This application claims benefit of European Application No. 20204840.1, filed 30 Oct. 2020, and which application is incorporated herein by reference. To the extent appropriate, a claim of priority is made to the above-disclosed application.
A workout equipment comprising a frame, a movable arm pivotally connected to the frame, the movable arm having a first end and a second end, at least one movable load unit supported by said movable arm and load transfer means configured to move said load unit along said movable arm.
Workout equipment comprising movable weight units, such as weight plates, are commonly used in weight exercising and training both in indoor and outdoor training facilities. In indoor training load adjustment of the workout equipment is typically achieved by loose, removable weight units. Problems relating to storing of loose weight units, maintenance issues and safety regulations, however, restrict the use of loose weight units in outdoor training equipment. Instead, in outdoor workout devices the load of the workout device is usually based on the body weight of the trainer, weight of the moving parts of the equipment and/or selection of the gripping position of the torque arm of the equipment. Load adjustment in the outdoor workout equipment is therefore usually inaccurate and complicated.
Document EP 3344348 B1 discloses an arrangement and a method for adjusting load in a training equipment especially suitable for outdoor use. The equipment comprises a moving arm pivotally connected to a frame, at least one load unit and an elongated guideway connected to the moving arm along which guideway the load unit is arranged to move. The arrangement further comprises a locking device for securing the load unit immovably to the guideway to a number of pre-determined locking positions. In EP 3344348 B1 accurate and stepless adjustment of the position of the weight unit is not possible.
Document EP 3434338 A1 discloses a sports training device for creating adjustable load. The device comprises a moving arm pivotally connected to a swinging axis and an U-shaped guide along which weight units can be moved. The weigh units are stacked on to the moving arm to two different distances from the swinging axis. Also in EP 3434338 A1 an accurate and stepless adjustment of the position of the weight units is not possible.
Document EP 1423170 B1 discloses a weight training apparatus with a load arm pivotably mounted on a frame, on which load arm a weight is mounted. The position of the weight is adjustable in the longitudinal direction of the load arm. The weight is located asymmetrically on the side of the load arm causing torsional stress to the load arm and to the weight transfer means.

The front part of the movable arm is supported by a lower stud 17. The lower stud is located below the movable arm and the casing 28 in a slanted position the upper end of the stud abutting the movable arm and the lower end of the stud abutting the base on which the workout equipment stands. In the upper end of the lower stud there is a support plate against which the front part of the movable arm is arranged to settle. The opposite edges of the support plate are provided with holder plates 35. The lower stud is connected to the lower beam with a joint beam 19 and the corner joint of the joint beam and the lower stud is reinforced with a slanting support bracket 21 connecting the lower beam and the joint beam. The lower stud 17, joint beam 19 and the support bracket 21 are parts of the frame 10.
In the front end of the casing 28 these are two handles 26 for the use of the workout equipment. The handles are attached from their first ends to the moving arm inside the casing and the second ends of the handles are provided with hand grips. The handles are removably connected to the moving arm, which makes possible to furnish the workout equipment with different kind of interchangeable handles. The handles shown in

A first rear shaft pin 14a is attached to the first guide 20a and a second rear shaft pin 14b is attached to the second guide 20b. The first and second rear shaft pins are aligned and they lie in the same fictional plane with the first and second guides. The rear shaft pins do not extend into the gap between the first and second guides. The first and second rear shaft pins together constitute the rear swing axle 14 locating closer to the second end of the movable arm 12 than to the first end of the movable arm.
In a similar manner a first front shaft pin 36a is attached to the first guide 20a and a second front shaft pin 36b is attached to the second guide 20b. The first and second front shaft pins are aligned and they lie in the same fictional plane with the first and second guides. The front shaft pins do not extend into the gap between the first and second guides. The first and second front shaft pins together constitute the front swing axle 36, which locates closer to the first end of the movable arm 12 than to the second end of the movable arm.
The rear swing axle and the front swing axle provide two alternative fixing elements, with which the movable arm can be connected to the frame. The free ends of the shaft pins extend outside the casing and the ends of the pins are rotatably attached to the support posts of the frame with the aid of a fixing bracket 42. The fixing bracket has a tubular receiving portion into which the free end of the pin is inserted and a mounting plate, which can be attached to fixing holes of the support posts with bolts and nuts. The operation of the workout equipment depends on which axle is connected to the frame. In
Further, a handle carrier 48 is attached to first guide 20a and to the second guide 20b near the first ends of the guides. The free ends of the handle carriers protruding outside the casing 28 are provided with fastening flanges, to which handles (not shown) are secured.
Inside the casing there is a load unit 16 comprising a row of the weight plates 44, which are connected together to a single unit with connecting bars 46. The number of the weight plates can be chosen in the assembly phase of the equipment. The weight plates have a triangle resembling shape having straight sides connected by rounded corners. On the opposing sides of the weight plates there are slots 47, which form a three-sided channel on the opposing sides of the load unit extending through the whole load unit. The first guide 20a is placed into the first channel and the second guide 20b is placed into the second channel. The outer dimensions of the first and second guides are slightly smaller than the dimensions of the channel leaving a play, i.e. a narrow gap, between the surface of the guides and the surface of the channel. In both ends of the channel there is a slide bearing 43, which enables sliding of the load unit along the guides with minimum friction.
The rear and front shafts pins 14a, 14b, 36a, 36b are attached to those sides on the guides which are facing the open side of the channels. Further, the shaft pins do not protrude into the gap between the guides. Therefore, the rear and front shafts pins do not hinder the movement of the load unit along the first and second guides.
In the middle of each weight plate there is a hole creating an aperture 27 through the whole load unit 16, through which aperture the threaded rod 22 protrudes. In the opposing ends of the aperture there are sleeves 23 fixedly connected to the load unit. The inner surfaces of the sleeves have inner threads matching the threads of the threaded bar. Twisting the rotator 24, i.e. the wheel, in the first end of the threaded rod forces the load unit to slide along the first and second guides. Depending on the rotation direction of the threaded rod, the load unit moves either towards the first end of the movable arm or towards the second end of the movable arm.
