Description

Technology Field

[0001] The present invention relates to a saddle for exercise equipment that is rotatable in height adjustment, and more specifically, to a saddle for exercise equipment that is rotatable in height adjustment, which allows the height adjustment of the saddle of an exercise machine used for upper or lower body exercises while seated on the saddle to be easily achieved by rotating the saddle in one direction, thereby significantly improving the height adjustment capability and convenience of the exercise machine, and enabling users to easily and simply adjust the saddle height according to their body and then proceed with exercise using the exercise machine. Background Technology

[0002] Generally, busy modern people take time to do various exercises using the equipment available at the gym to maintain their physical health, and the gym is equipped with various types of exercise equipment, such as upper body exercise equipment to strengthen upper body muscles and lower body exercise equipment to strengthen lower body muscles.

[0003] Among these exercise machines, those equipped with a chair on which the user can sit allow the user to perform muscle exercises by pulling handles located on the upper left and right sides while seated, causing weights connected to the handles to rise and fall.

[0004] For example, with the low pulley, the user sits on a chair with their chest against the backrest and grasps the provided handles with both hands. When the user pulls the handles toward their upper body, the weight connected to the handles is lifted, and when the pulled handles are pulled back, the lifted weight is lowered. In the process of repeatedly performing the pulling and pushing motions of the handles, the weight of the lifting and lowering weight is transferred to the user's upper body muscles, thereby developing the back muscles or shoulder muscles among the upper body muscles.

[0005] In addition, the Butterfly is an exercise machine that develops the user's front chest muscles and other areas; when the user sits on the chair with their back against the backrest and pushes the handles located on either side forward, the weight connected to the handles is lifted, and when the handles are pulled back, the lifted weight is lowered.

[0006] However, since the chairs provided with these exercise machines are fixed in place, there is a problem in that users with different physical conditions cannot sit in the correct posture to exercise, as the handles of the machine and the user's arms cannot be properly positioned when sitting on the fixed chair.

[0007] In other words, since physical conditions vary even among adults, resulting in unequal sitting heights, there is a problem in that when exercisers with different sitting heights sit on a chair fixed at the same height, they cannot sit in the correct posture and exercise because the lengths of the armrests and the exercisers' arms differ.

[0008] Furthermore, in order to adjust the height of the saddle equipped with conventional exercise equipment, there is a cumbersome problem in that the user must fully stand up from the saddle, pull out the fixing pin or fixing rod—which is a fixing means installed on the saddle or exercise equipment—outward, set the saddle to the desired exercise position, and then reattach the fixing means.

[0009] Accordingly, technologies are being developed to enable height adjustment of the chair, or saddle, equipped with exercise equipment.

[0010] For example, an exercise equipment chair position adjustment lever, registered patent No. 10-0922334, has been devised, which comprises a lever in which one end of a support rod is fixedly installed and a lever inclined portion is formed with one end and the other end being inclined in a diagonal shape and the lever inclined portion is in contact with the inclined portion of a support body; a support rod in which one end is fixedly installed at the center of the lever inclined portion and the other end is connected to a connecting member and a spring fixing plate is formed between the one end and the other end to support the position of a spring; a support body in which the support rod is inserted internally and one end is fixedly installed at one side of the lower part of the chair; a spring that is fitted into the support rod and supported by the spring fixing plate; a connecting member that rotatably connects one end of the support rod and the other end of a locking member; and a locking member that is inserted into the position adjustment hole and the insertion hole formed in the housing while the position adjustment hole formed in the position adjustment rod and the insertion hole formed in the housing are in contact with each other.

[0011] While this conventional technology allows for easy adjustment of the chair's position to enhance user convenience, it has the problem that the chair height cannot be adjusted according to the user's physical condition because the chair's position is limited to adjustment in the front-back and rear-side directions.

[0012] As another example, an exercise chair disclosed in Utility Model Registration No. 20-0333962 has been devised, which comprises: a seat portion formed by a bearing having a nut hole into which a knit is inserted and fastened on the lower surface, and two bearings combined and formed, with two rotation axes provided respectively at the upper and lower parts, one rotation axle being fastened to the nut hole of the seat portion and the other rotation axle being fastened to the support leg; a connecting rod having the other rotation axle of the bearing inserted and fastened at the upper part and the lower part being inserted into the upper end of the support leg portion; a connecting rod insertion hole for inserting and fixing the connecting rod; a through hole into which the backrest portion is inserted; and a backrest portion fixing member for fixing the backrest portion; a backrest seat to support the back of a seated person; a support member to fix and support the backrest seat; an insertion part bent at the lower end of the support member and inserted into the through hole of the support leg; and a leg exercise member formed to contract and extend by a spring. It consists of a backrest.

[0013] This conventional technology allows the height of a chair to be adjusted by selectively inserting a connecting rod fixing device into a plurality of holes provided in the connecting rod. However, when adjusting the height of the chair by selectively inserting the connecting rod fixing device, there is the inconvenience of the user having to first remove the connecting rod fixing device from the hole in the connecting rod, adjust the height of the chair, and then re-insert the connecting rod fixing device.

[0014] In addition, there is a problem in that convenience and usability are significantly reduced when adjusting the chair height because the user has to continuously hold the chair while reattaching the connecting bracket fixing device. Prior art literature

Specific details for implementing the invention

[0027] In addition to the above objectives, other objectives and features of the present invention will become apparent through the description of embodiments with reference to the accompanying drawings.

[0028] Unless otherwise defined, all terms used herein, including technical or scientific terms, have the same meaning as generally understood by those skilled in the art to which the present invention pertains. Terms such as those defined in commonly used dictionaries should be interpreted as having a meaning consistent with their meaning in the context of the relevant technology, and should not be interpreted in an ideal or overly formal sense unless explicitly defined in this application.

[0030] Hereinafter, a saddle for an exercise machine that is rotatable and adjustable in height according to an embodiment of the present invention will be described in more detail with reference to the attached drawings.

[0032] As described above, the present invention includes a connecting frame (10) connected to an exercise equipment frame (1). The connection between the exercise equipment frame (1) and the connecting frame (10) is not limited and can be made by a bolt connection or a welded connection.

[0033] A first sliding rod bracket (21) is provided protrudingly on the upper side of one side of the connecting frame (10) of the present invention, and a second sliding rod bracket (22) is provided protrudingly on the lower side of the connecting frame (10) so as to face the first sliding rod bracket (21).

[0034] At this time, the first sliding rod bracket (21) is provided with an upper fitting space (21b) that is extended protruding from the upper side of one side of the connecting frame (10), has one side open so that the upper end of the sliding guide rod (30) is fitted, and has an upper fitting guide groove (21a) provided at the bottom.

[0035] Additionally, the second sliding rod bracket (22) is provided with a lower fitting space (22b) having a lower fitting guide groove (22a) at the top that is positioned to face the upper fitting guide groove (21a) and is extended outward from the lower side of the connecting frame (10), with one side open so that the lower end of the sliding guide rod (30) is fitted therein.

[0036] In addition, the sliding guide rod (30) is positioned on one side of the connecting frame (10) with its upper end bolted to the first sliding rod bracket (21) and its lower end bolted to the second sliding rod bracket (22).

[0037] That is, the upper end of the sliding guide rod (30) is positioned in the upper fitting guide groove (21a) of the first sliding rod bracket (21), and the lower end of the sliding guide rod (30) is positioned in the lower fitting guide groove (22a) of the second sliding rod bracket (22). Then, when the sliding guide rod (30) is pushed toward the connecting frame (10), the upper end and the lower end of the sliding guide rod (30) are respectively fitted into the upper fitting space (21b) of the first sliding rod bracket (21) and the lower fitting space (22b) of the second sliding rod bracket (22).

[0038] Afterwards, the upper ends of the first sliding rod bracket (21) and the sliding guide rod (30) are fastened and secured using bolts, and the upper ends of the second sliding rod bracket (22) and the sliding guide rod (30) are fastened and secured.

[0039] In this way, before fixing the first sliding rod bracket (21) and the second sliding rod bracket (22) to the upper and lower ends of the sliding guide rod (30), respectively, the sliding bearing part (40) is first fitted onto the sliding guide rod (30), and the sliding bearing part (40) fitted onto the sliding guide rod (30) slides along the longitudinal direction of the sliding guide rod (30) to guide the height adjustment of the saddle (60).

[0040] In addition, a first mounting bracket (23) is provided protrudingly on the upper side of the other side of the connecting frame (10), and a second mounting bracket (24) is provided protrudingly on the lower side of the other side of the connecting frame (10) so as to face the first mounting bracket (23).

[0041] A height-variable mounting bracket (50) is connected to the first mounting bracket (23) and the second mounting bracket (24). The height-variable mounting bracket (50) has its upper surface bolted to the first mounting bracket (23) and its lower surface bolted to the second mounting bracket (24), and is positioned on the other side of the connecting frame (10) to form a vertical movement space (51) between it and the other side of the connecting frame (10), and a plurality of height-variable mounting grooves (52) are provided along the longitudinal direction.

[0042] The above saddle (60) is composed of a saddle connecting bracket (63) having a bearing member connecting member (61) on one side that is connected and fixed to the sliding bearing member (40), and a mounting fixing pin (62) on the other side that is mounted on one of the multiple height-variable mounting grooves (52) of the height-variable mounting member (50) or detached from the mounted height-variable mounting groove (52).

[0043] The bearing member (61) of the present invention is provided with a fitting protrusion (61a), and the saddle connecting bracket (63) comprises a first support angle (63a) having one side fitted into the fitting protrusion (61a) of the bearing member (61) and having its upper surface bolted to the lower end of the saddle (60), a second support angle (63b) having a mounting fixing pin (62) protruding to the other side and having its upper surface bolted to the lower end of the saddle (60) and having the mounting fixing pin (62) positioned in the height-variable mounting groove (52) of the height-variable mounting bracket (50), and the mounting fixing pin (62) positioned in the up-and-down movement space (51) formed between the connecting frame (10) and the height-variable mounting bracket (50), and a connecting support for the first support angle (63a) and the second support angle (63b). It is provided with a reinforcing support angle (63c).

[0044] In the present invention, which is constructed as described above, the saddle connecting bracket part (63) is provided with a first support angle (63a), a second support angle (63b), and a reinforcing support hanger (63c) connecting the first support angle (63a) and the second support angle (63b) on the lower surface of the saddle (60). As a result, the saddle (60) can firmly support the load while the user is sitting by the saddle connecting bracket part (63), and the saddle connecting bracket part (63) can be rotated toward the sliding guide rod (30) or toward the height-variable stand (50) by the rotational movement of the saddle (60) with the sliding bearing part (40) as an axis.

[0045] The above mounting fixing pin (62) may be integrally extended and protruded from the other side of the saddle connecting bracket part (63), or the end of the mounting fixing pin (62) may be protruded and fixed to the saddle connecting bracket part (63) by welding.

[0046] The present invention, thus made, allows the height of the saddle (60) to be easily adjusted to suit the user's physical condition before exercising using the exercise equipment, simply by rotating the saddle (60) toward the sliding guide rod (30) fitted with the sliding bearing part (40).

[0047] That is, when the saddle (60) is pushed toward the sliding guide rod (30), the saddle (60) rotates around the sliding bearing (40) as an axis, and the mounting fixing pin (62) that was mounted in one of the multiple height-variable mounting grooves (52) provided in the height-variable mounting bracket (50) is detached and separated from the height-variable mounting groove (52).

[0048] At this time, the saddle (60), from which the mounting fixing pin (62) has been detached from the height-adjustable mounting groove (52), is lifted up and down or lowered to adjust the height of the saddle (60), and then the height-adjustable saddle (60) is rotated toward the height-adjustable mounting stand (50). Then, the mounting fixing pin (62) protruding from the other side of the saddle connecting bracket part (63) connected to the bottom of the saddle (60) is mounted in the height-adjustable mounting groove (52) that corresponds to the plurality of height-adjustable mounting grooves (52) provided in the height-adjustable mounting stand (50), thereby fixing the height-adjustable saddle (60).

[0049] In this way, the present invention allows the height of the saddle (60) of an exercise machine to be easily and conveniently adjusted with only a simple operation of pushing the saddle (60) toward the sliding guide rod (30) to rotate it, raising or lowering the saddle (60) to adjust the height of the saddle (60), and then rotating the saddle (60) back toward the height-adjustable stand (50) when adjusting the height of the saddle (60), thereby greatly improving usability and convenience.

[0050] In addition, as the lifting or lowering motion of the saddle (60) is guided by the sliding bearing part (40) fitted into the sliding guide rod (30), the heavy saddle (60) can be easily lifted and lowered or lowered and lowered, so even users with relatively little physical strength can easily adjust the height of the saddle (60).

[0051] In the height-variable mounting bracket (50) of the present invention, a mounting fixing pin stopper part (53) is provided extending along the longitudinal direction of the plurality of height-variable mounting grooves (52) to prevent the saddle (60) from rotating completely toward the sliding guide rod (30) after the mounting fixing pin (62) mounted in the height-variable mounting groove (52) is detached from the height-variable mounting groove (52) and comes out of the height-variable mounting bracket (50).

[0052] The above mounting fixing pin stopper part (53) is positioned on the front side of the height-variable mounting groove (52) as shown in FIG. 2 and is connected to the upper and lower ends of the height-variable mounting bracket (50) and is provided integrally with the height-variable mounting bracket (50).

[0053] In this way, since the mounting fixing pin stopper part (53) is positioned on the front side of the multiple height-variable mounting grooves (52), as shown in FIGS. 6 and 7, it is possible to prevent the mounting fixing pin (62), which has been separated from the height-variable mounting grooves (52), from completely coming out of the height-variable mounting stand (50). Furthermore, since the range of rotation of the saddle (60) toward the sliding guide rod (30) can be interfered with, the inconvenience of the operation of mounting the mounting fixing pin (62) by connecting it to one of the multiple height-variable mounting grooves (52) after adjusting the height of the saddle (60) by excessively rotating the saddle (60) toward the sliding guide rod (30) can be prevented in advance. Additionally, when the saddle (60) is raised or lowered, the mounting fixing pin (62) is guided in a state of close contact with the inner surface of the mounting fixing pin stopper part (53). It can support the raising and lowering motion of the saddle (60).

[0054] Each of the height-variable mounting grooves (52) provided along the longitudinal direction of the height-variable mounting bracket (50) of the present invention is formed to be inclined toward the upper side. Accordingly, the mounting fixing pin (62) provided on the other side of the saddle connecting bracket part (63) of the saddle (60) can be easily separated and detached from the height-variable mounting groove (52), as well as easily inserted and mounted into the height-variable mounting groove (52).

[0055] In addition, at the inner lower side of each of the plurality of height-variable mounting grooves (52), a mounting pin seating support surface (52a) is provided, on which a mounting fixing pin (62) mounted in the height-variable mounting groove (52) is seated and supported.

[0056] Accordingly, as the mounting fixing pin (62) is mounted and supported on the inclined mounting pin seating support surface (52a) at the inner lower end of the inclined height-variable mounting groove (52), the saddle (60) can be prevented from descending while exercising while sitting on the saddle (60), thereby allowing for safe physical training using the exercise equipment.

[0058] As described above, the present invention has been explained by specific details such as specific components, limited embodiments, and drawings; however, this is provided merely to aid in a more comprehensive understanding of the invention, and the invention is not limited to the above embodiments. Those skilled in the art can make various modifications and variations from this description.

[0059] Accordingly, the scope of the present invention should not be limited to the described embodiments, and all things equivalent to or having equivalent variations to the claims set forth below, as well as the claims set forth below, shall be considered to fall within the scope of the concept of the present invention.
