Description

Positionable folding frame

The present application provides a positionable folding frame that is associated with a storage assembly that can be placed in an extended or pivoted manner.

The general folding frame body 10 is pivotally extended or closed as shown in the first and second figures. The frame body 10 is stretched into a use state, and the folding body is folded to be in a non-use state. The frame body 10 is not provided with a positioning structure. After the storage and closure, a storage bag 11 must be used to restrict the frame body 10 from being freely extended and opened, which is very inconvenient to use.

The present invention provides a positionable folding frame whose main purpose is to improve the lack of positioning of the conventional folding frame body and the trouble of storage.

In order to achieve the above objective, the present invention provides a positionable folding frame, comprising: a frame body, which is formed by four quadrangular rods arranged in a rectangular shape, and each of the struts is slidably disposed with one The sliders of the holes are arranged, and the fork groups are respectively disposed between the two poles, and the fork groups are composed of two pivotal cross-connections, and the two ends of the pivots are respectively pivotally connected to the poles and the poles a first positioning hole and a second positioning hole are disposed on the pole; and a positioning unit includes a component, an insert, a spring, a sleeve and an operating member disposed on the slider, The fixing member is a nut and is fixedly disposed on the slider relative to the position of the set of holes. The two ends of the insert are respectively an insertion end and a driving end. The insert has a shoulder between the two ends, and the sleeve is The hollow structure has a head end and a fixed end, the fixed end has a receiving portion, the receiving portion has an abutting surface, the driving end penetrates the spring and penetrates into the receiving portion, so that the two springs The ends are respectively abutted against the shoulder and the abutting surface, and the driving end of the insert passes through the head end and the As a member fixedly connected to the positioning unit and then through a fixed end fixed to the kit is the set of apertures provided.

By positioning the positioning unit on the slider, the positioning unit can be pulled to release the positioning or release the positioning hole to form a positioning, thereby locating the state of the frame, improving stability and safety during use, and conveniently when not in use. Store it.

A preferred embodiment of the presently configurable folding frame, as shown in Figures 3 to 8, comprises: a frame 20, which is formed by four quadrangular rods 21 arranged in a rectangular shape, which are pivotally connected to the four-pronged rod group 22, and each of the rods A slider 23 is slidably disposed on the other end of the struts 21, and a pulley 24 is disposed on each of the other ends of the struts 21, and each of the yoke groups 22 is disposed between the two struts 21, and each of the yoke groups 22 is provided by two struts The 221 cross-pivot is formed, and the two ends of the pivots 221 are respectively pivotally connected to the strut 21 and the slider 23, and the pivoting of the pivot rod 221 and the sliding of the sliders 23 on the strut 21 respectively cause each The struts 21 are relatively close to or away from each other; one of the struts 21 is provided with a first locating hole 213 and a second locating hole 214, and the struts 21 of the first locating hole 213 and the second locating hole 214 are disposed. The slider 23 has a plurality of holes 231; and a positioning unit 30 is disposed on the slider 23 having the set hole 231, and the positioning unit 30 includes a component 31, a card 32, a spring 33, and a Kit 34 and an operation And the fixing member 31 is a nut and is fixedly disposed on the slider 23 at a position opposite to the set hole 231. The two ends of the insert 32 are respectively an insertion end 321 and a driving end 322, and the insert 32 is There is a shoulder 323 between the two ends. The sleeve 34 has a hollow structure and has a front end 341 and a fixed end 342. The fixed end 342 has a receiving portion 343. The receiving portion 343 has an abutting surface 344. The driving end 322 is inserted into the accommodating portion 343, and the two ends of the spring 33 are respectively abutted against the shoulder portion 323 and the abutting surface 344, and the driving end 322 of the insert 32 is worn. The head end 341 is fixedly connected to the operating member 35, and the positioning unit 30 is fixed to the set hole 231 through the fixed end 342 of the sleeve 34.

The above is the structural configuration and characteristics of the foldable frame that can be positioned by the author, and its use As shown in FIG. 3, the frame 20 is in an extended state as shown in FIG. 3. The insertion end 321 of the insert 32 of the positioning unit 30 is inserted and positioned in the second positioning hole 214. When the frame 20 is to be received, the insert 32 is moved to move away from the second positioning hole 214 by pulling the operating member 35, and the spring is compressed by the shoulder 323 when the insert 32 moves. 33. When the insertion end 321 of the insert 32 is disengaged from the second positioning hole 214, the slider 23 loses the positioning force, and the user can move the rods 21 through the pivoting of the fork groups 22 The sliders 23 are slid along the struts 21 and finally become the accommodating and slidable state. When the sliders 23 are slid to the position relative to the first locating holes 213, the operating members 35 can be loosened and pulled. The force of the spring 33 is reset, and the insertion end 321 of the insert 32 is inserted into the first positioning hole 213 to form a positioning; as can be seen from the above, the present invention can be positioned in the state of being stretched or closed and stored. In the state, it can avoid improper closeness and improve the stability and safety of use. In the state of use, the occupied space can be reduced, and the convenience of storage can be improved.

In addition, as shown in FIG. 9, the two ends of a return spring 50 are respectively fixed. Provided on the support rod 21 and the slider 23, when the frame body 20 is in the storage and close-up state, the return spring 50 is stretched and stored; and when the positioning of the positioning unit 30 is released, the frame body 20 is stretched, The return spring 50 is elastically reset and assists the rapid expansion of each of the fork sets 22 to be in a use state. As shown in FIG. 10, the convenience of use is high; further, each of the strut 21 and the fork set 22 of the above embodiment are Taking a square tube as an illustration, the tube shape can also be set as a circular rod as shown in Fig. 11, and the same purpose and effect as the above embodiment can be achieved.
