Description

"Suitcase or similar container"

The invention relates to a suitcase or similar container according to the preamble of claim 1.

Cases or similar containers are known which have more than two rollers, wheels or the like. have on which they can be driven on a surface with little effort. Conventionally, such cases or similar containers are provided with a handle part 1, so that they can be handled easily while driving and offer a comfortable point of attack for the hand of the user.

In such cases or similar containers, the wheels rotate freely on the corresponding underside of the case stored. Thus, these suitcases can start to move automatically in an undesirable manner, provided that they are parked on an inclined surface, for example an inclined treadmill. With such a movement, the case can reach speeds at which the like in the event of an impact. the suitcase itself, its contents, other items of luggage or furnishings can be damaged or, in particularly unfavorable circumstances, even people can be injured.

The invention has for its object to provide a suitcase or similar container in which there is no longer any risk of the damage or injury described above.

This object is achieved by the features in the characterizing part of claim 1. By means of the blocking device proposed according to the invention and acting as a braking device, it can be reliably prevented that the suitcase or similar container starts to move unintentionally.

A design of the blocking device which is not structurally complex and ensures safe locking of the wheels of the case or similar container results from claims 2 or 3. The blocking of the wheels can advantageously be coupled with the actuation of the handle device provided for moving the case in such a way that the case is only automatically released when the handle device is moved into its operating position by the user for moving the case. If the handle device is in its rest position, the wheels are reliably blocked. In this embodiment, there is no additional operating effort for the actuation of the blocking device.

The connection between the handle device and the blocking device can be realized in a structurally particularly simple and particularly reliable manner in terms of functional reliability.

By means of the spring devices arranged and designed according to claim 6 or 10, a reliable functioning of the blocking device can still be guaranteed in a mechanically simple manner even after a long period of use of the case. The adjustments required for blocking within the blocking device are carried out quasi without external influence exclusively by internal actuating processes. Due to the advantageous embodiment of the handle device provided with claim 7, with which a rigid connection between the handle and the case is achieved, the case can be moved safely and easily without the risk of tipping over when the direction changes; furthermore, reliable actuation of the blocking device by the handle device can be ensured with less design effort.

According to claim 8, the handle device can be held reliably in its rest position, whereby a locking of the wheels is achieved at the same time, unless a method of the case is intended.

Due to the design of the handle according to claim 9, a blocking and release of the handle device and thus the blocking device is possible without any additional handles.

According to claim 11, the advantages of the blocking device according to the invention can also be used in conjunction with movable suitcases, the handle device of which is designed as a pull handle with a belt strap.

By equipping several wheels with the blocking device according to claim 12, the operation Safety of the mobile case can be increased even further.

This applies in particular when wheels provided with locking devices are located near both the rear and the front ends of the case, since then a pushing movement of the case, which starts from rolling axles not provided with at least one blocking device, is reliably avoided.

The design of the wheel-side components according to claim 14 results in an advantageous and protected attachment of the wheel to the case on the one hand, and on the other hand a technically simple arrangement of the first spring device and the locking part blocking the wheel.

As a result of the displaceable fixation of the locking part on the bearing block specified in claim 15, canting etc. of the locking part, which could lead to the inoperability of the blocking device, can be reliably avoided.

A reliable engagement between the locking part and the wheel arises if the measures specified in claim 16

Engagement between the locking part and the wheel can be produced and released in a simple manner. According to claim 17 can be made possible that the wheel is steerable.

By the measures specified in claim 18 it can be ensured that the wheel is put into a position in which its direction of rotation is not arranged parallel to the direction of travel each time the case is moved or raised without guidance, thereby preventing undesired movement of the case becomes.

According to claim 19 it can be ensured that the wheel, unless there is a guided movement of the case, is fixed in a position in which its direction of rotation is arranged perpendicular to the running direction.

By means of the measures specified in claim 20, the bearing block and thus the wheel can be blocked in the position perpendicular to the running direction when the handle or the handle are in their rest position.

With the configuration specified in claim 21, the wheel can be mounted in a technically uncomplicated manner, in which the wheel can be freely steered in all directions, but is nevertheless ensured. that the wheel in one Position can be fixed in which its direction of rotation is arranged perpendicular to the direction of travel. When lifting the case or rolling it without a handle, the wheel turns sideways. When the handle or handle is at rest, the wheel is locked in this transverse position.

The connection between the gate valve and the bearing block can be realized in a simple manner according to claim 22. the curve piece can then be fixed in the locking slide and, if it is not fixed by the locking slide, can be freely rotated.

A particularly good movement of the locking slide in the housing results according to claim 23.

A case 11 is provided with wheels 14 near its front end and with wheels 18 near its rear end. On these wheels 14, 18, the case 11 is movable on a surface, not shown. For this purpose the

Case 11 in the upper region of its front end wall 10 is provided with a handle device, to which a saange 1 and a handle or a handle 5 belong. The rod 1 is in the vertical direction between an extended position in which it, as shown in Figure 1. protrudes upwards from the case, and an inserted position in which, as shown in FIG. 2, it is received within the case 11. adjustable. A pawl 15 is articulated near the upper end of the rod 1, which in the pushed-in position of the rod 1 engages with an engagement member 9 formed on the upper part of a receptacle 8 for the rod 1 and thus blocks the rod 1 in its inserted position.

At the upper end of the rod 1, the handle 5 is pivoted. In the inserted position of the rod 1, the handle 5 is pressed by means of a torsion spring 22 arranged between the rod 1 and the handle 5 into a position in which it is arranged as close as possible and in alignment with the contour of the case 11.

Another section of the torsion spring 22 presses the pawl 15 into its blocking position, in which it engages with the engagement member 9. A shoulder 16 is integrally formed on the handle 5, by means of which the pawl 15 can be brought out of its blocking position into a release position when the handle 5 is pivoted. At the other, ie lower end 2 of the rod 1, it is in its inserted position in contact with a slide 3; this is also movable in the vertical direction with respect to the case 11. The slide 3 is acted on from its rod-distant side by a spring device 4 supported in the receptacle 8, by means of which the slide 3 is pressed against the lower end 2 of the rod 1.

On its side remote from the rod, two cables 6 and 17 are attached to the slider 3. The cable 6 acts in connection with the front wheel 14, the cable 17 in connection with the rear wheel 18. Since the components provided between the cable 6 and the wheel 14 in terms of their design, function and effect, those between the cable 17 and the Correspond to wheel 18, only the components provided between the cable pull 6 and the front wheel 14 are described below.

At its end remote from the slider, the cable 6 is connected to a blocking device 12 designed as a bolt. The bolt 12 is slidably arranged in a receptacle 23. Between an inner end wall of the receptacle 23 and the opposite end wall of the bolt 12, a spring device 7 is arranged, which biases the bolt 12 out of the receptacle 23 in the direction of the front wheel 14 of the case 11. The bolt 12 is on its outer end face provided with a projection 25.

The front wheel 14 is formed on its end face opposite the bolt 12 near its outer circumference with a recess 13; in the direction of this recess 13, the projection 25 of the bolt 12 is pressed by the first spring device 7 when the recess 13 and the projection 25 are aligned with one another.

The second spring device 4 is designed to be stronger than the first spring device 7, so that the bolt 12 can only be pressed into the recess 13 with its projection 25 when the slide 3 through the lower end 2 of the rod 1 against the force of the second spring device 4 is adjusted downwards.

The interaction of the components explained above is described below:

To move the case 11, the handle 5 against the

Force of the torsion spring 22 pivoted away from the case 11 or from the rod 1. After pivoting the handle 5 by a certain angle, the shoulder 16 formed on the handle 5 comes into contact with the pawl 15 and releases it - with continued pivoting of the handle 5 - from it Engagement with the engagement member 9. After the adjustment of the pawl 15, the rod 1 can be pulled out of the receptacle 8 in the vertical direction into the extended position shown in FIG. As a result, the lower end 2 of the rod 1 is removed from the slider 3. The latter is shifted upwards by the second spring device 4 against the lower force of the first spring device 7, which acts in opposite fashion at the end of the cable pull 6 remote from the sliding piece. During this upward displacement of the slider 3, the cable 6 is pulled upward so that it removes the bolt 12 from the wheel 14. The projection 25 of the bolt 12 and the recess 13 provided on the wheel 14 disengage; the wheel 14 is now freely rotatable. The case 11 is ready to drive.

In order to bring the handle 5 back into its rest position, the rod 1 is moved downwards into its inserted position. The torsion spring 22 moves the handle 5 in its position against the case 11. During this pivoting, the system between the shoulder 16 and the pawl 15 is lifted so that the latter is put back into its blocking position by the torsion spring 22, in which position it engages with the engagement member 9.

During its downward movement, the rod 1 presses with its un Lower end 2, the slider 3 against the force of the second spring device down. As a result, the cable 6 is relaxed. The game resulting from this relaxation is immediately converted into a displacement of the bolt 12 in the direction of the wheel 14 by the force of the first spring device 7. As soon as the recess 13 in the rotating wheel 14 is aligned with the projection 25 of the bolt 12, the engagement between the projection 25 and the recess 13 is established by the first spring device 7. The wheel 14 is then blocked. An undesirable rolling of the case 11 is excluded.

The second exemplary embodiment shown in FIGS. 4 and 5 differs from the first exemplary embodiment described above as follows:

A second spring device 24 biases the slider 3 downward into a position in which the components provided between the slider 3 and the wheel 14, which correspond to those of the first exemplary embodiment, cause the wheel 14 to lock.

The slider 3 is connected to a webbing 19 which is biased by a spring 21. The webbing 19 by pulling on a handle 20 connected to it from the Case 11 pulled out, it adjusts the slide 3 against the force of the second spring device 24 upwards during the last section of this movement. This upward movement of the slider 3 - as described in connection with the first embodiment - pulls the bolt 12 via the cable 6 into a position releasing the wheel 14.

When the webbing 19 is relieved and pulled back into the case, the second spring device 24 presses the now relieved of the webbing 19 slider 3 with the result that - as described in connection with the first embodiment - the engagement between the

Bolt 12 and the wheel 14 is restored.

FIGS. 6a-6c show a second embodiment of the wheel-side components of the blocking device which are connected to the slider 3 by means of the cable 6 shown in FIGS. 6b and 6c. At the wheel end of the cable 6, a locking part 30 is attached. This locking part 30 is configured on its side end walls with projections 34 which are formed in a U-shaped bearing block 26

Engage elongated holes 32 and are guided in a vertical direction. The first spring device 7 is arranged between the bearing block 26 and the locking part 30, that it biases the locking member 30 downward so that it engages in recesses 28 formed in flanges 29 which are formed or arranged on both sides of the wheel 14. The locking part 30 is designed with a central recess 35, in which the section of the wheel 14 arranged above the base of the recesses 28 into which the locking part 30 engages can be received. The locking part 30 is always in blocking engagement with the cutouts 26 when the handle or the handle 5 of the case 11 is in its rest position. If the handle or the handle 5 is brought into the operating position, the cable 6 is pulled away from the wheel 14 by the second spring device 4 so that it raises the locking part 30 against the force of the first spring device 7 to such an extent that the locking engagement between the locking part 30 and the recesses 28 are canceled and the wheel 14 is thus rotatable. The wheel 14 is rotatably received at the free ends of the legs of the U-shaped bearing block 26, which in turn is partially received or sunk in a housing 27, which is fastened to the case 11 and is not shown and is open at the bottom.

The bearing block 26 can, as shown in Figure 6b, be arranged in the housing 27; it is also possible, as shown in FIG. 6c, to pivot the bearing block 26 in the housing 27 in order to enable a change in direction of the wheel 14 A ball bearing 33 is then arranged between the base of the U-shaped bearing block 26 and a bearing part 31 attached to the housing 27 and the bearing block 26 is rotatable about a hub part 36 attached to the housing 27, the inside of which holds the upper end of the first spring device 7 is formed.

Also in the embodiment of the wheel or roller-side components of the blocking device shown in FIGS. 7a to 7d, the approximately U-shaped bearing block 26 is accommodated in the housing 27 so as to be rotatable or pivotable. The first spring device 6 is designed as a helical spring and is attached with one end to the bearing block 26 and with its other end to the housing 27 in such a way that it prestresses the bearing block 26 or the wheel 14 in a position perpendicular to the running direction, as shown in FIG. 7b is. In this position, a stop edge 37 formed on the bearing block 26 strikes against a stop edge 8 formed on the housing 27, so that egg white rotation of the bearing block 26 in the housing 27 is prevented. In this position of the Lagerbockε 26, a recess 40 which is formed in the bearing block 26 is arranged such that an angle lever 39, which is pivotably articulated on the housing 27 and biased by means of a spring 45 in the direction of its position engaging in the recess 40 intervenes. When establishing the engagement between the angle lever 39 and the recess 40, the wheel 14 or the U-shaped bearing block 26 is blocked in the position shown in FIGS. 7b and 7c, in which the wheel 14 is arranged perpendicular to the running direction. If the handle or the handle 5 is brought into the operating position, pulling the cable 6, which is carried out by the second spring device 4, causes the angle lever 39, to which the wheel-side end of the cable 6 is fastened, against the force of the spring 45 pivoted away from the bracket 26 so that it no longer engages in the recess 40 formed in the bracket 26. The blocking of the wheel 14 in the position perpendicular to the direction of travel is released. The bearing block 26 and the wheel 14 can now assume a position parallel to the direction of travel when the case 11 is traveling against the force of the first spring device 7. When the case 11 is lifted or after it has only been driven for a short time without guidance on the handle or on the handle 5, the wheel 14 is positioned transversely due to the action of the first spring device 7; when the handle or the handle 5 is inserted, the cable 6 is relieved, the angle lever 39 pivots into the recess 40. The bearing block 26 or the wheel 14 is then locked in the transverse or blocking position.

A fourth embodiment of the wheel-side components of the blocking device is shown in FIGS. 8a to 8d. The cable 6, as in the above described leadership forms with the slider 3, not shown, is at its wheel-side end on a ratchet

42 attached. The locking slide 42 is biased by two springs 44, which form the first spring device, so that it receives and fixes a cam part 43 in a recess 46 formed in the locking slide 42 and adapted in terms of its shape to the cam part 43. In the curve part

43, a vertical development 41b of an angle lever 41 is fixedly attached. At the other end is the angle lever

41 designed with a further vertical development 41 a, which extends at right angles to the curve Isei term processing 41 b and is fixed in the housing 27 rotatable or pivotable bearing block 26. When the curve part 43 is caught and fixed in the recess 46 of the locking slide 42, which is always the case when the springs 44 can move the locking slide 42 onto the curve part 43, the development 41b of the angle lever 41 fixed in the curve part 43 is in the running direction arranged. Then the development 41a of the angle lever 41 fixed in the bearing block 26 and the wheel 14 are arranged perpendicular to the running direction, since the development 41a extends parallel to the direction of rotation of the wheel 14. The wheel 14 is accordingly blocked perpendicular to the running direction and cannot be rotated in the running direction.

To ensure that the curve piece 43 at the by Springs 44 caused, toward the cam piece 43 to move the locking slide 42 in its recess 46, the recess 46 has a comparatively large opening area, and the locking slide 42 is designed with two projections 47, 48 pointing away from the springs 44, which in the event of a displacement of the locking slide 42 toward the curve piece 43, if necessary, they come into contact with the eccentrically arranged end of the curve piece 43 and force the latter into a position in which it can be received in the recess 46.

If, when adjusting the handle or the handle 5 from the rest position into the operating position, the slider 3 is displaced by the second spring device 4 and is thus pulled away from the wheel 14 according to the cable 6, the locking slide 42 becomes against the force of the springs 44 is less than that of the second spring device 4, away from the curve part 43, until the curve part 43 comes out of the recess 46 of the locking slide 42. When the case 11 moves in the running direction, the wheel 14 can now be pivoted freely so that its direction of rotation of the case 11 is arranged. When lifting the case 11 and when rolling the case 11 without guidance on the handle or on the handle 5, the wheel 14 is positioned transversely due to the action of the springs 44 and is pushed into the rest position by inserting the handle or the handle 5 locked this transverse position, since the curve part 43 is then caught and fixed in the recess 46 of the locking slide 42.
