Description

The invention relates to a locking system according to the preamble of claim 1.

Such locking systems comprise a support element and at least one receiving rail. The support element is particularly advantageously designed in the form of a rod that can be fixed between two receiving rails. A locking system designed in this way can be used particularly advantageously for sports equipment systems, in particular for course sports in the indoor and outdoor area. In the simplest case, the sports equipment system has two box-shaped standing devices, between which sports equipment is attached. The sports device is formed by a rod on which people can perform different sports exercises. The mounting rails to which the bar can be attached are located on the sports equipment.

Such a sports equipment system is from DE 10 2011 116 708 A1 known. In this sports equipment system, box-like standing devices are provided, with a largely rigid sports device such as a gymnastics bar being able to be attached between two standing devices. For this purpose, the sports device has a fastening unit at its two ends.

The invention is based on the object of providing a locking system of the type mentioned at the beginning, which has a high level of functionality with little structural effort.

To solve this problem, the features of claim 1 are provided. Advantageous embodiments and expedient developments of the invention are described in the dependent claims.

The invention relates to a locking system with a support element and at least one arrangement of receiving segments having receiving rails. At one end of the support element there is provided a locking head with a connection element, which is movably mounted therein. A locking element is assigned to the locking head, and when the locking element is unlocked, the connection element is extended beyond the end of the support element and can be positioned in a receiving segment of the receiving rail. When the locking element is locked, the connection element is fixed in the receiving segment.

The locking system according to the invention is easy to handle and has a high level of functional reliability.

The locking head can be freely selectable fixed to any receiving segment of the receiving rail with a connection element, so that the position of the support element can be freely selected on the receiving rails.

It is also advantageous that, by unlocking the locking element, the connection element can be brought into a defined position protruding beyond the end of the support element, in which the connection element can be fixed to a freely selectable receiving segment. By subsequently locking the locking element, the connection element is then fixed in the receiving segment, so that the support element is securely held on the receiving rail.

The locking system designed in this way can be used in different applications. One area of application is the use of the locking system for sports equipment that is used, for example, in sports parcours, sports and fitness studios or in gymnasiums and sports halls. A simple example is sports equipment for the course area that have two or more standing devices on which mounting rails of the locking system are fixed. A support element is then installed between two standing devices as a sports device, for example as a rod for performing sports exercises, with the at least one locking head being fixed to a receiving rail of a standing device for this purpose.

Further areas of application for the locking system according to the invention are industrial applications in the areas of transport and logistics, wherein the locking system can in particular also be designed as a securing system, in particular a load securing system. The closure system according to the invention can also be used in the health sector, for example in physiotherapy.

According to an advantageous embodiment, the receiving rail has a row arrangement of identically designed receiving segments extending in its longitudinal direction.

The receiving segments thus form a linear arrangement, with the connection element of the supporting element being able to be fixed in a freely selectable manner on one of the receiving segments of the receiving rail for positioning the support element on the receiving rail.

For this purpose, the receiving segments particularly advantageously form openings into which the connection element can be inserted.

This results in a particularly good functional adaptation to the locking head of the support element. After unlocking by means of the locking element, the connecting element extended beyond the end of the support element can be positioned on a receiving segment by inserting the connecting element into the opening of this receiving segment. As soon as the connection element is inserted into the opening, it is simply secured in position there by locking the locking element.

In principle, a locking head is only provided at one end of the support element in order to fix the support element on a receiving rail. In this case, the support element can be fixedly or detachably connected to another fastening device at the other end.

Particularly advantageously, the support element has a locking head at each longitudinal end, the connection element of which can be positioned in a receiving segment of the respectively assigned receiving rail.

In this case, the receiving rails and the locking heads are expediently of identical design.

Due to the identical design of the locking heads and the mounting rails, a high degree of variability is achieved, since support elements with their locking heads can be fixed to any desired mounting rails.

Furthermore, the system formed in this way is favorable in terms of production technology, since the number of parts and variants can be kept low by using the same locking heads and mounting rails.

The support element can have any shape so that the locking system is adapted to different applications. The support element is particularly advantageously formed by a rod.

The rod can then be a load handling device if the locking system is, for example, a securing system or a load securing system. On the other hand, the rod can be used for performing sports exercises if the locking system is part of a sports device or a sports device system.

According to a structurally advantageous embodiment, the or each locking head is mounted displaceably in the axial direction by means of a ball bearing in a locking ring.

A low-friction axial displaceability of the locking head in the support element is thus achieved in a particularly simple manner.

The locking head is also advantageously resiliently mounted in the locking ring.

When the locking element is unlocked, the connecting element of the locking head is pushed out of the locking head by means of the spring force of a spring via a front opening of the locking ring.

A high level of operating convenience is thus achieved in such a way that when the locking element is unlocked, the locking head is automatically pushed out of the support element by the spring force of the spring, so that the connection element protrudes beyond the support element.

According to an advantageous embodiment, the or each locking head is connected to the support element via a connecting piece.

The locking element is mounted in bores in the connecting piece and the locking ring.

With the connection piece, on the one hand, a coupling of the locking head and its axial guide to the support element is realized. In addition, the connecting piece forms an element for guiding the locking element. This dual function of the connecting piece enables a particularly simple construction of the support element.

The locking element is particularly advantageously designed in the form of a pin.

The locking element has a resiliently mounted actuating element. The locking element can be unlocked by actuating the actuating element.

The pin-shaped locking element only takes up a small amount of space and can thus be integrated into the support element in a space-saving manner. The actuating element can be easily operated by simply pressing it to unlock the locking element. The resilient mounting of the actuating element ensures that it automatically returns to the starting position after actuation, so that it is immediately ready for use for a further unlocking process.

According to a particularly advantageous embodiment of the invention, a telescopic mechanism is assigned to the locking head or to a locking head.

In this way, the length of the support element can be adjusted in discrete steps or continuously in order to adapt it to application-specific requirements. In particular, the telescopic mechanism can be used to adjust the length of the support element in such a way that the connection element of the locking head of the support element can be brought into engagement with the receiving rail, which is typically fixedly mounted on a device.

This advantage comes into play particularly when the support element, which is designed in particular in the form of a rod, has a locking head at both ends on the longitudinal side, each of which is intended to be brought into engagement with a receiving rail. The length of the support element can then be easily and quickly adjusted to the distance between the mounting rails by means of the telescopic mechanism.

The connecting piece assigned to the locking head is particularly advantageous, a telescopic element which is part of the telescopic mechanism.

Since the connecting piece thus also takes on the function of a support element, there is a further simplification of the construction of the support element.

The telescopic element is also advantageously supported in a continuously adjustable manner in a socket. In this case, the telescopic element is mounted displaceably in the axial direction with little play in the socket.

The socket is firmly connected to the support element, in particular the rod. The telescopic mechanism is implemented by simply shifting the telescopic element, that is to say the connecting piece, in the socket, whereby a preferably stepless length adjustment of the support element is made possible in a particularly simple manner. Since the telescopic element is guided in the socket with little play, no separate fixing means are required to hold the telescopic element in a set position in the socket.

• 5 : Components according to the arrangement 4th in an exploded view.

1 shows the components of an embodiment of the locking system according to the invention 1 . The locking system 1 comprises a rod as a support element 2 with a tubular rod body 2a , at the longitudinal ends of each a head part 3a , 3b is stored.

Every headboard 3a , 3b is a mounting rail 4th as a further component of the locking system 1 assigned.

As 2 shows, shows the mounting rail 4th a linear arrangement of identically designed, equidistantly arranged receiving segments 5 on. For the formation of the receiving segments 5 has the mounting rail 4th two parallel strips 6th with a regular arrangement of recesses, which become circular receiving segments 5 add to.

The bars 6th are at a distance from the rear wall 7th the mounting rail 4th arranged. The recording segments 5 thus form openings as accesses to the space between the strips 6th and the back wall 7th .

On the front face of each headboard 3a , 3b there is a connection element 8th that is used to fix it in the mounting rail 4th in a receiving segment 5 can be introduced, the connection element 8th in its shape to the contour of the receiving segment 5 is adapted.

As the recording segments 5 the mounting rail 4th are formed identically, the connection element 8th each headboard 3a , 3b into any recording segment 5 the assigned mounting rail 4th be introduced, reducing the position of the rod 2 on the mounting rails 4th is freely selectable.

The mounting rails 4th are fixed to devices not shown. The devices can be formed, for example, by standing devices of a sports equipment system, with the rod 2 then forms a piece of sports equipment for performing sports exercises.

The longitudinal axes of the mounting rails advantageously run 4th on the stand fixtures in the horizontal direction. In principle, the longitudinal axes of the mounting rails 4th also run at angles of inclination to the horizontal.

The headboards 3a , 3b are at the longitudinal ends of the rod body 2a stored. While the headboard 3b firmly to the pole body 2a connected is the headboard 3a to the pole body via a telescopic mechanism 2a coupled. This allows a length adjustment of the rod 2 done so that the length of the rod 2 the distance between the mounting rails 4th is adapted.

The components of the telescopic mechanism are in 3 shown.

This comprises a hollow cylindrical socket made of plastic 9 that are firmly attached to the pole body 2a connected is.

There is also a telescopic element 10 provided, which is formed by a connector, which the head part 3a with the rod body 2a connects. The telescopic element 10 has a cylindrical body 10a and an end piece 10b whose outside diameter is larger than the diameter of the base body 10a , on.

Furthermore, the base body 10a of the telescopic element 10 in the axial direction in the socket 9 be moved, whereby a length adjustment of the rod 2 takes place so that it is between two mounting rails 4th is held.

Here is the main body 10a of the telescopic element 10 with little play in the socket 9 out, so that by contact or frictional forces of the base body 10a stable in the socket 9 is held. After an axial adjustment of the base body 10a in the socket 9 this no longer needs to be fixed with separate fixing means.

For mounting the rod 2 First, the telescopic mechanisms are retracted between two standing devices, so that the rod 2 can be easily introduced with sufficient play between the standing devices.

Then the user selects which of the recording segments 5 the opposite mounting rail 4th the pole 2 should be attached. These selected recording segments 5 of the two poles 2 are of course exactly opposite, so that the longitudinal axis of the attached rod 2 perpendicular to the longitudinal axes of the mounting rail 4th runs.

For fastening the rod 2 The connection elements are then attached to the stand fixtures 8th the headboards 3a , 3b in engagement with one receiving segment each 5 a mounting rail 4th brought.

the 4th and 5 show the elements of the headboard 3a the pole 2 , whereby 4th shows these components in the assembled state and 5 shows the individual components in an exploded view.

the 4th and 5 show the connecting piece forming the support element as a coupling element between the rod body 2a and headboard 3a . Even with the headboard 3b Such a connector can be provided, but not as part of a telescopic mechanism. Otherwise the headboards are 3a , 3b constructed identically.

The headboard 3a has a locking head 11 on, which is designed in the form of a rotationally symmetrical solid part. At the front end of the locking head 11 is the connection element 8th intended.

The locking head 11 is displaceable in the axial direction in a hollow cylindrical centering piece by means of a ball bearing 12th stored. The ball bearing is made up of two balls 13th formed in holes 14th the outer surface of the centering piece 12th are stored. At the front end of the centering piece 12th there is an outlet opening 15th , via which the connection element 8th is extendable.

To form a spring mounting of the locking head 11 are a disc 16 and a coil spring 17th at the rear end of the locking head 11 stored.

The end piece 10b of the connecting piece encloses the rear part of the centering piece 12th . The connecting piece and the centering piece 12th are made of a hollow cylindrical locking ring 18th enclosed.

The centering piece 12th , the end piece 10b and the locking ring 18th have corresponding holes 19a , 19b , 19c on.

In these holes 19a , 19b , 19c is a locking element 20th guided.

The locking element 20th is an annular spring 21 assigned to form a further spring storage.

How out 4th it can be seen that there is the pin-shaped locking element 20th from an actuator 22nd in the form of a ball pin, a guide pin 23 , a hollow cylindrical tube 24 and a spring element 25th .

As 4th shows, the spring element is in the assembled state 25th in the pipe 24 that is at the top by the actuator 22nd and on the bottom through the guide pin 23 is secured against loosening.

When the locking element is not locked 20th is the actuating element 22nd without application of force in the bore 19c of the locking ring 18th . The connection element 8th is then inside the centering piece 12th , as in 4th shown.

Will the actuator 22nd actuated, that is, pressed down, the locking element is 20th transferred to the unlocked state. In the unlocked state, the locking head 11 by the spring force of the spring 21 pushed forward so that the connection element is now 8th via the outlet opening 15th to the outside via the locking ring 18th protrudes. The actuator 22nd is then out of the area of the hole 19c out under the centering piece 12th pushed.
