part of that c. The tap drilling of the gripping body must of course have a diameter sufficient to allow engagement of the key ring. According to the invention, one of the front faces or first front face of the locking screw is equipped with a groove for receiving the key ring while the opposite front face or second front face thereof carries a notch intended to cooperate with the end of a screwdriver. Given this configuration, any stan flat key

  dart can be equipped with the key turn button according to the invention.

  For this purpose, it suffices for the user to engage the key in the Ocage of the gripping body by its first open end and to introduce the operative part into the median orifice which can without that go outside the framework of [ invention have any suitable geometric (slot, circular section, oval, ...) so that the key ring is blocked

  than at the periphery of this orifice.

  The user must then introduce the locking screw in the drilling of the gripping body so that its first front face equipped with the receiving groove is facing the key ring and then begin the positioning of this screw by slightly rotating in the thread of the gripping body using a screwdriver, by placing the end of the latter in the notch equipping the second

front of the screw.

  The following operation c on s i ste to manipulate the op era part

  s roof so as to penetrate the key ring into the recess groove

tion.

  The user can then continue to move the locking screw

  cage in the Ocage of the gripping body, using the screwdriver, this

  as long as it is blocked against the key ring.

  where it should be noted that this displacement can also be obtained

  naked by rotating the operative part of the key.

  In the final locking position, the key ring is simulated on the internal part of the grip body while the ratchet part protrudes from it, so that the key can be used from

  s normal way to operate the associated lock.

  It goes without saying that it is essential for this purpose that the operating part be blocked in rotation relative to the gripping body, which means that the width of the receiving groove corresponds to

the thickness of the key ring.

  It should be noted that the key-turning button in accordance with the invention is particularly suitable for flat keys, the ring of which is symmetrical with respect to the median longitudinal axis of the operative part: in fact, any insertion << in bias,> of the key ring in the receiving groove and consequently any oblique positioning of the part

  2s operative is then excluded.

  The gripping body which is preferably symmetrical in revolution can of course be made of any material (wood, plastic or metal) and have any aesthetic to match the style of the interior for which it is intended (classic, rustic or contemporary). A cylindrical metallic sleeve carries the internal thread

  may, if necessary, be inserted into the internal part of the gripping body.

  A matching aesthetic closure cap is

  as a rule added to the gripping body.

  s This cap can simply be force-fitted into the gripping body, at the first, open end of it. The characteristics of the key button which makes the object and of the invention will be described in more detail with reference to the appended drawings in which: - Figure 1 is a schematic longitudinal sectional view of the button turns key in position of use, that is to say trapping the ring of a flat key, - Figure 2 is a perspective view of the gripping body,

  - Figure 3 is a perspective view of the locking screw.

  According to the figures, the button turns key consists of trots o elements, namely a gripping body 1 shown in Figure 2, a locking screw 2 shown in Figure 3 and an iron cap

step 3.

  The gripping body 1 is constituted by an element of revolution whose aesthetics is of course not limiting the invention. According to Figures 1 and 2, the gripping body 1 is equipped at its internal part with a tap hole 4 whose first end 5 is open and cooperates with the closure cap 3 which is forced into it and while that the second end 6 is closed by a

  o wall provided with a median orifice 7.

  According to Figure 1, the tap hole 4 of the gripping body 1 has a diameter sufficient to allow engagement of the ring 9

a standard flat key 8.

  The median orifice 7 is in turn dimensioned so as to retain the key ring 9 but to allow the passage of the opera part

roof 10 extending it.

  Thus and as shown in Figure 1, the key ring 9 can be trapped in the internal part of the gripping head 1, this in a way that will be described in more detail later in this presentation, while the operative part protrudes from the outside so as to per

  put to handle the barrel of the associated lock.

  According to Figures 1 and 3, the thread 11 of the locking screw 2 corresponds to the thread of the per Ocage 4 of the gripping body 1 so

  allow it to be enforced by rotation according to arrow A (Figure 1).

  To allow this displacement, one of the front faces 12 of the locking screw 2 is equipped with a notch 13 intended to receive

  the end of a screwdriver not shown in the figures.

  The front face 14 opposite to the front face 13 of the screw

  blocking 2 is equipped with a receiving groove 15.

  The width of this receiving groove 15 corresponds to the thickness of the key ring 9 so as to allow it to be inserted therein and

s block it in rotation.

  Given the above-mentioned configuration, the blocking of a flat key 8 in the button turns the key by setting the following steps: - engagement of the key 8 in the drilling 4 of the gripping body 1 and o introduction of the operating part 10 in the orifice 7 so that the key ring 9 is retained at the level of this orifice in the position represented in FIG. 1, - engagement of the locking screw 2 in the perage 4 of the pre body hension 1 so that its front face 14 fitted with the receiving groove 15 faces the key ring 9 and initiates the movement of the locking screw 2 according to arrow A by means of a screwdriver inserted in the notch 13, rotation of the operating part 10 of the key 8 while maintaining the key ring 9 in contact with the front face 14 of the locking screw 2 until this ring 9 penetrates into the receiving groove 15, - continued movement of the locking screw 2 according to arrow A a ['aid e of the screwdriver while holding the key ring 9 in the receiving groove 15, until locking, - force-fitting of the closing cap 3 into the per, cage 4 of the

2nd gripping body 1.
