Abstract

The present invention provides an automatic anti-tip device for ratchet pawl clutch, which can be easily installed in a wheelchair, a cart, an electric gate, a box and a cabinet. If the object does not tip, the device always points to the ground due to gravity and the ratchet and pawl keep separation. When the object is tipped, the device and the object intersect at an angle due to gravity, and the support element of the device is generated support-force by touching the ground. By the support-force, the pawl is automatically inserted into the ratchet by connecting telescopic pole module. The pawl is embedded to the ratchet which is fixed to the shaft, so the device can prevent the object to tip. The device comprises at least: (a) A ratchet pawl clutch module, the main function of which is used that the pawl is embedded to the ratchet to prevent the object to tip. (b) A connecting telescopic pole module, which is primarily connected to the pawl and the support element and can adjust height depends on the object. (c) A support element, the main function of which generates support-force when the support element touches the ground. By the support-force, let the pawl be inserted into the ratchet by the connecting telescopic pole module. The ratchet is fixed to the shaft, so the device can prevent the object to tip.

Description

 Automatic anti-tip device for ratchet clutch  

The invention provides an automatic anti-tip device for a ratchet clutch, which mainly uses a ratchet and pawl clutching manner to prevent an object from falling over; referring to FIG. 2 and FIG. 3, if the object is not dumped, the device is always directed to the ground due to gravity. Heart, at this time the ratchet and pawl are in a state of separation. When the object is dumped, the device forms an angle with the object due to gravity, and the supporting force generated when the supporting member of the device contacts the ground, by connecting the telescopic rod group and the spring, in addition to the shock absorber, the spine is automatically The claw is inserted into the ratchet, and the ratchet and the pawl are in a state of being embedded, and since the ratchet is fixed on the shaft, the object can be prevented from falling over.

In addition to connecting the pawl and the supporting member, the connecting telescopic rod group can adjust the appropriate height according to the object, and the supporting force generated by the supporting member when contacting the ground, the ratchet is inserted into the ratchet by connecting the telescopic rod group, the ratchet and the ratchet The pawls are embedded in each other to automatically prevent objects from falling over. Depending on the use of the object, the support element can be a movable support element, the object will also move when it is dumped, and the support element will be fixed. The object will not move when it is dumped, because the automatic anti-tip device of the ratchet clutch is installed in the object, so it is installed in There is no trouble in the box or cabinet that cannot be moved.

It is well known that when an object is dumped, it occurs instantaneously, and as a result, it often causes personal injury. The current anti-roll device is an anti-tip device designed for the same product of the same nature, such as an anti-roll device for a wheelchair and an anti-tip device for a cabinet. The automatic anti-tip device of the ratchet clutch of the invention can install all objects, and has wide applicability, and is not limited to the same type of products.

At present, the anti-roll device of the wheelchair is provided with an extension rod at the rear, but when the slope is encountered, the added extension rod is often stuck, and the action is very inconvenient. The anti-tilt device of the cabinet is to fix the cabinet on the wall or the ground. Although it can achieve anti-tilting, it is not only easy to move, but also destroys the beauty of the wall and the ground.

The automatic anti-tip device of the ratchet clutch of the invention can be installed with various objects and has wide applicability. The ratchet and pawl clutching method is used to prevent the object from falling; if the object is not dumped, the device is always directed to the center of the earth due to the influence of gravity, and the ratchet and the pawl are kept separated. When the object is dumped, the device forms an angle with the object due to gravity, and the supporting force generated when the supporting member of the device contacts the ground, by connecting the telescopic rod group and the spring, in addition to the shock absorber, the spine is automatically The claw is inserted into the ratchet, and the ratchet and the pawl are in a state of being embedded, and since the ratchet is fixed on the shaft, the object can be prevented from falling over. If it is installed in a wheelchair, it can avoid being stuck on the slope and it is convenient to move, such as installing in a box or cabinet, without damaging the wall and the ground, and it is very easy to move.

The invention provides an automatic anti-tip device for a ratchet clutch, which mainly uses a ratchet and pawl clutching manner to prevent an object from falling; if the object is not dumped, the device is always directed to the center of the earth due to gravity, and the ratchet and the spine at this time The claw is in a state of being separated; when the object is dumped, the device forms an angle with the object due to gravity, and the supporting force generated when the supporting member of the device contacts the ground is automatically inserted into the ratchet by connecting the telescopic rod set At this time, the ratchet and the pawl are in an embedded state, and since the ratchet is fixed on the shaft, the object can be prevented from falling over.

In addition to the shock-absorbing and supporting connection of the telescopic rod set, the function of the spring can also make the ratchet and the pawl produce a clutch by the telescopic elastic force. The shaft is fixed at both ends of the shaft, so that the rotating shell is restricted from rotating on the shaft, does not fall out, and there are multiple holes on the outer side of the sleeve for mounting the fixing bracket module, and the fixing bracket module includes a fixing plate and a fixing The element F and the fixing element G mount the automatic anti-tip device of the ratchet clutch on the object by the fixing plate, the fixing element F and the fixing element G.

The telescopic rod set is connected, and the telescopic rod set mainly connects the pawl and the supporting element, and the connecting telescopic rod set can adjust the appropriate height according to the object. The telescopic rod assembly includes: an upper rod element and a lower rod element; the upper rod element and the pawl are fixed by the fixing element B, the upper rod element and the lower rod element are fixed by the fixing element D, and the lower rod element has a plurality of adjustment holes, and the lower rod element has a plurality of adjustment holes, The fixing element D adjusts the height of the connecting telescopic rod set; the lower rod element and the supporting element are fixed by the fixing element E.

The supporting element, the main function of which is the supporting force generated when contacting the ground, and the pawl is inserted into the ratchet by connecting the telescopic rod group to prevent the object from falling over. Depending on the use of the object, it can be a movable support element. When the object is dumped, it will also move with the object. For example, objects such as wheelchairs, carts and electric gates that need to be moved, and fixed support elements, when the object is dumped, it is not Will move, such as things like cabinets and boxes that need to be fixed.
