DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a barbell bar for attaching weights called bells to both ends for weight training and weight gain.

[0002]

2. Description of the Related Art In a conventional barbell, as shown in FIG. 5 (a), a disk-shaped heavy object (usually called a bell) B is attached to and detached from both ends of a linear bar A in the axial direction. The total weight can be adjusted by changing the number and weight of the bells B attached to the bar A. Bar A
Is formed with a knurled grip portion C, and a bell B is a mounting hole into which a bell mounting portion D at both ends of a bar A can be inserted at the center of a metal disk as shown in FIG. E is open. To attach the bell B to the bar A shown in FIG. 4A, a ring-shaped inner collar F is attached inside the bell attachment portions D at both ends of the bar A as shown in FIG. Is inserted into the mounting hole E of the bell B, and the ring-shaped outer collar G is put on the bell mounting portions D at both ends protruding outward from the bell B. To fix the bell B in between.

Although the inside diameter of the mounting hole E of the bell B is standardized, there are also two types in the standard, and the bell mounting portion D has a diameter of 28 mm and a diameter of 50 mm. In this case, if two dimensions are prepared for the bell mounting portion D of the bar A and the mounting hole E of the bell B for 25 mm and 50 mm, the bell mounting portion D can be used properly depending on the application. There is a waste that two types of bars A and B having different dimensions of D and mounting hole E must be prepared. Therefore, conventionally, the diameter of the bell mounting portion D is 28 mm.
And a bell B having a mounting hole E of 28 mm and a bell B of 50 mm are prepared.
A bell B having a mounting hole E of 28 mm is mounted on a bell mounting portion D having a diameter of m or an outer diameter of 5 mm on a bell mounting portion D having a diameter of 28 mm.
A cylindrical sleeve H of 0 mm is covered, and a mounting hole E is covered with a bell B of 50 mm on the outer side thereof so that it can be mounted and fixed.

[0006] In training using a conventional barbell, as shown in FIG. 6 (a), while holding a grip portion C of a bar A to which a desired number of bells B are attached, as shown in FIG. When the user stands up and stands up, the squatting motion is repeated (squatting) as shown in FIG. 7 (a), thereby training the leg and hip by raising and lowering the barbell, and standing up as shown in FIG. 7 (a, b). There is training to raise and lower the barbell in front of the body in order to strengthen the arms.

However, since the conventional bar A is linear, when performing training as shown in FIGS. 6 and 7, the bar A is moved to the body as shown in FIGS. 6 (c) and 7 (c). The barbell's center of gravity is biased toward the front of the body. For this reason, if squats are performed or the barbell is raised or lowered in this state, an excessive load may be applied to the waist and the back muscles, which may cause injury.

In order to solve the above problem, a bar A for a barbell as shown in FIG. 8 has been developed. This bar A is generally called a trap bar,
As shown in the figure, a diamond-shaped set portion I of a size that allows a human to enter is formed between the bell attachment portions D at both ends, and grip portions C are provided on the left and right inner sides of the set portion I. is there. When this bar A is used, the bell mounting portion D
After the inner collar F, the bell B, and the outer collar G are mounted in this order, a person enters the inside of the set part I, grasps the grip part C, and performs training such as raising and lowering the squat and the barbell.

[0007]

FIG. 8 shows that the bar A has a symmetrical shape in the front-rear and left-right directions, and the bell B is located right beside the body in the set portion I. Although the barbell does not have a deviated center of gravity, the above-described problems of the barbell can be solved. However, there are the following problems. (1) In order for a human to enter the inside of the set portion I, the person must straddle the frame J on the outer periphery of the set portion I or lift the bar A to pass under the frame J. It is troublesome to go in and out from inside. (2) When the bell B is attached to the bell attaching portion D, the set portion I is higher than the floor by the radius of the bell B, so that the frame J
When straddling, there is a risk of falling over the frame J.

[0008]

(Embodiment 1) A first embodiment of a barbell bar according to the present invention will be described in detail with reference to FIG. This barbell bar is shown in FIG.
As shown in b), the center portion of the metal bar 1 in the longitudinal direction is curved in a semicircular arc to form a set portion 3 having a size that allows a human to enter inside, and the set portion 3 is formed. A doorway 4 is formed on the side opposite to the direction of curvature of the vehicle so that a person can enter and exit the set section 3 from the doorway 4.

A grip 10 is formed on both sides of the set portion 3 by knurling the surface, and the tip is curved in the opposite direction to form a small arc-shaped balance portion 11 having a smaller diameter than the set portion 3. Further, both sides of the balance portion 11 are formed linearly, and the bell attachment portions 2 are formed at both ends.
A reinforcing member 12 made of a metal round bar is attached to the base of the balance portion 11 to reinforce the set portion 3 and the balance portion 11. The tip side of the bell mounting portion 2 is made gradually thinner toward the outside so that it can be easily inserted into the mounting hole E of the bell B. Also,
A screw hole 13 is opened on the bell mounting portion 2,
The sleeve 14 can be fixed by screwing a screw through a screw hole of the sleeve 14 placed on the outside thereof. FIG.
Although a screw hole is also opened in the lower surface of the bell mounting portion 2, it is not shown because it is just below the screw hole 13 opened in the upper surface. Rubber grip may be attached to the grip 10 or irregularities may be formed on the outer peripheral surface in accordance with the shape of the palm to provide an anti-slip function.

[0013] As shown in FIG.
The reinforcing member 1 and the reinforcing member 12 are formed on the opposite side of the set portion 3 with respect to a center axis XX connecting between the bell mounting portions 2 at both ends. In this case, the weight of the set portion 3 and the weight obtained by adding the balance portion 11 and the reinforcing member 12 have the same weight with respect to the central axis XX, and the weight before and after the central axis XX Are balanced. The bar 1 and the reinforcing member 12 are metal bars of the same material and the same outer diameter, and their surfaces are chrome-plated for enhancing the texture and preventing rust.

The weight of the setting section 3 and the balance section 11
And the reinforcing material 12 are added to the bell mounting portions 2 at both ends.
If the balance is not good before and after the central axis XX connecting the parts, a weight 15 is attached to an arbitrary portion to balance the weight. Specifically, for example, two stainless steel or iron semi-disk-shaped weights 15 having a bolt hole 16 at the center as shown in FIG. 4A are prepared, and as shown in FIG. As shown in FIG. 4, the weight 15 is attached to the balance portion 11 by sandwiching the balance portion 11 from above and below.
As shown in (a), a bolt 18 is screwed through a bolt hole 16 of one weight 15 via a washer 17 to connect and fix the upper and lower weights 15. Of course, the shape, material,
The mounting position, the mounting method, etc. are not limited to those shown in FIG.

The metal used as the material of the bar 1 is iron, aluminum,
Desired ones such as titanium, stainless steel and other alloys can be selected and used. A material other than chrome can also be used for plating applied to the bar 1.

In the embodiment shown in FIG. 1, the outer diameter of the bar 1 is 28 m.
m, the length of the bell mounting part 2 is 270 mm, the radius of the set part 3 is 315 mm, the radius of the balance part 11 is 70 mm,
The length of the grip 10 was 200 mm, and the length from the tip of one bell attachment part 2 to the tip of the other bell attachment part 2 was 1520 mm. It goes without saying that the dimensions can be set other than these.

(Example of Use) A bell B having a desired weight is mounted on the bell mounting portions 2 at both ends.
In this case, after mounting the inner collar 19 on the outer periphery of the bell mounting portion 2 or mounting the inner collar 19 on the outer circumference of the sleeve 14 over the bell mounting portion 2 as shown in FIG. The bell B is mounted, and the outer collar 20 is put on the outside of the bell B, and the bell B is mounted and fixed. Thereafter, the user puts his / her body into the inside of the set unit 3 through the entrance 4 and grasps the grip 10, and FIG.
Raise and lower the barbell as shown in FIG. In this case, since the bar center of gravity is located near the center of the body, no excessive load is applied to the waist and back muscles.

An example of a training menu for a beginner when using the barbell bar 30 of the present invention is shown below. (1) Perform sufficient preparation exercises such as stretching exercises to soften various joints. (2) After completing the preparatory exercise, perform Hindu Squat (Hindu Squat). With Hindu squats, put your hands behind your head, stick your chin forward, stretch out your chest, stand up as if you were pushing your hips backwards, breathe in when you stand up, squat slowly, squat for a moment Stop the movement and (if the heel floats off the floor when squatting, lay a plate about 2 cm thick under the heel.) Then continue a series of actions such as slowly rising while exhaling This is a repetitive exercise. This Hindu squat is repeated 1 to 2 sets, with 10 to 15 times as one set. When doing Hindu squats, always try to keep your back upright so that your back is not rounded. (3) Next, the same operation as the Hindu squat is repeated 10 times while holding only the bar 30 with both hands without attaching the bell B to the bar 30 of the present invention. When holding the bar 30, FIG.
As shown in (1), the body is put into the inside of the set part 3 from the entrance 4 and the grips 10 on both sides of the set part 3 are gripped beside the body. (4) A lighter bell B is attached to the bell attaching portion 2 of the bar 30 to perform the same operation as the Hindu squat. This is performed two to three times, with 10 times as one set. The break between each set is 1-2 minutes. However, when the weight of the bar 30 alone is sufficient, the operation is performed without attaching the bell B. This completes the training on the first day. The next day and the next two days do not train for 2 days due to muscle pain. (5) After the fourth day, the training of the above (1) to (4) is repeated. Specifically, a person aiming at shape-up, after the above-mentioned preparation exercise (1), performs the ordinary Hindu squat of (2) 10 to 15 times, and the Hindu squat of only (3) the barbell bar 30. 10-15 times,
Hindu squat with bell B in (4)
One set is performed 15 times, and three sets are performed. The break between each set is 1-2 minutes and is repeated every 1-2 days. If the purpose is to increase the power (bulk), the number of each Hindu squat is set to 10 to 15 times, one set, and three sets. The break between each set is 2-3 minutes and is repeated every 2-3 days. In both cases, when the above training becomes easier, the number of times and the weight of the bell are gradually increased, and the number of sets is increased to 4 sets continuously for 2 months and thereafter.

The above example of use is merely an example, and the barbell bar of the present invention can be used for shoulder shrugs and two-hands presses.

(Other Embodiments) The shape of the set portion 3 can be a square, polygon, ellipse or any other desired shape other than the arc shape.

The surface of the bar 1 may be coated with a rust preventive or a paint without plating. The cross-sectional shape of the bar 1 may be a polygon other than a circle, such as a square, hexagon, or octagon. If the bar 1 is polygonal,
The grip 10 also has a polygonal shape, and can provide a non-slip effect.

[0022]

According to the first invention of the present application, a bar mounting portion is formed at both ends of a bar, and a set portion which is recessed so that a person can enter is formed between both bell mounting portions.
Since the entrance through which the person can enter and exit the set portion is opened, the following effects are obtained. (1) When the bell is attached to the bell attaching portion and the user enters the inside of the set portion and grasps the set portion, the bell is positioned right beside the body, so that the barb center of gravity does not deviate in front of the body.
Therefore, there is no fear of injuries due to excessive load on the waist and back muscles during training. (2) When entering or exiting the inside of the set section, there is no fear of falling over the set section.

According to the second invention of the present application, the weights before and after the center axis of the bell mounting portion at both ends of the bar are balanced.
The following effects are obtained in addition to the above effects. (1) The barbell's center of gravity is not biased toward the front or back of the body. Therefore, it is possible to efficiently perform training without exerting force on unnecessary parts of the body during training.
