Description

The lock for closing of hand luggages Technical Fiebl

The invention relates to the loch for closing of hand luggages as bags, Buit-caseB etc. Background Art

So far known locks for closing of hand luggages one can divide into key mechanical locks and code locks.

Key mechanical locks have a similar construction to door locks however in a emailer version.

A necessarity of keys and a risk of their loss related to it mean a disadvantage of these locks. Except of that the keys are of small dimensions, adjustment at the lock has to be very proper and manipulation of that is very difficult.

The code locks can be divided into numerical ones with optional combination of the opening code and locks with manually adjusted code combination.

The code locks with manually adjusted combination are opened by plastic cards with slots. In fact it means a passage between key and code locks. Their disadvantage is necessarity of use of supplementary part, it means a plastic card, which means a danger of loss again.

The keys with an optional combination of opening code are usually controlled by three or four small wheels and by each of them it is possible to adjust a number from zerro to nine. From the user's point of view the Betting of wheels in a lift to the whole lock is perpendicular or parallel. Adjustment of the code combinantion is possible only in position when the code for opening of lock is adjusted on the lock with a help of a small opening lever or a special lever on inner side of the lock. By a pressure toward the opening lever in the opposite direction then the opening direction is, or by resetting of the inner support lever, one can adjust new numeric combination.

The wheels are usually very small and require great. accuracy when adjusting. Manipulation with them, especially in aggravated atmospheric conditions as in freeze etc., is very diiiicult.

Disclosure of Invention

Higher mentioned disadvantages are removed by a lock for closing of hand luggages consisting of bath and a buckle fitting in with it, the principle of which is based on the iact, that the bath is equipped with a side hole for a buckle latch and socket on the opposite side. The buckle consists of at least three keys equipped with pins on the bottom Bide, movably set in a basic desk while there is a movable code desk situated under them which is equipped with an operating edges on its upper side, finished by a latch. Under this desk there is a bottom desk situated, which is set on the first elastic element, located on the bath bottom and joint with basic desk by a joint part, which is inserted into the bath socket. Ends of pins are bevelled on the reverse side from side hole of the bath, while each operating edge of the code desk is situated against bevelling of one of pins, it means the first one in order, and the rest of operating edges is gradually - according the order N of pins, determined by code - moved towards the corresponding pins to the latch N-1 times of the distance, which is shorter than diameter of the pin, thereiαre the operating edge corresponding to the second pin is in a standstill position of the code desk moved towards bevelling of the pin one times of the distance which the code desk passes when corrective key is pressed. The code desk is on the opposite side to the latch equipped with a second elastic element. Under the key pins the code desk is with an advantage provided with transversal grooves or point holes.

The lock of the above described construction is very simple. Even in a case of small number of keys it creates a sufficient number of combinations. Thanks to the fact, that the keys are not officially numbered or marked somehow else, the test of even smaller number of combinations with using for example iive keys with the aim of overcoming of the lock, is quite complicated task. The lock is easy controllable, so that easy for use, where often opening of luggage is expected.

Description oi preferred Embodiment

The lock according fig.1 and 2 consists of a bath 1 fixed in a body of luggage and buckle 2 joined with its cover. The bath 1 is equipped with a side hole 4. for a latch 5 and with a socket 17 on the opposite side for inserting of joint part 18 of buckle 2. The buckle 2 consists of a basic desk 8, a bottom desk 11 joint with that by joint part 18 and between them movably set code desk 9 - on one side finished by a latch 5 and on the opposite side equipped with second elastic element 13. The basic deβk 8 is covered by five keys 6 with pins 7, which are passage through this basic desk 8, with points in a standstill position and situated above the code desk 9 . Under the bottom desk 11 there is a first elastic element 12 fixed to the bottom of bath 1.

From the fig.1 one of possible iixing of the pin 7 at the key 6 is visible as well. The pin 7 is movably located in a cavity of the key 6 and secured against releasing by a transversal trunnion 3, fixed in the walls of cavity. Between the upper end of pin 7 and a top of cavity there is the third el asti c element 15 inserted. Between a bottom suriace of key 6 and the basic desk 8 there is the fourth element 16 inserted. An option of movement of pin 7 in a cavity of key 6 together with third and fourth elastic element 15, 16 insures, that it is impossible to notice a diiierence between pressing of a correct moving key and the wrong blocking key 6, whether its solidity or its position towards the basic desk 8 is considered. As another of possible versions the key 6 with a pin 7 are created as one part without the third elastic element 15. Against releasing the keys 6 are insured with a transversal trunnion 3 from the bottom side of basic desk 8.

The code desk 9 in one of possible versions is shown on fig.3. In a code desk 9 sockets 10 corresponding with the number of pins are created. On the bottom of desk, in these sockets 10 those are transversal grooves created by its whole length 14 or point sockets, which are according by codes determined position of operating edge created in front of, in front of and behind or only behind operating edge 19. In the same moment. the bottom of socket is lower in front of the edges 19, so as the trunnion of pin 7 , bevelling of which has moved the code desk 9 , would not touch the bottom of socket 10 and would not break or block another movement of the code desk 9 According the lock code set by producent there are operating edges 19 created at sockets 10 in proper distances from corresponding pins 7, on which bevelled edges of pins 7 press and so move the code desk 9 when pressing the keys 6 in a correct order. Operation bevelling of corresponding pin 7 is always situated on the opposite side to the side hole 4 of the bath 1. Traneversal groove 14 serve for blocking of code desk 9 when pressing keys in a wrong order.

Figures 4A to 4E show how the lock operates. Each figure 4 shows real position of individual pins 7 towards corresponding operating edges 19. Distance a represents the movement of the code desk 9 by pressing of one of the key 6. On fig.5 and 6 the code desk is shown in another version. The code desk 9 is located under pins, again in distances set by producent and equipped with operating edges 19, with transversal grooves 14 in their surroundings and with a lowered bottom in front of operating edges 19.

On the fig. 7 and 8 more simple version of the code desk 9 is presented, where pins 7 even when pressing keys in a wrong order do not reach the code desk 9 with its points. When pressing a wrong key 6, blocking of the code desk 9 cannot occur. The code desk is equipped as well as preceding operating versions by necessary operating edges 19. The opposite extreme case of this version seems to be passage holes in a code desk 9 for pins 7 made in front of operating edges 19. Points of the pins can be made in a ehape of cut cylinder, semicone, cone etc.

If the lock is closed, joint part 18 of the buckle 2 is inserted into socket 17 of bath 1 and the lock is insured against opening by a split 5 which is inserted into hole 4 made in the opposite wall of the bath 1. By the code desk 9 resp. by operating edges 19 on its suriace, the stable code is defined determining an order in which the keys 6 have to be pressed. In this position only one of pins 7 is located with its bevelling above one of operating edges 19 of the code desk 9, on which it adhere when being pressed. By pressing of the key 6 the bevelled part of the pin 7 presses on corresponding operating edge 19 of the code desk 9 and so moves the desk at the distance smaller than the pin's 7 diameter and at the distance it draws up buckle 5 from a side hole 4. By this movement of the code desk 9 the second competent operating edge 19 becomes adjusted under bevelled part of the second pin 7. Thanks to the fact, that the code desk 2 is permanently pressed by the second elastic element. 13 against described moving, the first key 6 has to be hold as far as the second key 6 is not pressed. In the opposite case after releasing of the first key 6 through the second elastic element, the code desk 9 would return to the standstill, locked position and the pin 7 in the order of the second key 6 would not find corresponding operating edge 19 and opening of the key would be blocked. By iofl owing of described procedure complete release of latch 5 from the side hole 4 of bath 1 occurs and the lock is open. Tnanks to the first elastic element 12, which removes the body of buckle 2 from the bottom of bath 1, aiter pressing of the last key 6, the buckle 2 is pulled out from the bath 1 .

In a case of incorrect sequence of presses on key 6, point of pin 2 of the first inncorrectly pressed key 6 fits into the transversal groove 14, eventually to one of point sockets created in straight line under individual pins 7 and will not allow a movement of the desk 9 even in a case of following pressing of the correct key 6.

The code desk 9 can be created even for multiple pressing of the same key 6, by which a number of possible combination increases. One key 6 however cannot be pressed twice or more times in a row, but alwyas after pressing of another key 6.

The first up to the the fourth elastic element 12, 13, 15 and 16, can consist of a spring or a rubber layer, or another elastic material. In practice a soft material has proved for the third elastic element and a solid spring for the fourth elastic element Ife. This combination insures, that all keys 6 have the same resistance, no matter whether they are pressed in correct or incorrect order.
