[Technical field to which the invention belongs]

 The present invention relates to a combination lock, and more particularly to a combination lock having a cord protection device which is preferable for locking a tab of a double zip fastener used in a suitcase or baggage. Or it has rotatable switches and detents to protect the combination lock code from unintentional harm and to help the user change the current code to the desired code.

[0002]

[Prior art]

 A typical example of a lock that locks the movement of a zipper by connecting a hole formed in the tab of a double zip fastener used for a suitcase or baggage to lock the movement of the zipper. It has two dials. Each dial is specified by the manufacturer as a special combination code for each lock.

[0003] If this combination code is invariable, the user may have forgotten the combination code of his suitcase, or if one of the dials was unintentionally harmed even if unintentional. You will not be able to open your suitcase other than destroying your suitcase.

In order to solve such a problem, a recent type of combination lock is used when a user forgets the old code of his / her own combination lock or changes the old code to prevent theft. It makes it easy to change old code to new code that users prefer when they want to.

[0005]

[Problems to be solved by the invention]

 However, when changing codes with this type of combination lock, the user must hold the button with one hand and rotate multiple dials with the other hand. Since the dials are relatively small and the spacing is relatively limited, it is difficult to assign a predetermined number to multiple dials without harming other parts. When a new code is assumed and specified correctly, the user may inadvertently disturb other dials previously specified by the number and make a mistake.

[0006] The present invention has been made to eliminate the above-mentioned disadvantages, and in particular, a new combination having a code protection device that allows a user to specify a new code with one hand and centrally. Provide tablets.

[0007]

[Outline of the invention]

 The main purpose of the present invention is to provide a convenient slide system for the user to change the old cord to the new cord with one hand and concentrate, and to prevent the slide itself from moving. To provide a new combination lock having a cord protection device provided with a lock.

[0008] Another object of the present invention is to provide a combination lock having a cord protection device with a rotatable switch that prevents visual inspection of the state of the tab from outside the lock.

[0009] Still another object of the present invention is to provide a combination lock having a cord protection device capable of preventing the dial from being viewed from the outside of the lock, thereby protecting the dial from unintentional harm. That is.

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1, 2 and 3, the combination lock having the cord protection device according to the present invention includes a generally rectangular case 10, a latch member 20, a dial assembly 30, a rotatable switch 40, and And a rotatable detent means 50.

The case 10 is used to lock the movement of the zipper by connecting a hole formed in a tab of a single or double double zip fastener of a suitcase or baggage to the lock.

The case 10 has a hollow rectangular main body, a concave portion 101 provided at the top of one end portion of the case 10, an annular concave portion 102 formed at one end of the concave portion 101, A hollow cylindrical pivot 103 protruding upward from the bottom of the recess 102 so that a bearing area 104 is formed between the recess 102 and the inside of the case 10 through the annular wall of the recess 102. A rectangular hole 105 provided, a plurality of small holes 106 arranged in an annular shape around the concave portion 102, and symmetrical with each other on each side of the concave portion 101, and a bow shape outward. A post 108 (a portion to which the hole of the tab is connected) is internally threaded at the center of the bottom surface extending upward, and projects upward and forms a hemispherical concave portion 107 inward; Of the recess 101 A circular hole 109 which is provided so as to be slightly laterally shifted at the end opposite to the concave portion 102 and has a sleeve 110, a positioning slot 112 formed so as to face the outer peripheral edge of the circular hole 109, A notch 111 wider than the positioning slot 112, a longitudinal guide 113 (see FIG. 6) formed in the case 10 below the concave portion 101 and communicated with the hole 105, A plurality of viewing windows 114 provided at a predetermined distance apart from each other in a longitudinal projection at the top of the slid position, and a plurality of poles 115 (projected downward from the inner surface of the case 10 near the viewing window 114). FIG. 2), a plurality of first dot-shaped protrusions 116 formed separately around each of the poles 115, and a long extension extending to the other side of the case 10 adjacent to the viewing window 114. A plurality of passages 117 formed apart from the vertical wall of the pit portion and a rectangular lid 119 formed at the center of one end of the case 10 for connecting the rectangular lid 119 having the same shape as the case 10 to the case 10. One screw hole 118, a plurality of recesses 119a formed to be spaced apart so that the ends of the poles 115 are attached, and a plurality of second screws for attaching the lid 119 to the post 108 of the case 10 by screws. And a hole 119b.

Further, a second longitudinal extension 120 and a lateral extension 121 (see FIGS. 2 and 3) are provided in the case 10.

The latch member 20 is slidably provided in the longitudinal guide 113, but is not longer than the longitudinal guide 113, and has a flat rectangular main body 21 and a first main body 21 of the main body 21. It has a vertical slot 22 provided at the end and catch means 23 provided at the second end.

The dial assembly 30 is a known one, and a plurality of dial members are rotatably provided on the pole 115. Each dial member has a numeral dial 31, a sleeve 32, and a first tension spring 33.

The numeral dial 31 has a plurality of first spaced dot-shaped recesses 311 provided in an annular shape on the upper surface, the first dot-shaped protrusion 116 of the case 10, the first center hole 312, and the chamber 313. And a plurality of second spaced dot-shaped projections 314 provided around the center hole 312 and on the opposite side.

The sleeves 32 can be respectively engaged with the chambers 313 of the numeral dial 31, and each has a notch 321 diverging on the peripheral surface and a second central hole 322 for displaying a numeral on both central holes 312. And a plurality of second spaced-apart recesses 323 on the upper surface. When the dial member is provided on the pole 115, the plurality of first tension springs 33 repel the dial member before the pole 115 enters the hole 119 a of the lid 119, and the second spaced dot of the numeral dial 31. Numerical display is performed together with the projection 314.

Since the user can see the numeral dial 31 individually from the viewing window 114, the numeral dial 31 is located further inside as compared with a normal combination lock, and has a small size. The hanging is only exposed outside the case 10.

The generally flat rectangular main body slide 34 has a plurality of sleeve holes 341 that are engageable with the sleeve 32 and each have a connection protrusion 342 that can engage with the notch 321 that is divergent. A second tension spring 343 repelling between an extension at the right end of the slide 34 and a lateral extension 121 of the case 10, a vertical projection 344 and an elastic plate 345 at the left end of the slide 34, The elastic plate 345 is inserted into the vertical slot 22 of the latch member 20.

A rotatable switch 40 having a substantially beveled body 41 has an annular protrusion 42 and a hollow cylindrical shaft 44. An annular projection 42 extends downwardly from the lower surface near the end toward the center, rotatably engages the bearing area 104, and has a first vertical slot 43 and a second vertical slot 421 in the opposite wall. This first vertical slot 43 is engaged with the rectangular hole 105 and the catch means 23. The hollow cylindrical shaft 44 protrudes downward from the center of the annular projection 42, has an internal screw 46 therein, and rotatably engages with the hollow cylindrical pivot 103.

When the switch 40 is placed on the case 10, the switch 40 is fixed from the inside of the case 10 by bolts 47, and attached by a third tension spring 45 and a washer 48 so that the switch 40 can slide vertically. Be inspired.

Further, the switch 40 has four small positioning projections 49 to be engaged with the dot-shaped small holes 106 of the case 10, and these projections 49 are adjacent to the four side portions of the projection 42. ing.

The rotatable detent means 50 of the main body having a hollow cylindrical interior is rotatably and slidably provided in the circular hole 109 of the case 10. Is secured by a large diameter sleeve 110 and is biased by a fourth tension spring 54 and has a radial slot 51 at the top and an outwardly extending periphery of the body. It has a large block 53 and a stop member 52 integrated with the block 53.

The block 53 is engageable with a vertical protrusion 344 of the slide 34, and the stop member 52 is engageable with the positioning slot 112.

The detent means 50 is hidden in the circular hole 109 by the switch 40 which can be slid vertically and is usually rotatable.

FIG. 2 shows the assembled combination lock of the present invention. When the rotatable switch 40 is in the closed position with respect to the case 10, the positioning projections 49 are engaged in two pairs of symmetrical small holes 106 among the small holes 106 around the recess 102 (FIG. 7). See).

Such a configuration establishes that the switch 40 is mounted so as to fit into the recess 101 of the case 10.

In operation, the slide 34 moves rightward due to the elastic force of the spring 343 when the combination lock, in which all the connection protrusions 342 of the slide 34 are engaged with the notch 321 of the sleeve 32 diverging, is in the on-combination state. Therefore, the latch member 20 is also moved to the right position by the elastic plate 345.

Since the catching means 23 is disengaged from the vertical slot 43, the switch 40 is rotated to release a plurality of posts for engaging or disengaging the tabs of the double zip fastener. This allows baggage to be opened (see Figures 2 and 3).

Conversely, when the connecting projection 342 is disengaged from the flared notch 321 (see FIGS. 4 and 5), the slide 34 moves to the left, and the latch member 20 also moves to the left. Engages with the vertical slot 43 so as to prevent the switch 40 from rotating. Thus, the lock is in the closed position (locked).

FIG. 6 shows that the switch 40 is rotating to the left, and the vertical slot 43 and the slot 105 are misaligned so as to prevent the catching means 23 from entering through the slot 105. It has become.

At this time, if a person rotates the dial assembly 30 to make the combination code disorder, the slide 34 is also moved to the left. This is because the connecting protrusion 342 is stopped by the peripheral wall of the sleeve 32, and the elasticity of the elastic plate 345 allows the slide 34 to move to the left.

The engagement of the protrusion 314 and the second spaced recess 323 provides a significant friction between them, at which time the sleeve 32 is rotated with its numeric dial 31. Therefore, the combination code does not change. This configuration protects the combination code of the combination lock from unintentional harm.

9-13 and FIGS. 2 and 3, if the user wishes to change from the old code to the new favorite code, the detent means 50 will appear outside the case 10 so that The rotatable switch 40 is rotated clockwise or counterclockwise. The detent means 50 is actuated by a suitable tool such as a screwdriver or the like which enters the slot 51 in the radial direction, and the detent means 50 is engaged so that the stop member 52 engages the positioning slot 112 of the circular hole 109. Rotate clockwise. As a result, the detent means 50 jumps upward by the elastic force of the spring 54. At this time, the block 53 is stopped on the inner surface of the case 10. Then, the tip of the block 53 is stopped by the vertical projection 344 of the slide 34 so that the slide 34 stops moving leftward with respect to the case 10.

The dial assembly 30 is in a matched state, and the sleeve 32 is prevented from rotating by the elastic force of the spring 33, so that each of the numeral dials 31 can rotate. When a person turns the number dial 31 slightly stronger to overcome the friction between the second spaced protrusion 314 and the second spaced recess 323, a different value is applied to each of the number dials 31 without damaging the sleeve 32. Numbers can be set. In order to change the position of the association between the number dial 31 and the sleeve 32, a new desired combination code is set. Then, the detent means 50 is pressed downward so that the vertical slot 112 and the stop member 52 are disengaged, and when the detent means 50 is rotated counterclockwise, the stop member 52 hits the inner surface of the case 10 and stops. This allows the vertical projection 344 of the slide 34 to move to the left. Then, the rotatable switch 40 is rotated to return to the closed position. This changes the combination code.

In the rotatable switch 40, the configuration of the spring 45 and the positioning projection 49 is such that the switch 40 cooperates with a small hole 106 around the recess 102 at any angle with respect to the longitudinal axis of the case 10. Means you can.

The detent means 50 is normally covered by a rotatable switch 40. A person cannot open the switch 40 without knowledge of the combination code, and changing the combination code does not give a thief a chance.

When the detent means 50 jumps upward, the detent means 50 is stopped by the block 53, so that the user can easily change the combination code with one hand. . Further, if the user does not rotate the detent means 50 back to its normal position, the detent means 50 in the upper position will prevent rotation to return the switch 40 to the closed position, thereby locking the lock. Will not work. This eliminates the harm of any old or new combination code because the combination code is not disturbed by unintended rotation of the dial due to the elastic plate 345 of the slide 34. Will be.

It is to be understood that the above description of the embodiments illustrates more limited exemplary embodiments of the present invention, and will be readily apparent to those skilled in the art without departing from the scope of the claims. Can be changed.
