Travel bag for a golf equipment

Abstract

A travel bag for golf equipment. The bag has a rear part provided with a first pair of castors and in the bottom of the rear part a stiffening plate that does not extend to the front part of the bag. Under the travel bag at the other end of the stiffening plate is a second pair of castors so that in the horizontal position of the bag the rear part of the bag is supported by the first and second pairs of castors and the front part of the bag is supported on the ground. The front part of the bag can be pulled off the ground using grab element so that the bag can trail on the first and second pairs of castors behind the user.

Claims

1. A travel bag for golf equipment, comprising a first pair of castors at a rear end under a bottom of the travel bag and a grab element at a front end of the travel bag, wherein the bottom of the travel bag comprises a stiffening plate having opposed front and rear edges, the stiffening plate extending from the rear edge to the front edge at least 50% of a length of the bottom of the travel bag measured from the first pair of castors located at the rear end of the travel bag, and a second pair of castors located under the bottom of the travel bag near the front edge of the stiffening plate, wherein the stiffening plate is disposed in a rear part of the travel bag and does not extend to a front part of the travel bag, the front part of the travel bag without the stiffening plate being configured and dimensioned such that, with the first and second pairs of casters on the ground, the front part of the travel bag can settle down against the ground lower than the rear part of the travel bag and act as a brake to hinder rolling of the casters and, by pulling the grab element at the end of the travel bag, the front part of the travel bag can be lifted off the ground so that the travel bag rests on the ground only on the first and second pairs of castors and can roll on the first and second pairs of castors in the pulling direction.

MODE(S) FOR CARRYING OUT THE INVENTION

(5) The travel bag is manufactured of a flexible material, such as waterproof fabric or any other suitable flexible material, such as plastic-coated fabric, etc.

(6) In addition to the castors 2 at one end of the travel bag 1, an additional pair of castors 5 is provided under the bottom of the travel bag 1 in the extent of approximately 50%-65% of the total length of the travel bag 1 (measured from the rear castors 2) preferably with the same longitudinal direction as the rear castors 2 of the travel bag 1. In other words, in the horizontal position of the travel bag 1 shown on the figures, the rear part 6 of the travel bag 1 comprising the stiffening plate 4 rests on the castors 2 and 5.

(7) In the embodiment shown on FIGS. 1 to 3, the castors of the additional pair of castors 5 are fixed to roll along a straight-line path, i.e. these castors cannot swivel.

(8) In another embodiment, the castors of the second pair of castors 5 are self-aligning or self-turning according to the direction of rolling (travel) to simplify maneuvering with the travel bag (not shown).

(9) The pair of castors 5 is anchored to the stiffening plate 4 providing stiffness to the travel bag 1 (indicated with dotted line on FIG. 3), which means that for implementing the solution of the invention, the stiffening plate 4 of the bottom of the travel bag 1 must extend at least 50% of the length of the travel bag 1. The stiffening plate 4 may be integrated into the bottom of the travel bag 1, as shown on the figures, or optionally, it may be separately fixed onto the bottom of the travel bag from outside. As shown in FIG. 3, the stiffening plate 4 may be a quadrilateral having opposed front and rear edges with the pair of castors 5 disposed at the front edge and the pair of casters 2 disposed at the rear edge.

(10) In result, the rear part 6 of the travel bag 1 equipped with the stiffening plate 4 resting on the castors 2 and 5 is provided under the travel bag 1 in the extent of approximately 50-65% of the length measured from the rear castors 2, see FIG. 3.

(11) The front part 7 of the travel bag comprising the grab element 3, i.e. 35-50% of the length of the bottom of the travel bag 1, is not equipped with the stiffening plate 4.

(12) This is important to ensure that the front part 7 of the travel bag functions as a brake hindering free rolling of the part with castors 2 and 5, for which purpose the resting slat 8 under the bottom of the travel bag 1 is provided, i.e. when the travel bag 1 is placed on the ground, the front part 7 of the travel bag settles down against the ground, i.e. the resting slat 8 rests on the ground and prevents the rolling of the travel bag 1, see FIG. 2.

(13) When using the travel bag, the user connects to the grab element 3 located at the front part 7 of the travel bag 1 (e.g. if the element itself is not long enough or is provided as a carrying handle) the strap 9 (or cord or string), upon pulling of which the front part 7 of the travel bag 1 is lifted off the ground together with the resting slat 8, after which the travel bag can roll on the castors 2 and 5 behind the user of the travel bag when pulled from the strap 9, see FIG. 1. Strap 9 may be fixed directly to the grab element 3, or when the grab element 3 is provided, for example, as a carrying handle, the ends of the strap may be fixed to the fixing eyelets of the carrying handle (not shown).

(14) In the second embodiment, the mentioned grab element 3 itself is long enough, for example, it is provided as a carrying strap, enabling the user to grab its end and lift up the front part 7 of the travel bag 1—in this case, the strap 9 shown on the figures is not required.

(15) When pulling the travel bag 1 from the mentioned strap 9, the front part 7 of the travel bag is lifted off the ground, because it does not comprise the stiffening plate 4, which enables the travel bag 1 to roll freely on the castors 2 and 5 in the pulling direction of the strap 9.

(16) When pulling the strap 9 is stopped and the front part 7 of the travel bag 1 equipped with the strap 9 is rested on the ground with the resting slat 8, it prevents the rolling of the travel bag 1 on the castors 2 and 5, and the travel bag is fixed on the spot.

(17) Precise lengths of the travel bag 1 and locations of the pairs of castors 2 and 5 depend on the model of the specific travel bag 1 and other structural peculiarities and may thus vary, but more important is that the bottom of the travel bag 1 (rear part 6) must be stiffened from the rear castors 2 to the front castors 5 with, for example, a stiffening plate, the additional pair of castors 5 must be located approximately 50%-65% away from the rear castors 2 of the travel bag 1, and the front part 7 of the travel bag 1 may not be stiffened, but must be able to settle down against the ground when the strap 9 is released, thus preventing any movement of the travel bag.

(18) An advantage of the solution provided with the present invention is that the castors 2 and 5 do not need a separate locking/braking system, because when pulling the travel bag 1 is stopped, the front part 7 of the travel bag lacking the stiffening plate 4 will settle down against the ground due to its weight and is resting on the resting slat 8, whereas this resting slat 8 is acting as a parking brake.

(19) Furthermore, the main weight of the travel bag 1 and the equipment inside the bag is resting on the castors 2 and 5, and for trailing the travel bag 1 the strap 9 should be pulled only to such extent that the front part 7 of the travel bag 1 is lifted off the ground together with the resting slat 8, after which the travel bag 1 will roll behind the user when pulled.

(20) It is also possible to stack other travel bags/trunks and other equipment on the rear part 6 of the bag 1 comprising the stiffening plate 4 and to transport these on the travel bag by trailing the travel bag. This additional weight has no impact on the front part 7 of the travel bag—it can be lifted off the ground with similar pulling force and thus enables trailing the entire travel bag together with additional weight placed on the rear part 6.
