DE202007002714U1 - Boundary and line arrangement for tennis court used by children, comprises slip proof rubber bands wound up on drum - Google Patents

Abstract

A tennis court of a normal size can be used simultaneously by two teams of children when divided transversally. Nets (A,B) are erected, serving two fields. The outer areas are provided with lines formed by slip proof rubber strips secured to the ground with pins guided through sleeves inserted into eyelets or with patches of Velcro(RTM). The strips are wound up when not in use on a drum fitted with a small handle for an easy release.

Description

The The invention serves for the low-effort demarcation of a small field in Tennis, so that children and adolescents can exercise and age better competitions can carry. So far, children's and youth tennis tournaments could only with considerable Effort performed become. The innovation allows it by means of flexible bands to divide a standard tennis court into two children and youth tennis fields. It can then two games take place simultaneously on a standard tennis court. This task is solved by the protection claim 1.

The easy to apply supplementary lines a fast and uncomplicated distribution of the standard tennis court in two smaller fields. This object is achieved by the protection claims 2 to 4th

Protection claim 1:

The Kleinfeld is usually located on an existing tennis court Standard size on a game half of a existing tennis court. A standard tennis court can thereby divided into two small fields.

The elongated Center line of the large field serves half as a cross line (network) of the small field. This will be another network (6 m wide) built. The line of the main field, the serve fields separate from the field in front of the net, serves as elongated in the small field Centerline of the Kleinfeldes.

in the Distance of three meters to this elongated midline of the small field become bands for fixing the elongated Marginal lines of the small field stretched (sketch 1).

Protection claim 2:

The one end of the too exciting band becomes firm in the ground anchoring tubes and there to be introduced retaining pins through two eyelets each at the end of the tape arrested (sketch 2). The anchoring can also be used without a tube. The Band has a width of about 45 millimeters and will end up directly next to the outer lines of the large field over the previously described pins, at least two at each Ends of the band, attached.

Material:

The too exciting band consists of a solid washable stretch rubber, for better clamping force and flexibility at the same stretchability of about 20 percent, or roll-up non-stretchable plastic.

The Pins and eyelets consist of metal or plastic.

Protection claim 3:

to Fixation, in deviation from previous description, are respectively alternatively or additionally the ends and in the middle about 1.5 cm wide Velcro or magnetic tapes for Fixation on the existing bands on the field with corresponding Velcro / magnetic counterparts, attached. The ribbon can thus either with pins alone on the tennis court ground directly or with Velcro or magnetic closures on the lines of the large field at carpet or hard courts attached (pictures / sketch no. 3 and no. 4).

Material:

The too exciting band consists of a solid washable stretch rubber, for better clamping force and flexibility at the same stretchability of about 20 percent, or roll-up non-stretchable plastic.

The Velcro fasteners Made of fabric or plastic, the magnetic closures off Metal.

Protection claim 4:

The Tape is applied to the ground by a hand crank / roller and removed again after use (Sketch # 5).

Material:

The Hand crank consists of a 5.0 cm wide recording coil (Metal, wood or plastic) with a handle loop on the a side surface (Sketch No. 5). It has a diameter of about 20 cm (outside) and inside a diameter of about 4 cm. Here the core consists of one solid material. To roll up the coil has on the other side a rotatable knob (sketch no. 5, A = crank / knob). A coil can use two bands for a small field take up.

The Innovation is evident from the attached pictures / sketches explained.

sketch 1: pitch 6,0 m × 10,97 m

sketch 2: fixing strap with eyelets and pen

sketch 3: fastening strap with velcro closure

sketch 5: Tape on roll, right

Claims (4)
