Description
- The present invention belongs to the technical field of exercise equipment and relates to a horizontal bar device, and more particularly to a horizontal bar device capable of height adjustment.
- With the continuous development of technology, people gradually pay more attention to physical exercise, but for various reasons, most people do not want or are not willing to exercise in the gym, but prefer to buy home fitness equipment and exercise directly at home.
- The existing horizontal bar frame is a relatively common fitness equipment. When the horizontal bar frame is installed indoors, the height of the horizontal bar needs to be adjusted often due to different heights of the people using it. The existing horizontal bar frames generally use holes in the mounting tube, the horizontal bar is plug-connected into the holes of corresponding height, and the horizontal bar is fixed to the mounting tube by bolts. For example, Chinese patent application (application No.
CN201420167172.3 - Since the human hands hold onto the horizontal bar during use, the horizontal bar is subjected to vertical downward acting force, and the locking screws lock the sleeves on the vertical columns in the radial direction of the vertical columns, the positions where the locking screws contact the sleeves are subjected to downward pulling stress, and long-term use will cause the locking screws at the portions to be easily deformed and broken. Since the horizontal bar is a straight rod, when a person performs actions on the horizontal bar, the horizontal bar is deformed downwardly at the portion where force is exerted, thereby the sleeves at both ends of the horizontal bar are pulled inwardly, resulting in the tendency of the locking screws to move outward relative to the sleeves, it is easy for the locking screws to disengage from the vertical columns, or it is easy for them to break, which makes the stability of the horizontal bar frame worse. Furthermore, when the horizontal bar frame is not used, the horizontal bar frame can only be completely disassembled and stored, which makes the assembling, disassembling and storage of the horizontal bar frame inconvenient.
- One object of one embodiment of the present invention is to solve the above problems in the prior art by providing a horizontal bar device. The technical problems to be solved by the present invention are how to make the horizontal bar convenient to adjust while improving the stability.
- One object of one embodiment of the present invention can be achieved by the following technical solutions: a horizontal bar device, comprising at least three vertically disposed struts, and crossbars connected between the two adjacent struts, characterized in that a plurality of sleeves are sleeved on an upper part of each of the struts with the sleeves being stacked on top of one another, each end of each of the crossbars is fixedly connected to one of the sleeves, and each of the struts has a blocking surface capable of preventing the sleeves from sliding downward.
- One embodiment of the three struts can form a three-dimensional frame, and more than three of the struts, such as four or five, can also form a three-dimensional frame to stand up on the ground. The two ends of the crossbar are fixedly connected with the sleeves, and the crossbars are disposed on the struts with the sleeves being stacked on top of one another over the struts. Different stacking orders of the sleeves will produce different heights of the crossbars, and the way in which the sleeves being stacked on top of one another replaces the fixing method of pin insertion. The crossbars are horizontally connected, and the force exerted on the sleeve is only in the axial direction of the sleeve without radial shearing force, which improves the stability.
- According to one embodiment of the horizontal bar device described above, the blocking surface can be an annular surface on the strut abutting against a lower end surface of the sleeve, and the annular surface can be an end surface of a tube body or a shoulder formed by compression, or an externally connected shoulder. The blocking surface can also be a convex pin or blocker connected to the strut.
- According to one embodiment of the horizontal bar device described above, the sleeves stacking on top of one another are pressed firmly against the blocking surface by a locking sleeve and a fastener, and a positioning structure is disposed between the two adjacent sleeves capable of preventing rotation of the sleeves. Positioning of the positioning structure can be released after the fastener is loosened, and more than four of the struts can be folded, because the two ends of the crossbar are pivotally connected to the struts via the sleeves, and more than four of the crossbars form a movable polygon structure, while the positioning structure can improve the stability of the unfolded horizontal bar device.
- According to one embodiment of the horizontal bar device described above, the shape of the strut is also improved, a leg tube of the strut comprises an inclined portion, the inclined portion can be formed into a segmented structure or an integral structure. An upper end of the inclined portion is bent upwardly to form a vertical mounting portion, and a lower end thereof is bent downwardly to form a vertical support portion. The support portion is connected with a footing, an upper surface of each of the footings has a vertical connector, and the support portion is plug-connected to the connector.
- One embodiment of the segmented inclined portion comprises at least two tube bodies, and the two neighboring tube bodies are connected, with connection being made through their respective plug-connection to a connecting tube in-between, and such structure allows greater height adjustment.
- Compared with the prior art, one embodiment of the horizontal bar device of the present invention has the following advantages:
- 1. During use, the human hands hold onto the crossbar, and the crossbar is subjected to vertical downward acting force, so that the sleeves connected to the crossbar are pressured downwardly, and the force exerted is only in the axial direction of the sleeves without radial shearing force. When the stacked sleeves transmit the force to the blocking structure, because the blocking surface is an annular surface, especially the annular surface formed by an end surface of the strut, the force exerted is also along the axial direction, and therefore the stability is very high. The fastener connected to the locking sleeve is only subjected to its own tightening force, and is not subjected to the shearing force and thrust of the sleeve connected with the crossbar, thereby ensuring the stability of the connection.
- 2. The fastener is rotated to move outward a certain distance. At this time, the sleeves and the locking sleeve are both loosened, and the two diagonal struts are drawn close to each other by an external force. After the two diagonal struts abut with each other, the entire horizontal bar device is flat, and the horizontal bar device is convenient for folding and storage.

- One embodiment of a horizontal bar device is a three-dimensional frame that can be folded, or disassembled to be stored, or unfolded to be placed on a horizontal ground. As shown in
FIG. 1 , the unfolded three-dimensional frame comprises fourstruts 1 with a rectangular distribution. An upper end portion of each of thestruts 1 is sleeved withcylindrical sleeves 2, and other tubular structures, such as ones with rectangular outside surface, can also be used as a shape for thesleeve 2. Thesleeves 2 are stacked on top of one another, andcrossbars 3 are disposed between the twoadjacent struts 1, and eachend 31 of each of thecrossbars 3 is fixedly connected to one of thesleeves 2 so that each of thecrossbars 3 can independently slide upward and downward along thestruts 1. Thecrossbar 3 can be fixedly connected with thesleeves 2 by welding, or by integral manufacturing. The twoends 31 of thecrossbar 3 are bent downwardly so that thecrossbar 3 has an arch structure, and the direction of the arch shape is vertical. The arch structure is set in such a way that, after a middle portion of thecrossbar 3 is subjected to vertical downward acting force during use, since the twoends 31 of thecrossbar 3 are formed as bent portions, the stress is concentrated on the bent positions of thecrossbar 3, and therefore the middle portion of thecrossbar 3 is not easily deformed. - An outer peripheral surface of the upper end portion of one embodiment of the
strut 1 has a blocking surface13 capable of preventing thesleeves 2 from sliding downward. More than two of thesleeve 2 on each of thestruts 1 is provided, and thebottommost sleeve 2 abuts against the blocking surface13. An upper end of thestrut 1 is sleeved with alocking sleeve 4 that cooperates with the blocking surface13 to press thesleeves 2 tightly, and thelocking sleeve 4 is locked on thestrut 1 by afastener 5. - As shown in
FIGS. 2 and3 , one embodiment of the blocking surface13 is anannular surface 6 on thestrut 1, and a section A at the upper left corner ofFIG. 2 is a perspective view with some of thesleeves 2 being separated, andFIG. 3 is an enlarged view of the section A ofFIG. 2 . Each of thestruts 1 further includes a leg tube 1a and astraight tube 1b, refer toFIG. 5 for a detailed cross-sectional view. Thestraight tube 1b is inserted and fixed in an upper end of the leg tube 1a, and theannular surface 6 is an annular end surface 1a4 of the upper end of the leg tube 1a. Thesleeves 2 have a same size and are stacked on top of one another over thestraight tube 1b, and alower end surface 2a of thebottommost sleeve 2 is stacked up over theannular surface 6. Thus, thesleeves 2 are blocked from moving downward, and since the blocking surface13 uses an upper end surface of the leg tube 1a, the leg tube 1a is also subjected to axial force when the force is exerted, thereby eliminating the radial force and improving the stability when the force is exerted. - In order to further improve the stability, as shown in
FIG. 3 , and in one embodiment of the sleeves, a positioning structure is disposed between twoadjacent sleeves 2 capable of preventing rotation of thesleeves 2. The positioning structure comprises anotch 7 disposed at an upper end surface of thesleeve 2 and abulge 8 disposed at alower end surface 2a of thesleeve 2, and thebulge 8 and thenotch 7 between the twoadjacent sleeves 2 interlock with each other. A plurality of thenotches 7 and thebulges 8 on thesleeve 2 are evenly distributed circumferentially. Theannular surface 6 is disposed with thenotches 7 capable of preventing thesleeve 2 from rotating. Thenotch 7 and thebulge 8 can be in any shapes, and thenotch 7 and thebulge 8 can be swapped for achieving the same positioning effect. Thesleeves 2 are circumferentially restrained on thestrut 1, and thesleeves 2 cannot be rotated relative to thestrut 1 for improving the stability. - When the horizontal bar device is unfolded to form the three-dimensional frame, as shown in
FIG. 5 , one embodiment of anut 11 is fixedly connected inside an upper end of thestraight tube 1b. The lockingsleeve 4 is sleeved on the upper end of thestraight tube 1b, and an upper end surface of the lockingsleeve 4 is a pressedsurface 4a. Thefastener 5 is a bolt, a brim of the bolt is pressed against the pressedsurface 4a, and a lower end of the bolt passes through the pressedsurface 4a and is connected to thenut 11 inside thestraight tube 1b of thestrut 1 through threads. Aspring washer 12 sleeved on the bolt is provided between the brim of the bolt and the pressedsurface 4a, and thespring washer 12 is abutted against the brim of the bolt and the pressedsurface 4a. After tightening the bolt, thesleeves 2 are sandwiched tightly between the lockingsleeve 4 and the blocking surface 13, and under the positioning of the positioning structure, the horizontal bar device which is unfolded into the three-dimensional frame forms a very stable structure. - One embodiment of the
sleeves 2 sleeved over thestraight tube 1b are rotatable with thestraight tube 1b as an axis. When the horizontal bar device needs to be folded for storage, thefastener 5 is unscrewed loose to release the pressing state of the lockingsleeve 4, so that sufficient clearance is provided between thesleeves 2 to release the restriction of the positioning structure in order to allow thesleeves 2 to be capable of rotating freely. Then, the twodiagonal struts 1 are pressed towards the center and close to each other, and the other twodiagonal struts 1 are moved outwardly away from each other, thereby the horizontal bar device is folded flatly to be stored away. - For ease of storage, as shown in
FIGS. 1 and2 , one embodiment of the fourstruts 1 are tubular rods, each of thestruts 1 includes the leg tube 1a. Referring to the leg tube 1a on the left side inFIG. 2 , which includes an inclined portion 1a1, an upper end of the inclined portion 1a1 is bent upwardly to form a vertical mounting portion 1a2, and a lower end thereof is bent downwardly to form a vertical support portion 1a3. The fourstruts 1 form a pyramid-shaped structure, and the horizontal bar device is not easily shaken during use. The mounting portion 1a2 has a tube section with an inner diameter smaller than an inner diameter of the inclined portion 1a1, and thestraight tube 1b is plug-connected into the mounting portion 1a2 by tight fit. The support portion 1a3 is connected with afooting 9, an upper surface of each of thefootings 9 has avertical connector 9a, and the support portion 1a3 is plug-connected to theconnector 9a. The fourfootings 9 are evenly divided into two groups, each of the groups of thefootings 9 is connected by atie rod 10, and the twostruts 1 on each pair of thefootings 9 are connected integrally by thetie rod 10 so that thediagonal struts 1 are further prevented from drawing close to each other with an external force, thereby improving the stability of the use of the horizontal bar device. - The horizontal bar device is placed on a flat ground for use, one embodiment of the
sleeves 2 are sleeved all together on top of one another on thestrut 1, and thesleeves 2 of each of thecrossbars 3 are sleeved at corresponding heights as needed. Then the lockingsleeve 4 is sleeved, and thesleeves 2 are pressed tightly between the blocking surface13 and the lockingsleeve 4 by thefastener 5. By the positioning structure, thesleeves 2 cannot be rotated relative to thestrut 1, and finally thefootings 9 are plug-connected to form the stable three-dimensional frame. During use, the human hands hold onto thecrossbar 3, and thecrossbar 3 is subjected to vertical downward acting force, so that thesleeves 2 connected to thecrossbar 3 are pressured downwardly without being pushed upwardly. At this time, thefastener 5 connected to the lockingsleeve 4 is only subjected to its own tightening force, and is not subjected to the shearing force and thrust of thesleeve 2 connected with thecrossbar 3. During use, thefastener 5 and thestrut 1 are thread connected more securely, which prevents thefastener 5 from loosening during use, and improves the stability of the horizontal bar device. In addition, some of thesleeves 2 are fixedly connected with thecrossbar 3, and some of thesleeves 2 are not fixedly connected with thecrossbar 3, so it is only necessary to take out thefastener 5, to take out the lockingsleeve 4, to take out thesleeves 2 to be adjusted , and then thesleeves 2 can be re-arranged and combined as needed to achieve height adjustment of thecrossbars 3. - When the horizontal bar device is not in use, one embodiment of the
fastener 5 is unscrewed to retract outward a certain distance. At this time, thesleeves 2 and the lockingsleeve 4 are both loosened, and both thesleeves 2 and the lockingsleeve 4 are rotatable relative to thestrut 1 and are capable of sliding upward and downward along thestrut 1. The twodiagonal struts 1 are drawn close to each other by an external force. After the twodiagonal struts 1 abut with each other, the entire horizontal bar device is flat, and the horizontal bar device is convenient for folding and storage. - The
embodiment 2 is basically the same as theembodiment 1, the difference lie in the blocking surface13 as shown inFIG. 6 . The blocking surface13 is a shoulder of thestrut 1, theannular surface 6 is a shouldering surface 1a5, and thesleeve 2 abuts against the shouldering surface 1a5; or the blocking surface13 is a convex blocker 1a6 connected to thestrut 1, as shown inFIG. 7 . - The
embodiment 3 is basically the same as theembodiment 1, as shown inFIG. 8 and FIG. 9 , the differences lie in that, the inclined portion 1a1 comprises at least two tube bodies 1a11, and the two neighboring tube bodies 1a11 are connected, with connection being made through their respective plug-connection to a connecting tube 1a7 in-between. The connecting tube 1a7 and one of the tube bodies 1a11 are fixedly connected by welding, and the connecting tube 1a7 and the other tube body 1a11 are connected by ascrew 15. - The
embodiment 4 is basically the same as theembodiment 1, as shown inFIG. 10 , the differences lie in that, the twoadjacent struts 1 are connected by the twocrossbars 3 in-between. Thelower crossbar 3 is a straight rod with the two ends being connected to thebottommost sleeves 2, and the two ends 31 of theupper crossbar 3 are bent so that thecrossbar 3 has an arch structure. The arch structure extends horizontally inward toward the three-dimensional frame, and theupper crossbar 3 is connected to thetopmost sleeves 2. - The specific embodiments described herein are merely illustrative of the spirit of the present invention. Technical personnel skilled in the art to which the present invention pertains can make various modifications or additions to the specific embodiments described or replace them in a similar manner, without departing from the spirit of the present invention or beyond the scope defined by the appended claims.
