Summary of the invention

Object of the present invention

In the trolley of Patent Document 1, when loading or unloading cargo from the bed, the fence can be prevented from interfering with loading and unloading by detaching the fence from the bed. However, in such a configuration, a place must be provided for storing the fencing removed from the loading area, which is difficult when loading and unloading in a narrow space. The present patent specification provides a technique with which the loading and unloading of the trolley can be carried out in a narrow space.

Means for solving the task

The trolley disclosed in the present patent specification has a loading area with a storage area and a fence which is provided at an end portion of the loading area. The fence may be movable between a first state in which it is held at a first level with respect to the loading area and a second state in which it is held at a second level that is lower than the first level. An angle of the fencing in relation to the loading area can be essentially the same in the first state and in the second state.

According to the above configuration, by bringing the fence to the first state, the load can be prevented from falling from the loading area when the loading area is loaded, and by bringing the fencing into the second state, the Fencing hinders loading and unloading when the loading area is being loaded or unloaded. In the above embodiment, it is not necessary to remove the fencing from the loading area during loading and unloading, which is why no place is required to put down the fencing removed from the loading area. Since, according to the above configuration, the angle of the fence in relation to the loading area is essentially the same in the first state and in the second state, the required working space can be kept smaller than would be the case if the height of the fence was increased by tilting the fence in In relation to the loading area would be reduced. Thus, according to the above configuration, the loading and unloading of the trolley can be carried out in a narrow space.

Embodiment of the invention

A representative, non-limiting example of the present invention will now be described in detail with reference to the accompanying figures. This detailed description is only intended to provide those skilled in the art with details for carrying out preferred examples of the invention, and is not intended to limit the scope of the present invention. Additional features and inventions disclosed below provide a further improved trolley, a method of manufacture, and a method of use therefor and can therefore be used separately from or together with further features or inventions.

Combinations of the features or steps disclosed below in the detailed description are not specified as absolutely necessary in the broader sense for practicing the present invention, but rather are given specifically to explain representative specific examples of the present invention. The various features of the specific examples given above and below, as well as the various features set forth in the independent claim and the dependent claims, when providing additional and useful embodiments of the present invention need not be in accordance with the specific examples given herein or in the exemplified Order to be combined.

All features listed in the present description and / or the claims are to be understood separately from the configuration of the features listed in the exemplary embodiment and / or in the claims, limited by the disclosure at the time of application and the claimed subject matter as separate and independent disclosure. All information on numerical ranges and groups or amounts are to be understood as a disclosure of embodiments within this information, restricted by the disclosure at the time of application and the claimed subject matter.

In one or more embodiments, the trolley can have a loading area with a storage area and a fence, which is provided on an end section of the loading area. The fence may be movable between a first state in which it is held at a first level with respect to the loading area and a second state in which it is held at a second level that is lower than the first level. An angle of the fencing in relation to the loading area can be essentially the same in the first state and in the second state. For example, the difference between an angle of the fencing in relation to the loading area in the first state and an angle of the fencing in relation to the loading area in the second state can be within a range of ± 3 degrees.

According to the above configuration, by bringing the fence to the first state, the cargo can be prevented from falling off the loading area when the loading area is loaded, and by bringing the fencing to the second state, the Fencing hinders loading and unloading when the loading area is being loaded or unloaded. In the above embodiment, it is not necessary to remove the fencing from the loading area when loading and unloading, which is why no place is required to put down the fencing removed from the loading area. Since, according to the above configuration, the angle of the fencing in relation to the loading area is essentially the same in the first state and in the second state, the required working space can be smaller than would be the case if the height of the fence were reduced by tilting the fence with respect to the loading area. Thus, according to the above configuration, the loading and unloading of the trolley can be carried out in a narrow space.

In one or more embodiments, the fence may be movable between the first state and the second state substantially without changing the angle of the fence with respect to the loading area. For example, the change in the angle of the fence with respect to the loading area when the fence is moved between the first state and the second state can be in a range of +3 degrees.

Compared to an embodiment in which the fence is tilted with respect to the loading area when the fence is moved between the first state and the second state, according to the above embodiment, the fence can be in a confined space between the first state and the second state be moved.

In one or more embodiments, the position of an upper end of the fence in the transport trolley in the second state can be below the storage area.

According to the above configuration, the fence can be prevented from interfering with loading and unloading by bringing the fence to the second state.

In one or more embodiments, a distance between the fencing and the loading area in the first state and in the second state can be essentially the same in the case of the transport trolley when the transport trolley is viewed from above. The difference between the distance between the fencing and the loading area in the first state and the distance between the fencing and the loading area in the second state when viewing the trolley from above can be, for example, in the range of ± 5 mm.

Compared to an embodiment in which the fence in the second state has to be arranged further away from the loading area than in the first state, according to the above embodiment, the loading and unloading of the trolley can be carried out in a smaller space.

In one or more embodiments, when the transport cart is viewed from above in a plan view in the first state and in the second state, there may be a distance between the fence and the loading area of 25 mm or more.

Since, according to the above embodiment, a distance between the fence and the loading area into which the user can insert his hand is ensured both in the first state and in the second state of the fence, the user can grasp the fence more easily.

In one or more embodiments, the dolly may further include a restriction mechanism that restricts movement of the fence between the first state and the second state.

According to the above configuration, the fence can be prevented from accidentally moving between the first state and the second state.

In one or more embodiments, the trolley can also have a securing mechanism that prevents the fencing from being released from the loading area.

According to this configuration, it can be prevented that the fence unintentionally falls from the loading area.

As in 5 shown is the warning button 70 on the side surface of the housing 66 in terms of the control panel 68 provided on the left. The warning button 70 is a button that allows the user to sound a buzzer described below 124 (please refer 13 ) buzzing. The dolly 2 lets the buzzer 124 buzz and generate a warning sound when the user presses the warning sound button 70 actuated. When the dolly 2 except for the buzzer 124 also has a loudspeaker (not shown), the trolley can 2 be designed in such a way that according to the actuation of the warning button 70 a specific melody or sound is output from the loudspeaker by the user.

The operating lever 72 is an element made of plastic. As in 8th shown, the control lever 72 a support section 72a , an operating piece 72b and a sensing piece 72c on. The carrier section 72a , the operating piece 72b and the sensing piece 72c are formed in one piece. The carrier section 72a and the sensing piece 72c are inside the case 66 recorded. The operating piece 72b jumps over an opening 66a on the back surface of the case 66 is formed from the interior of the housing 66 outwards. The carrier section 72a is about an axis of rotation extending in the left-right direction 72d rotatable on the housing 66 stored. Inside the case 66 in the area of the detection piece 72c is an operating switch 78 recorded. When the user has an operation to press the operating piece 72b executes upwards, rotate the actuating piece 72b , the beam section 72a and the sensing piece 72c in one piece around the axis of rotation 72d , and the sensing piece 72c presses, as in 9 shown the power switch 78 . Also inside the case 66 a compression spring (not shown) added, the a moment in a direction of downward movement of the operating piece 72b on the control lever 72 exercises. When the user pushes the actuator 72b lets go, the actuating piece will turn 72b , the beam section 72a and the sensing piece 72c due to the biasing force of the compression spring in one piece around the axis of rotation 72d , and the sensing piece 72c moves away from the power switch 78 , as in 8th shown. In the vicinity of the actuating piece 72b is the opening 66a of the housing 66 through a bellows cover 80 covered. The bellows cover 80 prevents foreign objects from outside the case 66 through the opening 66a inside the case 66 penetration.

The control panel 68 is on the top surface of the case 66 arranged. The warning button 70 is on the side surface of the case 66 arranged. The operating lever 72 is at the rear of the case 66 arranged. With this configuration, the user can while using the gripping section 38 grabs the control panel with your right hand and your right hand fingers 68 who have favourited the warning button 70 and the operating lever 72 serve.

The tail light 74 is on the rear surface of the case 66 below the operating lever 72 intended. The tail light 74 lights up when a right headlight as described below 156 and left headlight 158 are switched on and go out when they are switched off. The tail light 74 serves as a high visibility section on the back of the transport cart 2 . As in 8th shown is inside the case 66 in front of the tail light 74 a taillight board 82 recorded. The taillight board 82 has LEDs (not shown) for illuminating / not illuminating the tail lamp 74 and the like. The tail light 74 can light up / go out, for example, by a flat LED. If there is a backward movement of the trolley 2 comes to a collision with an obstacle behind it, the gripping section collides 38 first on the obstacle since the tail light 74 further forward than the gripping section 38 is arranged, causing damage from impact on the tail light 74 can be prevented.

The brightness of the tail light 74 is, from the point of view of the safety of the user, preferably such that the rear lamp lights up in the dark 74 can be seen from the rear from a distance of 100 m. The color of the tail light 74 lights up, is preferably a red color, especially orange, Red or the like. When using an LED, for example, compliance with the provisions of JISC502 for bicycle rear lights (in particular the provisions on luminosity and / or the color of the light beam of the rear light) is sufficient as the brightness that can be perceived from the rear from a distance of 100 m in the dark .

The design of the transport trolley 2 can also be such that the tail light 74 coupled to the start of the transport trolley 2 lights up. The dolly 2 can the rear light 74 light up or flash. For example, the trolley 2 be designed so that it has the tail light 74 normally lights up, and if an acceleration sensor (not shown) or the like indicates a deceleration state of the transport vehicle 2 detected, he can turn the tail light 74 blink. Alternatively, the transport trolley 2 be designed so that it has the tail light 74 normally does not light up, and if a light sensor (not shown) or the like detects that the surroundings have become dark, it can switch the rear light 74 let shine. An embodiment is also possible in which the motor is driven by means of a vibration sensor (not shown) or the like 150 is detected, and when the surroundings get dark and the engine 150 is powered, the rear light can 74 be made to shine. Alternatively, the transport trolley 2 be designed in such a way that in the event that a remaining charge of a battery pack described below 112 (please refer 14th ) is low and a power supply to the motor 150 , the cargo bed unit 800 and the like has stopped, the power supply to the tail lamp 74 continues.

The dolly 2 can instead of the tail light 74 also a reflective element (not shown) on the rear surface of the housing 66 exhibit. Because the reflective element absorbs and reflects light and thus the area behind the transport trolley 2 when illuminated, it fulfills the function of a section with high visibility. The reflection element can also have a retroreflective element. The reflective element preferably has a performance which, when illuminated by the headlight of a vehicle or the like, enables the reflected light to be recognized in the dark from a distance of 100 m from the rear. The color of the light reflected by the reflection element is preferably a red color, in particular orange, red or the like. It can also be a combination of the rear light 74 and the reflective element can be used to further improve visibility from behind. In this case, the tail light can 74 and the reflective element can be integrally formed.

As in 10 shown is when looking at the car unit 4th in a plan view from behind, a distance D from a center point of the carriage unit 4th in the left-right direction up to a center point of the rear light 74 in the left-right direction 150 mm or more, preferably 200 mm, for example 250 mm. When the distance D is 150 mm or more, the distance between the right handle is 18th and the left handle 20th 300mm or larger, which is wider than the average adult's hip width. When the distance D is 200 mm or more, the distance between the right handle is 18th and the left handle 20th 400mm or larger, which is wider than the average adult's shoulder width. The distance D can be determined in consideration of the stature of the operator based on the shape of the right handle 18th and the left handle 20th based on the average hip width and shoulder width. When the user holds the right handle 18th and the left handle 20th reaches and behind the trolley 2 stands, the tail light is due to this configuration 74 not blocked by the user's body, so the rear light 74 can be seen from a position behind the user. The center of the car unit 4th in the left-right direction can be a position corresponding to the center of the trunk of the user in the left-right direction when the user is holding the right grip 18th and the left handle 20th reaches and behind the trolley 2 for example, a position midway between the center point of the right front wheel 140 in the left-right direction and the center of the left front wheel 142 be in the left-right direction, for example, a position midway between the center of the right rear wheel 238 and the center of the left rear wheel 258 in the left-right direction can be a position at the center of the handle unit 6th in the left-right direction, or may be a position midway between the center point of the gripping section 38 of the right handle 18th in the left-right direction and the center of the gripping section 48 of the left handle 20th be. As long as the tail light 74 located in a position where it can be seen from a position behind the user when the user holds the right grip 18th and the left handle 20th reaches and behind the trolley 2 it can also be in a different position than the switch box 40 on the carriage unit 4th be provided. For example, the rear light 74 on the right channel 22nd or left channel 24 the handle base 16 be provided. Alternatively, the rear light 74 on the canal 36 of the right handle 18th or on the rear end surface of the gripping portion 38 be provided. Alternatively, the rear light 74 on the canal 46 of the left handle 20th or on the rear end surface of the gripping portion 48 be provided. Alternatively, the rear light 74 on a rear wheel frame 225 a rear wheel unit described below 14th at a point in the area of the right Rear wheel 238 or at a point around the left rear wheel 258 be provided. Even if the tail light 74 is provided at such a location, it is preferred that the glow can be perceived from the rear from a distance of 100 m.

As in 8th and 9 shown are in the housing 66 furthermore a first connecting element 84 , a second connector 86 and a dead man's switch 88 recorded. The first connector 84 is moved in a specified direction (see arrows in 8th and 9 ) movable on the housing 66 held. As in 11 shown, the first connecting element 84 a support strut extending essentially in a straight line from the upper end to the lower end 84a , an auxiliary strut 84b extending from an intermediate section of the support strut 84a extends to the right and then curves upwards, and one extends from the lower end of the support strut 84a pin extending to the right 84c on. As in 8th and 9 shown, the support strut extends 84a to the left of the control lever 72 from an upper portion inside the housing 66 to a lower section. The auxiliary strut 84b is formed in a shape in which it is in a moving range of the first connecting member 84 the gripping section arranged above 38 and the operating lever arranged below 72 not disabled. The second connecting element 86 is about an axis of rotation extending in the left-right direction 86a rotatable on the housing 66 held. At the rear end of the second connecting element 86 is an elongated hole 86b educated. The cone 84c of the first connecting element 84 is in the elongated hole 86b of the second connecting element 86 . When the first connector 84 is moved in the direction of displacement, the pin exercises 84c Pressure on the side wall of the elongated hole 86b off by sticking to the side wall of the elongated hole 86b slides, and the second connecting element 86 rotates around the axis of rotation 86a . The dead man's switch 88 is opposite one on the second connecting element 86 formed lead 86c arranged. When the second connector 86 rotates such that the rear end of the second link rotates 86 moved upwards, the projection pushes 86c against the dead man's switch 88 , and when the second connector 86 rotates such that the rear end of the second link rotates 86 moves down, the protrusion moves away 86c from the dead man's switch 88 . The second connecting element 86 is biased in the direction of rotation by a torsion spring, not shown, in order to move the rear end upwards. At the front end of the second connecting element 86 is a cable holder 86d intended. On the front lower section of the case 66 is a dead man's cable 90 introduced. The dead man's cable 90 has an indoor cable 90a and an outdoor cable 90b on that the circumference of the indoor cable 90a covered. The outside cable 90b is attached to the housing 66 held. The inner cable 90a is attached to the cable holder 86d held.

Braking of the right front wheel is in this state 140 and the left front wheel 142 canceled.

When the brake lever 49 of the left handle 20th is pushed up by the user, the inner cable becomes 94a of the brake cable 94 as in 20th shown in relation to the outer cable 94b moved in. This causes the first connecting element to rotate 186 in a direction that is the input arm 186a moved to the right, and the output arm 186b moves to the left, which is why the inner cable 176a of the right brake cable 176 in relation to the external cable 176b is pulled out. At the same time, the second connecting element rotates 188 in a direction in which the input arm is 188a moved to the left, and the output arm 188b moves to the right, removing the inner cable 182a of the left brake cable 182 in relation to the external cable 182b is pulled out. This will be the right front wheel 140 and the left front wheel 142 braked.

Due to an adjustment tolerance between the right front brake 144 and the left front brake 146 and deterioration of the right brake cable 176 and the left brake cable 182 Over time it may happen that the right front brake is applied 144 and the left front brake 146 is different, although the right brake cable 176 and the left brake cable 182 pulled out to the same extent. When the indoor cable 94a of the brake cable 94 in relation to the external cable 94b is drawn in, it can happen, for example, that the right front brake 144 the brake pads in contact with the brake disc 172 but with the left front brake 146 the brake pads are not in contact with the brake disc 178 reach. When the indoor cable 94a of the brake cable 94 in this state in relation to the external cable 94b is drawn in, although the first connecting element rotates 186 no further, but there is the second connecting element 188 turns further, you can also use the brake pads on the left front brake 146 in contact with the brake disc 178 reach. According to the brake compensation 148 of the present embodiment can in this way by the respective rotating operation of the first connecting element 186 and the second connecting element 188 an imbalance in pulling force will be absorbed on the right brake cable 176 and the left brake cable 182 acts, and so the braking force on the right front brake 144 and the braking force on the left front brake 146 be brought into balance.

The brake compensation 148 can also as in 56 be shown designed. In the in 56 The embodiment shown has the brake compensation 148 a middle bracket 184 , a first connecting element 802 and a second connector 804 on. The front end of the first connector 802 and the front end of the second link 804 are about an axis of rotation extending in the up-down direction 806 rotatable on the middle bracket 184 held. The inner cable 182a of the left brake cable 182 is at the rear end of the first connector 802 coupled. The inner cable 176a of the right brake cable 176 is at the rear end of the second connecting element 804 coupled. The outside cable 176b of the right brake cable 176 and the outside cable 182b of the left brake cable 182 are both on the middle bracket 184 fixed. The inner cable 94a of the left brake cable 94 is at the middle area of the first connecting element 802 coupled. The outside cable 94b of the brake cable 94 is at the middle area of the second connecting element 804 coupled. A distance from the axis of rotation 806 to the stop position of the inner cable 94a and a distance from the axis of rotation 806 to the stop position of the inner cable 182a at the first connecting element 802 and a distance from the axis of rotation 806 to the stop position of the outer cable 94b and a distance from the axis of rotation 806 to the stop position of the inner cable 176a at the second connecting element 804 are essentially the same.

The inner cable 182a of the left brake cable 182 is through the first connector 802 in relation to the external cable 182b inserted and the inner cable 176a of the right brake cable 176 through the second connecting element 804 in relation to the external cable 176b pushed in when the brake lever 49 of the left handle 20th is not pushed up by the user. Braking of the right front wheel is in this state 140 and the left front wheel 142 canceled.

When the brake lever 49 of the left handle 20th is pushed up by the user, the inner cable becomes 94a of the brake cable 94 in relation to the external cable 94b moved in. Because of this, the first connecting element 802 turns to the right, the inner cable becomes 182a of the left brake cable 182 in relation to the external cable 182b pulled out. Since at the same time the second connecting element 804 turns to the left, the inner cable becomes 176a of the right brake cable 176 in relation to the external cable 176b pulled out. This will be the right front wheel 140 and the left front wheel 142 braked. Also through the design 56 can in this way by the respective turning process of the first connecting element 802 and the second connecting element 804 an imbalance in pulling force will be absorbed on the right brake cable 176 and the left brake cable 182 acts, and so the braking force on the right front brake 144 and the braking force on the left front brake 146 be brought into balance.

Alternatively, the brake compensation 148 also as in 57 be shown designed. In the in 57 The embodiment shown has the brake compensation 148 a middle bracket 184 , a first connecting element 808 and a second connector 810 on. The first connector 808 is about an axis of rotation extending in the up-down direction 812 rotatable on the middle bracket 184 held. The second connecting element 810 is about an axis of rotation extending in the up-down direction 814 rotatable on the middle bracket 184 held. The inner cable 176a of the right brake cable 176 is at the rear end of the first connector 808 coupled. The inner cable 182a of the left brake cable 182 is at the rear end of the second connecting element 810 coupled. The outside cable 176b of the right brake cable 176 and the outside cable 182b of the left brake cable 182 are both on the middle bracket 184 fixed. The inner cable 94a of the brake cable 94 is at the front end of the first connector 808 coupled. The outside cable 94b of the brake cable 94 is at the front end of the second connector 810 coupled. A distance from the axis of rotation 812 to the stop position of the inner cable 94a and a distance from the axis of rotation 812 to the stop position of the inner cable 176a at the first connecting element 808 and a distance from the axis of rotation 814 to the stop position of the outer cable 94b and a distance from the axis of rotation 814 to the stop position of the inner cable 182a at the second connecting element 810 are essentially the same.

The inner cable 176a of the right brake cable 176 is through the first connector 808 in relation to the external cable 176b inserted and the inner cable 182a of the left brake cable 182 is through the second connecting element 810 in relation to the external cable 182b pushed in when the brake lever 49 of the left handle 20th is not pushed up by the user. Braking of the right front wheel is in this state 140 and the left front wheel 142 canceled.

When the brake lever 49 of the left handle 20th is pushed up by the user, the inner cable becomes 94a of the brake cable 94 in relation to the external cable 94b moved in. This causes the first connecting element to rotate 808 in a direction that moves the front end to the right and the rear end moves to the left, which is why the inner cable 176a of the right brake cable 176 in relation to the external cable 176b is pulled out. At the same time, the second connecting element rotates 810 in a direction in which the front end moves to the left and the rear end moves to the right, thereby creating the inner cable 182a of the left brake cable 182 in relation to the external cable 182b is pulled out. This will be the right front wheel 140 and the left front wheel 142 braked. Also through the design 57 can in this way by the respective turning process of the first connecting element 808 and the second connecting element 810 an imbalance in pulling force will be absorbed on the right brake cable 176 and the left brake cable 182 acts, and so the braking force on the right front brake 144 and the braking force on the left front brake 146 be brought into balance.

The second gear 204 is in relation to the intermediate shaft 202 immovable in the left-right direction and is held in a rotatable manner. The claw coupling 205 is in relation to the second gear 204 movable and is not rotatably held on it. The claw coupling 205 has a right-protruding convex engagement portion 205a that with the concave engaging portion 203a of the first gear 203 can engage, and an engaging groove extending in the circumferential direction on an outer peripheral surface 205b on.

The clutch mechanism 206 has a clutch lever 210 , a carrying bracket 212 , a pole 214 and a voter 216 on. The clutch lever 210 and the carrying bracket 212 are on the outside of the gearbox housing 200 intended. The carrying bracket 212 is by screwing on the gear housing 20th fixed. The clutch lever 210 is around an axis of rotation 210a rotatable on the carrying bracket 212 held. The clutch lever 210 has a cam surface 20b on. The pole 214 extends in the left-right direction and runs out of the interior of the gear housing 200 outward. The pole 214 can be moved in left-right direction on the gearbox housing 200 held. The left end of the pole 214 is opposite the cam surface 210b of the clutch lever 210 arranged. The right end of the pole 214 is up to the voter 216 fixed. The voter 216 engages in an engagement groove 205b the claw coupling 205 a. The pole 214 is by a compression spring, not shown, in relation to the gear housing 200 biased to the left. Hence the left end of the pole is located 214 always on the cam surface 210b of the clutch lever 210 on. The cam surface 210b of the clutch lever 210 is shaped so that the rod 214 moved to the left when the clutch lever 210 in terms of the carrying bracket 212 is tilted (see 21st ), and get the pole 214 moved to the right when the clutch lever 210 in terms of the carrying bracket 212 is raised (see 22nd ).

The differential mechanism 208 has a ring gear 208a , a pinion housing 208b , a pinion shaft 208c , a pinion 208d , a right drive gear 208e and a left drive gear 208f on.

The left drive gear 208f is on the left drive shaft 166 fixed and with the pinion 208d interlocked.

When the clutch lever 210 the clutch mechanism 206 as in 21st is brought into the tilted state, the rod move 214 and the voter 216 to the left, and the convex engagement portion 205a of the Claw coupling 205 moves away from the engaging concave portion 203a of the first gear 203 . Even if the first gear is in this state 203 rotates, the second gear rotates 204 Not. The driving force of the motor shaft 198 is therefore not on the ring gear 208a of the differential mechanism 208 transfer. If there is one of the right drive shaft 160 and the left drive shaft 166 rotates, causes the differential mechanism 208 in this case that the other is from the right drive shaft 160 and the left drive shaft 166 rotates at the same speed in the opposite direction.

When the clutch lever 210 the clutch mechanism 206 as in 22nd shown is raised, the bar will move 214 and the voter 216 to the right, and the convex engagement portion 205a the claw coupling 205 engages the concave engaging portion 203a of the first gear 203 a. When in this state the first gear 203 rotates, the second gear also rotates 204 . The driving force of the motor shaft 198 is therefore via the intermediate shaft 202 on the ring gear 208a of the differential mechanism 208 transfer. In this case, the differential mechanism rotates 208 the right drive shaft 160 and the left drive shaft 166 corresponding to that on the ring gear 208a transmitted driving force

Dead man's brake 154

As in 23 shown, has the left front brake 154 a brake disc 218 and a caliper 220 on. The brake disc 218 is at the right end of the motor shaft 198 of the motor 150 fixed. Although in 23 not shown is the circumference of the brake disc 218 of one on the engine box 196 fixed disc cover 218a (please refer 21st and 22nd ) covered. The caliper 220 is in accordance with the brake disc 218 arranged. The caliper 220 is on the engine box 196 held. With the caliper 220 is that off the right grip 18th extending dead man cables 90 connected. The caliper 220 biases a pair of brake pads by a return spring (not shown) in a direction in which they an outer edge region of the brake disc 218 pinch. When the indoor cable 90a of the dead man's cable 90 in relation to the external cable 90b is pushed out, the brake pads thus clamp the outer area of the brake disc 218 a, creating a frictional force on the brake disc 218 acts and the motor shaft 198 is braked. When the indoor cable 90a of the dead man's cable 90 in relation to the external cable 90b is pulled in, the two brake pads move away from the brake disc against the preload force of the return spring 218 , thereby braking the motor shaft 198 will be annulled. With the dead man's brake 154 As described above, it can be a disc brake or another type of brake, for example a shoe brake or a band brake.

When the right front wheel 140 and the left front wheel 142 due to the driving force of the engine 150 rotate, the motor shaft rotates 198 with high speed and low torque while the right drive shaft 160 and the left drive shaft 166 rotate at low speed and high torque. When the dead man's brake 154 the motor shaft 198 decelerates, the torque required for braking is therefore less than in the case that the right front brake 144 the right front wheel 140 brakes and the left front brake 146 the left front wheel 142 decelerates, which is why the rotation of the right front wheel 140 and the left front wheel 142 can be reliably stopped.

The motor 150 , the gear box 152 and the dead man's brake 154 can also as in 58 and 59 be shown designed. In this embodiment, the right end of the motor shaft jumps 198 not from the engine box 196 outwards. Also on the left end is the motor shaft 198 a brake disc 850 fixed.

In the in 58 and 59 The embodiment shown has the gearbox 152 the gearbox 200 , a coupling shaft 852 , the differential mechanism 208 , a differential locking mechanism 854 and a braking mechanism 856 on. In this embodiment form the brake disc 850 and the braking mechanism 856 the dead man's brake 154 . The coupling shaft 852 extends in a left-right direction and is over bearings 852a , 852b rotatable on the gear housing 200 held. The coupling shaft 852 has a spur gear 852c and a spur gear 852d on. The spur gear 852c is with one on the motor shaft 198 provided spur gear 198c interlocked. The spur gear 852d is with the ring gear 208a of the differential mechanism 208 interlocked.

The differential locking mechanism 854 has a dog clutch 858 and a compression spring 860 on. The claw coupling 858 is in relation to the left drive shaft 166 slidable in the left-right direction and is so on the left drive shaft 166 kept it with the left drive shaft 166 is rotatable in one piece. The claw coupling 858 has a right-protruding convex engagement portion 858a and an engaging groove extending in the circumferential direction on an outer peripheral surface 858b on. In the present embodiment is on the ring gear 208a of the differential mechanism 208 an engaging concave portion 208i with which the convex engaging portion 858a the claw coupling 858 intervenes. The compression spring 860 is in relation to the gear case 200 the claw coupling 858 to the right (i.e. to the ring gear 208a towards) preloaded.

The braking mechanism 856 has a pole 862 , a brake plate 864 and a compression spring 866 on. The pole 862 extends in the left-right direction and runs out of the interior of the gear housing 200 outward. The pole 862 can be moved in left-right direction on the gearbox housing 200 held. To the left end of the pole 862 is the inner cable 90a of the dead man's cable 90 coupled. The outside cable 90b of the dead man's cable 90 is to the gearbox 200 coupled. At the right end of the pole 862 is the brake plate 864 fixed. On the brake plate 864 are a brake shoe 864a which corresponds to the brake disc 850 is arranged and a voter 864b provided with the engagement groove 858b the claw coupling 858 intervenes. The compression spring 866 tensions the brake plate 864 in relation to the gearbox 200 to the right (i.e. to the brake disc 850 down).

When the indoor cable 90a of the dead man's cable 90 as in 59 shown in relation to the outer cable 90b is pushed out move due to the biasing force of the compression spring 866 the pole 82 and the brake plate 864 to the right, and the brake shoe 864a is attached to the brake disc 850 pressed. As a result, a frictional force acts on the brake disc 850 a so that the motor shaft 198 is braked. By being on the brake plate 864 intended voters 864b moved to the right, the dog clutch moves 858 due to the preload force of the compression spring 860 to the right, and the convex engagement portion 858a the claw coupling 858 occurs with the concave engaging portion 208i of the ring gear 208a engaged. In this case, the differential mechanism 208 the ring gear 208a in relation to the left drive shaft 166 fixed, causing the right drive shaft 160 and the left drive shaft 166 turn at the same speed in the same direction. By using the dead man's brake 154 the rotation of the motor shaft 198 is braked and thereby the rotation of the ring gear 208a is braked, the rotation of the right drive shaft is also 160 and the left drive shaft 166 braked.

When the indoor cable 90a of the dead man's cable 90 as in 58 shown in relation to the outer cable 90b is retracted, the rod will move 862 and the brake plate 864 to the left, and the brake shoe 864a moves away from the brake disc 850 . This will slow down the motor shaft 198 canceled. By being on the brake plate 864 intended voters 864b moved to the left, the dog clutch moves 858 to the left, and the convex engagement portion 858a the claw coupling 858 disengages from the engaging concave portion 208i of the ring gear 208a . In this case, the differential mechanism rotates 208 according to the driving force coming from the motor shaft 198 via the coupling shaft 852 on the ring gear 208a is transmitted, the right drive shaft 160 and the left drive shaft 166 .

As described above, the trolley 2 in one or more embodiments, the loading area 302 with the storage area and the end section of the loading area 302 provided right protection 304 (or left guard 306 or front protection 308 ) (Example of fencing). The right protection 304 (or the left guard 306 or the front guard 308 ) is between a first state in which he is in relation to the loading area 302 is maintained at a first height, and is movable to a second state in which it is movable with respect to the loading area 302 is maintained at a second level that is lower than the first level. A corner of right protection 304 (or the left guard 306 or the front guard 308 ) in relation to the loading area 302 is essentially the same in the first state and in the second state. For example, there is a difference between the angle of the right guard 304 (or the left guard 306 or the front guard 308 ) in relation to the loading area 302 in the first state and the angle of the right protection 304 (or the left guard 306 or the front guard 308 ) in relation to the loading area 302 in the second state in a range of ± 3 degrees.

In that, according to the above configuration, the right protection 304 (or the left guard 306 or the front guard 308 ) is brought into the first state, the load may fall from the loading area 302 prevented when the loading area 302 is loaded with cargo, and by the right protection 304 (or the left guard 306 or the front guard 308 ) to the second state brought, can prevent the right protection 304 (or the left guard 306 or the front guard 308 ) obstructs loading and unloading when the loading area is being loaded or unloaded. With the above configuration, it is not necessary to have the right protection 304 (or the left guard 306 or the front guard 308 ) when loading and unloading from the loading area 302 take off, which is why there is no place to put the from the loading area 302 removed right protection 304 (or left guard 306 or front guard 308 ) is required. Since according to the above configuration, the angle of the right guard 304 (or the left guard 306 or the front guard 308 ) in relation to the loading area 302 is essentially the same in the first state and in the second state, the required working space can be kept smaller than would be the case if the level of the right protection 304 (or the left guard 306 or the front guard 308 ) in relation to the loading area 302 would decrease. Thus, according to the above configuration, the loading and unloading of the transport vehicle can 2 be carried out in a confined space.

In one or more embodiments, the right protection 304 (or the left guard 306 or the front guard 308 ) essentially without changing the angle of the right guard 304 (or the left guard 306 or the front guard 308 ) in relation to the loading area 302 be movable between the first state and the second state. For example, with the right protection 304 (or the left guard 306 or the front guard 308 ) a change in the angle of the right guard 304 (or the left guard 306 or the front guard 308 ) in relation to the loading area 302 when moving the right guard 304 (or the left guard 306 or the front guard 308 ) between the first state and the second state in a range of +3 degrees.

Compared to an embodiment in which the right protection 304 (or the left guard 306 or the front guard 308 ) in relation to the loading area 302 is tilted when the right protection 304 (or the left guard 306 or the front guard 308 ) is moved between the first state and the second state, the right protection 304 (or the left guard 306 or the front guard 308 ) are moved in a confined space between the first state and the second state.

In one or more embodiments, the trolley is located 2 the position of an upper end of the right guard 304 (or the left guard 306 or the front guard 308 ) in the second state below the storage area of the loading area 302 .

According to the above configuration, the right protection can be prevented 304 (or the left guard 306 or the front guard 308 ) the loading and unloading hindered by the right protection 304 (or the left guard 306 or the front guard 308 ) is brought into the second state.

In one or more embodiments, the trolley is 2 when looking at the transport trolley 2 in plan view from above the distance between the right guard 304 (or the left guard 306 or the front guard 308 ) and the loading area 302 essentially the same in the first state and in the second state. For example, there is a difference between the distance between the right protection 304 (or the left guard 306 or the front guard 308 ) and the loading area 302 in the first state and the gap between the right protection 304 (or the left guard 306 or the front guard 308 ) and the loading area 302 in the second state when looking at the transport trolley 2 in a top view from above in a range of ± 5 mm.

Compared to an embodiment in which the right protection 304 (or the left guard 306 or the front guard 308 ) in the second state further from the loading area 302 must be arranged remotely than in the first state, the loading and unloading of the transport vehicle can according to the above configuration 2 be carried out in a confined space.

In one or more embodiments, the trolley is located 2 when looking at the transport trolley 2 in plan view from above in the first state and in the second state a distance between the right protection 304 (or the left guard 306 or the front guard 308 ) and the loading area 302 of 25 mm or more.

Since, according to the above configuration, both in the first state and in the second state of the right protection 304 (or the left guard 306 or the front guard 308 ) a distance between the right guard 304 (or the left guard 306 or the front guard 308 ) and the loading area 302 is ensured in which the user can insert his hand, the user can get the right protection 304 (or the left guard 306 or the front guard 308 ) grip more easily.

In one or more embodiments, the trolley 2 also the flange 328d (Example of the restriction mechanism) on the the movement of right protection 304 (or the left guard 306 or the front guard 308 ) between the first state and the second state.

According to the above configuration, the right protection can be prevented from becoming 304 (or the left guard 306 or the front guard 308 ) inadvertently moved between the first state and the second state.

In one or more embodiments, the trolley 2 also the locking screw 304c (Example of the safety mechanism) on the release of the right protection 304 (or the left guard 306 or the front guard 308 ) prevented.

According to this configuration, the right protection can be prevented 304 (or the left guard 306 or the front guard 308 ) unintentionally from the loading area 302 falls down.
