| (54) | Improved sandal |
| (57) Improved sandal, made of one sole (1) manufactured with a plastic material, wood,
leather or similar, to which the heels (2) are optionally added by conventional means
to the back side of the lower part, as well as soft soles in the upper part, showing
strips (3) allowing to tie the foot of the user to the sole (1) which strips are made
using a tubular body fluorescent to the dark light or actinic light or optionally
they can be built using hollow pipes filled with materials fluorescent under dark
light or actinic light. |
PURPOSE OF THE DEVICE
[0001] This statement refers to a request to Utility Model, referring to an improved sandal, which obvious utility is that it is shaped as an open shoe, built on a convencional sole and strips which strap the said sole to the foot of the user, being the improvement the presence of fluorescent plastic strips.
[0002] These fluorescent plastic strips are designed as bodies emitting fluorescence when receiving irradiation from a source of dark light or hollow pipes filled with fluorescent materials in presence of dark light or actinic light, emitting a visible radiation when placed near light sources of the said types.
AREA OF USE OF THE DEVICE
[0003] This device is used by the shoe industry, more precisely within the industry of manufacturing sandals and the like.
PRECEDENTS OF THE DEVICE
[0004] It is well known the existence and common use of sandals built with one sole, made of a plastic material, wood or leather, to which the heels are fixed in the back of the lower side, and a soft sole in its upper side, with strips able to tie and hold the shoe to the foot.
[0005] The said strips are normally manufactured of leather, plastic, textiles or other similar materials, being optionally decorated with drawings, webs or decoration for aesthetic purposes.
[0006] The applicant is not aware of any sandals in which the strips have a different characteristics which make them essentially different to the extant ones in the market, besides their external shape or decoration.
DESCRIPTION OF THE DEVICE
[0007] The improved sandal suggested by the finding is an obvious novelty within this field of use, since it offers an improved composition of the strips, allowing to closely hold the foot of the user to the sole.
[0008] The sole is made with a base board with the hollow shape of a footprint, to which there are optionally added conventional heels in the back side of its lower part and soft soles in its upper part.
[0009] The strips which tie the foot of the user to the sole, which are fastened to the same means, are made of tubular bodies, full or hollow, fastened to its both ends to the sole, forming arches on the upper part of this, and are manufactured using plastic materials with fluorescent properties, and can be made with conventional tubular bodies filled with fluorescent material.
[0010] The fluorescent material of the filling or which forms the body of the pipes has fluorescent properties when receiving dark or actinic light, glowing in the dark when receiving this type of light only.
DESCRIPTION OF THE DRAWINGS
[0011] In order to complement this description and in order to help to a better understanding of the characteristics of the device, a sheet of drawings is added to this memorandum of description as an integral part of the same, in which, with an illustrative character, but not with a limiting character, the following is represented:
[0013] The drawing N° 2- Shows a particular of one of the possible ways to bind the strips to the sole.
RECCOMENDED MANUFACTURING PROCEDURE OF THE DEVICE
[0014] In the drawings it can be seen how the improved sandal which is proposed is built starting from a sole (1) made of plastic material, wood, leather or similar , to which there are optionally added heels (2) by conventional means to the back side of its lower part; as well as soft soles in its upper part, showing strips (3) which allow to tie the foot of the user to the sole (I); these are made of a tubular body fluorescent under dark or actinic light, although optionally they can be made with hollow tubes filled with a fluorescent material under dark of actinic light.
[0018] In the soles, the heels will have the combinations of layers of polyurethane with the same qualities as the PVC.
[0020] The body of the shoe will be made with elastic and flexible strips of PVC, and can be combined with leather strips according to the part of the foot to be covered, being round anc flat, and placed according to each model.
[0021] The strips of hollow pipe of transparent PVC can be filled with a granulated, transparent PVC auto-fluorescent under the light, as already said before.
[0022] The hollow PVC pipes can be placed in a way that shows a thread forming a round string with different colours, autofluorescent under the said light.
1. Improved sandal, made of one sole (1) manufactured with a plastic material, wood,
leather or similar, to which the heels (2) are optionally added by conventional means
to the back side of the lower part, as well as soft soles in the upper part, showing
strips (3) allowing to tie the foot of the user to the sole (1). These strips (3)
have the characteristic that they are made using a tubular body fluorescent under
dark light or actinic light although they can be optionally built using hollow pipes
filled with materials fluorescent under dark light or actinic light.
