[0001] DESCRIPTION
[0002] Locking device
[0003] The present invention relates to a closure device for orthoses, bandages or sports aids, and to an orthosis, a bandage or a sports aid comprising such a closure device.
[0004] Orthoses, bandages, or sports aids often feature a fastening device for attachment, particularly to a body part. Such a fastening device can have two locking parts that are slid into, onto, or over each other, with the two locking parts then being in a slid-in state. A snap-lock system is often used to connect these locking parts, particularly in a form-fitting and reversible manner. Snap-lock systems are known in which, for example, a locking element engages in a snap-lock receptacle, with the locking parts, and thus the fastening device, being in a connected state, particularly by means of a snap-lock connection that is reversible.To move the locking parts from a connected state back to an inserted state or a separate state, and in particular to separate the locking parts from each other, the connection, in particular a latching connection, is released by an actuating element, in particular a mechanical actuating element, and the two locking parts are moved away from each other manually, in particular by hand. In known locking devices, the two locking parts are disadvantageously moved from a connected state to an inserted state or a separate state in two steps: in a first step by actuating the actuating element and in a second step by manually moving the two locking parts away from each other.
[0005] Also known are locking devices comprising a first and a second locking part, wherein the first locking part can be inserted into the second locking part and the locking parts can be connected to each other via a locking system. One of the two locking parts has two locking hooks that engage in corresponding receptacles on the other element, wherein the outer surfaces of the two locking hooks are inclined, in particular as an inclined plane, such that after the connection, in particular the locking connection, is released, in particular due to the angle of inclination of the inclined outer surfaces of the locking hooks, the locking hooks slide out of the receptacles, in particular as if running out of the recesses by themselves. A disadvantage of such a system, however, is that the locking hooks wear out, in particular become worn, through repeated connection and release, and thereby the entire locking part becomes unusable and must be replaced.
[0006] The invention is therefore based on the objective of creating a locking device in which the aforementioned disadvantages are at least reduced, and in particular do not occur. In particular, the invention is based on the objective of creating a simple locking device that is easy to open and / or close, especially easier than known locking devices. In particular, the invention is based on the objective of creating a cost-effective and sustainable locking device.
[0007] The problem is solved by providing the present technical teaching, in particular the teaching of the independent claims as well as the embodiments disclosed in the dependent claims and the description.
[0008] The problem is solved in particular according to one aspect by creating a closure device for orthoses, bandages or sports aids, comprising a first closure part, in particular a rail, and a second closure part, in particular a rail receptacle, wherein the first closure part can be inserted into the second closure part and the first closure part and the second closure part can be reversibly connected to each other via a locking system, wherein the locking system has at least one clamping element, wherein the at least one clamping element is arranged on the first closure part and / or the second closure part, and wherein the at least one clamping element is in a pre-tensioned, in particular compressed, state in the insertion direction when the first closure part and the second closure part are connected and is elastically deformable.
[0009] According to the invention, the closure device for orthoses, bandages, or sports aids, hereinafter referred to as the closure device, comprises a first closure part, in particular a rail, and a second closure part, in particular a rail receptacle. According to the invention, the first closure part can be inserted into the second closure part, and the first closure part and the second closure part can be reversibly connected to each other via a locking system. When the first closure part is inserted into the second closure part and the first closure part and the second closure part are reversibly connected to each other via the locking system, the first closure part and the second closure part are in a connected state. With the aid of the locking system, the first closure part and the second closure part are connected to each other by means of a snap-fit connection, in particular by a positive locking connection.If the first locking part is inserted into the second locking part and the first and second locking parts are not reversibly connected to each other via the locking system, the first and second locking parts are in an inserted state. If the first locking part is not inserted into the second locking part and the first and second locking parts are not reversibly connected to each other via the locking system, the first and second locking parts are in a separated state. According to the invention, the locking system has at least one clamping element. According to the invention, the at least one clamping element is further arranged on the first and / or the second locking part. If the locking system has exactly one clamping element, the at least one clamping element is arranged on the first or the second locking part.If the locking system has more than one clamping element, in particular at least two clamping elements, the clamping elements can be arranged either on the first locking part or the second locking part, or, in particular, divided between the first and second locking parts. According to the invention, the at least one clamping element is in a pre-tensioned, in particular compressed, state in the insertion direction when the first and second locking parts are connected, and is elastically deformable. Preferably, "in a pre-tensioned state in the insertion direction" means that a pre-tension vector, which specifies the pre-tension direction, is parallel to an insertion vector, which specifies the insertion direction, or is at an angle, in particular an internal angle, of 0 to 89.9°, in particular less than 90°, and in particular not orthogonal, to the insertion vector.
[0010] In the connected state, in which the first locking part is inserted into the second locking part and the first locking part and the second locking part are reversibly connected to each other via a locking system, the at least one clamping element is in a pre-tensioned state in the insertion direction according to the invention, i.e. is pre-tensioned, in particular compressed, i.e. in particular stretched by a distance from an initial state to a clamping state, and elastically deformed.When the reversible connection, in particular the snap-fit connection, is released, for example, by applying force, between the first locking part and the second locking part via the snap-fit system, in particular when transitioning from the connected state to an inserted state or a separated state, the at least one clamping element relaxes, in particular is no longer in the pre-tensioned state, in particular is no longer pre-stressed, in particular is no longer compressed, that is to say, in particular, it returns to an initial state. The at least one clamping element is not elastically deformed in the initial state.This ensures that, depending on which locking component the at least one clamping element is located on, at least the first locking component or the second locking component moves by at least a distance corresponding to the distance from a clamped state to an initial state of the clamping element, in particular moving away from the other locking component. In this way, separating the locking components from each other, in particular the transition from the connected state to the inserted state or the separated state, requires only one step, namely, in particular, releasing the reversible connection, in particular the snap-fit connection, of the first locking component with the second locking component via the locking system. A step of manual movement, in particular moving away, of the first locking component or the second locking component from the other is unnecessary.Preferably, the first or second locking part springs open practically automatically after the locking system is actuated. Only one manual step is required to move the first and second locking parts of the inventive locking device from a connected state to an inserted state or a separated state, in particular to separate the first locking part from the second locking part, especially by means of the clamping element, which is in a pre-tensioned state. In this way, simple opening of the inventive locking device is achieved, in particular, simpler opening than with known locking devices.
