INVENTOR HIS ATTORNEYS My ta June 29, 1937. A. KRAUS EXERCISING DEVICE Filed July 12, 1935 Animal F1229 Patented lune 29, 1937 TA'E'ES 2 Glaims.

My invention relates to exercising devices, and has among its objects and advantages the provision of an improved punching bag.

An object of my invention is to provide a punching bag characterized by a quick recovery after being struck and in which the bag is shaped to simulate the head and body of a boxer. The bag also embodiesa novel jointed structure operating to minimize the force of the recoil and in which the head part of the bag is jointedly connected with the body.

In the accompanying drawing: Fig. 1 is a plan view of the device; Fig. 2 is a sectional View along the line 22 of Fig. 1; and

Fig. 3 is a sectional view along the line 33 of Fig. 2.

In the embodiment selected to illustrate my invention, the figure Ill, including a head part I2 and a body part it, is mounted upon a standard I 6 mounted upon a spring structure I8 fixedly connected with a plate 20 anchored to the floor 22. The spring l8 yields when the bag is struck to permit oscillation of the bag, and operates to impart a quick return movement to the bag.

The body I4 comprises a covering 24 filled with padding 26 such as curled hair or other suitable fibrous material. The covering 24 extends around the head l2 and has its bottom end sewed at 28 to a bottom part 30 having an opening for the reception of the shaft 32. The

latter is provided with a flange 34 against which the part 30 bears. I place a plate 36 against the outer face of the part 36 and securely fasten the latter between the flanges 34 and 35 by screws 38.

To the upper end of the shaft 32 I connect a joint til which in turn is connected with a shaft $2 extending vertically through the head 52. The joint do is of a bendable nature to permit bending of the punching bag at a point slightly below the neck 45. When the device is struck above the joint M3, the head portion is thrown back. In cases where the bag is struck below or in the locality of the joint $0, the force imparts a bending action to the device. In addition to providing a jointed figure simulating the body of a boxer, the joint performs an important function in breaking the force of the recoiling bag. When the back is struck during a rapid recovery movement, the bending action bends to break the force of the impact which might otherwise injure the user.

Specifically the joint 40 comprises a flanged member 46 having threaded relation with the threaded end 48 of the shaft 32. Similarly, the threaded end 5i! of the shaft 62 is provided with a flanged member 52. Upon the neck parts 54 of the two members 35 and 52, I mount a coil spring 56. This spring is close Wound, preferably with initial tension, and has threaded relation with the necks 56 of the members 46 and 52. Upon the spring I mount a rubber casing 58 to prevent the material of the bag from working between the convolutions of the spring.

Within the cover 28 encircling the head l2, I mount an inner covering 58. The lower end of this covering is wrapped firmly about the shaft 42 as at 62 adjacent the flange G l upon the shaft. The upper end of the shaft 42 is provided with a flange 66 against which the covering lies. I position a disc 58 in vertical alignment with the flange 66 and pinch the coverings 2L and 50 securely therebetween by means of screws Iii.

One end of the spring 12 of the structure l8 has threaded relation with a post M having a neck 16 at its lower end. This neck passes through an opening in the plate 28 and is firmly secured thereby by riveting the end of the neck. The upper end of the spring 12 has threaded relation with a sleeve I8 slidably mounted upon the shaft 32.

I mount a cone shaped tube 86 upon a flange 84 through the medium of screws 88. This flange has its upper end terminating in close relation with the bottom of the body E5. The tube 86 enhances the ornamental appearance of the bag.

Within the spring '52 I mount a second spring 90 of the same type as the spring 55. One end of the spring 90 has threaded relation with a post 92 positioned within the bore 94 in the post M. The post 92 passes through an opening 96 in the post 14 and is made secure by riveting its end at 98.

The lower end of the shaft 32 has a threaded reach I on upon which I mount a flanged member I02 for connection with the spring 3 9. The member I02 has threaded relation with the spring 98. Normally the spring structure i8 supports the bag in the vertical position of Fig. 1. The spring structure imparts a rapid rebound of the figure so as to position the figure in a vertical position by the time that the user is ready for another blow.

In providing a padded figure, I eliminate the necessity for inflating equipment. The bag structure is of durable construction in that I eliminate deflation of the bag in the event of damage to the covering. In addition, the bag is padded to a degree of firmness simulating the body of an adversary.

Without further elaboration, the foregoing will so fully explain my invention that others may, by applying current knowledge, readily adapt the same for use under various conditions of service.

I claim:

1. An exercising device comprising a striking bag including a lower part and an upper part, shafts extending through portions of said parts and being arranged in spaced, axial alignment, said shafts being anchored to said parts, said parts being padded with a resilient material, a resilient universal connection between said shaft parts and housed Within the striking bag, said resilient universal connection operating to urge the shaft parts to their axial aligned positions, a base, and resilient means connecting the base with one of said shafts for urging the bag toward a vertical position and eifecting a quick recovery of the bag.

2. Anexercising device comprising a striking bag including a lower part and an upper part, said bag being padded With a resilient material, shafts positioned within both parts and normally arranged in axial alignment, a convoluted spring having its ends connected with said shafts, said spring urging the shafts to their normal position, a tube of resilient material enclosing the convoluted spring, to prevent padding from working between the convolutions of the spring, one of said shafts extending to a position exteriorly of the striking bag, a base, and a resilient connection between the base and the shaft part extending exteriorly of the bag.
