专利说明:

The safety device in an ioke-burning state. in the spacer means a strap is arranged which at its other end is attached to the one in front of the pram.
For example, if this person should fall or if the carriage rolls uncontrollably down a slope, the person will pull on the strap, which results in the spacer being released from the safety device and the collar member falling down and activating the brake.
In the solutions described above, a safety device for braking the pram is activated when a user acts on a locking member in the form of a clamp and a spacer member, respectively, with a sufficiently large force.
SUMMARY OF THE INVENTION In view of the above, it is an object of the present invention to provide an improved safety net arrangement for a device such as a pram, wheelchair or the like.
More specifically, a safety arrangement is provided for a device such as a pram or wheelchair, comprising an actuator comprising a first part and a second part, the first part being movable relative to the second part between a first position and a second position. The leveling means is arranged in the first position of the first part to actuate a braking arrangement so that it is in a braking state, the actuating means in the second position of the first part being arranged to actuate the braking arrangement so that it is in a non-braking state. The first dough is arranged to take the first ownership in the absence of external influences.
The security arrangement further comprises a locking means which is releasably fixable in the upper means for locking the first part in the second position, the locking means being arranged to cease said locking of the first part in the second position upon application of a predetermined force effect. The first part is rotatable relative to the second part about a geometric axis for movement between the first and the second position. the retaining means comprises a retaining means which upon releasably fixing the locking means in the operating means is arranged to couple the locking means to the operating means, the retaining means upon application of said predetermined force force being arranged to maintain the locking means coupling to the operating means and detach the locking means from the operating means. 10 15 20 25 30 35 3 By applying a predetermined force influence is meant actuation of the locking means by a force exceeding a predetermined threshold value ooh in a predetermined direction.
An advantage of the present invention is that the locking means ceases to read the first part in the second position when applying a predetermined force effect. A person, hereinafter referred to as the driver, in front of the device, such as a pram or wheelchair, hereinafter also referred to as a pram, can be made to actuate the locking means with a force if the driver falls, stumbles, loses control of the pram on a hill or stairs, etc., by coupling by the driver to the reading means with a tape or the like. As a result, the first part returns to the first position in which the actuator acts on the braking arrangement so that it assumes its braking position. A driver who loses control of a trolley with the safety arrangement according to the invention acts on the locking means with a predetermined force effect by, for example, falling, tripping or the trolley pulling away in a downhill or down stairs. When the locking means is affected by a predetermined force influence, the reading of the first part in the second position ceases and the first part assumes its first position instead. in this first position the actuator acts on the braking arrangement so that it assumes its braking position. The trolley will thus be braked. This prevents the trolley from rolling away in a situation where the driver no longer has control over the trolley. For example, if the driver falls on a steep descent, the carriage will not continue to roll away but will be braked by the safety arrangement. In a situation where the driver puts the carriage away in the belief that the carriage will stand still, but because the ground slopes begin to roll, the safety arrangement will slow down the carriage and prevent its movement.
Another advantage of the security arrangement is that it offers extra security. In the event that the safety net arrangement has been exposed to influences such as breakdowns, wear or manufacturing defects which cause the first part not to reach its first position, the driver will not be released from the vehicle.
The retaining means maintains the coupling between the locking means and the operating means until the first part has assumed its first position. When the first part has assumed its first position, in which the braking arrangement is in its braking condition, the locking means is detached from the retaining means. As a result, the driver is not released from the safety arrangement until the brother arrangement brakes the carriage. In the event that the first part does not assume its first position, the driver will still be coupled to the carriage and thus have the opportunity to stop the carriage. This prevents a situation where the safety arrangement does not activate the brakes at the same time as the driver completely distorts the control rail over the carriage.
A further advantage is that the safety arrangement has a simple construction comprising few days, which is advantageous from a manufacturing and cost point of view. Furthermore, the safety arrangement is easy to retrofit to a trolley that lacks any safety arrangement.
The second dough may comprise a section which is adjacent to the radius outside the first dough. The locking means can thus be movable through said section and into contact with the first part for removable fixation in the upper means. The second part thus controls the locking means for engaging the operating means.
The locking means may be arranged to engage the first part for locking the first part in the second position.
The retaining means may comprise a projection arranged to engage with the locking means. The protrusion can engage with a recess in the locking member.
The retaining means can be resilient. This allows the locking means to be brought out of its engagement with the upper means, for example by the driver pulling on the locking means, so that the locking of the first part can cease. At the same time, the coupling of the retaining member with the locking member is maintained.
The retaining means may be arranged for controlling the locking means for locking the first part in the second stroke. Thus, it is sufficient for the driver to insert the locking means into the operating means so that the retaining means engages with the locking means. The retaining means then guides the locking means into engagement with the first part.
The first part may comprise a kiaok arranged to engage the locking means for locking the first part in the second position. The interaction of the locking member with the kayak locks the first part in the second position by preventing rotation of the first part.
The locking means may comprise a pin which is arranged to engage with a recess in the operating means for locking the first part in the second position.
The driver can be coupled to the pin by means of a strap so that when the user pulls on the pin, the locking of the first part in the second position ceases. The retaining means may be provided by a groove defined by the first and the second part. As long as the locking means is inserted in the groove, the engagement of the locking member with the upper member is maintained.
When applying said predetermined force influence, the pin can be arranged to cease its engagement with the socket in the ninth upper member.
The safety net arrangement may further comprise a strap arranged to be connected to the locking means and the driver of the device. The driver may, for example, have the strap fastened around the wrist or to the belt. If the driver is to lose control of the pram, the driver affects the strap, with the result that the locking member is automatically pulled out of its engagement with the first part.
The locking means may be insertable into the upper means in the radial direction.
Said predetermined force influence may be directed in radial direction away from the actuator and the magnitude of which may exceed a predetermined threshold value.
One of the first and the second part may comprise a handle part which is rotatable about said geometric axis! for bringing the actuator to the second position of the first die. The take-up dough facilitates the rotation of the first dough to its second position.
The safety arrangement may further comprise a wire connected to the actuator and the brake arrangement. The air upper means can be actuated by a spring force to cause the first die in the absence of external influence to assume the first property.
According to another aspect of the invention there is provided a stroller comprising a safety arrangement. The advantages described above are also applicable to this aspect of the invention.

Below, embodiments of a safety net arrangement in accordance with the present invention will be described in connection with use on a pram 2. Figure 1 schematically shows a chassis for a pram 2 with a safety arrangement 1 according to a first embodiment. The pram 2 shown has four enjoyable islands, but can also have three or a different number of wheels. The safety arrangement i comprises an operating member 10 and a locking member 3. The overhead member 10 is mounted on a nine-membered part 4 of the pram 2. The operating member iQ is suitably located so that it is easy to reach for the driver. By a driver is meant in the following a person who drives the pram, the roller coaster or a similar device provided with the safety arrangement 1. A strap 6 'is connected to the locking member 3.
The driver can be coupled to the strap 6. For example, the strap d can be sutured with an eye which the driver pulls around the wrist. Alternatively, a hook may be provided in the free end of the belt 6. The hook can be attached to the driver, for example in the belt.
The pram 2 is provided with a brake arrangement 8. Between the actuator 10 and the brake arrangement 8 a wire 7 is arranged. In the embodiment shown, the brake arrangement 8 comprises two brake elements 8. a brake element 8 at one rear wheel 5, and a brake element 8 at the other rear wheel 5. Those skilled in the art will appreciate that the invention can be realized with a brake element, and that the brake element may alternatively be arranged another hjui, for example at a front hjui. Each brake element consists in the example shown of a pin 9 which is pushed into the wheel 5 between its spokes to prevent rotation of the wheel 5 during braking. The person skilled in the art realizes that braking can be achieved in a variety of ways, for example with brake kiosks. or with a magnetic brake.
Alternatively, instead of the wire f, the braking arrangement 8 can be controlled by means of electrical transmission of a signal.
The actuator 1G can take two trains, one actuator in the actuator 1G actuates the well locking arrangement 8 so that it is in a braking state, and another actuator in the actuator actuator 10 actuates the brake arrangement 8 so that it is in a non-humming state. in the absence of external influence, the actuator 10 strives to assume the first property, i.e. The position in which the well arrangement 8 brakes the pram 2. Now with reference to Figures 1 and 2, a first embodiment of the safety arrangement 1 will be described in more detail.
The upper member 10 of the safety arrangement 1 comprises a first part 11 in the form of a handle and a second part 12 in the form of a seat for the base of the handle. The first part 11 is movable relative to the second part 12 with a first and a second position. More specifically, the first part 11 is rotatable relative to the second part 12 about a geometric axis for movement between the first and the second ones. The ivian upper means 1G actuates the first part of the first part of the brake arrangement 8 via said wire 7 (ei shown in figure 2) so that it is in a braking state. In the second position of the first part, the actuator 1D acts on the brake arrangement 8 so that it is in a non-braking state. The first dough 11 strives to assume the first position in the absence of external influences. For example, the actuator 10 may be spring-loaded so that the first part tends to take the first step. 2G 25 30 35 8 In the embodiment shown, the second part 12 has a section which is located radially outside the first part. The second part 12 thus at least partially encloses the first part 11.
The first dough 11 is further provided with a handle part 13.
The handle part 13 extends radially from the first part 11 through an opening in the section of the second target 12. The landing day 13 is arranged to facilitate the rotation of the first day 11 from the first position to the second position. The person skilled in the art realizes that the handle part can be designed in many different ways.
For example, the handle dough may be in the form of a knob.
The first part 11 further comprises a lug 14, the function of which will be described below. The first part 11 comprises in the embodiment shown a retaining member 15. in the embodiment shown the retaining means 15 is in the form of a projection 16. The projection 16 extends in the circumferential direction but may have a different radius than the first part 11.
The protrusion 16 is resilient, for example by removing material from the protrusion.
The second part 12 is provided with a socket 1 through which the locking means 3 can be inserted into the operating means 10. The second part 12 can further be provided but a fastening means 19 for mounting the operating means 10 on the pram 2.
The reading means 3 is provided with a recess 18. The recess 18 is intended to receive the milling means 15 when the reading means 3 is inserted into the operating means 10. At one end of the locking means 3 a strap 6 is fastened, which strap 6 is intended to be fastened to the driver. The other end of the locking member 3 is intended to engage with the kiaoken 14 nos the first part 11 when the locking member 3 is inserted into the operating member 10. in Figures 1 and 2 the operating member 10 is in its first position, in which the operating member 10 acts on the brake arrangement 8 so that it is in burning condition. Thus, the pram 2 is braked. in Fig. 3, to which reference is now made, the displacement of the first part 11 is started by rotation from the first position to the second position.
The driver will now move the pram forward and must thereby release the brake arrangement 8. The driver grips the handle part 13 and turns the first di 11 of the actuator 10 towards the second position, the driver must then overcome the force which causes the first part 11 to strive to assume the first position. The locking member 3 can be inserted into the operating member 1G, for example in a radial direction. Before or in connection with the movement starting by rotation, the locking member 3 is inserted into the upper member 10, through the recess 17 nos the second part 12. The upper member 10 may also be provided with guide elements, for example in the form of lugs, for guiding the locking member 3 in the right direction into the operating means 10. When the rotating movement is started, the first part 11 comes to a position in which the retaining means 15 engages with the socket 18 in the locking means 3. In case the retaining means 15 is a projection 16 arranged on the first part 11, the projection is inserted into the recess 18 reading means 3. In one embodiment, the projection 16 is designed so that the rotational movement causes the projection 16 to guide the locking means 3 further towards the center of the first part 11 for engagement with the first part 11.
Upon further rotation of the first part 11 towards the second position, the resilient retaining means 15 will press an end surface of the locking means 3 against a guide surface in the first part 11. Said lug 14 is formed in said guide surface, and when the first part 11 has reached the second position, the end surface of the locking member 3 has passed said lug 14, which is shown in figure 4. In this second position the engagement of the locking member 3 with the claw 14 counteracts the striving of the first die 11 to assume the first position. The locking means 3 thus locks the first part 11 in the second position in which the brake arrangement 8 assumes its non-braking position. Thus, the pram 2 can be rolled freely without the driver having to pour in the handle part 13 to release the brake arrangement 8. Figure 5 shows a situation where the driver acts on the locking member 3 with a predetermined force, for example by losing control of the pram 2 and thereby influencing the strap 6 which connects the driver to the locking member 3. Examples of such situations may be that the driver stumbles and falls, that the driver in a steep descent or in stairs does not have the strength to pour against the pesky-leaning force, or when the driver puts the pram away in the belief that the pram is standing still but that the stroller nevertheless starts to roll. In this position the driver acts on the locking means 3 with a force exceeding a predetermined threshold value in a direction away from the operating means 10. A driver who falls, for example, pulls the locking means 3 out of the locking means 3 out of his reading position. The locking member 3 thus ceases to engage with the claw 14.
As a result, the locking member 3 ceases with its locking of the first part 11 in the second position. The first part 11 will thus strive to assume its first position since it is no longer affected by any external force. For example, the actuator 1G may be spring-loaded so that the first part tends to assume the first position in the absence of external influence.
As shown in Figure 5, the locking member 3 no longer engages the lug 14.
On the other hand, the retaining member 16 still engages with the socket 18 in the locking member 3. The resilient properties of the retaining member 15 allow the locking member 3 to cease its engagement with the first part 11 while the coupling member 15 is coupled to the locking member 3.
The retaining means 15 maintains its connection with the locking means 3 during the movement of the first part 11 from the second position to the first position.
The retaining means 15 only releases the locking means 3 from the operating means 1G when the first part 11 has assumed the first position.
In the embodiment shown, the projection 16 maintains its engagement with the locking member 3 during the rotational movement until the first part 11 assumes the first position. When the operating member 10 has assumed its first position, the locking member 3 is released from the projection 16. Thereby also the locking member 3 is released from the operating member 10. In this first position, which is shown in figure 6, the operating member 10 influences the braking arrangement 8 so that it assumes its braking condition. When the first part 11 has reached its first position, the pram 2 is thus braked. In the position shown in figure 7, the pram 2 is braked and the driver is free from the pram.
The retaining means 15 acts as an extra security in that the locking means 3 is not detached from the operating means 10 until the first part 11 has reached its first position in which the braking arrangement 8 is in its braking state. In the event that the first part 11 would not reach its first position, the locking means 3 is not released from the operating means 10. Thus, the driver is not released from the pram 2 either and the pram 2 cannot leave uncontrolled.
When the driver then wishes to release the brake arrangement 8 again, the driver again turns the actuator 10 to its second position and inserts the locking means 3 in accordance with what has been previously described above.
Referring to Figures 8-14, a second embodiment of the present invention will be described. As previously described with reference to Figure 1, a safety arrangement 1 is arranged on a chassis of a pram 2 or the like. For example, the safety arrangement 1 can be arranged on a handle part of the pram 2. In the manner described above, the safety arrangement 1 is connected to a braking arrangement in accordance with what is described in connection with the first embodiment. The safety arrangement 1 comprises, as before, a receptacle 10 'and a locking means 30. The receptacle 10' may, for example, be attached to a handle part of the pram by means of a fastening device 19. A brake arrangement 8 arranged on the pram 2 comprises burner elements which affects one or more wheels on the pram. Between the ear arrangement 8 and the actuator 10 'a wire 7 is arranged.
Alternatively, the coupling between the actuator 10 'and the brake arrangement 8 can take place in another way, for instance by means of electrical transmission.
The locking member 30, which is shown in more detail according to 9 and 10, this embodiment comprises a main body 31 and a pin 32 arranged in one end 33 of the locking member. The main body 31 has a circular cross-section. The pin 32 is projecting from the main body 31. The pin 32 is movable between a protruding position, as shown in Figure 9, and a retracted position, as shown in Figure 10, in which the pin 32 is arranged inside the main body 31. The pin 32 is preferably resilient or spring-loaded and strives to assume its protruding position. The pin 32 is connected to a band island extending through the main body 31 and out through the other end of the locking member 30. The strap 6 is intended to connect the driver to the locking means 30. When the user pulls on the strap 6, the driver simultaneously pulls in the pin 32 so that the pin 32 reaches its retracted position. The l-body 31 is further provided with a circumferential recess 34 arranged at a distance from the pin 32. The upper upper member 10 'comprises a first part 21 and a second part 22.
The first part 21 is movable relative to the second part 22 between a first and a second position. More specifically, the first part 21 is rotatable relative to the second part 22 about a geometric axis for movement between the first and the second position. in the first position 21 of the first part 21, the upper member 10 * acts on the braking arrangement 8 so that it is in a braking state. In the second position of the first part 21, the actuator 10 * acts on the brake arrangement 8 so that it is in a non-braking state. The first part 2.1 strives to assume the first position in the absence of external influences. For example, the actuator 10 * may be spring-loaded so that the first part 21 strives to assume the first position.
The first dough 21 is further provided with a handle part 13.
The handle part 13 is arranged to facilitate the rotation of the first part 21 from the first position to the second position. The first and second parts 21, 22 together define a groove 40. The groove 40 has an "f-shaped cross-section. The groove 40 extends circumferentially around a first portion P1 of the circumference of the upper member 10 * (see Figure 13) In a second portion P2 of the circumference of the actuator 101, separated from the first portion, this groove is missing. For example, the circumferential groove 40 may extend around a quarter of the circumference of the actuator 10 'and the groove is missing in a quarter of the actuator 10'. The groove 40 is intended to receive one end 33 of the locking member 30. The circumferential recess 34 of the locking member 30 is intended to be arranged in the outer part of the groove 40 and the outer spirit 33 of the locking member 30 is intended to be arranged in the inner part of the groove 40. geometry is complementary to the geometry of the locking member 30 so that the locking member 30 is prevented from being pulled out of the groove 40 once the locking member 30 is inserted into the groove 40.
The groove 40 thus functions as a retaining member. inside the portion of the groove 40 defined by the first part 21 a recess (not shown) is arranged in the first part 21 in a angular position corresponding to the second position. The shape of the recess is complementary to the shape of the sprint 32.
For example, the socket may be in the form of a non-circular hole if the pin 32 has a circular cross-section. The recess is intended to receive the pin 32 of the locking means 30 for locking the first part 21 in the first position.
Now, the security arrangement in accordance with this second embodiment will be described with reference to Figures 11-14. In Figure 11, to which reference is now made, the first part 21 of the actuator 10 * is in its first position, in which the actuator 10 * acts on the brake arrangement 8 so that it is in its burning state.
In order to enable the pram 2 to move the driver the locking means 30 towards the operating means 10 * and to insert the locking means 30 into the groove 40 of the operating means 10 '. The pin 32 which is arranged in one end 33 of the locking member 30 will then be pressed into the main body 31 of the locking member 30. The driver grips the handle part 13 and turns the first part 21 of the operating member 10 'towards the second layer. The driver must then overcome the force which causes the first part 21 to strive to assume the first position.
In the rotation of the first part 21, clockwise in the embodiment shown, in relation to the second part 22, the locking member 30 will be arranged in the groove 40 formed by the first and the second part 21, 22. The engagement of the locking member 30 with the groove 40 is shown in Figure 12. When the first part 21 has been rotated until the position of the locking member 30 corresponds to the position of the recess on the first part 21, the spring-loaded pin 32 will engage with the recess 32. The engagement of the pin 32 with the recess further prevents rotation of the first part 12 and locks the first part 21 in the second position when the brake arrangement 8 is in its non-braking state. The driver can now roll the pram 2 without having to hollow out the intake manifold 13 to release the well arrangement 8. This is shown in Figure 13.
In a situation where the driver for some reason loses control of the pram 2, for example by falling, the driver acts on the locking means 30 with a predetermined force effect in a direction away from the operating means 10 ". A driver who, for example, fails to actuate the strap and causes the sprint 32 to be pulled out of its engagement with the recess of the first part 21. Thereby the pin 32 ceases with its locking of the first part 21 in the second part. The first part 21 will thus strive to assume its first position. This is because the first part 21 is no longer affected by any external force.
In contrast, the locking means 30 is still arranged in the groove 40 defined by the first and the second part 21, 22, which is shown in figure 13.
The groove 40 thus functions as a grinding pin means for continuing its engagement with the locking means 30 until the first part 21 reaches the first position in which the brake arrangement 8 assumes its braking state. Only when the first part 21 has been turned to its first position does the locking member 30 move freely from the groove and is thereby released from the operating member 10 ". meaning that the locking means 30 moves freely from the groove 40, it is meant that the locking means 30 reaches the portion of the operating means 10 'which is not provided with a groove. This position is shown in figure 14. The driver is now free from the pram 2 and the brake arrangement 8 is in its radiating condition.
The retaining means in the form of the groove 40 acts as an additional safety since the locking means 30 is not released from the groove 40 until the first part 21 has reached the first position in which the brake arrangement 8 is in its braking condition. in that the first part 21 is not to reach its first position, the locking member 30 maintains its engagement with the groove 40 and the locking member 3 is not released from the operating member 102. Thus, the helical driver is not released from the pram 2 and the pram 2 cannot go uncontrolled.
When the driver then wishes to release the ear arrangement 8 again, the driver again turns the actuator 10 ”to its second position and inserts the locking member 30 into the groove in accordance with what has been previously described above.
Above when the safety net arrangement is described in connection with a pram. It will be appreciated that the inventive safety arrangement may also be used for other types of carriages, wheelchairs, walkers, or the like.
The safety net arrangement can also be used for similar purposes on other types of vehicles and machines where it is desirable for the vehicle to be braked if the driver loses control of the vehicle. Examples of such devices are lawnmowers, snowmobiles, personal watercraft, hand tools, work machines, trains, boats, etc. In the embodiment described with reference to Figures 8-14, the second part 22 has a portion where the second part 22 does not enclose the first part 21. In an alternative embodiment, the second part 22 may enclose the first part 21 also in this portion. In that case, the second part 22 has an opening in which the locking means can be inserted for engagement with the operating means and an opening for the handle part 13. Like the previously described embodiment, the first part 21 and the second part 22 do not form a groove in this portion.
Accordingly, several modifications and variations are possible, so that the scope of the invention is thus defined exclusively by the appended claims. For example, it will be appreciated that the first and second portions of the nose actuator may have a different relative position, which may mean that the first portion carrying the handle portion radially encloses the second portion.
