Abstract

An adjustable barbell or dumbbell or exercise device includes a handle (10) having two ends (12), two carriers (20) each having a tube (21) attached to the end (12) of the handle (10), and a number of weights (40) each having an opening (41) for receiving the tube (21), and a vibrating device (50) disposed in the handle (10) for generating a vibration to the handle (10), the vibrating device (50) includes a motor (51) engaged into the handle (10), or in a receptacle (52), and a power source (53) for energizing the motor (51), and a button (55) for actuating the motor (51), two latches (30) are engaged with the handle (10) for anchoring the weights (40) on the carrier (20) and the handle (10).

Description

The invention relates to the filed of adjustable barbells or dumbbells or exercise devices. More specifically, the invention relates to an adjustable exercise device according to the preamble portion of claim 1.
Typical dumbbells comprise a handle to be grasped by the user and a number of weight plates to be attached onto the handle for weight lifting or exercising purposes.
The invention aims at improving the exercising functions of adjustable exercise devices.
This technical problem is solved by an adjustable exercise device as defined in claim 1. Advantageous embodiments are indicated in further claims.
The invention provides an adjustable barbell or dumbbell or exercise device including a vibrating device for generating a vibration to the weight carrier or handle or to the hands of the user, which, up to now was not known for typical dumbbells or exercise devices. In the drawings

FIG. 1: is a partial exploded view of an adjustable dumbbell;
FIGS. 2, 7: are perspective views of the adjustable dumbbell;
FIGS. 3, 4, 5, 6: are partial perspective views of the dumbbell;
FIGS. 8, 9: are partial exploded views of the dumbbell; and
FIG. 10: is a perspective view illustrating the other arrangement of the adjustable dumbbell.

DESCRIPTION OF THE PREFERRED EMBODIMENT

FIGS. 1 to 4 show an adjustable exercise device, by example, in the form of a dumbbell. The adjustable exercise device can also be e.g. a barbell.
The dumbbell or adjustable exercise device 1 comprises a handle 10 including a hand grip 11 having two ends 12 and a compartment 14. Two carriers 20 each include a tube 21 attached to the ends 12 of the handle 10 with a pin 15, an inner anchor plate 22 having an outer diameter greater than that of the tube 21, and one or more (such as three) notches or cut-off portions 23 for forming a non-circular or triangular cross section. The carriers 20 each include a chamber 24 (FIG. 1), and one or more slots 25 located in the cut-off portion 23 and communicative with the chamber 24, the pins 15 are engaged with the anchor plate 22 (FIGS. 3, 6) for securing the tubes 21 of the carriers 20 to the handle 10.
A latch 30 includes a shank 31 engaged into the tube 21 and having a bore 32 (FIGS. 1, 4-5) for receiving the handle 10, and one or more (such as two opposite) grooves 33 for engaging with the pin 15 and for limiting the latch 30 to rotate relative to the carrier 20 and the handle 10. The latch 30 includes a knob 34 at one end or outer end of the shank 31 and having an outer diameter greater than that of the shank 31, and having an outer contour similar to that of the tube 21 of the carrier 20 (FIGS. 2-3, 8), and the latch 30 is rotatable relative to the carrier 20 and the handle 10 to an interlock or crisscross position (FIGS. 6-7, and 9).
The latch 30 includes one or more (such as three) rows of tongues 35 aligned with the slots 25 of the carrier 20 for selectively extending out through the slots 25 of the carrier 20 (FIGS. 6, 9), or engaged in the tube 21 of the carrier 20 (FIGS. 3, 8). A number of weights 40 each include an opening 41 formed in the central and having a non-circular or triangular cross section similar to that of the tube 21 for engaging with the tube 21 and for preventing the weight 40 from being rotated relative to the carrier 20 and the handle 10.
In operation, the required weights 40 (FIGS. 3, 8) may be engaged onto or disengaged from the carrier 20 when the knob 34 of the latch 30 is aligned with the tube 21 of the carrier 20 and when the tongues 35 of the latch 30 are engaged in the tube 21. After the required weights 40 are engaged onto the carrier 20, the knob 34 of the latch 30 may be rotated relative to the carrier 20 and the handle 10 to the interlock position (FIGS. 6-7, 9), and the tongues 35 of the latch 30 are extended out through the slots 25 of the carrier 20 and engaged with the weights 40 for locking the weights 40 to the carrier 20 and the handle 10. As shown in FIG. 10, the length or dimension of the handle 101 and/or the weights 40 may be enlarged to form and to act as a barbell.
A vibrating device 50 includes a motor 51 engaged in a receptacle 52 or directly engaged into the compartment 14 of the handle 10, and one or more power sources or batteries 53 engaged in the receptacle 52 or directly engaged into the handle 10, and a button 55 engaged in the shank 31 and extended out of the knob 34 for actuating the motor 51 to generate a vibration to the weight carrier or handle 10 or the adjustable dumbbell 1 or the user.
