Technical Field

The utility model relates to a suitcase field technique especially indicates a be equipped with locking roller's brake component's suitcase.

Background

With the increase in size of luggage, luggage equipped with rollers has been put to practical use. With the help of the wheels, the user can easily move the heavy luggage case sideways.

However, since the luggage case is moved without authorization on a slope or an inclined floor, it is necessary to provide a roller lock mechanism capable of locking the roller as appropriate, and when the operation portion for operating the roller lock mechanism is located near the roller, the user lowers his/her body posture to perform the locking operation and the unlocking operation, which are troublesome. Therefore, various kinds of luggage cases have been proposed in which the locking operation and the unlocking operation are considered (for example, refer to patent document 1).

The technique of patent document 1 is as follows: in a luggage case having a stowable handle (hereinafter referred to as a telescopic handle) and casters, a wheel lock mechanism and the telescopic handle are mechanically connected by a wire, and when the telescopic handle is retracted, the wheels are set to a locked state, and when the telescopic handle is pulled out, the wheels are set to an unlocked state (that is, a free state).

Since the telescopic handle is at a high position, patent document 1 has an advantage that the locking operation and the unlocking operation can be performed in a comfortable posture. However, although the user sometimes wants to temporarily stop the luggage case on a slope or an inclined floor while pulling out the telescopic handle, the user has to retract the telescopic handle to prevent the movement thereof, which is troublesome, since the luggage case moves without authorization when the telescopic handle is pulled out in the technique of patent document 1.

When the usage is diversified, the luggage case that can retract the telescopic handle to lock the roller needs a structure that can arbitrarily lock the roller when the telescopic handle is pulled out, so that the improvement of the current luggage case is needed.

Detailed Description

As shown in fig. 1 (a), the luggage case 10 includes a case body 11, a lid 13 connected to the case body 11 by a hinge 12, rollers 14 provided at the bottom, a retractable handle 15 provided on the case body 11, and a non-retractable handle 16.

The luggage case 10 can be rotated 90 ° from the illustrated state to place the case body 11 downward and the lid body 13 upward, or place the legs 17 on the floor 18.

For convenience, the upper and lower sides of the present invention are defined in the state of fig. 1, that is, the roller 14 side is regarded as "lower" and the handle 16 side is regarded as "upper".

Further, a display window 19 is provided in the vicinity of the telescopic handle 15, and a button 21 as an operation element 20 is provided, and the display window 19 is a window for displaying whether or not the roller 14 is locked.

In the present embodiment, the display window 19 and the button 21 are provided on the upper portion of the box main body 11, but may be provided on the upper portion of the lid 13.

Fig. 1 (b) shows an example in which the roller 14 has a double-wheel type roller.

That is, the roller 14 may be a single-wheel type as shown in fig. 1 (a) or a double-wheel type as shown in fig. 1 (b).

As shown in fig. 2, a cup member 23 that opens downward is attached to a lower corner portion of the luggage case 10, a lower opening of the cup member 23 is closed by a cover 24, a cylindrical bush 25 is fixed to the cover 24 via a bush holder 26, a rod-shaped stopper member 27 is inserted into the cylindrical bush 25 from above, and the stopper member 27 extends to the vicinity of the roller 14.

The roller 14 is rotatably attached to a swivel bracket 31, the swivel bracket 31 is supported by the cylindrical bush 25 by a flanged nut 32 screwed into a lower portion of the cylindrical bush 25, and a thrust bearing 33 is disposed between the bush holder 26 and the swivel bracket 31, so that the swivel bracket 31 swivels about the brake member 27 with respect to the stationary bush holder 26.

A pin 34 is attached to the cup-shaped member 23, a swing lever 35 is swingably supported by the pin 34, a brake member 27 is connected to one end of the swing lever 35, a wire 36 is connected to the other end of the swing lever 35, and the wire 36 extends upward from inside the cup-shaped member 23.

The wire 36 is a highly reliable and inexpensive transmission component, but is used only for pulling because it is bent and does not exhibit transmission performance when compressed.

In fig. 2, the braking member 27 is away from the roller 14 so that the roller 14 can rotate, which state is referred to as a lock release state, i.e., a free state.

When the wire 36 is pulled up as indicated by the arrow (1), the swing lever 35 rotates clockwise in the drawing, the braking member 27 descends, and when the braking member 27 contacts the roller 14, the roller 14 becomes unable to rotate, which is referred to as a locked state.

When the wire 36 is released as indicated by the arrow (2), the rocker 35 is pivoted in the counterclockwise direction in the drawing, and the braking member 27 is raised, i.e. returned to the free state.

As shown in fig. 3, the telescopic handle 15 is composed of a fixed tube 41 built in the luggage case 10, a movable tube 42 movably housed in the fixed tube 41, and a gate frame 43 housed in the movable tube 42. A claw 44 is provided at the upper end of the movable tube 42.

Note that the movable tube 42 may be omitted and the gate frame 43 may be directly inserted into the fixed tube 41, in which case the upper end of the gate frame 43 is provided with the claw 44.

In this embodiment, the horizontally long box body 45 may be integrally formed with the expansion handle 15 and the horizontally long box body 45 may be attached to the luggage case 10.

Therefore, the upper surface of the horizontally long box 45 corresponds to the general surface of the luggage case 10.

The horizontally long box 45 is provided with a button 21, and houses a relay member 46, a 1 st drive mechanism 50, and a 2 nd drive mechanism 60, which will be described later.

As shown in fig. 4, a display window 19 is provided on the front surface of the horizontally long box 45.

As shown in fig. 5, a pentagonal relay member 46 is disposed immediately below the push button 21, and the relay member 46 may be a trapezoidal plate in addition to a pentagonal plate.

A left slide-push portion 47L is formed on the left shoulder of the relay member 46, and a right slide-push portion 47R is formed on the right shoulder. At least 2 wires 36 are connected to the relay member 46.

The wire 36 extends upward from the relay member 46, and then is wound around a pulley 48 rotatably provided in the horizontally long box 45 to extend downward and reach the vicinity of the roller 14.

Further, vertically long 1 st members 51 are provided on the left and right sides of the push button 21 so as to penetrate the horizontally long box 45, and inclined 1 st sliding surfaces 52 are formed on the bottom of the 1 st members 51. A 2 nd member 53 extending in the lateral direction is disposed between the 1 st sliding surface 52 and the left sliding portion 47L (or the right sliding portion 47R), a 2 nd sliding surface 54 formed at one end of the 2 nd member 53 is in sliding contact with the 1 st sliding surface 52, and a 3 rd sliding surface 55 formed at the other end of the 2 nd member 53 is in sliding contact with the left sliding portion 47L (or the right sliding portion 47R).

The 1 st driving mechanism 50 is constituted by the 1 st member 51 and the 2 nd member 53.

In fig. 3, when the telescopic handle 15 is retracted, the 1 st member 51 is pressed down by the claw 44, and then, in fig. 5, the 2 nd member 53 on the left moves rightward, and the 2 nd member 53 on the right moves leftward, and the 2 nd member 53 lowers the relay member 46 by a sliding push action.

As shown in fig. 6, when the relay member 46 descends, the wire 36 descends at a portion outside the pulley 48, and the wire 36 ascends at a portion inside the pulley 48 (between 2 pulleys 48), and finally, the swing lever 35 rotates, the brake member 27 contacts the roller 14, so that the roller 14 becomes a locked state.

Here, it is important that a gap 56 is created between the push button 21 and the relay member 46, and by the presence of this gap 56, in fig. 6, the push button 21 can be arbitrarily depressed.

As shown in fig. 3, when the telescopic handle 15 is pulled out, the claw 44 is separated from the 1 st member 51, and then, in fig. 6, the spring 57 moves the left 2 nd member 53 to the left and the right 2 nd member 53 to the right, and the relay member 46 is lifted by the biasing force of the spring 58 to return to the state of fig. 5, and the roller 14 becomes a free state.

As shown in fig. 7 (a), the relay member 46 is printed with, for example, "FREE" and "LOCK" characters.

As shown in fig. 7 b, when the relay member 46 is at the upper position (corresponding to fig. 5), the display window 19 displays the character "FREE".

As shown in fig. 7 c, when the relay member 46 is at the lower position (corresponding to fig. 6), the display window 19 displays a character "LOCK".

Also, "FREE" may be "GO", "movable", and other words or patterns. In addition, "LOCK" may also be "STOP", or other characters or patterns.

Next, the operation of the button 21 will be described.

In fig. 5, the push button 21 and the relay member 46 are directly abutted, and in this case, the 2 nd drive mechanism 60 is constituted by the bottom surface 21a of the push button 21 and the upper edge 46a of the relay member 46 contacting the bottom surface 21 a.

Therefore, when the button 21 is manually pressed, the relay member 46 is integrally lowered.

In fig. 8, the roller 14 is in the locked state as described in fig. 6, and it is important here that gaps 56 are formed between the 2 nd member 53 and the left and right slide-pushing

portions

47L and 47R.

By the presence of the gap 56, the 1 st member 51 can be lowered to move the 2 nd member 53 laterally.

Since the Push button 21 is biased by the Push button return spring 22, the Push button 21 is lifted when the finger is released, and in this case, the Push-Push mechanism 70 is attached to the Push button 21.

As shown in fig. 9, the Push-Push mechanism 70 includes a link 71 extending from the bottom of the Push button 21, a pin portion 72 formed by bending a lower end of the link 71, and a circumferential groove 73 into which the pin portion 72 is fitted. The surrounding groove 73 is provided in the laterally long box body 45 as a stationary member.

The surrounding groove 73 is set with a button protruding position 74, a button pressed position 75, a 1 st intermediate position 76, and a 2 nd intermediate position 77 in a convenient manner.

When the push button 21 is pressed, the pin portion 72 at the push button protruding position 74 moves to the 1 st intermediate position 76; when the finger is released from the button 21, the pin portion 72 moves to the button pressing position 75.

The pin portion 72 stays at the button pressed position 75 due to the urging force by the button return spring 22; the state (locked state) of fig. 8 is maintained by the pin portion 72 staying at the button pressing position 75.

When the button 21 is pressed again, the pin portion 72 at the button pressing position 75 moves to the 2 nd intermediate position 77; when the finger is released from the button 21, the pin portion 72 moves to the button projecting position 74; this is referred to as a Push-Push mechanism 70 because of the repeated Push-presses.

Also, the surrounding groove 73 is shown enlarged for ease of understanding. The connecting rod 71 may also be a thin piano wire. Therefore, the surrounding groove 73 for practical use can take a very small shape.

The Push-Push mechanism 70 may be a Push-Push mechanism described in patent No. 5695123 invented by the present inventors, and may have any configuration.

The actions described above are listed below.

Pattern name roller of mode telescopic handle button

a pull-out reset diagram 5 free

b is in a retracted reset figure 6 locking state

c is pulled out and is pressed down to fig. 8 for locking

double locking for folding and pushing

In the table, the symbol "denotes an element that exerts a locking action.

In mode b, the telescopic handle is retracted, whereby the roller is locked.

In mode c, the button is pressed, whereby the scroll wheel is locked.

In mode d, the telescopic handle is retracted and the push button is pressed, whereby the roller is double locked. Even if a failure occurs in one of the 1 st drive mechanism (fig. 5, reference numeral 50) and the 2 nd drive mechanism (fig. 5, reference numeral 60) during locking, the locked state is maintained by the other function. By double locking, the locking of the roller is strengthened.

When the retractable handle is in the retracted state and the push button is in the pressed state (when the operation member is moved), the roller is in the double-lock state by the mode d.

When the telescopic handle is in a retracted state or when the push button is in a pressed state (when the operation member is moved), the roller is in a locked state in the mode b or the mode c.

Further, when the telescopic handle is in the pulled-out state and when the push button is in the reset state (when the operation member is in the reset state), the roller is brought into the free state by the mode a.

When the push button (movement operation member) is pressed while the telescopic handle is in the pulled-out state, the scroll wheel is in the locked state in the mode c.

Fig. 5 shows an example of a case in which the push button 21 and the 1 st member 51 are projected upward from the horizontally long box 45, and fig. 1 shows an example of a case in which a hand may hit the push button 21 to cause an erroneous operation of the push button 21 when the telescopic handle 15 is operated.

As shown in fig. 10 (d), a notch 79 is provided in the horizontally long box 45 at a position surrounding the push button 21.

As shown in fig. 10 (e), the button 21 can be pushed down by the notch 79, and finally, the upper surface of the button 21 can be made flush with the upper surface of the laterally long box 45 or can be made lower than the upper surface of the laterally long box 45. This prevents the button 21 from being erroneously operated.

Similarly, a notch is cut in a portion surrounding the 1 st member 51 as shown in fig. 10 (b).

As shown in fig. 10 (c), the claw 44 may be lowered deeper.

If the upper surface of the 1 st member 51 does not protrude from the laterally long box 45 as shown in fig. 10 (a), the appearance can be improved.

Next, a modified example of the present invention will be described with reference to fig. 11 to 13. Note that elements common to fig. 5 are denoted by reference numerals in fig. 5, and detailed description thereof is omitted.

As shown in fig. 11, the upper end of the wire 36 is connected to a horizontally long relay member 46.

The 1 st driving mechanism 50 includes a 1 st member 51 depressed by the telescopic handle and a 1 st lever 59 which is swung by the 1 st member 51 to push up the relay member 46.

The 2 nd driving mechanism 60 is constituted by an L-shaped 2 nd lever 61 which rotates when depressed by the push button 21 to push up the relay member 46.

As shown in fig. 12, when the 1 st member 51 is pressed down, the 1 st lever 59 swings, the relay member 46 rises, the wire 36 is pulled up, the brake member 27 descends, and the roller 14 is locked, and at this time, a gap 56 is generated between the raised relay member 46 and the tip of the 2 nd lever 61, and the push button 21 can be pressed down by the existence of the gap 56.

In fig. 11, when the push button 21 is depressed, the 2 nd lever 61 is rotated.

As shown in fig. 13, the relay member 46 is lifted by the 2 nd lever 61, and the roller 14 is locked as in fig. 12, and at this time, a gap 56 is generated between the lifted relay member 46 and the tip of the 1 st lever 59, and the 1 st member 51 can be pressed down by the existence of the gap 56.

Next, a modified example of the operation element 20 will be described with reference to fig. 14.

As shown in fig. 14 (a), the operating member 20 may be an eccentric circular cam 81.

As shown in fig. 14 (b), the relay member 46 can be lowered by rotating the operating element 20, which in this case corresponds to moving the operating element 20.

As shown in fig. 14 (c), the operating element 20 may be a slide button 83 having an upper slide portion 82 on the lower surface, and in this case, a lower slide portion 84 is provided on the upper side of the relay member 46.

As shown in fig. 14 (d), when the slide button 83 is moved laterally, the upper slide-pushing portion 82 presses down the lower slide-pushing portion 84, and the relay member 46 is lowered.

Since the eccentric circular cam 81 and the slide knob 83 have self-holding capability, there is an advantage that the Push-Push mechanism (fig. 9, symbol 70) is not required.

In contrast, in the push button 21 shown in fig. 1, since the retraction direction of the telescopic handle 15 coincides with the pressing direction of the push button 21, there is an advantage that there is operational commonality and there is no fear of causing an erroneous operation.

The operation element 20 may be a stick other than the push button 21, the eccentric cam 81, and the slide knob 83, and in short, is not limited to the embodiment as long as it can move the relay member 46.

The construction and operation of the operator return mechanism 90 will now be described.

In fig. 15, the roller 14 is double locked after lowering the 1 st member 51 and pressing the button 21.

Further, an operator returning mechanism 90 is disposed between the 1 st member 51 on one side (left side in the drawing) and the push button 21. The detailed configuration and operation of the operation member return mechanism 90 will be described below with reference to fig. 16.

As shown in fig. 16 (a), the operating element return mechanism 90 is constituted by, for example, a drive lever 92, a stopper 93, a rotating plate 95, a drive piece 96, a drive shaft 97, a compression spring 98, and a compression spring 99, wherein the drive lever 92 is caught on the back surface of the 1 st member 51 with a pin 91 and extends approximately horizontally toward the push button 21 side; the stopper 93 prevents the drive lever 92 from rotating downward; the rotating plate 95 has a driven piece 94 sprung up by the driving lever 92; the driving piece 96 extends upward from the rotating plate 95; the drive shaft 97 extends from the drive plate 96 to the surrounding slot 73; the compression spring 98 returns the drive shaft 97 to the standby position; the compression spring 99 returns the rotating plate 95 to the standby position.

Fig. 16 (a) corresponds to fig. 15, the 1 st member 51 is lowered and the push button 21 is pressed. A pull rod 71 extends downwardly from the push button 21, and a pin portion 72 at a lower end of the pull rod 71 is fixed in a push button pressing position 75 surrounding the groove 73.

After the telescopic handle 15 is pulled from this state, only the 1 st member 51 is lifted.

Then, as shown in fig. 16 (b), the drive lever 92 ejects the driven plate 94, and due to the ejection, the rotating plate 95 rotates clockwise in the figure, and the drive plate 96 ejects the drive shaft 97 to a large extent. The drive shaft 97 will then push the pin 72 to move to the 2 nd intermediate position 77.

As shown in fig. 16 (c), the pin portion 72 will return to the button projecting position 74. The 1 st member 51 will continue to rise beyond the driven plate 94. Then, the rotating plate 95 is returned to the standby position by the compression spring 99, and the drive shaft 97 is returned to the standby position by the compression spring 98.

Since there is no interfering object in the surrounding groove 73, the button 21 can be freely depressed.

In fig. 16 (c), after the telescopic handle 15 is compressed, only the 1 st member 51 is lowered. Accompanying this lowering, the drive lever 92 abuts against the driven plate 94, and the drive lever 92 rotates counterclockwise in the drawing as viewed from the imaginary line. Due to this rotation, the driving lever 92 will reach below the driven plate 94, returning to fig. 16 (a).

In the structure of fig. 5 and 11, in order to set the roller 14 from the double-locked state to the free state, two operations of pulling out the telescopic handle 15 and pushing down the push button 21 are required.

In principle, the storage is performed in a state where the retractable handle 15 is retracted and the push button 21 is pushed to the roller 14 locking position.

After long-term storage, the user forgets that the position of the push button 21 is at the roller 14 locking position, and pulls out the retractable handle 15, and then desires to move the luggage case 10. However, it cannot be moved or requires the button 21 to be pressed. The operation is cumbersome.

In this regard, as shown in fig. 15, if the operation returning mechanism 90 is provided, the push button 21 automatically returns to the free position of the roller 14 in conjunction with the pulling out of the telescopic handle 15, and the use is convenient.

Fig. 16 (a) corresponds to a case where the telescopic handle 15 is retracted, and at this time, the presence of the operator returning mechanism 90 does not affect the operation of the push button 21.

Fig. 16 (c) corresponds to the case where the extension handle 15 is pulled out, and in this case, the presence of the operator returning mechanism 90 does not affect the operation of the push button 21.

Further, the operator returning mechanism 90 is merely described as a good example, and the configuration may be changed as appropriate.

Furthermore, the luggage case 10 may be equipped with 4

wheels

14 and 2 wheels 14.

In the luggage case 10 equipped with 2 wheels 14, the braking means 27 is attached to 2 wheels 14.

In the luggage case 10 equipped with 4 wheels 14, braking means 27 are attached to 2 of the wheels 14; in the luggage case 10 equipped with 4 wheels 14, the brake member 27 may be attached to all 4 wheels 14.

Therefore, the utility model is suitable for a be equipped with 2 gyro wheels 14's suitcase at least.

Further, the luggage 10 includes suitcases, traveling cases, and large-sized suitcases, and is not limited to the luggage in the narrow sense. The utility model discloses be suitable for the suitcase that is equipped with the gyro wheel.

The utility model discloses a design focus lies in:

The above description is only a preferred embodiment of the present invention, and is not intended to limit the technical scope of the present invention, so that any slight modifications, equivalent changes and modifications made by the technical spirit of the present invention to the above embodiments are all within the scope of the technical solution of the present invention.
