Definitions

  • the invention relates to a backpack or school bag with shoulder straps that can be or are attached to the outside of a rear wall of the backpack or school bag by means of an adjusting device, wherein the adjusting device has a housing with a substantially rectangular basic shape with a lower housing part and a housing cover, wherein the lower housing part has longitudinal guide webs that protrude into the interior of the housing and form a rail along which a slide can be moved and locked, which is indirectly connected to the shoulder straps by means of a carrier plate and which moves these in different positions together with the slide along the rail between two end positions or locks them to parts of the housing, wherein the adjustment and/or locking is made possible by a locking element that can be adjusted from a locked position to a release position and vice versa, wherein in the release position the slide can be adjusted inside the housing and the carrier plate outside the housing cover, wherein the adjustment takes place along slot-like recesses formed in the housing cover, wherein the adjusting device (1) together with the slide, the carrier plate and the locking element is arranged on the outside
  • the backpack or school bag In order to enable the backpack or school bag to be carried ergonomically and comfortably by a wearer, it usually has two shoulder straps that can be put on and carried on the back of a wearer. These shoulder straps are brought closer together in their upper end area and are connected directly or indirectly. An adjustment device is arranged in this connection area that enables the height of the shoulder straps to be adjusted relative to the backpack or school bag. Such a height adjustment serves in particular to adapt the backpack or school bag to the height of a wearer by setting the height relative to the shoulder straps that matches the height.
  • Adjustment devices of a similar type are known in various designs in the prior art.
  • the De 10 2014 006 194 A1 a first adjustment device of a similar type is known, in which which allows height adjustment by operating an operating element which moves a deformable spring locking element from a blocking position to a release position and vice versa.
  • the spring locking element fixes the slide to a locking rail and in a release position the spring locking element releases the slide relative to the locking rail so that it can be moved relative to the locking rail.
  • the control element of this adjustment device is located on the outside of the back of the backpack or school bag, facing the wearer's back. It can be operated using a coin, for example, and the adjustment device can be moved from a release position to a blocking position and back.
  • the adjustment can only be carried out in a position in which the backpack or schoolbag is not on the wearer's back, as access to the control element, which is located on or on the adjustment device, would be covered by the wearer's back in this carrying position.
  • the present invention is based on the object of creating a backpack or school bag of the type mentioned at the outset, in which a height adjustment is possible by actuating the adjustment device even while the bag is in the carrying position on the back of a wearer, which is inexpensive and easy to manufacture and has a long service life and allows adjustment by the wearer without the aid of tools or other aids.
  • the locking element is formed by a rack which is arranged approximately centrally within the housing between two longitudinal guide webs, which has an actuating element arranged outside the housing and accessible there, by means of which the rack can be adjusted between a first locking position, in which teeth formed on the rack engage in recesses formed on the slide and lock the slide in this position, and a second release position, in which the teeth do not engage in the recesses, and back into the locking position by turning, so that an adjustment of the slide along the housing is possible, whereby a height adjustment of the shoulder straps compared to the adjustment device arranged on the back of the backpack or school bag is also possible when the backpack is being used on the back of a wearer.
  • a backpack or schoolbag with such an adjustment device according to the invention can also be adjusted in height quickly and easily when the backpack or schoolbag is being carried, i.e. while the backpack or schoolbag is on the back of a wearer.
  • the wearer simply wraps his or her own body around the backpack or schoolbag in order to feel for and grasp the control element arranged above or below the carrier plate connected to the shoulder straps.
  • the control element With his or her fingers, he or she can easily swivel it manually from the locked position to the released position.
  • the slide can now be moved together with the carrier plate located on the shoulder straps in order to move the position of the backpack on the wearer's back to a desired height as desired. Once the desired height has been reached, the wearer manually swivels the control element back into its locked position so that this position can be maintained permanently.
  • teeth of a rack which in the locked position are engaged in recesses formed on the slide, are released by operating the control element, so that the slide together with the carrier plate, which is arranged on the shoulder straps so that the slide can be moved as desired within the housing and the carrier plate with the shoulder straps attached to it can be moved outside along the housing cover.
  • the operating element rotates the rack together with the teeth back into a position in which the teeth of the rack are in the recesses formed on the carriage, i.e. they engage in them, and lock the carriage and the carrier plate with the shoulder straps attached to it in this position.
  • the adjustment device thus enables height adjustment at any time in a particularly simple and comfortable manner, even when the backpack or school bag is being carried, i.e. when the backpack or school bag is on the wearer's back, without having to remove the backpack or school bag from the shoulders.
  • such a solution formed by a rack with teeth that engage with the carriage, represents a particularly cost-effective and easy-to-manufacture solution, while also being particularly robust and durable.
  • the rack has a cylindrical shape and several teeth are arranged on the rack so as to protrude approximately vertically, wherein the respective distance between two adjacent teeth and the recesses formed on the carriage is the same size.
  • a rotatable mount on housing parts is particularly easy to implement and enables a high number of adjustment processes without wear.
  • the distance between the teeth and the corresponding recesses on the slide allows for almost continuous height adjustment, especially when the distance between adjacent teeth and corresponding recesses is small.
  • the actuating element is arranged at the first end or at the second end or at the first and second ends of the rack.
  • an actuating element can also be arranged at both the first end of the rack and the second end of the rack.
  • the rack or the actuating element is held in the locking position against the force of a spring.
  • the actuating element is arranged orthogonally to the adjustment direction of the carriage, the carrier plate and the rack.
  • control element Due to the orthogonally protruding positioning of the control element, it can be recognized and grasped by the wearer in a particularly simple manner by pressing buttons, even when the backpack or school bag is on his back.
  • the housing cover is detachably connectable or connected, for example by means of clipping or hooking, to a locking plate arranged on or in the rear wall of the satchel or backpack or to the housing base or to the locking plate and the housing base.
  • the locking plate is arranged in a non-detachable manner inside the satchel or backpack on its rear wall.
  • the locking plate can be attached or arranged detachably or permanently to the back wall.
  • each carrier plate is permanently connected to the shoulder straps, in particular sewn, screwed, riveted or glued.
  • the carrier plate can also be permanently connected to the shoulder straps in the area where the shoulder straps meet.
  • this permanent connection is usually made by sewing.
  • screwing, riveting or gluing can also be considered.
  • the figures show an adjustment device 1 which can be attached to a school bag 13 or a backpack not shown in the figures with shoulder straps 14 on the outside of the rear wall ( Figure 1 to 3 ) or attached ( Figure 4 ) is.
  • the adjustable device 1 has a housing with a substantially rectangular basic shape.
  • the housing consists of a housing base 2 and a housing cover 3.
  • the housing base 2 has longitudinal guide webs 4 that protrude into the housing interior. These guide webs 4 form a rail along which a carriage 5 can be moved and locked in the desired position.
  • the carriage 5 is connected to the shoulder straps 14 by means of a carrier plate 6 or, as in Figure 4 visible, connectable.
  • a displacement of the slide 5 together with the carrier plate 6 and the shoulder straps 14 of the school bag 13 attached to it thus causes a height adjustment of the shoulder straps 14 relative to the school bag 13 or in particular relative to its rear wall.
  • This serves to adjust the height of the school bag 13 according to the size of the wearer of the school bag 13, so that a comfortable and ergonomic height is possible even when wearing such a school bag 13 over a longer period of time.
  • the locking is carried out by a locking element which can be adjusted from a locked position to a released position and vice versa. This makes it possible to lock the school bag 13 or the shoulder straps 14, which have been adjusted in terms of height, in the adjusted position in order to prevent further unwanted adjustment.
  • the slide 5 is generally adjusted together with the carrier plate 6, with the carrier plate 6 being arranged outside the housing of the adjustment device 1 and the slide 5 being arranged inside the housing of the adjustment device 1.
  • the adjustment takes place along slot-like recesses 7 formed in the housing cover 3.
  • the locking element is formed by a rack 8 which is arranged approximately centrally within the housing between two longitudinal guide webs 4.
  • the rack 8 is adjustable by means of an actuating element 9 arranged outside the housing and accessible there. The adjustment takes place between a first locking position in which the teeth 10 formed on the rack 8 engage in recesses formed on the slide 5 and lock the slide 5 in this position, and a second release position in which the teeth 10 of the rack 8 do not engage in the recesses 11.
  • the adjustment in the opposite direction is also possible in a simple manner.
  • the wearer of the school bag 13 or backpack only has to grasp the actuating element 9 by hand and turn it slightly in order to pivot the rack 8 between the locking position and the release position.
  • the slide 5 together with the carrier plate 6 and, if applicable, the shoulder straps 14 attached to the carrier plate 6 can be adjusted in a simple manner.
  • the wearer only has to manually adjust the rack 8 back into the locking position by turning the actuating element 9, so that the height once set is maintained at all times in this position and undesirable height adjustment is effectively prevented.
  • the height adjustment of the shoulder straps 14 relative to the adjustment device 1 arranged on the back part of the school bag 13 is made possible by an actuating element 9 according to the invention, which adjusts a rack 8 according to the invention, even in a position in which the school bag 13 or the backpack is on the wearer's back.
  • the school bag 13 or the backpack therefore does not have to be removed from the back in order to adjust the height of the shoulder straps 14.
  • the rack 8 has a cylindrical shape, with several teeth 10 arranged on the rack 8 so as to protrude approximately vertically.
  • the respective distance between two adjacent, i.e. consecutive teeth 10 and the recesses 11 formed on the slide 5 is the same.
  • the size of the teeth 10 corresponds to the size of the recesses 11, so that the teeth 10 are suitable for engaging in the recesses 11 and being arranged there in an approximately form-fitting manner.
  • the actuating element 9 is arranged at the upper end of the rack 8.
  • the actuating element 9 can also be arranged at the lower end of the rack 8, i.e. the end opposite the upper end, or can be arranged at both the first and the second end of the rack 8. This ensures that the actuating element 9 can be accessed at all times, depending on the height of the wearer.
  • the rack 8 and thus the actuating element 9 attached to the rack 8 is held in the locking position or arresting position against the force of a spring. This ensures that after adjustment has been made, the rack 8 and in particular its teeth 10 pivot back into the locking position and remain there permanently. This effectively prevents accidental or unwanted adjustment of the position once it has been set.
  • the actuating element 9 is arranged orthogonally projecting from the rack 8.
  • the housing cover 3 is detachably connected or connectable by means of clips to two locking plates 12 arranged on the rear wall of the school bag 13 and fastened there.
  • the locking plate 12 or the locking plates 12 are permanently fastened to the rear wall of the school bag 13 and, if necessary, covered there with covering material.
  • each carrier plate 6 is permanently connected to the shoulder straps 14; this connection is usually made by sewing, screwing or riveting. Gluing is also possible here.
