Description

Treadmill handrail

The invention relates to a sports equipment, in particular to a handrail of a treadmill.

An existing treadmill (Taiwan Certificate No. M375527 patent case) has a pole extending upward from both sides of a frame, and a U-shaped armrest is installed on the top of the poles, and a control is installed on the armrest The panel is composed of the poles and the U-shaped handrail to form a handrail frame group. And the joints of the uprights and the armrest are locked by screws.

In this treadmill, since the control panel is installed on the armrest, the front side of the armrest will have a downward rotation tendency due to the weight of the control panel, and the poles are connected to the armrest. The screws at the place will also withstand large shear forces. When used for a period of time, it may cause the armrest to shake and the structural strength is not good. Therefore, the structural strength of the armrest frame group of this treadmill still needs to be strengthened.

Therefore, an object of the present invention is to provide a treadmill handrail that can strengthen the structural strength.

Therefore, the treadmill handrail of the present invention includes a handrail frame, a pair of connection units, and at least two locking members. The armrest frame is U-shaped and includes two side frame members that are opposite and spaced along a horizontal axis, and a cross frame member connected between the side frame members, and the side frame members intersect each other along one Extending along the axis of the transverse axis, each side frame member has a joint portion. Each of the connection units includes a socket member connected to the side frame members with an inner jacket and an extension member connected to the socket member, and each set of connector members is concave and convex complementary to the corresponding joint portion and A fitting portion which is non-rotatably sleeved with each other. The locking members are respectively locked to the fitting portion of the connection unit of the armrest frame.

The function of the invention lies in: using the sockets of the connection units and the side frame members to be inner and outer sleeves, the joint portions and the corresponding mating portions to be concave and convex complementary and non-rotatably socketed to each other, and to use The fasteners respectively lock the coupling portions to the fitting portions, so that the armrest frame can be firmly combined with the connection units, and the overall structural strength is good after the combination.

Other features and effects of the present invention will be clearly presented in the embodiment with reference to the drawings, in which: FIG. 1 is a perspective view of an embodiment of a treadmill handrail of the present invention; FIG. 2 is a perspective view of the embodiment Exploded view; and FIG. 3 is a sectional view taken along line III-III in FIG. 1. FIG.

Referring to FIG. 1, FIG. 2, and FIG. 3, an embodiment of the treadmill handrail of the present invention includes an armrest frame 10, a pair of connection units 20, and a plurality of locking members 30. In order to make the drawing simple, only one connection unit 20 is shown in FIG. 2 and FIG. 3, and only one connection unit 20 is described below.

The armrest frame 10 is U-shaped, and includes two side frame members 11 arranged opposite to each other along a horizontal axis X (with the connection unit 20, only one side frame member 11 will be described below), and one connected to The lateral frame members 12 between the side frame members 11 extend along an axis L that intersects the horizontal axis X perpendicularly. The side frame members 11 are hollow and tubular, and also have an inner side wall 111, An outer side wall 112 spaced from the inner side wall 111 along the horizontal axis X, and a pair of end walls 113 connected between the inner side wall 111 and the outer side wall 112. The inner side wall 111, the outer side wall 112, and The end walls 113 collectively define a space 114, the inner side wall 111 has a first wall surface 115, a second wall surface 116 opposite to the first wall surface 115 and adjacent to the space 114, and most of the The wall surface 116 protrudes toward the space 114 and has a hollow cone-shaped convex seat 117. Each convex seat 117 defines a recessed hole 118 whose opening corresponds to the first wall surface 115. Each convex seat 117 has a communication hole connected to the recess. The locking hole 119 of the hole 118, and the concave holes 118 collectively define a joint portion 13, and the outer side wall 112 has a plurality of corresponding ones. Perforations 119 'in the keyholes 119.

The connecting unit 20 includes a socket member 21 connected to the side frame member 11 with an inner jacket and an extension member 22 connected to the socket member 21. The socket member 21 has a corresponding joint portion 13. A fitting portion 23 which is complementary to each other and is non-rotatably sleeved with each other. The socket 21 has a positioning wall 211 abutting against the inner side wall 111, two limiting walls 212 connected to the positioning wall 211 and sleeved on the outer sides of the end walls 113, and a connecting wall. A retaining wall 213 between the 211 and the limiting walls 212. The positioning wall 211 and the limiting walls 212 together define a groove 24 that is open laterally. The sockets 214 which are equal to the convex seat 117 and can be nested in the recessed holes 118 are shaped like a conical block and are protruded in the groove 24. The sockets 214 collectively define the The fitting portions 23 and the holders 214 each have a screw hole 215 corresponding to the lock holes 119.

The lock members 30 are respectively connected to the joint portion 13 of the connection unit 20 with the joint portion 13 of the armrest frame 10. The locking members 30 are screws, each having a screw head 31 that abuts against the protrusions 117, and a screw portion 32 that passes through the perforations 119 and is screwed into the screw holes 215. The screws The head 31 is located in the space 114.

In order to further understand the function, technical means, and expected effects of the various elements of the present invention, the following description is further described, and it is believed that the present invention will have a deeper and more specific understanding.

When assembling, the side frame members 11 of the armrest frame 10 are fitted into the grooves 24 of the connection unit 20, and the card holders 214 in the shape of a conical block are respectively embedded in In the recessed holes 118 defined by the protrusions 117, the side frame members 11 of the armrest frame 10 and the connection unit 20 can be non-rotatably engaged and positioned.

Then, the screw portion 32 of the locking members 30 is passed through the perforations 119 and screwed into the screw holes 215 to ensure that the side frame member 11 and the connection unit 20 are firmly connected, and the side frame The structural strength of the component 11 and the connecting unit 20 is good. At this time, the blocking walls 213 are located outside the ends of the side frame members 11.

In fact, each of the connecting units 20 can be fitted with a decorative cover 40 (see an imaginary line in FIG. 3), and the portions provided with the perforations 119 'for operating the side frame member 11 can be closed. And after the assembly is completed, the screw heads 31 are hidden in the space 114, and the screw heads 31 are not directly seen from the appearance of the armrest frame 10, which has the effect of beautifying the appearance.

Therefore, even if a control panel (not shown) is installed on the armrest of the present invention, the holders 214 in the shape of a conical block are respectively embedded in the recessed holes 118 defined by the convex seats 117, so that the The side frame member 11 of the armrest frame 10 and the connection unit 20 are non-rotatably engaged with each other. The structure strength of the side frame member 11 and the connection unit 20 is good, and the armrest will not shake even after a period of use. Can extend the life of the treadmill armrest.

In summary, the treadmill handrail of the present invention has a simple overall structure, is easy to manufacture and assemble, and has a good structural strength after assembly, which can indeed achieve the purpose of the invention.

However, the above are only examples of the present invention. When the scope of implementation of the present invention cannot be limited by this, any scope of patent application and patent description according to the present invention The simple equivalent changes and modifications made in the content of the book are still within the scope of the patent of the present invention.
