    Folding golf cart
    5 Object of the invention
    As stated in the present specification, the invention relates to a golf cart similar in format to those commonly used during the practice of this sport to carry only the bag of clubs; but with the particularity, in this case, that 10 allows the bag to be transported with the sticks and / or to the player himself. The configuration of this cart allows the player to decide at any time if he drives it up or walks behind
    or ally.
    Additionally, the cart of the invention is an electric golf cart that, in addition to
    15 to be able to transport both the bag and the player, it is small in size and light, manipulable and fully foldable by a single person. Once folded, it can be easily transported in the trunk of any conventional tourism and stored or stored in a domestic closet, or even billed without inconvenience on international or domestic flights.
    Background of the invention
    As is known, golf is a growing sport both in Spain and in all developed or developing countries where the climate allows it to be practiced. A figure
    25 indicative of the huge number of fans of this sport is that, in Spain alone, in March 2014 there were almost 320,000 federated players and 422 fields.
    In recent years the practice of golf has become very popular, so the 80 million players estimated today in the world could become more than 120 in
    30 less than ten years. According to different studies, the main reason for this increase in the number of players is the increase in longevity, associated with good health, which has been achieved in the last fifty years. That is to say more people, for more years they look for ways to maintain their good physical condition and spend time in a pleasant way.
    Precisely, the increase of this type of public with greater potential has been one of the reasons why this sport has so many followers today, a large part of which are therefore of advanced age.
    However, both the elderly and those who suffer from some type of disability or physical limitation, may sometimes encounter the difficulty of the need to travel distances of several kilometers, which limits their practice.
    To facilitate the practice and help resolve these limitations in the state of the art, various solutions have been developed in recent years to transport both the bag of clubs and the player himself.
    They can be classified into two categories:
    a) The first is one in which devices are used to transport only the bag of sticks, such as those known in slang as "electric carts."
    Originally the players carried the bag of sticks on the back hooked in the form of a backpack. To unload the backs and avoid injuries, carts have been developed for years that facilitate the transport of these bags, which can contain up to 14 sticks, an important number of balls and other accessories, which can be between 12 and 18 kg or even more
    At first the carts were pulled or pushed by the player himself; but for some years they have been incorporated with electric motors powered by batteries of sufficient capacity that drive an electric motor connected to a gearbox that transmits the movement to the wheels. In this way the player walks behind or next to the cart orienting his direction manually, but without having to make any physical effort to move.
    These electric carts are built with suitable mechanisms that support the weight of the bag and have the necessary joints to be folded so that they are easily transportable and fit in the trunk of any
    car.
    In other words, a cart for the bag of sticks is a common component of a team of
    golf for a player who practices the sport frequently in different fields.
    5
    Thus, the folding capacity of these "carts" is very important, since their
    functionality is that they can be handled, stored and transported
    easily by the players themselves from one field to another. In addition, due to its
    simple structure and low cost, allows these to be acquired in property, without
    10 Having to resort to your rental in each field.
    b) The second consists of vehicles capable of transporting both the bag of the sticks
    Like the player himself. For example, cars known by the English word
    "buggies ~, tricycles, motorcycles, SegwaysTM or other types of vehicles.
    fifteen
    In many fields of the world and due to its orography, the congestion produced by
    the high number of players and / or the lack of resistance / physical form of the
    same, there are different types of "buggies" that can carry one or two
    players and their bags of clubs.
    twenty
    Thus, for the high percentage of players already in the third age, having
    One of these vehicles is almost a necessity if you want to enjoy the practice of
    this sport without having to walk several kilometers and without slowing down the
    game.
    25
    These vehicles, similar in size to a small utility, are usually however
    owned by the clubs themselves that manage the field and rent them to the
    players for a certain fee, which may be equal to or more important than
    which costs what is known as ~ green fee ", that is what the field charges for the
    30 right to play a game of 9 or 18 holes. This makes your rent more expensive
    notably the practice of this sport and, in addition, you can limit it because in the
    Fields there are normally a lower number of vehicles than players one day.
    It also happens that some players who practice the sport very often decide to buy one and keep it on the field where they are partners or subscribers and play regularly. In addition to the purchase means a considerable initial investment, if the car is owned by the player, the fields charge a relatively significant amount for the parking of the vehicle as if it were the case of a parking space for a car.
    In addition, due to its size, in no case will the player who owns one of these vehicles be able to transport it in a normal car, not even a van, rancher or an all-terrain vehicle, when deciding to go play in another field. This, of course, is an important limitation for its use.
    To solve these problems, different vehicles have appeared in the State of the Art that, on the one hand, seek to transport both the bag of the sticks and the player himself by means of a simple structure and a small size that allows its transfer so that the owner can Use them in different fields.
    Thus, carts of very simple structure and easy folding are known that allow both the sticks and the bag to be transported, for example those shown in W02014 / 059972 or W02012 / 069656. These carts, however, are appropriate for players with a certain physical form, since they must stand up enduring the balance, which is not available to older players, whose reflexes are minor, nor for those with any problem in the lower extremities In addition, the second of them does not seem to be intended to be used as a simple cart that can be guided by the player if he prefers to walk by his side instead of climbing.
    Another known cart, such as the W02008 / 011705, although it allows both to be pushed by the player and that he is seated, nevertheless presents a voluminous structure that suffers from a lack of folding facilities, so it will not be possible to introduce it in the trunk of a conventional tourism or in a domestic closet, nor be handled by a person of a certain age or low physical condition. In addition, as can be seen in the figures, so that the user can dispose of the cart by pushing it, the orientation of the handlebar must be changed, which obviously implies a

    inconvenient if the necessary skill or strength is not available. Finally, said cart also suffers from an important drawback such as the fact that, due to its structure, the bag with the sticks once placed is at a considerable height, which in turn determines that the handlebar is also placed at a considerable height so as not to collide with the sticks, forcing the seat to be high, and at a considerable height for being placed on said bag. This is an inconvenience not only for people of short stature, but especially for people who because of their advanced age do not have sufficient ability to get on or off the saddle if they cannot conveniently support their feet on the floor when performing this movement.
    On the other hand, there are other carts or vehicles that, although they allow the player to be comfortably transported, have the housing for the bag of the sticks in their front part, which makes vision difficult and compromises the stability of the set, both on and off. An example of these devices can be seen in ES2159474. In addition, the cart described in this document suffers from a lack of folding that allows it to be handled and stored comfortably. Specifically, it only allows the handlebar to be folded down on the platform, but not to reduce the length of said platform, so that the horizontal dimension of the cart remains unchanged, that is, without folding capacity.
    Another example, shown in CN201227509, describes a simple device, which, although it considerably facilitates its folding, requires to disassemble its vertical column, remove the seat and wheels, which obviously implies a serious inconvenience in the face of user comfort , which do not want to waste play time in the assembly and disassembly of it. In this document, a folding option is shown without dismantling the wheels, but nevertheless it is detrimental to the occupied space. Even so, it is still necessary to fold its vertical column several times and disassemble the seat. In addition, as in the case described above, it has the disadvantage that once the bag is placed with the sticks the saddle is located at an uncomfortable height for certain types of players. Finally, the handlebar structure makes it difficult to handle it when the user is seated, forcing him to adopt a forced and inclined posture towards the bag, also hindered by the obstacle posed by the sticks when protruding from said bag.
    Thus, all these solutions suffer from any of the aforementioned problems, especially the fact that they are not suitable for older people to enjoy the practice of golf, either because they are not adequate during their transfer through the field, because the seat height is excessive , for having a structure that makes them difficult to fold, for having an excessive weight or volume that makes them difficult to manipulate by a single person, for not allowing their guidance as if it were a cart without having to get on it or that the step from one modality to another it is carried out through an uncomfortable maneuver or to be transported and / or because it cannot be transported in the trunk of a conventional tourism or stored in a domestic closet.
    In other words, all the solutions proposed so far suffer from any of the aforementioned problems because none of them solve them in their entirety. These problems especially affect older people, preventing them from carrying out the practice of complete golf, that is, taking the tour with the least possible number of strokes and enjoying a walk in a pleasant and outdoor environment.
    The applicant himself owns the ES2411835 patent that collects a multifunctional cart whose novelty is that it provides a solution to some of the disadvantages described above and, although it achieves a great deal because it allows all the functionalities sought, it does not yet have a structure that, being sufficiently robust, allows a folding such that an elderly person can do it just effortlessly and in a minimum number of operations.
    In addition, the structure of the handlebar, although it is fixed both when used as a cart and when the user climbs on top, which is an advantage for the user since it does not need to make modifications every time it alternates between the two modes of use On the other hand, it is difficult to drive it in the case of handling it sitting down, forcing it to stretch the arms to reach said handlebar and to adopt a forced and inclined posture towards the bag, also hindered by the obstacle posed by the sticks when protruding from said bag.
    That is to say, the comfort of not having to carry out any transformation or modification operation in the cart when changing the way of use, sitting or walking, is detrimental to its maneuverability or maneuverability when the sitting position is adopted, or which is the same, the use of the sitting cart is penalized for the benefit of its use when the user walks next to it.
    Description of the invention
    The folding cart of the present invention solves all the problems of the state of the art mentioned above, which is why it is presented as the ideal means of transport during the practice of golf, especially for users of advanced age or reduced mobility who want to walk according to their capacity, although not exclusive of them.
    Specifically, the present invention relates to a folding and electric golf cart that simultaneously has the following functionalities:
    • Suitable for transporting the bag independently and comfortably while the player
    He directs the cart by walking to his side or behind.
    • Suitable for the player, when he decides, sits on it and is transported at the same time as the bag, being able to direct it without having to stop the movement.
    • It is manipulable by a single person, even of advanced age or low physical condition, who can fold and unfold it without help and lift it off the ground comfortably thanks to the features and means incorporated to facilitate said folding and unfolding, as well as its reduced weight and structure .
    • It is fully foldable to be reduced to a size small enough to be introduced into the trunk of a conventional car and, if desired, store it at home, for example in a small closet.
    Thus, thanks to these characteristics, the folding cart of the present invention is presented as the solution to the problems posed by the state of the art, while allowing the player to decide when he wants to walk and when to be transported with his bag and, At the end of the tour, take it home and store it in a domestic closet.
    Specifically, the cart of the invention comprises:
    A frame;At least one pair of driving wheels;At least one pair of spin-free wheels mounted on said frameAt least one pair of electric motors arranged in such a way that each of themcommand one of the driving wheels;At least one rechargeable battery to power the electric motors and the rest of thecart electronics;A saddle or seat so that the user can move sitting on it;A handlebar to control the cart when the cart is driven by the userwhile walking;A first removable control element for handling the cart when the userhe is sitting on him; YA second control element integrated in the handlebar for trolley controlwhen it is directed by the user while walking.
    Wherein the frame in turn comprises in its lower part folding means to fold on itself, located so that the user of the cart only has to pull the frame slightly up to achieve folding, thereby causing the driving wheels they roll towards the wheels free of rotation or vice versa and thus avoiding having to lift the entire structure in suspense.
    In addition, to achieve a total folding of the frame on itself, the folding means are located not in the midpoint of the imaginary line that joins the axes, also imaginary, of both pairs of wheels, driving and free of rotation, but displaced towards one of said axles so that when the frame is folded the pairs of wheels are not facing each other, but that one pair of wheels is positioned next to the other, avoiding its coincidence and therefore a greater volume of the structure being the wheels of considerable size.
    Specifically, being a pair of wheels free of rotation, they can be arranged transversely to the driving wheels, flush with them and without protruding outwards with respect to them, forming a very compact assembly.
    In this way, a folding is achieved that allows the cart frame to be reduced both in length and in height and width and, on the other, that said folding operation is carried out comfortably, with hardly any effort, as much or more as the unfolding operation.
    On the other hand, both the seat and the handlebar are foldable on the frame itself, thereby contributing to the compaction of the assembly in the non-operative or folding position.
    Likewise, an essential aspect of the invention is the fact that once the user has fully deployed the cart, adjusting it to their measurements and preferences, it will not be necessary to make any further adjustments, so that user can alternate the way of use of the same, that is, mounted on it or driving it without any effort while walking, without the need to perform any additional adjustment maneuver or change position of any element.
    This, evidently, supposes a differentiating advantage with respect to the known state of the art, where, as already seen, those few carts that allow the user to both walk and sit on it, need to adapt some element thereof depending on the modality. chosen by the user, which clearly supposes an inconvenience when practicing this sport, which suffers continuous interruptions, in addition to the inherent discomfort or difficulty of making such changes or, in the known case where it is allowed to drive it sitting on it or walking to the side without making changes, the discomfort with which the user is at the time of driving the cart in a sitting position using the same handlebar as to stand. These facts, in the end, make users choose to drive the cart all the way in the same way to avoid such inconveniences.
    This essential aspect of the invention is made possible by the fact that the user has different control elements for each of the ways of handling the cart. As mentioned, a first removable control element for handling the cart in a sitting position and a second control element integrated in the handlebar for control when
    He leads walking.
    Of these two control elements, the first also contributes especially to the positive and innovative aspects of the invention, that is, to the reduced volume of the assembly 5 in the folded position and to the versatility and comfort in its handling, thanks to its removable character, which allows double functionality:
    that can be stored separately, without risk of breakage or deterioration when the cart is collected for storage or transport and, on the other hand
    10 that can be held on the bag of sticks thanks to the fastening means it has, so that the handling of the cart will be very comfortable for the user.
    This also allows that, contrary to the state of the art, the user does not
    15 need to extend their arms to reach beyond the mouth of the bag in order to reach a handlebar. Thus, being able to hold the first control element on said bag of sticks, the second control element, integrated in the handlebar, can be used, exclusively for when the user directs the cart walking, which avoids operations of transformation of the same when alternating between
    20 ride on him or direct him walking.
    Finally, since the structure is formed of a resistant but lightweight material and that the structure of the frame is formed by a suitable structural profile such as a hollow tubular body, the weight of the assembly is not a problem, even for people already
    25 older or with physical problems of any kind.

    Preferred Embodiment of the Invention
    In view of the aforementioned figures, and in accordance with the numbering adopted, an example of a preferred embodiment of the invention can be observed therein, which comprises the parts and elements indicated and described in detail below.
    Specifically, as can be seen in Figures 1 to 6b, the folding golf cart of the invention comprises:
    A frame (1);

    At least one pair of driving wheels (2);At least one pair of free rotation wheels (3) mounted on said frame (1);At least one pair of electric motors (not shown) arranged in such a waythat each of them commands one of the driving wheels;At least one rechargeable battery (4) to power the electric motors and the restof cart electronics;A saddle or seat (5) so that the user can move sitting on it;A handlebar (6) for cart control when directed by the user whilewalksA first removable control element (7) for handling the cart when theuser is sitting on it; YA second control element (8) integrated in the handlebar (6) for the control of thecart when directed by the user while walking.
    On the other hand, as seen in the figures, especially in figures 5, 6a and 6b, the frame in turn comprises in its lower part folding means (9) for folding on itself, positioned so that the user of the The cart only has to pull the frame (1) slightly upwards to achieve folding, thereby causing the driving wheels to roll towards the free wheels of rotation or vice versa and thus avoiding having to lift the entire structure in a suspense. This arrangement also has the advantage that when the cart is in its operational phase, that is, mounted and transporting the bag (17) with the sticks and / or to the user, as shown in figures 1 and 1 b, the weight of these contributes to the rigidity of the assembly, guaranteeing even more that the folding is not done accidentally.
    According to the embodiment shown, said folding means (9) are formed by temporary retention means which, for example, may consist of one or more ratchets (10) which, in cooperation with a spring (11) or the like, allow on the one hand, ensure the union between the two parts of the frame (1) to prevent accidental opening and, on the other, release said joint so that both parts tilt thanks to hinges (12) during the folding operation.
    In addition, to achieve a total folding of the frame on itself, minimizing

    the space it occupies in its non-operative phase, the folding means (9) are located not in the midpoint of the imaginary line that joins the axes, also imaginary, of both pairs of wheels, driving (2) and free of rotation (3), but displaced towards one of said axes. In this way, when the frame is folded, the pairs of wheels are not facing each other but rather that one pair of wheels is positioned next to the other, avoiding their coincidence and therefore a greater volume of the structure as the wheels are of considerable size.
    Specifically, according to the embodiment shown in Figure 4, the folding means (9) are located closer to the imaginary axis that joins the pair of driving wheels (2) than to the imaginary axis that would join the free wheels of rotation (3). Thus, as can be seen in Figure 5, when the carriage is folded, the pair of free wheels (3) is located next to the pair of driving wheels (3), without coinciding with them, that is, placing some following the others, which contributes to reducing the vertical dimension of the cart as shown in said figure 5. In addition, according to said figure 5, the horizontal dimensions of the folded cart, ie the length and width, are also reduced due to the fact that the pair of free-wheeling wheels (3) are arranged transversely to the driving wheels, flush with them and without protruding outwards with respect to them, forming an even more compact assembly.
    In addition, the possibility of placing the freewheels (3) transversely with respect to the driving wheels (2) prevents the distance between the wheels or pairs of driving wheels
    (2) it does not have to be substantially greater than the distance between the wheels or pairs of free turning wheels (3) or vice versa, so that when the frame (1) is bent, some are located inside and others in the exterior, which is detrimental to the width of the assembly, as is understood by also observing Figure 5. In other words, thanks to the fact that in the invention the freewheel wheels (3) adopt a transverse arrangement with respect to the driving wheels (2), it is avoided that the former have to be mounted on an axis of dimensions significantly larger than the axis of the latter, or vice versa, so that when the frame (1) bends both pairs of wheels do not intersect and some are located outside the others, which increases the width of the cart once folded.
    On the other hand, the fact that both the seat (5) and the handlebar (6) are foldable also contribute to the compaction of the trolley assembly in its folded non-operative position.
    on the frame itself (1).
    More specifically, and as can be seen in Figures 4 and 5, the seat (5) is mounted on an inverted U-shaped support bar (13) such that its two lateral branches (14) are attached to the frame articulated by hinged portions such as those shown in said figures or by any other conventional means. On the other hand, said lateral branches (14) have two telescopic sections so that the height at which the seat is placed can adapt to different users or circumstances.
    On the other hand, in said figures the characteristic that the seat (5) is articulated on the support bar (13) is also referenced so that in the folded position, when said support bar (13) is lowered on the frame (1), the seat (5) itself is not positioned perpendicular to said frame
    (1) or sticking out of it, but can also fold over it.
    Another important aspect of the invention derives from the fact that the support bar (13) of the seat (5) has an inverted U-shape and, more specifically, that the space between both lateral branches (14) of the U is the largest possible, with the only limitation of the width of the axle (19) of the driving wheels (2) on which they rest, axle (19) that as will be seen later will house the pair of electric motors (not shown) arranged in such a way that each of them commands one of the driving wheels.
    Thus, this space between the lateral branches (14) is important because it will be occupied by the lower end of the bag (17) with the sticks, which will allow said bag on one side to be retained without the need for additional means and, on the other, that it can adopt a semi-lying position, even crossing said space between
    lateral branches (14) as seen in figure 3, reaching a low elevation just below the seat, which in turn eliminates the problem of having to position the seat (5) at a considerable height, uncomfortable or even unfeasible for people who because of their advanced age do not have sufficient ability to get on or off the saddle if they cannot conveniently support their feet on the floor when making that movement.
    In the case of the handlebar (6), it also contributes to the compaction of the trolley assembly in its folded position because it is foldable. Specifically, as can be seen in Figures 2, 4 and 5, where the handlebar (6) is attached to the frame (1) through a column (15), said column (15) being foldable or collapsible on the frame (1).
    More specifically, according to said figures, the column (15) joins at its lower end to the frame (1) in a collapsible manner, preferably in confluence with the imaginary axis that joins the free wheels of rotation (3), said column (15) presenting ) at its upper end an arc-shaped termination (16) intended to serve as a support and coupling for the bag
    (17) with golf clubs. For fixing between them, bag (17) and arch (16), the latter has an adjustable connecting element (18) such as a tape, strap or the like.
    On the other hand, the joint between the handlebar (6) and said column (15) is also articulated so that not only the latter can be folded or folded on the frame, but also the handlebar (6) itself, which also It comprises at least one telescopic section to be able to set its length according to the user's measurements or tastes.
    For all this, an optimal folding is achieved that allows the cart frame to be reduced to half its length, specifically, and according to a possible embodiment, it is achieved that a cart suitable for transporting a conventional bag (17) can be circumscribed in a cube of 0.70 x 0.70 x 0.50 meters, that is, occupying a volume of 0.245 m 3, transportable in the trunk of a conventional and susceptible vehicle and can also be stored in a small closet.
    In addition, as can be seen in the figures, especially in 3 and 4, the free end of the handlebar (6) comprises a handle (20) to facilitate its grip, as well as, integrated therein, the second element of control (8) for cart control when directed by the user while walking.
    This second control element (8), which may be constituted by, for example, a button, button, actuator, lever, trigger, etc. it is electrically connected in the example of the invention through cables (21) that run inside said handlebar (6), as well as inside the column (15) and the frame itself (1) until reaching the connections Box
    (22), located, for example, in the section of the frame closest to the driving wheels (2).
    Thus, as stated above, once the user has fully deployed the cart, adjusting it to their measurements and preferences, it will not be necessary to make any 5 more adjustments, so that they can alternate the way of using it, that is to say mounted on it
    or by pushing it while walking, without the need to perform any additional adjustment maneuver or to reposition any element.
    Likewise, as already stated, the user has a first control element (7)
    10 removable for handling the cart in a sitting position, which as can be seen in the figures, especially in numbers 1 a, 1 b, 2 and 3, is likely to be held on the bag (17) of sticks through fastening means (23) that allow the user to fix or securely hold said control element (7) to the bag in the position he deems most comfortable.
    15 Thus, said first control element (7) will be easily assembled and disassembled from the bag (17), being able to be fixed to it during the entire course of the game, without the need to move it each time the user changes the use mode of the cart.
    20 This first control element (7) also comprises a joystick or similar mechanism (24) with which the user can control both the speed and the direction of the trolley, that is, forward, reverse, left and right turns. . Specifically, as already said, the cart of the invention has at least one pair of electric motors so that each of them commands one of the driving wheels (2). These engines
    25 electrical units are housed within the hollow tubular structure that forms the frame (1), specifically, each one is directly attached to each axis of rotation of the driving wheels (2), within the axle (19) of the wheels motor (2).
    Thus, more specifically, commanding each of these electric motors separately the
    30 users will be able to print more or less speed on each wheel, which will allow turning the cart in one direction or another. If both engines are driven at the same speed the cart will follow a straight line and, if disconnected, the cart will be braked.
    Said motors are driven by charging one or more rechargeable batteries (4) located, according to a possible embodiment, under the bag (17) in the section of the frame (1) closest to the free rotation wheels (3) . However, said rechargeable battery (4) will be fixed to the frame (1) removably by any conventional method so that the
    The same can be easily removed both when the cart is folded and whenIf your cargo is necessary, it must be repaired or checked, replaced by a new one, etc.
    On the other hand, the first control element (7) comprises a speed selector (26) for the user to choose the one that is most convenient or appropriate, as well as a
    10 on / off switch (25) so that it can be turned off and avoid an involuntary operation, off position in which the use of the second control element (8) is also enabled.
    Thus, while the user is using the cart in the mode in which he sits on it,
    15 with the first control element (7) activated, the second control element (8) will remain disabled. Once said user decides to change to the mode of directing the cart on foot, it will place the switch (25) in the off position, avoiding involuntary movements that can cause it to fall and enabling the handling of the cart from the second control element (8 ), integrated in the handlebar (6).
    Additionally, in order to make the cart structure as versatile as possible, the frame
    (1) It is divided into three fundamental parts, joined together by non-definitive removable means, that is, not welded, in order to be able to separate them when required for maintenance or replacement.
