TECHNICAL FIELD This invention relates to lock spindles which are divided into two parts and which are connected by a connecting pin 5. The invention also relates to locks using a split spindle. In particular, the invention relates to solenoid lock types and corresponding mechanical lock types.

BACKGROUND OF THE INVENTION Figure 1 illustrates a prior art split spindle consisting of two spindle parts 4, 5 and a connecting pin 6 therein. In the embodiment of Figure 1, the connecting pin is a single piece bolt which is screwed into a hole in the second hub portion 4 an extension of the hole through the second channel portion 5. The torque head 15 can be rotated through the hole in the hub portion 5 with, for example, a hex wrench, depending on which tool the torque head is machined. The chicken parts of the split chicken 4,5 rotate independently of one another.

... Each button can be fitted with a button of the desired shape. In the exemplary embodiment of Fig. 1, the handle portions 3, 2 are attached to the channel portions 5, 4. In some embodiments, the buttons are not fastened to the spindle, but to the locking pin of the lock. using, for example, a bearing and a yoke ring.

In the embodiment of Figure 1, a solenoid lock (or equivalent ::: mechanical lock type) is attached to the door 1 into which the split spindle is placed. Only the necessary parts of the lock are shown for this description. The lock body 8 is provided with a locking cam 9. and torsion bars 10.11 for both channel sections 5.4. When the knob 3 is turned to open the door 1 • ·, the carriage part 5 turns, while turning the spindle-specific crank 10.

The torque 10 transmits the torque applied to the spindle to the ram cam 9 communicating with the latch bolt, thereby opening the latch. Correspondingly, when the knob 2 is turned to open the door 1 on the opposite side of the door, the channel portion 4 turns, turning: - 1 racket of spindle-specific torque 11 which transmits the torque to the ram 9.

In addition, there is a separate mite 7 between the spindle parts 5 and 4. In some embodiments, a separate spike is not required since the print head 9 has an outer ring that fits into the gap between the spindle parts.

In Figure 1, the button 3 and the spindle part 5 are on the inside, i.e. the so-called exit side.

5 This means that the door can always be opened by pressing button 3, if necessary. This example ignores possible rear locking. In other words, the spindle part 5 is always connected via the crank 10 to the cam 9.

Button 2 and spindle part 4 are on the outside, so-called control side. This means that the transmission of the torque applied to the button 2 and the spindle part 4 to the lock cam may be prevented. In this case the button 2 turns to the empty position and the door can only be opened by opening the lock, for example with a mechanical key. Shutting off the torque force, i.e. locking the door, on the control side is accomplished by the solenoid.

The problem with the embodiment of Fig. 1 is that the locked door 15 can nevertheless be opened from the outside provided that sufficient pressure is exerted on the spindle 2 and the spindle part 4, in particular the longitudinal force of the spindle, while turning the button. The force 12 may be either thrust, traction, or lateral.

Description of the Invention

Figure 2 illustrates an example of an embodiment of the invention in which a connecting pin 23 is inserted through a hole 210 in a hole 210 in a second spindle portion 22 through a bore 29 of the first spindle portion 21. the resilient member (first resilient member) 25 in the bore of the member remains in the space between the connector pin head 24 and the first spindle member body. A gap 28 between the first spindle part 21 and the second spindle part 22 is provided when the spindle according to Fig. 2 is mounted in the lock, the unwanted effects of the force exerted on the button connected to the second spindle part 22 are prevented. For example, if said button is pressed or pulled transverse to the mandrel, the bore extension portion 27 and the spring member 25 prevent the excessive frictional force generated on the mandrel and / or lock from being exerted by this external force, thereby preventing the lock from being undesirably opened. If, on the other hand, the spindle is subjected to a substantially exterior longitudinal force of the spindle, the spring member 25 resiliently pulls said button to prevent the formation of a harmful frictional force. If, on the other hand, said button is pushed vigorously and the button is slidably engaged with the slider portion 22, the sliding of the button prevents undesired frictional force from being pushed. Thus, the embodiment of Figure 2 is advantageous in embodiments in which the j button is attached to the lock cover plate, whereby the button is able to slide in the longitudinal direction of the spindle part ··· ·.

It is also possible, however, to provide an embodiment of the embodiment of Fig. 2 which does not have a bore extension portion 27 in the second spindle portion. However, the designation of the shaded extension 27: illustrates this possibility in Figure 2. However, in this basic embodiment, it is a condition that the second spindle 22 be connected. The attachment of the button to the cover plate is such as to allow sufficient patching of the button with respect to the second spindle portion, which may be difficult to implement.

Figure 3 illustrates an example of another embodiment of the invention. This embodiment is similar in structure to the embodiment shown in Figure 2, but further comprises a second resilient member 211 disposed in the bore extension portion 27 of the second spindle portion 22. In this embodiment, the buttons 5 can be secured directly to the duct portion such as by screw fastening. The second resilient member 27 prevents the generation of a harmful frictional force, for example, when the second spindle part 22 or a button attached thereto is pushed vigorously towards the first spindle part. Of course, the above-mentioned forces on the spindle from other directions will also be considered in this embodiment. Figure 4 illustrates an example of Figure 3 in sectional view.

In the embodiment of Fig. 3, where two elastic members are used, the first elastic member 25 is preferably less elastic than the corresponding elastic member 25 of the embodiment of Figure 2. Since in practically all embodiments of the invention it is preferable that the spring members 25, 211 are springs, greater flexibility in the embodiment of Figure 2 is achieved by using a longer but otherwise similar spring than in the embodiment of Figure 3.

When installing the split spindle shown in Fig. 3 in the lock, the end of the second spindle member 211 "· *: the end facing the first spindle part 21 abuts against the lock.

Figure 5 illustrates yet another example of an embodiment of the invention.

Figure 6 shows the embodiment of Figure 5 from a different angle in section. Let us assume that the first spindle part 21 is the inside spindle part and the second spindle part 22 is the outside; * stem part. Figure 5 illustrates a spindle in an mounting configuration (as well as the previous Figures 2-4) in which the connecting pin 23 is screwed to the second spindle part 22 by bolt threads 26, more specifically into the second spindle part bore 210. extension. In the hole 29 of the first spindle part * * * *, a first resilient member 25 is disposed which remains at the torsion end of the connecting pin. 24 and the first spindle part 21. The first resilient member 25 provides a spindle spring, particularly in the longitudinal direction, if the second spindle 22 is pulled away from the first spindle 21, i.e. out of the door in practical installation. The spindle parts 21,22 rotate freely independently of each other, as in the previous embodiments.

The second duct section 22 comprises, in addition to the actual duct section, an intermediate spindle 22A. The intermediate spindle and the actual spindle portion have a hole for the connecting pin 23. The hole for the spindle is 5 through the spindle. These holes have extensions 27,212. Thus, the second channel portion 22 forms an assembly 22S with the spindle. The actual hub portion 22 and the intermediate spindle 22A are adjustable against each other at the ends 27,212 of the spindle hole extension portions. A second elastic member 211 is disposed on the actual mandrel and intermediate mandrel extensions 27, 212, leaving a gap 213 between the actual mandrel and the mandrel, and the second spring member 211 provides elongation of the mandrel, particularly longitudinally if the second mandrel 22 is pushed toward the first mandrel 21; that is, in practical installation, towards the door.

Further, in the embodiment of Fig. 5, the gap 213 between the main hub portion 22 and the intermediate mandrel 22A is covered by a separate sleeve 22B that provides support, connects the intermediate mandrel and the actual mandrel through its body and protects the second spring member 211. The sleeve does not have to be a separate part but can also be a fixed part of either the spindle or the actual spindle. Figure 7 illustrates an embodiment of a spacer spindle 22A in which the sleeve 41 is an integral part. In this embodiment, the actual spindle part is movable around a · · ψ: V surrounded by a sleeve extension 41. Figure 8 illustrates an embodiment of the actual spindle 22 in which the bushing 51 is an integral part. In this embodiment, the intermediate spindle is allowed to move around the sleeve extension 51.

If, for example implementations of Figures 3-6 the second spindle part 22 is pulled and turned simultaneously, then the first flexible element 25 is flexible, preventing the transmission of force through the inside of the drive disc 10 of the lock to the follower 9. However, if the second spindle part 22 is pushed and turned simultaneously, then the second resilient five tinelin 211 flexibility in preventing the transmission of force of the lock outer side to the roll 11 and thus the follower.

Thus, the inventive embodiment can be implemented in many different ways. The elastic members 25, 211 may be, for example, springs. It is also advantageous for the spindle operation to have a flexible member 25 (such as a spring) to be inserted into the first channel portion 21 and a flexible member 211 (such as a spring) to be inserted into the second spindle portion 22. Each of the elastic members 25 and 211, for example, provides elasticity of 1 to 4 mm, depending on the needs of the embodiment. In the example of Fig. 5, the width of the gap 213 between the parts of the mandrel at the second elastic member 211 forms a maximum elasticity.

15 Although Figures 2 to 6 in the examples second kanaosa 22 is the outside spindle part, is divided spindle also possible to set the switch so that the second spindle part is the inside spindle part and the first spindle part is the outside spindle part.
