Description

The present invention relates to a system for controlling the delivery and

  the return of selected articles, such as

  tools, keys and similar items that do not

  does not require an individual supervisor or guardian and who generally encourages and ensures the correct return

  articles in a station or central station.

  The invention also aims to provide a system of

  security and management for articles, which requires the use

  selected key to remove items from a

  detention station and which requires the correct return of the

  and lock it in a locked mode before the unlock key can be removed from the restraint. Other advantages and characteristics of the invention

  will be highlighted, in the following description,

  given by way of non-limiting example, with reference to

attached drawings in which:

  FIG. 1 is a perspective view of the security system according to the invention, where the article has been represented in the form of a tool; Fig 2 is a fragmentary perspective view of a locking mechanism and unlocking articles of the security system according to the invention; and Fig. 3 shows another electrical arrangement of the

  security system for articles according to the invention.

  In the drawings, and more particularly in FIGS. 1 and 2, the security system for articles according to the invention

  has been designated as a whole by reference numeral 10.

  It should be noted that the system or apparatus according to the invention can be used for different types of articles, such as keys for starting automobiles in a car sales garage, or tools in a workshop, etc. For the sake of convenience and simplification of this

  description, the article that will be the subject of the description

  The following is a tool 12 which, as shown in Fig. 1, is a portable sanding machine. Furthermore, it should be noted that the system or apparatus according to the invention could be used for many similar or corresponding articles and that in it is in this respect that the use of the

present invention is envisaged.

  Considering the system or apparatus 10 according to the present invention, it is seen that it comprises a central retaining station 14 o the corresponding tool or tools 12 are stored or retained in place The retaining station 14 shown in Figs 1 and 2 includes a housing 16 provided with two

  key entries 18, 20, for each article provided.

  The housing 16 has a bottom 22 and a surrounding structure 23 consisting of an upper wall, side walls

and extreme walls.

  There is provided inside the housing 16 a locking mechanism for securing the article or tool 12 in the area around the retaining station 14.

  Fig 1 and 2, we see that this locking mechanism com-

  takes a locking bar 24 of elongate profile which is provided with a series of teeth 26 formed on its lower side Two gears 28 and 30 support the bar of

  lock 24 at its opposite extreme parts, each

  having a central slot 32 for receiving

key.

  In addition, as shown in FIG. 2, the lock bar

  in its opposite extreme parts two

locking sleeves 34, 38.

  In positions adjacent to the lock bar

  24, there are provided two locking lugs 40, 42

  The locking tabs 40 and 42 are arranged to engage with the locking notches 34 and 38 in the locking bar 24 in order to

  immobilize it in a stationary position.

  An article or tool 12 comprises a fastening chain 44 which is itself fixed on a locking key 46 having an opening 48 which is arranged to receive

  a locking pin 50 supported by a support post

52.

  In addition, a master key or release key is provided.

  54, which comprises, like the key 46, an opening 56 for receiving a locking pin 58. In use, the article 12 is in a position of

  locking and retaining which is shown in Fig 2.

  In this locking mode, the pin 50 is engaged in the opening 48 in the article locking key 46 The locking key 46 enters the slot 32 in the gear 30, but this gear 30 can not be turned due to the engagement of the locking latch 40

  in the notch of the locking bar 24.

  To unlock the article 12 with respect to the holding station 14, the unlocking key 54 is inserted in

  the inlet 20 and in the key passage slot 32 of the gear

  The unlocking key 54 is inserted until its inner end 54 comes into contact with the locking tab 40 by pulling it out of the corresponding notch 34. This causes the bar 24 to unlock and the gear 28 can turn clockwise, looking at Fig 2, under the action of the key 54 The movement of the gear 28 in the direction of clockwise makes move the locking bar

  24 to the right, looking at Fig 2 This movement pro-

  is a rotation of the gear 30 in the direction of the

  guilles of a watch, looking at Fig 2, and

  is a rotation of the lock key 46 The spindle

  50 and the opening 48 are arranged

  However, rotation of the locking key 46 in a clockwise direction causes the opening 48 to rotate to disengage it from the locking pin 50.

  Once the locking pin 50 has been completed,

  the unlocking key 46 can be removed and, at this moment, because of the thrust of the spring exerted on the locking tab 42, the latter engages in the notch of locking 38 thus placing the locking bar 24 in the condition

locked.

  When the unlocking key 54 has been turned approximately

  a quarter of a turn to reach the condition of

  locking key lock 46, the opening 56 is

  engaged on the lock pin 58 This results unblock

  unlocking key cage 54 in the restraint station

  14 because the locking bar 24 is blocked by

  locking latch 42 in notch 38.

  To allow removal of the unlocking key 54, the article or tool 12 must be brought back into the holding station and the locking key 46 must be inserted into and locked inside the housing 16.

  removal of the unlocking key 54, the locking key

  rust 46 associated with the article 12 is inserted into the slot 32 of the gear 30, coming into contact with the

  locking latch 46 and pulling it out of the

  checkmark 38 This allows a shift of the

  rusting 24 to the left, looking at Fig 2, by

  rotation of the unlocking key 46 in the direction of

  milking clockwise When the bar of ver-

  ratchet 24 moves to the left, the gear 28 is rotated counterclockwise, so that the opening 56 in the unlocking key 54 rotates disengaging from the locking pin 58 Once this release has been

  realized, the locking tab 40 is aligned with the

  checkmark 34 and, as a result of the thrust exerted

  out on the latch 40, this one comes into

  in this notch 34 and consequently causes locking of the locking bar 24 At this moment, the unlocking key 54 is in the vertical position and it can be freely removed from the casing 16 Meanwhile, the rotation of the locking key counterclockwise locking of the article 46 has caused its rotation so that the pin opening 48 formed in said key comes to receive the locking pin 50,

  thus producing a blocking of the associated article.

  The shape of the inner end 46a of the green key

  rusting 46 is important since its conical profile and the shape of the engagement slot 42 formed in the locking tab 42 allows this latch 42 to engage in the notch 38 when the locking key 46 is in

  the horizontal unlocked position.

  It should be noted that the locking bar 24 and the gears 28 and 30 could be provided with a suitable guiding structure for supporting them inside the casing 16, while nevertheless allowing movement of the respective components. In Fig. 3 there is shown an electrical arrangement of the article security system according to the present invention, which system is generally designated by numeral 60. In this regard, said system comprises an article key 62 which is arranged to be inserted into a dual contactor assembly which includes contactors 64 and 65 There is also provided an unlocking key 68 which is arranged to be inserted into another assembly at

  double contactor, comprising contactors 70 and 71.

  In addition, an electromagnet 66 is provided which, when actuated by a current applied thereto, is arranged

  for locking and holding in position the locking key 62.

  In the same way, a second electromagnet 72 is provided.

  which, when properly excited, is arranged to

  lock and hold in place the release key 68.

  In use, as shown in Fig. 3, an article key 62 is held in the corresponding set of contactors since the electromagnet 66 is actuated by a current applied to it by a battery 74 To unlock the key 62 and removing the associated tool, the unlocking key 68 is inserted into position and turned The rotation of the key 68 causes the actuators 70 and 71 to be actuated so that they move to their other positions

  compared to those of Fig 3 This switching of the con-

  driver 71 causes de-energization of relay 68 and

  allows the removal of the locking key 62 The action-

  The contactor 70 causes the circuit of the electromagnet 72 to be closed in order to actuate it and to block

  and hold in place the unlock key 68 As a result,

  quence, the key 62 can be removed while the key 68 is

  kept in a locked condition.

  To remove the key 68, you must insert the key of ver-

  rusting 62 in the dual contactor assembly comprising

  the contactors 64 and 65 The insertion of the key 62 and the ac-

  Switching the contactors 64 and 65 from the position shown in Fig. 3 causes the electromagnet 66 to be actuated to retain the locking key 62, while the electromagnet 72 is de-energized thereby allowing

  removal of the unlocking key 68.

  Of course, the present invention is in no way

  mitigated to the embodiments described and shown; it is capable of numerous variants accessible to those skilled in the art, depending on the applications envisaged and without

  we do not deviate from the spirit of the invention.
