Technical field

The invention relates to the field of support mechanisms, and in particular to a skeleton. The invention also relates to an umbrella having the above skeleton and a canopy having the above skeleton.

Background technique

Umbrellas and awnings are indispensable items in life, and the structure of the skeleton has a great influence on its scope of use and performance.

The skeleton of the commonly used umbrella and canopy has two structural forms.

Referring to Figure 1, Figure 1 is a schematic view of a typical skeleton.

As shown in FIG. 1, the first type of skeleton includes a main strut 1, an upper fixing member 2, a main center rod 3, a push handle 4, a sub-center rod 5, a diagonal support hole 6, a middle tab 7 and a sub-strut 8. The end of the main strut 1 is hinged to the upper fixing member 2, the substrut 8 is hinged to the middle tab 7, and the middle tab 7 is fixed to the main strut 1. A main center rod 3 is fixed at a lower end thereof along the axial direction of the upper fixing member 2, and the main center rod 3 is provided with a diagonal supporting hole 6 for the diagonal bracing, and the inclined supporting hole 6 is a threaded hole whose axis is biased toward the main center rod The lower end of 3. The lower end portion of the main center rod 3 is connected to the sub center rod 5 by a thread, the axes of which are in a straight line, and the diameters of the two are equal. The threads on the secondary center rod 5 can cooperate with the threads of the diagonal support holes 6. The push handle 4 is movably sleeved on the sub-center rod 5, and its upper end is hinged to the sub-strut 8. The lower end of the main center rod 3 is provided with a card slot, and the upper end of the push handle 4 is internally provided with a plastic member matched with the card slot. The skeleton can be used for the support of an umbrella or canopy. When the umbrella or the canopy to which the above-described skeleton is applied is in the stowed state, the push handle 4 is located at the lower end of the sub-center bar 5, so that the main strut 1, the sub-strut 8 and the main center bar 3 are in a nearly parallel position. When the umbrella or canopy needs to be opened, push the push handle 4 up along the secondary center rod 5 until the plastic piece inside the push handle 4 is engaged with the card slot on the main center rod 3, and the umbrella or canopy is in operation. status. Sometimes, in order to block sunlight or wind and rain in different directions, it is necessary to change the opening angle of the umbrella or canopy, that is, the bracing. At this time, the sub-center rod 5 can be unscrewed from the main center rod 3 and screwed into the inclined support hole. Within 6, the diagonal support of the umbrella or canopy can be realized.

In the above skeleton, in order to ensure the strength of the skeleton, the main center rod 3 is generally long, and the triangle formed by the main strut 1, the main center rod 3 and the sub strut 8 is an acute triangle, which causes the top of the umbrella or the canopy to be There is a large space that cannot be used, resulting in wasted space. Moreover, the skeleton is not convenient when the diagonal bracing is realized, and the supporting strength of the sub-center rod 5 is not guaranteed, and the practicality is not very strong.

Referring to Figure 2, Figure 2 is a schematic view of the structure of another typical skeleton.

As shown in Fig. 2, the second skeleton is based on the first skeleton and focuses on the improvement of the skeleton bracing mechanism. The structure of the skeleton is similar to that of the first skeleton, except that the skeleton further includes an upper joint 9, a lower joint 10 and a sleeve 15, the main center rod 3 is fixedly connected with the upper joint 9, and the sub-center rod 5 is fixed to the lower joint 10. The upper joint 9 and the lower joint 10 are hinged, the sleeve 15 is sleeved on the upper joint 9 and the lower joint 10, and the end of the upper joint 9 is provided with an angled chamfer. In the normal open state of the umbrella or canopy, due to the action of the sleeve 15, the axes of the upper joint 9 and the lower joint 10 are on the same straight line, and the main center rod 3 and the sub-center rod 5 are also in the same straight line, thereby realizing the umbrella. Or the straight support of the canopy.

Referring to Figure 3, Figure 3 is a schematic view of the state of the skeleton bracing shown in Figure 2.

In Fig. 3, when the umbrella or canopy needs to be braced, after the sleeve 15 is lifted up a certain distance, the sub-center rod 5 is rotated around the hinge line of the upper joint 9 and the lower joint 10, so that the upper joint 9 and the lower joint The contact surface of the joint 10 becomes a chamfered portion, and the diagonal stay can be realized.

Compared with the first skeleton, the second skeleton is more convenient to realize the operation of the diagonal bracing, but the skeleton structure still makes the space occupied by the umbrella or the canopy top larger, and the space waste problem is not greatly improved. Moreover, the strength of the truss structure is poor, and the safety of the umbrella or the canopy cannot be guaranteed. How to reduce the space occupied by the skeleton has become a technical problem that a person skilled in the art urgently needs to solve. Summary of the invention

detailed description

The core of the invention is to provide a skeleton, which reduces the space occupied by the skeleton, facilitates the diagonal bracing, ensures the strength of the diagonal bracing, and enhances its practicability. Another core of the present invention is to provide an umbrella comprising the above skeleton and a canopy comprising the above skeleton.

In order to make those skilled in the art better understand the solutions provided by the present invention, the present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

Referring to FIG. 4, FIG. 4 is a schematic structural view of a skeleton provided by the present invention.

As shown in FIG. 4, in a specific embodiment, the skeleton provided by the present invention includes a main strut 1, an upper fixing member 2, a main center rod 3, a push handle 4, a middle tab 7 and an auxiliary strut 8, The strut 1 is hinged to the sub-strut 8 through the middle tab 7, the upper end of the main center rod 3 is fixed to the upper fixing member 2, the push handle 4 is hinged to the end of the auxiliary strut 8, and the push handle 4 and the main center rod 3 are Coaxial, and the diameter of the inner hole is larger than the diameter of the main center 4 dry 3 .

Referring to FIG. 5, FIG. 5 is a schematic view showing a state in which the skeleton is stored according to the present invention.

In Fig. 5, when the skeleton is in the storage state, the push handle 4 is separated from the main center rod 3 and is at a lower position. At this time, the main strut 1 and the main center rod 3, the sub strut 8 and the main center rod 3 are both In order to be close to the parallel state, it is convenient to carry the skeleton.

Referring to FIG. 6, FIG. 6 is a schematic view showing a state in which the skeleton is opened when the present invention is provided.

In Fig. 6, when the skeleton provided by the present invention needs to be opened, the push handle 4 is pushed up to move upward. And splicing with the main center rod 3, and continuing to push up until the triangle formed by the main center rod 3, the main struts 1 and the auxiliary struts 8, the inner angle composed of the auxiliary struts 8 and the main center rod 3 is an obtuse angle . In this state, due to the restraining action of the fabric on the skeleton on the main strut 1, the direction of the supporting force of the substrut 8 against the pusher 4 is opposite to the direction of the conventional skeleton force, so even if the external force is lost, the secondary strut 8 It is also provided to push the push handle 4 so that the push handle 4 comes into contact with the lower end surface of the upper fixing member 2, and is maintained in this state, thereby completing the distraction process of the skeleton.

Obviously, this structure utilizes the interaction force between the internal structures of the skeleton to maintain the skeleton opening, without the auxiliary structure, the number of parts is small, and the operation is convenient.

As can be seen from the above description, the skeleton provided by the present invention causes the upper fixing member 2 and the push handle 4 to directly contact, shortening the distance between the upper fixing member 2 and the push handle 4, thereby shortening the length of the main center rod 3, The space occupied by the skeleton is reduced, the use space inside the skeleton is increased, and the practicability is improved.

In Fig. 4, in order to make the skeleton provided by the present invention safer in use, the skeleton further includes a connecting rod 13 and a hook 14, and the connecting rod 13 is fixed to the upper fixing member 2, and the hook 14 is coupled to the connecting rod 13. After the skeleton is opened, the hook 14 is hooked in the hole provided in the push handle 4, and a certain pulling force is applied to the skeleton. Even if a wind blows or other conditions occur, the skeleton does not collapse, making the entire skeleton more reliable and improving. The safety of the use of the skeleton.

In the specific implementation process, the umbrella or canopy supported by the above skeleton usually needs to add an auxiliary supporting mechanism on the side of the umbrella or the canopy to realize the function of shielding sunlight or wind and rain, and in some occasions, a supporting mechanism is needed in the middle of the umbrella or the canopy. Therefore, in order to make the above-mentioned skeleton more convenient to be used in this case, the skeleton is further provided with a sub-center rod 5 which is on the same axis as the main center rod 3, and both of which are connected by a screw. At this time, the push handle 4 can be directly sleeved on the sub-center rod 5, so when the push handle 4 is pushed, the sub-center rod 5 is equivalent to the guide rod, and the positioning is convenient. Obviously, the support can be achieved by attaching the sub-center rod 5 to the main center rod 3. After the sub-center rod 5 is unscrewed, the skeleton can be used for other support forms.

When the main center rod 3 and the sub center rod 5 described above are screwed, the main center rod 3 is generally solid and has a high strength.

In a specific embodiment, the movable connection of the main center rod 3 and the sub-center rod 5 can also be realized by a telescopic structure, that is, the diameter of the main center rod 3 is larger than the diameter of the sub-center rod 5, and the sub-center rod is required. 5 When the support is taken out, the sub-center rod 5 can be pulled out, and the sub-center rod 5 can be pushed into the main center rod 3 when not needed. The locking between the main center rod 3 and the sub-center rod 5 can be achieved by a conventional telescopic mechanism locking method. It can be seen that it is convenient to operate in this manner, but since the main center rod 3 is hollow, the diameter of the main center rod 3 is required to be high.

Referring to Fig. 7, Fig. 7 is a schematic view showing the state of the skeleton bracing provided by the present invention.

When the umbrella or the awning is used in a specific manner, the angle of the internal structure is usually adjusted according to the direction of the occluded object, so as to achieve maximum shielding. Therefore, the skeleton provided by the present invention is also provided with a struts for changing the support angle of the skeleton. mechanism. Specifically, the skeleton fixes the connecting member 17 at the lower end of the main center rod 3, and respectively provides axial through holes and radial through holes at the tail portions thereof in the axial direction and the radial direction of the connecting member 17, and the lower end of the axial through holes A flange is disposed therein, and a screw 11 is hinged therein, and the screw 11 and the sub-center rod 5 are screwed, one end of the radial through hole is chamfered, and the other end is provided with a plane along a radial direction thereof.

When the diagonal bracing is required, after the sub-center rod 5 is twisted to be displaced from the connecting member 17, the sub-center rod 5 is rotated in the plane formed by the connecting member 17 and the sub-center rod 5 to be connected to the connecting member 17 The chamfered end faces of the radial through holes are in contact, and then the sub-center rod 5 is reversely twisted to lock the skeleton, thereby achieving the diagonal bracing, and the strength of the bracing is ensured, thereby avoiding the sudden collapse of the skeleton, further increasing the safety of use. .

In addition to the diagonal support of the umbrella or the canopy, the above-mentioned diagonal bracing mechanism can further take the operation to increase the internal use space of the umbrella or the canopy. Referring to Fig. 8, Fig. 8 is a schematic view showing the state in which the sub-center rod is folded through 90°.

As shown in FIG. 8, specifically, after the sub-center rod 5 is screwed to a certain distance from the connecting member 17, the sub-center rod 5 is rotated so that its end surface is in contact with the plane on the radial through hole of the connecting member 17. Therefore, the angle formed by the sub-center rod 5 and the connecting member 17 is close to 90. , further reducing the space occupied by the skeleton. At the same time, this structure can lock the position of the push handle 4 to a certain extent, so that the working state of the umbrella or the canopy is more stable. The above structure is more widely used on the canopy.

For ease of replacement, the skeleton also includes a joint 12 at the center of which is provided with internal threads for connection to the screw 11. The joint 12 and the secondary center rod 5 are fixed by an interference fit or a pin. At this time, the screw 11 can be coupled to the sub center rod 5 through the joint 12. When there is a problem with the connection between the screw 11 and the joint 12, it is only necessary to replace the joint 12 without replacing the sub-center rod 5, Low maintenance costs.

It will be understood that the main strut 1 in the skeleton is generally relatively long, so that in order to reduce the size of the skeleton when it is in the stowed state, some improvement is required. To this end, the main strut 1 in the skeleton can be provided as a telescopic rod, and the length of the main strut 1 is reduced by the telescopic structure. Preferably, the main strut 1 can also be provided in a foldable configuration. Specifically, the main strut 1 may be composed of a plurality of strut members, the specific number of which may be determined depending on the conditions of use. The following is an example in which the main strut 1 is composed of two strut members as an example. Referring to Figure 9, Figure 9 is a schematic view showing the structure of the first main strut and the second main strut in the skeleton provided by the present invention.

As shown in FIG. 9, the main strut 1 in the skeleton is composed of a first main strut la and a second main strut lb, both of which are hinged to the connecting casing 16, and the connecting casing 16 is located at the middle connecting piece Below the 7th. When the skeleton is received, the first main strut 1a and the second main strut lb are folded, thereby significantly reducing the space occupied by the main strut 1 during storage, and facilitating the storage and transportation of the umbrella or the canopy. .

In Fig. 9, the sub-center rod 5 can be further configured as a telescopic rod, so that the support height of the skeleton can be adjusted according to different use occasions, thereby further improving the practicability of the skeleton.

The number of main struts 1 and sub struts 8 provided by the present invention is generally 4, 6, 8 or others. Depending on the function, a different number of rods can be used, and the length of the rod can also be varied to derive a variety of skeletal structures.
