    SUMMARY The invention relates to a rod, intended for use as a training tool wide bar on a surface, comprising an outer tube (1) and an inner tube (2) which are telescopically displaceable in each other, a handle (3) at the top of the outer tube and a wrist bracket (4), a spring-loaded means (12) that allows the inner tube to, under a predetermined resistance to movement, slide inside the outer tube towards a collapsed position when the rod is pushed against the ground. In order to offer movement resistance which allows the user's muscles to work along a significant range of motion, the suspension means comprises an elongate elastic member (12) which is so joined to a respective end of the telescopically meeting parts of the outer tube (1) and the inner tube (29), respectively, that the elastic member is tensioned when the pipe ends of the outer pipe and the inner pipe, respectively, are pushed into each other.

    Thanks to the tensile elasticity of said elastic material, motion resistance with even load over a substantial range of motion of the user's upper body can be easily offered and the complicated mechanical cohesive arrangements with rods described above in combination with compression springs can be avoided, since it the tensile elastic element itself can offer the required clamping force to, like a clamping member, bring together the two telescoping advantages. Furthermore, elastic bands have the advantage that they are inexpensive and can, by simple tensioning devices or simply by pre-tensioning differently, offer different degrees of spring characteristics as desired. As a result, manufacturers of walking sticks do not have to stock compression springs with varying spring characteristics. In addition, elastic bands have acoustic advantages because they are basically silent, and elastomeric material has the advantage of being deformed while exhibiting a linear spring characteristic with some inherent hysteresis or lag, which provides a damping effect which means that the rod's executive resistance is constant and gentle. By replacing pre-existing pressure springs and mechanical cohesive structures with elongated elastic elements, the dead weight of the rod can be substantially reduced while a simple, reliable constructive design of the spring arrangement is obtained.
    From SE 532 108 a rod-like training device of the telescopic type is known which uses the tensile elasticity of an elongate elastic body, such as an elastic band. The rod has an outer tube and an inner tube, the outer tube having a handle with an associated wrist strap.
    The elongate elastic body is connected between the facing ends of the outer tube (handle) and the inner tube, respectively. As a result of the significantly spaced attachment points of the elastic body of the rod, the elastic element extends substantially along the entire length of the rod, which not only means that the elastic element constitutes a bulky and aesthetically pleasing part of the rod as a whole but involves also difficulties in achieving desirable movement resistance between the two telescoping tubes without additional mechanics, which for example include break wheels.
    A first object of the present invention is thus to provide a bar which not only has a shock-absorbing effect, but in a simple, elegant and efficient manner offers the movement resistance which is desirable for achieving a more advanced training movement for the upper body, where the muscles work along a significant range of motion. A second object of the invention is to provide a rod which has a simple, reliable constructive design and which overcomes the disadvantages with which hitherto known devices have been associated.
    These two objects of the invention are achieved by the rod having obtained the features and characteristics set forth in claim 1. The insight underlying the invention is that a combination of continuous movement resistance for effective training and a discrete integration of an elongate elastic element acting between the telescoping outer tube and the inner tube is obtained only by the elongate elastic element being arranged operatively in opposite or adjacent portions of the telescopically guided parts of the outer tube and the inner tube, respectively.
    With a rod such as that defined in the claims, not only is a shock-absorbing effect obtained when the rod is placed against a surface, but a rod is provided which offers the user a continuous resistance to movement over a significant range of motion with the result that the rod can be used as a more effective training tool. what has been possible with hitherto known devices.
    According to a first embodiment of the invention, the elongate elastic element comprises an elastic band of, for example, rubber material which acts between meeting portions of the telescopically active parts of the outer tube and the inner tube, respectively.
    In a second embodiment of the invention, the elongate elastic element consists of a tubular element which acts between the meeting ends of the telescopic tubes via a co-ring projecting from one tube which extends through the tubular element.
    The invention will be described in more detail below with reference to the accompanying drawings, in which; Fig. 1 shows a perspective view of an individual who exercises so-called Fig. 2a-2c show a series of longitudinal sectional views of different parts, in particular adjacent parts of telescopically active parts of a rod in a first embodiment of the invention, Fig. 3 shows a longitudinal sectional view of adjacent parts of telescopically active parts. parts of a rod in a second embodiment of the invention. l fi g. 1 shows a person who during training of the upper body uses a pair of rods according to the present invention, the user performing so-called rod gang. The rods are inclined at an angle backwards and while the user is performing a pendulum movement with the arms, the rod is lowered towards the ground just behind the respective front foot, with the user moving forward. Each rod basically consists of four main parts which comprise an upper outer tube 1, a lower inner tube 2 which is telescopically slidable in a lower end of the outer tube. a rod handle 3 and a wrist bracket 4 in the upper free end of the outer tube 1 and a tip 5 arranged in the lower free end of the inner tube 2. The outer tube 1 of the rod with handle 3 and inner tube 2 with said tip 5 are approximately equal in length.
    I fi g. 2a-2c the constituent parts of the rod are shown in more detail and as can be seen here, the lower end of the outer tube 1 has an end fitting 10 which at the same time forms a guide for telescopic reception of the upper end portion of the inner tube 2 by co-operation with its peripheral outside. 10 15 20 25 30 35 535 914 4 Said end fitting 10 is mounted on the lower end of the outer tube 1 by, for example, gluing. the upper end portion of the inner tube 2 is arranged that when the tip 5 of the rod is applied to a base, from below slide a piece into the lower end portion of the outer tube 1 for co-operation with an elongate elastic element generally designated by 12. Said elongate elastic elements 12 are discreetly housed and operatively between the opposite end portions of the two telescopic tubes 1, 2 to form a resistance to movement between said telescopic parts when the tip 5 of the rod is pushed down against a ground. The outer diameter of the inner tube 2 is so adapted to the inner diameter of the outer tube 1 that the upper end portion of the inner tube can be slid into the lower end portion of the outer tube 1. A movement restricting member 14 allows the two facing pipe ends to telescopically slide into each other while preventing the upper end of the inner tube 2 from sliding uncontrollably out of the lower end portion of the outer tube 1 and thus out of the telescopic action therewith. This movement-limiting member 14 comprises a stop screw 15 arranged in the end fitting 10. Via a bore 16 directed radially towards the center of the rod, the stop screw 15 extends with its front tip 17 a distance into an annular gap 18 delimited between the outer tube 1 and the inner tube 2. The front tip 17 thus settles inside said gap 18 and as a result the inner tube 2 is prevented from sliding out of the outer tube 1 by co-operation between the tip 17 of the stop screw 15 and a piston 19 arranged on the upper end of the inner tube 2.
    In order for the pole to be used as an effective training tool, it is important that the length of the pole can be adapted to the user's body length. The recommended length for this type of rod is usually about 70-80% of the body length. The rod length is adjustable and for this purpose the lower inner tube 2 consists of two pipe sections 2a, 2b (one upper and one lower) which are telescopically slidable into each other (see Fig. 2c).
    As further shown by fi g. 2c, a telescopic lock 20 is mounted in the upper end of the lower 2b of said telescopic pipe sections 2a, 2b. This type of telescopic lock 20 consists of a telescopic sleeve 21 which is arranged to be able to be stretched out by means of a wedge (not shown but located below the telescopic sleeve) which can be turned in and out of the telescopic sleeve 21 by means of a threaded shaft 22, which is attached to the upper end of the lower pipe piece 2b. An end fitting 23, similar to that described above, prevents the lower pipe piece 2b from sliding uncontrollably out of the lower end of the upper pipe piece 2a.
    With reference to Fig. 2b and as mentioned here initially, it is essential that the elongate elastic element 12 can be accommodated and integrated in a discrete manner between the telescoping outer and inner tubes 1 and 2, respectively. 2 opposite or interposed ends without limiting the ability to accommodate significant telescopic movements between the two cooperating tube ends. The elongate elastic element 12 here comprises an elastic band of rubber material which is tensioned (energy accumulates) and forms a resistance to movement when the telescopically interposed tube ends of the outer tube 1 and the inner tube 2, respectively, are pushed into each other, such as illustrated by the opposite arrows AA in Fig. 2b. As mentioned above, an annular space 18 is defined between the facing and telescopically active end portions of the outer tube 1 and the inner tube 2, respectively. telescopically meeting pipe parts 1, 2. A first fastening member 25a for one end 12a of the elastic element 12 is arranged in the end fitting 10 which is externally mounted on the lower end of the outer pipe 1. The end fitting 10 has a channel 26 which leads into a space 27 in the end fitting in which said first fastening means 25a is arranged.
    A corresponding fastening member 25b for the other end 12b of the elastic element 12 is arranged in the diametrically opposite side of the end fitting 10.
    The elongate elastic element 12 is pulled with a part 12c over an upper end portion of the inner tube 2, which in order to achieve telescopic action is accommodated in the lower end portion of the outer tube 1. The two fastening means 12a, 12b each comprise a combination of a tongue 28 arranged in the space 27 of the end fitting 10 and a detachable shackle 29 which can be lowered over the tongue so that in the clamp it engages with one end 12a of the elastic element 12 which has been pulled over the tongue. The elongate elastic member 12 extends in a controlled manner with said portion 12c over the upper end of the inner tube 2 in a fastener 25c which is formed as a channel arranged below the piston 19. To offer soft and quiet running the piston 19 may comprise a relatively soft material with low friction, for example felt material. The piston 19 is axed in the upper end of the inner tube 2 via a piece of rubber 31 contained therein.
    A threaded pipe insert 32 of metal and a screw 33 cooperating with it are integrated in the rubber piece 31. The piston 19 forms a guide for the front end of the inner pipe 2. In the exemplary embodiment shown, the elongate elastic element 12 is of the band-shaped type and with said part 12c running over the upper end of the inner tube 2 and further down on the diametrically opposite side of the telescoping upper end portion of the inner tube 2. It should be understood that depending on the desired resistance to movement, the rod could be equipped with any number of elastic elements 12. Fig. 3 shows an alternative embodiment of the invention in which the elongate elastic band-shaped element described above has been replaced by an elastic tubular element. element 40, which via a first and second fastening means 41, 42 is so fastened in the opposite ends of the telescopic tubes 1, 2 that the elastic tubular element 40 offers a resistance to movement for the user when the tip 5 of the rod is pushed down against a base. A first piston 45, which may comprise ll material, is attached to the free end of an elongate carrier 46 shaped like a rod, the other end of which is connected a bit into the outer tube 1 via a fastening means 48 axed by screws 47 so that the carrier 46, sliding extending from the lower end of the outer tube 1, extends coaxially with the two telescopic tubes 1, 2 of the rod. in its center has an axial bore 49 through which the carrier 46 runs when the two advantages 1,2 telescopes. The second piston 48 supported by the inner tube 2 is intended to slide inside the lower end of the outer tube 1, while the first piston 45 supported by the carrier 46 is intended to slide inside the upper end of the inner tube 2. The elastic tubular member 40 is attached to the ends 12a, 12b of said first and second pistons 45, 48, respectively, in such a way that the tubular member extends coaxially between the two telescopically spaced tube ends 1, 2 and offers a movement resistance for the user. when the tip 5 of the rod is pushed down against a surface. A piece of the carrier 46 thus extends along the central center of the elastic tubular member 12.
    As shown by a closer study of fi g. 3, an annular gap-like space 49 is delimited between the carrier 46 of the outer tube 1 and the inside of the inner tube 2. In this annular space 49, the elastic tubular element 12 can move (tension and unload) between the opposite ends of the telescopic tubes 1, 2 and thus offer resistance to movement when the telescopic tubes 1, 2 are pushed together, such as when the tip 5 of the rod is applied to a base . That is, when the inner tube 2, as a result of a shock against the substrate, pushes a piece into the lower end portion of the outer tube 1 from below. The latter relationship, when the telescopically intertwined tube ends of the outer tube 1 and the inner tube 2, respectively, are pushed into each other and the elastic tubular element 12 is stretched or stretched, is illustrated by the opposite arrows A-A in fig. 3.
    The invention is not limited to what is described above and that shown in the drawings, but can be changed and modified in a number of different ways within the scope of the concept of invention set forth in the appended claims.
